The role of e.coli ESBL+ Literature review Example | Topics and Well Written Essays - 4500 words

The role of e.coli ESBL+ - Literature review Example According to Farrell et al during the period 1999-2000 approximately 1291 bacterial isolates causing UTI were collected from different centres in UK and the most prevalent organism was E. coli which was found to be amoxicillin resistant. Other organisms isolated from UK during this period also included cefruoxime resistant Enterococcus faecalis, Klebsiella pneumoniae and Proteus mirabilis. In UK most of the E. coli causing community acquired and nosocomial infections are CTX-M producing and its control has been a challenge for the clinicians in the past and the years to come. ESBLs may be of different types like TEM, CTX-M, OXA which includes many ESBLs differing in amino acid substitutions. Among the different ÃŽ ²-lactams available, carbapenems were used against ESBL because they are relatively resistant to hydrolysis by most of the ÃŽ ² lactamases. But, however with the advent of carbapenem resistant strains other alternatives like mecillinam and fosfomycin may be used to treat UTIs caused by ESBL producing E. coli with much success. One of the most common problems hovering human females is Urinary tract infection. The annual incidence of UTIs in women is 12 % with the percentage rising to 18.6 % in the case of females aging between 20-25 years. Approximately 40 % to 50 % of women experience UTIs at least once in their lifetime and of these 25-33% experience a recurrence within 6-12 months. Normally, the urinary tract is sterile but bacterial infection may arise from the perianal region leading to UTI. Pathogens in the bladder may remain dormant or irritations and other symptoms like increased frequency of urination associated with pain and burning sensation, presence of blood and/ or pus in urine, nausea and vomiting, cramps or pain in the lower abdomen, fever and malaise in children, strong urine stench, pain during sexual intercourse and increased urgency of urination. Asymptotic bacteriuria may be prevalent in 8% of the

Diffusion and Osmosis Through Dialysis tubing Essay Example for Free

Diffusion and Osmosis Through Dialysis tubing Essay We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain or lose mass. If the dialysis tubing is submerged in different substance than what is in the tubing then some of the dialysis tubings will lose mass and some will gain mass. To begin this experiment we filled 5 dialysis tubings with one of the five substances: water, egg white, NaCl, glucose, or sucrose. The equipment used was: 5 dialysis tubing, a scale, bekers, water, egg white, sucrose, glucose, NaCl, and 5 cups. We put the five dialysis tubing filled with one of the five substance into a cup filled with one of the substance: water, egg white, NaCl, glucose, or sucrose. Then we let them sit in there for 30 mins then took them out of the cups and remassed them. The dialysis tubing did let some of the different solutions in but not all of them. Most of the dialysis tubing gained mass and some lost some mass as well. We found that the substances go from an area of high concentration to an area of low concentration. The data supports our purpose of doing this experiment to find out what happens when a substance in a dialysis tubing is put into a cup of a difference substance to see which ones gain mass and which ones lose mass. A pattern of the data is that the control group did not gain or lose mass. Two of the substances gained mass and two of the substance lost mass. Our results proved our hypothesis that some of the dialysis tubings would gain mass and some of the dialysis tubing would lose mass. Because two of the dialysis tubings gained mass and two of the dialysis tubings lose mass it just shows that the substances went for an area of high concentration to an area of low concentration. A few errors of our experiment is that we could have not used enough of the substances in the dialysis tubings or we could have left the dialysis tubings the cups of substance for a long amount of time which could have changed our results majorly because the more time the dialysis tubings sit in the cup of substances the more they had time to diffuse. Osmosis through Dialysis Tubes We performed this experiment to see how water moves across a semi-permeable membrane. We filled the dialysis tubes with different Mole concentrations of sucrose, and we used our knowledge of osmosis to figure out the different concentrations. If the dialysis tube increases both in size and weight, then that dialysis tube had the highest mole concentration of sucrose. We learned that during osmosis, a form of passive diffusion which means that it requires no energy to move across the membrane, water will always move to the area where the water concentration is lower, so if the sucrose has a high mole concentration then the water will move into the bag since there is less water there, and if the bag has a low mole concentration then there will be little water moving into the bag since there is already a relatively high concentration in the bag. The materials we used to conduct this experiment were: 6 Dialysis Tubes, 6 different mole concentrations of sucrose (0 M concentration, 2 x 10⠁ »Ã‚ ¹M concentration, 4 x 10⠁ »Ã‚ ¹ M concentration, 6 x 10⠁ »Ã‚ ¹ M concentration, 8 x 10⠁ »Ã‚ ¹ M concentration, 1 M concentration), 6 cups to hold the water, a scale to weigh the mass of the dialysis tubes before submerging the bags in water and after. To begin this experiment we first filled the bags with the different mole concentrations of sucrose, the different concentrations were color-coordinated with different colors for a different concentration. Next we weighed the mass of the bags before submerging them in the water, and filled the cups with water so that we could submerge the tubes. After the bags were massed and the cups were filled with water we submerged the bags for 30 minutes. After the 30 minutes were up we took the bags out of the water and blotted them off with a dry paper towel. Finally we massed the bags and recorded our results so that we could compare them with the results from before we submerged the tubes. After analyzing our results we concluded that the Blue substance was water, because it gained no mass, The purple substance was the 2 x 10⠁ »Ã‚ ¹ M concentration because it gained little mass, more than the blue substance. The light green substance the 4 x 10⠁ »Ã‚ ¹ M concentration because it gained some mass, more than the 2 x 10⠁ »Ã‚ ¹ .concentration but not as much as the 6 x 10⠁ »Ã‚ ¹ M concentration. The red substance was the 6 x 10⠁ »Ã‚ ¹ M concentration because it gained more mass than the 4 x 10⠁ »Ã‚ ¹ M concentration but less than the 8 x 10⠁ »Ã‚ ¹ M concentration. The green substance was the 8 x 10⠁ »Ã‚ ¹ M concentration because it gained more mass than the .6 Molar concentration but less than the 1 M concentration, and finally the Yellow substance was the 1 M concentration, because it gained the most mass. Our results answered our question, How can you tell the molar concentration of a 0 .2, .4, .6, .8 , and 1 molar concentration of sucrose? Our results showed us that our hypothesis, If the dialysis tube increases both in size and weight, then that dialysis tube had the highest mole concentration of sucrose, was also correct because the Yellow substance gained the most mass out of all the other substances and was also the substance with the highest Molar concentration of 1, and the Blue concentration gained no mass therefore it was water, because if there is as much water on the inside as the outside then no osmosis takes place. Some sources of error for this experiment is that we could have left the solutions in longer, possibly changing our results. Or that we could have also not used enough of the solutions. Diffusion using Potato rounds We are conducting this experiment in order to see what happens during the process known as diffusion across a semi-permeable membrane. Our hypothesis was that if the Molar concentration is higher in a sucrose solution then the potato will lose mass and if the Molar concentration is lower in a sucrose solution then the potato will gain mass. We learned about diffusion and how a semi-permeable membrane only lets certain molecules pass through it. Diffusion is the act of a molecule passively passing through a semi-permeable membrane. This action of diffusion helps regulate the cell’s processes and this is done on a regular basis so that the cell can live and function. For this experiment we needed: 36 potato sticks (18 of a sweet potato and 18 of a regular potato), 6 sucrose solutions (0M, .2M, .4M, .6M, .8M, and 1M), a scale, cups. First what we did was we massed our potato sticks, and recorded them. Next we filled the cups with the different solutions of sucrose and submerged the potato sticks for 30 minutes. After the 30 minutes we massed the potato sticks and recorded the changes and analyzed the previous data with the data we received, here are our results: After analyzing our results, we concluded that the potato sticks in the Blue concentration gained the most mass out of all the solutions, and the yellow concentration grained not mass, but instead lost mass. This is because water will move from an area of high concentration to an area of low concentration. We also calculated the water potential of the potato sticks and found it to be -7.86 for a regular potato and -17.01 for the sweet potato. All of the experiments that we did, the substances had a semi-permeable membrane that only let certain things through it. All of the experiments consisted of putting different substances into cups filled with different solution and seeing if they lost or gained mass dependent on if the amount of water that was in the substances and the solutions. There was a pattern throughout all of the experiments where one of the substances in the cups of solution gained nor lost mass but stayed the same and two of the substances in the cups of solution gained mass and two of the substances in the cups of solution lost mass.

The Neverending Story: A Classic Novel Essay -- Neverending Story

The Neverending Story:   A Classic Novel  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Neverending Story by Michael Ende perfectly draws the image of a successful novel because it’s overall effect on the reader is intimate and it recognizes itself as a different novel from others especially using a metaphor of stories giving birth to other stories.   Considered as a children’s novel, it should be given a chance to prove itself in the realm of other such intelligent novels.

My Social Worker Essay -- essays research papers

For my Social Work interview, I interviewed Professor Lampen. She is a social work professor here at Cornerstone. She is no longer in the profession right now. Before she came to cornerstone to teach she worked as a social worker for about sixteen years.   Ã‚  Ã‚  Ã‚  Ã‚  Professor Lampen started out her schooling by getting her bachelors degree in Psychology. Then, she went on with her schooling and became a Registered Nurse. She decided that she wanted something different so she went back to school and got her Masters in Social Work at Western Michigan University. For her first job she worked at a hospice. There she made home visits to patients. She worked there for about four years and then went on to work at Mary Free Bed Hospital and Rehabilitation Center. At Mary Free Bed she worked mostly with spinal cord and brain injury patients. She said with her back round in nursing that it helped her in the unit. With her medical back round she was able to understand the patients more and help them better with their problems. She worked there for twelve years and now here she is at Cornerstone teaching.   Ã‚  Ã‚  Ã‚  Ã‚  My next question for if she had any advice for someone entering the field of Social Work. She told me to make sure that the field fits you. There are so many different fields in Social Work. Whatever one you choose you have to make sure it fits you and you’ll enjoy working there. She also said that you really have to care about your wor...

Synthesis of Guernica

During the Spanish Civil War, a small Basque village was bombed by German troops. In April of 1937, Pablo Picasso paid tribute to the bombing by creating the painting, Guernica, which showed a horrible scene of corpses and disaster stricken community. In 1985, a replication of Guernica was donated to the United Nations headquarters in New York and was â€Å"hung outside in the Security Council chamber. † In February of 2003, councilmen gathered at the UN in order to hear US Secretary of State Colin Powell build the American case for war against Iraq.Before the procedure could begin, however, the replication was covered with â€Å"a blue curtain and flags of the council’s member countries,† under the notion that it â€Å"was simply a matter of creating a more effective backdrop for the television cameras. † Off the record, some UN officials believe that â€Å"the United States leaned on UN officials to cover the tapestry, rather than have it in the backgro und while Powell or other US diplomats argued for war on Iraq. † This situation relates directly to George Orwell’s 1984.The covering of Guernica is similar to the censorship Orwell condemns in 1984. (Source 4:Walsh) In 1984, everything was censored and citizens were not allowed to think for themselves. Their government, the Party, regulated every aspect of life, from working to sleeping. Everyone was under their control. Even children were taught to censor the things their parents did or said. The government also dictated what was seen in the media, which is how Guernica connects to 1984. The theme of the painting, Guernica, is war.To have this graphic tribute to the loss of innocent lives as the background for one’s speech justifying war is questionable. Just as the Party censored the media in 1984, UN officials were censoring what the public was seeing here. Why would they allow a painting that shows death, heartache, and loss to be the first thing the public saw? This would make the public question the motives of those speaking and make them wonder what there ulterior motives were for waging war against Iraq.If the Guernica would have remained the backdrop for the Secretary of State Colin Powell, the US would have been questioned by not only its citizens, but those of other countries also. When questioned, the US would have lost supporters and cooperation from its sister countries. This would have eventually led to bad relations between countries, which would have affected everyone greatly. In the end, politics is nothing more than a popularity contest.

The U.S. Food Safety System

The U.S. Food Safety System Ensuring food safety is one of those federal government functions we only notice when it fails. Considering that the United States is one of the best-fed nations in the world, widespread outbreaks of food-borne illness are rare and usually quickly controlled. However, critics of the U.S. food safety system often point to its multi-agency structure which they say too often prevents the system from acting swiftly and efficiently. Indeed, food safety and quality in the United States is governed by no less than 30 federal laws and regulations administered by 15 federal agencies. The U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) share primary responsibility for overseeing the safety of the U.S. food supply. In addition, all states have their own laws, regulations, and agencies dedicated to food safety. The federal Centers for Disease Control (CDC) is mainly responsible for investigating localized and nationwide outbreaks of foodborne illnesses. In many cases, the food safety functions of the FDA and USDA overlap; particularly inspection/enforcement, training, research, and rulemaking, for both domestic and imported food. Both USDA and FDA currently conduct similar inspections at some 1,500 dual jurisdiction establishments facilities that produce foods regulated by both agencies. Role of the USDA The USDA has primary responsibility for the safety of meat, poultry, and certain egg products. USDAs regulatory authority comes from the Federal Meat Inspection Act, the Poultry Products Inspection Act, the Egg Products Inspection Act and the Humane Methods of Livestock Slaughter Act. USDA inspects all meat, poultry and egg products sold in interstate commerce, and re-inspects imported meat, poultry, and egg products to makes sure they meet U.S. safety standards. In egg processing plants, the USDA inspects eggs before and after they are broken for further processing. Role of the FDA The FDA, as authorized by the federal Food, Drug and Cosmetic Act, and the Public Health Service Act, regulates foods other than the meat and poultry products regulated by the USDA. FDA is also responsible for the safety of drugs, medical devices, biologics, animal feed and drugs, cosmetics, and radiation emitting devices. New regulations giving the FDA the authority to inspect large commercial egg farms took effect on July 9, 2010. Prior to this rule, FDA inspected egg farms under its broad authorities applicable to all food, focusing on farms already linked to recalls. Apparently, the new rule did not take effect soon enough to allow for proactive inspections by the FDA of the egg farms involved in the August 2010 recall of nearly half a billion eggs for salmonella contamination. Role of the CDC The Centers for Disease Control leads federal efforts to gather data on foodborne illnesses, investigate foodborne illnesses and outbreaks, and monitor the effectiveness of prevention and control efforts in reducing foodborne illnesses. CDC also plays a key role in building state and local health department epidemiology, laboratory, and environmental health capacity to support foodborne disease surveillance and outbreak response. Differing Authorities All of the federal laws listed above empower the USDA and FDA with different regulatory and enforcement authorities. For example, food products under FDAs jurisdiction may be sold to the public without the agencys prior approval. On the other hand, food products under USDAs jurisdiction must generally be inspected and approved as meeting federal standards before being marketed. Under current law, UDSA continuously inspects slaughter facilities and examines each slaughtered meat and poultry carcass. They also visit each processing facility at least once during each operating day. For foods under FDAs jurisdiction, however, federal law does not mandate the frequency of inspections. Addressing Bioterrorism Following the terrorist attacks of September 11, 2001, the federal food safety agencies began taking on the added responsibility of addressing the potential for deliberate contamination of agriculture and food products - bioterrorism. An executive order issued by President George W. Bush in 2001 added the food industry to the list of critical sectors that need protection from possible terrorist attack. As a result of this order, the Homeland Security Act of 2002 established the Department of Homeland Security, which now provides overall coordination for protecting the U.S. food supply from deliberate contamination. Finally, the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 granted the FDA additional food safety enforcement authorities similar to those of the USDA. Cooperation with State and Local Food Safety Systems According to the U.S. Department Health and Human Services (HHS), more than 3,000 state, local, and territorial agencies are responsible for food safety in retail food establishments within their jurisdictions. Most states and territories have separate departments of health and of agriculture, while most counties and cities have similar food safety and inspection agencies. In most states and local jurisdictions, the department of health has authority over restaurants, while the agriculture department is responsible for food safety in retail supermarkets. While the states inspect meat and poultry sold in the state where they are produced, the process is monitored by the USDA’s Food Safety and Inspection Service (FSIS). Under the Wholesome Meat Act of 1967 and the Wholesome Poultry Products Act of 1968, state inspection programs are required to be â€Å"at least equal to† federal meat and poultry inspection programs. The federal FSIS takes over responsibility for inspections if a state voluntarily ends its inspection programs or fails to maintain the â€Å"at least equal to† standard. In a few states, state employees conduct meat and poultry inspections in federally-operated plants under federal-state cooperative inspection contracts.

Representations of Women in Gothic Literature Essays

Representations of Women in Gothic Literature Essays Representations of Women in Gothic Literature Paper Representations of Women in Gothic Literature Paper Throughout the gothic genre, women are seemingly created on two extreme ends of the spectrum as either feeble and innocent victims or vindictive and lascivious predators. The Romantic poetry of Keats encapsulates this dualistic approach to the representation of women because on one hand he does create powerless and vulnerable women, but in order to highlight the decadence of the seventeenth century period of enlightenment, he eradicates the cold-hearted rationalism associated with patriarchy through the emergence of the Femme Fatale. Stoker wrote his epistolary novel, Dracula, amid the fin de siecle, a time period that was strictly governed by the stringent standards of the patriarchal, Victorian society. From the outset, Stoker challenges the rigid gender boundaries of society by making an explicit link between vampirism and sex, as his female characters adopt unconventional roles that appear to place them in positions of power, and in the process subvert the expectations of the Victorian society. Carter’s Bloody Chamber, written during the rebellious feminist era of the 1970’s, is arguably the most transgressive of all of the gothic texts on the basis that she does indeed explore the victimisation of women, but only does so as a means of highlighting the juxtaposing triumph of the female resurgence, as Kathleen E.B Manley asserts that her female protagonists â€Å"oscillate between passivity and action†. From the outset, each writer implies that the passivity which is traditionally associated with femininity is a direct result of the oppression from the patriarchal society. Keats conveys this idea through the objectification of women which is present in Isabella, as he notes that the brother’s plan was to â€Å"coax her by degreesTo some high noble and his olive trees†. Evidently, Keats is making reference to a proposed arranged marriage, thus exploring the way in which Isabella is a commodity to her brothers, with no active fre

Why transfer Essay Example | Topics and Well Written Essays - 500 words

Why transfer - Essay Example We helped raise funds in order to build the bridge, because many children die when crossing the river during flood seasons. I discovered that, though the bridge project was going well, the basic living conditions in the village had not improved.  However, when I visited another village in a different province in China, I was completely shocked to find that the people led progressive lives, while keeping their tradition and culture intact. Instead of remaining in a progressive rut, they parlayed what they knew of their traditional culture into a briskly functioning art and handicraft industry. They actually had a working business model that I did not expect to see in such a backward village. I realized that my dream to help the other village by spoon feeding them was wrong. When I explained to my father that we could actually do much more for the village than what we were already doing, he told me that I had the right idea. But without a solid foundation in Business and Economics, I would not be able to put my theories and plans into reality. Then I realized what my true calling was, and began to follow this new career path. Upon my return to UW, I enrolled in Economics courses and utilizd my free time in a manner that would allow me to mingle and discuss economic theories with my classmates and professors. My diligence and desire have a highly positive relation to the grades that I got in those Economics centered classes. I was averaging a 4.0 in my Macroeconomics, Statistics, and Business Law classes. I enjoyed dipping my feet in the School of Business and Economics pool, and my interest was further fueled by my participation in an information technology project at the Foster School of Business at UW. My impressive performance has convinced me that I am truly ready to become a Business and Economics

What is the nature of the controversy between Christians and Essay

What is the nature of the controversy between Christians and evolutionists - Essay Example However, the evolutionists disagree with the spiritual aspect of man and the existence of God. Most of the evolutionists are agnostics or atheist; they believe that the existence of the universe is a never-ending cycle. Evolutionists believe that man is born, has the ability to live and survive, and dies. For them, there is no life after death and that men are created in order to struggle to survive and not to abide from the Scriptures of God; in this case, ethical principles are more important than religious obedience. For the evolutionists, people must be taught with the ethics of the existence of the universe and life per se while the Christians believe that people must learn from the Scriptures in order to gain the life that is set to them after death (Gibbs, 2005). Since time immemorial, these two views have been battling the grounds of the beginning of life and the creation of the earth and the universe. Nonetheless, the nature of the controversy behind is that, up until today, the decision lies within the

Pre lab springs Assignment Example | Topics and Well Written Essays - 250 words

Pre lab springs - Assignment Example The theoretical y-intercept in the standards equation of a straight line compares (corresponds) to the determined value of T2. The slope (constant) is normally represented by the value of m in the standards equation of a straight line and in this case corresponds to K d. c. Again, compare the standard form of the equation for a straight line and the result for part (a), what should the theoretical value for the y-intercept be in terms of constants and the dynamical spring constant k d and m0 the effective mass of the spring? In terms of the y-intercept (and other known values), what is the value of the effective mass of the spring m0? As argued above, the standard equation of a straight line is y= mx +c. This equation implies that y is the same as c since it is the value where the line cuts the y-axis. C is the intercept on the y-axis. In comparison, if T2 compares to y, and T2=1.61, then it means that the straight line of the graph of T2 against m cuts the x-axis at 1.61. This value depends on the constant K d, since the spring constant results from the resultant forces applied on the spring, the restoring force and the mass, mo applied on the

The Customer Analysis and Market Segmentation Essay

The Customer Analysis and Market Segmentation - Essay Example The study shows that producers need to create commodities on high demand thus, the need to make potential estimates. While marketing industrial grinding machinery, a marketer will have to make four decisions, which include; the pricing decisions, the product decisions, the placing decisions and the promotion decisions. Under the product decisions, the marketer will first have to decide on the quality, brand name, and functionality of the machinery. Depending on the potential estimates made and the potential customers being targeted, the standards set can be high or low. Marketers need to consider this because for instance; some brand names will appeal to some customers while to others they may not make any sense at all. The pricing decisions are highly critical since they determine the profit-making of the organization. The marketer should ensure that the price set is in accordance with the potential estimates made. Prices should not be exceptionally high since this may cause custome rs to shift to the competitors. In making this decision, marketers should evaluate the prices of other grinders in the market. The marketer also has to decide whether discounts will be issued on the machinery or not (Pride & Ferrell, 2011). Under the placing decisions, the marketer has to decide on the distribution of the grinding machinery. Depending on the potential estimates made concerning the market available, the marketer has to decide which places to distribute the product and which to be left idle. Transportation decisions also have to be considered, and the number of distribution channels. However, most distribution centers should be placed where a wide potential market has been identified. Promotion decisions include the various ways in which the marketer can market the product. Different marketers will use different strategies of marketing a product depending on its type. For instance, marketing grinding machinery would need a method such as personal selling to ensure tha t the customer is totally made aware of the product and its functioning. However, other methods of marketing such as advertising might leave some information about the product. 2) What is the relationship among market segmentation, target marketing, and positioning? What will happen to a company’s target marketing and positioning efforts if markets are incorrectly or not effectively/insightfully segmented? Market segmentation refers to the division of the customers of a product in different groups. Customers will mainly be divided depending on their needs, their characteristics and their financial ability. While segmenting the market, the marketer also has to consider the organization’s ability to satisfy all the segments and the competitive advantage of each segment. Other factors that have to be considered in evaluating the segmentation includes; the costs of the product and the sales estimates (Pride & Ferrell, 2011). Once the business has divided its market into di fferent segments, it then evaluates the potential gains of each market and then chooses which to concentrate on. This process is referred to as target marketing. The market chosen is then referred to as the target market.

To begin with, every plan and project has to have goals and objectives to be met and therefore ample time ought to be invested so that all relevant information is table. In case of fire, some on the things to consider are how the fire outbreak can occur. In some instance, fire occurs outside the premises while in few instances inside the building. The major question then is how one will handle such a case in either case. There is therefore a need to have a plan. The initial step in designing a good plan for fire emergency is to contact personnel who have dealt with such cases, for they have a wide knowledge of past experience in disaster management and therefore they would be fundamental assets for a viable emergency management fire plan (Hanna, 2008). A good plan should define basin emergency terminologies and diagrammatically show any symbol associated with fire emergency and a clear definition of the symbol and its use and purpose. This is because the team that comes up with the plan may not be the same team that will put the plan into operation. The sequential steps and measures to pursue, incase of fire breakout, should be sequential enough and easy to implement. Furthermore, a good plan should have a list of appendix to give easy reference of information within the plan. In addition, a good plan should also be able to achieve its objectives perfectly well and also it should be subject to amendment. Assuming that fire outbreak from outside, some of the objectives many include one, to ensure that the larger mass of patients who possible could be outside are well controlled in order to avoid any casualty. Secondly, in case of fatalities, first aid ought to be administered instantaneously to avoid further complication. In addition to that, the medial care should come up with ways of ensuring that the available

The Customer Analysis and Market Segmentation Essay

The Customer Analysis and Market Segmentation - Essay Example The study shows that producers need to create commodities on high demand thus, the need to make potential estimates. While marketing industrial grinding machinery, a marketer will have to make four decisions, which include; the pricing decisions, the product decisions, the placing decisions and the promotion decisions. Under the product decisions, the marketer will first have to decide on the quality, brand name, and functionality of the machinery. Depending on the potential estimates made and the potential customers being targeted, the standards set can be high or low. Marketers need to consider this because for instance; some brand names will appeal to some customers while to others they may not make any sense at all. The pricing decisions are highly critical since they determine the profit-making of the organization. The marketer should ensure that the price set is in accordance with the potential estimates made. Prices should not be exceptionally high since this may cause custome rs to shift to the competitors. In making this decision, marketers should evaluate the prices of other grinders in the market. The marketer also has to decide whether discounts will be issued on the machinery or not (Pride & Ferrell, 2011). Under the placing decisions, the marketer has to decide on the distribution of the grinding machinery. Depending on the potential estimates made concerning the market available, the marketer has to decide which places to distribute the product and which to be left idle. Transportation decisions also have to be considered, and the number of distribution channels. However, most distribution centers should be placed where a wide potential market has been identified. Promotion decisions include the various ways in which the marketer can market the product. Different marketers will use different strategies of marketing a product depending on its type. For instance, marketing grinding machinery would need a method such as personal selling to ensure tha t the customer is totally made aware of the product and its functioning. However, other methods of marketing such as advertising might leave some information about the product. 2) What is the relationship among market segmentation, target marketing, and positioning? What will happen to a company’s target marketing and positioning efforts if markets are incorrectly or not effectively/insightfully segmented? Market segmentation refers to the division of the customers of a product in different groups. Customers will mainly be divided depending on their needs, their characteristics and their financial ability. While segmenting the market, the marketer also has to consider the organization’s ability to satisfy all the segments and the competitive advantage of each segment. Other factors that have to be considered in evaluating the segmentation includes; the costs of the product and the sales estimates (Pride & Ferrell, 2011). Once the business has divided its market into di fferent segments, it then evaluates the potential gains of each market and then chooses which to concentrate on. This process is referred to as target marketing. The market chosen is then referred to as the target market.

In the near future,cities will need to become increasingly energy Essay

In the near future,cities will need to become increasingly energy efficient. Outline at least three strategies for energy efficiency and their advantages for modern cities.Refer to one or more cities - Essay Example It is leading the world by example in energy efficiency despite being the home of one of the best mass rail transit networks, holding dense urban population and a high-tech neon-lit lifestyle. Their wide usage of electric heat pumps (EHP) gives them the ability to maintain low carbon emission profile. Furthermore Tokyo also utilizes water and thermal energy using EHP, which is broadly accessible around Tokyo districts. If things go as planned, Tokyo could possibly be among world’s lowest carbon emitting cities. Tokyo’s energy efficient ways are different and somewhat better than western conventional simulations (Hitoshi & Yoshitaka, 2008. Page; 1). This small essay looks at various methods employed by Tokyo which is one of the most populated cities of the world. And looks more closely at some selected methods those stand out from the rest that Tokyo incorporates to save energy. First one is the reduced consumption of gasoline and reduction in greenhouse gases. The second factor for energy efficiency is Thermal Power production and the last factor in this essay is the Lifestyle of the people of Tokyo. Tokyo is a jam packed city and this is a compliment. The city is well equipped with railway transit system which considerably reduces fuel consumption; people either use public transport, ride a bicycle or simply walk to their work. Preference to buy a house near railway station is significantly high and apartment prices drop if they are located far away from such public facilities. Transit Oriented Development (TOD) is well on its way in Tokyo. Moreover the structure of buildings is such that it accommodates more people by occupying less space. Road network throughout Tokyo is dense and is made for the primary purpose of walking. People of Tokyo are accustomed to this style of life which enables them to efficiently use their energy resources (Hitoshi & Yoshitaka, 2008, page; 2). Other factor that contributes to energy efficiency is Tokyo Metropolitan

Morality and People Essay Example for Free

Morality and People Essay Due to recent occurrences in history, the U. S. has found itself in various situations where serious questions have arisen about the way that we treat our prisoners of war. The question has been posed: should we torture someone if it means that we will gain information that will protect a large number of people? A person with a utilitarian view might suggest that because the torture would bring about the right information that would save many people, it would be ok to torture someone. This view holds that any action is good if it is beneficial to the majority of the people involved in the question. Furthermore, a person who believes in Kantian duty-based ethics might say that the torturing of any individual would be wrong in any circumstance. A person with this type of view would answer this way because they believe that the result of the information being gathered from the torture would not justify the wrong act of torturing someone and that the act of torture is wrong because of the motive of the torturer. This is because a person who believes in Kantian duty-based ethics contends that right and wrong is not based upon the actions of the one performing the torture but rather the motive behind the action, which would appear to be good but in reality would be wrong because of the desire to hurt another person. In addition, a person who believes in virtue ethics would question the character of the people performing the torture and determine whither the action is right or wrong based on if the person had right or wrong motives. Lastly, a person who believes in Christian-principle based ethics would argue that it is always wrong to torture people in any situation. I believe that this theory is the strongest and most appropriate. Even thought the act of torturing someone in some cases could potentially help to protect a large number of people, the fact is its wrong. I don’t believe that we should fight evil with evil. Rather, I believe that there are many other options that we can take up in the fight against terror and evil that don’t involve compromising on our values.

The History Of The Kitchen Refrigerators

The History Of The Kitchen Refrigerators Today, refrigerators have become an essential part of every kitchen (Tatum, 2010). Refrigeration is used to store meat, vegetables among other foodstuffs at low temperatures, thus inhibiting spoilage due to microbial activity. The process of essentially, manufacturing or making a refrigerator was gradual and begain in the 18th century. It culminitated with Carl von Lindens work in 1876. (Bellis, 2010 Tatum, 2010) Evidence suggests that since 500 AD, man has known to produce ice by natural processes. Egyptians and Indians made ice on cold nights by setting water on earthenware pots. Later on in the 1700s, England servants in the 1700s collected ice in the winter and put into icehouses, which then provided cool storage in the summer. (Bellis, 2010 Tatum, 2010) In 1748, William Cullen of the University of Glasgow developed an entirely new process that consequently lead to an artificial cooling medium being developed. (Tatum, 2010). His experiment produced ice. However; he was unable to explain what it meant. Around 1805, the Oliver Evans was involved in designing a refrigeration apparatus, but unfortunately, he didnt build one until Robert Perkins improved on his creation in 1834. (Bellis, 2010). Thomas Moore coined the word refrigerator for these machines. However, as today Perkins and Evans machines are called iceboxes. In 1844, Dr. John Gorrie, a physician, was able to construct a working unit that was based on both Evans and Perkins model. constructed. It was because of a outbreak of yellow fever that led to Gorrie creating the unit, which was used to cooling the air. (Bellis, 2010 Tatum, 2010) Gorrie is credited as being the one who invented the refrigerator by many. (Bellis, 2010) However the situation began to change, when Carl von Linde (1842-1934), a German mechanical engineer published an essay on improved refrigeration techniques, in 1871. He proposed a continuous process of liquefying gases in large quantities. In 1873, he invented the first practical and portable compressor refrigeration machine. (Tatum, 2010) He obtained a patent for his refrigerator in 1877 from the German Imperial Patent Office. He made use of gases namely ammonia, sulphur dioxide and methyl chloride. (Bellis, 2010 Tatum, 2010) In the 1900s, various refrigeration models were seen. Noteworthy refrigerator models included Servel, Frigidaire, Electroflux among others. (Bellis, 2010) These models of the 1900s had several advancements since designs of pioneers such as Gorrie. By 1918, automatic controls were part of some models already. (Tatum, 2010) The gases used namely ammonia, sulphur and methyl chloride were replaced by Freon in the 1920s in order to comply with safety standards. When one looks at the history, it shows that in 1918, automatic parts were already installed. This included automatic dials that aid in the operation. It was rather unfortunate that the units were not self contained as different parts were separately placed from each other. It wasnt until 1923 that self contained refrigerators began appearing. (Bellis, 2010) Ice cube trays were also introduced. (Tatum, 2010) Although many advancements were made, the modern refrigerator was put in mass production until 1946 i.e., after the World War II. (Bellis, 2010 Tatum, 2010) People, in the the 1950s and 1960s were the ones that witnessed a variety of technological innovations by engineers and scientists of the day. Among them were: (i) automated defrosting and (ii) making of ice. Today, there are many features that are intertwined with the features of the olden days and includes power failure alerts, ice cabinets among others. (Bellis, 2010 Tatum, 2010) To present, domestic refrigerators are present in almost every home worldwide. Due to the models created by Gorrie, Cullen, Carl von Linche among others, the refrigerator has thus become one of the machines or applicances that is integral to us every day. (Bellis, 2010 Tatum, 2010) TYPES OF REFRIGERATORS Refrigerators are classified into three types: (Suyambazhahn, 2009) Air refrigerator Vapour compression refrigerator Vapour absorption refrigerator VAPOUR COMPRESSION REFRIGERATION SYSTEM The vapour compression refrigeration system is most commonly used in refrigerators. A refrigerant is a gas with characteristics that make is suitable for refrigeration and air conditioning. R-22 is a commonly used refrigerant. This cycle works in four phases, which are described later on because it is similar to the refrigeration cycle. Figure 1 Vapour compression refrigerator (Suyambazhahn, 2009) This type has various uses such as: (Suyambazhahn, 2009) Air conditioned cinema theaters, restaurants, hospitals, residential buildings for comfort. Advanced medicines which are manufactured and preserved only in special atmospheric conditions. Preservation of food products. VAPOUR ABSORPTION REFRIGERATION SYSTEM The principle of vapour absorption was first discovered by well known scientist Michael Faraday in 1825. But this concept is applied to refrigeration during 1860s by French Scientist Ferdinand Carve. The commonly used refrigerant for vapour absorption system is ammonia, NH3. In order to change the conditions and phase of refrigerants, heat energy is utilized in vapour absorption system where as mechanical energy is utilized in vapour compression systems. In a vapour absorption system, compressor is replaced by an absorber, a pump and a generator. The vapour at the low pressure that leaves the evaporator is then moved to the absorber. The absorber contains weak ammonia solution. The vapour leaving from the evaporator is dissolved in the weak ammonia solution to form a strong solution. Cooling water is used to cool he absorber. The strong solution from the absorber is pumped to the generator. The strong solutions pressure is increase by the pump (10 bar) and is circulated through the system by pump. Figure 2 Vapour absorption refrigerator schematic (Rajadurai, 2009) COMMONLY USED REFRIGERANTS Even though there are many types of refrigerants which are used in various applications, the following types are important from the subject point of view. AMMONIA It is the most widely used refrigerant. It is mainly used as the refrigerant in cold storage plants and also in ice making plants. Its boilined point at atmospheric pressure is -33 oC and it has a high latent heat and high critical temperature which are desirable properties of ammonia as a refrigerant. Also it is less expensive. But its usage becomes secondary due to the following characteristics: (Rajadurai, 2003) It is toxic It is flammable It has an irritating odour It attacks metals like copper and brass in the presence of moisture CARBON DIOXIDE The demerits involved in the usage of ammonia can be eliminated by using carbon dioxide. It is non toxic and odourless. It has a boiling point of -77.6 oC at atmospheric pressure. But it is not so often used because of its high operating pressure that is the operating pressure of CO2 is very high as 70 bar. (Rajadurai, 2003) SULPHUR DIOXIDE It has a boiling point of -10 oC at atmospheric pressure. IT has a very low working pressure and a large latent heat with a high critical temperature. It is non flammable and on explosive. Even though there are many positive characters mentioned, the SO2 refrigerant is very toxic and it has an irritating pungent odour. Also it is very corrosive in contact with moisture. (Rajadurai, 2003) FREON 12 (or DICHLOR DI FLUOROMETHANE) It has a boiling point of -30 oC at atmospheric pressure. It is non toxic, non explosive and on flammable. It is odorless and colourless. It is non corrosive to any metal. But it is highly costlier than other types of refrigerators. But the main demerit with respect to this is type is the large amount of refrigerant that is necessary to be circulated for a given output. It is generally abbreviated as R-12 or F-12. (Rajadurai, 2003) FREON 22 (or DICHLOR MONO CHLORO METHANE) It is widely used as the refrigerant for domestic refrigerants. It has all positive points like the characters posed by Freon 12 such as non toxicity. It is colourless, odourless and non corrosive to metal. Additionally, the amount of refrigerant required is only 1.3 kg/min per tonne for refrigeration. (Rajadurai, 2003) PRINCIPLES OF OPERATION THERMODYNAMICAL CONSIDERATION THE SECOND LAW The second law of thermodynamics is described as the most fundamental law of science (Khemani, 2008). It is fundamental in the sense that it can be used to explain not only refrigerators and heat engines but highly advanced phenomena such as the big bang. It has been put aptly in the words of Classius as it is impossible for a process to occur that has the sole effect of removing a quantity of heat from an object at a lower temperature and transferring this quantity of heat to an object at a higher temperature (Mortimer, 2008). This essentially means that heat cannot flow spontaneously from a cooler to a hotter body if nothing else happens (Mortimer, 2008) i.e. there needs to be an external agency to effect the change. In kitchen refrigerators, the closed box inside is able to be kept cool by the removal of heat from the inside of the box and deposits it to the outside. As per the second law, the heat will not move from the cold to the hot freely so it is important for it to be made to do so, this is done by using an intermediate fluid (Littlewood, 2004) which absorbed heat on the inside. This intermediate fluid is known as a refrigerant and carries the heat outside of the box whereby it it released into the air as heat as shown in Figure 3 (Littlewood, 2004). Figure 3 the flow of heat within the refrigerator a schematic (Littlewood, 2004) The fluid circulates within the pipe which passes in and out and can be found at the back of the refrigerator. It is kept by using a compressor (which uses electricity from the home) and allows it to work effectively without violating the second law of motion. (Littlewood, 2004) THE FIRST LAW Refrigerator takes in energy from a region that needs to be cooled and deposits this heat energy into some other region that is outside of the refrigerator. In order to do work, there needs to be some mechanism in place, where the work done by a compressor and its electric motor is utilized. Using the First Law of Thermodynamics we can write: (Littlewood, 2004) Figure 4 the first law of thermodynamics (Littlewood, 2004) QC QH = -W Where: Qc energy or heat of the cold system QH = energy or heat of the hot system W = work done Since work is done on the refrigerator by the compressor, the work is done is deemed negative because of sign conventions. This is part of the first law (Littlewood, 2004). The refrigerator is termed as a closed system and it possesses a constant composition: U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) V dT U = U + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) T dT dU = (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡V) T dV + (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T) V dT According to Bain (2010), there are four basic parts to any refrigerator: Compressor Heat Expansion valve Refrigerant The exchanging pipes are a coiled set of pipes that is placed strategically outside of the unit. The refrigerant as will be discussed later on is a liquid that has the ability to evaporate efficiently so that inside the refrigerator is kept cooled. (Bain, 2010) A gas can be cooled by adiabatic expansion if the process is enthalphic. The gas expands through a process barrier from one constant pressure to the next and the temperature difference in observed. Insulation of the system made the process adiabatic. The result is that a lower temperature was absorbed on the on a low pressure side and the change in the temperature is proportional to the change in pressure. (Bain, 2010)  Ã¢â‚¬Å¾T  µ  Ã¢â‚¬Å¾P Figure 5 schematic of a domestic refrigerator (Bain, 2010) Figure 6 heat transfer within a refrigerator (Popular Mechanics, 1993) When an energy |qc| is removed from a cool source at some temperature Tc, and then deposited in a warmer sink at a temperature Th, the change in entropy is: (Atkins dePaula, 2006) Atkins dePaula (2006) also indicated that the process is not spontaneous because the entropy generated in the warm sink is not enough to overcome the loss of entropy from the cold souce. And because of this more energy needs to be added to the stream that enters the warm sink to generated the entropy required by the system. They further indicated that the outcome is expressed as the coefficient of performance, c: The less the work required to achieve a given transfer, the greater the coefficient of performance and the more efficient the refrigerator (Atkins dePaula, 2004). Because |qc| is removed from the cold source, the work |w| is added to the energy stream, the energy deposited as the heat in the hot sink |qh| = |qc| + |w|. Therefore, From: We can have an expression in terms of the temperature alone, which is possible if the transfer is performed reversibly (Atkins dePaula, 2006): Where: c = thermodynamic optimum coefficient of temperature Tc = temperature of the cold sink Th = temperature of the hot sink For a refrigerator, it important that a very low coefficient of performance. For a refrigerator withdrawing heat from ice cold water (Tc = 273 K) in a typical environment (Th = 293K), c = 14. As an example, to remove 10 kJ (enough to freeze 30 g of water), requires transfer of atleast 0.71 kJ as work. (Atkins dePaula, 2006) The work to maintain a low temperature is very important when designing refrigerators. No thermal insulation is perfect, so there is always some form of energy flowing as heat into a specific sample at a rate that is proportional to the temperature difference. (Atkins and de Paula, 2006). Figure 7 (a) the flow of energy as heat from a cold sink to a hot sink is not spontaneous as described the first law. Notice that the entropy increases but it is larger for the hot sink as compared to the cold sink. (Atkins dePaula, 2006). This contributes to a decrease in the NET entropy. (b) The process becomes feasible if work is provided to add to the energy stream. Then the increase in entropy of the hot sink can be made to cancel the entropy of the hot source (Atkins dePaula, 2006) The rate at which energy leaks happen is written as: Where: A = a constant that depends on the size of the sample and details of the simulation Tc = temperature of the cold sink Th = temperature of the hot sink The minimum power, P, required to maintain the original temperature difference by pumping out that energy by heating the surroundings is: As can be seen the power increases as the square of the temperature difference (Th Tc). THE REFRIGERATION CYCLE The gas is pumped continuously at a steady pressure, the heat exchanger (which brings the required temperature) and then through a porous plug inside container that is thermally insulated. A phase change heat pump uses a liquid, as described earlier, that has a very low boiling point, which is used to move heat from an area where it is cooler to one where it is warmer. The refrigerant requires energy so that it can evaporate, which essentially allows it remove the heat from the surroundings by absorbing it. When the vapor condenses, the energy absorbed in the process is released which is also in the form of heat as might be expected. A refrigerant is a compound used in a heat cycle that undergoes a phase change from a gas to a liquid and back. Latent heat describes the amount of energy in the form of heat that is required for a material to undergo a change of phase (also known as change of state). Two latent heats are typically described. (Bambooweb, 2009)For other uses, see CFC (d isambiguation). The pump operates a cycle in which the refrigerant changes state from its liquid form to the vapour form and vice versa. This process occurs repeatedly and I known as the refrigeration cycle. In this cycle, the refrigerant condenses and heat is released in one point of the cycle. It is the boiled (or evaporated) so that it absorbs heat in another point of the cycle. The widely used refrigerant is hydro fluorocarbon (HFC) known as R-134a and CCl2F2 (dichlorodifluoromethane). Other substances such as liquid ammonia, propane or butane, are be used but because of their highly flammable nature, they are disregarded as a good refrigerant. 1930 (MCMXXX) was a common year starting on Wednesday (link is to a full 1930 calendar). (Bambooweb, 2009)For other uses, see CFC (disambiguation). In the refrigerator the fluid used (e.g. CCl2F2 ) fluid is liquefied by compression then vaporized by sudden expansion which gives a cooling effect. The compressor, in itself does not create a cooling effect directly, as might be expected. The cooling effect is fashioned when the refrigerant absorbs the heat so that it is removed and the area becomes cooler. This is accomplished with a heat exchanger. (Bambooweb, 2009)For other uses, see CFC (disambiguation). A heat exchanger is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted. The refrigeration cycle can be divided in two parts: The liquefaction stage The evaporation stage LIQUEFACTION STAGE The refrigerant vapour undergoes recycling by itself into the liquid form by the extraction of heat from a vapour at a higher temperature. The refrigerant is compressed by the compressor where a low pressure and low temperature condition is created. This is accomplished by an evaporating coil. During the compression process, the vapour of the refrigerant undergoes a temperature change (as an effect of the compression process). Additionally, the work of compression to create the high temperature and pressure vapour also contributes to the temperature change experienced by the vapour. The condenser that is located where the temperature is higher (i.e. the higher temperature heat sink) collects the vapour. Heat is then removed from the refrigerant and in lieu of this it condenses to its liquid state, hence the name for the condenser. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) Using the Joule-Thompson coefficient: For a perfect gas  µ = 0 Cp + Cv = (à ¢Ã‹â€ Ã¢â‚¬Å¡H/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p Introducing: H = U + pV = nRT into the first term: Cp Cv = (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p + nR (à ¢Ã‹â€ Ã¢â‚¬Å¡U/à ¢Ã‹â€ Ã¢â‚¬Å¡T)p = nR EVAPORATION STAGE As the refrigerant leaves the condenser, the next part of the cycle begins. This is accomplished when a high temperature and high pressure liquid passes through a metering device that is found within the refrigeration. The valve allows a specific quantity of liquid coolant to pass into the evaporation chamber. Evaporation chambers are relatively low pressure and this encourages coolant evaporation. Newly evaporated coolant is drawn though the cooling coils (typically a fan is used to blow air over the coils). Thus, the evaporative process produces the cooling effect. The refrigerant then is pulled to the compressor in the suction line where it will be compressed into a high temperature, high pressure gas and sent to the external heat sinking coils. Capillary action or capillarity is the ability of a narrow tube to draw a liquid upwards against the force of gravity. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) A refrigerator pumps heat up a temperature gradient. The cooling efficiency of this operation depends on the amount of heat extracted from the cold temperature reservoir (the freezer compartment), , and the work needed to do so. Since a practical refrigerator operates in a cycle to provide a continuous removal of heat, for the cycle. Then, by the conservation of energy (or first law), , where is the heat ejected to the high temperature reservoir or the outside. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) The measure of a refrigerator performance is defined as the efficiency expressed in terms of the coefficient of performance (). Since the purpose is to extract the most heat () per unit work input (), the coefficient of performance for a refrigerator, , is expressed as their ratio: (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) Where, the conservation relationship given above is used to express the work in terms of heat. For normal refrigerator operation, the work input is less than the heat removed, so the is greater than 1. Refrigerators are commonly referred to as heat pumps of more specifically a it is a reversible heat pump because they basically pump heat. (Mortimer, 2003 ; Brain, 1994 ; Bellis, 2010) Figure 8 A diagram of the vapor compression refrigeration cycle that is used in heat pumps. The cycle shows the following: (i) condenser, (ii) expansion valve, (iii) evaporator, (iv) compressor. (Karin, 2003) It is commonly believed that by opening a refrigerator, itll cool the kitchen. However this is entirely opposite, opening a refrigerator or freezer heats up the kitchen because the refrigeration cycle does not accept the air from the outside (Karlin 2003). The heat is referred to as the heat dissipated from the compressors work and also includes that heat that s removed from within the refrigerator as well. (Karlin, 2003) The COP (in a heating or cooling application), provided that it undergoes steady state operation, is given by the following equation: Where: ΆQcool is the heat extracted from a cold reservoir, ΆQhot is the heat delivered to a hot reservoir. ΆA is the dissipated work by the compressor. THE CARNOT ENGINE The Carnot refrigerator is the maximum limit to the COP (efficiency) of a refrigerator system. Although we cannot make the carnot refrigerator, it tells us the maxium or best performance that can be garnered from a real refrigerator. The carnot refrigerator is sort of ideal in its design. As described earlier by Atkins dePaula (2006) with the Carnot engine, the COPc of a Carnot refrigerator depends (i) the temperature of the region that needs to be kept cool which has a characteristic temperature, TC and the temperature of the region where the heat needs to be transferred to, having a characteristic temperature, TH. It is equal to: (Littlewood, 2004) EFFICIENCY The efficiency of a refrigerator is described by a special coefficient known as a coefficient of performance and is defined in terms of the following parameters: SUMMARY OF THERMODYNAMICS OF A REFRIGERATOR AFTER ONE CYCLE Change in internal energy = 0 Change in heat is > 0 Total work > 0 Total volume change = 0 Change in Gibbs free energy = 0 Entropy change of the system = 0 Entropy change of the universe > 0

Analysis- Software Solutions :: Computer Science

Analysis- Software Solutions In order to make my database I am going to use Microsoft Access. Other possible systems I could have used are programmes such as Microsoft Excel and also a simple manual system where all the data is hand-written. I chose Microsoft Access, as this is more efficient and more professional as a whole. If I used a manual system I could have improved my problems by having all of the documents filed in alphabetical order, having more filing cabinets or by writing out documents more neatly and more tidily. Filing all documents in alphabetical order would have tidied up the documents and made them easier to find, but as documents would still be in a filing cabinet even though in alphabetical order it would still be time consuming to find them rather than a computerized system which would be a lot faster to find and therefore less time consuming. Also if you use more filing cabinets in which to store documents this may still not be very practical if the person the changes are designed for works in a small office with limited space. As well as this, by taking more care in writing and filling in documents and writing more neatly this would improve the system but it would also be inappropriate at times. This is because you are unable to take care and write neatly all of the time, as there are many occasions in which you are rushed which causes the neatness of your writing to falter. The final reason why I have opted to use Microsoft Access rather than a manual system where filing cabinets are involved is because in Access you can store about 20,000 files but if you had to store 20,000 files using a manual system huge amounts of space would be taken up and it would be very awkward to find the specific document you desire. If I used Microsoft Excel in which to store data this would improve on the current system as it is computerized but it is still not as efficient as other computerized programmes. Microsoft Excel would allow me to create tables, perform calculations, print out single documents and also print out multiple documents. Being able to print out improves on a manual system as it is a lot quicker and you do not have to keep typing documents out time and time again. Although using Microsoft Excel is a large improvement on using a manual system Microsoft Access is the one I have opted to use. This is because on Microsoft Access you are able to perform all actions

Employment Skills Introduction   Ã‚  Ã‚  Ã‚  Ã‚  In my essay I will talk about the skills required to get a good job nowadays. There will be three main points I will be discussing such as academic, personal management, and teamwork skills. I will give you examples of these skills, and reasons why this skill is important for you to get a job. Academic Skills   Ã‚  Ã‚  Ã‚  Ã‚  Academic skills are probably the most important skill you will need to get a job. It is one of the or the first thing an employer looks for in an employee. They are skills which give you the basic foundation to acquire, hold on to, and advance in a job, and to achieve the best results. Academic skills can be further divided into three sub-groups; communication, thinking, and learning skills.   Ã‚  Ã‚  Ã‚  Ã‚  Communicate. Communication skills require you to understand and speak the languages in which business is conducted. You must be a good listener, and be able to understand things easily. One of the most important communicating skills would be reading, you should be able to comprehend and use written materials including things such as graphs, charts, and displays. One of the newest things we can add to communicating skills would be the Internet, since it is so widely used all around the world - you should have a good understanding of what it is and how to use it.   Ã‚  Ã‚  Ã‚  Ã‚  Think. Thinking critically and acting logically to evaluate situations will get you far in your job. Thinking skills consists of things such as solving mathematical problems, using new technology, instruments, tools, and information systems effectively. Some examples of these would be technology, physical science, the arts, skilled trades, social science, and much more.   Ã‚  Ã‚  Ã‚  Ã‚  Learn. Learning is very important for any job. For example, if your company, gets some new software, you must be able to learn how to use it, quickly and effectively after a few tutorials. You must continue doing this for the rest of your career. It is one thing that will always be useful in any situation, not just jobs. Personal Management Skills   Ã‚  Ã‚  Ã‚  Ã‚  Personal management skills is the combination of attitudes, skills, and behaviors required to get, keep, and progress on a job and to achieve the best results. Personal management skills can be further divided into three sub- groups just as academic skills, which are positive attitudes and behaviors, responsibility, and adaptability.   Ã‚  Ã‚  Ã‚  Ã‚  Positive Attitudes And Behaviors. This is also very important to keep a job. You must have good self-esteem and confidence in yourself. You must be honest, have integrity, and personal ethnics. You must show your employer you are happy at what you are doing and have positive attitudes toward learning,

Bystanders need to make a change and take action Essay

â€Å"You can`t wake person who is pretending to be asleep†-Navajo Proverb People act as if nothing is happening when they do not want to face the reality of the situation by pretending to be unaware or unsure despite being presented with the evidence. Many people now a days, perform actions which may seem like they are participating in an activity but in reality they are just watching. People do not focus on the situation itself, but they focus on their surroundings. They understand that they might be in a difficult position although they try to avoid it. Some situations where humans experience themselves being in one place physically and having themselves in a different spot mentally are when people are being bystanders. Bystanders are people who are present in an event or incident but do not participate or act upon it. Bystanders have always been a part of the world’s natural occurrences. The bystander effect has occurred in history intensively up to this period of t ime. The bystander effect has been present in the Holocaust, the Partition of India and Pakistan and Barack Obama being appointed as the first African-American president. The bystander effect occurred all the way back to the 1900’s, during the time of World War 2. There was a destructive event that took place, it was called The Holocaust. The Holocaust was a great devastation sacrifice completed with fire. It was systematic mass slaughter of European Jews by the Nazi government and advocators. During this period of time, 6 million lives were taken. They were at their most efficient from April to November 1942 – 250 days in 2 which they murdered two and a half million Jews (http://www.facinghistory.org).. The governments of the United States, Britain, and the Soviet Union even made a joint statement acknowledging the mass murders for the first time. Yet, they continued to do nothing to stop or prevent more innocent deaths (http://www.facinghistory.org). The allied nations were aware of the deaths of the millions of innocent Jews but being informed about the scenario they continued to avoid the situation. Being people with higher authorities, the allied nations could have prevented or stopped this disaster from taking place. But they did not want to get themselves into a problem and create conflicts for their own countries. They were afraid that if they did not support the bully, they would be the next  victim. As innocent people were getting murdered in Germany, in India near that same period of time innocent people were being raped. In August 1947, the partition of British India took place. This event was life altering for millions of people. After the British parted from India, the creation of two countries raised India and Pakistan. This catastrophe was known for the abduction, rape and abuse towards women. In 1950, Menon and Bhasin wrote, the â€Å"official estimate† for numbers of abducted women stood at 50,000 Muslims in India and 33,000 Hindus and Sikhs in Pakistan (http://www.womenundersiegeproject.org). Women of different ethnicities, age and social classes were all victimized, raped and tormented. The men would also publicly molest the women to make them feel traumatized and disgraced, and people would just watch the awful sin like it is casual and not do anything to stop what is happening. The stories of these abductions and rapes caused panic; in many rural areas familie s reportedly killed their female children to save them from being defiled. Patel recounts numerous incidents of beheading, drowning, burning, and execution by the male head of family in order to â€Å"protect his women†Ã‚  from the threat of dishonour (http://www.womenundersiegeproject.org). People would just stand around and watch men rape women. But nobody did anything, they just stood and patrolled. They watched and encouraged, because she was the opposite religion, she was the enemy. People were discriminated based on their race, culture and religion and currently are being victimized for the same reason. On November 8, 2008 Barack Hussein Obama was elected the 44th president of the United States. This victory introduced many hardships into Obama`s life in views of him being the first ever African-American president of the United States. Because this was a racial alteration in many people’s lives, he was verbally and emotionally attacked with racial violations. Obama has also dodged numerous racist attacks from conservative protestors and personalities. Last year, a group sang â€Å"Bye Bye Blackbird† and waved signs reading â€Å"47 percent Negro† and â€Å"Impeach the half-white Muslim† at one of his speaking events (http://www.usnews.com). In this scenario, there was persistent name calling related to colour, ethnicity, culture or faith. There were many points where hurtful behaviours, both physical and  psychological, made them feel unwelcome, powerless or worthless because of their colour, ethnicity, culture or faith. There were malicious messages and letters sent to Obama and people just continued and joined the others. They thought that since he is the first African American president in the United States, he should not deserve the same equality of right as the pervious white presidents. People trended by making fun of him, and no one did anything to stop it and it still continues to present days. There are many occurrences in life, when people just stand around and observe a situation but do not do anything to stop it, they do not act upon it. The human species is aware that  if they do not stop such catastrophes; they will give others a chance to have a negative perspective on other cultures, ethnicities, and races. Not making this okay, because it will cause many riots in the future. It is time,that bystanders start to make a change and take action for the right thing.

Advantages and Disadvantages of the Internet

The Internet seems to be one of the greatest wonders of the modern world. Nowadays, it is hard to find a house with no access to the Internet and every day, more and more people are discovering the amazing possibilities which it gives us. The Internet is the biggest and the most effective provider of the variety of resources and services. It is a worldwide database of any information you may need. However, information is not the only thing you can obtain thanks to the Internet.The World Wide Web also provides you with the access to a wide range of computer programs, games or the possibility to download your favourite music or films. What is more, the Internet facilitates your contacts with other people. Not only can you easily and quickly contact them via emails but you can also speak to them, thanks to the Internet communications program. They have become very popular recently as they enable you to make new friends on-line.However, the paradox is that while they facilitate your comm unication with others, at the same time they cause the deterioration of your contacts and relationships since it is much easier to stay at home and talk to somebody on the Internet instead of going out and socializing. Moreover, on-line friendships can turn out dangerous as you can never be sure who the other person is. In addition, the Internet is very addictive.People never notice that they spend too much time in front of the computer screen and that they use the Internet more often than they really need. Surfing on the net becomes more important than meeting with friends or going to the classes at the university and the reality they start to live in is the virtual reality. Another important advantage of the Internet is that it has become the most easily accessible and the best resource collection. It is used for the research purposes not only by the university students but also by the children from primary schools as more

SCADA Worm Case Study Example | Topics and Well Written Essays - 1250 words

SCADA Worm - Case Study Example It is as well the first worm which encompasses a programmable logic controller (PLC) root kit. Additionally, in the beginning Stuxnet worm dispersed without rhyme or reason; however, it incorporated a high level and sophisticated malware payload that was particularly designed to target Siemens supervisory control and data acquisition (or simply SCADA) systems that are intended to manage and observe detailed industrial procedures. In this scenario, Stuxnet infects PLCs by weakening the Step-7 software system that is employed to reprogram these systems (O'Murchu, 2012; Keizer, 2009; John, 2010; Masood, Um-e-Ghazia, & Anwar, 2011). This paper discusses the impact and the vulnerability of the SCADA/Stuxnet Worm in the critical infrastructure of the United States. This paper will also discuss some of the important methods to mitigate the vulnerabilities. This research will investigate the levels of responsibility between government agencies and the private sector for mitigating threats an d vulnerabilities. Vulnerability of the SCADA This section outlines some of the major vulnerabilities regarding SCADA. Various research studies have shown that a range of vulnerabilities still exist inside SCADA systems. In this scenario, the majority of extensively publicized security based attacks on SCADA systems have taken place over the past few years as well as a large number of reports have been produced confidentially and publicly admitting issues and challenges securing similar systems. For example, SCADA system’s major vulnerability revealed itself when Japanese groups purportedly attacked control systems organizing commuter trains. Another major vulnerability attack was the Slammer worm that immobilized a security monitoring arrangement at Davis-Besse nuclear power plant located in the Oak Harbor, Ohio in the year 2003 (Swan, 2012; Fidler, 2011; Rebane, 2011). In addition, there are so many other instances of this attack, for instance a major vulnerability taking p lace due to an illegal intrusion through a previous, disgruntled worker into a worldwide chemical corporation attempting to cause damage. In the same way, Ira Winkler’s security based vulnerability instance in SCADA happened while conducting experiments at a power corporation network that was so flourishing that the test had to be stopped. Another major vulnerability in SCADA was identified due to the Sobig computer virus that influenced the CSX train signaling arrangement in the year 2003. Additionally, the disruption in collaboration and communication happened in Worcester, Massachusetts Air Traffic Communications system in 1997. SCADA vulnerability also happened due to foreign actors, where a cyber attacked a United States water plant in an obvious effort to achieve access as well as probably control of the significant corporate arrangement. In addition, the latest Stuxnet Worm that spreads extensively searching for exact SCADA applications and systems, supposedly attackin g Iran’s Natanz nuclear arrangement, allegedly reasoning 1,000 centrifuges to spin out of control (Swan, 2012; Fidler, 2011; Rebane, 2011). Moreover, these above stated different vulnerabilities could have taken place due to some of the reasons (Swan, 2012; Fidl

Religions Influencing the Policy Research Paper

Religions Influencing the Policy - Research Paper Example Though it has been assumed to play major roles in peace making around the world, divisions and battles have taken place in the name of religion. Over decades, religion has diversified and developed to include major religions like Christianity, Islam and Judaism. Christianity and Islam are the two major religions that have contributed to economic, social, political and cultural development in world societies. Christianity has over two billion followers throughout the world; God being the Supreme Being then there is Jesus the son of god believed to have died to save Christians from their sins and the Holy Spirit. Christians read the bible and believe in its teachings taught by pastors and priests across the world. Christianity describes the way of life, the reason for existence and the plans for the future nourished by the Holy Spirit. Christians believe that they should not have anything to do with politics instead they should simply preach the gospel. They insist that Christ died for our sins and rose on the third day but that does not make it a geographical or a social entity for violence or political gains (Livingston page 8). But this does not mean that Gods kingdom has nothing to do with the world or that politics are not important, it simply means that the gospel should not be reference for political violations. What Christians should strive for is how the politics will have impacts in their lives and how it can affect their belief in Jesus Christ and the church. It is believed that every Christian is a soldier of the Lord and there are Christians who entangle themselves with politics in the belief that God will not object. There is nothing wrong with fighting injustice or wanting things to be done differently because that’s part of expressing opinion but politics is not an easy way to take for Christians. There will always be question of why a Christians joins politics; their motives are they for fame, money, power or truly taking the seat to serve the people. Politics offers are promising and at times purity motives may be hard to sustain as one will be devoting more money, energy and time on politics than Christianity which encourages one to take on humble ways. Christians believe that you cannot eliminate wickedness by laws or legislation instead the easiest way which is also approved by God is through salvation and forgiveness of sins through his son Jesus. In the bible we see that God established government, but not political sciences that come up with new laws, better laws meant to make the world a better place or try to take advantage of the less elite. Government was meant to give people a leader who ensured that everyone lived according to God’s will and teachings (Livingston page 7). Politics cannot make a better world for humans to live in it or save souls but God can do both. The bible encourages people to follow and even obey the laws put across but it never gives a go ahead for Christians to be involved w ith politics. This is because Christianity is a big role the same goes for politics and keeping the balance between the two can be overwhelming. Keeping up with the two lives is nearly impossible that’s why Christians are encouraged to stick to their faith and practice the will of God which is spreading the gospel. Islam Islam has more than a billion followers who worship Allah, have Muhammad as their latest prophet and believe in angels. Muslims are the followers of Islam who are devoted to Koran and its teachings. Muslims unlike the Christians are required to know all the teachings of the Koran by the time they are a certain age. Though Islam religion is strict and disciplined in its customs and rules, its

Climate Change Research Paper Example | Topics and Well Written Essays - 1750 words

Climate Change - Research Paper Example It cannot be denied that GLOBAL WARMING was under consideration by almost every country and different measures are been taken to prevent but it is required on a very large scale with a contribution of every individual living in. It can be done in a lot of ways for example promote plantation, avoid using plastic products as it a non-biodegradable item and a main source of pollution, energy conservation, recycling of goods, preservation of natural resources, and banning the burning of fossil fuels which contributes highly in the destruction of the ozone layer which works as an umbrella or a shelter from strong sun radiations affecting the globe directly .All these factors are causing Global Warming which works as a driving force for the fluctuations in Climatic System. Climatic change does not only affect the nature but majorly affects the living beings. Whereas, drastic changes are coming up because of the activities done by the masses for worldly pleasures for which natural resources are continuously been misused and immeasurably been wasted. There are some major changes in the climatic system which occurs because of the rise in temperatures of the living world. Human Influences is directly propostional to the global warming. Following are Sub-reasons for the change in climate cycle: Orbital Variations Solar Output Volcanism Ocean Variability Plate Tectonics These are the regions where fluctuations occurs and affect the globe and each will be discussed thoroughly further in this report. It is recorded previously in surveys that Climatic Changes are affecting adversely on Biodiversity. This is alarming for the species which are already left with a handful numbers like Polar Bears, Indus Dolphins and many more. They are getting affected because of the change in eco-system occurring because of the changes in the earth’s crust. As the global temperature rises, it starts throwing off to cool down. Volcanic Eruptions is one of the cooling processes, when done with the eruption, the temperature of the globe drops down to 0.5 degrees. Same is the case is with Earthquakes and Ocean Variability. Footnote: (Wikipedia, the free encyclopedia) Historical and Archeological Evidences: It is studied in the continuous research being done in this aspect and different historical and archeological evidences are pouring in that how the climate used to be in a particular region and how it has become after several years. Civilization changes also predict to a certain level of how the climate probably was. According to archeological evidences, researchers have put their efforts on different areas of life through which they might get to the key. Some of the under consideration areas of life which can predict or can give a clue to the present world that climatic cycle have changed to what extent and whether good or bad. The following are: Glacier changes: Glaciers are the most sensitive indicator of the climate change because of its immediate reaction to any changes in the temperature. There are two things which can contribute in the shrinkage and growth of the glaciers, they are orbital variability and external forcing. Evidences are found because glaciers leaves moraines that contain an anonymous amount of material including organic matter

Data Analyzing Tools And Techniques - Essay Example These statistical presentations are unable to draw out in-depth coverage of the actual information even after the allocation of huge investment in data analysis. Consequently, alternative devices are being taken into serious consideration to transferring the knowledge along with a statistical presentation of the entire data. The present study presents the model that successfully presents the model that accepts the challenge of transferring the data to knowledge and results in a comprehensive and refined way by encompassing every characteristic of the given information separately. It neither drops any information from an analysis nor does it conceals basic knowledge the actual data intends to communicate; hence, it is of great value for taking steps towards right direction while taking decisions and devising strategies at different organizational levels at large. Policymaking always relies upon accurate facts in recruitment, placement, promotions and even dismissal of employees; it is equally significant for examining of corporate culture, profit rate and visits and satisfaction scales of the customers regarding a particular organization as well. The model is based upon five key competencies including software technology skills, statistical modeling and analytic skills, knowledge of the data, knowledge of the business and communication/partnering skills, all of which are essential for data analysis. Since over three-fifths of the managerial staff views organizational and cultural factors as the greatest barriers to achieving targets, the model provides the all-inclusive presentation about organizational culture too. Particularly, data related to sales volume is most important for managerial staff, comprehensive and analytical record of which is essential for future business plans in technological, transformational and analytic processes.

What is Hajj Essay Example for Free

What is Hajj Essay Hajj is one of the five Islamic pillars. It is where all capable Muslims must go on a pilgrimage at least once in a lifetime to Makkah in the last month of the Islamic year. These months are Muharram, Safar, Rabi al-Awal, Rabi al-Thani, Jumad al- Ula, Jumad al-Thani, Rajab, Shabaan, Ramadaan (Month for Daily Obligatory Fasts), Shawwaal, Dhul- Qidah and Dhul- Hijjah (the month for Hajj). And Hajj (pilgrimmage to Makkah) to the House (Ka`abah) is a duty that mankind owes to Allah, those who can afford the expenes (for ones conveyance, provision, and residence) Al-Quran:Surah 3 (Al-Imran); Verse 97 Hajj is the name given to the journey made by Muslims to the Kabba at Makka in Arabia. It is a very large, spiritual gathering and they arrive in very large numbers, sometimes up to 340 a minute. Women wear a burka (a long cloth covering from the head to the feet) men wear a sort of tunic for hajj. When they arrive at Makka the first thing they do is bathe and put white sheets on to enter purity (Ihram). They then go to a sacred mosque to start prayers; they repeat the Talbiya over and over again (translated into English): Here I am O Allah, Here I am Here I am. There is no partner with you. Here I am. Verily, Thine is the praise, the blessings and the sovereignty of the Universe Thou has no partner They then run between two hills to represent what happened when Hajar did this to find water for her son Ishmal. They come to the spring (Zam Zam), which Allah found and people desperately try to drink and bathe in the water which comes from it. This is a Muslims search for spiritually. After this they walk 7 times around the Ka`aba (black stone), this symbolizes when 630 people rode into Makka and destroyed all Idols and Allah forgave the citizens. The first night of the Hajj is spent at Mina. The second day is spent at Arafat; this is where the prophet Muhammad gave his farewell speech, it is desert location approximately 9 miles from Makka. Muslims say this prayer upon entering Arafat so that Allah forgives their sins: O Allah! Forgive my sins, help me repent to you, and grant me all that I beseech of You. Whenever I turn, let me see goodness. Allah be praised! All Praise is due to Allah! There is no deity except Allah! And Allah is The Most Great. The Muslims collect small stones for the following day. Day three is spent at Mina; this is where the Muslims stone the devils (Jamrahs). 7 stones are thrown at each of the 3 pillars; they do this because the devils tempted Ibraham to disobey Allah three times, it shows that they are against anything devilish. Weak and sick people can appoint others to throw stones at the Jamrahs in Mina on behalf of them. Tawaf al-Wada is the farewell Tawaf that a pilgrim performs just before leaving Makka for other destinations. It is the same as before when they go around the black stone in 7 circuits, starting from the black stone line. After completing the Tawaf, it is good but not required to pray too Rakahs behind Maqam Ibrahim. This day is the sacrifice day where they sacrifice an animal (Eid-ul Adha); they are supposed to sacrifice goats, sheep, rams, camels or cows. This act is performed to commemorate Prophet Abrahams act of sacrificing his oldest son Prophet Ismaeel on the command of Allah. Allah substituted Prophet Ismaeel with a ram. Muslims are required to donate 1/3 rd of the meat to the poor, distribute 1/3 rd of the meat to friends and relatives, and keep 1/3 rd of the meat for themselves. Men shave their heads and women cut off locks of hair. After this they return to Makka again to do 7 more circuits of the Ka`aba. Muslims take part in the Hajj because they believe that it is their duty to go, so that Allah will respect them and they will live in paradise when they die. Even if they cannot go for any reason they believe that having the right attitude about going will be acceptable to Allah. It provides an opportunity for Muslims with diverse racial, ethnic and geographical heritage to exchange views, get acquainted and feel unified as one Ummah (community) on a global level. They also go because they enjoy the spiritual gathering, they are happy and they like being around other Muslims who share the same beliefs as they do. Not all Muslims go to Hajj however, as there are certain difficulties effecting whether or not they can go. Some people cannot afford to go but would do if they have the money, if they still have the intention to go (Niyyah) this would still be acceptable to Allah. They can send one person to represent a whole community, which is also accepted. As Hajj is so popular (over 2 million people go each year) they have to limit the numbers of people who go, this means that not everyone who wants to go can, so this is again another difficulty Muslims have. People also have difficulties attending Hajj because they have disabilities or they are unable to walk etc. For example and old person who is frail may not be able to cope with the heat and walking/travelling far. People who are ill and have ill health may also not be able to attend Hajj, as they may be bed-ridden etc. If people cannot attend Hajj for various reasons but have intention (Niyyah) to go, it is still acceptable to Allah. Participating in Hajj affects the life of a believer because they come alive spiritually. It is important for them to go and they feel love from Allah while they are there. They enjoy going, to be around other Muslims. When they return they feel closest to God as they stood on the site where the Prophet delivered his sermon during his first and last pilgrimage. They go back full of joy as they have for filled Allahs wish. They also return with a better understanding of Allah and a born a spirit of caring for others and an understanding of their own heritage that will last throughout their lives. A true pilgrimage is really a journey within. It is important to physically go to Makka but if it is not possible to go I believe that you can still participate spiritually. I believe that if it is in your heart to go this should be accepted as you can still enjoy Hajj without going. You can use technology to participate in Hajj, for example you could pray while watching the festival on television or look at a video of the gathering on the Internet. You could also have your own party at home with other Muslims who do not go to Makka and celebrate Hajj and the end of Hajj (Eid ulad ha) together. Just because you do not go to Makka does not mean you do not follow Allah, you can still participate in Hajj without physically being there. So people who cannot go for various reasons such as old age etc can still enjoy the celebrations and not be cast out of them for being different. If I were a Muslim I may have a different view on this subject because they believe that if it is physically possible to go, you should go no mater what, as Allah would want you to. They feel that it is a religious duty to go, as it is one of the five pillars. A Muslim would go because they want to please their God, Allah.
