Money and banking Research Paper Example | Topics and Well Written Essays - 1000 words
Money and banking - Research Paper Example Despite the governmentââ¬â¢s efforts to prevent the collapse of the banking system, it did not successfully restore economic growth; the United States entered a deep recession in December 2007 that extended up to June 2009 (Kroszner and Melick 6). FED used the three tools of monetary control: open market operation, reserve requirement, and discount rate to counteract the progression of the financial crisis. Figure 1: The Graph showing the financial crisis between 2007 and 2007 (Source: Gowland 33) The graph above shows that there was constant recession between 2007 and 2009. Financial recovery began to be experienced as from march 2009. Open market operation The most appropriate monetary policy that was used to counter the financial crisis of 2007-2009 constituted the increase the monetary base. Open market operation (OMO) is an instrument of monetary policy, which involves selling and purchasing of marketable securities (Stock and Mark 11). These transactions are conducted in the open market by the central bank as an instrument of controlling the monetary system. Open market operations target the cash balances of held by commercial banks and other non-bank financial institutions including their tills and in relation to their excess reserves at the central bank. The central bank sells its holdings of the government securities to commercial banks to reduce excess reserve held by commercial banks. When the central bank anticipates liquidity deficiency, it injects additional liquidity by purchasing from the existing stock of the government securities. Decreasing the monetary base during the 2007-2009 financial crisis involved the reduced supply of credit, which was used to facilitate the adjustments in financial market in order to achieve equilibrium in money demand and supply. The Federal Reserve had to sell large quantities of securities that were necessary to achieve decreased supply of credit (Stock and Mark 22). Fed would also sold high-quality securities to minimize Fedââ¬â¢s credit risk and the public would be informed that the expansion in the monetary base is temporary; thus, the composition of Federal Reserveââ¬â¢s balance sheet and size of the monetary base would be restored to normal after financial markets and economic activity begin to normalize. The Federal Reserve used the tool of open market operations with an objective of supporting proper functioning of credit markets, reduce the pressure on long-term financial markets and make financial conditions accommodative by selling long-term securities for the Fedââ¬â¢s portfolio. Figure 2: The Open Market Operations Graph (Source: Stock and Mark 21) i represents the nominal rate of interest, Dm represents money demanded and Ds represents the money supplied. The Federal Reserve varies the rates of interest to ensure maintenance of demand and supply of money with the aim of preventing financial crises. Discount Rate The second tool of monetary control that Fed used durin g the financial crisis is the discount rate. Under this policy, the bank can borrow reserves from the Federal Reserve at their discount windows (Stock and Mark 18). These rates are set by the Boards of Directors of the Reserve Banks, but the rates must be subjected to determination and review by the Federal Reserve Board. The Federal Rese

Of mice and men Essay Example for Free
Of mice and men Essay In the novel of mice and men many of the characters are lonely. They have no one that really cares for them. This could be because that individual is coloured, female or that the person doesnt fit in with anyone. One of the characters that are lonely in this novel is Characters such as crooks who are lonely because hes black (coloured). Crooks spend the vast majority of his time in the barn. The only way he can socialise with the other men is when theyre all playing horse shoes. Other times, hes not allowed in the bunk house. For example Lennie, candy and Crooks were talking in the barn house and Curleys wife came in and they all wanted her to go. Crooks stood his ground to her as they were all arguing. He said You got no rights comin in a coloured mans room. You got no rights messing around in here at all. Now you jus get out, an get out quick. If you dont, Im gonna ast the boss not to ever let you come in the barn no more. Curleys wife replied with Listen nigger, you know what I can do to you if you open your trap. The book then reads Crooks seemed to grow small, and he pressed himself against the wall. Yes, maam. What Curleys wife meant by saying what she could do to crooks is that all she has to say to Curley or anyone, is that Crooks has been coming on to her and harassing her. Once she has said that, Curley will be after Crooks and beat him. No one will want to listen to Crooks side of the story simply because hes black (coloured). Other characters in the novel such as Curleys wife are also lonely. John Steinback purposely didnt give Curleys wife a name because it shows that she was not treated as a normal human being. In the novel Candy has his dog that is simply known as Candys dog. This is shown of what Curleys wife means to everyone in the novel. All that she was to everyone was Curleys property or owner. An example is in chapter three was, Did you see that girl? You mean Curleys girl? Like crooks, Curleys wife does not have a say in anything. In the novel Lennie is another character who is also lonely. He is mentally ill, and has the mind of a child who is five years old. He imitates quite often what George is doing, just like a child would do to someone else for example, He pulled his hat down a little more over his eyes, the way Georges was. He also has the tendency to forget things that he has been told, and is quite often called a crazy bastard by George. For example, So you forgot awready, did you? I gotta tell you again, do I? Jesus Christ, youre a crazy bastard. Like Crooks, And Curleys wife, Lennie cant go out with the other men, such as when the whole group went into town Lennie had to stay behind with Crooks. He can not do this because he cant be trusted with meeting strangers, such as like what happened in Weed when he supposedly raped that little girl. What really happened was that he just wanted to feel the girls dress because he likes to feel soft and furry materials, and he panicked and the only thing he could do was to hold on until George had to sock him. Lennie also is Lonely because he does not have the choice to do what he wants, George has to give him instructions and tell him whats right and whats wrong. At the near beginning of the novel Lennie wanted to keep a dead mouse which he said he had found dead, however George told him to give the mouse over to him and Lennie, (who loves to pet mice and furry things) and Lennie handed the mouse over to George and obeyed him. Its only a mouse George A mouse? A live mouse? Uh-uh. Jus a dead mouse, George. I didnt kill it. Honest I found it. I found it dead. Give it here, said George. Aw, leave me have it, George. Give it here! Lennies closed hand slowly obeyed. Lennie is also a tall built man who isnt aware of his own strengths. He likes to pet mice but always kills them because he doesnt know his own strength. E. g. They was so little, he said apologetically. Id pet em, and pretty soon they bit my fingers and I pinched their heads a little and they was dead. Lennie has also often been compared to animals in the novel. All these things about Lennie like being a bit dumb, being forgetful or just being childish are what I think make him so lonely in the novel. He is nothing like anyone else, he doesnt ever want to cause trouble but he does it all the time without knowing what hes getting himself into and because of that he can not socialise with many other people which I believe is resulting in his loneliness in the novel. Another character in the novel of mice and men who is lonely is Candy. Candy only has his dog to keep him company, and was very sad to see the dog go after he was shot due to his bad smell. Candy has only his dog and has always been devoted to it. When he was told to shoot the dog he looked at it for a while and replied. No, he said softly. No, I couldnt do that. I had Im too long. Not only does Candy require his dog for companionship but the dog needs Candy for basic survival, the dog obeys Candy. E. g. Come on boy. Come on, boy,he said gently. The old dog slowly and stiffly to his feet and followed the gently pulling leash. Even though the dog has been physically damaged, Candy still wants to stay with it and keep it. Ill put the old devil out of his misery right now and get it over with. Aint nothing left for him. Cant eat, cant see, cant even walk without hurtin. Candy even didnt except another little pup from slim because he loved that dog so much. So despite the dog being physically damaged and not being able to do anything, Candy needs the dog because its the only thing he has got and he loves it and has really gotten use to it. He was left feeling lonely after it was shot.

Human Adaptations to Extreme Cold
Human Adaptations to Extreme Cold à Abstract Humans have successfully adapted to environmental stresses, including extreme cold. A review of existing literature examining archaeological data, historical data, and current populations regarding human adaptation to cold stress (average annual temperature of ~ -14à °C / 7à °F) yields evidence supporting distinctive morphological, physiological and behavioral traits that compensate for the stress. Morphological adaptations can be seen in elongated and narrowed nasal passages (long narrow noses), which help warm and hydrate the air before it passes into the lungs; and a decreased surface area to volume ratio and allowing the individuals to more easily maintain a normal core body temperature. Physiological adaptations include: increased basal metabolic rate, which increases the amount of body heat produced; and a higher prevalence of type 1 diabetes, which may be a genetic adaptation that protects cells from freezing. Additionally behavioral adaptations can be observed in agricultur e, awareness of fickle environmental factors, and clothing. Traditional populations in sub-polar regions tend to be hunter foragers; agriculture is limited to what can be cultivated in the short growing season. Some populations demonstrate acute awareness of weather patterns, modifying their behaviors to minimize exposure to dangerous conditions while taking full advantage of more temperate periods. The author finds ample evidence of widely varied human adaptations to extremely cold environments which allow sub-arctic populations to survive more easily in their specific environments. Human Adaptations to Extreme Cold Humans have successfully adapted morphologically, physiologically, and behaviorally to environmental stress, including extreme cold. As a species, humans have survived Ice Ages which brought the intensely cold environment, normal for our polar and sub-polar regions, across much of the planet. To understand the wide variety of adaptations which have proven successful, the author explored existing literature analyzing data from archaeological, historical, and anecdotal sources, as well as from current populations. Because more information involving human populations exists for inhabitants of sub-polar regions than for any other extremely cold environments (except high-altitude locales where oxygen level is a significant contributing factor for adaptation and would complicate conclusions which might be drawn about adaptations to cold stress) the author focused there. Extreme cold is defined, in terms of environment, by examining monthly mean temperature charts provided online by the U.S . Navy (Guest, 2000). These data show that monthly mean temperatures at sub-polar locations, both north and south, range from -30à °C (-22à °F) in January to +5à ° C (+41à °F) in July, with daily variations from -40à °C (-40à °F) to +30à °C (+86à °F) yielding average annual temperatures ~ -14à °C (7à °F). Ample evidence exists to support conclusions that morphological, physiological, and behavioral adaptations have occurred in response to the stress of existence in extremely cold environments. Morphological adaptations can be seen in elongated and narrowed nasal passages, broad pelves, and relatively short, stocky bodies. (Kennedy 2007; Hernandez, Fox, Garcia-Moro 1997). Fueguians and the Eskimos are the human groups with the narrowest and highest nasal apertures, displaying a combination of large nasal height and low nasal breadth values, while groups from equatorial areas have low, wide nasal passages (Hernà ¡, et al. 1997). Both groups lived and/or live in the sub-polar regions (one nearer the southern pole, one nearer the northern). Fueguians inhabited Tierra del Fuego, the southernmost tip of South American after the ice sheets receded, ~ 10,000 to 12,000 BP (before present). Unlike the sub-Arctic environment, which is cold and dry, the climate of Tierra del Fuego is extremely cold, rainy, foggy, and windy. Average temperatures are in line with our definition of extreme cold, but in addition the area receives ~3000 mm (118 in) of rain each year and strong, persistent winds that blow off the glaciers, inducing a significant windchill affect. (Hernà ¡, et al. 1997, and references therein) took craniometric (measurments of the skull) measurements of 180 skulls from three distinct tribal groups of the area and analyzed them in relation to Howells 28 craniometric series in order to increase the statistical significance of the sample. When all the measurements were plotted on a climate map, a strong correlation between increased nasal height combined with narrow breadth and extremely low temperatures is apparent. Researchers postulate that high, narrow nasal openings allow frigid air to be warmed by the mucous membranes lining the nasal cavity to prevent damage to delicate lung tissue, and enhance the recovery of heat and moisture from expired air. (Hernà ¡, et al. 1997) Another morphological adaptation supported by existing studies is a short, stocky body structure. Body proportions of humans [and other endothermic (i.e., warm-blooded) species] have long been known to show significant correlations with climatic variables and their proxies. Specifically, two empirically derived ecogeographical rules, those of Bergmann (1847) and Allen (1877), state that within a widespread endothermic species, those in colder regions will tend to weigh more (Bergmanns rule) and be characterized by shorter appendages (Allens rule) than their conspecifics [members of the same species] in warmer climes. (Holliday and Hilton, 2010 and references therein). They also put forward colder-climate groups being characterized by broader pelves, and reference C.B Ruffs work from the early 1990s. Holliday and Hilton (2010) examine skeletal data from the Point Hope Inuit (another name for Eskimo) of North America. A total of 173 individuals, 127 from the Tigara period (13th to 17th century AD) and 46 from the Ipiutak period (~100 BC to 500 AD) were measured and analyzed relative to other Native North Americans, and samples from Europe, North Africa, Sub-Saharan Africa (from similar periods). Based on results from previous studies referenced, Holliday and Hilton concentrated their effort on measurements which have already been determined to vary with climate, specifically limb bones from the four major limb segments, femoral head diameter, skeletal trunk height (the summed dorsal body heights of T1-L5 plus sacral ventral length), and bi-iliac breadth [pelvic width]. (Holliday and Hilton, 2010). From the basic measurements, the authors computed seven ratios which are identified as indices for comparison. Results show that African samples provide the lowest indices while circumpolar populations show the highest, with European numbers in the middle. Neither of the groups measured specifically for this study (nor the third Native North American sample) is signific antly different from the other, but marked variations exist between these groups and both of the African groups. Interestingly, results do not support the authors expectation that the Inuit and Europeans would show a discernible variation using the specific indices studied. However, the bi-iliac relative breadth index (pelvic breadth compared to assumed trunk height) did separate these two groups distinctly. As a counter-point, it is noted that there are other factors which can affect overall stature, such as under-nutrition. In a harsh environment, maintaining sufficient nutritional intake is likely compromised, and so the shorter body may not be simply an adaptation to the extremely cold environment. Popular rhetoric holds that a layer of body fat helps keep humans, and other mammals, warm. In his 2007 American Journal of Human Biology article, Human cold adaptation: An unfinished agenda Steegmann does not disagree; he says, Fat insulates better than muscle per unit of thickness. However, in a fit person, muscle layers are usually much thicker than subcutaneous fat and consequently have higher absolute insulative value. Studies in the 1950s and 1960s (referenced in Elsner (1963): LeBlanc, 1954; Baker and Daniels, 1956; Daniels, et al, 1961) demonstrated that Caucasians with a thicker layer of body fat, as measured by skinfold, maintained core temperature, skin temperature, and metabolic rate more reliably when exposed to 15à ° C (59à °F) for two hours. However, in a similar study (Elsner, 1963) compared the skinfold thickness of eight hunter-gatherer groups (aborigines of central and northern Australia, Inuit of Canada, Eskimos, Alacaluf Indians of southern Chile, Lapps, Peruvi an Indians, and Kalahari bushmen), and cold-acclimatized Norwegian students, with urban Caucasians as a control. Skinfold thickness was measured at ten locations: abdomen, back (subscapular), calf, cheek, chin, iliac crest, knee, pectoral, upper arm,and side. The urban Caucasian control group had higher values across the board, except for the cheek measurement. Of particular interest, Canadian Inuit, and Eskimos had amongst the lowest values; not what was expected from populations that acquire 70-75% of their caloric intake (see above) from animal fat. Additionally he measured the rectal temperature, metabolic rate, and skin temperature of his subjects during an eight-hour sleep period with ambient room temperature of 0à ° 5à °C (32à ° 41à °F) during which time they had only one thin blanket to wrap up in. Elsner reports that there was poor correlation between skinfold thickness and the measurements of interest during the overnight study. In support of these findings, from ano ther study, Steegman (2007) reports results which demonstrate that Inuit traditionally had high muscle mass and high work capacity, but low body fat. Aside from the subjective observation that the primitive groups had better sleep than the control group, three sets of reactions emerged from Elsners study: 1) Canadian Inuit, Eskimos, and Alacaluf Indians, and cold-acclimatized Norwegian students demonstrated high metabolic rates (measurement technique not defined) and warm extremities; 2) Kalahari bushmen and aborigines from central Australia had stable or falling metabolic rate and cooler skin; and 3) Peruvian Indians and Lapps had low rectal temperatures and higher extremity temperatures. So, while a thicker layer of body fat does not seem to be a human adaptation for survival in extremely cold environments, increased metabolic rate and some protective mechanism to keep extremities warm both appear likely. (Makinen, 2007) Physiological adaptations include: increased basal metabolic rate, high protein/high fat/low carbohydrate nutritional requirements, and some evidence of variations in blood chemistry. (Westerterp-Plantenga 1999; Srivastava, Kumar 1991; Moalem, Storey, Percy, Peros, Perl 2004) An inverse relationship between BMR and mean annual temperature has been documented, which holds true even when controlled for differences in body size. (Snodgrass, et all 2005) In fact, Snodgrass, et al (2005) conducted extensive research among the Yakut population in Siberia (sub-polar Asia) which supports the claim that increased basal metabolic rate is an important human adapation to the stress of an extremely cold environment. With a thorough and well-documented scientific process, participants in the Snodgrass study underwent measurements of core temperature, oxygen consumption, carbon dioxide production, and heart rate in a thermoneutral (23à ° 27à °C) environment after a 12-hour fast. Results for basal metabolic rate (BMR) were predicted based on three standards drawn from a European population: fat-free mass (FFM), surface area (SA), and body mass. In all three cases, for males and females, the Yakut BMR measured significantly higher than predicted values. The BMR of Yaku t men and women were demonstrably elevated over their more southern-dwelling, European counterparts. Another metabolic adaptation might be seen in the increased incidence of Type 1 diabetes mellitus among northern Europeans. Moalem, et al (2004) Recent animal research has uncovered the importance of the generation of elevated levels of glucose, glycerol and other sugar derivatives as a physiological means for cold adaptation. High concentrations of these substances depress the freezing point of body fluids and prevent the formation of ice crystals in cells through supercooling, thus acting as a cryoprotectant or antifreeze for vital organs as well as in their muscle tissue. Citing the example of cystic fibrosis conferring immunity to typhoid (salmonella typhi), the authors suggest that elevated blood glucose levels, such as are seen when the body does not produce insulin, may be the result of genetic mutation which gave an evolutionary advantage to inhabitants of cold climates about 14,000 years ago when world-wide temperatures dropped dramatically. Life expectancies then were short, so genetic adaptations that enhanced survival would have favored changes in the short term. Now that our life expectancies have increased to 70+ years, we can observe that such changes might have been beneficial then, but currently are causing dangerous health issues within the aging population. Traditional dietary intake of these populations of cold-dwellers depends completely on what is available at any given time. In 2004 Patricia Cochran, a native Inuit Alaskan, wrote on the traditional diet for Discovermagizine.com. Our meat was seal and walrus, marine mammals that live in cold water and have lots of fat. We used seal oil for our cooking and as a dipping sauce for food. We had moose, caribou, and reindeer. We hunted ducks, geese, and little land birds like quail, called ptarmigan. We caught crab and lots of fish-salmon, whitefish, tomcod, pike, and char. Our fish were cooked, dried, smoked, or frozen. We ate frozen raw whitefish, sliced thin. The elders liked stinkfish, fish buried in seal bags or cans in the tundra and left to ferment. And fermented seal flipper, they liked that too. She reports that in the short summers the villagers would forage for roots, greens, and berries.. What the diet of the Far North illustrates, says Harold Draper, a biochemist and expert in Eskimo nutrition, is that there are no essential foods-only essential nutrients. And humans can get those nutrients from diverse and eye-opening sources. Inhabitants of extremely cold climates do not live to eat, they eat to live. The traditional Inuit diet, which seems to a Westerner to be sorely lacking in fruits and vegetables, which the U.S. government insists are necessary for wellness, supplies all they need to maintain health in their sub-polar climate. Vitamin C, which is a vital component for healthy connective tissue, is found in raw animal organs, raw kelp, and even muktuk, which is as rich in Vitamin C as orange juice, gram for gram.Fat-soluble vitamins A and D are metabolically mined from cold-water fish and mammal fats and livers. Not surprising, then, that the traditional Inuit diet comprised 90% of its caloric intake from meat and fish, 50-70% of its calories specifically from wild animal fat fat is the source of not only calories but also necessary nutrients. This traditional Inuit diet based wholly on what food is available from hunting, fishing and forage-harvesting might be a behavioral/cultural adaptation to the climate, while also encompassing metabolic/digestive adaptations. While morphological and physiological adaptations to environment take eons to manifest, some cultural and social adaptations may be apparent on a far shorter time scale. Steegmann (2007, and references therein) speaks about Richard K. Nelsons comparison of Kutchin natives of east-central Alaska to Eskimos, explaining Nelsons observation that Kutchin hunters keep moving if they lose their way, afraid if they stop they will sleep and freeze. Eskimo rest as needed and only move to stay warm. He also noted that Eskimo had a complex understanding of weather prediction and were better equipped to plan accordingly and keep themselves safe. In both cases, Eskimos seem to practice higher survival skills and both behaviors are strongly directed by cultural traditions. Two very different responses to the same stimuli in similar environments, with potentially diametrically opposed results: survival and death. Another surprising and non-intuitive variation in responses to the extreme cold of sub-polar life can be found in the clothing styles of arctic and some sub-arctic populations. According to Hernà ¡, et al. (1997) arctic inhabitants, such as the Inuit, wear clothing designed to protect them from the harsh cold, whereas the three Fuegian tribes they study, who lived at the southern tip of South America, are anecdotally described as almost naked throughout their lives. The Fuegian tribes are extinct, so no opportunities to explore their cultural adaptations to their extreme environment. Human adapation to the stress of an extremely cold environment, such as those of sub-polar regions, can be seen in morphological changes, physiological changes, and behavioral/cultural developments. Morphological changes include long, narrow nasal passages, to pre-warm icy air and protect fragile lung tissues and short, stocky body structure, which increases the body mass to surface area ratio, conserving body heat. Physiologically, increased basal metabolic rate is strongly supported as an adaptation, in a contemporary population, to the extremely cold climate of Siberia. An increased incidence of Type 1 diabetes in cold climates is suggested as a favorable mutation during the rapid onset of a mini Ice Age, but more studies would be needed to prove this as a lasting adaptation. Changes in metabolism and digestion in order to extract necessary nutrients from the limited food sources available in a sub-polar climate may be a physiological adaptation, but without studies to demonstrate a change in how the Inuit (or other sub-polar inhabitant) body processes food in order to extract necessary nutrients, it should be categorized as a behavioral/cultural adaptations. They eat to live, utilizing all food sources available. Other behavioral adaptations can be observed in a more precise weather awareness, perhaps, and clothing styles.

London After the Fire Essay -- British History, Annus Mirabilis
Depending on how you view life will influence how you feel about the city you live in. People who live an honest life and see the glass half full will be more hopeful about tragedies. People who do not live an honest life and see the glass half empty will be more disparaging during tragedies. An optimist will also look at tragedy as a time of rebuilding where a pessimist will look at the same tragedy as life as we know it over. In this essay I will describe the view of London from Dyden's Annus Mirabilis and Pepys' Diary, I will discuss what each excerpt have in common and what differs with regards to the representation of the Great Fire of 1666, I will display each author's attitude toward the city, the nation and its people and finally showcase which writer is more optimistic of the city's future. By the very first line in Annus Mirabilis you can see that the author viewed the city before the fire as a great city that has made a turn for the worst "Yet London, empress of the northern clime, By an high fate thou greatly didst expire" (2085, 1-2). Dryden felt the city had claimed too much fame and possibly too much sin. This poem is remnant of the story from the bible of Sodom and Gomorrah because those cities were destined to be destroyed by God for the people of the cities sinful nature. Dryden must have believed London needed to suffer the same fate, but instead of being completely destroyed and gone forever London is not entirely burned and is rebuilt better than it was before "Great as the world's, which at the death of time Must fall, and rise a nobler frame by fire" (2085, 3-4). Looking into how Pepys feels about London it is a bit more difficult to decipher because he is writing... ...d this will keep him from having the sky come crashing down if everything does not turn out as he believes it will. In this essay, I have described the view of London from Dyden's Annus Mirabilis and Pepys' Diary. I have also discussed what each excerpt has in common and what differs with regards to the representation of the Great Fire of 1666. I have depicted each author's attitude toward the city, the nation and its people and finally showcased Dryden as the more optimistic writer with regards to the city's future. Remembering to look at the positive side of things when there is a tragedy is sometimes what makes us resilient enough to rise out of the ashes and rebuild. Every place on earth experiences tragedy and it is not the tragedy that defines people, but it is the actions they take afterwards that stakes claim in who they really are.

How to Put Together a Desktop Computer Tower
As a teenager I was always fond of computer. I built my first desktop computer in 2009 when I was able to afford purchasing all the components myself. In March of 2012 my desktop had a power surge and short-circuited the motherboard, rendering the rest of the components useless. I tore apart the desktop tower and inspected all my components to see what would be reusable. The power supply, video card, CD optical drive, and hard drive could all be salvaged. I placed all the salvaged components in an anti-static bag and stored them in a dry and relatively cool area in my closet.Once I knew what components and new hardware I would need I began researching all the new products in the market. I realized my once top of the line components were outdated but, being poor I had to make due with my salvaged parts. The list of components needed was concise, but rather expensive. I needed a new motherboard, central processing unit, processor cooler, and a new desktop computer tower case. I had to wait and save another paycheck to buy all the necessary components. As soon as all my components arrived I cleared approximately a five by five foot flat surface in my living room and laid all my components down in their boxes.I first unboxed my tower case and read the manual of its capabilities and how its fans are set up. I then opened all the rest of the boxes and laid out each component. Inspection of each component is a must at this point. If youââ¬â¢re able to find damage before you put your computer together itââ¬â¢ll save you the time of disassembling your computer once youââ¬â¢ve found out something has malfunctioned. If youââ¬â¢re lucky like I was you will not have any damaged parts and you can continue to assemble your computer rig. The first step to assembling the computer is to install your central processing unit.In my case, I had to install both the central processing unit and the processor cooler on the motherboard before mounting it in the tower case. On ce that was installed I proceeded to installation of the video card. On the motherboard there is a specific PCI-express x16 slot made for fast reading components such as the video card. Some video cards require two slots for the supplied cooling fan, as the more graphically demanding the software you run on your computer will be, the hotter your video card will run. After the video card was installed I then installed the random access memory sticks into their respective slots on the motherboard.The last major component of the build is the power supply. This connects directly to each of the separate components to supply electricity. Learning to build computers by myself was very easy. The key to success with computers is to stay calm and remain calm. I self-taught myself how to build a computer was as easy as reading the manual. All the supplied manuals I received with my components were very clear and accurate. They explain how to route wires, where to plug-in each component, and to make sure each part in seated properly.

Anticipated Challenges and Planned Responses
ANTICIPATED CHALLENGES AND PLANNED RESPONSES As our business enters the world of food industry, INTERNAL QUALITY CONTROL 1. Sanitation Problem Every food would not be one if it is not clean. It takes several stages to ensure that our products are not only edible or delicious, but most importantly safe for every consumer. This is also a serious matter of all food industries because its good name is at stake. Orion Foods Inc. being a competitive newcomer, will go through big paces to earn the marketââ¬â¢s trust, which is too costly. We have to respond to regulatory authorities which provide the compulsory national framework for food or meat hygiene programmes through laws and regulations. Response Hygienic measures are to be taken during the various processing steps in the manufacture of meat products ââ¬â the Meat Processing Hygiene.This is part of a firmââ¬â¢s Quality Management (QM) based on the following three principles crucial for meat processing operations: * Prevent m icrobial contamination of raw materials, intermediate (semi-manufactured)goods and final products during meat product manufacture through absolute cleanliness of tools, working tables, machines as well as hands and outfits of personnel. * Minimize microbial growth in raw materials, semi-manufactured goods and final products by storing them at a low temperature. Reduce or eliminate microbial contamination by applying heat treatment at the final processing stage for extension of shelf life of products Fig. *** Microbiological contamination in the meat processing chain Figure *** shows the extent of contamination among meat processing operations, and the possible remedies, if any. If these processes were relinquished, it would highly contaminate meat which is unsuitable for further processing. Final products could be unattractive, tasteless or shorter in shelf life. In light of this issue, Quality Management schemes are needed.Such schemes have technical and hygienic components. The fo rmer encompasses product composition, processing technologies, packaging, storage and distribution. The hygienic aspect, related to meat processes, focuses not only for the final product, but also for the raw materials in various processes. It has two useful schemes: * Good Hygienic Practices (GHP) It follows general hygienic rules and applies recognized hygienic principles as well as laws and regulations issued by the competent authorities, referring to meat and meat products, equipment, Premises and personnel.GHP schemes are not factory specific, they apply to all types of meat plants. They are intended to establish and maintain acceptable hygienic standards in relevant meat operations. * Hazard Analysis and Critical Control Point (HACCP) HACCP are factory and product specific strictly sanitary control schemes that shall prevent, detect, control and/or reduce to save levels accidentally occurring hazards to consumersââ¬â¢ health. Despite GHP in place, accidental hazards cannot be ruled out and may occur at any processing step of the individual meat product.Specifically for meat processing plants, such hazards may be provoked by failures such as: * batches of incoming raw meat materials with abnormal tissues or * heavy contamination, * breakdowns in refrigeration, * failure in cooking/sterilization operations, * abnormal pH or a * in raw or finished products, * errors in levels of application of * curing salts and other additives, * technical problems in sealing of * vacuum packages or cans with * the risk of recontamination.
Determining the Strength of Acids and Bases
Determining the Strength of Acids and Bases Strong electrolytes are completely dissociated into ions in water. The acid or base molecule does not exist in aqueous solution, only ions. Weak electrolytes are incompletely dissociated. Here are definitions and examples of strong and weak acids and strong and weak bases. Strong Acids Strong acids completely dissociate in water, forming H and an anion. There are six strong acids. The others are considered to be weak acids. You should commit the strong acids to memory: HCl: hydrochloric acidHNO3: nitric acidH2SO4: sulfuric acidHBr: hydrobromic acidHI: hydroiodic acidHClO4: perchloric acid If the acid is 100 percent dissociated in solutions of 1.0 M or less, it is called strong. Sulfuric acid is considered strong only in its first dissociation step;à 100 percent dissociation isnt true as solutions become more concentrated.à H2SO4 ââ â H HSO4- Weak Acids A weak acid only partially dissociates in water to give H and the anion. Examples of weak acids include hydrofluoric acid, HF, and acetic acid, CH3COOH. Weak acids include: Molecules that contain an ionizable proton. A molecule with a formula starting with H usually is an acid.Organic acids containing one or more carboxyl group, -COOH. The H is ionizable.Anions with an ionizable proton (e.g., HSO4- ââ â H SO42-).CationsTransition metal cationsHeavy metal cations with high chargeNH4 dissociates into NH3 H Strong Bases Strong bases dissociate 100 percent into the cation and OH- (hydroxide ion). The hydroxides of the Group I and Group II metals usually are considered to be strong bases. LiOH: lithium hydroxideNaOH: sodium hydroxideKOH: potassium hydroxideRbOH: rubidium hydroxideCsOH: cesium hydroxide*Ca(OH)2: calcium hydroxide*Sr(OH)2: strontium hydroxide*Ba(OH)2: barium hydroxide * These bases completely dissociate in solutions of 0.01 M or less. The other bases make solutions of 1.0 M and are 100 percent dissociated at that concentration. There are other strong bases than those listed, but they are not often encountered. Weak Bases Examples of weak bases include ammonia, NH3, and diethylamine, (CH3CH2)2NH. Like weak acids, weak bases do not completely dissociate in aqueous solution. Most weak bases are anions of weak acids.Weak bases do not furnish OH- ions by dissociation. Instead, they react with water to generate OH- ions.
