Multiple-Part Short Answer - Essay Example The L. Monocytogenes has a lower pathogenic potential than other food borne pathogens. Therefore, the number of pathogens ingested through foods is still low. It is however inconsistent with the relatively high 50% lethal dose (LD50) (Lee 98). Therefore, the minimum dose required for causing clinical infection in the humans is yet to be determined but the large numbers of the L. Monocytogenes bacteria detected in the foods responsible for sporadic and epidemic listeriosis cases suggests it is still high The vibrio cholera, the cholera agent, is a normal inhabitant of the aquatic environment. It survives under a wide range of salinity and pH. The effect of selected environmental parameters can be identified through chemically defined solutions. From such conditions, the growth and activity of the vibrio cholera are seen as being affected and influenced by the low pH. The low pH was responsible for the reduced effectiveness and growth of the vibrio cholera bacteria. This condition of the pH altered the internal process of the bacteria causing it to slow down and reproduce slowly. Low pH contained less Na+ that was relevant for the growth of the bacteria. Hence, the vibrio cholera bacteria were bound to be minimal in number. From a past study by (Vimont, 1-4), vibrio cholera can be cultured for a period of 4days using and estuarine salinity of 25%. Salinity of the bacteria’s niche influenced the activity as measured through the uptake of 14C –amino acids. From the study of selected ions, it was evident that the activity and growth of the cholera were affected by pH. The LD50 is the dose at which a drug becomes lethal for 50% of the target population. It is expressed as the mass of the bacteria administered per mass of the target. Different bacteria types impact on the host differently. The lethal dose for particular bacteria can change over time due to various factors. This can be affected by the toxicity and the amount of the bacteria cells. As the

The Great Depression Essay -- American History

The causes and far-reaching effects of The Great Depression are examined. Discussion includes its impact on both American cultures and nations around the world. The role of World War II and the New Deal in overcoming the Depression are explored. The Great Depression began in October 1929, when the stock market in the United States dropped rapidly. Thousands of investors lost all of their of money and were forced to live on the streets often going without food. This crash led into the Great Depression. The ensuing period of 10 years ranked as the worst period of high unemployment and low business activity in modern times. Banks, stores, and factories were closed and left millions of Americans jobless, homeless, and without food. Many people came to depend on the government or charity to provide them with food. The Depression became a worldwide business slump of the 1930's that affected almost all nations. It led to a sharp decline in world trade as each country tried to protect their own industries. The Depression led to political turmoil in many countries such as Germany where poor economic conditions helped lead to the rise of Hitler. Franklin D. Roosevelt was elected President in 1932 and his 'new deal' reforms gave the go vernment more power and helped slow the depression. The Great Depression ended as nations increased their production of war materials at the start of World War II. This increased production provided jobs and put large amounts of money back into circulation. Several factors led to the great depression. One being the lack of diversification in the American economy. The prosperity of America had been basically dependent on a few industries like construction and the automobile and in the late 20's these industr... ...l deficit and Bennett cut back on government spending. A great burden on the country was Canadian National Railway, the government had to take over many railways and from that took in a debt of over two billion dollars. After seeing president Roosevelt's New Deal policy having good results in the U.S. Bennett introduced policies based on the New Deal. Bennett started up minimum wage and unemployment insurance. However Bennetts attempts to revive the economy were not nearly as successful as Roosevelt's. as a result the depression was worse in Canada than in the U.S., and this led to the defeat of Bennett in the 1935 election to liberal Mackenzie King. Like in the U.S. the Great Depression did not end until the outbreak of the second world war. A boost in the economy was created by a strong demand of Canadian goods in Europe and an increase of government spending.(ibid)

Following are excerpts from narrative essays: â€Å"Looking back on a childhood filled with events and memories, I find it rather difficult to pick on that leaves me with the fabled â€Å"warm and fuzzy feelings.† As the daughter of an Air Force Major, I had the pleasure of traveling across America in many moving trips. I have visited the monstrous trees of the Sequoia National Forest, stood on the edge of the Grande Canyon and have jumped on the beds at Caesar’s Palace in Lake Tahoe.† â€Å"The day I picked my dog up from the pound was one of the happiest days of both of our lives. I had gone to the pound just a week earlier with the idea that I would just â€Å"look† at a puppy. Of course, you can no more just look at those squiggling little faces so filled with hope and joy than you can stop the sun from setting in the morning. I knew within minutes of walking in the door that I would get a puppy†¦ but it wasn’t until I saw him that I knew I had found my puppy.† â€Å"Looking for houses was supposed to be a fun and exciting process. Unfortunately, none of the ones that we saw seemed to match the specifications that we had established. They were too small, too impersonal, too close to the neighbors. After days of finding nothing even close, we began to wonder: was there really a perfect house out there for us?† The following is an example of a famous narrative written by John Updike, â€Å"Hub Fans Bid Kid Adieu†: â€Å"The afternoon grew so glowering that in the sixth inning the arc lights were turned on–always a wan sight in the daytime, like the burning headlights of a funeral procession. Aided by the gloom, Fisher was slicing through the Sox rookies, and Williams did not come to bat in the seventh. He was second up in the eighth. This was almost certainly his last time to come to the plate in Fenway Park, and instead of merely cheering, as we had at his three previous appearances, we stood, all of us, and applauded.† Following are excerpts from descriptive essays: â€Å"Like his twisted feathers, his many scars, the reliable old owl chose the gnarled, weather-beaten, but solid branch often—it being a companion to the wise alone with the night and the last branch to creak in the heaviest wind. He often came to survey the fields and the clouds before his hunt, to listen to the steady sound of the stream passing through reeds under the bridge, while combing his feathers for the unwanteds—whatever they might be.† Here is a descriptive essay about a first visit to a favorite diner written by a student at Roane State Community College:†When entering the door at Lou’s, two things are immediately noticeable: the place is rarely empty and seems to consist of a maze of rooms. The first room, through the door, is the main part of the restaurant. There is another, rarely used, dining room off to the right. It was added during the oil well boom of the seventies. Through the main dining room is yet another room; it guards the door leading into the kitchen. This room contains the most coveted table in the place. The highest tribute Lou can bestow on anyone is to allow them access to seats at this table. This table is the family table; it is reserved for Lou’s, and her daughter Karen’s, immediate family and treasured friends.† Here is an example of a descriptive essay from St. Cloud State:†Billy Ray’s Pawn Shop and Lawn Mower Repair looked like a burial ground for country auction rejects. The blazing, red, diesel fuel tanks beamed in front of the station, looking like cheap lipstick against the pallid, wrinkled texture of the parking lot sand. The yard, not much larger than the end zone at General G. Patton High School on the north end of town, was framed with a rusted metallic hedge of lawn mowers, banana seat bicycles, and corroded oil drums. It wasn’t a calico frame of rusted parts, but rather an orchestra of unwanted machinery that Billy Ray had arranged into sections. The yellow-tanked mowers rested silently at the right of the diesel fuel. Once red, now faded orange, mowers stood at attention to the left. The oil barrels, jaded and pierced with holes, bellared like chimes when the wind was right. The bikes rested sporadically throughout the lot. In the middle of it all was the office, a faded, steel roof supported by cheap two-by-fours and zebra paneling. Billy Ray was at home, usually, five blocks east of town on Kennel Road.† Following are excerpts from exposition essays: â€Å"This family was a victim of a problem they could have avoided-a problem that, according to Florida park rangers, hundreds of visitors suffer each year.† Several times a month,† ranger Rod Torres of O’Leno State Park said, â€Å"people get scared and leave the park in the middle of the night.† Those people picked the wrong kind of park to visit. Not that there was anything wrong with the park: The hikers camped next to them loved the wild isolation of it. But it just wasn’t the kind of place the couple from New Jersey had in mind when they decided to camp out on this trip through Florida.† Here is an example of a student model answer of an Expository Essay from The Write Source:†Did you know that 7 out of 10 students have cheated at least once in the past year? Did you know that 50 percent of those students have cheated more than twice? These shocking statistics are from a survey of 9,000 U.S. high school students.Incredibly, teachers may even be encouraging their students to cheat! Last year at a school in Detroit, teachers allegedly provided their students with answers to statewide standard tests.†Here is an another example of an expository essay. This example comes from Essay Start:†Throughout history and through a cross-section of cultures, women have transformed their appearance to conform to a beauty ideal. Ancient Chinese aristocrats bound their feet as a show of femininity; American and European women in the 1800s cinched in their waists so tightly, some suffered internal damage; in some African cultures women continue to wear plates in their lower lips, continually stretching the skin to receive plates of larger size. The North American ideal of beauty has continually focussed on women’s bodies: the tiny waist of the Victorian period, the boyish figure in vogue during the flapper era, and the voluptuous curves that were the measure of beauty between the 1930s and 1950s. Current standards emphasize a toned, slender look, one that exudes fitness, youth, and health. According to psychologist Eva Szekely, â€Å"Having to be attractive at this time . . . means unequivocally having to be thin. In North America today, thinness is a precondition for being perceived by others and oneself as healthy† (19). However, this relentless pursuit of thinness is not just an example of women trying to look their best, it is also a struggle for control, acceptance and success.† Finally, here are excerpts from argumentative essays: â€Å"Gun control has been a controversial issue for years. A vast majority of citizens believe that if gun control is strictly enforced it would quickly reduce the threat of crime. Many innocent people feel they have the right to bear arms for protection, or even for the pleasure of hunting. These people are penalized for protecting their lives, or even for enjoying a common, innocent sport. To enforce gun control throughout the nation means violating a persons Constitutional rights. Although some people feel that the issue of gun control will limit crime, the issue should not exist due to the fact that guns are necessary for self defense against crime, and by enforcing gun control is violating a citizen’s second amendment right to bear arms.† Another examples of an argumentative essay comes from Bogazici University:†Throw out the bottles and boxes of drugs in your house. A new theory suggests that medicine could be bad for your health, which should at leastcome as good news to people who cannot afford to buy expensive medicine. However, it is a blow to the medicine industry, and an evenbigger blow to our confidence in the progress of science. This new theory argues that healing is at our fingertips: we can be healthy by doing Reikion on a regular basis.† On Essay By Example, on the other hand, the sample argumentative essay addresses online games and socialization:

Stakeholder Concerns Corporate Management - 1619 Words

Stakeholder Concerns Investors For most investors, the primary concern is profit on their Calfrac investment. However, a certain group of investors also consider social good as an issue of great importance and as a result, practice social investing. Another major concern for an overwhelming majority of investors is the amount of risk they take on. These investors consider the amount of risk an ownership stake in a company entails and choose not to invest in companies that are over exposed to a single industry, have a track record of inefficient management or are operating in a dying industry etc. Calfrac has recently disclosed that its board of directors have approved a $12 million plan to further the expansion in Latin America (Healing, 2015). This shows that Calfrac’s management is committed to making the company more valuable thus satisfying the investors’ need for a strong ROI. The expansion also reduces Calfrac’s risk due to the fact that it is becoming more diversified and won’t take substantial losses in case one of its regional operations face a downturn. To satisfy ethical investors, Calfrac has taken a strong lean towards corporate social responsibility. The company makes an effort to reduce its environmental footprint through the use of efficient technology and was recognized by United Way as a â€Å"Community Builder† in 2014, further increasing Calfrac’s reputation as a socially responsible company.
