Whooping Chough Essays - Pertussis, Burkholderiales, RTT

Whooping Chough Whooping cough which is also known as Pertussis is caused by infection by the Bordetella Pertussis bacteria. It is a highly contagious bacterial disease that affects the respiratory system and produces spasms of coughing that usually end in a high-pitched whooping sound. In this report I will describe how Pertussis is spread, contracted, what treatments are available for it and the prognosis for the patient. I will also tell you about the many symptoms of the disease. Etiology: Pertussis is caused by Bordetella Pertussis the bacteria invades the nose and throat and then the trachea followed by the bronchial tubes of the lungs. People usually contract the bacteria through the air when an infected person coughs or sneezes. Then people inhale or come in contact with the infected saliva. People who have been immunized in the past may still develop infection but it is usually atypical or very mild that is another cause of whooping cough. The incubation period is usually about 7 days. Morphology & Diagnosis: Pertussis is a round shaped gram positive bacteria. Some of the symptoms of Pertussis include runny nose, coughing that may be dry or may produce sputum. Along with a fever usually 102F or lower. Severe coughing attacks that ends in a high-pitched crowing sound when inhaling or it will end in a high-pitched "whoop". The coughing spells may end in a momentary loss of consciousness and or vomiting. It also results in difficulty at breathing. It also can cause some people to have diarrhea. When some small infants have long spells of coughing they usually begin to cry which causes them to choke on there own tears. Pertussis can be treated by DtaP which is a vaccine that protects children against the disease. During epidemics, health care providers or others at risk may be advised to receive a booster dose of the vaccine. The immunization is not 100 percent effective and has slowly becomes less effective over the past few years. Some tests that can be performed to tell if a person has contracted are to take a culture of the secretions from the nose and mouth and throat. A complete blood count or CBC which measures the number of red blood cells and white blood cells in the blood. If there is an with an elevated number of white blood cell count characterized by large numbers of lymphocytes. There are also serologic tests for Pertussis. Treatment: The Treatments include Erythromycin which is an antibiotic that is administered and may shorten the duration of the symptoms. Infants under 18 months of age require constant supervision because breathing may temporarily stop during spells of sever coughing. Infants with severe cases should be hospitalized. An oxygen tent with high humidity may be used. Intravenous fluid may be given if coughing spells are severe enough to prevent enough fluid intake by mouth. Sedatives may also be prescribed for young children. Cough suppressants are usually not helpful and should not be used. Prognosis: The prognosis for a person who leaves Pertussis untreated in infants has a poor outcome. The disease has a one percent to 2 percent death rate. Death may occur from lack of oxygen to the brain and bronchopneumonia. Some other complications that may occur are slowed or stopped breathing, nose bleeds, pneumonia, convulsions which are caused by a lack of oxygen and can cause permanent brain damage. Some of the more serious effects are anoxic encephalopathy, cerebral hemorrhage, seizures and developmental retardation. Miscellaneous: In Ethiopia rural doctors give a vaccination for Pertussis to people in street markets in an effort to increase the immunity rate of their country. Pertussis has becomes an epidemic about every 2-4 years. It usually affects non-immunized children with a history of contact to the bacteria the most. Personal Reflection: Matts reflection: When I think of Whooping cough I don't think of it as a major epidemic. The reason why I believe this is because there is not much information on the subject and I had a very difficult time finding pictures of the bacteria and its effects. I suppose that if 10 out of every 100,000 people are infected with it then it must not be a very large problem. The disease doesn't to seem to have very sever side effects if it is left untreated. I am almost certain that in a few more years Whooping cough will disappear. Roberts reflection: My opinion is a little different than Matts but in some ways I feel the same. First off I do agree that in this

Mary Ann Shadd essays

Mary Ann Shadd essays Mary Ann Camberton Shadd was born into the loving arms of Abraham Doras Shadd and Harriet Parnell on October 9, 1823 in Wilmington, Delaware. She was the eldest of 13 children. Mary grew up a free black in a slave state. She saw many frightened escaped slaves, as her house was a station where her family helped and sheltered them. This and being influenced by her father made her determined to change the way things were as much as she could. Mary Ann Camberton Shadd is a hero because she fought for equality, she faced the people who thought different, and she was definitely one of the many people to shape the way our world is today. Mary published many articles, a newspaper, and spoke out about her beliefs. She wrote many articles for the North Star, a newspaper about black independence and self-respect, after the publisher read and was impressed by her pamphlet Hints to the Coloured People of the North. A few years later she published a booklet, Notes of Canada West to encourage blacks to live in Canada as slavery was abolished in Canada on August 1, 1834. Mary also began writing many anonymous articles for other papers, in which she attacked one of her competitors, Henry Bibb. In August of 1852, Mary founded the Provincial Freeman. She used the paper to tell about events, to investigate the truth, and to express her opinion. When Bibb commented about his opponents at the Provincial Freeman, he said that they were a set of half cracked, hot headed individuals. He also stated that the newspaper is unworthy of the support of the well-wishers of our race. Its publication ended in 1861. Other then writing and publishing, Mary spoke out. She travelled the United States and Canada lecturing mainly about racism and womens rights. A reporter for Frederick Douglass Paper states that she told ...one of the most convincing and telling speeches i ...

Operations, Logistic and Supply Chain Management Essay

Operations, Logistic and Supply Chain Management - Essay Example With the invention of the electric sewing machine, the ability to mass produce garments gave businesses much more flexibility in design that ultimately complicated measuring productivity as it included many new variables both human capital-related and manufacturing modifications needed to serve complex social markets. By 1900, productivity in industries had been improved by 500 percent with the ability to rely on electricity to power sewing machines (Schmeichen, 1984). Productivity was now being measured by much more complex statistical and process systems, taking into account not only units of labor and output, but apparel variations, customer demand in key target regions of the country, facilities management, quality control systems, and recognition of costs for unique production systems to meet new design demand. The ability to provide innovation in apparel and textiles altered the demand of customers throughout the nation and internationally during a period where global trade was on the increase, demanding new measures of productivity to ensure profit growth and efficiency on various garment and textiles production systems. Whereas in previous years using non-electric sewing machines, productivity was a measure of the human capability and capacity to generate output, new systems allowing for elements of automation were added to productivity calculations that required more management intervention in assessing productivity and the development of training on automated and fast-output textile and apparel production systems. Essentially, the introduction of the electric sewing machine in 1889 completely altered the role of management in establishing quality standards, measuring productive outputs, assessing recruitment needs for more skilled labor to improve productivity, and establishing controls in multi-system production efforts. The Transformation in Restaurants One of the most common themes in restaurants today is the establishment of Total Quality Manageme nt, since brand sentiment and service delivery related to customer satisfaction are critical to sustaining competitive advantage and building consumer loyalty. The â€Å"diversity of customer preferences† as it relates to pricing, quality menu outputs, and service delivery dictate how the business differentiates its brand from other competing restaurants (Thompson, 2008, p.148). Transformation in this industry, as driven by consumer influence, occurs continuously as the business attempts to establish a culture that is driven toward producing quality food and service outputs that fluctuates with changing diner lifestyles and needs in consumption. In the restaurant, there are inter-dependencies between the cooking staff, management and service staff that must have an operational system of best practice established to ensure total quality outputs. In such a highly competitive industry, the business must consider how to position itself among competition with a heavy reliance on m arketing, promotion and customer satisfaction establishment. Such satisfaction requires that price is in-line with quality, that service is performed according to branding expectations and pricing, and that procurement of items meet with anticipated food costs and pricing structures established. Transformation occurs with new menu

Entrepreneurship Acunu Ltd Assignment Example | Topics and Well Written Essays - 1250 words

Entrepreneurship Acunu Ltd - Assignment Example Using the above approach the objectives of Acunu Ltd could be described as follows: a) the firm emphasizes the use of information as a strategic tool for supporting daily operations of firms in all industries; in fact it is the rapid, even on real-time, process of information/ data on which Acunu Ltd focuses in order to secure its competitiveness in the UK market; b) Acunu Ltd has developed a unique software programme, the Acunu Analytics, which is able to offer data analysis support of high quality using advanced features, as described in the organizational website; the promotion of this programme, as the basis of its services, is among the key objectives of Acunu Ltd; c) Acunu Analytics, the key programme of Acunu Ltd, addresses businesses in all sectors; there are no specific criteria set by the firm in regard to the provision of its services; this means that the above programme can be applied in a quite wide business area; the approach used by Acunu Analytics for communicating wi th its potential customers can be characterized as generalist approach (Kozami 2002), not being limited on the basis of specific terms. A successful mission statement needs to be broad so that it cannot easily become ‘outdated if the business changes its objectives/ priorities’ (Lamb et al. 2008, p.35). Moreover, such mission statement would focus ‘on the market that the firm is interested to attract’ (Lamb et al. 2008, p.35); a description only of the goods/ services of a business would not constitute an effective mission statement. In Acunu Ltd there is no a clear description of the mission statement; after reviewing the organizational website the following mission statement would result: the firm aims to help businesses to secure their growth by using their data more wisely. As a concept, business vision is usually related to the identification of ‘a unique path for the business’ (Wenger 2007, p.19), i.e. a path that would make the business to secure its competitiveness.  Ã‚  

An analysis of entrepreneurial theory Essay Example | Topics and Well Written Essays - 4000 words

An analysis of entrepreneurial theory - Essay Example Many new entrepreneurial firms fail as a result of entrepreneurs not fully understanding problems associated with their business models. It is rather commonplace for entrepreneurs to jump blindly into a new business model without properly planning that includes construction of a concise and well-developed business plan. A successful entrepreneurial venture must be considerate of the entire value chain, including marketing, human resources, technology, logistics and production in order to have a viable business model that can productively support the desired vision. Failure of the entrepreneurial venture occurs regularly as entrepreneurial leaders do not effectively measure the business’ holistic capabilities and capacities needed to service a market which leads to a lack of competitiveness in the firm’s competitive market. In order to properly service the external market effectively and profitably, it is critical to understand what constitutes the dynamic of the post-re cession markets and then attempt new strategies to align the entrepreneurial enterprise with these conditions and dynamics. As one example, the post-recession consumer is now more concerned about the ethical values and behaviours of the organisation. A study conducted by Oh and Yoon, utilizing a sample of 343 different consumers, identified that when an organization illustrates that it maintains altruistic values and activities, consumers maintain a more positive perception of this business over that of businesses without a promoted ethical stance.

Effect of Carbon Atoms Number in Alcohol on Combustion

Effect of Carbon Atoms Number in Alcohol on Combustion Research Question How does the number of carbon atoms in the hydrocarbon chain of primary alcohol affect its enthalpy change of combustion? Independent Variable The independent variable in this investigation is the number of carbon atoms in the hydrocarbon chain of primary alcohol. Five different primary alcohol will be used, namely, methanol, ethanol, propan-1-ol, butan-1-ol and pentan-1-ol. Dependent Variable: The dependent variable in this investigation is the enthalpy change of combustion of primary alcohol. Enthalpy change of combustion is the energy released when one mole of fuel is completely burnt in oxygen to form carbon dioxide and water. To measure the enthalpy change of combustion, the heat given out during combustion is first absorbed by water which is calculated by q = mc à ¯Ã‚ Ã¢â‚¬Å¾T where m is the mass of water, c is the specific heat capacity of water and à ¯Ã‚ Ã¢â‚¬Å¾T is the temperature change of water. The heat given out is then divided by the number of moles of alcohol used during the investigation. As combustion is an exothermic reaction, a negative sign is added to give the final enthalpy change of combustion. Control Variables: The table below shows the variables that have to be controlled: Hypothesis: The higher the number of carbon is in the hydrocarbon chain, the greater the enthalpy change of combustion of the primary alcohol. One of the evidence for this hypothesis comes from the IB Chemistry data booklet. The standard enthalpy change of combustion for methanol, ethanol, propan-1-ol and butan-1-ol are –726 kJmol-1, –1367 kJmol-1, –2021 kJmol-1 and –2676 kJmol-1 [1]respectively. Another way to get this trend is to use the average bond enthalpy to estimate the enthalpy change of combustion. Though average bond enthalpies are just average values only, they do give an insight on the trend of the enthalpy change of combustion of different alcohol. The general formula for alcohol is CnH2n+2O. The general equation for combustion of alcohol is CnH2n+2O (l) + 1.5nO2 (g) à ¯Ã†â€™Ã‚   nCO2(g) + (n+1)H2O(l) When the number of carbon increases by one, the following table shows the extra bonds to be broken and extra bonds formed: The average bond enthalpies for the above bonds are shown in the table below: [2] The net change in enthalpy change when one more carbon is added = + 2 Ãâ€" 413 + 347 – 2 Ãâ€" 746 – 2 Ãâ€" 464 = – 1247 kJmol-1 Thus, the enthalpy change of combustion of primary alcohol will decrease by 1247 kJmol-1 (more negative) when one more carbon is added to the hydrocarbon chain. Apparatus: 100 cm3 measuring cylinder ( ±1 cm3) Ãâ€" 6 (one for each alcohol and the other for water) (2 d.p. ) Electronic balance ( ±0.01 g) Ãâ€" 1 Tripod Ãâ€" 1 Copper container with lid Ãâ€" 15 (one for each trial) Stand and clamp Ãâ€" 1 (use to hold the thermometer in position) Mercury in glass thermometer ( ±0.1à ¯Ã¢â‚¬Å¡Ã‚ °C) Ãâ€" 2 (one is used to measure temperature of water and the other used for monitoring the temperature of surrounding) Stirrer Ãâ€" 1 Aluminium heat shield Ãâ€" 4 (to reduce heat loss) Spirit burner with wick Ãâ€" 15 (one for each trial) Lid Ãâ€" 1 (for extinguishing the flame) Stopwatch ( ±0.01 s) Ãâ€" 1 Ruler ( ±0.1 cm) to measure the length of wire and the position of the thermometer Scissor Ãâ€" 1 (used to cut the wick) Chemicals 750 cm3 of distilled water (50 cm3 for each trial) 100 g of each of the following primary alcohol at a concentration of 90%. Methanol, ethanol, propan-1-ol, butan-1-ol and pentan-1-ol Procedures Prepare a spirit burner. Cut the length of its wick to approximately 3.0 cm (the portion outside the burner) with a pair of scissors and a ruler. Measure 50 cm3 of methanol with a 100 cm3 measuring cylinder and pour it in a spirit burner. Weight the spirit burner with an electronic balance. Record the mass of the spirit burner in the table below. Measure 50 cm3 of distilled water with another 100 cm3 measuring cylinder and pour it in a copper container. Place the copper container on a tripod and cover it with a lid. Use stand and clamp to hold a thermometer in the beaker of water. Use a ruler to make sure that the bottom of the thermometer is 1.0 cm from the bottom of the beaker and make sure the thermometer is approximately located at the centre of the beaker. Record the initial temperature of the water and put it in the table below. Place a stirrer in the water. Stir the water throughout the process of heating. Surround the whole setup with heat shield made of aluminium to reduce heat loss. Ignite the wick of the spirit burner with a lighter. Place the spirit burner under the beaker. Immediately start the stopwatch and wait for two minutes. Stop the stopwatch after two minutes. Use a lid to extinguish the flame. Record the highest temperature reached by the thermometer and put it in the table below. Allow the spirit burner to cool. Weigh the final mass of the spirit burner with an electronic balance. Put the mass in the table shown below. Repeat the experiment (Step 1 to 16) two more times. Repeat the same experiment (Step 1 to 17) for other primary alcohols (i.e. ethanol, propan-1-ol, butan-1-ol and pentan-1-ol). Table for recording raw data and some processed data: Data Processing The mass of fuel used (m) is calculated by subtracting the final mass of spirit burner from the initial mass of spirit burner. The temperature change (à ¯Ã‚ Ã¢â‚¬Å¾T) is calculated by subtracting the final temperature by the initial temperature. The heat (q) absorbed by water can be calculated by the formula q = mc à ¯Ã‚ Ã¢â‚¬Å¾T where m is the mass of water used: 50 g (as the density of water is 1 g cm-3) c is specific heat capacity of water: 4.18 Jg-1K-1 Number of moles of fuel used can be calculated by dividing the mass of fuel used (m) by the molar mass of the fuel. The molar mass is found by adding up the relative atomic mass of the element involved. For example, the molar mass of methanol (CH3OH) is 12.01 + 4 Ãâ€" 1.01 + 16.00 = 32.05 gmol-1. The enthalpy change of combustion of alcohol is found by dividing the heat by the number of moles of fuel with a negative sign added to show that it is exothermic. A graph is plotted with enthalpy change of combustion (y-axis) against the number of carbon atom is the hydrocarbon chain of the primary alcohol (x-axis). Compare this graph with the graph in the hypothesis. Safety Alcohols are flammable. Avoid naked flame near alcohol. [1] Chemistry data booklet (First examinations 2009).

King Philip’s War Essay -- History Historical Essays King Pillip

King Philip’s War In 1675, the Algonquian Indians rose up in fury against the Puritan Colonists, sparking a violent conflict that engulfed all of Southern New England. From this conflict ensued the most merciless and blood stricken war in American history, tearing flesh from the Puritan doctrine, revealing deep down the bright and incisive fact that anger and violence brings man to a Godless level when faced with the threat of pain and total destruction. In the summer of 1676, as the violence dispersed and a clearing between the hatred and torment was visible, thousands were dead.(Lepore xxi) Indian and English men, women, and children, along with many of the young villages of New England were no more; casualties of a conflict that was both devastating to the lives and the landscape of New England, as well as the ideologies of both the Indians and the English Puritans that inhabited this land.(Lepore 18) King Philip’s war was not the basic Indian war that plagues American history. It was not the first archetypal Settler vs. Savage conflict, and nor would it be the last. King Philip’s war was a terribly violent and destructive conflict, which was sparked by the desires of maintaining cultural identity and preserving power and authority, both in societal and religious capacities upon what one believed to be his land. (Leach 21) Saying that this conflict left all of 17th century New England in a state of confusion is far more than an understatement. With nothing won, and terrific loss, the early Americans, both English and Indian, were unsure of their own, as well as each other’s identity. This crisis, whether they are aware of it or not, has impacted Americans and their ideologies of themselves for hundreds of years. (Lepore 18) The Puritans came to this New World roughly forty to fifty years before this conflict began, but the guarantee of this conflict arrived in the same boats as they did. Something often misunderstood is that the Puritans themselves were not separatists, in fact they left England with the firm desire of staying English, maintaining their cultural identity, and remaining faithful and true to the majesty of the homeland. They had left England with the desire of religious freedom, and with hope of having somewhere to practice freely and safely within the boundaries of English oriented society, but free of the sinful and heretical p... ...n, and made an outstanding effect on the development and cultural identity on New England. It altered the mind set of an expanding and driven people, and established a strong enough foundation for an ethnic debate that has been a constant throughout most of American history. These social, political, and cultural effects are what make this war such an event worth noting. As was stated before, this was neither the first, nor was it the last of the Indian wars in developing America, but it is the only one to expel such consequences and to so greatly effect the landscape that is American history.
