Free Essays on Miracle Or Mirage

Miracle or Mirage Could the Miracle of Helena really be the Mirage of Helena? A prominent editor for the New York Times has hailed the original article as The Miracle of Helena, while urging readers to give the article way more credit than it deservers. According to an article written by Steven Milloy, on Friday October 17, 2003; (The known publisher of Junk Science.Com and known scholar and published author) The Second Hand Smoke Scam. Milloy claims there is not enough factual evidence to support the theory that the ban on smoking in Helena was associated with the drop in heart attack patient admissions at the local hospital. In 2002 the citizens of Helena opted to ban smoking in all public buildings. After a six-month period the ban was rescinded. During the six-month period doctors at a local hospital reported that heart attack patient admissions had dropped. Then after the ban was rescinded the admissions of heart attack patients rebounded to the pre-ban levels. Milloy states there was simply no study to account for heart attack rates dropping due to the smoking ban. Since there had been a similar drop four years prior in 1998. This drop was unrelated to a smoking ban. This study was not easy to evaluate because there was no study. The results were a slide show presentation at the annual meeting of the American College of Cardiology and six months later no study has been released to the public. So how did the editor at the New York Times get his facts? Given the fact there were no medical test done on any of the heart attack patients admitted prior to, during, or after the smoking ban it would be impossible to determine whether or not the attacks were caused by second hand smoke, genetics, life style, or environmental factors. Therefore to say that the drop in heart attack patients during the ban was due to second hand smoke would be outrageous. This seems to be more of a mirage of Helena than a miracle of Helena.

Asthma as a Chronic Inflammatory Disorder Essay

Asthma as a Chronic Inflammatory Disorder - Essay Example It is suggested that 90% of the deaths caused by asthma can be prevented if proper measures are taken without wasting time(Anderson et al., 2007). In the United Kingdom, the overall percentage of the asthma patients has slightly declined, however, the number of patients has increased. This is because the population continues to increase, and the rate of increase of asthma patients in the population is lower to the population growth rate. Some of the common triggers of asthma include respiratory infection, cigarette smoke, and allergens like pollen grains, dust and other particulate pollutants, sudden changes in temperature, stress/anxiety, and exercise. The asthma attack is characterized by the narrowing of airways; which occurs due to the tightening of muscles, excessive secretion of mucus, and swelling of epithelial lining in lungs (Bisgaard et al., 2012). All these events are triggered by one or more aforementioned causes. Asthma can prove lethal if it is not managed properly, tho usands of children lose their lives every year at the hands of asthma due to negligence on the part of parents and healthcare professionals. Though asthma is a reversible lung disease, slight negligence or delay in providing proper care may cost one’s life. Children with asthma are at a disadvantage; their activities are limited because of the fear of acute exacerbation. The restricted lifestyle coupled with precautionary measures builds psychological stress, which obviously not ideal for children during their growing years. Psychological stressors like fear, anxiety, and depression lead to impairment in learning at school and restrict their participation in activities enjoyed by their age fellows(Chait, 2015). Asthma does not have a specific cause; the inflammation of respiratory tract can be triggered by numerous sources. Therefore, there are multiple events, stimuli, and allergens that can affect the associative learning, and result in confused responses.

Planning and Enabling Learning Essay Example | Topics and Well Written Essays - 1500 words

Planning and Enabling Learning - Essay Example The 9th and the 12th academic year are the two most significant life paths that a student can pass through. Generally those two years guide the students to their chosen careers. To a greater degree though what will bring success in his/her life depends on the choice of subjects during these stages. Both parents and teachers play an immense role in directing children towards what education route to choose that would lead them to successfully university and career development. BTEC was established in 1984 and stands for the Business Education Council (BEC) and the Technician Education Council (TEC). BTEC course is based on continuous assessment rather than on annual exams. The BTEC course incorporates opportunities for work experience and gaining real life skills through case studies. BTEC course is designed to enhance the demands of employers in modern society and to allow students to quickly progress to their university degree. BTEC has proved its operational success and effectivenes s in the last 25 years and is gaining popularity as students are mo focused on day to day abilities and the course's flexible nature. Statistically, more than 1 million students enrolled on BTEC course for the academic year 2006/2007 (Edexcel BTEC Course, 2009).Institutions and students all around the world value the BTEC brand because it delivers excellent vocational qualifications that signify global recognition to the chosen area of studies. Practically it does not matter whether the programme is taught in London, Beijing or Dubai, since the quality assurance procedures assure that the candidates are awarded with standardized and internationally recognized qualifications. BTEC diplomas are organized to provide specialist work-related abilities in a wide range of sectors. BTEC courses equip students with valuable and lifelong skills and knowledge required for their career progress, and/or for the continuation of their vocational studies at higher academic level. During the BTEC course learners meet with professionals from the preferred industry in order to receive adequate consultation and the specialists to supervise the programme and progressive activities of the students. All BTEC seminars cover core and expert units, thus they have standard format and clear guidance about the requirements of the qualifications assessed. There is assessment criteria applied. The learners get Pass, Merit, or Distinction for each module of the programme. This means that the learners have to collect a number of points to obtain the overall Pass Grade for the programme. No external examinations apply in BTEC programmes (Edexcel BTEC course, 2009). When designing the cou rses providers work closely with employers from different sectors to create an inspiring atmosphere where students gain the skills they need to either start employment immediately after graduation or continue to a higher education. The subject areas that BTEC cover are: Applied Sciences Children's Care, Learning and Development Engineering Hospitality Languages Public Services and Security Art and Design Construction Hairdressing, Beauty and Related Therapies IT and Computing Media Sport, Leisure and Recreation Business, Management and Services Education and Training Health, Care and Counselling Land and the Environment Performing Arts and Music Travel, Tourism and Transport Services - Decide on the envisaged group and identify the barriers The envisaged focused group is 12 graders. The barriers that learners at BTEC course can face while planning and organizing his ideas are several. First of all, when one is attempting to clarify and comprehend the functions or operations of the studied course, students can rarely imagine properly the object itself. For example, it will be difficult to communicate how to use a computer for the first time if this is not visually demonstrated. In order for learners to study the subject, they have to get the object related to it. In this way they will experience it in various directions and will build

Effect of Temperature on Lipase Essay Example for Free

Effect of Temperature on Lipase Essay Theory The higher the substrate concentration the more quickly product is produced (rate of reaction  increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from the cells. Hydrogen Peroxide is the poisonous by-product of metabolism. Catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown in the equations below. It is able to speed up the decomposition of Hydrogen Peroxide because the shape of its active site matches the shape of the Hydrogen Peroxide molecule. This type of reaction where a molecule is broken down into smaller pieces is called an anabolic reaction. Hypothesis The prediction would be such that as the substrate concentration increases, the rate of reaction will go up at a directly proportional rate until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached, then adding extra substrate will make no difference. The rate steadily increases when more substrate is added because more of the active sites of the enzyme are being used which results in more reactions so the required amount of oxygen is made more quickly. Once the amount of substrate molecules added exceeds the number of active sites available then the rate of reaction will no longer go up. This is because the maximum number of reactions are being done at once so any extra substrate molecules have to wait until some of the active sites become available. Variables Independent Variable(s) Concentration of substrate Dependent Variable(s) Rate of enzyme activity Control Variable(s) Temperature pH Pressure Apparatus S. No Item Qty. Size, Capacity, Amount 1 Graduated cylinder 1 500mL, 500cm3 2 Metal Stand 1 3 Catalase from Chicken Liver. Pour the hydrogen peroxide solution into the test tube containing the chicken liver and immediately put the cork with a transferring tube plugged into it connecting it to a rubber tube leading to a filled inverted graduated cylinder to measure the amount of gas in mL (cm3) formed. 3. Bubbles should start to rise up the tube and the water level in the graduated cylinder should move down. 4. Record the water level after every 30 seconds for a total period of 5 minutes. 5. Do the same for 4%, 6%, 8%, 10%, 12% and 14% and record the readings for them individually. When the concentration of Hydrogen Peroxide is increased, the rate of reaction increases at a directly proportional rate until the concentration of Hydrogen Peroxide reaches about 10%. If you double the concentration of Hydrogen Peroxide then the rate of reaction doubles as well. When the concentration is doubled from 8-16% the rate goes up from 1. 65-2. 97 Cm3 Oxygen produced per second, which is an increase of 1. 8 times. I would expect the rate to increase two times if the Hydrogen Peroxide concentration is increased two times because there are twice as many substrate molecules which can join onto the enzymes active sites. The reason that the number is less than two times could be put down to the fact that at 10% the Enzymes active sites may already be close to being saturated with Hydrogen Peroxide. There may also be some experimental error which causes the inaccuracies. After 10% the increase in the rate of reaction slows down. This is shown by the gradient of the graph going down. At this point virtually all the active sites are occupied so the active sites are said to be saturated with Hydrogen Peroxide. Increasing the Hydrogen Peroxide Concentration after the point of saturation has been reached will not cause the rate of reaction to go up any more. All the active sites are being used so any extra Hydrogen Peroxide molecules will have to wait until an active site becomes available. The theoretical maximum rate of reaction is when all the sites are being used but in reality this theoretical maximum is never reached due to the fact that not all the active sites are being used all the time. The substrate molecules need time to join onto the enzyme and to leave it so the maximum rate achieved is always slightly below the theoretical maximum. The time taken to fit into and leave the active site is the limiting factor in the rate of reaction. Limitations a) There is a slight delay between pouring the Hydrogen Peroxide into the catalase, putting the bung on and starting the stopwatch. This will slightly affect all the results but as I carried out all the three steps in the same way for all the experiments it should not make any difference to the overall result. b) It is also impossible to precisely measure out the amounts of Hydrogen Peroxide and catalase each time. As the scale on the pipettes shows the volume to the nearest mm3 the volume of the solutions that I used should be correct to the nearest mm3. The volume of gas in the test tube to start with is slightly affected by the amount which the bung is pushed down each time, if the bung is pushed down further then the volume in the tube will be less so the 30cm3 of gas is reached faster. c) Due to the fairly slow speed of our reactions it is only possible to measure the time of the reaction to the nearest 0. 1 second even though the stopwatch shows the measurements to the nearest 0. 01 second. d) Human errors such as inappropriate readings, time difference in readings, stopping flow of air by accidentally compressing rubber tube†¦ could also have been made

Is Development Methodologies In Financial :: essays research papers

Introduction & Overview of the Company Marks and Spencers is a large UK based retailer with 683 branches in 2 continents. Following the deregulation of the UK financial sector in the mid eighties the company decided to use its experience, capital, and brand power to branch into the lucrative financial services industry offering personal loans, life insurance & pensions, and savings & investments services such as Unit Trusts and ISAs through the company Marks and Spencers Financial Services. Financial Services is now one of the fastest expanding areas of Marks & Spencers, MSFS employs more than 1,400 staff at its purpose built headquarters in Chester, and has dedicated financial services areas in 70 M&S stores across the country. The Information Systems department has 50 employees who come from analysis, design, & programming backgrounds, much of which has been gained with Marks & Spencers plc. The majority of these employees are based in the Chester head office, and systems are developed ‘in-house’. IS project s under development include the introduction of Individual Savings Accounts, with other likely future projects including telephone banking, credit cards, and auto/property insurance. The fact that MSFS has entered the Financial Services Sector comparatively recently and with a established IS knowledge base from the parent company has meant that existing information systems have been well developed in terms of technology and are compliant with the latest industry regulations. Therefore there is little or no need for redevelopment of existing systems in the short to medium term, and the ISD focus is almost exclusively on new market areas requiring Information Systems that can be started from scratch. The main exceptions to this are the possibility of introducing data warehousing to tap the potential of both MSFS’ and the parent company’s client database to better target MSFS customers, and the need to adapt existing systems for the introduction of the Euro, projects which will involve redesign of existing data stores and software. The company has grown very quickly, and IS projects have consequently grown considerably as can be seen by the size of the IT department. While there are still small to medium sized projects, some that are currently being considered will be on quite a large scale with several senior analysts working on each project. These projects are anticipated to require an IT department expansion of 50% over the next two years. Although MSFS’ IS projects share certain common characteristics in terms of their requirements, such as the need for a common ISD structure across projects, they vary considerably in size and strategic importance, with future developments looking likely expand those differences.

Management Protocol Essay

A protocol in the simplest words is a set of rules that allows and facilitates a connection to communicate between two computers. Protocols can be implemented through hardware or software. Whatever their scope, they are what govern networks and monitor them for effective communication. An internet protocol is more data oriented rather than connection oriented in the sense that it facilitates the exchange of data. Whatever the type of protocol is used, it is based on a few basic steps or prerequisites. These include detecting if a connection is possible, establishing connection, establishing rules of communication and messaging, editing messages, detect errors and termination of connection. Hence every protocol follows these steps. Protocols are important in the sense that we live in a networked society. Without protocols, this communication between computers would not be possible. There are famous protocols like the ones in the TCP/IP suite which are used on almost every computer. They however are ntot he only ones. Despite of many famous protocols like HTTP, FTP, IPv6, there are many others which have been developed over the years for specific purposes or as an alternate to the more famous protocols. One of these is the SNMP (Simple Network Management Protocol). The main purpose of this protocol is to detect and manage computers on a network. It uses variables to store and retrieve data regarding whether connections are present and if yes then also their status regarding connectivity etc. Another protocol is the SOAP (Simple Object Access Protocol). It is one that manages computers by communicating through XML based objects instead of packets over a network. References: Mukhi, Vijay. Kotecha, Sonal.

My Personal Philosophy of Education Essay - 890 Words

My Personal Philosophy of Education When I came to college, I debated on a major, trying to find a career that would be satisfying to me. After much pondering, I decided that education is the right path for me. I now find that not only do I think it is the right career, but I have a passion for helping children succeed. Education is a very important part of todays society. Teaching is a way to make society a better place for todays generation and our children. Teaching may not seem like a very important career to some people, but when I think back to some of my own teachers, I realize what an important part they played in my life. Many people have the desire to be a teacher from the time they†¦show more content†¦After the two of them talked about my tutoring, Mr. Brown started calling me Mr. Reichard instead of Dwayne. He said I should be treated as one of them, and they were addressed as Mr. or Mrs., I should be as well. I hope I can be a good educator as well as a role model, like these teachers were for me. A good teacher doesnt only teach the curriculum, but he or she also teaches children about life and social skills. A classroom should make children feel emotionally stable, because not all of them have that at home. A good teacher laughs with their students, but knows when discipline is necessary. Children need good teachers, and I intend on being one. Since all children have different styles of learning, I believe in incorporating different styles of teaching into the curriculum. If a teacher does this, all children have the advantage. For example, if Bob learns better by doing hands-on activities, and Joe learns better by reading the text, then Bob wouldnt comprehend as well if he had to read the text for every lesson. For this particular reason, I agree with John Dewey on his theory of Progressivism. This type of teaching causes curiosity and forces students to a higher level of knowledge. If the lesson doesnt challenge the students, it wont keep them interested. On the college level, teachers lecture, use videos, overheads, and cooperative learning groups to ensure that students are given the chance to learn.
