The Origin and Fate of the Universe †Physics Essay

The Origin and Fate of the Universe – Physics Essay Free Online Research Papers The Origin and Fate of the Universe Physics Essay After reading Stephen Hawking’s eighth chapter entitled, â€Å"The Origin and Fate of the Universe†, I was intrigued and fascinated by his method of thinking on the matter. According to Einstein’s initial general theory of relativity, the universe was formed with the occurrence of the Big Bang and it would eventually end with the event of the Big Crunch. But when consulting quantum effects further, the mass or energy initially created must ultimately be returned to the rest of universe. That means that black holes and singularities within it would disappear. The drastic clout that quantum effects have is very interesting and captivating. This is a universal topic because it involves every human being that has ever lived and will eventually decide our future. That is why I find this topic so relevant and fascinating. With the recent death of Pope John Paul II, I really found the part regarding the late Pope’s advice interesting. At the meeting with Stephen Hawking and others, the Pope instructed them all to pursue their interest in the evolution of the universe but not to delve into the Big Bang which is supposed to be the moment of creation. This is a very controversial subject with religion and science and I was intrigued by how they handled the situation. The model that Hawking had in mind revolved around the basis that when the universe expands, any matter or radiation in the universe becomes cooler. The temperature drops as the universe gets bigger. The temperature is a measure of the energy of the particles and when there are very high temperatures, such as the Big Bang, particles move so incredibly fast that they can avoid any attraction to each other due to the nuclear and electromagnetic forces. With the higher temperatures, particles contain more energy within themselves. So basically, with this theory, at the time of the Big Bang the universe had zero size and was infinitely hot. Then as time progressed, the universe expanded and the temperature decreased. This is the origin and fate of the universe through the eyes of Stephen Hawking himself.

Bio Lab Essay Example Bio Lab Essay Bio Lab Essay Santiago NevillePeriod 110/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins, and most enzymes activities occur within organism. They decrease activation energy, energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in -ase, enzymes ending in -ase. External factors, such as temperature, pH, and concentration of the substrate, affect the enzymes activity in the lab, pectase and cellulase will be used to compare different enzymes on apple sauce. The lab is designed to investigate the effect of different enzymes on apple juice production The combination of pectinase and cellulase will be the most effective simply because two is better than one. MATERIALS: apple sauce, pectinase enzyme, cellulase enzymes, funnels, filter paper, lab aprons, splash-proof goggles, paper towels, stirring rods, graduated cylinders, access to the water, paperclips, access to a stop watch, and access to a triple bean balance. Procedure: 1) Collect materials 2) Follow safety protocol ) Measure 1 tablespoon of apple sauce and place it in a cup 4) Add 10 drops of pectinase to the apple sauce and stir for 1 minute 5) Line a funnel with a coffee filter, place funnel in a graduated cylinder, empty the mixture into the funnel, and let it filter for 5 minutes. 6) Record the amount of juice collected 7) Repeat steps 1-5 with cellulase and water.

They are also proteins, and most Enzymatic activities occur within organism. They decrease the activation energy that is needed to start a chemical reaction. The problem was the effect that different enzymes have on apple sauce, and the lab was designed to investigate this. The combination of pectinase and cellulase will be the most effective simply because two is better than one. The hypothesis was correct because it collected the most amount of apple sauce with 3. 28 ml. We tested the enzymes by mixing it with apple sauce. We got our results by seeing which one collected the most apple sauce. The combination of both pectinase and cellulose was the most effective on apple juice production with 3. 28 ml. The water was the least effective with 0. 52 ml of apple juice collected. In the lab we all collaborated to get the most valid results we could get. The results were collected by testing each mixture in the same way and kept all the control variables constant. This experiment is valid because the controlled variables were kept constant. The independent variable was the type of enzyme or mixture we tested. The dependent variable was the amount (in ml) of apple juice that would be collected out of the coffee filter paper. The controlled variables were: to keep the amount of apple sauce the same, the size of the coffee filter paper, amount of each mixture, amount of time spent on mixing it with the apple sauce and the amount of time allowed letting it drop through the filter paper. The experiment taught us that the combination of the two enzymes was the most effective. Santiago Neville Biology Honors period 1

Post heartattack cardiac failure Essay Example | Topics and Well Written Essays - 3000 words

Post heartattack cardiac failure - Essay Example This essay is going to address the issue of heart attack in details and explain the measures one is supposed to take to avoid another heart attack in the future. Heart failure management includes a number of pharmacologic, nonpharmacologic and persistent strategies to reduce subsequent occurrences of heart attacks. Pharmacologic management includes the use of vasodilators, beta-blockers, diurectics, digoxin and anticoagulants. Nonphamacologic management entails physical activities, dietary sodium, fluid restriction and attention to weigh gain. Persistent strategies for heart failure are implantable cardioverter-defibrillators, electrphysiologic intervention such as pacemakers and cardiac resynchronization therapy, ventricular restoration and revascularization procedures such as coronary artery bypass grafting (Ketchum, 2011: 90). Heart failure patients should be examined for coronary artery disease, which is a major cause of heart failure. It also plays a role in heart failure progression through mechanisms such as ischemia, infarction and endothelial dysfunction. Studies reveal that patients suffering from coronary artery disease demonstrate a symptomatic and survival improvement with coronary artery bypass grafting (Clifford, 2008: 62). The sections that follow outline the most effective measures for providing support for CHF patients. Despite the deadliness of myocardial infarction and other chronic heart diseases, these measures, if well taken, have the ability to markedly improve one’s health outcomes. They also have the ability to reduce the burden on the health care system. Patients, their families and caregivers can reduce worsening of the CHF condition if they are familiar with the principles of myocardial infarction management and learn to monitor the symptoms and deterioration signs on a daily basis. Whether or not the victims are enrolled into a particular management program, the availability of supportive organization and

Sales planning and operations - Essay Example Sales can be stated as the lifeblood of a business.Earning sustained profitability is the basic aim of conducting sales activities in an organisation. In order to boost up the sales of LPPT Cola in the market, the corporation needs to identify the target market for their offered products. Subsequently, after recognising premium target consumer segment of the products which can facilitate to increase the sales of the company in the long run, the organization needs to make a comprehensive market analysis to recognise the specific requirement trends of the customers from the offered product (Treace, 2013). In the following step, LPPT Cola needs to make an outline of their sales plan. The company needs to study its targeted market thoroughly and consequently it needs to analyse the sales objectives as well as the requirement of manpower to reach the end-users (IILM, n.d.). As a Sales Director, there is a need to have a directional plan in place for the entire sales team at the outset. Mo reover, a contingency plan also needs to be prepared so that any untoward scenario in terms of unavailability of a sales team member is handled efficiently. At the same time, if the Sales Director of LPPT Cola finds it to be necessary, he can even interact with the concerned authorities of the same industry, which will help him to advise the marketing manager to sketch a detailed structure of the plan (The Sales Management Association, 2013). After the determination of the targeted market and sketching the sales plan, the next process will be the creating a network or connectivity. To make the consumers aware of the products of LPPT Cola, at the initial stage, the organization can take the aid of strategies such as telemarketing, e-mailing and door-to-door selling among others. In terms of pricing of the products, it is essential to prepare a competitive pricing to mitigate the threat of substitute products. With regard to the sales force, LPPT Cola needs to inculcate the strategy o f planning, coordination, controlling and motivating to ensure that customers are offered with best possible service. This strategy can ensure a sustained profitability from sales activities in the long run (Kundu, n.d). Structure of the Sales Department Learning Outcome (b) Business objectives are the aims, purposes and goals of the business. The significant role of business is to achieve its goals. The main objective of the business is to maximize its profitability. Operating business cannot have only one objective because a company needs to meet the demands of different stakeholders such as employees, consumers, creditors and shareholders among others. In terms of the stages or processes involved in an organisational sales strategy, it can be said that the primary facets involve: Preparing sales objectives Studying sales market environment Recognising the various alternatives available Assessing the alternatives and selecting the best possible one for the organisation Preparing s ales budget and forecast Formulating sales plan and gaining approval of the management Executing the sales plan with the help of appropriate human resource allocation Making an evaluation and review of the sales plan Source: (Trehan & Trehan, n.d.) There are four basic sales strategies such as account targeting, sales channel, selling and relationship, the categorization of these accounts within a targeted market for incorporating strategic approaches in the sales, through accounting groups or accounting. An organized selling procedure for each accounting targeting, sales channel, relationship and selling strategy develops effective and efficient selling procedure which is a significant in

MGR #6 Essay Example | Topics and Well Written Essays - 250 words

MGR #6 - Essay Example A prayer is a religious expression of thanks or a request for help addressed to God or an object. According to this MGR prayers are not only concerned off wellbeing of the one praying, but the will of God to be done according to his wishes. Prayers are a communication between a human being and God. It is through this communication that human have  faith that their wishes will be answered. People pray for different reasons which include blessings, healing, and guidance. My second takeaway is confession. Confessions are statements made by a group of people or a person acknowledging personal facts that the group or the person would ostensibly prefer to keep hidden. Confession is one way of repentance. The main thing that leads to confessions is when a person sin. A sin is anything that come  between  the right ways of God and a person. One of the major drives to confession is fear. It keeps us away from enjoying our freedom until we confess our sins. Another reason for confession is to seek forgiveness. A human can feel guilty after a sin and, as a result, we tend to look for forgiveness from God or other people by confessing our

Facilitating the interview process Essay Example for Free

Facilitating the interview process Essay In this essay I will evaluate each document from Harrow College Application Pack, it will include information that applicants will need to know before they applied for the job. Inside the pack, it includes welcome letter from the principal, the curriculum of Harrow College, Organization chart, policy statement, travel policy, how to fill in an application form, job description, and person specification. In the application pack, a welcome letter from the principal of Harrow College will help recruitment because the letter is written by the principal it will set the standard and it attracts applicants and also it will make a good impression to applicants knowing the principal welcoming them to apply to Harrow College even though the principal is not saying it in person but it will make the applicant more welcoming and comfortable with the College. Secondly, the letter said â€Å"Harrow College now ranks as the top FE College in West London and Hertfordshire†, this will make applicants be more interested about the job role because they want to be part of Harrow College success and want to be part of that reputation. Harrow College can improve their welcoming letter by making the applicant feel more welcoming, instead of the principal saying thank you to applicant for applying, the principal should also include staff in Harrow College, that way applicants will feel the support of everyone in Harrow College. The letter also should include some background information of Harrow College and what kind of achievements Harrow College had to attract applicants. I think the letter from the principal is important because it will show a good sign that the college is welcoming and tells the applicant small information about Harrow College. The curriculum letter will help recruitment because it shows what subjects are majored in Harrow College; it will give a chance for applicants to see what other subjects they can apply for if in the future Harrow College have any vacancies. In the curriculum letter, it has background information about Harrow it will benefit the applicant because if the applicant doesn’t live local, they can find out about Harrow area. The organization chart will help recruitment because it will help applicants know who does what and who to report to, it shows Harrow College that they are a well-organized college, also it will allow the applicant to know there are people in different department doing different task. This document also helps me when I was recruiting in John Lewis because by knowing who is the CEO of the company and who is my manager in the organisation chart, it will help me in the future that if I have any problem I know who to report to. The equality and diversity policy statement will help recruitment because it will encourage applicants with different background to apply for the role, it will give a good impression to applicants that Harrow College don’t care where the applicants are from. Harrow College can improve their equality letter by showing figures of different background of staff in Harrow College because even though the letter tells applicants they accept anyone no matter where they from but some applicants would like to see the figures of different race and sex to know Harrow College is committed to equality and diversity. How to fill in an application form will help recruitment because is a step by step instructions of filling in an application form for applicants, that way applicants wouldn’t make any mistake or miss a section out, it will benefit for Harrow College because if the applicant make a mistake in the application form, employers from Harrow College can straight away not read the rest of the application form because employers might think if the applicant can’t follow simple instructions from the application pack then they can’t follow instructions when they are employed. Job description will help in recruitment because it sets out the main purpose of the job; it shows where the job is fitted in the organization structure, and the main responsible of the job and the type of task they will need to perform, putting the right information on job description is important because if Harrow College didn’t include detailed information on teaching and related activities and general duties, then when they have recruited the applicant, the applicant might not have any experience as a lecturer, they might not be flexible e.g.: travelling to two Harrow College Campuses, to act as a personal tutor to students. If those details weren’t included in job description, then the college would be hiring someone who have no qualifications and experience and that will cause Harrow College time and money because they would have to train the applicant or hire someone again. The changes that I would make is to improve their job description is to include how many hours the applicant will need to work, is important to put that information in the job description because applicant would want to know how many hours they need to work furthermore some applicant might have a family that they need to look after or pick up their children so if Harrow College would want the applicant work long hours during the week then some applicant can’t apply because of their personal problem. Person specification will help in recruitment because it gives information to the applicant what qualifications and experience is needed if they want to apply for the job, also Harrow College has designed well information of person specification, it included a lot if skills, different qualifications, and it specify on equality and diversity because selecting the right business lecturer is important for Harrow College, if they hire someone who hasn’t got any experience or the right qualifications then the lecturer won’t be teaching right to the students then it would mean Harrow College have to waste money again to recruit another lecturer again in addition to students would fail their exam which will cause Harrow College success’s rate to drop. The changes I would make to prove their person specification is to include the location of the job the reason for that is because applicant might want to know which campuses they will be teaching in and by putting the location applicant can decide whether they want to apply because if Harrow College would want the applicant to work in both campuses then applicant can’t apply because they might not want to travel to two campuses. Also Harrow College can include another column in the person specification e.g.: essential and desirable the reason for putting another column is because in the person specification it tells the applicant what skills are needed and what Harrow College is looking for but if they made it clear by putting skills into two column then it would made it more clear and organize for the applicant. The advantage of Harrow College using their own application forms instead accepting CV because in an application form Harrow College can set as many question as they like and what type of questions they would to like to know from the applicant also they have set a limited space in the form so they would expect applicant to write only important information instead of applicant writing unnecessary information in there which will make employers not bothered to read the rest of the application form because it will make employers feel that applicants didn’t follow the instructions by reading the questions and putting relevant answers in the form. Secondly, if Harrow College accept CV instead of application form, it will waste a lot of time and money for employers to read and compare each CV instead employers can use that time to do other things e.g.: mark students work and teach furthermore because each CV have different layouts with different information it will make employers much more harder to choose the right candidate that will be suitable for the job. Thirdly, employers can already tell if the applicants is a organize person or not by their writing and also their grammar, if the applicant grammar is poor which shows a really bad impression to the employers because the job role is lecturer and if their grammar is poor that will make employers in Harrow College consider that they can’t teach properly and if they hire that applicant then the applicant wouldn’t mark the student’s work properly. In my opinion, every document in the application pack is important. If one document is missing in the application pack, the company won’t hire the right applicant but overall I think the most important document is job advert and person specification because without job advert, no one would know about the job, applicant wouldn’t know how to apply for the job and what the job is about, also job adverts are very expensive whether the business is small or big. At the end of the day, the businesses still need to pay. Often job adverts are in short detail but the advert highlights the knowledge, skills and experience that each individuals are require within each advert. Job adverts would never change because of the job role because it would always tells the summary of the job, the location and how to apply so it wouldn’t make any difference with any job role but whereas person specification with different job role it would include different information depending how important the job role is e.g.: in the application pack, Harrow College is hiring Business Lecturer, therefore person specification would have a lot of information that they would require from a applicant but if Harrow College want to recruit a reprographics assistant, the person specification wouldn’t have much responsibilities as a business lecturer so when applicant read the person specification it won’t have a lot of requirements as the business lecturer person specification.

Merry King Essay -- Globalization, Competition, Software Development

In today's commercial market environment, competition and globalization has increased dramatically. The excessive cost arising from inefficient processes and operation have been considered to be the major causes of losses to the organizations over the past several years. Several organizations, particularly larger companies, recognize the need to hedge and manage against undesired risks. Software development is presently one of the most common risk issues. Adler et.al., (1998) reveal that the software development project includes risk events that can cause damage to improving processes. Moreover, it would be an error of judgment to overlook the significant risk areas of the project as this will impair decision quality and impact massive product changes. Raz et.al., (2002) describe project risks as adverse events that can cause delays, surplus expenditure and dissatisfaction with the project outcome. Apart from this, each project varies in size, duration, uncertainty, complexity, objectives, limitations and others. In an effort to enhance the quality of procedure and minimize the risk profile, better execution and implementation will also reduce undesired performance. Adler et.al., (1998) note that there is a tendency to claim that Cleanroom approach would be more appropriate to improve the overall trustworthiness and quality assurance issues. This essay will first describe how the effects of software risks have a direct impact on day-to-day business activities. It will then define how software risk management plays an important role in coping with the project risks. In the second section, it will introduce two software risk management models namely the Software Risk Evaluation model (SRE) and Cleanroom Softw... ...able for software engineers to monitor quality control that can be scientifically verified in a formal statistical diagram. In a study, Raz et.al., (2002) point out that there is a continuing requirement for an adaptation from the different risk management techniques to the different kind of projects and the improvement of the specific devices to mitigate risk from several different type of projects. In essence, it could be said that many organizations increasingly recognize the importance of software risk management to ensure accessibility of the overall information of the project risks. What is more, Ward (2005) concludes that a company which constantly develops risk management tends to gain a competitive advantage, and it appears probable that a well-defined software risk management practice can assist to increase the company's competitive advantages as well.
