During The Past Two Decades There Has Been A Tremendous Increase In Th

During the past two decades there has been a tremendous increase in the numbers and sizes of networks. Many of the networks, however, were built using different implementations of hardware and software. As a result, many of the networks were incompatible and it became difficult for networks using different specifications to communicate with each other. To address this problem, the International Organization for Standardization (ISO) researched many network schemes. The ISO recognized that there was a need to create a network model that would help network builders implement networks that could communicate and work together (interoperability) and therefore, released the OSI reference model in 1984. This chapter explains how standards ensure greater compatibility and interoperability between various types of network technologies. In this chapter, you will learn how the OSI reference model networking scheme supports networking standards. In addition, you will see how information or data makes its way from application programs (such as spreadsheets) through a network medium (such as wires) to other application programs located on other computers on a network. As you work through this chapter, you will learn about the basic functions that occur at each layer of the OSI model, which will serve as a foundation as you begin to design, build and troubleshoot networks. The concept of layers will help you understand the action that occurs during communication from one computer to another. Shown in the Figure are questions that involve the movement of physical objects such as highway traffic, or electronic data. This motion of objects, whether it is physical or logical, is referred to as flow. There are many layers that help describe the details of the flow process. Other examples of systems that flow, are the public water system, the highway system, the postal system, and the telephone system. Now examine the Figure Comparing Networks chart. What network are you examining? What is flowing? What are the different forms of the object that is flowing? What are the rules for flow? Where does the flow occur? The networks listed in this chart give you more analogies to help you understand computer networks. Another example of how you might use the concept of layers to analyze an everyday subject is to examine human conversation. When you create an idea that you wish to communicate to another person, the first thing you do is choose how you want to express that idea, then you decide how to properly communicate it, and finally, you actually deliver the idea. Imagine a young boy seated at one end of a very long dinner table. On the other end of the table, quite a distance away, sits the young boy's grandmother. The youngster speaks English. The grandmother prefers to speak Spanish. The table has been set with a wonderful meal that the grandmother has prepared. Suddenly the young boy shouts at the top of his lungs, Hey, you! Give me the rice! and reaches across the table to grab it. In most places, this action is considered quite rude. What should the young boy have done to communicate his wishes in an acceptable manner? To help you find the solution to this question, analyze the communication process by using layers. First there is the idea ? the young boy wants rice; then there is the representation of the idea? spoken English (instead of Spanish); next is the method of delivery ? Hey, you; and finally, the medium ? shouting (sound) and grabbing (physical action) across the table for the rice. From this group of four layers, you can see that three of them prevent the young boy from communicating his idea in an appropriate/acceptable manner. The first layer (the idea) is acceptable. The second layer (representation), using spoken English instead of Spanish, and the third layer (delivery), demanding instead of a politely requesting, most definitely do not follow acceptable social protocol. The fourth layer (medium), shouting and grabbing from the table rather than politely requesting assistance from another person seated nearby, is unacceptable behavior in most any social situation. By analyzing this interaction in terms of layers you can understand more clearly some of the problems of communication in both humans or computers, and how you might solve them. As you learned in chapter 1, the most basic level of computer information consists of binary digits, or bits (0s and 1s). Computers that send one or two bits of information, however, would not be very useful, so other groupings

About Marcel Breuer, Bauhaus Architect and Designer

About Marcel Breuer, Bauhaus Architect and Designer You may recognize Marcel Breuers Wassily chair, but you know Breuers Cesca, the bouncy metal tubular dining room chair with the (often fake plastic) cane seat and back. An original B32 model is in the collection of the Museum of Modern Art in New York City Even today, you can buy them, because Breuer never took a patent on the design. Marcel Breuer was a Hungarian designer and architect who moved with and beyond the Bauhaus school of design. His steel tube furniture brought 20th century modernism to the masses, but his bold use of precast concrete enabled large, modern buildings to be built under budget.

Media Globalisation Essay Example | Topics and Well Written Essays - 1000 words

Media Globalisation - Essay Example The usage of facts and figures has been excellent here and the writer has not stepped back in accepting the fact that the Japanese television industry is highly influenced by the American industry. Then the trend of the Japanese television industry has been explained. The trend shifted towards more television shows from movies due to the huge boom in the popularity of television serials (Chun, 2006, p.368). Though American influence was present but since 1980s except some television serials imported from America others haven't fare well in Japan. American movie culture is still quite famous and people enjoy watching movies produced in Hollywood. The fame of television series' led to a decline in the movie audience and this lead to more filmmakers turning towards television industry, which only led to an increase in the popularity of television serials (Blumenthal et al, 2006, p.592). The importance given to a television serial is on the basis of its local touch that is the viewers do n't really care if the serial is a copy from some other television industry what they really care about is the 'Japanese odor' in the serial. The solution to this situation was to import television shows from different industries and run them in Japan adding a local touch, which proved to be quite successful in the end. One of the example of such television show mentioned by the writer here is 'Who wants to be a millionaire'. The success rate of this show in Japan was huge though it was an imported show but the cultural touch relevant to Japan that was given to it proved outstanding. The Japanese version is mostly the same as of the version running in Britain but with some amendments like the appearance of celebrities as challengers. The draw back that this article has here is the mentioning of an international television show being popular when the writer himself mentioned that locally produced television serials are more liked by Japanese people. To level out this effect the write r than discusses a show that was imported from America but failed to make its mark in the Japanese television industry, the name of the program is 'Survivor'. The cultural products that Japan exports are called culturally odorless as they do not depict any cultural theme of the country. It is in this context that the Japanese is called Mukokuseki which means something or someone lacking any nationality. Now the writer directs his attention towards the television serials that are being exported from Japan. The interesting fact here that the writer mentions is the number of programs being exported by Japan is far more than imported. The writer also discusses the point raised by many critics who say that the largest shareholder of Japanese exported programs is animation and cartoons. This point is further supported by the fact that the writer presents, the fact is that animated programs produced in Japanese only consist of 1 percent of the total animated programs being produced by Japan confirming that they are being produced to export. The animation producers do not portray Japanese culture in the cartoons and games because they think that this is better for these programs as they are for export. (Gomery & Hockley, 2006, p.142) By glocalizing, the Japanese are buying highly prominent program formats in the West and then localizing them according to the tastes of the Japanese. The author points that the format business is considered as a highly effective and

The terms leadership and management are often used interchangeably Essay

The terms leadership and management are often used interchangeably where some writers argued to clear distinction between management and leadership whether is it simply a function of management - Essay Example The research on the literature published on the specific field proved that a series of differences exist between leadership and management. This phenomenon is common in all industrial sectors, including the airline industry on which this paper focuses. Researchers have used different criteria in order to describe leadership and management – as developed in modern organizations. In accordance with Nurmi et al. (1997) the leadership can be characterized as ‘an influencing force’ (Nurmi et al., 1997, p.135) within the organization. It is at this point that leadership is differentiated by management; more specifically, it is noted that ‘a manager can be appointed while leadership can be earned’ (Nurmi et al., 1997, p.135). Moreover, Weihrich (2007) states that leadership can be defined as ‘the art or process of influencing people so that they will strive willingly toward the achievement of group goals’ (Weihrich, 2007, p.347). In accordance with the above views, leaders need to have increased skills compared to managers. The latter may be appropriately educated but may not be charismatic enough in order to be leaders. In other words, leadership refers to a combination of technical and inte rpersonal skills while management can be related to specific educational and professional background. In practice, the potential limitation of management towards the leadership may not be identified. This is the case, for instance, where the manager has not to act as a leader, a phenomenon common in mid-managerial positions. A similar approach is adopted in the study developed by the Pergamon Flexible Learning (2007); in the above study it is noted that management is differentiated from leadership at the following points: a) the manager focuses on the administration of various organizational activities while the leader tries to promote innovation across the organization, b) the manager focuses on

Financial Aid and its Affect on Grade Point Average Research Proposal

Financial Aid and its Affect on Grade Point Average - Research Proposal Example Using an exploratory research design, the researcher will investigate whether merit-based financial support to the students has any considerable effect on the class and exam performances of students or not. Problem Statement The problem statement for the research paper is: "Financial aid plays a significant role in improving the grade point average of first year students of both private and public higher education institutes". Conceptual Framework Aim of the Research Merit-based financial aid programs help both poor and academically brilliant students to study in prestigious institutes and prove their academic skills and potential. Such schemes not only provide a chance for the students with high academic potential to get higher education but also play a valuable role in improving overall class grade point average. The researcher believes that when students having academic brilliance will get a chance to study in high quality educational settings, they will also provide academic supp ort to other students which will consequently increase their GPAs as well. Therefore, the research in this area holds great importance. The aim of this research is to identify whether financial aid programs play a considerable role in improving the academic performances of students or not. The researcher will also examine the structure of financial aid being provided to students in both public and private institutes. The researcher will examine the data collected from 3 public and 2 private institutes and will analyze them to come up with the final stand point. Literature Review There has been some research in the area of student retention and higher education access through the implementation of financial aid programs in higher education institutes. According to Alon, the results of previous researches in this field provided all sorts of effects, which include positive, negative, and mixed (122). However, positive effects overshadow the negative effects as provided by the research. The main reason behind positive effects as provided by Alon in this regard is that students get the time to concentrate on studies instead of finding ways to earn money. A recent research aimed at identifying the effects of financial aid programs found that the retention rate of aid recipients is usually high which may be because of the fact that students like to be the part of the institute which provide them with financial support during the whole duration of the course (Kuh et al. 545). As Curs and Harper state, â€Å"merit-based financial aid has a positive and significant effect on first-year collegiate grade point average† (627). Other researchers studying the effects of both need-based and merit-based financial aid programs have also found that merit-based programs have more significant effects as compared to the need-based programs (Stater 782). Merit-based financial aid programs are also associated with a number of positive outcomes, such as high rate of retention, increased motivation among students, creation of a collaborative learning environment, completion of the study program, and increased academic competition among students (Dynarski 285). Methodology The researcher will perform a deep analysis of the data gathered from 5 public and private

Exploring Sport Opportunities for Disabled

Exploring Sport Opportunities for Disabled Exploring sport opportunities for young athletes with different abilities Abstract The aim of the study is to develop a new terminology from the negative term of â€Å"disability† and to try and hava an inclusive system during physical activities in schools. In addition is tries to highlight the importance of having more inclusive sport opportunities for everyone and to improve the self-esteem of people with different abilities. In Malta few athletes with different abilities have the opportunity to be included into sport activities. In schools there is not much time allocated for persons with disability both during physical education lessons and also during break time. As the athlete with different abilities starts thinking seriously of sport activities he encounters a lot of mishaps primarily the over-protection from parents and organisers. In addition he also faces the disadvantage of the lack of sport opportunities for him. This reason led the researcher to investigate what is really going on, both during childhood when it comes to school activities i.e. physical education lessons, and at later later stage during adolescence and adulthood when it comes to sport opportunities offered by society. This study is made up of five chapters which start from the history and defenition of disability and ends up with the guidelines to a way forward. Introduction The aims of the study are: To try and transit from a terminology that might sound negative â€Å"disability† to a better word â€Å"Different abilities† To try and have an inclusive system during physical education in both primary and secondary schools To have more sport opportunities which include everyone both for leisure and also on a professional level To strengthen the self-esteem of persons with different abilities The study is made up of five chapters. Chapter 2 tackles the history of disability and sports. An overview of the study background and key terms used within the study investigation are also provided. Chapter 2 gives an overview of some basic terms and general knowledge related to disability and sports which give a better understanding of the aims of the study. An evaulation and illustrations from experts regarding sport and disability sectors also follow. Chapter 3 investigates the approach taken and the processes involved in achieving the dissertation objectives. Details of the sources used as well as a description of the method used to collect the primary and secondary research data are also provided. The study concludes with an evaluation of the achieved results in the previous section. The conclusions derived state the opportunities available and what can be really done to enhance further inclusion into sport for persons with different abilities, compared to the literature review findings. A study critique concludes the dissertation. CHAPTER TWO: History of disability 1.0 Introduction 1.1 History People with different abilities better known in society as people with a disability have always been in existence. For many different reasons they have become more present in the twenty first century than before. About ten percent of the population is considered to have different abilities and the parliament directives of the late twentieth century improved the accessibility and availability of services and facilities for this group which is considered to be the largest minority group in society. This resulted in more individuals with different abilities going along more easily with their daily living. These people are being more recognized in society even in sport. Athletes with different abilities have been participating since at least the last hundred years. However it has only been from recent times that these athletes started receiving the appreciation that they merit and have also been recognized as athletes. The roots of the link between sport and disability to disability sport started primarily during the 20th century and developed into a new movement. This movement has developed up to the point so as to include the complexity of its members and also restructuring of its aims and visibility. Athletic opportunities have expanded so as to have individual accomplishments of athletes with different abilities. These overlooked and unseen sportspersons are gaining increased recognition firstly as athletes and above all as humans with different abilities. Exceptional performances by top athletes with different abilities are purely seconds or tenths of seconds behind those of top able-bodied athletes, in sport disciplines like downhill skiing and swimming. Athletes with bi-lateral leg amputations finished a hundred metre race in 10.85 seconds and others with less severe impairments finished in even less time. A top male wheelchair athlete finishedd a marathon at an average of 3.5 minutes per mile and managed to complete marathons in almost ninety minutes or less, while a female wheelchair athlete did the same marathon in an hour and forty nine minutes. 1.2 Definition of Disability The terms functioning and disability must be defined clearly in order to understand the interrelationship between functioning and disability. The term â€Å"functioning† describes the functions and structures of the body. It helps to grasp an individual’s interaction with a health condition and the environmental and personal contexts. Disability is viewed as the result of the interaction between individual functioning and the environment when linked with a health condition. The level of difficulty is highly dependent on the degree of functional autonomy and independence of persons living with disabilities, be they sensory, physical or mental. Accordingly, functionality is defined as the ability to perform those activities necessary to achieve well-being through interaction between the biological, the psychological (cognitive and affective) and the social spheres (Sanhueza Parra, 2005), and whose loss entails the risk of disability and dependence. Care thus avoids what M orris (2001) terms the social construct of dependence, which negates the individual. For people with disabilities, respecting their right to care gives them access to assistance from others and to essential technical aids, and a physical and social environment that is adapted to their particular impairment. Following the environmental approach taken by WHO, functional autonomy may therefore be defined as the ability to perform functions related to daily life, such as those activities necessary to achieve well-being through appropriate interaction between the biological, the psychological (cognitive and affective) and the social. This enables the individual to live in the community with little or no help from others, albeit with assistive technology. (United Nations, 2012 pg 183) Very often, lay and, sometimes, professional people do not seem to make a distinction between such terms as Impairments, Dis-abilities, Handicaps. These are often taken to mean one and the same thing. But this is wrong. The World Health Organisation, in 1980, published a manual titled International Clasification of Impairments, Disabilities and Handicaps, whereby, three distinct and independent were proposed, each relating to a different plane experience. †¦ Disability is â€Å"any restriction or lack (resulting from an impairment) of ability to perform an activity in the manner or within the range considered normal for a human being†. It represents objectification of an impairment and, as such, reflects disturbance at the level of the person. †¦ Disability is concerned with abilities in the form of activities and behaviour a person`s body is expected to carry out as essential components of every day life, such as represented by tasks, skills, and behaviour. Disability signifies a departure from the normal in so far as the performance of the individual is concerned as opposed to that of the organ or mechanism. ( Troisi, 1992 pg 3 4) CHAPTER THREE:  LITERATURE REVIEW Young people are often seen as challenges to most people in society. This is exactly what the article â€Å"Positive Youth Development through Sport† edited by Nicholas L. Holt declares. According to Holt speaking from the perspective of Positive Youth Development (PYD), argues that young people are frequently pointed out as problems in society waiting to be solved. However young people are understood to embody potential, awaiting development. Holt points out that sport itself provides a developmental context that has been associated with PYD, but sport on its own does not lead to PYD. In fact he points out that in some environments there are instances when negative outcomes arise from sport participation. Thus it is the manner in which sport is structured and delivered to children that influences their development. Nicholas Holt quotes Larson and expresses that, organized activities can provide youth with opportunities to experience positive development. He states that sport is the most popular organized activity into which youth engage (Larson and Verma 1999). Both theory and research point out the importance of structural out-of-school-time (OST) activities as important assets in the positive development of youth (Mahoney et al. 2005). Holt in his article says that youth participation in organized sports has been linked to indicators of adolescent’s physical, social, psychological, and achievement related behaviour and development. Researchers (Barber et al. 2001: Eccles et al. 2003) found that, in comparison to non-participants, youth who participate in sport enjoyed attending school more, received more frequent educational and occupational support, had higher academic performance, longer periods of tertiary education by age 25, and attained a job at age 24 that offered autonomy and a promising future. Although there where diverse research findings regarding the relationsip of sport participation and alcohol use, some found a relationship between sport participation and a lower level of alcohol use (Peretti-Watel et al 2003). Other findings indicated a positive relationship between sport participation and alcohol use. Sport participation has also been consistently linked to a lower use of cigarettes, mariju ana, cocaine, and ‘other drugs’ (Page et al 1998). Furthermore it was also related to lower rates of depression and lower incidence of suicidal behaviour. Researchers and youth advocates have proposed important benefits of sports involvement. However, to date, little research has accounted for the dynamic ways in which youth spend their free time. A book entitled No one`s perfect, tells the story of a Japanese Boy who despite being born without arms and limbs he managed to do it his way into sport. This Japanese little boy, named Ototake, came home from school one day and told his parents he had signed up to play basketball. In contrary to other parents who would be delighted to such a request, they where shocked. Oto was born with no arms and no legs. Despite his disability, this extraordinary young man has always proven a hard-worker, rich in versatility and with an upbeat approach to life. This positivity served him as valuable as limbs. No Ones Perfect is his true account of how he slam-dunked one challenge after another, including basketball. Ototake says that thanks to having short arms and legs plus a wheelchair, he was a winner in the popularity department. He found himself always the centre of a circle of friends. With time the typical willfulness of an only child began to kick in. Ototake maintains that at first break time, when everyone would be playing tag in the playground, or physical education lessons, were dead boring for him since with his power wheelchair he could not keep up with his friends. Thus he usually yelled for them to come and play with him: â€Å"If you want to play in the sandbox, follow me!† Strangely enough, the kids who had been happily chasing one another a short while before would all troop after the wheelchair to the sandbox. Ototake highlights that looking back to school days, most people with disabilities admit that recess was the worst part of their day. This is that particular time when ordinary children, unless they are real bookworms, would enjoy. The main reason is that for disabled kids the forty five to fifty minutes of a class period pass quickly enough while they sit quietly in their seat, but during breaks, when they can`t join in the fun their classmates, they feel greater sense of isolation so they can`t wait for recess to be over.

Long Range Effects of the Internet on Society :: Exploratory Essays Research Papers

Long Range Effects of the Internet on Society Whenever any major development in society is conceived, such as when phoneswere introduced, problems ensue. The internet, because of it's modern nature is not really well dealt with when it comes to existing legislation. The solutions to anyproblems with the 'net are so complex that any legislation that could ensue might threatento infringe upon the rights and privileges that Americans enjoy today. "Virtualcommunities could help citizens revitalize democracy, or they could be luring us into anattractively packaged substitute for democratic discourse."(Rheingold 276) "What if thehopes for a quick technological fix of what is wrong with democracy constitute nothingmore than another way to distract the attention of the suckers while the big boys divideup the power and the loot."(Rheingold 278) "All too often the regulatory and policymechanisms of government have been subverted by the industries they exist to control. Although this takeover has not usually been intended by the formulators of thesemechanisms or the laws setting up agencies, many factors lead to this corporatedomination when the regulation involves a rapidly changing area."(Hiltz 445) Accordingto Rheingold, everything is eventually somehow commodified. "The First Amendmentof the Constitution's Bill of Rights protects the citizens from government interference intheir communications-the rights of speech, press, and assembly are communicationrights. Without those rights, there is no public sphere. Ask any citizen of Prague, Budapest, or Moscow."(Rheingold 282) "Just as the ability to read and write and freelycommunicate gives power to communicate gives power to citizens that protects themfrom the powers of the state, the ability to surveil, to invade the citizen's privacy, givesthe state the power to confuse, coerce and control citizens. Uneducated citizens cannotrule themselves, but tyrannies can control even educated populations, givensophisticated means of surveillance."(Rheingold 289) "This assault on privacy, invisibleto most, takes place in the broad daylight of everyday life. The weapons are cashregisters and credit cards. When Big Brother arrives, don't be surprised if he looks like agrocery clerk, because privacy has been turning into a commodity, courtesy of betterand better information networks, for years."(Rheingold 291) "The most insidious attackson our rights to a reasonable degree of privacy might come not from a politicaldictatorship but from the marketplace.

Philosophy- Rationalism and Empiricism Essay

Immanuel Kant found the way to put subjective and objective perspectives together as part of the human transcendental structure. The idea of subjective truth comes from Rene Descartes and his vision on rationalism based on innate ideas that allow people to appreciate what they see in order to reach a conclusion. Secondly, we have John Locke’s idea of objective truth based on a blank state of mind and a phenomenon that allows people to appreciate their reality by relying on experiences with any object, human, place or something else. Descartes and Locke rejected the possibility of bringing these two elements together for a better understanding. Since both focused on what people see through their eyes and their mind process, without considering the importance of the physical nature, Kant argued that they both should work together in order to understand the physical nature of different things. Kant focused on the conscious mental state which explains the importance of both of these elements together. Thomas Nagel highlighted Kant’s perspective and argued that subjective phenomenon’s are linked to single points of view that the objective theory will never be able to abandon. If a person separates them from each other there will be no idea of how something could be true. Since we live in a society with different perspectives, truth is what everyone looks for in order to draw their own conclusions. Nagel argued that having personal experience is enough to have the necessary material for imagination. For example, Nagel offered a metaphor about a bat, in which he suggest the use of imagination to ask ourselves what would be like for us to behave as the bat behaves. It’s clear that Nagel relies on Aristotle’s vision of reality because his realism on subjectivity creates a belief in the existence of facts over the concepts that we create as humans. Although there are facts that people will never comprehend, there is a possibility that through a combination of both people can find the truth of things that they can’t understand. According to Nagel, there is no difference between mental and physical events because there are experiences in which people process things to reach a conclusion. People have the ability to perceive and behave and they both come along together. On the other side, Donald Davidson argued that mental events have physical causes and that we have reason to believe this even though people don’t know if there is a general psychophysical theory. But, what about non-intentional events? Nagel argued that his argument only applies to intentional mental events without considering that as humans have reasons to believe that sensations are physical processes as well. Physical processes don’t have the necessity to look for answers of how something happened. Finally, Kant’s theory argues that our experiences are significant since they can’t be the same because people’s different states of mind, but as human beings it’s important to be subjective to appreciate different phenomenon’s around them. Kant’s made these two perspectives dependent from each other, without leaving any gap in which they both could separate by any chance.

Catalysts Definition and How They Work

Catalysts Definition and How They Work A catalyst is a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed. This process is called catalysis. A catalyst is not consumed by the reaction and it may participate in multiple reactions at a time. The only difference between a catalyzed reaction and an uncatalyzed reaction is that the activation energy is different. There is no effect on the energy of the reactants or the products. The ΔH for the reactions is the same.​ How Catalysts Work Catalysts permit an alternate mechanism for the reactants to become products, with a lower activation energy and different transition state. A catalyst may allow a reaction to proceed at a lower temperature or increase  the reaction rate  or selectivity. Catalysts often react with reactants to form intermediates that eventually yield the same reaction products and regenerate the catalyst. Note that the catalyst may be consumed during one of the intermediate steps, but it will be created again before the reaction is completed. Positive and Negative Catalysts (Inhibitors) Usually when someone refers to a catalyst, they mean a positive catalyst, which is a catalyst that  speeds up the rate of a chemical reaction by lowering its activation energy. There are also negative catalysts or inhibitors, which slow the rate of a chemical reaction or make it less likely to occur. Promoters and Catalytic Poisons A promoter is a substance that increases the activity of a catalyst. A catalytic poison is a substance that inactivates a catalyst. Catalysts in Action Enzymes are reaction-specific biological catalysts. They react with a substrate to form an unstable intermediate compound. For example, carbonic anhydrase catalyzes the reaction:H2CO3(aq) ⇆ H2O(l) CO2(aq)The enzyme allows the reaction to reach equilibrium more quickly. In the case of this reaction, the enzyme makes it possible for carbon dioxide to diffuse out of blood and into the lungs so it can be exhaled.Potassium permanganate is a catalyst for the decomposition of hydrogen peroxide into oxygen gas and water. Adding potassium permanganate increases the temperature of the reaction and its rate.Several transition metals can act as catalysts. A good example of platinum in the catalytic converter of an automobile. The catalyst makes it possible to turn toxic carbon monoxide into less toxic carbon dioxide. This is an example of heterogeneous catalysis.A classic example of a reaction that doesnt proceed at an appreciable rate until a catalyst is added is that between hydrogen g as and oxygen gas. If you mix the two gases together, nothing much happens. However, if you add heat from a lighted match or a spark, you overcome the activation energy to get the reaction started. In this reaction, the two gases react to produce water (explosively).H2 O2 ↔ H2O The combustion reaction is similar. For example, when you burn a candle, you overcome the activation energy by applying heat. Once the reaction starts, heat released from the reaction overcomes the activation energy needed to allow it to proceed.

Is it Okay to Split an Infinitive Can I start a sentence with And

Is it Okay to Split an Infinitive Can I start a sentence with And The following is some basic writing help that answers your questions about when its okay to split an infinitive, whether to start sentences with â€Å"And† or â€Å"But,† and whether it’s okay to use a singular â€Å"they.† Here are the grammar rules and non-rules that tend to be confusing to many writers (and readers): Is it okay to split an infinitive? Yes, it’s okay to occasionally split an infinitive! But if you can be graceful, it’s better not to split it. â€Å"It’s okay to split an infinitive occasionally† would pose a lower risk of annoying your readers than the first sentence above, which, as you may have noticed, contains a split infinitive. Can I start a sentence with And or But? Yes, it’s okay to start sentences with â€Å"And† or â€Å"But.† But don’t overdo it. Is it okay to use they as a pronoun for one person? I used to be adamant that â€Å"they† is not an appropriate reference to a single person! But even I sometimes use it now and allow my clients to use it too. While there are often workarounds for using the singular â€Å"they,† they are often awkward. There’s a Can I use â€Å"this† without a reference? This is not recommended. The question always to ask yourself (or – see #1 – to always ask yourself) is, â€Å"This WHAT?† and tell us what the WHAT is. Rather than say â€Å"This is not recommended,† try â€Å"This construction is not recommended.†Ã‚  Otherwise your readers will not know what â€Å"this† refers to. Shall I go into whether it’s okay to end a sentence with a preposition?  Let’s save that one for another day.

Biology Essay Example | Topics and Well Written Essays - 500 words - 10

Biology - Essay Example All living things are composed of one (unicellular) or more (multicellular) cells. All the cells gather energy and utilize energy for growth, reproduction, repairing processes etc. Many different types of cells perform different jobs and together co-ordinate and keep living beings alive. Unicellular (one celled) organisms are bacteria and paramecium, while fungi, plants and animals are multicellular (many cells). The living things are classified into prokaryotes and eukaryotes. Bacterial cells are prokaryotes with simple structure without complex organelle system. Figure 1.A (1) shows prokaryotic cell structure of unicellular bacteria and Figure 1. B shows many bacterial cells. Bacteria are the smallest organism on our planet. Plant cells (Figure 2) (2) form plants. Animal cells (Figure 3) (3) form animals. The plants and animal cells are eukaryotes having larger size than eukaryotes and have complex organelle system. Cells put together form tissues. Tissues form organs. The organs put together form organ system. The organ systems put together make plants and animals. The organelle nucleus in the eukaryotic cell accommodates deoxyribose nucleic acid (DNA) which is a blueprint of our life. The DNA houses the intelligence needed to determine the characteristic shape (structure) and job (function) of all living creatures. We get this DNA from our parents which decides our physical make up, our intelligence, and it reflects our personality. DNA of a cell decides the characteristic role of that cell it has to play in our body. This double helix DNA is like a spiral staircase. DNA can be extracted from any living things and can be seen in a test tube with naked eye in the form of long ropy strings. This DNA is made up of four nucleotides A, T, C and G (Figure 4) (4). The various permutations and combinations of these nucleotides differentiate each living being. It decides who and how we should be. The human beings

FMEA - Assignment Example It just happened as I predicted. A cold icy wind was whipping my fur while my heart was beating heavy like the â€Å"tum tum† drums of West Africa. My whiskers started to shiver like a twig in the middle of a storm, as snowflakes were sticking on my eyelashes. It was indeed cold like hell. The night snowstorm seemed to have fought the whole Wednesday night, causing several accidents that messed up traffic. Across the state, Highway Patrol troopers were seen in response to several crashes. Furthermore, as I sloped down the road, I witnessed casualties of the act of god. Two drivers were killed in the wee hours when their cars slid off snow-covered roads and struck trees. According to the running gossip around the scene, when I stopped to witness, the driver was killed when his car hit an embankment on before hitting a tree. In both cases, troopers concluded that the drivers had exceeded safe speeds for the slippery roadways. School buses were stuck in traffic the whole night until morning. Moreover, the streets were clogged as cars became trapped in gridlock because of the snow that ruled the highways. Indeed, it was a situation of life and death. In addition, I almost had an accident; my car was stuck at the bottom of a sloping corner. I decided to ditch my car after it spun out, trudged through the snow, and make it to school safely. Normally in 30 minutes, I could have driven to School; however it took me two hours, of which was a hilarious adventure. That snowstorm caught the populace off guard, including forecasters. The state Department of Transportation had been poised to spray brine on Triangle roads during the day Monday, in advance of snowfall that was not expected until the Tuesday night. However, the forecasts were all incorrect, and the snow came in a lot earlier at night. The snowstorm that occurred that night was indeed terrible. It reminds me of a story
