Chapter II Review of Related Literature and Studies Related Literature Polystyrene Commonly known as Styrofoam that is one of the most widely used type of plastics. It is a strong plastic created from erethylene and benzine that can be injected, extruded, or blow molded; making it a very useful and versatile manufacturing material. It is also a rigid, transparent thermoplastic, which is present in solid or glassy state at normal temperature. But, when heated above its glass transition temperature, it turns into a form that flows and can be easily used for molding and extrusion. It becomes solid again when it cools off. This property of polystyrene is used for casting it into molds with fine detail. Pure polystyrene polymer is colorless†¦show more content†¦Oyster-shell is entirely composed of CaCO3 (approximately 96%) and other minerals of trivial amount. Various oyster-shells due to sources and individual characteristics are almost similar in the chemical composition. The mineral phase of calcium carbonate turns out to be calcite. Related Studies Foreign Xu, Yi; Jiang, Linhua; Xu, Jinxia; Li, Yang (2012) pointed out that mix proportion parameters of expanded polystyrene (EPS) lightweight aggregate concrete are analyzed by using Taguchis approach. The density, compressive strength and stress-strain behavior were tested. The optimal mixture of EPS lightweight aggregate concrete was selected among experiments under consideration to manufacture the lightweight hollow bricks. The results show that EPS dosage has the most significant effect on compressive strength of EPS lightweight aggregate concrete, then water and cement ratio, while the content of cement and sand ratio play a comparatively less important part. The relationship between density and compressive strength of EPS lightweight aggregate concrete is proposed as [f.sub.c] = 2.43 x [[gamma].sup.2.997] x [10.sup.-9]. The legitimacy of the use of EPS lightweight bricks made by EPS lightweight aggregate concrete is confirmed. According to the study of Sohrab Veiseh1 and Ali A. Yousefi2 (2003) the heavy weight of bricks accounts for the great mass of construction and thus causes more vulnerability against earthquake forces.

The impact of knowledge management in sustainable Development in

Essays on The impact of knowledge management in sustainable Development in Pakistan (Applied study in Pakistan) Thesis Proposal Knowledge Management in Pakistan Knowledge management is the skill of coming up with ideas, sharing them and puttingthem into use. There have been many contributors to the well being of knowledge in Pakistan; all were geared to ensure that the goal of producing a knowledgeable society is realized. Therefore, societies were formed with the help of different individuals like professors, students’ teachers and other academicians. This proposal will examine the measures used in promoting knowledge, how knowledge is transferred from one sector to another in Pakistan’s economy, advantages of knowledge management to Pakistan’s economy, challenges faced by Pakistan in managing its knowledge. Introduction Pakistan’s knowledge is mainly promoted through education; during its independence, the quality of education provided in this country was very poor. Most of its population was comprised of illiterate individuals. Currently the country has tried to come up with strategies through which its population can get access to education regardless of gender and age. Adults’ education has been highly encouraged compared to independent period. This has been done through allocation of more resources to education and trying to improve its system of education. Educational systems are divided into five categories. Each group is comprised of a different stage in personality that ensure swift flow of information from one level to another manage each level (king 32). Genders issues have addressed in Pakistan’s educational systems. Both men and women are given equal chances in accessing education and in the job market competence is the main factor to consider when deploying individ uals in the field market. Knowledge management has helped in the conservation of Pakistan’s environment and in the running of various organizations that greatly contributes to its economy. Allocation of resource and other amenities is done through acquisition of knowledge management. Therefore, a conducive environment is always encouraged for the sake of gaining knowledge in different institutions and organization (king 75). Government tries to provide quality education by providing resources and revising the curriculum when necessary. Business organizations provide a friendly environment by encouraging cooperation among its workers. Innovation is to be encouraged for the sake of being competitive in the business world Literature review Knowledge management has been described as a fundamental aspect to the success and development of any organization or nation that wants to compete favorably in the business market. Some scholars argue that technology is very important in transferring knowledge. According to king (83) it is through this technology that both workers and clients share different ideas. This is to mean Pakistan’s success in managing its knowledge will highly depend on its technological standards. In business, technology should be applied in promoting efficient communication; this also helps in faster transfer of information from one individual to another. Other reviewers argue that success of knowledge management depends on individual’s ability and the general systems of management. Systems of management have to be efficient to realize success; this is to say the flow of information from one level to another have to be good if not perfect. A study conducted by King (93) on individuality, it reveals that individuals’ skill is another aspect necessary in managing knowledge. Workers for instance should have relevant skills to the field they are dealing with. Pakistan’s has tried to improve its systems of education to realize the goal of making its public knowledgeable. It has been pointed out that knowledge management comes with its challenges that may otherwise impact negatively to the growth of an organization. It is difficult to ensure that all individuals at work place master and maintain the skill of knowledge management. This is due to cultural differences that at the work place, people have different beliefs about different things there cultural differences might conflict with the organizations goal. Methodology Knowledge management in Pakistan entirely depends on the entire society for its success. There are important pillars to the success of knowledge management; these are people, processes that are undertaken by organization, and different practices carried out in an organization. People will help in bringing about change and integrating different cultures. The same People are held in seeing to it that the knowledge management plan succeeds in any organization so long they put in mind, Processes are rules that are used in governing an organization (king 112). There are four stages used in knowledge management, one is strategy. Pakistan has put down different strategies that act as a guideline to its success for instance; it has a strategy of providing an enabling environment for all. Planning is another component necessary in knowledge management, in every business or plan one has to identify target market. Carrying out of thorough assessments in an organization is an important aspect. Execution is the third stage in knowledge management, in execution individuals are involved in the process of laying down knowledge management framework. Quality of the knowledge being offered is very necessary for instance, any organization interested in participating in a healthy business competition have to focus on the quality of the knowledge for it greatly affects the wellbeing of their business. Finally improvement in knowledge management, changes should always be implemented where necessary in knowledge management to promote to its quality. Findings Due to adoption of knowledge, management by Pakistan there has been great improvement in different sectors. Education has greatly improved where most people are now well-educated compared to earlier period. Economically Pakistan has improved due to the consistency that it has shown in the market. Businesses have achieved profitability from this skill of knowledge management (king 205). On the other hand, Pakistan has faced great challenges in integrating knowledge management in its economy due to different reasons. One being the fact that Pakistan is a developing it suffers financial setbacks in funding for technology that promotes faster flow of information in an organization. Diversity in culture that exists in Pakistan is also a problem in knowledge management. Culture of a particular organization highly contributes to failure of knowledge management, this framework might fail to work if at all the culture of an organization does not encourage learning new experiences and lack of flexibility. Motivation is another challenge for implementation of knowledge management. Not all workers are motivated to share different ideas with their fellow colleagues. This is because some individuals do not see the value of knowledge management (king 312). Recommendations (conclusion) Knowledge management as discussed is an important element to the growth of both nations and organisations. Therefore should be promoted at all cost. The challenges faced by knowledge management can be dealt with through motivation of workers; they are to be taught on the usefulness of knowledge management. Workers should be motivated to share different ideas with their fellow workers and finally an organizations culture should be geared towards learning new experiences. Work cited King, William R.

Television Is A Pervasive And Complex Part Of Childrens Lives, There Essay Example For Students

Television Is A Pervasive And Complex Part Of Childrens Lives, There Essay Television is a pervasive and complex part of childrens lives, there are many factors that affect how much and what they view. In the essay ?Teaching as an Amusing Activity? (1987), Neil Postman argues television conditions us to tolerate visually entertaining material measured out in chunks at a time. He explains the ways in which the media is changing the way our children are learning. Neil Postman starts off by explaining how television is being used as an attractive and seductive medium to make children to like school with shows such as Sesame Street. He describes how in a classroom setting allows the student to participate in asking questions and being interactive, while television lures the children with stimulating, colourful and creative images. Neil Postman than compares the difference in learning behaviours between the classroom setting and sitting in front of the television, which is the problem that is facing America today. Television does not encourage children to go to school but also affects their cognitive and social development. Neil Postman continues on with his idea on how children should learn. It is not what they are learning, since television shows can all be educational, it is how you learn it that is important. By watching television, the children are only expected to play a viewer role, while not realizing the familiarity of their role as a student in a classroom. This is leading American culture in the process of converting their culture from a word-centered to an image-centered society. Television is more and more becoming a curriculum as pointed out by Postman. It influences, warps and manipulates the young minds of children into believing that education is entertainment. Postman(1985) states that there are three basic commandments that educational television provides (pgs.147,148). The first one is ?Thou shalt have no prerequisites.? It means that the viewer does not have to watch a previous episode or need to watch it from the start to finish. One can just jump in anytime and still understand it. The second commandment is ?Thou shalt induce no perplexity.? If the show becomes confusing and the viewer doesnt understand, one can simply just change the channel. The final commandment is ?Thou shalt avoid exposition like the ten plagues visited upon Egypt.? In this Postman means that it is not the aim of television to try to explain something, which can be done by books, but rather through entertainment in ways like story telling with creative images and sound effects . Neil Postman has made it very clear of what television is doing to the educational system. It is taking away the traditional way of classroom learning, of how to interact with other people and respecting your elders. Television shows such as Sesame Street did not teach one those things, but it did teach children letters, words, numbers, classification and other skills considered to be important for school success. I agree with Postman that television as a teaching device is not all that great, also with its entertainment programs only encourages people to love television more, but it also depends on the viewer. Television is like a drug. It is up to the viewer if he/she wants more of it, how much resistance they are willing to provide. As stated by the author, more and more educational institutions are switching over to television as a form of teaching. Some things that are found in text books might never be able to be expressed on a screen, but images of solid objects and the sound they might produce can. Young children like moving pictures such as videos over still pictures found in books as it is more entertaining, which leads back to the same question of television being more for entertainment purposes. But that depends on ones views, some may find it as informative, others boring. .ud505fc7159f42079c114542bd089bdc2 , .ud505fc7159f42079c114542bd089bdc2 .postImageUrl , .ud505fc7159f42079c114542bd089bdc2 .centered-text-area { min-height: 80px; position: relative; } .ud505fc7159f42079c114542bd089bdc2 , .ud505fc7159f42079c114542bd089bdc2:hover , .ud505fc7159f42079c114542bd089bdc2:visited , .ud505fc7159f42079c114542bd089bdc2:active { border:0!important; } .ud505fc7159f42079c114542bd089bdc2 .clearfix:after { content: ""; display: table; clear: both; } .ud505fc7159f42079c114542bd089bdc2 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud505fc7159f42079c114542bd089bdc2:active , .ud505fc7159f42079c114542bd089bdc2:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud505fc7159f42079c114542bd089bdc2 .centered-text-area { width: 100%; position: relative ; } .ud505fc7159f42079c114542bd089bdc2 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud505fc7159f42079c114542bd089bdc2 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud505fc7159f42079c114542bd089bdc2 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud505fc7159f42079c114542bd089bdc2:hover .ctaButton { background-color: #34495E!important; } .ud505fc7159f42079c114542bd089bdc2 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud505fc7159f42079c114542bd089bdc2 .ud505fc7159f42079c114542bd089bdc2-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud505fc7159f42079c114542bd089bdc2:after { content: ""; display: block; clear: both; } READ: That our intention judgeth our actions EssayTelevision has its positive and negative influences on childrens intellectual development and behaviour, but television as a medium does not have clear effects on patterns of cognition or achievement.

Matriarch by Veil of Maya free essay sample

Veil of Maya is a deathcore or djent band that have only released at least three albums so far. With 2012s Eclipse being one of the shortest full length albums I have ever heard of, and it isnt too bad either. Fast forward three years to Matriarch and now it seems they truly know what theyre doing and seem to show it as well. However, the full fledged review will be on in threetwoone. Matriarch is the bands third full length album album I believe and its one of those album that seems to go by really fast. I guess this is partially due to the incredibly short tracks and to the short length of the album its self. In fact the two shortest tracks are less than 2 minutes in length. Also, it seems as if they tried yo evolve into more of a Mathcore or metalcore based band because of the more frequent cleans on this album seeming reminiscent to bands like Protest the Hero, The Dillinger Escape Plan and As I Lay Dying. We will write a custom essay sample on Matriarch by Veil of Maya or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page However the classic VoM sound is still there nonetheless. A quick scan of the titles and you might notice that alot of them are references to geek culture, particularly anime. For example, Aeris is a reference to Final Fantasy, Lucy is a reference to Fairy Tail, and Mikasa is a reference to Attack On Titan and Im sure Ive missed a few. I guess this explains the album cover, it looks like something made in Japan for sure. The music takes on many different forms and likes to morph as well, so you are less likely to get bored of this album. If you do then this probably isnt for you then. The album as a whole isnt too bad but it doesnt have much of the chaos you find in say Eclipse. It is an evolutionary state yes, but I dont feel it as well here. Or maybe deathcore just isnt my thing, one of the too. I give this a 7.5/10. I can sense potential within it which, for the most part, they did succeed, however there were some moments that just felt off. I am the Grim Reaper, signing off.

Free Essays on English Bill Of RIghts

English Bill of Rights The English Bill of Rights set out strict limits on the Royal Family's legal privileges. It strictly prohibited the arbitrary suspension of Parliament's laws. More importantly, it limited the right to raise money through taxation to Parliament. The English elite had greatly offended the protestant Church of England when they began promoting the Roman Catholic religion, in spite of laws that Parliament had passed. Soon after William of Orange and his wife Mary were crowned King and Queen of England. (Mary was actually the daughter of the deposed King James II) in Westminster Abbey on April 11, 1689. As part of their oaths, the new King William III and Queen Mary were required to swear that they would obey the laws of Parliament. The Bill was completely passed through Parliament after the coronation ceremony for William and Mary. On December 16, 1689, the King and Queen gave it Royal Assent, which represented the end of the concept of divine right of kings. The Bill of Rights was designed to control the power of kings and queens. Another key factor was to make them subject to laws passed by Parliament. This has formally been called the "bloodless revolution" or the "glorious revolution." The Bill of Rights was one of three very important laws made at this time. The other two were the 1689 Toleration Act (which promoted religious toleration) and the 1694 Triennial Act, which prevented the King from dissolving Parliament at his will and held that general elections had to be held every three years...

Assignment 7 Essay Example | Topics and Well Written Essays - 1750 words

Assignment 7 - Essay Example There are three main components that every person as well as design should observe so that the feelings of the people involved are competently taken care of. The three aspects that need to be taken into account so that feelings of other people are taken seriously especially in design include appearance, behavior and their experiences or expressions. The three aspects need to be appreciated in the interaction with each individual so that they are able to connect with us. First, appearance or the visceral aspect as described by Norman (2004) describes the way we are able to appreciate how individuals react to the outward appearance of the product design. It is even imperative that we understand that appearance is even more important that functionality since most people are likely to perceive attractive things to be more user friendly than unattractive ones regardless of the real facts. The design should also take into account of the likely impact it may have on the pleasure or effectiv eness that will be attained by the potential users. In effect, to be able to seriously take into consideration the people’s feelings, we should be able to provide them with products that are likely to revitalize their fond memories. Lastly, it is important that the products reflect the individual’s rational and intellectual principles and that they are able to associate with it by even giving an explanation of how it functions. Norman (2004) has suggested that computers should therefore take the emotional component through well designed programs that are able to take into account the user’s feelings. It is quite strange but equally hilarious to think that computers can have emotions or at least, have an element of creating emotions. To some extent, I agree with the writer to the extent that computers and other digitech products should have basic elements of emotions so that they are able to be more users friendly. Whereas there is a big challenge of perfectly cr eating programs that will be faultlessly respond to different emotions and handle different personalities, it is important that computers are able to create some aesthetic value apart from the normal usability features. It is important that computers and other technological products are able to identify with historical and memorable events that people are able to connect them and not view them as insensitive tools. The writer is therefore right when he states that there should be a human part in the working of machines. He gives a good example of robots that he believes should do more than just assigned tasks so that they are viewed as more capable. However, in as much as the concerns of the writer may be genuine in addressing this great weakness of computer related design, it is still inconceivable to think that computers will perfectly fit to relay emotions and relate with different personalities. Like every being has different emotional frame and they may vary according to the en vironment or some historical happening among other things, computers may need to have complex systems that will integrate all these aspects in a single program that is likely to take immense efforts and massive resources to achieve. A2. The Philosopher’s Tool Kit Wittkower (2008) has raised an important component in product design by using the example of an iPod and the philosophy behind its much fanatical following.

Bone Marrow Transplant & Donation Essay Example | Topics and Well Written Essays - 1750 words

Bone Marrow Transplant & Donation - Essay Example ICU stay would usually be hectic with frequent monitoring, institution of mechanical ventilation, renal replacement therapy and continuous infusions. The conditions for doing bone marrow transplantations, selecting the donor if doing allogeneic transplants, the actual surgery, the prevention of immune suppression after the surgery and ensuring the survival of the patient have heightened the risk of the ominous event that is bone transplantation. This paper is exploring the biological features including the anatomy and physiology of bone transplantation investigated in the various researches. Initially the normal anatomy and physiology have been described so that the reader gets a better picture of what is intended by this research. Normal anatomy and physiology of bone marrow The soft tissue that lies in the spaces between the bone trabeculae of flat bones is bone marrow. Blood vessels, nervous tissue, phagocytes, stem cells and blood cells at different stages of maturation are found in the bone marrow (Elgazzar, 2004). The red marrow has hemopoietic cells which are active while the yellow marrow is mainly fat and hemopoietically inactive. The bone marrow is essential to the human life as it provides all the blood cells: red blood cells, white blood cells and the platelets. The manufacture of the blood cells depends on the needs of the body. Active bone marrow is found mostly in the flat bones of the vertebrae (28%), pelvis (34%), the cranium together with the mandible (13%), the ribs and the sternum, (10%) and the proximal ends of the femur and humerus (4%-8%) (Elgazzar, 2004). The manufacture of blood cells is termed hemopoiesis. It begins in the human body at the fourth month of the intra-uterine life of the fetus. Within two months it functions more than the liver in the hematopoietic action. By birth, the red bone marrow becomes fully responsible for the blood cell formation. The cartilaginous epiphyses which did not have the red bone marrow at birth soon had it in the first few months of life (Elgazzar, 2004). The adult bone has active red marrow in the various bones different proportions. The usual conversion of red marrow is to the yellow marrow. However in certain pathological conditions, the reverse process occurs. Alterations to the distribution of the red marrow could change in conditions which are traumatic to the human body like surgeries, trauma or infections or malignancy (Elgazzar, 2004). Immune response Lymphocytes were the natural killer (NK) cells which were significant role players in the immune responses, both innate and adaptive (Olson et al, 2009). Lymphocytes provided the response to virus attacks, microbes and some tumors. The NK cells were white blood cells produced in the bone marrow and then moved to the region of the spleen, liver, lung, blood and lymph nodes where they resided (Olson et al, 2009). The period of maturity from a bone cell precursor to maturity came to 28 days. When an attack from viruses or mi crobes or tumors occurred, signals reached the NK cells which then migrated to the sites of attack through the expression of inflammatory chemokine receptors by virtue of their homing behavior (Olson et al, 2009). At the key sites, the NK cells entered the lymphoid tissue in the lymph nodes and non-lymphoid tissue in
