Abstract

Introduction
Assissted reproduction technology (ART) can be defined as a technique that bypasses intercourse in order to follow biological pathways and manipulation of such pathways leading to pregnancy and the birth of healthy offspring(Velazquez, 2008). ART in humans has been used most effectively since the 1980’s fist concentrating on male human semen and understanding the estrous cycle of females of the same species, before long farm animal stocks were looked at. The ability to manipulate the breeding of certain genetic traits was seen as industrious, making pigs bigger, cows that produce more milk, chickens that laid more eggs and so forth.(Foote, 2002)
Antonie van Leeuwenhoek and his assistant Hann were the first to discover sperm in 1678, they named them animalcules due to the sperms animated appearance and small size. Little was it known then the research and industrial and natural impact this discovery would have (REF).
The first recorded western insemination was recorded in 1784 by a priest named Spallanzani who whelped 3 puppies from a dog. Much work was being done across Asia but due to lack of linguistic knowledge much of this work was unknown until a translation and review was made in 1958. By this time ART was a rapidly growing technique in the subject of this report dairy cattle(Foote, 2002).

Techniques
The first step is collection of semen from the male bulls. Semen is collected at a temperature between 42-45c and maintained in a water bath at 30c. As many as 5 ejaculates can be collected per day during certain seasons if collected using an artificial vagina. When using anal electrode treatment not as many collections can be made due to distress on the animal.
Sperm must then be analyzed for it virility. By looking for discoloration a decision can be made if the sample is contaminated by blood or urine. It is imperative that all…...

...Abstract Conductive polymers or, intrinsically conducting polymers (ICPs) are organic polymers that can have metallic conductivity or semiconductivity via conjugation and co-doping. Polypyrrole (PPy) as a kind of heterocyclic conjugated conductive polymers is considered to be the most prospective electric conductive polymer due to its relatively high conductivity, stability, and other characteristics. Recently, PPy /magnetic nanoparticles composite materials have become a research hotspot, for its potential application in electromagnetic shielding, molecular electronics, nonlinear optics, absorbing materials, etc. The preparation of this material is mainly through in-situ polymerization. The polymer wrapped around nanoscale magnetic particle via particle-substrate interaction to form a core-shell structure of polymer /magnetic nanoparticles composite materials. But study also shows that this kind of polymer coat may reduce the saturation magnetization of the magnetic nanoparticles. Three methods—chemical method, electrochemical and O/W microemulsion synthesis method were used to synthesize different structural types of PPy. The Four probe method shows that it has good conductivity (793.7 S.m-1).The TEM indicates that the PPy synthesized through O/W microemulsion has better controlled nano size and thus we chose the PPy synthesized by O/W microemulsion to interact with magnetic Co nanoparticles via ligand substitution reaction. The PPy/ magnetic nanoparticles composite......

...Abstract Asia-Pacific countries have experienced a rapid rise in Internet usage in recent history. China, in particular, has seen 40% of its population (or 500M people) connect to the Internet in the past 10 years, and continues to experience an increase in its user base. This large user base, coupled with a rise in wealthy households and per capita spending, is driving a dramatic increase in e-Commerce retail, specifically in the luxury goods space. Consumption of luxury goods in China has reached $9.4B in 2010, second only to Japan in the world. As luxury purchase rates continue to increase in China, luxury fashion brands are investing many resources to understand the customer, develop the market, establish the supply chain, and deliver the products. Polo Ralph Lauren (PRL), in order to continue its growth in China, is expanding aggressively through license reacquisitions and retail store developments. Furthermore, to provide its existing customers with additional products and enhanced services, and to capture consumers who live in cities without access to PRL's brick and mortar stores, PRL has set its vision to develop an e- Commerce business in China. This thesis provides a fundamental understanding of PRL's current business operations and of current e-Commerce fulfillment models for luxury apparel brands in China. An assessment of gaps was also conducted between current fulfillment operations of PRL and those of other luxury brands and 3PLs operating in China,......

...Abstract: | Knowledge management is identified as a key success factor in most industries today. While data or information can be stored independently from people, knowledge is bound to people who use it for their interactions. The main goal of knowledge management is to improve the usage of knowledge in the enterprise. Knowledge management systems are not only organizational memory information systems. They also contain organizational standard procedures and a certain cultural attitude. A reference framework gives implementation hints mainly influenced by technical possibilities. The knowledge management system reference architecture contains layers of sources, repositories, taxonomy, services, applications and user interfaces. A software tool that largely corresponds to this reference framework is the Knowledge Café. Possible applications of this tool to the area of hospitality and tourism are described in this paper. | Information technology has changed how businesses operate and succeed in today’s global economy. Organizations can now use IT to transform themselves and achieve a tremendous competitive advantage. Information Technology for Management: Transforming Organizations in the Digital Economy, Seventh Edition highlights how this new technology is changing the current business environment and what effect it has on today’s students.  The text addresses the major principles of MIS in order to prepare managers to understand the role of information technology in......

Technology Solution Abstract

...Data management in the lab is a mixture of various independent, nonintegrated data-processing systems on paper and in electronic form. Paper is the preferred documentation medium when you have a mix of countless computerized systems such as analyzers, office applications and upper-level systems, for example, laboratory-information management or enterprise-resource planning (ERP) systems. Such a scenario results in producing a hybrid system with numerous media gaps this is the real root of all evil, leading to ine The high level of quality risk (due to the high number of manual data transcription steps) is countered with extensive control steps – but that results in less efficiency and longer throughput times. The use of isolated systems prevents the timely transfer of information, which leads to further delays and additional costs. And last, but not least, it can result in a considerable amount of the enterprise’s intellectual capital being wasted. The cost of using various isolated systems to collect data for modern knowledge-management systems (statistics, data mining, reporting, exception handling, etc) is simply too high. So much knowledge that could be extracted from the data collected remains untapped. In the industry, there are three different approaches to addressing this root problem. • The first – is the optimization of the existing hybrid system by adapting the existing processes and systems. It goes without saying that such an approach only brings selective and...

...ABSTRACT This literature review will discuss the impact facebook has on productivity levels within an organisation. The initial facebook users were comprised of college students that could meet at a place online and socialise as well as being able to share pictures with each other. However, in recent times, facebook can now be accessed by anyone around the world ' with almost 100,000 people joining up every day. Due to the hype of this new socialising phenomenon, organisations are beginning to fear that accessing sites such as facebook during working hours will have a negative impact on productivity levels ' which is the bases as to why this literature review is being conducted. The gap that this literature review will attempt to fill is to clarify that facebook could prove to be beneficial tool for a company as it will be a method of not only reducing employee stress but it is also a way of keeping in touch with everyone ' including clients as well as potential clients.

...Management Theory & Practice Tara Neitzel MGT/230 13 January 2014 Hilary Johnson- Lutz Abstract There are many times in my life that I have had to make executive decisions to make certain changes in my life. One change in particular that I have had to embrace recently is changing my job. There were many decisions made in this big change, it took a lot of thought, planning, and the weighing of pros and cons. In this paper I have decided to go into depth about this change, which led to many differences in my everyday life. Management Theory & Practice Recently I had to make some big decisions about changing my job from one career to another, from one city to another. I had to make the decision based on many factors. First I began looking for another job, I was trying to decide how far away from home to search, what field I want to work in, what salary I was willing to take, really, what will make me happy in all aspects. First, I had to decide how far I was willing to commute. Time is huge for me, and I wanted to make sure it made sense, as I was working 5 minutes from home with my job at the time. But I just wasn’t happy. So I set out to find a job within a reasonable distance from my house. I started looking into staffing agencies, and doing my own search for a job. I came along an interesting job, something I thought I might enjoy, and the salary was about right for me, the only problem was that I could not get over that my commute to......

...Abstract As year pass by technology continues to evolve and grow and businesses started shifting from using the manual systems to computer-based systems. These systems make it more efficient for the business to make the transaction can be further improved. Swain states that pawn shop is an easy way to get a cash loan quickly. Pawn shops either directly purchase or make loans on valuables, using them as collateral for a short term loan, generally with a repayment period of thirty days. If the loan is not repaid within the time frame outlined in the loan agreement, the pawn shop then owns the item released to their custody as collateral. (Swain, K. 2010) According to Coleman If you have received a loan from a pawnshop, be sure that you pay it on time. If you do not, there are extra interest rates that are associated with paying it later. Usually you may have 90 days to repay your loan. If you do not repay the loan, the pawnshops will keep your item and sell it. (Coleman, N. 2012) The researcher noticed that the customer of the Pawnshop’s is not always updated about their pawned item. With Pawnshop Customer SMS Notifier is a system that will improve the Pawnshop’s task in accommodating their customer. This system can give update to all customer of the pawnshop about the status of the item that they pawned through SMS and email. It can also notify the customer about the Pawnshop’s auctioned items....

...Abstract Understanding evolution helps us solve biological problems that impact our lives. There are excellent examples of this in the field of medicine. To stay one step ahead of pathogenic diseases, researchers must understand the evolutionary patterns of disease-causing organisms. To control hereditary diseases in people, researchers study the evolutionary histories of the disease-causing genes. In these ways, knowledge of evolution can improve the quality of human life. Evolution played an important role not only for the present day humans but all living things today. As you all know, we didn’t just evolve out of nothing, we all have an ancestor whose ancestor’s ancestor is our ancestor and so on. When we can’t go back any further because of the given facts, we know that was every organism’s common ancestor. To understand the importance of evolution, we must gather some understanding of the meaning of evolution. Here is biological evolution defined by one of the most respected evolutionary biologists, Douglas Futuyma. "In the broadest sense, evolution is merely change, and so is all-pervasive; galaxies, languages, and political systems all evolve. Biological evolution ... is change in the properties of populations of organisms that transcend the lifetime of a single individual. The ontogeny of an individual is not considered evolution; individual organisms do not evolve. The changes in populations that are considered evolutionary are those that are inheritable via......

...Abstract: baumbusch j., dahlke s. & phinney a. (2012) Nursing students' knowledge and beliefs about care of older adults in a shifting context of nursing education. Journal of Advanced Nursing 68(11), 2550-2558. Abstract Aim. To a report a study of improvements in students' knowledge and beliefs about nursing care of older adults following completion of an introductory course with integrated adult/older adult content. Background. Nursing schools are under pressure to provide accelerated programmes to meet growing workforce demands and provide students with the knowledge they require to care for an ageing population. Thus, stand-alone courses in gerontological nursing are being eliminated and integrated with general adult content. The effect of this approach remains poorly understood. Design. A one-group pretest-post-test design was used. Methods. Data were collected between September-December 2010. Students completed the Palmore Facts on Aging Quiz, the Perceptions of Caring for Older People Scale, and open-ended questions about their experiences before and after completing a course with integrated adult/older content. Results. Students' knowledge and beliefs about nursing care of older adults demonstrated an important improvement following completion of the course. Qualitative findings reflected three themes: relating to older people; neglect by the system; having time to learn. Conclusions. Findings from this study suggest that even when integrated with general adult......

Impact of Technology from the Internet on Creation, Reproduction and Circulation

...COM 339 Professor Neff Lesson 10 Synthesis Paper You use the internet to do just about everything now a days, buy, sell, trade, read, etc. this just shows how the internet is definitely changing cultural production. New media enables new cultures to transform societies. The internet is a key tool for businesses these days. The impact of technology from the internet has changed the creation, reproduction and circulation of cultural products now. Since the internet is so popular, cultural producers are able to see what is “in style” or “hip” at the moment so they can make creations of a new product based on what is cool at the time or what they think will be in the future. This is how executives and producers see if something will be a hit, like William Goldman says in “Is Justin Timberlake a Product of Cumulative Advantage?” They can also use the internet for reproduction purposes by seeing how popular the item is online, or from orders from people from the internet. Then they post all about how neat their new product is by “hash tagging” or having people talk about it on social media so the product circulates and becomes popular. Cultural producers want their items to be shared on the internet so that it becomes the new trend to have; something the alpha customer will want. For example, let’s use a new CD album from a band. The band can create their album and put it online so it streams for consumers to buy. They will reproduce more and more copies to put up......

...Abstract Entrepreneurial Leadership has different definitions as well as different philosophies behind them. Successful leaders such as Steve Case, Peter Drucker and James Kouzes have all developed philosophies, associated attributes and best leadership practices to be successful in today’s fluid marketplace. There are commonalities and a leader can pick portions of different practices or beliefs to form a hybrid philosophy for leading change within their organizations while following Tarabishy’s (n.d.) recommendations for entrepreneurial leadership in today’s dynamic markets. Leadership is comprised of different styles. Organizations are different and so are the traits and styles of its leadership. While leaders want to accomplish the same thing, a successful organization, the methods of authentic, transformational and transactional leaders are different. As organizations and the associated leaderships differ, there are tools and resources that can help leaders in achieving its organizational goals. The Small Business Administration and Counselors to America's Small Business (SCORE) are two organizations that provide resources to assist leaders such as mentoring, starting a business, loans and training. Once leadership styles are understood and a philosophy is created, a leader can then develop a list of best leadership practices that best suits the leader and guides the organization to meeting its vision and goals to achieve competitive advantages and......

...Abstract Diabetes mellitus is the most common form of diabetes, influenced by the pancreatic hormone insulin deficiency, this, in turn, leads to failure in starch and sugar metabolism. As a result, the accumulated sugar floods the blood and urine causing the imbalance of acid base in the blood causing risk of coma and convulsion. Diabetes mellitus is typically common almost in every generation. The prevalence among children, youths, and adults has raised an eyebrow. People's response towards diabetes mellitus has built a good number of concern in us and perhaps worldwide, owing to the fact that some of the diabetes mellitus patients lack access to proper medication. Also according to Bogner et al. (2012), depression is usually common in diabetes which has negatively affected the provision of medication raising morbidity and mortality rate. Furthermore, as per Vietri et al. (2016), strict adherence to antihyperglycemic is thought to be sub-optimal, he added that drug abuse where some of the patients miss drugs are on the rise. Financial problems, lack of awareness and age which tend to deter mobility were an issue. The suggested some of the intervention mechanism that should be considered by both the individual and the government. For example under the individual take, they should avoid some of the pre-exposing factors such a lot of sugar intake and adhere to the prescription given by the physician. The government should as well come up with proper public sensitization......

...roaming far and wide until a late hour, seeking, amid the wild lights and shadows of the populous city, that infinity of mental excitement which quiet observation can afford. At such times I could not help remarking and admiring (although from his rich ideality I had been prepared to expect it) a peculiar analytic ability in Dupin. He seemed, too, to take an eager delight in its exercise—if not exactly in its display—and did not hesitate to confess the pleasure thus derived. He boasted to me, with a low chuckling laugh, that most men, in respect to himself, wore windows in their bosoms, and was wont to follow up such assertions by direct and very startling proofs of his intimate knowledge of my own. His manner at these moments was frigid and abstract; his eyes were vacant in expression; while his voice, usually a rich tenor, rose into a treble which would have sounded petulantly but for the deliberateness and entire distinctness of the enunciation. Observing him in these moods, I often dwelt meditatively upon the old philosophy of the Bi-Part Soul, and amused myself with the fancy of a double Dupin—the creative and the resolvent. Let it not be supposed, from what I have just said, that I am detailing any mystery, or penning any romance. What I have described in the Frenchman, was merely the result of an excited, or perhaps of a diseased intelligence. (…) We were strolling one night down a long dirty street, in the vicinity of the Palais Royal. Being both, apparently,......

...The Power of the Branding Abstract A brand is the visual, emotional, rational, and cultural image that one can associate with a company product goods and/or services. A brand is a strategic element of a company’s overall marketing organization as it provides a structure to influence strong brands into other markets, integrate newer brands, and rationalize the company’s value based on the product and/or service the business offers. Introduction Living in a modernized era, with accelerating numbers of businesses built to satisfy consumer needs and wants, branding has become more of an important value in building a company’s image for its products or service. In conjunction with the company’s goals, employees, vendors, reporters, communities, target customers and consumer mix, which all are contributing factors in making the proper representation of what the business would like for people to see them as; furthermore the company’s branding will ultimately represent the understanding of the needs and wants of the customers and prospects the company seeks to target by incorporating the company’s brand at every point of public contact and with every marketing opportunity. Therefore, branding helps to......
