Hi, need to submit a 500 words essay on the topic Principle cells of the immune system.

Three of such principal cells of the immune system are lymphocytes, antigens, and effector cells. Below, brief descriptions of the roles of these three cells in immune response are discussed.

Lymphocytes have been noted to be cells that emanate from stem cells within the larger immune system. As far as immune response is concerned, the lymphocytes take charge of the adaptive response (Guermonprez et al., 2012). For this to happen, there are a series of functional activities that come together. Working together with specific receptors, the lymphocytes function towards the recognition of specific antigens that enter the body. Consequently, the effect of antigens in the body would be hampered if the lymphocytes are not functioning properly. Bryant, Trinder and Curtis (2004) also noted that one the lymphocytes emanate from the stem cells, they go on to form three different populations of cells which are B cells, T cells and natural killer (NK). Of the three however, it is the B and T cells that take part in the adaptive immunity as NK cells function as innate immunity. The B cells for example produce antibodies, whiles the T cells engage in cell-mediated immunity (Guermonprez et al., 2012).

The second principal cells are the antigen presenting cells, which have the core role of aiding the lymphocytes to undertake the adaptive response. In some cases therefore, the antigen presenting cells are considered to be also responsible for adaptive response. The antigen presenting cells function by bringing antigens to the lymphocytes. Writing on the anatomy of the immune system, Zen and Parkos (2003) indicated that the location of the antigen presenting cells (APC) makes it very convenient for it to play its role. This is because these APCs are found in the periphery. From this location, they are able to examine the tissues to identify antigens. One major difference between the function of the lymphocytes and APCs is

Hi, need to submit a 500 words essay on the topic Progress Report for PDR.

The project team especially the team responsible for engaging interviews with the stakeholders especially the secretaries and assistants in the faculties do not corporate. This has resulted into getting inaccurate information that is supposed to aid in system development.

During our progress we found out from external sources that have successfully carried out the same implementation that the best method of developing a system that will meet the user requirement is by engaging the users from the initial phases of the system development. This will enable the development team to refine the system requirement from the early stages such that the time spend during testing will be reduced. Information about this output can be downloaded from www.suceesssystempro.net. This gives the detailed report on the above methodology and also provide case example that are real.

After integrating the new method of user involvement, we realize that there are a lot of disparities in terms of functional and non functional requirement. This is as a result of disparities in the users needs especially the students. We found out that some students and a few staff do not have internet knowledge and therefore the system interface should be made in a way that will not frustrate them (Wiegers 426)

The programming team are doing very well so far in coming up with prototypes that are subjected to test by exposing it to students and staff for use. The other sections are progressing well except that more resources need to be pumped into data entry team because we realized that the database that was used previously had a lot of vulnerabilities in terms of data security. As such we had to come up with a new database using mySQL (Bolles, 125)

During the past one week we had to make a formal communication to different faculties to corporate with the data collection team that goes round collecting

Project Module 2: INSIGHTS GROUP

The permanency nature of adhesives tends to make repair and adjustments in vehicles very difficult as they are strong and difficult to undo. (5) Its use lacks the required skills and expertise since most engineers are not trained to use adhesives hence they prefer bolts to adhesives. And (6) difficulties in measuring the tightness and firmness of the use of adhesives in binding materials unlike in the use of bolts and nuts (Hagerty & Ramsey 3). Nevertheless, automakers are looking for ways to overcome the above challenges by training engineer with special specialties on using adhesives and deriving ways to improve the ability of adhesives to withstand high pressures of more than 6500 pounds of force per square inch and endure high temperatures.

Ford influenced the sharing of technology with suppliers by prompting Alcoa Inc. to share its pretreatment technology in exchange for loyalties. As a result, this made aluminum more compatible with adhesives thereby increasing on its use in terms of quantity and improvement in performance. Additionally, this fostered the aluminum market by increasing its shares since aluminum does not easily weld to steal but can be easily glued to it. For this reason and in accordance with John Hill who is a Ford researcher for adhesives, the use of adhesives in the automotive industry increased significantly whereby structural adhesives global market will increase from $1.5 billion to $2 billion.

Hi, need to submit a 500 words essay on the topic Reaction Paper to Deaf Culture and/or Issues.

The protests, aided by handheld mobile communications devices, were successful in their goal of eliminating Fernandes as President. A few years ago this would not have been possible. The technology that aided the students was able to catapult the need to organize into a highly efficient system of cooperation.

The devices, mostly Blackberries and Sidekicks, provided the deaf students with the instantaneous reaction and response that was necessary to carry out the movement. With this resource the students were very adept at relaying messages and focusing their efforts. T-Mobile has realized the value of these devices to the deaf as they have offered a data only subscription to their existing cellular network. Beyond the obvious use of technology to solve a problem, it also highlighted the phenomena of necessity creating excellence. Hearing students have the same technology available, but would not have reached the organizational extent that the deaf students did. This must have come as some surprise to the administration and university officials.

It would be easy to assume that the deaf students would act with a certain degree of timidity. In the past, deaf students were faced with the obstacle of uniting with the difficulty of the speed of traditional communications. As Christopher Corrigan, a 20-year-old junior, says, “Without the pagers we would have to have people running to the dorms to get people”. Yet when technology availed itself, the deaf community was able to put it to work and gain its maximum value. Hearing students would probably not have been able to focus their efforts any more precisely than the deaf students did. Technology that is taken for granted often ends up misused or neglected. In the case of the deaf students, their challenge necessitated that they appreciate and use the technology to its fullest extent.

What other technologies are lying dormant and neglected out of complacency?

Hi, need to submit a 500 words essay on the topic Reading Report.

Donovan was not expected to be omitted due to his being a three- time veteran of world cup and the best known American player. Dempsey was however picked due to his absolute advantage over his other fellow players including Donovan. In economics, absolute advantage therefore occurs when an individual, a group or company or a country is more efficient and effective in producing the same good or service than any other individual, company or country.

In this case therefore, Clint Dempsey has an absolute advantage over his other players. For instance, he has managed to score eight goals in nine games meaning he scored almost in every game. This is a trait that only a few would achieve. He also has that innate ability of finding a goal in every game he is involved in. The coach of Los Angeles Galaxy Bruce Arena says that he has that driving force with which he does things for himself you can’t keep on telling him during the entire game. He is also very well motivated and uses that as his secret to play well.

Another concept in economics is the opportunity cost. This refers to the value of the best forgone alternative. In this case both Dempsey and Donovan are alternatives but the coach has decided to prefer Donovan to Dempsey, thus risking a certain value. The coach has given up the chance to use Donovan and sacrificed the wins they would have had. It meant that Donovan and the value of Donovan was forgone, therefore being the opportunity cost. Opportunity cost is therefore a scenario experienced by most of us in our daily lives (online.wsj.com).

Comparative advantage is the ability of an individual or country to produce services or goods at a lower opportunity cost than any other individual or country. Dempsey and Donovan can both play well though Dempsey seems to have an absolute advantage over Donovan. In this case, we don’t look at the absolute advantages but the opportunity costs. The Dempsey can play a
