ISOLATION AND CHARACTERISATION OF LYMPHOCYTES Lab Report

ISOLATION AND CHARACTERISATION OF LYMPHOCYTES - Lab Report Example This is because this results in an inaccurate count. The same is true if the cover slip is moved after the sample is loaded. To make randomized counting only the 4 squares at each end were picked and then the 16 small squares within each large square, that is, in an organized zigzag along the rows. To make the counting standardized only cells lying on the bottom and right hand boundary were counted in and a cell lying on the top or left hand boundary were not counted in. This was in order to avoid counting cells twice. Normally, at least two squares should be counted, comprising more than 100 cells within each central counting area of every square. For higher accuracy, additional cells can be counted and the mean used to compute cell concentration. The result of cells counts were in the table 1 below. The other cells in the splenocyte preparation are red cells 3.82%, Granulocytes 6.1% as shown in the table 4 above. The abundance of small lymphocytes shows that the cell suspension has more immature cells which are maturing in the spleen to become large lymphocytes and T-lymphocytes. With time the population of small lymphocytes decreases as they develop to large lymphocytes, medium lymphocytes and T-lymphocytes. The spleen is made up of immune lymphocytes and that why in this experiment there were low number of other types of cells. Time was very important in this lab because long exposure could lead to lack of the reliability. This is because the population of splenocytes keep on changing since some cell has not matured fully and other are multiplying. For this lab the time limit was hour since In this lab exercise, Nigrosin was used to stain any dead cells. Nigrosin is an acidic stain. This means the stain readily gives up a hydrogen ion and becomes negatively charged. Since the surface of dead cells is negatively charged, the cell surface repels the stain. Thus slide glass will stain, but the dead cell will not. The dead

Maternal mortality Essay Example | Topics and Well Written Essays - 1750 words

Maternal mortality - Essay Example The excessive loss of blood causes the deficiency of both oxygen and nutrients to such vital organs of the body as the brain thus causing instantaneous deaths. Causes of the excessive bleeding include tearing of the uterus walls, poor contraction of the uterus and poor blood clotting. Postpartum infections on the other cause more than 10% of the reported maternal mortalities. Postpartum infections refer to any bacterial infections of the female reproductive tract after childbirth. Among the notorious risk factors of the infections are the cesarean section, prolonged labor, the presence of such bacteria as group B streptococcus in the reproductive organ and premature rupture of the membranes of the uterus among others. Complications arising from unsafe abortions cause more than 15% of the reported cases of maternal mortality. The complications are always as diverse as the techniques that people use to procure abortions. In most countries, abortion is an illegal practice a feature that compels pregnant women to seek the services of quacks especially in such developing countries as India. Most women die from excessive bleeding and infections among other complications arising from unsafe nature of the procedures. The prevalence of maternal mortalities in India represents the gap between the rich and the poor since most of the reported cases occur in the impoverished neighborhoods and are minimal among the rich. Furthermore, they portray the inequalities that exist in accessing high-quality health care services.

Six Essential Elements of Geography - Essay Example Physical systems – this element of geography seeks to study physical processes such as volcanoes, glaciers, climate, and how they shape the earth. In addition, it seeks to study the interrelationships among plant and animal life and their natural environment that sustain life. Environment and the society – this element studies the impacts of human activities on the environment. In addition, geographers are also interested in knowing how humans use the environment and how the environment influences people’s lives. The uses of geography – this element show the importance of acquiring knowledge on geography. Geography is essential to humans in that it helps them understand the future as well as the past. This knowledge enables geographers to understand better the relationships between the environment, people and places (Swamson 56). The teacher can apply the first essential element of geography in describing the absolute or relative location of a particular object. For example, the teacher can inform the students that the Geographic information centre is located at 805 Sherbrooke Street West (absolute location) or Sherbrook Street West near the Catholic Church (relative location). The second element (places and regions) is applicable in distinguishing various parts of the world. For example, the teacher can use this element to explain the difference between the tropical regions and temperate zones. The teacher can apply the unique element of physical system by explaining to students the role played by natural phenomenon such as volcanoes, movement of glaciers and hurricanes. For example, volcanoes can produce rich soils that can support farming. On the flip side, volcanoes can cause destruction of natural vegetation and displace people. The teacher can apply human systems in explaining human settlements. For example, the teacher can be able to explain why there are so many

Academic Misconduct - Research Paper Example Through such a level of discussion and analysis, it is the hope of this author that the reader will gain a more informed and rational understanding with respect to societal norms, the means through which individuals seek to engage with cheating as a means of benefiting themselves The innate and tacit drive for cheating (as well as what causes it), the benefits as compared to the risks, and the types and variety of cheating that is represented throughout scholastics within the current era. Further, a cursory analysis with regards to the scope and impacts of unlimited cheating will be discussed. Firstly, it must be understood cheating is something of a social phenomena within the world. Although the impacts of cheating within scholastics have only recently come to a broad level of understanding, the fact of the matter is that cheating is a type of social problem that traces its origins back to the innate desire for an individual to gain a competitive advantage over his/her peers with the least amount of effort. Ultimately, the human spirit is one that continually seeks for self betterment and a level of advantage over their fellow students (Bing et al. 29). Oftentimes, this desire to be better engages the individual to try harder and exert their selves more fully. However, oftentimes, the case is that the individual seeks a shortcut with regards to maintaining an advantage and reaching a desired goal. This shortcut can either be the reduction in the overall quality of the work that they represent or it can be referenced with regards to the fact that the seek to cheat in one form or the other as a means of providing themselves the benefits that had previously been mentioned. Regardless of the way in which cheating is defined, it must be understood cheating is not localized to the University or secondary education systems. Rather, from an early age, children are made aware

What are the effects of temperature on electricity demand in Essay

What are the effects of temperature on electricity demand in Sacramento, California in July and August 2008 in the daytime - Essay Example Moreover, positive linear relationships have appeared between the electric consumption and the selected variables of weather conditions. For proper planning of future investments in energy generation sector, policy makers require forecasts of electricity demand. The demand of electricity consumption in California has more than quadrupled since 1960. There are various factors, which are contributing to the increased energy consumption in California such as uncertain regulatory environment, swift population growth and economic growth.
