Research Eosin Y with and without Phloxine B Reagents Paper

Eosin Y with and without Phloxine B Reagents - Research Paper Example The physical and chemical properties differ from one isomer to another. The highest melting point is 13.260C (55.870F) for p-xylene and the least is -47.870C (-54.170F) for m-xylene. All isomers have a boiling point around 1400C (2850F). In respect to density, all isomers have a density of around 0.87 g/ml that is less than dense water. In air, one can smell xylene at a concentration of 0.08 to 3.7 ppm while at water one can taste it at 0.53 to 1.8 ppm. In terms of appearance, xylene is a colourless and clear. The compounds related to xylene include benzene, ethylbenzene, mesitylene and toluene. Xylene is practically insoluble in water but soluble in non-polar solvents like the aromatic hydrocarbons (Pujado and Jones, 2006). According to Avery (2008) xylene, is commonly used in a histology lab for cleaning purposes. In the histology lab, technicians apply xylene for the purposes of tissue processing, deparaffinised and cover-slipping. It is termed as the best cleaning agent in a histology lab. It is applied before the infiltrating tissue in the cleaning process. To infiltrate a tissue peace with water, paraffin and alcohol must be removed. By removing, first, dehydration of tissues fixed with aqueous fixation is done by placing it through different alcohols starting from 50 % to 100 % through 70 %, 80 % and 95 %. After dehydrating the tissues, it must be cleaned using Histo-Grade Xylene form alcohol. After completion of this process, the infiltration of the tissue with paraffin can be done. Xylene can also be used in lab to prepare cover-slipping slides. The slides that are stained cannot be cover-slipped until the removal of water takes place. In order to dehydrate the water slide, the stained slide is placed into alcohol. After that the stained slide is placed into xylene in order to remove alcohol. After completion of this

Making a fair decision when bias is held on a subject Essay

Making a fair decision when bias is held on a subject - Essay Example Self-regulation, according to Gilovich, Griffin, & Kahneman (2002) refers to a sitaution where a person or organization adheres to issues as regarding legal, ethical or th standards of safety instead of having outside factors determining the decision making process. That is to say that an action odf decision must have a situational setting. The situational setting has basic rules and laws that determine the required end point in which case there is a strong positive out turn on the issue. As much as self-regulation has its level of conflict of interest, it is worth noting that there are no perfect decisions and each decision follows laid down rules (Starzak, 2012). Moreover, the aspect of self regulation considers wider perspectives from the individual to organizational level. However, there are also situation in which a group or individuals are thriving in unethical situations (Rezende, 2009). Consider the aspect of a bureacucratic society. If the society is asked to eliminate such, it may consider eliminating the respective unethical aspects witnessed as opposed to the ideal behaviour on the whole. That is a short run perspective (Starzak, 2012). Avoiding the issue of regulatory capture is an effective way of developing fair decision making (Rezende, 2009). The regulatory capture would consider that there are situations in which individuals with high stakes would want to advance their interests at the expense of the vast majority who have low stakes in the matter.
