Biology: Separation of Proteins

1150 words - 5 pages a basis from which a detailed study of proteins is possible. Following our procedure we were successfully able to set up a quantifying assay to determine the amount of protein within a milk sample, although our yield percentage was rather low. However, errors in this lab (in the form of a low yield percentage) may have an origin from our last lab. In the process of extracting proteins from the milk sample, we may have inadvertently lost some of the protein through erroneous measurements, or perhaps through poor handling of either ammonium sulfate or the dialysis tubing. While not sufficient enough (at this point) to invalidate our results, they do explain the major difference between the expected and the actual amount of protein extracted.

Also, in conventional Raman spectroscopy a dispersive grating is used to analyze scattered light. In FT-Raman, the advance alternative to this dispersive grating incorporates the use of a Michelson interferometer for analyzing scattered light.

The Function of Pharmacokinetics

1057 words - 4 pages different parts of an organism that have been isolated or grown in the laboratory settings. This method of study will help us to find the specific analysis than can be done with whole organisms The question that rises in this essay is how we describe a new approach to enumerate in vivo activities by simulating pharmacokinetic factors in vitro. The general approach to this question has to cover three specific areas. The areas are in vivo measurement of the drug therapeutic and toxic effects. Then we need to measure those effects by using pharmacokinetics measurements at the specific site of the body. At the end we need to use pharmacokinetic simulation of the time versus drug concentration VIEW DOCUMENT

localization

1551 words - 6 pages statistically robust or difficult exercise, a good description of the variables helps the researcher evaluate the statistical output in the proper context.Some researchers think that quantitative research is better than qualitative research at establishing causality because of the precise measurements and controlled environment of experiments; however qualitative studies can also be used to establish causality but with less external validity. Laboratory experiments are used when all extraneous variables need to be controlled so that the specific action and effect of the independent variable can be controlled. In addition, it may be important to be able to replicate the study and a laboratory VIEW DOCUMENT

web-based simulation in nursing

1706 words - 7 pages simulation has used digitally developed robotic human figures; in one study the characters were pictured in storylines experiencing a variety of disorders that required assessment and nursing interventions (Holland et al., 2013). Overall, technology-assisted training for health professionals (that encompasses any of the full range of simulation techniques) was shown to have a large effect on knowledge, skills and behaviours compared to no education (Cook et al., 2011). Which technique is best? Positive impacts of laboratory-based simulation on clinical performance are well recognized (Agency for Healthcare Research and Quality, 2009; Cant & Cooper, 2009; Lasater, 2007; Lewis et al., 2012 VIEW DOCUMENT
