Operations Performance Analysis

1694 words - 7 pages rate.ConclusionAs seen by the two simulations, systems' thinking is critical to identifying performance measurements and implementing metrics. UoS had to use published industry information to help them identify areas of improvement for them to meet the mission and goals of the university. Likewise, Thistle Woods looked at internal metrics and benchmarking to identifying the area that was having the greatest negative impact on the overall performance of the system. While the ER was experiencing the end results of not having enough beds, it cause was identified to be outside of the ER specific system, namely in the laboratory."Applying systemic concept such as interdependencies, feedback, and boundaries has VIEW DOCUMENT

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.
