Title Biochemical Analysis of Blood Abstract Introduction After blood is collected from a patient it is analysed to check the fragments present and the fluid which will either be plasma or serum. After plasma is separated from blood it recollects the fibrinogen which in turn helps in clotting however serum is the portion of blood which remains after the fibrinogen is removed. Serum contains approximately 6-8% of the proteins which make up blood however plasma creates up to 55% of blood

Introduction: Glucose is one of the few chemical constituents of the blood that can change noticeably in its concentration. Many diseases cause a change in glucose metabolism but the most frequent cause of an increase in blood glucose is diabetes mellitus. The early detection of diabetes is important to avoid the many complications of the disease. The glucose tolerance test commonly done by recommended level for adults of a 75 g glucose drink to be consumed within a 5 min time period. The timing

Process control at Polaroid Basing your analysis on both quantitative and qualitative tools‚ what evidence is there that quality is getting better? Pod Weight control According to Pod Weight control chart in Appendix‚ the pod weight performance variability is within the control limit (between 2.774 - 2.835)‚ which means the process is in control. This indicates the quality is getting better since the Pod Weight defect rate is normal (Pod Weight measurement is a part of defect report issued

Experiment #9 – Identification of Aldehydes and Ketones Introduction Aldehydes and ketones share the carbonyl functional group which features carbon doubly bonded to oxygen. In the case of ketones there are two carbon atoms bonded to the carbonyl carbon and no hydrogens. In the case of aldehydes there is at least one hydrogen bonded to the carbonyl carbon; the other attachment may be to a carbon or a hydrogen. In all cases the carbon(s) that are attached to the carbonyl group may be aliphatic (not
