Background Interference of clinical laboratory assays by endogenous & exogenous substances in the blood is well known. To date, there are no clear guidelines on the testing of lipemic or bilirubinemic (icteric) plasma in clinical laboratories. A conservative approach of alerting the physician with re-sampling and/or processing with caution is advised. This study focuses on the effect of process...

Samuel Kotz University of Maryland Some heuristic tests for detection of existence of errors in inspection are proposed. Some of these tests are only effective if the sampling function ((sample size)/(lot size)) is rather large, and in all cases their application predicates special experiments to provide the requisite data. Feasibility of these experiments will vary according to specific circum...

Pressure tubes in CANDU reactor are the most important components that contain fuel. The operating experiences show leaks and burst in pressure tubes over the past two decades. The integrity of pressure tubes is, therefore, key concern in CANDU reactor. Once a CANDU reactor put into operation, their integrity could be checked by in-service-inspection. However, comparing to the total number of p...

Although progress has been made in regard to pathogen reduction technologies, the incidence and retardation of pathogens in the meat supply remains a high priority. As examples, on October 7, 2002, the Food Safety and Inspection Service (FSIS) issued a notice in the Federal Register mandating HACCP reassessments for E. coli O157:H7 and indicated that testing exemptions would furthermore be revo...

in this research, a new control policy for the acceptance sampling problem is introduced. decision is made based on the number of defectives items in an inspected batch. the objective of the model is to find a constant control level that minimizes the total costs, including the cost of rejecting the batch, the cost of inspection and the cost of defective items. the optimization is performed by ...
