Simple, reliable procedures for the assay of pepsin and rennin-like enzyme activities are described as a means of identifying gastric fluid-containing samples in forensic science laboratories. These samples are usually vomitus, or stomach contents originating from wounds that perforate the stomach. They may be encountered at scenes or on articles submitted for examination, in fresh form or as dried stains. The pepsin activity assay is based on proteolytic activity with bovine albumin as substrate and the rennin-like activity assay is based on the coagulation of milk protein. 相似文献

All published and unpublished population frequency data that could be located for U.S. populations are tabulated and presented for the blood group and secretor systems. Results obtained by combining data for comparable racial/ethnic groups are also presented. The results obtained with combined data may give better information on frequencies for the U.S. population at large than is obtainable from studies conducted in restricted geographic areas. 相似文献

This paper analyzes the welfare effects of term limits forstate legislators. Legislators tend to pursue their ownobjectives and deviate from the interests of voters as theystay longer in office. However, such long-term incumbentsbecome more productive in transferring wealth to theirconstituents due to seniority they gain, and voters re-electthe incumbent. Term limits reduce the maximum seniority of adistrict's legislator and of other districts' legislators aswell, affecting the relative seniority of the legislator.Thus, the legislator gains relative seniority sometimes andloses other times under term limits. As a consequence, votersof a district may or may not benefit from term limits. Thewelfare effects of term limits depend crucially on the shapeof the voters' utility function. 相似文献
