Quadratic pieces of fleece measuring 16 mm2 were soaked with 10 different blood-samples in the dilution steps of 1:1, 1:10, 1:100, 1:1000, respectively, and were tested in blood group typing and identification tests of forensic serology. The above spezified dilutions correspond with 5 microliters, 0.5 microliter, 0.05 microliter and 0.005 microliter of blood, respectively. The detection limit of the microspectrometric test for blood was the dilution 1:10, of the porphyrine test a dilution above 1:100, whereas the preliminary test for blood (peroxidase) succeeded always up to a dilution of 1:1000 and the species determination by the radial immunodiffusion test in agar gels succeeded in most cases op to a dilution of 1:1000. The detection limit of the anti-human globulin inhibition test was between the dilution steps 1:10 and 1:100 when non-titrated and undiluted anti-human globulin serum was used. Gc- and ABO-grouping were possible up to a dilution of 1:100 and were thus the most sensitive grouping systems. Phenotyping of the enzyme-systems and the Gm/Km-system usually required stains with considerably higher blood concentrations i.e. stains of undiluted blood. 相似文献

In 1990, the state of California passed the pioneering mandate on zero emission vehicles (ZEV). This technology‐forcing regulation is aimed at improvement of air quality and protection of public health from the adverse effects of air pollutants from automobiles. Facing severe opposition from the auto industry, the mandate has been revised a number of times, most recently in 2003, whereby the requirement for ZEVs have been made to align with the pace of technology development. Review of strategies used in implementation of the mandate has revealed greater emphasis on the economic incentives for rather than on environmental merits of ZEVs. Using prospect theory as the framework for analysis, the reasons have been explored. The findings of the study help us to understand how decisions are made with respect with to deviations from a mental anchor point and through the process of evaluation of losses and gains. 相似文献

This study investigated the influence of an authority figure on eyewitness identification. Participants watched a staged crime
and then were administered a photo lineup by either an authority (policeman) or non-authority figure (civilian). Participants
in the authority condition were more likely to choose a lineup member than those in the non-authority condition. There was
no effect of authority, however, on the accuracy of the identification decisions. The lack of a deleterious effect suggests
that the presence of a police officer during identification procedures does not create an unduly suggestive situation or have
undesirable effects on eyewitness identification decisions. Although witnesses' choosing behaviors did not increase the rate
of identification errors, the effect of the administrator's authority on choosing was reduced when unbiased instructions (vs.
biased instructions) were presented to the witnesses. Thus, support was found for the use of neutral instructions during eyewitness
identification procedures. 相似文献
