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

We discuss Professor Jeffrey Church's report to the EuropeanCommission in 2004 on the effects of vertical restraints andmergers. Although thorough and accurate, the report could bemisinterpreted by practitioners, as it does not emphasize thatmarket power is only a necessary condition for harm to competition,and that most vertical mergers that present the possibilityof competitive harm also present economic efficiencies thatare intrinsic to the integration. 相似文献

Regime transformation from below: Decentralization,local governance,and democratic reform in Nigeria
James S. Wunsch Dele Olowu 《Studies in Comparative International Development (SCID)》1996,31(4):66-82
How realistic are democratic-governance strategies that emphasize local governance as a key component? Using Nigeria’s experience in local government and primary health care in the 1980s and 1990s as a case example, the article finds there were substantial shortfalls in local participation and program performance. These were caused by problems in the local political environment and local institutional design, in the national policy environment (particularly in the funding system), and by the stresses of structural adjustment, resource shortfalls, the natural physical environment, and weak leadership. These combined to create poor and inappropriate reward structures and lack of accountability. However, even though the Nigerian case was not successful, most of the specific problems that hurt it are remediable through policy changes at the national level. Several of these were under consideration at the time of the coups of 1992 and 1993. 相似文献
