A complex investigation of catalase activity in erythrocytes was conducted basing on the results of computer quantitative morphometry of histochemical examination of blood samples from persons with mild craniocerebral trauma. It was found that erythrocytic catalase activity correlates with severity of brain trauma. A novel technique of objective histochemical diagnosis of trauma is described. It provides objective grounds for expert conclusions. Differential features of erythrocytic shape were defined in a small series of micropreparations vs the rest blood samples. 相似文献

Nitrates and nitrites, accumulating in toxic concentrations in soil, plants, water and foodstuffs, can cause lethal intoxication. The method of isolation, identification and quantitation has been elaborated for their diagnosis. It is based on the isolation of water and subsequent chromogenic test plus photoelectrocolorimetry. 相似文献

The results are presented of extraction of 1-methyl-3,4-dioxybenzene, 1-methyl-2,5-dioxybenzene and 4-oxybenzene acid from aqueous solutions with hydrophobic and hydrophilic organic soluvants. It is shown that the degree of extraction depends on the nature of the extragents and pH of the aqueous phase medium. Extraction multiplicity for obtaining necessary quantities of the compounds is calculated. 相似文献

By potential damage, chemical terroristic attacks are much more dangerous than terroristic bombing. To fight chemical terrorism it is necessary to create the system of medical-environmental defense of the population. In line with emergency medicine, forensic medical service is a very important element of the antiterroristic defense. The activity of forensic-medical experts in the field of terroristic chemical attack is analysed. 相似文献

Despite the recent surge in society's interest in human violence, relatively few studies have been conducted examining the closely related phenomenon of animal cruelty. Although several researchers have begun to identify some of the correlates of animal cruelty, few have attempted to understand how differences in the backgrounds of rural and urban residents have led to their abuse of animals. Using survey data from 261 inmates, the authors investigate how demographic, familial differences and species type have contributed to the frequency of acts of animal cruelty. In general, early exposure to animal abuse is a strong predictor of the subsequent behavior. However, rural inmates learned to be cruel by watching family members exclusively, whereas urban inmates learned from family members and friends. Moreover, urban inmates chose dogs, cats, and wild animals as their target animals; however, rural inmates chose only cats. 相似文献

A Re-examination of the Effects of Biased Lineup Instructions in Eyewitness Identification 总被引:1,自引:0,他引:1
Clark SE 《Law and human behavior》2005,29(5):575-604
A meta-analytic review of research comparing biased and unbiased instructions in eyewitness identification experiments showed
an asymmetry; specifically, that biased instructions led to a large and consistent decrease in accuracy in target-absent lineups,
but produced inconsistent results for target-present lineups, with an average effect size near zero (Steblay, 1997). The results
for target-present lineups are surprising, and are inconsistent with statistical decision theories (i.e., Green & Swets, 1966).
A re-examination of the relevant studies and the meta-analysis of those studies shows clear evidence that correct identification
rates do increase with biased lineup instructions, and that biased witnesses make correct identifications at a rate considerably
above chance. Implications for theory, as well as police procedure and policy, are discussed. 相似文献
