GC-subtyping was carried out on blood stains, that had been made on glass and stored under room temperature-conditions. Using isoelectric focusing in polyacrylamide gel, followed by transfer to nitrocellulose membrane by semi-dry-electroblotting and detection with enzyme-linked antibody complex the GC-detection was possible even after 64 days. Methodical problems are discussed.  相似文献

It is widely known that inhalation of the solvent dichloromethane can lead to severe intoxication. We report on a fatal accident of a 29-year-old painter. He had to remove the old chlorocaoutchoucpaint of two overflow pools adjoining an empty swimming pool by sand-blasting. After obviously having finished his work in the first pool the painter was found dead, lying on the floor of the second pool. Later an almost empty 10-kg-canister of a paint stripper (macerating agent) the main component of which was dichloromethane was found in the car of the painter. Blood samples of the corpse measured by head space gas chromatography and electron capture detection showed dichloromethane levels in the range of 513-773 micrograms/ml.  相似文献

In order to understand the precursors to sexual offending among youth and the associated gender differences, the records of 813 sexually abusive children (659 boys and 154 girls) referred for an evaluation of their sexually inappropriate and coercive behavior were reviewed and coded. These children ranged in age from 3 to 18 when they committed their first hands-on offenses. All were under the care of the Massachusetts Department of Social Services either prior to or as a result of their behavior. Principle findings included: (1) a high proportion of girls (19 percent) in a sample of children flagged as sexually abusive to other children, (2) an exceptionally high base rate of severe maltreatment and associated clinical and psychiatric sequelae, and (3) girls were significantly more likely to be sexually abused, and when sexually abused the abuse lasted longer, was more severe, and involved more perpetrators. In addition, the girls were significantly more likely to witness domestic violence and to witness sexual deviance within the home. For all other types of abuse, there were no group differences, and (4) all of the children were subjected to a very high level of caregiver instability.  相似文献

This paper analyzes the legal issues surrounding defendants' liability for property value diminution caused by stigma from environmental contamination. The courts, law review articles, and public policy analyses are in disagreement over how to handle stigma damages. This paper argues that a reasonable risk of contamination is not required for a nuisance claim if community effects, which were caused by the contamination, are present. The authors then turn to issues regarding the level of damages and propose a methodology for measuring compensation that is based on a guaranteed sales price. This methodology is applied to the RSR smelter in Dallas, Texas.  相似文献
