Wounds of high‐energy centerfire rifles and shotguns represent distinctive injuries of forensic importance. Previous studies of contact wounds have shown variability in the potential of these weapons to produce bursting wounds of the head. The present study analyzed contact head wounds owing to 26 centerfire rifles and nine shotgun slugs and compared them with respect to weapon, ammunition, entry wound site, and projectile kinetic energy. The bursting effect, defined for this study as disruption of at least 50% of the head, occurred in 25/35 of cases and was related to kinetic energy. Bursting was associated with energies <2700 ft‐lbs in 12/22 cases and energies >2700 ft‐lbs in 13/13 cases. The volume of gunpowder gas injected into the wound was considered as contributing to the bursting phenomenon. There was no relation of bursting to the specific entrance wound site, type of ammunition, or projectile fragmentation. 相似文献

This study presented a Ferris wheel accident case. A Ferris wheel is composed of many parts, and the outmost ring of it is assembled using a lock pin. This accident occurred because the lock pin caught the door of a gondola and the gondola overturned. Five of the seven passengers in the gondola fell to the ground, along with the gondola's viewing window. The investigation revealed that the gondola became stuck when its door was caught by a lock pin at the Ferris wheel's three o'clock position. The contact between the door and the lock pin was due to a structural problem: There was not enough space allotted between the door and the lock pin. Therefore, if a passenger pushed on the gondola's door, the potential existed for contact between the door and the lock pin. 相似文献

For highly degraded DNA samples of forensic casework, new miniSTR systems have been developed to supplement the current STR systems. In the present study, nine miniSTR loci were analyzed in 300 unrelated Koreans using three multiplex PCR systems (multiplex I: D10S1248, D14S1434 and D22S1045; multiplex II: D1S1677, D2S441 and D4S2364; and multiplex III: D3S3053, D6S474 and D20S482), and allele frequencies and forensic parameters were calculated. These data demonstrated that D10S1248, D2S441, D22S1045, D14S1434, and D6S474 are as highly informative as the CODIS STRs suggesting that the miniSTRs could be useful for forensic analysis of degraded DNA. 相似文献

Testing for drugs in oral fluid is a convenient procedure for determining recent drug use. A number of issues are still to be resolved and this paper investigates the effects of storage systems on drug stability and recovery using three different collection devices supplied by Cozart, Immunalysis and Microgenics (third party). Drugs were analysed using a range of immunoassay systems followed by MS confirmation and quantitation. The reproducibility of the weight of specimen collected was excellent (CV<10%) for the three collection devices tested. Of the three systems studied, only the Cozart product gave acceptable recovery of THC from drug-spiked oral fluid. A combination of Cozart, Immunalysis and Diagnostix immunoassays with the Cozart collection system gave the most sensitive and discriminating screening assays for the drugs studied, namely THC, benzodiazepines, methamphetamine and morphine. Storage at either 5 degrees C or room temperature had no significant effect on drug recoveries. 相似文献

Abstract: An investigation is presented of the explosion of a CNG (compressed natural gas) fuel vessel, called a liner, in an urban bus. The explosion happened at a gas station 10 min after filling was completed. There were no traces of soot and flames at the failed liner, which would be indicative of explosion by ignition of the gas. The filling process of the station was automatically monitored and recorded in a computer. There was no unusual record of the filling system that indicated excess pressure at the time of the accident. There were cracks on the liner that were initiated at the outer surface of the cylindrical shell located at a point 4 cm above the lower dome where cracks did not originate easily as a result of overload. Chemical analysis was performed on a specimen that was cut from the liner, and there was no peculiarity in the mix. Mechanical analysis was performed on the specimens and showed that the hardness was not in the specified range because of inadequate heat treatment of the metal. The hardness of the liner was strictly controlled in the manufacturing process. All the liners that were manufactured at the same period with the failed liner were recalled for examination. 相似文献

Using a unique data source of genealogies of upper-status families, called Bulcheonwye families, we assess how the extent of family succession through adoption changed over five centuries from 1450 to 1949 in Korea. Our analysis shows the continued increase in the share of adopted sons among total family successors up to the end of the 19th century when three out of ten family successors were adopted. The trend of the increasing role of adoption is closely related to the declining number of sons per family, suggesting that not only the rising influence of Confucian culture but also demographic changes increased the demand for adoption. Finally, our comparison provides evidence that the likelihood of achieving high social status was significantly higher among adopted sons than biological ones, suggesting that the socioeconomic potential of adopted sons could be an important factor for adoption decision. 相似文献

This study explores how women’s functional limitations resulting from domestic violence lead to police involvement. Examining
functionality is a broader approach to exploring domestic violence outcomes than looking at injuries or impairments, and in
this study we look at the social participation aspects of social functioning. One hundred eleven battered women in four metropolitan
cities in the U.S. participated in anonymous telephone surveys. Approximately 80% of the battered women in the sample were
involved with the police due to their experiences of domestic violence. Women’s functionality was significantly associated
with battered women’s police involvement after controlling for socio-demographic and violence-related covariates. The current
study identifies one aspect of women’s functioning–social participation–as a critical predictor of their seeking of help from
the police, and suggests implications for practice, including the need for police and domestic violence agencies to have awareness
of the concept of functional limitations within a broader context of understanding disability. 相似文献
