One hundred and twenty eight cases of shooting fatalities were investigated during an 11-year period. Of these 57% were homicidal shootings with 34% suicidal in nature. Only two suicidal fatalities were female. Analysis of the sites of entrance wounds confirmed the 'sites of election' in suicidal shootings, whilst homicidal wounds showed a much wider distribution. Multiple entrance wounds were seen in 42% of homicidal shootings. Injuries to hands were seen in 7 homicidal fatalities. 相似文献

This paper describes the recovery and identification of crew members lost during a collision at sea. On 9 February 2001, south of Honolulu, Hawaii, the Japanese fishing training boat, Ehime Maru was struck by the USS Greeneville (SSN 772), a Los Angeles-class fast attack submarine. Witnesses estimate that the vessel sank within 5-10 min after the collision. Nine of the 35 crew members remained unaccounted for after rescue procedures were completed. The U.S. Navy attempted the unprecedented procedure of moving the boat from a depth of 610 m (2000 ft) into shallower waters so that the missing could be located and recovered. Eight of the nine crew members were recovered and identified by their dental records. 相似文献

Photodegradation and laser desorption mass spectrometry (LDMS) is a powerful combination of methods capable of characterizing dyes found in pen inks. Rhodamine dyes in pens that contain red ink were analyzed directly from paper (no extraction step is necessary). Inks exposed to incandescent light form photodegradation products (compounds with lower molecular weights than that of the intact dye) and in some instances, photoproducts (compounds with higher molecular weights than that of the intact dye). The degradation products and photoproducts can be detected with LDMS, and the results can be used for dye identification. Advantages include: (1) the instrumental analysis takes less than a minute; (2) sample preparation is minimal; (3) LDMS is a minimally destructive technique; (4) incandescent light sources are inexpensive, safe to use, and readily available; and (5) isomeric dyes can be distinguished. 相似文献

利用从猪传染性胃肠炎病毒(TGEV)Miler株(M5C)克隆建立的一株重组杆状病毒(R2-2)表达的重组TGEV钉状糖蛋白(S),建立了一种阻断酶联免疫吸附试验(ELISA)来检测猪群抗TGEV抗体。试验表明,用重组病毒R2-2接种sf9细胞(spodopterafrugiperda)所表达的重组蛋白量在接种后第72h达到最高值;该重组蛋白能与抗TGEVS蛋白A位点的单克隆抗体特异性结合。用阻断ELISA检测68份来自无TGEV感染或TGEV(Purduel5)免疫的仔猪或母猪血清,结果与TGEV蚀斑减数试验完全相符,灵敏度和特异性均为100%。同时检测来自TGEV试验免疫猪、美国部分地区猪群、我国进口猪以及我国国内猪群血清627份,阳性检出率分别为82.61%、61.62%、58.33%和29.10%;用中和试验(微量中和试验或病毒蚀斑减数试验)检测的TGE血清抗体阳性率分别为80.87%、59.60%、56.11%和30.60%,两种方法对抗TGEV抗体的检出率没有显著差异。 相似文献

A case of suicidal ingestion of hydrofluoric acid is presented. Death of the victim while in police custody was one of the more unique aspects of the case. This is the sixth case of poisoning of this type reported in Dade County. Clinical, pathological, and toxicological aspects of fluoride poisoning are discussed. 相似文献
