The specific gravity and buoyancy of 98 men were calculated at various lung volumes. The data indicated that all subjects would be capable of floating in either freshwater or seawater at total lung capacity. At functional residual capacity, the value approximating the lung volume of a recently dead body, 69% of the subjects would float in seawater, whereas only 7% would float in freshwater. Results of this study indicate that while drowned bodies are more likely to sink than bodies dead of other causes, no conclusion regarding the cause of death can be made on the basis of whether bodies float or sink. 相似文献

The general toxicology unknown often presents challenges and interests to toxicologists. A systematic analytical approach to search for drugs or poisons is presented here. The preliminary screening analyses were as follows: alcohol by gas chromatography (GC), ethchlorvynol colorimetric analysis, enzyme multiplied immunoassay technique (EMIT), basic drug screening by GC, and neutral and weakly acidic drug screening by GC. Other additional analyses were performed depending on the special circumstance of each individual case and the results of these preliminary analyses. Positive findings were confirmed by computerized gas chromatography/mass spectrometry when practical. Quantitation was performed by GC whenever possible. 相似文献

The role of lay magistrates in England and Wales has been progressively undermined by protracted processes of reform over the last two decades. Current government proposals aim to reorient and ‘strengthen’ their function through the creation of new magisterial responsibilities such as oversight of out of court disposals and greater involvement with local justice initiatives. This article argues that while these proposals embody necessary and important areas for reform, taken in isolation they will fail to consolidate the role of magistrates in summary justice unless they are enacted alongside other measures which aim to reaffirm the status of lay justices, and which seek to reverse the trend which has prioritised administrative efficiency at the expense of lay justice. Rapidly declining magistrate numbers together with continuous (and continuing) programs of court closures are irreconcilable with the future viability of a lay magistracy. 相似文献

Callous-unemotional (CU) traits (i.e., lack of empathy/guilt, uncaring attitudes) are believed to be a developmental antecedent to adult psychopathy and identify antisocial youth at risk for severe and persistent aggression. The psychosocial histories of antisocial and aggressive individuals with psychopathic traits are characterized by abusive or unaffectionate parenting; however, there is a gap in the literature regarding the unique impact of these factors on adolescent offenders. The purpose of the present study was to examine the contribution of maternal warmth and affection (i.e., care) to dimensions of CU traits and aggression, after accounting for the influence of various types of childhood maltreatment. We investigated this aim in a sample of 227 urban male adolescent offenders housed in residential facilities. Results indicated that low maternal care was significantly associated with greater total CU traits and uncaring and callousness dimensions, even after controlling for the effects of various types of childhood abuse and neglect. Furthermore, there was a significant interaction between CU traits and care, such that aggression was highest among youths scoring high on CU traits who were exposed to low levels of maternal care. These findings draw attention to the importance of maternal bonding to CU traits and related aggressive behaviors among antisocial youth. 相似文献

In texts circulating in Britain in the seventeenth and eighteenth centuries, women who had sex with women were often denounced, mocked, and exiled from womanhood; one of the most common strategies was to call them hermaphrodites. There was constant slippage between concepts of sexual deviance at this time, but two ideas in particular – lesbian desire and hermaphroditical anatomy – became tightly bound into the figure of the tribade, a woman whose phallic ‘member’ (whether a prolapsed vagina or an enlarged clitoris) was thought to enable her to have penetrative intercourse with women. This essay follows the hermaphroditical tribade through children's compendia, gynaecological handbooks, neoclassical satires, love poems and anti-masturbation treatises. Though the writers were generally hostile, their debates over anatomy and motivation, and the tonal ambiguities in their treatment of these freakish heroines, make these texts rich sources for lesbian history. 相似文献

Carboxyhemoglobin (COHb) levels were determined in stored blood samples from 91 infants diagnosed to have died from the sudden infant death syndrome (SIDS) (0.59+/-0.41%, excluding one outlying value of 10.83%); 48 age-matched controls (0.53+/-0.38%); and three individuals who died from fire related causes (41+/-20%). No statistical differences in COHb levels were detected between blood from SIDS and control infants (p = 0.43). 相似文献

A general toxicology unknown case is presented to demonstrate our systematic approach. A 20-year-old male was found dead with multiple suicide notes. Overdose was suspected but substances were not known. Blood alcohol was negative. Urine was analyzed by enzyme-multiplied immunoassay technique and was negative for all drugs assayed. Urine was then extracted with ethyl acetate:hexane (1:1) at pH 10 and back-extracted into 1.0N sulfuric acid. The acidic layer was adjusted to pH 10, and re-extracted with ethyl acetate:hexane (1:1). The residue was analyzed by gas chromatography (GC) on a 3% OV-101 column. It was found to be negative for all commonly screened substances. However, several unknown peaks were observed. Electron impact mass spectra of these unknown peaks were obtained and searched for in our computer library of more than 25000 mass spectra. These unknown peaks were identified as doxylamine and pyrilamine by gas chromatography/mass spectrometry. The base peak and molecular ion for pyrilamine were at m/z 121 and 285, respectively. The base peak for doxylamine was at m/z 58. No molecular ion was observed for doxylamine. Both doxylamine and pyrilamine are antihistamines, but are promoted and used in the management of insomnia. Quantitation was performed on a GC using dexbrompheniramine as an internal standard. Blood concentrations for doxylamine and pyrilamine were 0.7 and 7.0 mg/L, respectively. Concentrations in other tissues were determined. Death was caused by combined doxylamine and pyrilamine intoxication; the manner of death was suicide. 相似文献

A variety of complications involving heart valve implants have been documented. Embolism originating from thrombosis of the valve has been a recurrent problem in mechanical and to a lesser extent porcine implants. We report two accidental deaths as a result of embolization of cotton pledgets from porcine valves. Hospital personnel failed to remove this cotton material from the valves before surgical placement. In the first case, when portions of the pledgets embolized to both carotid arteries, fatal cerebral infarction occurred. In the second case, portions of the pledgets embolized to a coronary artery producing severe left ventricular failure. 相似文献
