A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning. 相似文献

In a case of suicidal application of electricity differences between the rectal temperature of the body and the suspected time of death were observed.In order to answer the question whether an electric current from hand to hand over >30 min led to a rise in body temperature FEM-based computer simulations and animal experiments were carried out. Both resulted in a warming of the soft parts in the arm without warming the body core. Thus a temperature-based estimation of the time since death can also be used in cases with electricity as the cause of death. Besides, in the animal experiment we found a spontaneous rise in the body core temperature even without application of electricity which may be a reason for the typical temperature plateau after death. 相似文献

中国现行侦检关系受制于线型诉讼结构,存在诸多弊端而有待完善。但是,“侦检一体化”模式不符合中国侦检关系模式的设置,不具备实践可行性。对此,应当加强检察机关对侦查活动的监督、制约,并且对于拒绝监督与制约的,予以惩戒。同时增强辩方力量,实现审前程序控辩平衡。 相似文献

Classroom The increased use of information technology in schools is generally perceived as a positive, dynamic step into the future. By providing IT facilities for all children throughout their education we are affording them access to a wider range of career opportunities and educational experiences. Feminists have long debated the extent to which technology can be exclusionary for women because of its construction as a masculine domain, emphasizing 'masculine' characteristics of mastery, skill and control. By focusing on the music classroom, Armstrong explores gender and the compositional process and the effects of an overtly technological approach to composition. In the early part of the essay, she draws on Sherry Turkle's early work based on observations of male and female computer programmers. Despite observing a variety of computational styles Turkle concluded that, although technology allowed for this diversity, computer culture did not, noting that many females preferred a style that did not favour the canonical, plan-oriented, abstract thinkers who 'constitute an epistemological elite'. In her own research, Armstrong found that girls often became alienated from their own creative work because the culture of the music classroom appears to privilege a particular style of working. By focusing on the singing voice and the corporeal, Armstrong draws on aspects of cyberfeminism to illustrate how girls can transcend and subvert this masculine culture. 相似文献

The recent formation of a United Kingdom and Irish working group, the Body Fluids Forum (BFF), highlighted the need to investigate different working practices prior to any inter-laboratory comparison work and identification of best practice. Various dilutions of semen were seeded onto swabs and cloth samples for each BFF member laboratory to test using their standard techniques. The results showed that the detection of acid phosphatase on swabs is best achieved using direct testing rather than on an extract from the swab. Extraction methods for spermatozoa require a balance to be achieved between using a sufficient volume of water to ensure optimal release and minimal volume to ensure a concentrated extract. PSA tests were investigated and found to be more sensitive than Choline. DNA profiles were obtained from samples in which no spermatozoa had been detected during microscopic examination. 相似文献

我国商事登记立法的不足与完善 总被引:1,自引:0,他引:1
商事登记制度在我国设立多年。我国商事登记立法中存在诸多缺陷,如商事登记立法之间存在冲突,立法形式分散,法出多门等等,为此,应实行公私法分离立法模式,统一完善商事登记制度等措施,以完善我国商事登记法律制度。 相似文献
