Y-chromosome STR haplotypes in Córdoba (Argentina)

Eight Y-chromosome STRs were investigated in a male population sample from Córdoba region (Argentina). Complete Y-chromosomal STRs haplotypes were obtained in 100 individuals, among which 91 different haplotypes were observed. The most common haplotype was shared by 4% of the sample, while 86 haplotypes were unique. The gene diversity was 0.9875 and the discrimination capacity was 0.8600. The combined polymorphism provides a powerful discrimination tool for routine forensic applications.     

A potential metallographic technique for the investigation of pipe bombings

This study was conducted in an attempt to develop a metallographic method for the investigation of pipe bombings. Three common pipe materials, ASTM A53 steel, AISI 304L stainless steel, and 6061-T6 aluminum, were shock-loaded using five high explosives and three propellants. The explosives used were ANFO, Composition C4, C6 detasheet, nitroglycerine-based dynamite, and flake TNT. The propellants used were FFFFg black powder. Red Dot smokeless powder, and Turbo Fuel A. The post-blast microstructure, hardness, and, in the case of 304L, transformed martensite content were examined for each test. The damage done to the microstructure was found to increase with increasing detonation velocity of the explosives and increase in pressure generated by the shock-metal interaction. Material hardness and, in the case of 304L, martensite content showed a sharp increase followed by a plateau as the shock pressure and detonation velocity increased.

知识产权担保融资的可行性探讨

知识产权是一种新型的可用来融资的有潜力的资产。从理论上分析,知识产权担保具有融资的可行性,实务中也有成功案例,但总体上属于探索实验阶段。尽管我国已有相关的法律、地方法规和政策,但如何使知识产权担保融资成为可行的法律制度仍是亟待解决的问题。     

警察违法犯罪行为心理探析

警察违法犯罪是具有警察身份的人实施的违法犯罪行为。影响警察违法犯罪的心理因素有行为人自身的人格缺陷、社会角色因素、归因偏差、不合理的认知以及职业特性造成的心理变化等方面。     

沉默诈欺构成论

沉默在特定情形下可以构成诈欺已成各国共识.对于沉默诈欺的构成,大陆法系国家在审判实践中形成了构成要件主义,规定了沉默构成诈欺的三个要件;英美法系则规定沉默只有在四类具体的合同中才能构成诈欺.尽管如此,两大法系均将告知义务的存在作为沉默构成诈欺的首要前提.我国的沉默诈欺制度既未明确告知义务这一前提,对诈欺故意的认定亦过于严苛,须借鉴大陆法系的一些做法对之予以修正.

Permanent Land-based Facilities for Tourism in Antarctica: The Need for Regulation

Antarctica is often described as one of world's last wildernesses. For a very long time, its isolation from human settlements provided an effective protection from intensive human visitation; however, over the past two decades, human activities in Antarctica – in particular tourist activities – have grown and diversified rapidly. In view of environmental and other concerns, regulating Antarctic tourism has become one of the major issues of debate within the Antarctic Treaty System. One of the questions that has received much attention since 2004 is the question of whether additional measures are needed to regulate (e.g. prohibit) the future development of permanent land-based facilities (such as hotels, visitor centres, logistic facilities) for tourism in Antarctica. A number of State governments involved in the Antarctic Treaty System have proposed to prohibit such developments; however, the question has not yet received a clear answer.
After a brief introduction to the Antarctic Treaty System, this article provides a definition of permanent land-based facilities for tourism and an overview of current and past land-based tourism facilities in Antarctica. Next, the question of whether such facilities are likely to further develop in the near future is discussed and an inventory is made of arguments for and against such developments. Environmental issues will be discussed first, followed by other considerations. Based on this information, a number of regulatory options are described for consideration by policy makers. The authors argue that there is a need for regulating permanent land-based tourist facilities in Antarctica and in the conclusion of this article they express their views in respect of the most favourable option.     

国际生物质能源发展对中国的启示

发展生物质能源是应对国际能源危机的重要途径.本文由国际生物质能源的发展格局出发,分别从美欧及巴西等生物质能源大国发展动机和支持体系两个角度,对国际生物质能源的发展进行了评价.分析表明生物质能源大国的真正发展动机各不相同,扭曲的动机和多元化的支持体系使得国际粮食安全受到较大的影响.这也对中国的生物质能源发展提出了新的挑战.
