中国政府防范生物恐怖袭击对策研究

文章借鉴国外防范生物恐怖袭击对策的经验和教训,结合我国的实际情况,提出了中国政府防范生物恐怖危机的组织管理体系、法律保障机制、公共管理对策以及危机后管理等政策建议。文章系统地就中国政府建立危机管理体制进行了探索性的研究。     

水溶性壳聚糖的制备及其在化妆品中的应用

用一氯乙酸对壳聚糖进行了化学改性,将酸溶性壳聚糖转变为水溶性羧甲基壳聚糖,并对其理化性质(如取代度、特性粘度、吸湿性和保湿性等)进行了测定。结果表明,羧甲基壳聚糖具有良好的水溶性,应用在啫喱水方面具有良好的吸湿性、保湿性以及定型、护发作用。     

柔嫩艾美球虫对复方抗球虫制剂抗药性的诱导

柔嫩艾美球虫(Eimeriatenella)敏感株在复方抗球虫制剂剂量递增的情况下,经过10次传代,诱导出其对复方抗球虫制剂的抗药性;经过8次传代,诱导出柔嫩艾美球虫抗氯嗪苯乙氰株对复方抗球虫制剂的抗药性。与单一用药相比,柔嫩艾美球虫对复方抗球虫制剂的抗药性产生较慢,复方抗球虫制剂控制柔嫩艾美球虫敏感株的效果比控制抗氯嗪苯乙氰株的效果要好。

Validation of powder X-ray diffraction following EN ISO/IEC 17025

Powder X-ray diffraction (PXRD) is used widely in forensic science laboratories with the main focus of qualitative phase identification. Little is found in literature referring to the topic of validation of PXRD in the field of forensic sciences. According to EN ISO/IEC 17025, the method has to be tested for several parameters. Trueness, specificity, and selectivity of PXRD were tested using certified reference materials or a combination thereof. All three tested parameters showed the secure performance of the method. Sample preparation errors were simulated to evaluate the robustness of the method. These errors were either easily detected by the operator or nonsignificant for phase identification. In case of the detection limit, a statistical evaluation of the signal-to-noise ratio showed that a peak criterion of three sigma is inadequate and recommendations for a more realistic peak criterion are given. Finally, the results of an international proficiency test showed the secure performance of PXRD.     

扩张中的犯罪预备及参与形式——围绕第18届国际刑法学大会第一专题的展开

新的社会、经济形势下,恐怖主义及其他严重有组织犯罪在世界范围内日益蔓延,作为针对此类犯罪现象的积极调整,各国刑事立法与司法同步呈现出扩张的趋势。着眼刑事实体法层面,不难发现不同形式的预备行为及参与行为之犯罪化处遇同样有着相当的膨胀,此处结合第18届国际刑法学大会第一专题之讨论试图对该命题作进一步的展开。     

Capillary gas chromatographic analysis of illicit diamorphine preparations

An improved capillary gas chromatographic method for the analysis of illicit diamorphine preparation is reported. The method was able to resolve the impurities and more frequent adulterants and contaminants present in street heroin preparations with a diamorphine detection limit of 0.2 ng in split-less mode.     

我国犯罪预备处罚原则反思

我国刑事责任评价的时间起点是犯罪的预备行为。我国刑法以处罚预备犯为原则,有助于严密刑事法网,将犯罪遏制在萌芽阶段,充分发挥刑法预防功能,但其与现行的犯罪构成理论相矛盾,与刑法谦抑精神相违,缺乏实践操作性。刑法第22 条已经名存实亡,成为一种无意义的重复规定,建议修改刑法时予以删除,同时将一些严重犯罪的预备行为规定为独立罪名。     

民事诉讼审前准备程序的完善

审前准备程序是民事审判的重要组成部分,对于提高诉讼效率、确保民事诉讼公正具有十分重要的意义。本文以审前准备程序的程序价值为基础,通过对我国审前准备程序存在弊端的考察,提出了完善我国审前准备程序的建议。     

Recommended Practices for Macerating Human Thyroid Cartilage

Visible abnormalities on the thyroid cartilage may be indicative of perimortem trauma including fractures or sharp force trauma. During autopsy, the thyroid cartilage must be freed of surrounding soft tissue before these abnormalities can be clearly observed. Several processing methods were first experimentally tested on pig ears to narrow down which might work best to process human thyroid cartilage. Several methods in the categories of hot water maceration, chemical/enzyme maceration, and dermestid beetles were then tested on a sample of 37 human thyroid cartilages. An adapted 22-point scoring system was used to score the efficacy of each processing method. Chemical maceration using bleach was found to be the best method for removing surrounding tissue from thyroid cartilage, with Arm & Hammer^TM powdered laundry detergent as a close second. These methods are inexpensive, quick, and easy to implement, making them a simple addition to busy medical examiner’s offices or forensic anthropology laboratories.
