An Investigation into Whether or Not the Class and Individual Characteristics of Five Turkish Manufactured Pistols Change During Extensive Firing

Abstract:  In order to assess whether or not the class and individual characteristics of a firearm change over time, five different makes of Turkish self-loading pistol were tested and were each fired a large number of times. The class and individual characteristics were identified for each pistol and the first fired cartridge case was compared with the subsequent consecutive 250th fired cases for each pistol. It was found that there were slight changes in some of the individual and class characteristics; however, this was not statistically significant and did not affect the ability of the firearms examiner to match the first fired case to the last fired case for each firearm tested.     

家兔低压电击伤后血清LDH和HBDH活性变化

目的研究家兔非热低压电击伤后不同时间乳酸脱氢酶（lactate dehydrogenase,LDH）和羟丁酸脱氢酶（hydroxybutyrate dehydrogenase,HBDH）活性的变化．为I临床和法医学非热电击伤提供诊断依据。方法健康新西兰大白兔40只,随机分为对照组和电击伤后7个时间点的实验组,每组5只。实验组使用本室已建立的非热低压电击伤方法处理,电击后各实验组动物按照预定时间点麻醉后抽取5mL心室血．测定血清LDH,HBDH酶活性。结果在非热低压电击伤后家兔目标血清酶活性发生了动态变化,有一定规律性,其中LDH活性在电击伤后4、12h和1、2、3d明显升高（4、12h和1d P〈0．01;2和3d P〈0．05）;HBDH活性在电击伤后2和3d明显升高（P〈0．05）;电击组HBD肌DH比值在2、4和12h与对照组比较显著降低（P〈0．01）。结论动态监测LDH、HBDH活性,可为非热电击损伤的诊断,损伤时间推断提供理论依据。     

“入世”与我国地理标志保护

根据世贸组织的有关规则 ,我国一旦加入世贸组织 ,将无条件地承担起对其它世贸组织成员地理标志的保护义务 ,同时 ,对方也必须对我国的地理标志实行保护。然而 ,我国国民特别是工商界人士目前对“地理标志”这一概念仍比较模糊 ,保护意识淡薄。政府有关部门对地理标志的管理和保护状况也令人担忧。本文针对我国地理标志管理和保护工作的现状与存在问题 ,提出了一些相应的改进措施和建议     

中国人四肢长骨骨性标志间各段长度与总长关系的分析

利用碎裂的长骨片段 ,计算长骨的总长。选择中国人长骨 5 0 0余例 ,取其骨性标志分段测量记录 ,将测得的数据输入计算机 ,用社会科学软件包 (SPSS)中全回归法进行统计学处理。在得出的 33个多元回归方程中 ,方程1、 9、 18、 2 6证明了骨性标志间各段长度与总长的正相关关系 ,其余 2 9个方程是在有选择的略去 1个变量和因长骨近端、远端或两端缺损使 1个或 1个以上变量缺失的情况下得出。根据碎裂长骨片段骨性标志间的长度测量值 ,应用多元回归方程 ,可计算出长骨的总长

Forensic Significance of Gunshot Impact Marks on Inanimate Objects: The Need for Translational Research

Wherever an impact mark is found, either on the surface or on the recovered projectile, it is important for forensic investigators to extract useful information in solving shooting-related cases. This article reviews a collection of works on examination of impact marks upon striking of projectiles on inanimate objects, emphasizing on the retrievable information from a shooting scene and their forensic significance in shooting event reconstruction. Literature suggested that impact marks on target surfaces and the degree of deformation on striking projectiles vary according to different combinations of ammunition and surface materials. It was noted that conditions in real-case scenarios further differed unpredictably in comparison with controlled studies, where forensic investigation should be treated as case-specific basis. Furthermore, the way forensic science is researched and applied operationally has to be reconsidered to reduce the gap via translational approach for more effective use of forensic evidence.
