Forensic Analysis of Cigarette Ash—Brand Determination Through Trace‐metal Analysis

The information inherent in cigarette ash in the form of trace‐metal concentrations may be of use in a forensic context as it can indicate the brand from which the ash originated. This knowledge might help place suspects at crime scenes or determine how many people may have been present. To develop and test statistical models capable of classifying ash samples according to brand, commercial cigarettes procured in the U.S. and overseas were “smoked” using a peristaltic pump, mimicking the range of human smoking habits. Ash samples were digested in a mixture of nitric and hydrochloric acid applying microwave digestion and analyzed using inductively coupled plasma‐mass spectrometry. Principal component analysis of the elemental data showed intrinsic differences between brands. Partial least squares‐discriminant analysis demonstrated that brand classification yields good sensitivity and specificity for a number of models tested. Varying smoking parameters did not impact the classification of ash samples.     

关于常见树皮浸提物的荧光光谱分析

近年来随着微量物证鉴定技术水平的提高,微量物证在各种案件的侦破过程中发挥出越来越重要的作用。树皮是在凶杀、盗窃、毁坏树木、交通事故案件中常见的一种微量物证。文章利用荧光光谱法、一阶导数荧光光谱法对常见树皮的浸提物进行了分析。结果表明,不同树种树皮浸提物的荧光光谱图呈现的峰数、峰位及峰形有一定的差异;一阶导数光谱图中正、负峰的峰数及振幅值的比值差异显著,从而确定了利用荧光光谱法鉴定树皮种类的依据。

论存款所有权的归属

本文结合两大法系关于存款所有权归属的法律及理论,分析了存款所有权归属存款人的观点在理论和法律运行中的诸多矛盾,认为存款所有权归属于银行,才能为银行运用存款衍生的其他金融关系建构合理的逻辑前提。     

痛风宁部分提取物对黄嘌呤氧化酶的抑制作用

目的 观察痛风宁部分提取物对黄嘌呤氧化酶(xanthine oxidase, XOD)的影响及抗氧化作用。方法 通过XOD催化黄嘌呤产生尿酸，采用铁氰化钾还原法测定还原力，分别测定各提取物对反应体系吸光度的影响。结果 秦皮乙酸乙酯提取物和秦皮乙醇提取物及威灵仙乙酸乙酯提取物对XOD的抑制作用最强，威灵仙乙酸乙酯提取物的还原能力最强。
