Simple and simultaneous quantification of cyanide,ethanol, and 1-propanol in blood by headspace GC–MS/NPD with Deans switch dual detector system

Cyanide is a powerful and rapidly acting poison. In Japan, cyanide poisoning is rare, and regular cyanide testing can be costly and time consuming. In contrast, alcohol analysis is routinely performed in most forensic laboratories. In this study, we attempted to develop a method for the simultaneous quantification of cyanide and alcohols in blood using headspace gas chromatography (HS–GC). As nitrogen-phosphorus detection (NPD) is more sensitive to hydrogen cyanide than mass spectrometry (MS), a Deans switch was used to switch the detectors during a single run. The separation provided by three analytical columns, PoraBOND Q, CP-Sil 5 CB, and HP-INNOWax, was investigated, and PoraBOND Q was selected. The use of HS–GC–MS/NPD with a Deans switch enabled the simple and simultaneous quantification of cyanide, ethanol, and 1-propanol. Eighteen other volatile compounds were detected in the SIM/scan mode of the MS.     

论外商投资合同法律效力争议解决

本文所称外商投资合同法律效力争议,是一个较为宽泛的概念,它不仅包括外商在中国境内直接投资签署的中外合资/合作经营企业合同及其变更的法律效力所产生之争议,也包括外资并购合同法律效力产生之争议,还包括外商投资中企境外企业所签署的合同法律效力所产生之争议。本文意图通过对上述三种不同形式的外商投资合同法律效力所产生之争议的不同方面进行比较研究,从而找出正确的解决这些争议的方法,以供业内人士、仲裁员、律师参考。     

汽车玻璃贴膜紫外及可见光谱特性检验的物证价值

目的通过对汽车玻璃贴膜紫外、可见光谱特性的检验,研究其对汽车玻璃物证检验的辅助作用,证实其物证价值。方法应用紫外、可见分光光度计对55个品牌,不同型号汽车贴膜的光谱特性进行测试。结果 55个不同品牌、不同型号贴膜紫外截止波长、吸收峰数、紫外可见吸收曲线都是有差异的。结论贴膜可以通过测试紫外、可见光谱进行区别及比对检验,弥补玻璃检验的不足,起到辅助玻璃区别认定的目的。

The Impact of Gender and Department Climate on Job Satisfaction and Intentions to Quit for Faculty in Science and Engineering Fields

This study investigates whether gender and the perceptions of department climate affects faculty job satisfaction and intentions to quit (work outcomes) with surveys responses from 308 faculty members in science and engineering fields. The study finds that both gender and department climate are related to work outcomes and that two facets of department climate (affective and instrumental) mediate the relationship between gender and both job satisfaction and intention to quit. This finding suggests that universities can benefit from improving department climate, which then may improve the retention of both male and female faculty, but may have an even greater impact on improving job satisfaction and reducing intentions to quit of female faculty.
