High performance liquid chromatographic determination of alcohols with reference to body distribution of methanol

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.

博观约取 厚积薄发——漫谈毕业论文的写作

<正> 按照规定,大学本科学生和研究生,包括博士研究生,毕业前都必须写作毕业论文.毕业论文究竟应当怎么写呢?常有同学向我提出这个问题.这使我想起了鲁迅先生写的一篇题为《作文秘诀》的文章.但这篇文章并不是真正告诉人们以什么作文的"秘诀",而恰恰是指出作文并没有什么"秘诀";所谓"秘诀",无非是写作时装腔作势,故弄玄虚,用某种障眼法吓唬人、愚弄人罢了.那么,作文就没有什么要注意的么?当然也有.用鲁迅的话说,那就是"有真意,去粉饰,少做作,勿卖弄".我想这道理同样适用于写作毕业论文.     

关于公文美学的思考

公文因实用而产生,又为实用而写作,具有实用美的审美价值.公文体式要求的规范化、内容的规范化和语言的规范化是公文的审美特征所在.     

An Empirical Investigation into Measurement and Determinants of Food Security

We examine the association between calorie-based indicators and experiential indicators of food security using data from slum households of Kolkata surveyed in 2010–2011. Experiential indicator is constructed following the United States Household Food Security Survey Module. Calorie based indicator is constructed using household-specific calorie norms. Modelling techniques take account of potential endogeneity in the relationship. The two indicators are aligned in the same direction implying more accurate targeting. However, there is a lack of one-to-one correspondence between the two measures and the drivers of calorie deprivation and food insecurity also differ, suggesting a one-size-fits-all policy cannot address both concerns simultaneously.     

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Job Expectations and Career Goals of Title IV-E Child Welfare Social Workers with Varying Levels of Work Experience: How Do They Differ?

A comparison of three groups of Title IV-E child welfare workers revealed significant differences among all groups on job expectations and career goals. New workers reported most positive expectations for their jobs, and greatest interest in child welfare careers and in pursuing educational goals. Seasoned workers expressed least positive expectations and least interest in future child welfare careers and educational goals. Findings may assist universities in student selection and curriculum. Child welfare agencies may benefit in areas of recruitment, training, and policies. Realistic job previews might moderate high expectations for new workers and reduce unmet expectations for experienced workers.
