An investigation into the use of calculating the first derivative of absorbance spectra as a tool for forensic fibre analysis.

A range of fibre samples was measured using J&M MSP400 and J&M MSP800 microspectrophotometers across the visible and UV/visible wavelength ranges respectively. The first derivative of the absorbance spectra was then calculated and studied. When the absorbance spectra produced for some samples were broad and featureless, the first derivative spectra provided more points of comparison that facilitated discrimination. For many of the samples, calculating the first derivative did not result in any additional discrimination due to the high number of points of comparison present in the absorbance spectra. However, for the samples that exhibited a high level of intra-sample colour variation (e.g. through uneven dye uptake common in cotton and wool, etc.), which was evident in the absorbance spectra, the associated first derivative spectra highlighted this variation between the fibres and could potentially have resulted in false exclusions. The results show that whilst calculating first derivative can be a useful aid in the comparison of spectra, a high degree of caution is required when applying this method to fibres which exhibit a large intra-sample variation in colour.

Peak blood-ethanol concentration and the time of its occurrence after rapid drinking on an empty stomach

Healthy men, 20 to 60 years old, drank a moderate dose of ethanol in the morning after an overnight fast. They consumed either neat whisky in amounts corresponding to 0.34, 0.51, 0.68, 0.85, or 1.02 g of ethanol per kilogram of body weight or 0.80 g/kg ethanol solvent diluted with orange juice. The peak blood-ethanol concentration (BEC) increased with the dose administered, but the time required to reach the peak was not markedly influenced over the range of doses studied. At a dose of 0.68 g/kg, the peak BEC ranged from 52 to 136 mg/dL (N = 83), and slow absorption (a late-occurring peak) produced a lower peak BEC. The peak BEC was reached between 0 and 45 min for 77% of the subjects (N = 152) and between 0 and 75 min for 97% of them. The time of peaking in venous blood occurred, on average, 10 min later than in capillary (fingertip) blood although the peak BEC was not appreciably different; the mean venous BEC was 97.0 mg/dL (range, 76 to 112 mg/dL), and the mean capillary BEC was 99.6 mg/dL (range, 75 to 123 mg/dL). When subjects drank 0.80 g/kg ethanol diluted with orange juice over 30 min, the average BEC increment between the end of drinking and the peak was 33 mg/dL (range, 0 to 58 mg/dL). The rate of absorption of ethanol was 1.78 mg/dL/min (range, 0.52 to 4.8 mg/dL/min), and the peak BEC occurred within 60 min after the end of drinking in 92% of the trials. The largest BEC increment (mean, 21 mg/dL; range, 0 to 44 mg/dL) was seen during the first 15 min after the drinking period.     

Clean Energy Development and China’s Climate Change Bargaining Position:Industry Policy,Innovation and Business Power

<正>This paper analyses developments in China's climate change diplomacy from the perspective of business power and conflict theory.It does so by:(i) accounting for the processes of clean energy industry policy and development in China;(ii) introducing the concept of business power and placing it in the context of climate change;(iii) applying the business power concept to China explore how the development of clean energy industry is expanding China's policy options and changing its bargaining position;and(iv) taking stock of developments thus far and assessing future prospects.It will thereby test both the theoretical proposition that the business power concept is applicable to the Chinese situation,and the empirical proposition that the ongoing development of the national clean energy sector is crucial to China's bargaining position at the international level.

不一样的“革命”——曾朴译《九十三年》

曾朴不仅是晚清知名小说家，也是近现代文学史上一位重要的文学翻译家。1912年辛亥革命后，曾朴从法语翻译了雨果的名作《九十三年》，并将其题为“法国革命外史”，刊载于《时报》。曾朴于此时翻译《九十三年》，虽然明显地包含着应合中国革命时局的动机，但作品高扬人性的主题却超越了单纯的政治革命，表达了“诗人”的革命理想。译者曾朴的“诗人”身份以及他对作品的细致解读又使他进一步阐发了作品“不失其赤子之心”的人道主题，因此使这部小说在当时显示出一种“不合时宜”的思考革命的理路。
