Perfluoroalkyl substances in the blood samples from a male population of Sweden

Temporal trends of perfluoroalkyl substances （PFASs） have been determined in the blood samples from several countries globally including a female population in Sweden recently, yet little is known about the time trends in the blood levels of these compounds in Swedish male populations over recent years. In this study, the fourteen target PFASs consisted of four perfluorosulfonates （PFSAs） and ten perfluorocarboxylates （PFCAs） in the whole blood samples, collected from 153 Swedish elderly men during the period between 2008 and 2010, were analyzed via ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS/MS）. As the dominant PFASs contaminants in the blood samples, perfluorooctane sulfo- nate （PFOS） showed the highest geometric mean （GM） at 8.5 ng/mL, ranging from 1.7 to 29 ng/mL, while blood perfluorooctanoic acid （PFOA） contained the GM of 1.8 ng/mL, ranging from 0.35 to 6.4 ng/mL. Both the levels of these two compounds were lower than those determined in the blood samples of Swedish elderly pop- ulations derived from the late 1990s. According to the temporal trend analysis, over the three years, the blood levels of PFOS in Swedish male populations declined 16 % per annum, while those of perfluoroundecanoic acid （PFUnDA） increased 6.1% per annum, which were con- sistent with those reported previously for the populations from other countries.     

Nanoscale structural and electronic evolution for increased efficiency in polymer solar cells monitored by electric scanning probe microscopy

Control of blend morphology at multi-scale is critical for optimizing the power conversion efficiency （PCE） of plastic solar cells. To better understand the physics of photoactive layer in the organic photovoltaic devices, it is necessary to gain understanding of morphol- ogy and the corresponding electronic property. Herein we report the correlation between nanoscale structural, electric properties of bulk heterojunction （BHJ） solar cells and the annealing-induced PCE change. We demonstrate that the PCE of BHJ solar cells are dramatically improved （from 1.3 % to 4.6 %） by thermal annealing, which results from P3HT crystalline stacking and the PCBM aggregation for interpenetrated network. The similar trend for annealing- induced photovoltage and PCE evolution present as an initial increase followed by a decrease with the annealing time and temperature. The surface roughness increase slowly and then abruptly after the same inflection points observed for photovoltage and PCE. The phase images in electric force microscopy indicate the optimized P3HT and PCBM crystallization for interpenetrating network formation considering the spectroscopic results as well. From the correlation between surface photovoltage, blend morphology, and PCE, we propose a model to illustrate the film structure and its evolution under different annealing conditions. This work would benefit the better design and optimization of the morphology and local electric proper- ties of solar cell active layers for improved PCE.     

大众休闲健身与体育消费意识

近年来,随着经济的发展,人们越来越认识到健康的重要性,主动寻求健康的意识明显增强,健康已成为一种时尚和人们追求的目标。而在追求健康的过程中,除了饮食结构的改变,极为重要的一点就是,人们已经更多的意识到健康是可以通过各种体育锻炼来保持的,因此,人们对于锻炼的需求大量上升。作为众多锻炼形式中的一种,大众休闲健身已然成为了一项颇具实用锻炼价值、受欢迎程度较高的运动项目,影响日益扩大。同时,也因其无激烈的对抗、身体接触等原因,符合人们的消费意识,更为人们的青睐。     

地方理论视域下《管家》中的二元对立

玛丽莲·罗宾逊是美国当代著名小说家.她的作品题材大多与环境息息相关,反映了当代社会的环境问题.《管家》是她的第一部小说,国内学界对它的介绍和研究还比较匮乏.文章运用劳伦斯·布伊尔的地方理论来探讨《管家》中的二元对立.一方面,地方被人为地划分为两个互为对立的部分：人类与自然;另一方面,在人类社会内部,男性与女性处于对立状态,两性不平等现象特别严重.有鉴于此,罗宾逊希冀改变这种现状,呼吁人类突破地方局限,实现地方的统一,以最终实现人与自然之间以及两性之间的和谐共处.
