1细菌糖蛋白对螯虾免疫因子的影响显示文摘实验检测了气味黄杆菌的胞外糖蛋白对克氏原螯虾(Procambarus clarkii)的几种非特异性免疫困子一凝集素、酚氧化酶、溶菌、抗菌和超氧化物歧化酶等活力的影响。注射10 mg糖蛋白后,实验组螯虾血清的免疫因子活力均高于对照组,凝集素活力在第1~4天最高;酚氧化酶在第1~5天维持较高活力,最大活力在第 2天,溶菌、抗菌活力在第 1~ 6天维持较高水平,分别在第 3天、第 2天达到最大。与对照组相比,实验组螯虾肌肉的溶菌和抗菌、超氧化物歧化酶活力没有明显的变化。结果表明:气味黄杆菌的胞外糖蛋白可增强螯虾血淋巴的凝集素、酚氧化酶、溶菌和抗菌活力。莫照兰 李会荣 俞勇 王祥红 纪伟尚 徐怀恕 P.S.

2Production of pig iron from red mud waste fines using thermal plasma technology显示文摘Red mud, an insoluble residue produced during alkali leaching of bauxite, is considered as a low-grade iron ore containing 30% to 50% iron. The present paper deals with the use of thermal plasma technology for producing pig iron from red mud waste fines. The smelting reduction of red mud was carried out in a 35 kW DC extended arc thermal plasma reactor. Red mud was properly mixed with fluxes and graphite (fixed carbon, 99%) as a reductant as per stoichiometric requirement. The effect of various process parameters like a reductant, fluxes and smelting time on iron recovery was studied and optimized. An optimum condition for the maximum recovery of iron was obtained. A new thermal plasma process applicable to direct iron making from red mud waste fines that would achieve significant utilization of red mud was proposed.K. Jayasankar P.K. Ray A.K. Chaubey A.

4肝硬化中肝细胞癌的动态对比增强CT成像:根据示踪动力学模型行延迟双期检查方案的可行性显示文摘应用双期动态对比增强成像对4例肝细胞癌行CT检查.首先应用初始快速动态成像观察早期强化用以评估灌注情况,其后应用逐渐增加时间间隔的延迟成像来监测随后的组织增强表现以评估组织通透性。利用双人路双室分布参数模型来分析动态对比增强CT影像.分别评估血流量和通透性及血管内外容积分数。结果表明,半透膜分隔的双室模型能恰当地显示肝细胞癌和周围肝硬化组织的增强曲线。与背景肝组织相比,肝细胞癌的强化更早。T.S.

6危机中的美国侵权法显示文摘一、美国侵权法的结构美国侵权法始于十九世纪后半期。它的主要内容是以被告的赔偿责任为基础,将侵权法分为以下几部分:故意侵权、过失侵权和严格赔偿责任。多少年来,美国律师认为严格赔偿责任是不规则的,直到十九世纪六十年代人们才不反对无过失赔偿责任。在此我想说明一点,当今人们对故意侵权和过失侵权的区分远非令人满意,而且,这一区别仍然统治着美国侵权法的思想。P.S.阿蒂耶 袁胜华 王风垠 1988国外法学1988,,4:2

9论合同自由的衰落(1870-1970)显示文摘古典合同理论以自由市场交易为基础,将合同视为私人进行市场规划的工具,其经由合同法教科书与法理学著作而形成了一般合同法。一般合同法上的古典合同自由理论深刻地影响了司法、法律思维和政策,虽然其基础日渐崩溃但仍然具有顽强的生命力。随着政府和议会对合同自由越来越多的干预,以及古典合同模式不能有效处理外部效应问题、垄断问题和其他市场失灵问题,以及消费者无知等问题,古典合同理论意义上的合同自由在1870年至1970年间逐渐衰落了。P.S.阿蒂亚 范雪飞 2018法治研究2018,,4:2

14神经科学对哲学的重要意义显示文摘精神哲学(philosophy of mind,或译心灵哲学)问题传统研究的基础正在发生转变。早期关于认知与大脑无关的学说现在看来已站不住脚。随着神经科学揭示出更多的有关大脑的组织及动力学的方面的信息,这一点变得日益明显,即关于我们本性的理论必须考虑来自神经科学的信息。与这个进展相一致,我们期待神经科学、心理学和计算的共同研究,会更富有成效地提出以及可能大大地改革有关精神的哲学问题。P.S.丘奇兰德 景键 1989世界哲学1989,,4:2

18Structural Tuning of Low Band Gap Intermolecular Push/Pull Side-chain Polymers for Organic Photovoltaic Applications显示文摘A series of novel low band gap donor-acceptor(D-A) type organic co-polymers(BT-F-TPA, BT-CZ-TPA and BTSI-TPA) consisting of electron-deficient acceptor blocks both in main chains(M1)and at the pendant(M2) were polymerized with different electron rich donor(M3-M5) blocks,i.e., 9,9-dihexyl-9H-fluorene,N-alkyl-2,7-carbazole, and 2,6-dithinosilole, respectively, via Suzuki method. These polymers exhibited relatively low band gaps(1.65-1.88 e V) and broad absorption ranges(680-740 nm). Bulk heterojunction(BHJ) solar cells incorporating these polymers as electron donors, blended with [6,6]-phenyl-C61-butyric acid methyl ester(PC61BM) or [6,6]-phenyl-C71-butyric acid methyl ester(PC71BM) as electronacceptors in different weight ratios were fabricated and tested under 100 m W/cm2 of AM 1.5 with white-light illumination. The photovoltaic device containing donor BT-SI-TPA and acceptor PC71 BM in 1:2 weight ratio showed the best power conversion efficiency(PCE) value of 1.88%, with open circuit voltage(Voc) = 0.75 V, short circuit current density(Jsc) = 7.60 m A/cm2, and fill factor(FF) = 33.0%.Ansuman Nayak P.S.
