作为宗教、医疗及艺术的表述载体——彝族诺苏人“尼此裹”治疗仪式的文化解读

“尼此裹”仪式作为最为典型、实践率最高的传统宗教医疗方式,在彝族诺苏支系群体的心目中有着不可替代的地位。它不仅体现出诺苏文化宗教信仰体系的核心价值观念,也承载着诺苏人寻医问药、解除疾病痛苦的基本身心需求,更传递出诺苏文化中艺术表达方式独特的一面。因此,“尼此裹”治疗仪式应该被视为一种重要的非物质文化遗产表述载体而加以重视。     

倪瓒诗文考析

列出画史上"元四家"之一的倪瓒诗文集的7个主要版本.明天顺荆溪蹇刻七卷本《倪云林先生诗集》,为倪云林诗文集之祖本;清康熙城书室刻十二卷本《清閟阁全集》,为倪云林诗文集最完善之本.而著录于《石渠宝笈续编》中《云林画谱》为倪瓒所作的可能性很大.

铁凝作品研究综述

铁凝研究已有近三十年的历程,文本研究、作家主体研究及方法论研究都取得了丰厚的研究成果。早期零散、单篇作品随笔式的印象主义解读逐渐走向了宏观与微观相结合的整体化、多样化的研读,研究视阈从闭锁走向了开放,研究格局也从单一走向了多元。但仍存在诸多问题,研究个体的主体性缺失或湮没,研究向度或方法的偏离与倾斜,研究存在争议或不够深入。     

Science Letters:Dechlorination mechanism of 2,4-dichlorophenol by Ni/Fe nanoparticles in the presence of humic acid

To understand the feasibility of its application to the in situ remediation of contaminated groundwater, the dechlori-nation of 2,4-dichlorophenol (2,4-DCP) by Ni/Fe nanoparticles in the presence of humic acid (HA) was investigated. We found that, as high performance liquid chromatography (HPLC) was used, the 2,4-DCP was first quickly reduced to o-chlorophenol (o-CP) andp-chlorophenol (p-CP), and then reduced to phenol as the final product. Our experimental results indicated that HA had an adverse effect on the dechlorination of 2,4-DCP by Ni/Fe nanoparticles, as the HA concentration increased, the removal rate decreased evidently. It also demonstrated that 2,4-DCP was reduced more easily to o-CP than to p-CP, and that the sequence of the tendency in dechlorination of intermediates was p-CP>o-CP. Transmission electron microscope (TEM) showed that HA could act as an adsorbate to compete reactive sites on the surface of Ni/Fe nanoparticles to decrease the dechlorination rate. Also we con-cluded that the dechlorination reaction of 2,4-DCP over Ni/Fe nanoparticles progressed through catalytic reductive dechlorination.

Foam separation of chromium (Ⅵ) from aqueous solution

Removal of chromium (Ⅵ) dissolved in water by intermittent foam separation was implemented with cetyl trimethy-ammonium bromide as surfactant. The influence of various factors on removal efficiency was systematically studied. The removal efficiency has a maximum value near pH 4.0; thus, most experiments were carried out at pH 4.0. The orthogonal experiment was conducted to confirm the optimal operating parameters. The orthogonal experimental results show that when the liquid feed concentration is 10 mg/L, the pH value of feed solution is 4.00, air flow rates 0.9 L/min, surfactant dosage is 300 mg/L, the maximum removal efficiency of chromium (Ⅵ) reaches 97.80%, and condense multiple reaches 1711. The kinetic test indicates that the foam separation of chromium is a first-order process. The equivalent rate constant calculated from the slope is 0.406 4, and the equivalent rate equation is obtained.

爱尔兰母亲或大母神——叶芝剧作《胡里痕的凯瑟琳》中的民族精神悖论

《胡里痕的凯瑟琳》是叶芝最重要的剧作之一,也是爱尔兰民族戏剧运动的一座里程碑。本文通过对该剧文本和历史语境的分析,集中阐发了在这一政治文化意象中凝聚的爱尔兰民族精神悖论：作为爱尔兰母亲,她召唤民族之子献身于爱尔兰的解放事业;作为大母神,她又不断地煽动狭隘、事仇的民族主义情绪和暴力的群众政治。正是这一民族精神悖论,培育了叶芝对爱尔兰的矛盾情感,并影响他创造性的生命轨迹和个人的情感历程。
