基于案例库在“固体废物处理与处置”教学过程中的应用研究

固体废物既是污染物质的源头也是其归宿,其处理处置涉及水、空气及土壤污染。"固体废物处理与处置"课程本身是一门交叉性非常强的专业技术课程,具有内容繁多、理论性强、学时短等特点。本文结合本科课程"固体废物处理与处置"的内容及特点采用案例互动教学方法对教学的具体实施过程、实施效果及需要注意的问题进行具体分析,以提升课程教学内容的丰富度、提高学生实践能力为目标,创建培养人才新模式。     

浅谈玻璃生产线热端设备安装前期准备

氨基废水预处理研究

针对氨基废水的成份和特性，进行了废水静置分离、萃取、加尿素除甲醛、蒸馏脱醇等预处理试验。目的是回收废水中的可利用成份，同时降低废水中的CODcr浓度。根据试验结果，提出了在碱性条件下直接蒸馏脱醇是可行的。既可回收醇5％～7％左右，又能去除CODcr达80％以上。     

晚期子宫内膜癌治疗方法与预后分析

目的:探讨晚期子宫内膜癌临床特征及预后相关因素.方法:回顾性分析我院1995.1～2005.1月间收治的39例晚期子宫内膜癌患者临床病理资料和随访结果.结果:①39例患者中,Ⅲ期25例(64.1%),Ⅳb期14例(35.9%);手术治疗35例,单纯放疗3例,单独孕激素治疗1例;5年生存率21.8%.结论:子宫浆膜受侵、子宫外多处癌灶、宫旁组织受侵犯、宫旁淋巴管或血管有癌栓及淋巴结癌转移仍是影响晚期子宫内膜癌预后的重要因素,Ⅳ期患者易盆腹腔复发和肺转移,预后更差.     

中国文化与他者文化的冲突与融合——从电影《刮痧》谈起

通过电影《刮痧》里许大同一家在异乡美国的工作、生活经历,阐述了中国文化与他者文化在"治病还是家暴、情感还是法理、面子还是侵权"等方面存在的矛盾和冲突,探讨达成文化主体间际性的一些策略,如角色的重新定位、文化移情的培养以及和而不同的接纳,提出了在他者文化环境下华裔一族文化身份认定的重要性,以及在文化日益全球化的背景下,不同民族间的文化既要沿袭传承,又要与他者文化相互理解、共存互补、走向多元、创新发展的看法。     

CASS工艺污水处理监控系统设计

影视欣赏与跨文化交际教学

大部分人对于跨文化交际教学中的电影教学存在一个共同误区,认为电影是一个传授手段,利用影片教学就是放放电影,其效果十分有限。而实际上,如果我们把影片视为一个实践手段,一个自我评估手段,影片教学这个方法的效果也许不是那么有限。在教学进行到一定程度的时候播放了《刮痧》这部影片,学生运用所学知识对此进行跨文化差异分析,把影片教学当作一个实践手段和评估手段,不仅解答了学生对与该课程实际意义的困惑,而且进一步激发了学生学习跨文化交际学的兴趣。     

Investigating the potential of using acoustic frequency on the degradation of linear alkylbenzen sulfonates from aqueous solution

The effectiveness of using acoustical (sonochemical) reactor for degradation of linear alkylbenzen sulfonate (LAS) from aqueous solution was investigated. LASs are anionic surfactants,found in relatively high amounts in domestic and industrial wastewaters. In this study,experiments on LAS solution were performed using methylene blue active substances (MBAS) method. The effectiveness of acoustical processor reactor for LAS degradation is evaluated with emphasis on the effect of treatment time and initial LAS concentration. Experiments were performed at initial concentrations of 0.2,0.5,0.8 and 1.0 mg/L,acoustic fre-quency of 130 kHz,applied power of 500 W and temperature of 18 °C～20 °C. At the conditions involved,LAS degradation was found to increase with increasing sonochemical time. In addition,as the concentration increased,the LAS degradation rate de-creased in the acoustical processor reactor.     

试论中国古代官吏致仕制度

古代官吏退休称为“致仕”。致仕制度伴随封建官僚任命制的出现而产生 ,它最初形成于汉代。之后 ,历代王朝相互承袭 ,并不断予以发展和完善 ,最终形成以“年龄、身体状况、品级”三大条件为主要依据的古代官吏致仕制度。封建君主通过“升官晋阶、参听朝政、恩荫子孙、特殊礼遇、给予俸禄、赐物”等六方面的措施 ,基本能有效安置致仕官吏 ,使官员队伍的新陈代谢得以顺利进行 ,达到巩固统治的目的。但由于时代局限 ,致仕制度也存在一些不足之处。诸如 ,主要施用于高级官吏 ,受皇帝个人意志左右 ,未能形成严密的体制等等。     

Effectiveness of specific factors in community-based intervention for child-witnesses of interparental violence: A randomized trial

A community-based intervention with specific factors for children and parents exposed to interparental violence (IPV) was compared with a control intervention based on non-specific factors. We hypothesized that participation in an intervention with specific factors, focused on IPV, parenting and coping, would be associated with better recovery. IPV exposed children and parents were group randomized over a specific factors- and control intervention. Baseline, posttest and follow-up measurements of 155 parents and children (aged 6–12 years, 55.5% boys) were fitted in a multilevel model. Outcomes were parent and teacher reported children's internalizing and externalizing problems (CBCL, TRF), child self-reported depressive symptoms (CDI) and parent and child reported children's post-traumatic stress symptoms (TSCYC, TSCC). Based on intention-to-treat and completer analyses, children in the specific factors intervention did not show better recovery than children in the control intervention. Children in both interventions decreased significantly in parent-reported children's internalizing and externalizing problems and post-traumatic stress symptoms. Children reported a decrease in their mean level of depressive and post-traumatic stress symptoms. Teachers reported a decrease in internalizing problems, but not in externalizing problems. No association between time since exposure and level and course of symptoms was found. Treatment differentiation was assessed and both programs were significantly different on hypothesized effective factors. Higher treatment adherence in both programs did not result in a larger difference in recovery. IPV exposed children improve over the course and after participating in a community-based child- and parent program, but specific factors in intervention may not carry additional benefits when implemented in community settings.
