Treatment and hydraulic performances of the NiiMi process for landscape water

This paper describes the NiiMi process designed to treat landscape water. The main aim of the research was to investigate the feasibility of NiiMi for removing organic and nutriment materials from landscape water. During the batch-scale NiiMi operation, the removal rates of color ranged from 66.7%o-80% , of turbidity from 31.7%-89.3%o, of chemical oxygen demand （COD） from 7%-36.5%, of total phosphor （TP） from 43%-84.2%, of soluble phosphate from 42.9%-100%, of total nitrogen （TN） from 4.2%-46.7%, and of NH4^＋-N from 39.3%-100% at the hydraulic loading of 0.2 m^3/（m^2·d）. Results showed that the removal efficiencies of COD, TP, soluble phosphate and TN decreased with the decline in the temperature. The NiiMi process had a strong shock loading ability for the removal of the organics, turbidity, TP, soluble phosphate, TN and NH4^＋-N. Three sodium chloride tracer studies were conducted, labeled as TS 1, TS2, and TS3, respectively. The mean hydraulic retention times （mean HRTs） were 31 h and 28 h for TSI and TS2, respectively, indicating the occurrence of a dead zone volume of 12% and 20% for TS 1 and TS2, respectively. TS 1 and TS2 displayed the occurrence of short-circuiting in the NiiMi system. The comparison results between TS1 and TS2 were further confirmed in the values obtained for some indicators, such as volumetric efficiency （e）, short-circuiting （S）, hydraulic efficiency （2） and number of continuously stirred tank reactors （N）.     

谈技校化学教学常用的教学方法

教学方法的选择与应用会对教学效果带来直接的影响。在长期从事技校化学教学过程中，除运用常见的课堂讲授外，还针对技校生的特点、化学课的课程特点，大胆采取了直观教学法、指导学生自学、练习法、实验法以及现场参观学习法等多种行之有效的教学方法，收到了较好的教学效果。由此得出结论：只有将多种教学方法结合在一起灵活运用，才能使教学过程生动有趣，做到“寓教于乐”，从而取得理想的教学效果，更好地提高化学教学质量。

孔子和孟子“仁”论浅析

儒学作为封建社会占统治地位的思想,有其精华和糟粕。我们的态度不是“厚古薄今”,而是“古为今用。”为了充分发掘中国古代优秀传统文化的精髓。作者拟采用纵横对比的方法,试图就孔、孟“仁”论各自的特点和共同的方面进行对比,以挖掘我国传统文化的一些精髓,为推动儒学思想的研究做一点贡献。     

基于服务地方的广西普通高校本科专业设置与建设的思考

专业建设是人才培养的基础。坚持服务地方,优化学科专业结构,建立适应和促进地方经济发展的学科专业体系,是地方高校教育改革的方向。近年来,广西普通高校的本科专业建设虽然取得了一定成效,但也存在一些不容忽视的问题。本文立足于广西高校学科专业设置必须坚持服务地方的宗旨,通过对广西普通高校专业设置种类、结构布局、建设水平等方面存在的问题分析,提出了加强和改进广西普通高校本科专业设置和建设的建议。     

Perceived severity of school bullying in elementary schools based on participants’ roles

The purpose of this study was to examine the perceived severity of school bullying among participants with different roles (victims, bullies, bullies/victims and non-involved individuals) and to determine whether interactions between type of bullying and participant roles exist. Two Olweus-like global items and a revised School Bullying Severity Scale for elementary students were used in this study. A total of 1816 valid surveys completed by students in grades 5 and 6 (mean age = 11.5, SD = .84) were collected. Data were analysed using a mixed-model two-way ANOVA. The results revealed a significant main effect of type of bullying. Physical and verbal bullying were perceived as more severe than relational and cyberbullying. A significant two-way interaction between bullying category and participant role was also identified. Bullies did not perceive the four types of victimisation behaviours differently, whereas victims and bullies/victims both rated physical victimisation as most severe and cyber-victimisation as least severe. However, effect sizes were small. Implications for bullying prevention and intervention are discussed.
