Monitoring of the microbial community composition in saline aquifers during CO2 storage by fluorescence in situ hybridisation

This study reveals the first analyses of the composition and activity of the microbial community of a saline CO₂ storage aquifer. Microbial monitoring during CO₂ injection has been reported. By using fluorescence in situ hybridisation (FISH), we have shown that the microbial community was strongly influenced by the CO₂ injection. Before CO₂ arrival, up to 6 × 10⁶ cells ml⁻¹ were detected by DAPI staining at a depth of 647 m below the surface. The microbial community was dominated by the domain Bacteria that represented approximately 60% to 90% of the total cell number, with Proteobacteria and Firmicutes as the most abundant phyla comprising up to 47% and 45% of the entire population, respectively. Both the total cell counts as well as the counts of the specific physiological groups revealed quantitative and qualitative changes after CO₂ arrival. Our study revealed temporal outcompetition of sulphate-reducing bacteria by methanogenic archaea. In addition, an enhanced activity of the microbial population after five months CO₂ storage indicated that the bacterial community was able to adapt to the extreme conditions of the deep biosphere and to the extreme changes of these atypical conditions.     

From mute to reflective: changing governmentality in St Petersburg and the priorities of Russian environmental planning

This paper analyses, by using a constructivist methodology, how sustainability is perceived by Russian urban and regional planners and how environmental planning is understood on a discursive level. The planning discourse, which was reconstructed primarily with the help of 14 thematic interviews undertaken in St Petersburg, is positioned on the axes of the triangle of planning contradictions. The analysis shows that the promoted planning paradigm – the interpretations about the priorities of environmental planning – stem from the expert-centred approach of the Soviet era, and poorly suits the changing governmentality of St Petersburg. Due to regime changes, a significant step from a mute to a reflective governmentality was taken in St Petersburg, but the professional planning discourse is in conflict with this context reality and prohibits a more sustainable planning standpoint from developing.     

浅谈3000t/d水泥生产线窑尾收尘系统改造

介绍了南阳航天水泥厂3000t/d水泥生产线窑尾收尘系统的改造背景、技术方案、施工方案和工程造价。改造采用了在原窑尾反吹风高温玻纤袋收尘器旁并联一台同类型单排袋式收尘器的方案,以增大窑尾袋收尘器过滤面积和降低过滤风速。该窑尾收尘系统的改造取得了明显的成效。     

河南省水泥生产过程中CO2排放量估算

水泥是重要的建筑材料,水泥工业的快速发展有力地支撑了我国经济的高速增长。但水泥生产过程中石灰石分解产生的CO2已成为重要的CO2排放源。根据2006年IPCC提供的水泥生产过程碳排放估算方法,采用全国吨水泥熟料比推算河南水泥熟料产量,对1990--2010年河南水泥生产过程CO2的排放量进行了估算,其结果可为河南省节能减排政策的制定提供科学依据。     

新疆艾比湖流域平原区景观土壤属性特征研究

以新疆艾比湖流域平原区为对象,在对研究区进行景观生态分类及野外调查验证的基础上,利用＂3S＂技术将1∶100×104的新疆土壤类型图与研究区景观类型图叠加,从土壤属性层次上对研究区各类景观的生态土壤类型进行确认,并分析其在研究区内分布的特征。结果表明：研究区主要土壤类型为26类,以石膏灰棕漠土所占比例最大,占研究区总面积的19.03%,棕钙土、荒漠风沙土、草甸盐土、盐化草甸土、和灌耕灰漠土等面积也较大。     

E‐waste in the world today: An overview of problems and a proposal for improvement in Brazil

Environmental issues have been at the center of society's concerns for a long time. Recently, this kind of concern is growing even more due to the damage caused to the environment by electrical and electronic product waste. Based on this same concern, this work aimed to analyze, through a literature review, the production and treatment of electronic waste in today's world, with an emphasis on Brazil and China. The articles reviewed point to an increase in the production of this type of waste, in both Brazil and China, and reveal that the current processes of treatment of electronic waste mostly aim to obtain profit through the recovery of precious metals such as copper. This paper concluded that although Brazil is one of the major producers of e‐waste, more than 90% of its e‐waste has not had a proper final destination. This deficiency in e‐waste treatment in Brazil is mainly due to financial factors and the lack of a robust educational policy focused on the environment. Thus, this work suggests the implementation of an effective educational policy aimed at environmental conservation, as well as investments in research on recycling methods in Brazil, especially on the use of e‐waste as an aggregate in the manufacture of concrete.

EXCEL数据处理软件在环境试验设备温度校准中的应用

人工模拟环境试验中气候环境试验的条件是否真实,主要取决于环境试验设备技术性能指标,主要包括温度偏差、温度均匀度、温度波动度.由于测试点较多,在数据处理及结果不确定度评定上工作量较大,因此使用EXCEL数据处理软件进行计算,一方面保证了数据准确可靠,另一方面提高了工作效率.

高校会计制度与公共财政体制改革衔接性研究

2009年,财政部拟定了新《高等学校会计制励（征求意见稿）,要求核算能提供预算管理需要的预算收支信息,增加了与公共财政改革相关的会计核算内容,但高校会计制度（征求意见稿）与公共财政体制依然存在着衔接不当问题。从公共财政体制改革对高校会计的影响出发,解读了高校会计制度（征求意见稿）与财政改革的衔接性,分析了高校会计实务中存在的与公共财政改革不协调的问题,并提出了相应的解决措施。
