Microscopic Pore characteristics and methane sorption capacity of the lower cambrian shales in yangtze platform北大核心CSCD

The lower Cambrian develops a set of organic-rich black shales in Yangtze Platform and is regarded as one of the key layers of shale gas exploration. The microscope pore structure characteristics and methane sorption capacity were investigated using scanning electron microscope, nitrogen adsorption and methane sorption experiments, and then their controlling factors combining with organic matter, mineral compositions were discussed for Niutitang shales in Zunyi area, Mufushan shales in Nanjing area and Huangboling shales in Chizhou area. The results show as below; ( I ) The pores in lower Cambrian shales are mainly dominated by organic pores, interlayer pores in clay minerals and micro-fractures, as well as containing some intergranular pores between brittle mineral grains, honeycomb poies formed by pyrite crystals falling out, and dissolution molds in fossils; ( 2) DKT pore size distributions show the pores is mainly concentrated in the range of less than 4 nm in lower Cambrian shales and kerogens, while a certain amount of pores are above 4 nm are also existed in lower Cambrian shales, which may be contributed by smectite; ( 3)The specific surface area, pore volume and Langmuir methane sorption capacity of the lower Cambrian shales are ranging from 5.58 to 31. 96 inVg, 0.026 to 0.088 mL/g and 1.36 to 5. 3 mL/g, respectively, which are mainly controlled by TOC and smectite contents, but the effect of TOC and smectite on physical properties are quite different for the lower Cambrian shales in different regions; ( 4)The specific surface area of two Niutitang kerogens are 7. 08 and 7. 92 times than that of the shales and methane sorp-Tion capacity of kerogens arc 5.81 and 7.09 times than that of the shales, suggesting that kerogen is a main carrier of methane gas occurrence in.     

Invisible homelessness: anonymity,exposure, and the right to the city

The city of Denver, Colorado recently outlawed camping in all open space. Part of a broad effort to accelerate the profit potential of prime urban land through real estate speculation and commerce, the camping ban has dislocated homeless people from the city’s marginal spaces. Based on ethnographic fieldwork and archival research in Denver, this article develops a tripartite approach to public space—prime, everyday, and marginal—to analyze challenging ways in which people who are homeless in Denver must now manage their exposure to others in everyday public spaces. In addition to eliminating places of hard-won safety and security, this singular new code disrupts hygiene, mobility, and sociability routines, thus throwing already precarious lives into further disarray by rendering housing status visible. To demonstrate how everyday social justice springs from interaction between different people co-present in public space, we foreground the voices of Denver’s homeless people, those most impacted by quality of life laws. Evicting individuals from marginal spaces and rendering them visibly homeless in everyday and prime spaces, the ban deprives them of a fundamental right to the city: anonymity.

水电全生命周期三维可视化数字管理平台研究

水电是清洁可再生能源,在我国能源结构中占有重要的地位.为更好地发挥梯级水电开发的社会经济效益,流域水电开发企业需要融合应用信息技术,实现梯级水电站全生命周期数字化管理.本文从流域水电全生命周期管理需求和流域水电企业信息化建设现状分析出发,提出了流域水电全生命周期三维可视化数字管理平台建设思路:通过企业数据中心建设集成整合已有信息系统采集管理的梯级水电工程相关阶段的信息资源,消除信息孤岛;通过三维可视化平台建设增强信息的直观表达,也便于分析和展现数据间的关联关系.这一思路已成功指导雅砻江流域数字化平台建设,可为相关流域水电数字化平台建设提供参考.
