[橡胶和塑料制品业,电力、热力、燃气及水生产和供应业,汽车制造业,黑色金属冶炼和压延加工业,有色金属冶炼和压延加工业] [2014-08-07]
前4个月,物流与生产资料市场运行基本平稳、结构优化。一方面,市场规模增速稳中小幅回落,但保持较快增长;另一方面,在增速回落的同时,市场结构向好转变、流通方式加快转型。当前经济运行中值得关注的问题,主要表现在两个方面:一是宏观层面上,投资需求偏弱;二是微观层面上,企业资金紧张、应收账款大幅上升。此外,企业经营面临的政策环境有待进一步优化。从后期走势看, PMI 指数连续两个月小幅回升,市场需求有所改善,生产资料市场价格呈现出趋稳走势,显示出宏观经济运行积极向好发展具有一定的基础。在此背景下, 行业保持平稳运行仍具备有利条件。

14766.绿色星球架构-一种自我维持的分布式可再生能源生态系统的方法论
[电力、热力、燃气及水生产和供应业] [2014-08-06]
Our planet has been endowed with a host of natural mechanisms to keep the environment and climate in balance. Humans are now facing the need to restore this balance that has been upset in the past years because of a growing population and resource demands. To steer dependency away from freshwater crops and decrease environmental damage from humanity s fuel and energy demands, it is necessary to take advantage of the natural adaptive biomass resources that are already in place. Using methods of Green Planet Architecture, based on compilations of current research and procedures, could lead to new forms of energy and fueling as well as new sources for food and feed. Green Planet Architecture involves climatic adaptive biomass; geospatial intelligence; agri- and aqua-culture life cycles; and soil, wetland, and shoreline restoration. Plants such as Salicornia, seashore mallow, castor, mangroves, and perhaps Moringa can be modified (natural, model-assisted, or genetically modified) to thrive in salt-water and brackish water or otherwise not arable conditions, making them potentially new crops that will not displace traditional farming. These fueling sources also have potential to be used in other rapid-growth industries, such as the aviation industry, that have incentive to move towards more sustainable fuel supplies. This paper highlights an example of how synergistic development of biomass resources and geospatial intelligence high-performance computing capabilities can be focused to resolve potential drought-famine problems. These techniques, provide a basis for future e-science-based discovery (and access) through technology that can be expanded to support global societal applications.

14767.氨脱氮工艺的污水处理厂基于模型的控制
[电力、热力、燃气及水生产和供应业] [2014-08-06]
Ammonia nitrogen removal is one of the most important processes in wastewater treatment plants (WWTPs). It is performed by microorganisms (referred to as biomass) in aerobic reactors in an activated sludge process. For normal operation a sufficiently high oxygen concentration has to be maintained at all times in the reactor by appropriate aeration. Aeration should be such that the effluent ammonia concentration (daily averaged or peak values) never exceeds the limit prescribed by legislation irrespective of the variable influent, changing weather and plant condition. At the same time, the lowest possible air consumption must be achieved. The reasons are purely economic. According to a study, air consumption is responsible for more than 50of the total electrical energy consumed by the plant. For example, aeration costs at a WWTP designed for around 100,000 people can be more than € 150,000 per year.

14768.大气化学和气候模型相互对比项目(ACCMIP)中的氮硫沉积模型平均:评价历史和预期变化
[电力、热力、燃气及水生产和供应业] [2014-08-06]
We present multi-model global datasets of nitrogen and sulfate deposition covering time periods from 1850 to 2100, calculated within the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP). The computed deposition fluxes are compared to surface wet deposition and ice-core measurements. We use a new dataset of wet deposition for 2000-2002 based on critical assessment of the quality of existing regional network data. We show that for present-day (year 2000 ACCMIP time-slice), the ACCMIP results perform similarly to previously published multi-model assessments. For this time slice, we find a multi-model mean deposition of 50 Tg(N) yr1 from nitrogen oxide emissions, 60 Tg(N) yr1 from ammonia emissions, and 83 Tg(S) yr1 from sulfur emissions. The analysis of changes between 1980 and 2000 indicates significant differences between model and measurements over the United States but less so over Europe. This difference points towards misrepresentation of 1980 NH3 emissions over North America. Based on ice-core records, the 1850 deposition fluxes agree well with Greenland ice cores but the change between 1850 and 2000 seems to be overestimated in the Northern Hemisphere for both nitrogen and sulfur species. Using the Representative Concentration Pathways to define the projected climate and atmospheric chemistry related emissions and concentrations, we find large regional nitrogen deposition increases in 2100 in Latin America, Africa and parts of Asia under some of the scenarios considered. Increases in South Asia are especially large, and are seen in all scenarios, with 2100 values more than double 2000 in some scenarios and reaching 1300 mg(N) m2 yr1 averaged over regional to continental scale regions in RCP 2.6 and 8.5, 3050 larger than the values in any region currently (2000). The new ACCMIP deposition dataset provides novel, consistent and evaluated global gridded deposition fields for use in a wide range of climate and ecological studies.

14769.VOC的内生真菌是由木质纤维素生物质原料的性质改变
[电力、热力、燃气及水生产和供应业] [2014-08-06]
Biofuel production from cellulosic feedstocks is a grand challenge that is being pursued on a number of fronts. One promising area is engineering of organisms that can directly convert biomass into more technologically useful forms. The technologies for next generation biofuels must not only design efficient processes to convert lignocellulosic biomass to liquid fuels but must also ensure that produced fuels are compatible with current and future engines. Endophytic fungi have been shown to produce a range of moderate-molecular weight hydrocarbons (volatile organic compounds-VOC) directly from cellulosic biomass without any pretreatment. These organisms have the capacity to alter their VOC profile as a function of carbon source. We cultured a number of these fungi on potential biofuel biomass (corn stove, eucalyptus and switchgrass) as the sole carbon source and their growth rates were compared to potato dextrose agar. We then performed a VOC profile of the biomass-supported fungal cultures. Our findings are an important first step in developing industrial hosts (microbes or fungi) with both biomass deconstruction and fuel synthesis pathways. Follow-up genomic and proteomics are needed to link genomics based information to function which will allow us to identify and understand response thresholds and determine how populations can be controlled for more sustainable out comes.

14770.木质生物反馈堆场业务发展指南。开发一个木质生物质集货场的资源和业务指南
[电力、热力、燃气及水生产和供应业] [2014-08-06]
A woody biomass 'feedstock yard'. is a collection point or location for collecting and concentrating biomass from various sources. Biomass is collected, sorted, consolidated, processed and distributed to a variety of markets and uses. It provides an alternative in the biomass supply chain that could have benefits over traditional woods-to-processor delivery scenarios. This guide has been designed for those interested in developing a business to supply woody biomass for forest products, wood energy and other uses. The guide provides information about the development, operation and management of a woody biomass feedstock yard. For example, a woody biomass feedstock yard could be developed to help solve a disposal problem, recover and utilize a natural resource, contribute to the local economy and the environment, or as a way to be a better steward for taxpayers. A woody biomass feedstock yard could help guide a 'woods wise' person to own and operate a small business enterprise. Woody biomass is an abundant and renewable feedstock for energy and other uses and may present an opportunity for those willing to make investments. This guide provides information and guidance on the establishment of a business and ways to improve the operation of an existing business.
