农村住宅绿色节能改造中农民满意度评价体系的构建

针对目前新农村住宅建设过程中多以住宅是否节能环保等因素来衡量其是否为绿色住宅的现状,提出人们应更多地从农民视角来建设农村住宅,并以农民满意度作为一个重要的评价指标来衡量农村住宅绿色节能改建是否合格的观点.选取16个影响农村住宅绿色改造农民满意度指标的因素,对陕西关中地区不同情况的110户农民进行了问卷调查,得到各评价指标的重要性得分.在构建农民满意度评价体系的过程中,运用因子分析法,对相关影响因素进行分类,并结合AHP的主观分析以及因子分析法的客观分析来确定各因素在每类中的权重,综合后得到最终的评价模型.

农村中介组织网络的构建策略及运行机制研究

在对农村中介组织网络构建的维度和影响因素进行界定和假设的基础上,提出了农村中介组织网络构建的策略模型.其中组织者和被组织者策略选择的首要因素是经济因素,市场买卖方和竞争者们很少考虑经济因素以外的其他因素,基层政府主要考虑政治因素.运用博弈论分析了农村中介组织网络构建策略的运行机制,发现只有有创新能力且有高可信程度的乡村成员才能在不同的博弈格局中胜出,成为农村中介组织网络构建的真正组织者.

电厂运行中汽轮机油起泡原因分析及应对措施

介绍了电厂运行中汽轮机油泡沫特性及评定泡沫特性的倾向性、稳定性指标,分析了汽轮机油的化学组分、运行中进入油系统的水汽及金属等外界杂质、运行油压及流动速度、储油箱结构及循环倍率等因素对运行中油产生泡沫的影响,提出影响汽轮机油泡沫产生的内在因素为油品的化学组分,采用适当加入与运行油具有良好相容性的消泡剂等措施在一定程度上可以降低运行中油起泡程度。     

农村住宅节能改造浅析

随着党中央对社会主义新农村建设的重视,以改善农村居住环境为起点的农村既有建筑节能改造日趋增多.本文以抚宁县石门村既有住宅节能改造项目为例子,针对农村住宅能耗特点,从建筑围护结构及可再生能源利用方面提出节能改造措施,以改善农村住宅的室内热环境,提高居民的热舒适性,达到农村住宅节能的目的.     

论从实践理解世界的物质性和自然世界的先在性

马克思主义唯物论是一种物本主义形态的唯物论,还是一种超越物本主义形态、从实践理解世界的本质相关问题的实践的唯物主义的唯物论?这是一个我们必须搞清楚的有关马克思主义唯物论的本质规定性和精神实质的重大问题.在考察物本主义的唯物论及其思维方式的局限性的基础上,揭示了马克思主义唯物论是现代的、实践的唯物主义,并重点研讨了马克思主义唯物论关于从实践理解世界的物质性和自然世界的先在性的原理,以期为马克思主义唯物论进一步阐明人类世界的实践性原理奠定基础.     

Effect of cyproheptadine on the ultrastructure of the neurons of the arcuate nucleus in the hypothalamus of the rat

The data are presented on changes in the rat arcuate nuclear neuron ultrastructure after using cyproheptadine (peritol, Egyt Pharmaceutical Works, Hungary) in a water suspension at a dose of 20 mg/kg once daily during 7 successive days and twice a day within 10 days. It was shown that cyproheptadine decreases the functional activity of the arcuate nuclear neurons, depending on the total amount of the drug used. Cyproheptadine-induced inhibition of the forming neurohormone release from neurons is likely to be one of the mechanisms of its therapeutic effect in Itsenko-Cushing's disease.     

Characteristics of the sympathetic innervation of the nictitating membrane and of the vasculature of the nose and tongue of the cat

Vasomotor responses from the nasal mucosa and tongue, and contractions of the nictitating membrane, were recorded on stimulation of the cervical sympathetic or internal carotid nerves. Preganglionic sympathetic nerve fibres which elicited a membrane response possessed a lower threshold than those which evoked nasal vasoconstriction, while the latter displayed a lower threshold than fibres which evoked tongue vasoconstriction. The sympathetic vasodilator fibres to the tongue whose activity was revealed after alpha-receptor blockade, had a similar threshold to the vasoconstrictor fibres. Membrane contraction, nasal vasoconstriction and occasionally tongue vasoconstriction could be evoked by stimulating the internal carotid nerve. The postganglionic fibres innervating the nasal mucosa had a similar threshold to those of the nictitating membrane, which may indicate that there are small myelinated fibres innervating the mucosa. The preganglionic compound nerve action potential had four major components, S1-S4. S1, S2 and usually S3 fibres were associated with membrane contraction; S2, S3 and sometimes S1 fibres were associated with nasal vasoconstriction; and S3, usually S2 and occasionally S1 fibres were associated with vasoconstriction in the tongue. It is concluded that each of these three groups of nerve fibres, but not S4 fibres, may include fibres associated functionally with the three effectors. There was a considerable difference between the relative amplitude of the responses of the three effectors elicited by stimulation of the cervical sympathetic nerve at frequencies between 0.2 and 2 Hz. Vasoconstrictor responses were relatively larger than membrane contractions suggesting differences in the mechanisms of neurotransmission at the neuroeffector junctions.
