Trans-ocean wireless transfer of electricity from continent to continent

The author offers collections from his previous research of the revolutionary new ideas: wireless transfer of electric energy to a long distance – from one continent to another continent through the Earth's ionosphere and the storage of the electric energy in the ionosphere. Earlier he also suggested the use of electronic tubes as the method for transportation of electricity into outer space and the 100-km electrostatic space towers for connection to the Earth's ionosphere. Earlier a connection to the Earth's ionosphere using 100-km solid or inflatable towers was suggested. however, the technology faces difficulties. In this work, connection to the Earth's ionosphere by thin plastic tubes supported in the atmosphere by electron gas and electrostatic force is researched. Building this system is cheap and easy using the current technology. The computation allows estimating the possibility of the suggested method.     

Industrial layout reconstruction,the role of local government and variation of pollution distribution in China

ABSTRACT

In recent years, high-polluting industries have been gradually shifted from the eastern developed regions to the central and western underdeveloped regions in China. Certain environmental regulations have been in place accordingly in various regions, but the pollution in the central and western regions has risen sharply. Based on the data of interprovincial panel in China from 2006 to 2015, this paper calculates high-pollution industry dynamic agglomeration index, environmental pollution agglomeration index and relative environmental regulation intensity index, and uses Generalized Method of Moments to carry out the regression analyses of the whole samples, regional heterogeneity and temporal heterogeneity. The results show that there is an inverted U-shaped relationship between relative environmental regulation and environmental pollution concentration in China. The concentration degrees of industrial wastewater pollution and industrial waste gas pollution are deepened, which are mainly caused by the transfer of highly polluting industries. However, the concentration of industrial solid waste pollution caused by the transfer is not obvious. Furthermore, the deepening of industrialization intensifies the concentration of regional environmental pollution. Environmental Kuznets Curve does exist in China, but it is not significant. The increase of labor cost and quality will reduce the concentration of environmental pollution.     

可见光促有机物诱导铁还原的多相类芬顿体系强化效能与机制

近年来,亚铁离子活化过硫酸盐的类芬顿(Fe²⁺-PMS/PS)高级氧化技术发展日趋成熟,但因Fe³⁺无法还原导致反应停止的问题仍制约其大规模应用.结果发现,当把以双酚A（BPA）为代表的某些有机物与Fe³⁺和TiO₂混合,所形成的某种络合物可以拓宽TiO₂光响应范围捕获可见光,通过TiO₂将光生电子传递给Fe³⁺进行还原,从而实现Fe³⁺/Fe²⁺的无限循环.依据上述原理,构建了可见光下BPA-TiO₂-Fe³⁺-PS复合体系来降解BPA,并对其催化性能、催化机制和影响因素进行探讨.结果表明,该体系具有突出的催化性能,60 min内BPA(50 mg·L^-1)降解率达到93.1%,矿化度达到70%.同时验证该体系可以通过双酚A自生光电子还原Fe³⁺, 60 min还原得到的Fe²⁺稳...     

模糊综合评判法在西部地区高速公路施工现场安全评判中的应用

目前随着高速公路建设的飞速发展,引发了施工现场的安全管理难度剧增,及时、正确地掌握和评判施工现场安全状况是预防和控制安全事故发生的有效途径。但公路施工领域安全评判涉及的因素很多,模糊性大、动态变化复杂是最显著的特性,因素之间互相作用使结果可变性很大,如何对受多种因素制约的事物或对象做出一个总体的评价是目前一个很重要的问题。模糊综合评判法可把定性评价转化为定量评价,能较好地解决模糊的、难以量化的问题。但由于该法使用的评语常带有模糊性,各影响因素的权重通常是专家凭经验给出,从而影响评判结果的客观性。而层次分析法适用于多方案或多目标的决策,可将定性与定量的分析相结合,可以减少评价中因主观性所带来的弊端,使评价结果更可信。本文在研究模糊综合评判法和层次分析法优缺点的基础上,将二者结合起来,建立西部地区高速公路施工现场安全状况评价的模型,利用该模型得出公路施工现场安全状况,为施工现场的安全管理和事故防治提供依据。

Designing a mixed performance measurement system for environmental supply chain management using evolutionary game theory and balanced scorecard: A case study of an auto industry supply chain

This paper proposes a mixed performance measurement system using a combination of evolutionary game theory and the balanced scorecard (BSC) in environmental supply chain management (ESCM) that measures and evaluates business operations using the four different perspectives of finance, customer, internal business process, and learning and growth. ESCM plays an important role in the supply chain which leads to the reduction, reuse and recycling of resources involved in both upstream and downstream activities. This paper presents guidance for practical managers in evaluating and measuring ESCM by developing a knowledge-based BSC and evolutionary game theory. The primary purpose of this paper is to apply the proposed method in a case study to one of Iran's biggest auto industry supply chain SAIPA Company. The results of this study indicate that the adoption of ESCM, in the absence of regulatory pressures and cost-saving measures is triggered by public pressures and its implementation is limited by organizational factors and strategic myopia.

Trade, technology, and the environment: Does access to technology promote environmental regulation?

Focusing specifically on regulation of coal-fired power plants, we examine how technological innovation by early adopters influences the timing of new environmental regulation in non-innovating countries. We build a general equilibrium model of an open economy to identify the political-economy determinants of regulation. With a newly created dataset of SO₂ and NO_x regulations for coal-fired power plants and a patent-based measure of the technology frontier, we estimate the determinants of environmental regulation diffusion. Our findings support the hypothesis that international economic integration eases access to environmentally friendly technologies and leads to earlier adoption, ceteris paribus, of regulation in non-innovating countries. However, we also find evidence that domestic trade protection promotes earlier adoption allowing shifts of regulatory costs to domestic consumers. Furthermore, international market power permits large countries to shift costs to foreign consumers. Other political economy factors, such as the quality of domestic coal, are also important determinants.
