CDM and international technology transfer: empirical evidence on wind power

This article examines the effect of the Kyoto Protocol's Clean Development Mechanism (CDM) on the international transfer of wind power technologies. The analysis is conducted using patent data from over 100 countries during the period 1988–2008. It is found that transfers from Annex I countries to non-Annex I countries are significantly affected by the contemporaneous establishment of projects under the CDM. However, when taking into account the cumulative effect of CDM projects, the effect is negative. Finally, the effect of domestic absorptive capacity in the host country is positive and significant. Because involvement with the CDM may increase the latter, this is an important area for further research.     

Deep seated magmas and their mantle roots: Introduction

<正>In the last decade there has been a considerable effort to better understand the joint evolution of mafic and ultramafic magmatic systems and their deep mantle roots,through integrated petrological and thermo-barometric studies.Magma generation is regarded as the result of complex processes including melting,creation of channels for melt transfer,and interaction with the wall-rocks.Complexities in magmatic systems involve metasomatism and the creation of metasomatic fronts,branching and splitting of magma volumes during their evolution,and vat-     

新疆伊犁吐拉苏地区的线性构造及控矿特征

采用多种数值图像进行线性构造解译，其中DEM和NOAA主要用于区域尺度，TM用于勘探区尺度，地面磁法数据用于靶区范围的解译分析。研究认为该区线性构造与金矿床的空间分布关系密切，表现为：（1）区域尺度的一级控矿构造为NEE、NE和NW向构造的交汇部位；吐拉苏地区的一级控矿构造为WNW和NNW及NE方向构造的交汇部位；（2）吐拉苏地区的次级控矿构造为NNE和环形构造的交汇部位；（3）靶区的一级控矿构造为NE、SN和环形构造。线性构造异常分析结果显示，当线性构造的优益度大于40时，有较大的成矿可能性。
