Their sensitivity can be enhanced greatly if the grating period, fiber dimensions and surrounding refractive index are optimized in a way to operate at a point called turn around point on phase matching curves of these gratings. Turn around point LPFGs are well known for their ultrahigh sensitivity to external parameters. Potential of operating LPFG at or near turn around point has been investigated by many researchers in various applications including physical parameter sensing, adulteration detection, radiation dose, etc. Since TAP LPFGs are in investigation phase therefore a lot of rigorous & efficient work in finding techniques for optimizing their potential as sensor in chemical, biochemical, structural health monitoring is still to be carried out. A brief review of work carried out in this domain till now is presented here and key findings from literature review are highlighted.展开更多

It is also difficult to notice the correlations among the different times of the history without falling in anachronistic mistakes. In fact, it is well-known that a historian must be wise and rational when he finds those correlations, because every society has its own characteristics, structures, and mentality. This brief essay focuses on the social structures in a north eastern italic region, which is called Friuli, between the 12th and 16th centuries. In the above mentioned centuries, it is possible to notice an evolution from a feudal ecclesiastical principality, ruled by prince-patriarchs, ecclesiastical institutions and nobility, to a more fluid and dynamic constitution formed by new classes which rose up in times of urban and economic development. But this development struggles to delete the old system, which persisted until the end of 18th century with the arrival of Napoleon. The transition from the Patriarch's power to Venice's dominion seems to have created two main consequences: by one hand a more bureaucratic and modem structure of the State, by the other hand a consolidation of the old connections between patrons and clients, consequence of the "modem" feudal system that consolidated its roots in the Late Middle Ages centuries.展开更多

This article provides a brief overview of the most important aspects of their activities in restoring the State of Lithuania and actively joining its activities in the inter-war period. In the end of 1919, the Women's Circle to Aid the Solders was established, and Jewish women were active in its activities. The participants of the women's circles were awarded the medals of the 10th anniversary of the Lithuanian Independence for their activities. The women established and actively worked in the Lithuanian Women Committee to Protect the Homeland as a response to the call-back of the Chief Defence Committee. After the Independence fights, during the period of the democratic Lithuanian state (1920-1926), the Jewish women actively took part in the self-governing institutions. Especially active were the Jewish socialist labourists and Jewish laboursits' groups. This activity diminished during the period of the authoritarian regime (1926-1940).展开更多

The group founded a review Socialisme ou Barbarie that criticized Marxism and the Trotskyist interpretation of the status of the USSR. The rigorous description of this review reveals the mixture of strong theoretical views on bureaucratic societies and empirical investigations of reactions against those societies. The hypothesis is that this group failed to be a new political force. As a matter of fact, is it possible to depict the evolution of Socialisme ou Barbarie as an investigative journalism based on a strong political and philosophical theory?展开更多

文摘利用1982年至2003年NASAGIMMS逐月归一化植被指数(NDVI)数据集和玛曲县气温、降水资料,对玛曲县近22年来NDVI变化和气候变化特征及其相互关系进行分析,以揭示黄河上游地区植被对全球变暖的区域响应.结果表明:(1)玛曲县植被变化在不同时段表现出较大差异,NDVI年际变化略有增加.(2)夏季是NDVI增长最快的季节,春季NDVI在20世纪90年代后期到本世纪初呈下降趋势,秋、冬季NDVI呈下降趋势.(3)返青期和NDVI值在春季达到同一水平值的时间及夏季达到峰值的时间逐年提前,说明生长季提前是该地区植被对全球变暖的主要响应表现.(4)玛曲县近22年来植被的NDVI变化在中等盖度水平(0.3~0.5)呈增加趋势,高盖度水平(≥0.7)的植被呈下降趋势,而在年代间变化水平上,气温和降水对植被生长都有影响,其中气温要比降水更显著;玛曲县降水和气温在季节尺度上对NDVI的影响不明显,除夏季气温与夏季NDVI关系密切之外,其他季节的关系均不明显.(5)按植被变化特点,将NDVI变化斜率最大值0.005定义为返青期指标,发现该地区牧草返青期的变化主要受温度条件影响,随气候变暖,返青期提前,其变化规律为4~5月份平均气温每10年升高0.6℃,返青期每10年提前3 d.
