简介：为了在无线传感器网络(WSN)完成安全通讯，在有有限计算能力的传感器节点随机在敌对领土上被散布的地方，各种各样的关键分发前策划(KPS)被建议了。在这份报纸，新KPS在有限的地上基于symplectic几何学被建议。在一个symplectic空格的固定维的subspace代表一个节点，所有1-dimensionalsubspaces表示钥匙和每个节点分享了钥匙。但是这天真的印射不保证一个好网络得到跳回。因此，它被建议二个节点不得不计算一把pairwise钥匙的提高的KPS，仅当他们分享至少q普通钥匙。这条途径对节点俘获攻击提高跳回。与解决方案的存在相比，结果证明那条新途径更加提高网络可伸缩性，并且完成好连接和好全面性能。

简介：植物有多样的策略应付磷(P)缺乏。更好理解玉米怎么对P缺乏作出回应，有二P的一个地实验铺平，0和100kgP2O5ha1(P0和P100，分别地)，作为长期的P化肥地试用的部分被执行。植物和土壤分析证明那P缺乏的玉米减少了它的生长率，增加了P使用效率，并且形成了有在连接和silking的不到0.6公里上演的直径的更多的薄根，与与P100对待的植物相比。进一步，在每收获在在rhizospheric和体积土壤之间的主要无机的P部分(Ca2-P，Ca8-P，高山，Fe-P，堵塞P和Ca10-P)没有差别，甚至当土壤Olsen-P仅仅是1.38mgkg1时。这些结果建议那玉米由由在低碳的词法改变花费了的有利的根为生长和增加的P获得能力减少内部P需求对P缺乏作出回应。

简介：这研究的目的是估计在印度的东南的海岸在Tirumalairajan河河口在10表面沉积选择重金属(Fe，Mn，Cu，Zn，Pb，Cr，公司和Ni)划分的化学药品。一种五步的顺序的抽取技术被用来估计重金属的环境地位。大多数金属被认为由于在重金属的剩余部分的高可获得性不动。Tirumalairajan河河口的沉积没被重金属弄脏，并且他们没提出任何高生态的风险。重金属的季节的变化比在季风季节在夏天是稍微更高的。因素分析也被执行与沙，淤泥，泥土，有机物，pH，咸度和另外的金属在不同部分理解金属的协会。在Q模式和R模式簇分析之间的关系为在两个季节识别污染层次是有用的。重金属的丰富与地球表面形成学、人为的来源一起是相关的，这被证明。在沉积的全部的金属集中的信息不为在环境估计金属行为是足够的，但是顺序的抽取技术在估计污染沉积的环境影响是更有效的。

简介：城市的人口在白天期间并且在夜里和他们的空间分发是为计划城市的基础结构，公共服务和灾难地势的重要的底。当当前的人口统计不能在夜里在白天期间把城市的人口与那区分开来，这个领域里的存在研究是相当有限的。这篇论文试着由建立一个关系模型让人口，陆地使用和时间(白天或夜里)的三个部件探索人口的不同类型的时间、空间的特征在这个方面推进研究，它被瞄准在白天期间并且在夜里估计城市的人口并且在格子规模分析他们的空间特征。而且，实验案例研究在中国北京在Haidian区域被执行了测试模型。结果如下：(1)城市的人口的空间结构在夜里与那在白天期间显著地不同。城市的人口的空间分发在白天期间是更广泛的，更多聚结那那在夜里。(2)在人口之间的空间联合关系的几种类型在在夜里的白天和那期间被识别了，例如三明治模式，对称模式，集中模式和单个模式，等等(3)白天和夜间人口的空间分发也在中国的发展期间反映某些因素例如旧居住区域，新工业区域的构造，和城市、农村的区域之间的差别的分发，它能提供参考
