The primary objective of this research is to delineate potential groundwater recharge zones in the Kadaladi taluk of Ramanathapuram,Tamil Nadu,India,using a combination of remote sensing and Geographic Information Systems(GIS)with the Analytical Hierarchical Process(AHP).Various factors such as geology,geomorphology,soil,drainage,density,lineament density,slope,rainfall were analyzed at a specific *** layers were evaluated for quality and relevance using Saaty's scale,and then inte-grated using the weighted linear combination *** weights assigned to each layer and features were standardized using AHP and the Eigen vector technique,resulting in the final groundwater potential zone *** AHP method was used to normalize the scores following the assignment of weights to each criterion or factor based on Saaty's 9-point ***-wise matrix analysis was utilized to calculate the geometric mean and normalized weight for various *** groundwater recharge potential zone map was created by mathematically overlaying the normalized weighted *** layers indicating major elements influencing groundwater occurrence and recharge were derived from satellite images.2 Results indicate that approximately 21.8 km of the total area exhibits high potential for groundwater *** recharge is viable in areas with moderate slopes,particularly in the central and southeastern regions.

In this paper, a nonlinear model is presented to describe wave transformation in shallow water with the zero- vorticity equation of wave- number vector and energy conservation equation. The nonlinear effect due to an empirical dispersion relation (by Hedges) is compared with that of Dalrymple's dispersion relation. The model is tested against the laboratory measurements for the case of a submerged elliptical shoal on a slope beach, where both refraction and diffraction are significant. The computation results, compared with those obtained through linear dispersion relation, show that the nonlinear effect of wave transformation in shallow water is important. And the empirical dispersion relation is suitable for researching the nonlinearity of wave in shallow water.

INCREASING evidence has demonstrated that the locally controlled proteolytic activity generatedby coordinated expression of tPA and PAI-1 in different tissues may play an important role inmany reproductive events. These are largely related to fibrinolytic activity. They include folli-cle rupture, luteolysis, spermatogenesis and trophoblast implantation. Parturition, whichis a complex process, may also be associated with tissue destruction. Detachment of placentaldecidua and partial breakdown of fetal membranes are possible examples. It has been

The gas chromatographic separations of aromatic compounds using special mixed stationary phases consisting of pp-beta-CD+AgNO3, pp-beta-CD+TINO3, pp-beta-CD+di-n-butly phthalate, pp-beta-CD+BPBHpB liquid crystalline, and bentone-34+AgNO3 were investigated. Besides pp-beta-CD+di-n-butyl phthalate, most of the separations deviated from the additivity and a synergistic effect was observed. The separation effects depend on the temperature and how mixing is accomplished.

Tailoring non-metallic inclusions in accordance to the desired effect on steel properties has gained widespread acceptance in the last decades and has become known as “inclusion engineering”. Effective inclusion engineering involves three steps：（a） a good knowledge of how inclusions influence properties, （b） understanding what is the effect of each type of inclusions on these properties and thus which is the most desirable inclusion in a given product and （c） adjusting the processing parameters to obtain these inclusions. A significant portion of the process adjustment is done during steel refining, where the steel can be tailored so that the desired chemical composition of the non-metallic inclusions that will precipi- tate can be altered. Understanding the relations between steel chemistry, processing variables and inclusion chemical composition requires significant understanding of the thermodynamics of the systems involved. These complex equilibrium calculations are best done using computational thermodynamics. In this work some of the basic techniques used to control inclusion composition are reviewed and the thermodynamic information required to perform this task is presented. Several examples of the application of computational thermodynamics to inclusion engineering of different steels grades are presented and compared with experimental results, whenever possible. The potential and limitations of the method are highlighted, in special those related to thermodynamic data and databases.

基因治疗是未来临床医学最具潜力的治疗方式,目前阻碍临床基因治疗发展的主要因素是缺乏安全和高效的基因载体,因此研究理想的非病毒转基因载体具有重要的意义.构建了由质粒DNA(D)-抗DNA抗体(A)-阳离子脂质体(C)组成的三元复合纳米基因载体(DAC),研究表明,三组分在磷酸缓冲液中可通过分子组装形成复合纳米胶束,DAC在细胞培养中表现出显著高效的基因表达,DAC在血管平滑肌细胞中的基因转染效率比不含抗DNA抗体的二元组合(DC)高4倍,比不含阳离子脂质体的二元组合(DA)约高11倍.激光共聚焦荧光显微观察证明,DAC细胞摄取量和DNA进入细胞核的量均明显高于对照组,而DC二元组合(不含抗DNA抗体)的DNA很少进入细胞核,细胞在DAC存在下生长正常.未发现细胞毒性.研究结果提示,DAC的作用机理主要是三元复合胶束中DNA的装载量比二元载体大得多,抗DNA抗体与阳离子脂质体的协同作用明显有利于DNA被细胞摄取和胞吞,从而提高了基因的转染和表达.

野生反刍动物一天中大部分时间用于摄食与反刍。为了适应采食生态环境与食物类型，野生反刍动物的行为表现出高度可塑性。反刍动物的采食活动节律受到食物摄入速率和消化能力的影响．摄入速率又受食物丰度、分布和动物的采食经验的影响。动物的消化能力则与食物质量、消化性能、排空速率以及消化道的充盈程度有关。一年四季中，美洲马鹿（Ｃｅｒｖｕｓｅｌａｐｈｕｓｎｅｌｓｏｎｉ）的采食频次和持续时间变化很大。在加拿大阿尔伯达中部的针阔混交林中，我们研究了食物质量和丰度、气温对美洲马鹿的昼夜采食节律的影响。食物丰度影响了摄食速率。食物质量决定了消化道内容物的排空速率和消化速率。春天，当气温适中，可消化性高的青草茂盛时，美洲马鹿具有多相采食活动节律（较均匀分布的多个采食周期）。此时，瘤胃的排空可能引发采食。夏天，午间高温抑制了采食活动。此时，美洲马鹿的采食活动呈双峰型。冬天，尽管美洲马鹿的采食量下降，由于食物的纤维素含量高，美洲马鹿仍花费较多的时间反刍咀嚼，但这些活动多集中于气温较高的午间。极度低温会抑制美洲马鹿的摄食。而当气温回升后，美洲马鹿会补偿性地延长采食时间。美洲马鹿的昼夜采食节律季节性变化是其适应北方寒带气候和觅食环境的生态行为?
