Th. effect of moisture conservation and nutrient management on growth.and yield of rabi sorgh.m was studied at th. Zonal Agricultural Research.Station, Babbur Farm, h.riyur Karnataka under rainfed conditions on medium black soil during rabi seasons of 2007-2008 and 2008-2009. Paired row planting (30-60-30 cm) and opening of furrow in wide rows at 35 Days After Sowing (DAS) proved superior over sowing across th. slope and even ridges and furrows with.tied ridging in terms of grain yield (1.10 t/h.), stover yield (1.51 t/h.) and 1000 grain weigh. (24.6 g). Similarly application of 50% recommended dose of fertilizer (RDF + Farm yard Manure (FyM) 2.5 t/h. + Microbial consortia (Trich.derma, Azospirillum and Ph.sph.te Solubilizing Bacteria (PSB) recorded significantly h.gh.r plant h.igh. (121 cm), panicle length.(8.7 cm), panicle diameter (7.4 cm), 1000 grain weigh. (24.3 g), grain yield (0.95 t/h.) and stover yield (1.42 t/h.) over oth.r treatments but on par with.th. application of 100% RDF + FyM 2.5 t/h.. Paired row planting (30-60-30 cm) and opening of furrow in wide rows at 35 DAS was also superior with.maximum output energy of 43350 MJ/h., rainwater use efficiency of 5.15 Kg/h./mm and BC ratio of 2.31. Similarly application of 50%RDF + FyM 2.5 t/h. + Microbial consortia recorded h.gh.r output energy of 39525 MJ/h. and rainwater use efficiency of 4.48 Kg/h./mm.

RNAi is th. meth.d of silencing th. expression of targeted genes. RNAi applications include gene function analysis and target validation. Designing h.gh.y efficient small interference RNA (siRNA) sequence with.maximum target specificity for mammalian RNAi is one of important topics in recent years. In th.s work, a statistical analysis of th. information for a large number (3734) of siRNA presented in th. database available on th. internet is done. Th.s is to improve th. design of efficient siRNA molecules. Th. (3734) siRNAs are classified according to th.ir efficiency to th.ee groups (h.gh.efficient, moderate efficient and low efficient). Th.rteen properties (positional and th.rmodynamics) are identified in th. h.gh.efficient group in th. primary statistical study. In th. final statistical study, th. average weigh. of each.identified property is calculated. A very good linear correlation was found between th. average percentage efficiency and th. weigh.ed score of siRNA properties. It is found th.t th. most important feature of h.gh.y efficient siRNA is th. difference in binding energy between th. 5’ end and th. 3’ end of th. anti-sense strand. Th. (RISC) activation step is a critical step in RNAi process wh.re th. efficiency of th.s process depends on th. instability of th. 5’ end of th. anti-sense strand.

Tubulobulbar Complexes (TBCs) are actin-rich.structures formed between Sertoli-cells and spermatids at th. time of sperm release. Th. main functions of th. TBCs are to remove excess spermatid cytoplasm and acrosomal contents, internalize and recycle junctional complexes by endocytosis prior to spermiation. h.wever, in addition to recycling some of th. molecules undergo lysosomal degradation. Th. molecular mach.nery involved in endocytosis at th. TBCs is not well understood. To bridge th.s gap localization of various proteins, involved at various steps of endocytosis studied in oth.r systems, was demonstrated in TBCs using testicular fragmented material or sections by immunoblotting and immunofluroscence. Th. presence of key molecules like Vamp-2, syntaxin and Lamp-2 indicates occurrence of lysosomal degradation in addition to junctional recycling at th. TBCs present at th. time of sperm release. TBCs are endocytic devices functioning to recycle junctional molecules or remove spermatid cytoplasm th.t were present between spermatids and Sertoli-cells all th.ough.th. process of spermatid maturation and in turn regulate male fertility.

Micro-scale abrasion testing is widely used to determine th. abrasion resistance of th.n film coatings; it is a simple tech.ique th.t can easily be used as part of a quality control procedure, but it h.s got th. disadvantage of not allowing an easy study of th. wear mech.nisms involved: it is difficult to estimate th. load applied on each.abrasive particles in th. contact between th. loaded ball and th. specimen. Th. possibility of using progressive loading scratch.testing, a meth.d widely used to assess th. adh.sion of th.n film coatings, to model th. abrasive wear of coatings h.s been studied in th. past; th. use of multiple scratch.tests to study th. wear mech.nisms corresponding to a single abrasion scratch.event h.s also been studied in th. case of bulk materials (ceramics and h.rd metals). Two coatings, deposited by Closed Field Unbalanced Magnetron Sputter Ion Plating (CFUBMSIP) on ASP23 powder metallurgy steel substrate are ch.sen to be representative of th. use of protective coatings in industry: titanium nitride, wh.ch.is widely used to prevent tool wear, and TCL Graph.t-iC?, wh.ch.is widely used as a wear resistant solid lubricant coating. Th. two coatings are first ch.racterised by using a standard quality control procedure: th.ir th.ckness is determined by th. cap grinding meth.d, th.ir adh.sion by progressive loading scratch. Th.n micro-scale abrasion tests performed with.a slurry at a concentration wh.ch.promotes grooving wear, and medium load multiple scratch.tests performed with.diamond indenters are completed; th. results of th.se tests are analysed and compared to determine if th.re is any correlation between th. two sets of results; th. multiple scratch.tests wear tracks are also observed to determine th. wear mech.nisms involved.

Black box functions, such.as computer experiments, often h.ve multiple optima over th. input space of th. objective function. Wh.le traditional optimization routines focus on finding a single best optimum, we sometimes want to consider th. relative merits of multiple optima. First we need a search.algorith. th.t can identify multiple local optima. Th.n we consider th.t blindly ch.osing th. global optimum may not always be best. In some cases, th. global optimum may not be robust to small deviations in th. inputs, wh.ch.could lead to output values far from th. optimum. In th.se cases, it would be better to ch.ose a sligh.ly less extreme optimum th.t allows for input deviation with.small ch.nge in th. output;such.an optimum would be considered more robust. We use a Bayesian decision th.oretic approach.to develop a utility function for selecting among multiple optima.

In th.s work th. auth.rs present a calculation process of th. blades for wind turbine with.h.rizontal axis. It is about a blade discretized by th. finite element meth.d （FEM） in order to determine th. gyroscopic effect during its rotation at a h.gh.speed. A blade must h.ve th. maximum output and resist to aerodynamic loads distributed over its length. wh.ch.are related to its geometrical ch.racteristics and th. speed of th. wind. For th.t, th. auth.rs wrote th. relations wh.m determine th.se loads according to th. flow speed of th. wind, th.n, th. auth.rs integrated th.m in th. laws of structure mech.nics to obtain th. motion equations of th. blade. Th.s process was applied to a twisted blade with.a length.of 1.9 m, built out of pressed aluminum sh.et with.a profile of th. type NACA; th.s profile gives th. best aerodynamic output. Th.s blade is an element of a th.ee-bladed propeller for wind turbine of maximum power 5 kW. Finally, we visualized its deformations and th.n th. auth.rs ch.cked its h.lding in service.

利用“固体与分子经验电子理论”的BLD方法建立了Fe-C马氏体的价电子结构。碳原子连同其第1、2、3近邻Fe原子构成的小块形成含碳价电子结构单元;相应的不含碳的小块构成不含碳价电子结构单元,两者混乱分布构成马氏体晶体。对1.7wt-％C马氏体得出:含碳结构单元内Fe_Ⅰ,Fe_Ⅱ,Fe_Ⅲ分别在甲种杂化第11,10,8各阶,碳在第6阶;不含碳结构单元内Fe在甲种杂化第8阶。含碳结构单元内n_A=0.9991,n_B=0.8479;不含碳结构单元内n_A,n_B日与α-Fe相同。不同含碳量马氏体中只是两类结构单元相对数量不同。比较两类结构单元的n_A和n_B,立即看出马氏体硬度随含碳量增加而提高,这与实验事实一致。
