one of the most promising tools for the control of fungal plant diseases is spray-induced gene silencing(SIGS).In SIGS,small interfering RNA(siRNA)or double-stranded RNA(dsRNA)targeting essential or virulence-related pathogen genes are exogenously applied to plants and postharvest products to trigger RNA interference(RNAi)of the targeted genes,inhibiting fungal growth and ***,SIGS is limited by the unstable nature of RNA under environmental *** use of layered double hydroxide or clay particles as carriers to deliver biologically active dsRNA,a formulation termed BioClay^(TM),can enhance RNA durability on plants,prolonging its activity against ***,we demonstrate that dsRNA delivered as BioClay can prolong protection against Botrytis cinerea,a major plant fungal pathogen,on tomato leaves and fruit and on mature chickpea *** increased the protection window from 1 to 3 weeks on tomato leaves and from 5 to 10 days on tomato fruits,when compared with naked *** flowering chickpea plants,BioClay provided prolonged protection for up to 4 weeks,covering the critical period of poding,whereas naked dsRNA provided limited *** research represents a major step forward for the adoption of SIGS as an eco-friendly alternative to traditional fungicides.

Neutral aluminum clusters Aln (n up to 30) have been generated using laser vaporization and pulsed molecular beam techniques. The neutral clusters are photoionized by a 193 nm excimer laser and detected by a Wiley-McLaren time of flight (ToF) mass spectrometer. 2p, 1g and 3s electronic shell closings are revealed at Al13,Al19 and Al23, respectively. Geometric effects also contribute to stability the intensity discontinuities, at least within the present investigated cluster size range.

作者： C.Selvaraj o.S.Babu G.Murugusundaramoorthy Department of Mathematics Presidency College (Autonomous) Department of Mathematics Dr. Ambedkar Govt. Arts College School of Advanced Sciences VIT University

In this paper, we introduce and investigate a new subclass of the function class ∑. of bi-univalent functions of the Mocanu-convex type defined in the open unit disk, satisfy Ma and Minda subordination conditions. Furthermore, we find estimates on the Taylor-Maclaurin coefficients ｜a2｜ and ｜a3｜ for functions in the new subclass introduced here. Further Application of Hohlov operator to this class is obtained. Several （known or new） consequences of the results are also pointed out.

Corrosion Behavior of Alumina Reinforced Aluminium (6063) Metal Matrix Composites

引用

Journal of Minerals and Materials Characterization and Engineering 2011年第12期10卷 1153-1165页

作者： K. K. Alaneme M. o. Bodunrin Department of Metallurgical and Materials Engineering Federal University of TechnologyAkure Nigeria

The influence of alumina volume percent and solution heat-treatment on the corrosion behaviour of Al (6063) composites and its monolithic alloy in salt water, basic and acidic environments is investigated. Al (6063) – Al2o3 particulate composites containing 6, 9, 15, and 18 volume percent alumina were produced by adopting two step stir casting. Mass loss and corrosion rate measurements were utilized as criteria for evaluating the corrosion behaviour of the composites. It is observed that Al (6063) – Al2o3 composites exhibited excellent corrosion resistance in NaCl medium than in the NaoH and H2So4 media. The unreinforced alloy exhibited slightly superior corrosion resistance than the composites in NaCl and NaoH media but the composites had better corrosion resistance in H2So4 medium. Furthermore, solution heat-treatment resulted in improved corrosion resistance for both the composites and the unreinforced alloy while the effect of volume percent alumina on corrosion resistance did not follow a consistent trend.
