Abrasiv. wear of a series of WC-(5%-14%, mass fraction)Co hardmetals was inv.stigated emp.oying coarse and fine SiC abrasiv. under two-body dry abrasion conditions with p.n-on-disc and edge-on-disc test arrangements. Unexp.ctedly, it is found that submicron grades demonstrate substantially higher wear rates comp.ring with the coarse grades if fine abrasiv. is utilized in p.n-on-disc tests. Such a behav.or is attributed to changes in a ratio of abrasiv. size to size of hard p.ase as finer abrasiv. is used. The edge-on-disc test demonstrates that edge wear may be described in two stages with the highest wear rates at the beginning stage. This behav.or is associated with a transition of wear mechanisms as edge is wider due to wear. Comp.red with the ultrafine grades of the same Co content, the coarse grades demonstrate higher wear rates at the beginning, but lower wear rates at the final stage. Wear rates and mechanisms observ.d at final stage correlate well to the results observ.d for p.n-on-disc tests emp.oying fine abrasiv..

p.rtial shading is a common p.enomenon in p. arrays. They drastically reduce the p.wer outp.t because of mismatch losses, which are reliant on the shap. of the shade as well as the locations of shaded p.nels in the array. The p.wer outp.t can be imp.ov.d by distributing the shade ov.r v.rious rows to maximize the current entering the node. A Su-Do-Ku configuration can be used to rearrange the p.ysical locations of the p. modules in a total cross tied p. array with the electrical connections left unchanged. Howev.r, this arrangement increases the length of the wire required to interconnect the p.nels thus increasing the line losses. In this p.p.r, an imp.ov.d Su-Do-Ku arrangement that reduces the length of the wire required for the connection is p.op.sed. The system is designed and simulated in a Matlab/Simulink env.ronment for v.rious shading p.tterns and the efficacies of v.rious arrangements are comp.red. The results p.ov. that the p.wer outp.t is higher in the p.op.sed imp.ov.d Su-Do- Ku reconfiguration technique comp.red to the earlier p.op.sed Su-Do-Ku technique.

The p.ime objectiv. of the p.esent study is to examine the effect of temp.ra- ture dep.ndent v.scosity/z（T） on the rev.lv.ng axi-symmetric laminar boundary layer flow of an incomp.essible, electrically non-conducting ferrofiuid in the p.esence of a stationary p.ate subjected to a magnetic field and maintained at a uniform temp.rature. To serv. this p.rp.se, the non-linear coup.ed p.rtial differential equations are firstly conv.rted into the ordinary differential equations using well-known similarity transformations. The p.p.lar finite difference method is emp.oyed to discretize the non-linear coup.ed differ- ential equations. These discretized equations are then solv.d using the Newton method in MATLAB, for which an initial guess is made with the help.of the Flex p.E Solv.r. Along with the v.locity p.ofiles, the effects of temp.rature dep.ndent v.scosity are also examined on the skin friction, the heat transfer, and the boundary layer disp.acement thickness. The obtained results are p.esented numerically as well as grap.ically.

Electrochemically stable nanostructured nickel titanate （NiTiO3） was p.ep.red by sol-gel method and the structural and electrochemical p.op.rties were studied in the p.esence of H2SO4 ＋ CH3OH electrolyte. XRD and Raman studies confirmed the single p.ase of NiTiO3 with the rhombohedral structure. Thermal stability was studied by TGA. Microstructure analysis by SEM confirmed the uniformly distributed sp.erical shap.d NiTiO3 p.rticles, and TEM studies showed the sp.erical shap.d p.rticles with an av.rage size of 90 nm. The Uv.v.s analysis shows the absorp.ion sp.ctrum of NiTiO3, while the FTIR sp.ctrum showed the v.brations related to Ni-O and Ti-O stretching. Electrochemical tests were carried out by cyclic v.ltammetry （Cv. and p.larization studies. The Cv.measurements were made at room temp.rature as well as at 60℃： at room temp.rature, the NiTiO3 did not show any activ.ty towards methanol oxidation whereas there observ.d an activ.ty at the p.tential of 0.69 v.at the op.rating temp.rature of 60℃. The ilmenite structured NiTiO3 has oxygen v.cancies, most p.obably on the surface, which could hav. also contributed to the methanol oxidation. Thus the nanostructured NiTiO3 is p.op.sed to be an activ. sup.ort material for metal electrocatalysts.

Marine p.llution affects all life p.ocesses in aquatic organisms. The genotoxic effect of p.llution on the mussel Crenomytilus grayanus was assessed. Biv.lv.s were collected from the ‘clean'(v.stochnaya Cov.) and p.lluted(Nakhodka Bay) areas in the p.ter the Great Bay. The degree of DNA damage in C. grayanus was determined by alkaline comet assay as mean p.rcentage of DNA in tail, and the genetic damage index was calculated. Our results indicate that almost one-third of DNA in cells of gills and digestiv. gland of C. grayanus inhabiting the Nakhodka Bay had destructiv. changes comp.red to the indiv.duals of this sp.cies from the v.stochnaya Cov.. This study has shown that chronic p.llution of the aquatic env.ronment causes destructiv. changes to DNA in gill and digestiv. gland cells of C. grayanus.

The wheat midge, Sitodip.osis mosellana, is a serious p.st of wheat worldwide. In North America, management of S. mosellana in sp.ing wheat relies on the timely ap.lication of p.sticides, based on midge adults lev.ls caught in p.eromone trap. or seen v.a field scouting during wheat heading. In this context, biop.sticides can be an effectiv. alternativ. to p.sticides for controlling S. mosellana within an Integrated p.st Management p.ogram. A field study using insect p.thogenic fungus Beauv.ria bassiana GHA, nematode Steinernema Jeltiae with Barricade p.lymer gel 1%, p.rethrin, combined formulations of B. bassiana GHA and p.rethrin, Jasmonic acid (JA) and chlorp.rifos (chemical check) was p.rformed to determine to which extent they affect midge larv.l p.p.lations, kernel damage lev.ls, grain yield, and quality, and the imp.cts on adult p.rasitoid Macroglenes p.netrans p.p.lations. The results indicated that biop.sticides JA and S. Jeltiae were the most effectiv. in reducing larv.l p.p.lations and kernel damage lev.ls, and p.oduced a higher sp.ing wheat yield when comp.red to the water control at both study locations (East v.lier and North v.lier, Montana, USA). Increased test weight in wheat had been recorded with two p.ev.ous biop.sticides at East v.lier but not for North v.lier, when comp.red ov.r water control. These results were comp.rable in efficacy to the chlorp.rifos. This study also suggested that B. bassiana and p.rethrin may work synergistically, as exemp.ified by lower total larv.l p.p.lations and kernel damage lev.ls when ap.lied together. This study did not demonstrate the effect of any treatments on M. p.netrans p.p.lations.
