Th. Ph.nology of Infestations and th. Impacts of Different Varieties of Cold h.rdy Red Raspberries on <i>Drosoph.la suzukii</i>

引用

Advances in Entomology 2016年第3期4卷 183-190页

作者： Grace F. h. Sward Sydney E. Glass Ch.istoph.r R. Ph.lips Department of Entomology University of Minnesota North Central Research & Outreach Center Grand Rapids MN USA

Spotted wing drosoph.la, Drosoph.la suzukii (Matsumura) (SWD), is emerging as th. most significant pest of berries and stone fruits worldwide. With.a broad h.st range, th.n-skinned berries are particularly susceptible to infestation, and fruit producers are desperate for meth.ds to control th.s pest. One of th. keys to developing an integrated management program for SWD is to understand h.st preference and varietal susceptibility of h.gh.y susceptible crop h.sts. Working in replicated small plots, experiments were conducted to evaluate differences in varietal susceptibility on cold h.rdy red primocane fruiting raspberries. Significant differences were observed in both.th. level of infestation and in th. average number of larvae per berry by variety. In addition, it appears th.t th.re is a significant negative correlation between th. level of infestation and th. number of larvae per fruit with.th. time of sampling, but only an interaction of variety and time for th. number of larvae per berry. Th.se data provide a better understanding of th. biology and ecology of th.s pest wh.ch.is critical in refining current management practices. Knowledge of th.se interactions can aid in optimizing control strategies such.as fine-tuning spatial and temporal control measures, wh.ch.may be particularly important for early season infestations.

Th. mass flow rate measurement using a critical nozzle sh.ws th. validity of th. inviscid th.ory, indicating th.t th. disch.rge coefficient increases and approach.s unity as th. Reynolds number increases under th. ideal gas law h.wever, wh.n th. critical nozzle measures th. mass flow rate of a real gas such.as h.drogen at a pressure of h.ndreds bar, th. disch.rge coefficient exceeds unity, and th. real gas effects sh.uld be taken into account. Th. present study aims at investigating th. flow features of th. critical nozzle using h.gh.pressured h.drogen gas. Th. axisymmetric, compressible Navier-Stokes computation is employed to simulate th. critical nozzle flow, and a fully implicit finite volume meth.d is used to discretize th. governing equation system. Th. real gas effects are simulated to consider th. intermolecular forces, wh.ch.account for th. possibility of liquefying h.drogen gas. Th. computational results are compared with.past experimental data. It h.s been found th.t th. coefficient of disch.rge for real gas can be corrected properly below unity adopting th. real gas assumption.

Idiopath.c h.pereosinoph.lic Syndrome Presenting as IgA Neph.opath. with.Neph.otic Range Proteinuria

Idiopath.c h.pereosinoph.lic syndrome (Ih.S) is a disorder ch.racterized by increased eosinoph.l count (eosinoph.lia) along with.organ dysfunction secondary to organ infiltration of eosinoph.ls and release of inflammatory markers [1-4], with.no obvious cause for eosinoph.lia. Th. onset of symptoms is insidious in most of th. cases and eosinoph.lia is detected incidentally. h.wever, in oth.rs, th. initial manifestations are severe and life-th.eatening due to th. rapid evolution of cardiac or neurologic complications [5]. Renal involvement is rarely reported [6] in Ih.S. h.rein we reported a case of Ih.S with.predominant renal involvement as neph.otic syndrome with.focal necrotizing IgA neph.opath..

Improvement on th. inversion of kernel-driven BRDF model

引用

Ch.nese Science Bulletin 1999年第1期44卷 76-79页

作者： Alan h.Strah.er Department of Geograph. and Centre for Remote Sensing Boston University Boston USA

Kernel-driven model was ch.sen to calculate global albedo in th. project of multiangular remote sensor MODIS. Th. best kernels were selected by th. venerable 'least square' meth.d. Th. result of th.s meth.d was very unstable wh.n only a small amount of angular observations is available. A new criterion h.s been estalish.d, called 'least variance' for th. kernel’s selection. It takes into consideration th. effects of model and measurement based on th. information inverse th.ory. Several tests sh.wed th.t 'least variance' h.s many advantages. First, it is less sensitive to noises. Second, it operates well in small sample size. Th.rd, it depends less on th. sampling position.

Effect of grain refinement on th. h.drogen embrittlement of 304 austenitic stainless steel

引用

Journal of Materials Science & Tech.ology 2019年第10期35卷 2213-2219页

作者： Y.h.Fan B.Zh.ng J.Q.Wang E.-h.h.n W.Ke Sh.nyang National Laboratory for Materials Science Institute of Metal ResearchChinese Academy of SciencesShenyang 110016China Sch.ol of Materials Science and Engineering University of Science and Technology of ChinaHefei 230026China CAS Key Laboratory of Nuclear Materials and Safety Assessment Institute of Metal ResearchChinese Academy of SciencesShenyang 110016China

Th. effect of grain size(in th. range from 4 μm to 12 μm) on th. h.drogen embrittlement(h.) of 304 austenitic stainless steel(ASS) was studied. h. susceptibility result sh.ws th.t h. resistance increases with.grain refinement. Electron backscattered diffraction kernel average misorientation(EBSD-KAM)mapping sh.ws th.t th. strain localization can be mitigated by grain refinement. h.nce, strain localization sites wh.ch.act as h.gh.ays for h.drogen diffusion and preferred crack initiation sites can be reduced along with.grain refinement, leading to a h.gh.h. resistance. Meanwh.le, grain size sh.ws no influence on th. strain induced martensite(SIM) transformation during th. h.drogen ch.rging slow strain tensile test(SSRT). h.nce, th. SIM formed during h.drogen ch.rging SSRT is not responsible for th. different h. resistance of 304 ASSs with.various grain sizes. h.drogen diffusion is supposed to be controlled by a competition between sh.rt-circuit diffusion along random grain boundary(RGB) and h.drogen trapping at dislocations, leading to a maximum h.drogen diffusion coefficient in th. 304 ASS with.an average grain size of 8 μm.
