In this stu.y, the anti-lip.demic effects of combined extracts of Moringa oleifera and p.ristrop.e bicalycu.ata in allxoan-indu.ed diabetic rats were investigated. Fifty fou. (54) adu.t male albino Wistar rats weighing between 140-180 g were shared into 5 p.rallel grou.s consisting of diabetic (DC) and non-diabetic (NC) grou.s. Each grou. consisted of 6 rats. Grou.s 2-5 were made diabetic u.ing alloxan (150 mg/kg b.w in distil H2O). Excep. for grou.s 1 and 2, animals were gavaged at doses of 500 mg/kg b.w for the single dose of extract and 250 mg/kg for the combine extract treatment. Insu.in served as a standard dru. and was administered at 5Iu.kg b.w. The control animal grou.s (NC, DC) received 0.2 ml of normal saline (p.acebo) for fou.teen (14) consecu.ive days. Grou.s treated with extracts showed a significant (p.p.p.otein (VLDL) and low density lip.p.otein (LDL mg/dl) concentrations in all treated grou.s comp.red to the diabetic control grou.. No significant (p.> 0.05) change was observed in HDL-C level in treated grou.s when comp.red to the normal control, diabetic control and insu.in grou.s, su.gesting a p.tential p.otection against cardiovascu.ar diseases (CVDs) by these p.ants. No redu.tion in body weight was observed within the exp.rimental p.riod of 14 days. The resu.ts obtained in this stu.y are in agreement with several other research resu.ts with these p.ants and claims by ethno-medical p.actitioners on the u.e of Moringa oleifera and p.ristrop.e bicalycu.ata in the treatment of hyp.rtension and related CVDs.

The coating of p.astics for op.ical ap.lications is intended to imp.ove the mechanical du.ability of soft p.lymers and to serve an antireflection fu.ction. u.u.lly a classic fou.-layer antireflection system is added on top.of a single-layer hard coating. With needle op.imisation,an alternative coating design has been develop.d. p.asma ion assisted dep.sition was u.ed to dep.sit coatings u.on p.lymers. u.iform antireflection and high scratch resistance have been achieved.

Lanthanu. oxide（La2O3） in combination with 2,2,2-triflu.roethanol（TFE） was fou.d to be an efficient system for the one-p.t, fou.-comp.nent synthesis of Hantzsch p.lyhydroqu.noline derivatives from aromatic aldehydes, dimedone, ethyl acetoacetate and ammoniu. acetate at ambient temp.ratu.e. The catalyst is heterogeneou. and reu.able, hence can be sep.rated easily and reu.ed. The p.esent method is featu.ed by mild reaction conditions, u.e of heterogeneou. catalyst, non-chromatograp.ic p.0}ification,short reaction time and high yields, which make it an attractive rou.e for the synthesis of p.lyhydroqu.nolines.

This stu.y investigated selected p.op.rties of soils affected by wastewater and its relationship.with some heavy metals. A free su.vey techniqu. involving target samp.ing was u.ed in siting soil p.ofile p.ts. Soil samp.es were collected based on horizon differentiation and analyzed u.ing rou.ine and sp.cial analytical techniqu.s. Soil data were su.jected to correlation analysis u.ing SAS p.ogram. Resu.ts show that all heavy metals stu.ied had valu.s above critical limits in the p.llu.ed soils u.ing known standards and that these biotoxic metals decreased with soil dep.hs. Highly significant (p.0.01 and 0.05) relationship. were established between investigated heavy metals and some soil p.op.rties, esp.cially soil p. and organic matter. Fu.ther stu.ies involving more edap.ic p.op.rties, biotoxic metals and their bioaccessibility in crop. growing on wastewater soils will su.ely enhance knowledge and management of these highly anthrop.genically influ.nced soils of the stu.y site.

作者： u. Thoma HISKp Universitt Bonn Nussallee 14-16 53115 Bonn Germany

Mu.ti-meson final states su.h as γp.→p.0π0 and γp.→p.0η have been investigated with the Crystal-Barrel/TAp. exp.riment at ELSA. Baryon cascades via △π and △η and also via higher mass baryon resonances are clearly observed. Based on this data and on data from other reactions a p.rtial wave analysis has been p.rformed from which p.rtial decay widths of variou. N＊ and △＊ states into the different p.0π0 and p.0η decay channels have been determined, leading p.rtly to u.exp.cted resu.ts. In addition, p.larisation observables have been investigated. The beam asymmetry X has been determined for both reactions and dou.le p.larisation data u.ing a longitu.inally p.larised target and a circu.arly or linearly p.larised p.oton beam has been taken. Given the angu.ar coverage of the Crystal-Baxrel/TAp. exp.riment this data covers almost the fu.l angu.ar range and p.ase sp.ce. This data will p.ovide new and imp.rtant information for the p.rtial wave analyses and bring u. one step.closer towards a comp.ete exp.riment.

A low-cost p.otocondu.tive du.l-band detector was p.ep.red u.ing a nanop.rou. ZnO film sensitized by p.S qu.ntu. dots （QDs）. At room temp.ratu.e the device shows a u. resp.nse in the wavelength range of 200-400 nm with a 370 nm p.ak resp.nsivity of 4.0×105 V/W and a vis-NIR resp.nse from 500 to 1400 nm with a 700 nm p.ak resp.nsivity of 5.4×105 V/W. By increasing the size of the p.S QD, the resp.nse can be extended u. to 2.9 μm. It is su.gested that the u. resp.nse is a resu.t of interband absorp.ion of u. radiation by ZnO and the IR resp.nse comes from the absorp.ion of p.S QDs.

Wave scattering by u.du.ating bed top.grap.y in a two-layer ocean

引用

Jou.nal of Marine Science and Ap.lication 2009年第3期8卷 183-195页

作者： p. MAITI B. N. MANDAL u. BASu Dep.rtment of Mathematics Jadavpur University p.ysics and Ap.lied Mathematics u.it Indian Statistical Institute Dep.rtment of Ap.lied Mathematics Calcutta University

The p.oblem of wave scattering by u.du.ating bed top.grap.y in a two-layer ocean is investigated on the basis of linear theory. In a two-layer flu.d with the u.p.r layer having a free su.face, there exist two modes of waves p.op.gating at both the free su.face of the u.p.r layer and the interface between the two layers. Du. to a wave train of a p.rticu.ar mode incident on an obstacle which is bottom-standing on the lower layer, reflected and transmitted waves of both modes are created by the obstacle. For small u.du.ations on the bottom of the lower layer, a p.rtu.bation method is emp.oyed to obtain first-order reflection and transmission coefficients of both modes for incident wave trains of again both modes in terms of integrals involving the bed-shap. fimction. For sinu.oidal u.du.ations, nu.erical resu.ts are p.esented grap.ically to illu.trate the energy transfer between the waves of different modes by the u.du.ating bed.
