4籼粳不育新位点的发现及其遗传分析显示文摘粳稻02428携有S-5n广亲和基因,然而与籼稻IR24杂交表现为半不育。对02428与IR24.Pecos、秋光等品种杂交的分离世代的小穗育性进行遗传分析,结果表明:02428与IR24之间的不育性受单基因控制,遗传规律符合单位点孢子体一配子体遗传模式,不育性由非S-5的新位点引起,美国品种Pecos具有复等位的中性基因;RFLP标记技术检测后初步确定,该新不育位点在第11染色体上的标记G24附件,与目前已报道的不育位点都不等位,新位点暂定名为S-p(t)。研究结果还显示,粳稻品种秋光与籼稻品种IR24之间的不育性受2个不育位点S-5和S-p(t)控制,其遗传效应表现有累加作用。朱旭东 王建林 钱前 张小惠 曾大力 朱立煌 闵绍楷 熊振民4 was controlled by two S-1oci S-5 and S-p(t) and its genetical effect was 1998Acta Genetica Sinica1998,25,3:10
5Toxicity Evaluation of Freshwater Cyanobacterium Microcystis aeruginosa PCC 7806: Ⅱ Nephrotoxicity in Rats显示文摘Nephrotoxic potential of laboratory cultures of freshwater cyanobacterium (blue-green al ga) Microcystis aeruginosa PCC 7806 (Pasteur Institute) was assessed in male rats. The ani mals were injected intraperitoneally with 0. 5, 1. 0 and 2. 0 LD50 doses of lyophilized cell ex tract. Elevated plasma urea and creatinine levels were accompanied by decrease in protein and albumin levels, followed by hematuria, proteinuria and bilirubinuria. Also decrease in kidney lactate dehydrogenase and glutamic oxaloacetic transaminase indicated possible nephrotoxic po tential of the cyanobacteria. The extract also produced various hematological changes associat ed with stagnant type of hypoxia. High perfomance liquid chromatography of the culture I dentified the active principle (toxin) asR.

6EFFECT OF OVERLAPPING TREATMENT ON MICROSTRUCTURE OF LASER-CLAD WC/Ni60A COMPOSITE COATING显示文摘The effect of overlapping treatment on microstructure of laser clad WC/Ni60A composite coating was studied with XRD, SEM, TEM and SAED etc. The results show that during the overlapping treatment the existence of the residual heat and edge angle effect on the substrate has changed the composition and microstructure of the coating by raising the fusion temperature and increasing the dilution degree of the coating.C.Z.

7Selected issues at the interface between nuclear physics and astrophysics as well as the standard model显示文摘The density functional theory (DFT) with a minimal number of parameters allows a very successful phenomenological description of ground state properties of nuclei all over the periodic table. The recent developments on the application of the covariant density functional theory as well as its extensions by the group in Beijing for a series of interests and hot topics in nuclear astrophysics and nuclear structure are reviewed, including the rapid neutron-capture process, Th/U chronometer, and isospin corrections for superallowed β transitions.MENG Jie1,2,3, NIU ZhongMing1, LIANG HaoZhao1 & SUN BaoHua2,4 1State Key Laboratory of Nuclear Physics and Technology, School of Physics, Peking University, Beijing 100871, China 2School of Physics and Nuclear Energy Engineering, Beihang University, Beijing 100191, China 3Department of Physics, University of Stellenbosch, Stellenbosch, South Africa 4Justus-Liebig-Universita¨t Giessen, Heinrich-Buff-Ring 14, Giessen 35392, Germany 2011Science China(Physics,Mechanics & Astronomy)2011,54,S1:5
8Bone Density and Mechanical Properties in Femoral Bone of Swim Loaded Aged Mice显示文摘Effects of swirnming on bone density and mechanical properties of femur were investigated in aged male and female mice. R/1 strain of senescence accelerated mouse (SAM) at eleven months old was used. Two groups of males and two groups of females each consisting of 7 mice were used. One male and one female groups were loaded with a swim regiment of 40 min a day, 5 days a week for 6 consecutive weeks. The remaining groups were used as the controls. All mice were fed with the standard diet and water ad libitum during the experiments.The results of this study indicated that (i) the hady weight was significantly (P<0.05) lower in the swimming groups than in the control groups in boh sexes. (ii) The bone density was significantly higher (P <0.05) in the swimming groups than in the control groups in boh sexes. However, there was no sighficant difference in cortical thickness index. (iii) In the mechanical properties of bone, there were no significant differences in the level of the maximum breaking force, the ultimate stress and the deformation between the swimndng and the contro groups in beth sexes. However, the elasticity of the bone of the female hoce in the swimming group was significantly higher (P<0.05) than that of the control group.These results suggest that regimented swimming for the aged mice might suppress age-associated bone loss, and the effect of exercise in the females is greater that in the males.AKIO HOSHI HIROMI WATANABE MOMOKO CHIBA AND YUTAKA INABA (Department of Health and Physical Education, Nippon Dental University, 1-8-2 Fu-jimi, Chiyoda-ku, Tokyo, Japan )(Department of Health and Physical Education, Nippon Dental University, Fugimi, T 1998Biomedical and Environmental Sciences1998,11,3:4

10Oxygen Atom Exchange Mechanism in Reaction of OH Radical with AsO显示文摘Oxygen atom exchange reaction mechanism in the reaction of OH radicals with AsO was investigated by means of the density functional theory (DFT) with 6 311++G( 3df,3pd ) and 6 311++G( d,p ) basis sets. The calculated results suggest that the reaction between OH and AsO should make the oxygen atoms exchange rapidly because the barrier to isomerization is significantly less than the HO-AsO bond dissociation energy.CHI Yu-juan 1, YU Hai tao 1,2** , FU Hong gang 1,2 HUANG Xu ri 2, LI Ze sheng 2 and SUN Chia chung 21.

11FINITE ELEMENTS FOR THE LUBRICATED CONTACT BETWEEN SOLIDS IN METAL FORMING REOCESSES显示文摘In this paper, the lubrication problem in nmmerical sindation of forming processes is considered.After enumerationg the difficulties encountered when trying to solve such a problem with the finite element method, a generalization of the formaulation of Liu[4-6] for the thin film hydrodynamic lubrication re- gime is presented. This method is then aplied to a strip rolling simulation,using the Arbitrary La- grangian eulerian (ALE) formalism.R. Boman and J. - P.

13MULTIPLIERS AND TENSOR PRODUCTS OF WEIGHTED L^p-SPACES显示文摘Let G be a locally compact unimodular group with Haar measure rmdx and ω be the Beurling’s weight function on G (Reiter, [10]). In this paper the authors define a space Aωp,q (G) and prove that Aωp,q (G) is a translation invariant Banach space. Fur- thermore the authors discuss inclusion properties and show that if G is a locally compact abelian group then Aωp,q (G) admits an approximate identity bounded in Lω1 (G). It is also proved that the space Lωp (G) Lω1 Lωq (G) is isometrically isomorphic to the space Aωp,q (G) and the space of multipliers from Lωp (G) to Lq-1, (G) is isometrically isomorphic to the dual of the space Aωp,q (G) iff G satisfies a property Ppq. At the end of this work it is showed that if G is a locally compact abelian group then the space of all multipliers from Lω1 (G) to Aωp,q (G) is the space Aωp,q (G).S.
