针对大耳沙蜥在沙子中的运动行为,以球形物体为研究对象,利用3维离散元数值模拟程序LIGGGHTS模拟了旋转运动模式对颗粒物质中球形物体平动和上升/下降行为的影响,定量分析了旋转速度以及颗粒间摩擦系数等因素的具体影响.研究结果表明:球形物体与颗粒物质基底颗粒间的摩擦系数以及球形物体的自转角速度对球形物体的运动有明显影响,摩擦系数越大物体运动越明显,自转角速度越大物体运动越明显.该结果比较好地解释了沙漠生物外表具有鳞片的原因.

基于汽车等速100 km油耗、最高车速和0~100 km/h制动距离等基本技术性能指标,以及发动机排量、整车质量和售价等参数构建技术性能指标H、综合参数W和性价比N,形成多维综合评价方法,并提出一种以W为特征参数的汽车标识方式。在此基础上,对我国汽车市场主要品牌车型的技术性能、性价比等参数与销量之间的相关性进行研究。研究结果表明:不同品牌及车型的技术性能存在明显差异,合资品牌汽车技术性能比国产品牌的优,但性价比却显著比国产品牌的低;消费者对轿车、SUV和MPV的选择标准也存在差异,消费者选购轿车时更看重产品的技术性能和品牌;选购SUV时,消费者更关注产品的综合性能,而选购MPV时,消费者则更注重产品的实用性和性价比;高性能小排量发动机、高容量电池和电机系统、汽车轻量化与智能化及驱动技术(油电混合、增程式,尤其是四驱技术,驱动与制动系统一体化)的重大突破有望促成我国汽车产业跨越式发展。

作者： Adi Wolfson Nadia Komyagina Christina Dlugy Janine blumenfeld Green Processes Centre Chemical Engineering Department Sami Shamoon College of Engineering

Vegetable oil was successfully used as solvent and acyl donor in the kinetic resolution of several secondary alcohol racemates yielding high enantioselectivities. Using vegetable oil as solvent and acyl donor allowed easy separation of the pure alcohol enantiomer by extraction with methanol, by distillation under reduced pressure, or by column chromatography.

The extent of participation and changes of glycophorins (GPs) and membrane proteins in the merozoite-human erythrocyte interaction during the invasion of Plasmodium falciparum (Pf) were studied by immunobiotting techniques. Polycional antisera to αGP and to its C-terminal fragment (residues 82-131) as well as M and N specific monoclonal antibodies (MoAbs) were used. We examined the GPs in the parasite-free saponin lysates, saponin pellets and the culture supernatants of the infected erythrocytes in comparison with the mock cultured normal RBC. Excepting the usual GP patterns, a GP with molecular weight of 77.5 K (band 1’) existed in the parasitized erythrocytes and their saponin pellets and several GP bands ranging from 28K to 54K were present in saponin pellets when probed with anti-GP and anti-peptide C sera. This reflected the disintegration of erythrocyte membrane αGP through the invasion of Pf. The α2GP in the saponin pellets of the parasitized MM erythrocytes surprisingly cross-reacted with the N MoAb, implying that it may have come from the intermingling of the host αGP in MM erythrocytes with the parasite αGP reacting to N MoAb. The saponin pellets of parasitized erythrocytes preserved a considerable amount of ankyrin, band 3, protein 4.1 and 4.2, while the GP bands were densely mixed with the parasite proteins and the disintegrated products of membrane proteins. Four erythrocyte-binding antigens (EBA) of 143K, 135K, 115K and 107K recognized by malaria hyperimmune serum were detected in the culture supernatants of Pf, some of them appeared in the infected erythrocytes, their saponin lysates and pellets.

作者： y Q Lu J F Liu R L Nagel O O blumenfeld Department of Biochemistry Hunan Medical College Changsha Department of Medicine Division of Hematology and Department of Biochemistry Albert Einstein College of Medicine Bronx New York 10461 U.S.A.

We have examined the extent of glycophorin (GP) polymorphism in normal and abnormal human red cell membranes using immunoblotting technics and the following probes: Polyclonal anti-α GP that detects α and δ GP; antiserum to the C-terminal fragment of α GP (residues 82-131) that detects δ GP and all others that differ from α GP in the C-terminal region; and M and N specific monoclonal antibodies detecting the N-terminal octapeptide that specify M and N serological phenotypes. Red cells from 41 Central African normals displayed an invariant profile among all but 5. The invariant profile consisted of monomer and dimer of (M,N) GP and of δ (S,s) GP, γ GP and two other minor components, one of which had not been described before. The five abnormal profiles included two Central Africans with lack of δ GP, most likely S-s-U- serological phenotype which has a 4.9% incidence among them. In three other black individuals differences in the γ GP observed were not previously reported. α GP of all individuals reacted with M and N specific antibodies in accordance with their serologically determined M and N phenotypes, and in all individuals δ GP reacted with the N-specific monoclonal antibody. Only one case of sickle cell disease out of 54 Caucasian and black hematological patients showed a variant GP band (band 3a), the others had all normal pro files, including red cells from whole blood or density-defined fractions in Hb SS patients. Our impression is that GP polymorphism is infrequent among Caucasians but comparatively frequent among Central Africans. Moreover, immunoblotting technics confirmed the presence of Stα glycophorins in the erythrocytes of 5 members from a Japanese family.
