1煤矸石粉与传统填料沥青混凝土力学性能和环境影响的对比研究显示文摘由于自然资源日益枯竭,各行各业对于废物利用的需求显著增长。煤矸石是在煤的开采、加工过程中产生的副产品,其在自然环境中的累积引起了一系列经济和环境问题。为了研究煤矸石粉在道路工程中的适用性,通过马歇尔稳定度、间接拉伸强度、水稳定性、回弹模量和耐疲劳性能试验,对煤矸石粉热拌沥青混凝土与石灰石粉、沸石粉和普通硅酸盐水泥等传统填料热拌沥青混凝土进行力学性能对比。结果表明:与石灰石粉和沸石粉相比,煤矸石粉尤其是煤矸石灰作为填料改善了热拌沥青混凝土的力学性能,而煤矸石灰沥青混凝土和普通硅酸盐水泥沥青混凝土有几乎相同的力学性能。另外,采用毒性特征浸出程序(TCLP)来评价煤矸石粉沥青混凝土对环境的影响,结果表明:不同试验样品的重金属浓度在很大程度上小于标准值。因此将煤矸石粉作为填料应用在热拌沥青混凝土中不仅可以获得优良的力学性能,而且还可以有效减少煤矸石对环境的污染。冯新军(编译) 赵梦龙(编译) 李猛(编译) amir modarres morteza rahmanzadeh pooyan ayar 2017中外公路2017,37,5:9
2The potential of genetically-engineered pigs in providing an alternative source of organs and cells for transplantation显示文摘There is a critical shortage of organs, cells, and corneas from deceased human donors worldwide. There are also shortages of human blood for transfusion. A potential solution to all of these problems is the transplantation of organs, cells, and corneas from a readily available animal species, such as the pig, and the transfusion of red blood cells from pigs into humans. However, to achieve these ends, major immunologic and other barriers have to be overcome. Considerable progress has been made in this respect by the genetic modification of pigs to protect their tissues from the primate immune response and to correct several molecular incompatibilities that exist between pig and primate. These have included knockout of genes responsible for the expression of major antigenic targets for primate natural anti-pig antibodies, insertion of human complementand coagulation-regulatory transgenes, and knockdown of swine leukocyte antigens that stimulate the primate's adaptive immune response. As a result of these manipulations, the administration of novel immunosuppressive agents, and other innovations, pig hearts have now functioned in baboons for 6-8 months, pig islets have maintained normoglycemia in diabetic monkeys for > 1 year, and pig corneas have maintained transparency for several months. Clinical trials of pig islet transplantation are already in progress. Future developments will involve further genetic manipulations of the organsource pig, with most of the genes that are likely to be beneficial already identified.David K.C.Cooper Hidetaka Hara Mohamed Ezzelarab Rita Bottino Massimo Trucco Carol Phelps David Ayares Yifan Dai 2013The Journal of Biomedical Research2013,27,4:6
