1壳牌对未来车用能源多元化发展趋势的思考显示文摘面对能源短缺和环境污染的双重挑战,交通领域的转型升级不可避免。本文结合未来车用动力系统的发展趋势,对交通运输领域中应用的多种先进动力系统、清洁能源及替代燃料进行综述和评价,包括目前主要使用的传统液态化石燃料即汽、柴油及先进内燃机技术,清洁替代燃料(如生物燃料、天然气合成油(GTL)燃料、电转液(PTL)燃料、液化天然气(LNG)等),以及电气化动力系统(包括混合动力、纯电动和燃料电池)等,并着重讨论液体燃料。壳牌认为没有一种单一的解决方案可以解决复杂的能源问题,未来交通能源结构将呈现多种能源并存的特点,并分别适用于不同的场景。该文还介绍了壳牌近期基于不同政治、经济和社会发展程度提出的3种远景(壳牌“高山”、“海洋”和“天空”远景),提出壳牌对未来车用能源领域转型脱碳发展情景的思考。贾恬 郑彬 Warnecke W Kolbeck A Aradi A Kofod M Clark R Wilbrand K 2020汽车安全与节能学报2020,11,1:2
2Interaction between castanospermine an immunosuppressant and cyclosporin A in rat cardiac transplantation显示文摘AIM: To investigate the interaction between castanospermine and cyclosporin A(Cs A) and to provide an explanation for it.METHODS: The alkaloid castanospermine was prepared from the seeds of Castanospermum austral consistently achieving purity. Rat heterotopic cardiac transplantation and mixed lymphocyte reactivity were done using genetically inbred strains of PVG(donor) and DA(recipient). For the mixed lymphocyte reaction stimulator cells were irradiated with 3000 rads using a linear accelerator. Cyclosporin A was administered by gavage and venous blood collected 2 h later(C_2). The blood levels of Cs A(Neoral) were measured by immunoassay which consisted of a homogeneous enzyme assay(EMIT) on Cobas Mira. Statistical analyses of interactions were done by an acceleratedfailure time model with Weibull distribution for allograft survival and logistic regression for the mixed lymphocyte reactivity.RESULTS: Castanospermine prolonged transplant survival times as a function of dose even at relatively low doses. Cyclosporin A also prolonged transplant survival times as a function of dose particularly at doses above 2 mg/kg. There were synergistic interactions between castanospermine and Cs A in the prolongation of cardiac allograft survival for dose ranges of Cs A by castanospermine of(0 to 2) mg/kg by(0 to 200) mg/kg(HR = 0.986; 95%CI: 0.981-0.992; P < 0.001) and(0 to 3) mg/kg by(0 to 100) mg/kg(HR = 0.986; 95%CI: 0.981-0.992; P < 0.001) respectively. The addition of castanospermine did not significantly increase the levels of cyclosporin A on day 3 or day 6 for all doses of Cs A. On the contrary, cessation of castanospermine in the presence of Cs A at 2 mg/kg significantly increased the Cs A level(P = 0.002). Castanospermine inhibited mixed lymphocyte reactivity in a dose dependent manner but without synergistic interaction. CONCLUSION: There is synergistic interaction between castanospermine and Cs A in rat cardiac transplantation. Neither the mixed lymphocyte reaction nor the metabolism of Cs A provides an explanation.Adrian D Hibberd David A Clark Paul R Trevillian Patrick Mcelduff 2016World Journal of Transplantation2016,6,1:2
