Coxsackievirus and tritiated water were added to municipal sludges which were placed on lysimeters containing sandy soil or clay soil. It took 23 weeks during a normal Danish winter to inactivate virus from an initial 106tcid50/g sludge to a not demonstrable level. Irrespective of sludge and soil type no virus was demonstrated in the leachate water. The rainfall during December–May was 300 mm. 相似文献

We present a predictive method that can simulate an essentialstep in the antigen presentation in higher vertebrates, namelythe step involving the proteasomal degradation of polypeptidesinto fragments which have the potential to bind to MHC ClassI molecules. Proteasomal cleavage prediction algorithms publishedso far were trained on data from in vitro digestion experimentswith constitutive proteasomes. As a result, they did not takeinto account the characteristics of the structurally modifiedproteasomesoften called immunoproteasomesfoundin cells stimulated by 相似文献

The similarity of the histopathologic changes in posttraumatic synovitis and osteoarthritis suggests that similar etiologic agents, possibly macro- and microtraumata, were pathogenetic factors in common. 相似文献

In this paper a new modified processing route for deep drawing has been proposed for producing long cylindrical cups from 12 mm thick circular blanks of Aluminium (Al)-killed AISI 1010 steel, without blank-holder. In this modified route, flat blanks were fabricated to a preformed shape by stamping operation and then followed by multistage drawing processes to increase depth of the cups. Wall ironing was also purposefully included in each draw step with deep drawing processes to reduce wall thickness and earing tendency on cup edges. Thus, evolution of wall thickness distribution, drawability and ironability parameters, punch force history, microstructures and strain distribution profiles on outer cup surfaces were obtained as effects of interaction between processes, tools and material in the investigation. The overall draw stages showed: LDR 2.06; overall draw reduction >50% with a drawing efficiency ~72%; LIR 3.55; overall ironing reduction >70% with an ironing efficiency ~68%, which were achieved in the experimental works. 相似文献
