摘要：HCSB-DEMO concept design is carried out at *** order to handle power from a core plasma region,a super-X divertor is preliminarily designed and investigated for *** increases the target surface area by expanding the magnetic flux surface with another X-point generated near the targets and increases the parallel connection length by moving the outer divertor target to larger R and *** heat load at the targets is investigated by *** heating power flowing into SOL/divertor regions being P=600 MW,when the density at the separatrix is ne=3.5×10^(19) m^(-3),the peak heat load at the inner and outer divertor is 9.2 MW/m^(2) and 3.7 MW/m^(2),respectively,which is much less than those of the standard divertor without impurity seeding,and also below the design targets(10 MW/m^(2)).Thus the super-X divertor may work well for HCSB-DEMO to solve the high heat load problem at the divertor target without impurity seeding from this preliminary concept design and simulation.

摘要：Mycobacterium tuberculosis FabH, an essential enzyme in mycolic acids biosynthetic pathway, is an attractive target for novel anti-tuberculosis agents. Structure-based design, synthesis of novel inhibitors of mtFabH was reported in this paper. A novel scaffold structure was designed, and 12 candidate compounds that displayed favorable binding with the active site were identified and synthesized. 2009 Song Li.

摘要：A conceptual design study of the HL-2M facility has shown that one can create not only a standard single-null divertor configuration on it,but also a second-order null(snowflake(SF))*** the SF divertor,the magnetic flux expansion closes to the separatrix and exceeds that of the standard configuration by more than a factor of 4 at the outer *** heat load at the divertor targets of this innovative configuration has been investigated by using *** is shown that the heat load it targets is different from that of the standard *** a result of the magnetic flux expansion,the peak heat load reduces and does not concentrate on a small area near the *** heat load profile becomes flat as compared to the standard *** the upstream density is 2.0×10^(19)/m^(3) with 10 MW heating power flowing into the SOL/divertor regions,the peak load at the outer divertor is 1.64 MW/m^(2) for the SF divertor,but it is 3.2 MW/m^(2) for the standard divertor,so the SF divertor can mitigate the heat load at the divertor targets when HL-2M operates at low plasma density and high heating power.

摘要：Twenty-three 1-(1H-1,2,4-triazole-1-yl)-2-(2,4-difluorophenyl)-3-(N-cycloproyl-N-substituted-amino)-2-propanols were designed and synthesized on the basis of the active site of lanosterol 14α-demethylase. In vitro antifungal activities showed that some of the title compounds had higher antifungal activity and broader antifungal spectrum than fluconazole.
