Attenuation of neutral beam injection is analyzed numerically under different plasma conditions： different plasma densities, beam energies, electron temperatures, and impurity concentrations. Both optimized plasma density and beam energy for plasma heating are obtained.展开更多

Site directed mutagenesis was explored to change the Shine Dalgarno Sequence from AAAAATGGGG (mutant type) to AAAAAGGGGG (wild type) in recombinant plasmid PSM604. The single base substitution made the plasmid with wild SDS unstable in structure and segregation. The interaction of SDS with subtilisin leader sequence of PSM604 might be responsible for the instability of plasmid.展开更多

DA containing neurons are found in i） the mesolimbic system in which cell bodies in the ventral tegmental area （VTA） project axons into the amygdala, cortex, hippocampus and the nucleus accumbens; and ii） the nigrostriatal system in which cell bodies located in the substantia nigra pars compacta send their axons into the dorsolateral parts of the striatum （Bjorklund and Dunnett, 2007）. The central noradrenergic neurons are concentrated in distinct brainstem nuclei with the locus coeruleus （LC） being the most prominent nucleus which projects a diffusely arborizing axonal network to most areas of the CNS （Szabadi, 2013）.展开更多
