A promising microalgal strain isolated from fresh water,which can grow both autotrophically on inorganic carbon under lighting and heterotrophically on organic carbon without lighting,was identified as Chlorella ***-01 with the phylogenetic analysis based on 18S ribosomal ribonucleic acid(rRNA)gene *** the heterotrophic batch culture,more than 20.0 g·L^(-1)of cell dry weight concentration(DWC)of Chlorella ***-01 was obtained at day 5,and which was used directly to seed the autotrophic culture.A novel fermentor-helical combined photobioreactor was established and used to cultivate Chlorella ***-01 for the fixation of carbon dioxide(CO_(2)).It showed that the autotrophic growth of Chlorella ***-01 in the combined photobioreactor was more effective than that in the fermentor alone and the maximum DWC of 2.5 g·L^(-1)was obtained at day *** highest CO_(2)fixation of 95%appeared on day 1 in the exponential growth phases of Chlorella ***-01 and 49.8%protein was found in the harvested microalgal cells.

It has been reported that organotins can inhibit the proteasomal chymotrypsin-like activity and induce cell death,but the interaction mode of organotins with proteasome has not been well *** this study,the IC50 of butyltins and phenyltins against the proteasomal activity and the nature of their inhibition were *** was found that both mono-and di-organotins were weak,reversible inhibitors against the proteasome,while tributyltin and triphenyltin were potent,irreversible proteasome *** silico studies using the reversible organotin proteasome inhibitors demonstrated a tight correlation of the estimated proteasomal inhibition constants(Ki) with the experimental IC50 values for proteasome ***,the Sn atom in TBT and TPT was found susceptible to form a coordinate bond with Thr 1 OY of the β5 subunit,which may account for the irreversible proteasome *** computational docking approach well predicted the inhibition nature of organotins toward the proteasomal chymotrypsin-like *** predictive model might aid in understanding the cytotoxic behavior of similar organometallic compounds.

The hydrogen storage properties of Ti1.2Fe+xCa (x=1%, 3% and 5% in mass fraction) alloys was investigated. Results stow that the modified alloys can be activated without any thermal treatment at room temperature due to the addition of Ca and excess Ti in (lie alloys. Hydrogen storage properties of these modified alloys vary with Ca amount and reaction temperature. In addition, the influence mechanism of the addition of Ca and excessive Ti on the activation behavior and hydrogen storage capacity of the alloys was discussed.

针对方向图可重构天线阵列的稀疏布阵问题,提出一种基于扩展酉矩阵束算法的优化设计算法。首先建立以阵元位置和多组激励为变量的多方向图联合稀疏优化模型,并利用期望方向图采样数据构建Hankel块矩阵。然后通过centro-Hermitian化处理和酉变换将采样矩阵从复数域转换到实数域,舍弃实矩阵中较小的奇异值对可重构线阵进行稀疏。最后通过对等价矩阵束的广义特征值分解估计稀布阵元位置,进而得到每个方向图对应的激励。仿真验证了该方法能够以阵元非均匀稀疏分布的阵列形式有效实现多个方向图的精确重构。
