Shearer and hydraulic support are matching equipments. To increase the operating speed of the shearer, the following speed of hydraulic support must be increased. This means increasing the volume of flow from emulsion power station. Analyzing the operating characteristics of hydraulic supports, the number of simultaneously operating supports is obtained by means of pressure parameter and time history at a certain time, which is a theory base for development of control system to multi-pump emulsion power station.

The chaotic ant swarm algorithm （CAS） is an optimization algorithm based on swarm intelligence theory, and it is inspired by the chaotic and self-organizing behavior of the ants in nature. Based on the analysis of the properties of the CAS, this article proposes a variation on the CAS called the modified chaotic ant swarm （MCAS）, which employs two novel strategies to significantly improve the performance of the original algorithm. This is achieved by restricting the variables to search ranges and making the global best ant to learn from different ants＇ best information in the end. The simulation of the MCAS on five benchmark functions shows that the MCAS improves the precision of the solution.

The genus Byssosphaeria from China was briefly reviewed based on specimen examinations and literature work. Taxonomic and nomenclatural problems are discussed. Among the previously recorded taxa of the genus, a new combination, Byssosphaeria hainanensis, is made and a new Chinese record, B. alnea, is reported. A key to the known species of the genus in China is provided.

Objective To investigate the attenuating effect of curcumin, an anti-inflammatory compound derived from dietary spice turmeric （Curcuma longa） on the pro-inflammatory insulin-resistant state in 3T3-L1 adipocytes. Methods Glucose uptake rate was determined with the [3H] 2-deoxyglucose uptake method. Expressions of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） were measured by quantitative RT-PCR analysis and EliSA. Nuclear transcription factor kappaB p65 （NF-r,B p65） and mitogen-activated protein kinase （MAPKs） were detected by Western blot assay. Results The basal glucose uptake was not altered, and curcumin increased the insulin-stimulated glucose uptake in 3T3-L1 cells. Curcumin suppressed the transcription and secretion of TNF-α and IL-6 induced by palmitate in a concentration-dependent manner. Palmitate induced nuclear translocation of NF-kB. The activities of Jun NH2-terminal kinase ONK）, extracellular signal-regulated kinasel/2 （ERKI/2） and p38MAPK decreased in the presence of curcumin. Moreover, pretreatment with SP600125 （inhibitor of JNK） instead of PD98059 or SB203580 （inhibitor of ERKI/2 or p38MAPK, respectively） decreased the up-regulation of TNF-α induced by palmitate. Conelusion Curcumin reverses palmitate-induced insulin resistance state in 3T3-L1 adipocytes through the NF-kB and JNK pathway.

AIM To observe the effects of ricin (RT) with and without chemical modification on both hepatotoxicity of mice and activity against hepatocellular cancer (HCC), and evaluate the possibility to improve RT anticancer activity via chemical *** RT was modified with N-succinimidyl3-(2-pyridyldithio) propionate (SPDP), a heterobifunctional cross-linker, and SPDP derivative of RT (PDP-R) was obtained. The serum glutathione-s-transferase (SGST) activity, as an index of liver damage, was determined in mice intoxicated with RT and PDP-R, at various doses and time. The tissue damage of HCC in the nude mice ip injected with PDP-R was compared with that with RT at the same dose by immunohistochemical method, the relative content of both RT and PDP-R in the HCC tissues was measured by computerized *** The SGST activities increased with doses or/and time intoxicated with both RT and PDP-R, and the increase in the value of RT group was more significant than that in the PDP-R group; the SGST activity of RT group was 2.8-fold (P＜0.01) of PDP-R group at a dose of 12.5μg/kg for 42h, showing the much lower toxicity of R-PDP than that of RT. Under an optical microscope, hemolysis and necrosis of massive cells in the HCC tissues of PDP-R group were observed and the ratio of necrosis mounted to 90.5% while the corresponding value of RT group only to 62.5%. With computerized image-analysis, the average relative content of RT and PDP-R in the HCC tissues, represented as greyness, was 140.06±3.43 and 169.10±2.74, respectively. There was significant difference between the two (P＜0.05), indicating the higher content of PDP-R in the HCC tissue than that of *** The hepatotoxicity of PDP-R to mice may be reduced by chemical modification with SPDP, but both the affinity of PDP-R to the HCC tissues and ability to kill it may be stronger than that of RT. So this might be a valuable attempt to improve the anticancer activity of RT.

Four kinds of rare earth oxides, lanthana, ceria, praseodmia andneodgmia are separately added to a nickel catalyst Ni/γ-A12O3) aspromoters. The formed nickel catalysts, NRL, NRC, NRP, NRN, have atypical structure of mezzanine that is unfit for carbon deposition on nickelcatalyst. They show higher selectivity with lower carbon deposition, whichcan be ascribed to high reforming the and low carbon formation rate.

通过建立锂电解槽电解质-氯气气液两相流二维模型,使用标准k-ε两方程模型耦合欧拉-欧拉模型求解不同极间通道内电解质速度与体积分数分布,研究电流密度均匀和不均匀分布对气体分率与液相速度的影响。结果表明:均匀模型的体积分数和液相速度均大于非均匀模型;对不同结构和操作参数的分析发现,缩短极距能够降低体积分数,使侧面极间通道内电解质速度增加,中间极间通道内速度下降;增大阳极半径,体积分数与液相速度均下降;增加电解质液面高度对两者的影响不大,增大电流则会使两者增加。

AIM: To observe the effects of three cytokines on the apoptosis of Tf-1 cells induced by y irradiation and investigate the relationship between apoptosis and caspase-3 activity. METHODS: Different cytokines GM-CSF, IL-3 and GM-CS/IL-3 fusion protein were added into the irradiated Tf-1 cells. MTT assay, morphology, flow cytometry, and DNA fragmentation assay were used to observe the effects of cytokines on apoptosis. The caspase-3 activity was determined with a fluorocytometer. RESULTS: Irradiated Tf-1 cells showed typical morphological characteristic of apoptosis demonstrated by transmission electron microscopy and were accumulated in G0/G1 phase. In the groups treated with growth factors after irradiation, three cytokines significantly increased the viability rate, distinctly decreased the apoptosis rate and the proportion of DNA fragmentation. When Tf-1 cells were irradiated by y
