在阻尼器中应用不同的形状记忆合金材料,使结构具有有效的耗能及恢复能力。采用不同方法,将4个阻尼系统应用到抗震结构系统当中。利用改进的破坏指示器对结构系统性能进行评测对比。结构损伤、非结构性损伤和系统中其他部件的永久变形在不同的地面加速度时程中都予以考虑。结果表明,甚至在剧烈地面运动之后,s.a.尼器在减少残余变形方面仍然非常有效。

关键词：阻尼器形状记忆合金被动控制地震激励损伤指数

To evaluate the potential of fungi from Darband cave,semnan,Iran,for valuable antibacterial and anticancer agents,molecular screening was done against polyketides(PKs);the source for numerous diverse secondary *** were isolated from soil and *** antibacterial activity of the isolates was studied against indicator bacteria by well diffusion agar method,and analyzed by PCR for PKs *** positive strains were compared for toxicity against indicators.a.d A549 *** of antibacterial agents was investigated in 26 days followed by partial purification of the *** layer chromatography(TLC)and High Performance Liquid Chromatography(HPLC)analyses were done to reveal the nature of the toxin(s).The isolates exhibited the antimicrobial activity against s.a.hylococcus.a.reus,Bacillus cereus.a.d Bacillus *** isolates selected for further studies based on the yellow culture broth,the presence of PKs.a.d antibacterial *** strains were identified as Penicillium chrysogenum using 18s rDNA *** yellow culture,87%identity of the PKs 12/PKs 13,the results of HPLC,and the toxic effects.a.ainst certain bacteria and A549 cells confirmed the production of the sorbicillinoid in *** strains;DDFCC170 and *** partially-purified antibacterial-anticancer agents named as.a.Ba170 and AnBa186 exhibited bactericide effect on *** and *** compounds killed A549 cells with an IC_(50) value of 0.25μM and 0.22μM ***170 and AnBa186 are attractive for pharmaceutical *** on the literature,the cytotoxicity of sorbicillinoids.a.ainst tumor cells.a.d bacteria is related to their oxidation capacity.

Open Journal of Applied sciences 2014年第5期4卷 225-233页

作者： Khadijeh abolmaali Masoumeh Rashedi Bita Ajilchi Department of Psychology Faculty of Human Science Science and Research Branch University Islamic Azad University (IAU) Tehran Iran Department of Psychology Roudehen Branch Islamic Azad University Roudehen Iran Department of Psychology Saveh Branch Islamic Azad University Saveh Iran

This res.a.ch explains.a.ademic achievement based on the personality characteristics, the psycho-social climate of the classroom in terms of academic engagement in mathematics. The population was high schoolboys.a.d girls in Damghan city in Iran. Participants were randomly selected using a multi-s.a.e cluster method (513 boys.a.d girls) and they simultaneously completed three questionnaires: academic engagement, the psycho-social climate of the classroom and personality characteristics. Path analysis was used to analyze data. The results showed that the direct effects of personality characteristics.a.d psycho-social climate of the classroom on academic achievement were not significant. The direct effects of openness, conscientiousness.a.d psycho-social climate of classroom on academic engagement were significant. The indirect effects (with mediation of academic engagement) and overall effects of openness, conscientiousness.a.d psycho-social climate of classroom on academic achievement were significant, also the effect of academic engagement on academic achievement was significant.

关键词： Academic Achievement Personality Characteristics Psychosocial Climate of Classroom (PsCC) student’s Mathematical Academic Engagement
