1仙茅:对健康有众多益处的黑金(英文)显示文摘仙茅(石蒜科)是一种濒临灭绝的多年生草本植物,是印度本土药,作为强有力的适应原和春药在印度传统药物中占有重要位置。它也是多种印度传统药物处方的重要组成部分,被认为具有促进性欲、刺激免疫、保护肝脏、抗氧化、抗癌和治疗糖尿病等作用。已有报道,从仙茅中提取出多种化学成分,如植物黏胶,酚苷、皂苷和脂肪族化合物等。仙茅也是中医和日本汉方医学中各种草药处方的重要成分。本文对仙茅的多种生物活性和其不同化学成分的作用进行了综述。Nagendra Singh Chauhan Vikas Sharma Mayank Thakur Vinod Kumar Dixit 2010中西医结合学报2010,8,7:6
2Enhanced thermoelectric performance in p-type ZrCoSb based half-Heusler alloys employing nanostructuring and compositional modulation显示文摘ZrCoSb based half-Heusler(HH)alloys have been widely studied as a p-type thermoelectric(TE)material for power generation applications in the mid-temperature regime.However,their intrinsically high thermal conductivity has been found to be detrimental for the improvement in their thermoelectric figure-of-merit(ZT),which presently is far below unity.In the current work,a state-of-the-art ZT~1.1 at 873 K was realized in an optimized composition of nanostructured Zr1-xHfxCoSb_(0.9)Sn_(0.1) HH alloys by employing compositional modulation i.e.grain-by-grain compositional variations,which leads to a substantial increase in its power factor coupled with a concurrent decrease in its thermal conductivity.Significant reduction in the phonon mean-free-path is observed on Hf substitution,which is comparable to the average crystallite size(~25 nm),thus leading to a very low thermal conductivity of~2.2Wm^(-1)K^(-1) at 873 K,which is amongst the lowest reported in HH alloys.The TE device characteristics,estimated using cumulative temperature dependence model for quantitative evaluation of TE performance,yielded an output power density of~10 Wcm2 with a leg efficiency of~10%in the optimized composition of nanostructured Zr_(1-x)Hf_(x)CoSb_(0.9)Sn_(0.1) HH alloys,which is comparable to the reported efficiencies of other state-of-the-art TE materials.Nagendra S.Chauhan Sivaiah Bathula Avinash Vishwakarma Ruchi Bhardwaj Kishor Kumar Johari Bhasker Gahtori Ajay Dhar 2019Journal of Materiomics2019,5,1:3
3南欧派利吞草石油醚提取物对雄性大鼠性行为的影响(英文)显示文摘目的:检测南欧派利吞草石油醚提取物(petroleum ether extract,PEE)对雄性大鼠性行为的影响。方法:制备南欧派利吞草PEE。32只雄性Wistar大鼠分成对照组、睾酮组、低剂量PEE组和高剂量PEE组,每组8只。对照组大鼠灌胃花生油(溶剂对照),睾酮组大鼠肌肉注射0.5mg/kg睾酮,每周2次,低剂量和高剂量PEE组大鼠分别灌胃50和100mg/kgPEE,治疗持续28d。于治疗前,治疗第15天、第28天和治疗后第7天、第15天,检测大鼠体质量,治疗结束后,取4只大鼠性器官(睾丸、附睾、精囊、前列腺)称取质量,其余4只大鼠用于检测大鼠的性取向行为和性功能。结果:与对照组大鼠比较,PEE治疗28d可明显增加雄性大鼠的体质量和性器官质量,雄性大鼠易于接受雌性大鼠和对雌性大鼠趋向性增加,雄性大鼠性能力增加,表现为舔、嗅雌性大鼠肛门和生殖器,阴茎勃起指数增加,交配潜伏期缩短,交配频率增加。在PEE治疗结束后7和15d仍观察到以上行为和性指标的变化。结论:与睾酮不同的是,PEE治疗结束后7和15d仍可见明显治疗效果,提示南欧派利吞草能提高大鼠性潜能,并有延迟效应。Vikas Sharma Mayank Thakur Nagendra S.Chauhan Vinod Kumar Dixit 2010中西医结合学报2010,8,8:2

18Application of Fractional Order PID Controller for AGC Under Deregulated Environment显示文摘In this paper, a fractional order proportional integral derivative(FOPID) controller for multiarea automatic generation control(AGC) scheme has been designed. FOPID controller has five parameters and provides two additional degrees of flexibility in comparison to a proportional integral derivative(PID) controller. The optimal values of parameters of FOPID controller have been determined using Big Bang Big Crunch(BBBC) search algorithm. The designed controller regulates real power output of generators to achieve the best dynamic response of frequency and tie-line power on a load perturbation. The complete scheme for designing of the controllers has been developed and demonstrated on multiarea deregulated power system. The performance of the designed FOPID controllers has been compared with the optimally tuned PID controllers. It is observed from the results that the FOPID controller shows a considerable improvement in the performance as compared to the conventional PID controller.Nagendra Kumar Barjeev Tyagi Vishal Kumar 2018International Journal of Automation and computing2018,15,1:1
