The rapid progress on the Cu–Sn–S (Cu2SnS3, Cu3SnS4, and Cu4SnS4) solar cells has opened a new avenueto generate the electrical energy at ultra-low-cost. Therefore, the progress in the deposition of Cu2SnS3,Cu3SnS4, and Cu4SnS4 thinfilms by various chemical and physical methods is reviewed comprehensively. This article briefly describes (i) the phase diagrams of Cu–Sn–S, (ii) the bulk properties of Cu2SnS3,Cu3SnS4, and Cu4SnS4, (iii) the effect of deposition conditions on the phase formation, (iv) the physicalproperties of Cu2SnS3, Cu3SnS4, and Cu4SnS4 thinfilms, and (v) the photovoltaic performance of Cu2SnS3,Cu3SnS4, and Cu4SnS4 solar cells.

Withania somnifera (ashwagandha) has been used traditionally as a remedy for insomnia and to enhance cognitive function. The effects of ashwagandha extract (AE, 35% withanolide glycosides, Shoden<SUP>Ⓡ</SUP>) on the expression levels of γ-aminobutyric acid (GABA)Aρ1 and histamine H3 receptors in Rattus norvegicus glioblastoma (C6) cell lines were studied using semiquantitative reverse transcriptase-polymerase chain reactions. The effects of AE on sleep onset and duration were studied in Swiss albino mice using the pentobarbital-induced sleep model. Furthermore, the effects on nonrapid eye movement (NREM) and rapid eye movement sleep patterns were studied in Wistar rats with electroencephalogram (EEG) to support the improvement in sleep quality. There was an increase in gene expression levels of GABAAρ1 receptor (1.38 and 1.94 folds) and histamine H3 (1.14 and 1.29 folds) receptors induced by AE at doses of 15 and 30 μg/mL compared to control. AE at doses of 10, 25, and 50 mg/kg body weight showed a significant decrease in time to sleep onset and increased total sleep duration in the pentobarbital-induced sleep model. At 50 mg/kg body weight dosage level, a 34% decrease (P<0.0001) in sleep onset time and 47% increase (P<0.0001) in sleep duration was observed. The EEG study showed significant improvement in alpha, beta, theta, delta, and gamma bands at doses of 10, 25, and 50 mg/kg body weight with delta waves showing increases of 30%, 46% (P<0.05), and 34%, respectively. The induction of sleep, GABA-mimetic action, NREM sleep, and the effects on slow-wave cycles support the calming property of AE in improving the quality of sleep.

The ethanol extract of the roots of Aerva persica (Burm f) Merrill (Amaranthaceae) was investigated to determine its antiulcer and in vivo antioxidant activities in albino Wistar rats. Ulcers were induced by ethanol and pylorus ligation. The extract was administered at the dose of 200 mg/kg orally, p.o. for 15 consecutive days. The ulcer index of the ethanol extract was found to be significantly reduced compared with control animals. The effect was also assessed by determining the free acidity, pepsin activity, total carbohydrate (TC), and protein content (PK) in control, standard, and test group animals. The in vivo antioxidant activity was evaluated by determining the reduced glutathione level (GSH)and malondialdehyde (MDA) level in the tissue homogenates. The results reveal the significant reduction in the level of malondialdehyde and the increase in the level of reduced glutathione in the rats that received the ethanolic extract. Furthermore, histopathological studies have shown that pretreatment with the ethanolic extract of the roots of A persica reduces (100%) ethanol- and pylorus ligation-induced hemorrhagic necrosis in rats.
Anti-spermatogenic Activity of Ethanol Extract of Dalbergia sissoo Roxb. Stem Bark
Neeru Vasudeva,Manisha Vats 사단법인약침학회 2011 Journal of Acupuncture & Meridian Studies Vol.4 No.2
The study was undertaken to evaluate the anti-spermatogenic efficacy of ethanol extract of stem bark of Dalbergia sissoo Roxb. For the in vitro study, semen samples were obtained from 15 healthy fertile men aged 25−35 years. Sperm motility was examined by the Sander-Cramer method. A dose-dependent and time-dependent effect of ethanol extract on sperm motility and sperm viability were observed. Various concentrations affected the motility of sperm. Ethanol extract at a concentration of 20 mg/mL caused complete immobilization within 3 minutes. Sperm viability and hypo-osmotic swelling was significantly reduced at this concentration. The in vivo studies were carried out on Swiss male albino mice. Ethanol extract at a dose of 200 mg/kg body weight resulted in a significant decrease (p < 0.001) in weight of the testis and epididymis. A significant decrease (p < 0.01) in sperm motility and sperm count in the epididymis were observed. Histological changes in the epididymis and testis were also investigated.

Generally the fluid flows within the centrifugal impeller passage as a decelerating flow with an adverse pressure gradient along the stream wise path. This flow tends to be in a state of instability with flow separation zones on the suction surface and on the front shroud. Hence several experimental attempts were earlier made to assess the efficacy of using boundary layer fences to trip the flow in the regions of separation and to make the flow align itself into stream wise direction so that the losses could be minimized and overall efficiency of the diffusion process in the fan could be increased. With the development of CFD, an extensive numerical whole field analysis of the effect of boundary layer fences in discrete regions of suspected separation points is possible. But it is found from the literature that there have been no significant attempts to use this tool to explore numerically the utility of the fences on the flow field. This paper attempts to explore the effect of boundary layer fences corresponding to various geometrical configurations on the impeller as well as on the diffuser. It is shown from the analysis that the fences located on the impellers near the trailing edge on pressure side and suction side improves the static pressure recovery across the fan. Fences provided at the radial mid-span on the pressure side of the diffuser vane and near the leading edge and trailing edge of the suction side of diffuser vanes also improve the static pressure recovery across the fan.
