2Preparation of thalidomide nano-flakes by supercritical antisolvent with enhanced mass transfer显示文摘Thalidomide treats multiple myeloma and protracts life-span of patient, but its bioavailability is limited as it is poorly water soluble. Thalidomide nano-flakes are produced to improve the drug dissolution rate. Two nanoflake production methods are utilized for a comparative study:a supercritical antisolvent (SAS) method and a supercritical antisolvent with enhanced mass transfer (SAS-EM). SAS-EM utilizes ultrasonication to improve dispersion upon injection within the supercritical carbon dioxide. Comparative study of SAS and SAS-EM thalidomide confirmed that the application of ultrasonication improved the micro/nano particles produced by SAS. The effects of ultrasound power on the formation of thalidomide particles are examined. The particle size and morphology were characterized by SEM. The thalidomide nano-flakes produced by SAS-EM were smaller than the particles produced by SAS. Dissolution rates of the produced particles, evaluated by HPLC, demonstrated an increase in the thalidomide dissolution rate for the SAS-EM produced particles. The polymorphs and crystallinity of thalidomide particles (flakes) were observed by FTIR and XRD. In this research, the supercritical processing significantly modified the crystal formation of thalidomide from an original state of a β-polymorph to the amorphous state β-polymorph after supercritical processing.HeyangJin Melinda Hemingway Ram B.

3Intercrop movement of convergent lady beetle, Hippodamia convergens (Coleoptera: Coccinellidae), between adjacent cotton and alfalfa显示文摘2 年的研究被进行描绘会聚的女士甲壳虫的 intercrop 运动, Hippodamia convergens Guerin-Meneville (翘目:Coccinellidae ) 在邻近的棉花和苜蓿之间。一个双标记蛋白质的方法被用来在每庄稼估计女士甲壳虫的 intercrop 运动。收集的 In turns 地在每庄稼的女士甲壳虫是由蛋白质的 assayed 确定的特定的 ELISA 在庄稼之间的甲壳虫的运动。结果显示会聚的女士甲壳虫的一个高百分比在棉花抓住了(46% 在 2008;56% 在 2009 ) 并且苜蓿(46% 在 2008;71% 在 2009 ) 包含了一个蛋白质标记,因此显示那个会聚的女士甲壳虫运动在邻近的庄稼之间大部分是双向的。尽管在一个低得多的比例,女士甲壳虫也从棉花显示出单向性的运动到苜蓿(5% 在 2008 和 6% 在 2009 ) 并且从苜蓿到棉花(9% 在 2008 和 14% 在 2009 ) 。甲壳虫展出的季节长的双向运动在学习的两年期间比棉花在苜蓿是显著地更高的。女士甲壳虫的全部的流入(双向、单向性联合) 在棉花与那相比在苜蓿是显著地更高的两年。当会聚的女士甲壳虫在邻近的棉花和苜蓿之间移动了时,他们是当棉花不是 flowering 时或当苜蓿为猎物提供了更多的机会时,吸引到苜蓿的更多。这研究提供很需要的信息在上杂种应该在利用保存的棉花便于综合害虫管理决定的会聚的女士甲壳虫的运动生物控制。Anup Bastola Megha N.

4Effects of rainwater harvesting on herbage diversity and productivity in degraded Aravalli hills in western India显示文摘Over-exploitation and rural growth have severely damaged native vegetations of Aravalli hills in Rajasthan, India. This study was conducted to evaluate the effects of different restoration practices (i.e., rainwater harvesting (RWH) and planting of tree seedlings) on improve- ment in soil water and nutrients and growth and biomass of herbaceous vegetation. Contour trench (CT), Gradonie (G), Box trench (BT), V-ditch (VD) and a control were imposed on 75 plots (each of 700 m 2 ) in natural slope gradient defined as <10%, 10% 20% and >20% slopes in 2005. Each plot had three micro-sites of 1-m 2 at up (USP), middle (MSP) and lower (LSP) part of the plot for observation in 2008. The existed gradient (due to soil texture and topographic features) of soil pH, EC, SOC, NH 4 - N, NO 3 -N and PO 4 -P in June 2005 between >20% to <10% slopes were decreased in 2008 after applying RWH techniques. Such improvement in soil status promoted vegetation growth and biomass in higher slope gra- dients. Soil water, species diversity and herbage biomass increased from USP to LSP, and RWH techniques had positive role in improving SOC, nutrients, vegetation population, evenness and growth at MSP. Despite of lowest SWC, regular rain and greater soil water usage enhanced green and dry herbage biomasses in 10% 20% and >20% slopes, compared with <10% slope. The highest diversity in CT treatment was related to herbage biomass, which was enhanced further by highest concentrations of SOC and PO 4 -P. Further, CT treatment was found to be the best treat- ment in minimizing biomass variance in different slopes. Conclusively, soil texture and topographic features controlled soil water and nutrients availability. Rainwater harvesting techniques increased soil water storage and nutrient retention and also enhanced vegetation status and biomass by minimizing the effects of hillslopes. Thus depending upon the site conditions, suitable RWH technique could be adopted to increase herb- age biomass while rehabilitating the degraded hills.G. Singh G.R. Choadhary B. Ram N.K.
