堰塞湖泄洪（LLOF）现象在喜马拉雅山流域很常见，这是由于滑坡作用形成的湖泊溃决所致。根据绘制的Satluj和Spiti河沿岸的活动滑坡和古滑坡图，发现第四纪时期一些河流被围堵而且在某些位置还发生了决堤。本文记载了2000年和2005年期间，横跨喜马拉雅山脉的Satluj和paree Chu河沿岸的堰塞湖溃决引发的LLOF。Satiuj和paree Chu河都流经中国西藏地区，对印度Himachal pradesh的Kinnaur区的河道和基础设施均有影响。结果表明，这些LLOF造成的生命和财产损失与第四纪物质的处理以及与该区域内观察到的不同地貌带有直接关系。

Doxorubicin is associated with adverse effects on organs like liver. This study was done to find the effects of doxorubicin on liver of wistar albino rats. Sixty healthy wistar albino rats were taken for the study. The rats were randomly divided in to 4 groups （2 experimental groups; group AI and A2, and 2 control groups;group Bland B2 each containing 16 rats）. The experimental groups were given a single dose of doxorubicin i.e. 10 mg/kg body weight intraperitoneally and sacrificed after 7 days and 14 days for each group. Rats under control groups were given a single intraperitoneal dose of 2.5 ml/kg body weight normal saline and sacrificed with their respective experimental groups. A significant difference （p 〈 0.001） and （p = 0.005） in final body weight was observed among group A1 experimental and BI control rats, and among group A2 experimental and B2 control rats. As compared to group B2 control, group A2 experimental rats had significantly （p = 0.043） lower liver weight. Diameter ofhepatocyte （p 〈 0.001 for both groups） and nucleus （p=0.004 for group A1 and control BI, and p 〈 0.001 for group A2 and control B2） was significantly higher in experimental rats as compared to their respective controls. Cross-sections of the liver of both control groups had normal architecture. However, there was progressive destruction of liver architecture across the experimental groups. Doxorubicin causes the disruption of normal architecture of liver in rats. Thus care needs to be taken during doxorubicin chemotherapy to minimize effects on river.

A simple rectangular microstrip antenna on low dielectric constant substrate such as air for improved radiation beam performance is theoretically investigated. The conventional patch antenna fabricated on common substrates always produces quite broader E plane pattern compared to its H plane. In the present investigation, the same microstrip antenna is designed on air substrate with a view to develop an efficient feed for parabolic reflector antenna, which shows an excellent radiation pattern with symmetrical 3 dB beam widths at its both E and H plane. The present antenna compared to conventional structure to show its excellence in the beam performance is presented. The complete quantitative analysis to explore such radiation beam characteristics for both the structures (conventional and the present one) is also presented in this paper. An easy and handful relationship between the length of patch antenna and its fringing length for different types of substrate is established in the background of 3 dB beam widths. The proposed idea has been verified through a commercial software package for a patch operating in X band and a concrete physical insight into the phenomenon is developed.

A field experiment was conducted to study the growth and productivity of wheat as affected by row spacing and direction of sowing at Rampur, Chitwan, Nepal during the 2007-2008 wheat growing season. The experiment was carried out in 3-factors factorial randomized complete block design comprising two varieties (Gautam and BL-2800), three row spacings (15, 20 and25 cm) and two row directions of sowing (east-west and north-south). The effects of variety and row direction of sowing on grain yield were significant (p pacing treatment. BL-2800 variety produced higher grain yield (3.53 t·ha-1) as compared to Gautam (3.11 t·ha-1). Both wheat varieties yielded about 11% higher (p ompared to the eastwest sowing.

Glycerol is the main byproduct from the production of biodiesel by transesterification of vegetable oils, and approximately 10% of total biodiesel production volume corresponds to glycerol. The profitability of various chemical processes depends, in part, on the sale of byproducts, which enables a reduction in the production costs and consequently, in the product’s final price. Thus, it is necessary to look for alternatives to solve the problem of glycerol buildup, in order to avoid future environmental impacts and make biodiesel competitive in the growing market of biofuels. In this context, this study’s objective is the development of a low cost and environmental clean technology that allows the conversion of glycerin into a greater value product. In this paper, an economic evaluation of production hydrogen using Aqueous phase Reforming (ApR) was conducted. Firstly, we detailed the technical assumptions in the study. Reactions were performed in batch reformer of 10 liters of capacity, at the temperature of 250℃ and pressure of 38 atm. Finally, a sensitivity analysis was performed. The results from economic evaluation show that ApR of glycerol, using nickel catalysts supported on alumina or zirconium oxide, is a promising and competitive technology for hydrogen production.

Background and objective previous studies have demonstrated the anti-cancer effects of propolis. However, its use is limited because of its poor bioavailability. In the present study, the major objective was to improve propolis bioavailability using a nanosuspension formulation. The cytotoxic effect of propolis nanosuspension (pRO-NS) on the Ehrlich ascites carcinoma (EAC) in female Swiss albino mice was investigated in comparison to the free propolis. Materials and methods A propolis-loaded nanosuspension was formulated by applying solvent-antisolvent nano-precipitation technique. The prepared pRO-NS was characterized for average particle size, polydispersity index (pDI) and zeta potential. Also, the morphology of the nanosuspension particles was investigated using scanning electron microscopy (SEM). Moreover, pRO-NS cytotoxicity was tested using EAC bearing mice. The anticancer activity of pro-NS was assessed by studying tumor volume, life span, viable and non-viable cell count, antioxidant, biochemical estimations and proliferation of EAC cells. Results The results revealed that propolis nanoparticles were relatively spherical in shape with rough surface. The tumor bearing mice treated with pRO-NS showed increased life span and inhibited tumor growth and the proliferation of EAC cells in comparison to the free propolis (p Conclusions Our results indicate that pRO-NS has a strong inhibitory activity against growth of tumors in comparison to free propolis. The anti-tumor mechanism may be mediated by preventing oxidative damage, immune-stimulation and induction of apoptosis.

The bipolar theory of field-effect transistor is introduced to replace the 55-year-old classic unipolar theory invented by Shockley in 1952 in order to account for the characteristics observed in recent double-gate nanometer silicon MOS field-effect transistors. Two electron and two hole surface channels are simultaneously present in all channel current ranges. Output and transfer characteristics are computed over practical base and gate oxide thicknesses. The bipolar theory corroborates well with experimental data reported recently for FinFETs with metal/silicon and p/n junction source/drain contacts. Single-device realization of CMOS inverter and SRAM memory circuit functions are recognized.
