The present study was conducted to review the phytochemical composition, as well as nutritional and pharmacological values of Allium cepa L. (Onion). Onion is cultivated all over the world.  Onion bulbs are composed of polysaccharides such as peptides, fructans, flavonoids (mostly quercetin), saccharose and organosulfur compounds having salutary effects on human health. Onion is beneficial for human health since it has a high nutritional value. The nutritional constituents of an onion bulb are crude oil, vitamin E, sodium, potassium, and zinc. The onion bulb has the potential to reduce diseases such as stomach cancer, osteoporosis, and brain cancer in human beings. Additionally, onion is antidiabetic, anti-inflammatory, anti-scar, antispasmodic, antiseptic, anti-genotoxic, anti-mutagenic, diuretic, anti-parasitic, antimicrobial, antipyretic, and analgesic.

For the expected ruin time of the classic three-player symmetric game, Sandell derived a general formula by introducing an appropriate martingale and stopping time. For the case of asymmetric game, the martingale approach is not valid to determine the ruin time. In general, the ruin probabilities for both cases, i.e. symmetric and asymmetric game and expected ruin time for asymmetric game are still awaiting to be solved for this game. The current work is also about three-player gambler’s ruin problem with some extensions as well. We provide expressions for the ruin time with (without) ties when all the players have equal (unequal) initial fortunes. Finally, the validity of asymmetric game is also tested through a Monte Carlo simulation study.
对于经典的三人对称博弈的预期毁灭时间,Sandell通过引入适当的鞅和停止时间推导出了一般公式。对于非对称博弈,鞅法不能确定破产时间。一般情况下,对于该博弈,对称和非对称两种情况下的破产概率以及非对称博弈的预期破产时间仍有待求解。目前的工作也是关于三个玩家赌徒的破产问题,以及一些扩展。当所有玩家初始财富相等(不相等)时,我们给出了有(无)平局的破产时间表达式。最后,通过蒙特卡罗仿真研究验证了非对称对策的有效性。

Abid Hussain, Muhammad Hanif, Moazzam Naseer
For calculating the expected ruin time of the classic three-player symmetric game, Sandell derived a general formula by introducing an appropriate martingale and stopping time. However, the martingale approach is not appropriate to determine the ruin time of asymmetric game. In general, ruin probabilities in both cases, that is, symmetric and asymmetric games as well as the expected ruin time for the asymmetric games are still need to be calculated. The current work is also about three-player gambler’s ruin problem with some extensions. We provide expressions for the ruin time with or without ties when all the players have equal or unequal initial fortunes. Finally, the validity of the asymmetric game is also tested through a Monte Carlo simulation study. Copyright (c) The Authors

The present study aims to determine the quality parameters of drinking water of rural Tharparkar i.e., Diplo area. The quality parameters examined in water samples were pH, TDS, and EC. A total of 20 samples were collected randomly from different sources of drinking water (dug well and hand pump water) from Diplo Sub District of Tharparkar. Results showed that water samples of hand pump source have elevated quality parameters (i.e., pH range was 5.7-6.0 and TDS range was 1579-2120mg/L) as compared to well water samples (i.e., pH range was 5.09-6.60 and TDS range was 497-1182mg/L). Therefore, it is concluded that as per guidelines of WHO and EPA, water from well sources is somehow good to ensure well-being of human population residing in the area. While water from the hand pump source is loaded with high TDS and EC (greater than WHO limit). The aforementioned parameter is highly linked with EC as well as pH. It is directly proportional to the conductivity and inversely proportional to the pH. Further, studies need to be conducted in this measure to evaluate quality of drinking water in rural areas of Sindh province.  
本研究旨在确定农村饮用水的质量参数,即Diplo地区。检测水样的质量参数为pH、TDS和EC。从Tharparkar Diplo街道的不同饮用水来源(挖井和手泵水)随机收集了总共20个样本。结果表明,手泵源水样的水质参数(pH范围为5.7 ~ 6.0,TDS范围为1579 ~ 2120mg/L)高于井水(pH范围为5.09 ~ 6.60,TDS范围为497 ~ 1182mg/L)。因此,根据世卫组织和环境保护署的准则得出的结论是,井水在某种程度上对确保居住在该地区的人口的福祉是有益的。而来自手泵源的水则含有高TDS和EC(高于世卫组织限值)。上述参数与EC和ph高度相关。它与电导率成正比,与ph成反比。进一步,需要对信德省农村地区的饮用水质量进行研究。

The present study aimed to determine the quality parameters of underground drinking water found in Diplo, a sub-district of Tharparkar. The quality parameters examined in the water samples were pH (acidity), total dissolved solids (TDS), and electrical conductivity (EC). A total of 20 samples were randomly collected from different sources of drinking water, namely dug well and hand pump, from the study area. The results showed that the quality parameters of water samples taken from the hand pump were not within the appropriate range (pH range was 5.7-6.0 and TDS range was 1579-2120 mg/L), while those of well water samples were within range (pH range was 5.09-6.60 and TDS range was 497-1182 mg/L). Therefore, it was concluded that water from the well sources was safe for consumption as per the guidelines set by WHO and EPA and could be used for drinking purposes. The findings revealed that water from the hand pump sources had high TDS and EC (greater than WHO limit), which pose several health risks. It was noted that TDS is directly proportional to electrical conductivity and inversely proportional to the pH level of water. Further, it was recommended that future studies need to be conducted at regular intervals to evaluate the quality of drinking water in rural areas of Sindh province, so that authorities can promptly provide solutions to such issues.

本研究旨在确定在Tharparkar的Diplo街道发现的地下饮用水的质量参数。检测水样的质量参数为pH(酸度)、总溶解固体(TDS)和电导率(EC)。随机抽取研究区不同饮用水源(挖井和手泵)20个样本。结果表明,手泵水样的水质参数不在适宜范围内(pH值为5.7 ~ 6.0,TDS值为1579 ~ 2120 mg/L),井水水质参数在适宜范围内(pH值为5.09 ~ 6.60,TDS值为497 ~ 1182 mg/L)。因此,得出的结论是,根据卫生组织和环境保护局制定的准则,井水可以安全饮用,并可用于饮用。调查结果显示,来自手泵源的水具有高TDS和EC(高于世卫组织限值),这构成了若干健康风险。注意到TDS与电导率成正比,与水的pH值成反比。此外,还建议今后需要定期进行研究,以评估信德省农村地区的饮用水质量,以便当局能够及时提供解决这些问题的办法。版权(c)作者

In external beam radiation therapy, electron and photon beams have extraordinary characteristics in the treatment of cancer. The electron and photon beam characteristic are essential to study before calibration of machine. This study focused on the dosimetric characteristics of different energies of electron beams for different field size. The basic objective of this work is, to calculate dosimetric parameters and characteristics of electron beam, specially depth dose characteristics along central axis. In this work, 6 MeV, 9 MeV, 12 MeV, 15 MeV and 18 MeV of electron beam and 6 MV and 15 MV of photon beam with different field size is used. Characteristics of depth dose of electron and photon beam in water have analyzed to provide better quality of radiation therapy treatment planning. The different beam characteristics are due to different interactions that occurs between electron beams giving them a definite range whereas photon beams are attenuated leading to dose deposition and much larger range with no definite end. Depth dose characteristics of electron and photon beams do not show same characteristics as interaction of beam with matter depends on the quality of beam. Attenuation and penetration factors change with changing dosimetric parameters. Complete analysis of dosimetric characteristics of electron and photon beam help to choose more accurate beam for the treatment of cancer. This work will help to increase accuracy in treatment of cancer with radiotherapy.
在外束放射治疗中,电子束和光子束在治疗癌症方面具有非凡的特点。在仪器标定前,电子束和光子束的特性研究是必不可少的。本文研究了不同场强下不同能量电子束的剂量学特性。本工作的基本目的是计算电子束的剂量学参数和特性,特别是沿中心轴的深度剂量特性。本文采用了6 MeV、9 MeV、12 MeV、15 MeV和18 MeV的电子束,以及6 MV和15 MV的不同场大小的光子束。分析了水中电子束和光子束的深度剂量特性,为提高放射治疗方案的质量提供依据。不同的光束特性是由于电子束之间发生不同的相互作用,使它们具有一定的范围,而光子束被衰减导致剂量沉积和更大的范围,没有确定的结束。电子束和光子束的深度剂量特性不表现出与物质相互作用相同的特性,这取决于光束的质量。衰减和穿透因子随剂量学参数的变化而变化。对电子束和光子束的剂量学特性进行全面分析,有助于选择更精确的治疗光束。这项工作将有助于提高放疗治疗癌症的准确性。

A series of three donor molecules (DPP-B, DPP-N and DPP-P) based on diketopyrrolopyrrole (DPP) sharing the similar backbone of D-π-A-π-D have been investigated. In these molecules, substituents such as pyrene, naphthalene and benzene act as the electron donating end groups, DPP as the central core unit and thiophene has been used as a bridge between donor and acceptor fragments. Theoretical calculations have been carried out with the help of density functional theory (DFT) and time-dependent functional theory (TD-DFT). For the optimization of geometry of investigated molecules, DFT functional B3LYP/6-31g(d) has been used and TD-B3LYP/6-31g(d) has been used to obtain the best results of calculations inexcited state. DPP-P has been considered a suitable donor molecule among all investigated molecules as it manifests the suitable value of Eg of 2.24 eV and showed the stronger absorption λmaxof 611 nm. Hence, this study reveals that investigated donor molecules are suitable for high performance organic solar cell devices

This research work is related to unsteady movement of second-grade fluid over an infinite plate. The governing equations for flow are developed through constitutive relations. Then classical model extended to fractional order model with power law fractional differential operator. The Laplace transform (LT) technique is applied to find the analytical results and stated as series satisfy the boundary conditions. To see physical significance of flow parameters some graphs are displayed. Recent results from the existing literature are recovered to validate.   Copyright(c) The Authors

The incidence of Diabetes Mellitus (DM) type I and type II is very high all over the world. Excessive glucose levels and failure of one’s body to produce or manage glucose, trigger diabetes. Glucose is known to be responsive to NIH3T3 cells as it alters the expression of a range of genes associated with inflammation and apoptosis. In this study, the toxic effect of glucose was evaluated on NIH3T3 fibroblasts. Cells (NIH3T3) were cultured in media (DMEM), supplemented with 10% FBS and 1% Penicillin-Streptomycin. MTT assay was performed to check the toxic effect of glucose. NIH3T3 cells were treated with high glucose (30mM) for 24 hours. Trizol was used to extract the RNA followed by PCR reactions for gene expression analysis. Glucose treatment for 24 hours, modulated the expression of BCL-2 and BAX genes. The expression of BCL-2 was reduced while a significant increase was noticed in the expression BAX gene. Our results illustrated that glucose has some toxic effects on NIH3T3 cells. Glucose induces apoptosis by upregulating BAX and down-regulating BCL-2 expressions.
1型和2型糖尿病的发病率在世界范围内都很高。葡萄糖水平过高,身体不能产生或控制葡萄糖,会引发糖尿病。已知葡萄糖对NIH3T3细胞有反应,因为它改变了一系列与炎症和凋亡相关的基因的表达。本研究评估了葡萄糖对NIH3T3成纤维细胞的毒性作用。细胞(NIH3T3)在培养基(DMEM)中培养,培养基中添加10%胎牛血清和1%青霉素-链霉素。采用MTT法检测葡萄糖的毒性作用。NIH3T3细胞用高糖(30mM)处理24小时。用Trizol提取RNA, PCR反应进行基因表达分析。葡萄糖处理24小时后,BCL-2和BAX基因的表达发生变化。BCL-2表达降低,BAX基因表达显著升高。我们的研究结果表明,葡萄糖对NIH3T3细胞有一定的毒性作用。葡萄糖通过上调BAX和下调BCL-2表达诱导细胞凋亡。
