In this paper the data for dailyconfirmed new casesconcerning the rise and fall of the Covid-19 (aka, coronavirus) pandemic infection in India for the nine month period starting from the first March 2020 has been subjected to a non linear least square fitting analysis using Gaussian, Skewed-Gaussian, Moffat, andVoigt model functions.The fitting parameters determined by the Python software package LMFIT are then used to compare the predicted remission times of Covid-19pandemic during 2021. It is found that while the Gaussian, Skewed-Gaussian and Moffat models predictlowlevels byabout March/April 2021; Voigt and other models predict longertimes to reach samelow endemic levels.
在本文中,使用高斯、偏高斯、莫法特和voigt模型函数,对从2020年3月1日开始的9个月期间,与印度Covid-19(又名冠状病毒)大流行感染的上升和下降有关的每日确诊新病例数据进行了非线性最小二乘拟合分析。然后使用Python软件包LMFIT确定的拟合参数对2021年covid -19大流行的预测缓解时间进行比较。研究发现,高斯、偏高斯和莫法特模型预测的水平大约在2021年3月/ 4月;Voigt和其他模型预测,达到同样的流行水平需要更长的时间。

A simple, highly efficient and environmentally friendly method has been developed for the synthesis of 2-(1,3-diphenyl-1H-pyrazol-4-yl)-1H-benzo[d]imidazole by using  Gadolinium(III) trifluoromethanesulfonate catalyst and ethanol reflux reaction conditions  By using this method. 12 new 2-(1,3-diphenyl-1H-pyrazol-4-yl)-1H-benzo[d]imidazole derivatives were synthesized under optimized reactions conditions. All these new products structures are confirmed by spectral analysis. By this method, we achieved imidazole derivatives with more operational simplicity, short reaction time and good yields (up to 85%).

Properties, behaviors, and applications of soft materials depend decisively on the characteristics of their surfaces. Physical features and chemical functionality of the soft surfaces control their interactions with the surroundings thereby deciding their responses to various physical and chemical phenomena. A gradient of such surface features i.e, a gradual change in a chemical or physical characteristic across a surface will result in a gradual change in the response of the surface to its surroundings in the same direction. Chemical as well as physical (morphological) gradients on soft surface enable useful properties pertinent to a variety of fields such as microfluidics, surface coatings, sensing, optics, and biology. Numerous methods have been used for the preparation of chemical as well as morphological gradients. Practical applications of soft surface gradients require stable large-scale surfaces with precisely controlled directionality and resolution of the gradients. Wettability gradients are one of the prominent classes of gradients created on soft surfaces. These gradients are constituted by gradual increase or decrease of hydrophobicity/hydrophilicity across a surface. One-dimensional (1D) as well as two-dimensional (2D) wettability gradients are fabricated with different patterns. This short review will summarize the advancements in the preparation, properties, and applications of wettability gradients on soft surfaces. Qualitative description of the fabrication processes, properties, and practical applications of the gradients are included along with our comments about the future prospects of these systems. 
软质材料的性质、行为和应用完全取决于其表面的特性。软表面的物理特性和化学功能控制着它们与周围环境的相互作用,从而决定了它们对各种物理和化学现象的反应。这种表面特征的梯度,即表面上化学或物理特性的逐渐变化,将导致表面对其周围环境在同一方向上的响应逐渐变化。软表面上的化学和物理(形态)梯度使得与微流体、表面涂层、传感、光学和生物学等各种领域相关的有用特性成为可能。许多方法已被用于制备化学和形态梯度。软表面梯度的实际应用需要稳定的大尺度表面,并精确控制梯度的方向性和分辨率。润湿性梯度是在柔软表面上产生的突出梯度之一。这些梯度是由表面上疏水性/亲水性的逐渐增加或减少构成的。一维(1D)和二维(2D)润湿性梯度具有不同的模式。本文将对软性表面润湿性梯度材料的制备、性能和应用等方面的研究进展进行综述。定性描述的制造过程,性质,和实际应用的梯度包括随着我们对这些系统的未来前景的评论。

India is a country where traditional medicines play a huge role in primary health care. Ayurveda, Siddha, Unani are some of the well-known traditional practices used for centuries and these traditional systems are highly dependent on medicinal plants. India is a rich source of these medicinal plants. The Western Ghats is known for its rich diversity, richness, and presence of endemic species. Menispermaceae family consists of more than 400 species; all are reported to have high medicinal values. Different classes of alkaloids present may be the major reason for these biological potentials, which are of great interest for various research groups. Benzylisoquinoline alkaloids, protoberberine alkaloids, aporphine alkaloids, etc are some examples for the alkaloids present in the Menispermaceae family. This review deals with the phytochemistry and pharmacological study of the Menispermaceae family and the action of these plants against various infectious diseases, described in Ayurveda.

Is Reduced Planck’s Constant- An Outcome of Electroweak Gravity? 简化普朗克常数是电弱引力的结果吗?

When mass of any elementary is extremely small/negligible compared to macroscopic bodies, highly curved microscopic space-time can be addressed with large gravitational constants and magnitude of elementary gravitational constant seems to increase with decreasing mass and increasing interaction range. Following the notion of string theory, compactification of 6 un-observable spatial dimensions might be playing a key role in hiding the large magnitudes of the three atomic gravitational constants.  In this context, in our earlier publications, we proposed the existence of three large atomic gravitational constants assumed to be associated with electroweak, strong and electromagnetic interactions. Proceeding further, 1) Electroweak field seems to be operated by a primordial massive fermion of rest energy 585 GeV and can be considered as the zygote of all elementary particles and galactic dark matter; 2) H-bar seems to be a compactified outcome of unified electroweak gravity.
当任何元素的质量与宏观物体相比非常小或可以忽略时,可以用大的引力常数来处理高度弯曲的微观时空,并且基本引力常数的大小似乎随着质量的减小和相互作用范围的增加而增加。根据弦理论的概念,6个不可观测空间维度的紧化可能在隐藏三个原子引力常数的巨大数值方面发挥了关键作用。在这种情况下,在我们早期的出版物中,我们提出存在三个大的原子引力常数,假设它们与电弱、强和电磁相互作用有关。进一步说,1)电弱场似乎是由一个静止能量为585 GeV的原始大质量费米子操作的,可以认为是所有基本粒子和星系暗物质的合子;2) h棒似乎是统一电弱引力的紧化结果。

Adsorption is considered to be one of the most promising techniques for wastewater treatment over the last decades. The economic crisis of the 2000s led researchers to turn their interest in adsorbent materials with lower cost. The study was conducted to treat the Textile, dye and printing industry effluent using naturally occurring biological adsorbents (Areaca catechu, Moringa pterygosperma, Quercus infectoria and Tamarindus indica). The treatment was carried out on various concentrations (25%, 50% 75% and 100%) of dye effluent. Highest removal of pollutant was observed at lower effluent concentrations (25% and 50%) as compared to higher effluent concentrations (75 % and 100%). The addition of biological adsorbents has brought a significant reduction in various parameters of Textile, dye and printing industry effluent. The reduction in pollution load may be due to the coagulative / chelative property of Areaca catechu, Moringa pterygosperma, Quercus infectoria and Tamarindus indica can be used as low cost and safest biological adsorbents for removing toxic substances in Textile, dye and printing industry effluent.
吸附法被认为是近几十年来最有前途的污水处理技术之一。21世纪初的经济危机使研究人员将兴趣转向了成本较低的吸附材料。本研究采用天然生物吸附剂(槟榔、辣木、栎木和柽柳)处理纺织、染料和印染工业废水。对不同浓度的染料废水(25%、50%、75%和100%)进行处理。与较高的污水浓度(75%和100%)相比,在较低的污水浓度(25%和50%)下观察到的污染物去除率最高。生物吸附剂的加入使纺织、染料和印染工业废水的各项参数显著降低。儿茶、辣木、栓皮栎和柽柳具有一定的混凝/螯合特性,可作为低成本、最安全的生物吸附剂,用于去除纺织、染料和印染工业废水中的有毒物质。

Gymnema sylvestre (Madhunashini) is one of the most important medicinal plants used as a crude drug for its preventive and therapeutic properties. Among other constituents of Gymnema, gymnemic acid is a major component responsible for biological and pharmacological actions. The present study deals with the influence of different media strength and initial medium pH on the growth of hairy roots and gymnemic acid production from Gymnema sylvestre. Higher strength of the media (1.5X) favoured the biomass production (114.64 g/L FW and 12.63 g/L DW) and gymnemic acid content (11.7 mg/g DW) in the tested range of 0.25, 0.50, 0.75, 1.0, 1.5 and 2.0 X strength. Among the different hydrogen ion concentration (pH) of 4.0, 4.5, 5.0, 5.5, 5.8, 6.0 and 6.5, initial medium pH of 6.0 favoured the biomass production (102.41 g/L FW and 11.52 g/L DW) and medium pH of 5.8 favoured the gymnemic acid production (11.30 mg/g DW).
匙羹藤(Gymnema sylvestre, Madhunashini)是一种重要的药用植物,具有预防和治疗作用。在匙羹藤的其他成分中,匙羹藤酸是负责生物和药理作用的主要成分。本文研究了不同培养基强度和初始培养基pH对裸子藤毛状根生长和裸子藤酸产量的影响。在0.25、0.50、0.75、1.0、1.5和2.0倍强度范围内,培养基强度越高(1.5倍),生物量产量(114.64 g/L FW和12.63 g/L DW)和裸子酸含量(11.7 mg/g DW)越高。在不同氢离子浓度(pH)为4.0、4.5、5.0、5.5、5.8、6.0和6.5时,初始培养基pH为6.0时有利于产生生物量(102.41 g/L FW和11.52 g/L DW),初始培养基pH为5.8时有利于产生裸子酸(11.30 mg/g DW)。

The study was conducted in Meenangadi panchayat of Wayanad, Kerala. Agriculture was primary occupation for majority of the respondents (44 percent). 38 percentage of the respondents were utilising the facilities provided by the animal husbandry department of the state. According to the perception of 72 percent of the respondents, the most important constraint in dairy farming was the non-availability of fodder followed by responses that indicated the next deterrent to be the high cost of cattle feed (60 percent). A total of fourteen clean milking practices were analysed and adoption of milking practices were calculated by using adoption index. Majority of the respondents were found to be medium adopters.
这项研究是在喀拉拉邦瓦亚纳德的Meenangadi panchayat进行的。农业是大多数受访者(44%)的主要职业。38%的受访者正在使用国家畜牧部门提供的设施。72%的受访者认为,奶牛养殖中最重要的制约因素是无法获得饲料,其次是牛饲料的高成本(60%)。对14种清洁挤奶方式进行了分析,并采用采用率指数计算了挤奶方式的采用率。大多数受访者被发现是中等采用者。
