| 1 | A Review on Pharmacological and Analytical Aspects of Diosmetin:A Concise Report显示文摘Plants have been used as a source for food material and natural remedies for the treatment of vast range of diseases.Nature provides us remedies for the treatment of various types of disorders ranging from simple ailments to complicated diseases.Plants are known to possess different pharmacological activities due to the presence of various phytoconstituents.Flavonoids are one of the main active phytoconstituents found in fruits,vegetables,wines,tea and cocoa.Flavonoids exhibit various pharmacological activities such as antioxidant,anti-inflammatory,anti-allergic,antibacterial,oestrogenic,cytotoxic antitumoural,hepatoprotective,antithrombotic and antiviral activity.Diosmetin(3',5,7-trihydroxy-4'-methoxyflavone),the aglycone part of the flavonoid glycosides diosmin occurs naturally in citrus fruit.Although it is found in herbal medicines and plays an important role in the treatment of various ailments,only limited scientific researches have been conducted.The aim of this review is to collect all available scientific literature published on diosmetin and combine it into this paper.This review contains an overview of pharmacological activities,isolation techniques and analytical techniques for diosmetin.Thus,valuable information provided in the present review will help researchers in developing alternative methods for the treatment of diseases from diosmetin. | Kanika Patel Manoj Gadewar Vijay Tahilyani Dinesh Kumar Patel | 2013 | Chinese Journal of Integrative Medicine2013，19，10： | 11 |
| 2 | Removal efficiency of fluoride by novel Mg-Cr-Cl layered double hydroxide by batch process from water显示文摘The fluoride ion removal from aqueous solution using synthesized Mg-Cr-Cl layered double hydroxide has been reported.Mg-Cr-Cl was characterized by X-ray powder diffraction,Fourier-transform infrared,thermo-gravimetric analysis,differential thermal analysis,and scanning electron microscope.Adsorption experiments were carried out in batch mode as a function of adsorption dosages,contact time,pH,and initial fluoride concentration to get optimum adsorption capacity.The adsorption kinetic study showed that the adsorption process followed first order kinetics.The fluoride removal was 88.5% and 77.4% at pH 7 with an adsorbent dose of 0.6 g/100 mL solution and initial fluoride concentration of 10 mg/L and 100 mg/L,respectively.The equilibrium was established at 40 min.Adsorption experiment data were fitted well with Langmuir isotherm with R 2 = 0.9924.Thermodynamic constants were also measured and concluded that the adsorption process was spontaneous and endothermic in nature.The removal percentage decreased slowly with increasing pH.This process is suitable for industrial effluents.The regeneration of the material is not possible. | Sandip Mandal Swagatika Tripathy Tapswani Padhi Manoj Kumar Sahu Raj Kishore Patel | 2013 | Journal of Environmental Sciences2013，25，5： | 7 |
| 3 | 膝关节Rosenberg位片上影像学分级与内侧开放楔形胫骨高位截骨术术后临床疗效的关系探讨显示文摘目的探讨与内侧开放楔形胫骨高位截骨术(open-wedge high-tibialosteotomy,OWHTO)术后临床疗效最密切相关的影像学分级方法,并找出与OWHTO预后相关的有利和不利因素。方法分析79例膝骨关节炎伴固有胫骨内翻畸形的患者,均接受OWHTO治疗。根据改良关节镜下Outerbridge分级以及影像学Kellgren-Lawrence(K-L)分级进行骨关节炎严重程度评估,影像学检查包括站立前后位(anteroposterior,AP)及屈曲45°后前(posteroanterior,PA)负重位(Rosenberg位)。临床疗效采用牛津膝关节评分(Oxford knee score,OKS)进行评估,包括术前和术后2年的随访。采用多元回归分析相关数据。结果随访2年,OKS评分均值由(20±4)分提高到(39±5)分(P<0.001)。平均机械胫股角由内翻的(6.9±3.4)°变为外翻的(2.7±2.8)°,胫骨近端内侧角(medial proximal tibial angle,MPTA)由(85.6±2.4)°变为(92.9±3.7)°(P<0.001)。术前膝关节站立前后位上K-L分级为(2.4±0.9)分,Rosenberg位上K-L分级为(2.8±0.9)分(P=0.003),关节镜下改良Outerbridge骨关节炎分级为(3.4±0.7)分。在多元回归分析中,Rosenberg位下K-L分级(P=0.01)、术后MPTA值(P=0.01)与术后2年随访的OKS评分呈显著负相关(P=0.01)。结论采用三种不同的骨关节炎分级方案(分别是改良关节镜下Outerbridge分级、站立前后位的K-L分级、Rosenberg位的K-L分级)来确定HTO手术指证,其中基于Rosenberg位的K-L分级与OWHTO术后OKS评分呈显著负相关,这与Rosenberg位下股骨髁与胫骨髁距离最近有关。说明基于Rosenberg位的K-L分级对HTO手术指证评估以及对晚期膝骨关节炎患者临床疗效的评估具有重要意义。 | Kyung Wook Nha Seung Min Oh Yoon Won Ha Manoj Kumar Patel Ji Hyun Seo Byung Hoon Lee 黄景星(整理) 王浩浩(整理) 张民(整理) | 2019 | 实用骨科杂志2019，25，10： | 4 |

| 5 | A Heuristic Algorithm for Core Selection in Multicast Routing显示文摘With the development of network multimedia technology, more and more real-time multimedia applications need to transmit information using multicast. The basis of multicast data transmission is to construct a multicast tree. The main problem concerning the construction of a shared multicast tree is selection of a root of the shared tree or the core point. In this paper, we propose a heuristic algorithm for core selection in multicast routing. The proposed algorithm selects core point by considering both delay and inter-destination delay variation. The simulation results show that the proposed algorithm performs better than the existing algorithms in terms of delay variation subject to the end-to-end delay bound. The mathematical time complexity and the execution time of the proposed algorithm are comparable to those of the existing algorithms. | Manas Ranjan Kabat Manoj Kumar Patel Chita Ranjan Tripathy | 2011 | Journal of Computer Science & Technology2011，26，6： | 0 |
| 6 | Experimental study on spraying performance of biological pesticides in aerial rotary cage nozzle显示文摘Aviation spraying is one of the most important methods for the treatment of forestry pests and diseases,which has a high operation efficiency and effectiveness.The combination of aviation spray and biological pesticides to reduce the impact of pesticide spray on environment has become an important development in the direction of agricultural aviation.In order to explore the effects of aviation spray parameters on particle size distribution and activity retention of biological pesticide droplets,a system of droplets size test and an activity retention rate test system of biological pesticides were constructed.The related experiments were conducted by changing the structural parameters of the rotary cage nozzle(the diameter of nozzle)and the technical parameters of the operation(rotary speed and flow rate).The results showed that the average relative width S of the droplets of the rotary cage nozzle was close to 1,and the droplet distribution was uniform.The influence factors on the particle size distribution of biological pesticide droplets were rotary speed,nozzle diameter,medium and flow rate in descending order.The rotary speed,nozzle diameter,and medium had a significant influence on droplet size distribution.The average activity retention rate of Bacillus thuringiensis was 88.83%,and the germination rate of Beauveria bassiana was 89.80%.The rotary speed had a significant effect on the activity retention rate of bacterial and fungal biological pesticides,and it was negatively correlated.The rotary speed was between 3000-5000 r/min,and the activity retention rate was higher.The research results can provide guidance for spraying biological pesticides in aerial plant protection operations with rotary cage nozzle. | Yu Ru Yangyang Liu Rongjia Qu Manoj Kumar Patel | 2020 | International Journal of Agricultural and Biological Engineering2020，13，6： | 0 |
| 7 | Improvement of Plasma Performance with Lithium Wall Conditioning in Aditya Tokamak显示文摘Lithiumization of the vacuum vessel wall of the Aditya tokamak using a lithium rod exposed to glow discharge cleaning plasma has been done to understand its effect on plasma performance. After the Li-coating, an increment of ~100 eV in plasma electron temperature has been observed in most of the discharges compared to discharges without Li coating, and the shot reproducibility is considerably improved. Detailed studies of impurity behaviour and hydrogen recycling are made in the Li coated discharges by observing spectral lines of hydrogen, carbon, and oxygen in the visible region using optical fiber, an interference filter, and PMT based systems. A large reduction in O I signal (up to ~ 40% to 50%) and a 20% to 30% decrease of H α signal indicate significant reduction of wall recycling. Furthermore, VUV emissions from O V and Fe XV monitored by a grazing incidence monochromator also show the reduction. Lower Fe XV emission indicates the declined impurity penetration to the core plasma in the Li coated discharges. Significant increase of the particle and energy confinement times and the reduction of Z eff of the plasma certainly indicate the improved plasma parameters in the Aditya tokamak after lithium wall conditioning. | M.
