| 1 | Settling characteristics of ultrafine iron ore slimes显示文摘The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the settling study. It was observed that the original slurry exhibited a low settling velocity and a turbid supernatant during the settling process. Commercial flocculating agents with anionic, cationic, and nonionic characters were used to improve the settling behavior of suspensions, which were added into the slurry at different ranges of slurry pH values, respectively. The settling results show that the use of flocculants increase the settling rate by several times. Compared with the cationic and non-ionic flocculants, the anionic flocculant is more effective in enhancing the slurry settling rate. The small dose of the anionic flocculant is found to be more effective, but the other flocculants are less effective even at higher dosages. The simulation of an industrial thickener was carried out based on the laboratory settling data, and the appropriate design and selection parameters of the industrial thickener were estimated. | Chinthapudi Eswaraiah Surendra Kumar Biswal Barada Kanta Mishra | 2012 | International Journal of Minerals,Metallurgy and Materials2012，19，2： | 28 |
| 2 | Soil-Plant-Microbe Interactions in Stressed Agriculture Management:A Review显示文摘The expected rise in temperature and decreased precipitation owing to climate change and unabated anthropogenic activities add complexity and uncertainty to agro-industry. The impact of soil nutrient imbalance, mismanaged use of chemicals, high temperature,flood or drought, soil salinity, and heavy metal pollutions, with regard to food security, is increasingly being explored worldwide. This review describes the role of soil-plant-microbe interactions along with organic manure in solving stressed agriculture problems. Beneficial microbes associated with plants are known to stimulate plant growth and enhance plant resistance to biotic(diseases) and abiotic(salinity, drought, pollutions, etc.) stresses. The plant growth-promoting rhizobacteria(PGPR) and mycorrhizae, a key component of soil microbiota, could play vital roles in the maintenance of plant fitness and soil health under stressed environments. The application of organic manure as a soil conditioner to stressed soils along with suitable microbial strains could further enhance the plant-microbe associations and increase the crop yield. A combination of plant, stress-tolerant microbe, and organic amendment represents the tripartite association to offer a favourable environment to the proliferation of beneficial rhizosphere microbes that in turn enhance the plant growth performance in disturbed agro-ecosystem. Agriculture land use patterns with the proper exploitation of plant-microbe associations, with compatible beneficial microbial agents, could be one of the most effective strategies in the management of the concerned agriculture lands owing to climate change resilience. However, the association of such microbes with plants for stressed agriculture management still needs to be explored in greater depth. | Shobhit Raj VIMAL Jay Shankar SINGH Naveen Kumar ARORA Surendra SINGH | 2017 | Pedosphere2017，27，2： | 24 |
| 3 | Microbial Degradation of Organophosphate Pesticides: A Review显示文摘Pesticides have become an inevitable part of the modern environment as they are widely used in agriculture,household,and public health sectors and,hence,are extensively distributed throughout most ecosystems.Currently,organophosphate pesticides are the most commercially favored group of pesticides,with large application areas all over the world.Depending on their fate,these organophosphorus compounds may become bioavailable for microbial degradation.Environmental microbes,such as Aspergillus,Pseudomonas,Chlorella,and Arthrobacter,are capable of coupling a variety of physical and biochemical mechanisms for the degradation of organophosphate pesticides,including adsorption,hydrolysis of P–O alkyl and aryl bonds,photodegradation,and enzymatic mineralization.Enzymes,such as esterase,diisopropyl fluorophosphatase,phosphotriesterase,somanase,parathion hydrolase,and paraoxonase,have been isolated from microbes to study and understand the catabolic pathways involved in the biotransformation of these xenobiotic compounds.This review highlights various aspects of biodegradation of organophosphate pesticides along with biological and molecular characterization of some organophosphate pesticide-degrading bacteria. | Shardendu KUMAR Garima KAUSHIK Mohd Ashraf DAR Surendra NIMESH Ulrico Javier LOPEZ-CHUKEN Juan Francisco VILLARREAL-CHIU | 2018 | Pedosphere2018，28，2： | 12 |
| 4 | Pedotransfer Functions for Estimating Soil Hydraulic Properties: A Review显示文摘Characterization of soil hydraulic properties is important to environment management; however, it is well recognized that it is laborious, time-consuming and expensive to directly measure soil hydraulic properties. This paper reviews the development of pedotransfer functions(PTFs) used as an alternative tool to estimate soil hydraulic properties during the last two decades. Modern soil survey techniques like satellite imagery/remote sensing has been used in developing PTFs. Compared to mechanistic approaches,empirical relationships between physical properties and hydraulic properties have received wide preference for predicting soil hydraulic properties. Many PTFs based on different parametric functions can be found in the literature. A number of researchers have pursued a universal function that can describe water retention characteristics of all types of soils, but no single function can be termed generic though van Genuchten(VG) function has been the most widely adopted. Most of the reported parametric PTFs focus on estimation of VG parameters to obtain water retention curve(WRC). A number of physical, morphological and chemical properties have been used as predictor variables in PTFs. Conventionally, regression algorithms/techniques(statistical/neural regression) have been used for calibrating PTFs. However, there are reports of utilizing data mining techniques, e.g., pattern recognition and genetic algorithm.It is inferred that it is critical to refine the data used for calibration to improve the accuracy and reliability of the PTFs. Many statistical indices, including root mean square error(RMSE), index of agreement(d), maximum absolute error(ME), mean absolute error(MAE), coefficient of determination(r^2) and correlation coefficient(r), have been used by different researchers to evaluate and validate PTFs. It is argued that being location specific, research interest in PTFs will continue till generic PTFs are developed and validated. In future studies, improved methods will be required to extract information from the existing database. | Nitin Gorakh PATIL Surendra Kumar SINGH | 2016 | Pedosphere2016，26，4： | 4 |
| 5 | Performance evaluation for selectivity of the flocculant on hematite in selective flocculation显示文摘Increased demand for iron ore necessitates the utilization of low-grade iron ore fines,slimes,and existing tailings.Selective flocculation can be an alternative physico-chemical process for utilizing these low-grade fines,slimes,and tailings.In selective flocculation,the most critical objective is the selection of proper reagents that will make floc of desired minerals.In present study,selective flocculation was applied to ultra-fine synthetic mixtures of hematite and kaolinite,and the Fe value was upgraded up to 65.78% with the reduction of Al2O3 and SiO2 values to 2.65% and 3.66%,respectively.Here,degraded wheat starch was used as a flocculant.In this process,separation occurs on the basis of the selectivity of the flocculant.The selectivity of the flocculant can be quantified in terms of separation effciency.Here,an attempt was also made to develop a correlation between separation effciency and major operating parameters such as flocculent dose,pH value,and solid concentration to predict the separation performance. | Lopamudra Panda Pradip K.Banerjee Surendra Kumar Biswal R.Venugopal N.R.Mandre | 2013 | International Journal of Minerals,Metallurgy and Materials2013，20，12： | 4 |
| 6 | 发展中国家的可再生能源:沼气的机遇和挑战显示文摘能源对于现代社会至关重要,是社会经济发展最重要的指标之一。尽管科技不断发展,但仍然有约30亿人(主要集中在发展中国家的农村地区),继续通过在传统的炉灶中燃烧生物质资源(如柴薪、秸秆、动物粪便)的方式来满足烹饪的能源需求。这种方式对环境、社会、经济、公众健康都带来极大负面影响。这些地区要实现可持续性发展,开发干净清洁、价格低廉的可再生能源就势在必行。把现有的生物质资源(动物粪便、秸秆、餐厨垃圾、绿色废弃物)提炼成更加清洁高效的能源载体(例如厌氧发酵产生的沼气),不仅具有提供清洁、可靠能源的独特潜力,同时又能保护当地和全球的环境。尽管沼气对发展中国家来说意义重大,但其面临着成本高、设备安装和维护专业知识缺乏等问题,因而在地理位置分散的社区难以广泛推广应用。因此,政府和非政府层面的通力协作就显得至关重要,从而促进沼气技术的更新改造和传播,开发尚未被开发的潜力。文章旨在通过分析沼气技术的现状、挑战和潜力,明确它在发展中国家未来的研究方向和发展传播路径。 | K C Surendra Devin Takara rew G Hashimoto Samir Kumar Khanal 李谦 | 2015 | 中国沼气2015，33，1： | 3 |
| 7 | Pathological abnormalities in splenic vasculature in non-cirrhotic portal hypertension:Its relevance in the management of portal hypertension显示文摘BACKGROUND Portal hypertension(PH)is associated with changes in vascular structure and function of the portosplenomesenteric system(PSMS).This is referred to as portal hypertensive vasculopathy.Pathological abnormalities of PSMS has been described in the literature for cirrhotic patients.Raised portal pressure and hyperdynamic circulation are thought to be the underlying cause of this vasculopathy.In view of this,it is expected that pathological changes in splenic and portal vein similar to those reported in cirrhotic patients with PH may also be present in patients with non-cirrhotic PH(NCPH).AIM To investigate pathological abnormalities of splenic vein in patients with NCPH,and suggest its possible implications in the management of PH.METHODS A prospective observational study was performed on 116 patients with NCPH[Extrahepatic portal vein obstruction(EHPVO):53 and non-cirrhotic portal fibrosis(NCPF):63]who underwent proximal splenorenal shunt(PSRS),interposition shunt or splenectomy with devascularization in JIPMER,Pondicherry,India,a tertiary level referral center,between 2011-2016.All patients were evaluated by Doppler study of PSMS,computed tomography portovenogram and upper gastrointestinal endoscopy.An acoustic resonance forced impulse(ARFI)scan and abdomen ultrasound were done for all cases to exclude cirrhosis.Intraoperative and histopathological assessment of the harvested splenic vein was performed in all.The study group was divided into delayed and early presentation based on the median duration of symptoms(i.e.108 mo).RESULTS The study group comprising of 116 patients[77(66%)females and 39(34%)males]with NCPH had a median age of 22 years.Median duration of symptoms was 108 mo.The most common presentation in both EHPVO and NCPF patients was upper gastrointestinal bleeding(hematemesis and melena).The ARFI scan revealed a median score of 1.2(1.0-1.8)m/s for EHPVO and 1.5(0.9-2.8)m/s for NCPF.PSRS was performed in 84 patients(two of whom underwent interposition PSRS using a 10 mm Dacron graft);splenoadrenal shunt in 9;interposition mesocaval shunt in 5;interposition 1st jejunal to caval shunt in 1 patient and devascularization with splenectomy in 17 patients.Median presplenectomy portal pressure was 25(range:15-51)mm Hg.In 77%cases,the splenic vein was abnormal upon intraoperative assessment.Under macroscopic examination,wall thickening was observed in 108(93%),venous thrombosis in 32(28%)and vein wall calcification in 27(23%)cases.Upon examination under a surgical magnification loupe,21(18%)patients had intimal defects in the splenic vein.Histopathological examination of veins was abnormal in all cases.Medial hypertrophy was noted in nearly all patients(107/116),while intimal fibrosis was seen in 30%.Ninety one percent of patients with intimal fibrosis also had venous thrombosis.Vein wall calcification was found in 22%,all of whom had intimal fibrosis and venous thrombosis.The proportion of patients with pathological abnormalities in the splenic vein were significantly greater in the delayed presentation group as compared to the early presentation group.CONCLUSION Pathological changes in the splenic vein similar to those in cirrhotic patients with PH are noted in NCPH.We recommend that PH in NCPH be treated as systemic and pulmonary hypertension equivalent in the gastrointestinal tract,and that early aggressive therapy be initiated to reduce portal pressure and hemodynamic stress to avoid potential lethal effects. | Shahana Gupta Biju Pottakkat Surendra Kumar Verma Raja Kalayarasan Sandip Chandrasekar A Ajith Ananthakrishna Pillai | 2020 | World Journal of Gastrointestinal Surgery2020，12，1： | 3 |

| 12 | Object Matching Across Multiple Non-overlapping Fields of View Using Fuzzy Logic显示文摘An approach based on fuzzy logic for matching both articulated and non-articulated objects across multiple non-overlapping field of views (FoVs) from multiple cameras is proposed. We call it fuzzy logic matching algorithm (FLMA). The approach uses the information of object motion, shape and camera topology for matching objects across camera views. The motion and shape information of targets are obtained by tracking them using a combination of ConDensation and CAMShift tracking algorithms. The information of camera topology is obtained and used by calculating the projective transformation of each view with the common ground plane. The algorithm is suitable for tracking non-rigid objects with both linear and non-linear motion. We show videos of tracking objects across multiple cameras based on FLMA. From our experiments, the system is able to correctly match the targets across views with a high accuracy. | LOKE Yuan Ren KUMAR Pankaj RANGANATH Surendra HUANG Wei-Min | 2006 | 自动化学报2006，32，6： | 1 |
