1Species diversity, regeneration and dominance as influenced by canopy gaps and their characteristics in tropical evergreen forests of Western Ghats, India显示文摘Canopy gaps play a significant role in maintaining structure and composition of tropical forests. This study was carried out in tropical evergreen forests of central Western Ghats in India to understand the influence of canopy gap size and the relationship of gap regime attributes to diversity measures and regeneration. The average gap size in the study area was found to be 396 m2 and around half of gaps were 4–8 years old. Gaps created by natural single tree fall were smaller in size but significantly higher in number. Diversity and regeneration of woody species were compared with canopy gaps and intact vegetation. Species richness and diversity was higher in gaps than in intact vegetation. Macaranga peltata, a shade intolerant species dominated gaps while intact vegetation was dominated by shade tolerant Kingiodendron pinnatum.Gap size significantly influenced species diversity and regeneration. Gap area and age were significantly and negatively correlated with diversity measures but positively correlated with regeneration. Among all the attributes of gaps, regeneration was significantly positively correlated with light intensity. Gaps maintained species diversity and favored regeneration of woody species. In addition to gap size and age, other gap ecological attributes also affected species diversity and regeneration.Guddappa Mahalingappa Devagiri Anil Kumar Khaple Siddagangaiah Mohan Puttanaik Venkateshamurthy Sanjay Tomar Arkalgud Nagaraja Arunkumar Geeta Joshi 2016Journal of Forestry Research2016,27,4:9
2Per oral cholangiopancreatoscopy in pancreatico biliary diseases- Expert consensus statements显示文摘AIM: To provide consensus statements on the use of per-oral cholangiopancreatoscopy(POCPS).METHODS: A workgroup of experts in endoscopic retrograde cholangiopancreatography(ERCP), endosonography, and POCPS generated consensus statements summarizing the utility of POCPS in pancreaticobiliary disease. Recommendation grades used validated evidence ratings of publications from an extensive literature review.RESULTS: Six consensus statements were generated:(1) POCPS is now an important additional tool during ERCP;(2) in patients with indeterminate biliary strictures, POCS and POCS-guided targeted biopsy are useful for establishing a definitive diagnosis;(3) POCS and POCS-guided lithotripsy are recommended for treatment of difficult common bile duct stones when standard techniques fail;(4) in patients with main duct intraductal papillary mucinous neoplasms(IPMN) POPS may be used to assess extent of tumor to assist surgicalresection;(5) in difficult pancreatic ductal stones,POPS-guided lithotripsy may be useful in fragmentation and extraction of stones; and(6) additional indications for POCPS include selective guidewire placement,unexplained hemobilia, assessing intraductal biliary ablation therapy, and extracting migrated stents. CONCLUSION: POCPS is important in association with ERCP, particularly for diagnosis of indeterminate biliary strictures and for intra-ductal lithotripsy when other techniques failed, and may be useful for preoperative assessment of extent of main duct IPMN, for extraction of difficult pancreatic stones, and for unusua indications involving selective guidewire placement,assessing unexplained hemobilia or intraductal biliary ablation therapy, and extracting migrated stents.Mohan Ramchandani Duvvur Nageshwar Reddy Sundeep Lakhtakia Manu Tandan Amit Maydeo Thoguluva Seshadri Chandrashekhar Ajay Kumar Randhir Sud Rungsun Rerknimitr Dadang Makmun Christopher Khor 2015World Journal of Gastroenterology2015,21,15:8
3Recent advances in catalytic combustion of AP-based composite solid propellants显示文摘Composite solid propellants(CSPs) have widely been used as main energy source for propelling the rockets in both space and military applications. Internal ballistic parameters of rockets like characteristic exhaust velocity, specific impulse, thrust, burning rate etc., are measured to assess and control the performance of rocket motors. The burn rate of solid propellants has been considered as most vital parameter for design of solid rocket motors to meet specific mission requirements. The burning rate of solid propellants can be tailored by using different constituents, extent of oxidizer loading and its particle size and more commonly by incorporating suitable combustion catalysts. Various metal oxides(MOs),complexes, metal powders and metal alloys have shown positive catalytic behaviour during the combustion of CSPs. These are usually solid-state catalysts that play multiple roles in combustion of CSPs such as reduction in activation energy, enhancement of rate of reaction, modification of sequences in reaction-phase, influence on condensed-phase combustion and participation in combustion process in gas-phase reactions. The application of nanoscale catalysts in CSPs has increased considerably in recent past due to their superior catalytic properties as compared to their bulk-sized counterparts. A large surface-to-volume ratio and quantum size effect of nanocatalysts are considered to be plausible reasons for improving the combustion characteristics of propellants. Several efforts have been made to produce nanoscale combustion catalysts for advanced propellant formulations to improve their energetics. The work done so far is largely scattered. In this review, an effort has been made to introduce various combustion catalysts having at least a metallic entity. Recent developments of nanoscale combustion catalysts with their specific merits are discussed. The combustion chemistry of a typical CSP is briefly discussed for providing a better understanding on role of combustion catalysts in burning rate enhancement. Available information on different types of combustion nanocatalysts is also presented with critical comments.Narendra Yadav Prem Kumar Srivastava Mohan Varma 2021Defence Technology(防务技术)2021,17,3:8
4Expression profile of cholecystokinin type-A receptor in gallbladder cancer and gallstone disease显示文摘BACKGROUND:Regulatory peptide receptors have attracted the interest of oncologists as a new promising approach for cancer pathology,imaging and therapy.Although cholecystokinin (CCK) is a potent modulator of gallbladder contractility and plays a potential role in pancreatic carcinogenesis through CCK type-A receptor (CCKAR),its role in gallbladder cancer (GBC) is still unknown and immunohistochemical detection of CCKAR in the gallbladder has not yet been reported.This novel case-control study aimed to investigate the expression profile of CCKAR in GBC and gallstone disease (GSD).METHODS:This study included 162 samples of gallbladder:94 from GBC and 68 from GSD.Expression of CCKAR was analyzed by immunohistochemistry and immunoblotting.The results were statistically correlated with disease history including age,sex,presence of gallstone,stage and differentiation.RESULTS:CCKAR was positive in 30/68 (44.1%) of GSD and 72/94 (76.6%) of GBC samples.Fifty-one of the 72 (70.8%) CCKAR-positive GBC samples showed over-expression.Interestingly,consistent results also appeared in the immunoblotting study.CONCLUSIONS:CCKAR expression was significantly increased in GBC compared to GSD.Moreover,CCKAR expression was associated with the degree of tumor differentiation,i.e.,less expression in poorly-differentiated tumors.Thus,it has future prognostic and therapeutic implications in the management of GBC.Rajani Rai Mallika Tewari Mohan Kumar Tej Bali Singh Hari S Shukla 2011Hepatobiliary & Pancreatic Diseases International2011,10,4:7
5Retinal structural-vascular-functional relationship using optical coherence tomography and optical coherence tomography -angiography in myopia显示文摘Background:To examine the retinal structure–vascular-function relationship using optical coherence tomography(OCT)and optical coherence tomography angiography(OCTA)in myopia.Methods:This was a prospective cross-sectional study comprising 86 eyes of 45 individuals with varying axial lengths and spherical equivalents and no posterior segment abnormalities.All eyes underwent optical coherence tomography with the Spectralis SD-OCT and OCTA with RTVue-XR Avanti;Optovue.Individual macular retinal layer thicknesses and flow areas and vessel densities were measured on OCT and OCTA,respectively.Linear correlations were made between the macular layer thicknesses,flow areas and vessel densities with axial length,spherical equivalent and visual acuity.Results:The participants’mean ages were 33.34±14.45 years,mean spherical equivalent refractions were−7.17±5.71 D and axial lengths were 25.95±2.41 mm.There were significant positive correlations of foveal angle(r=0.757,p=0.001),inner retinal(r=0.764,p=0.001)and outer plexiform layer(r=0.771,p=0.001)thickness on OCT and vessel densities in deep capillary plexus(r=0.313,p=0.003)on OCTA with axial length and negative correlations with spherical equivalents and visual acuity.Significant negative correlations of outer nuclear layer(r=−0.560,p=0.03)and photoreceptor outer segment layer thickness(r=−0.856,p<0.001)were noted on OCT with axial length and positive correlations with spherical equivalents and visual acuity.Conclusion:The lateral retinal stretching in myopia could possibly explain the correlation between retinal layer thickness,vascular density and visual acuity in these eyes.Further research is required to investigate this.Ramesh Venkatesh Shivani Sinha Deepika Gangadharaiah Santosh G.K.Gadde Ashwin Mohan Rohit Shetty Naresh Kumar Yadav 2019Eye and Vision2019,6,1:7

7在稍尖的巨大的肺的栓塞的机械故障和 thrombolysis : 未来的试用显示文摘 AIM: To assess role of combined modality of mechanical fragmentation and intralesional thrombolysis in patients with massive pulmonary embolism presenting subacutely. METHODS: Eight of 70 patients presenting in tertiary care centre of North India with massive pulmonary embolism within 4 years had subacute presentation (symptom onset more than 2 wk). These patients were subjected to pulmonary angiography with intention to treat basis via mechanical breakdown and intra lesional thrombolysis. Mechanical breakdown of embolus was accomplished with 5-F multipurpose catheter to reestablish flow, followed by intralesional infusion of urokinase (4400 IU/kg over 10 min followed by 4400 IU/kg per hour over 24 h). RESULTS: Eight patients, mean age 47.77±12.20 years presented with subacute pulmonary embolism (mean duration of symptoms 2.4 wk). At presentation, mean heart rate, shock index, miller score and mean pulmonary pressures were 101.5±15.2/min, 0.995±0.156, 23.87±3.76 and 37.62±6.67 mmHg which reduced to 91.5±12.2/min (P=0.0325), 0.789±0.139 (P=0.0019), 5.87±1.73 (P=0.0000004) and 27.75±8.66 mmHg (P=0.0003) post procedurally. Mean BP improved from 80.00±3.09 mmHg to 90.58±9.13 mmHg (P=0.0100) post procedurally. Minor complications in the form of local hematoma-minor hematoma in 1 (12.5%), and pseudoaneurysm (due to femoral artery puncture) in 1 (12.5 %) patient were seen. At 30 d and 6 mo follow up survival rate was 100% and all the patients were asymptomatic and in New York Heart Association class 1. CONCLUSION: Combined modality of mechanical fragmentation and intralesional thrombolysis appears to be a promising alternative to high risk surgical procedures in patients with subacute massive pulmonary embolism.Bishav Mohan Shibba Takkar Chhabra Naved Aslam Gurpreet Singh Wander Naresh Kumar Sood Sumati Verma Anil Kumar Mehra Sarit Sharma 2013World Journal of Cardiology2013,5,5:5
8All ileo-cecal ulcers are not Crohn's:Changing perspectives of symptomatic ileocecal ulcers显示文摘AIM To investigated clinical,endoscopic and histopathological parameters of the patients presenting with ileocecal ulcers on colonoscopy.METHODS Consecutive symptomatic patients undergoing colonoscopy,and diagnosed to have ulcerations in the ileocecal(I/C) region,were enrolled.Biopsy was obtained and theirclinical presentation and outcome were recorded.RESULTS Out of 1632 colonoscopies,104 patients had ulcerations in the I/C region and were included in the study.Their median age was 44.5 years and 59% were males.The predominant presentation was lower GI bleed(55,53%),pain abdomen ± diarrhea(36,35%),fever(32,31%),and diarrhea alone(9,9%).On colonoscopy,terminal ileum was entered in 96(92%) cases.The distribution of ulcers was as follows:Ileum alone 40%(38/96),cecum alone 33%(32/96),and both ileum plus cecum 27%(26/96).The ulcers were multiple in 98% and in 34% there were additional ulcers elsewhere in colon.Based on clinical presentation and investigations,the etiology of ulcers was classified into infective causes(43%) and noninfective causes(57%).Fourteen patients(13%) were diagnosed to have Crohn's disease(CD).CONCLUSION Non-specific ileocecal ulcers are most common ulcers seen in ileo-cecal region.And if all infections are clubbed together then infection is the most common(> 40%) cause of ulcerations of the I/C region.Cecal involvement and fever are important clues to infective cause.On the contrary CD account for only 13% cases as a cause of ileo-cecalulcers.So all symptomatic patients with I/C ulcers on colonoscopy are not Crohn's.Jay Toshniwal Romesh Chawlani Amit Thawrani Rajesh Sharma Anil Arora Hardik L Kotecha Mohan Goyal Vijendra Kirnake Pankaj Jain Pankaj Tyagi Naresh Bansal Munish Sachdeva Piyush Ranjan Mandhir Kumar Praveen Sharma Vikas Singla Rinkesh Bansal Vineet Shah Sunita Bhalla Ashish Kumar 2017World Journal of Gastrointestinal Endoscopy2017,9,7:5
9Impact of Land-Use Change on Soil Microbial Community Composition and Organic Carbon Content in the Dry Tropics显示文摘Restoration of forests poses a major challenge globally, particularly in the tropics, as the forests in these regions are more vulnerable to land-use change. We studied land-use change from natural forest(NF) to degraded forest(DF), and subsequently to either Jatropha curcas plantation(JP) or agroecosystem(AG), in the dry tropics of Uttar Pradesh, India, with respect to its impacts on soil microbial community composition as indicated by phospholipid fatty acid(PLFA) biomarkers and soil organic carbon(SOC) content. The trend of bacterial PLFAs across all land-use types was in the order: NF > JP > DF> AG. In NF, there was dominance of gram-negative bacterial(G^-) PLFAs over the corresponding gram-positive bacterial(G^+) PLFAs. The levels of G^- PLFAs in AG and JP differed significantly from those in DF, whereas those of G^+ PLFAs were relatively similar in these three land-use types. Fungal PLFAs,however, followed a different trend: NF > JP > DF = AG. Total PLFAs, fungal/bacterial(F/B) PLFA ratio, and SOC content followed trends similar to that of bacterial PLFAs. Across all land-use types, there were strong positive relationships between SOC content and G-, bacterial, fungal, and total microbial PLFAs and F/B PLFA ratio. Compared with bacterial PLFAs, fungal PLFAs appeared to be more responsive to land-use change. The F/B PLFA ratio, fungal PLFAs, and bacterial PLFAs explained 91%, 94%,and 73% of the variability in SOC content, respectively. The higher F/B PLFA ratio in JP favored more soil C storage, leading to faster ecosystem recovery compared to either AG or DF. The F/B PLFA ratio could be used as an early indicator of ecosystem recovery in response to disturbance, particularly in relation to land-use change.Chandra Mohan KUMAR Nandita GHOSHAL 2017Pedosphere2017,27,5:5

11Determination of flavonoids,polyphenols and antioxidant activity of Tephrosia purpurea:a seasonal study显示文摘OBJECTIVE:Tephrosia purpurea(Linn.) Pers.is widely used in traditional medicine to treat liver disorders,febrile attacks,enlargement and obstruction of liver,spleen,and kidney.In the present study,investigations were carried out to determine the seasonal impact on the content of flavonoid glycosides and on antioxidant activities so as to identify the optimal time of harvesting.METHODS:The plant materials were collected in different seasons during 2013-2014.Air-dried,powdered plant materials were extracted with 95%ethanol and ethanokwater(1:1) by ultrasound-assisted extraction process.Their chemical composition in terms of total polyphenol and flavonoid contents(TPCs and TFCs) was determined using modified colorimetric Folin-Ciocalteu method and aluminum chloride colorimetric assay respectively.To determine the in vitro antioxidant activity,diphenyl-picryl hydrazyl(DPPH) radical-scavenging assay and total antioxidant capacity by phosphomolybdate antioxidant assay were carried out.High-performance liquid chromatography(HPLC)/photo-diode array(PDA) analysis was used to quantify the flavonoid glycosides in the samples collected in different seasons.Correlation studies were also carried out between antioxidant activities and TPCs.RESULTS:The highest TPC and TFC were found to be in the 95%ethanolic extract of the August sample and the lowest in the 50%hydro-alcoholic extract of the plant sample collected in winter season.It was observed that in both the assays used to determine the antioxidant activity,the 95%ethanolic extracts in all the seasons showed a higher activity than their respective 50%hydroalcoholic extracts with an increase in activity as we go from cold to hot to rainy seasons.Based on correlation analysis,DPPH radical-scavenging activities as well as the spectrophotometrically measured phosphomolybdenum complex were also strongly correlated with TPC of the extracts.The most abundant flavonoid glycoside was quercetin-3-O-rhamnoglucoside in all the seasons.The content of all flavonoids was observed highest in the 95%ethanolic extract of the plant collected in August(TP-3).The 50%hydro-alcoholic extract of the plant collected in December(TP-6) showed the lowest amount of flavonoids and antioxidant activity.CONCLUSION:The findings of this study confirmed that the metabolism and production of flavonoids in T.purpurea are vigorously affected by seasonal factors.Significant differences were observed in the TPC,TFC and flavonoid glycoside composition in the 95%ethanolic as well as 50%hydro-alcoholic extracts of T.purpurea collected in different seasons.Since the 95%ethanolic extract of the August sample(TP-3),which also happens to be its flowering season,exhibited the highest TPC.TFC and antioxidant activities in both DPPH and phosphomolybdate assays as well as contained the highest content of all flavonoids,it could be recommended as the optimal season of harvesting T.purpurea with respect to its pharmaceutically important constituents,i.e.,flavonoids.Madan Mohan Pandey Sayyada Khatoon Subha Rastogi Ajay Kumar Singh Rawat 2016Journal of Integrative Medicine2016,14,6:3
12Numerical Visualization of Air Intake Induced by Free Surface Vortex显示文摘Free surface vortex control is vital in a pump sump system because the air absorbed by free surface vortex induces noise, vibration, and cavitation corrosion on the pumping system. In this study, the change of free surface vortex and air absorption in a pump intake has been investigated by the Volume of Fraction(VOF) method with steady multiphase flow model in order to represent the behavior of the free surface vortex exactly. The homogeneous free surface model is used to apply interactions of air and water. The results show that air intake by the free surface vortex motion can be visualized using the iso-surface of air volume fraction. The vortices make an air column from the free surface to the pump intake. Also, it was found that the free surface vortex can be controlled by installing curtain walls.Young Kyu Park Mohan Kumar Dey Yoon Hwan Choi Yeon Won Lee 2017Journal of Thermal Science2017,26,6:3
13柚皮苷改善束缚性应激引起的小鼠生化指标及行为变化的一氧化氮调节机制(英文)显示文摘目的:研究柚皮苷对束缚性应激引起的小鼠生化指标改变、行为变化及线粒体功能紊乱的影响。方法:将小鼠按照体质量随机分组,分别给予不同药物治疗14 d。在第15天让所有小鼠接受束缚性应激刺激6 h,然后在接受各种不同的行为测试后处死。取小鼠的大脑匀浆进行各种生化指标测量和线粒体功能分析。结果:6 h的急性束缚性应激刺激能显著改变小鼠的行为(焦虑和记忆),引起生化指标变化和线粒体功能紊乱。用柚皮苷预处理(50或100 mg/kg口服)14 d则能显著减轻急性束缚性应激刺激引起的小鼠行为和生化指标变化以及线粒体功能紊乱(P<0.05);而使用一氧化氮的前体左旋精氨酸预处理(50 mg/kg腹腔注射)可以拮抗柚皮苷的保护效应(P<0.05)。此外,采用左旋精氨酸甲酯预处理(5 mg/kg腹腔注射)则导致柚皮苷的保护效应增强。结论:柚皮苷对束缚性应激刺激引起的小鼠行为和生化指标变化以及线粒体功能紊乱的保护作用与氮能神经通路有关。Gollapalle L.Viswanatha Hanumanthappa Shylaja K.Sadashiva Sandeep Rao Yathiraj Ashwini V.Ramaiah Santhosh Kumar C.Gangadharaiah Mohan Venkate Gowda Sunil M.Venkateshappa Sarvesh Kumar Subbanna Rajesh 2011中西医结合学报2011,9,11:3
14浸泡和冷预处理对喜马拉雅长叶松不同种源种子萌发的作用(英文)显示文摘对喜马拉雅长叶松种子进行24小时GA3和H2O2浸泡预处理和15d的2-3℃低温预处理后,研究了在20℃,25℃和30℃萌发条件下,21个不同种源的喜马拉雅长叶松种子的萌发情况。结果表明,H2O2(1%v/v)和GA3(10mg/L)浸泡预处理,种子萌发率分别是82.39%和78.19%,而未经预处理的种子平均萌发率为70.79%。GA3和H2O2浸泡预处理分别使种子萌发时间缩短了8d和10d。在超过21天的20℃萌发条件下,湿冷处理提高了种子萌发率和缩短了萌发时间;而在25℃和30℃萌发条件下,总的萌发率未受到影响。喜马拉雅长叶松种子因缺少休眠而表现出很好的萌发,但是因为越来越多的造林项目需要大量的种子,播种预处理有利于提高种子萌发率和萌发速率,有助于满足种子需求。Sunil Kumar Ghildiyal Chandra Mohan Sharma Vinod Prasad Khanduri 2009Journal of Forestry Research2009,20,4:3
15Effect of replenishment of vitamin D on survival in patients with decompensated liver cirrhosis:A prospective study显示文摘AIM To assess the vitamin D(VD) deficiency as a prognostic factor and effect of replenishment of VD on mortality in decompensated cirrhosis. METHODS Patients with decompensated liver cirrhosis were screened for serum VD levels. A total of 101 VD deficient patients(< 20 ng/mL) were randomly enrolled in two groups: Treatment group(n = 51) and control group(n = 50). Treatment group received VD treatment in the form of intramuscular cholecalciferol 300000 IU as loading dose and 800 IU/d oral as maintenance dose along with 1000 mg oral calcium supplementation. The VD level, clinical parameters and survival of both the groups were compared for 6-mo.RESULTS Prevalence of vitamin D deficiency(VDD) in decompensated CLD was 84.31%. The mean(SD) age of the patients in the treatment group(M:F: 40:11) and control group(M:F: 37:13) were 46.2(± 14.93) years and 43.28(± 12.53) years, respectively. Baseline mean(CI) VD(ng/mL) in control group and treatment group were 9.15(8.35-9.94) and 9.65(8.63-10.7), respectively. Mean(CI) serum VD level(ng/mL) at 6-mo in control group and treatment group were 9.02(6.88-11.17) and 29(23-35), respectively. Over the period of time the VD, calcium and phosphorus level was improved in treatment group compared to control group. There was nonsignificant trend seen in greater survival(69% vs 64%; P > 0.05) and longer survival(155 d vs 141 d; P > 0.05) in treatment group compared to control group. VD level had no significant association with mortality(P > 0.05). In multivariate analysis, treatment with VD supplement was found significantly(P < 0.05; adjusted hazard ratio: 0.48) associated with survival of the patients over 6-mo. CONCLUSION VD deficiency is very common in patients of decompensated CLD. Replenishment of VD may improve survival in patients with decompensated liver cirrhosis.Ashish Kumar Jha Sharad Kumar Jha Amarendra Kumar Vishwa Mohan Dayal Sanjeev Kumar Jha 2017World Journal of Gastrointestinal Pathophysiology2017,8,3:2

17Climate change and finger millet: Perception, trend and impact on yield in different ecological regions in Central Nepal显示文摘The views of local people on climate change along different ecological regions are relatively unexplored in Nepal. This study was conducted in 13 villages in central Nepal at different altitudes to document the views of small holder farmers and compare their perception with trends of climatic variables, finger millet yield, natural disasters, plant phenology(flowering and fruiting), status of forest and wild life, as well as the spread of diseases and pests. Analysis on the climatic data of stations for 36-41 years between 1975 and 2016 showed significant increases in the minimum temperature in lower tropical climatic region(<500 m), upper tropical to subtropical climatic region(500-2000 m) and temperate climatic region(2000-3000 m) by 0.01, 0.026 and 0.054℃/year, respectively, and an increase of maximum temperature by 0.008, 0.018, and 0.019℃/year, respectively. Rainfall showed a strongly significant decreasing trend in all elevation regions. This result matches with the views of respondents except 38% respondent from temperate climatic region. People from the temperate climatic region also mentioned that current onset of snowfall is delayed but amount of snowfall remained the same. From the documented records, except events of wild fire, frequency of natural disasters events have increased in the recent years, which was in harmony with the views of local people. Multi-linear regression analysis showed that contribution of climatic variables on finger millet yield in lower tropical climatic region and upper tropical to subtropical regions was 23% and 57.3%, respectively, which was supported by increasing trend on average growing degree day(GDD) temperature at the rate of 0.01℃ in upper tropical to subtropical region and 0.007℃ in lower tropical climatic region yearly. Finger millet yield has been increasing at the rate of 7.39 and 36.9 kg/ha yearly in lower tropical climatic region and upper tropical to subtropical climatic region, respectively. This result provides deeper understanding of people's perception of causes and effects of climate change on diverse variables along different elevation and related magnitude which can contribute to policy making in Nepal.Dol Raj LUITEL Mohan SIWAKOTI Pramod Kumar JHA 2019Journal of Mountain Science2019,16,4:2
