The present study broadly focused on medicinal plant species collected from wild by the villagers for different purposes in the upper catchment of Dhauli Ganga in Nanda Devi Biosphere Reserve(NDBR),in the central Himalaya.A schedule based survey was conducted during the years 2003-2005 in 15 villages of Chamoli district part of the *** was collected from collectors, vaidya(medicine man)and those dealing with domestication and marketing of the medicinal plants. The aim of the study was to understand the prioritiesed medicinal plants,their mode of collection and document their ethnobotanical uses by the Bhotiya tribal communities,in this world heritage site. During the survey,50 medicinal plants belonging to 31 families and 44 genera were *** of these,70% were harvested from the wild,22% were cultivated and 8% were cultivated as well as wild *** the cultivated species,8% were found growing in the kitchen gardens and 14%in the agricultural ***,42%of the plants had their roots and rhizomes used followed by leaves (26%),seeds(10%),seed and leaf(8%),bark and whole plant(6%)and flower(1%).Most plants were reported to be used for rheumatism(16),followed by stomach disorder(14),cold and cough(11),and jaundice(9).Thirty three plants species were reported to have more than one therapeutic uses,while 17 species were reported to be used against single *** distance of villages from road head was one of the factors contributing to the decline in the medicinal plant population in their natural habitats.

Let M be a compact complex manifold of complex dimension two with a smooth K hler metric and D a smooth divisor on . If E is a rank 2 holomorphic vector bundle on M with a stable parabolic structure along D, we prove that there exists a Hermitian-Einstein metric on E’=E|sub> \Dsub> compatible with the parabolic structure, whose curvature is square integrable.

Treatment of severe steroid refractory ulcerative colitis

引用

World Journal of Gastroenterology 2008年第36期14卷 5508-5511页

作者： Gert Van Assche séverine Vermeire Paul Rutgeerts Division of Gastroen-terology University of Leuven Hospitals Herestraat 49 B-3000 Leuven Belgium Division of Gastroenterology University of Leuven Hospitals Herestraat 49 B-3000 Leuven Belgium

Although systemic steroids are highly efficacious in ulcerative colitis (UC), failure to respond to steroids still poses an important challenge to the surgeon and physician alike. Even if the life time risk of a fulminant UC flare is only 20%, this condition is potentially life threatening and should be managed in hospital. If patients fail 3 to 5 d of intravenous corticosteroids and optimal supportive care, they should be considered for any of three options: intravenous cyclosporine (2 mg/kg for 7 d, and serum level controlled), infliximab (5 mg/kg Ⅳ, 0-2-6 wk) or total colectomy. The choice between these three options is a medical- surgical decision based on clinical signs, radiological and endoscopic findings and blood analysis (CRP, serum albumin). Between 65 and 85% of patients will initially respond to cyclosporine and avoid colectomy on the short term. Over 5 years only 50% of initial responders avoid colectomy and outcomes are better in patients naive to azathioprine (bridging strategy). The data on infliximab as a medical rescue in fulminant colitis are more limited although the efficacy of this anti tumor necrosis factor (TNF) monoclonal antibody has been demonstrated in a controlled trial. Controlled data on the comparative efficacy of cyclosporine and infliximab are not available at this moment. Both drugs are immunosuppressants and are used in combination with steroids and azathioprine, which infers a risk of serious, even fatal, opportunistic infections. Therefore, patients not responding to these agents within 5-7 d should be considered for colectomy and responders should be closely monitored for infections.

Effect of welding processes on mechanical and microstructural characteristics of high strength low alloy naval grade steel joints

引用

Defence Technology（防务技术） 2015年第3期11卷 308-317页

作者： s.RAGU NATHAN V.BALAsUBRAMANIAN s.MALARVIZHI A.G.RAO Department of Manufacturing Engineering Annamalai University Centre for Materials Joining & Research (CEMAJOR) Department of Manufacturing EngineeringAnnamalai University Naval Materials Research Laboratory (NMRL)

Naval grade high strength low alloy(HsLA) steels can be easily welded by all types of fusion welding processes. However, fusion welding of these steels leads to the problems such as cold cracking, residual stress, distortion and fatigue damage. These problems can be eliminated by solid state welding process such as friction stir welding(FsW). In this investigation, a comparative evaluation of mechanical(tensile, impact,hardness) properties and microstructural features of shielded metal arc(sMA), gas metal arc(GMA) and friction stir welded(FsW) naval grade HsLA steel joints was carried out. It was found that the use of FsW process eliminated the problems related to fusion welding processes and also resulted in the superior mechanical properties compared to GMA and sMA welded joints.

Transition Metal silicide Nanowires Growth and Electrical Characterization

引用

Chinese Physics Letters 2009年第12期26卷 206-209页

作者：彭祖林 LIANG s. 邓罗根 school of science Beijing Institute of Technology Beijing 100081 science and Engineering of Materials Program Arizona State University Tempe AZ 85287 USA

We report the characterization of self-assembled epitaxially grown transition metal, Fe, Co, Ni, silicide nanowires （TM-NW） growth and electrical transport properties. NWs grown by reactive deposition epitaxy on various silicon surfaces show a dimension of 10nm by 5nm, and several micrometers in length. NW orientations strongly depend on substrate crystal orientation, and follow the substrate symmetry. By using conductive-AFM （c-AFM）, the electron transport properties of one single NW were measured, the resistivity of crystalline nickel silicide NW was estimated to be 2×10-2Ω＆#12539;cm.

In the light of great importance of curves and their frames in many differentbranches of science, especially differential geometry as well as geometric properties andthe uses in various fields, we are interested here to study a special kind of curves calledsmarandache curves in Lorentz 3-space. Then, we present some characterizations for thesecurves and calculate their Darboux invariants. Moreover, we classify TP, TU, PU andTPU-smarandache curves of a spacelike curve according to the causal character of thevector, curve and surface used in the study. Besides, we give some of differential geometricproperties and important relations between that curves. Finally, to demonstrate ourtheoretical results a computational example is given with graph.

THE ADAPTIVE FINITE ELEMENT REMEsHING IN LARGE DEFORMATION OF METAL FORMING

引用

Acta Metallurgica sinica(English Letters) 2004年第3期17卷 323-326页

作者： X.X.Guo J.s.Liu Advanced Manufacturing Technology and Engineering Department Shenzhen Polytechnic Shenzhen 518055ChinaSchool of Material Science and Engineering Taiyuan Heavy Machinery Institute Taiyuan 030024 China

The adaptive remeshing technique for quadrilateral elements consists of modules thetrigger of remeshing, the new mesh generation, adaptive refinement and interpolationof field variables. The new adaptive mesh genemtion is the key problem. First, acoarse mesh is created by using 'loop algorithm'. subsequent local mesh adaptiverefinement is performed based on effective strain. Finally, a typical example of upset-ting is given to test efficient of techniques, from which it is verified that the remeshingalgorithm developed here exhibits good performance and has high accuracy.

Intestinal Kaposi's sarcoma may mimic gastrointestinal stromal tumor in HIV infection

引用

World Journal of Gastroenterology 2007年第33期13卷 4514-4516页

作者： A Zoufaly s schmiedel AW Lohse J van Lunzen Department of Medicine 1 University Medical Center Hamburg-Eppendorf Hamburg Germany Infectious Diseases Unit University Medical Center Hamburg-Eppendorf Hamburg Germany

Diffuse intestinal Kaposi＇s sarcoma shares macroscopic and histopathologic features with gastrointestinal stromal tumors. Correct diagnosis may pose a clinical challenge. We describe the case of a young HIV-1-infected African lady without advanced immunodeficiency, who presented with a diffuse spindle cell tumor of the gut. Initial diagnosis was of a gastrointestinal stromal tumor, based on endoscopy and histopathology. Further evaluation revealed evidence for human herpesvirus 8 （HHV8） and the diagnosis had to be changed to diffuse intestinal Kaposi＇s sarcoma. Antiretroviral triple therapy together with chemotherapy was commenced, and has led to the rapid remission of intestinal lesions. With a background of HIV infection, the presence of HHV8 as the causative agent of Kaposi＇s sarcoma should be determined, as distinct treatment is indicated.
