| 1 | Catalytic performances of kaoline and silica alumina in the thermal degradation of polypropylene显示文摘Polypropylene was cracked thermally and catalytically in the presence of kaoline and silica alumina in a semi batch reactor in the temperature range 400℃~550℃ in order to obtain suitable liquid fuels.The dependencies between process temperatures,types of catalyst,feed compositions and product yields of the obtained fuel fractions were found.It was observed that up to 450℃ thermal cracking temperature,the major product of pyrolysis was liquid oil and the major product at other higher temperatures(475℃~550℃) are viscous liquid or wax and the highest yield of pyrolysis product is 82.85% by weight at 500℃.Use of kaoline and silica alumina decreased the reaction time and increased the yield of liquid fraction.Again the major pyrolysis product in catalytic pyrolysis at all temperatures was low viscous liquid oil.Silica alumina was found better as compared to kaoline in liquid yield and in reducing the reaction temperature.The maximum oil yield using silica alumina and kaoline catalyst are 91% and 89.5% respectively.On the basis of the obtained results hypothetical continuous process of waste polypropylene plastics processing for engine fuel production can be presented. | Achyut K Panda R K Singh | 2011 | 燃料化学学报2011，39，3： | 15 |
| 2 | Plant endemism in the Nepal Himalayas and phytogeographical implications显示文摘Nepal is located in the central part of the greater Himalayan range with a unique series of mountain chains formed by recent mountain building geological events. As one of the youngest mountains in the world it contributes to diversity of plants and also provided barriers to and corridors through which plants migrated during the ice ages. The higher altitudinal variation with the high mountains, deep river valleys and lowland plains combine with the effects of the summer monsoon and dry winter result with an extraordinary diversity of ecosystems including flora and fauna in a relatively small land area. The existing checklists for Nepal record some 6000 species of flowering plants and about 530 ferns. However, the botanical experts estimate that numbers may go up to 7000 when the poorly known remote regions are fully explored. The information on plant endemism in Nepal Himalaya is not adequately known as Nepal is still struggling to complete long awaited Flora of Nepal project. Endemic species are confined to specific areas and are the first to be affected by land use and other global changes. We sought to explore the spatial distribution of endemic plant species in Nepal in relation to the consequences associated with climatic and geologic changes over time in the region with the help of published literature. It was found that the endemism showed marked spatial variation between open moist habitat and dry inner valleys, the former with higher endemism. The updated records showed 312 flowering plant species to be endemic to Nepal with higher endemism around the elevation of 3800e4200 m at sea level. The recent human population explosion, intensified deforestation, habitat fragmentation and modern day environmental changes are posing greater threats to endemic plant in Nepal. The conservation status and threats to these peculiar species are unknown. Nevertheless, environmental degradation and high poverty rates create a potent mix of threats to biodiversity in this landscape. | Achyut Tiwari Yadav Uprety Santosh Kumar Rana | 2019 | Plant Diversity2019，41，3： | 5 |
| 3 | Residual stress measurement for injection molded components显示文摘Residual stress induced during manufacturing of injection molded components such as polymethyl methacrylate(PMMA) affects the mechanical and optical properties of these components. These residual stresses can be visualized and quantified by measuring their birefringence. In this paper, a low birefringence polariscope(LBP) is used to measure the whole-field residual stress distribution of these injection molded specimens. Detailed analytical and experimental study is conducted to quantify the residual stress measurement in these materials. A commercial birefringence measurement system was used to validate the results obtained to our measurement system. This study can help in material diagnosis for quality and manufacturing purpose and be useful for understanding of residual stress in imaging or other applications. | Achyut Adhikari Thomas Bourgade Anand Asundi | 2016 | Theoretical & Applied Mechanics Letters2016，6，4： | 3 |

| 6 | Blue sheep in the Annapurna Conservation Area,Nepal:habitat use,population biomass and their contribution to the carrying capacity of snow leopards显示文摘The Himalaya region of Nepal provides a habitat for the endangered snow leopard(Panthera uncia)and its principal prey species,the blue sheep(Pseudois nayaur).The aim of this study was to describe the habitat,the distribution and the population structure of blue sheep,and to estimate their contribution to the carrying capac-ity of snow leopard in the upper Mustang region of Nepal.Blue sheep were recorded at altitudes from 3209-5498 m on slopes with gradients of 16-60°and aspects of 40°NE to 140°SE.A total of 939 blue sheep were counted in the upper Mustang region,and 98 were counted in the Yak Kharka region of Manang district;how-ever,upper Mustang had the lowest population density of blue sheep recorded within their distribution range in Nepal(0.86 blue sheep/km^(2)).The results of the study show that a higher density of blue sheep is associated with greater plant species diversity.The most important species present in the blue sheep habitat were Kobresia pyg-maea,Artemesia spp.,Lonicera spp.,Lancea tibetica,Poa spp.,Astragalus spp.and Ephedra gerardiana.It is estimated that the existing blue sheep population biomass of approximately 38925 kg in the upper Mustang re-gion could support approximately 19 snow leopards(1.6 snow leopards/100 km^(2)). | Achyut ARYAL Dianne BRUNTON Weihong JI David RAUBENHEIMER | 2014 | Integrative Zoology2014，9，1： | 2 |
