1生物炭和灌水量对土壤保水性及温室番茄生理特性的影响显示文摘为了探究生物炭用量和灌水量对土壤物理性质及作物生长生理特性的影响,采用田间对比试验,以温室番茄为试验对象,设置了3个生物炭施用量处理B0,B1,B2(施用量分别为0,2.5,5.0 kg/m^(2));在每个生物炭处理下设置3个不同灌水量水平T1,T2,T3(分别为1.4Ep,1.2Ep,1.0Ep;Ep为累计水面蒸发量);观测并分析土壤物理性质、番茄生长及光合作用对生物炭施用量和灌水量的响应关系.结果表明,土壤中适当添加生物炭可以有效地增加土壤的保水性,处理B1和B2相对B0增大土壤最大体积含水率为21.9%和32.1%,处理B1有益于土壤的长期持水能力;降低了土壤容重2.5%~16.6%,增加了土壤孔隙度1.9%~10.5%.生物炭施用量在充分灌溉和中度亏缺的处理下均可以有效提高番茄的气孔导度和光合速率,处理B1和B2分别提高番茄叶片的光合速率为11.4%和54.8%;而在重度亏缺的条件下,处理B1和B2抑制了番茄叶片的光合速率16.7%和50.6%.李欣雨 张川 闫浩芳 AKHLAQ Muhammad 李岚兰 张文程 王纪章 2022排灌机械工程学报2022,40,3:8
2Multi-temporal forest cover dynamics in Kashmir Himalayan region for assessing deforestation and forest degradation in the context of REDD+ policy显示文摘The role of forests is being actively considered under the agenda of REDD+(Reducing Emissions from Deforestation and Forest Degradation plus) aimed at reducing emissions related to changes in forest cover and forest quality. Forests in general have undergone negative changes in the past in the form of deforestation and degradation, while in some countries positive changes are reported in the form of conservation, sustainable management of forests and enhancement of carbon stock. The present study in the Kashmir Himalayan forests is an effort to assess historical forest cover changes that took place from 1980 to 2009 and to predict the same for 2030 on the basis of past trend using geospatial modeling approach. Landsat data(Multispectral Scanner(MSS),Thematic Mapper(TM) and Enhanced Thematic Mapper(ETM+)) was used for the years 1980, 1990 and(2001, 2009) respectively and change detection analysis between the dates was performed. The maps generated were validated through ground truthing. The study area(3375.62 km^2) from 1980-2009 has uffered deforestation and forest degradation of about 126 km^2 and 139.02 km^2 respectively which can be claimed under negative options of REDD+, while as the area that experienced no change(1514 km^2) can be claimed under conservation. A small area(23.31 km^2) observed as positive change can be claimed under positive options. The projected estimates of forest cover for 2030 showed increased deforestation and forest degradation on the basis of trend analysis using Cellular Automata(CA) Markov modeling. Despite the fact that country as a whole has registered a net positive change in the past few decades, but there are regions like Kashmir region of western Himalaya which have constantly undergoing deforestation as well as degradation in the past few decades.Akhlaq Amin WANI Pawan Kumar JOSHI Ombir SINGH Sumera SHAFI 2016Journal of Mountain Science2016,13,8:2

10Conserved Quantities in f(R) Gravity via Noether Symmetry显示文摘We investigate f(R)gravity using the Noether symmetry approach.For this purpose,we consider Friedmann Robertson–Walker(FRW)universe and spherically symmetric spacetimes.The Noether symmetry generators are evaluated for some specific choice of f(R)models in the presence of the gauge term.Further,we calculate the corresponding conserved quantities in each case.Moreover,the importance and stability criteria of these models are discussed.M.Farasat Shamir Adil Jhangeer Akhlaq Ahmad Bhatti 2012Chinese Physics Letters2012,29,8:1

20Purification and characterization of CHpro1, a thermotolerant, alkali-stable and oxidation-resisting protease of Chumathang hotspring显示文摘Metagenomic approaches are recently used for searching novel open reading frames(ORFs) coding enzymes employed in pharmaceutical, food industries, etc.In this study, a metagenomic library was constructed from Chumathang hotspring sediment DNA. The library consisted of approximately 9,000 clones and was screened for protease activity. A clone exhibiting protease activity was identified and named CHpro1. Sequencing of CHpro1 revealed that the ORF encoded a functional protein of 363 amino acids belonging to peptidase S8–S53 superfamily.CHpro1 shared 41 % sequence similarity with a reported protease(subtilase family) and 35 % structural similarity with the crystal structure of Pro-Tk sps. of Thermococcus kodarkaenasis. In silico modeling the 3D structure of CHpro1 showed that it has two beta sheets, 10 alpha helices and 11 strands. Catalytic triad prediction implied CHpro1 to be a serine protease. The optimum temperature and p H of the purified protease were found to be 80 °C and 11.0,respectively. The enzyme was active at 5 % concentration of hydrogen peroxide and retained 60 % of activity at 10 %concentration. The thermotolerant, alkalophilic and oxidantstable properties of the protease make it a potential candidate for biotechnological applications.Reena Singh Chirag Chopra Vishnu Kumar Gupta Bashir Akhlaq Vijeshwar Verma Shafaq Rasool 2015Science Bulletin2015,60,14:0
