3高动态动脉僵硬度指数是普通中年人群年龄相关的肾小球滤过率快速下降的一个独立危险因素显示文摘Eriksen BO, Stefansson VT, Jenssen TG, Mathisen UD, Schei J, Solbu MD, Wilsgaard T, Melsom T. High ambulatory arte- rial stiffness index is an independent risk factor for rapid age-related glomerular filtration rate decline in the general middle- aged population. Hypertension, 2017,69 (4) : 651-659.动脉僵硬度是心血管病及慢性肾脏病的危险因素。流行病学研究难以足够精确测定肾小球滤过率(glomerular filtration rate, GFR),普通人群中,动脉僵硬度做为年龄相关GFR下降的预测因素,作用仍不明确。动态动脉僵硬度指数( ambulatory arterialstiffness index, AASI) 是一个易于从动态血压中计算得到的动脉僵硬度推荐指标。该研究在普通人群中评估AASI是否可预测碘海醇清除率评估的GFR下降。Eriksen BO Stefansson VT Jenssen TG Mathisen UD Schei J Solbu MD Wilsgaard T Melsom T 赵狄 练桂丽 2017中华高血压杂志2017,25,3:8
4Response of Wheat to Tillage Plus Rice Residue and Nitrogen Management in Rice-Wheat System显示文摘Zero tillage with residues retention and optimizing nitrogen fertilization are important strategies to improve soil quality and wheat(Triticum aestivum L.) yield in rice(Oryza sativa L.)-wheat system. Field experiments were conducted on silty clay soil(Hyperthermic, and Typic Torrifluvents) in D. I. Khan, Pakistan, to explore the impact of six tillage methods(zero tillage straw retained(ZTsr), ZT straw burnt(ZTsb), reduced tillage straw incorporated(RTsi, including tiller and rotavator), RT straw burnt(RTsb), conventional tillage straw incorporated(CTsi, including disc plow, tiller, rotavator, and leveling operations), CT straw burnt(CTsb)) and five nitrogen rates, i.e., 0, 100, 150, 200, and 250 kg ha-1 on wheat yield. Mean values for N revealed that spikes m-2, grains/spike, 1 000-grain weight(g), and grain yield(kg ha-1) were significantly higher at 200 kg N ha-1 in both the years as well as mean over years than all other treatments. Mean values for tillage revealed that ZTsr produced highest number of spikes m-2 among tillage methods. However, grains/spike, 1 000-grain weight, and grain yield were higher in tillage methods with either straw retained/incorporated than tillage methods with straw burnt. Interaction effects were significant in year 1 and in mean over years regarding spikes m-2, 1 000-grain weight, total soil organic matter(SOM), and total soil N(TSN). ZTsr produced the most spikes m-2 and 1 000-grain weight at 200 kg N ha-1. ZTsr also produced higher SOM and TSN at 200-250 kg N ha-1 at the end of 2 yr cropping. Thus ZTsr with 200 kg N ha-1 may be an optimum and sustainable approach to enhance wheat yield and soil quality in rice-wheat system.Khalid Usman Ejaz Ahmad Khan Niamatullah Khan Abdur Rashid Fazal Yazdan Saleem Ud Din 2014Journal of Integrative Agriculture2014,13,11:6

6Revalorization of CO2 for methanol production via ZnO promoted carbon nanofibers based Cu-ZrO2 catalytic hydrogenation显示文摘A series of novel carbon nanofibers(CNFs)based Cu-ZrO2 catalysts were synthesized by deposition precipitation method.To investigate the influence of promoter,catalysts were loaded with 1,2,3 and 4 wt%ZnO and characterized by ICP-OES,HRTEM,BET,N2O chemisorption,TPR,XPS and CO2-TPD techniques.The results revealed that physicochemical properties of the catalysts were strongly influenced by incorporation of ZnO to the parent catalyst.Copper surface area(SCu)and dispersion(DCu)were slightly decreased by incorporation of ZnO promoter.Nevertheless,SCuand DCuwere remarkably decreased when ZnO content was exceeded beyond 3 wt%.The catalytic performance was evaluated by using autoclave slurry reactor at a pressure and temperature of 30 bar and 180℃,respectively.The promotion of CuZrO2/CNFs catalyst with 3 wt%of ZnO enhanced methanol synthesis rate from 32 to 45 g kg^-1 h^-1.Notably,with the ZnO promotion the selectivity to methanol was enhanced to 92%compared to 78%of the un-promoted Cu-ZrO2/CNFs catalyst at the expense of a lowered CO2 conversion.In addition,the catalytic activity of this novel catalyst system for CO2 hydrogenation to methanol was compared with the recent literature data.Israf Ud Din Maizatul S.Shaharun A.Naeem S Tasleem Pervaiz Ahmad 2019Journal of Energy Chemistry2019,28,12:6

8Developing Wheat for Improved Yield and Adaptation Under a Changing Climate: Optimization of a Few Key Genes显示文摘世界上雨养无灌溉条件下种植的小麦常常受到干旱的影响。针对未来气候的模拟预测显示,除非采用适当的品种,否则温度上升和降雨模式的联合作用将加剧这种干旱情况,并可能造成小麦大幅度减产。由于物候基因的多样性,小麦具有广泛的适应性。小麦物候学提供了一个根据目标环境中可用水改变作物的发育阶段从而提高抗旱性。本文综述了春化(Vrn)、光周期(Ppd)和矮秆(Rht)基因等小麦物候学研究的最新进展。在不同气候条件下Vrn和Ppd基因的等位基因、单倍型和拷贝数有不同的反应,因而不仅可以改变发育阶段,而且可以改良产量。与模式植物拟南芥(Arabidopsis thaliana)相比,还有更多尚未发现的小麦物候基因,在目标环境中量化其效应将有助于通过育种提高小麦的耐旱性。因此,通过配置适当的物候基因、Rht基因和其他耐旱性相关的重要生理性状的组合,可以在水资源有限的环境中使产量最大化。M.A.N.

9Analysis of the effect of passive measures on the energy consumption and zero-energy prospects of residential buildings in Pakistan显示文摘Climate change can adversely impact the thermal comfort and energy efficiency of the buildings stock. The South Asian countries are particularly vulnerable to the adverse impacts of climate change specially in the form of rising temperatures and increasing frequency of heat waves. The passive building design measures can be useful in mitigating and adapting to the climate change by increasing energy efficiency and reducing greenhouse gas (GHG) emissions. In this study various passive climate change adaptation measures (PCAMs) have been used individually and in form of combinations in order to analyze their impact on the energy efficacy of residential buildings in Pakistan. It has been found that the natural ventilation and front green wall are the most efficient options for reducing the overall energy consumption. By implementation of these PCAMs, cooling demand can be decreased by 27.75% while heating demand can be reduced by 35%. Secondly, the prospect of net zero-energy building and reduced CO2 emissions are also studied. It has been shown that building can achieve net-zero energy on an annual basis at every orientation and it can attain the status of nearly zero-energy building on a monthly basis. Moreover, emitted CO2 can be reduced by 31% by using the renewable energy.Muhammad Wasim Anwar Zaib Ali Abdullah Javed Emad Ud Din Muhammad Sajid 2021Building Simulation2021,14,4:3
