3牧草如何生长——植物生长与放牧管理之关联(英文)显示文摘适当管理饲料饲草资源的基本原则是理解多年生牧草如何生长。长期以来 ,对根系生长有了基本的了解 ,对去叶和环境对根系生长的影响也知之甚多。然而 ,对去叶、干旱及其他环境因素对多年生牧草的影响以及这些牧草对去叶的反应缺乏应有的理解。从牧草返青到开花 ,植物处于短枝阶段 ,适度放牧并不对多年生牧草的健康和活力造成危害 ,因为植物会弥补其失去的叶片。然而 ,当牧草从短枝向长枝阶段 (节间伸长和开花期 )转移时 ,碳水化合物主要用于节间伸长和开花过程。在开花后和休眠前期 ,碳水化合物主要向茎基和植物基部转移 ,以供来年新枝条的发育。因此 ,在花后和休眠前期 ,放牧系统必须被调节到“无放牧”状态。“无放牧”状态 ,如休息、轮牧、延迟轮牧和快速轮牧制 ,其价值在于这种定期的禁牧可提高多年生牧草的活力 ,改善草地的健康状况 ,并且在不利的环境条件下 。Ronald E Sosebee David B Wester J Carlos Villalobos Carlton M Britton Changgui Wan Hisham Nofal 2005草业学报2005,14,1:8
4Appropriately adapted properties of hot-extruded Zn-0.5Cu-xFe alloys aimed for biodegradable guided bone regeneration membrane application显示文摘Appropriately adapted comprehensive mechanical properties,degradation behavior and biocompatibility are prerequisites for the application of Zn-based biodegradable implants.In this study,hot-extruded Zn-0.5Cu-xFe(x=0.1,0.2 and 0.4 wt%)alloys were fabricated as candidates for biodegradable materials for guided bone regeneration(GBR)membranes.The hot-extrusion process and Cu alloying were expected mostly to enhance the mechanical properties,and the Fe alloying was added mainly for regulating the degradation.The microstructure,mechanical properties and in vitro degradation behavior were systematically investigated.The ZnCuFe alloys were composed of a Zn matrix and FeZn13 phase.With increasing Fe content,a higher FeZn13 phase precipitation with larger particles was observed.Since elongation declined significantly until fracture with increasing Fe content up to 0.4 wt%,the ZnCuFe(0.2 wt%)alloy achieved a good balance between mechanical strength and ductility,with an ultimate tensile strength of 202.3 MPa and elongation at fracture of 41.2%.Moreover,the addition of Fe successfully accelerated the degradation of ZnCuFe alloys.The ZnCuFe(0.2 wt%)alloy showed relatively uniform corrosion in the long-term degradation test.Furthermore,extracts of the ZnCuFe(0.2 wt%)alloy showed no apparent cytotoxic effects against L929 fibroblasts,Saos-2 osteoblasts or TAg periosteal cells.The ZnCuFe(0.2 wt%)alloy exhibited the potential to inhibit bacterial adhesion of Streptococcus gordonii and mixed oral bacteria.Our study provides evidence that the ZnCuFe(0.2 wt%)alloy can represent a promising material for the application as a suitable GBR membrane.Wentai Zhang Ping Li Gang Shen Xiaoshan Mo Chao Zhou Dorothea Alexander Frank Rupp Jürgen Geis-Gerstorfer Haijun Zhang Guojiang Wan 2021Bioactive Materials2021,6,4:6
5Estimation of methane and nitrous oxide emissions from biomass waste in China:A case study in Hebei Province显示文摘Crop residue,animal manure and MSW are selected as representative biomass waste.Greenhouse gas emissions from treatment and disposal process of biomass waste in Hebei province are estimated for the period from 2002 to 2007,using the methodologies recommended by the Intergovernmental Panel on Climate Change.Greenhouse gas emission was about 10 Mt CO2-equivalent annually.About 6% of greenhouse gas emission came from open burning of crop residue,74% from management system of animal manure,and 20% from MSW disposal.Among all the greenhouse gas sources,landfill is the most concentrated one,and has significant potential of emission reduction.LUO YuXiang1,WANG Wei1,WAN Xiao2,DENG Zhou2 & ZHU CuiPing2 1 Department of Environmental Science and Engineering,Tsinghua University,Beijing 10084,China 2 J&K China Cleaning Energy Technology Company Limited,Beijing 100085,China 2010Science China(Technological Sciences)2010,53,1:6

8新生儿继发于筛窦炎的眼眶脓肿(英文)显示文摘骨膜下脓肿是眼眶蜂窝织炎的一种,以脓和渗出液汇集在眼眶内骨膜下为特点。对于新生儿,眼眶脓肿非常罕见。我们报告1例年龄为26d的右眼患有严重眼眶蜂窝织炎的女患儿。眼眶和副鼻窦CT扫描显示右眼眶蜂窝织炎并内侧骨膜下和眼眶后部脓肿。眼分泌物培养见葡萄球菌生长,经用先锋霉素和甲硝唑静脉注射和经内窥镜鼻窦手术行急诊脓肿引流,恢复良好。通过内窥镜的鼻窦引流手术是预防更严重的并发症的首选治疗。C D Che Mahiran K Wan Mariny J Alagaratnam W H Wan Hazabbah 2008国际眼科杂志2008,8,4:2
