1碾压混凝土坝的温度应力显示文摘对碾压混凝土坝施工期非稳定温度场和应力场进行仿真分析,对空间域用有限单元法离散,在时间域用有限差分法计算。分析与计算中,考虑混凝上徐变时温度应力的影响,一典型工程的计算结果表明:环境温度对碾压混凝土地的最高温升有明显影响,大体积混凝土结构的温度下降到年平均温度需要一个很长的时间过程,混凝土表面的早期裂缝通常在后期闭合,而内部裂缝往往在施工结束几年后发生,因此,混凝土坝后期温度应力是温控设计必须考虑的重要因素之一。张子明 Garga,VK 1995河海大学学报(自然科学版)1995,23,3:13
2寒潮时大体积混凝土的温度应力显示文摘寒潮时大体积混凝土的温度应力张子明,V.K.Garga(河海大学工程力学系)(渥太华大学土木工程系)工程统计资料表明,寒潮袭击是引起大体积混凝土裂缝的重要原因。其中,多数裂缝对结构的危害性不大,但也有一部分由于水泥水化热温度荷载和外荷载的附加影响而发...张子明 Garga,VK 1994河海大学学报(自然科学版)1994,22,6:8
3Surgical strategies for giant medial sphenoid wing meningiomas: a new scoring system for predicting extent of resection显示文摘BACKGROUND: Surgical management of giant medial sphenoid meningiomas (> or =5 cm in maximum dimension) is ex-tremely challenging due to their intimate relationship with vital neural structures like the optic nerve, cranial nerves ofBehari S Giri PJ Shukla D Jain VK Banerji D 2008中国神经肿瘤杂志2008,6,3:7

5Effect of Biophytum sensitivum on streptozotocin and nicotinamideinduced diabetic rats显示文摘Objective:To investigate the effect of aqueous solution of Biophytum sensUiuum leaf extract(BSEt)on normal and strcptozotocin(STZ)-nicotinamide-induced diabetic rats.Methods:Diabetes was induced in adult male Wislar rata by the administration of STZ-nicotinamide(40,110 mg/kg b.w.,respectively)intraperitoneally.BSEt(200 mg/kg)was administered to diabetic rats for 28 days.The effect of extract on blood glucose,plasma insulin,total haemoglobin,glycosylated haemoglobin,liver glycogen and carbohydrate melatxilism regulating enzymes of liver was studied in diabetic rats.Results:BSEt significantly reduced the blood glucose and glycosylated haemoglobin levels and significantly increased the total haemoglobin,plasma insulin and liver glycogen levels in diabetic rats.It also increased the hexokinase activity and decreased glucose-6-phosphatase,fructose-1,6-bisphosphatase activities in diabetic rats.Conclusions:The results of our study suggest that BSEt possesses a promising effecl on STZ-nicotinamide-induced diabetes.Ananda Prabu K Kumarappan CT Sunil Christudas Kalaichelvan VK 2012Asian Pacific Journal of Tropical Biomedicine2012,2,1:5

8电针“足三里”或“阳陵泉”对围产期尼古丁暴露新生鼠肺功能和组织形态的影响显示文摘目的:对比电针母鼠'足三里'与'阳陵泉'穴对围产期尼古丁暴露新生鼠肺功能与组织形态学干预效应的差异,探寻电针防护新生鼠肺发育不良的穴位效应规律。方法:将24只雌性SD大鼠随机分为生理盐水组(S组)、尼古丁组(N组)、尼古丁加足三里组(N+ST 36组)和尼古丁加阳陵泉组(N+GB 34组),每组6只。从受孕第6天开始,S组皮下注射0.9%氯化钠溶液(1 mg/kg);其余3组皮下注射等量尼古丁,至子代大鼠出生后第21天制备围产期尼古丁暴露模型。造模同时N+ST 36组和N+GB 34组分别电针'足三里'和'阳陵泉'穴,每天1次,至子代大鼠出生后第21天。采用小动物肺功能分析系统观察新生鼠吸气峰值流速(PIF)、呼气峰值流速(PEF)、呼气阻力(RE)、吸气阻力(RI)和动态顺应性(Cdyn)等肺功能指标变化;采用HE染色观察肺泡融合、破裂程度等肺组织形态学的变化。结果:与S组比较,N组PEF、Cdyn较低,PIF、RI、RE较高(均P<0.01),肺泡融合、破裂,肺泡壁增厚,肺泡数量减少,肺泡间距变大,肺泡直径较大(P<0.01);与N组比较,N+ST 36组PEF、Cdyn较高,PIF、RI、RE较低(P<0.05,P<0.01),肺泡融合、破裂程度有所改善,肺泡数量增多,肺泡壁变薄,肺泡间距正常,肺泡直径显著减少(P<0.01),而N+GB34组肺功能和肺形态各指标变化不明显(P>0.05)。结论:电针围产期尼古丁暴露孕鼠'足三里'较'阳陵泉'更能明显改善新生大鼠肺功能与肺组织形态。苏杭 嵇波 赵国桢 刘翼天 葛云鹏 戴健 路雅雯 王丹 Reiko Sakurai Rehan VK 严明娜 孙晓敏 白红新 郭孟玮 任晓暄 2019中国针灸2019,39,6:2
