临界水流率是细水雾系统的重要设计参数.为了研究通风条件对细水雾灭火临界水流率的影响,开展了一系列细水雾熄灭木垛火的模拟实验.实验结果表明,对于木垛火,细水雾的临界水流率同时受到热释放速率、有效喷嘴直径、高度、风速和雾化锥角的影响.基于Heskestad的临界水流率预测模型,利用量纲分析得到的指数关系式对实验数据进行拟合,对纳入通风风速后的模型各参数指数进行了修正,从而将其拓展至通风条件下.

高血压患者常规眼底镜检查的价值:系统回顾

世界核心医学期刊文摘（心脏病学分册） 2005年第12期1卷 18-19页

作者： Van Den born b.-J. H. Hulsman C. A. A. Hoekstra J. b. l. 韩瑞娟 Department of Internal Medicine Academic Medical Centre PO 22660 1100 DD Amsterdam Netherlands

Objective: To evaluate the additional value of funduscopy in the routine management of patients with hypertension. Design: Systematic review. Participants: Adults aged 19 or more with hypertensive retinopathy. Data sources: Medline, Embase, and the Cochrane library from 1990. Review methods: Studies were included that assessed hypertensive retinopathy with blinding for blood pressure and cardiovascular risk factors. Studies on observer agreement had to be assessed by two or more observers and expressed as a κstatistic. Studies on the association between hypertensive retinopathy and hypertensive organ damage were carried out in patients with hypertension. The association between hypertensive retinopathy and cardiovascular risk was carried out in unselected normotensive and hypertensive people without diabetes mellitus. Results: The assessment of microvascular changes in the retina is limited by large variation between observers. The positive and negative predictive values for the association between hypertensive retinopathy and blood pressure were low(47%to 72%and 32%to 67%, respectively). Associations between retinal microvascular changes and cardiovascular risk were inconsistent, except for retinopathy and stroke. The increased risk of stroke, however, was also present in normotensive people with retinopathy. These studies did not adjust for other indicators of hypertensive organ damage. Conclusion: Evidence is lacking that routine funduscopy is of additional value in the management of hypertensive patients.

阿瓦斯羊初期用10000条捻转血矛线虫幼虫感染,随后用210000条同样幼虫攻击,并对重复感染的两种反应进行了观察和研究。首先是以虫卵含量明显下降,红细胞压积逐渐升高,以成虫及攻击幼虫死亡为特征,这种现象被认为是自愈和保护。其次是虫卵含量的下降是暂时的,而红细胞压积不是暂时上升,尸体解剖揭示出用幼虫攻击时发生超感染。

稀土元素和记(REY)经常被用作(古)环境条件、元素来源和迁移途径的重建指标。许多地质系统较好地描述了REY行为,但是深海沉积物及其在早期成岩作用中对沉积物产生影响的多种过程,使得关于页岩标准化稀土模式(REYsx)的起源和发展问题没有得到解答。本研究报告了赤道中太平洋克拉里昂-克里帕顿区(CCZ)深海沉积物上部10m沉积物固相和孔隙水的REY数据。固相REY剖面显示5-8 m深度以下的REY浓度最高,REYsv模式显示MREY富集(lasx/Gds在0.35~0.60之间;GdsN/Ybs在1.19~1.47之间)以及无或负CesN和Ysv异常(即显示球粒与亚球粒的YHo比值在24.7~28.7之间)。根据全岩沉积物元素含量和顺序萃取的相关分析,认为磷酸钙相控制了富硅质软泥的粉砂质粘土的稀土分布和模式。MREY在沉积物-水界面开始富集,并随着深度增加而系统性增强。负Cesv异常随着深度而加剧,可能是因为Ce主要与Mn和Fe(羟基)氧化物结合。因此,Ce浓度在整个沉积岩心中保持相对恒定,而其他三价REY元素主要由磷酸钙相控制,磷酸钙相不断地从周围孔隙水中富集REY。对氧化还原不敏感的三价REY浓度随深度增加而增加,通过REY^3+和Na^+对Ca^2+的耦合置换产生或增强负Cess异常。因此,固相REYsv模式由孔隙水REYs模式决定,不适合古海洋学解释。然而,孔隙水和固相REYsv模式的相似性表明,在REY进入磷酸钙晶体结构的过程中,只有轻微的分馏发生。

High-molecular-weight glutenin subunits（HMW-GSs） play a critical role in determining the viscoelastic properties of wheat dough. The HMW-GSs are encoded by Glu-A1, Glu-b1, and Glu-D1 loci on the long arms of chromosomes 1A, 1b, and 1D, respectively. In the present study, four near-isogenic lines with different HMW-GS deletions and compositions at the Glu-A1 and Glu-D1 loci in Yangmai 18 background were used for quality analysis. Deletion in Glu-D1 showed much weaker gluten quality and dough strength than null Glu-A1 genotype and wild genotype（WT）, based on the measurements of sodium dodecyl sulfate（SDS）-sedimentation, lactic acid solvent retention capacity（SRC）, gluten index, development time, stability time, and alveograph P and l values. The deletion of Glu-D1 did not significantly affect grain hardness, grain protein content, water SRC, sodium carbonate SRC, and sucrose SRC. Double null genotype in Glu-A1 and Glu-D1 and single null genotype in Glu-D1 showed significantly higher cookie diameter, crispness, and lower cookie height compared with single null genotype in Glu-A1 and WT. These indicate that the null Glu-D1 genotype is useful for improvement of biscuit quality, and use of this germplasm would be a viable strategy to develop new wheat varieties for biscuit processing.
