組織浸出液對於離體蟾蜍心臟搏動的影響
劉次元
科学通报 , 1951,
Abstract: 關於組織療法對於人體血壓的影響,意里潤哥夫的報告指出有73%的病人有减壓現象;27%的病人无变化,其中未發現加壓現象。我們所作关於組織浸出液對於狗血壓影響的初步觀察,也發現略有减壓現象(未發表)。鑑於心臟搏动和血壓的密切關係,为了探求减壓原因是否由於組織液對於心脏搏動的影響,我們作了下面的初步觀察。本試驗用蟾蜍的離體心臟作為觀察的對象,關於離體心臟的裝置方法大致如图一所示,手術操
汉代察举制概论  [PDF]
赖华明?
天府新论 , 2003,
Abstract: 察举制是汉代实行的一种自下而上推选人才为官的制度。通过察举制的实施,汉王朝选拔了一大批德才兼备的人才,不仅充实和加强了中央和地方的封建统治机构,而且对当时社会政治、经济、文化的发展也起了一定的推动作用。弄清楚察举制度产生与演变的规律、特点、内容及其在推行中利弊得失,对于研究汉代的官吏选拔制度和政治管理制度有一定的学术理论意义。

系统工程理论与实践 , 1994,
Abstract: ?本文旨在把模糊数学方法同贝叶斯决策中的预后验决策方法相结合,提供了一个处理这类决策中出现的一些模糊性的方法。这种方法适用范围更广,更接近日常生活中遇到的决策问题。
The Order of Sir Bondi  [PDF]
W. Barreto
Physics , 2009,
Abstract: The direct and indirect relationship between the British physicist originally from Austria, Sir Hermann Bondi, and Venezuelan physics are presented. Special emphasis is made of his more remarkable human qualities, nobility and humbleness, besides his important contribution to General Relativity and to the European science agencies. Self--declared as a staunch disciple of Popperian philosophy, Bondi defended the "hard and dirty" physics against the "inmaculate and beauty" physics. Attention is focused on two cornerstones of Bondi's work, followed thoroughly by Luis Herrera and disciples in Venezuela.
Sir Isaac Newton
E. A. Venter
Koers : Bulletin for Christian Scholarship , 1964, DOI: 10.4102/koers.v32i5&6.1424
Abstract: Die geweldige oplewing van die Christelike wetenskaps- gedagte in ons geeslose tyd, is ongetwyfeld ’n haas onverklaar- bare verskynsel. Dwarsdeur die eeue het Christene ook wetenskap beoefen saam met ongelowiges, maar dit was eers in ons leeftyd dat die principia van die Christelike religie ook vrugbaar gemaak is vir die wetenskapsbeoefening. In hierdie verband sal die name van Dooyeweerd, Vollenhoven, Stoker e.a. steeds met eer vermeld word. Natuurlik het belydende Christene ook voorheen wel deeglik saamgewerk aan die gebou van die wetenskap. Die intieme verband tussen religie, wysbegeerte en wetenskaps- beoefening is toe egter nog nie suiwer ingesien nie. Uit hier- die tydperk dateer die arbeid van sir Isaac Newton.
前北京研究院动物学研究所派员赴察北参加察蒙鼠疫防治工作

科学通报 , 1950,
Abstract: 前北京研究院动物学研究所助理研究员夏武平及其助手胡振淅已定於四月一日赴察北协助中央卫生部之「察蒙鼠疫防治所」工作。去年察北及内蒙鼠疫流行,因发觉较迟,处理仓促,不仅这次鼠疫发生的情况未能确实了解,而且估计上今年这—区域鼠疫发生的可能性很大,所以卫生部才设立这个防治所。这个防治所的任务:一方面在预防鼠疫的发生,并在一旦发生时可以及时阻止其蔓延,不
An Interview with Sir Michael Marmot  [cached]
Editors
Social Medicine , 2009,
Abstract: In August of 2008 the WHO Commission on the Social Determinants of Health concluded its work with the publication of a report entitled: “Closing the gap in a generation: Health equity through action on the social determinants of health.” The Commission’s chair, Sir Michael Marmot, was kind enough to answer our questions about the Commission’s recommendations. This interview was conducted by email in May of this year. Social Medicine: We congratulate the Com-mission on its excellent work in bringing attention to the social determinants of health and the Commission’s call for health equity. We appreciated the Commission’s recognition that: “Social Justice is a matter of life and death.” We were also happy that the Commission included representatives of civil society in their work. This was an important affirmation of democratic values. When thinking about health inequalities people often use the analogue of the ladder to show how the gradient of worsening health outcomes affects all people in society except (presumably) those at the very top. Thinking about the ladder leads us to pose the following question: Is making the ladder shorter (i.e. reducing inequalities) the only approach to inequalities or is it possible to imagine making the ladder disappear entirely? Sir Michael Marmot: All societies have hier-archies. It is not conceivable, therefore, to have a society with no ladder. The conceptual framework of the Commission on Social Determinants of Health leads us to think of at least two (linked) ways to address the relation between position on the ladder and health: act at the societal level to reduce social inequalities, and break the link between position in the social hierarchy and health. The first argues for reducing the slope of the social gradient. To see this, suppose, just for a moment, that the ladder were defined on the basis of years of education. People who had three years or fewer had life expectancy of 50 years, those who had 13 years or more had life expectancy of 80 and the rest were ranged in between in a graded way: the social gradient in health. Now if we had a societal change so that everyone had at least 10 years of education, and better health followed as a result, the magnitude of health inequity would be reduced. We have reduced inequities by making the ladder shorter. [...]

Abstract: 为满足我国卫星导航系统状态切换中地影时间确定以及卫星轨道确定中太阳辐射压建模等需求,本文针对GEO、IGSO、MEO三类导航卫星,采用柱形与锥形地影模型进行了地影因子及本影区持续时间差异分析。在此基础上以地影期持续天数,本影区持续时间为分析对象,对卫星轨道根数与地影状态之间的关系进行了深入研究。
