Mechanism of the hypercoagulation effect of hyperoxia

It was shown in man and rabbits that a 30-minute inhalation of a 100% O2 under normal atmospheric pressure was accompanied by an elevation of the blood coagulation capacity and a sharp reduction of the count of platelets with the change of their structure. The trigger mechanism of the described hypercoagulation effect is possibly the viscous metamorphosis of platelets developing under the effect of oxygen activation of Hageman's factor.     

制导仿真数据仓库研究

制导仿真试验和飞行试验都会产生许多数据,数据逐渐累积形成海量数据,针对分析需求对数据进行有效管理,制导仿真数据的管理成为当前国内仿真界面临的难题.鉴于数据仓库管理海量数据、面向分析、支持决策的特性,将数据仓库技术引人到制导仿真数据管理领域,设计出了制导仿真数据仓库的体系架构.针对制导仿真所涉及数据的特点,对制导仿真数据仓库构建过程中先对数据预处理进行研究,提出了制导仿真数据仓库的数据预处理模型,进行仿真证明,模型能有效指导制导仿真数据仓库构的数据预处理工作,可为有关人员快速有效地获取所需数据.     

Response of the glands of internal secretion to chronic administration of strontium-90

A 64-year-old white man with no history of cardiac or bronchopulmonary disease developed acute pulmonary edema shortly after undergoing diagnostic intravenous fluorescein angiography. The patient responded quickly to a course of oxygen, positive pressure breathing, diuretics, and sedation.
