OBJECTIVES To determine the efficacy of 400 mcg sublingual misoprost as an adjunct to suction evacuation in first trimester pregnancy termination. METHOD(S) During the study period of January2006-June 2007, two hundred twenty-one pregnant women wanting first trimester pregnancy termination were randomised into two groups. In the study group of one hundred twenty-one women, sublingual misopros...

Inferior vena cava (IVC) filters have become essential components in deep vein thrombosis treatment, and are particularly critical for preventing pulmonary embolisms in anticoagulation-resistant patients. Filter efficacy relies on maintaining IVC patency, or openness, by preventing filter-induced thrombosis following clot capture. A computational fluid dynamics (CFD) model has been developed to...

Grouping behaviour occurs often in crowd evacuation. On the one hand, groups are needed for efficient evacuation. On the other hand, large uncontrolled groups (herds) may cause clogging and increase panic. The mechanisms of emergence of leaders and groups in complex socio-technical systems with intelligent technical components are not well understood. This paper presents the first attempt to un...

This paper presents a stochastic model for emergency evacuation simulation such as for a subway station. The model, MCEVAC was developed using Monte Carlo and a macro-simulation technique; the model includes a number of random variables, such as occupant load, initial occupant load, and pre-evacuation time. A random event of a train fire including fire location, fire growth rate, and the effect...

In this paper, the use of Fire Dynamics Simulator (FDS) and its evacuation module, Evac for modelling fire and people evacuation in a road tunnel is illustrated. For given fire scenario and traffic situation in the tunnel, behaviour of individual evacuees as well as groups of evacuees is analyzed in order to demonstrate the impact of fire on people evacuation. Some specific features of the use ...

We introduce an open-source software Aamks for fire risk assessment. This article focuses on a component of Aamks – an evacuation simulator named a-evac. A-evac models evacuation of humans in the fire environment produced by CFAST fire simulator. In the article we discuss the probabilistic evacuation approach, automatic planning of exit routes, the interactions amongst the moving evacuees and t...

Objective—The relative balance between clot formation and fibrinolysis is considered to reflect thrombotic potential following vascular injury. The aims of the present study were to (1) to determine the contribution of genetic and environmental factors to variance in measures of clot structure/function in the Leeds Family Study, and (2) to determine the relationship between measures of clot str...

BACKGROUND AND PURPOSE We studied in monkeys why vasospasm resolves after subarachnoid hemorrhage (SAH). METHODS Monkeys underwent angiography and right (n=17) or bilateral (n=8) SAH. Animals with bilateral SAH underwent angiography 1, 3, 5, and 7 days later. Animals with right SAH underwent angiography 7 days later. The clot was then not removed (n=5), removed and replaced with fresh clot (n...
