The Efficacy of Suction Drainage in Surgical Operations of Long Bone Fractures in Orthopedics
In this experimental trial , 133 patients with single long bone fracture requiring surgery, admitted in Shahid Mohammadi Hospital (Bandar Abbas/Iran) from June 2002 to April 2003, were randomly devided into two groups. In the first group (72 individuals), after the completion of the operation a single hemovac drain was inserted, while in the second group (61 patients) no drain was used. The two...
متن کاملImpacts of climate change on rainfall extremes and urban drainage systems: a review.
A review is made of current methods for assessing future changes in urban rainfall extremes and their effects on urban drainage systems, due to anthropogenic-induced climate change. The review concludes that in spite of significant advances there are still many limitations in our understanding of how to describe precipitation patterns in a changing climate in order to design and operate urban d...
متن کاملCellular automata algorithms for drainage network extraction and rainfall data assimilation
Since 2002, within the framework of the Cetemps Centre of Excellence at the University of L’Aquila, a distributed grid-based hydrological model (CHYM) has been developed to provide a general purpose model for operational flood warning activity. This paper presents two new cellular automata (CA) algorithms used respectively for drainage network extraction and rainfall data assimilation. The firs...
متن کاملDistribution of a liquid meal within the stomach and gastric emptying after vagotomy and drainage operations.
The intragastric distribution of a radionuclide labelled liquid meal was studied in 62 patients with duodenal ulceration by means of a gamma camera imaging system. A total of 85 gastric emptying studies (23 preoperative and 62 postvagotomy tests) revealed three distinct patterns of distribution. The activity distribution in the stomach after vagotomy showed a slower rate of return and a decreas...
متن کاملA stochastic approach to modeling the role of rainfall variability in drainage basin evolution
We develop a simple stochastic theory for erosion and sediment transport, based on the Poisson pulse rainfall model, in order to analyze how variability in rainfall and runoff influences drainage basin evolution. Two cases are considered: sediment transport by runoff in rills and channels and particle detachment from bedrock or cohesive soils. Analytical and numerical results show that under so...
