Different molecular species of interleukin 1 (IL 1) were examined for the spectrum of responses elicited in human endothelial cells (HEC), including synthesis of prostacyclin (PGI2), tissue-type procoagulant activity (PCA), platelet activating factor (PAF), and plasminogen activator inhibitor (PA-I). The IL 1 preparations utilized for the present study included a natural, partially purified IL ...

The performance of two popular hydraulic models (HEC-RAS and WSPG) for modeling hydraulic jump in an open channel is investigated. The numerical solutions are compared with a new experimental data set obtained for varying channel bottom slopes and flow rates. Both the models satisfactorily predict the flow depths and location of the jump. The end results indicate that the numerical models outpu...

with the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. many site-specific methods have been proposed for modeling indoor radio channels. among these methods, the ray tracing algorithm and the finite-difference time domain (fdtd) method are the most popular ones. the ray tracing approach ...

This research was conducted in the Lower Ping River Basin downstream of the Bhumibol Dam and the Lower Wang River Basin in Tak Province, Thailand. Most of the tributary streams of the Ping can be considered as ungauged catchments. There are 10pumping station installation at both river banks of the Ping in Tak Province. Recently, most of them could not fully operate due to the water amount in th...

The complexity of modern scientific software is an important issue that needs to be addressed as part of an effort to revitalize high end computing (HEC). The complexity arises from both the scientific demands and the increasingly complex computers on which the software is run. We believe that HEC software developers need to be able to use a higher level of abstraction to express their computat...
