in the present study, floating drug delivery beads (fdds) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. in order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the consti...

conclusions conservative management is successful in the vast majority of patients with spinal headache. interventional procedures are required in a small fraction of patients for symptomatic relief. case presentation intrathecal drug delivery system (idds) was initially used for the management of chronic malignant pain; it has since been used to manage pain from other nonmalignant conditions a...

Performance and resource optimization is an important research problem in data intensive distributed computing. We present a new batched stream processing model that captures query correlations to expose I/O and computation redundancies for optimizations. The model is inspired by our empirical study on a trace from a production large-scale data processing cluster, which reveals significant redu...

Gas hydrate growth kinetics was studied at a pressure of 90 bars to investigate the effect of temperature, initial water content, stirring rate, and reactor size in stirred semi-batch autoclave reactors. The mixing energy during hydrate growth was estimated by logging the power consumed. The theoretical model by Garcia-Ochoa and Gomez for estimation of the mass transfer parameters in stirred ta...

Abstract The k -means algorithm is widely used for clustering, compressing, and summarizing vector data. We present a fast memory-efficient GPU-based exact -means, Asynchronous Selective Batched K (ASB -means). Unlike most algorithms that require loading the whole dataset onto GPU amount of memory required to run our can be chosen much smaller than size dataset. Thus, cluster datasets whose exc...
