Abstract In this part of our tutorial, we attempt to explain and cover several most important non‐imaging parameters that form the complementary base requirements list for an XR system specification. The specification is often treated with less attention, in many cases reason dissatisfactory performances. extensive experience, found critical when designing system, since have very high impact on...

in this study, attempts were made to evaluate the effect of various acrylic acid based carbopols on the release profile of a beta-adrenoreceptor blocking drug, propranolol hcl, from matrix-type tablets invitro. for this purpose, tablets containing 160 mg of propranolol hcl along with various amounts of carbopols 934 (c934), 971 (c971), 974 (c974) and pemulen (pem) were prepared using the wet gr...

Distributed virtual environments (DVEs) have been an active area of research and engineering for more than 20 years. The most widely deployed DVEs are network games such as Quake, Halo, and World of Warcraft (WoW), with millions of users and billions of dollars in annual revenue. Deployed DVEs remain expensive centralized implementations despite significant research outlining ways to distribute...

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...
