The matrix tablets were prepared by using Eudragit L 100, Poly ethylene oxide and Carbopol 971 P. The granules of Zidovudine using above polymers were prepared by direct mixing, wet granulation with water and wet granulation with IPA. The granules were characterized for the morphological study, bulk density, tapped density and particle size distribution. The granules were compressed in to table...

Six upflow anaerobic sludge blanket (UASB) reactors were concurrently operated for 146 d to examine the effects of calcium on the sludge granulation process during start-up. Introduction of Ca at concentrations from 150 to 300mg/l enhanced the biomass accumulation and granulation process. The calcium concentration in the granules was nearly proportional to the calcium concentration in the feed,...

We propose to combine Vehicular Ad Hoc Networks (Vanet) [1][2][3][4][5] and Granular Computing methods collaboratively to investigate the basic principles for knowledge granulation in traffic systems. We present here our achievements in determining fuzzy information granulation as localized distributed information granules within the system and we also present the identified different levels in...

This paper examines granulation structures for stratified rough set approximations. With respect to different level of granulations, various approximations are obtained. Two special types of granulation structures are investigated. A nested sequence of granulations by equivalence relations leads to a nested sequence of rough set approximations. A hierarchical granulation, characterized by a spe...

Medical analysis has been approached by several machine learning methods for many years.Pattern recognition algorithms are capable of improving the quality of prediction, early diagnosis of diseases and disease classification. The classification complications in medical area are solved based on the outcome of medical analysis or report of medical treatment by the medical specialist. This resear...

introduction: otorrhea and granulation tissue in canal wall down mastoidectomy (cwd) is the common problem in cholesteatoma removal and leads to many discomfort for both the patient and the physician. the main objective in cwd is creating the dry cavity, so the topical antibiotic and acetic acid in variable saturations are used for this purpose. in this study we evaluate the effectiveness of to...

Various modeling techniques were used to understand fluidized bed granulation using a two-step approach. First, Plackett-Burman design (PBD) was used to identify the high-risk factors. Then, Box-Behnken design (BBD) was used to analyze and optimize those high-risk factors. The relationship between the high-risk input variables (inlet air temperature X1, binder solution rate X3, and binder-to-po...

The possible participation of cyclooxygenase (COX)-2 in angiogenesis in granulation tissue was analyzed using an air pouch-type carrageenin-induced inflammation model in rats. Injection of carrageenin solution into an air pouch induced gradual increases in the pouch fluid volume and granulation tissue weight as well as angiogenesis in granulation tissue. NS-398 (10-100 microg) inhibited all of ...
