Sintered Ti6Al4V powder compacts potentially to be used in implant applications were prepared using commercially available spherical and angular powders (100-200 mum) within the porosity range of 34-54%. Cylindrical green powder compacts were cold compacted at various pressures and then sintered at 1200 degrees C for 2 h. The final percent porosity and mean pore sizes were determined as functio...

in order to formulate an efficient and durable mucoadhesive drug delivery system, careful consideration of formulation-related parameters is critical. this study was conducted to investigate the effect of the presence of various types and concentrations of surfactants within or outside carbopol 934 (c934) as well as hydroxypropylmethyl cellulose (hpmc) solid compacts, on their duration of mucoa...

Porosities of set and burnout compacts of phosphate-bonded investments were determined. A gas pycnometer was used to measure the volumes, and hence the densities, of fine powders and porous compacts. Porosities of set and burnout compacts were then obtained from these data for as-received powders and dry set compacts by a numerical simulation method, subsequently leading on to the estimated com...

The National Council of State Boards of Nursing (NCSBN) became the first organization to develop and implement two interstate compacts to reduce regulatory barriers to cross-border nursing practice for licensed practical/vocational nurses, registered nurses, and advanced practice registered nurses. The compacts were intended to move from the traditional single-state license to a state-of-reside...

Abstract: Dissolution and recovery of Mn-Al compacts with and without a chloride flux was studied by taking samples from the melt after addition of the compact. Events occurring after the addition of the compacts into the melt were studied using water quenched specimens after holding them for a specified time in molten state. The cross sections of these specimens were characterized by SEM a...

Purpose: The aim of this study was to enhance the dissolution rate of Cyclosporine A, a poorly water-soluble drug by developing a self micro-emulsifying (SME) tablet formulation by using the liquisolid compact technique. A liquisolid system is formed by converting a liquid formulation into a dry, free-flowing and compressible powder mixture with selected carrier material and coating material. T...

A chemically bonded phosphate ceramic material has been prepared for the sake of encapsulating lead battery waste. In this paper the optimum conditions for the preparation of magnesium potassium phosphate compacts are determined and the formation of the final product assessed using XRD. The effect of applied pressure and pressing duration as well as the Mg:K molar ratio on the porosity and perm...
