The aim of the present study was to develop and characterise polymeric composite pellets by means of continuous melt extrusion techniques. Powder blends of a steroid hormone (SH) as a model drug and either ethyl cellulose (EC N10 and EC P7 grades) or hydroxypropyl methylcellulose (HPMC AS grade) as polymeric carrier were extruded using a Pharma 11mm twin screw extruder in a continuous mode of o...

Nanotubes have been shown to possess intriguing mass transport properties, and are being incorporated into polymeric membranes for molecular separations. Although models have been developed to predict the effective permeability and selectivity of composite membranes with non-spherical fillers, they only apply to fillers with isotropic transport properties. However, molecular transport in tubula...

Non-destructive testing (NDT) is a quality control measure designed to ensure the safety of products according established variability thresholds. With development advanced technologies and lack formalised knowledge state-of-the-art, National Composites Centre, Bristol, has identified that increasing complexity composite will lead some severe inspection challenges. To address apparent gap under...

Reverse osmosis (RO) concentrate from wastewater reuse facilities contains concentrated emerging pollutants, such as pharmaceuticals. In this research, a paper-like composite sheet consisting of titanium dioxide (TiO2) and zeolite was synthesized, and removal of the antipruritic agent crotamiton from RO concentrate was studied using the TiO2/zeolite composite sheet. The RO concentrate was obtai...

When combining item types within assessments, it is important to consider the reliability of scores for each item type and the reliability of composite scores. This study investigated the effect of scoring procedures, section weights, and numbers of items per section on reliability, error variance, and conditional standard errors of measurement, using multivariate generalizability theory techni...

Composite nanoarchitectures represent a class of nanostructured entities that integrates various dissimilar nanoscale building blocks including nanoparticles, nanowires, and nanofilms toward realizing multifunctional characteristics. A broad array of composite nanoarchitectures can be designed and fabricated, involving generic materials such as metal, ceramics, and polymers in nanoscale form. I...

over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (tfc) membranes. in advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (tfn) membranes. however, in the last generation of tfns, an ultrathin selective film of nanoparticles is coated...

background: combination chemotherapy is accepted as a high efficacy treatment for gastric cancer, whereas choice of standard treatment is unclear. multiple chemotherapeutic regimens have been used to achieve higher efficacy and lower toxicity. this study was designed to evaluate the treatment results of advanced gastric cancer with capecitabine and oxaliplatin regimen. subjects and methods : al...
