The viability and differentiation of SaOS-2 preosteoblasts on fiber mats of blends comprising of the biodegradable poly(ester-ether) polydioxanone (PDX) and the sulfate-containing anionic polysaccharides kappa-carrageenan (KCG) and fucoidan (FUC) were investigated for a range of different blend compositions. The detailed analysis of the blend nanofiber properties revealed a different degree of ...

A synthetic blend of chemicals comprising volatiles released by the human body has been shown to be an effective attractant for female Aedes aegypti in olfactometer bioassays with laboratory-reared mosquitoes. We report the laboratory evaluation of Ae. aegypti response to a synthetic blend tested with 4 types of mosquito traps (CDC model 512, CDC model 1012, CFG, and Fay-Prince traps). Aedes ae...

A thermodynamic model of quaternary polymeric solution was developed for membrane formation. It incorporates two mixed solventsN-methyl-2-pyrrolidone (NMP) and tetrahydrofuran (THF), and two high molecular weight polymers cellulose acetate (CA) and polyvinyl chloride (PVC). Also, another polymeric solution was modeled by replacing (CA) with polyvinylpyrrolidone (PVP). The developed model depend...

A new type of cation-exchange nanocomposite membranes was prepared by in-situ formation of ZnO nanoparticles in a blend containing sulfonated poly (2,6-dimethyl-1,4-phenylene oxide) and sulfonated polyvinylchloride via a simple one-step chemical method. As-synthesized nanocomposite membranes were characterized using Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray...

The photodegradation of a 1:1 blend of poly (caprolactone) and poly(vinyl chloride) has been studied by following carbon dioxide emission during UV exposure. Similar measurements were made on poly(caprolactone) and poly(vinyl chloride) homopolymers prepared and irradiated in the same way. It was found that the blend gave lower CO2 emission than either of the two homopolymers, indicating that th...

In this research, we established a modified 45 flammability test for cotton blend material to measure the flammability of nanosilicone softener treated-cotton blend material. The wet pick-up was about 150±10%. b) The specimens were tested in the cross direction and nine specimens were measured. The average percent weight loss of the untreated cotton blend nonwoven is only 0.9%. The percent weig...

OBJECTIVE The present study was carried out to evaluate the toxic effect of blend of some food colors on Swiss albino rats. MATERIALS AND METHODS A blend (1:1:1) of sunset yellow, metanil yellow and tartrazine showed additive effects on serological parameters which indicate that addition of these dye together in food stuff may give rise to more toxic effects than are produced by each dye indi...

this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

Four Holstein steers (466 kg) with cannulas in the rumen and proximal duodenum were used in a 4 X 4 Latin square design experiment to evaluate the ruminal escape protein value and post ruminal digestibility of menhaden fish meal (FM) vs two high-bypass protein blends in an 88% concentrate finishing diet. Blend 1 (B-1) contained 5% fish meal, 25% meat and bone meal, 20% blood meal, and 50% hydro...
