dependence on chemical fertilizer continually is increasing. continual increasing of using chemicalfertilizer causes nature pollution (e.g. water contamination). this has led researchers to aggressively investigate renewable fertilizer resources, biomass, to produce organic crops and reduced wastage. wormy compost is a bulk solid and biomass feed stocks. wormy compost flow is obstacle as it oft...

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...

drug-in-adhesive transdermal drug delivery systems  )tddss) containing stimulants, termed as energetic substances, such as caffeine and pantothenic acid, were studied. caffeine is a white crystalline substance and a stimulant to central nervous system. in humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. pantothenic acid, al...

Create three-dimensional network of siloxane polymer in the epoxy resin is an appropriate mechanical properties .Dispersion of nanoclay in these coating was prepared by ultrasonication method. Mechanical properties of nanocomposit coatings such as abrasion, hardness and adhesion was increased by addition of nanoclay montmorillonite. Different percentages of nanoclay in coating showed that even ...

While polymers are widely utilized materials in the biomedical industry, they are rarely used in an unmodified state. Some kind of a surface treatment is often necessary to achieve properties suitable for specific applications. There are multiple methods of surface treatment, each with their own pros and cons, such as plasma and laser treatment, UV lamp modification, etching, grafting, metalliz...

objective: in this study we introduced an rgd-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. this peptide was immobilized on a nanofibrous polycaprolactone/gelatin scaffold after which we analyzed human bone marrow-derived mesenchymal stem cells (hbmscs) adhesion and proliferation on this peptide-modified scaffold. methods: nanofibrous...

objective: we introduce an rgd (arg-gly-asp)-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. materials and methods: in this experimental study, the peptide was immobilized on an electrospun nanofibrous polycaprolactone/gelatin (pcl/gel) hybrid scaffold by a chemical bonding approach to improve cell adhesion properties of the scaffold. a...

background and objectives: probiotic bacteria are able to absorb fatty acids present in the culture medium and convert them into intracellular fatty acids, which may affect the physicochemical properties of probiotics. subsequently, changing the composition of cellular fatty acids of probiotics improves the electron acceptance capacity of these microorganisms, and results in an increased adhesi...

the adhesion molecules are involved in adhesion of leukocytes to endothelial cells and other immune cells. not only adhesion molecules have membrane form, but they also have soluble form. in this paper, we attempted to investigate the concen¬tration of soluble adhesion molecules in the type 1 diabetic patients (n = 40) and healthy subjects (n = 10). the results indicated that there was an incre...
