Natural dyestuffs, which took the place of synthetic dyestuffs in past, have started to be used consciously again thanks increasing understanding 'environmentally friendly textile'. These natural are mostly obtained from plants or food waste. Coffee is most consumed nutrient world after water. Therefore, there a lot waste coffee nature and it contains pigments that give its color. In this study...

The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). One of the reasons for unique properties of bio-nanocomposites is the difference in physics at nanoscale as compared to that at macroscale. Therefore, the effect of nanoscal...

Introduction: Previous investigations have indicated that the presence of BIO (6-Bromoindirubin-3-Oxime) in medium of some cell culture enhances the cell proliferation and viability. The aim of the present study was to investigate the BIO effects on in vitro expansion of rat marrow-derived mesenchymal stem cells (MSCs) culture. Methods: In the present experimental study, bone marrow cells from ...

background & aim: cassia angustifolia vahl is a valuable medicinal plant that it is important for constipation treatment. according to the importance of organic agriculture in increasing the yield of medicinal plants, the effect of bio-fertilizer on quantities yields of cassia angustifolia vahl or senna in karaj region (iran) was examined. experimental: this research was carried out in rand...

Pyrolysis of Alcea pallida stems was performed in a fixed-bed tubular reactor with and without catalyst at three different temperatures. The effects of pyrolysis parameters including temperature and catalyst on the product yields were investigated. It was found that higher temperature resulted in lower liquid (bio-oil) and solid (bio-char) yields and higher gas yields. Catalysts had different e...

Recently there is a great demand for extending high throughput life science research to biomanufacturing. However, there is a gap from life science research to bio-manufacturing. Most of existing Bio-workflow tools/systems only provide an isolated solution to help bioscientist to orchestrate bio-R&D operations such as bio-database query, bio-computation and analysis etc for specific small bio-p...

this study was conducted to compare the bio-efficacy of herbal methionine (h-met) relative to dl-methionine (dl-met) on 160 “ross 308” broiler chickens. dl-met and h-met were added to the basal diet in eight experimental treatments with three and four concentrations respectively in starter, grower and finisher period. blood parameters which were measured at 24 and 42 days of age consisted of: s...

this experiment was laid out in order to evaluate the effects  of different biofertilizers on yield components of barley. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitroksin, nitrokara and supernitroplass) and three phosphate  biofrtilizers (phosphate barvar2, biozarr and superplass) with control for them and yield components we...
