hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...

plants from the genus phyllanthus like phyllanthus muellerianus have long been used in folk medicine for several ailments including fevers, toothache, dysmenorrhea, anemia and paralysis. despite these folkloric uses, there is little scientific data supporting the use of this plant in the management of pain. the purpose of this study is to evaluate the aqueous extract of the aerial parts of phyl...

Blends of chitosan with hydrophilic polymers were investigated for miscibility. Chitosan/poly (vinyl alcohol) (CS/PVA), chitosan/poly vinylpyrollidone (CS/PVP) and chitosan/poly (ethylene oxide) (CS/PEO) blends were prepared in dilute aqueous acetic acid ( = 1 %) and found to be miscible over the entire composition range by dilute solution viscosity and rheological measurements. The miscibility...

spasmolytic, antioxidant, anti-inflammatory and immuno-modulatory properties of ginger (rhizome of zingiber officinale roscoe) suggest that it may has beneficial effects on inflammatory bowel diseases. in the present study, the effect of this herbal extract on a model of acute colitis was evaluated. ginger hydroalcoholic extract with doses of 150, 350, 700 mg/kg, prednisolone (2 mg/kg), or vehi...

conclusions it can be concluded that the rsm is an effective method for the optimization of recombinant protein expression using synthetic genes in e. coli. results the proposed optimum fermentation condition consisted of 7.81 g l-1 glucose, od 600 nm prior induction 1.66 and induction temperature of 30.27°c. the model prediction of 0.267 g l-1 of rhifn-β and 0.961 g l-1 of acetate at the optim...

in this research, the accelerated ripening of the kabkab dates from khalal to tamr using nacl and acetic acid solutions was studied. fruits at khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. nacl solutions, 2. acetic acid solutions and 3. aqueous solution of nacl (1%) and acetic acid. moisture, ph, colour, brix and textural firmness of...

abstract balanced nutrition and soil organic mater are among most important factors affecting yield and quality of grape (vitis vinifera cv.peykani). humic acid as an organic acid derived from humus and other organic sources, in accompany with zinc, and acetic acid can reduce deficiency symptoms in grape. to study the effects of zinc, humic acid and acetic acid on yield and yield components, an...
