In order to investigate the effect of seed pretreatment with growth regulators on biochemical characteristics of red bean genotypes, a factorial experiment was carried out in a randomized complete block design with three replications. In this research, seed pretreatment with growth regulators namely salicylic acid (SA) and naphthalene acetic acid (NAA) were applied at four levels including P0: ...
in this research work, the effects of natural fibers such as date palm fiber (df) and jute fiber (jf) on bending properties of polypropylene (pp)/ ethylene–propylene–diene–monomer (epdm) thermoplastic elastomers are investigated. for this purpose, the date palm and jute fibers at five levels of fiber weight fractions (0, 5, 10, 20 and 30 wt. %) are utilized during composite fabrication. maleic ...
An ultrasound-assisted extraction (UAE) method using ethanol was applied for extracting arabinogalactan (AG) and dihydroquercetin (DHQ) simultaneously from larch wood, as a pretreatment for pulping and papermaking. The extraction parameters were optimized by a Box-Behnken experimental design with the yields of AG and DHQ as the response values. Under optimum conditions (three extractions, each ...
The study was carried out to investigate the anticonvulsant effects of different extracts of Bacopa monnieri (BM) against Pentylenetetrazole induced-epilepsy, with special reference to cholinergic metabolism of functionally different skeletal muscles. Rats were divided into eight groups consisted of six rats in each group. (a) control rats treated with saline, (b) PTZinduced epileptic group (60...
The present study was based on the production of bioethanol from alkali-pretreated seed pods Bombax ceiba. Pretreatment is necessary to properly utilize for via fermentation. This process assures accessibility cellulase cellulose found in seedpods by removing lignin. Untreated, KOH-pretreated, and KOH-steam-pretreated substrates were characterized morphological, thermal, chemical changes scanni...
Salt stress significantly limit wheat crop productivity worldwide. Exposure to non-lethal levels of salt stress, referred as "salt-priming", allows plants persist subsequent lethal conditions; the priming effect continues even after an extended stress-free period. This study attempted evaluate effectiveness salt-induced approach cope with toxic effects long-term salinity in wheat. After 22 days...
In this work, Eucalyptus globulus wood was pretreated under non-isothermal autohydrolysis process at 210, 220, and 230 °C, obtaining a pretreated solid with high cellulose content and a hemicellulosic liquid phase (HLP) containing mainly xylose, acetic acid, furfural, xylooligosaccharides, and phenolic compounds. The maximum concentration of xylooligosaccharides (8.97 g/L) and phenolic compound...
In order to investigate changes in substrate chemical and physical features after pretreatment, several characterizations were performed on untreated (UT) corn stover and poplar and their solids resulting pretreatments by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), controlled pH, dilute acid, flowthrough, lime, and SO(2) technologies. In addition to measuring the chemica...
