a total of 300 one-day old male broilers (cobb 500) were randomly divided into four treatment groups. the groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kgy electron-beam irradiated diets. a total of 5 replicates were performed. the chemical composition of the diet was not affected by irradiation.irradiation doses of 5 an...

Irradiation of polymers is one of the most effective and economical methods for modifying their properties and for changing their applications. In this study, an extrusion grade polypropylene (PP) was treated by electron beam irradiation to produce a PP suitable for injection molding. Irradiation was carried out at different doses (0-80 kGy) under atmosphere air and at ambient temperature. Melt...

background: this cross sectional study was conducted to evaluate the effect of &gamma-rays; and electron-beam irradiation with a commercial toxin binder-milbond-tx on the performance, feed components, and meat quality of japanese quails challenged with aflatoxin b1. methods: overall, 168 one-d-old chicks (japanese quails) were allocated to eight treatments with three replicates based on a compl...

introduction: natural organic matters (noms) existing in water resources led to various problems such as formation of disinfectant by-products (dbps). humic matters like humic acid (ha) are component of noms that should be removed from water. advanced oxidation process (aops) is one of the noms removal methods. the aim of this study was to survey the degradation of humic acid by electron beam i...

Background: The herb feverfew (Tanacetum parthenium L., Asteraceae) has an ancient reputation as an effective anti-inflammatory, analgesic, antipyretic, and anti-asthmatic agent. Parthenolide a gemacranolide-type sesquiterpene lactone is the major constituent of European feverfew. Materials and Methods: The present study was intended to evaluate the in vivo antioxidant potential and radioprotec...

this study was conducted to evaluate the effect of electron beam irradiation at doses of 250 and 500 kgy on the chemical composition and ruminal dry matter (dm) and neutral detergent fiber (ndf) degradability of wheat straw. nylon bags of untreated or irradiated wheat straw were suspended in the rumen of three rams for up to 72 h, and resulting data were fitted to non-linear degradation model t...

OBJECTIVE Since the properties of polymers can be influenced using electron-beam irradiation, the aim of this study was to investigate whether electron-beam post-curing can improve the mechanical properties of experimental denture base polymers. MATERIAL AND METHODS Rectangular specimens of different experimental polymeric blends were electron-beam irradiated (post-cured) with 25 kGy and 200 ...

introduction: humic acids have adverse effects on the water quality, then should be removed from water resources. the aim of this study was to evaluate the effect of nitrate as a radical scavenger for removal of humic acid from aqueous solutions by electron beam irradiation. materials and methods: in this study, after preparation of stock humic acid solution in alkaline condition, different con...

Background: Electron beam irradiation is one of the effective ways to control food-borne pathogens. We evaluated the effect of electron beam irradiation on survival of Escherichia coli O157:H7 and Salmonella enterica serovar Thyphimurium in minced camel meat during refrigerated storage. Methods: The meat samples were inoculated with E. coli O157:H7 and S. enterica serovar Thyphimurium and then...
