this study was carried out to evaluate the impacts of organic (sel-plex® selenium yeast) and inorganic (sodium selenite) selenium and vitamin e (d1-α-tocopheryl acetate) on performance and carcass characteristics in broiler chickens. the effect of two types of house temperature and six treatments of feed additives were investigated in a 2×6 factorial experiment at 56 days period with 960 commer...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...

one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
UNLABELLED Hypertension is one of the most important public health problems worldwide. If undiagnosed or untreated, this pathology represents a systemic risk factor and offers unfavorable conditions for dental treatments, especially those requiring bone healing. OBJECTIVES The purpose of this study was to demonstrate, by analysis of bone mineral density (BMD), that the alveolar bone healing p...
This experiment was conducted to study the effect of type of feed processing and type of phytase enzyme on growth performance, calcium, phosphorus tibia and toe ash ,fecal and ileal digestibility of phosphorus in broiler chickens. A total of 420 broiler chicks (Ross 308) were used in a completely random design in the a 2×3 factorial arrangement using two processing methods (pellet and mash) an...
