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 ...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
assessing the effects of monensin on economic factors of milk (percents of protein and fat), and quality of milk fat during early lactation. thirteen multiparous holstein cows were blocked into a control and a treatment group from 3 weeks prepartum to 45 days postpartum according the number of their calving. the groups received similar diets. the treatment group received monensin added to grain...
impacts on profitability of dairies, primarily through its impact on average milk/ cow/ day, but also due to its impact on culling and the number of calves born. Despite improved understanding of the financial impacts of poor reproductive management, reproductive efficiency has been on the decline within the dairy industry for the last 50 years. Consequently, producers have expressed renewed in...
background: methionine has been suggested as the firstlimitingamino acid for milk production in ruminants. it is importanthow to increase milk protein yield and milk fat in dairy ruminants.objectives: this study was set to investigate the effect of rumenprotected methionine (rpmet) on milk composition of lactatingcashmere rayeni goats. methods: 40 healthy singletoncashmere rayeni goats about 3 ...
early weanling and rearing of lambs on milk replacer is an important act to increasing flock productivity. two experiments were carried out to compare the voluntary intake and nutrients digestibility ewe milk and commercial milk replacer and their feeding effects on the growth rate, feed intake and feed efficiency of suckling lambs. in experiment 1, eight lambs (two 4-lamb groups) at 31 to 34 d...
