The effects of stocking density of eggs and larvae were studied related to the morphological deformities appearance, percentage of survival, and growth rate, in order to achieve the most suitable stocking density for eggs and larvae in incubators and rearing tanks. The egg stocking densities were 500, 700 and 900 g per incubator for great sturgeon, 500 and 1000g per incubator for Persian sturge...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
Two experiments were conducted to study the effects of stocking density on growth performance, carcass yield, and foot pad lesions of White Pekin ducks from hatch to 14 d of age (experiment 1) and from 14 to 42 d of age (experiment 2), respectively. All ducks were reared in raised plastic wire-floor pens with a pen size of 30 m(2), and males and females were mixed at a ratio of 1:1 in each pen ...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
in order to estimate responses of growth rate and growth hormone of clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-l tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. on day 30 and 60, the fish growth rates were measured, pituitary growth hormone (gh) mrna levels and serum gh concentrations were examined by real-time qpcr and elisa te...
OBJECTIVES The aim of the present study was to assess the outcome in anti-PL12 patients with antisynthetase syndrome (ASS). METHODS The medical records of anti-PL12 (n=5) patients with ASS were retrospectively analyzed without prior selection. To exclude false-positive patients, we included patients who were successively tested positive for anti-PL12 antibody at least twice by immunodot and/o...
The aim of this study was to determine the optimal stocking density in koi carp (Cyprinus carpio var. Koi). For this reason, 2400 juvenile koi (1.28 ± 0.11 g) were stocked at five levels of density (50, 100, 150, 200 and 300 fish per m3) and reared for 11 weeks and growth performance, survival rate, and hematological parameters were evaluated. There was no significant difference between first t...
A study was conducted to evaluate the effects of varying dietary vitamin D3 and stocking density on growing performance, carcass characteristics, bone biomechanical properties, and welfare responses in Ross (308) broilers. Experimental diets, containing 1, 10, or 20 times the NRC recommended level of vitamin D3 (200 IU/kg), were formulated with low, medium, or high vitamin D3 levels for 3 growi...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
effect of globacid® acidifier in different stocking densities on performance and blood metabolites was examined using 576 one-day broiler chickens ross 308 in a completely randomized design with 6 treatments and four replications for each treatment through a (3 × 2) factorial arrangement with three levels of stocking densities (14, 16 and 18 chicks per square meter) and two levels of globacid® ...
