This study was conducted to assess the effects of feed particle size (FPZ) and crumble size (CZ) of starter diet on growth performance parameters, carcass characteristics, and small intestinal histomorphology in broiler chicks. Three hundred and sixty male Ross 308 chicks were randomly distributed in a completely randomized design with 3 ´ 2 factorial arrangement consist of three screened FPZs ...
There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
ایندومتاسین 1-(p-chlorobanzoyl)-5-methoxy-2-methyl indole-3-acatic acid یک داروی ضد التهاب غیر استروئیدی (nsaid) است . نیمه عمر آن 4ˆ5 ساعت بوده و حداکثر 200 میلی گرم از آن در روز در دوزهای منقسم موارد مصرف متعددی دارد و از جمله در درمان بیماریهایی مانند آرتریت روماتوئید، استئوآرتریت و نقرس بکار میرود. طولانی بودن مدت مصرف دارو و بروز عوارض جانبی گوارشی از مشکلاتی هستند که بیماران مصرف کننده با...
This review basically provided a conceptual framework for sample size calculation in epidemiologic studies with various designs and outcomes. The formula requirement of sample size was drawn based on statistical principles for both descriptive and comparative studies. The required sample size was estimated and presented graphically with different effect sizes and power of statistical test at 95...
The problem of sample size estimation is important in medical applications, especially in cases of expensive measurements of immune biomarkers. This paper describes the problem of logistic regression analysis with the sample size determination algorithms, namely the methods of univariate statistics, logistics regression, cross-validation and Bayesian inference. The authors, treating the regr...
Abstract The effective population size (Ne) of an organism is expected to be generally proportional the total number individuals in a population. In parasites, we might expect host and body size, because both are increase parasite individuals. However, among other factors, populations sometimes so extremely subdivided that high levels inbreeding may distort these predicted relationships. Here, ...
objective(s):iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. super paramagnetic iron oxide (spio) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. in this study, we evaluate the dependency of hydrodynamic si...
myocardial infarction is a common presentation of coronary artery disease and the leading cause of death worldwide. the present study was investigated potential resistance to ischemia-reperfusion (i/r) injuries following administration of methanolic (meoh) extract of scrophularia frigida (s. frigida) in isolated rat heart. male wistar rat hearts (n= 8-10) were isolated and allowed to equilibrat...
abstract government size plays a vital role in the economic development process. therefore, in this study, the existence of a non-linear relationship between government size and economic growth was investigated using the two-sector production function developed by ram (1986). the data, covering 44 years (1961-2005), were collected from the iranian economic information center. two classification...
