The most desirable approach to improve characteristics such as yield with polygenic inheritance and genotype × environment interaction, is simultaneous selection using selection index based on related traits. This study was conducted Research Farm of Isfahan University of Technology, to compare selection indices for barley yield improvement under nitrogen stress and non stress conditions, usi...
Descriptive theories of economic growth involve the analysis of the time path of a model economy for various initial conditions and growth parameters. Normative theories study the existence and properties of intertemporally optimal growth trajectories using some kind of social objective function. Few examples of either class allow for the adjustment of preference, knowledge, technology and beha...
This paper investigates the existence and asymptotic behavior of solutions for weighted p t Laplacian integro-differential system with multipoint and integral boundary value condition in half line. When the nonlinearity term f satisfies subp− − 1 growth condition or general growth condition, we give the existence of solutions via Leray-Schauder degree. Moreover, the existence of nonnegative sol...
The aim of this study was to record the length-weight relationship and condition factor of A. maculatus from Persian Gulf coastal waters. The specimens were collected on a monthly basis from April to March 2013. Overal 766 specimens were caught. Size and weight of collected fish ranged between 13/2-48 cm and 31.2-1820 gr. The Condition of the growth fish was allometrically negative with b val...
With regard to the importance of polychaete Perinereis nuntia in diet of shrimp broodstock, achieving its breeding and culture bio technique is an important goal in shrimp industry. For this purpose, usage of diets inducing the highest growth and the lowest mortality is of importance. The effect of four different dietary treatments including commercial shrimp diet- Biomar, Lansy shrimp diet con...
several strains of saccharomyces cerevisiae were isolated from different sources. these strains were under taken for ethanol tolerance analysis and growth under stress condition. exponential phase to various concentrations of ethanol (2–26% v/v) for 1 h was used for isolation of resistant strains. viable cells were isolated and purified by inoculation of diluted samples on yeast extract peptone...
This study developed probabilistic models to describe Listeria monocytogenes growth responses in meat products with low concentrations of NaNO2 and NaCl. A five-strain mixture of L. monocytogenes was inoculated in NBYE (nutrient broth plus 0.6% yeast extract) supplemented with NaNO2 (0-141 ppm) and NaCl (0-1.75%). The inoculated samples were then stored under aerobic and anaerobic conditions at...
this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...
