Using a longitudinal dataset on ejaculate attributes houbara bustard, we showed that sired by old fathers had different age-dependent trajectories...
Artificial neural networks (ANN) have shown to be a powerful tool for system modeling in a wide range of applications. The focus of this study is on neural network applications to data analysis in egg production. An ANN model with two hidden layers, trained with a back propagation algorithm, successfully learned the relationship between the input (age of hen) and output (egg production) variabl...
objective: aflatoxin b1 (afb1) suppresses the immune system. to decrease such suppressive effects on the immune system, a wide range of herbal medicines like garlic are utilized. biological activities of garlic in vitro and in vivo have also been verified. our previous studies demonstrated that aged garlic (dry garlic bulbs preserved in the freezer for six months at -20˚c) have increased immuno...
Background and purpose:Brucellosis is a disease with zoonotic and transmissible world wide distribution which, often becomes chronic with high rate of recurrence. Since the immune responses during brucellosis have not been studied profoundly, therefore in this study cytokine production in the patients suffering from brucellosis and in healthy individuals has been evaluated. Materials and met...
abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
