la répétition, un mécanisme indispensable pour tout apprentissage dont celui des langues étrangères, paraît, depuis un certain temps, avoir perdu en crédibilité dans les nouveaux ensembles pédagogiques. pourtant nul doute de sa nécessité dans le processus d’enseignement/apprentissage par son effet sur la mémoire. dans cet article, après avoir brièvement rappelé la place de la répétition dans le...

the reproductive range of the iranian population of white tip nematode in rice, aphel-enchoides besseyi, was investigated in vitro to find out a suitable medium as well as a fa-vorable fungal host for monoxenic culturing this nematode. studies were carried out on rice seed associated fungi, pathogenic fungi and one mushroom (agaricus bisporus) grown on three culture media, rpa (rice polish agar...

three groups of 11 new zealand white (nzw) rabbit does, each were reared from 12 weeks of age on iso-energetic diets containing 16, 14 or 12% crude protein (cp) were used to study influences on productive performance, digestibility, some carcass traits, haematological, biochemical and hormonal parameters of rabbit does. the results showed rabbits fed on 16% protein diet had heavier body weights...

cobitis sp. is an endemic spined loach species from the dough river in the southern caspian sea basin, (golestan province, iran). to provide some reproductive features of this fish, sampling was performed at monthly intervals throughout the year and 417 individuals were collected. the specimens ranged in total length from 27.1 to 92.9 mm and total weight from 0.11 to 6.79 g. the spawning of spi...

In this study production, reproduction, population, management and economic parameters resulted from recording of 7 flocks with size 57 to 400 and 721 heads of camels in a cycle of reproduction, during three years from 2011 to 2013 were used to find out of the economic values of important traits in one hump camel in desert areas rearing system. The economic traits that appeared in profit equati...

Objective(s): To benefit from reproduction and deal with challenges in the environmental conditions, animals must adapt internal physiology to maximize the reproduction rate. Maladaptive variations in the neurochemical systems and reproductive system can lead to manifestation of several significant mammalian reprocesses, including mammalian ovarian lifespan. RFamide-related peptide (RFRP, Rfrp)...
