animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. nitrogen has been identified as the foremost source of nonpoint water pollution  and the potential negative impacts of n have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing aa supply to the duodenum. ruminal proteolysis...

moving in line with the postulation that metadiscourse (md) markers help transform a dry and tortuous piece of text into a coherent and reader-friendly one, the researchers in the current study attempted to investigate the effect different metadiscourse markers might have on iranian efl learners’ perception of written texts. to this end, 120 undergraduate english students were given three diffe...

Background & Aims: In recent years, molecular methods for characterizing genetic heterogeneity have found a major place in modern approaches. In this study, two different molecular techniques including Restriction Fragment Length Polymorphism (RFLP) and Multi Locus microsatellite typing (MLMT) were carried out in order to evaluate genetic heterogeneity among isolates of Leishmania major in Iran...
