abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...

This study evaluated the status of scientific products of Ilam University of Medical Sciences, Ilam, Iran, quantitatively and qualitatively from 2001 to 2018 in the Scopus Citation Database. Materials & Methods: Quantitative indicators, such as the H-index (...
the present paper discusses the priority of cognitive processes over language production of the speaker, based on mulla sadra’s philosophy of language. in this regard, the conditions of perceiving knowledge as well as the process of language production of the speaker are propounded. mulla sadra believes that knowledge is perceived through a process in which human soul is an active agent rather ...
This study emphasizes the development of a flexible inventory system considering rework requirements on imperfect and defective items. work has considered items could be sold at lower price in market as compared to perfect The developed model Weibull deterioration inflation balance same amount future due its potential earning capacity. And demand's function depends well level because large pile...
previous studies had shown that sub-inhibitory concentrations of silver sulphadiazine (agsd) stimulated the production of toxic shock syndrome toxin-1 in certain strains (responder strains) of staphylococcus aureus and that protease production was also affected. no changes were detected in other strains (non-responders). extracellular proteins from eleven responder and non-responder strains gro...
nanotechnology has the potential to introduce revolutionary changes to several areas of oil and gasindustry such as exploration, production, enhanced oil recovery, and refining. in this paper, the effectof different concentrations of fe2o3 nanoparticles as a catalyst on the heavy oil viscosity at varioustemperatures is studied. furthermore, the effect of a mixture of fe2o3 nanoparticles and ste...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Deterioration of reproductive traits with age is observed in an increasing number of species. Although such deterioration is often attributed to reproductive senescence, a within-individual decline in reproductive success with age, few studies on wild animals have focused on direct fitness measures while accounting for selective disappearance and terminal effects, and to our knowledge none have...
