background: the h9n2 subtype of avian influenzaviruses (aivs) has been isolated in multiple avian species inmany european, asian, african and american countries. sincethe first outbreak of h9n2 virus in iran in 1998, this virus haswidely circulated throughout the country, resulting in majoreconomic losses in chicken flocks. several amino acids in thevirus ribonucleoprotein (rnp) complex includi...

binders are of prime importance in the agglomeration of iron ore concentrates. in this research, strength and density of briquette produced from the magnetite concentrate of gol-e-gohar were investigated using different binders at various applied pressures. the results showed that peridor was the most effective binder relative to bentonite and lime. for all types of binders, the increase in bin...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

Machine translation (MT) post-editing is now a popular practice in the translation industry. It has been shown to allow translations to be produced at lower cost without a decrease in quality. The post-editing of automatic translations can provide useful information for MT researchers and developers to evaluate translations and systems. We describe a standalone tool that has two main purposes: ...

theoretically speaking, ict is a new concept in enterprise architecture which can be studied in hrm and hr architecture issues. due to contextual variables carrying diverse variation and importance levels, designing an e-readiness framework of hr architecture is a complex issue. therefore, this idea is considered in iranian oil and gas industry to be piloted. framework of ict conceptual model d...

Bovine viral diarrhea virus (BVDV) is an economically important pathogen of the livestock industry worldwide. BVDV is classified into cytopathic (cp) and noncytopathic (ncp), depending on its effects on cultured cells. BVDV is known to alter the host’s immune response. Of this, major histocompatibility complex (MHC) class II molecules play a central role in the development and function of the i...
