To use soil hydrology processe (SHP) models, which have increasingly extended during the last years, comprehensive knowledge about these models and their modeling approaches seems to be necessary. The modeling approaches can be categorized as either classical or non-classical. Classical approaches mainly model the SHP through solving the general unsaturated flow (Richards) equation, numerically...

Background & Aims: Despite recent progresses in cancer treatment, the oral cancer is still one of ten most common causes of death because of late diagnosis. Considering the role of cultural and geographical factors in oral cancer prevalence, epidemiological studies are of great importance. Many investigations have reported evidence of an increasing incidence in oral cancers during recent years....
The relationship between institutions and economic growth is one of the main issues in economic development debates and has been considered empirically in recent years. Hence, the main purpose of this paper is to investigate the effects of institutions and recourses management improvement on economic growth in MENA countries during the period of 1996-2018. For achieving this, the econometric mo...
Background and Aims: Avian infectious bronchitis (IB) has prevalent in the most chicken farms during recent years, in spite of the IB vaccination program which has been widely performed in Iran. To better understand the molecular epidemiology of IBV in Iran, the full length sequences of S1 gene of Iranian QX IBVs were determined and phylogenetic analysis was done using some sequences of IBV. M...
