understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. the lorestan basin is one of the most important hydrocarbon basins of iran, and it includes various oil-prone potential source rocks and reservoir rocks. previous geochemical studies of the basin were n...

Background: Lactobacilli are among the most important known probiotic species, and efforts underway to isolate them from various sources. The beneficial effect of probiotics on health is main reason for their wide use in dairy products, including yogurt. This research was conducted identify Lactobacillus species present traditional Iranian Methods: Thirty samples yogurt were collected different...

background and objectives: bitter melon is one of the anti-cancer medicinal plants that it’s wide level in vitro propagation and anti-cancer material production was necessary. different factors such as genotype, selected explants’ type and it`s preparation conditions influenced regeneration content. plant growth regulator`s effect on callogenesis and indirect regeneration from parangipetai indi...

The lentil (Lens culinaris Medik.) is an important cool-season crop and a valuable source of dietary protein and ranks seventh among grain legumes. Genotype by environment (GE) interaction is considered to be among the major factors limiting the efficiency of breeding programs. Eight improved lentil genotypes from the International Centre for Agricultural Research in the Dry Areas (ICARDA), one...

an oil and gas well cementing in gachsaran formation, where sustained annular pressure has been reported in many wells, presents a big challenge in maroon field. the main challenges are preventing gas migration and achieving zonal isolation using a competent cement sealant system which is able to withstand downhole stresses and high temperatures during production cycles. unlike conventional cem...

Abstract Recent research proclivity is about supplying water for drinking, urban and industrial applications which recognized as one of the most significant challenges that threaten humanity. Giving its simplicity high efficient yield, membrane technology has been preferred compared to other separation technologies wastewater treatment. In present research, KIT-6 (KIT: Korea Advanced Institute ...

This paper presents the yields and several stability parameters of additive main effects and multiplicative interactions (AMMI) model in ten improved lentil genotypes which tested in very diverse environmental conditions in Iran. The F-Gollob indicated that first three interaction principle component analysis (IPCA) axis of AMMI model was significant while cross validation procedure through RMS...

A rock failure criterion is very important for prediction of the ultimate strength in rock mechanics and geotechnics; it is determined for rock mechanics studies in mining, civil, and oil wellborn drilling operations. Also shales are among the most difficult to treat formations. Therefore, in this research work, using the artificial neural network (ANN), a model was built to predict the ultimat...
