An N-system with different units submitted to shock and wear is studied. The shocks cause damage and, eventually, simultaneous failures of several units. can also fail due internal failures. At random times, the system inspected, down are simultaneously replaced by identical ones. arrival governed a Markovian process. operational times interarrival between inspections follow phase-type distribu...

In-situ synthesis of Ti-incorporated MCM-41 nano catalyst was carried out by the hydrothermal method to prepare a mesoporous catalyst for the oxidative desulfurization reaction (ODS). Oxidative reaction of dibenzothiophene (DBT) as a heavy sulfur compound was evaluated in a solution of n-decane as a model of liquid fuel. The synthesized catalysts were characterized by XRD, FESEM, EDX, TEM, FTIR...

In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...

Oligo-Miocene Bagh-e-Khoshk granitoid stock is intruded into the Eocene volcanic rocks in the southeastern part of the Urumieh-Dukhtar Magmatic assemblage in Iran. The granitoids are mainly consisting of diorite, quartz diorite and granodioritic rock types. They are metaluminous to slightly peraluminous, medium to high K calc-alkaline, with SiO2 ranging from 50.2 to 66 wt.%. The majo...
