the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure          n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...

background: with regard to the high prevalence of schizophrenia, research on brain structural changes in this disease has been one of the interesting issues among the medical scientists. in this research, brain mri findings of schizophrenic patients have been compared with non-schizophrenic ones. methods: this study was an analytic-comparative one in which two groups of schizophrenic and non-sc...

This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...

Background Transient tachypnea of the newborn (TTN) is one of the most common neonatal respiratory disease and its symptoms usually begins in the first few hours after birth. The volume of fluid intake according to the neonate's conditions varies. We aimed to compare the restricted fluids volume with standard fluids volume in treatment of neonates with TTN. Materials and Methods: This clinical ...
