Abstract: The welding of dissimilar materials is one of the challenging issues in thefabrication industry to obtain required quality welds using fusion weldingmethods. However, some processes recently improved interface bondingwith low joint strength. Unfortunately, the major intermetallic compoundscould not alleviate from the joint interface. Alternatively, solid-statewelding methods revealed fewer intermetallics at the joint interface fordissimilar material... More

Abstract: The efficiency and irreversibility defined based on the second law ofthermodynamics provide a new path for heat exchangers design and makeperformance analysis more straightforward and elegant. The second lawof thermodynamics is applied in a Straight Microchannel Printed Circuitheat exchanger to determine the thermal performance of different shapes ofBoehmite Alumina compared to Al2O3 aluminum oxide. The... More

Abstract: Oman Sea is connecting belt between the Indian Ocean and PersianGulf. Because it strategic and environmental aim, presence of naturalradionuclide 226Ra, 232Th, 40K and 137Cs as man-made element is considered.Water samples were taken from 36 marine spots at the coastal strip fromHormoz canyon to Goatr seaport in the northern coast of Oman Sea.Correspondence analysis is...

Abstract: The hydrodynamic characteristics of bimetallic Ag/Cu and Co/Ag nanoparticles stabilized by chitosan were determined. The polydispersity indexand the diameter of nanoparticles were observed to decrease in contrast tothe original polymer during the creation of chitosan stabilized bimetallicnanoparticles, decreasing from 0.342 to 0.12±0.04 and 2.5 micron to 180nm, respectively. However, the diffusion coefficient of chitosan was... More
