The probable reasons for evolution of weld porosity and solidification cracking and the structure- property relationship in aluminium welds were investigated. Aluminium plates (1xxx series) were welded by Tungsten Inert Gas (TIG) welding process, 5356 filler metal was used and heat input was controlled by varying welding current (145A, 175A and 195A). The welded samples were examined under opti...

The tendency to consume food with lower sugar content and alternatively healthy foods and food products are rising. High levels of sugar in date syrup might be used as a good alternative to sugar in various food products. Iran is one of the main producers of date fruit and it is possible to produce foods with high nutritional values from date to replace high-sugar content food....

The morpholinium cation based ionic liquids are designed to evaluate the thermophysical, chemical reactivity, and biological activity. To estimate and design the bioactive ILs, propionate and trihalopropanoate were considered under theoretical study by Density Functional Theory (DFT). To make effect of halogens atom on anion, propionate, trifluro propionate, trichloro propionate, and tribromo p...

The Flavobacterium columnare heat shock protein (HSP) gene dnaJ* was isolated, cloned, expressed, and used as an antigen in a recombinant vaccine strategy for channel catfish Ictalurus punctatus. The F. columnare dnaJ* sequence was obtained from genomovars I and II and showed intraspecies variability. Recombinant protein was expressed and purified from Escherichia coli cultures and injected int...

in this research, fabrication of an in-situ composite via aluminothermic combustion synthesis in al–v2o5 system has been investigated. for this purpose, the mixed powders of al and v2o5 with molar ratio of 28 to 3 were ball milled and then compressed. differential thermal analysis was used to evaluate the temperatures of phase transitions. using the peak temperature of the reactions, the sample...

The effect of weld heat input on the formation of intermetallic compound (IMCs) layer during arc welding–brazing of aluminium and steel dissimilar alloys, was investigated through both finite element method (FEM) numerical simulations and experimental measurements. The results of FEM analysis as well as welding experiments indicated that increasing weld heat input increases the thickness of IMC...
