Quality strongly depends on good mechanical properties of any manufacturing material. Similarly, quality Tungsten Inert Gas (TIG) welding Duplex Stainless Steel (DSS) like percentage elongation, ultimate tensile strength etc. Better Percentage Elongation (PE) is produced using proper parameters and their values at the time TIG welding. In this study, has been done ASTM/UNS 2205 duplex stainless...

We report the transformation of a conventional composite material into multifunctional structure able to provide information about its structural integrity. A purposely positioned grid carbon fabric strips located within glass fibre laminate in alternating 0/90 configuration combined with ternary nanomodified epoxy matrix imparted health monitoring (SHM) topographic capabilities using impedance...

Ultrasonic-assisted extraction (UAE) using response surface methodology (RSM) was employed for the highly efficient of bioactive compounds such as polyphenols and antioxidants from cumin (Cuminum cyminum L.) seeds. A central composite design (CCD) consisting three variables five levels used to estimate significance each process variable in application UAE seed extraction. Process optimized were...

in order to study the effects of three operations of rangelands on the properties of vegetation in rangelands, this research was conducted in chaat gonbad, golestan province, iran in 2004. chaat area is located in 50 km of border road of dashlibroun to maravetappeh in north of attract river (border of iran and turkmenistan). the altitude is 70 m, annual rainfall is 170 mm and annual temperature...

heart disease - cardiovascular, cancer and obesity are the main causes of death and there are direct relationship between the consumption of high-fat foods and the incidence of these diseases. therefore the demand for low-fat food products and probiotics has been dramatically increased. in this study, the effect of different levels of three hydrocolloids (inulin, chitosan and xanthan) at three ...

in order to comply with stringent pollutant emissions regulations, a detailed analysis of the engine combustion and emission is required. in this field, computational tools like cfd and engine cycle simulation play a fundamental role. therefore, the goal of the present work is to simulate a high speed di diesel engine and study the combustion and major diesel engine emissions with more details,...
