In the metal cutting process, the friction and wear behavior between the cutting tool and machined surface is the most important factor that affects the surface quality and the service life of the cutter. The irregular pore structure of porous titanium alloy has changed its mechanical properties and the processing technology. The friction and wear mechanism of the cutting tool and the machined ...

nowadays network-on-chips is used instead of system-on-chips for better performance. this paper presents a new algorithm to find a shorter path, and shows that genetic algorithm is a potential technique for solving routing problem for mesh topology in on-chip-network.

In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18  o C for 6 months) were determined.  The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P < 0.05). Pre-frying  process resulted in a decrease in all fatty acid...

babbitt is a white silvery alloy that composed of tin, lead, copper and antimony. this alloy is the most current bearing alloy in industrial applications. the characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. the target of this study is investigation on the effects of alloy elements on wearing and micro-struct...

peppermint (mentha piperita l.) from lamiaceae family is one of the most important medicinal plants, used in food, sanitary and cosmetic industries. a field experiment was carried out in ferdowsi university of mashhad in 2010-2011 to evaluate the effects of three irrigation levels (100, 80 and 60 percent of water requirements calculated by evaporation pan class a) and two mulch types (black pla...

Background & Aim: Chemicals antioxidants and lipid oxidation products are known as cancer-causing factors in food systems. In this study, the effect of essential oil from Heracleum lasiopetalum fruits on lipid oxidation and physicochemical properties of potato chips in comparison with commercial antioxidant has been investigated. Experimental: The essential oil of H. lasiopetalum extracted usin...
