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...

recently, mixtures of clay-tire chips are used as construction material in civil engineering projects. with respect to the tending for using these materials, it is necessary to know their mechanical behavior. thereby, a number of undrained monotonic triaxial tests are carried out on the specimens of pure clay and clay-tire chip mixtures. mixed specimens prepared by mixing pure clay with 10%, 20...

in this paper, a novel method of producing bi-metallic alloy nanoparticles at low temperatures using hydrogen bombardment of thin films, deposited on glass substrates, is introduced. optical and morphological characteristics of the nanoparticles were extensively studied for various conditions of plasma treatment, such as plasma power density, temperature, duration of hydrogen bombardment, thick...

the openings of copper converter in sarcheshmeh copper complex in iranis made of a heat resisting austenitic steel (fe-25cr-12ni) and many failures have been reported. understanding the failure mechanism of the alloy helps to develop better alloys for similar complex environments. samples of as-cast alloy and those taken from failed ones were examined. optical microscopy (om), x-ray diffraction...

The small blind internal thread (SBIT) plays a very important role to firmly fastening some functional components on the cover of 3C electronic products. was made in hole using fluteless forming tap (FFT) without producing chips. However, four geometric parameters FFT (tool width (W), tooth root diameter (D2), front-end (Df), and angle (?)) will affect filling rate (f) minimum torque (T) tappin...
