The Ohmic heating rate of a food is highly influenced by its electrical conductivity. In this study, electrical conductivities, colour changes and system performance of liquid whole egg, white egg and yolk were determined on a laboratory scale static Ohmic heater by applying 30 V/cm voltage gradient. The samples were heated from room temperature through to pasteurization temperature (19 – 60°C)...

Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...

introduction: previous studies indicate that exercise influences cognitive function. nevertheless, considering that exercise in animal study can be voluntary, or forced, effects of exercise (specially forced exercise) on learning and memory abides as a matter of controversy. the present study aimed to investigate the effects of treadmill exercise on ltp in the dentate gyrus of rats. methods: th...

the aim of this study was to investigate the stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. the volatile constituents from the aerial parts of stachys turcomanica growing wild in iran were obtained by hydrodistillation and analyzed by gc and gc-ms. in the gc-ms analysis, forty-six components representing 81.1% of the oil were identifie...

objective: citrinin is a mycotoxin produced by several species of the genera aspergillus and penicillium and occurs mainly in food products and animal feed. some scientific reports show a link between citrinin and nephrotoxic and possibly a carcinogenic effect for humans. methods: samples collected by settling plates,in northern iran and pure culture isolation performed till the toxin measureme...

purpose to translate long form, interview-administered international physical activity questionnaire (ipaq) from english to persian and evaluate its validity, reliability and reproducibility. methods a forward-backward translation procedure was followed to develop the persian version of the ipaq. a total of 218 respondents (53.7% women, aged 22–76 yr) completed the persian version in tehran, ir...
