The effects of two mineral and two organic acids, four organic solvents (methanol, ethanol, 2-propano and acetone) and three inorganic metal salts in combination with temperature regimes 0 and 22C on the yield and resolubility of potato tuber proteins were studied. Using acids, the yield of precipitated protein ranged from 22.3% (citric acid, 0C) to 54.5% (acetic acid, 22C) of total protein; ho...

Two trawl surveys in the Northeastern Aegean Sea, conducted in 1997 and 2007 yielded a catch composition which, when re-expressed through the new concept of ‘mean temperature of the catch’ (MTC) yielded an MTC increase of 0.25 0C per decade, which is higher of the global MTC increase rate between 1970 and 2006, but slightly lower than the observed temperature increase in the Northeastern Aegean...

A research was conducted on the eff ect of heat treatments on the heating and cooling of the ‘Idared’ apple fruit. Th e heat treatment was performed as hot water dip (HWD), where fruit were dipped into water at 50 °C, for two, four and six minutes (HWD 500C 2’, HWD 500C 4’ and HWD 500C 6’, respectively). Th e aim of the study was to determine the eff ect of heat treatments on the warming and co...

The typical user environment load spectrum varies significantly between different electronic applications but changes in temperature are involved in nearly all of them. Owing to the increasing number of integrated high-performance functions, smartphones and handheld computers, for example, can experience significant changes in temperature during normal operation. The changes in temperature are ...

The purpose of this study is to analyze the quality optical properties such as energy band gap thin layer tin oxide doped with aluminum, fluorine, indium, aluminum-fluorine, aluminum-indium, and aluminum-fluorine-indium. was synthesized using sol-gel spin coating method. ratio basic ingredients doping used in 95:5% 85:15%. that has been formed then heated at a temperature 100 200 0C. results an...

The complete oxidation of n-Hexane and iso-Octane was studied individually in a fixed bed tubular flow reactor over CuO-CeO2 catalysts synthesized via four different methods namely urea-nitrate combustion method, urea gelation/co-precipitation method, citric acid sol-gel method and co-impregnation method. Laser diffraction was employed in catalysts characterization. The results obtained from th...
