Color Changes Kinetics and Heat Transfer during Deep Fat Frying of Garlic Slice
Heat and mass transfer phenomena that take place during frying cause physicochemical changes, which affect the colour and surface of the fried products. The effect of frying temperature on the colour changes and heat transfer during deep fat frying of garlic has been investigated. The colour scale parameters redness (a*), yellowness (b*) and lightness (L*), and color change intensity (∆E) were ...
متن کاملGross thermodynamics of heat engines in deep interior of Earth.
From the gross conservation laws of thermodynamics in a convecting material we derive a bound on the ratio of the rate of production of mechanical or magnetic energy to the rate of internal radioactive heating which drives the convection. Our bound for this "efficiency" depends on the temperatures in the material, and can exceed unity. Whether the bound can be attained by "efficiencies" in real...
متن کاملHeat exhaustion in a deep underground metalliferous mine.
OBJECTIVES To examine the incidence, clinical state, personal risk factors, haematology, and biochemistry of heat exhaustion occurring at a deep underground metalliferous mine. To describe the underground thermal conditions associated with the occurrence of heat exhaustion. METHODS A 1 year prospective case series of acute heat exhaustion was undertaken. A history was obtained with a structur...
متن کاملInvestigating the Effect of the Deep Cryogenic Heat Treatment on the Mechanical Properties and Corrosion Behavior of 1.2080 Tool Steel
Deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the final tempering treatment to enhance the wear resistance and hardness of the steels. In this study, the effects of the deep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studied using the wear testing machine and polarization and impeda...
متن کاملthe comparison of the effect of deep and superficial heat on healthy ankle joint position sense
background: heat therapy is one of the natural treatments that can affect the information transferred by the proprioceptive receptors. heat has an effect on the conduction velocity of peripheral nerves, but the exact effect of two kinds of deep and superficial heat on the joint position sense is not known clearly. the present study aimed to compare the effect of deep and superficial heat on ank...
