Mechanisms of folate losses during processing: Diffusion vs. heat degradation

Isomerisation and degradation of lycopene during heat processing in simulated food system

The degradation and/or isomerisation of lycopene have an important influence on its bioavailability and bioactivities. Existing studies have shown that the configuration profiles and stability of lycopene will be changed because of heat processing, but the relationship between the structure conversion of lycopene and the intensity of heat treatment is yet to be further studied. To simplify the ...

Modeling of Heat Losses Within Combustion Chamber of Diesel Engines

The cylinder working fluid mean temperature, rate of heat fluxes to combustion chamber and temperature distribution on combustion chamber surface will be calculated in this research. By simulating thermodynamic cycle of engine, temperature distribution of combustion chamber will be calculated by the Crank-Nicolson method. An implicit finite difference method was used in this code. Special treat...

Heat accumulation during pulsed laser materials processing.

Laser materials processing with ultra-short pulses allows very precise and high quality results with a minimum extent of the thermally affected zone. However, with increasing average laser power and repetition rates the so-called heat accumulation effect becomes a considerable issue. The following discussion presents a comprehensive analytical treatment of multi-pulse processing and reveals the...
