The electron-phonon interaction is of central importance for the electrical and thermal properties of solids, and its influence on superconductivity, colossal magnetoresistance and other many-body phenomena in correlated-electron materials is the subject of intense research at present. However, the non-local nature of the interactions between valence(More)
The objective of this study was to dry sweet liquid whey using drum dryer and to utilize the whey powder in French-type bread and cookies as a sugar substitute. The sweet whey powder was characterized chemically for ash, moisture, water activity, protein, salt, acidity and lactose contents. Optimization parameters including drying temperature, drum speed(More)
A low-cost experiment, feasible without the use of laboratory-grade atmospheric chamber and optical spectral analyzer, was designed to experimentally evaluate the influence of fog and smoke on free-space optical systems. Low-visibility conditions were simulated using an artificial fog machine and smoke flares in a 50 m PVC corridor with several(More)
