While some physical disciplines such as classical mechanics and electrodynamics underwent profound changes with the birth of quantum mechanics and relativity theory the Laws of thermodynamics and statistical mechanics per se proved impressively robust over the last century. The main reason being that the formulation of statistical mechanics rests on few pillars only, such as ergodic theory, ens...

The present work evaluates the anthocyanin degradation in blueberry pulp after thermal treatment using ohmic and conventional heating. The ohmic heating technology was studied using a rotatable central composite design, and the variables studied were voltage and solids content. The anthocyanin content of the samples was determined using HPLC. The results show that degradation increased with bot...

The electrical and structural properties of Hf/Al/Ni/Au (20/100/25/50 nm) ohmic contact to n-GaN are reported in this study. Specific contact resistivities of Hf/Al/Ni/Au based contacts have been investigated as a function of annealing temperature and achieve the lowest value of 1.09×10 Ω·cm after annealing at 650 C in vacuum. A detailed mechanism of ohmic contact formation is discussed. By usi...

The placement of a magnetic monopole into an electrically-neutral chiral plasma with non-zero axial density results in electric polarization the matter. current produced by effect is balanced charge diffusion and Ohmic dissipation, which generates non-trivial distribution. In turn, latter induces separation chiralities along field due to effect. We find stationary states such system, vanishing ...

The present paper deals with the effects of Ohmic dissipative Casson fluid flow over a stretching sheet in the presence of aligned magnetic field. The present phenomenon also includes the interaction of thermal radiation and velocity slip. The governing boundary layer equations are transformed into a set of ordinary differential equations using the similarity transformations. The dimensionless ...

Abstract The role of nonideal magnetohydrodynamics has been proven critical during the formation protoplanetary disks, particularly in regulating their sizes. We provide a simple model to predict disk size under interplay among ambipolar diffusion, Hall effect, and ohmic dissipation. predicts small around 20 au that depends only sublinearly on parameters, for wide range initial conditions subso...

In recent years, the world’s food industry has focused increasing attention on electrical techniques of food processing. Ohmic heating is one of these techniques that can be considered as a high temperature short time and a purely bulk heating method, having potential applications in processes such as blanching, evaporation and pasteurization in the food industry. However such technology would ...

Ohmic heating is an alternative fast heating technique for food products, which takes its name from Ohm's law. The basic principle of ohmic heating is the conversion of electrical energy into heat, resulting in internal energy generation. In this study, an experimental ohmic heating unit was designed and fabricated. Four kinds of liquid food materials (tap water, fruit-vegetable juice, yogurt a...

We derive hydrodynamic equations for systems not in local thermodynamic equilibrium, that is, where the local stationary measures are "non-Gibbsian" and do not satisfy detailed balance with respect to the microscopic dynamics. As a main example we consider the driven diffusive systems (DDS), such as electrical conductors in an applied field with diffusion of charge carriers. In such systems, th...
