We extend the quantum theory of dissipation in the context of system-reservoir model, where the reservoir in question is kept in a nonequilibrium condition. Based on a systematic separation of time scales involved in the dynamics, appropriate generalizations of the fluctuationdissipation and Einstein’s relations have been pointed out. We show that the Wigner-Weisskopf decay of the system mode r...

Deposits can affect the in-furnace wall surface temperature in a Kraft recovery furnace. In CFD (Computational Fluid Dynamics) models of the Kraft recovery furnace, the wall surface temperature is frequently used as the heat-transfer boundary condition. Therefore, the effect of deposits must be taken into account in CFD models. In this work, CFD simulations of a Kraft recovery furnace were perf...

The efficiency of the application of high-emissivity coatings on the furnace walls in steam cracking technology can only be evaluated on the asis of a description of radiative heat transfer distinguishing between the frequency bands. To this end, a non-grey gas radiation model based on he exponential wide band model (EWBM) has been developed and applied in the context of three-dimensional CFD s...

conclusions it is suggested that the training of nonpharmacological methods to improve sleep quality such as reflexology and foot bath be included in the elderly health programs. in addition, it is recommended that the impact of these interventions on subjective sleep quality using polysomnographic recordings be explored in future research. background sleep disorders are common mental disorders...

Penetration of electrolytes through the human skin was measured in healthy volunteers and in psoriatic patients after bathing in the Dead-Sea or in simulated bath-salt solutions. Significant increases in the levels of serum Br, Rb, Ca and Zn were noticed only in the psoriatic patients after daily bathing in the Dead-Sea for a 4-week regimen. Guinea-pigs "bathed" in simulated Dead-Sea bath-salt ...

ALVARADO, RONALD H., AND ANNE MOODY. Sodium and chloride transport in tadpoles of the bullfrog Rana catesbeiana. Am. J. Physiol. 218(5): %1510-1516. 1970.-Unfed bullfrog tadpoles actively transport sodium and chloride ions into their body fluids from a dilute bath. The rate of exchange is about 1 pmole/lO g-hr for each ion. This can be enhanced by salt depletion. Sodium and chloride can be tran...

New or novel psychoactive substances (NPS) are the most recent forms of designer drugs. These materials are sold as “bath salt” mixtures or fertilizers through the internet and in head shops worldwide [1]. Of course there are no proven medical purpose of these compounds which mostly contain synthetic cathiones or piperazines. The form is usually powder or bath salt like crystalline which are in...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

public bathes have much importance in islamic cities, after the most significant structures like mosques and schools. there are a number of factors affecting the construction of bathes among which temperature regulation, humidity, access path, location in the urban texture, watercourses, and construction of exit paths are the most important. this study tries to make a comparative analysis of t...
