background and objective: today, opioids are used to control and relieve acute and chronic pain. however, the incidence of both tolerance and dependence phenomena for these drugs is a major problem. so, in this study, the combination effect of haloperidol and methadone on the acquisition and expression of morphine dependence and tolerance was examined.    materials and methods: ninety-eight mic...

Sweat absorption is investigated using the subjective and objective methods. The subjective investigation analyses the physiological responses of male and female volunteers wearing two kinds of textile fabrics (cotton and polyester) during certain physical activity. The subjects were exposed to the different conditions of ambient temperature (23, 26, 29 and 32 degrees C) and constant relative h...

A simple model of a portfolio allocation between mature and emerging markets is specified. The representative-agent, rational expectations version of the model has an unlimited number of equilibria, providing no reason to expect that heterogeneous agents would all coordinate on one or another equilibrium. Therefore, the model is simulated with heterogeneous expectations based on ex post returns...

BACKGROUND Spontaneous breathing trials (SBTs) are a very important test in the weaning process. The trial involves evaluation of multiple objective and subjective variables. These characteristics could lead to variability in interpreting outcomes with important clinical implications. We aimed to measure the inter-observer agreement between respiratory therapists when analyzing SBT outcomes. ...

The article shows that the current level of physiology does not disclose biological mechanisms organism transition from one range to adapt a higher with an increase in regular forces stimulus above sub-extreme. A new trend adaptation - proqredient adaptation, explains mechanism increasing tolerance organism, dependence on psychoactive substances (PAS ). It is scientifically proved, dependences ...

the time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. it is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. the phase dependence of the atom-field entanglement is...
