The novel cannabinoid CB1 receptor neutral antagonist AM4113 suppresses ood intake and food-reinforced behavior but does not induce signs of nausea in rats
PublicationPrzeprowadzone badania biochemiczne wykazują, że związek AM4113 wiąże się z receptorem kanabinoidowym CB1, ale nie wykazuje właściwości odwrotnego agonisty (między innymi nie wpływa na powstawanie cyklicznego AMP). W testach na swobodne przemieszczanie się szczurów i znieczulenie związek AM4113 osłabia wpływ agonisty AM411 na receptor CB1. AM4113 wpływa na zachowanie szczurów związane z karmieniem oraz powoduje spadek łaknienia...

Systems, environments, and soliton rate equations: A non-Kolmogorovian framework for population dynamics
PublicationSoliton rate equations are based on non-Kolmogorovian models of probability and naturally include autocatalytic processes. The formalism is not widely known but has great unexplored potential for applications to systems interacting with environments.

Heat transfer intensification by jet impingement – numerical analysis using RANS approach
PublicationJet impingement is a method of the heat transfer enhancement applied in the engineering systems. The idea is to generate fast-flow fluid jet which impinge on the heated (or cooled) surface, causing significantly higher heat transfer rate. Although some flat surface jet impingement cases are described in the literature, the validated data is still limited. The reason is coming from the fact, that these flows are hydrodynamically...

Annihilation rates of low-energy positron scattering from simple diatomic molecules
PublicationWe discuss the calculations of Zeff coefficients for a series of diatomic molecules over the range of energies below the positronium formation. During the development of a general code for polyatomic, nonlinear molecules colliding with positrons, it was discovered that the earlier one, employed only for diatomic molecules, had an error. The error is corrected and the corrected results are presented here. We also discuss a way of...
