Solids can be cooled by driving impurity ions with lasers, allowing them to transfer heat from the lattice phonons to the electromagnetic surroundings.This exemplifies a quantum thermal machine, which uses a quantum system as a working medium to transfer heat between reservoirs.We review the derivation of the Bloch-Redfield equation for a quantum s
In the conditions of the knowledge economy, the most important source of competitive advantages of the organization is human capital.The human capital development is based on the relevant management culture to provide proper material and technical prerequisites for motivating both high activity culture standards and productive performance.Hence eff
Background and Aim Gentamicin antibiotic has some side effects such as nephrotoxicity.The aim of this Clothing study was to evaluate the post-treatment effects of using hydroethanolic extract of Origanum Vulgare (OV) on nephrotoxicity caused by gentamicin.Methods & Materials In this study, 32 male Wistar rats were divided into four groups of contro
Levamisole is effectively used in steroid-dependent nephrotic syndrome and the more frequent side effects reported are cytopenia and liver enzymes alterations.Several studies have demonstrated that this drug can induce high titers of circulating perinuclear antineutrophil cytoplasmic autoantibodies (ANCA) and vasculitis, most of them occurring in t
General patterns of forest dynamics and productivity in the Andes Mountains are poorly characterized.Here we present the first large-scale study of Andean forest dynamics using a set of 63 permanent forest plots assembled over the past two decades.In the North-Central Andes tree turnover (mortality and recruitment) and tree growth declined with inc
