The pellets were sintered at 900 ° C for 15 h in gold sealed tubes. The structural transformations in the obtained oxyfluoride K(Nb0.8Mg0.2)O2.4F0.6 were checked by X-ray diffraction (XRD) from room temperature to 525 ° C.

Abstract — Kinetic studies were conducted on the process of the dissolution of non-ferrous metals with the use of sulfur-containing material as a source of leaching agent - sodium thiosulfate. It is shown that with increasing concentrations of sodium hydroxide in solution in the range of 0.1 - 1.0 M, copper recovery is increased from 21.5 to 46.2 %. As the temperature increases from 25 to 45 0 C, copper dissolution rate in the initial moment of the time increases, then over time this...

In this section, we examine cycles that use two-phase media as the working fluid. These can be combined with gas turbine cycles to provide combined cycles which have higher efficiency than either alone. They can also be used by themselves to provide power sources for both terrestrial and space applications. The topics to be covered are: i) Behavior of two-phase systems: equilibrium, pressure temperature relations ii) Carnot cycles with two-phase media iii) Rankine cycles iv) Combined cycles
Topics: Physics, Statistical Physics and Thermodynamics, Phase Transitions, Thermodynamics, Carnot Cycle,...

The purpose of this book is to acquaint the reader with the principal phenomena and most important laws of physics. The authors have tried to make the book as compact as possible, including only what is essential and omitting what is of secondary significance. For this reason the discussion nowhere aims at anything approaching completeness.

This article presents five text analyses produced with Perspective Text Analysis (PTA / Vertex), founded on the Action-action-Objective paradigm, which Immanuel Kant once proposed in theory and which today is operational. After a terminological discussion about style in writing, the term proposed is textual gait.

The present compilation includes four articles on various topics, each of which contains an exposition of the present state of art in the most interesting and timely problems of solid-state theory. The authors are physicists who have contributed significantly to this field of science. ... It goes without saying that the selection of material to illustrate the achievements in solid-state physics must inevitably be subjective. For the compilation does not hold works on superconductivity, a...

We will learn how elements of perturbation theory can be formulated e_ciently by staying �rmly within the framework of the �eld integral. In doing so, we will see how the �eld integral provides a method for identifying and exploring non-trivial reference ground states � �mean��elds�. A fusion of perturbative and mean��eldmethods will provide us with analytical machinery powerful enough to address a spectrum of rich applications.

This book is intended for readers taking up the study of thermo dynamics, statistical physics and kinetics. Accordingly, readers are assumed to have a knowledge of elementary physics, higher mathematics and quantum mechanics. The sections marked by asterisks require a deeper knowledge and can be omitted on the first reading. The book aims to gradually familiarize readers with methods used in thermodynamics, statistical physics and kinetics, to show how the concrete problems should be solved...
