This article reflects the results of a theoretical understanding of the problem of spiritual-moral formation of personality. Relying on the method of theoretical analysis, we note the fact very long and sustained interest of representatives of various branches of anthropology to this issue. Fundamental research in this area was carried out by philosophers, culturologists, sociologists, the results of whose researches, from our point of view, can be regarded as a theoretical, methodological bases for the development of the problem of education of spirituality and morality of the individual from the standpoint of pedagogy. No of less important for the development of technological approaches to optimization of the process of spiritually-moral education of personality you are the works of psychologists. It was the psychologists, analyzing the essential characteristics of spirituality and morals in the first place, bind them with the attitude of the subject, both to the world and to ourselves; associate spirituality and morality as the cognitive and affective processes. The allocation of the spectrum of characteristics that reflect the essence of spirituality and morality of the individual, will allow, from our point of view, to optimize the process of developing technological approaches to solving this problem.

Abstract Lithium–sulfur (Li–S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li–S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li–S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li–S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li–S publications to find the shortcomings of Li–S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li–S batteries are discussed. Graphical Abstract

This book attempts to tell the person interested in fetal and neonatal mortality what to look for and how, in a relatively unknown field in medicine. Obviously in an area in which so little fundamental research has been done it is, as the authors state, a matter of personal opinion whether one can state the cause of death in any infant. With this humble point of view and with the basic information available in this book, the opportunity exists for making a rational approach to the problem.

Abstract Proper understanding of sorption behaviour of the materials is important from the point of view of fundamental research and technology as well for applied building technology. In this paper a simple method is presented for measuring water sorption capability of solid bodies. Moisture sorption and desorption measurements were carried out on soil samples by using climatic chamber. After drying the samples in a Venticell 111 type drying equipment they were treated with a Climacell 111 type climate chamber, where the relative humidity (RH) was varied from 40 to 83% at 22°C for different times (40, 80, 120 and 240 minutes). The samples reached the equilibrium moisture content after 120 minutes for sorption. The desorption isotherm measurements were carried out at 22°C for 80 minutes of exposure at constant RH. At this point hysteresis phenomenon was observed. Besides the moisture content figures the time evolution of the damping process is also presented in this paper.

Vapor explosions have been investigated both theoretically and experimentally for several decades, focusing either on the vapor film, or on mechanical aspects. Where the main interest for industry lies in the safety risks of such an event, fundamental research is focusing on all partial processes that occur during a vapor explosion. In this paper, vapor explosions are discussed from a heat transfer point of view. Generally accepted knowledge of heat transfer between hot surfaces and liquids is compared to early investigations regarding the origin of vapor explosions. Both steady state and transient models are discussed. The review of available literature suggests that vapor explosions trigger spontaneously by the collapse of the boiling film. Better understanding of the fundamental aspects of vapor explosions might give rise to future ideas on how to avoid them.

Obstruction of the lumen of the appendix is still considered to be the main cause of acute appendicitis (including feces), followed by the increased intraluminal pressure, the development of ischemia and mucosal hypoxia of the appendix, ulceration, violation of the mucous barrier and the development of necrosis. A sufficient number of scientific facts have been accumulated completely refuting this postulate. Current fundamental achievements in molecular biology, biochemistry, etc. did not become the basis for a clinical revision of the ancient well-established theories and concepts of the etiopathogenesis of many diseases in almost all medical specialties. Surgery isn’t an exception in this context. The review considers the etiopathogenesis of acute inflammation of the appendix from the current point of view of the hypothesis of epithelial-endothelial dysfunction and epithelial-endothelial distress syndrome, since it most fully characterizes the integration of the etiopathogenesis of almost all common diseases of organs with mucous membranes and the recent fundamental research their structures and functions. It is based on general and local factors of violation of the lymphoid apparatus and the integumentary epithelium barrier functions. Thus, this work presents a new concept of the etiopathogenesis of acute appendicitis, which in turn will allow the surgery of acute appendicitis to reach new levels of understanding.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

ABSTRACTThe mechanism by which a shepherd satellite exerts a confining torque on a ring is considered from the point of view of a single ring particle. It is still not clear how one might most meaningfully include damping effects and other collisional processes into this type of approach to the problem.
