A review is given for
the state of the art and future development of the geothermal
power engineering. Different diagrams of GeoPP are shown for different levels
of geofluid temperature. A special focus is made on challenges for
petrothermal power production. The huge amount of heat from petrothermal
resources can be harnessed through creating geothermal circulation systems
within the dry rocks. Estimates for system lifetime and heat production
capacity of circulation systems are given for different flow rates of
coolant.
The results of study of evaporation of water droplets
and NaCl salt solution from
a solid substrate made of anodized aluminum are presented in this paper.
The experiment provides the parameters describing the droplet
profile: contact spot diameter, contact angle, and droplet
height. The specific rate of evaporation was calculated from
the experimental data. The water droplets or brine droplets with
concentration up to 9.1 % demonstrate evaporation with the pinning mode for the contact
line. When the salt concentration in the brine is taken up
to 16.7 %, the droplet spreading mode was observed. Two stages
of droplet evaporation are distinguished as a function of phase transition
rate.
Results of numerical
simulation of heat and mass transfer in a laminar flow of three-component
gas at adiabatic evaporation of binary solutions from a flat plate are
presented. The studies were carried out for the perfect solution
of ethanol/methanol and zeotrope solutions of water/acetone, benzene/acetone,
and ethanol/acetone. The liquid-vapor equilibrium
is described by the Raoult law for the ideal solution and
Carlson–Colburn model for real solutions. The effect of gas temperature and liquid composition
on the heat and diffusion flows, and temperature of vapor-gas mixture
at the interface is analyzed. The formula for calculating
the temperature of the evaporation surface for the binary liquid
mixtures using the similarity of heat and mass transfer was proposed. Data
of numerical simulations are in a good agreement with the results of
calculations based on the proposed dependence for all examined liquid
mixtures in the considered range of temperatures and pressures.

Subsection: Problems of logic and methodology of science
In the course of the transformation of a scientific theory, there are changes that require unification and standardization of concepts, methods and procedures. Usually, the unification is nesessary at the stage of a paradigm formation when one of the competing schools begins to dominate while the other ones have to conform to it. During the unification, the theory undergoes changing, systematization and axiomatization, the diversity of statements is reduced to basic postulates. A unified theory gets a number of advantages including its increased flexibility and expanded area of its application also there are some disadvantages, one of them is the growth of a theory vulnerability because criticism aimed at the foundation of a theory weaken its state. We the last statement illustrate by an example taken from the history of mathematics. Disadvantages of the unification appear in science applications to practice as well, we illustrate it by examples too.

The paper presents a review of existing types of basic objects in physical theories, such as a material point, an elementary particle (virtual particle), quark, a fundamental string. Fundamental objects are considered in the historical perspective. It is shown that these objects, first, may be classified as formal, physical and hypothetical; secondly, they have a different ontological status. In view of this, a unified (consistent) description of reality is based on introduction of modalities into ontology which results in a model of polyontic reality (the idea of information capacity of mathematical spaces and that of a nongeocentric world comprise a concrete realization of this model).
It can be argued that if we commit ourselves to classical realism and classical logic we are forced to adopt an Everettian interpretation of quantum mechanics. But we cannot adopt it without substantial philosophical and physical qualifications. Nevetheles the classical metaphysical realism can be modified. We suggest an interpretation of quantum mechanics within a Wittgensteinian contextualiste non-metaphysical realism, which is indeed a demystified version of the Everett interpretation. The quantum theory is a Wittgensteinian rule. The “gap” between this rule and a concrete result of measurement is closed pragmatically (the measurement problem is dissolved). The Everettian branches-worlds are possible (not actual) applications of the theory-rule. The suggested deduction of the Born rule from the deterministic part of quantum mechanics, the most general principles of rationality and the symmetry principles, in our view, means that in a sense the Born rule is implicit in the formalism of quantum mechanics taken in its application. A complicated theory of the Everettian interpretation of quantum mechanics, developed by David Wallace, is the price to pay for refusing to modify the doctrine of metaphysical realism.

The paper analyses specific aspects of geological research. It is possible to connect them with using hermeneutical and historical procedures that extends and adds classical ideas about natural-scientific cognition. The theoretical basis of the paper is the research work of American scientist R. Frodeman. Geological cognition in a field investigation is a similar to text interpretation. There is no any prefabricated geological outcrop in a laboratory. Geologist has to choose substantial object for research by himself basing on knowledge. Geological outcrop is clearer in a general geological environment of region, area. In other words, the scientist is consistent with surrounding context. This approach leads to affirmation that geologist has two or more has several types of interpretation. Therefore, every geologist can make different conclusions. It is significant to admit that experiment cannot find any solution about genesis of geological solids. Because geological solids has being forming during millions years in a generous area. Chemical and physical experiments are just an element of interpretation or “reading” of the geological conditions in an area, which defines the properties of minerals, rock. On the assumption of this theory, the geology is a science, which has an object of investigation as the natural world, and at the same time uses methods of humanitarian knowledge including hermeneutic and historical procedures.
The article opens a series of studies dedicated to ancient meteorology. I discuss the method and content of Pseudo-Theophrastus’ “On weather signs” and translate a short treatise “On the location and names of the winds”, traditionally included in the Corpus Aristotelicum. The treatise is translated into the Russian for the first time. We see that the unknown author tries to correlate the theoretical wind diagram with the empirical data, and the picture, which appears as a result, significantly differs from the theoretical scheme developed in Aristotle’s Meteorology. On the other hand, his approach is more practical since he tries to take account of the local condition. After all, even Aristotle admits that his simple scheme is not exact and allows adjustment to specific geographic places.

The paper discusses if it is possible to justify the assumption of the existence of other minds in terms of common sense as G.E. Moore understands it in his article «A Defence of Common Sense».
This article suggests a new scientometric index that takes into account not taken into account in the calculation of citation of the classical h-index - Hirsch index+ developed the formula for finding the index by table to find the h-index from 1 to 20. The h-index+ can be used for internal monitoring of scientific productivity of a scientist in any scientific or higher educational institution. The proposed index allows you to more finely rank the growth of the team members, regardless of age and past scientific achievements.
