Compact star-forming galaxies: relations between integrated characteristics of a starburst
Authors:   Taras Shevchenko National University of Kyiv, Izotova I.
Published: April 2022

We study a large sample of compact star-forming galaxies (CSFGs) from the Data Release 14 of the Sloan Digital Sky Survey. The sample includes about 30000 compact isolated galaxies with angular diameters about 6”–10” in the redshift range z = 0–1. The Hb emission lines with equivalent widths EW(Hβ) ³ 10 Å are observed in the spectra of all selected galaxies. Only star-forming galaxies without obvious signatures of an AGN and with well-detected [OIII]l4363 Å were included in the sample. We consider the relations between the extinction- and aperture-corrected star formation rate SFR(Hβ), specific star formation rate sSFR(Hβ) and their respective values, SFR0(Hβ) and sSFR0(Hβ), reduced to a zero starburst age, on the one hand, and the mass of young stellar population with the age < 10 Myr, the age of a starburst, and the oxygen abundance 12+logO/H in the interstellar medium of these galaxies, on the other hand. A tight and almost linear correlation is found between the star formation rate and the mass of the young stellar population, but a weak correlation is revealed between the star formation rate and oxygen abundance. It is shown that the specific star formation rates, with average values ásSFR(Hβ)ñ = 8.8 Gyr-1 and ásSFR0(Hβ)ñ = 28 Gyr-1, do not depend on the mass of the young stellar population and oxygen abundance and therefore are the universal characteristics of compact galaxies with active star formation.
Loss of angular momentum when the planet’s atmosphere leaks into space
Authors:   Taras Shevchenko National University of Kyiv, Parnovsky S.
Published: April 2022

In the case of a rotating planet the well-known Jeans mechanism of atmospheric leakage into space leads to a decrease not only in its mass, but also in the angular momentum. We found a constrain linking these losses. On its basis, it is shown that this mechanism could not significantly affect the duration of the Earth’s day and its accounting cannot smooth out the problems associated with the theory of the formation of the Moon during the so-called Giant impact, i.e. collision of the protoplanet Theia with the Earth.

Authors: Antonova N.V. , Naumtseva E.A.
Published: April 2022

The article analyzes the problem of coaching effectiveness in the framework of coaching psychology, which is the young developing discipline that focuses on the psychological mechanisms of coaching. Coaching as a helping practice has been actively developing during recent years, but its effectiveness is still under debate. The article analyzes various theoretical approaches to coaching and concludes that cognitive-behavioral coaching (CBC) has the most developed evidence-based methodology. The methods and approaches for assessing the coaching effectiveness both in organizations and in individual work are analyzed. A multilevel model for assessing the effectiveness of coaching “a clock tower model” is also described. It includes both objective and subjective methods of assessment, as well as “process oriented” and “result oriented” methodologies for assessing coaching. The conclusion about the need to increase the share of quantitative and objective methods for assessing the effectiveness of coaching is made.
Advanced Concepts of the Role of Social Factors in the Development of Internet Addiction Behavior in Children and Adolescents (Based on Foreign Studies)
Authors: Semenova N.B.
Published: April 2022

Objective. To analyze the currently available data on social risk factors and their influence on the IA development process and to evaluate possible prospects for further research in the field of Internet addiction behavior in children and adolescents.Background. The excessive Internet use among children and adolescents is known to be a serious public health problem, however, the influence factors and the mechanisms of Internet addiction (IA) remain largely unknown. The importance of social factors in the formation of addictive behavior is undeniable, and currently there seems to be an extremely little information of this kind of research. So far many mechanisms explaining the contribution of family and school factors to the development of IA have not been identified. The question remains open why, with the same conditions of upbringing, some adolescents develop IA, while others do not.Conclusions. The quality of family relationships and the school environment have a significant impact on the IA development process in young people, which is mediated through the development of certain character traits that either facilitate for social norms and rules to be acquired or encourage the addictive behavior. However, social factors of influence cannot be considered to be absolute. The presence in adolescents of such qualities as a high level of self-control and volitional self-regulation provide the resilience to the IA development process. The phenomenon of resilience is an extremely urgent but poorly studied area, which determines the prospects for further scientific research, including the problem of Internet addiction behavior in children and adolescents.
Features of Religiosity and Faith of Representatives of the “Information” and “New” Generations
Authors: Pishchik V.I. , Lobacheva A.O.
Published: April 2022

Objective. Comparison of the value bases of faith, objects of faith, belief in conspiracies, the level of religiosity among representatives of the “Information” and “New” generations.Background. If traditional values are destroyed, meaning is lost, there is an intergenerational gap, and religious institutions are in crisis, the problem of religious certainty for young generations arises. There is a lack of confidence in the younger generation, a gap between external and internal religiosity. The generational approach to the study of religiosity is poorly represented in research. It is highly relevant to study the features of religiosity and faith of representatives of generations in a transitive society.Study design. The study was conducted using a socio-psychological survey. The data were analyzed by factor analysis, methods for determining the significance of differences in indicators.Participants. Secondary school students (150 people, 53% girls and 47% boys from 14 to 17 years old) are the “New” generation; first-year university students aged 19 to 23 years (140 people, 50% girls and 50% boys) are the “Information” generation of Rostov-on-Don.Measurements. Method of measuring types of mentality; method of measuring values through fears; method of “Belief in a conspiracy”; scale of ranking objects of faith; questionnaire for measuring religiosity. The SPSS-20 application software package was used. to process the results.Results. In both groups, the innovative mentality prevails, archetypes are in the transition zone from tradition to innovation; the value of the “Mystical” is less pronounced in the “Information” generation; representatives of both generations believe more in miracles, God, Paradise and life after death; to a lesser extent — in UFOs, ghosts and witchcraft. Representatives of the “Information” generation believe more in political, food and pharmaceutical conspiracies. Representatives of the “New” generation believe more in information and food conspiracies. The “Information” generation believes that spirituality and faith are very important in life, but they do not adhere to any religious faith, they consider themselves spiritual. The degree of religiosity in both groups is weak, but prevails in the group of the “New” generation.Conclusions. There is a contradiction between the objects of faith, spirituality and religiosity. This indicates that the representatives of the studied generations have immature forms of religiosity.

Anti-erosion package-combined tilling and sowing machine for strip tillage on the slope
Authors: Samadalashvili A. G
Published: April 2022

The paper describes a highly productive resource-saving anti-erosion combined agricultural machine for strip tillage of eroded soils on the slopes. The machine treats only the strips intended for sowing of certain width (20-30 cm) and depth (15-25 cm) without overturning. The border strips are resting, and they are to be treated in the years to come. The machine performs 6-8 agricultural operations during one field day; its working organs are arranged in two packages on the single common frame. The working organs of first package (hanging knives, deep tiller blades, covering knife and harrow) perform the loosening of soil layer without its overturning. The working organs of second package (sowing machine and packing wheels) perform the sowing and packing of plowed strip. The machine is a three-row one. The row-width spacing is 70 cm; the overall operating width is 170 cm; the plowing depth is 15-25 cm; the operating rates are 7-9 km/h; the hourly efficiency is up to 1.5 ha/h. The package-combined machine can be aggregated with tractors of 1.4-3.0 drawbar category. Due to the formation of mini inundation canals and maximum retaining of stubble on soil surface, the moisture is preserved in the soil for a long period of time, that leads to the thickening of humus layer of soil, to retarding of development of erosion processes, and as a result to the increase in productivity. Since the output per shift of the proposed tilling and sowing machine is by 2-2.5 times higher than under tillage by means of commonly used plows, and the consumption of combustive and lubricating materials and environmental pollution by exhaust gases are by 2-2.5 times lower, the machine should be considered not only as energy and resource-saving, but as environment-oriented one.
