Критична соціальна філософія освіти і перспективи демократичної інституалізації систем суспільства (Critical social philosophy of education and prospects for the institutionalization of democratic systems of society)
Розглядається модель «критичної соціальної філософії освіти», втілена в програми суспільного розвитку
і навчання, які перш за все покликані навчити людей провадити самостійне й оригінальне дослідження себе,
соціуму й системи знань. Водночас обґрунтовується, що ці моделі та програми не мають бути відірвані ані від
індивідуально-колективної системи моральних і соціальних цінностей, теоретико-прикладного навчання, ані
від подальшого застосування набутих цінностей, норм і навичок у повсякденному житті, науці чи на виробництві,
у сфері
усіх соціальних
інститутів (Consider a model of «critical social philosophy of education», as embodied in the programs of social development
and learning, which are primarily designed to teach people how to lead an independent and original research themselves,
society and knowledge systems. However, it is proved that the models and programs should not be cut off from any individual
and
the
collective
system
of
moral
and
social
values
,
theoretical and applied training, nor from further use of the
acquired values, norms and skills in everyday life, science, or in production, sphere of all social institutions. The critical
social philosophy of formation aspires to update the humanised maintenance and sense of formation not for introduction
of values of the industrial capital and high technologies, but, first of all, for radical democratisation of formation for the
purpose of achievement of the progressive purposes, that research that will promote development of the person, civilisation
and community, social justice and strengthening of democratic participation in all versions of a life.
Formation should be reconstructed to the decision of tasks of technical revolution, but at the same time we should recognise,
that
in
the
globalized
world
there
is
a
menacing
growing
inequality,
conflicts
and
dangers,
therefore,
to
make
formation
corresponding
to
a
modern
situation,
it
should
investigate
and
solve
and
these
problems.

as
it
and
representatives of modern critical social philosophy of formation and critical, radical pedagogics offer. Globalisation
and technological revolution should be used for radical reorganisation of formation and maintenance for representatives of
social philosophy of formation and radical pedagogics of educational conditions that they could offer the models of pedagogics

Though
also

also

Thus,
it

demand for new knowledge and reorganisation
of formation with the program
of its democratisation.
Comprehension of these lessons of global development is necessary as for theoretical judgement of today’s prospects
of a world progressive policy in whole and in an education sphere in particular, and for practical attempts to change
our world to the best in interests of the public majority
The biology of Simulium noelleri and Simulium dolini: morphological, ecological and molecular data
Molecular genetic research has revolutionized the taxonomy and systematics of the Simuliidae family. Simulium noelleri Friederichs, 1920 is a species of blackfly, common in the Holarctic, reported for 33 countries. In 1954, Topchiev recorded it in Ukraine for the first time. Simulium dolini Usova et Sukhomlin, 1989 has been recorded at the borders of Ukraine and Belarus. It was described for the first time by Usova and Sukhomlin in 1989 from the collection from the territory of Volyn region in 1985. Usova and Sukhomlin, Yankovsky, Adler state that S. noelleri and S. dolini are different species by the morphological characteristics that differ in all phases of development. Adults differ in the structure of the genital appendages, palps, the margin and shape of the face and forehead, the colour of the legs; the larva – in the pattern on the frontal capsule, the number of rays in the fans, mandibular teeth and the hypostoma, the structure of the hind organ of attachment; pupae – in the branching way of gills. Molecular data are becoming an increasingly important tool in insect taxonomy. Therefore, we had to check that these two closely related species also have genetic difference. The development of S. noelleri and S. dolini was studied in four small rivers of Volyn region, Ukraine (Chornohuzka, Konopelka, Putylivka, Omelyanivka) in the period from 2017 to 2019. During initial processing of insect samples, we used the standard protocols EPPO PM7/129. We obtained the nucleotide sequence of S. dolini. It was proved that the populations of S. noelleri and S. dolini from medium and small rivers of Volyn differ in biological, morphological, behavioural and genetic characteristics. Comparison of the species S. noelleri with the data of the GenBank confirms the identification of three distinct morphotypes from Volyn, Great Britain and Canada. As a result of the conducted researches, it was confirmed that two close species of S. dolini and S. noelleri from the noelleri species group differ in the structure of mitochondrial DNA, which confirms their independent taxonomic status. Additional studies comprising more individuals from larger areas of Europe are required to verify the taxonomic position of these two species
The Spatial-Kinematic Structure of the Region of Massive Star Formation S255N on Various Scales
The results of a detailed analysis of SMA, VLA, and IRAM observations of the
region of massive star formation S255N in CO(2---1), \nh, \nhh, \co and some
other lines is presented. Combining interferometer and single-dish data has
enabled a more detailed investigation of the gas kinematics in the moleclar
core on various spatial scales. There are no signs of rotation or isotropic
compression on the scale of the region as whole. The largest fragments of gas
(0.3 pc) are located near the boundary of the regions of ionized
hydrogen S255 and S257. Some smaller-scale fragments are associated with
protostellar clumps. The kinetic temperatures of these fragments lie in the
range 10---80 K. A circumstellar torus with inner radius R
8000 AU and outer radius R 12 000 AU has been detected around the clump
SMA1. The rotation profile indicates the existence of a central object with
mass 8.5/ sin 2 (i) M . SMA1 is resolved into two clumps,
SMA1---NE and SMA1---SE, whose temperatures are 150 K and 25
K, respectively. To all appearances, the torus is involved in the accretion of
surrounding gas onto the two protostellar clumps
Physical and mechanical properties and thermal protection efficiency of intumescent coatings
The new engineering technique for the experimental investigation of physical and mechanical characteristics of thermal protective intumescent coatings is offered. A mathematical model is proposed for predicting the thermal behavior of structures protected by coatings; the model is closed by the studied material characteristics. The heating of a metal plate under standard thermal loading conditions is modeled mathematically. The modeling results are in good agreement with bench test results for metal temperature under the coating. The proposed technique of studying physical and mechanical characteristics can be applied to identify and monitor the state of thermal protective intumescent coatings in the long-term operation
Multi-frequency Studies of Massive Cores with Complex Spatial and Kinematic Structures
Five regions of massive star formation have been observed in various
molecular lines in the frequency range GHz. The studied regions
possess dense cores, which host young stellar objects. The physical parameters
of the cores are estimated, including kinetic temperatures ( K),
sizes of the emitting regions ( pc), and virial masses (). Column densities and abundances of various molecules are
calculated in the local thermodynamical equilibrium approximation. The core in
99.982+4.17, associated with the weakest IRAS source, is characterized by
reduced molecular abundances. Molecular line widths decrease with increasing
distance from the core centers (). For b\ga 0.1~pc, the dependences
are close to power laws (), where varies from
to , depending on the object. In four cores, the
asymmetries of the optically thick HCN(1--0) and HCO(1--0) lines indicate
systematic motions along the line of sight: collapse in two cores and expansion
in two others. Approximate estimates of the accretion rates in the collapsing
cores indicate that the forming stars have masses exceeding the solar mass.Comment: 18 pages, 7 figures, 6 table
Simulating the Time Projection Chamber responses at the MPD detector using Generative Adversarial Networks
High energy physics experiments rely heavily on the detailed detector
simulation models in many tasks. Running these detailed models typically
requires a notable amount of the computing time available to the experiments.
In this work, we demonstrate a new approach to speed up the simulation of the
Time Projection Chamber tracker of the MPD experiment at the NICA accelerator
complex. Our method is based on a Generative Adversarial Network - a deep
learning technique allowing for implicit estimation of the population
distribution for a given set of objects. This approach lets us learn and then
sample from the distribution of raw detector responses, conditioned on the
parameters of the charged particle tracks. To evaluate the quality of the
proposed model, we integrate a prototype into the MPD software stack and
demonstrate that it produces high-quality events similar to the detailed
simulator, with a speed-up of at least an order of magnitude. The prototype is
trained on the responses from the inner part of the detector and, once expanded
to the full detector, should be ready for use in physics tasks.Comment: This is a post-peer-review, pre-copyedit version of an article

The biology of Simulium erythrocephalum and S. chelevini (Diptera, Simuliidae): Morpho-logical, ecological and molecular data
The subgenus Boophthora is a typical Palearctic taxon, which includes only 6 species, among them. Simulium erythrocephalum has a transpalearctic distribution. In Europe, Adler notes only the species S. erythrocephalum, and Yankovsky – two species S. (Boophthora) erythrocephalum and S. (Boophthora) chelevini. According to morphological characteristics, these species differ in their life stages. We have studied the development of S. erythrocephalum and S. chelevini from three rivers of Volyn region, Ukraine (Styr, Chornoguzka, Putylivka) from 2017 to 2019. We used the EPPO PM7 / 129 standard. Collected samples, 615-bp fragments of the COI gene were sequenced from five individuals of S. erythrocephalum and five individuals of S. chelevini and compared with four samples of S. erythrocephalum from the GenBank. We obtained the nucleotide sequence of S. chelevini. All of the S. erythrocephalum samples from Ukraine had 692 bases, the S. erythrocephalum samples from Armenia had 673 bases. S. erythrocephalum and S. chelevini did not have any intraspecific variations. These intraspecific variations were not larger than the interspecific variations. It has been proved that the populations of S. erythrocephalum and S. chelevini from medium and small rivers of Volyn do not differ in biological, behavioural and genetic characteristics. Comparison of S. erythrocephalum and S. chelevini life stages showed clear differences in 20 morphological features, which are probably manifestations of phenotypic variability. Comparison of species with data from the GenBank from Spain and Armenia on the mitochondrial cytochrome c oxidase subunit I (COI) gene confirmed the opinion that S. erythrocephalum and S. chelevini are one species. On the phylogenetic tree, the data are not grouped, there is no clear separation of the clades. Bootstrap values are 95–100%, which may indicate a significant similarity of all studied samples and the lack of isolation of individual morphotypes from Volyn, Spain and Armenia. To finally confirm the taxonomic position of these two species, additional research is needed covering more individuals from different parts of Europe and analysis of more genes
