This study justifies the selection of a radiation sensor for explosion and fire hazard monitoring systems. Preference is given to radiation sensors that perceive the energy of heated bodies, in this case a flame, and convert it into an electric signal. Since this energy is dissipated in the communication channel from the flame to the sensor and in the sensor itself, an analytical description of these losses and radiation energy in general is given, which is very important for assessing the sensitivity of the sensor. The following scheme of investigation of flame radiation energy is proposed. The source of radiation is stationary flame of various combustible substances, radiation energy of which is transmitted to the sensor through a fixed hole in a heat-tight screen in an air medium. The sensor is installed at a different distance from the flame, which makes it possible to detect the loss of radiation energy with distance. The sensor sensitive element is a metal bolometer OPB-4K, which receives infrared radiation flux amplified by a reflective mirror. Conversion of thermal radiation into electrical signal is performed by DC Bridge, to the arm of which the bolometer is connected. An amplifier is connected to a device setting threshold of sensor actuation. The threshold device, in turn, controls the thyristor switch, which allows turning on the power supply circuit of the actuator. The sensor operation is performed from individual power supply unit. The presented material is of great importance for the state service bodies in the field of fire safety and design organizations. It draws attention to the problem of improving automatic local means of explosion and fire protection.

In this paper, we propose a sensor for the density and composition of the upper atmosphere (ionosphere), designed for installation on nanosatellites. The relevance and existing problems of direct instrumental studies of the ionosphere at altitudes of 150-500 km are shown. Of the existing types of vacuum meters, the most suitable for autonomous operation at these altitudes are ionization vacuum meters with inverse magnetron primary converters with a cold cathode. However, the existing industrial types of such vacuum meters are unsuitable for operation in the ionosphere due to high concentration of charged particles in the air, resulting in large distortions of the readings. In addition, they have large weight and size characteristics and energy consumption, which exclude the possibility of their installation on nanosatellites. To solve these problems, a mathematical model of the electrophysical processes, occurring in the core of such a converter, was developed which significantly reduced its weight and size characteristics and energy consumption. And to eliminate the influence of charged particles, it is equipped with an electron-ion trap, which additionally made it possible to measure the concentration of electrons and ions in the environment. The design of such a combined converter is described, and calculations of the electric and magnetic fields in the core of the vacuum gauge converter and the electric fields in the interelectrode space of the trap are performed. A method for calculating the current values of such a combined converter has been developed, which makes it possible to estimate the required measurement ranges of the sensor measuring channels. The results obtained allow us to proceed with its experimental design.

In this work, an analysis was made of the relevance of the cultivation of microalgae. Since microalgae have a short growth cycle, and production does not require large costs: they only need water, sunlight and nutrients to grow, they do not occupy fertile lands, there are no seasonal restrictions, it was concluded that microalgae are of interest as an object of mariculture. The paper outlines the main problems that arise when conducting research on microalgae directly in the field (in a reservoir) and substantiates the task of developing an autonomous system for researching algae in conditions close to natural. For the implementation of the tasks, a project of a mobile installation is proposed, the main advantage of which is the possibility of using it in the field when organizing expeditionary work. The use of the installation will make it possible to study microalgae cultures in conditions as close as possible to natural ones. During the development of the project, the main requirements for the installation were formulated, namely: light conditions, gas supply and mineral components of the nutrient medium. In the presented project, a list of systems required for a stand-alone installation was determined, as well as requirements for them. A block diagram of an autonomous system has also been developed, which allows us to consider the principle of operation of the device. Based on the results of this work, it was concluded that an optimal design was proposed that provides control of the main parameters of growth and physiological state, as well as the ability to easily control them. Distinctive features of this system are mobility, design reliability and availability of repair, as well as low cost. Using the installation in expeditionary conditions will allow you to quickly obtain data on the growth of various species and strains of microalgae, without leaving the reservoir, and in the absence of laboratory conditions.
Features of seasonal variability of hydrological and hydrochemical characteristics of subsurface waters of the northwestern Black Sea

Published: July 2021

In our work, based on the archival data of observations carried out in 1955 – 2015, hydrological and hydrochemical characteristics in the 10–30 m layer in the northwestern shelf (NWS) of the Black Sea, including the Danube estuary area are analyzed. Intra-annual changes in dissolved oxygen and water temperature in the NWS and in the Danube estuary area are shown to have a well-pronounced seasonal character. Water temperature in the estuary area of the Danube is characterized by lower values in all seasons than in the NWS. Salinity at the horizons of 10 and 20 m in winter in the estuary area of the Danube is lower than in the NWS due to the freshening of the upper mixed layer by river runoff. In spring, resulting from increased river runoff, an increase in the stability of water stratification occurs, which prevents the spread of heat inland and vertical exchange of oxygen. The strongest freshening in the studied layer is established at the horizon of 10 m. In spring, the southerly winds “trap” river waters in the shallower part of the shelf, and westerly winds give rise to the spread of freshened waters to the east. The summer-autumn period is characterized by low intensity of vertical and horizontal water exchange, which reduces the flow of oxygen to the subsurface layers. Harmonic analysis shows that in the Danube estuary area and in the NWS, the annual signal is dominant for temperature, salinity and oxygen, except for salinity at the 30 m horizon in the estuary area of the Danube. The semiannual harmonic of salinity at 30 m in the estuarine area of the Danube is most likely related to both limited data availability and their noisiness.

Based on the data of the expedition carried out in August 2012, the features of the structure of the salinity and fDOM concentration fields, as well as the correlation between these values ​​in the Dnieper-Bug estuary, are analyzed. It is shown that the salinity field in the Dnieper-Bug estuary is characterized by all structural features typical of coastal sea areas freshened by river runoff, while the fDOM concentration field has anomalous properties due to the presence of an anthropogenic component of this value. The presence of fDOM of anthropogenic origin is most significant in the western part of the Dnieper estuary and is related to the influence of the city and port of Ochakov. The maximum content of fDOM was recorded here, which caused an anomalous horizontal distribution of this substance concentration, increasing from the mouth of the Dnieper to the open Black Sea waters. The contaminated areas of the studied water areas, which are adjacent to settlements and occupy the predominant part of the water surface of the Dnieper-Bug estuary, are characterized by an increased fDOM content and intrusive feature of the vertical structure of this substance concentration field of. It is revealed that in the Dnieper-Bug estuary there is no inverse correlation between the salinity fields and fDOM concentration, which is typical for unpolluted coastal waters, freshened by river runoff. A similar anomaly is an indicator of the pollution of coastal waters with organic matter.

We investigated changes in the content of mineral forms of nitrogen formed as a result of mussel vital activity in non-flow conditions under favorable temperature and aeration, but with food deficiency, as a possible factor influencing mussel flap movement and valvometry results. A laboratory 11-day experiment was carried out with mussels 24–26 mm long. The dry weight of their soft tissues was about 35 mg. The experiment consisted of five exposures lasting 17-67 h. The mussels were kept in 3-liter vessels with 3 individuals in each, feeding only on the natural food available in this volume of water. In parallel, vessels with aerated water without mussels in them were exposed. Ammonium, nitrite, and nitrate concentrations were measured at the beginning (i.e., in fresh seawater from the Sevastopol coastal zone) and at the end of each exposure. It was determined that, compared to the initial level at the end of the exposures, on average, the content of ammonium in vessels with mussels increased by 250%, nitrite – by 25%, and nitrate – did not change. In vessels without mussels, the content of ammonium, on average, decreased by 250 %, changes in the level of nitrite and nitrate corresponded to changes in the concentration of these nitrogen forms in vessels with mussels. The greatest variability was characteristic of the final values of ammonium concentration, in some exposures it could increase by 700 %. However, the maximum value of ammonium content during the experiment reached only 21, 7 μg N/l, which is two orders of magnitude lower than its MPC level for marine fishery objects. It follows from the obtained data that in experiments with mussels kept in non-flow conditions with food deficiency, the probability of the effect of ammonium excreted by them, as well as of products of its further biological oxidation on valvometry results is not high.

This research has been aimed at finding the possibilities for application of the linear regression models, as a part of the machine learning methods, in visual representation of the spatial patterns of Artemia salina distribution in the Southern Sivash. Development of such models allows for estimation of A. salina biomass in water bodies with high accuracy. For investigation of maximum absorption levels in different parts of the light spectrum, spectral signatures at all the monitoring stations have been compared with the satellite data, and the analysis of the absorption spectra for astaxanthin and hemoglobin has been conducted with a spectrophotometer. As a result, Sentinel-2 satellite looks very promising as a key spatial data provider that can be of major help in increasing the frequency of A. salina monitoring in the Southern Sivash. The linear regression models, fitted by the third and the fourth degree polynomials, have shown satisfactory results, suitable for their subsequent use in fisheries. On the other hand, it should be noted that these models are slightly prone to overfitting, which to some extent can distort further forecasts feeding upon the new data. In turn, linear regression models fitted by a polynomial of the first degree show less accurate results, but their advantages include the lack of tendency to overfit. It is also worth noting that small-sized datasets within the scope of this investigation do not appear to be problematic, and simple machine learning algorithms can provide good accuracy results, which are suitable for further application in this field.

Published: July 2021

In this study, methyl α-D-glucopyranoside and its modified derivatives were optimized by employing density functional theory (DFT) with B3LYP/3-21G level theory to explore their structural and thermodynamic properties. Electronic energies, enthalpies, Gibbs free energies, dipole moments, Highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) gaps, the density of states (DOS) and molecular electrostatic potential (MEP) of these modified compounds were found optimal in the subsequent analysis. Molecular docking has been performed against potential inhibitors of the Bacillus subtilis Obg protein (PDB: 1LNZ) to search the binding affinity and mode(s) of six compounds that have significant antibacterial and antifungal activities. It was found that the selected glucopyranoside derivatives have strong interactions mainly with Arg236 and Arg238 residues of the Bacillus subtilis Obg protein, and the molecules were surrounded by other active site residues like Lys156, Pro91, and Glu333. An absorption, distribution, metabolism, excretion, and toxicity (ADMET) calculation reveals that the modified derivatives are less toxic and have improved pharmacokinetic features over the parent drug. This computational investigation showed that these methyl α-D-glucopyranoside derivatives might be used as potential inhibitors against the promising antibacterial and antifungal activities for future studies.

How does historical faith complement Immanuel Kant’s philosophy of religion?
Authors: Kupś Tomasz
Published: July 2021

In modern interpretations of Kant’s philosophy of religion, a shift away from exclusionary moral reductionism occurs. Consequently, at least since the 1970s, historical faith has been appreciated as a necessary and desirable element of Kant’s philosophy of religion. One of the reasons prompting Kant to include historical faith in his system of the philosophy of religion is what commentators on Kant’s philosophy call the ‘moral gap’. For there is a disproportion between the limited competence of man as a natural being and moral goals that seem unattainable. For the believer, the content of historical faith offers a real solution to the disproportion between his limitations as a natural being and the goals set for him by practical reason. For the believer, the ‘moral gap’ is not just a theoretical problem, but an existential challenge whose solution does not lie within his own limited competence. In this article, I consider whether historical faith can also provide a theoretical supplement to the picture of one’s own life. If so, then the content of historical faith may also prove important for the non-believer.

Covid-19 is a new type of coronavirus that has not been previously identified in humans. Covid-19 epidemic spread far more quickly than before all over the world. Therefore, massive preventive measures are needed to reduce the spread of Covid-19. This study aimed to analyze sociodemographic factors that influence prevention behavior of Covid-19 transmission. This was a quantitative study with cross-sectional design. This study located in NTT, West Kalimantan and East Java. The time of study was in June 2020. The sample of 96 subjects were selected by stratified random sampling technique. The dependent variable is the prevention behavior of Covid-19 transmission. Independent variables are sociodemographic include age, sex, education, and employment status. The data were collected by using an online questionnaire. The data were analyzed by using multivariate analysis. The prevention behavior of Covid-19 transmission were influenced by age (b = 0.31, 95% CI = 0.02 to 0.59, p = 0.036), education (b = 2.16, 95% CI = 0.15 to 4.17, p = 0.036), and employment status (b = 2.24, 95% CI = 0.59 to 3.90, p = 0.008). Gender (b = -0.45, CI 95% = -3.64 to 2.74, p = 0.781) had no effect on the prevention behavior of Covid-19 transmission. From the results of this study, it was found that research subjects with a more mature age, high level of education, and higher employment status could take Covid-19 prevention measures well. However, in this study, the results also showed that the gender of men and women did not influence Covid-19 prevention behavior. It is interesting to study the effect of each independent variable (age, education, occupation and sex) on the dependent variable (Covid-19 transmission prevention behavior).

Published: July 2021

The aim of the study is to study the influence of the personal characteristics of a nurse on professional suitability for work in a pediatric hospital. The results of the study allow us to assert that the professional suitability of a nurse is influenced by a number of characterological abilities, including such as moral normativity, neuropsychic stability, adaptive abilities, and communication skills. Conclusion. When hiring, a psychodiagnostic examination should be carried out to study the characterological characteristics of future employees, which will reduce the turnover of personnel in pediatric departments. Taking into account the psychological characteristics that affect the professional suitability to work in the pediatric department, it is possible not only to select the most psychologically ready staff, but also to prevent the development of professional deformations and burnout syndrome in employees.

Published: July 2021

The World Health Organization (WHO) as a pandemic recognized the outbreak of the novel coronavirus COVID-19, which was first reported on December 8, 2019 in Hubei Province in China, on March 11, 2020. This disease was recognized as an infection with a new beta-coronavirus. Today, the current problem is COVID-19 and its effect on blood vessels and blood. Although COVID-19 primarily affects the lungs, causing interstitial pneumonitis and severe acute respiratory distress syndrome (ARDS), it also affects other organ systems. COVID-19 is manifested by hypercoagulation, pulmonary intravascular coagulation, microangiopathy, and venous thromboembolism (VTE) or arterial thrombosis. Clinically, the vascular dysfunction associated with COVID-19 manifests itself outside the lungs in various ways, including deep vein thrombosis, pulmonary embolism, large artery thrombosis, and multiple organ venous and arterial thrombosis, and these manifestations are attributed to factors such as hypoxemia, viral sepsis, immobility, and sometimes vasculitis. In some cases, DIC syndrome (which is a simulator of vasculitis) can occur with the lightning-fast lung disease COVID-19, and is also characterized by diffuse thrombosis and bleeding. If you exclude DIC and large vessel thrombosis, it is clear that patients with severe COVID-19 pneumonia may also have severe changes such as skin vasculitis, suspected cerebral vasculitis, and multiple organ failure, resulting in suspected viral endothelitis, direct viral infection, or vasculitis. Understanding the vascular effects of COVID-19 is essential for comprehensive medical care.
Label-Free White Blood Cell Classification Using Refractive Index Tomography and Deep Learning

Published: July 2021

Objective and Impact Statement
. We propose a rapid and accurate blood cell identification method exploiting deep learning and label-free refractive index (RI) tomography. Our computational approach that fully utilizes tomographic information of bone marrow (BM) white blood cell (WBC) enables us to not only classify the blood cells with deep learning but also quantitatively study their morphological and biochemical properties for hematology research.
Introduction
. Conventional methods for examining blood cells, such as blood smear analysis by medical professionals and fluorescence-activated cell sorting, require significant time, costs, and domain knowledge that could affect test results. While label-free imaging techniques that use a specimen’s intrinsic contrast (e.g., multiphoton and Raman microscopy) have been used to characterize blood cells, their imaging procedures and instrumentations are relatively time-consuming and complex.
Methods
. The RI tomograms of the BM WBCs are acquired via Mach-Zehnder interferometer-based tomographic microscope and classified by a 3D convolutional neural network. We test our deep learning classifier for the four types of bone marrow WBC collected from healthy donors (

n

): monocyte, myelocyte, B lymphocyte, and T lymphocyte. The quantitative parameters of WBC are directly obtained from the tomograms.
Results
. Our results show >99% accuracy for the binary classification of myeloids and lymphoids and >96% accuracy for the four-type classification of B and T lymphocytes, monocyte, and myelocytes. The feature learning capability of our approach is visualized via an unsupervised dimension reduction technique.
Conclusion
. We envision that the proposed cell classification framework can be easily integrated into existing blood cell investigation workflows, providing cost-effective and rapid diagnosis for hematologic malignancy.
CONSIDERAÇÕES SOBRE TRABALHO E INTERAÇÃO NO PENSAMENTO DE HABERMAS
Authors: Costa Edilson da
Published: July 2021

Este artigo apresenta uma reflexão sobre a dimensão filosófica dos conceitos de trabalho e interação em Habermas. Mostra o caráter ambíguo do trabalho enquanto realização e afirmação da especificidade humana e alienação dos sujeitos que trabalham. Traz ainda uma visão positiva do trabalho, pois propõe uma via alternativa para reorganizar os contextos comunicativos de interação de acordo com outros padrões que não os orientados para o agir estratégico.
CONCEPÇÕES DE LEI NATURAL E DE LEI SECULAR CONTIDAS NA REFLEXÃO FILOSÓFICO-TEOLÓGICA DE ORÍGENES
Authors: Nascimento Sidnei Francisco do
Published: July 2021

O método de interpretação alegórica de Orígenes se apropriará de uma passagem do Evangelho segundo São Mateus (22,21) que trata a respeito da célebre passagem de “dar a César o que é de César e a Deus o que é de Deus” e de um trecho da Epistola aos Romanos (13,1-14) que discorre a respeito da submissão da alma à autoridade civil. Tal exegese apresentará a complementaridade, embora com significados diferentes, entre as concepções de lei natural e de lei secular. A correspondência entre uma lei e outra, transitará entre o mundo sensível e o inteligível ou, dito de outra forma, entre o mundo terreno e o mundo espiritual, que terá o livre-arbítrio como um elemento indispensável, porque se traduzirá num dever de consciência, que incidirá na noção tricotômica de alma paulina movimentando-se entre os desejos da carne e os desejos do espírito.
CONCEITO DE “ESCRAVIDÃO NATURAL” NA FILOSOFIA MEDIEVAL
Authors: Luís Gutiérrez Jorge
Published: July 2021

O presente artigo trata sobre o conceito de escravidão natural no pensamento medieval. Este conceito que foi desenvolvido principalmente por Aristóteles no capítulo I da Política foi retomado por pensadores tais como Santo Agostinho, Tomás de Aquino, Tolomeo de Luca e John Major. A maioria rejeitou este pensamento e quando o aceitaram entendiam por “natural” algo diferente de Aristóteles. O que estes pensadores escreveram sobre este conceito e como o receberam da antiguidade grega é o tema do presente trabalho. Terminaremos fazendo referência, embora brevemente, sobre como o conceito de “escravidão natural” foi amplamente usado nas tentativas de justificar teoricamente a conquista de América no século XVI. Especial referência merecem a este respeito os dominicanos John Major e Juan Ginés de Sepúlveda.

Efectos de un programa de investigación acción participativa sobre el liderazgo situacional y los estilos de aprendizaje en universitarios de Lima metropolitana
Authors: Franco Mendoza Josué Michael , López Munguía Olimpia
Published: July 2021

El principal objetivo del presente estudio fue el de determinar el efecto de un programa de investigación acción participativa (IAP), siguiendo el modelo de Paredes (1998), sobre el liderazgo situacional y los estilos de aprendizaje en estudiantes universitarios de las facultades de psicología y educación en una universidad pública de Lima metropolitana. Para dicho propósito participaron 32 estudiantes de ambas facultades, entre hombres y mujeres, divididos aleatoriamente en 2 grupos de 16 personas: uno al cual le sería aplicado un programa de competencias emocionales y otro del cual se obtendrían únicamente medidas pre y post test, en marco de un diseño experimental. Entre los instrumentos empleados se incluyeron los de la Escala de Liderazgo Situacional (Aburto, 2014) y el de Estilos de Aprendizaje (CHAEA) de Horney y Alonso. Los resultados del estudio ponen en evidencia efectos signiticativos del programa, a partir del contraste de diferencias en las puntuaciones sobre ambas variables, sobretodo en los estilos de liderazgo dirigir y participativo, detectándose además correlaciones significativas luego de la aplicación del programa entre los estilos de aprendizaje activo y pragmático. Se concluye que el programa evidencia adecuados resultados; sin embargo, se recomienda extrapolarlo a otros grupos, dadas las características del público objetivo de actividades donde fue desarrollado.
