Authors: Legkih A , Skomorokhov A , Sadovnichy R
Published: January 2022

Currantly, to ensure the protection of structural steels from corrosion and erosion influence of the lead coolant, a passivation technique of steel serfaces are chosen. To implement the passivation technique in the process of reactor loop operation it is required the continuous monitoring of the oxidation potential of the lead coolant and its correction, in the case of going beyond the established boundaries. To control the oxidation potential in the lead coolant the oxygen activity sensors are used. In this case, the measured parameter is the thermodynamic activity of oxygen. As a parameter, which characterize the level of oxidative potential of the coolant, the concentration of oxygen dissolved in the lead coolant is used. The relationship between the concentration and the oxygen thermodynamic activity is carried out by the solubility of oxygen in liquid lead. The paper is dedicated to the calculated estimation of oxygen solubility uncertainty in the liquid lead on the basis of available experimental data and its contribution to the uncertainty of oxygen concentration dissolved in the lead coolant.

Published: January 2022

The study investigated the effect of heterogeneous shielding on the preparation of macroconstants for various mixtures. By comparing the effective multiplication factor calculated using multigroup macroconstants of the mixtures obtained for the “infinite” and final geometries, it was determined how significantly the cross sections are shielded and how much this affects the criticality of the entire system. The study is part of the research work on the analysis of the criticality of a fast physical stand (BFS) and is intended to work out the methodology for carrying out multigroup and continuous-energy calculations. The work is carried out on the model of the benchmark BFS2-62-3A, which was carried out on the critical stand BFS-2 (IPPE, Obninsk) in 2000 to simulate the core of the BN-600 reactor with a hybrid U-Pu fuel load and a stainless reflector become. BFS is a set of tubes filled with pellets with different mixtures (uranium, sodium, steel, etc.). The research tool is the software package SCALE-6.2.1. It consists of various control modules united by a common user interface. The calculations of Keff and reaction rates were carried out by the CASAS6 criticality sequence of the SCALE software package using the KENO-VI Monte-Carlo code. During the work, the library ENDF/B-VII.1 was used with continuous and multi-group views of cross sections (252 and 56 groups). The preparation of the macroconstant libraries was done by the XSProc sequence of the SCALE soft-ware package using two different methods: BONAMI and CENTRM. In addition to the experimentally obtained values, the values obtained using the MMKKENO, TRIGEX and Serpent software complexes were used for comparison.

Published: January 2022

The purpose of this work is to estimate the uncertainties of the neutron multiplication factor and the isotopic composition of the high temperature gas cooled reactor (HTGR) fuel composition arising from the manufacturing uncertainties of the fuel parameters: the uncertainty of the geometric dimensions and number densities of materials. For the evaluation of mentioned characteristics a model of MHTRG-350 fuel block is used. The code SUSA 4.0 (Software for Uncertainty and Sensitivity Analyses) is used to estimate uncertainties and sensitivity coefficients. The analysis is based on multiple calculations using the WIMSD-5 code with selected sets of randomly distributed input parameters. The distributions of the calculated functionals are characterized by mathematical expectations and standard deviations. The results of uncertainty analysis are used as a base for sensitivity coefficients estimation.

Published: January 2022

The concept of the development of two-component nuclear energy based on fast and thermal reactors, adopted in Russia, suggests that in case of intensive development of nuclear reactors, fast reactors will provide fuel for thermal neutron reactors, while plutonium from VVER SNF will be used to produce mixed uranium-plutonium (MOX) fuel fast sodium reactors. Currently, in the global nuclear energy sector, some PWR units are licensed to use a combination of conventional and MOX fuel in them or are in the process of licensing. But plutonium obtained during the reprocessing of spent fuel from the MOX fuel cannot be reused in thermal reactors due to an exceedingly high content of heavy (even) isotopes that do not fission in the thermal-neutron spectrum. As a result, plutonium is accumulated, which is a definite problem for European energy. This problem can be partially solved with the help of fast reactors. Currently, fast energy sodium reactors operate only in Russia - BN-600 and BN-800. BN-800 can operate on MOX fuel, industrial remote technologies to fabricate such fuel is now being developed at a plant belonging to the Mining and Chemical Complex. Having a fast reactor and remote MOX fuel technologies, it becomes possible to organize the export of services - ″improve″ of foreign-grade plutonium unsuitable for reuse in thermal reactors. The joint use of Russian fast reactor technologies and French MOX fuel technologies in thermal reactors for Russia opens up the world export market for plutonium enrichment services, and for the whole world - a new stage in the development of global two-component nuclear energy.
COMPUTATIONAL SIMULATION OF POST-DECOMMISSIONING AFTERBURNING OF FAS FROM UNITS 1 AND 2 OF LENINGRAD NPP

Published: January 2022

The RBMK-1000 reactor operates in a continuous refueling mode. The reactor core comprises FAs across the burn-up spectrum, from fresh fuel assemblies to the most burnt-up ones. Following the reactor shutdown for decommissioning, the majority of irradiated fuel assemblies (IFA) have the potential for further use (the so-called afterburning) at operating NPP units. Most of the irradiated fuel assemblies have a burn-up fraction, which is far from the specified threshold value. The neutron multiplication factor in the cell exceeds the core average value and, therefore, the IFA loading makes it possible to increase the reactivity margin to the desired value. Reuse of spent fuel assemblies in reactors at other power units offers a number of advantages. In economic terms, afterburning is able to reduce the use of fresh fuel assemblies (FFA). In terms of radioactive waste handling, afterburning is able to reduce the number of irradiated fuel assemblies, which require long-time storage in a spent nuclear fuel repository thus reducing the IFA and radioactive waste disposal loads. JSC NIKIET has proposed the use of irradiated fuel assemblies from units 1 and 2 of Leningrad NPP shut down after decommissioning in reactors at units 3 and 4 of the same NPP.
ON MODELLING OF THE INITIAL SOURCE OF PROMPT NEUTRONS FOR SOLV-ING NONSTATIONARY PROBLEMS BY THE MONTE CARLO METHOD
Authors: Ioannisian M , Davidenko V , Dyachkov I
Published: January 2022

The work is devoted to the problem of initial neutron source distribution for modeling kinetic transient processes by the direct analogue Monte Carlo method. An algorithm is proposed for modeling such a source. The source algorithm implemented in the KIR2 program and designed to solve the problem of taking the system out of the critical state by introducing a perturbation (reactivity). Only prompt neutrons are considered. For the neutron source distribution, a phase coordinates of the neutron are used. The phase coordinates are determined in the preliminary calculation of the critical state. The results of testing the algorithm on non-stationary test problems (an infinite environment and RP1GS) are presented. In each task, the geometric area is filled with material presented in the form of single-group macroparameters. The results of calculating the integral neutron flux density were compared with the solution of the point kinetics equations. Good agreement was obtained - the deviation during all the calculated processes does not exceed 0.4 % in the integrated flux density, but it increases at the end of the processes with the introduction of negative reactivity up to 2.5 % with a small number of neutrons in the system.
COMPUTATIONAL ANALYSIS OF THERMAL HYDRAULIC STABILITY REVERSE STEAM GENERATOR NUCLEAR RESEARCH FACILITY MBIR

Published: January 2022

The stability of the circulation in the steam-water circuit, that is, the preservation of the thermohydraulic parameters within acceptable limits for perturbations characteristic of the operation, largely determines the reliability of the steam generator itself. Under certain conditions, pulsating pressure, flow and temperature pulsations may appear in boiling apparatus. For the first time, ripples were encountered during the creation of once-through boilers, and the harmful effect of flow instability on the apparatus design led to the need for a detailed study of the problem. In this work, a computational analysis of the thermal-hydraulic stability of the reverse steam generator (OPG) of the MBIR nuclear research facility (NRF) is carried out. The need for such a study is due to the fact that the OPG consists of three parallel connected steam generating modules. With such a design, water flow rate pulsations may appear, including with overturning flow rates in separate steam-generating channels. To avoid this, it is necessary to conduct throttling at the inlet to each OPG module, therefore, in this study, the hydraulic resistance of the chokes is determined. The research methodology is based on the use of a numerical thermohydraulic model of a reverse steam generator, made by means of a certified thermohydraulic design code HYDRA-IBRAE/LM/V1. The OPG RNU MBIR at the economizer and superheating sections has twisted heat exchange intensifiers that direct water and steam both in the longitudinal and transverse directions relative to the bundle of heat exchange tubes. This circumstance required a special approach in calculating the hydraulic resistance and heat transfer coefficients along the path of the OPG modules. After the creation of the computational model, it had to be verified, and since the design of the OPG of the NRF MBIR is similar to the design of the OPG of the BOR-60 reactor, the experimental data obtained on the OPG BOR-60 were used for verification. The calculations of the normal operation modes of the OPG NRF MBIR after the throttling of the modules confirmed the absence of fluctuations in the flow rate in these modes.

Published: January 2022

The work is devoted to the analysis of uranium radiation heating results under the action of neutron radiation. The revealed results discrepancies in the radiation heating modeling of the uranium 235 and 238 using FENDL 3.1d and ENDF nuclear data libraries motivate the study. At the same time, all initial data in the computational model, namely, the neutrons energy spectrum, mass of fissile material, geometry and surrounding structures composition were identical. In the course of the work, the results of energy release calculations in uranium cells were compared using various libraries. Analytical evaluation of the radiation heating results in test cells is given. The obtained data indicate erroneous values of neutron kerma factors in FENDL 3.1d nuclear data library. Fusion Evaluated Nuclear Data Library was created by the working group of the Nuclear Data Section of the IAEA in the mid-1990s. FENDL is focused on application in the design of fusion plants as well as plants for materials testing such as IFMIF. The expanded application required the addition of some materials to the library, the expansion of the energy range to higher energies and the addition of data for reactions caused by charged particles. Version 3.1d was released in January 2018 and is widely used in nuclear analysis of structural materials for the experimental fusion reactor ITER and the demonstration fusion reactor DEMO. The results of this work have been submitted to the ITER International Organization contact group for presentation to the developers of the FENDL library.

Authors: Blokhina A , Lyakishev S , Korotkova O
Published: January 2022

The article investigates the influence of coolant flow profile nonlinearity through straight-pipe steam generators tube assembly for fast neutron reactor with sodium coolant on heat exchanger power. When designing steam generators, a very important task is to correctly calculate the output parameters of the steam generator, especially the power. For the plants without reference solutions it is necessary to perform a deep analysis of the factors affecting on calculated parameters and to incorporate these parameters in the codes. An example of a new plant that do not have analogues is a shell-type steam generator for perspective fast neutron plants with liquid metal sodium coolant. The application of new solutions in steam generators design requires experimental and calculational justification of thermal hydraulic with the use of modern calculation codes. Power calculation of steam generator is carried out by thermohydraulic code “KORSAR/GP”, “PGN-2K”. One of the assumptions in coolant path parameters calculation model (tube space) is a uniform velocity profile by cross-section of tube assembly. It’s also accepted, that each heat exchange tube has the same expense of feed water. On the other hand calculational CFD and experimental studies at aerodynamic model of steam generator showed the presence of significant unevenness of coolant expense by tube space cross-section which is not taken into account in thermohydraulic calculations. The article contains the methodic of accounting for the known uneven coolant flow profile by tube space cross-section in liquid metal steam generator calculation. Based on the results obtained, measures to improve power output and reliability are proposed.

Authors: Ashraf O , Tikhomirov G
Published: January 2022

The current work introduces a reliable safety system based on control rods in addition to the online feed system reactivity control in the Single-fluid Double-zone Thorium-based Molten Salt Reactor (SD-TMSR). The reactivity of the SD-TMSR core is controlled through two systems of control assemblies: (1) the Control Safety Devices (CSD) and (2) the Diverse Safety Devices (DSD). In the present work, the control rods are natural B4C and B4C-90 (with 90% weight content of the main absorbing 10B isotope). Since the numbers and distribution of control assemblies in SD-TMSR have not been studied previously, we proposed a unique distribution as a starting point for this analysis. The distribution of these 25 fuel assemblies with control rods in the SD-TMSR core and their numbering scheme were presented in this paper. Additionally, excess reactivity, control rod worth, and shutdown margin were calculated using Monte Carlo code Serpent2. Analysis results showed that the proposed placement of the control rods will make it possible to compensate for excess reactivity during fuel burnout and emergency shutdown of the reactor.

The development of an energy system, including nuclear, is a long and multi-stage process. The complexity of the process is determined by the deep degree of workforce decomposition at nuclear power facilities, high capital and science intensity of the industry. When assessing the prospects, it is necessary to take into account many significant external factors and uncertainty of the future macroeconomics development trends. In the process of analysis and decision-making on the development of the country's energy system, there are many participants of technological concepts are involved, often with divergent interests. The main task of justifying decisions on the development of the energy industry and, in particular, nuclear power are coordination of interests of all subjects of relations and methodology the formation of mechanisms to ensure the development process. In such an assessment, the ultimate goal is sustainable development. To determine the technological development of the energy system with nuclear and non-nuclear power technologies for the next 5-10 years, it is necessary to assess the long-term prospects of such scenarios. This task requires a multi-criteria approach to analyze the competitiveness of technology using a list of criteria of competitive advantages, combining economic indicators and indicators that characterize safety, environmental impact, risks of implementation, development prospects. This paper discusses the results of multi-criteria system analysis using international assessment tools. The transfer of Russian nuclear power to the two-component nuclear energy system with VVER and BN reactors and the expansion of the international fuel business by providing a full range of NFC services was evaluated using a set of key criteria.
DEVELOPMENT OF A COMPACT PULSED NEUTRON SYSTEM FOR MEASURING THE MASS OF FISSILE NUCLIDES IN SOLID RADIOACTIVE WASTE
Authors: Bezhunov G , Rykov N , Ryazanov B
Published: January 2022

A system for measuring the mass of fissile nuclides (FN) in solid radioactive waste (SRW) in containers up to 200 liters has been developed, manufactured and tested. The measuring system includes a pulsed neutron generator (PNG) with a neutron output of 2·108 neutrons/s, a neutron moderating unit with counters of supra-cadmium neutrons and a chamber for containers up to 200 liters, a time pulse analyzer, a personal computer with a software for accumulation and processing of time spectra of pulses from neutron registration. Experimental and computational studies have been carried out for models of containers with solid radioactive waste of 120 and 211 liters with matrices of quartz sand, graphite and paper of various densities with FN content in an amount from 0.01 to 100 g using reference or well-characterized samples with different enrichment in U-235 (from 5 to 90 %) and PuO2 reference sample, with different chemical composition (dioxide, uranyl nitrate solution, oxide-nitrous oxide), different geometrical sizes, placed homogeneously or heterogeneously over the volume of the container. The parameters of the measuring system were determined, including the response values in units of counts per second per gram of FN in the container and per the PNG neutron. The measurement time at an PNG frequency of 20 Hz with a neutron yield of ~107 neutrons/pulse is from 100 to 300 s. The lower limit for U-235 mass measuring for typical TPO matrices is 0.01 g per container. The influence of various factors on the measurement results was estimated: the moisture content of the matrix, the chemical composition and density of the matrices, the mass fraction of U-238 in uranium, the heterogeneity of the FN arrangement in the container, the presence of internal neutron sources. Measurements of the mass of fissile nuclides in containers using the developed system are possible for the case of the presence of internal neutron sources in the container with an intensity of up to 5·107 neutrons/s per container.

Published: January 2022

Density, phase composition, microstructure and thermal conductivity of the U-10 wt. % Zr alloy manufactured by induction melting with subsequent casting into quartz molds and turning to size have been investigated at JSC “SSC RF - IPPE”. For comparison, the density and thermal conductivity of the U-10 wt. % Zr alloy produced by melting followed by extrusion and turning to size were investigated. To determine the density, a hydrostatic weighing method was used. The average density values of the cast and extruded alloy were respectively 98.8 and 97.5 % of the theoretical density, which was calculated according to the rule of mixtures. The results of studying the microstructure using a scanning electron microscope are presented. It is shown that the cast alloy U-10 % Zr is a metal matrix in which zirconium-enriched particles of arbitrary shape are distributed. In a metal matrix, the bulk of the volume is occupied by the α-U, and there are also precipitates of the δ-phase in the form of thin plates. A lower value of the microhardness of the alloy is noted in comparison with the data published in the known literature. The results of measuring the thermal conductivity at temperatures from 100 to 750 °C for the U-10 wt. % Zr alloy obtained by casting and extrusion are presented. The stationary axial heat flux method (or method of plate) was used to measure the thermal conductivity. Alloy samples made in different ways have almost the same thermal conductivity at 200 °C. With an increase in temperature, the discrepancy in thermal conductivity between the samples of the cast and extruded alloy gradually increases, and the thermal conductivity of the extruded alloy turns out to be lower, which is especially noticeable in the temperature range of 600-750 °C. The data obtained are compared with the results of published works. The measured values of the thermal conductivity of the cast alloy U-10 wt. % Zr up to a temperature of 750 °C do not disagree with the literature data. It was found that at a higher temperature, the alloy softens, which, in turn, leads to deformation of the test specimen and an increase in the measurement error when using the axial heat flux method.
POSSIBILITY OF APPLICATION OF ZrO2-MgO-CaO CRUCIBLES FOR PRODUCING ALLOY U-10 % Zr

Published: January 2022

It is known that the thermal shock resistance of ceramic crucibles is insufficient for melting uranium alloys in them. Typically, crucibles withstand one or more heats and then break down. The possibility of using nanostructured ceramic crucibles based on ZrO2-MgO-CaO to obtain a U-10 % Zr alloy in an induction electric furnace has been substantiated at IPPE. Crucibles were made in JSC “ONPP “Tekhnologiya” named after A.G. Romashin” from a mixture of zirconium dioxide powders, partially stabilized with nanocrystalline CaO and MgO in a ratio of 30 and 70 wt. %, using two-stage sintering. Such crucibles have a sufficiently high resistance to thermal shock in contact with melts of metals and alloys and withstand 1-3 melts without destruction. Crucibles with various densities (from 5.206 to 5.29 g/cm3) and porosity (from 5 to 9 %) were tested under conditions of heating the melt at a rate of 12 to 19 °C/min to a maximum temperature of 1455 to 1560 °C. The tested crucible ZrO2-MgO-CaO was inserted into a graphite crucible to prevent leakage of the melt in the electric furnace in case of destruction of the ceramic crucible. There was no complete destruction of the crucibles; some crucibles with small cracks could be reused. The best result (three melts) was obtained when using such a crucible with a porosity of about 5 % for melting a charge containing uranium and zirconium. In order to determine the degree of interaction of a uranium-zirconium melt with a crucible based on ZrO2-MgO-CaO, the microstructure and microhardness of the crucible surface in contact with the melt were studied at an elevated temperature of 1600 °C. The surface of all tested crucibles is not wetted by liquid uranium-zirconium melt, and there is no chemical interaction. Nanostructured ceramic crucibles based on ZrO2-MgO-CaO are suitable for melting uranium-containing materials in an electric induction furnace.

The aim of this study was to clarify how male rotating night shift workers cope with male climacteric symptoms and whether coping strategies are different depending on age. A self-administered questionnaire survey regarding coping strategies in male rotating night shift workers over the age of 20 years was performed. Male climacteric symptoms were evaluated by using the Aging Male’s Symptoms scale [AMS]. Of 1,891 questionnaires that were sent, 1,561 were collected. For all of the 16 symptoms, the most frequent strategy was to try to ignore and tolerate the symptoms and the second-most frequent strategy was to take time to relax. The proportions of men who ignored and tolerated psychological symptoms and sleep problems were high in all age groups. The proportions of men who ignored and tolerated the symptom of decline in the feeling of general well-being were high in men in their 20s and low in men in their 60s. The proportion of men who consulted a doctor for the symptom of joint and muscular pain was high in men in their 50s. The most frequent strategy for coping with male climacteric symptoms was to ignore and tolerate the symptoms and the second-most frequent strategy was to take time to relax. There was a difference in coping behavior depending on age in rotating night shift workers.
La madre-alcahueta en el primer Lope: una nota sobre «La ingratitud vengada»
Authors: Piqueras Flores Manuel , Santos de la Morena Blanca
Published: January 2022

Este trabajo analiza el personaje de Corcina en La ingratitud vengada como uno de los escasos ejemplos de madre-alcahueta en la producción dramática de Lope de Vega. Por un lado, a partir de datos globales, se pone de manifiesto que la presencia de madres en escena es mayor en la primera época de Lope, y esta disminuye a lo largo del tiempo. Por otro, se expone que el personaje materno de La ingratitud vengada —una madre-alcahueta— es muy diferente del perfil habitual: una mujer noble, madre de un varón que es a menudo el protagonista. Se vincula la aparición de este personaje, construido a partir de la tradición celestinesca, a la ausencia de figuras paternas, al género de la comedia picaresca y a la probable inspiración biográfica del argumento, que emparenta La ingratitud vengada con El sufrimiento premiado y La Dorotea.

Prácticas de libertad en la gubernamentalidad neoliberal
Authors: Vignale Silvana Paola , Alvarez Luciana
Published: January 2022

Realizamos una reflexión sobre los procesos actuales de subjetivación en el marco de lo que, a partir de los desarrollos de Foucault de finales de los años ‘70 se denomina “gubernamentalidad neoliberal”. Trabajamos genealógicamente desde la constitución del individuo moderno como titular de derechos, donde su relación con el uso público de la razón opera como aquello que garantiza su seguridad al mismo tiempo que certifica su obediencia, y posteriormente con su devenir de sujeto empresarial. Este trabajo nos permite interpelar las relaciones actuales entre sujeto, poder y verdad, a partir de precisar la idea de prácticas de libertad-enunciada por Foucault a comienzos de los años ‘80- como prácticas de resistencia situadas más allá de las libertades modernas. Considerando lo que podría ser un nuevo declive de estas relaciones, nuestra pregunta se dirige a una actualización de la actitud crítica: ¿cómo es posible la inscripción de prácticas de libertad en las tensiones actuales entre libertad y obediencia?

Authors: Johansen Anna-Christina
Published: January 2022

Despite the high practical interest in the commercialization of aspects of personality rights, an independent personality property right has not yet been generally recognized. This paper therefore answers fundamental questions on whether and how the aspects of personality rights can be commercialized. In doing so, it is clarified which characteristics a personality aspect must have in order to be exclusive and transferable. Furthermore, the limits are shown in which the holder of the right and third-parties can commercialize aspects of personality rights. As a result, it becomes clear that the holder of the right can only achieve maximum protection when a personality property right is recognized.
Soziale Wohnraumversorgung innovativ
Authors: Lenz Martin
Published: January 2022

The demand for municipalisation is literally upending the federalist model of German housing policy that has existed until now. This paradigm shift requires a new form of interdisciplinarity involving urban sociology, local policy research and housing promotion. A municipal–state–federal programme termed ‘Housing’ can—analogously to the methodology of the urban development programme ‘Socially Integrative City’—contribute to solving the social question of housing in Germany. The author of this book works as a mayor in Karlsruhe in the field of social housing provision, both practically and politically, as well as in academia as a lecturer at TU Wien, the university of technology in Vienna.
Die Europäische Verwaltungsakzessorietät des Umweltstrafrechts
Authors: Lienert Katharina
Published: January 2022

Transboundary environmental pollution established the need for European regulation at an early stage. When enforcing this legislation, European environmental administrative law – largely harmonised – interacts with criminal law that was until recently exempt from EU competencies. This study examines the interaction of German environmental criminal law with environmental administrative law of the EU and its member states, focussing on legislative technique as well as the tension between national sovereignty and the need for uniform sanctions throughout Europe, and paying particular attention to changes brought by the Environmental Criminal Law Directive.
Die gesellschaftsrechtliche Implementierung von Matrixstrukturen im Konzern am Beispiel der AG, SE und GmbH
Authors: Hannemann Nico
Published: January 2022

More and more companies and groups worldwide are switching to the matrix structure as an organisa-tional model for reasons of efficiency. In practice, the implementation of the matrix structure under com-pany law is particularly difficult. The thesis confronts these difficulties by showing how (European) stock corporations and German limited liability companies can be legally included in a matrix-organised group and how matrix management and matrix managers can be equipped with the necessary instruction and information rights. Furthermore, the complex legal duties of the involved parties in a matrix structure are explained. In addition, recommendations and templates are provided.
Die lateinischen Texte des Schülers Nietzsche
Authors: Wollek Christian
Published: January 2022

Nietzsche’s latin texts, which he wrote between 1858 and 1864 as a pupil of the Schulpforta boarding school, are still underestimated as a subject of research.

These early latin-written texts in prose and verse already show Nietzsches position between art and science, which characterizes especially his later work. For this reason these texts offer not only a deep insight in Nietzsche´s early thoughts, but give also a deep insight in the philosopher’s later work.
Brushite: Synthesis, Properties, and Biomedical Applications
Authors: Issa Khalil , Alanazi Abdulaziz , A. Aldhafeeri Khalid , Alamer Ola , Alshaaer Mazen
Published: January 2022

In this chapter, besides its biomedical applications, the synthesis and properties of brushite were investigated. Brushite consists of two types of crystals, platy and needle-like, and their formation depends on the pH of the medium during precipitation. Platy crystals are formed in a slightly acidic medium, pH = 5, and needle-like crystals at a higher pH = 6.5–7. In this study, the monoclinic brushite crystals were synthesized using dissolution-precipitation reactions. It is found that the brushite crystal growth occurs mainly along the (020) crystallographic plane. The thermogravimetric analysis confirms the presence of the two structural water molecules, which decompose at a temperature range between 80 and 220°C. Brushite was used in the preparation of tetracalcium phosphate mineral, which is the powder component for calcium phosphate cement (CPC). CPC was subsequently prepared from TTCP and phosphate-based hardening solution. In vitro evaluation of the resultant CPC using Hanks’ Balanced Salt Solution results in the growth of nanofibrous crystals of Calcium-deficient hydroxyapatite (CDHA) layers on the surfaces of the CPC. The cultured CPC exhibits new connective tissues and throughout the CaP matrix.
Glucosinolates and Its Role in Mitigating Abiotic and Biotic Stress in Brassicaceae
Authors: Chowdhury Parul
Published: January 2022

Abiotic stresses such as increase in daily mean temperature, changed patterns of precipitation, increase in episodes of drought and floods in future are faced by the plants and pose threats to crop production and food security. Induction of secondary metabolites by several abiotic stress conditions can be helpful in the crop protection against biotic stress and can be a major link between biotic and biotic stress. Plants also face threats by injury caused by herbivores and insects that chew on plants. Plant develops, coordinates and combines defence mechanism to cope with the challenges caused by the injuries. The plant family Brassicaceae (or Cruciferae) includes some of the world’s most economically important crops; especially members of the genera Brassica L. Brassicaceae vegetables are a good source of secondary metabolite that is Glucosinolates. Which are responsible for characteristic flavour and odour, when degraded. Glucosinolates and their degradation products play important roles in stress tolerance, plants respond to abiotic and abiotic stress by systematically accumulating higher levels primary and secondary metabolites for increasing their resistance. Glucosinolates play important role and have a relation with biotic and abiotic stress in Brassica plant family, as they can act as a signalling molecules and affect the physiology of plant.
A Heuristic for Thomist Philosophical Anthropology: Integrating Commonsense, Experiential, Experimental, and Metaphysical Psychologies
Authors: De Haan Daniel D. ,   Philosophy Documentation Center
Published: January 2022

In this study, I outline a heuristic for Thomist philosophical anthropology. In the first part, I introduce the major heuristics employed by Aquinas to establish the objects, operations, powers, and nature of his anthropology. I then identity major lacunae in his anthropology. In the second part, I show how an integrated approach to commonsense, experiential, experimental, and metaphysical psychologies can fill these lacunae and contribute to the enquiries of a contemporary Thomist philosophical anthropology.

Published: January 2022

O presente artigo tem como objetivo analisar a influência de variáveis socioeconômicas na distribuição de casos e óbitos relacionados a Covid-19 no Brasil. Para isso, foram utilizadas variáveis socioeconômicas referentes aos Índices de Desenvolvimento Humano dos Municípios (IDHM) e suas variações IDHM Renda, IDHM Longevidade e IDHM Educação, bem como os dados epidemiológicos sobre a distribuição de casos e óbitos relacionados a Covid-19 no Brasil na data de 02/06/2020. Com base em testes de estatística inferencial (correlação e regressão) referentes a uma amostra de 200 municípios, os resultados indicaram influência relativa, principalmente do IDHM Renda na distribuição de casos e óbitos relacionados à Covid-19 por 100.000 habitantes. Na porção territorial Norte-Nordeste do Brasil, as áreas com a presença predominante de municípios com baixo IDHM Renda apresentaram também maiores valores de casos e óbitos por 100.000 habitantes, ao passo que na porção territorial Centro-Sul, as áreas com IDHM Renda mais elevado, apresentaram baixos valores de casos e óbitos por 100.000 habitantes. Os resultados também indicaram que os maiores valores de casos e óbitos relacionados à Covid-19 estão fora das Regiões Metropolitanas brasileiras, evidenciando uma disseminação desse vírus para os municípios do interior.

Authors: Junior Jalme Santana de Figueiredo , Mormul Najla Mehanna , Leme Rosana Cristina Biral
Published: January 2022

No decorrer de 2018 à 2019 foi realizado um estudo de caso, junto aos professores de Geografia, pertencentes ao Quadro Próprio do Magistério (QPM) do Estado do Paraná, atuantes no Município de Francisco Beltrão. O principal objetivo foi identificar quais concepções de Educação Geográfica orientavam as práticas docentes desses profissionais. Partindo de uma perspectiva de pesquisa qualitativa, desenvolveu-se questionários e entrevistas junto 29 (vinte e nove) de um total de 35 (trinta e cinco) professores efetivos. Pode-se identificar três categorias centrais: Materialismo Histórico e Dialético, Histórico Ambiental e Subjetivo/Fenomenológico. Nesse texto, será apresentado os procedimentos e referências utilizados na pesquisa, que possibilitaram identificar uma prática docente pautada no compromisso teórico, prático e de transformação social por parte dos profissionais entrevistados.
Characteristics of leadership styles of students of the University of Donja Gorica
Authors: Bačanac Ljubica
Published: January 2022

The research performed on a sample of 210 students of the University of Donja Gorica (UDG), Podgorica, Montenegro, aimed to determine their leadership profiles' characteristics and examine the possible connection and the impact of selected demographic variables on its manifestation. In accordance with the total transformational leadership of Bass and Avolio, the Multifactor Leadership Questionnaire (MLQ-5X, self-rated version) was applied to measure the components of transformational, transactional, and laissez-faire leadership. The results of descriptive, comparative (t-test and ANOVA) and correlational analysis of the obtained data showed that the leadership profiles of UDG students are characterized by high scores for the transformational leadership factors (individual consideration, charisma, inspirational motivation, and intellectual stimulation), also followed by high scores for the contingent reward factors and management by exception - active related to transactional leadership, but with lowest scores for management by exception - passive and laissez-faire leadership. Such a leadership profile with predominant transformational qualities makes a good base for future leadership effectiveness. The results of the impact of demographic variables (gender and playing sports) were discussed in the context of their consistency/ inconsistency with the findings of previous research, theoretical and practical implications, and, specifically, regarding current policy and vision of UDG, entirely compatible with strategies used by efficient transformational leaders.
