DETERMINATION OF EXTERNAL IRRADIATION FROM SOURCES WITH COMPLEX GEOMETRY CONTAINING RADIOACTIVE WASTE
Authors: Rudychev Y. V. 
Published: December 2023

A combined technique using both Monte-Carlo and quasi-analytic method has been developed for calculation of irradiation from complex objects containing radioactive waste. Monte Carlo method is used to calculate spectral, angular and spatial distributions of γ-quanta close to one of the surfaces of the concrete cask loaded with containers filled with radioactive waste (RW). Radiation characteristics at the prescribed distance are determined by integrating the point sources with calculated distributions over thissurface. Summation of photons of external radiation from individual RW isotopes allows finding the photon flux for any storage time. Application of the technique allows to calculate asymmetric loading of casks with containers filled with RW of different activity and to optimize the arrangement of the casks in the RW storage area. This allows reducing the effect of radiation-absorbed dose on the service personnel and on the areas surrounding RW storage.

Squaraines represent a class of organic dyes operating in red and near-infrared regions. Due to their unique optical characteristics, such as high extinction coefficients, reduced background fluorescence and light scattering, photostability, these fluorophores attract ever-growing attention as prospective bioimaging agents. The present contribution overviews the spectral properties and some biological applications of the novel squaraine dye SQ-1. This probe was found to possess very high lipid-associating ability manifesting itself in a sharp increase of its emission. Binding of SQ-1 to the lipid bilayers containing zwitterionic and anionic lipids was found to be controlled mainly by hydrophobic interactions. Analysis of SQ-1 spectral behavior in the model membrane systems containing heme proteins revealed the dye sensitivity to the reactive oxygen species. This effect was supposed to originate from the reaction between lipid radicals and SQ-1 occuring at the squaric moiety or in its vicinity. Resonance energy transfer studies highlight the applicability of SQ-1 to structural characterization of amyloid fibrils.

In this paper, to obtain streams of thermal and epithermal neutrons are used delayed neutrons emitted from the target with a fissile material. The target preliminarily activated with help of electron beam from linear accelerator with an energy of 20 MeV and a power of 9 Watts. At the same time to obtain a stream of thermal as well as epithermal neutron density 6 10^-5 n / (cm^2 s) The results of experiment are presented where half-decay curves have been measured of emitting delayed neutrons radioactive nuclei produced in the fission process. It has been shown that the activated target, which contains the fissile material, presents a compact small size source of delayed neutrons. It can be delivered to the formator where thermal and epithermal neutrons are formed during a certain time period with help of the moderator, absorber and collimator. Then this target is moved to the activator being replaced with another target. Thus, pulsed neutron flux is produced. The duration of neutron pulse corresponds to the presence time of the activated target in the formator, and time interval between pulses is determined by the delivery time of the target from the activator to the formator. Given that the yield of neutrons from the target is directly proportional to the power of the beam of accelerated electrons, shows that the beam power of 1.5 - 3 kW, the flux density of thermal and epithermal neutrons can reach the values of (2-3) 10^9 n / (cm^2 s). Such a neutron beam can be used in nuclear medicine, in particular, in neutron capture therapy of oncologic diseases.

Published: December 2023

In this paper, we aim to describe the cosmic late-time acceleration of the Universe in f(R,Lm) gravity framework proposed by Harko (2010) with the help of an equation of state for strange quark matter. To achieve this, we adopt a specific form of f(R,Lm) gravity as f(R,Lm) =R/2}+ Lnm, where n is arbitrary constants. Here we utilize a hybrid scale factor to resolve the modified field equations in the context of f(R,Lm) gravity for an isotropic and homogeneous Friedmann–Lemaître–Robertson–Walker (FLRW) metric in presence of strange quark matter (SQM). Also, we analyze the dynamics of energy density, pressure and the state finder parameters and explained the distinctions between our model and the current dark energy models in the presence of SQM. We observed a transition from an accelerating to a decelerating phase in the Universe, followed by a return to an accelerating phase at late times. Also, we analyzed the state finder diagnostic as well equation of state parameter and found that the model exhibited quintessence-like behavior. The conclusion drawn from our investigation was that the proposed f(R, Lm) cosmological model aligns well with recent observational studies and effectively describes the cosmic acceleration observed during late times.

Due to the necessity of reducing the reliance on fossil fuels, several systems are considered to be alternative and/or additional support for the existing battery material. In this report, structural and electronic properties of aluminium oxide (Al2O3) and aluminium sulfide (Al2S3) with hexagonal symmetry (α-phase), are investigated by utilizing density functional theory technique based on r++SCAN functional. The calculated lattice parameter and insulating gap for both systems are well matched with previous experimental studies and display higher accuracy compared to the results from local density approximation (LDA) and generalized gradient approximation (GGA) studies. The calculated insulating gap values are 10.3 eV and 4.1 eV for α-Al2O3 and α-Al2S3 respectively. For α-Al2O3 system, we observed hybridized s-p-d orbital of Al-O in the conduction states, consistent with the interpretation of past X-ray Absorption Near Edge Structure (XANES) data. Finally, the bulk and young modulus for α-Al2O3 are determined to be 251 GPa and 423 GPa which is very close to the known experimental values of 280 GPa and 451 GPa.

Published: December 2023

The effect of thermal treatment on the behavior of samarium atoms introduced into silicon during the growth process was studied using the method of transient capacitive deep-level spectroscopy (DLTS). It has been shown that various high-temperature treatments lead to the activation of samarium atoms in the bulk of n-Si and the formation of deep levels. The energy spectrum of deep levels arising during heat treatments has been determined. The dependence of the efficiency of formation of these levels in n‑Si<Sm> on the processing temperature has been studied. It was found that the higher the content of samarium atoms in the bulk of silicon at the same high-temperature treatment temperature, the higher the concentration of the deep level EC–0.39 eV. From this, we can conclude that the EC–0.39 eV level is associated with the activation of samarium atoms in the n-Si<Sm> volume.

Two series of multilayer coatings with different numbers of bilayers (268 and 536, respectively) were synthesised using the cathodic vacuum-arc deposition (CVAD) with the simultaneous sputtering of two different cathodes. The first cathode was made of the multicomponent TiZrSiY material, and the second one was made of technical niobium. The coatings were condensed in a nitrogen atmosphere at a constant negative bias potential applied to the substrate. The resulting coatings have a distinct periodic structure composed of individual layers of (TiZrSiY)N and NbN with the thicknesses determined by the deposition interval (10 or 20 s, respectively). The total thicknesses of the coatings determined by the number of bilayers were 11 and 9 microns, respectively. The formation of polycrystalline TiN and NbN phases with grain size comparable to the size of the layers has been identified for both series of coatings. The layers exhibit a columnar structure growth with a predominant orientation (111). The hardness of the experimental coatings depends on the thickness of the layers and reaches 39.7 GPa for the coating with the smallest layer thickness. The friction coefficient of the obtained coatings varies from 0.512 to 0.498 and also depends on the thickness of the layers. A relatively large value of the friction coefficient is due to high roughness and the presence of a droplet fraction on the surface as well as in the volume of the coatings.

Published: December 2023

Now, in difficult economic conditions in Ukraine, the issue of effective cost management is becoming relevant for enterprises, taking into account the opportunities to stimulate resource savings, forecasting and controlling costs according to the “Expenses-output-profit” system.
Now in our country there is a question of ensuring the stable development of enterprises. First of all, this is due to the military aggression against Ukraine. Business has to resist internal and external negative processes taking place both in the state and outside it.
Entrepreneurs are increasingly in need of support and assistance from economically stable partners. The ability of an enterprise to effectively conduct economic activities is marked by the level of its costs and prime cost, which characterize its ability to provide such a level of financial stability sufficient to avoid the risks of bankruptcy and unprofitability of economic activity.
The above gives an opportunity for stable and dynamic development of Ukrainian enterprises. It is the choice of optimal aspects and methods of cost management that creates the basis for economic stability and competitiveness of enterprises in the world market. Market conditions are increasingly increasing the requirements for the efficient conduct of business activities and maximization of income. This can be achieved in two ways. The first is by increasing income (increase in product prices). The second is the cost optimization method.
It should be noted that in the context of automating the activities of enterprises in the world, the cost optimization procedure based on business process modeling is of particular importance. The issue of cost management in this context still needs a detailed study. Reliable cost estimates are essential for making the right decisions and taking the best action. Therefore, this task requires highly qualified employees of the company to master the techniques and methods of applying certain elements of the cost management structure to solve certain situations. Modern Ukrainian enterprises still need such employees.
In difficult economic conditions for our state, the introduction of more adapted to domestic conditions and the specifics of doing business is important methodologically, due to the need for uninterrupted monitoring of costs and support for the competitiveness of the enterprise.

Published: December 2023

En la actualidad la implementación de la tecnología en el ámbito educativo ha tenido diferentes visiones. Este estudio tiene como objetivo identificar el criterio de los diferentes autores sobre las implicancias de la tecnología en la educación. Se llevó a cabo una revisión bibliográfica realizada durante el periodo 2017 – 2022 en las bases de datos Scopus, Proquest , Redalyc y Scielo. Desde esta indagación se establecieron para el análisis 17 artículos que han permitido identificar aspectos relevantes a tomar en cuenta en futuras investigaciones. Como principales hallazgos se identificó que en las instituciones educativas rurales existe desigualdad en el acceso de herramientas tecnológicas en el aula de clases, la gran parte del personal docente no está capacitado sobre la pedagogía de la tecnología de la información y la comunicación. A su vez, el uso adecuado de las plataformas educativas mejora el aprendizaje de los estudiantes y contribuye a su formación personal, académica, profesional y laboral. En el campo de la educación, es imprescindible diseñar políticas de las TIC con la finalidad de disminuir la brecha digital y fomentar la inclusión y equidad en los establecimientos. Así mismo, la indebida utilización de los programas digitales resulta de la inflexibilidad del currículo y de las directrices actuales impuestas por el gobierno. Al contrario, el uso idóneo de estos aparatos depende principalmente de la capacitación y experiencia del maestro en la enseñanza–aprendizaje de estos

The success of planting in the field is influenced by the quality of the seeds used. The aim of this research is to evaluate the physical quality of eucalyptus seeds produced by the BPDAS Citarum-Ciliwung Nursery Center based on SNI 8420:2018. The quality assessment of eucalyptus seeds is carried out based on the requirements stated in SNI 8420:2018. The results of the evaluation of the physical quality of eucalyptus seedlings at the BPDAS Citarum-Ciliwung Nursery Center show that eucalyptus seedlings have passed the general requirements test for the origin of normal seeds and seedlings (woody stem criteria); and pass the test for special requirements. Eucalyptus seedlings did not pass the general requirements for normal seedlings for the criteria of straight stems and healthy seedlings. Eucalyptus seeds that do not pass the test can be retested after the seeds have been selected or the quality of the seeds has been improved. Improving the quality of seeds can be done by carrying out routine thinning activities in the nursery.

Authors: Martinez-Carvajal Lady Gabriela , Castañeda-Saavedra Stefanía de los Ángeles , Beltrán-Avendaño Mónica Andrea 
Published: December 2023

Introducción. La isoinmunización Rh consiste en la producción de anticuerpos maternos en una gestante Rh negativa contra los antígenos de los eritrocitos Rh positivos fetales ocasionados por una hemorragia fetomaterna. En población gestante, el 15% son Rh negativo y la severidad de la afectación fetal está relacionada con una serie de procesos inmunológicos y la historia obstétrica. Si una gestante Rh negativa con riesgo de isoinmunización no recibe profilaxis con inmunoglobulina Anti-D se inmuniza el 16% en la primera gestación, el 30% en la segunda y el 50% después de la tercera. Con este reporte de caso queremos describir el subgrupo de pacientes gestantes con isoinmunización Rh bajas respondedoras. Presentación del caso. G9P5C1A2Gem1V7 de 43 años, remitida en semana 30 de gestación por isoinmunización Rh, no recibió inmunoglobulina Anti-D durante este embarazo, ni en los anteriores ni en el posparto, reporte de Coombs indirecto de 1/4 que se eleva a 1/16, seguimiento ecográfico normal. En semana 35.3 presenta anemia fetal leve y por tratarse de un embarazo alrededor del término se finaliza por cesárea. Recién nacido con adecuado peso para la edad gestacional, quien fue dado de alta a las 72 horas con evolución satisfactoria. Discusión. Las gestantes con isoinmunización Rh bajas respondedoras se sensibilizan con altos volúmenes sanguíneos sin repercusión hemodinámica in utero, produciendo una enfermedad hemolítica fetal leve. Esta respuesta inmune es poco frecuente y está asociada a factores protectores; sin embargo, son necesarios más estudios que sustenten esta condición. Conclusiones. El control prenatal y el Coombs indirecto cuantitativo seriado son las principales herramientas para la prevención de la isoinmunización. El conocimiento de la respuesta inmunológica permite identificar el subgrupo de las bajas respondedoras que tienen una evolución clínica más leve y menor morbilidad neonatal.
