Published: June 2023

In an ever-evolving world, countless fresh methods for reflecting data are being developed. An image is used to illustrate. Compound images and data are widely used. Numerous photos that have been acquired contain noise, which impairs the image's qualities and produces visual disruption. Noise should be eliminated in order to preserve good image quality, as this helps the image restore its quality. Applying filters like the Median, Wiener, Gaussian, etc. can be used to remove noise from an image. This essay discusses Gaussian noise, salt-and-pepper noise, speckle noise, and filters including Mean, Median, and Gaussianfilters.

Published: June 2023

The sales of houses are influenced by various factors such as location, area, population, and other relevant information. Predicting individual housing prices can be instrumental in estimating future real estate prices. This study employs the Random Forest algorithm, a machine learning technique, as the primary methodology for developing a housing price prediction model. By focusing on the Random Forest algorithm, this project aims to optimize prediction accuracy and consistency, considering it as the best model for price prediction. The implementation of this project involves using Python (AI/ML) for coding the Random Forest algorithm, while HTML, CSS, and JS are employed for designing the system's frontend. Ultimately, the House Price Prediction system proves to be a valuable tool for accurately assessing property prices and maintaining a record of price fluctuations, promoting transparency and discouraging fraudulent activities.

A Bio-Thermal Convection in a Porous Medium Saturated by Nanofluid Containing Gyrotactic Microorganisms Under an External Magnetic Field

Published: June 2023

The study of thermal convection in porous media saturated by nanofluid and microorganisms is an important problem for many geophysical and engineering applications. The concept of a mixture of nanofluids and microorganisms has attracted the interest of many researchers due to its ability to improve thermal properties and, as a result, heat transfer rates. This property is actively used both in electronic cooling systems and biological applications. Thus, the purpose of this research is to study biothermal instability in a porous medium saturated by a water-based nanofluid containing gyrotactic microorganisms in the presence of a vertical magnetic field. Given the presence of an external magnetic field in both natural and technological situations, we were motivated to perform this theoretical research. Using the Darcy-Brinkman model, a linear analysis of the convective instability has been considered for both-free boundaries, taking into account the effects of Brownian diffusion and thermophoresis. The Galerkin method was used to perform this analytical study. We have established that heat transfer is accomplished by stationary convection without oscillatory movements. In stationary convection regimes, metal oxide nanofluids (Al2O3), metallic nanofluids (Cu, Ag), and semiconductor nanofluids (TiO2, SiO2) are analyzed. Increasing the Chandrasekhar and Darcy numbers improve system stability significantly, but increasing porosity and modified bioconvection Rayleigh-Darcy number speed up the beginning of instability. To determine the transient behavior of heat and mass transports, a non-linear theory based on the representation of the Fourier series method is applied. In small time intervals, the transitional Nusselt and Sherwood numbers exhibit an oscillatory character. The Sherwood numbers (mass transfer) in the time interval reach stationary values faster than the Nusselt numbers (heat transfer). This research might help with seawater convection in the oceanic crust as well as the construction of biosensors.

Exotic Structure of 17Ne-17N and 23Al-23Ne Mirror Nuclei
Authors: Mohammed Ruqaya A. , Majeed Wasan Z.
Published: June 2023

In terms of the core nucleus plus valence nucleon, shell-model calculations using two model spaces and interactions, the relationship between a nucleus' proton skin, and the difference in proton radii of mirror pairs of nuclei with the same mass number are investigated. In this work, two pairs of mirror nuclei will be studied: 17Ne-17N and 23Al-23Ne. For 17Ne-17N nuclei, p-shell and mixing of psd orbits are adopted with Cohen-Kurath (ckii) and psdsu3 interactions. While for 23Al-23Ne, the sd-shell and sdpf shell are adopted with the universal shell model (USD) and sdpfwa interactions. Also, the ground state density distributions, elastic form factors, and root mean square radii of these pairs' nuclei are studied and compared with available experimental data. . In general, it was found that the rms radius of the valence proton(s) is larger than that of the valence neutron(s) in its mirror nucleus. The results show that these nuclei have the exotic structure of a halo or skin.

Published: June 2023

Trigonometric Rosen-Morse Potential is employed as a mesonic potential interaction. The extended Nikiforov-Uvarov method is used to solve the N-radial Fractional Schrödinger equation analytically. Using the generalized fractional derivative, the energy eigenvalues are obtained in fractional forms. The current findings are used to calculate the masses of mesons such as charmonium, bottomonium, and heavy-light mesons. The current findings are superior to those of other recent studies and show good agreement with experimental data as a result, the fractional parameter is crucial in optimizing meson masses.
Assessment of Explicit Models Based on the Lambert W-Function for Modeling and Simulation of Different Dye-Sensitized Solar Cells (DSSCs)
Authors: Yerima Jamu , William Dunama , Babangida Alkali , Ezike Sabastine
Published: June 2023

In this paper, the characteristic points were used as input data in five different explicit models based on Lambert W-function for the extraction of model parameters of three DSSCs. Moreover, these model parameters for given values of voltages were used to obtain the corresponding currents for the simulation of the DSSCs. The results show that the sign of the model parameter does not matter for methods that do not have series resistance and shunt resistance. However, when Rsh was negative the five-parameter single-diode model failed to yield good curve fit except when Rsh was neglected and four-parameter model used. Moreover, all the model parameters for DSSCs with bitter gourd dye were regular and yielded good curve fit for all the models. On the hand, DSSCs with Rsh values negative were handled with four-parameter model to obtain good curve fit. Thus, the sign of model parameter matters in simulation of DSSC using single-diode model.

Published: June 2023

Due to their unique photophysical and photochemical properties and high sensitivity to the beta-pleated motifs, cyanine dyes have found numerical applications as molecular probes for the identification and characterization of amyloid fibrils in vitro and the visualization of amyloid inclusions in vivo. In the present study the spectroscopic and molecular docking techniques have been employed to evaluate the amyloid sensitivity and the mode of interaction between the trimethine cyanine dyes and native (LzN) and fibrillar (LzF) lysozyme. It was found that the trimethine association with non-fibrilar and fibrillar lysozyme is accompanied by the changes in dye aggregation extent. The molecular docking studies between trimethine dyes and lysozyme in the native and amyloid states indicate that: i) trimethines tend to form the most stable complexes with deep cleft of the native lysozyme; ii) the dye binding with non-fibrillar protein is governed by the hydrophobic interactions, π-stacking contacts between aromatic or cyclopentane ring of the cyanine and Trp in position 63 or 108 and hydrogen bonds between the OH-groups of the trimethines and acceptor atoms of Asp 101 (AK3-7) and Gln 57 (AK3-8) of LzN; iii) cyanine dyes form the energetically most favorable complexes with the groove Gly 2-Leu 4/Ser 8-Trp 10 of the lysozyme fibril core; iv) cyanines-LzF interaction is stabilised by hydrobhobic contacts, π-stacking interaction and hydrogen bonds. The dyes AK3-7, AK3-5 and AK3-11 were selected as the most prospective amyloid probes.

Published: June 2023

Cherry tomatoes are vulnerable to loss their marketability under high storage temperature causing rapid fresh weight losses and other quality changes. Surface coating using shellac, wax and alike is one of the postharvest management practically implemented to mitigate such undesirables. The present research was undertaken to study the effects of the coating material made from Taengwood Balu (Shorea obtusa) resin (TB resin) on respiration rates and effective skin permeance to water vapor of the cherry tomatoes stored at 10-35°C. Experiment findings show that the TB resin could be transformed into the coating material providing reasonable surface adherences as well as glossiness. Both respiration rates and the skin permeances of either TB resin coated or non-coated (control) tomatoes exponentially increased in relation to increasing temperatures. The relationship was well described by the Arrhenius model, of which values of root mean square of errors were in a range of 0.012-0.030. The TB resin coated tomatoes had approximately 2-fold lower values of both respiration rates and effective skin permeance, compared to those of the controls. In all, the experimental results highlight possibilities to utilize TB resin as an alternative surface coating material, together with low storage temperature for delaying losses of water vapor, a main contributor of fresh weight loss, and those of storage qualities related to respiration processes.

Anthropogenic Worlds of Transformation and Destruction: Doris Lessing’s Climate Fiction Duology
Authors: Baysal Kübra
Published: June 2023

Depicting a world stricken with an ice age in the North and drought in the South, Doris Lessing’s Mara and Dann: An Adventure (1999) recounts the survival story of two siblings, Mara and Dann, amidst un/natural and societal havoc. The sequel, The Story of General Dann, Mara’s Daughter, Griot, and the Snow Dog (2005) pictures the dramatic transformations both in the nonhuman nature and the protagonists’ lives after the devastating disasters in the first novel. Migrating among thousands of people from the south towards northern Ifrik and passing through desolate lands scorched with drought, 4re, 3ood, and diseases in Mara and Dann, the protagonists mature as they learn to live in a perilous and erratic world populated with survivalists solely focused on personal gain. Through the horrendous picture of an Ifrik parched with drought in the South and frosted with a solid layer of ice at the top north, the novel pictures the helplessness of humankind through Mara and Dann’s quest for life in the face of unstoppable and inevitable environmental calamities. With the melting of the ice in the Northern Yerrup and the flooding in the Northern Ifrik, General Dann delivers Dann’s struggle to cope with his personal loss as the world changes once again, and the climate gets cooler. Obsessed with knowledge and set on to save a library, he races against time, human beings, and the hostile nonhuman environment. In this light, this study aims to analyse Doris Lessing’s climate fiction (cli-fi) duology, Mara and Dann: An Adventure and General Dann and Mara’s Daughter, Griot, and the Snow Dog as climate fiction novels reflecting the destructive impact of climate change on humans and nonhuman nature in the anthropogenic conditions of the fictional world, which is not a far cry from our world in the twenty-first century.

The results of the studies of quails kept on diets using subcutaneous fat of pigs bred in Siberia in feed additives, different in morphological, chemical composition, as well as organoleptic qualities, are presented. The following parameters were studied: growth rate, viability, egg laying rate, biochemical blood characteristics (triglycerides, total cholesterol, high-density lipoproteins, low-density lipoproteins, atherogenic index, free radical oxidation and antioxidants levels). The following breeds were studied: Kemerovo (K) and Pietrain (P) and their fat. In breed K, the fat thickness was 35.1 mm; in breed P, 21.1 mm, saturated fatty acids (SFA) in fat were 41.56 and 38.28%, respectively, polyunsaturated fatty acids (PUFA) - 15.18 and 19.42%, linoleic acid 15.08 and 19.22%, cholesterol 0.16 and 0.26%. The organoleptic qualities of the fat were 3.9 and 2.4 points, respectively. The fat of these pig breeds, as well as sunflower oil (control), was added to the feed of quail chickens of three groups of 60 individuals each up to 23 weeks of age (3.0 - 3.5% of the weight of the diet). The quails that received K-breed fat grew faster, they had higher egg production, and the average egg weight. In the quails treated with fat of breed P containing a high level of total cholesterol, rich in PUFA and linoleic acid, there were significantly more low-density lipoproteins in the blood serum (44.9 ± 9.01mg / dl versus 29.0 ± 5.51 in group K and 28.6 ± 4.81 in the control), higher peroxidation lipids and the highest atherogenic index. The data obtained indicate that the fat of breed K is more useful for animal nutrition than the fat of pigs of breed P and may be a priority in human nutrition. This provides the basis for testing and confirming the results obtained in humans, as well as for pig breeding in the direction of improving the fatty acid composition of meat and fat in the direction of increasing the concentration of saturated fatty acids.

Published: June 2023

The results of the studies of conifers as a material for landscaping of settlements, and as an accent and dominant in decorative compositions or in mono-planting are presented. The expansion of coniferous plant assortment for landscape construction of southern Russia in the 2000s was noted due to the introduction of crops from other regions with different natural and climatic conditions. Newly planted crops are under stress, which has a negative effect on the immune status of the introduced plants. The results of the study of the species composition of sucking pests of coniferous plants in urban landscapes are presented. The world experience in the studies of urban landscapes shows the expansion of the species composition of pests from the order of homopterous insects (Homoptera). Phytosanitary monitoring of ornamental conifers in urban plantations and park areas in the Kuban zone of the central horticultural subzone of the Krasnodar Territory in 2012-2022 was conducted. As a result of these studies, the species diversity of sucking pests of coniferous plants in the region has been identified, their ranking by the type of feeding has been carried out, and a database is being compiled. It has been found that the dominant representatives of the superfamily Coccidae in the region are: European juniper scale insect (Carulaspis juniperi Bouché) and yew pseudo scale insect (Parthenolecanium pomeranicum Kawecki), and pine spindle scale insect (Anamaspis lowi Colvee). The regularities of food specialization of scales are of not only theoretical but also practical importance. Based on the research, the probable composition of pests on a newly introduced crop can be predicted. The resulting patterns are one of the theoretical foundations of pest control measures.

Background

The risk of SARS-CoV-2 (re-)infection remains present given waning of vaccine-induced and infection-acquired immunity, and ongoing circulation of new variants.

Aim

To develop a method that predicts virus neutralisation and disease protection based on variant-specific antibody measurements to SARS-CoV-2 antigens.

Methods

To correlate antibody and neutralisation titres, we collected 304 serum samples from individuals with either vaccine-induced or infection-acquired SARS-CoV-2 immunity. Using the association between antibody and neutralisation titres, we developed a prediction model for SARS-CoV-2-specific neutralisation titres. From predicted neutralising titres, we inferred protection estimates to symptomatic and severe COVID-19 using previously described relationships between neutralisation titres and protection estimates. We estimated population immunity in a French longitudinal cohort of 905 individuals followed from April 2020 to November 2021.

Results

We demonstrated a strong correlation between anti-SARS-CoV-2 antibodies measured using a low cost high-throughput assay and antibody response capacity to neutralise live virus. Participants with a single vaccination or immunity caused by infection were especially vulnerable to symptomatic or severe COVID-19. While the median reduced risk of COVID-19 from Delta variant infection in participants with three vaccinations was 96% (IQR: 94–98), median reduced risk among participants with infection-acquired immunity was only 42% (IQR: 22–66).

Conclusion

Our results are consistent with data from vaccine effectiveness studies, indicating the robustness of our approach. Our multiplex serological assay can be readily adapted to study new variants and provides a framework for development of an assay that would include protection estimates.
MANAGEMENT OF AN ARCHIVE AS A CULTURAL HERITAGE OBJECT
Authors:   Belarusian State University, Hiarnovich Tatsiana D.
Published: June 2023

The main purpose of the article was to present an archive as an object of cultural heritage. Since the 19th century the concept of cultural heritage protection has been taking shape in philosophy and international law, which, in addition to architectural, museum and library objects, extends to archival collections. In the late 20th century the development of digital technologies contributed to the elaboration t of a new approach, which involved not only ensuring the safety, but also the availability of cultural property for all. For the effective implementation of new approaches, the cultural heritage protection policy is being replaced by the cultural heritage management paradigm. The management of a cultural heritage site must be carried out based on a specially developed Management Plan. The main aspects of documentary heritage management are regulated by the UNESCO Memory of the World Program. The management of an archive as an object of cultural heritage is carried out through the creation of the projects aimed at promoting information on archives and archival documents in society. The activities aimed at popularization of archives in the Republic of Belarus became especially urgent in connection with the implementation of the national plan of events for the Year of Historical Memory in 2022.

ARCHPRIEST SERGEI ANDREEVICH SAKHAROV. THE FATE OF A PRIEST UNDER CONDITIONS OF SERIOUS PERSECUTIONS AGAINST THE CHURCH IN THE 1930S
Authors:   Patriarchal Administration of the Moscow Metropolis of the Russian Orthodox Church, Grishin Alexander A.
Published: June 2023

The article presents the previously unpublished documents about the main stages in the life of Archpriest Sergey Sakharov during the political repressions of the Soviet regime in the 1930s. The purpose of the article is to trace the major milestones in life of a normal average clergyman at the time of repressions carried out by the Soviet government. Having before one’s eyes a detailed picture of the church-state relations in the 20th century, the life of an individual clergyman has often remained outside the field of historical research. At the same time, it is precisely the investigation into the life path of a “typical” rural priest that makes it possible to fully imagine the fate of many of his compatriots who completed their “journey” at the Butovo training ground in 1937. The article provides some brief biographical information about the life of Archpriest Sergei Sakharov until 1930, but the central part of the present paper is focused on the three successive arrests. Reconstructing them on the basis of the previously unpublished documents from the State Archives of the Russian Federation, the author identifies the distinctive features of those processes, depending on the gradual swinging of the repressive pendulum, and makes an attempt to envision the fate of the thousands of affected clergy through the prism of the personality of Archpriest Sergei Andreyevich Sakharov.

The article deals with an analysis of the possibilities of implementing a project for the digital integration of information resources (state information systems) that are currently being created by the federal government departments of the Russian Federation in charge of the Archival, Library and Museum Funds. In the preamble, the author briefly describes foreign experience in implementing such projects; highlights the history of the discussion – within the Russian communities of historians, culturologists, specialists in the field of information technology and security, as well as archivists, librarians and museum workers – of the issue of creating unified archive-library-museum information resources; defines the main goals that could be achieved as a result of the formation of integrated resources. In the main part of the article, the author considers the regulatory and methodological framework of the Archival, Museum and Library spheres in the context of the creation of the sectoral state information systems. The article also deals with the changes that have occurred in the regulatory and methodological framework over the past decades – the changes that are related to the adjustment of the activities for the acquisition, recording, keeping, use and provision of access to the information connected with the «non-core» objects of historical and cultural heritage included in the collections. The author pays special attention to the analysis of methodological and technical approaches, as well as to the solution of the technological issues (standards and formats), which form the basis of the created information systems. It is concluded that the creation of integrated information resources seems unlikely under the present circumstances.
Foros escucha: fracaso y olvido de la justicia transicional en el gobierno de Andrés Manuel López Obrador (2018-2024)
Authors: Galaviz-Armenta Tania
Published: June 2023

El trabajo se enfoca en analizar los elementos que condujeron al fracaso de los foros escucha para trazar la ruta de pacificación del país y la reconciliación nacional impulsados en el 2018 por el entonces presidente electo, Andrés Manuel López Obrador. Y el efecto negativo que este fracaso tuvo en la posible implementación de un proceso de Justicia Transicional en México. En este sentido, se emplea la Teoría de los Sistemas Sociales de Niklas Luhmann que permite analizar la forma en que los derechos de las víctimas se vinculan al sistema de derecho y, sobre todo, a la justicia transicional, y con ello, comprender los límites de los Foros Escucha. Se ha realizado una revisión bibliográfica, documental y hemerográfica del desarrollo de los foros, así como de la definición y evolución a nivel internacional de la justicia transicional y de los derechos de las víctimas. En los principales resultados destaca la contradicción de las expectativas que tenían las organizaciones y colectivos de familiares, las del equipo que organizaba los foros y las del presidente electo a la influencia tendrían para definir una política de reconciliación mediante la justicia transicional.
Programa de extensión de la jornada escolar en el estado de Tamaulipas como política para la inclusión y la equidad educativa

Published: June 2023

La evidencia empírica ha demostrado que la educación es un factor determinante para disminuir la desigualdad, de ello deriva la importancia de concebir un modelo educativo que pondere la equidad e inclusión como elementos esenciales. Desde esta perspectiva se han diseñado políticas educativas que buscan incrementar las oportunidades de aprendizaje, el logro académico y la eficiencia terminal. Derivado de ello, surgió en México el Programa Escuelas de Tiempo Completo (PETC) como una de las principales acciones para disminuir la desigualdad y fomentar la equidad educativa. Sin embargo, tras 15 años de su implementación, el PETC fue suspendido, generando un debate sobre las implicaciones que su cierre tendría. Ante este contexto, el presente documento tiene como objeto de estudio las primarias públicas con jornada extendida en el estado de Tamaulipas, las cuales son analizadas a partir de una metodología mixta, estableciendo como variables el logro educativo, contexto socioeconómico y administración escolar. Los resultados apuntan a que la extensión de la jornada escolar observa una relación indirecta con el logro académico, sin embargo, el impacto del programa trasciende los indicadores de aprendizaje y ofrece múltiples posibilidades para la mejora colectiva e individual de la población en edad escolar en situación vulnerable.
