Background: Nanoparticles (NPs) have recently attracted extensive attention in the field of elimination and reduction of microbial load in various water resources. Accordingly, this study aimed to eliminate bacterial contamination from aqueous solutions using synthesized NPs. Methods: In the present study, zinc oxide (ZnO) and silver (Ag) ion-doped zinc oxide (Ag/ZnO, 1-6 wt%) nanoparticles were synthesized using the sol-gel process and then characterized in terms of structure, morphology, and antimicrobial activity. X-ray diffraction (XRD) was utilized to determine the nanoparticle size and crystal structure. Images from field emission-scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) confirmed the successful production of NPs. The antimicrobial activity of ZnO and Ag1-6%/ZnO against Staphylococcus aureus and Escherichia coli was assessed by the agar well diffusion method. Results: According to the findings, the synthesized ZnO had a hexagonal structure and the size of ZnO and Ag5%/ZnO were 32.56 nm and 12.81 nm, respectively; the field emission-scanning electron microscopy (FE-SEM) images showed that the nanoparticle sizes were 77.60 nm and 47.15 nm, respectively. Based on transmission electron microscopy (TEM) images, the mean size of ZnO and Ag5%/ZnO was 22.5 nm and 17.5 nm, respectively. The results showed that the diameter of the zone of inhibition created by Ag5%/ZnO at a concentration of 0.1 g/mL was 20 mm and 13 mm for S. aureus and E. coli, respectively. Conclusion: The results indicated that E. coli was more resistant than S. aureus, although E. coli was still more resistant at low concentrations.

Newly emerged SARS-CoV-2 virus has been identified in China since 2019 and is still progressing as a tense threat to the human health worldwide. This virus can cause an acute respiratory infection and lead to death under acute circumstances. To describe the environmental factors affecting the prevalence of the disease as well as make an appropriate health strategy, some databases were reviewed. Coronavirus is mainly transmitted by direct contact through respiratory droplets. It can also be transmitted through secondary routes such as air, close contact and contaminated surfaces. The transmission through food has not been conclusively proven, but there are concerns about the food preparation, storage, infected staffs and improper use of personal protective equipment as the source of infection. Some possible sources of transmission are the contaminated water and sewage, especially in the areas where patients have the symptoms of diarrhea and vomiting. In this study, we described the essential strategies in order to prevent the spread of COVID-19 disease. Based on the most important criteria, this study developed a prevention model and health strategy including updated training information, improvement programs, risk assessment, environmental monitoring, operational measures as well as supportive approaches and programs, which can be used step by step to reach a healthy environment, increase the compliance with protocols and, eventually, decrease the incidence of COVID-19.

Background and Aim: Hypertension is a significant risk factor for cardiovascular disease and is the leading cause of death worldwide. The nursing process based on the Roy adaptation model is widely used to solve the problems caused by chronic diseases. This study aimed to adapt the model performed on patients with hypertension. Materials and Methods: The study was conducted in the autumn of 2021 in one of the hospitals of Qom University of Medical Sciences, Qom City, Iran. A patient with hypertension was examined, and a Roy model was performed on him. Nursing care was performed based on the Roy nursing process in 6 stages. Results: The study showed that the patient had maladaptive behaviors in four modes (physiological needs, adaptation of self-concept, role function, and independence and dependence). After nursing care based on the Roy adaptation model, maladaptive behaviors decreased. Conclusion: According to the present study results, nursing care based on the Roy model can affect the physical, psychological, and maladaptive behaviors of patients with hypertension. In this regard, Nurses can play a more effective role in improving the maladaptive behaviors of these patients by applying nursing care based on the adaptation model.

Background and Aim: Recent research has shown that microRNAs (miRNAs) can be regarded as new biomarkers for metabolic and angiogenesis-related diseases. This study aimed to investigate the effect of 8 weeks of resistance training on the expression of miRNAs associated with adipose tissue angiogenesis in rats with a high-fat diet. Materials and Methods: Forty male Wistar rats were randomly divided into four groups (each with 10 rats): normal diet, normal diet+resistance training, high-fat diet, and high-fat diet+resistance training. The resistance training groups performed 5 sessions of resistance training protocol each week for 8 weeks. After one week of familiarity with ladders, in the 2nd week, weights of 30% of body weight were attached to the rats’ tails, which gradually reached about 180% of their body weight by the end of 8 weeks. To evaluate the effect of resistance training and a high-fat diet on miR-221, miR-222, miR-329, and vascular endothelial growth factor (VEGF) variables, sampling of mesenteric adipose tissue was performed immediately after killing the animals. Results: The levels of miR-221, miR-222, and VEGF in the resistance training group+normal diet and resistance training group+high-fat diet increased significantly compared to the control groups (P=0.001, and P=0.001, respectively). However, no significant difference was observed in any groups regarding miR-329 (P=0.103). Conclusion: The results showed that resistance training increased microRNAs levels associated with adipose tissue angiogenesis in rats on a high-fat and normal diet.

Published: February 2023

Background and Aim: Pulmonary embolism because of hydatid cysts is a very uncommon and lethal complication caused by a hydatid heart cyst rupture or a visceral hydatid cyst released into the venous circulation. By utilizing contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI), hydatid pulmonary embolism can be differentiated from other types of pulmonary embolism. MRI mainly displays the cystic nature of lesions better than CT. Pulmonary embolism should be kept in mind in patients with hepatic hydatidosis if there is a sudden occurrence of chest pain and dyspnea, particularly in regions where hydatidosis is endemic. This report aims to present the clinical and radiographic features and discuss the diagnosis and treatment procedure of our patient. Case Presentation: Here, we report a 45-year-old man with pulmonary embolism as a consequence of a ruptured hydatid liver cyst in the inferior vena cava. Multiple intra-arterial pulmonary hydatid cyst emboli originating from a hepatic hydatid cyst ruptured into the hepatic portion of the inferior vena cava were seen in our patient. The patient refused the surgical treatment. Therefore, the patient was treated using Andazol (Albendazole) and Cetirizine hydrochloride. Conclusion: The present case is interesting because pulmonary embolism caused by hydatid cysts is a very uncommon clinical entity. There may be difficulties in diagnosing and treating hydatid cysts, and a definitive diagnosis was possible only by a histopathological examination.

Background and Aim: Angiogenesis is the most important foundation of exercise-induced hypertrophy. This study aimed to investigate the effect of 8 weeks of different muscle tension training on some microRNAs related to angiogenesis and muscle hypertrophy in bodybuilders. Materials and Methods: The present study is a quasi-experimental study with a pre-test-post-test design. The study groups included resistance training group 1 (10 people), resistance training group 2 (10 people), and the control group (10 people). The study subjects were selected from male bodybuilders who have done regular training for at least three years and are aged between 25 and 30 years. The study was explained to them, and 48 hours before and after the test, 5 mL of blood was taken from each sample. Descriptive statistics, including Mean±SD, charts and tables, and inferential statistics, including analysis of variance (ANOVA) and post hoc test, were performed using SPSS software. First, the Kolmogorov-Smirnov test was used to determine the normality of the data. Then, to compare the differences between the groups, the ANOVA was used, and if it was significant, the Bonferroni post hoc test was used. Results: This study showed that resistance groups 1 and 2 significantly increased miR-1 in bodybuilders. Also, group 1 had a greater effect than resistance group 2. The results showed that resistance training in different time points and sets had different effects on molecular pathways of hypertrophy. So, two hours after resistance training, mir-1 levels did not increase significantly, but 4 hours after resistance training, the levels of these microRNAs increased. This study showed that group 1 had a more significant effect on miR-206 levels than resistance group 2. Conclusion: The results of this study indicated that resistance training significantly increases the vascular endothelial growth factor (VEGF) levels of bodybuilders. Also, the results showed that in group 2, an increase in VEGF levels led to a greater effect on angiogenesis in these samples.

Background and Aim: COVID-19 is an acute respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A few studies with conflicting results have been performed to evaluate the relationship between the use of angiotensin system inhibitors and COVID-19 outcomes. Therefore, this study was performed to compare the clinical and paraclinical characteristics of patients with COVID-19 in two groups of patients treated with angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) and the control group (no history of ACEIs/ARBs) in Kamkar and Shahid Beheshti hospitals in Qom City, Iran from March 14, 2019, to the end of September 21, 2020. Materials and Methods: This retrospective descriptive study was performed by reviewing the medical record of 359 patients with COVID-19, which was confirmed by a physician via lung scan or reverse transcription polymerase chain reaction (RT-PCR). We used the independent t test to compare quantitative variables and the Chi-square test to analyze qualitative variables. Results: The common clinical symptoms, number of hospitalization days, oxygen saturation, and lung involvement were not significantly different between the two groups. Weakness, nausea, and sweating were significantly reduced in the control group compared to the ACEIs/ARBs group (P<0.05). Regarding the biochemical study, the patients’ hemoglobin levels and lymphocyte count on the first day of hospitalization in the ACEIs/ARBs group were significantly lower than the control (P<0.05) Conclusion: These findings do not provide evidence of adverse or beneficial effects of angiotensin system inhibitors, so we require more detailed studies with a larger sample size.

Algorithm for Decomposition of Integers and Smooth Approximation of Functions
Authors:   Vinnytsia National Technical University, Abramchuk Vasyl , Ihor Abramchuk Ihor ,   Vinnytsia National Technical University
Published: February 2023

The problem of expansion in powers is generalized into decomposition of positive integers in the sequence of degrees of different orders, the con-ditions of decomposition are determined, and the algorithm for decomposi-tion is constructed. The algorithm is based on two procedures: 1) achieve-ment a minimum of residual at each algorithm step; 2) speeding of decom-position through expanding the local base by reducing decomposition in-dex, which ensures finiteness of algorithm. The algorithm has such effi-ciency factors as high rate of decomposition, ease of implementation, availability of different options for the decomposition of numbers as in ex-tended, narrowed, sparse bases, which protects the encoded information from external influences. The algorithm can be used to encode large amounts of digital information under basic systems of small dimensions. Decomposition of positive integers into a sequence of powers is opti-mal and correct. Optimality of decomposition follows from the condition that at each step of algorithm the minimum value of disjunction in the space of mixed parameters x∈N,y∈Ris achieved. Correctness of algo-rithm is due to the fact that when the disjunction is reduced, the algorithm expands the basis of decomposition by reducing the degree indicators by one. By switching from a discrete model to a continuous model by replac-ing the degrees with power functions, we obtain a smooth approximation of the ill-conditioned function in the neighborhood of decomposition. The construction of posinomial polynomials on the basis of smooth polynomi-als is one of the promising directions of integration of ill-conditioned non-differentiable functions and smooth replacement of variables in the catas-trophe theory.Posinomials (functions with a variable exponent) predict the step of splitting the integration interval into parts, since they determine the loga-rithmic rate of change of an arbitrary monotonic function. The method of decomposition of positive integers provides an optimal decomposition into the sum of powers, and therefore the transition from a discrete model to a continuous model in the neighborhood of decomposition by replacing powers with power functions as well as allows to achieve the high accura-cy of approximation.
Boundary Value Problem with Soft Boundaries for Parabolic-Type Equations with Bessel-Euler-Legendre Operators on a Segment of a Piecewise Homogeneous Polar Axis
Authors:   Khmelnytsky Cooperative Trade and Economic Institute, Moroz Volodymyr
Published: February 2023

Composite materials are widely used in a variety of technological process-es, building, energy saving, in connection with which there is a need to pose and solve problems of thermal conductivity in environments that are heteroge-neous in their structure (multilayer bodies). At the same time, the heterogeneity of the medium leads to the consideration of boundary value problems with piecewise continuous or piecewise constant coefficients [3] and differential op-erators of the Bessel, Euler, Legendre, and Fouriertype, which model the het-erogeneity of the medium in terms of a geometric variable.In the classical setting, the processes of heat propagation were studied under the assumption that the boundary of the medium is rigid in relation to the reflection of waves. However, if we assume that wave absorption can occur at the boundary of the medium (soft boundary), we obtain a boundary value problem containing a time derivative in the operators of boundary conditions and conjugation conditions of the form (1).The analytical solution of the corresponding boundary value problem can be obtained using integral transformations with a spectral parameter, which work for problems with soft boundaries according to the same logi-cal scheme as integral transformations without a spectral parameter in problems with hard boundaries.This paper is devoted to the construction of one class of such hybrid in-tegral transformations generated by a hybrid differential operator of the Bessel-Euler-Legendre type on the polar axis.In this article an integral image of the exact analytical solution of a mixed problem for parabolic equations on a three-complex segment of the polar axis with soft boundaries is obtained by the method of a hybrid inte-gral transformation of the Bessel-Euler-Legendre type under the assump-tion that the boundary conditions and conjugation conditions contain a de-rivative with respect to the time variable

The nature of phase equilibria in the Cu3SbS3-CuI binary system over the entire concentration range were studied by means of the powder X-ray diffraction analysis (PXRD) for the first time at room temperature. It was found that the sample containing 66.7 mol.% CuI composed of a single phase and has a powder diffraction pattern completely different from the constituent phases of the system under study. The crystal lattice type and parameters, that were determined on the basis of the X-ray diffraction pattern of this sample using the TOPAS 4.2 and EVA computer programs are fully consistent with the literature data of the Cu5SbS3I2 four-component compound. The copper (I) iodide rich samples of the system consist of a two-phase mixture of Cu5SbS3I2 and CuI phases. However, the system is unstable in the Cu5SbS3I2-Cu3SbS3 composition range. In this concentration interval, the system is characterized by complex physico-chemical interaction of the initial components.

Based on the modern methods of SEM, voltammetry, and gravimetric analysis, samples of current collectors used in electrolyzers with a solid polymer electrolyte, made of porous titanium with various degrees of etching in concentrated hydrochloric acid, were studied. A gravimetric study of the etching process of samples of various sizes from porous titanium showed that throughout the process there is a loss of mass of the sample, with the exception of two short intervals, presumably due to the formation of hydrides (60-80 sec) and oxides (4-5 min), and the samples of smaller volumes were more sensitive to weight loss and weight growth. The use of the SEM method made it possible to reveal that etching over different time intervals changes the structure of porous titanium, reducing the average particle size and increasing their porosity .In this case, the surface inhomogeneity increases due to the formation of cavities in titanium and deterioration of the contact of the current collector surface with the catalytic layer. The consequence of this is the difference in the current-voltage characteristics of electrolysis cells with different duration of etching of the current collectors: there is a decrease in the productivity of electrolysis with an increase in the duration of etching of the current collectors by ~8% for etching more than 1 minute and ~18% for etching more than 4 minutes as compared to the simultaneous immersion of the sample in acid to clean the surface.

By free radical addition of ethanedithiol to alkyl- and cycloalkyl-substituted methylene dioxolanes, the bis-adducts tested then as a plasticizer for PVC have been obtained. It has been established as a result of the carried out investigations that the introduction of the synthesized compounds into PVC composition improves the physical-mechanical properties, which has been connected with the availability of sulfur atoms, carbonyl groups and ether bond in the molecules of bis-adducts. The high operational indices from PVCplastics indicate good plasticizing properties of the synthesized bis-adducts, and therefore they can be recommended for practical use.

Authors:   Zhytomyr Polytechnic State University, Dzhyhora Olha
Published: February 2023

The article examines the prerequisites for carrying out agrarian and land reforms, which are based on the restoration of human-nature ties. Regulatory documents regarding the competence of councils in the field of land relations were considered. The features of three stages of land reform in Ukraine are analyzed. It was determined that as a result of the land reform in Ukraine, the state lost its monopoly on land. In addition, a significant result of the land reform measures was the state's relinquishment of the monopoly on land resources in favor of private ownership. The most important goals of land reform in Ukraine are considered. The achievements and shortcomings of the land reform are studied. The activities of land market infrastructure institutes (State Land Bank, State Land Fund) were considered. The need to improve the institutional support of land reform in Ukraine is indicated, namely: the liquidation and formation of a new system of institutions and the structure of land management bodies and land relations in the country are necessary. It was determined that reforming the agrarian sector is an integral component of the transition of the country's economy to market relations. New problems related to the improvement of land relations in Ukraine and the formation of an economically efficient and ecologically safe land use system, especially for rural areas, are outlined. The level of development of the existing institutional support for the formation of the rural land use system is analyzed. The state of institutional support for the regulation (administration) of land relations and the organization of land use and protection was assessed as unsatisfactory. A logical-semantic model of the market-adapted system of the land system of Ukraine is presented, divided by blocks: natural-ecological, administrative-territorial, by forms and economic relations of land ownership, economic.

Invasive species threaten biodiversity all around the world and for this reason, identifying the causes and mitigating their effects is a priority in conservation biology. One of the most important factors when dealing with invasive species is dispersal, because the distribution of dispersal distances among members of a population can greatly affect the rate of spread of these invasive populations. Long distance dispersal events have a disproportionately large influence on dispersal kernel estimations, but because of restricted spatial sampling scales they are difficult to detect. Here we use an extensive database of 3,114 monk parakeets ringed in Barcelona city since 2002 as part of an extensive control program across Catalonia where 3,460 birds have been captured since 2013. Our aim was to describe these long–distance movements of monk parakeets. We recorded dispersal distances of over 10 km for a total of eight individuals. Long–distance dispersions were in all directions and both males and females were involved. While some individuals moved in their first year, others delayed dispersal several years. Given that long–distance dispersal events can have a large influence on the rate of range expansion of invasive species this information can be of great utility when modeling the dispersal and spread of the species.

Authors: Copado Rodríguez Ana Elizabeth
Published: February 2023

El artículo que se presenta desarrolla la perspectiva teórica sobre la evaluación formativa en educación virtual, trabajo de investigación asociado a tesis para obtener el grado de Doctora en Educación que otorga la Universidad Autónoma de Tlaxcala. En la presente investigación el objeto de estudio es someter a revisión teórica el proceso de evaluación formativa en educación virtual, el planteamiento central que orientó la investigación fue “¿Cuáles son las formulaciones teóricas de la evaluación formativa en relación con la retroalimentación y el aprendizaje autónomo en educación virtual?”. Se discutieron las categorías de análisis: a) perspectiva teórica: sajona, francófona y mexicana, b) retroalimentación y c) aprendizaje autónomo. Metodológicamente se consultaron fuentes de información en idiomas español, inglés y francés de acceso abierto con fecha de publicación desde 1967 al 2022, de las bases de datos Google Académico, ERIC, EBSCOhost y Scopus. Con el apoyo en el sistema de gestión de referencias bibliográficas Mendeley se sistematizaron las investigaciones recopiladas para su análisis con el método de análisis documental. De 60 artículos revisados, se eligieron 37 para su análisis sistemático que permiten presentar los hallazgos sobre las aproximaciones teóricas de la evaluación formativa en relación con la consecución del desarrollo de la autonomía que posibilita al estudiante el desarrollo de habilidades cognitivas y metacognitivas que le motivan para continuar aprendiendo, se presentan reflexiones que se aproximan al logro del aprendizaje autónomo, y permiten afirmar que hay una experiencia positiva en la implementación de la evaluación formativa en ambientes virtuales.
The Impact of Authoritarian Coaching Styles on Athletes’ Anxious States
Authors: Hagerty Shiloh , Felizzi Marc
Published: February 2023

The competitive nature of sports can exacerbate an athlete’s anxiety state. Anxiety may impact an athlete’s cognitive and behavioral functioning, which in turn affects their performance. Athletes handle an increased amount of pressure and can be affected by an emotionally abusive or authoritarian style of coaching. Self-determination theory can serve as the underpinning for  two different coaching styles, authoritarian and autonomic-supportive, that can impact an athletes’ anxiety. An autonomy-supportive coaching style may reduce athletes’ anxiety and enhance the athlete’s wellbeing and athletic performance while an authoritarian style can induce and sustain athletes’ anxiety symptoms. Social learning theory provides awareness of how coaches internalize styles of coaching and offers interventions that can be used to instill a positive coaching style with athletes. Sport social workers hold unique qualities to provide effective interventions at the micro and macro level. At the individual level, sport social workers can utilize evidence-based interventions including CBT and mindfulness to reduce anxiety symptoms and teach coping skills. At the organizational level, sport social workers can provide education and awareness of mental health and teach autonomy-supportive coaching. Sport social workers are an integral factor to assuring a safe, positive environment in the athletic arena.

Cuando concebimos este proyecto editorial, pensamos más bien en una obra paralela y distinta a los informes de cierre tradicionales, que mostrara desde un conjunto de miradas diversas cómo se percibió el trabajo de la universidad durante el periodo referido y cuáles son nuestras posibles áreas de oportunidad. Esta perspectiva entraña una novedad con respecto a otros ejemplares producidos como Memorias al final de un periodo administrativo: tomamos el riesgo de que fuesen otras personas –y no el equipo de Comunicación de Rectoría– las que escribieran aquí lo que desearan, con respecto a un puñado de temas propuestos; a saber: el trabajo de la uaa en materia de compromiso social y derechos humanos, en materia de fortalecimiento de la calidad académica, en las principales labores de gestión y en relación con la defensa de la autonomía universitaria. Para el proyecto invitamos a más de una veintena de personas –de dentro y fuera de la uaa– especialistas en temas de educación, derechos humanos, gestión administrativa e infraestructura. De ellas respondieron y nos entregaron colaboración 15, a quienes les estamos muy agradecidos por haberse tomado el tiempo de reflexionar sobre esta casa de estudios y dejar la impronta de sus miradas.
La industria de la madera en las economías del APEC: una propuesta metodológica para la construcción de un Índice de Productividad Sostenible
Authors: Navarro Chávez José César Lenin , Hernández Barriga Plinio , Trujillo García Claudia
Published: February 2023

Este trabajo tiene como objetivo proponer una medida para evaluar la productividad económica relativa a susefectos en el medio ambiente. Se propone un Índice de Productividad Sostenible (IPS) compuesto por el productode un índice de productividad y una Razón de Regeneración Ambiental (RRA), construido con información de labiocapacidad y la huella ecológica. El índice propuesto se emplea para evaluar la industria de la madera en laseconomías del APEC de 1990 a 2019. Los resultados indican que Corea del Sur, Singapur y Japón muestran unaRRA inferior a la unidad, con pérdida global de sus recursos forestales, lo que significa que su IPS es inferior a suíndice de productividad, mientras que para el resto de las economías los resultados son favorables, sin embargo, laRRA y el IPS decrecen en el caso de Nueva Zelanda y México.
