Published: December 2022

Today, an urgent problem in modern construction is the development of highly functional fire-resistant solutions to protect the timber from destruction and the effect of fire on it, which are characterized by the high efficiency of the penetration of these solutions into the middle of the timber, the durability of their protection and operational properties to ensure the longevity of the operation of timber structures. One of these fire-resistant solutions is a solution invented on the basis of the method of impregnation of timber based on area. In this work, we provide an analysis of modern methods of calculated tests regarding the quality of impregnation of timber structures and timber products made of timber with protective fire-resistant solutions (fire retardants), as well as the schemes of these model tests.

Published: December 2022

In this article on increasing the efficiency of steel combined structures, the tasks of rational design, regulation and control of structural parameters of elements, the use of steels with increased mechanical properties are considered. It is shown that for a six-span stiffening girder of a combined truss with elastic supports, which operates under a distributed load, the moment is 72 times smaller than the moment of a single-span beam. It is suggested to use high-strength steel for truss braces. Rationality criteria are proposed. On the basis of rationality criteria, new steel combined trusses were developed and their models were designed for stress tests. The results of experimental studies of models of combined trusses are presented. The results of experimental studies conducted on models of steel combined trusses qualitatively and quantitatively confirmed the theoretical results obtained on the basis of the proposed theory.

Currently, the problem of energy-saving construction remains extremely relevant. The application of thermorenovation measures for existing public and residential buildings is one of the ways to solve the problem of rational use of fuel and energy resources. In this article, one of the thermorenovation measures is considered, in particular, the installation of additional external insulation to insulate external walls on the example of a general secondary education institution. The results of the research made it possible to evaluate the thermal stability of the fences as a result of insulation, so it was established that gas consumption and gross carbon dioxide emissions when using insulation with a thickness of 150 mm is reduced by almost 4.5 times. The proposed thermoregulation measures bring buildings into compliance with state regulations and increase indoor comfort by equalizing the average temperature and eliminating cold bridges.

Studies of moisture loss from hardening monolithic cement concrete have been carried out. It was found that there is no consensus on the critical value of moisture loss from hardening concrete, at which shrinkage and cracking are possible, and there is no common understanding of the possible critical width of the shrinkage crack opening. It is shown that when the concrete hardens in air-dry conditions, its indicators, including durability, decrease by a factor of 2 or more. The critical value of moisture loss from hardening concrete was experimentally determined, which is 2 kg/m2. In this case, the deterioration of concrete properties as a result of rehydration of cement does not exceed 5 % and does not affect its durability. The possibility of restoring the properties of concretes, which were lost as a result of cracking during plastic shrinkage and contraction, has been experimentally proved if, after cracking, the concretes are placed for further hardening in a humid environment.
PROPERTIES OF FRESH AND HARDENED MORTARS WITH AIR-ENTRAINING AGENT
Authors:   Lviv Polytechnic National University, Department of Building Production, Markiv Taras
Published: December 2022

The influence of the air-entraining agent (AEA) on a density, the volume of entrained air of mortar mix and compressive strength of hardened mortar was studied in this article. Results show that the addition of AEA results in the reduction of water to cement ratio to provide the targeted flow and the density that depends on the volume of entrained air. The addition of AEA causes the decrease of the density of mortar (C:S=1:2) by 8,2% and the increase of the compressive strength by 13,9% after 28 days of hardening compared to the mortar (C:S=1:2) without AEA. The further increase of a sand content in a mortar (C:S=1:3) results in slight decrease of a density of fresh mortar and compressive strength. If C:S ratio is 1:4 the increase of the density and the compressive strength decrease is observed in comparison with the mortar with C:S=1:3. The obtained results show that properties of mortar incorporating AEA depend on its mix proportion.

This review examines the association between postpartum depression and breastfeeding in the context of studies published between 2015 and 2022. The goal of those studies was to determine the impact of depression on breastfeeding and vice versa. After conducting in-depth research on 15 studies that varied in location, population, and method of evaluation, a high degree of agreement was observed in their findings. Postpartum depression has a significant impact on breastfeeding percentages, whereas breastfeeding appears to improve the mother's psychological status and significantly reduce anxiety and depression symptoms. These findings emphasize the complex relationship between postpartum depression and breastfeeding and validate the need for additional research.

Published: December 2022

One in eight women worldwide will develop breast cancer in their lifetime. Obesity, physical activity, and dietary composition are known to influence the prognosis of breast cancer. There have been significant concerns regarding the toxicity of existing pharmaco- and chemotherapies, and additional complementary dietary and lifestyle interventions are suggested for breast cancer prevention.
This review aims to highlight current information regarding the association between dietary patterns and lifestyle with BC, including risk and prognosis. In addition, this article discusses dietary intake, physical activity, and other habits as lifestyle modification strategy targets.
The incidence of breast cancer is increasing at an alarming rate worldwide, making it the most prevalent malignancy in women. A significant relationship exists between obesity, physical inactivity, a sedentary lifestyle, dietary patterns, and breast cancer risk. Unhealthy lifestyle habits, such as smoking, alcohol consumption, and tobacco use, also contribute to this increased risk. Obese women who have a high risk of breast cancer had better metabolic and inflammatory profiles when they engaged in lifestyle activities and diet interventions that were tailored to their needs. Physical activity was linked with a reduction in cancer incidence and mortality risk. A decrease in an individual’s consumption of red meat, animal fat, and sugary foods, as well as their increased consumption of fiber, fruits, and vegetables, were associated with a reduced risk of breast cancer. Other modifiable risk factors, such as smoking cessation and the avoidance of alcohol and tobacco, contributed to breast cancer survival.
A healthy lifestyle that includes exercise and dietary modifications may serve as adjuvants to expedite breast cancer prevention interventions and optimize the health of cancer survivors.

Biblical Topos as Markers of the Author’s Style
Authors:   Lomonosov Moscow State University, Shoutova Lidia
Published: December 2022

This article presents a problem of delimiting parts of the Extensive Edition of the Life of St. Sergius of Radonezh, begun by Epiphanius the Wise and completed, as well as in places edited, by Pachomius Logofet. One of the methods of distinguishing the parts is to compare the principles of citing Biblical texts. The identification of allusions, quotations, toposes and biblicalisms makes it possible to oppose Epiphanian and Pachomian “scriptures” more clearly. This research reveals 7 new quotes in the preface to the Extensive Edition of the Life of St. Sergius of Radonezh in addition to 25 previously commented quotes. The preface to the Life of St. Sergius of Radonezh, to the life of Stephen of Perm, the author of which is Epiphanius the Wise, the preface to the Lifes of Nikon of Radonezh and Kirill Belozersky, written by Pachomius Logofet, were considered from the position of citation richness.

The scientific monograph “Literary Multilingualism in the Slovenian and Austrian Context” (2020) is a collective work of nineteen researchers from five countries. The subject of their analysis was the theoretical, methodological and contextual aspects of literary multilingualism within the framework of the concept of a “supra-regional sphere of literary interaction”. They were regarded through the prism of small, immigrant, transcultural literatures and literature of national minorities. Among them are the Slovenian minority in Austrian Carinthia and Italy, the Italian minority in Croa- tian and Slovenian Istria, as well as the literature of multilingual authors and immigrant authors in Austria and Slovenia, both in modern times, in the 19th century, and during the First World War.
Towards the History of Borrowings in the Russian Language of the Petrine Era: the lexeme Dervish
Authors:   Lomonosov Moscow State University, Pentkovskaya Tatiana
Published: December 2022

The focus of this paper is the rendering of the word deruis in two translations of the Petrine era. Both of them are associated with the name of P.A. Tolstoy, a diplomat who was in the Ottoman Empire in 1702–1714. “The History of the Ottoman Empire Administration”, which was translated from the Italian version of P. Rycaut’s work, has the variant dervish (dervizh). At the same time, in the printed edition of the Quran of 1716, translated from André Du Ryer’s French original, there is a variant drevis, not taken into account in the dictionary of the Russian language of the 18th century. Possible reasons for this discrepancy are considered.

Published: December 2022

The article under consideration dwells on morphological and semantical peculiarities and level of usage of suffix -гоҳ/-goh in “Tarjumai Ta᾿rikhi Yamini” by Jurfodiqoni. The author of the article makes an endeavor to carry out some distinctive morphological peculiarities and to determine the level of usage of the relevant suffix in terms of its tructure and meanings. As a rule, the relevant suffix contributes into the formation of new nouns denoting the notions of place and time from various parts of speech. Adducing the result of an analysis beset with the theme explored one can come to the conclusion that the suffix -гоҳ/-goh is considered to be one of the most productive ones and some words derived by the relevant suffix are not found in MTLL, upon the whole.

Published: December 2022

Based on Marx’s labor theory of value, this paper explains the connotation of the new era of the theory of “two mountains” and its value to the assets of natural resources. The present path carries on the theoretical analysis, uses the case analysis method, the qualitative research method, analyzes the path to realize the value of natural resource assets and the problems faced in the operation process of the “forest ecological bank” operation mode, probes into the natural resources asset value sustainable realization path. The results show that the operation mode of “forest ecological bank” is based on ecological resources, through accurate investigation, on the premise of defining the property rights of ecological resources, using economic methods to calculate its value, directly or indirectly using ownership transactions, ecological service transactions, industrialization and other ways to monetize ecological products. Therefore, we should establish the property right system of market-oriented ecological factors, introduce the main body of market management to develop ecological industry, and establish a “public-private partnership” ecological product trading system, so as to promote the sustainable realization of the value of natural resources assets.

Authors: Ferreira de Carvalho Agnaldo Donizette , Olegário da Silva Giovani , Borges Pereira Ricardo
Published: December 2022

The market demand for uniformity and productivity of commercial carrot roots has prioritized hybrid materials over open-pollinated varieties. In this sense, the objective of this work was to estimate the combining ability of carrot genitors for root productivity and resistance to leaf scorch. The experiments were conducted in Gama, DF, in the agricultural years 2012/13 and 2013/14. We evaluated 33 carrot hybrids, originated from crosses between three male-sterile populations, with 11 male-fertile S2 lines, all the genitors being of tropical origin. At 90 days after sowing, the severity of the leaf blight disease was estimated in the plots. At 100 days after sowing, harvesting was performed and root yield characters were evaluated. Analysis of variance and partial diallel analysis were performed for each year and jointly for both years. It was found that additive and non-additive genes are important in the manifestation of root yield and leaf blight resistance traits in carrot hybrids. The male-sterile parents with higher overall combining ability for root productivity are strains LM-649 and LM-650 and, among the male-fertile, strain LM-555-2-2. The best hybrids for root yield and leaf blight resistance are LM-649 × LM-555-11-1, LM-650 × LM-555-7-1 and LM-650 × LM-554-8-1.

Published: December 2022

The study evaluated the aseptic establishment of Monstera acuminata Koch and Monstera deliciosa Liebm (Araceae) from leaves and the induction of in vitro organogenesis of M. acuminata K. from stem discs of young shoots. For this purpose, different disinfection protocols were applied to mature leaves and young shoots, from which leaf explants of approximately 1 cm2 and stem discs of approximately 1 mm thickness were extracted. The explants were established in semi-solid media with different hormone treatments during the aseptic establishment stage and induction of organogenesis. Disinfection with 3% sodium hypochlorite (NaClO) for 20 min and 50% Murashige and Skoog[1] medium with plant tissue culture preservative (PPM) favored less oxidation in leaf explants of both species. All explants of M. deliciosa in both treatments grown in PPM-added medium and at different disinfection protocols survived, showed no contamination and more than 80% retained cellular activity up to 49 days of culture age. At 35 days of culture, with disinfection in Tween-20 + 20% ethanol + 2.5% NaClO, and seeding of explants in MS medium added with 1 mg/L of BAP, 0.5 mg/L of AIA and 0.1 mg/L of ANA, seven new shoots of stem discs were induced. Monstera deliciosa was more adaptable to in vitro conditions. Advances in aseptic establishment and induction of organogenesis in native Araceae for wicker production are the basis for ex situ conservation of local populations.

Published: December 2022

Sustainable agriculture of forest plantations requires the permanent estimation of the amount or volume of wood being produced at any given time, which is difficult in large forest areas if only manual procedures are used in the field. In the present research, multilayer perceptron artificial neural networks (ANNs) were modeled for the spatial estimation of wood volumes in a Eucalyptus sp. plantation located in the state of Mato Grosso do Sul, Central-West region of Brazil. For this purpose, spectral bands, band textures obtained with gray level cooccurrence matrix and vegetation index, which were derived from SPOT 6 digital satellite image, were used as prediction variables. The resulting ANN with the best performance presented an accuracy of 93.32% and a coefficient of determination of 0.9761, with respect to values obtained with field measurements; however, it presented a relative mean square error of 16.32% (RMSE of 7.85 m3/hm2), but the distribution of residuals was not biased, therefore, the model was promising for mapping timber volumes in large areas without overestimating or underestimating the prediction. The constructed network showed greater precision and accuracy when compared to other methods using similar estimation variables, including when compared to neural models using only spectral bands and vegetation indices.

Published: December 2022

Durante el periodo de confinamiento derivado del virus COVID-19 fueron inevitables la distancia, el aislamiento e incertidumbre entre la población. Los jóvenes universitarios debieron enfrentar emociones como la culpa, por no acudir a las sesiones a distancia; la desconfianza, por la calidad de las clases; el miedo, por percibir que no aprendían y podían reprobar la asignatura; así como la muerte, ante la pérdida y enfermedad de familiares y amigos. Estos son los resultados obtenidos en un estudio exploratorio de corte cuantitativo sobre las acciones y decisiones de los individuos en contextos emocionales realizado en 5 programas académicos, a partir de una encuesta a 455 estudiantes, aplicada en la última semana de actividades escolares, en la Universidad Autónoma de Ciudad Juárez en Nuevo Casas Grandes. Por ello, se afirma que las situaciones límite que se viven al interior de la comunidad universitaria alcanzan el proceso de resiliencia en tanto se hagan conscientes las problemáticas y se enfrenten las dificultades; ello debe ayudar a que se implementen estrategias de aprendizaje mejor articuladas entre profesores, autoridades académicas y estudiantes, a fin de continuar con procesos educativos más amigables; con menor tensión entre los sujetos y de mayor provecho para todos.

Las redes sociales han logrado que su uso llegue a considerarse como esencial en cualquier ámbito de la vida. También en el ámbito educativo, en el cual hacen que el proceso de enseñanza-aprendizaje rompa con los cánones tradicionalistas, promoviendo la eficacia y calidad de la educación. El presente estudio tiene como objetivo explorar cuáles son las redes más utilizadas por el alumnado universitario y con qué fines educativos. Para ello se ha utilizado un método cuantitativo, siendo el cuestionario, diseñado “ad hoc” el instrumento de recogida de información. La muestra la componen un total de 76 estudiantes de la Facultad de Educación de Badajoz. Los resultados indican que las redes sociales están en plena expansión dentro de las aulas universitarias y que WhatsApp es la más utilizada, seguida de Instagram. El alumnado utiliza estas redes de modo educativo para compartir información y/o documentos, apoyarse, mostrar su opinión y participar en grupos (principalmente sin docente). Como conclusión, destacar que las redes sociales son un recurso entre los universitarios y su utilización dentro de las aulas puede ser un recurso muy adecuado dada la cotidianeidad de uso entre las nuevas generaciones.

OBJECTIVE

To evaluate the anesthetic and cardiopulmonary effects of ketamine–dexmedetomidine combined with local anesthesia, associated or not in the postoperative period with different doses of atipamezole, for orchiectomy in cats.

ANIMALS

24 healthy cats.

PROCEDURES

Cats received ketamine (7 mg/kg) combined with dexmedetomidine (10 µg/kg) IM, and 1 mL of saline (group KDSAL), 25 µg/kg (group KDAT25), or 50 µg/kg (group KDAT50) of atipamezole IV, postoperatively. All cats received local anesthesia (2 mg/kg of lidocaine) intratesticular and SC. Physiologic variables were recorded at baseline and at time points during anesthesia. Ketamine rescue dose (1 mg/kg) was recorded. The quality of recovery, the degree of sedation, and side effects were evaluated postoperatively.

RESULTS

2 cats received a single additional bolus of ketamine to perform local anesthesia. Heart rate was lower in KDSAL, KDAT25, and KDAT50 during anesthesia, compared with baseline. Hypertension was observed intraoperatively in all groups. The time to head up, pedal reflex regained time, time to sternal recumbency, and time to standing were shorter in KDAT25 and KDAT50 compared to KDSAL. Lower sedation scores were assigned sooner to KDAT25 and KDAT50 than KDSAL. All groups resulted in low recovery quality scores and no side effects.

CLINICAL RELEVANCE

At the doses used, ketamine–dexmedetomidine combined with local anesthesia allowed the performance of orchiectomy. Rescue dose of ketamine for performing local anesthesia may be required. This combination can result in hypertension. Both atipamezole doses shortened the anesthetic recovery, without differences among them, and side effects.

Published: December 2022

Antioxidants are compounds that inhibit combustion (oxidation) processes. Antioxidants are vital components of our body, which can be obtained in part through plant nutrition. Therefore, it is very important to study species that have significantly higher antioxidant capacity than other species. The aim of the study was to investigate the antioxidant capacity of total polyphenols (TPC) of European mistletoe (Viscum album L.) leafy shoots collected from different species of trees (black locust, European ash, white poplar, field maple and black walnut) based on different methods; DPPH (2,2-diphenyl-1-picrylhydrazyl), FRAP (ferric reducing antioxidant power) and TPC (total phenolic contents). The results proved that the antioxidant effect of leafy shoots from European ash (Fraxinus excelsior) against hydroxyl radicals (ROS) showed significantly higher values than those of the other four tree species. We found that the DPPH, FRAP and TPC methods show significant differences in antioxidant effect of European white mistletoe leafy shoots on the studied tree species and tea brands. However, the FRAP method shows higher sensitivity for trees but for tea brands, the DPPH method is more sensitive. The reason for the difference might be explained by the different methods of drying. In the future, we consider it feasible to plant ash groves at an altitude of at least 80 m above sea level in a closed area, where we can start growing European white mistletoe as an herb. Based on the results obtained European white mistletoe can be recommended as an herb to natural medicine for supplementary treatment of several cancer diseases.

Background: The risk for worse outcomes of COVID-19 (Coronavirus 2019 disease) is higher in patients with cardiac conditions. In this study, we aim to investigate the risks of COVID-19-induced conditions in cases with underlying heart failure.

Methods: We systematically searched PubMed, Scopus, Ovid, ProQuest, Web of Science, and the Cochrane library, to collect the English language articles that investigated patients with underlying heart failure who get infected by COVID-19. The second version of comprehensive meta-analysis (CMA.2) software was used to conduct the meta-analysis.

Results: From 5997 publications, our eligibility criteria were met by 27 studies. Overall, outcomes investigated in all studies include but are not limited to mortality rate, length of hospitalization, need for Intensive care unit (ICU) admission, need for mechanical ventilation, and major cardiovascular conditions. Regarding mortality heart failure patients were more susceptible to death (OR:2.570, 95%CI: 2.085 to 3.169; p-value:<0.001). Also in heart failure patients, the risk of mechanical ventilation was higher (OR:1.707, 95%CI: 1.113 to 2.617; p-value: 0.014).

Conclusion: Pre-existing heart failure is associated with the increased risk of mortality and the need for mechanical ventilation while getting infected with COVID-19. Finding an answer to determine the risk of hospitalization, length of stay, readmission rate, and multiorgan failure is necessary for further development of preventive care and making a plan for providing optimal healthcare facilities for these patients.
Probability Calculation of Upcoming Waves of COVID-19 in Poland

Published: December 2022

We present the problem of risk estimation/assessment of the new coronavirus (COVID-19) spread in Poland. In the literature, a method is given to explain the COVID-19 disease and try to predict the occurrence of the next wave of COVID-19. A Gaussian composite model is used in literature to identify COVID-19 disease. In this model, however, the prediction of the upcoming waves is dependent primarily on the set of selected samples. For different sets of samples, distinct timings of the upcoming waves are obtained. In this article, we assume that probability is associated with each set of samples, which are used for the prediction of the upcoming waves. By exploring this aspect, it is shown that a better prediction of the upcoming COVID-19 waves can be performed.
