Probabilistic characteristics of the water body ice regimes significantly expands knowledge about their variability, magnitudes and appearance timing of main phases. Such knowledge is important for the design and operation of hydraulic structures. Along with this, the probabilistic characteristics of the river ice regimes of Ukraine were calculated in the 70s of the 20th century, including for some rivers of the Pripyat basin. Therefore, the main objective of this research is to determine the probabilistic characteristics and statistical parameters of the appearance dates of main phases of river ice regimes, namely appearance date of ice, date of freeze-up, break-up date (i.e., melt onset), date of ice disappearance in the Prypiat River basin within Ukraine, as well as the analysis of the obtained results. The research was carried out based on the data of 29 water gauges for the period from the beginning of observations to 2020. Such indicators as the multi-annual mean, standard deviation and asymmetry coefficient were used as statistical parameters. The analytical distribution of the appearance dates of main phases of river ice regimes is determined by the Pearson curve of type III, and empirical distribution is determined by the Weibull formula. Statistical series of the appearance dates of main phases of river ice regimes were arranged from early to late dates, namely low probability values were assigned to early dates, and large probability values were assigned to later dates. Pearson probability distribution of type III quite successfully describes the empirical points of main phases of river ice regimes of the Pripyat basin within of Ukraine. Analytical distribution curves have a slight negative asymmetry for the dates of the ice appearance and freeze-up, and a positive asymmetry for the dates of the break-up and ice disappearance. The variability of standard deviation and multi-annual mean of the appearance dates of main phases of river ice regimes is within ±7.5-10 days and 3-4 weeks, respectively. In general, the appearance dates of main phases of river ice regimes, as well as their statistical parameters and probabilistic characteristics have close values that are subject to geographic zoning. The analysis of changes over time in probabilistic characteristics and statistical parameters of the dates of ice appearance and freeze-up showed that the greatest changes have by probabilities that are not repeated often, and the smallest – by multi-annual mean and asymmetry coefficients.

Authors: Gromova O. A. , Torshin I. Yu. , Gromov A. N.
Published: November 2023

Background. The enzymatic cofactor coenzyme Q10 (CoQ10) is involved in the synthesis of adenosine triphosphate in mitochondria. The CoQ10 biosynthesis declines when using statin drugs.

Objective: systematization of the impact of coenzyme Q10 on chronic, sluggish systemic inflammation leading to the development of atherosclerosis, liver and pancreas pathologies, and neurodegeneration.

Material and methods. Systematic computer analysis of 16,788 publications on CoQ10 found by the query “coenzyme Q10 OR ubiquinone” in PubMed/MEDLINE database of biomedical publications was carried out. Current methods of topological and metric data analysis developed at the scientific school of Academician of the Russian Academy of Sciences Yu.I. Zhuravlev were used.

Results. CoQ10 is involved in the regulation of inflammation and exhibits lipid-lowering, hepatoprotective, nephroprotective, anti-asthenic, cardioprotective, and neuroprotective effects. CoQ10 favorably affects carbohydrate metabolism and a wide range of neurological diseases.

Conclusion. CoQ10 supplementation improves glycemic control in insulin resistance, kidney function, and is useful in the treatment of migraine and neurodegenerative pathologies (Parkinson’s disease, etc.).

Published: November 2023

Objective: assessment of feasibility of using four-component drug therapy for patients with chronic heart failure with reduced ejection fraction (CHFrEF) in medical organizations of the Moscow Region (MR).

Material and methods. Clinical and economic analysis of combined standard therapy with angiotensin-converting enzyme inhibitors, beta-blockers, and mineralocorticoid-receptor antagonists in combination with dapagliflozin (a sodium-glucose cotransporter 2) in the treatment of patients with CHFrEF was carried out. The effectiveness criteria were the number of prevented cardiovascular (CV) deaths and the percentage of the contribution to the achievement of the target indicator to reduce mortality from circulatory diseases within the framework of the regional program “Health care development”. In order to determine the economic feasibility of quadritherapy, direct medical costs for the implemented technology were calculated, the cost of one prevented CV death was determined based on the values of the number needed to treat (NNT) indicator. Budget impact analysis was performed which allowed to build two analytical models.

Results. It was shown that the use of quadritherapy can significantly contribute to achieving the target indicator by additionally preventing 512 CV deaths by 2024, which will make it possible to fulfill up to 74.74% of the indicator set by the MR state program “Health care of the Moscow Region” (451.4 persons per 100 thousand population). Using quadruple therapy in 1000 target patients during the first year will prevent 11 CV deaths (NNT 90 persons). The cost of one prevented CV death was 3.860 million rubles. The budget impact analysis made it possible to determine that when CHF patients switch from standard treatment regimens to quadritherapy, including in combination with a drug of the angiotensin/neprilysin receptor inhibitor group (valsartan + sacubitril), this will entail an increase in healthcare system budget costs by 18.8%.

Conclusion. The results demonstrate that the standard therapy in combination with the innovative drug dapagliflozin leads to a proven reduction in mortality from circulatory diseases. This technology is a cost-effective approach to organizing medical care for adult patients with CHFrEF on the MR territory.

Published: November 2023

Objective: The objective of this study was to analyze the effect of night shift work on nurses’ health and well-being. Methods: 100 nurses in all were chosen at random from various hospital located in Itanagar. Data was collected from night shift working nurses by self-administered questionnaire through personal interview method. Data was used to gather information on socio- demographic, anthropometric measurements, professional, physical activity, food habits and intakes were collected. To study the detrimental impact of night shift employment on the health and wellbeing descriptive frequency and correlation were used. Results: One hundred nurses in all, the majority of them had one or more health issues, digestive problems includes- disturbed appetite (60%), heartburn or stomach-ache (71%), feeling nausea/ dizziness (75%), difficulty in digestion (72%) and suffer from constipation (52%). Cardiovascular problems of the respondents it was found that out of 100 respondents (16%) workers reported that they are on their high blood pressure or cardiac problems and chronic chest disorder (6%) followed by (45%) workers were low blood pressure. About 23% of nurses regularly skip meals, followed by 52% of nurses who did so once or twice, and the majority of nurses did not eat at set times. The results showed that 72% of nurses often ate fast food; only 8% of nurses took home-cooked meals with them for dinner. During night shifts, chips, cookies, sweets, and were the most popular munchies. Conclusion: This study demonstrated that nurses working nights have bad eating habits that cause their diets to be unbalanced. They eat less nutrient-dense foods but a greater number of meals that are rich in calories. They also rarely engage in any sort of exercise outdoors from what they do for a living and frequently prefer to eat snacks rather than full meals. The hospital's nurses need to get nutritional hygiene counseling, and night shift food service needs to be enhanced.

Published: November 2023

A field experiment on line × tester mating method for analysis was conducted in 2021 at the Plant Breeding Farm, Department of Genetics and Plant Breeding, Annamalai University, Annamalainagar, Tamilnadu. The experiment involved the evaluation of eight lines, five testers, and their resulting 40 crosses of bhendi (okra) for the study of gene action and heterosis. The data was observed for eleven yield and yield contributing traits. The present study indicated the preponderance of non-additive gene action for days to 50 percent flowering, plant height at maturity, number of branches per plant, fruit length, fruit girth, internodal length, number of fruits per plant, average fruit weight, number of seeds per fruit, 100 seed weight and fruit yield per plant. Only dominant component of variance was observed which revealed the presence of non-additive gene action hence, heterosis breeding is required to be followed for exploitation of these traits. The investigation of heterosis may provide valuable insights for the selection of heterosis crosses suitable for the commercial cultivation of F1 hybrid okra. Based on the experiment results, the crosses IC 104 × Arka Anamika, IC 107 × Arka Anamika, IC 3052 × Arka Abhay, and IC 3025 × Arka Abhay displayed excellent performance in terms of heterosis. Therefore, these crosses are worthy of consideration for future breeding development programmed.

Influenza A and B viruses are widely spread respiratory pathogens of humans and cause both isolated cases and local outbreaks of the disease, as well as massive seasonal epidemics and pandemics. Vaccination is the main strategy for combating influenza, and an increase in the proportion of vaccinated people in the population determines the success of vaccination. To identify patterns of postvaccination immune response formation to different types of vaccines and assess the significance of its multiple parameters the appropriate statistical methods should by applied. These methods allow to operate with large datasets and reduce their dimension, while keeping the maximum of information about the differences between individual observations. The aim of our study was the analysis of parameters of humoral and cellular immunity and their dynamics after vaccination with different types of inactivated influenza vaccines (IIV) using statistical methods of complex data analysis. The study was conducted in the clinical department of the Smorodintsev Research Institute of Influenza, Ministry of Health of the Russian Federation, in the flu season 2018 – 2019. The multivariate analysis of the immune response parameters after immunization with IIV “Grippol plus”, “Sovigripp” “Ultrix” included data obtained for 39 volunteers before vaccination, on the 7th and 21st days after vaccination. To identify parameters with significant differences between groups, one-factor analysis of variance (ANOVA) was used separately for each parameter and time point. To visualize the differences in the parameters selected in the analysis of variance, the Principal component analysis (PCA) method was used. The conducted studies revealed the peculiarities of the formation of a post-vaccination immune response to various types of IIV. It was shown that the factors of antigen-specific CD4+ and CD8+ T-cell immune response introduced the major contribution to the formation of the differences between groups. The approach is a powerful tool in analyzing the parameters of the immune response in clinical trials of influenza vaccines and other preventive medicine.

BACKGROUND: Associations between genetic stability of human somatic cells and solar activity across latitudes have been studied. A human buccal epithelium micronucleus test was selected as a method for evaluating genetic homeostasis.
AIM: To assess effects of solar activity on the genetic stability of human somatic cells using the micronucleus test in buccal epithelium in relation to the geographical location of subjects.
METHODS: Men aged 18 to 21 years with no harmful habits and taking no medication comprised the sample. Studies were conducted simultaneously in four cities of the Russian Federation: Sevastopol, Voronezh, Tomsk, and Khanty-Mansiysk. The effect of three types of solar flares, whose classification is based on changes in the amplitude of the thermal X-ray burst, was studied. Material for the cytogenetic study was collected on days 3, 7, and 10 after the solar flare. The human buccal epithelium micronucleus test was selected as a method to evaluate genetic homeostasis. At least 1,000 cells were examined on each preparation, among which the number of cells with micronuclei, perinuclear vacuoles, notches, “broken egg” and “tongue” type protrusions, karyorexis, karyolisis, and karyopyknosis was determined. In total, 495 thousand buccal epithelial cells were analyzed. Statistical processing of the data was performed using “Stadia” and “Statistica” software packages. Effecs of solar andlatitude on genetic homeostasis of somatic cells was performed using multivariate analysis of variance and two-factor analysis of variance with fixed effects.
RESULTS: Solar activity affected the stability of the human genetic apparatus by increasing the influence of the city pollution and its geographical location on the number of cells with nucleus abnormalities. We also observed a combined effect of solar flare and season on the number of cells with nucleus aberrations. More nuclear anomalies were registered in the winter. We did not detect any difference in the number of cells with nucleus anomalies on the 3rd, the 7th, the 10th, and the 17th days after the flare suggesting no associations between solar activity and the number of cells with nuclear abnormalities.
CONCLUSION: The highest number of cells with nucleus abnormalities is observed in Sevastopol reflecting with the greatest level of anthropogenic pollution of this city compared to the other locations. Solar activity increases the influence of the city pollution and its geographical location on the number of cells with nucleus abnormalities. The results obtained can be used in conducting a micronucleus test of human buccal epithelium and in planning measures to assess the genotoxicity of the environment.

Authors: Reyes-Tagle Gerardo , Dimitropoulou Christina , Rodríguez Peña Cristian Camilo
Published: November 2023

Technological advances offer enormous and still unexploited opportunities to the tax administrations of Latin America and the Caribbean to improve their tax services. This report assesses current digitalization levels in tax administrations across the region, describes the legal framework necessary for digitalization, and identifies areas for improvement based on good tax administration principles and best practices. It offers roadmaps for improving digital taxpayer services that consider important differences across more and less digitally advanced countries. In all countries, progress on the digitalization of tax services can lead to better tax compliance and governance. However, less advanced countries should focus first on facilitating taxpayer connectivity and the digitalization of tax documents; more advanced countries should implement automated tax filing and data-sharing among government agencies.

La Santissima Trinità è “democratica”? La dottrina di Dio e le dottrine socio-politiche
Authors: Kowalczyk Dariusz
Published: November 2023

L’autentica fede in Dio, rivelatoci in Gesù Cristo, è una fede incarnata che, in qualche modo, unisce le cose dell’al dì là con le esperienze di questo mondo. La teologia politica ha come obiettivo di riflettere sul come la riflessione teologica può o dovrebbe influire sulla vita socio-politica. Il monoteismo teologico è stato usato, nel passato, per giustificare e rafforzare il potere degli imperatori. Tali tentativi hanno purtroppo portato, a volte, ad abusare della dottrina cristiana a favore della politica. Una possibilità per correggere la prospettiva della teologia politica è stata ricavata dalla teologia trinitaria, cioè dalla verità che in Dio l’unità va sempre insieme alla diversità.  Dio non è solo uno ma è anche trino, cioè costituisce una comunità di uguaglianza e alterità. Possiamo, allora, individuare uno stile trinitario che potrebbe essere applicabile anche alle dottrine socio-politiche moderne. Si deve, però, ricordare che come ci sono state delle indubbie esagerazioni nel voler giustificare teologicamente le monarchie, esse ci possono essere anche nell’individuare ed indicare delle analogie tra la dottrina trinitaria e i sistemi democratici. La Chiesa, per vocazione impegnata socialmente, è chiamata – sulla via dell’Apocalisse – a mantenere la dimensione profetica ed escatologica, mentre testimonia ed annuncia che Deus semper maior, cioè essa fa memoria e ricorda agli uomini di ogni tempo che a qualsiasi somiglianza tra Dio e il creato corrisponde sempre una più grande dissomiglianza.
Developing an Attitude of Positive Tolerance Among Young People in Poland a Collective Case Study
Authors: Zelma Anna
Published: November 2023

This paper presents the findings of a quality study conducted in 2021 on developing an attitude of positive tolerance among young people in Poland. The collective case study method was applied. Five cases of educational institutions were analysed whose statutes provide for the promotion of the pedagogy of tolerance inspired by the teachings of John Paul II. The research sample comprised: The Centre for the Thought of John Paul II, the “Opus of New Millenium” Foundation, the John Paul II Institute for Intercultural Dialogue in Kraków, the St. John Paul II Youth Aid Foundation “Wzrastanie,” and the Association of Friends of Catholic Schools. The educational programmes of these institutions mainly address young people in Poland. The study revealed that positive tolerance, based on an axiological foundation, occupies an important position in the activities of these institutions. Founded on the teachings of John Paul II, it incorporates human dignity, respect, the common good, responsibility, intercultural and inter-religious dialogue, and cooperation. The study revealed that educational initiatives were diversified concerning the content and methodological solutions, whose aim is to discover the essence of positive tolerance and its boundaries. These create various opportunities to get to know another person, show respect, dialogue, change prejudices, cooperate, and build unity in diversity. Young people are encouraged to engage in intercultural and interreligious dialogue both directly and using the latest information and communication technologies that favoured the development of a positive tolerance attitude.
A Reflection on the Impact and Connection of AI with Humanities
Authors: Kabali Samartoiy Farhad , Davar Mohamad Mahdi
Published: November 2023

Artificial intelligence, as a phenomenon that has a wide scope in various issues and topics, is also related to humanities and plays an effective role in it. The two basic questions of this article are whether artificial intelligence is related to humanities and whether artificial intelligence has an effective role in humanities. By reflecting on each of the questions, we can see that AI is related to humanities and plays a role in it. Its relevance is due to the fact that humanities have the potential to be related to other fields, and of course artificial intelligence will also have this capability. Regarding the second question, it should be said that AI can play a role in humanities in three ways. 1. Have an active role; 2. Help humanities researchers; 3. Be raised as a subject to be investigated in humanities.

The extract was deprived of chlorophyll by solid-phase extraction, using Diaion Hp-20 resin as solid phase, and eluting with a mixture of EtOH/H2O according to a decreasing polarity gradient. The chlorophyll-free extract was then repeatedly fractionated by open column chromatography in normal phase and preparative thin layer chromatography. Two main metabolites were finally purified and identified through structure elucidation. Nuclear magnetic resonance spectroscopy (NMR) and electrospray ionization-mass spectrometry (ESI-MS) were the 2 techniques used for analysis. The identified metabolites were coumarins: (1) umbelliferone and (2) coumarin-5- methyl-4α-glucoside. Compound 1 is known in the literature for having anti-inflammatory, antihyperglycemic, and antitumor activities. Compound 2 has not been described before for this botanical genus and its pharmacological effects are still uninvestigated.

The red rose is one of the perspective natural resources of anthocyanins, however kinetic study for anthocyanins extraction of red rose petals is not yet elucidated. Red rose petals were dried at 303 K and ground (particle size ~ 5 mm). The petals were extracted by aqueous acid solutions using conventional solid-liquid extraction. The efficiency of 0.1 M aqueous solutions of acids as extractants towards red rose anthocyanins was studied and it can be arranged in the following row: citric acid < acetic acid < hydrochloric acid. Kinetic investigations focusing on the temperature effect on solid-liquid extraction of anthocyanins from petals of red rose were performed at three temperatures (293, 313, and 333 K). Kinetic curves were obtained using an aqueous solution of hydrochloric acid. It was found that the rate of extraction of anthocyanins was very fast at the beginning, but it began to slow down after 60 minutes for all temperatures. The experimental kinetic curves of the extraction of anthocyanins at different temperatures were obtained and analyzed using common empirical kinetic models (the first-order, second-order kinetic models, the Peleg model, and the power-law model). The second-order kinetic model provided the best agreement with the experimental results in terms of statistical parameters (coefficient of determination (R2) and average relative error (ARE)) than other studied models. As temperature increases, the second-order rate constant values and the initial extraction rate values also increased. The second-order rate constants were used to evaluate the activation energy of extraction. The calculated activation energy of the anthocyanin extraction is 39.3 kJ/mol, which is an indication of an endothermic process. Obtained data can be used to predict the extraction of anthocyanins from red rose petals.

Natural flocculants as chitosan and sodium alginate has a complex of environmental and physic-chemical properties: biodegradability, playback of the raw material base, reaction and complexing ability. Researches had shown that natural polymers can be used for flocculation of suspensions. Association has a specific role in the flocculation process.
Association determined by the nature and charge density of the flocculants. It is necessary to understand the mechanism of processes in these systems in order to select an effective flocculants. The mechanism of action of compositions natural flocculants is different from synthetic. The state of biopolymers depends on the pH of the solution. The aim of our researches was to study the flocculation ability of the compositions natural flocculants.
It was studied sedimentation stability of suspensions containing macromolecular substances (flocculants) of different nature. We used an aqueous suspension of kaolin and bentonite. Kaolin and bentonite were dried to constant weight. The concentration of the dispersed phase in suspensions was 1–3%. It was shown that the sedimentation stability defines as flocculants characteristics such as molecular weight, concentration, nature of flocculants, polyelectrolyte’s charge density and nature of the suspensions. It was found that compositions of natural flocculants chitosan and sodium alginate are more effective of individual flocculants. The degree of separation suspensions reaches 90–98%. The findings suggest that the studied natural flocculants have significant potential for use, thanks to a number of advantages: the efficiency of their actions, low reagent consumption, environmental safety.

Abstract: Online learning provides more opportunities and flexibility in constructing knowledge and acquire skills. However, it also creates transactional distance. Students become more anxious and feel pressured. The distance makes the learning process does not meet student needs and interests. Learning interaction offers a key to minimize the distance and ensuring learning satisfaction. Satisfaction indicates the meaningful activities in the learning process. This research aims to investigate the effect of balanced interaction between humans and learning content on student satisfaction. A Quasi-experimental posttest-only group design was used. The experimental group was taught using an online flipped classroom with balanced interaction, and the control group was taught using a traditional online classroom. Two intact classes that consist of 44 students were used. This research found out that level of student satisfaction in both groups were at a moderate level. Although statistically not significant, the mean differences showed that students in the control group felt more satisfied than students in the experimental group. Keywords: Flipped Classroom, Interaction, Online Learning, Satisfaction. Abstrak: Pembelajaran daring memberikan lebih banyak kesempatan dan fleksibilitas dalam membangun pengetahuan dan memperoleh keterampilan.

La Nueva Argentina: uma história que Dona Benta não contou
Authors: Rocha Michele Saionara Aparecida Lopes de Lima
Published: November 2023

Após grande sucesso no Brasil, Monteiro Lobato expandiu suas projeções publicando diversas traduções de suas obras na Argentina, que, posteriormente, foram também difundidas em outros países da América Latina. O êxito literário fora de seu país colaborou para que o autor almejasse a produção de textos inéditos em língua espanhola e, entre seus intentos, em 1947 a obra infantil La nueva Argentina foi publicada pela Editoral Acteon sob o pseudônimo de Miguel P. Garcia, contando com uma tiragem de 3.000 exemplares impressos. A história, que não teve a participação dos personagens consagrados do Sítio do Pica-pau Amarelo, foi protagonizada por don Justo e seus filhos Pancho e Pablo Saavedra e apresentou como tema central reflexões sobre o Plano Quinquenal implementado na Argentina pelo general Juan Domingo Perón. Diante desse tema, o trabalho que aqui se apresenta tem o objetivo de analisar La Nueva Argentina destacando quais foram os principais ideários do peronismo que Lobato contemplou em sua escrita. O estudo foi produzido a partir da abordagem qualitativa e por meio de pesquisa bibliográfica e documental. Como resultado, é possível indicar que em La nueva Argentina Lobato teceu importantes apontamentos sobre como os aspectos sociais, econômicos, educacionais, culturais, de saúde pública, de diplomacia, de defesa nacional, de obras públicas e de transportes poderiam ser pensados a partir dos preceitos do movimento político de maneira a promover ações voltadas para a justiça social entre a população do país.
Escrita, leitura e experimentação nos Ciclos de Oficinas
Authors: Nascimento Rafael Caetano do , Joaquim Felipe Ferreira
Published: November 2023

O texto a seguir apresenta o Ciclo de Oficinas, que foi, durante o período crítico da pandemia de Covid-19, uma iniciativa extensionista desenvolvida pela Universidade Federal do Tocantins (UFT) e coordenada pelos autores, então professores substitutos da citada instituição. O Ciclo de Oficinas caracteriza-se como uma proposta de experimentação pela leitura e pela escrita, por meio de encontros virtuais em tempo real em que os participantes são convidados a produzir escritas e a compartilhá-las, tendo como dispositivos objetos diversos de linguagens variadas. Enquanto estratégia de composição textual, e considerando a cartografia e a pesquisa-experimentação horizontes teórico-metodológicos, optamos por descrever o nosso itinerário formativo ressaltando a opção pela oficina como formato conveniente para práticas educativas de cunho experimental e o modo como as práticas de leitura e escrita contribuíram para a construção dessa jornada até se tornarem o objetivo fundamental de nosso interesse como educadores e pesquisadores. Finalizamos com uma cartografia das oito edições do Ciclo de Oficinas realizadas pela UFT, traçando alguns elementos reflexivos, em consonância com as falas e as escritas registradas pelos participantes, que argumentam em favor da experimentação como mote educativo, tendo a leitura e a escrita como práticas inventivas de si, do outro e de mundos.
