Authors:   Ivan Franko National University of Lviv, Polishchuk K. , Olishevska V. ,   Ivan Franko National University of Lviv
Published: June 2022

The importance of sport and sports entities as active factors of the international agenda formation is proven in this article. The arguments for replacing the classic actors of the world arena with non-standard units, such as individual athletes and sports teams and organizations are given in this context. While emphasizing the fact that they are becoming mouthpieces and lobbyists for specific demands of society more and more often, the analysis of such a phenomenon of politicization and socialization of actors as well as the actors’ tools in such activities as symbols, narratives and physical space is carried out as well. The main research topics of most scholars who focus on the mentioned relationship between politics and sports are nationalism, propaganda, the struggle of ideologies and power through the prism of politics in sport whereas this article also highlights the use of sport as a tool of communication and local identity strengthening. Some of the analyzed sources concern the fixation of events and personalities (Guillem Balague, Dave Zirin, Franklin Foer), while others tackle with philosophical and anthropological issues (Zygmunt Bauman, Erin Tarver, Christopher Gaffney), thanks to which a sufficient level of this phenomena is supplied (especially these are American and British researchers) as well as the need for a multidisciplinary approach to the choice of methodology and areas of analysis is outspoken. The aim of the article is not only to study the sources that shed the light on this issue, but also to give the international (Olympic Games, Mohammed Ali, Marcus Rashford, etc.) and Ukrainian examples (FC «Karpaty») from history and the present. The importance of analyzing fans’ narratives (banners, songs, perception of themselves and others, etc.) and symbolic objects of the urban landscape (stadiums and sports infrastructure in general) is emphasized in order to understand the trends in society that fans and objects represent.

Published: June 2022

Cervical cancer is an important public health problem. The incidence of cervical cancer in the world is 10.6 per 100,000 women. Often in the literature, cervical cancer is called a disease of inequality due to a significant difference in the morbidity and mortality rates between the developed and developing countries. In Russia, the mortality and incidence rates of cervical cancer do not tend to a decrease. High prevalence of human papilloma viral infection, lack of organized screening, an organized cytological registry and quality-controlled cytology can be the reasons of the low success rate in implementation of cervical cancer prevention programs. There is a need of studies of human papilloma virus (HPV) prevalence in Russia, a need of national screening programs, development of laws regulating use of HPV vaccine.

The results of a cross-sectional study of 224 patients, Arkhangelsk residents, with the acute coronary syndrome (ACS) have been presented. Features of the disease course, approaches to treatment and complications in the women with ACS under the age of 55 compared with the men have been analyzed. It has been determined that the women under the age of 55 with ACS both with elevated ST- segment and without ST elevation were admitted to hospitals much later. This was caused by inadequate prehospital assessment of the clinical picture and frequent ACS atypical manifestations. In the hospital period, the women showed greater incidence of complications as bleeding (hematoma after lumbar puncture) and acute decompensated heart failure (ADHF) (pulmonary congestion, pulmonary edema) compared to the men.

The study included 26 hazardous occupations specialists (men aged 20-32 years old), with signs of abnormalities of the psycho-physiological status (PPS) involved in intensive work. In the basic group (BG) (n=14) the specialists were trained with use of hypoxic artificial gas-air environments -HAGAE (O 2 content 15-17 %, duration of each procedure 45 min, the total number of procedures 12). For 12 people (the comparison group - CG), HAGAE conditions were simulated. PPS deviations were evaluated according to the state of the sensorimotor properties, the electroencephalographic (EEG) criteria, the level of reactive anxiety (RA). The studies in both groups were conducted prior to the correction measures (simulation) application, directly after the end of the program and in a month. In all individuals of the BG after the workouts, there was recorded an improvement of the PPS parameters compared to the initial level, such changes were absent in the CG, for which reason, there have been found statistically significant (p < 0.05) intergroup differences in a number of the sensorimotor parameters, the EEG criteria, the RA level. The program based on the use of HAGAE, can be regarded as a method of choice in restoring PPS of hazardous occupations specialists.

Published: June 2022

There were examined 1 656 young male residents of the Magadan region from among aborigines aged 17-21 y. o., migrants and Caucasoid natives of the Magadan region of the 1st 2nd generations in order to study their morphofunctional parameters. It has been found that among the modern population of the male aborigines and the Caucasoid natives residing under similar natural-climatic conditions, there were observed processes of convergence of some of their physiological parameters. Those processes allowed to consider the phenomenon as a certain stage of convergent adaptation. Moreover, the vector of the change indices’ focus among the migrants and different generations of the Caucasoid natives allows to state formation of a new population that is developing in the Northeast of Russia. We specify this new population as a population of rooted residents who have different functional indices as compared to those of aborigines or migrants.

Published: June 2022

We have studied transformation of smooth muscular tissue (SMT) of the uterus wall of rats after delivery and used the light and electronic microscopy and the immunohistochemical method. The study of different parts of the uterus in the process of involution has shown different levels of SMT structure functional reorganization. It can be explained by different speed of the involutive processes and peculiarities of the loading functions. The complete involution of the myometrium of the rats’ horns was reached in 7 days after delivery. The same process in the cervix took more time, and correlated increased small cells population. We found that disappearance of large cells became the main factor of SMT reconstruction in all the parts of the uterus during the period after the delivery, the large cells were characterized by a low level of adaptation to the changing factors. The mechanism of the cells disappearance and reconstruction of the population structure depended on apoptosis and proliferation of smooth muscular cells.

The Role of Transcranial Magnetic Stimulation in Understanding Attention-Related Networks in Single Subjects
Authors:   , Yeager Brooke Eliese , Medaglia John D
Published: June 2022

Attention is a cognitive mechanism that has been studied through several methodological viewpoints, including animal models, MRI in stroke patients, and fMRI in healthy subjects. Activation-based fMRI research has also pointed to specific networks that activate during attention tasks. Most recently, network neuroscience has been used to study the functional connectivity of large-scale networks for attention to reveal how strongly correlated networks are to each other when engaged in specific behaviors. While neuroimaging has revealed important information about the neural correlates of attention, it is crucial to better understand how these processes are organized and executed in the brain in single subjects to guide theories and treatments for attention. Noninvasive brain stimulation is an effective tool to causally manipulate neural activity to detect the causal roles of circuits in behavior. We describe how combining transcranial magnetic stimulation (TMS) with modern precision network analysis in single-subject neuroimaging could test the roles of regions, circuits, and networks in regulating attention as a pathway to improve treatment effect magnitudes and specificity.

Published: June 2022

The melon is of socio-economic importance, especially in the north-east of Brazil. Obtaining homozygous lines has been an obstacle in breeding programs. In vitro androgenesis is one alternative, requiring the development of protocols for anther culture. The aim of this work was to study the effect of auxins and cytokinins on callus induction in anthers of the Goldex hybrid yellow melon. Two experiments were conducted in a completely randomised design, with 25 replications. In the first experiment, in a 3 x 3 factorial scheme, the treatments comprised concentrations of 6-furfurylaminopurine - KIN (0.0, 3.0 and 6.0 mg L-1) and indolylacetic acid - IAA (0.0, 3.0 and 6.0 mg L-1), added to Murashige and Skoog (MS) medium. In the second experiment, six treatments were tested: MS with no growth regulator; MS + 0.20 mg L-1 6-benzylaminopurine (BAP); MS + 0.20 mg L-1 naphthaleneacetic acid (NAA); MS + 0.45 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D); MS + 0.20 mg L-1 BAP + 0.20 mg L-1 NAA; and MS + 0.20 mg L-1 BAP + 0.45 mg L-1 2,4-D. The following were evaluated 60 days after anther inoculation: induction percentage, oxidation intensity, colour, texture, and the area and fresh weight of the callus. The auxins (IAA, NAA and 2,4-D) and cytokinins (KIN and BAP) induce callogenesis in anthers, but only in combination, the most suitable being 0.20 mg L-1 BAP + 0.45 mg L-1 2,4-D. The calli have a beige colour, friable texture and medium oxidation, with a strong association between the fresh weight and the area.
Aplicação de um Minerador de Emoções em Fóruns de Discussão de um Massive Open Online Course (MOOC) Brasileiro: uma Abordagem Utilizando o Algoritmo Naive Bayes
Authors: Souza Vanessa Faria de
Published: June 2022

Em gradativa evolução devido à disseminação dos ambientes virtuais de aprendizagem, os MOOCs disponibilizam aos participantes inúmeros meios de interação. Dentre esses meios, destaca-se o fórum de discussão, ambiente que registra diferentes informações a respeito do engajamento dos alunos. Contudo, realizar a leitura de todas as postagens é uma tarefa difícil, pois os MOOCs costumam ter uma faixa muito alta de alunos matriculados. Nesse sentido, a mineração de textos pode auxiliar professores a obter conhecimentos relevantes sobre as postagens dos alunos. Levando em consideração essas discussões, neste estudo, foi realizada a implementação de um minerador de emoções para fóruns MOOC, utilizando a linguagem de programação Python, com o objetivo de identificar e analisar os sentimentos que cada aluno expressa ao interagir com os colegas nesses ambientes. Os resultados obtidos, em experimentos iniciais, indicam que o minerador mostrou-se eficiente na extração das emoções dos alunos, alcançando uma acurácia de 40%. Além disso, mostraram que sentimentos positivos, como alegria e surpresa, refletem na conclusão dos MOOCs, enquanto sentimentos negativos, como tristeza e raiva, são indicativos de abandono do curso.

Authors: Imbana Rugana , Blum Susana Churka , Aguiar Maria Ivanilda , Sousa Geocleber Gomes de , Ndami Medna , Dabó Ibraim
Published: June 2022

As leguminosas podem ser eficientes para aumentar os teores de carbono (C) e nitrogênio (N) no solo. Com base nisso, objetivou-se com o presente estudo selecionar plantas leguminosas com o maior potencial para acumular C e N no solo. O experimento foi conduzido em 2018, em Redenção, Ceará. O delineamento experimental adotado foi em blocos casualizados, com oito tratamentos e três repetições. Os tratamentos correspondem a: controle (solo sem cobertura vegetal), palha, mucuna preta, mucuna cinza, lablab, feijão-guandu, crotalária e feijão-de-porco. No florescimento (aos 67 dias após a semeadura), as leguminosas foram cortadas e deixadas sobre a área. Aos 78 dias após o corte, amostras de solo foram coletadas nas camadas de 0-5 e 5-10 cm para determinação da densidade do solo (Ds) e de partículas (Dp), porosidade total (Pt), carbono orgânico total (COT), estoques de carbono (EstC) e nitrogênio (EstN), nitrogênio total (NT) e a relação de carbono com nitrogênio (C:N). As plantas de cobertura não alteraram Ds, Dp, Pt, NT e a relação C:N, em razão da textura arenosa do solo e curto período experimental. Porém, contribuíram para o aumento dos teores de COT. As plantas leguminosas são capazes de aumentar o estoque de carbono do solo mesmo em curto prazo. A mucuna cinza é a planta leguminosa com maior potencial para acumular C no solo. No entanto, para manutenção de resíduo orgânico no solo é recomendado o uso de Crotalaria juncea.

Authors: Buquera Rodrigo Brezolin , Marques Paulo Eduardo Moruzzi , Franco Fernando Silveira
Published: June 2022

Apesar do crescimento do mercado de orgânicos no Brasil, estes alimentos permanecem restritos a uma pequena parcela da população. Neste cenário, os circuitos curtos de comercialização se apresentam como uma alternativa ao modelo predominante de distribuição de alimentos, marcado pela impessoalidade e longas distâncias. Este artigo se propõe a analisar as motivações dos consumidores de produtos orgânicos e este mercado em Sorocaba/SP. Para esse propósito, adotou-se dois procedimentos metodológicos: um levantamento on-line, de caráter quantitativo, e entrevistas semiestruturadas, de caráter qualitativo. Como resultados, os hábitos dos consumidores revelam duas posturas distintas: uma valorização da praticidade e uma busca por diversificação, tanto de produtos quanto nas formas de compra. Nestas escolhas, os consumidores alternam entre os circuitos curtos e longos em um formato híbrido, tendo como principais referências para suas compras os supermercados e as feiras.

Published: June 2022

Floodplains were the first deforested areas for agriculture use all over the world. In Brazil these areas can be restored by the growth of guanandi Calophyllum brasiliense, a slow-growing native forest species adapted to flooding. The aims of this study were to: (i) evaluate the taro, Colocasia esculenta, management under two agroforestry systems (AFS) (Simple and Biodiverse) in succession to a reforestation with guanandi, (ii) evaluate the contribution of macronutrients from the green manure Flemingia macrophylla and Sesbania virgata, both managed using pruning for green manure in the respective AFSs, and (iii) the effects on soil nutrients levels compared to monoculture of guanandi (control). The randomized block was designed with eight replication and 216.0 m² plots with four rows of six guanandi trees in each line. In the simple AFS (SAFS), the taro was intercropped with Flemingia and in the biodiverse AFS (BAFS), Sesbania, banana shrub (Musa sp.), edible palm (Euterpe edulis) and fourteen species of native trees were included. Production was evaluated in seasons with high rainfall and water scarcity. With floods the taro has produced around 15 Mg ha-1 of marketable corms in the SAFS and 9 Mg ha-1 in the BAFS, but the drought has made commercial production unfeasible, with no differences between cormels and corms planting. However, enough rhizomes were harvested for a new planting. Flemingia has accumulated 17 Mg ha-1 of fresh matter and Sesbania contributed with 2 Mg ha-1. Soil pH and macronutrient content, especially K, were significantly higher in AFSs areas compared to guanandi monoculture.

В этом бренном мире все процессы имеют свои законы и закономерности. Всѐ можно познать и описать, а то, что нельзя, оставим философам идеалистам. Так и у экономики есть свои объективные материальные законы бытия, или движения – то есть рождения, развития и смерти. Но экономика на современном этапе своего движения не может существовать без денег и системы их движения по экономике. У природы движения денег тоже есть свои законы и закономерности, без которых еѐ бы просто не было.

There is an increasing need for clean water because of the growing population. However, the amount of clean water is decreasing due to poor water resource management. Several textile industry processes result in waste. Color, alkalinity, high TSS, high BOD, and some dyes are known to contain chromium elements and are all common characteristics of liquid waste produced by the textile industry. The goal of this study was to assess the performance of textile waste treatment units in Pringsurat Subdistrict, Magelang Regency, Central Java Province, as part of an effort to reduce river water pollution. Quantitative and qualitative methods were used including through surveys and mapping. Groundwater flow maps, and river water and wastewater levels of BOD, COD, TSS, phenol, chromium, ammonia, and sulfide were used as primary data. Unpleasant odors and discoloration of the river were observed. It is recommended that, to reduce the impact of the wastewater, a constructed wetland with a combination of two types of plants, Iris pseudacorus and Thypa angustifolia, should be used.

It is important to explore the tourism potential within a region and to develop a tourism management strategy. Yeh Bakung Beach has tourism appeal. Between the shore and the sea, the coast acts as a stabilizer, while also serving an aesthetic purpose. This is relevant for discussions on public preservation and welfare. People from outside Lalanglingah village use Yeh Bakung Beach not only as a tourist destination, but also as a location for Melasti (a Hinduism ceremony). This research was conducted in Yeh Bakung Beach, Lalanglinggah village, in Tabanan district. The following criteria were considered: condition of the location for tourism, market potential, accessibility, environmental factors, public service, climate change, accommodation, facilities and infrastructure, availability of clean water, safety and convenience, relation to other tourist attractions, area carrying capacity, visitor adjustment, marketing, and market share. The findings showed that Yeh Bakung Beach has good potential to become an ecotourism destination.

Effect of Rhizobacteria and Palm Mill Byproducts on the Growth of Oil Palm Seedlings in a Pre-Nursery
Authors: Hastuti Pauliz Budi , Wilisiani Fariha , Gunawan Sri , Lumban Gaol Jhon Lewis , Setyawan Heri
Published: June 2022

Plant growth-promoting rhizobacteria (PGPR) is a type of microbe that can boost root development and plant growth by interacting with plant roots. The goal of this study was to examine how oil palm mill byproducts and PGPR can affect oil palm seedling growth in a pre-nursery. The study was conducted using a completely randomized design with factorial treatments. The empty oil palm bunches (EFB) were divided into three levels: soil:compost EFB (1:1), soil:ash EFB (1:1), and a control soil. The second variable was the PGPR dose, which was divided into three levels: chemical fertilizer (control), 20 ml, and 30 ml. Each treatment combination was repeated five times. The research findings were analyzed using analysis of variance to determine the true difference between the treatments tested using Duncan’s multiple range test at 5%. There was no interaction between the administration of EFB and the dose of PGPR in the growth of pre-nursery oil palm seedlings, according to the findings. Oil palm seedlings grew well in EFB compost in a pre-nursery setting. In pre-nursery palm head seedlings, PGPR application at a dose of 20 ml was able to provide good growth.

Authors: Suartini Ni Made , Sudatri Ni Wayan
Published: June 2022

Pila scutata is a species belonging to the Ampullariidae family. One of the habitats of the snail is rice fields. Snails are used as an alternative protein source in Bali. The focus of this research was to determine the snail density, morphology, morphometry, and egg clusters in rice fields in the Selat District of the Karangasem Regency in Bali. Snails were collected in the morning by erecting a 1m x 1m quadrat in each corner of the rice field. Snails ranging in size from small to large were collected in the quadrats, on the surface of the water, in the water, and attached to aquatic plants. Snail egg clusters were discovered while exploring the rice fields where snail samples were collected. Sampling was repeated three times. Snail and egg cluster samples were brought to the lab for examination. The density, frequency of presence, distribution pattern, morphology, and morphometry of the snails were all calculated. The number of eggs in one egg cluster was determined by separating each egg from the egg cluster. According to the findings, the snail density was 3.75 individuals/m2, the presence frequency was absolute, and the distribution pattern was regular. The shell height was 17.02-31.09 mm, and the snails had a subglobose shape with brown transverse band. A single egg cluster could contain 29-67 eggs.

The purpose of this study was to determine the impact of adding dragon fruit(Hylocereussp) peel juice (DFPJ) to drinking water on the percentage of carcasses, and external and internal offal organs of free-range village chickens (White Gold &Lamcy). The study was carried out foreight weeks using a completely randomized design, which included 16 units (four levelsof DFPJ andfour replications of each, withfive birds per replication, for a total of 80 birds). The following treatmentswere given: R0: no DFPJ, R1: 5% DFPJ, R2: 10% DFPJ, and R3: 15% DFPJ in 1liter of drinking water. The variables observedwere: carcass percentage, and the percentage of external and internal offal organs.The results showed that the percentage of carcasses of the native chickens reared in free range were significantly different with the R2 and R3 treatments, while the R0 and R1 treatments had no effect on the internal and external offal organs of the chickens. It can be concluded that giving 10% or 15% dragon fruit peel juice through drinking water can have a significant effect on chicken carcass percentage, whereas using 5% does not have an effect.

Every country in the world, including Indonesia, is confronted with the problem of waste and is attempting to find viable solutions. The majority of recycled waste is inorganic waste, while there is also organic recycled waste, and the remaining 60-75%of waste is dumped in a landfill. By utilizing waste and by-products, bioconversion with black soldier fly (BSF) larvae could be a solution to help overcome the problem of organic waste; these larvae can also be used as a protein source in animal feed and in organic fertilizers rich in nutrients. The use of BSF as a decomposer of organic waste, specifically Black Soldier Fly Fertilizer (BSF Frass), and the liquid resulting from the bioconversion process, called micro biostimulant (MBS), can be used to promote plant growth. The goal of this study was to assess how BSF Frass affected plant growth when compared to Synthetic fertilizers. Corn and Pak Choi were the test plants that were planted in the field. The results showed that giving 50% BSF Frass to the tested plants resulted in better growth and development than the control.
