Published: May 2022

Chlorophyll-a (chla) is an important parameter to assess water quality in lakes and reservoirs, since it is a proxy for phytoplankton biomass and primary production. The increasing availability of data with high spatial and temporal resolution allows assessing short-term dynamics and small-scale variations of chla within larger water bodies. In freshwater reservoirs, the nutrient concentrations and the physical conditions that control phytoplankton growth vary along their longitudinal extend. Here, we analyze how the flow paths of the inflowing river water into density-stratified reservoirs affect the vertical and longitudinal distribution of nutrients and chla. We combine spatially resolved and high-frequency measurements of chla from satellite remote sensing and in-situ sensors, with numerical simulations using a three-dimensional hydrodynamic model to assess the influence of density currents on chla dynamics along a subtropical drinking water reservoir in the south of Brazil. Chla did not have pronounced seasonal dynamics (4.9 ± 1.2 µg L−1, at the continuous measurement station); instead, spatial variability along the reservoir was more pronounced (4.4 ± 2.1 µg L−1, all monitored points within the euphotic zone). Most of the nutrients from the inflowing river were consumed in the upstream region, and phytoplankton in the lacustrine zone depended on internal loading. Temporal variability was observed only in the upstream region, and phytoplankton produced in that area was transported downstream by density currents, resulting in large concentrations of chla below the euphotic zone. The results of a hydrodynamic model that simulates the present state are in good agreement with the observations. Two simulated scenarios, where the density current patterns were altered, resulted only in slight variations in density currents, indicating that the influence of the main inflow was of minor relevance in chla concentrations in downstream regions of the reservoir. Our results highlight the importance of two-dimensional hydrodynamic processes in regulating phytoplankton dynamics in reservoirs.

Published: May 2022

Arsenic (As) contamination of groundwater is a global public health problem. Microorganisms have a great effect on the migration and transformation of arsenic. Studying the effect of microbial community structure and function on arsenic release in the groundwater environment of the riverbank filtration zone has important theoretical and practical significance. In this paper, in-situ monitoring technology and molecular biology technology were used to study the microbial community in the process of river water infiltration in the Shenyang Huangjia water source, China. The results showed that the structure, diversity and abundance of the microbial community in groundwater were closely related to the arsenic content. Proteobacteria was the dominant phylum in groundwater of the study area, and Acinetobacter, Pseudomonas, Sulfuritalea, Sphingomonas and Hydrogenophaga etc. were the main dominant bacterial genera. In addition to reducing and oxidizing arsenic, these functional microorganisms also actively participated in the biogeochemical cycle of elements such as iron, manganese, nitrogen and sulfur. There was a significant correlation between dominant bacteria and environmental factors. Fe/Mn had a significant positive correlation with As, which brought potential danger to the water supply in high iron and manganese areas.

Published: May 2022

For effective management of water quantity and quality, it is absolutely essential to estimate the pollution level of the existing surface water. This case study aims to evaluate the performance of twelve machine learning (ML) models, including five boosting-based algorithms (adaptive boosting, gradient boosting, histogram-based gradient boosting, light gradient boosting, and extreme gradient boosting), three decision tree-based algorithms (decision tree, extra trees, and random forest), and four ANN-based algorithms (multilayer perceptron, radial basis function, deep feed-forward neural network, and convolutional neural network), in estimating the surface water quality of the La Buong River in Vietnam. Water quality data at four monitoring stations alongside the La Buong River for the period 2010–2017 were utilized to calculate the water quality index (WQI). Prediction performance of the ML models was evaluated by using two efficiency statistics (i.e., R2 and RMSE). The results indicated that all twelve ML models have good performance in predicting the WQI but that extreme gradient boosting (XGBoost) has the best performance with the highest accuracy (R2 = 0.989 and RMSE = 0.107). The findings strengthen the argument that ML models, especially XGBoost, may be employed for WQI prediction with a high level of accuracy, which will further improve water quality management.

Published: May 2022

Human alterations, such as hydropower development, are intensive and have negative impacts on fish and ecological environment. However, fish habitat restoration projects based on geographical morphology have not yet been reported in the Yangtze River. To explore engineering measures used to restore fish habitat structure and function, a mesoscale fish habitat restoration project was designed and constructed, which included restructuring of habitat topography in the fluctuating area. Three-dimensional computational fluid dynamics (CFD) models were used to simulate and predict the project’s effect on the hydromorphology prior to construction, and an Acoustic Doppler current profiler (ADCP) was deployed to test and verify actual flow field improvement. Short-term effects on fish species sorting and their main ecological traits were examined. The results showed that vorticity and flow heterogeneity in the river reach increased, suggesting that the restoration projects created flow conditions favourable to indigenous fishes. Thus, pre-optimization using computer simulation is an essential and scientific procedure that could be used to increase the probability of river restoration success. The promotion of habitat diversity had strong effects on fish aggregation, especially for the rare and endemic fish species targeted. Fish abundance, catch biomass and species richness increased by 98.1%, 62.7% and 22.5%, respectively. There were significant differences (p < 0.05) in species number and catch abundance before and after the project. The number of rare and endemic fish species increased from four to nine species. Overall, this research provides evidence that the promotion of habitat hydraulic morphology heterogeneity accelerates the recovery of fish diversity and biomass.

As the most effective irrigation method in arid and semi-arid regions, drip irrigation under mulch could general comprehension of the production efficiency of agricultural irrigation water, and reduce agriculture consumption of water resources. The paper has carried out an investigation over a two year period (2020–2021) in a semi-arid climate in the Hexi Oasis region of China, aiming at determining the influence of regulated deficit irrigation (RDI) under mulch on the growth, yield, water use efficiency (WUE), irrigation water use efficiency (IWUE) and quality of pumpkin at different growth stages. A total of nine treatments with three irrigation levels (75–85% field capacity, 65–75% field capacity, and 55–65% field capacity) have been used in four growing periods of pumpkin (seedling, vine extension, fruit expansion, and maturation stages). The results have shown that light water deficit treatment at the seedling stage had the highest water use efficiency (12.47 kg/m3) without significantly affecting yield (45,966.90 kg/ha), and improved pumpkin fruit quality. It was concluded that light water deficit at the seedling stage and adequate irrigation at other development stages was the optimal irrigation strategy for pumpkin growth. The results of this research provide theoretical and technical support for efficient water-saving plantation and industrialization of pumpkin in the Hexi Oasis.
EU relations with Afghanistan: a new reality
Authors:   Diplomatic Academy of the Ministry of Foreign Affairs of Russia, Mozel Konstantin N.
Published: May 2022

This article analyzes the EU's position after the hasty withdrawal of U. S. troops from Afghanistan. The EU was skeptical about the U. S. withdrawal, considering it a violation of its alliance with the Europeans. There is a very definite trend in the relationship between the European Union and the Taliban. The EU does not yet recognize the movement politically but is willing to cooperate with the new Afghan authorities on certain terms, taking into account the economic and financial crisis that has broken out in that country. A key influence on the relationship between the U. S., the EU and other countries with geopolitical influence will be the financial issue. They also noted that it is the lack of funds that will prevent the Taliban from strengthening control of Afghanistan. For the Taliban, the only sensible way out is to think about diplomatic ties with other countries seeking to spread influence in South Asia and, if possible, gain their loyalty. This includes, above all, Afghanistan's neighbors such as Iran, Pakistan, Turkey and India, but also major powers such as Russia and China. How active contacts with the new Afghan authorities will be, the EU will decide by observing the concrete actions of the Taliban and the new Afghan government. The chaotic withdrawal of U. S. troops from Afghanistan has had serious military and political implications for the EU and has catalyzed a debate on how to build up its military capabilities to secure its own interests. Russia, as Afghanistan's closest neighbor, is seriously interested in security and stability in the region and is in favor of maintaining civil peace and avoiding violence in the country, as well as establishing a real inter-Afghan dialogue.

The article discusses the theoretical foundations of the analysis and forecasting of financial risk in the banking sector in conditions of market uncertainty. The relevance of the study lies in the fact that the growth of problem debts of commercial banks on loans to legal entities, individual entrepreneurs and individuals is currently the most relevant and debated issue in the banking community. The analysis of the dynamics of assets and the share of overdue loans in 2010–2021 has been carried out, trends in portfolio changes have been identified. The authors considered the advantages of using the VaR indicator as a measure of risk, noting that its weak side is the inability to assess extreme losses (in the tails) if the risk is realized in the range above the confi dence interval. The Perseptron program has been developed for forecasting the dynamics of the share of overdue loans in the portfolio of a commercial bank, which is formed on the Deductor platform. Quantization (grouping) of data was carried out using a neural network on the Deductor platform, which made it possible to identify certain patterns in the change in portfolio quality. It was revealed that the value of the share of overdue loans of commercial banks is influenced by many factors, including factors included in the AI-system, so four parameters are placed on the input layer of the perceptron (%): growth in assets, market share, change in the loan portfolio, dynamics of overdue loans. The output layer has one parameter: forecast of the share of overdue loans (%). In addition to the input layer, the neural network architecture has two hidden layers, and an output layer with one parameter. The neural network shows high forecast accuracy. The error rate for Post Bank was 1.2159 %. The authors consider a wide range of financial mathematics tools proposed by the authors in order to assess and minimize financial risks, including quantile hedging, deficit hedging with minimal risk, and optimal quadratic hedging.

En Ecuador, el cultivo de amaranto (Amaranthus quitensis) está adquiriendo cada vez mayor importancia debido al incremento en la demanda, sin embargo, existe hasta la fecha un escaso conocimiento sobre las variedades y los diferentes sistemas de siembra que optimicen su producción. En tal sentido, en la presente investigación se evaluó el efecto de la asociación con chocho (Lupinus mutabilis) y habas (Vicia faba) sobre los parámetros agronómicos del cultivo de amaranto bajo las condiciones del cantón Cevallos, provincia de Tungurahua. El amaranto fue sembrado a diferentes distancias de siembra (0,4; 0,6 y 0,8 m) y luego de 30 días se realizó la siembra de las especies de leguminosas (chocho y haba) y fueron evaluadas las variables altura de planta, diámetro de tallo y rendimiento (expresado como el peso total de la semilla en Kg/ ha). Los resultados mostraron que el rendimiento del amaranto varió de acuerdo con el tipo de asociación de plantas, observándose que, los mayores valores fueron obtenidos cuando este se sembró en asociación con chocho, siendo superior cuando se usó una distancia de siembra de 60 cm. Con relación a la altura de planta, el mayor valor fue alcanzado cuando el amaranto fue sembrado en asociación con plantas de haba a una distancia de 0,40 y 0,60 m y cuando se usó la asociación con chocho a 0,40 m. Finalmente, el diámetro del tallo también mostró diferencias por efecto del tipo de asociación, obteniéndose el mayor valor en la asociación amaranto + haba a una distancia de 0,60 m. En vista del efecto positivo sobre los parámetros productivos de la planta de amaranto, es posible concluir que, bajo las condiciones evaluadas, la asociación de A. quitensis con leguminosas podría ser una opción promisoria.

Published: May 2022

Ler desempenha um papel fundamental nos processos de interação crítica com o mundo social e com a cultura, fomenta a ampliação da autonomia e contribui para a percepção de singularidades humanas diversas. No entanto, as poucas oportunidades de formação continuada dos professores e as escassas interlocuções da universidade com a comunidade escolar vão na contramão da consolidação de políticas públicas voltadas à promoção dessa aprendizagem. Diante disso, este artigo objetiva discutir espaços e ampliar possibilidades de encontro e de pesquisa com professores e estudantes dos anos finais do Ensino Fundamental, com vistas a mobilizar subsídios teóricos e ações práticas diferenciadas que culminem na implementação de um projeto multidisciplinar de tematização da leitura.

Este estudo, a partir de uma revisão narrativa de literatura, objetivou analisar as principais complicações e suas prevalências nas cirurgias de abdominoplastia em pacientes submetidos àintervenção bariátrica. Segundo a Sociedade Brasileira de Cirurgia Bariátrica e Metabólica, a cirurgia bariátrica é o tratamento mais eficaz para obesidade moderada àgrave. Contudo, apesar dos inúmeros benefícios, este tipo de procedimento tem como consequência flacidez com excesso de pele e de tecido subcutâneo, principalmente no abdômen. Isso afeta a qualidade de vida dos pacientes que são submetidos a essa cirurgia. Portanto, para remodelar o contorno do corpo e diminuir o excesso de pele, preconiza-se a realização da abdominoplastia. Devido aos diferentes biotipos, comorbidades e deficiências nutricionais dos pacientes, ao tipo de intervenção cirúrgica e à complexidade do procedimento, há risco aumentado de complicações em pacientes pós-bariátricos, com alta taxa de prevalência. Dentre os principais problemas estão: seroma, infecção, deiscência, atelectasia, porém, ainda, é necessária uma investigação sobre cada modo cirúrgico e as principais complicações relacionadas a ele, além de um trabalho multiprofissional para determinar a melhor técnica para cada paciente, a fim de reduzir os riscos de complicações.

Битумы являются одним из продуктов нефтепереработки. На свойства битумов влияет сам источник нефти и технологический процесс переработки нефти. Большинство европейских нефтеперерабатывающих заводов, конечно же, занимаются переработкой с целью перепродажи нефтепродуктов, особенно нефти, пригодной для извлечения легких и средних фракций. Поэтому необходимы легкие нефти с низкими выходами тяжелых фракций, которые высокоэкономичны и выгодны для переработчиков на нефтяном рынке. С точки зрения нефтепереработки содержание и соотношение асфальтенов и мальтенов, как обязательных компонентов битума, становится менее важным, однако это может существенно повлиять на будущие свойства битумного вяжущего. Основные тесты на температуру проникновения и размягчения предназначены для оценки свойств битума и классификации битума. Этих испытаний в настоящее время недостаточно, и поэтому разрабатываются новые методы и процедуры испытаний для определения характеристик битума. Основной темой подхода к оценке свойств битумных вяжущих, основанного на характеристиках, является оценка свойств с точки зрения характеристик дорожной одежды, таких как остаточная деформация, усталость и морозное растрескивание. Также важна оценка изменения свойств битума в процессе производства и укладки асфальтобетонной смеси. Исследование направлено на изучение вязкостно-температурного поведения и фундаментальных свойств, представленных пенетрацией и температурой размягчения образцов дорожного покрытия.

Bitumen is one of the products of oil refining. The properties of bitumen are affected by the source of oil itself and the technological process of oil refining. Most European refineries, of course, are refining for the purpose of reselling petroleum products, especially oil suitable for the recovery of light and medium fractions. Therefore, there is a need for light crudes with low heavy ends yields that are highly economical and beneficial to refiners in the oil market.From the point of view of oil refining, the content and ratio of asphaltenes and maltenes, as essential components of bitumen. becomes less important, but it can significantly affect the future properties of the bituminous binder. The basic penetration and softening temperature tests are designed to evaluate the properties of bitumen and classify bitumen. These tests are not currently sufficient and therefore new test methods and procedures are being developed to characterize bitumen. The main topic of the performance-based approach to assessing the properties of bituminous binders is the assessment of properties in terms of pavement characteristics such as set, fatigue and frost cracking. It is also important to assess the change in the properties of bitumen during the production and laying of the asphalt mix. The study is aimed at studying the viscosity-temperature behavior and fundamental properties represented by penetration and softening temperature of pavement samples.

A classic character brought to myth rank, Cervantes’s Quixote was tackled philosophically, by Miguel de Unamuno in his essay Vida de Don Quixote y Sancho, 1905 on the realm of Spanish literature; we have been recently amazed from a postmodern, even postcolonial perspective, by Salman Rushie (Quichotte, 2019) and dramatically on the stage of the National Theatre of Iași by Carmen Dominte who initially proposed The Quixote Syndrome (2021) as a theatrical performance meant to be read. Without dealing with the adaptations in various arts (Minkus’s ballet), we will study the resilience of a character with reference to the above texts and what was left of it on stage with insights into adaptation theory and theatrical interpretation in the context of pandemic distancing.
Ionesco Obsessions in Scenic Imagery Signed Gábor Tompa

Among the reference creators in the Romanian theatrical space, but also internationally, the director Gábor Tompa had a constant attraction for the aesthetics of Eugene Ionescu's texts, which strongly influenced his path of perfection and ranking among the most important directors. In 1992, at the Hungarian Theater of Cluj, Gábor Tompa staged the memorable theater play The Bald Soprano, a performance that will represent one of the pillars of his later career. Then, in 2003, the theater performance elaborated by Gábor Tompa using the text Jacques or the Obedience, at the Hungarian Theater of Cluj, can be called a total one, in which the decryption of the Ionescian message was done with a lot of fantasy and suggestive black humor. In 2014, he rebuilt the The New Tenant on the stage of Nottara Theater in Bucharest. The staging was well received by the general public, but also by the theater people, also appreciated by the selection among the best performances in prestigious festivals of 2014. At the beginning of 2020, Rhinoceros appears to Gábor Tompa as an extremely percussive text, which determines its staging at the Mihai Eminescu National Theater of Timişoara, enjoying an authentic success. Until now, the stage imagery signed by Gábor Tompa, will remain a reference page of theatrical constructions and Eugene Ionesco's texts, real revelations, owning well-articulated messages on stage, reflecting socio-human realities and concurrently, a real urge to reflect.
