Published: July 2022

It is crucial to develop an effective and easily recoverable phosphate absorbent for the control of eutrophication problems in polluted rivers. In this study, a stable particulate adsorbent with a diameter of 5 mm synthesized from lanthanum, activated carbon, and zeolite (La-CZ) was developed, characterized, and tested for the removal of phosphate from wastewater in a small-scale reactor, which was designed to easily recycle La-CZ with a basket. Batch studies showed that La-CZ could reach adsorption equilibrium within 2 h and the maximum phosphate sorption capacity was 18.2 mg g−1. The experimental data showed good compliance with the Langmuir isotherm model and pseudo-second-order kinetic model, implying that chemisorption dominates the phosphate uptake process. La-CZ exhibited a stable adsorption capacity over a wide pH range (3–7), while the adsorption capacity decreased slightly under alkaline conditions. Although Nitrates (NO3−) and Carbonate (CO32−) had some effects, normal coexisting ions such as Chloride (Cl−), Sulfate (SO42−), and Fluorine (F−) had no significant effects on the phosphate adsorption capacity of La-CZ. The main form of phosphate removed from the reaction system was HCl-P (77.68%), as determined through phosphorus fractionation. In particular, this study designed a replaceable filler-type reactor integrating a reflux and aeration system, 98.8% of phosphorus could be removed from actual wastewater, and La-CZ could be reclaimed easily. This work provides an excellent reference for particulate adsorbents that can efficiently remove phosphate in practical applications in the future.

Published: July 2022

Dam reservoir operation plays a fundamental role in water management studies and planning. This study examined three policies to improve the performance of reservoirs: Standard Operation Policy (SOP), Hedging Rule (HR) and Multi-Objective Optimization (MOO). The objective functions were to minimize the LSR (Long-term Shortage Ratio) for HR and to minimize MAE (Mean Absolute Errors of released water) for SOP. MOO’s objective function was to reduce vulnerability and maximize reliability indexes. The research was conducted in two time periods (1985–2005 and 2025–2045). Combining EPO (Empire Penguin Optimization) algorithm and Gene Expression Programming (GEP) with elementary arithmetic (EOPba) and logical operators (EPOad) modified HR and SOP policies. Multi-Objective EPO (MPOEPO) and GEP with trigonometric functions were used to create a multi-objective policies formula. The results showed that the generation of the operation rules with EPOad increased the dam reservoir Performance Indexes (Vulnerability and Reliability Indexes) compared to EPOba. Moreover, HR application compared to SOP improves the mean dam reservoir’s Performance Indexes by about 12 and 33% in the baseline and 12 and 21% in the future period (climate change conditions), respectively. The MOO method (MOEPO) improved the Vulnerability and Reliability Indexes by about 36 and 25% in the baseline and by 31 and 26% in the future, respectively, compared to SOP.

Aquifers are ubiquitous, and their water is easy to obtain with low extraction costs. On many occasions, these characteristics lead to overexploitation due to important water level declines, reduction of river base flows, enhanced seawater intrusion, and wetland affection. The forecasted increase in water demands and global warming will impact the future availability of water resources. Conjunctive use of surface and subsurface waters can help in mitigating these impacts. There are two main conjunctive use strategies: artificial recharge (AR) and alternate conjunctive use (ACU). AR stores waters that are not to be used directly in aquifers. ACU utilizes groundwater in dry periods, while surface waters are preferred in wet ones; this allows the increase of water supply with lower dam storage, economic gains, and environmental advantages. Efficient conjunctive use can prevent soil salinization and waterlogging problems in semiarid countries due to excessive recharge from irrigation return flows or other origins. Groundwater is a neglected and generally misused resource to maintain environmental conditions. When considering the solution to a water resources problem, groundwater should always be part of the design as an alternative or a complementary resource. Aquifers have large inertia, and changes in their volumes are only noticeable after years of observations. Unfortunately, groundwater observation networks are much poorer than surface ones, something that should be changed if groundwater is to come to the rescue in these times of climate change. Human and material resources should be made available to monitor, control, analyze, and forecast groundwater.

Published: July 2022

Integrated rice field aquaculture, a practice normally used by rural small-scale farmers, is not only supporting farms and livelihoods but is also reducing poverty and is playing a more and more important role in China. It is also becoming one of the main freshwater aquaculture systems, in addition to ponds, lakes, reservoirs, streams, and other aquaculture systems. During the past 40 years, both the production and areas of integrated rice field aquaculture in China have significantly increased from 0.13 million t and 0.74 million ha in 1990 to 3.25 million t and 2.56 million ha in 2020, respectively. Advances in ecology research on integrated rice–fish aquaculture were one of the main contributors to this achievement. In this paper, we systematically reviewed the advances in ecology research on three major integrated rice field aquaculture systems in China, namely rice–fish, rice–crab, and rice–crayfish coculture systems, the contribution of the research, and future prospects. We found that progress in ecology research on theories, biological studies, models, and eco-engineering techniques, coupled with policy support promoted the development of the rice field aquaculture industries. This review could assist individual small-scale farmers to make better use of rice field space to produce safer aquatic and rice products at a lower cost and help aquaculture scientists to further study the ecology of integrated rice field aquaculture systems.
Flow at an Ogee Crest Axis for a Wide Range of Head Ratios: Theoretical Model
Authors: Stilmant Frédéric , Erpicum Sebastien , Peltier Yann , Archambeau Pierre , Dewals Benjamin , Pirotton Michel
Published: July 2022

The discharge coefficient of an ogee crest is a function of the ratio of the effective head to the design head. The purpose of the present study is to derive a theoretical model of this relation, which does not depend on empirical coefficients and whose predictions over a wide range of head ratios are accurate enough for practical use. The developments consider unsubmerged ogee crests without approach flow or lateral contraction effects, heads large enough to enable surface tensions to be neglected, and heads small enough to avoid flow separation. The method is based on potential flow theory, depth integration in a curvilinear reference frame, and critical flow theory. The characteristics of the crest shape are defined by the trajectory of a free jet passing over the crest at the design head. The dimensionless equations show that the position of the critical section is not at the apex of the crest. Nevertheless, they also suggest an approximate equation at the apex of the crest from which the discharge coefficient is derived, together with the local water depth, velocity, and pressure distribution. The results compare well with experimental data for head ratios between 0 and 5, which validates the underlying assumptions of the theoretical model.

Published: July 2022

The over-exploitation of coastal aquifers has led to seawater intrusion issues in many parts of the globe; this problem, which is associated with water recharge deficit and anthropogenic pollution, represents the main source of groundwater degradation in Santiago Island in the Republic of Cape Verde’s archipelago. Brackish groundwater for agriculture and human consumption is being provided to several areas on Santiago Island as the only type of available water. Chemical and isotopic data obtained in three main groundwater systems were used in the characterization of the groundwater resources and in the identification of the main source responsible for their degradation. The obtained results indicate water–rock interaction as the major process responsible for the groundwater quality reflecting its lithological composition. Carbonatite dissolution can be partially responsible for the calcium increase along the groundwater flow path. Isotopic data (δ2H, δ18O; 3H and 14C) combined with the water chemistry provided a wide characterization of the groundwater recharge and identification of salinization processes (like seawater intrusion and marine aerosols dissolution in different sectors of the island). In the eastern part of Santiago Island, a different isotopic pattern (2H-18O) was observed in the groundwater samples, which was likely ascribed to different climate conditions. Carbon-14 determinations indicate apparent groundwater ages between 3.5 and 5.1 ka BP.
Electric Vehicle Simulations Based on Kansas-Centric Conditions

Published: July 2022

Range anxiety is a significant contributor to consumer reticence when purchasing electric vehicles (EVs). To alleviate this concern, new commercial EVs readily achieve over 200 miles of range, as found by the United States Environmental Protection Agency (EPA). However, this range, measured under idealized conditions, is often not encountered in real-world conditions. As a result, this effort describes the simplest model that incorporates all key factors that affect the range of an EV. Calibration of the model to EPA tests found an average deviation of 0.45 and 0.57 miles for highway and city ranges, respectively, among seven commercial EVs. Subsequent predictions found significant losses based on the impact of road grade, wind, and vehicle speed over a Kansas interstate highway. For cabin conditioning, up to 57.8% and 37.5% losses in range were found when simulating vehicles at 20 °F and 95 °F, respectively. Simulated aging of the vehicle battery pack showed range losses up to 53.1% at 100,000 miles. Model extensions to rain and snow illustrated corresponding losses based on the level of precipitation on the road. All model outcomes were translated into an Excel spreadsheet that can be used to predict the range of a generic EV over Kansas-centric roads.

Published: July 2022

There is an exponential increase in electric vehicles on the road that need a follow up in terms of warranty. The proposed state of warranty (SOW) is a metastate that qualitatively describes the warranty fulfillment level of an electric vehicle. All the relevant warranty information is synthesized in a single merit while maintaining the level of detail through the qualitative substates. The developed SOW is calculated with a rule-based logic of an expert system that evaluates the quantitative value of three substates: the remaining warranty, the remaining health and the remaining useful warranty. The SOW provides a synthesized and user-friendly description of the warranty fulfillment state while providing quantitative detailed information of the most relevant features of each of the different maintenance methodologies.

Published: July 2022

The transport sector has to be widely decarbonized by 2050 to reach the targets of the Paris Agreement. This can be performed with different drive trains and energy carriers. This paper explored four pathways to a carbon-free transport sector in Germany in 2050 with foci on electricity, hydrogen, synthetic methane, or liquid synthetic fuels. We used a transport demand model for future vehicle use and a simulation model for the determination of alternative fuel vehicle market shares. We found a large share of electric vehicles in all scenarios, even in the scenarios with a focus on other fuels. In all scenarios, the final energy consumption decreased significantly, most strongly when the focus was on electricity and almost one-third lower in primary energy demand compared with the other scenarios. A further decrease of energy demand is possible with an even faster adoption of electric vehicles, yet fuel cost then has to be even higher or electricity prices lower.

Published: July 2022

This paper investigates and compares the torque-generating capabilities and electromagnetic performance of advanced non-overlapping winding induction machines (AIM), conventional induction machines (CIM), and interior-permanent magnet (IPM) machines for electric vehicle (EV) applications. All investigated machines are designed based on the specifications of the Toyota Prius 2010 IPM machine. The steady-state and flux-weakening performance characteristics are calculated by employing the 2D finite element method and MatLab, and the obtained results are quantitatively compared. Furthermore, the torque-generating capabilities of three machines are investigated for different electric loadings, and the machine having the highest torque-generating capability is determined as AIM. Moreover, the major parameters affecting the torque-generating capability, such as magnetic saturation and magnet demagnetization, are examined in depth.
Long-Term Variability of Wind Speed and Direction in the Mediterranean Basin
Authors: Soukissian Takvor , Sotiriou Maria-Aliki
Published: July 2022

In this work, the ERA5 reanalysis dataset, with its fine spatial and temporal resolution, is used to study the wind speed and direction characteristics in the Mediterranean basin from 1979 to 2020. Their variability, trend and mean values, as well as their association, are examined in the monthly, annual and interannual/decadal time scales. The long-term variability of the wind direction is assessed using the angular variance, while the mean annual and interannual variability are used for the wind speed. The most characteristic and constant flow systems appear in the Gulf of Lion (Mistral) and the Aegean Sea during the summer (Etesian winds). The mean annual variability maximizes in the northern part of the basin, while the western part appears to have the most variable wind directions, while the fastest increasing wind speeds appear in the southwestern Levantine sub-basin. The long-term linear trend for the mean, the 95th and 99th quantiles of annual wind speed and the number of occurrences of extreme wind events have been also assessed. For particular areas, there is an increasing tendency in both intensity and frequency of occurrence of extreme wind events. Τhe linear-circular correlation coefficient has been implemented in order to quantify the linear association between the wind direction and the wind speed. This parameter demonstrates higher annual values for the Mistral wind in the Gulf of Lion and the Etesian winds in the Aegean Sea during the summer. Finally, the comparison of the results of ERA5 with the results of ERA-Interim highlighted significant differences in the Mediterranean wind speed and direction characteristics.

In the European classifications of antidepressants (AD), the drug is called an antagonist of type 2 serotonin receptors and at the same time a serotonin reuptake inhibitor. In Russian classifications, trazodone is usually referred to as «specific serotonergic antidepressant» or «atypical antidepressant». Trazodone is the only representative in its class. Despite the fact that it was registered in Europe in the 70s, in terms of its receptor properties, good tolerability and safety profile, it belongs to the third generation of ADs and in some respects can be considered more modern than selective serotonin reuptake inhibitors (SSRIs). In terms of overall efficacy, it is comparable to other ADs, but due to the peculiarities of the mechanism of action, it is often effective in cases of depressive and anxiety disorders resistant to other ADs.

Published: July 2022

The relevance of cardiac glycosides is due to their selective effect on the heart, which provides the most effective action and increased performance. In this regard, they are used to treat heart failures of various etiologies and paroxysmal tachyarrhythmias in adults and children, as well as to control the frequency of ventricular contractions with a constant form of ventricular fibrillation. However, owing to the narrow breadth of the therapeutic action, that is, the range from therapeutic to toxic dose varies by about 50–60 %, cardiac glycosides require caution when used.

The physical development of children is rightfully considered one of the most important criteria for assessing health, since it takes into account not only the influence of environmental factors of abiotic and biotic nature, the socio-economic state of the region of residence, the presence or absence of diseases, but also hereditary predisposition, including developmental features characteristic of different ethnic groups. The physical development of newborns is one of the main indicators of the health of the child population and the general population in need of constant monitoring, which would allow to determine the features of growth and development formed in the conditions of a certain lifestyle and habitat of the mother during pregnancy, timely identify deviations from the normal level of physical development and develop measures to prevent and eliminate violations. The aim of the study was to conduct an index assessment of the physical development of newborns to identify regional characteristics. The article presents an index assessment of the physical development of newborns in the Altai Territory, by calculating the mass-growth index (Ketle-I) and the Erisman index. The study included full-term newborns of both sexes (776 girls and 1249 boys) born during 2014 in a maternity hospital in Barnaul. The following regional features of the physical development of newborns were established for the region: disharmonious development by the type of elongation, inconsistencies of longitudinal dimensions with transverse ones, as well as a high incidence of prenatal hypotrophy in children born in the cold months of the year, most likely explained by eating disorders, nutritional imbalance, as well as vitamin D deficiency during pregnancy in their mothers. The data obtained can be applied in the compilation of regional centile tables along with other methods of assessing the physical development of newborns.
Indicators of mental performance of lyceum students

Published: July 2022

The problem of forming and strengthening the health of children, preventing the occurrence of diseases is currently a key area of Russian education and health care due to the deterioration in the health of the younger generation. The share of school environment factors influencing the formation of students’ health is up to 30 %. In the educational system of a modern school, there is an intensification of the educational process. The complication of the curriculum in schools of a new type (lyceums, gymnasiums) requires long-term functional stress from schoolchildren, which worsens the state of the body, which is especially important for children with health problems. One of the criteria for the adaptation of the organism of schoolchildren to educational loads and their compliance with the functional capabilities of the central nervous system of students is the state of mental performance. In this regard, it is relevant to study the mental performance of schoolchildren belonging to different health groups. A survey of 130 girls and 160 boys of 11 years of age, students of the lyceum, who, after a comprehensive assessment of the state of health, were assigned to 1, 2, 3 health groups, was carried out. The quantitative and qualitative indicators of mental performance in the daily, weekly and annual dynamics of the academic year were analyzed. It is shown that children with chronic diseases in a compensated state successfully adapt to short-term educational loads, but have reduced resistance to long-acting factors of the educational process, which is confirmed by a significant decrease in qualitative and quantitative indicators of mental performance by the end of the school year. The significant decrease in mental performance at the end of the academic year among students of the 3rd health group, revealed as a result of the study, dictates the need for additional attention to the issue of hygienic regulation of the mode of activity of students with deviations from chronic diseases, as well as the development and use of health-saving training technologies.

The issues of forecasting the spread of diseases have been of particular importance for a long time, even more than 100 years ago, but over the past two decades there has been an increased interest in mathematical epidemiology in the world and in connection with the emergence of new and poorly studied infectious diseases. The purpose of this study is to analyze the trends in the development of morbidity forecasting in the modern conditions of the COVID-19 pandemic. Within the framework of the study, current literary and statistical data were provided, the analysis was based on various scientific publications on predicting the spread of diseases of the population in the Russian Federation and in the world; analysis of the situation and methods of combating the spread of a new coronavirus infection, the main factors affecting the spread of diseases were identified, the main characteristics were given and their significance was determined, such methods as: studying and generalizing experience, bibliographic, informational and analytical, statistical. Thus, methodological approaches to predicting the spread of diseases cannot be used separately from the entire existing healthcare system. As a result, competent planning of preventive and anti-epidemic measures is necessary, as well as effective allocation of health resources, especially during epidemics and pandemics; and the results of the study can serve as materials for further study of problems related to the threat of the spread of diseases, scientific search for solutions to the problems of the organization of the health system, as well as in the educational process at the stage of higher and additional medical education.

At the present stage of the crisis in the development of the economy, there is a modification of the management strategies of the largest economic entities — transnational companies (TNCs), associated with the emergence of fundamentally new models of business development, ubiquitous digitalization processes and digital transformation. The purpose of the analysis in this article is assessment of the potential and management aspects of the development of crossborder mergers and acquisitions at the present stage. The methodological basis of the study is the modern provisions of the theory of transnationalization, as well as concepts covering the processes of internationalization (in particular, the "springboard theory"). In preparing the article, the method of systems analysis was used, as well as the analytical method, which made it possible to formulate the main scientific abstractions about the strategies of cross-border mergers and acquisitions. The empirical basis of the study is provided by statistics on global foreign direct investment (FDI) flows, crossborder mergers and acquisitions, as well as corporate strategies of some companies. The current crisis, as well as digitalization processes, influence the formation of new management patterns for the development of these corporate strategies. In the postpandemic phase of development, cross-border M&A strategies are becoming more customer-centric. At the same time, the key risk of developing effective strategies for managing cross-border mergers and acquisitions is the growth of protectionist sentiments on the part of states, which determine the uncertainty of scientific and practical approaches to the further organization of such transactions. It has been established that from the point of view of managerial consequences, managers of TNCs considering foreign mergers and acquisitions should take into account the stage of internationalization at which the TNC is located, as well as the nature of the change in institutional regulation in their country.

Authors:   Moscow State Institute International Relations Ministry of Foreign Aff airs of the Russian Federation, Kruzhilin Petr Alekseevich
Published: July 2022

Today, against the backdrop of European sanctions against Russia, the idea of abandoning Russian energy resources is being actively promoted. The EU is focusing on substituting imports from Russia with imports from other countries and green energy. At the same time, there is exceptional volatility in the energy markets, we can talk about an energy crisis. The price that the EU pays for the rejection of Russian energy is extremely high, moreover, the crisis observed today in the European energy market is primarily associated with the rejection of cheap Russian energy. The article proves that the current situation is a crisis for the EU, it is linked to anti-Russian sanctions. The author proved that with a planning horizon of less than 10 years, the EU will not be able to fully abandon Russian energy sources, and green energy will not be able to replace oil and gas from the Russian Federation. Separately, the question of how green energy can be compared with traditional energy sources is investigated and it is proved that the latter can exist without green energy sources, while the former needs duplication.

Uso de biomasa algal en la elaboración de balanceados para nutrición animal
Authors: Vásquez Garcia Francisco Javier , Morales Avendaño Ever Dario
Published: July 2022

Resumen
Las algas poseen aporte proteico, de minerales, fibra, antioxidantes, prebióticos e inmunoestimulantes, características importantes de un alimento para la nutrición animal. Existen evidencias sobre inclusiones de harina de algas, demostrando ser una materia prima alternativa para la formulación de alimentos, debido a su aporte al rendimiento, digestibilidad, mejora de parámetros de salud, incluso favorece aspectos sensoriales en la carne de las especies del sector ganadero. La zona costera de Ecuador alberga una gran diversidad de especies de algas, de las cuales se dispone de poca información, acerca de sus propiedades nutricionales; para su consumo en la dieta animal y otros fines industriales. Estudios recientes han demostrado lo factible que es el uso de las harinas de microalgas, siendo las más utilizadas las de Spirulina (Arthrospira sp.) y Chlorella sp. y así como también, las de macroalgas; tales como Rhodymenia howeana y Palmaria palmata (rodofitas); además de Ulva sp. (clorofita) y de Lessonia trabeculata y Laminaria digitata (feofita). La presente revisión conforma una integración de los avances tecnológicos sobre el uso directo y producción de biomasa algal como materia prima en la elaboración de balanceados para nutrición animal, en especies productivas del sector caprino, bovino, acuícola, avícola, porcícola y cunícola.
