Muthuri; Shem Kuyah; Athanase Mukuralinda; Rumanzi S. Mbaraka; Gudeta W. Sileshi;Abstract Alnus acuminata Kunth. (alnus) has been widely promoted under climate change mitigation and adaptation programs in the East African highlands. However, information is lacking on the impact of its pruning management and green manure (GM) application on soil health and the productivity of associated crops. Using a large suit of soil quality indicators, crop growth and yield measurements, this study identified appropriate combinations of alnus pruning levels and GM application for sustainable intensification of potato (Solanum tuberosum) and wheat (Triticum aestivum) production. This study compared six treatments, namely, (1) sole crops of potato or wheat (control), (2) sole crop + GM, (3) 75% pruning, (4) 75% pruning + GM, (5) 90% pruning and (6) 90% pruning + GM. The best treatments were the 75% pruning + GM and 90% pruning + GM, which significantly differed from the control in soil pH, soil organic carbon (SOC), total nitrogen (TN), total phosphorus (P), exchangeable calcium (Ca) contents, the N:P and C:P stoichiometric ratios and the soil structural stability index (SSI). These treatments increased soil pH by 5–6%, SOC by 74–82%, TN by 58–68%, exchangeable Ca by 76–81%, total P by 17–21%, the N:P ratio by 40%, C:P ratio by 43–51%, the SSI by 71–79%, potato tuber yields by 17–21% and wheat yields by 21–32% over the control. Therefore, it is concluded that pruning and application of alnus green manure have the potential to significantly improve soil health and crop productivity on degraded soils in the study area.

The main directions of state regulation of agriculture in Ukraine, according to the authors, are the introduction and development of various measures aimed at reducing the disparity in prices for industrial and agricultural products, creating conditions for food security for basic types of food, implementing effective land reform, training labor resources for agricultural enterprises, transforming socio-cultural infrastructure in rural areas, creating effective market and transport infrastructure in rural areas, the use of price and customs regulators to effectively support domestic agricultural producers. Ensuring the stable development of the agricultural sector of the economy requires certain efforts focused on the development of the socio-economic sphere of rural areas. The development of rural areas requires conditions for the activation of activities in rural areas that are not related to the production of agricultural products (tourism, electricity production from renewable energy sources, folk crafts), increasing the level of efficiency in using the natural and labor potential of rural areas, improving the quality of medical services for the rural population and improving the functioning of the rural socio-cultural sphere.

The energy industry is entering the stage of the 4th energy transition, which is characterized by an increasingly large-scale increase in the use of renewable energy sources and a decrease in the share of fossil fuels. The energy sector is also strongly influenced by the trend of digital transformation and the use of digital technologies. The aim of the work is to study the possibility and conditions of using digital business models by companies in the energy sector to improve competitiveness and market growth. To achieve the goal of the study, the following tasks were set: to analyze the main trends and the state of digitalization of the energy industry; analyze digital business models and assess the possibilities of their use by energy companies; to formulate approaches to transforming the activities of energy companies in the transition to a digital business model. The authors hypothesized that the use of digital business models will allow energy companies to remain competitive and gain access to new markets by introducing new technologies. To conduct the study, the methods of microeconomic and industry analysis, systemic and comparative analysis, and analysis of the organizational behavior of the company were used. The results of the analysis showed that the global energy market is characterized by growth in dynamics and volatility. In order to adapt to changing conditions and maintain competitiveness, energy companies need to take advantage of digitalization and shape a digital strategy. One of the basic elements of an organization’s digital strategy is a successful digital business model. The article discusses the types and features of digital business models, and also formulates approaches to transforming the activities of energy companies in the transition to a digital business model.

Due to their fragility and the high demand for forest goods and services, tropical dry forests are also subject to one of the highest rates of deforestation and degradation. These disturbances affect the amount, input and the availability of woody debris, depending on the disturbance regime. This study aimed to quantify the C stocks in necromass and soil pools of Mecrusse woodlands under different disturbance regimes. C stock values for the different necromass components were consistently larger for the most disturbed Mecrusse woodlands. Consequently, soil organic matter and soil organic C (SOC) mass fractions and SOC stock were also larger for the most disturbed Mecrusse woodlands. Most C stock was from intact coarse woody debris (CWD). Overall, C stored in necromass was 37.7 Mg ha−1, of which 58.2% was from aboveground CWD, 30.3% from belowground necromass, and 11.4% from litter and fine woody debris. The majority of aboveground necromass was fallen CWD (54.6%), standing CWD ranked next (30%). The densities of intact, partially decayed, and rotten CWD were 98.7%, 83.2%, and 56.9% that of living trees, respectively. SOC stock was 39.7 Mg ha−1 for the whole population. Human pressure has led to more necromass and SOC stock.

Preferential development of technical creativity of students in robotics is pointed out in additional education system. The practice of introducing robotics into the academic process is still at the initial stage of its development and is not always efficient. In this study, educational robotics is considered as an element of polytechnic orientation of the academic process. The possibility of its use as a special educational technology in classes on subjects of science and math cycle is substantiated. Three areas of professional work of the teacher are distinguished in the structure of the technology: robotics as an object of study, as a tool of cognition and as a means of teaching, development and upbringing of students. The paper reveals the activity of the teacher in each direction. The results of teaching experience of the authors related to the application of this technology in teaching physics are presented.

Estuaries are important nursery areas for many species and these habitats are often affected by anthropogenic activities. We investigate possible negative effects of pesticides and metals on penaeid shrimps in Maputo Bay, Mozambique. Shrimps and water samples were collected in three estuaries and one coastal area for biomarker and chemical analysis. Acetylcholinesterase (AChE) and glutathione-S transferase activities were analysed as biomarkers for pollutants. 37 different pesticides were analysed in water samples and shrimp muscle tissue was analysed for 10 metals. Risk assessment showed that the environmental thresholds were exceeded for several herbicides in three of four of the assessed nursery areas. Lower AChE activities were detected in shrimps captured close to an agriculture area and this location had the lowest shrimp densities. Metal analysis in shrimp showed low levels. Despite localized effects, results highlight the need to improve the regulation of pollutants in the Espírito Santo estuary in Maputo bay.

AbstractThis paper describes a new neural network‐based approach to estimate ionospheric critical plasma frequencies (f0F2) from Global Navigation Satellite Systems (GNSS)‐vertical total electron content (TEC) measurements. The motivation for this work is to provide a method that is realistic and accurate for using GNSS receivers (which are far more commonly available than ionosondes) to acquire f0F2 data. Neural networks were employed to train vertical TEC and corresponding f0F2 observations respectively obtained from closely located GNSS receivers and ionosondes in various parts of the globe. Available data from 52 pairs of ionosonde‐GNSS receiver stations for the 17‐year period from 2000 to 2016 were used. Results from this work indicate that the relationship between f0F2 and TEC is mostly affected by the seasons, followed by the level of solar activity, and then the local time. Geomagnetic activity was the least significant of the factors investigated. The relationship between f0F2 and TEC was also shown to exhibit spatial variation; the variation is less conspicuous for closely located stations. The results also show that there is a good correlation between the f0F2 and TEC parameters. The f0F2/TEC ratio was generally observed to be lower during enhanced ionospheric ionizations in the day time and higher during reduced ionospheric ionizations in the nights and early mornings. The analysis of errors shows that the model developed in this work (known as the NNT2F2 model) can be used to estimate the f0F2 from GNSS‐TEC measurements with accuracies of less than 1 MHz. The new approach described in this paper to obtain f0F2 based on GNSS‐TEC data represents an important contribution in space weather prediction.

description Publicationkeyboard_double_arrow_right Article , Preprint 2022Publisher:Research Square Platform LLC Athanase R. Cyamweshi; Catherine W. Muthuri; Shem Kuyah; Athanase Mukuralinda; Rumanzi S. Mbaraka; Gudeta W. Sileshi;Abstract Alnus acuminata Kunth. (alnus) has been widely promoted under climate change mitigation and adaptation programs in the East African highlands. However, information is lacking on the impact of its pruning management and green manure (GM) application on soil health and the productivity of associated crops. Using a large suit of soil quality indicators, crop growth and yield measurements, this study identified appropriate combinations of alnus pruning levels and GM application for sustainable intensification of potato (Solanum tuberosum) and wheat (Triticum aestivum) production. This study compared six treatments, namely, (1) sole crops of potato or wheat (control), (2) sole crop + GM, (3) 75% pruning, (4) 75% pruning + GM, (5) 90% pruning and (6) 90% pruning + GM. The best treatments were the 75% pruning + GM and 90% pruning + GM, which significantly differed from the control in soil pH, soil organic carbon (SOC), total nitrogen (TN), total phosphorus (P), exchangeable calcium (Ca) contents, the N:P and C:P stoichiometric ratios and the soil structural stability index (SSI). These treatments increased soil pH by 5–6%, SOC by 74–82%, TN by 58–68%, exchangeable Ca by 76–81%, total P by 17–21%, the N:P ratio by 40%, C:P ratio by 43–51%, the SSI by 71–79%, potato tuber yields by 17–21% and wheat yields by 21–32% over the control. Therefore, it is concluded that pruning and application of alnus green manure have the potential to significantly improve soil health and crop productivity on degraded soils in the study area.

The main directions of state regulation of agriculture in Ukraine, according to the authors, are the introduction and development of various measures aimed at reducing the disparity in prices for industrial and agricultural products, creating conditions for food security for basic types of food, implementing effective land reform, training labor resources for agricultural enterprises, transforming socio-cultural infrastructure in rural areas, creating effective market and transport infrastructure in rural areas, the use of price and customs regulators to effectively support domestic agricultural producers. Ensuring the stable development of the agricultural sector of the economy requires certain efforts focused on the development of the socio-economic sphere of rural areas. The development of rural areas requires conditions for the activation of activities in rural areas that are not related to the production of agricultural products (tourism, electricity production from renewable energy sources, folk crafts), increasing the level of efficiency in using the natural and labor potential of rural areas, improving the quality of medical services for the rural population and improving the functioning of the rural socio-cultural sphere.

The energy industry is entering the stage of the 4th energy transition, which is characterized by an increasingly large-scale increase in the use of renewable energy sources and a decrease in the share of fossil fuels. The energy sector is also strongly influenced by the trend of digital transformation and the use of digital technologies. The aim of the work is to study the possibility and conditions of using digital business models by companies in the energy sector to improve competitiveness and market growth. To achieve the goal of the study, the following tasks were set: to analyze the main trends and the state of digitalization of the energy industry; analyze digital business models and assess the possibilities of their use by energy companies; to formulate approaches to transforming the activities of energy companies in the transition to a digital business model. The authors hypothesized that the use of digital business models will allow energy companies to remain competitive and gain access to new markets by introducing new technologies. To conduct the study, the methods of microeconomic and industry analysis, systemic and comparative analysis, and analysis of the organizational behavior of the company were used. The results of the analysis showed that the global energy market is characterized by growth in dynamics and volatility. In order to adapt to changing conditions and maintain competitiveness, energy companies need to take advantage of digitalization and shape a digital strategy. One of the basic elements of an organization’s digital strategy is a successful digital business model. The article discusses the types and features of digital business models, and also formulates approaches to transforming the activities of energy companies in the transition to a digital business model.

Due to their fragility and the high demand for forest goods and services, tropical dry forests are also subject to one of the highest rates of deforestation and degradation. These disturbances affect the amount, input and the availability of woody debris, depending on the disturbance regime. This study aimed to quantify the C stocks in necromass and soil pools of Mecrusse woodlands under different disturbance regimes. C stock values for the different necromass components were consistently larger for the most disturbed Mecrusse woodlands. Consequently, soil organic matter and soil organic C (SOC) mass fractions and SOC stock were also larger for the most disturbed Mecrusse woodlands. Most C stock was from intact coarse woody debris (CWD). Overall, C stored in necromass was 37.7 Mg ha−1, of which 58.2% was from aboveground CWD, 30.3% from belowground necromass, and 11.4% from litter and fine woody debris. The majority of aboveground necromass was fallen CWD (54.6%), standing CWD ranked next (30%). The densities of intact, partially decayed, and rotten CWD were 98.7%, 83.2%, and 56.9% that of living trees, respectively. SOC stock was 39.7 Mg ha−1 for the whole population. Human pressure has led to more necromass and SOC stock.

Preferential development of technical creativity of students in robotics is pointed out in additional education system. The practice of introducing robotics into the academic process is still at the initial stage of its development and is not always efficient. In this study, educational robotics is considered as an element of polytechnic orientation of the academic process. The possibility of its use as a special educational technology in classes on subjects of science and math cycle is substantiated. Three areas of professional work of the teacher are distinguished in the structure of the technology: robotics as an object of study, as a tool of cognition and as a means of teaching, development and upbringing of students. The paper reveals the activity of the teacher in each direction. The results of teaching experience of the authors related to the application of this technology in teaching physics are presented.

Estuaries are important nursery areas for many species and these habitats are often affected by anthropogenic activities. We investigate possible negative effects of pesticides and metals on penaeid shrimps in Maputo Bay, Mozambique. Shrimps and water samples were collected in three estuaries and one coastal area for biomarker and chemical analysis. Acetylcholinesterase (AChE) and glutathione-S transferase activities were analysed as biomarkers for pollutants. 37 different pesticides were analysed in water samples and shrimp muscle tissue was analysed for 10 metals. Risk assessment showed that the environmental thresholds were exceeded for several herbicides in three of four of the assessed nursery areas. Lower AChE activities were detected in shrimps captured close to an agriculture area and this location had the lowest shrimp densities. Metal analysis in shrimp showed low levels. Despite localized effects, results highlight the need to improve the regulation of pollutants in the Espírito Santo estuary in Maputo bay.

AbstractThis paper describes a new neural network‐based approach to estimate ionospheric critical plasma frequencies (f0F2) from Global Navigation Satellite Systems (GNSS)‐vertical total electron content (TEC) measurements. The motivation for this work is to provide a method that is realistic and accurate for using GNSS receivers (which are far more commonly available than ionosondes) to acquire f0F2 data. Neural networks were employed to train vertical TEC and corresponding f0F2 observations respectively obtained from closely located GNSS receivers and ionosondes in various parts of the globe. Available data from 52 pairs of ionosonde‐GNSS receiver stations for the 17‐year period from 2000 to 2016 were used. Results from this work indicate that the relationship between f0F2 and TEC is mostly affected by the seasons, followed by the level of solar activity, and then the local time. Geomagnetic activity was the least significant of the factors investigated. The relationship between f0F2 and TEC was also shown to exhibit spatial variation; the variation is less conspicuous for closely located stations. The results also show that there is a good correlation between the f0F2 and TEC parameters. The f0F2/TEC ratio was generally observed to be lower during enhanced ionospheric ionizations in the day time and higher during reduced ionospheric ionizations in the nights and early mornings. The analysis of errors shows that the model developed in this work (known as the NNT2F2 model) can be used to estimate the f0F2 from GNSS‐TEC measurements with accuracies of less than 1 MHz. The new approach described in this paper to obtain f0F2 based on GNSS‐TEC data represents an important contribution in space weather prediction.
