Published: May 2023

Water quality monitoring is essential for managing water resources and ensuring human and environmental health. However, obtaining reliable data can be challenging and costly, especially in complex systems such as estuaries. To address this problem, we propose a novel deep learning-based approach that uses limited available data to accurately estimate and reconstruct critical water quality variables, such as electrical conductivity, dissolved oxygen, and turbidity. Our approach included two tasks, numerical modeling and historical reconstruction, and was applied to the Seine River in the Normandy region of France at four quality stations. In the first task, we evaluated four deep learning approaches (GRU, BiLSTM, BiLSTM-Attention, and CNN-BiLSTM-Attention) to numerically simulate each variable for each station under different input data selection scenarios. We found that incorporating the quality data with the water level data collected at the various stations into the input data improved the accuracy of the water quality data simulation. Combining water levels from multiple stations reliably reproduced electrical conductivity, especially at stations near the sea where tidal fluctuations control saltwater intrusion in the area. While each model had its strengths, the CNN-BiLSTM-Attention model performed best in complex tasks with dissimilar input trends, and the GRU model outperformed other models in simple monitoring tasks with similar input-target trends. The second task involved automatically searching the optimal configurations for completing the missing historical data in sequential order using the modeling task results. The electrical conductivity data were filled before the dissolved oxygen data, which were in turn more reliable than the turbidity simulation. The deep learning models accurately reconstructed 15 years of water quality data using only six and a half years of modeling data. Overall, this research demonstrates the potential of deep learning approaches with their limitations and discusses the best configurations to improve water quality monitoring and reconstruction.

Published: May 2023

Oil spills are one of the most hazardous pollutants in marine environments with potentially devastating impacts on ecosystems, human health, and socio-economic sectors. Therefore, it is of the utmost importance to establish a prompt and efficient system for forecasting and monitoring such spills, in order to minimize their impacts. The present work focuses on the numerical simulation of the drift and spread of oil slicks in marine environments. The specific area of interest is the Azemmour estuary, located on Morocco’s Atlantic Coast. According to the environmental sensitivity index (ESI), given its geographical location at the intersection of the World’s Shipping Lines of oil transport, this area, as with many other sites in Morocco, has been classified as a high-risk area for oil spill accidents. By taking into account a range of factors, including the ocean currents, the weather conditions, and the oil properties, detailed numerical simulations were conducted, using the hydrodynamic TELEMAC-2D model, to predict the behavior and spread of an oil spill event in the aforementioned coastal region. The simulation results help to understand the spatial–temporal evolution of the spilled oil, the effect of wind on the spreading process, as well as the coastal areas that are most likely to be affected in the event of an oil spill accident. The simulations were performed with and without wind effects. The results showed that three days after the oil spill only 31% of the spilled oil remained on the sea surface. The wind was found to be the main factor responsible for oil drifting offshore. The results indicated that rapid action is needed to address the oil spill before it causes significant environmental damage and makes the oil cleanup process more challenging and expensive. The results of the present study are highly valuable for the management and prevention of environmental disasters in the Azemmour estuary area. The findings can be used to assess the efficacy of various response strategies, such as containment and cleanup measures, and to develop more effective emergency response plans.

Published: May 2023

Regular exercise paves the way to a healthy life. However, conventional sports events are susceptible to weather conditions. Current motion sensors for home-based sports are mainly limited by operation power consumption, single-direction sensitivity, or inferior data analysis. Herein, by leveraging the 3-dimensional printing technique and triboelectric effect, a wearable self-powered multidimensional motion sensor has been developed to detect both the vertical and planar movement trajectory. By integrating with a belt, this sensor could be used to identify some low degree of freedom motions, e.g., waist or gait motion, with a high accuracy of 93.8%. Furthermore, when wearing the sensor at the ankle position, signals generated from shank motions that contain more abundant information could also be effectively collected. By means of a deep learning algorithm, the kicking direction and force could be precisely differentiated with an accuracy of 97.5%. Toward practical application, a virtual reality-enabled fitness game and a shooting game were successfully demonstrated. This work is believed to open up new insights for the development of future household sports or rehabilitation.

Design and optimization of trajectories in the Jovian system are crucial technologies for Jupiter exploration missions due to the unique and challenging multi-body dynamical environment. Various methodologies have been proposed and developed. However, there is a lack of comprehensive review of these methodologies, which is unfavorable for further developing new design techniques and proposing new mission schemes. This review provides a systematic summarization of the past and state-of-art methodologies for 4 main exploration phases, including Jupiter capture, the tour of the Galilean moons, Jupiter global mapping, and orbiting around and landing on a target moon. For each exploration phase, the related methods are categorized according to the fundamental features. The advantages and capabilities of the methods are described or analyzed, revealing the research progress. Finally, a prospect of future development of the methods is presented, aiming at providing references for further studies on trajectory design and optimization in the Jovian system.

DESIGN AND ANALYSIS OF BIDIRECTIONAL BUCK-BOOST CONVERTER FOR GRID TO PHEVAND PHEV TO HOME
Authors: D Sharmila , Maruthupandi P
Published: May 2023

Nowadays, the use of Electric Vehicles (EV) is rapidly increasing. The batteries of the EV are charged when its demand is low, and the energy would then be stored to act as a kind of reserve that could be used when necessary. A new design of “bidirectional DC-DC buck boost converter” is suggested for transferring electrical power between the grid and an electric vehicle, as well as between an electric vehicle and the residence. While using grid energy to charge the car battery, the Grid to Vehicle (G2V) mode utilizes a buck mode DC-DC converter operation. The Vehicle to Home (V2H) function uses the battery's stored energy to power dwellings off the grid when the DC-DC converter is running in boost mode. The battery's Status of Charge is determined using an enhanced Kalman filter. Proportional-integral controllers are used in bidirectional buck boost converters to maintain a consistent voltage on both the high voltage and low voltage sides. Phase angle control is used for G2V and V2H operations on the H-Bridge inverter that the DC-DC converter is coupled with. The proposed circuit is simulated in MATLAB, and the results are reviewed.

DEVELOPMENT OF FORMS OF MODERN FRANCHISING
Authors:   Russian Academy of National Economy and Public Administration under the President of the Russian Federation, Pyshkina Anastasiya O.
Published: May 2023

Franchising as a business technology is not widely represented and in demand in the Russian business environment. But at the same time, the key advantages of franchising, while stabilizing the overall political and economic situation, make it possible to activate business activity in this business format. Moreover, the consumer services sector is the most dynamically developing segment of the service market, since the growth of the welfare of the population (projected in the medium term) and the growth of the quality of life will stimulate demand primarily in the service sector. However, in order for franchising, as an optimal business technology, to be developed in the Russian consumer services sector, the services provided by copyright holders to their franchisees must be characterized by an appropriate level of quality and sufficient efficiency. It follows from this that franchising networks need to develop their own business models. The article presents a practical analysis of the activities of a franchise network in the Russian Federation, identifying problems in its model and developing proposals aimed at business development.

Influences of electrical conductivity of the cylindrical walls on heat transfer enhancement of nanofluid swirling flow
Authors:   Department of Mechanical Engineering, University of Blida 1, 09000, Algeria, Madani Fateh , Mahfoud Brahim , Errahmane Mahfoud Hibet
Published: May 2023

The swirling nanofluid flow driven by a revolving bottom disk of a cylindrical container under magnetic field effect and temperature gradient is examined in this study. The effects of the electrical conductivity of cylindrical walls’ on heat transfer enhancement are quantitatively investigated. The finite volume approach is used to solve the governing equations under the appropriate assumptions. This study considers four cases of combined electric conducting and insulating walls. The solid nanoparticle (copper) with volume fraction (ϕ = 0.1) is added to water. Calculations were done for fixed Reynolds number (Re=1000), Richardson number (0≤Ri ≤2), and various Hartmann numbers. The mean Nusselt number decreased as the Richardson number increased owing to stratification layers. These latter restrict heat exchanges between the cylinder’s hot and cold zones. The results show that within a particular range of Hartmann numbers, the Nusselt number increases, especially when the revolving lid is electrically conducting. The best heat transfer occurs when all of the walls are electrically conductive, which results in a 100% improvement at low Richardson values. Finally, the electrical conductivity of the revolving lid was a key factor in enhancing heat transfer.

Published: May 2023

We synthesized a new tetraphenylethylene-modified chitosan bioconjugate, CS-TPE, that shows the aggregation-induced emission effect. It can self-assemble into fluorescent polymeric nanoparticles in an aqueous solution at pH 5.3 either alone or with the water-soluble bowl-shaped six-fold carboxylated tribenzotriquinacene derivative TBTQ-C6 via host–guest binding. The spherical nanoparticles formed by CS-TPE amphiphiles or TBTQ-C6/CS-TPE supra-amphiphiles disintegrated under alkaline stimulation at pH 10.4 and the dispersion of the aggregates after the collapse in the presence of TBTQ-C6 was greatly improved. In addition, the fluorescence of CS-TPE was significantly enhanced by introducing TBTQ-C6, and remained relatively stable with variations in pH for both CS-TPE and TBTQ-C6/CS-TPE. Such pH-responsive supramolecular spherical nanoparticles with stable fluorescence emission based on CS-TPE or TBTQ-C6/CS-TPE may find applications in various fields, including the development of visual oral drug delivery systems.

Multiple sclerosis is a demyelinating autoimmune disease in the central nervous system. It is associated with several factors, one of which is Helicobacter pylori. We suggested that HP may have different effects on MS in the acute and chronic phases; therefore, we evaluated the HP and MS association in acute and chronic phases of infection. Scopus, PubMed, and Web of Science databases were used for systematic search. Finally, according to the inclusion criteria, eight studies were selected. According to the result of this study, there was no significant difference in the disease duration and EDSS between MS with HP. Pooled results showed that the standard difference in the mean EDSS was - 0.910, and the standard difference in the mean duration was - 0.067. Also, by comparing antibody levels in the acute and chronic phases of HP with the control group. Finally, we evaluate the mean EDSS between the two phases of infection, which shows that the mean EDSS and the clinical weaknesses of MS in the acute phase were slightly higher than in the chronic. In conclusion, HP infection can have a stimulating or inhibiting effect on the immune system based on the onset and activity of the infection.

Invasive and metastatic version of meningioma as an atypical type of the tumor has been rarely described in the literatures. Recurrent secondary meningioma invaded to pre-orbital soft and hard tissues can be found in extremely rare cases. We described a case of atypical invasive meningioma invaded to deep orbital soft tissue due to recurrence of the primary tumor previously treated by surgical removing and chemoradiotherapy. In this case, invasion to orbit, paranasal sinuses and masticator, infratemporal and buccal spaces leading to destruction of adjacent bony structures and mass engulfing the right globe resulting in considerable proptosis was the prominent feature.

Published: May 2023

There is a great demand for universities to foster critical thinking skills and this requires universities to develop effective assessment methods. Critical thinking skills enable students to interpret and integrate new information and the manner in which it is applied in unfamiliar settings. The purpose of this article is to determine the extent to which technology lecturers set summative questions that stimulate students to apply critical thinking skills. Facione’s framework for critical thinking skills was used to assess how technology lecturers stimulate critical thinking during the summative assessment. A qualitative approach was applied using a case study design. The sample constituted four technology lecturers who taught four technology modules at the undergraduate level. The findings indicated that technology lecturers in the selected university, to some extent, elicited critical thinking skills, which is important as modern education requires students to develop critical thinking skills to find technological solutions to everyday problems.

DIGITALIZATION IN AIRCRAFT MAINTENANCE PROCESSES
Authors: Alomar Iyad , Yatskiv Irina
Published: May 2023

Aircraft maintenance is considered as one of the major expenditures of aircraft operating costs. Notwithstanding that the new aircrafts, engines, and aircraft hard time parts became more durable and maintainable, the maintenance cost is still too high as against other costs like fuel and operational crews. Moreover, aircraft maintenance should be carried out with a high level of safety and security standards. All aircraft maintenance operations are subject to regulations by regulatory authorities. Such authorities can be attributed to European Union Aviation Safety Agency (EASA), Federal Aviation Administration (FAA) and National Civil Aviation Authorities (NAA). The last two decades have become a turning point in the transition from the paper form of the introduction of accounting for aircraft maintenance technical operations into electronic systems, despite all the difficulties associated with these procedures. Such difficulties are not limited to regulatory authorities, personnel training and investment which is case-sensitive for small companies. Similar to all other sectors of logistics and transportation, digitalization can be one of the key engines of change in aviation, especially in the aviation maintenance; thus, the study of digitalization effects on aircraft maintenance processes at present is an important factor for improving the maintenance processes and reducing the cost of aircraft maintenance. The objective of this research is to define the ability of aircraft maintenance and repair organizations to transform their processes. To that end, a data collection method in the form of a survey was implemented within Maintenance, Repair and Overhaul Organizations (MRO) and among aircraft maintenance engineers. The survey results demonstrate that the aircraft maintenance industry is not yet fully prepared for moving into digitalization in aircraft maintenance processes. However, at the same time, the study indicates the readiness of the personnel involved in the industry to improve themselves and their skills. The industry should invest in the improvement of safety and quality of tasks subject to digitalization by means of development of reliable software/hardware, and provide suitable training for safety and quality personnel.

Remote sensing (RS) and geographic information systems (GIS) have been used to guide the selection of suitable areas for aquaculture. This systematic review synthesizes the key suitability factors and constraints reported in the literature for establishing inland pond aquaculture. We searched for primary studies on Scopus and Web of Science according to preferred reporting items for systemic reviews and meta-analysis (PRISMA) guidelines. Between 1991 and 2020, 354 articles were published in 104 academic journals. The maximum annual number of publications occurred in 2020, with 22 publications, and there is an increasing trend in studies published over the past 30 years. From 12 selected studies, we identified 48 suitability factors, 11 related to soil suitability, 19 to socioeconomic and infrastructure suitability, and 18 to water quality and availability. The most frequently used suitability factors were road proximity, local market center distance, soil texture, soil slope, and water temperature. We listed 15 constraints that restrict or limit the selection of specific geographic locations for inland aquaculture. Urbanized areas, roads, and forests were the most frequently restricted areas. Geotechnologies provide powerful tools for spatial planning and management of aquaculture. Availability, quality, and access to spatial data are critical for the use of geotechnologies in the process of aquaculture site selection.

BACKGROUND: One-third of pregnant women will experience worsening asthma requiring emergency hospitalization. However, no report comprehensively discussed the management of asthma attacks in pregnant women in impoverished settings. We attempt to illuminate what general practitioners can do to stabilize and improve the outcome of severe acute asthma exacerbations in primary care with resource limitations. CASE REPORT: A nulliparous 29-year-old woman in her 21st week of pregnancy presented severe acute asthma exacerbation in moderate persistent asthma with uncontrolled asthma status along with gestational hypertension, uncompensated metabolic acidosis with a high anion gap, anemia, respiratory infection, and asymptomatic bacteriuria, all of which influenced her exacerbations. This patient was admitted to our resource-limited subdistrict hospital in Indonesia during the COVID-19 pandemic for optimal stabilization. Crystalloid infusions, oxygen supplementation, nebulized beta-agonist with anticholinergic agents, inhaled corticosteroids, intravenous methylprednisolone, broad-spectrum antibiotics, subcutaneous terbutaline, mucolytics, magnesium sulphate, oral antihypertensives, and continuous positive airway pressure were used to treat her life-threatening asthma. After she was stabilized, we referred the patient to a higher-level hospital with more advanced pulmonary management under the supervision of a multidisciplinary team to anticipate the worst scenario of pregnancy termination. CONCLUSION: Limitations in primary care, including the lack of sophisticated intensive care units and laboratory panels, may complicate challenges in managing severe acute asthma exacerbation during pregnancy. To enhance maternal-fetal outcomes, all multidisciplinary team members should be well-informed about key asthma management strategies during pregnancy using evidence-based guidelines regarding the drug, rationale, and safety profile.

Coronavirus disease is a serious viral infection that is characterized by severe inflammation and lymphopenia. The virus attacks many organs causing acute respiratory distress and malfunctioning of the organs leading to death. Through strengthening of the innate immune system, a balanced diet plays a critical role in defense against bacterial and viral diseases. A healthy diet before, during and after an infection can lessen the severity of the symptoms and speed up the recovery of damaged cells. Due to the Mediterranean diet’s high concentration of bioactive polyphenols, which have antioxidant, anti-inflammatory, and antithrombic properties, numerous studies have suggested that it is a preventative dietary strategy against many diseases including coronavirus disease. Nutrition and herbal plants play a key role to enhance the immunity of people to protect and fight against coronavirus. Diet rich in antioxidants and phytochemicals represents perfect barrier to the virus through elevation of the innate immunity of the body. In addition, gut microbiota including prebiotics, probiotics, and synbiotics were found to enhance immunity to reduce the symptoms of the disease during infection. Protein-rich foods and honey bee products reported significant role during and post-coronavirus infection. This review presents updated information from original pre-clinical and clinical researches, and review articles as well to expose the nutritive strategies including breastfeeding benefits to infants pre-infection, during, and post-infection with coronavirus.

Published: May 2023

Cet article présente un nouvel arbitrage entre efficience et équité consécutivement aux déductions d’impôt sur les dons privés pour un bien public, lorsqu’il y a plusieurs biens publics. La déduction d’impôt permet de lever efficacement des fonds publics mais elle peut aussi altérer la part relative des biens publics. Nous déterminons la condition pour qu’une déduction plus généreuse soit efficiente au sens de Pareto, condition pour que l’arbitrage disparaisse. Enfin, nous établissons la formule qui fixe le taux de déduction d’impôt optimal . Classification JEL  : H21, H23, H41.
