Probability of simultaneous multiple leakages at sections of water networks in the process of localization of hidden water leaks
Authors:   Lviv Polytechnic National University, Department of Hydraulic and Water Engineering, Zhuk Volodymyr , Bodnar Taras ,   Lviv Polytechnic National University, Department of Hydraulic and Water Engineering
Published: May 2023

Hidden leaks from water supply networks account for 50% to 90% of total leakage losses. The presence of two or more simultaneous leaks in a section of the water supply network significantly reduces the accuracy of locating hidden leaks. The method of independent Poisson events and the hypothesis of stationarity, absence of consequences, and ordinariness of leaks are used for the probabilistic description of the problem of multi-leakage in water supply networks. The analytical dependence of the probability of multiple leakages on the specific annual emergency rate of the site, its length and the duration of the localization and repair period is obtained. A generalized semi-empirical equation was obtained for estimating the maximum permissible duration of the localization and repair period depending on the annual emergency rate of the site for a given multi-leakage probability.

Published: May 2023

The sustainability of the concrete industry is in jeopardy due to the use of natural resources which impacts the environment. A swift shift towards sustainable thinking is required considering the emergency triggered by human activity on the climate. Glass concrete (GC) has sparked curiosity of the construction industry owing to its environmentally friendly approach. This article examines the environmental implications of partially replacing natural aggregates in concrete with recycled glass aggregate at various percentages i.e. 10%, 25%, 50%, and 75% which is then compared to controlled concrete specimen (CC). The assessment indicated 287 kgCO2Eq were generated for control concrete (CC), whereas concrete with 20% glass aggregate (GA) resulted in 258 kgCO2Eq. global warming potential. Likewise, M25 concrete was reported to have 1.68 kgCFC-11Eq compared to 1.85 kgCFC-11Eq for natural aggregate concrete. Even though glass concrete demonstrates lower values in several environmental effects, there is need for improvement in impact categories including acidification and respiratory organics.

The main purpose of this research is to analyze the impact of changes in coal prices. Scholars insinuated that the extensive capital requirements of building thermal power stations and coal mines lead to power production costs parachuting beyond the reach of many economic players. These rising costs in coal prices and power production costs, the retail price of electricity has not been adjusted, resulting in many players in this industry incurring losses. This study will use Statistical multiple regression and correlation analysis to test the relationship between two variables, coal price changes being an independent variable and changes in the price of electricity being the dependent variable. The findings show a strong dependence between changes in coal prices and electricity pricing in South Africa. People scrambling to coal mining is a concern since no proper regulations lead to land degradation. Moreover, since NERSA regulates electricity prices, miners are forced to use cheaper methods of extracting coal to keep the costs low.

Published: May 2023

With high youth unemployment rates in South Africa, strategies to increase youth entrepreneurship have become essential. Youth in rural communities tend to face circumstances which require proper examination to establish how they can be motivated to engage in entrepreneurship. The purpose of this study is to explore the question: How do community and family factors in a rural context influence youth to engage in entrepreneurship? To address this research question, a case study research design was adopted, and data were collected through focus group discussions with youth entrepreneurs in a rural township community. The fifteen-member focus group discussion provided evidence that youths in rural contexts face unique challenges and scenarios that demand specific consideration. Essentially, it was established that the community and the families of the entrepreneurs provided the motivation to overcome circumstances and to achieve. Community elders and leaders were found to be critical in influencing the psyche and entrepreneurial behavior of the youths. Resources and entrepreneurial ideas and skills were also found to be passed from generation to generation through inheritance systems or through sharing. Rural communities were further found to be endowed with various resources whose exploitation was based on the collective culture in rural communities. Families were also found to be sources of number of entrepreneurial traits such as risk taking, desire for independence or the need to achieve. This study recommends that both public and private institutions in rural communities should promote the welfare of rural communities and families so that imperative entrepreneurial behavior emerges.

The petroleum wholesale sector plays a significant role in the value chain of South Africa. Although there has been strides by the South African government to provide an inclusive and enabling entrepreneurial ecosystem for emerging businesses, some industries have been affected and therefore lagging behind. The petroleum industry is a case in point and has been moving slowly toward achieving its ambitious transformation goals as committed in the Liquid Fuels Charter. This article seeks to analyse the factors affecting SMEs’ entrepreneurial growth. A qualitative approach followed, and the findings suggest that the power of the oil majors in the value chain and the apparent government support hinder SMEs’ ability to grow in the sector. The paper recommends that small businesses in an interdisciplinary programme gain skills from different industries, and therefore able to service various industries which will broaden their service and competencies.

The present research looked at the return to schooling (Public and Private schools) in the census region of the East South-Central Division of the United States. The demographic diversity of this region is the primary reason for its selection. The functional form of return to schooling on education has the specified wage as the long-linear function of school attendance (in years), controlling for gender, race, work experience, occupation status, and educational attainment. We followed the extant literature to control a few socioeconomic variables. The article used 2020 sample data from Integrated Public Use Microdata Series (IPUMS) to estimate the parameter coefficients. The findings show private schools yield a higher return in terms of subsequent wage earnings compared to private schools. The results highlight a higher differential between private schools & public schools for Caucasian Americans over African Americans. Similarly, the differential is higher among females over males

Published: May 2023

The study aimed to identify the level of efficiency of the Saudi capital market and the business sectors included in it during the Corona pandemic, with a comparison between these sectors. The daily indices values of the capital market and the business sectors included in it were relied upon during the pandemic period from 2020 to 2022. The indicators were described through the arithmetic mean, standard deviation, and a graphical display of the trend graph for each indicator. To test the efficiency of the capital market and the sectors included in it, the Jarque – Bera test was used to test the Normality, the Run test to test the random walk of the indices values, and Augmented Dickey Fuller test (ADF) to test the stationary of the indices values series during the study period. The most important results of the study were the inefficiency of the weak form of the Saudi capital market and the sectors included in it during the pandemic period. The study also found that the sectors most affected by the pandemic are the transportation sector, the construction sector, public utilities, the entertainment sector, and the retail sector for luxury goods. While the sectors least affected by the pandemic are the pharmaceutical sector, health care, food, energy, and the telecommunications sector. The most important recommendations were that the individual investor should be careful when investing financially in business sectors that work in the field of entertainment and luxury goods in periods of natural crises, and it is preferable to invest in basic goods and services sectors, and the Capital Market Authority should educate investors on how financial investment is made in light of crises , while achieving high transparency, and fully providing data to investors so that no unusual returns or losses are achieved.

Authors: Santos Renatha Michelly Sabino dos , Nascimento Raquel Ferreira do , Silva Lucas Caitano da , Carvalho Filho José Adson Andrade de , Paiva Anderson Luiz Ribeiro de
Published: May 2023

A escassez dos recursos hídricos aliada ao aumento nos níveis de contaminação tem sido alvo de preocupação por toda a comunidade. Recentemente, foram detectados novos compostos poluidores, em concentrações que variam entre ng.L-1 e µ.L-1, denominados de Contaminantes Emergentes (CEs). Essas substâncias são potencialmente prejudiciais ao meio ambiente e à saúde humana, e dificilmente são removidas pelos tratamentos convencionais de água e esgoto. Assim, o estudo objetivou elaborar uma revisão narrativa sobre as principais rotas de entrada dos CEs no ambiente aquático, os efeitos causados pela presença desses poluentes na água, e apresentar soluções de tratamento para a remoção desses contaminantes micropoluentes. Os CEs são introduzidos na água, sobretudo, por meio de fontes antropogênicas (lixiviados de aterros sanitários e esgotos domésticos e industriais) e estão associados à feminilização de animais, doenças neurológicas, reprodutivas e imunológicas, redução da diversidade de microinvertebrados nos rios e extinção de aves. Entre os métodos de tratamento, apresentam destaque na remoção dos CEs da água: o carvão ativado, filtração por membrana, filtração em margem, wetlands, lodos ativados, além dos processos oxidativos avançados. Cada uma dessas técnicas demonstra vantagens e desvantagens, sendo necessário um estudo mais acurado sobre as características do local a ser implantado o tratamento, a fim de determinar a mais adequada àquele ambiente.

Smartphone-Operated Smart Farm Watering System Using Long-Range Communication Technology
Authors: Mog Lee Kyung
Published: May 2023

Keeping proper soil moisture is essential in growing good quality and efficient fruit yield. To that effect, soil moisture level must be controlled, to maintain proper watering. A smartphone application was developed to operate a smart farm watering system. It monitors the soil’s moisture and launches sprayers to water dried areas. The system’s architecture was built in a distributed client-server computing system, in a small computing grid. The grid was built across long range (LoRa) communication networks with the same ID, but different addresses. In terms of integration, the system was built using autonomous microprocessors, which consist of a server and five client microprocessors. A smartphone was used as the server of a central controller, and four moisture detection modules and a water spraying system module were used as autonomous clients. The server was inter-connected with the clients via a star-type topology network in the polling processes. Each client module autonomously analyzes the measured digital voltage of the moisture sensor plugged into the soil. When the server sends queries regarding the status of the moisture level, the client sends the request signal to the server using the LoRa communication technology. The communication between the server and the clients is based on the LoRa communication technology. The LoRa-to-Bluetooth converter is used to connect the Bluetooth and the LoRa signal. The field test was performed in a watermelon field, with an area of approximately 6600 m2. The water spraying system constructed with LoRa communication technology could successfully manage and control the moisture level in the field test.

Published: May 2023

The paper proposes a stand that can be used for the testing of propellers and rotors with diameters up to 2.4 m, whose areas of application encompass, inter alia, vertical takeoff and landing (VTOL) type multi-rotor drone systems. The presented solution allows for testing propellers in systems with electric motors. To a certain extent, it is possible to achieve an increase in the measuring range by changing electric motors, power supply systems and measuring sensors. The paper presents several solutions for test stands that can be applied in the testing of propeller parameters, and commercially available propellers have also been deployed in the testing routines. The paper briefly presents the concept of the stand and its design, as well as the principle of operation and structural calculations underlying its functioning, after which the numerical model of the test stand is explained. The article then demonstrates the particular results of the test stand model’s functioning using the EMRAX 188 electric motor and two propellers, namely a commercial Aerobat propeller and a composite propeller designed and manufactured at the Łukasiewicz – Institute of Aviation. Thus, the paper presents both the theoretical results that follow from the model and the results of experimental research.

Protection of Foreign Investments in Türkiye under International Law: Alignments and Dissociations with International Tendencies
Authors: ERGENE Deniz
Published: May 2023

Protection of foreign investments under international law is treaty-based. Investment treaties are mostly bilateral, i.e. they are concluded between two states and provide the investors of each contracting party rights to a minimum standard of treatment in the territory of the other contracting party. Foreign investments in Türkiye, too, are protected by bilateral investment treaties. Türkiye has concluded a total of 132 bilateral investment treaties with 113 different states. As of today, 82 of these bilateral investment treaties are in force. We examined all bilateral investment treaties that Türkiye has been party to, including those that have not entered into force yet and those that have entered into force but that were subsequently terminated. We, thus, sought to determine how Türkiye established and developed its bilateral investment treaty network. In order to get a complete picture of the establishment and development of the Turkish network, we compared it with international tendencies of bilateral investment treaty network establishment programmes. As a result of this comparison, we determined that Türkiye’s bilateral investment treaty network mostly aligned with international tendencies, especially between 1960 and 2000. We observed that Türkiye behaved more like developing and transition economies in this time period; hence it first concluded investment treaties with investment exporting states. However, we remarked a dissociation from international tendencies in the 2010s. As a result of our examination of the Turkish bilateral investment treaty practice in the 2010s, we made the following findings: Türkiye did not align with the tendency to withdraw from the network of investment treaties, a tendency popular among developing and transition economies, and it mostly dissociated from the tendency to replace existing investment treaties with new generation treaties, a tendency pioneered by developed economies.

Published: May 2023

Neonatal necrotizing enterocolitis (NEC) is a syndrome characterized by inflammation and ischemic necrosis of the gastrointestinal tract that can course with variable clinical manifestations: such as abdominal distension, bilious vomiting, hematoquezia, frequent gastric waste, decreased hydro-air noises, fecal changes. The condition is usually associated with systemic signs (pallor, apnea, hypoactivity, dysthermias). NEC can manifest with partial intestinal necrosis and have complete recovery, requiring only clinical treatment. Case report: newborn (NB) of T.A.A., female, premature (33 weeks and 5 days), extremely low weight (888g), APGAR 8/9, referred to the Neonatal Intensive Care Unit (ICU NEO). On the 1st day of life, he presented significant abdominal Residência Pediátrica; 2023: Ahead of Print. DOI: 10.25060/residpediatr-2023-567 distension and bilious debt by the orogastric tube (SOG). It eliminated meconium after rectal stimulation, with 43 hours of life. He maintained abdominal distension until the 10th day of life, progressing, with progressive improvement (reduction of abdominal distension, change in the aspect of the debt by SOG), after the institution of adequate therapy. On the 11th day of life, he started a minimal enteral diet, progressing gradually, achieving success in diet progression. Enterocolitis is one of the most frequent gastrointestinal emergencies in neonates, most frequently affecting premature newborns, especially those born with very low birth weight. Studies indicate the recent increase in the incidence of NEC in NEO ICUs, in several countries, due to the increased survival of premature newborns. Therefore, there is a need for a greater dissemination of knowledge about the pathology; mainly among health professionals who work in these units.

La búsqueda de un mundo seguro es uno de los principales objetivos que la Organización de las Naciones Unidas (ONU) recogió en su Informe del Milenio. La máxima es el nuevo enfoque global que deben recibir las materias relacionadas con la seguridad, pues los retos enfrentados han cambiado, y la guerra, el terrorismo y la delincuencia hacen que el escenario atienda conflictos complejos y multidimensionales necesarios para responder a esos a nuevos desafíos. Por ello, en el presente artículo se analizará la situación actual con respecto a leyes de seguridad ciudadana, donde se enfatizará en la Ley de Protección Civil y la Ley de Seguridad Ciudadana. Se observarán las múltiples críticas que la Ley de Seguridad Ciudadana, sobre todo, ha recibido. Se propondrá una solución en forma de medidas que conformen una estrategia de intervención de respuesta rápida, que facilite al gobierno el bien último: la convivencia en las calles.

Este artículo pretende presentar estrategias, desde el enfoque pedagógico de las configuraciones didácticas, para la construcción y la trasmisión del conocimiento en la Escuela de Armas Combinadas del Ejército Nacional. Dichas configuraciones abren un espacio para transformar la pedagogía en la Fuerza. Esta investigación logra describir necesidades y desafíos que se convierten en imperativos de transformación pedagógica, cuya implementación fortalezca los procesos de conocimiento en el estamento militar. Con una metodología cualitativa de carácter exploratorio descriptivo, se presentan los hallazgos para determinar un anquilosamiento en la idea de transmisión de saberes de forma memorística con débil proyección del pensamiento crítico, la investigación y la elaboración de saberes. Adicional, una deficiente inserción en el uso de herramientas que brindan las tecnologías de la información en las estrategias didácticas.
Contrato de seguro, regulação e intervenção nas condições contratuais
Authors: Gonçalves de Lima Beltrão Irapuã
Published: May 2023

Este trabalho pretende abordar o reconhecimento das modificações ocorridas em alguns institutos jurídicos nos vínculos obrigacionais, notadamente nas relações de contratualização das relações privadas e, com especial ênfase, suas decorrências para os contratos de seguro e coberturas securitárias. A partir da crise do modelo clássico consagrado no Estado liberal e suas exportações para os negócios jurídicos, perquirimos o surgimento de um dirigismo contratual no século XX e a consequente mudança das condições de contratação em virtude dos processos de produção em massa, especialmente para abordar o tratamento regulatório nas diversas modalidades securitárias. A partir de tal fotografia verifica-se o campo para a atuação futura dos princípios da Lei de Liberdade Econômica.
Processos administrativos disciplinares: agilizar é preciso.

Published: May 2023

Este estudo navegou nas águas do direito administrativo, pelo seu ramal disciplinar, nos rios do Sistema Correcional do Poder Executivo Federal (SisCor). Investigou-se a celeridade processual, com o objetivo de encontrar formas de impulsionar a tramitação dos processos administrativos disciplinares (PAD’s). A pesquisa justificou-se pela atual preocupação do SisCor com o tempo de duração dos processos, que aflige todo o sistema processual brasileiro e a sociedade, pois a melhor justiça é aquela que não tarda. O método para alcançar o objetivo foi pesquisar no “Painel Correição em Dados” da CGU o tempo de tramitação dos PAD’s e, em seguida, na normatização e na doutrina da processualística disciplinar. Assim, tratou-se de pesquisa aplicada, descritiva, explicativa, quantitativa e qualitativa, com técnica de documentação indireta. Como conclusão emergiram dez medidas que agilizam a tramitação processual.
Simplified Real-Time Flush Air-Data Sensing System for Sharp-Nosed Hypersonic Vehicles

This paper discusses a flush air-data sensing (FADS) system for a sharp-nosed hypersonic vehicle designed to estimate flight air data in real time at hypersonic speeds. The design’s target condition is Mach 5.0 to 7.0 with an angle of attack within 5 deg. The FADS system estimates air data by relating them to surface pressures measured from surface-mounted ports on the vehicle forebody. Unique combinations of pressure ratios were used to estimate the freestream dynamic pressure, which was a primary parameter for the flight experiment, the angle of attack, and the Mach number. The proposed FADS estimation algorithm was validated through numerical simulation, which was also used to generate datasets of surface pressures for given flight conditions. To handle possible sensor errors related to estimation accuracy in real-time estimation for a flight experiment, redundant systems were implemented. The results indicated that the designed FADS system can estimate air data within the uncertainty of 4.8% for a single estimator by considering sensor errors for freestream dynamic pressures in the range of 0–100 kPa, including targeted and off-design flight conditions. The proposed algorithm can estimate the air data with an acceptable level of uncertainty while retaining the robustness of estimation to sensor failures with low computational cost.

The flowfield of a coaxial counter-rotating rotor in hover was measured using particle image velocimetry. The goal of the measurements was to investigate the flow features of coaxial rotors, including interaction between the rotors, and to measure inflow over the rotor radius and azimuth. The phase-resolved measurements were performed at several azimuthal index angles behind the rotor blades, with 500 instantaneous flow realizations per azimuth. Axial velocity profiles extracted from the phase-averaged flowfields exhibited the effect of bound circulation associated with blade passage, the trailed vortex sheet, and the effect of the blade tip vortex. Tip vortex characteristics were extracted from the measurements and were shown to compare well with semi-empirical models in most cases. The measured inflow was captured well by blade element momentum theory when the mutually induced velocities were accounted for. The lower rotor was found to behave more like an isolated single rotor, whereas tip vortices from the upper rotor convected faster radially inward and downstream than the lower rotor tip vortices. Upper and lower rotor tip vortices exhibited similar core radii ranging from 12 to 18% of the rotor blade chord, and they grew at a similar rate. However, this vortex growth rate was different from that of an isolated single rotor.
Analysis of Flight Plans for Visual Flight Rules Toward Preflight Information Sharing

With the increased use of small unmanned aircraft systems, the collision risk between manned aircraft and small unmanned aircraft systems is increasing. One promising solution to avoid such risks is preflight information sharing and conflict resolution between manned aircraft and small unmanned aircraft systems. However, detailed flight plan information is often not available for aircraft operating under visual flight rules. The authors developed flight estimation methods for a visual flight rules helicopter flight by using the information extracted from the visual flight rules flight plan, such as the origin/destination points, the estimated flight time, and the names of the points on the route. Furthermore, one method estimates the positional coordinate of points on the route by using the track data of the previous flights. The proposed methods were evaluated by comparing the results with the actual track, and they are discussed from the viewpoints of information quality and implementation effort. Potential implementation for future operational environment in a low-altitude airspace was investigated based on the evaluation results. Finally, recommendations are provided for preflight information sharing and conflict resolution between visual flight rules aircraft and small unmanned aircraft systems.
