Authors: Malinowski Mariusz
Published: August 2023

Lokalne władze samorządowe odpowiedzialne są z jednej strony za prowadzenie racjonalnej polityki gospodarowania finansami, z drugiej zaś zobligowane są do realizowania działań prorozwojowych przyczyniających się m.in. do podnoszenia poziomu życia mieszkańców. Celem badań była identyfikacja wielowymiarowych zależności między kondycją finansową gmin wiejskich w Polsce a poziomem życia ich mieszkańców. W pierwszej części artykułu przybliżono pojęcie poziomu życia i kondycji finansowej JST. W drugiej części omówiono wybrane wyniki badań ankietowych przeprowadzonych wśród przewodniczących i wiceprzewodniczących rad gmin w styczniu i lutym 2022 r. W ramach realizowanych badań zastosowano analizę kanoniczną, a w jej zakresie zidentyfikowano cztery istotne statystycznie zmienne kanoniczne. Wartość największej i najbardziej istotnej statystycznie korelacji kanonicznej wyniosła blisko 0,90, a dla ostatniej istotnej statystycznie zmiennej kanonicznej wartość ta była równa ponad 0,75.
Z badań nad łańcuchówkami w dawnym księstwie muszyńskim
Authors: Cepil Monika
Published: August 2023

W artykule przedstawiono wyniki badań na temat wyglądu przestrzennego wsi o układach łańcuchowych na terenie dawnego księstwa muszyńskiego. Powodem podjęcia tematu była chęć ukazania, jak niegdyś wyglądały układy przestrzenne wsi w księstwie muszyńskim. Zagadnienie to jest ważne dla regionalistów i historyków zajmujących się badaniami tego regionu. Przeprowadzone badania mogą być również przydatne dla służb konserwatorskich, urzędników, planistów oraz wszystkich osób interesujących się osadnictwem wiejskim. Celem pracy była identyfikacja łańcuchówek w księstwie muszyńskim oraz ich charakterystyka pod względem kształtu siedliska i rozłogów oraz rozmieszczenia obiektów sakralnych. Analiza objęła wszystkie wsie leżące w tym regionie. W jej toku wykazano pewne charakterystyczne cechy badanych układów łańcuchowych, wszystkie bowiem cechowało siedlisko wytyczone w sposób jedno- lub dwustronnie zabudowany. Rozłogi zaś przybierały formę zwartych kompleksów z dominacją zespołów parcel długowąskopasmowych. W badaniu wskazano również prawidłowości przestrzenne lokalizacji kościoła lub cerkwi w łańcuchówkach: pośrodku wsi przy głównej drodze w granicy siedliska, w środkowym punkcie wsi, w dalszej odległości od drogi (za zabudowaniami) bądź w obrębie rozłogów. Cmentarz mieścił się przy kościele lub cerkwi albo w obrębie rozłogów wiejskich (za siedliskiem).

Published: August 2023

Agriculture has been present for many years; it has a long history and continues to be a major source of income and food to this day. However, the production process of the plant is difficult for people who do not have much experience in gardening. Therefore, this project aims to facilitate the cultivation process for home gardeners as a practical and easy-to-use solution. Soil moisture, air temperature, humidity, and soil salinity readings are used by the system to adjust the tomato’s environment. The system should monitor the tomato’s condition through sensors and make amendments to preserve those conditions, as well as detect tomato diseases through a deep learning model and cure them with the system if possible. All this will be facilitated by a mobile application. To implement the project, the following methods will be utilized: an SDI as the irrigation method, Wi-Fi as the type of communication, TensorFlow as the deep learning framework with transfer learning, and flutter for the app development.

Authors: Tebeta R.T. , Madyira D.M. , Fattahi A.M. , Ngwangwa H.M.
Published: August 2023

Designing and developing a new material can be challenging due to several aspects that require consideration. Materia behavior, material properties (physical or chemical), and other material characteristics are the factors to consider when developing new materials. In this work, polymer-based nanocomposite material is developed using High-Density Polyethylene (HDPE) as a matrix, Single-walled Carbon Nanotube (SWCNTs) as the reinforcing particles. Moreover, the mechanical properties of the produced HDPE/SWCNT nanocomposites, such as elastic modulus, were investigated at different weight fractions of SWCNTs. The investigation was conducted using numerical (Molecular Dynamics MD), theoretical (Finite Element Method FEM), and experimental approaches. The major aim of this study was to validate the accuracy of the developed MD model and the theoretical FEM with the experimental results. The obtained elastic modulus results from the MD and FEM were compared to see which method produced the results correlating with the experimental results. The compared results showed that MD results were consistent with the experimental results, even though they are not accurate, though the model can be improved. However, the FEM results do not correlate with the experimental results, hence the FEM model developed is not better for the prediction of the elastic modulus of HDPE/SWCNTs nanocomposites.
Simplified equations for natural frequencies of pipes on elastic foundation conveying gases
Authors: Attia Saher , Mohareb Magdi , Martens Michael , Adeeb Samer
Published: August 2023

Pipelines are commonly subjected to harmonic forces induced by reciprocating centrifugal pumps and compressors, unbalanced moments and forces in turbomachinery, pressure surge, and momentum changes due to valve operation. To guard resonance and fatigue failure, the natural frequencies of pipelines need to be accurately characterized. The present study introduces two sets of simplified equations to compute the natural frequencies of pipes conveying gases resting on uniform elastic foundation for different boundary conditions. While the first set is analytically derived by solving the differential equation, the second set is obtained based on a decoupling approach. A finite element code is built to verify the results computed using both sets of equations and excellent agreement is obtained.
UAV’s enhanced data collection for heterogeneous wireless sensor networks
Authors: BARKA Kamel , GUEZOULI Lyamine , REZKI Assem
Published: August 2023

In this article, we propose a protocol called DataGA-DRF (a protocol for Data collection using a Genetic Algorithm through Dynamic Reference Points) that collects data from Heterogeneous wireless sensor networks. This protocol is based on DGA (Destination selection according to Genetic Algorithm) to control the movement of the UAV (Unmanned aerial vehicle) between dynamic reference points that virtually represent the sensor node deployment. The dynamics of these points ensure an even distribution of energy consumption among the sensors and also improve network performance. To determine the best points, DataGA-DRF uses a classification algorithm such as K-Means.

Published: August 2023

Towards energy saving and clean environment, solar energy, as one of renewable energy resources, was found to be a suitable solution for generating power in many countries. Nowadays, solar chimney is considered a promising technology falling under the umbrella of solar energy systems for the purpose of generating electricity. In this study, a theoretical investigation into the design of collector and chimney besides the influences of some operating parameters, would be addressed for one solar chimney power plant (SCPP). This investigation mainly focuses on making thermal and dimensional analyses aiming particularly at improving SCPP performance. The theoretical findings were compared with real-world experimental results of Manzanares SCPP existing in Spain. The obtained results have shown a good agreement compared with experimental ones, which give a theoretical basis for effective design of SCPP. This work introduces a design roadmap for one solar chimney under given geometrical and operating parameters.

Published: August 2023

Signal identification is a critical topic in new communication systems, especially for cognitive radio to have an optimal sharing of radio resources. Some existing techniques, used to identify and classify wireless communication signals, show strong performance, but their sensitivity to noise levels or high computational complexity pose challenges. In this paper, we propose to use a Deep Learning technique, based on Residual Neural Networks (ResNet) to detect and classify V2X (vehicle-to-everything) signals. Three V2X communication technologies are studied and evaluated: ITS-G5, 4G, and 5G. The proposed model offers robust performance compared to a classical CNN-1D model even for the low SNR value.
Advanced Modelling of ATF Chromium-Coated Zr- Based Cladding High Temperature Oxidation
Authors: Vasiliev Alexander
Published: August 2023

Currently, the use of special low-corrosion coatings on nuclear reactors claddings made of zirconiumbased alloys is considered as one of encouraging ways to strengthen the reliability and performance of nuclear fission generation. This milestone direction of development is an evolutional way in nuclear power plants (NPPs) development. The chromium seems to be one of the best materials for protective coating. The chromium has excellent characteristics of corrosion and oxidation resistance compared to zirconium both for the NPP normal operation temperatures and high-temperature conditions. It is very important for the nuclear safety including the resistance to beyond-design-basis and design-basis accidents at NPPs. However, recent experimental data showed that in the temperature range close to upper limit of designbasis accident (1200°C) and higher there is a considerable worsening of Zr/Cr cladding protective properties. In particular, a role of Cr-Zr interdiffusion with subsequent influence on degradation of protective properties is revealed. In this paper, the new advanced model of high-temperature oxidation of Zr/Cr cladding is developed based on simultaneous solution of oxygen and zirconium diffusion equations in different layers of the cladding. In particular, a very important role of Zr outward diffusion to the interface between chromium oxide and metallic chromium resulting to severe degradation of protective properties is discovered recently. This phenomenon is taken into account in the model. The model is implemented to newly developed numerical module. The predictions of the model are compared with some experimental results on Zr/Cr claddings high-temperature oxidation available in the literature. The comparison shows that the basic phenomena are modeled with reasonable accuracy.
Harnessing new clean energy induced by electromagnetic resonance
Authors: Ide Osamu
Published: August 2023

We have no reliable new clean energy source for our future. The author has been researching new clean energy since 1973. Recently, the one author found was the method of electromagnetic resonance getting more energy than the input energy. While making an experiment of electromagnetic resonance between two coils, the author found an interesting phenomenon. The author supposed much electrical energy was induced more than the input energy by the resonance coils. The total energy of the coils was amplified more than the input electrical energy. The author started to compose an inverter of applying electromagnetic resonance. As the result, the output power from the transformer system with a resonance coil is larger than the input power. It means the inverter applying electromagnetic resonance will become a generator of no input energy by feedback of the part of the output power to the input terminal. It will be a generator of no natural energy resources.

Authors: Farid Ali Moltajaei , Mouhoub Malek
Published: August 2023

Many real-life applications rely on nanobot systems. These systems often imitate very simple tiny insects that can accomplish complex tasks. A swarm of nanobots can enhance the quality of life with the initial detection of diseases and treats patients with non-invasive surgeries. Since nanobots have highly controversial specifications due to quantum theory, this paper focuses only on innovative ideas as a future horizon. We define a list of objectives for coronary artery bypass. In this context, the swarm of nanobots reaches the limited flow artery and collaborates to remove the plaque. In addition, an online medical check-out system is stated in which swarm nanobots can be applied for initial disease detection. Finally, some ideas regarding medical check-out without visiting medical doctors and cancer treatments using this technology are discussed.

A Fluid Chemical Study of the World-Class, Intrusion-Related Archean Windfall Gold Deposit, Quebec, Canada
Authors: Choquette Brandon , Kontak Daniel J. , Côté-Lavoie Édouard , Fayek Mostafa
Published: August 2023

Windfall is a world-class Archean intrusion-related Au deposit (7.4+ Moz of Au) located in the underexplored Urban-Barry greenstone belt (Quebec, Canada). The deposit remains an enigmatic Au setting—its intrusion-related features contrast with the more common orogenic deposit type in the Au-endowed Abitibi greenstone belt. Mineralization consists of quartz-pyrite-carbonate ± tourmaline veins and stockworks that cut sericite-pyrite ± silica ± tourmaline ± fuchsite replacement zones, all of which overprint a swarm of 2697.6 ± 2.6 Ma quartz-feldspar porphyry dikes. That the ore zones and quartz-feldspar porphyry dikes are cut by a later set of 2697.6 ± 0.4 Ma quartz-feldspar porphyry dikes constrains mineralization temporally and spatially to intrusive activity. To further address the deposit genesis, ore petrology integrated with scanning electron microscopy-energy dispersive spectrometry analysis and cathodoluminescence imaging, laser ablation-inductively coupled plasma-mass spectrometry mapping of pyrite, fluid inclusion studies, and in situ secondary ion mass spectrometry isotopic studies (O, S) were completed. Ore-related sulfides are dominated by pyrite with lesser arsenopyrite, sphalerite, chalcopyrite, tennantite-tetrahedrite, galena, gold, electrum, and minor Sb-rich and telluride alloys. Four pyrite generations (Py1-Py4) occur, with elemental maps indicating primary Au is related to As-rich Py2 that is also enriched in Ag-Sb-Hg-Cu-Zn-Pb-Bi-Te. The δ34Spyrite values are similar for Py1 to Py3, with an inferred δ34Sfluid of ~5‰ consistent with a magmatic reservoir, whereas δ18Oquartz for both igneous (avg = 8.4‰, n = 28) and vein (5.7–14.6‰, n = 53) material suggests mixing of a magmatic fluid with an 18O-poor reservoir. Fluid inclusion studies from pre- to postmineralization veins indicate the predominance of a carbonic (±CH4) fluid, with rare aqueous-carbonic (CO2 = 5–98 mol %) and variably saline aqueous types. Whereas the data are considered to best reflect an intrusion-related deposit model, we note that some data, such as the carbonic-rich nature of fluid inclusions and large range in δ18Oquartz, are equivocal in regard to their meaning, and thus further studies are needed to resolve some aspects of this ore system.

Objetivo. Estimar y analizar dos modelos de volatilidad multivariada para precios internacionales de estos productos. Materiales y métodos. Los datos empleados provienen del Banco Mundial, con periodicidad mensual, de enero de 2001 a diciembre de 2022. Se emplea la causalidad de Granger y se estima un modelo de vectores autorregresivos (VAR) para rendimientos de precios; cuyos residuos son empleados para estimar dos modelos GARCH multivariados, tales como el VECH y el BEKK diagonales. Resultados. El precio internacional del maíz amarillo causa la formación de precios internacionales de la urea y del petróleo WTI. El mercado más volátil es el de la urea, seguido del maíz y en menor medida el del petróleo WTI. Los contagios de volatilidad de precios son más altos entre los mercados de maíz y la urea; seguido de la urea y el petróleo; mientras que los mercados de petróleo WTI y maíz son los menos contagiosos. Conclusión. Por su alta dependencia de estos bienes, México no sólo resulta afectado por presiones inflacionarias por las importaciones de los productos estudiados, sino también por el contagio de volatilidad o riesgo de mercados.
Examination of the Lawmaking Power of the Executive Arm of Government, Separation of Powers, Checks and Balances under the Nigerian Constitutional Democracy
Authors: Esu Effiong A.
Published: August 2023

Modern day government is designed to reduce concentration of power, promote personal liberty and prevent abuse of power. Many Constitutions are therefore crafted to provide for distribution of governmental powers, separation of powers, checks and balances. This is a notable feature of the 1999 Constitution of Nigeria which has prescribed the scope and limits for each arm of government, and areas to integrate the dispersed power into a workable government. Recently, the Supreme Court of Nigeria in Attorney-General of Abia State & 35 ors v. Attorney General of the Federation nullified Executive Order 10 issued by the President of the Federal Republic of Nigeria which sought to grant financial autonomy to the state judiciary and legislature. The judgment of the apex Court has raised a number of constitutional issues which are germane to our constitutional democracy. It has brought to the fore the need for each organ to be independent within its own domain and no one organ of government has supervisory power or control over other arms. It espoused the sanctity of the doctrine of separation of powers, checks and balances as desirable under the Nigerian Presidential Constitution. The confusion associated with the advent of executive orders requires urgent clarification not only for the citizens but the operators of the constitution. This paper adopts the doctrinal research methodology and critically analyzes the constitutional provisions on the law-making power of the executive arm, separation of powers, and draws experiences from advanced constitutional democracies. It concludes that the 1999 constitution recognizes some level of integration and interaction amongst the different arms of government, and maintains a delicate balance to avoid concentration of power. It is therefore the responsibility of each arm of government to operate within its area of competence and respect the limit prescribed by the constitution.
Environmental Dimensions for Pune Metropolitan Area
Some Systemic Considerations
Authors: Kanhere G. K.
Published: August 2023

Pune is a major metropolitan city in western Maharashtra, India. It has experienced rapid industrial growth, which has put pressure on the environment. Traditional urban planning in Pune, called the chowk system, involved the use of introverted houses with courtyards that provided light, air circulation, and plant life. These courtyards also served as spaces for disposing of garbage, which was used as manure for orchards. The British introduced the compact house in cantonments, which lacked courtyards but had external open spaces. Building bye-laws were also changed to reflect western planning practices, which have not been suitable for Indian conditions. As a result, Pune has experienced urban congestion, increased traffic, industrial pollution, and strain on urban services, leading to urban degradation. The city has implemented various measures to address these issues, such as traffic management schemes and pollution control measures.

The passage also discusses the nesting behavior and habits of these owls, including their preferred nesting sites and the frequency with which they breed. The author also notes that juvenile owls are often injured or killed by crows and that they can be found in injured or shocked states, sometimes requiring intervention to survive. The passage also mentions the importance of preserving these owl species and the need for more research on their populations and habitats.
Clonal Propagation of Teak (Tectona grandis) by compositive treatment of Auxin with Thaimine
Authors: Singh Sanjay , Kumar Pramod , Ansari S.
Published: August 2023

A pilot study was conducted in order to evaluate efficacy and economy of large-scale production of clonal plantlets of Teak. Semi-hardwood shoot cuttings taken from vegetative multiplication garden were treated with low doses of composite auxins (IAA, IBA and NAA) in combination with thiamine. Strong synergistic interaction between thiamine and auxins was observed for adventitious rhizogenesis, as the resultant increment in adventitious rhizogenesis due to combined auxin and thiamine application was several folds greater than from the independent application of auxins and thiamine alone. Treatment of 1200/800 ppm thiamine with a combined dose of auxins (250 ppm IBA, 125 ppm IAA and 125 ppm NAA) proved to be the most effective for rooting with increment of 4.85 and 4.79 times, respectively over the control. These treatments have been recommended for production of clonal planting stock of Teak on mass scale in open non-misting conditions.

Published: August 2023

This research delves into the innovative fermentation of wines using blue-green algae (spirulina), pineapple, and longan fruit. Traditional wine consumption, often synonymous with alcohol content, has seen a shift in value and health appeal with the infusion of spirulina. The fermentation process was monitored using both single and mixed cultures of Saccharomyces cerevisiae until it achieved 12% alcohol content. Sensory evaluations by fruit wine consumers revealed gender-based preferences in the acceptability of tangerine wine formulations. Specifically, females showed a higher liking for 5 out of 9 wine formulas, with sugar and acidity playing pivotal roles in flavours preference. Three distinct algae wine recipes were fermented at room temperature, with chemical analyses post-fermentation indicating standard pH levels for wine (3.0 - 4.0). Among them, the seaweed-pineapple blend was the standout, with a pH of 3.55 and a 72.96% approval rate among taste testers. The economic analysis highlighted the pineapple-seaweed variant's high production cost, though pure spirulina wine boasted the most significant return on investment. In conclusion, pineapple-infused spirulina wine emerges as a frontrunner in terms of taste, standard adherence, and economic viability, presenting a solution to the regional fruit surplus.

Published: August 2023

This paper proposes a synchronous sliding mode control (SSMC) method for a 4-DOF parallel robot model in practice with the influence of uncertain dynamics such as friction, external noise, and model error. A closed kinematic chain structure characterizes the parallel robot. The moving platform is controlled by four kinematic chains working together to follow a predetermined trajectory. However, traditional control methods only control each joint individually; if one of the actuators fails or has an external force, it can lead to system breakdown. Therefore, synchronous control to coordinate the operation of the arms is necessary. The synchronization algorithm is characterized by the cross-coupling error, which is the combination of tracking and synchronization errors for the system to achieve the synchronization goal. Cross-coupling error is used to design the sliding surface of the SSMC. The advantages of sliding mode control (SMC) are that it resists the influence of uncertain dynamics and it is combined with the synchronization algorithm. A control law is developed based on the sliding surface to ensure simultaneous convergence of both tracking and synchronization errors towards zero. The stability of the system is proven using the Lyapunov theory. In order to verify the effectiveness of the proposed approach, a 4-DOF parallel robot testbench is constructed. The SSMC controller results are compared with the testbench’s proportional-integral-derivative (PID), synchronous proportional-integral-derivative (SPID), and SMC controllers.

Published: August 2023

The present paper introduces a load shedding methodology that leverages an upgraded neural network that relies on the Cuckoo search (CS) optimization algorithm to compare the efficiency and applicability with other methods in terms of speed and feasibility. The proposed method will be tested on the IEEE-37 bus system. The results of the method are compared with other optimization methods. Thereby, this method gives good results and feasibility in application. The criteria of voltage are considered, specifically the sensitivity index dV/dQ is proposed to find weak buses in the system that need to be relieved of the active power burden. Then, the shedding priority bus ranking is created to ensure the most favorable load shedding plan for the system to maintain voltage stability. Besides, the frequency parameter is also considered to calculate the optimal amount of shed load. The model system was tested by using POWERWORLD software. After comparing the results with other methods outlined in the paper, it has been determined that the proposed approach is highly effective for optimizing grid shedding in the system.

Authors: Tran Thanh Tai , Pham Vu Minh Hoang
Published: August 2023

Geopolymer has emerged as the potential alternative to Portland cement in recent years. In addition, fly ash and recycled glass are abundant by-products derived from the industry. The purpose of this study was to evaluate the potential of using recycled glass to replace the sand aggregate in slag-blended fly ash-based geopolymer mortar. For geopolymer synthesis, the mixture of water glass (Na2SiO3) and sodium hydroxide (NaOH) solution with a NaOH concentration of 14 mol/l was used as an activator. In the mortar mixture, the recycled glass's investigated replacement level of the sand aggregate was up to 100 %. Using recycled glass (RG) as fine aggregate was seen to increase the mechanical strength compressive strength and flexural strength of mortar after 28 days of curing. Otherwise, there was a reduction in the drying shrinkage of mortar samples with a high recycled glass content of 80 and 100 %.

A Study on Motivation of Second-year Students Enrolling in Math-through-English Teacher Training at a University in Vietnam
Authors: Tran Thi My Linh
Published: August 2023

This study aimed to examine the motivation of 31 sophomores taking the Math-through-English teacher preparation program at the Faculty of Mathematics, Hanoi National University of Education. The study's use of quantitative and qualitative methods revealed that the second-year students were mostly intrinsically driven and had a modest level of motivation to complete this integrated course. This contributed to affirming that teaching science subjects in English was somewhat essential and influenced students' learning and career orientation. The three most common motivators were the lecturers, the voluntary aspect of MTE learning, and the pleasant relationships with classmates. Given the study's findings, various suggestions are made to improve the course's efficacy in particular and the use of teaching sciences through English in Vietnam generally.

Durante mucho tiempo, las guerras se han entendido como hechos de armas que ocurren en campos de batalla. No obstante, los modos de concebir y hacer la guerra se modificaron como respuesta a las claves que provenían tanto de los cambios en la organización política como de los de las tecnologías. No solo cambiaron la estética de la guerra, la capacidad letal de los atacantes, los sentidos de la intervención, las herramientas a ser empleadas, las tecnologías, los estilos y los modos, sino también sus protagonistas, los desafíos y su propia concepción. El nuevo milenio inició su despliegue con modalidades de entender y hacer la guerra muy distintas a las heredadas de las experiencias pasadas y que modifican sustancialmente su concepción y sus prácticas.
