Analysis of three-dimensional slope stability combined with rainfall and earthquake
Authors: Wang Jiao , Wang Zhangxing , Sun Guanhua , Luo Hongming
Published: November 2023

Abstract. In the current context of global climate change, geohazards such as earthquakes and extreme rainfall pose a serious threat to regional stability. We investigate a three-dimensional slope dynamic model under earthquake action, derive the calculation of seepage force and the normal stress expression of slip surface under seepage and earthquake, and propose a rigorous overall analysis method to solve the safety factor of slopes subjected to combined with rainfall and earthquake. The accuracy and reliability of the method is verified by two classical examples. Finally, the effects of soil permeability coefficient, porosity and saturation on slope stability under rainfall in a project located in the Three Gorges Reservoir Area are analyzed. The safety evolution of the slope combined with both rainfall and earthquake is also studied. The results indicate that porosity has a greater impact on the safety factor under rainfall conditions, while the influence of permeability coefficient and saturation is relatively small. With the increase of horizontal seismic coefficient, the safety factor of the slope decreases significantly. The influence of earthquake on slope stability is significantly greater than that of rainfall. The corresponding safety factor when the vertical seismic action is vertically downward is smaller than that when it is vertically upward. When considering both horizontal and vertical seismic effects, slope stability is lower.

Author experiences of researching, writing and marketing climate fiction
Authors: Cothren Alex , Matthews Amy , Hennessy Rachel
Published: November 2023

There is a growing body of literature that studies the emotional impact of engaging regularly with climate change in a professional capacity, with a particular focus on climate scientists and activists. However, the experience of climate fiction writers is yet to be investigated, despite the many years such writers must spend deeply focusing on the issue. This project fills this gap by interviewing 16 Australian and New Zealand writers of climate fiction, focusing on how the different stages of the publishing cycle – research, writing and marketing – affected their wellbeing. While there was a diversity of experiences, we have identified a number of trends. Despite some confronting moments, the research and writing phases represented a positive experience, with writers gaining a sense of control and purpose in the face of the immense climate change problem. For many writers, though, the post-publication phase produced more difficult emotions, including feelings of guilt over inaction in the face of the crisis, frustration at reader responses, and the pressure of being construed as climate change experts in interviews and at festival events.
Clelia Romano Pellicano: la hija feminista del Risorgimento italiano

A través de ellos se demuestra cómo la escritora parte de una observación directa de las mujeres trabajadoras con un posterior compromiso que la lleva a manifestarse abiertamente como mujer feminista.
L’espressione dell’epistemicità e dell’evidenzialità in siciliano. Gli avverbi in -ca
Authors: Cruschina Silvio
Published: November 2023

In questo contributo descriverò i mezzi presenti in siciliano per esprimere le categorie dell’epistemicità e dell’evidenzialità. Pur riconoscendo le differenze sul piano concettuale e teorico, mostrerò che il siciliano presenta lo stesso processo di formazione di elementi epistemici ed evidenziali, un processo che ha origine nella fusione di un elemento lessicale (un verbo o un aggettivo) con il complementatore -ca: dicica, parica, penzica e capacica. Dal punto di vista morfologico e sintattico questi elementi si comportano da avverbi; semanticamente, offrono chiari esempi di distinzioni modali e funzionali, a volte anche sottili (per es. in relazione ad una scala epistemica). Data la ridotta autonomia degli avverbi evidenziali ed epistemici del siciliano, il processo che ha portato alla loro formazione è da considerarsi come un processo di grammaticalizzazione. Un’analisi approfondita degli avverbi evidenziali ci porta inoltre a concludere che essi svolgono le stesse funzioni degli evidenziali grammaticali in altre lingue, rendendo pertanto irrilevante la distinzione tra espressioni lessicali ed espressioni grammaticali spesso sottolineata nel dominio dell’evidenzialità.
Sui marcatori modali siciliani formati con il complementatore ca
Authors: Restivo Maria Laura
Published: November 2023

Scopo del contributo è esaminare alcune forme del siciliano contemporaneo composte da verbo/aggettivo + complementatore, dicica, parica, penzica/penzuca e capacica (letteralmente ‘dice-che’, ‘pare-che’, ‘pensi-che’, ‘penso-che’, ‘capace-che’), classificate come avverbi in Cruschina e Remberger (2008) e Cruschina (2010, 2011, 2015); le prime due hanno valore evidenziale, le altre epistemico. Grande attenzione verrà riservata all’analisi del loro comportamento sintattico per stabilire se ca operi ancora come complementatore. Ai fini della nostra indagine verranno considerati non solo dati di scritto digitato (corpora itWaC e itTenTen16) e di parlato, ma anche i risultati di un questionario volto a raccogliere giudizi di accettabilità, somministrato ad un campione costruito tendendo conto delle principali variabili socio-demografiche. L’analisi dei dati consentirà di verificare se le forme dicica, parica, penzica/penzuca e capacica testimonino un processo di grammaticalizzazione e se sia possibile annoverarle tra gli avverbi.

Objective: This case study is to implement non-pharmacological therapy by administering melon fruit to reducing blood pressure in hypertensive patients.
Method: This study uses descriptive analysis with a case study approach. This case study is to describe, objectively describe, and explore in-depth data regarding nursing care for hypertensive patients with ineffective family management problems in the Health UPTD Work Area of the Cikoneng Health Center. When conducting research, the authors also make observations at certain times in the form of assessments, nursing diagnoses, interventions, implementation, and evaluation. Providing non-pharmacological therapy to eat melons to reduce high blood pressure and respondents' adherence to eating melons The observation began after being given health education, which aimed to find out whether there was adherence to eating melons and whether there was a change in blood pressure or no change. This study was conducted on Mrs. C with hypertension in Colendra Hamlet, RT.13 RW.05, Sindangsari Village, Cikoneng District, Ciamis Regency, in the working area of the UPTD Cikoneng Health Center from March 31 to April 3, 2023, for 4 days of visit.
Result Based on the results of an assessment of hypertensive family members and there were nursing diagnoses assigned to the family, namely ineffective family health management, related to the inability of the family to care for sick family members and the inability of the family to make the right decisions. Given the intervention and implementation of non-pharmacological therapy of melon fruit to reduce the patient's blood pressure. The implementation was given for 3 days, the patient's blood pressure gradually decreased from 160/100 MmHg to 150/90 MmHg, but had not yet reached normal levels. So that the action of giving melon fruit can be continued and applied in daily life independently.
Conclusion: Giving non-pharmacological therapy giving melon fruit has proven to be useful for lowering blood pressure in hypertensive patients, the benefits of therapy will be maximized if done regularly and gradually.

Authors:   Nancy S., Flier Michael S. , Kollmann Nancy S. , Rowland Daniel , Monahan Erika
Published: November 2023

The essays in this volume vary in content over time and space, forming a fitting tribute to Valerie Kivelson, the Arthur F. Thurnau Professor of History and Thomas N. Tentler Collegiate Professor at the University of Michigan. Michigan. Her scholarship has inspired the contributors to explore the center and edges of Muscovy and its Petrine emergence as the Russian Empire, how it imagined itself and how others imagined it. In recent years the study of empires has commanded considerable scholarly interest. The questions that have emerged from these recent approaches have become even more urgent as a result of Vladimir Putin’s unprovoked, all-out invasion of Ukraine in February of 2022,following eight years of illegal Russian occupation of Crimea and large portions of southeastern Ukraine. Scholars, journalists, politicians, and ordinary citizens in Russia, Ukraine, and the West have begun to reflect intensely on the nature of Muscovy and the Russian Empire that succeeded it to better appreciate the historical and cultural distortions generated in medieval and early modern Muscovy. An empire and its limits has, indeed, become one of the most pressing issues of our time.
Power Conversion Systems with Synchronous Control and Regulation on the Base of Powerful Diode-Clamped Inverters via Pulse Width Modulation
Authors: Oleschuk Valentin
Published: November 2023

This article provides a brief overview of the development and dissemination of the method of synchronous multi-zone pulse-width modulation (PWM) in relation to the regulation of diode-clamped inverters which are the main executive elements of the medium-power and high-power adjustable speed electric drives. It is shown that the modified schemes and algorithms of synchronous multi-zone PWM, applied for control of diode-clamped inverters, assure providing minimization of the common-mode voltage in systems, as well as continuous synchronization and symmetry of the base phase and linear voltages in drive systems on the base of diode-clamped inverters over the entire control range. There are no even harmonics and subharmonics in the spectra of the phase and line-to-line voltages of three-phase and six-phase drive systems, which helps to reduce losses in systems and increase the efficiency of their operation. As a result of a comparative analysis of the integral spectral characteristics of the main voltage waveforms of adjustable speed drives based on diode-clamped inverters, recommendations are formulated for the rational choice of schemes and algorithms of synchronous multi-zone PWM for the relevant systems and installations, depending on their operating modes.

DIPLOMATIC DEXTERITY: MONGOL QAGHANS OF THE YUAN DYNASTY AND THE QUEST FOR EAST ASIAN HEGEMONY
Authors:   Nevsehir Haci Bektas Veli University, ATIK Kubilay
Published: November 2023

This study examines the foreign policy and diplomacy pursued by the Mongol Khans during the Yuan Dynasty (1268-1369), who held the titles of both Mongol qaghan and Chinese Emperor. Specifically, Qubilai Qaghan, who received the title of Khan at a qurultai held in the city of Shangdu, located in present-day Beijing, rather than the Orkhon region traditionally used for convening qurultais, and without the participation of all Mongol nobles, had to establish his legitimacy throughout his life both among the Mongols and the people he conquered in Asia. For this purpose, he utilized diplomacy and foreign policy as much as conquests. Within the scope of this study, the rhetoric and legitimacy foundations used in diplomacy are examined, taking into account not only the Goryeo kingdom in Korea, which became a vassal of the Mongol Empire but also regional states such as Japan, which did not acknowledge Mongol superiority and dominion, as well as diplomacy conducted with states in Southeast Asia and Europe. During this period, the Yuan Dynasty successfully blended elements of legitimacy belonging to China with those from the Turkic-Mongol tradition in its foreign policy, thereby leaving a lasting diplomatic legacy, especially in East Asia.

Água e saneamento no Brasil: conflitos, apropriação e injustiça climática
Authors: Fracalanza Ana Paula , Da Paz Mariana Gutierres Arteiro , Alves Estela Macedo
Published: November 2023

Este artigo aborda os conflitos pelo uso da água e as apropriações do setor de saneamento por novos atores, a partir do novo arcabouço legal e do contexto de mudanças climáticas, sob a ótica do Objetivo de Desenvolvimento Sustentável 6: “Assegurar a disponibilidade e gestão sustentável da água e saneamento para todos”. O setor do saneamento básico no Brasil tem sido afetado por constantes modificações no Marco Legal, ocorridas na última década. Na medida em que não se atingiu ainda a universalização dos serviços de abastecimento público de água e de esgotamento sanitário, e que a distribuição do saneamento no território se dá de forma desigual entre as populações e regiões, prevalecendo o acesso nos centros urbanos, em detrimento de populações que vivem às margens das cidades, faz-se necessário compreender essas questões à luz da teoria dos conflitos pelo uso da água. Somam-se a esses problemas eventos de seca e crise de governança da água que, associados à injustiça climática, tornam fundamental a inserção das mudanças climáticas e da adaptação climática na agenda do saneamento, para que o acesso à água e ao saneamento possa ser garantido para todos.

Ensuring oil production flow in offshore systems is a critical aspect of oil exploration operations. Any interruption in the production process, whether partial or complete, can result in significant financial losses and cause solid deposition in the production line. Such deposition is due to the crystallization of paraffin and hydrates, a common problem caused by low temperatures in deep waters. Among various mitigation strategies, the Pipe-in-Pipe (PIP) system with active heating is a technological solution to address this issue. This work aimed to perform a numerical simulation of the PIP system using the Finite Volume Method with an implicit formulation, considering the effect of temperature on fluid properties and the system's dynamic response. A control loop using a PI velocity algorithm was developed to maintain the temperature above the critical point. Such simulation studies were performed using the Python programming language in the Anaconda suite. The results showed that the fluid properties greatly influence the dynamic response. The PI control maintained the temperature in the desired condition, demonstrating its operational effectiveness in preventing solid deposition and delivering stable and low-oscillatory behavior. This research emphasizes the significance of taking temperature's impact on fluid properties into account when simulating offshore oil production systems and demonstrates the effectiveness of implementing feedback control.

Published: November 2023

The objective of this work is the comparison of two methodologies used for run-up measurements in a two-dimensional physical model, which represented the protection breakwaters of the Peniche and Ericeira’s ports. Tests were carried out in the scope of the BSafe4sea project. The methodologies used were: a) the traditional measurement of the run-up height with a resistive wave gauge; b) the use of video cameras and image processing techniques images to infer the run-up heights, having its performance evaluated for some of the test conditions. Regarding the results obtained, in terms of Ru2% and Rumax, it was found that the magnitude of the values obtained with the two techniques were quite similar, although the video analysis returned slightly higher values than the wave gauge. Thus, it was found that the video image technique is a viable alternative to measure the run-up. It is recommended the use of diffused light during the tests, along with stabilizing the video camera, to improve the accuracy of the results obtained by the video-based  technique. Besides, the quality of the video image and the use different colors of the armour units of the phicial model, could contribute to achieve better results with the TimeStack methodology.

The editorial of Thermal Engineering of this issue continues the discussion on scientific research needs in vital areas in which thermal engineering has important participation. The main goal is to motivate the readers, within their specialties, to identify possible subjects for their future research. The word "energy" has a historical origin that goes back to ancient Greek philosophy. Derived from the Greek word "energeia", which described the ability of a being or system to perform work or activity, the notion of energy was later incorporated into Latin as "energy" which was also used to describe the vital force that animates living beings. With the development of physics and engineering in the 19th century, the concept of energy was refined and acquired a more concise scientific meaning, linked to the ability to produce changes, or perform work in a physical system. Energy is recognized as the corner stone of several field of knowledge, considered a key concept for science, technology and economics. Energy is fundamental not only in the description and analysis of natural phenomena, but also in discussions related to energy resources, efficiency, sustainability and their impact in the global economy. Understanding and mastering the principles of energy generation is essential for the understanding natural processes, as the conception of strategies to advance the development of technologies and nations. Therefore, energy plays a decisive role in modern society, with significant implications in social and environmental sciences and in the quest for sustainable development. An economic study combined with thermodynamics principles is called thermoeconomic analysis. When taken into consideration, thermoeconomic analysis brings a new perspective for the decision making process when a current of new manufacturing process, product development, new energy generation strategies and its technologic applications are under scrutiny. Several well-known technology applications, from the thermodynamic point of view, have been seen with different lenses when they are studied considering thermoeconomic principles. Such analysis does not weaken previous conclusion but promote development. It does not only enhance the technology itself but also promotes scientific growth, since more scientific investigation must be performed to make a process not only highly efficient but also economic viable.  The mission of Thermal Engineering is to document the scientific progress in areas related to thermal engineering (e.g., energy, oil and renewable fuels). We are confident that we will continue to receive articles’ submissions that contribute to the progress of science.

The increase of wastewater follows the expansion of the world population generating a deficit in basic sanitation and in the sewage collection provided. It is widely known that the United Nations (UN) instituted the 2030 Agenda, a plan for the sustainability of the planet, improvement of people's lives and world prosperity. There are 17 Sustainable Development Goals (SDGs) in the 2030 Agenda. We highlight the SDG 6: “Clean water and sanitation”, which is aimed at basic sanitation and access to drinking water. Currently, the treatment system is divided into three stages: primary, secondary and tertiary. In the secondary stage, one makes use of microorganisms to remove organic matter from the medium, such as microalgae or bacteria. Preference has been given to the use of microalgae, classified as microorganisms of rapid cell growth with photoautotrophic capacity. However, the free state physical dimension of a microalgae makes the treatment process more expensive and potentially, impacts the treatment time, thus burdening the treatment. With that in mind, a method of immobilization of microalgae and the elaboration of a photobioreactor for the treatment of effluents was developed. Immobilization is a practice that consists of fixing algae within small spheres, which simplifies the separation methodology of microorganisms from the treated effluent. The immobilizing medium provides mechanical resistance and protects the culture from possible contamination. In order to demonstrate the functionality of the system, as a means of effluent treatment, a mathematical modeling of the effluent treatment was conceived. Fortran was the programming language used to solve nonlinear differential equations through temporal discretization. Runge-Kutta was the numerical method chosen to solve the equations of the model that are based on Monod’s model. Monod’s model predicts the growth parameters during the life cycle determining the amount of substrates and the number of microalgae along the lag phase, log phase and stabilization level. It also expresses the consumption of the substrates. Thus, the model allows the visualization of the biomass growth, consumption of inorganic substances and the treatment time under study.

In face of the current high energy consumption and demand worldwide, a change to a sustainable energy matrix became one of the pillars for global sustainability. The use of renewable energy has been one of the most attractive subjects in recent years. Several public policies in this matter have been suggested and there are ongoing efforts toward their implementation. The United Nations (UN) proposed what is called the 2030 Agenda, which considers 17 Sustainable Development Goals (SDG) to be achieved by the year 2030. In support of the 2030 Agenda, research on the production of fuels from clean and sustainable sources is being conducted by the scientific community around the world. Fossil fuels are finite and also a major source of environmental pollutants, therefore the choice of using renewable sources of energy tends to be an increasingly growing and attractive alternative. Hydrogen is a fuel with a high heating value and is known as the most abundant gaseous element and simplest in chemical structure. The scientific community researching fuel cells has given much attention to the generation and storage of hydrogen. Besides the electrolytic hydrogen production and the reforming of fossil fuels (e.g., natural gas), hydrogen can be generated by metallic means, for example, by oxidation of aluminum in an alkaline solution. The use of recyclable metals, such as aluminum in this study, is an option for sustainable hydrogen generation processes. Nevertheless, like any chemical reaction, part of the products generated are waste, and some are even harmful to the environment, which makes the production of sustainable fuels unfeasible in case of not finding an appropriate technological industrial destination for such waste. The herein study comprises the investigation of the industrial and technological applications of the products of the hydrogen generation reaction from aluminum. Mastering the chemical reaction parameters of that reaction is paramount for the optimal design of a hydrogen generation system. The disposal of the waste is relevant since it makes the energy supply chain complete and sustainable.

ASTM A-36 marine steel is one of the most used and classified as a medium strength carbon steel. Its characteristics and purpose are in common applications and in metallic structures in general, sawmills, walkways, agricultural machinery and implements, road, rail and oil implements. It is used in angles, round, flat and square bars and I, U and T profiles. In this work, 10 mm sheets, with a V chamfer, were welded using the MIG/MAG process and X-Ray Diffraction measurements were carried out to study of residual stresses caused by the welding process. Then samples were taken for metallography and microscopy in the Scanning Electron Microscope (SEM). They were also performed in the three regions of the weld: base metal (MB); thermally affected zone (ZTA) and in the molten zone (ZF) Brinell hardness tests, to determine the energy stored in the regions of the weld bead. Vickers Microhardness measurements were also made at the ZTA, as it is a very narrow range, to give more precision to the hardness measurements. The X-Ray Diffraction test showed that the air-cooled samples are compressive and the water-cooled samples are tensile. The micrographs of the samples, in the region of the weld, showed that the ferritic phase prevailed in the molten zone. It was also observed the precipitation of carbides and alloying elements, in addition to the presence of martensite. It is concluded, therefore, that the results for the MIG/MAG welding were satisfactory and recommended for the welding of ASTM A-36 Steel.
Integrated Macroeconomic Variables and Financial Growth of the Real Estate Sector in Kenya
Authors:   Kenyatta University, Kenya, Kimemia Jackline Wanjiku
Published: November 2023

The real estate sector has been growing over the years because of major infrastructural developments and high population growth in Kenya. However, the sector has been facing some challenges that have been affecting its growth. This research aimed to assess how macroeconomic factors influence Kenya’s real estate financial success. The research primarily focused on determining inflation, interest rates, exchange rates’ impact and economic growth on Kenya’s real estate sector. The study was underpinned by demand-pull inflation theory, the classical/neo classical theory for interest rates, the classical growth theory and purchasing power parity. The study employed causal research design and targeted three main Kenyan real estate developers in Kenya; Cytonn Investments, Hass Consult, and Knight Frank. In light of the small target population, a census approach was used and the research employed secondary data. As a result, secondary data from the property developers’ yearly market reports from 2016 to 2022 was gathered. Pearson’s correlation and panel data analysis methods were also employed. The findings revealed that the relationship between inflation, interest rates, exchange rates and economic growth revealed R-squared value of 0.8057, implying that the macroeconomic variables explains around 81% of the variation in financial growth within the real estate sector. The study also found that inflation had positive and significant effect on financial growth (β =0.0045187, p=.048<.05), interest rate had positive and significant effect on financial growth (β =0.044177, p=.011<.05), exchange rate had negative but insignificant effect on financial growth (β =-0.0178337, p=0.227>.05), economic growth had positive and significant effect on financial growth (β =0.0980943, p=0.007<.05). The study recommends that financial institutions, policy makers, and developers should implement measures to mitigate the adverse effects of high inflation on the real estate sector. Keywords: Inflation, Interest rates, Exchange rates, Economic growth, Macroeconomics factor.

Influence of Solidification Parameters and Solute Content on the Machinability of Two Lead-Free Babbit Metals
Authors: Costa Maciel André Cruz da
Published: November 2023

Studies suggest that white metal Sn-Sb alloys are the most commonly type of babbit metal used in industry. However, it is necessary to evaluate manufacturing characteristics and solute contents that leads the best machining conditions. This work presents a correlation between solidification parameters and machinability of Sn-2.0wt%Sb and Sn-5.5wt%Sb alloys, solidified in a horizontal directional device, evaluating the influence of solute content on these results. Cutting temperatures were measured in dry necking processes along the length of the ingot. It was observed that the reverse cellular-dendritic transition influenced the cutting temperature results. The range of cell and dendrite spacings varies approximately from 40 to 330 μm on the Sn-2.0wt%Sb alloy and from 15 to 240 μm on the Sn-5,5wt%Sb alloy. In the cellular region, higher values are found for the Sn-5.5wt%Sb alloy, but in the dendritic region, these values were higher for the Sn-2.0wt%Sb alloy.
Teaching Citizenship Through Music Education: A Case Study of a Community Youth Orchestra Program
Authors: Ellerbe Amanda E.
Published: November 2023

This instrumental case study was designed to elicit a nuanced view of perspectives and approaches to citizenship education in one context of music teaching and learning. I chose an El Sistema-inspired youth orchestra program as an instrumental case of citizenship education given the program's explicit mission: to educate students as citizens through intensive ensemble-based music instruction. Throughout one academic year, I conducted observations of the program's routine activities and engaged with five participants in interviews and processes of member reflection. Through these interviews, one program director, two instructors, and two student participants illuminated the phenomenon of citizenship education within the case.

I chose a theoretical framework encompassing Nussbaum's (1998, 2000) world citizenship, as well as categories of legalism and communitarianism, to analyze perspectives and program practices relevant to citizenship education. Primary themes related to participants’ perspectives on citizenship education included expectations for individual development via musical and intrapersonal skills. Additionally, program participants discussed possible instruments of wider social and community change through long-term program outcomes. Based on this analysis, I suggest that organizations intent on citizenship education more closely examine whether classical techniques and curricula inspired by El Sistema best fulfill their missions or if the needs of their communities transcend these traditions.

While conducting a survey of freshwater fungi in the temperate region of southern Australia, we came across two previously undiscovered anamorphic Ascomycota, a phoma-like coelomycete and a dictyochaeta-like hyphomycete. The coelomycetous fungus was classified in the family Morosphaeriaceae (Pleosporales) as a new genus, primarily supported by molecular data. We hereby introduce Minivolcanus unicellularis, the new genus and species, accompanied by both morphological and molecular evidence. Additionally, the dictyochaeta-like hyphomycete was placed in the genus Achrochaeta in the Chaetosphaeriaceae (Chaetosphaeriales) based on a combination of morphological characteristics and phylogenetic analyses utilising ITS, 28S, and TEF1 sequences. This newly identified species is proposed as Achrochaeta rivulata, the second species described within this genus. These findings expand our knowledge of fungal diversity in the region.

The neutrosophic soft set emerges as a highly valuable and efficient adaptation of soft sets, specifically addressing parameterized values of alternatives. However, numerous decision-making algorithms rooted in neutrosophic soft sets often neglect the external factors impacting their effectiveness. This paper introduces the innovative concept of an effective neutrosophic soft expert set, meticulously crafted to encapsulate external influences on both neutrosophic soft sets and expert opinions within a unified model. This eliminates the necessity for additional operations. Notably, our groundbreaking approach seamlessly amalgamates the strengths of the neutrosophic soft expert set and the effective set, resulting in heightened efficiency and realism in this domain. The article comprehensively explores the fundamental operations of an effective neutrosophic soft expert set, elucidating these processes through apt examples. Finally, the paper showcases the practical application of this concept in decision-making problems, providing algorithms and illustrative examples to underscore its efficacy.
Yield of common bean depends on the effect of agrotechnical measures in the conditions of the Forest Steppe of the right bank

Published: November 2023

Aim. To study the peculiarities of the formation of grain productivity of new varieties of common beans depending on the method of sowing and the density of plants. Methods. Field, measuring­weighing ­ for crop harvest accounting, mathematical and statistical. Results. The results of research on the study of the peculiarities of the formation of grain productivity of new varieties of common bean under different methods of sowing and plant density on typical low­humus chernozems, conducted during 2020­2022 at the experimental field of the SE « RF Salivonkivske» of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences of Ukraine, are presented. Conclusions. All varieties of common beans studied in the experiment formed the highest grain productivity under wide­row sowing with a row width of 45 cm and a plant density of 600 thousand/ha ­ 2.72­3.24 t/ha.With the same density and the usual row method of sowing with a row width of 15 cm, crops formed no more than 2.33­2.75 t/ha of grain. With both methods of sowing, both a decrease and an increase in the density of plants on the area negatively affected the formation of the yield of bean crops. Under the optimal technological model of cultivation, the maximum grain productivity ­ at the level of 3.24 t/ha ­ was provided by the bean variety of ordinary Bilosnizhka. Ros and Slavia varieties were inferior to it, respectively by 0.44 and 0.52 t/ha. According to the results of pairwise correlation, a correlation dependence was established for the culture between the amount of grain yield of common bean and hydrothermal conditions during its growing season in relation to: the sum of active temperatures (r = 0.56) and the amount of precipitation (r = 0.57).

Published: November 2023

Passive area sources, such as primary settling tanks, located near wastewater treatment plants can significantly impact odour air quality. This paper presents the variability of odour emissions from the primary settling tank at the Municipal Wastewater Treatment Plant (MWWTP) during a one-year study of odour concentrations determined by dynamic olfactometry. The investigations indicated that the highest monthly average value of the specified odour emission rate was for July (49.89 ouE/m2/s). Preliminary statistical analysis results using a multiple regression model showed the statistical significance of the independent variables in the form of wastewater temperature and retention time concerning the specific odour emission rate values.
Vers une économie de données : réflexions pour hausser la productivité de l’économie québécoise à l’heure de la révolution des données
Authors: Warin Thierry
Published: November 2023

Afin de combler les écarts de richesse du Québec avec ses nombreux partenaires, une réorientation stratégique, impulsée par l’économie des données, semble impérative. Cette transition stratégique devrait s'organiser autour d’une prompte mutation vers une économie axée sur les données, dans le contexte des changements climatiques et de la nouvelle politique industrielle des États-Unis. Il convient de concevoir un modèle de développement qui dépasse la simple augmentation de la production, et qui capitalise sur l'intégration économique du Québec à l'échelle internationale. Face aux impératifs du 21e siècle, le Québec se doit de consolider sa position en tant qu'économie compétitive, écologique et réactive. Néanmoins, l'implémentation d'une telle réorientation nécessite une entente et une collaboration étroite entre diverses parties prenantes, incluant les institutions gouvernementales, le tissu entrepreneurial et la population. Au regard des défis environnementaux et sociaux en constante évolution, cette transformation profonde n'est pas seulement préférable, mais également indispensable.
