Land-based art intervention: Disrupting settler colonial curriculum of public parks
Authors: Bae-Dimitriadis Michelle S. , Meeken Luke Arthur
Published: May 2022

US public parks are ideological sites where settler-colonial curriculum of territoriality is enacted through their organization and design. However, public parks and the rhetorics of nature and democracy that often frame them are rarely problematized as White settler projects occupying the colonized land. Drawing on the scholarship of decolonial, land-based education, this article critiques the narratives of US urban parks’ undergirding settler-colonial curricula and discusses a student-developed artistic intervention executed in a local public park. The ‘Lederer Park Placards Project’ is explored as both pedagogical gesture and art-based research, which engages in settler-colonial critique through site-specific installation to surface the erasure of Indigenous realities and to divert the existing settler-colonial narratives of public places. This art-in-action is discussed as a decolonial gesture intended to disrupt the White, Eurocentric, colonial curricula embedded in US public parks.

Swedish racial innocence on film: To be young, queer and Black in Swedish documentary filmmaking
Authors: Mier-Cruz Benjamin
Published: May 2022

This article analyses two Swedish documentaries, Broadway Playground () and Kiki (), to interrogate how these ethnographic studies of disinvested Black communities in the United States are presented from the standpoint of Swedish racial innocence, a position that implicitly lays claim to neutrality and objectivity by highlighting an imagined national history of ethnic and cultural homogeneity and promoting a perennial myth of race and colour-blindness. In this context, the visual archiving of Black and Brown bodies in low-income neighbourhoods interpellates people of colour – inscribed by non-Whiteness, economic disenfranchisement and non-heteronormativity – into vulnerable documentary film subjects. The article also explores how White Swedish filmmakers negotiate their positions as ‘objective’ witnesses to Black lives and Black bodies, concluding with a call to decentre Whiteness in (Scandinavian) studies of people of colour.
Ezüst-tartalmú anyagok előállítása, jellemzése, azok stabilitásának és fotokatalitikus aktivitásának vizsgálata

One of the most concerning Earth’s problems is the lack of adequate water supply. A modern highly efficient water treatment technology could be a solution to the above-mentioned problem, which could be the advanced oxidation processes (AOP). The best-known type of AOP is heterogeneous photocatalysis. The present doctoral thesis is based on heterogeneous photocatalysis, including Ag-based semiconductors. This current work aimed to synthesize, characterize, investigate of the morphological, structural, and photocatalytic properties of various Ag-containing compounds. The key issue was to investigate the effect of the Ag species formed on the surface of the semiconductor on the stability and photocatalytic activity. Our objectives included the study of the impact of different shape-tailoring agents and alkali metal salt cations on the properties of AgX. The oxoacid salts of Ag, such as silver carbonate and silver phosphate was also investigated. In the case of silver carbonate, the effect of the precursors and reaction temperature were also investigated, while in the case of silver phosphate, the impact of the precursors and their concentration was analysed. The stability of the Ag-based semiconductors is still questionable, while only the silver phosphate is reusable. The effect of the different crystal phases of the titanium dioxide on the formation of the Ag and AgO nanoparticles was also investigated. Ag nanoparticles formed on the surface of the rutile crystal phase, while AgO formed on the surface of the anatase. The latter one showed higher stability.
Complex equilibria in strongly alkaline aqueous solutions containing Ca(II), Al(III) and heptagluconate ions
Authors: Buckó Ákos
Published: May 2022

The interactions of sugar carboxylates with various metal ions have been extensively studied since the very beginning of the last century owing to their widespread applications in industrial processes. Two prominent members of these compounds, namely D-gluconic (GlucH) and D-hepta-gluconic acids (HpglH), find application in the food industry as leavening, flavoring or fat absorption reducing agents, while their sodium salts are often utilized as metal chelators for a wide range of medical and industrial purposes. Small-molecular-weight organic substances, being common constituents of most bauxite ores, are introduced to the Bayer process upon the digestion of raw bauxite. According to the literature, they can form highly stable multinuclear complexes with Ca2+ ions in strongly alkaline medium. Thus, their presence can greatly affect the solubility of Ca(OH)2(s), which is used for NaOH recovery in the so-called recausticization process. Besides their incidental accumulation, these organic compounds sometimes are added intentionally to the process liquor to inhibit the extensive formation of undesired by-products, such as the well-known tricalcium-aluminate, by driving the reaction towards the formation of CaCO3(s). From a process optimization perspective, the interactions of sugar carboxylates with Al3+ ions should also be considered. Until now, the vast majority of previous research dealt only with complexation reactions taking place in acidic to slightly alkaline pH regime (pH < 12), which requires conventional methodology and experimentation. Based on the results reported for systems containing not only Ca2+ but also other metal ions, sugar carboxylates have a high tendency to form heteropolynuclear species, CapMqLr2p+xq–r, where M represents another tri- (Al3+, Fe3+, x = 3) or tetravalent (Th4+, x = 4) metal ion, and L stands for the ligand containing OH and COO– groups.
COMPARISON OF THE RELATIVE CHANGE IN THE RATIO OF PaO2 AND FiO2 DURING PERIODS OF CONTROLLED THERAPEUTIC INTERVENTION AND ROUTINE CARE
Authors: Bachman Thomas Edward
Published: May 2022

Oxygen is the most common drug used in the critical care of infants. There is significant morbidity and mortality associated with excess or inadequate levels. For this reason, an important element of many therapeutic interventions in the ICU requires assessment of their acute impact on oxygenation. It is common to normalize the arterial level of oxygen with the fraction of inspired oxygen (PF-ratio). Further, a change may often be more important than the absolute level. Though the PF-ratio is often reported, it was surmised that the rarely reported, relative magnitude of change in PF-ratio might be a useful metric for assessing the stability and effectiveness of therapy. Therefore, individual patient data from two different studies were evaluated. The cases included periods of therapeutic intervention and periods without intervention, thus permitting the evaluation of the PF-ratio's potential sensitivity to change and thresholds for relevant change. During surfactant administration in extremely preterm infants, the PF-ratio improved at least 25% in 91% of the infants, while 9% showed less than a 10% change. During high-frequency oscillatory rescue in children, the PF-ratio improved at least 25% in 76% of the infants, while 8% showed less than a 10% change. Consideration of thresholds of 50% and 5% reflected low prevalence. In periods of routine care, the prevalence of marked changes was less prevalent but still common (6% and 55%) and periods of little change more prevalent (21% and 21%). We believe this initial work supports the feasibility of using the magnitude of change in PF-ratio and provides a useful stimulus for additional evaluations.

Authors: Castañeda Luz Stella , Henao José Ignacio
Published: May 2022

En este artículo presentamos los resultados de una experiencia en un curso de español I, orientado desde la lingüística textual. Se hace, además, una comparación con los resultados de un curso tradicional, en la Facultad de Economía de la Universidad de Antioquia, durante el primer semestre de 2002. Se realizaron unas pruebas de lectura y escritura con los estudiantes de los semestres II y III, de los tres programas de la facultad: Economía, Contaduría y Administración. Además, se aplicaron las mismas pruebas a 20 de una muestra seleccionada al azar de un grupo de 80, que cursaba español I, en el primer semestre de la carrera. La muestra estuvo compuesta por 114 estudiantes de los programas de Administración, Contaduría y Economía, que habían recibido uno o dos cursos de lengua materna y los 20 alumnos de un curso de Español Los resultados demuestran que los estudiantes no tienen la habilidad para resumir, lo que indica un problema de lectura y escritura bastante crítico en la Facultad de Economía. Lo anterior contrasta con los resultados del curso de Español I que muestran cómo la habilidad de los estudiantes en la escritura de resúmenes fue mucho mejor. Esto demuestra que el problema radica en el tipo de orientación que han recibido en el bachillerato y en el curso de español en el primer semestre.

Controversial Issues and their Impact on the Construction and Reshaping of EFL Learners' Habitus
Authors: Ortiz López Juan Eduardo , Keitt Tracey
Published: May 2022

The following study aims to explore Bourdieu’s notion of habitus and its shaping and re-shaping through exposure of authentic oral input. The study used podcasts as an EFL teaching strategy where learners were expected to confront their dispositions. For the purpose of this study, the mental illness issue was employed as a controversial topic. The research used a grounded theory approach and multi-case study design where three unstructured interviews were implemented in each case along the teaching process. Content analysis was applied and research generated categories emerged from the coding process.  The results reveal that the EFL learning process has the potential to become a subversive form of defying culturally dominant dispositions and to enhance the learners’ probabilities of re-shaping habitus as well as learning a foreign language. According to the findings of this study, the inclusion of authentic controversial podcasts as listening comprehension tasks, which challenge EFL students’ habitus, can become a successful strategy to modify their cultural dispositions along with learning English as a foreign language.
Teacher Education for Language Assessment and Testing: Postgraduate Program Evaluation from its Students’ Perspective
Authors: Papadima-Sophocleous Salomi
Published: May 2022

A review of research conducted on language assessment teacher education (TE) revealed a lack of studies focused on the participants’ perspective. This work concentrates on the evaluation of an online computer-assisted language assessment and testing (CALAT) TE program offered for four consecutive years. The research was based on a conceptual, multidimensional e-learning evaluation model. The data were obtained from 19 practicing language teachers who attended the MA in Computer-Assisted Language Learning via an online anonymous survey focused on 1) the participants’ engagement; 2) course organization, teaching mode, and materials; 3) course strengths; 4) course aspects most helpful for learning; and 5) course aspects that constituted obstacles for learning. The results indicate the participants’ positive attitude towards the course; they highlighted that their knowledge, skills, and principles had improved, as well as the constructivist instructional design and the organization, teaching modes, and materials of the course, which motivated them and involved them in active interaction and collaboration. The participants also perceived the assessment practices performed during the course in a positive way, which favored their learning and teaching practice within the classroom. The results also include some recommendations for course improvement.

Published: May 2022

This study aims to investigate the relationship between emotional intelligence (EI), foreign language anxiety (FLA), and demotivational factors (DF) at a foundation university in Istanbul, Turkey. 148 B1 (intermediate level) students enrolled in the English preparatory school participated in this study. Data were collected from the Turkish-adapted version of the Emotional Intelligence Quotient Inventory (EQ-i), the translated version of the Foreign Language Classroom Anxiety Scale (FLCAS), and the Turkish preparatory school university student demotivational factors towards learning English scale. The findings revealed that the participants were moderately anxious and demotivated in foreign language learning. Moreover, a positive significant correlation was found among EI, FLA, and DF. This study provides pedagogical implications and suggestions for addressing EI, FLA, and DF in English language preparatory programs.
English Teachers Gendered Identities Constructions in their Doings, Sayings and Relatings
Authors: Rodriguez Angela Milena
Published: May 2022

This is a research report of a feminist poststructuralist discourse analysis study carried out in a private University in Tunja, Boyacá, Colombia. This study intended to explore the relation among two EFL university teachers’ pedagogical practices and their gendered identities constructions. Pedagogical practices were framed in the practice architectures: doings, sayings and relatings proposed by Kemmis & Mutton (2012)
It was unveiled that doings, sayings and relatings were sites for and outcomes of teachers´ gendered identities construction. Additionally, teachers´ gendered sayings, doings and relatings were interweaved, juxtaposed, complemented, and contrasted sites where teachers performed different masculinities and femininities based on their capacities to adapt, resist, contest and oppose to heteronormative and patriarchal discourses such as gender roles and normative masculine and feminine features. Those gendered constructions were identified to have possible consequences upon students´ English language leaning and gendered identities construction.
La Estrategia De Escribir Para Aprender: El Caso Del Equilibrio Químico
Authors: Ortiz Cáceres Lucy Margoth , Candela Rodriguez Boris Fernando
Published: May 2022

Diversos estudios han mostrado que la enseñanza de las ciencias esta centrada en el profesor y la disciplina, donde realizan tareas rutinarias y de bajo nivel cognitivo. Para compensar lo anterior, diferentes investigaciones han revelado la importancia que tiene la introducción del lenguaje al aula como una herramienta de pensamiento y aprendizaje de los contenidos científicos. De ahí que, este estudio estudió la incidencia de la estrategia de escribir para aprender como un mediador en la comprensión de la química, así como documentar y representar la comprensión de la disciplina medida por la introducción de dicha estrategia, específicamente, en el concepto del equilibrio químico, con estudiantes de grado undécimo. Se usó una metodología de enfoque mixto por estudio de caso, donde se manejaron dos fases; cuantitativa y cualitativa. Para la primera, se utilizó como instrumento de recolección de información un test, y para la segunda, la observación, notas de campo, videos, documentos de los estudiantes y entrevistas. Los datos cuantitativos se analizaron utilizando el estadístico de ganancia de aprendizaje de Hake, y, los datos cualitativos por medio del software ATLAS.ti con el fin de construir teoría, la cual se trianguló con los resultados del estadístico. Los resultados nos muestran cuatro generalizaciones naturalísticas que permitieron crear una teoría del caso, evidenciando una incidencia positiva en el aprendizaje del concepto estudiado.

Published: May 2022

Este artigo discute o processo formativo inicial de estudantes de licenciatura em Física a partir do Programa Institucional de Bolsas de Iniciação à Docência – PIBID. A discussão é realizada a partir de referências que abordam a constituição da identidade docente no campo formativo do professor de Física. A questão de pesquisa é: Quais aspectos da docência são percebidos e construídos pelos licenciandos/as durante a participação no PIBID? A partir dessa pergunta, os objetivos foram: 1) expor a percepção de licenciandos/as em relação à sua participação no programa e, 2) discutir a constituição da identidade docente a partir do PIBID. A produção dos dados ocorreu a partir de uma entrevista com cada um dos quatro participantes bolsistas. A pesquisa orientou-se pela compreensão e expressão dos sentidos subjacentes relacionados ao PIBID e à formação docente por parte dos sujeitos e isso nos conduziu à utilização dos “núcleos de significação”, como referência metodológica. Num primeiro momento, foram construídos vinte pré-indicadores; secundariamente, seis indicadores e, por fim, os dois núcleos de significação: docência como espaço contraditório e, motivação como importante especificidade para atuação docente. A conclusão do artigo envolve a discussão desses dois núcleos de significação e a pergunta de pesquisa.

Published: May 2022

En los últimos años, están surgiendo nuevas técnicas, propuestas educativas y metodologías que son aplicadas en las aulas de enseñanza. Pero, son pocas las ocasiones en las que se reflexiona sobre si existe o no el marco curricular apropiado para poder aplicar estas iniciativas educativas. En el presente trabajo, se somete a estudio de la acción educativa STEAM, desde el punto de vista curricular, tomando como base de estudio el sistema educativo español, mas concretamente la etapa de Educación Primaria, con el objetivo de comprobar si es o no viable el desarrollo de esta enseñanza STEAM dentro del sistema educativo español. Esta comparación entre STEAM y el currículo de primaria, ha dado como resultados que existen tres áreas de conocimiento que concuerdan con la educación STEAM, que son Matemáticas, Ciencias de la Naturaleza y Educación Artística, así como diferentes aspectos curriculares que avalan el empelo del enfoque STEAM. Por tanto, el sistema educativo deberá apostar por aquellas tendencias educativas integradas, donde diferentes áreas de conocimiento se unen y para desarrollar una enseñanza y aprendizaje mas amplio.
Concepção de professores dos anos iniciais sobre a natureza da ciência e atividades experimentais
Authors: Kliemann Geovana Luiza , Dullius Maria Madalena , Neide Italo Gabriel
Published: May 2022

O presente texto orienta-se a apresentar um estudo desenvolvido a partir de um questionário respondido por 33 professores dos Anos Iniciais, de um município da região do Vale do Taquari, Rio Grande do Sul. O referido questionário foi a ação inicial de um processo de formação continuada, com ênfase em atividades experimentais investigativas na área das Ciências Exatas. O foco do estudo, de cunho qualitativo é socializar e discutir sobre as concepções dos participantes sobre a natureza da ciência e atividades experimentais. A partir da análise às respostas ao questionário, é possível evidenciar uma visão não construtivista dos professores sobre ciências e que poucas vezes atividades experimentais são propostas em suas aulas, principalmente, devido à insegurança. Admitem sua limitação em relação a inserção de novas práticas de ensino nesta área, declaram nunca terem participado de uma formação direcionada ao ensino de Ciências e relatam preferência por participarem de formações em que se proponham atividades práticas, que possam ser levadas para sala de aula. Ademais, as atividades experimentais quando propostas, geralmente visam testar ou transmitir conhecimentos relacionados ao contexto biológico. Tais aspectos podem estar relacionados à compreensão equivocada dos participantes, quanto a natureza da ciência.

Regionales Flächenmanagement in den deutschen Metropolregionen
Authors: Eichhorn Sebastian , Diller Christian , Pehlke David
Published: May 2022

Metropolitan regions result from spatial rescaling processes and region formations and are considered as “soft spaces of governance”, referring to international debates on the “new regionalism”. This paper addresses the criticism that the focus on competitive metropolitan regions distracts from the need for action on classic spatial planning issues. For this, the paper examines and discusses the institutional integration of regional planning in the German metropolitan regions and the activities of regional growth management as well as the regulatory intensity of regional plans based on a group comparison of metropolitan regions. As a result, the thesis of an institutionally fragmented regulatory growth management by regional planning can only be confirmed for a few metropolitan regions, where no relevant institutions and instruments are implemented in the core area. Regarding the “soft” instruments of growth management, the situation is very different. Here, the action potential is not yet fully utilized, even in metropolitan regions with strong institutional cores

The use of information technology in medical practice radically changes the formulation, methods and means of solving most practical problems. The transition to modern information technologies provides new opportunities and improves the quality of service, reduces examination time, increases diagnostic accura-cy, etc. Purpose of the study. Extraction of information about the use of information technology for deci-sion support in medical diagnostics based on the analysis of publications in this field. Materials and meth-ods. For a formal representation of the process of structural-semantic analysis\ of information on the use of IT in medicine, a functional model was built in the IDEF0 notation. When conduc¬ting research in a spe-cific subject area, an analysis of known scientific results and practical solutions is required, for which scien-tific publications posted in various sources are used. There are platforms where information about such da-ta is collected, allowing to determine the quantitative indicators of the publication, their specific character-istics, etc. Semantic analysis tools were used to identify the dynamics of the appea¬rance of publications; to make comparative analysis of the effectiveness of various scientists and research organizations; to deter-mine publishing activity in the journal sector. To determine the features of publishing activity, an addition-al analysis was conducted by the analyst, who is a specialist in semantic analysis. Statistical analysis methods were used to process the collected information. Since a small amount of data has been collected, there is no need to use specialized analysis tools, and Excel tools were used to build charts. Results. The key characteristics of publications on the analyzed topic, the dynamics of the appearance of articles, the most active authors, scientific schools and the most popular journals in which the research results are published are identified. The results of extracting information about research in the field of IT use in cardiology from the most popular publications of active authors are presented. Conclusion. The analysis of publications based on the data of the elibrary.ru platform is a preliminary stage in the study of scientific texts on a se-lected research topic. For the future research, it is necessary to develop an information system to support researchers with complex indicators and data based on the analysis of scientific texts.

There is an actual task of delamination detection in multilayer bimetallic materials. Various methods of nondestructive testing (NDT) are used to solve it, including the method of transient thermal NDT. This method consists in remote registration, visualization and analysis of thermal (temperature) fields, which depend on thermophysical and geometric characteristics, thermal effect capacity and internal structure features of the object. The internal structure defects cause the appearance of abnormal temperature zones on the object surface. Their analysis allows us to judge the presence of changes in the material as a whole or in individual areas. It is possible to understand whether there is a defect under the anomalous site, and what its parameters are, if there is an adequate mathematical model that theoretically describes the dependence of the measuring results on the properties of the object and the selected technological modes. This model is a significant component of thermal NDT systems. For the same object or process, a certain set of mathematical models can be compiled, differing in the number of factors taken into account, the assumptions made, the completeness and accuracy of the description of the state of the object or the conditions of the process. The set of factors is determined by the purpose of the study, and in order to unambiguously determine the model of the thermal state, it is necessary to describe the characteristics of the object (geometric shape and thermophysical characteristics of the material) and the heat exchange process (characteristics of heat sources, initial and boundary conditions). Aim. To analyze the existing mathematical models for the research object – a multilayer bimetallic plate with delaminations between the outer and inner layers, and to identify common approaches to modeling the processes of thermal NDT of multilayer objects. Materials and methods. The structure of the mathematical model of the thermal state of the object is determined. An analytical review of mathematical models of thermal NDT of multilayer objects is performed. Results. The requirements, assumptions and limitations for a mathematical model of thermal NDT of a multilayer bimetallic plate with delamination defects are formulated. Conclusion. On the basis of the considered approaches to the mathematical modeling of the thermal state of multilayer objects with ideal layers contact and delamination defects, the necessary factors for the development of a model for the transient thermal NDT processes of the studied objects are determined.

Modern methods of forecasting time series allow us to obtain very accurate and high-quality forecasts in the presence of retrospective data. However, the results of these methods are determined by the volume and quality of the training sample. When a time series is missing, has a small number of points, or is not reliable at all, time series forecasting methods are ineffective. In this case, it is customary to use approaches to find other indicators that somehow correlate with the desired one, hereinafter referred to as indirect indicators. As part of the work on forecasting socio-economic indicators, it became necessary to form a list of indirect indicators, however, the available solutions for this task do not provide the required reliability. In most cases, these works use data from social networks, forums and other data sources that cannot be considered objective. Since they are an expression of a subjective point of view and may be subject to deliberate falsifications and distortions. Such risks are unacceptable when developing a system created for making managerial decisions at the state level. Aim. Development of methods for searching for indirect indicators based on objective sources of information. These methods make it possible to form a list of indirect indicators without involving experts and eliminating the risks of inaccuracy of primary data. Materials and methods. The research was conducted on the basis of regulatory legal acts of the Russian Fede¬ration and its subjects. This source was chosen because regulatory documents are objective and fundamental documents of the state. They are not a representation of the subjective point of view of the author or a group of persons. For the experiment, a part of the regulatory framework from 2016 to 2021 was collected, related to the categories: agriculture, medicine, social sphere and others. Results. The method of finding indirect indicators is defined, various algorithms for ranking indirect indicators are developed and tested, indirect indicators for several socio-economic indicators are formed. The process of identifying indirect indicators is based on the application of Data Mining and NLP methods to the database of regulatory legal acts of the Russian Federation. Conclusion. The resulting solution allowed us to form a list of N-grams associated with the desired indicator. At this stage, the interpretation of the N-gram into an indicator is carried out with the help of an expert, however, this does not require having competencies in the subject area of the indicator.

The management of organizations essentially depends on the choice of criteria for the functioning and development. At the initial stage of the transition to a market economy, the main criterion for many Russian organizations was cash flow. The following criterion is the net income (financial result), provided sufficient cash flow. The disadvantage of this criterion is its short duration. This paper highlights the value creation approach to management. This approach is widely used in managing Western organizations, but it is pretty new for Russia and requires adaptation in Russian organizations. Purpose of the study. The study’s primary purpose is to develop models and methods to improve the efficiency of organizations in the real sector. This paper discusses the development of a model for assessing the value of an organization by the income method using discounted cash flows. The issue of creation/destruction (increase or decrease) of value with an increase in revenue is being considered. For many Russian organizations, business growth is accompanied by a decrease in value. A criterion for creating value has been developed, non-observance of which will lead to the destruction (increase) of value with an increase in revenue. Materials and methods. A two-period model for evaluating the cost in an analytical form was used. The va¬lue model is designed for “mature” organizations characterized by stable development parameters: operational profitability and capital-to-output ratio. Results. One of the largest metallurgical organizations in Russia is considered as the object of research. Collected and processed initial data on the financial and economic condition of this organization. The valuation model was applied to one of the metallurgical companies in Russia. The accuracy of the calculation results for the valuation was 6% in relation to the actual market price, which can be considered a satisfactory result. Conclusion. This approach simplifies the assessment of the company’s value and develops measures to increase (rather than reduce) its value. An increase in the revenue of an unattractive investment company leads to its value destruction (decrease). Instead of a positive result, stakeholders get a negative one, given the seemingly favorable dynamics of the organization’s development. The proposed model is typical and can be used to analyze the development of many “mature” organizations.

Published: May 2022

For any manager of an agro-industrial enterprise, the use of resources is used for the efficient use of resources: labor, land, working capital and other. For this reason, the production processes of agriculture are already almost completely mechanized around the world, which is the productivity of an enterprise. The next logical step in increasing the productivity of agricultural enterprises is the automation and digitalization of agricultural production. Therefore, in order to remain competitive with the world leaders in agricultural production, it is necessary to integrate IoT technologies. It is predicted that the introduction of modern automation technologies in the agro-industrial complex will increase yields more than the inventions of the tractor, herbicides and GMOs. City farming is gradually becoming such a solution. In some megacities, urban farms are built on the rooftops of buildings, and in some places there are entire skyscra¬pers with vertical farms. Experts say that the quality and environmental friendliness of products grown in this way is much higher than that of counterparts grown in a traditional way. In this regard, the relevance in creating an application for a smart farm has been identified. Such an application will allow you to be more attentive to all parameters of plant growth thanks to sensors for humidity, light, temperature and other data that can be transmitted to a smartphone. The purpose of the study is to develop a management and monitoring system for a city farm. Materials and methods. The mobile application is implemented using the Xamarin framework in C# and JavaScript. The firmware for the microcontroller is written in C. Results. The paper provides an overview of management and monitoring systems for smart farms, a methodological comparison of advantages and disadvantages. The architecture of the control and monitoring system was also discovered. Implemented a mobile application and software. The functionality and design of the mobile application has been tested on various devices. Conclusion. The city farm management and monitoring system has been successfully developed. As further scientific work, it is planned to develop a mathematical model for more optimal farm management. This work can be useful in the field of decentralized agriculture.

Silica-rich sodalite zeolite has been synthesized by ultrasound treatment and hydrothermal temperature variation. This study aimed to determine the effect of ultrasound treatment and hydrothermal temperature variations on the crystallinity, hydrophobicity, and structural properties of silica-rich sodalite zeolite. The synthesis was conducted by reacting a sodium aluminate and sodium silicate solution by varying Si/Al ratios of 20, 30, 40, 60, 80, and 90. The next step was to characterize the product. The product with the best crystallinity was used as a reference to determine the effect of ultrasound and hydrothermal temperature. The reaction gel was treated with and without ultrasound and hydrothermal using autoclave at 100, 150, and 200°C for 24 hours. The last step was the product characterization using XRD, FTIR, and GSA. The XRD showed similarity peaks at 2θ = 14.058°; 24.41°; 31.73°; 34.75°; 42.88°. The best crystallinity was silica-rich sodalite zeolite with a Si/Al ratio of 30. Meanwhile, silica-rich sodalite zeolite peaks were obtained at 2θ = 14.16°, 24.66°, 31.99°, 35.13°, and 43.39° by ultrasound treatment and hydrothermal temperature variation (100, 150, and 200°C). Ultrasound treatment revealed the presence of other peaks besides sodalite at 2θ = 19.05° and 27°, where these peaks were referred to as SAPO-56. In conclusion, the degree of crystallinity increased with increasing temperature, decreasing Si-OH/Si-O-Si showed increased hydrophobic properties. Increasing the hydrothermal temperature of 150 and 200°C with and without ultrasound treatment increased the surface area significantly to 114.137 m2/g and 160.717 m2/g, and the pore volume of sodalite with a Si/Al ratio of 30 to 0.318 cc/g and 0.274 cc/g.

The purpose of the present work is to investigate the corrosion sensitivity of pipelines of oil and gas wells under complex environmental conditions (i.e., the primary and secondary relationship of the influence of different environmental factors on pipeline corrosion). The orthogonal experiment is introduced to design the experimental scheme. The weight loss method is employed to analyze the average corrosion rate of N80 steel under different environmental conditions. And then the scanning electron microscope is used to explore the surface and cross-section corrosion morphology of the corrosion products. Besides, the components of corrosion products are obtained by the energy spectrum analysis. The research results indicate that H2S partial pressure is the most sensitive factor to the corrosion of N80 pipeline and the influence of CO2 partial pressure on corrosion of N80 pipeline is weaker than Cl− concentration and temperature in the South China Sea. The study can help the oil drilling engineering search for direct and effective corrosion inhibitors under complex environmental conditions.
Enforcement of Fines and Other Pecuniary Obligations Imposed by the ECB
Authors: Hayden Helene
Published: May 2022

The overall studyprovides a comprehensive analysis of the enforcement of fines and other pecuniary obligations imposed by the ECB within the Eurosystem and Single Supervisory Mechanism (SSM) and it highlights how the mismatch between European and national law inherent in Art. 299 TFEU could be resolved. While the focus in Part I was on the European law requirements with regard to the enforcement of pecuniary obligations imposed by the ECB, Part II focuses on the Member State’s (MS) perspective and is based on a comparative analysis of the respective data collected in 2020 via a questionnaire survey in 21 MSs. This data will serve not only to have a closer look if and how the European law requirements are implemented but also to analyse how effective the different legal systems are and to identify gaps in legal protection in practice. The results of the analysis of the realisation at national level are not only relevant for the enforcement of obligations imposed by the ECB, but rather also for the enforcement of legal acts of the Council and the EC

Impact of the COVID-19 Pandemic on Company Law. Shareholders’ Meetings and Resolutions
Authors: Pinior Piotr
Published: May 2022

The world is currently facing a COVID-19 pandemic which exerts a considerable impact on all areas of society. The need to avoid personal contact with other people gives rise to major problems in personal life, education, labor market, services and many others. The public had to rapidly adjust to the new situation and national legislators have played a pivotal role by making amendments to national legal orders to facilitate everyday life. The difficulties affected the functioning of companies’ organs, in particular, the adoption of resolutions by shareholders’ meetings. Due to the obstacles in the functioning of these bodies, the legislators were forced to make amendments to company law that allow for the adoption of resolutions and the exercise of shareholders’ rights without the physical attendance at the meeting. The aim of this paper is to carry out a brief comparative analysis of the regulations concerning the use of electronic communication means at shareholders’ meetings in Poland and in some selected European legal orders and formulate de lege ferenda postulates for the legislators to introduce flexible instruments that will allow companies to operate using electronic means on a larger scale and simultaneously protect shareholders’ rights.

The study comprised thirteen pre-service teachers who were purposely sampled. Even though there are different online platforms that the pre-service teachers could have used, they all delivered their lessons through WhatsApp because of the several benefits attached to it such as ease and flexibility to use, low cost of WhatsApp bundles, various functions and the fact that it can be used anywhere at any time. The pre-service teachers faced several challenges during peer teaching using WhatsApp such as lack of smartphones, a flood of messages, human interruption, unavailability of electricity and internet and the nature of mathematics concepts. Difficulty in maintaining discipline, assessing learners’ progress was also difficult and it was time-consuming to prepare and deliver lessons using WhatsApp. The pre-service teachers suggested that the prices of online devices such as smartphones and WIFI should be subsidized. In addition, they suggested that lessons should be recorded for the learners and that parents should be involved in their children’s learning by encouraging them to provide online tools and educating them on online teaching and learning. The study recommends that pre-service teachers need to be trained on the use of online platforms so that they are equipped for any eventuality such as the COVID- 19 pandemic.
Psychological Ownership in Heterogeneous Family Firms: A Promising Path and a Call for Further Investigation
Authors: Mustafa Michael , Labaki Rania , Henssen Bart
Published: May 2022

This essay responds to recent calls for more research on family firms’ heterogeneity from an ownership perspective. We complement the legal and economic view of ownership by focusing on the concept of psychological ownership (feeling of possessions) in family firms. We explore its dynamics, processes and implications as well as its limited inclusion in the family business field to date. Building on a brief review of the literature, we suggest the concept of psychological ownership can help expand our understanding of family firms’ heterogeneity. Additionally, we put forward a future research agenda for psychological ownership in family firms.
