Photo-Fenton Catalyzed by Cu2O/Al2O3: Bisphenol (BPA) Mineralization Driven by UV and Visible Light
Authors: Olea-Mejia Oscar , Brewer Sharon , Donkor Kingsley , Amado-Piña Deysi , Natividad Reyna
Published: November 2022

This work aimed to demonstrate Cu2O/Al2O3 as a catalyst of the photo-Fenton process in the UV and visible spectra. Cu2O nanoparticles were synthesized by laser ablation in liquid and supported on Al2O3. The catalytic activity of the resulting solid was assessed in the mineralization of bisphenol A (BPA). The studied variables were type of Al2O3α and γ, Cu content (0.5 and 1%), and H2O2 concentration (1, 5, and 10 times the stoichiometric amount). The response variables were BPA concentration and total organic carbon (TOC) removal percentage. The presence of Cu2O nanoparticles (11 nm) with an irregular sphere-like shape was confirmed by transmission electron microscopy (TEM) and their dispersion over the catalytic surface was verified by energy-dispersed spectroscopy (EDS). These particles improve ·OH radical production, and thus a 100% removal of BPA is achieved along with ca. 91% mineralization in 60 min. The BPA oxidation rate is increased one order of magnitude compared to photolysis and doubles that for H2O2 + UV. An increase of 40% in the initial oxidation rate of BPA was observed when switching from α-Al2O3 to γ-Al2O3. 4-hydroxybenzaldehyde, 4-hydroxybenzoic acid, acetaldehyde, and acetic acid are the BPA oxidation by-products identified using LC/MS and based on this a reaction pathway was proposed. Finally, it was also concluded that the synthesized catalyst exhibits catalytic activity not only in the UV spectrum but also in the visible one under circumneutral pH. Therefore, Cu2O/Al2O3 can be recommended to conduct a solar photo-Fenton reaction that can degrade other types of molecules.

Water resources management in estuarine environments for water supply and environmental protection typically requires estimates of salinity for various flow and operational conditions. This study develops and applies two novel deep learning (DL) models, a residual long short-term memory (Res-LSTM) network, and a residual gated recurrent unit (Res-GRU) model, in estimating the spatial and temporal variations of salinity. Four other machine learning (ML) models, previously developed and reported, consisting of multi-layer perceptron (MLP), residual network (ResNet), LSTM, and GRU are utilized as the baseline models to benchmark the performance of the two novel models. All six models are applied at 23 study locations in the Sacramento–San Joaquin Delta (Delta), the hub of California’s water supply system. Model input features include observed or calculated tidal stage (water level), flow and salinity at model upstream boundaries, salinity control gate operations, crop consumptive use, and pumping for the period of 2001–2019. Meanwhile, field observations of salinity at the study locations during the same period are also utilized for the development of the predictive use of the models. Results indicate that the proposed DL models generally outperform the baseline models in simulating and predicting salinity on both daily and hourly scales at the study locations. The absolute bias is generally less than 5%. The correlation coefficients and Nash–Sutcliffe efficiency values are close to 1. Particularly, Res-LSTM has slightly superior performance over Res-GRU. Moreover, the study investigates the overfitting issues of both the DL and baseline models. The investigation indicates that overfitting is not notable. Finally, the study compares the performance of Res-LSTM against that of an operational process-based salinity model. It is shown Res-LSTM outperforms the process-based model consistently across all study locations. Overall, the study demonstrates the feasibility of DL-based models in supplementing the existing operational models in providing accurate and real-time estimates of salinity to inform water management decision making.

Published: November 2022

A novel, simple numerical method to determine the pore and surface diffusivities in adsorbents from a single experimental concentration decay curve obtained using the batch adsorption technique was investigated in this study. The pore and surface diffusion coefficients were determined based on the conventional parallel diffusion model in its dimensionless form using a theoretical model correlation. The model assumed that the film mass transfer resistance was negligible, i.e., the condition with a large Biot number, from the single concentration decay curve. The procedure for determining the kinetic parameters was investigated, and the effectiveness of the proposed simple method was validated by comparing the parameters with those reported previously. The single decay curve of p-nitrophenol, obtained by the batch adsorption system using granular activated carbon as an adsorbent, was used for validation. The diffusivities determined by the simple method corresponded fairly well with the diffusivities reported previously.

Published: November 2022

We investigate the liquid crystal (LC) phase behaviors of the sodium cholate stabilized single-walled carbon nanotube (SWCNT) aqueous dispersions with different SWCNT aspect ratios. The isotropic-to-nematic phase transition occurs at a lower concentration for the SWCNT dispersion with a larger aspect ratio, which is expected by the Onsager theory. The well-aligned film is successfully fabricated from the dispersion with the higher SWCNT aspect ratio by the simple blade coating. We also prepare the SWCNT dispersions with different surfactants, sodium deoxycholate, and sodium taurodeoxycholate, changing the surface condition of SWCNTs, which may affect the LC transition concentrations.

Authors: Cherepanov V. V. , Popov E. V.
Published: November 2022

Aim. The presented study aims to develop a concept of digital transformation through the example of an industrial enterprise to enable comprehensive and efficient digital transformation of separate processes, their stages, and even entire organizations in the industrial sphere.

Tasks. The authors determine a series of preparatory and transformational steps that can be executed with little dependence on the competencies of the head of digital transformation and would facilitate digital transformation in the organization; develop a methodology in the form of an integrated methodological framework that makes it possible to formalize the owner of the organization as the principal and the head of digital transformation as the agent in the process of its implementation.

Methods. The methodological basis of the study includes research in the field of digital transformation and the authors’ analysis of digital transformation cases.

Results. The concept of digital transformation developed in the study contains the necessary methodological tools for the formation of a digital transformation program and its implementation at an industrial enterprise. The created methodological basis of digital transformation makes it possible to consistently plan and carry it out, regardless of the level of digital maturity of the transformed process and organization or the level of competence of the head of digital transformation.

Conclusions. The concept of digital transformation developed by the authors makes it possible to transfer digital transformation events or a large-scale program from the category of managerial search for solutions with a high level of uncertainty to the category of a methodologically sound reproducible and feasible set of actions with a high level of effectiveness. In other words, the proposed concept of digital transformation makes it not an “art” with unpredictable results depending on the competencies of the organizer, but rather a reproducible activity with predictable achievements.
Helminth fauna of mouse-like rodents in the territory of Moscow City
Authors: Karmanova T. N. , Gorelysheva D. I.
Published: November 2022

Conditions of the urban environment have a significant impact on the ecology of animals, including helminth communities. The response of the helminth community to ecological imbalance and their adaptation to life in the urban environment remain an urgent problem in parasitology. In this study, we aimed to compare the species diversity and distribution of helminths in urban forest parks with varying degrees of anthropogenic pressure. In urbanized territories of 5 locations of the city of Moscow, the infestation parameters of model rodent species were assessed in comparison with a natural, slightly disturbed territory (the scientific and experimental base “Chernogolovka”). In the four most common rodent species (n = 158), Apodemus agrarius, Sylvaemus uralensis, Microtus arvalis, and Clethrionomys glareolus, caught by Hero's traps, the gastrointestinal tract was removed, the number and species of parasites were determined, and the infestation was assessed by 3 parameters. The species composition of helminths and the presence of three parasite classes in the composition of the helminth fauna of the studied species expectedly corresponded to the characteristics of disturbed areas. In addition, a change in the dominant helminth species (H. polygyrus to H. Spumosa) was noted, which indicated a significant influence of the helminth fauna of synanthropic species on the composition of the parasite communities of wild species living in the city. Our study contributes to the accumulation of information on the species composition of endoparasite communities of murine rodents in the city of Moscow, which is important for compiling an up-to-date epidemiological picture of the city.

Published: November 2022

The influence of the major components of plant root exudates, namely, carboxylic acids (succinic acid as an example) and secondary plant phenolic metabolites – flavonoids (rutin as an example), on the microbial degradation of the three-ring polycyclic aromatic hydrocarbon (PAH) phenanthrene by rhizobacterium Mycolicibacterium gilvum was studied. The destructive activity of this microorganism relative to PAH was studied by cultivating it in a liquid mineral medium containing phenanthrene (0.2 g/L), succinic acid (5 g/L), and rutin (0, 0.05, 0.1 or 0.2 mmol/L) at 30°C under aeration on a shaker (130 rpm) for 14 days. The stimulating effect of succinic acid and rutin on the microbial degradation of phenanthrene was revealed. It was found that carboxylate was utilized as the main growth substrate for the microorganism, while flavonol and PAH had little effect on bacterial growth. Rutin had no antimicrobial effect on the microorganisms studied; on the contrary, in combination with succinic acid, it significantly increased the biomass growth. At high concentrations (0.1 and 0.2 mmol/L), rutin inhibited the degradation of phenanthrene by 22 and 56%, respectively. However, at a concentration of 0.05 mmol/L rutin increased phenanthrene degradation by 10%. Thus, the results obtained showed the dependence of the PAH microbial degradation efficiency on the presence, combination, and concentration of the plant root exudate constituents.

Authors: Anikin V. V. , Kondratev E. N.
Published: November 2022

The paper presents data of ecological Lepidoptera groups in the nests of the sand martin (Riparia riparia (Linnaeus, 1758)) on the Saratov region territory. The material was collected in R. riparia colonies within five districts of the Saratov region in different 2019–2021 seasons. Three clusters were identified for 13 Lepidoptera species belonging to 10 families during our statistical data analysis. One cluster covers typical inhabitants of burrows and is represented by a single species, Infurcitinea rumelicella (Rebel, 1903). Atypical species comprise the remaining two clusters. All the presented species, namely: Acompsia cinerella (Clerck, 1759), Niditinea fuscella (Linnaeus, 1758), Brachmia dimidiella ([Denis & Schiffermüller], 1775), Epermenia ochreomaculella (Milliére, 1854), Caloptilia fidella (Reutti, 1853), Laodamia faecella (Zeller, 1839), Polypogon tentacularia (Linnaeus, 1758), Borkhausenia fuscescens (Haworth, 1828), Acleris forsskaleana (Linnaeus, 1758), Cochylidia implicitana (Wocke, 1856), Loxostege sticticalis (Linnaeus, 1758) are not typical for the nests of the sand martin. Our conducted observations of the species composition showed its being extremely poor relative to representatives of the nest-dwelling fauna, which is associated with the nest inaccessibility of burrowing birds, which R. riparia belongs too.

La vivienda es el principal activo de la mayoría de los hogares y es un determinante importante de sus decisiones de financiamiento y consumo. A pesar de que la medición de la riqueza por vivienda es crucial para comprender el comportamiento económico de los hogares, este indicador no está disponible en México debido a la falta de datos comúnmente requeridos para su estimación. Este documento propone una metodología de cálculo más flexible, basada en el enfoque de cantidades por precios y el método de inventarios perpetuos, que relaja los requerimientos de información al tiempo que cumple con las directrices internacionales. Nuestros resultados sugieren que la riqueza por vivienda en México ha seguido una tendencia ascendente desde 2005, alcanzando niveles alrededor del 187% y 202% del PIB en 2020. Además, nuestra medida permite el cálculo de otros indicadores de los hogares, tales como el capital de vivienda y la riqueza neta total del sector

Een professionele wielrenner zonder ‘moraal’ komt de berg niet op in een zware etappe van de Tour de France.1 Met professionals als leraren, advoca- ten, gezinsvoogden, en rechters is het eigenlijk niet anders. Ze kunnen een eind komen zonder moraal maar de top zullen ze uiteindelijk niet halen. Dat wil zeggen: echt goed werk, in de brede zin van het woord, zullen ze niet leveren. Want echt goed werk vertoont niet alleen de trekken van bij- na ambachtelijk vakmanschap, wetenschappelijk onderbouwde expertise, technische en methodische voortreffelijkheid, een door gedegen training gecultiveerd oordeelsvermogen. Echt goed professioneel werk is werk dat ook de toets van morele kritiek doorstaat, en meer dan dat, het is werk dat morele lof oogst omdat met minder dan het beste geen genoegen geno- men is. En gaat het hier om goed werk, dan kan het niet anders dan ook over de ‘goede werker’ gaan, zeker als we het over professionals hebben. Het bekende en wijds opgezette Amerikaanse Good Work onderzoekspro- ject brengt echt goed werk behulpzaam op formule met drie E’s. De E van excellent werk, van werk dat ethisch deugt, maar ook, ten slotte, van werk dat zinvol (noem het ‘enerverend’ of ‘engagerend’) is voor degene die het uitvoert, de goede professionals dus (Good Work Project team, 2008, p. 5). Die drie hangen onlosmakelijk samen als in een driedubbele helix (idem) maar we concentreren ons in deze beroepsethische bundel op de ethische dimensie van goed werk.

In het boek Discipline, toezicht en straf: de geboorte van de gevangenis van Michel Foucault staat een bekende illustratie, waarop een grillig kromge- groeide boom te zien is die met een touw aan een stevige rechte paal is vastgebonden. Foucault ontleent de afbeelding aan een Frans boek over orthopedie uit 1741. Er bestaat weinig twijfel over de vraag welke betekenis Mr. Andry, de auteur van het boek, aan het plaatje heeft willen toekennen: net zoals de paal en het touw de boom steunen en hem helpen een stevige, rechte en gezonde boom te worden, zo helpt de orthopedie lichamelijke afwijkingen te voorkomen en te herstellen.

En el presente trabajo se propone rebajar una de las condiciones para adoptar un principio lógico. La condición a la cual se rebaja tiene que ver con la aceptación del conocimiento proposicional y, por otro lado, con contemplar las consecuencias prácticas efectivas beneficiosas que nos da un principio lógico. Para esto, primero se realiza una reconstrucción del problema de la adopción entendido como una reductio, mostrando que el problema se encuentra en el modo en que los agentes aceptan el conocimiento proposicional. Luego de haber diagnosticado el problema muestro que al rebajar el peso de la adopción es necesario introducir las consecuencias prácticas efectivas beneficiosas del principio lógico para que el agente pueda adoptar el principio lógico. Por último se analizan algunas posibles objeciones a mi propuesta y doy una breve conclusión.
Accurate Prediction of Workflow using Dual-Stage Learning to Reduce Task Execution Time
Authors: N. Bhalaji
Published: November 2022

As the number of cloud data centres continues to expand rapidly, one of the biggest worries is how to keep up with the energy demands of all these new servers without negatively impacting system dependability and availability or raising the price of power for service providers. Workflow task performance prediction for variable input data is crucial to several methods, including scheduling and resource provisioning. However, it is challenging to create such estimations in the cloud. The suggested system's two-stage forecasts and parameters that account for runtime data, allow for very precise predictions. The workflow is smooth, and obviously the task execution time is adequate. This strategy beats the state-of-the-art prediction techniques, as shown by empirical data. It is demonstrated that the models of this form, predicting workflow for a given cloud, can be easily transferred to other clouds with little effort and error.

Published: November 2022

Free space optics is a kind of broadband communication technique that transmits the signals, in the atmosphere through laser beams. In some cases, the laser beams are replaced with infrared and modified beams. Free Space Optics (FSO) is also referred as Free Space Photonics that works same as the principle of fiber optic communication where the source beams are transferred through air medium. In the traditional fiber optic communication, the optical fibers were used for transferring the beam signals. The FSO methodology is widely employed in various ubiquitous applications for their cost and deployment effectiveness. The motive of the work is to explore the concepts and theories behind the operation of different FSO models with their recent progress.

Currently, there are more than 440 nuclear fission reactors in 30 countries generating about 12% of the world’s supply of electricity [1, 2]. Most of the commercial nuclear power reactors are light water reactors (LWRs). One of the three types of LWRs is the pressurised water reactor (PWR), which is the most common construction of nuclear reactors and constitutes about 60% of the world’s nuclear power plants [3]. In a PWR, light water serves as a coolant which removes the heat produced inside the reactor core by the nuclear fission reaction. Moreover, in PWR, water is also a moderator which slows down neutrons that are released during the nuclear fission process [4].

In this article the effects of either mutual reinforcement, or incongruity, between the mass media and the social networks of political information are analyzed. The political in formation exposure of South Africa's white university students serve as the basis for research. The article illuminates, in terms of political socialization theory, the differential exposure of the English and Afrikaans students. The findings clarify the role of the mass media in relation to other sources of political information in a rapidly changing society. It emphasizes the dependence on the mass media for political information. Yet it also shows how social networks which are more diverse for the English than for the Afrikaans students moderate the political socialization role of the mass media
Orkney snork nie!
Authors: Bouwer Stephan
Published: November 2022

In this article it is postulated that a critical/analytical reading of TV programmes should be an eclectic (or multi-disciplinary) transaction. With the "auteurism" viewpoint (vide Lapsley et all, Reader-response Criti cism (Allen et al) and the British Cul tural Studies (Birmingham) approach (Fiske et al) as point of departure, the popular Afrikaans sitcom ORK NEY SNORK NIE! (SABC TV1) is used as "vehicle" to demonstrate that TV viewing is a highly entangled, inter textual, communication transaction. The question of genre delimination, as an ideological implement, is also mooted. Two diagrammes (the nar ratological prose model and the "6 phase" communication model) are used as illustration to elucidate on encoding/decoding, with special emphasis on the contribution of the various sender collaborators and on author Esterhuizen as primary source of signification. With due allowance for the TV viewer as a reader who "negotiates" and "opposes", to use Althusser's terms, this article is an attempt at TV deconstruction in or der to demonstrate certain theories of pictorial communication and dis course analysis.
Nie-verbale gedrag
Authors: Terblanche Frederick
Published: November 2022

One of the major issues surrounding the concept of non-verbal communica tion is which forms of non-verbal behaviour qualify as communication. It is in this regard that this article strives to formulate some points of departure for a teaching approach to non-verbal communication. The main characteristics of the three most important perspectives relating to non-verbal communication are as sessed. By combining certain aspects of the three perspectives, omitting others and adding new perspectives, it is proposed that one can distinguish between communication, ascribed communication and non-communica tion. Communication behaviour encom passes all forms of intentional or goal directed behaviour, or behaviour for which proof exists that encoding is tak ing place and is being interpreted as such. Ascribed communication encompasses indicative behaviour upon which conclusions are based, or to which intention or meaning is ascribed. Non-communicative behaviour encom passes non-verbal behaviour which is neither goal-directed nor interpreted as such. Although this distinction should be scientifically refined even further, it may serve as a basis for a description of non-verbal communication.
Reframing South African TV news as peace journalism
Authors: Lynch Jake
Published: November 2022

This article presents an indicative sample from the results of an experiment that gatheredaudience responses to television news that was coded as “war journalism” and “peacejournalism” respectively, in South Africa, during April 2012. From the peace journalism model,evaluative criteria were derived under a set of five headings for content analysis of two televisionnews programmes and four newspapers. Distinctions under the headings were particularisedfor individual stories by critical discourse analysis to disclose potential sources of influencetransmitted into audience frames. The test material was then coded to fall within the upper andlower peace journalism quartiles of the ‘idiom and range’ of journalism, as currently practised,demonstrated by the content analysis. Transcripts of discussions by focus groups who saw thematerial, as well as written notes made whilst viewing by a larger sample of participants, werethemed according to Entman’s model of framing (1993), where causal interpretation is linked totreatment recommendation. From these interim findings, peace journalism proved to be ideationalin the sense that peace journalism viewers were more likely to perceive structural and/or systemicexplanations for problems, and more likely to see opportunities for therapeutic and/or cooperativeremedies to be applied through exertions of political agency from different levels.
Steunwerwing in Suid-Afrika
Authors: Kleynhans Yolanda
Published: November 2022

This article focuses on lobbying in South Africa, with special reference to the business sector. Lobbying does indeed take place in South Africa, but is on an ad hoc and unstructured basis when compared with the USA, for example. Most of the persons who perform local lobbying functions do so in a part-time capacity while maintaining major positions as interest-group officials, PROS In companies or as corporate executives. Rather than trying to measure their influence In the policy-making process, the study analyses the level of interest group activity and the lobbying techniques they employ. The institutional foci of lobbying activities are also identified. Conceptual and comparative perspectives are integrated with the empirical data.
Specific inferior and superior role portrayals in multi-racial television advertisements
Authors: Van der Waldt De la Rey
Published: November 2022

The attitude analysis of specific inferior and superior role portrayals is a direct result of the article published In Communicare (1988: 49-54) on general role portrayals. The respondents analysed role portrayals of models in 12 different multi-racial television advertisements. The results indicate important differences in the perception of these roles. Finally an original model of role perception is put forward. Van der Waldt (1988:49) stated that the diversity of approaches to the analysis of advertising has led to the discussion and application of Festinger's (1954) theory of social comparison, Grubb & Grathwohl's (1967) theory of self-concept related to product consumption, Sarbin & Allen's (1968) role theory and lastly Bandura's (1977) theory of social learning. Results indicated (Van der Waldt, 1988:53) that these theories clustered together separately under four different factors. All except Bandura's social learning theory clustered under a particular factor. It seems therefore important to pay more attention to this theory.
Vrye Weekblad and Post·Apartheid Mania
Authors: Tomaselli Keyan , Louw Eric
Published: November 2022

In this commentary the authors express their opinion on the role that the Vrye Weekblad in particular and the Press in general, can play in a post-apartheid South Africa. The article is not based on any empirical quantitative research. Rather, It should be seen as a critical analysis of comtemporary conjecture surrounding literature pertaining to this specific topic. The authors postulate that the Vrye Weekblad is ofter mistakenly portrayed as a radical newspaper by those who feel the mos threatened by the possible conse quences that its messages can produce. The value of this particular medium lles In the fact that it will help ensure that Afrikaans, as a language, will survive. It Is able to fulfil this function by showing that Afrikaans need not always be im. mediately equated with racism or suppression, but in sharp contrast, that Afrikaans can be synonomous with democracy. The difficulties and challenges facing the Vrye Weekblad (and other media) as a variable that will play a vital role in not only moulding, but also influencing a post-apartheid South Africa, are highlighted
Kabaret as 'n 'Alternatiewe' Kommunikasieverrigting
Authors: Bouwer Stephan
Published: November 2022

In this article an attempt is made to examine cabaret, a sub-genre of Dra ma, as an "alternative" communication transaction. Firstly, reference is made to the actual theatrical perfor mance as two-way communication (vide, Inter alla, Keir Elam) between a "cluster" of senders ( theatrical collaborators) and the receivers (= audlence). The history of cabaret is related briefly, with special reference to certain conventions that were es tablished In Paris (1881) and the Ber lin cabaret of the Welmar Republic - e.g. cross-dressing and other shock tactics, in order to high-light the mes sage as such. Subsequently, cabaret as "protest art"- Is examined: It is noted that most definitions, ex pressed by various historians and theoreticians, stress the fact that cabaret, primarily, is protest art. It is postulated that senders often rely on the "sleeper effect" to get the mes sage across. The emotive term (in the South African context) "alternative" is discussed before an attempt is made to demonstrate that discourse "Intervention" can create new mes sages out of existing literature through Juxtapositions. This article is based on a paper that was read at the annual SACOMM conference on September 6, 1990 at the HSRC, Pretoria
Simplified Seismic Evaluation of Aged Corrosion Damaged Reinforced Concrete Bridge Columns as Part of Simplified Semi-Quantitative Assessment Framework
Authors: Mohammed Amina , Almansour Husham , Martín-Pérez Beatriz
Published: November 2022

Severe reinforcement corrosion significantly reduces the structural stiffness and load-carrying capacity of Reinforced Concrete (RC) columns. The interactive effects of corrosion-induced damage and repeated traffic load cycles further accelerate bridge columns' load-carrying capacity deterioration. When subjected to seismic excitation, corrosion-affected RC columns could show a dynamic response significantly different from non-affected columns. This paper proposes a Simplified Nonlinear finite element Seismic Analysis approach (SNLSA) based on enhanced inspection of corrosion-damaged RC columns and as a handy tool for evaluating their seismic response, which is a crucial step in a semi-quantitative assessment framework. The SNLSA integrates Nonlinear Sectional Analysis (NLSA), DRAIN-RC computer program for nonlinear time history analysis, and Takeda's hysteretic analysis. The approach provides three options: (i) establish the staged failure mechanism using express analysis simulating quasi-static loading up to failure; (ii) use a more comprehensive analysis simulating cyclic loading developing the hysteretic relationships; and (iii) conduct a nonlinear full time-history analysis. The SNLSA can estimate the significant contraction of the column interaction capacity when subjected to severe corrosion damage for all load-over-capacity ratios. The SNLSA quantitatively predicts the change in the seismic performance of corrosion-affected versus as-built bridge columns. The approach could also be used to select the appropriate design option for bridge columns in seismic-critical zones.

The aim of the research was to measure the impact of the COVID-19 pandemic on the dynamics of financial instruments in international trade. The study examined the dynamics of price changes and determined the impact of the COVID-19 pandemic on the price of futures contracts on the global market. The impact of the COVID-19 pandemic on the futures volatility dynamics in the global financial market was explored for major commodity groups. The least-squares method was used as the main regression testing tool, while dynamics of the indicators was assessed through graphical and trends methods. The study involves the World Bank’s data for 2000-2021. The impact of the COVID-19 pandemic on the coal, natural gas, metals, beverage and food futures price on the global financial market was established and proved to be statistically significant. It was found that the pandemic had a statistically significant impact on the volatility of futures for coal, natural gas and tin on the global financial market. The futures price is being affected by the COVID-19 pandemic because of the collapse of global supply chains and countries’ protectionist measures. In aggregate, this produces imbalances in the distribution of goods in the world and impedes their flow. The market is consequently responding to the restrictions imposed by the COVID-19 pandemic by raising prices. The results obtained open up new lines for research, in particular the impact of the COVID-19 pandemic on the supply and demand structure on the world commodity markets.
