Alterations to the bending mechanical properties of Pinus sylvestris timber according to flatwise and edgewise directions and knot position in the cross-section
Authors: Fernández-Serrano Álvaro , Villasante Antonio
Published: July 2024

Given the heterogeneity of the material, the behaviour of a timber beam may differ depending on which of its sides is subjected to tension and which one is subjected to compression. An analysis is undertaken in the present work of the behaviour in non-destructive bending tests on the four sides of 57 samples of Pinus sylvestris (scots pine) of structural size (2000 × 100 × 70 mm3). A study is additionally performed of the influence of the size and position of knots in the cross-section. The modulus of elasticity in flatwise direction was found to be 3 % higher than in edgewise direction. This difference could be attributable to the shear effect. While the introduction of knottiness variables did not improve modulus of elasticity prediction, it did decrease the error in the prediction of the modulus of rupture. The margin knot area ratio corresponding to the outer eighth of the cross-section’s width occupied by knots was the knottiness variable with the lowest error in modulus of rupture prediction.

The article examines the conditions limiting the discretionary powers of courts in the civil process. The problem is established of the applicability by courts of prejudicial facts contained in judicial acts in a previously considered case in a new trial if they do not correspond to the internal convictions of the court. The relevance of the work lies in the special significance of the institution of prejudicial facts in the context of implementing legal certainty of the entire legal system of Russia. The purpose of the study is to analyze the current legislation of Russia in order to determine the essence of prejudicial facts as conditions limiting the activities of courts in the civil process in Russia. The subject of the study is the norms of procedural legislation regulating the application of prejudicial facts by courts, as well as the judicial practice of higher courts. By analyzing the norms of Russian legislation, it is concluded that prejudicial facts require a more detailed settlement, in particular, on issues related to the basis for releasing the court from the obligation to take into account the circumstances established in the course of a previously considered case.

Authors: Дмитрий Александрович Фомин ,   Южно-Российский институт управления – филиал Российской академии народного хозяйства и государственной службы при Президенте РФ, Ростов-на-Дону, Россия
Published: July 2024

The article proposes a conceptual model of political investment of business, which reflects the political and economic realities of the modern Russian state. In the conditions of unprecedented external pressure on the national economy, political investment by representatives of business circles at the federal and regional levels is one of the effective tools that contribute to the strengthening of internal dialog between society and government represented by public institutions. Also, political investment provides an increase in stability and investment attractiveness of the economy as a whole, reduces the riskiness and corruption component. The author of the article proposes as an initial theoretical and methodological platform for the meaningful disclosure of political investment as a category of political science analysis the classical concept of corporation, which is historically linked to the concept of civil society. The central idea that political investment expresses is the mediation of private and public interests.

Authors: Sullivan Erika A. , Jordanova Kayla , Curtin Andrew D. , Frame Kara A. , Hall Scott , Kiraly Bernadette , Taylor Eliza , Stoesser Kirsten
Published: July 2024

Background and Objectives: Learning to provide long-acting reversible contraception (LARC) during family medicine residency is an important step in building capacity for the primary care workforce to meet the reproductive health care needs of communities. We aimed to measure the impact of adding a contraceptive visit type (CVT) allowing for rapid access to contraception (RAC) on family medicine resident LARC procedure numbers.
Methods: Our program created a CVT in which patients were seen only for contraceptive services. We added the CVT to third-year family medicine resident continuity clinic schedules and a block of CVTs (the RAC clinic) to the third-year gynecology rotation. Residents self-reported LARC procedure numbers performed throughout residency, and the totals were compared for graduating residents from 2023 (post-RAC cohort) to 2022 graduates and 2018–2022 graduates (pre-RAC cohort).
Results: Post-RAC cohort residents reported a statistically significant increase in intrauterine device (IUD; P=.015) and contraceptive implant (P=.010) removals compared to the 2022 pre-RAC cohort. Insertions of IUDs and contraceptive implants were unchanged when compared to the pre-RAC cohort. IUD removals (P=.004) and insertions (P=.034), and contraceptive implant removals (P=.028) were significantly increased for post-RAC compared to 2022 graduates, with no difference in contraceptive implant insertions (P=.211).
Conclusions: The addition of the CVT and RAC clinic contributed to an increase in LARC removals in both comparisons, and IUD insertions between 2022 and 2023. This clinic model offers an opportunity for other family medicine residency programs to improve access to contraceptive services and increase resident training in LARC management.

Published: July 2024

Penelitian ini dilatarbelakangi oleh terbatasnya hasil riset yang menunjukkan literasi emosi peserta didik. Oleh karena itu, dalam penelitian ini tujuannya difokuskan untuk menggambarkan bagaimana literasi emosi peserta didik terkait aspek mengetahui perasaan diri. Penelitian ini menggunakan pendekatan kualitatif dengan metode classroom ethnography. Partisipan penelitian ini adalah peserta didik dan guru di salah satu SD. Teknik pengumpulan data dilakukan melalui observasi, wawancara dan dokumentasi. Analisis data penelitian ini didasarkan pada teori literasi emosi oleh Steiner, terdapat tiga tahapan, yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa peserta didik mengetahui emosi tertentu sesuai dengan yang dirasakannya, tetapi tidak mengetahui bagaimana mengungkapkannya supaya tidak berdampak negatif terhadap kualitas hidupnya dan orang lain; selain itu sejumlah besar peserta didik sudah mengetahui alasan emosi yang merasa rasakan, tetapi beberapa peserta didik cenderung mengekspresikan emosi tersebut secara spontan dengan cara negatif melalui ekspresi wajah dan gestur tubuh seperti menunjukkan tatapan sinis, dahi mengerut disertai wajah memerah, nafas menderu, menghindar dan menendang meja. Dapat disimpulkan bahwa literasi emosi peserta didik utamanya pada aspek mengetahui perasaan diri masih belum memadai.Â  Dengan demikian, edukasi literasi emosi bagi peserta didik SD dipandang penting untuk mulai diterapkan sedini mungkin melalui lembaga pendidikan formal utamanya dalam KBM.

Del mito oral al audiovisual
Authors: Grünig Ana Karen
Published: July 2024

En un contexto global signado por la hegemonía de la comunicación neoliberal, en Argentina se desarrollaron, durante los años 2010-2014, una decena de concursos públicos de fomento a la producción de contenidos audiovisuales regionales que buscaban democratizar, descentralizar y diversificar el espacio audiovisual nacional históricamente dominado por las lógicas del mercado y la centralización en la capital, Buenos Aires. Una de las vías de fomento de mayor impacto por su carácter inédito, fueron las series de ficción federal, de las cuales, las mitologías populares resultaron ser una de las temáticas de mayor recurrencia. En este marco, nos interrogamos sobre los procesos de transposición de mitologías populares hacia las series audiovisuales regionales, advirtiendo que, más allá de su capacidad de espectacularización, constituyen experiencias de las identidades narrativas, regionales y subalternas. En ese sentido, entonces, procuramos comprender el entramado de significaciones políticas que subyacen en dichos procedimientos. Concretamente, de un corpus de diez series audiovisuales, en este artículo exponemos el análisis hermenéutico interpretativo de la ficción salteña El aparecido (2010), que narra la creencia popular sobre el mito de “El Familiar” a partir de la creación de una nueva mitología que re-significa la cultura pertenencia. Metodológicamente, desarrollamos un análisis de la transposición a partir de tres operaciones previas: el reconocimiento del contexto de producción de la serie, el análisis de la serie propiamente dicho, y la realización de entrevistas a sus autores.
O cinema de Larissa Sansour e a solução de um Estado no conflito Israel-Palestina
Authors: Gomes Barbosa Karina , Castro Rodrigo
Published: July 2024

Este artigo busca compreender como a cineasta palestina Larissa Sansour mobiliza a luta anticolonialista palestina contra a ocupação sionista através da análise fílmica de Patrimônio Nacional (2013). Além de refletir a respeito das interações entre as imagens do filme dentro da própria narrativa, relacionamos a obra com as categorias violência, território, temporalidade e vestígios; entrevistas da cineasta sobre seu trabalho e a situação da Palestina; e com os recentes acontecimentos pós 7 de outubro de 2023. Além disso, investigamos como Sansour se apropria do gênero da ficção científica e seus tropos, como elementos constitutivos para criar um filme-manifesto baseado nas teorias decoloniais de autores como Achille Mbembe (2018), Ilan Pappé (2016) e Edward Said (2012), tensionando os conceitos e apontamentos deles junto à narrativa fílmica, principalmente os que se referem aos efeitos prolongados de processos de colonização como o estabelecido por Israel na Palestina desde 1948. Mais do que refletir sobre a colonização, entendemos que Larissa Sansour, através de Patrimonio Nacional, se estabelece como uma força anticolonial, endereçando uma contundente crítica ao sionismo e aos empreendimentos capitalistas que acompanham processos de colonialidade como este.

Published: July 2024

A partir de uma análise de textos, entrevistas e filmes dos cineastas Arthur Omar e Trinh T. Minh-ha, buscaremos compreender as convergências e divergências entre seus modos de pensar a representação fílmica do “real”, em especial em seus modos de questionamento da linguagem documental clássica hegemônica. Os trabalhos de Didi-Huberman (2014, 2015) e Shohat e Stam (2006) nos ajudarão a contextualizar as relações entre colonialismo, imperialismo e eurocentrismo no cinema, estabelecendo as problemáticas a respeito das quais Omar e Minh-ha irão se dedicar em seus trabalhos.
As brancas nuvens não se desmancham no ar
Authors: Gregório Santos Taynara , Távora Bruna
Published: July 2024

O livro apresenta o conceito de colonialismo digital em uma dupla dimensão: subjetiva e objetiva. Subjetiva, pois, ao abordar o aspecto da subsunção formal dos processos de produção e consumo, destacam que a cognição, o conhecimento e o comportamento social se constituem pela mediação de algoritmos racistas, presentes na totalidade das relações sociais. Objetiva, porque mostram que esse processo depende da exploração de recursos naturais presentes em territórios do Sul Global, o que reatualiza o racismo e a racialização. Escrito com a experiência da educação popular dos autores, o livro flui com uma clareza que facilita sua compreensão. Ao combinar conceitos do materialismo histórico e dialético e da literatura anticolonial, o estudo oferece uma ampla e rica discussão a respeito do colonialismo digital e como podemos enfrentá-lo.
O porão do mundo

Published: July 2024

Compondo uma espécie de nova trilogia que revê a anterior das “cartas das Fontaínhas”, Juventude em Marcha (2006), Cavalo Dinheiro (2014) e Vitalina Varela (2019) de Pedro Costa ampliam seu foco no bairro marginal da periferia de Lisboa para as experiências da diáspora cabo-verdiana residente em Portugal e para a sua existência fraturada no tempo e no espaço, marcada pela emigração forçada, pela discriminação e pelo abandono. Mas, em vez de trabalhar essas vidas negadas apenas como material narrativo, os filmes de Costa também as incorporam na forma composicional. A natureza não consecutiva dos planos, a utilização do claro-escuro e dos limiares que fazem do invisível parte constitutiva do enquadramento e a rarefação da fala (quase sempre sob a forma de monólogos) são apenas alguns dos modos como o cinema de Costa ecoa a experiência de vida de suas personagens na própria estrutura do filme. Neste artigo, proponho que essa matriz composicional também alude (embora de forma não referencial) à dimensão histórica e geopolítica do Atlântico luso como origem do Plantationoceno colonial-moderno e do seu correlato contemporâneo, o “devir-Negro do mundo” (Mbembe, 2014).
Um épico de terror no cinema contemporâneo
Authors: Comar Freza Luis Guilherme
Published: July 2024

Este ensaio apresenta uma leitura crítica do filme The Northman (2022) considerando as características próprias de seu gênero (épico) no cinema e maneiras de redefinir seus códigos, bem como os diálogos estabelecidos com ele, conforme propomos que o filme de Robert Eggers realiza através da construção de uma atmosfera de terror. Consideramos também o diálogo com a história da dramaturgia como maneira de contribuir para essa atmosfera pela exploração de algumas figuras e momentos característicos do pathos aterrorizante no drama (do período grego clássico a Shakespeare), ao mesmo tempo em que os velhos arquétipos são desafiados a novos desenvolvimentos de lugares de significação diferenciados para os personagens.
Case study at esp classes as mode of language adaptation to future engineering profession

Published: July 2024

In the current era of rapid modern society growth and Ukraine’s integration into the European community, professional proficiency in English is a prerequisite for engineering personnel. This suggests that the national higher education system needs to meet new standards and that student’s personal and professional qualities are essential. In this regard, it is crucial to realize that, to properly train future engineers, English language programs must imitate the most scommon professional scenarios to establish environments that are similar to those of professional foreign language communication. All of this is made feasible by employing the case study approach in English language lessons as a replicated model of an engineer’s professional activities. The article aims to investigate and bolster the advantages of the case study approach for engineering students learning ESP. The experiment involved 82 engineering majors from the Podillia State University (Ukraine) who had finished the compulsory Business English course in the academic year 2022–2023. The respondents were divided into two groups: the first group learned languages using the conventional way, and the second group employed the case study approach. The data were confirmed using statistical calculation methods (namely the p-value). The experiment results support the theory that the case study methodology is a better approach to learning a foreign language than the conventional approach. The study findings show how useful the case study approach was, assuming both professional language proficiency and immersion in real-world language contexts.

Published: July 2024

Biomass energy is an important area of renewable energy. However, the efficient use of raw biomass for energy purposes does not always have the desired effect, so there is a need for biomass processing. One of the ways to improve the fuel characteristics of biomass is its torrefaction. Torrefaction allows to obtain fuel with a high energy density, which in energy terms will be close to coal. This retains most of the benefits of burning biomass over fossil fuels. There is no universal way to determine the optimal modes of heat treatment of biomass, so the study of effective methods and parameters of torrefaction for individual crops continues today. This paper investigates the influence of different regimes of heat treatment of Miscanthus Giganteus biomass on the fuel characteristics of the torrefied product and the changes that occur in the biomass. The research was conducted at the research facility for torrefaction in the educational and scientific laboratory “DAK GPS” of the higher educational institution “Podillia State University”. The method of heat treatment in a static layer was used, which eliminates the influence of side factors on the process of torrefaction. Regularities between the initial parameters of raw biomass, selected modes of torrefaction and the characteristics of the final product are established. The results of these studies will allow to develop a system of recommendations for optimally balanced and energy efficient production of torrefied product from biomass of Miscanthus Giganteus. The research has established that the optimal temperature for torrefaction of Miscanthus Giganteus biomass can be considered 250-300 ºC.

Published: July 2024

The current problem of implementing European approaches to safety and health at work in Ukraine must take into account certain differences in the national occupational safety and health (OSH) legislation and the realities of its compliance at various enterprises. The purpose of this research is to characterize the main strategic directions of OSH activities in Ukraine on the basis of a comparative analysis of statistical indicators of occupational injuries in the EU countries and in Ukraine. A system-wide approach was applied, based on the methodology of statistical analysis of indicators of industrial injuries. This made it possible to substantiate the investigated structure and relationships of the OSH system. The analysis of the coefficients calculated as the ratio of the total number of injured workers to the number of deaths at work showed that the trend of increasing this coefficient during the previous ten years is characteristic of EU countries, in contrast to Ukraine, where this coefficient decreased by 40%. It is shown that for the introduction of European approaches to OSH strategy in Ukraine, it is necessary to take into account the existing differences in approaches to assessing the statistics of industrial injuries and occupational morbidity. Based on the statistical analysis of the data of the State Labour Service of Ukraine, three main causes of industrial injuries were identified, the total share of which reaches 80% of the total number of causes used in the state statistics of industrial injuries, which corresponds to the Pareto principle. As part of the OSH system in agricultural enterprises of Ukraine, potential occupational risks during the performance of mechanized works were determined according to the method of expert assessments, analyzed and systematized according to their categories - high, medium, low.

Published: July 2024

The modern post-industrial stage of development of the market economy is characterized by the gradual transition of market power from producers of products or services to consumers. Under such conditions, the struggle for the customer forces logistics companies to increase the level of logistics service and develop strategies based on a compromise between the costs associated with the provision of logistics services and the level of logistics service provided to customers. In this regard, there is a need to develop adequate methods and approaches to assessing the required level of logistics service and its impact on the achievement of the company’s strategic goals. The study discloses organizational and methodological approaches to the development of a logistics service system based on a set of target indicators (key indicators for evaluating logistics service) aimed at achieving the selected strategic task of the company’s logistics. Methods of economic, statistical, and mathematical modeling, and system analysis were used as research tools. The paper proposes a methodology for the formation of a logistics service system, built by the MAI method within the framework of the general policy of the company for logistic customer service. Its approbation of the example of the company “Sfera-Avto” showed that the chosen operational policy in the field of customer service, taking into account the most significant alternatives, corresponds to the chosen strategic objective of the company’s logistics, namely “minimization of the cycle of the fulfillment of customer orders”. The choice made is reflected in the company’s logistics from the strategic level (building a strategic map of the logistics department and forming a balanced system of logistics indicators) to the operational level (performing logistics operations within the framework of implemented business processes).
Effect of steam injection on performance and emissions of agricultural diesel engine
Authors: Amatnieks Karlis , Birkavs Aivars
Published: July 2024

The need to reduce vehicle emissions has encouraged the development of various solutions. One of them is the steam injection method, which proved to be an effective option of reducing NOx emissions. In order to evaluate the effectiveness of the steam injection method on an agricultural engine, appropriate tests were carried out at the Alternative Fuels Research Laboratory of the Latvia University of Life Sciences and Technologies. The engine KDI 1903M and a self-made steam device ensuring steam injection in the intake manifold were used in the tests. The research engine was connected to the SIERRA CP-Engineering engine test bench. Additionally, emissions were recorded by the AVL SESAM FTIR exhaust gas analytical system. Testing was performed without steam supply and with steam supply at constant speeds, as well as in different load modes - 10 kW and 20 kW. The results showed that the largest reduction of nitrogen oxide (NOx) emissions was obtained at idling (7.5%), while in case of all load modes the results were very similar (reduction by 4.1-5.0%). At the same time, increase of carbon monoxide (CO) emissions was observed in all testing modes by 3.0-5.6%, while carbon dioxide (CO2) changes were negligible. The studies confirmed an insignificant increase in the power and torque. The results prove that further research should increase the volume of steam supply by improving the given device.
Research in processes and machines for local strip application of moisture-holding organic fertilizers

Published: July 2024

In Ukraine’s territories, there is a potential for rapid growth in organic agricultural production, not only for the domestic market but also for the global market. However, achieving this requires a shift in plant production technologies and ensuring the production of necessary agricultural machinery to facilitate specific technological operations. Global climate change necessitates alterations in regional crop rotations due to reduced plant productivity, especially during the germination stage, where moisture requirements fluctuate. Conversely, the pursuit of maximum yields has led to intensified use of mineral fertilizers, contributing to ecological degradation and decreased soil fertility. Maintaining the balance of nutrients in the soil can be achieved by regular local application of moisture-retaining organic fertilizers in the range of 10-12 tons per hectare. These fertilizers should be derived from organic raw materials possessing a well-developed colloidal structure capable of gradual moisture accumulation and release. Proposed components for producing these fertilizers include sapropel with natural moisture content sourced from freshwater reservoirs. This study presents laboratory and field research results from experimental plots cultivating potatoes, vegetables and soybean, affirming the effectiveness of the proposed technology. The article also describes the construction of machines for local application of moisture-retaining organic fertilizers. A theoretical study of the interaction of organic fertilizer particles with the working body of such machines is presented, and the dimensions and rotation speed are substantiated.

Thermal insulation of pipelines finds application across various industries, including agricultural technologies. The energy efficiency hinges on minimizing heat losses. The task is primarily achieved through effective heat insulation. Decentralized ventilation systems prove to be efficient in rural low-rise constructions. Among these, regenerative ventilators like Blauberg Vento/Vents TwinFresh stand out. There exists a goal to enhance their operational efficiency, which involves ongoing investigation into heat recovery processes within their thin ducts. Improving the insulation of the experimental setup leads to a reduction in experimental uncertainty. Also, a new gas exchange camera for CO₂ exchange in plants requires very low uncertainty of airflow measurements requiring very high precision of air density measurement. However, heat losses can influence the air temperature deviation in a flow meter. However, within the realm of heat transfer literature, the concept of the critical insulation radius is stated. Increasing the insulation radius beyond a certain point might diminish its efficacy due to outer surface development. Theoretical assumptions posit a constant heat transfer coefficient for the outer surface. Previously, we analysed the critical radius of horizontal cylinder pipes. This study deals with laminar convective flow around the outer vertical cylindrical insulation surface. Employing a formula considering the Grashof number, the average heat transfer coefficient is analysed. The results indicate that increasing insulation thickness reduces the surface temperature and the heat transfer coefficient such as for vertical pipes. An analysis of the thermal resistance function concerning the ratio of outer to inner diameters, and its derivative, was conducted. The asymptotic increase in the thermal resistance was found. This fully disproves the critical radius concept opening new perspectives on energy efficiency and thermotechnical research precision.
Small shipment sustainable deliveries within and between cities

The paper deals with small shipment delivery-planning problems either within cities or between cities. The small shipment delivery planning is a corner stone for forwarders, couriers, express-mail companies, retailers, wholesalers and other companies, which are responsible for delivery processes. It is significant to plan the delivery by optimal way, reducing both rates – time and cost of delivery. It is important to satisfy customers’ needs simultaneously. Pendulum route planning is the main problem for small cargo delivery planning between cities. It is necessary to choose the best transport mode combination, the most appropriated hub, the best route and the best forwarding company. Small shipment delivery planning in cities has another problem. Despite of the smaller transportation distance, it often takes more than half into total delivery costs. Smaller vehicles are used in transportation within cities. Hard intensity of traffic, great number of customers and cargo loading circumstances make the delivery problem more difficult. Managers have to plan efficient transportations. The author of the paper recommends analyzing the specification of demand at first to choose the most appropriated strategy of delivery. It is expedient to divide the route into separated blocks; picking out the main mode of transport, the best hubs into the route as well as last 500 kilometer problems of delivery (FHD problem – the main novelty of the paper) planning. Then it is necessary to find the solution for the last 50 kilometer delivery and, finally, to solve the last mile delivery problem.
Tightness monitoring camera for critical parts of rural technological and scientific equipment

There are a lot of devices, including rural equipment with a high level of tightness. Nowadays, a wide range of methods are used for investigation and testing: capillary, radiographic, radio wave, mass spectrometric, eddy current, surface-active substances, etc. These methods require special equipment and do not allow continuous monitoring during operation. The traditional soap solution coating can continuously monitor the tightness until drying. Thus, there is a problem in creating an easy and robust method of monitoring the tightness of the critical equipment parts during the operation. In this work, a new method for the tightness control is proposed. It is based on the principle of distributing flows in parallel piping. If the camera around a critical part is sealed, its leaks will have high aerodynamic resistance. Therefore, if a small hole (0.1-1 mm) is made in such a camera, its aerodynamic resistance will be some order smaller. Since the distribution of flows is inversely proportional to the square of the specific characteristic of aerodynamic resistance, the main outflow or inflow due to leakages in the critical part inside the camera will occur almost through this hole, which is easy to register. This camera has been used in the Laboratory of Heat-Mass Exchange in Green Structures to test gas exchange in plants. For testing the method, the fan in the test stand before final sealing is slowly accelerated until the signal appears. After that, the flow rate has been estimated using a collector. The results show a very high sensitivity. In the collector, the anemometer showed only 0.02 m·s-1. The confidence interval of the flow is 0-0.019 m3·h-1. However, the anemometer reading near the hole is 0.43, which is a very clear signal. The signal will be clear at the leakage of 0.0086 m3·h-1. The soap coating of all junctures and smoke visualisation did not show a leakage place. This allows recommending the camera for the most critical equipment parts.
Modelling of demand shock impact in food sector on sectoral development: case of Latvia
Authors: Auzina-Emsina Astra , Auzins Alberts
Published: July 2024

In order to promptly model the cross-sectoral impact of the market crisis (macro-level impact in the narrow sense) that primarily has a direct impact on agriculture and food production, but due to the cross-sectoral linkages, the full impact also includes the impact on other sectors and the overall impact on the economy (macro level in the broadest sense), the input-output modelling tool is used. Two scenarios have been modelled: the effect of external shocks on the demand for products from the agricultural and food production sectors. Latvian farmers, producers and consumers are mostly price takers, therefore the changes in the global price level largely determine the price level in the domestic market. The modelling of the first scenario which involves a decline of food industry exports by 40%, assuming that household consumption remains at its previous level and is not initially affected and replaced by cheaper imported food industry goods, results in the net final consumption expenditures on food products decrease by 30.1%, resulting in a 25.1% drop in food industry output, also affecting the output of agriculture (-8.3%) and fishing (-10.9%). The impact on other sectors is relatively minor. The total net final consumption declined by 1.8%, but the domestic output -2.5%. Modelling the second shock scenario with two sub-scenarios the product market is experiencing a shock and export demand is declining by 50%. Modelling results show that agriculture itself has the most significant impact due to a decrease in the net final consumption expenditure by 44.2%, while agricultural output by 28.1%. The food production output declined by 0.8%, the total output – by 1.9%, and the total value-added – by 1.4%. The use of the input-output approach is directly linked to the available data on agricultural subsectors and their linkage with all other sectors of the economy.
