Published: May 2024

Black soybean grain (Glycine max L. Merril.) storage is susceptible to insect pests such as Callosobruchus analis (F.), which feeds on soybeans. Steroids/triterpenoids, phenolics, alkaloids, tannins, and terpenoids found in moringa leaf powder can be employed as insect repellents in black soybean grain warehouses. The purpose of this study was to ascertain how applying plant-based insecticides made from powdered moringa leaf will affect the amount of C. analis (F.) that died, the severity of the damage, and the weight loss of black soybean seeds of the Detam 4 Prida varieties. The study took place from August to October 2019 at an elevation of 878 meters above sea level in the Biology Laboratorium of the Agriculture Faculty, University of Winaya Mukti. An experimental design including five treatments and five replications was employed as the research methodology. A was not given any moringa leaf powder; B, C, D, and E each received 0.25, 0.75, and 1 grams of moringa leaf powder, fine powder, and so on. 10 pairs of C. analis (F) per jar were used in each treatment, which involved 100 g of black soybean grain. In the storage of black soybean grain, the percentage of seed damage, weight loss, the number of eggs, larvae, pupae, and images, and mortality of C. analis (F) were all impacted by 0.75 g of moringa leaf powder, according to the findings. According to this research, C. analysis, a warehouse insect pest, is effectively repelled by powdered moringa leaf (F.).

Brass material is important for all industrial parts. Brass had good ability work in cold or hot conditions, in solid state CuZn is capable of dissolving more crystals in the mixture. At temperatures of 902°C peritectic transformation occurred where Zn soluble in 32.5%. Solubility is increased up to a temperature of about 450 ° C to 39% and then in equilibrium will decrease, the length of the heating and cooling process is very long. With descriptive technique showed that the weld strength brass highest (7863.1 kgf / mm2) is that the surface of the specimen suffered welding rubbing with a gap distance of 0.2 and 0.3 mm, both with water cooling or air cooling, and the condition other relatively much lower strength (3144.89 kgf / mm2). Welding the workpiece surface is not polished strength is low. Specifically, properties - mechanical properties of brass can be improved by the addition of small amounts of other alloying elements without reducing the characteristics of the brass in general. But with a maximum limit zinc levels should not exceed 42% because it will result in a brass are fragile because of excess levels of zinc, and cannot be used commercially. with the addition of other elements as reinforcing elements of brass such as silicon, bismuth, selenium and others to improve the ability of the brass in the machining process. Welding results by using three different types of welding wire shows that, at the time of welding is performed with brass welding wire in the market there is no trouble found. Welding speed specimen is also calculated using a stopwatch, and the speed required for welding in 3 specimens, the average in the first specimen takes 5 minutes for the welding process. And the visual results produced is also satisfied.

Authors: M. Taufik Ilham , Prasetyaningsih Endang , P. A. Hidayat Nita
Published: May 2024

A downtime will decrease machine availability that will affect reliability and maintainability. If interval time between two consecutive machine failures is approach to zero, it shows that the machine reliability is low, and so the availability. In the other hand, if interval time between is high, the machine availability and reliability are high. However, the procuring cost of the machine components is expensive. The problem is what is the maintenance interval time in order to optimize machine availability and reliability. In this study, the downtime is minimized by determining maintenance intervals using a multicriteria, i.e. reliability, availability, and maintainability (RAM). The model used in this research is the Age Replacement Model. A case study of a cement company is taken to show the determination of the maintenance interval. The observation shows that the Kiln Division has the longest total downtime of 1,846 hours/year although the Kiln Division has implemented overhaul during 15 days and maintenance one times. The total downtime of the Kiln Division was caused by failure to the Grate Cooler machine by 56.582%.  A maintenance interval is proposed, and the result shows that the proposed maintenance intervals reduce total downtime by 86.6% and improve machine availability by 1,8%.

HISTORICAL TOPONYMY AND TOPOGRAPHY OF THE VILLAGE OF LITYNIA (15th – early 19th centuries)
Authors: HALIV Mykola
Published: May 2024

The purpose of the article is to present the results of research into the historical topography and toponymy of the village of Litynia in Drohobych county. The studyis based on the compilation of manuscript and published sources of the XV – early XIX centuries. The research methodology is based on the principles of scientifi city, systematicity, general scientifi c (analysis, synthesis) and special-historical (historical-typological, historical-systemic, historical-comparative) methods, as well as methods of criticism of historical sources. The scientifi c novelty is that for the fi rst time in historical science, the historical topography and toponymy of the village of Litynia (Drohobytch district, Lviv oblast), has been analyzed. Conclusions. So, in the historical and linguistic literature, there are three main versions of the origin of the name of the village of Litynia: 1) from the words “lito” (summer), “lituvaty” (spend the summer); 2) from the root “lut” – swamp (swampy area); 3) from the anthroponym Lit (Lita). Nevertheless, we give preference to the fi rst and not only because of its historical primacy, but also because it is based on folk tales, whichactually formed the basis of the statement of a well-known local historian of the second half of the 19th century Ludwik Dziеdzicki. The village of Litynia appeared on the banks of the Trudnytsia River, which was vital for the economic and domestic functioning of the settlement. The topographical features of Litynia and its surroundings have undergone certain changes over the centuries. Already in the 16th century. the settlement of Silechka, which was probably located in the town of Sredniy Horb, disappeared, the germ of the village of Grud may have appeared. Until the XVIII century the thickets and forests surrounding Litynia from the north and south were cut down. The toponymy of Litynia, of course, needs a more thorough onomastic study, but it is mostly connected with the peculiarities of the locallandscape, soils and fi elds, and their use by the peasants.
Key words: toponymy, topography, oikonymy, historical local history, Litynia,Drohobych county, historical sources.
MYKHAILO HRUSHEVSKY IN THE CIRCLE OF SCANDINAVIAN SLAVICISTS: COOPERATION AND RECEPTION

Published: May 2024

The purpose of the research – the scientifi c novelty of the research consists in a comprehensive attempt to comprehensively analyze the multifaceted relations of M. Hrushevsky with his Scandinavian colleagues during the end of the 19th – the fi rst third of the 20th centuries. The research methodology relies on the use of an interdisciplinary approach. Based on the principles of objectivity and historicism, the research has d the structuralfunctional systematic analysis of historiographical facts and the comparative-historical method. The article has used the heuristic possibilities of periodisation, classifi cation and typology methods. The scientifi c novelty of the research consists in a comprehensive attempt to comprehensively analyze the multifaceted relations of M. Hrushevsky with his Scandinavian colleagues during the end of the 19th – the fi rst third of the 20th centuries Conclusions. In conclusion, we would like to note that Ukrainian intellectuals, as well as M. Hrushevsky, had almost the most harmonious relations with their Scandinavian colleagues. After all, unlike, say, Polish and Russian scientists, they were not divided by the complex issues of the common past and the often tragic circumstances of the revolutionary era. Thus, fruitful scientifi c relations were established between Ukrainian and Scandinavian Slavists, which had benefi cial consequences for both sides. The most important achievement of the time was the involvement of Scandinavian colleagues in the study of Ukrainian historiographicaland linguistic issues. Studying it from the standpoint of Ukrainian cultural interest, they popularized the vision of our history and spiritual heritage as unique civilizational phenomena. In addition, the relationship led to mutual scientifi c reception, which contributed to the intellectual rapprochement of East Slavic and Scandinavian cultures. As a result, thanks to M. Hrushevsky and his colleagues, an important international dialogue was started, which is still the foundation of the Ukrainian-Scandinavian partnership. Finally, we consider the attempted reconstruction of M. Hrushevsky’s cooperation with his Swedish and Norwegian colleagues to be only the fi rst step in the direction of clarifying a larger problem, which can be described as “Ukrainian and Scandinavian science in mutual infl uences and representations”.
THE RECEPTION OF THE CIVILIZATION IMAGE OF THE “WEST” IN THE HISTORIOGRAPHIC HERITAGE OF VLADYMYR ANTONOVYCH
Authors: KUTSYI Ivan
Published: May 2024

The purpose of the study is to investigate the perception of the image of the “West” in the civilizational views and ideas of Volodymyr Antonovych in the general context of the genesis of the Ukrainian civilizational thought of the 19th century. The research methodology is primarily based on the principles of historicism, systematicity, scientificity, objectivity, as well as the use of general scientific (analysis, synthesis, generalization) and special-historical (historical-genetic, historical-typological, historical-systemic) methods. The scientific novelty lies primarily in the fact that for the first time we approach the problem of Volodymyr Antonovych's ideas about the “West” as a separate, self-sufficient problem. The article offers a clear vision of the civilizational views and ideas of this scientist.  Conclusions. The article examines the views of the scientist on the issue of penetration of European influences into Ukraine.Volodymyr Antonovych’s contribution to the change in the Ukrainian intellectuals’ Slavic identity into European has been investigated. From this point of view, the main research papers and journalistic works by Volodymyr Antonovych on historical topics have been analyzed. Special attention has been paid to V. Antonovych’s diligent desire to conceal his views on civilizational identity. Therefore, a significant place in the source base of the study is occupied by the memories of students and contemporaries about the historian’s views on the European factor. Also, an important role in the article has been given to the analysis of V. Antonovych’s correspondence with his friends. As there wasn’t any cencorship in the letters, the scientist far more openly disclosed his views on the civilizational affiliation of Ukraine here, than in published scientific works or other public texts. The article proves the leading role of  V. Antonovych in the process of introducing European identity to Ukrainian historians. This result has been achieved by the historian, not by directly proving the thesis of Ukraine’s European identity on the pages of historical works, but in the course of private communication with the trusted circle of his colleagues, students and followers. V. Antonovych was the first in Ukrainian historiography to overcome most Slavophile prejudices against the West and tolerantly interpreted Western European influences on the phenomena in Ukrainian history. The transition of V. Antonovych to European identity did not mean complete abandonment of Slavic identity: he considered the Slavic to be an integral part of the European tradition. It has been found that the historian unequally treated different constituents of Europe. He was especially revered by the Roman peoples (especially France), and he had considerable prejudices against the Germans.
ISSUES OF INTERNATIONAL RELATIONS IN THE LEGACY OF YULIAN TARNOVYCH AS THE EDITOR OF “NASH LEMKО”
Authors: NAKONECHNYI Volodymyr
Published: May 2024

The purpose of the article is to investigate the peculiarities of Y. Tarnovych’s articulation of the multi-layered subject of international relations in the columns of the newspaper “Nash Lemko”. The research methodology is based on the combination of principles (historicism and objectivity) and methods (philosophical, general scientific and special-historical) of scientific research, which are usual for works on the historical science. The scientific novelty of the article consists in an attempt to comprehensive reconstruction of Y. Tarnovych's journalism on the pages of “Nash Lemko”, dedicated to the relations of Ukrainians with Poles, Russians and Jews. Conclusions. Summarizing the journalistic work of Y. Tarnovych devoted to the problems of international relations presented on the pages of “Nash Lemko”, it was noted that its content was determined by life itself. After all, in his daily life, the Ruthenian was often frustrated by the aggressive national and fiscal policy of the Polish state, Russian agitators with Bolshevik and Muscophile slogans, as well as the desire for unjust profit from Jewish innkeepers and resellers. All this prompted the editor of the first Ruthenian newspaper to intensify reflection on difficult relations with neighbors from a historical perspective and in the reality of the time he lived in. The consequences of such reflection for Y. Tarnovych was teaching Lemko readers to resist to the manipulations of uninvited guests. In some places, as it was in the Jewish case, such advice was influenced by the xenophobia prevalent on the eve of the Second World War and harmed the Ruthenians themselves in their attempts to find a model of possible harmonious inter-ethnic coexistence with neighbors. However, in general, the journalistic work of the editor of “Nash Lemko” contributed to the establishment of the Sobornost ideology and values of public activism in the Ruthenian environment. This helped the Lemkos to acquire the necessary unity and stability in times of military confrontation, to quickly self-organize after being expelled from their native lands, and to build an equal dialogue with representatives of different peoples in their new countries of residence.
Key words: Y. Tarnovych, international relations, journalism, “Our Lemko”, the Second Polish Republic.
Relevance of transformative evaluation paradigm in monitoring and evaluating ethnic profiling prevention interventions: A case of Kenya National Cohesion and Integration Policy
Authors: Abuya Isaac , Odero Peter Otieno
Published: May 2024

Increased discriminatory ethnic profiling has been observed in Kenya based on factors such as race, ethnicity, religion, gender, sexual orientation, socioeconomic status, age, and disability. This has led to social inequalities, especially for the marginalized and minorities who lack a voice to stand up for their rights. This research paper is aimed at improving the Kenya National Cohesion and Integration Policy, by application of a transformative paradigm in addressing ethnic diversities. The transformative paradigm as observed from different kinds of literature encompasses all measures of difference, including sex, gender, age, nationality, race, and religion that point to reducing ethnic profiling. Against this backdrop, this study seeks to borrow the paradigm assumptions and philosophical thoughts in dealing with people who have experienced discrimination and oppression. It also lends itself to evaluating interventions around ethnic profiling. The study was guided by three objectives; To review the theoretical and empirical literature on the relevance of the transformative paradigm in monitoring and evaluation of (1) inclusion, (2) participation, and (3) ethnic diversity. Desktop search and a Google scholar search engine were used to review theoretical and empirical literature. Purposive sampling was adopted in the selection of suitable literature for the study. Results of the study suggested that monitoring and evaluation of KNCIP can be used in improving ethnic diversity by borrowing philosophical assumptions and thoughts from the transformative paradigm. Inclusion, participation, and peaceful coexistence are the core theme in the transformative paradigm that culminate in social cohesion and reduces ethnic profiling regardless of a social setup's cultural or socioeconomic status. Recommendations to the study include; conducting an empirical study on the relevance of transformative paradigm in promoting social cohesion, requesting the government of Kenya to support advancements in technology that promote social justice, encouraging policy influencers to participate in policy developments actively, and offering capacity building and training in matters social cohesion, to relevant stakeholders in the society.
Inclusiveness and Social Justice in Evaluation: An Evaluability Assessment
Authors: Maliah Gatdet Gabriel Matut , Abuya Isaac Odhiambo
Published: May 2024

Kenya is a multi-ethnic and culturally diverse society that has witnessed conflicts arising from this ethnic and cultural diversity. The country’s politics is tainted with ethnic sentiments and politically induced disharmony. This paper used evaluability assessment to determine whether two issues identified in the Kenyan Cohesion and Integration Policy as threats to building a unified nation are evaluable, feasible and of use to achieve the policy’s objectives. The feasibility study, better known as an evaluability assessment, confirms that these two issues can be evaluated and can help policymakers and practitioners to achieve the country’s dream of building one cohesive nation that is proud of its diversity. Based on the discussion in this paper, it is advised that Kenya uses the evaluability assessment to provide short-and long-term outcomes that might be examined to measure efficacy and save superfluous or poorly conceived full-scale evaluations. The evaluability assessment method could be used in other, well-established programs related to the Kenya National and Integration Policy with a variety of stakeholders to foster new thinking and the potential for more focused and effective evaluations, even though there may be variations between programs and it is still unclear how generalisable these results may be. The next step would be to continue with an evaluation based on the results of this evaluability assessment and to continue refining the logic model with input from the participants.
Examining the Correlation and Predictive Power of Metacognitive Domains on Mathematics Performance Among Senior High School Students
Authors: Catador Jose
Published: May 2024

This study aims to determine the correlation and predictors of students’ performance in mathematics based on the eight domains of metacognition: declarative, procedural, conditional, planning, information management strategy, comprehension monitoring, debugging strategy, and evaluation. This study employed a descriptive-correlational research design conducted with 272 Senior High School Grade 11 students enrolled in the academic track. The research instruments utilized were the Metacognitive Awareness Inventory to assess students’ metacognitive awareness while the multiple-choice test was used to measure students’ performance in mathematics, with reliability coefficients of .853 and .790, respectively. Descriptive and inferential statistics, such as Chi-square and multiple regression analysis, were employed to interpret and analyze the data. Utilizing the descriptive statistics, results reported that metacognitive knowledge attained a mean score of 3.69 while the metacognitive control/regulation obtained a mean score of 3.65 with an overall mean score of 3.67 interpreted as aware, respectively. Furthermore, the results revealed a significant association between students’ performance in mathematics and their metacognitive awareness. The study highlighted that high-performing students in mathematics were those who effectively utilized and managed their metacognitive awareness. Moreover, it was found that greater awareness of metacognitive thinking correlated with better performance in mathematics. Additionally, the results indicated that 75.3% of metacognitive domains contributed to students’ success in mathematics. However, only declarative, procedural, conditional, and debugging strategies significantly predicted students’ success in mathematics. This suggests that students who effectively use and manage these specific metacognitive skills are more likely to excel in mathematics. In essence, this study highlights the crucial role of metacognition in mathematics learning. By fostering students’ awareness and utilization of these powerful thinking strategies, teachers can empower learners to excel in mathematics and beyond.
Linear support for the prime number sequence and the first and second Hardy-Littlewood conjectures
Authors: Aslaksen Helmer , Kirfel Christoph
Published: May 2024

Servais and Grün used results about linear support for the prime number sequence to obtain upper bounds on the smallest prime in odd perfect numbers. This was extended by Cohen and Hendy who proved that for every $n \in \mathbb {N}$ there exists an integer $b_n$ such that $p_i \ge p_1 + ni - b_n$ for any sequence $(p_i)$ of odd primes, and found minimal values of $b_n$ for $3 \le n \le 5$, and conjectured minimal values for $6 \le n \le 10$. We give a new proof of the existence of $b_n$ and the values for $3 \le n \le 5$. We also show that if we assume that the second Hardy-Littlewood conjecture, $\pi (a+b) \le \pi (a) + \pi (b)$ for $a, b \ge 2$, is true, then we can in a finite number of steps determine numbers, $T_n$, that give quite close bounds for the values of $b_n$, namely $T_n \le b_n \le T_n + n - 2$, and determine the values of $T_n$ for $6 \le n \le 20$.
We also consider the question of whether the values of $b_n$ can be replaced by smaller numbers if we assume that $p_1 > 3$. We will show that if we assume that the first Hardy-Littlewood conjecture is true, then we can determine the minimum such values, $a_n$, for $3 \le n \le 5$. We also determine some lower bounds for $a_n$ for $n \ge 6$. It is well-known that the two Hardy-Littlewood conjectures are mutually exclusive, but we never use both conjectures simultaneously.
These results give us the upper bound $p_1<\frac {n}{2^n-1}t+b_n$ on the smallest prime in odd perfect numbers, where $t$ is the number of distinct primes dividing the odd perfect number. This bound was also found by Cohen and Hendy, but we improve the constants $b_n$.

With the rising cooling demand and prevalent energy crisis, District cooling (DC) is evolving as one of the sustainable energy solution worldwide. As per ‘EHP DHC Outlook, May 2023’, the sales in DC sector reached 3 TWh, covering more than 150 European cities. The centralised nature of the DC system offer benefits such as energy efficient operations, sector coupling, peak load management. Further, the feasibility of integrating renewable technologies (eg. solar energy), free cooling sources (eg. seawater heatpumps) and thermal energy storage (eg. ice slurry) is also explored. These developments make the futuristic DC system quite complex, as it involves multiple energy transformations. In this regard, utilising computation tools for decision-making has become increasingly relevant. However, choosing the appropriate approach among the existing ones in this evolving field is a curb some task for energy practitioners. The aim of the study is to review the modelling and optimisation approaches in the context of innovative DC systems. Data collection and analysis is based on desk-review of scientific literature published in the recent past. Firstly, various possibilities of integrating sustainable energy technologies for DC applications are explored. Then, relevant modelling and simulation approaches are studied, focussing on the similarities and limitations. Finally, different optimisation methods are examined in terms of parameters such as objective functions, control variables, solving techniques. The contribution of the study involve overview of different integration pathways, identifying the strength and weakness of modelling approaches and insights into suitability of optimisation techniques. It is expected that this study will be a reference material, while performing feasibility studies as well as developing digital-twins in DC context.
Integrating Low Temperature Waste Heat in District Heating Systems. Legal Framework and Pricing Mechanisms
Authors: Zirne Marita Agate , Pakere Ieva
Published: May 2024

ABSTRACT:Decarbonisation the heating sector is a key challenge for the European Union to achieve its ambitious goals of becoming the first climate - neutral continent in 2050. Decarbonising the heating sector is about reducing fossil fuel consumption and finding new scenarios based on renewables and restructuring the operation of district heating system. Recovering and integration waste heat into the district heating system has an enormous potential to meet the heating needs of households through non – combustion technologies while reducing carbon emissions. The heat from urban sources of waste heat is advantageous because the heat sources are, close to district heating networks and close to areas with high heat demand. However, there is still no legal or regulatory framework for the use of waste heat and no incentives for its use in district heating in the Member States of EU.This paper has two main objectives: firstly, to consider different pricing and cost determination scenarios when the waste heat is integrated into the district heating system. The heat tariff calculation model is based on the approved Latvian heat tariff calculation methodology. Secondly – to consider a mathematical model for the pricing of waste heat. The waste heat integration strategies are tested on the Case study of district heating system in Salaspils, Latvia. Simplified model of a waste heat recovery system that recovers heat energy from a wastewater treatment plant through heat pump integration is developed.

While the rapidly growing global population will require a significant increase in food production in the next years, the current climate, sanitary and geopolitical crises highlight the weaknesses of the actual food production systems, excessively dependent on external inputs and involving extremely complex nested scales and non-linear processes. Thus, appears clearly the need of accelerating the transition toward agricultural solutions and food systems based on the principles of the “Green Deal”, encompassing ecological resilience, environmental sustainability, local production, and universal access to healthy foods. Aquaponics (AP) can provide short and eco-friendly food supply chains with increased resource-use efficiency, high environmental sustainability, and food resilience. The sustainability of AP systems could be further increased by exploiting water resources that are not suitable for other purposes (brackish and salt water - haloponics), applying the vertical farming technology for both aquatic and vegetable species, reducing the use of fish meal in aquafeeds, valorizing the system residues (sludge) for agronomic purposes.The VERTICHALPONICS project aims to develop an innovative food production system by implementing an interdisciplinary approach. Since aquaponics combines recirculation aquaculture and hydroponics, within a close loop, it is considered environment friendly. However, given the different technical approaches, it is necessary to evaluate the differences in impacts and specially to assess whether the vertical system is really resource-efficient and economically viable for farmers, in comparison to the business-as-usual. The environmental and economic sustainability of the system is measured by the mean of a combined LCA and the LCC analysis (EN ISO 14040-44 and ISO 15686-5:2017 standards). The system expansion will be used to evaluate the beneficial effect of reducing the overall environmental burden from by-product recovery and utilization of side wastes, specifically the sludge produced. The method applied are Recipe and IPCC 2013 Global Warming Potential 100a. Environmental impact indicators will be provided using both mid-point and end-point categories thank to the Recipe Method, while the IPCC 2013 Global Warming Potential 100a will be applied to calculate the direct global warming potential of the system. Moreover, the inclusion of the agronomic valorization of the sludge will be analyzed to understand the potential in terms of avoided impacts.

Published: May 2024

In the context of the European Green Deal and rapid climate change, significant changes in people's habits are necessary, transforming their behavior from resource consumers to climate-responsible individuals. Addressing challenges such as biodiversity loss, engagement in the development of a circular economy, responsible energy consumption, and resource sharing requires changes in individuals' attitudes and behaviors. However, individuals often lack understanding of the climate system, its link to quality of life, and the impact of actions based on individual interests on societal transformation processes as a whole. Governments and international organizations implement various complex measures, but the dynamics of climate change far exceed society's ability to adapt.To address these challenges, the authors of this paper propose using simulation games as an effective learning method. These games provide individuals with an opportunity to gain a new, community-oriented decision-making experience without creating negative effects on real systems due to inappropriate decisions. Simulation games help to better understand cause-and-effect relationships, factors influencing individual attitudes and behaviors, evaluate the consequences of decisions made, and motivate practical involvement in mitigating climate change. In order to improve the attractiveness of using the simulation game, cultural and creative industry competences are integrated, which contribute to the improvement of content, visualization and interaction.The paper examines an organizational model for simulation games that assists municipalities and other stakeholders in developing customized simulation games to promote the development of climate-responsible communities. Considering the necessity to engage diverse social groups with varying levels of digital skills, an analog format has been chosen for the simulation game, without excluding the possibility of transforming it into a digital one.The proposed model includes setting objectives, integrating elements into a holistic simulation game, and piloting the framework using examples from municipal practice. To optimize the applicability of simulation games, they need to be adapted to the geographic area and community due to individual processes and structures.

Considering the hazardous future scenarios outlined for the environment by the scientific community and various institutions, embracing more sustainable production methodologies is imperative. This is especially vital within the construction and energy sectors, which stand as significant contributors to climate change and environmental impact.  The topic presented herein aligns with this direction. Specifically, the aim of this study is to highlight the benefits of transforming conventional agriculture into a technologically advanced and environmentally sustainable practice. The proposed study demonstrates new ways of using reeds (Arundo Donax, L.) in two strategic sectors - i.e., building and heating fuel - promoting the reduction of environmental impacts compared to traditional materials. The study explored the utilization of reeds as a material for roofing or wall coverings and as pellets for heating stoves. A Life Cycle Assessment was performed to investigate environmental impacts in all the phases of the processes. In the first case (i.e., reeds used in the building sector), a reduction of environmental impacts within the construction phase was found, followed by an enhancement of performance in the buildings on which the reed panels were installed. In fact, they contribute to minimizing heat losses, leading to a subsequent decrease in fuel consumption for heating and cooling, and help to mitigate acoustic problems. In the second scenario (i.e., reeds used as heating fuel), the goal of the study was to detect if Arundo Donax was suitable for pellet production. In this instance, all the production processes were analyzed (e.g., harvesting, shredding, drying, pelletizing) together with the intrinsic characteristics of the pellets (e.g., calorific power, content of carbon, etc.). This analysis enabled the evaluation of substituting traditional materials with reeds.
Remote Solar Parks for Building Decarbonisation: A Lithuanian Case Study on Virtual Prosumers
Authors: Grinevičiūtė Monika , Valančius Kęstutis
Published: May 2024

To reduce the carbon footprint of buildings, the concept of virtual prosumers (consumers who both consume and produce) using remote solar energy parks represents a novel method in Europe. In 2019, Lithuania became the first country in Europe to introduce a digital platform that enables the buying or renting of parts of a remote solar park, making it the first such platform in the world to operate on a national scale. This study examines the effectiveness of this model in Lithuania, assessing the model's success, public engagement, and success factors. The main study focus is on evaluating the impact of remote solar parks on the decarbonization of buildings, particularly through the prism of virtual prosumer participation.Applying a mixed research method, this study integrates both qualitative and quantitative data. The quantitative analysis includes a detailed case study, evaluating the amount of energy produced by two selected remote solar parks in Lithuania, as well as their impact on the carbon dioxide emissions and primary energy use of the two individual houses (a detached house and a unit within an apartment building) connected to these remote power plants. Concurrently, qualitative methods involve analyzing the existing legal and economic frameworks in Lithuania and Europe, which either facilitate or impede the prosumer model, in addition to examining the necessary technological infrastructure.Key findings of this study highlight the potential of remote solar energy parks to significantly reduce the carbon emissions of buildings. This model is especially beneficial for structures where onsite solar energy solutions are impractical. It fosters greater inclusivity in adopting renewable energy, enabling a variety of stakeholders to participate in and benefit from clean energy production. However, the study identifies several major challenges, including regulatory restrictions, the need for infrastructure development, a shortage of developers, state contributions, public awareness, and the creation of a unified platform.
