Published: January 2025

The deficit and dependence on imported energy resources, mineral fertilizers, their price growth, negative changes in climatic conditions, pollution of water resources, air and soil, withdrawal of a largepart of agricultural land due to hostilities affect the functioning of the agricultural sector. This creates threats to ensure food, energy and environmental security of Ukraine. As part of the implementation ofthe Sustainable Development Strategy in Ukraine, which is based on ensuring national interests and fulfilling international obligations, it is envisaged to overcome the imbalances that exist in particular inthe environmental sphere, to harmonize global climate change trends with international standards. The priority is land resources, agriculture, forestry, water resources, bioenergy, biodiversity. The scientificarticle examines the provision of rational use of natural resources thanks to effective waste management. The concept of a resource-saving agro-industrial complex was formed due to the development and 29 implementation of bio-organic technologies for growing agricultural crops for the production of biofuels from agro-biomass and animal husbandry waste. The agro-technological aspects of ensuring the energy independence of the industry and the formation of the country's food security have been proven. The main areas of effective use of agrobiomass and utilization of agricultural waste for the production of biofuels have been determined. On the basis of the researched state of supply of energy resources of the agricultural industry and assessment of the available potential of the industry in agrobiomass, the theoretical volumes of biofuel production to ensure the energy independence of the industry are calculated. A comprehensive analysis of the European experience in the production of biogas from crop and livestock waste and the use of digestate obtained on the basis of anaerobic fermentation in a biogas plant has been developed. The purpose of the study is to establish agro-technological aspects of digestate production, taking into account the international experience of adaptation to climate change in order to guarantee the reduction of the impact of the degradation processes of the soil cover of Ukraine. The subject of research is global climate change, land resources, agriculture, forestry, waterresources, bioenergy and biodiversity. The research methodology is based on experimental studies of scientific topics on the topic: «Development of bio-organic technologies for growing agricultural crops for the production of biofuels and ensuring the energy independence of the agricultural sector».

Published: January 2025

This paper discusses two projects that revolve around the conceptualization of tourism products within the framework of interpreting and understanding archaeological sites through a sustainable approach as part of TURARQ's initiative. The primary objective was to explore the application of a co-creation model, specifically the Project Based Learning methodology of "Demola" with the support of the "Link me Up" project, in the field of archaeological tourism.

The first project, Show Me the Past, involved the development of a mobile app that utilized an agile requirement analysis to create a prototype. The second project, Showcasing Prehistory, focused on entrepreneurship, inclusion, heritage, and sustainability, using a diagnosis of the social issues affecting the Mação territory. The outcomes of the first project included the creation of a Mobile Augmented Reality (MAR) application, which allows users to visualize virtual objects in the real environment of discovery. In the second project, empathy maps were developed, encompassing archaeotourism, the local community, theme parks, and special needs. The findings indicated that these programs generated high levels of participant satisfaction and positively impacted competency development. However, further studies are required to ascertain the number of participants who have transitioned into entrepreneurs because of their involvement in these projects.
Dinâmica de adoção da economia circular ao nível regional: o papel dos governos regionais e das camaras municipais
Authors: Almeida António , Machado Luiz , Jacob Marta , Florido Cármen , Rodriguez Carlos 
Published: January 2025

A economia circular (EC) surge como um tópico mediático, mobilizador e apelativo para múltiplos stakeholders, dado o consenso existente à volta da problemática da sustentabilidade e das alterações climáticas. Contudo, as decisões empresariais nesta área revestem-se ainda de um carácter voluntário, numa série de áreas e medidas. A relevância estratégica do setor turístico n, assente numa dinâmica de colaborações e de sub-contratação de serviços, sugere que o mesmo pode desempenhar o papel de role-model, no sentido da adoção generalizada da EC, desde que salvaguardada uma intervenção por parte dos governos regionais e locais. Com base numa amostra de 90 estabelecimentos hoteleiros da Grã-Canária e da Madeira, são identificados os fatores explicativos da taxa de adoção de medidas em quatro sub-áreas distintas de forma a identificar áreas de relevo para a intervenção por parte da administração pública. Os resultados destacam o papel do grau de comprometimento por parte dos diretores hoteleiros, e das barreiras percecionadas e do acesso a recursos disponibilizados pelas autarquias, o que releva o papel das Camaras Municipais e dos governos regionais. Identicamente importante os fatores estatisticamente insignificantes, nomeadamente a ausência de pressão por parte de clientes e fornecedores.
Interprosthetic Joint Motion in Bipolar Partial Hip Arthroplasty After One-Year Follow-up
Authors: Yeo Noreen Joyce , Leagogo Liberato Antonio 
Published: January 2025

Background: Partial hip arthroplasty is the treatment of choice for displaced femoral fractures in the elderly. The bipolar prosthesis was developed to lessen the acetabular erosion encountered with the unipolar prosthesis. However, bipolar prostheses lose their motion between the inner or outer articulation (interprosthetic joint motion) after three months, rendering them biomechanically like unipolar prostheses. Literature has shown that the interprosthetic joint is mobile radiographically up to one year after the surgery.
Objective: This study evaluated and quantified the interprosthetic joint motion (motion between the outer and inner articulations) of bipolar prostheses one year after partial hip arthroplasty for proximal femoral fractures in a tertiary hospital. We also investigated the effect of adding the hip measurement in adduction.
Methodology: This retrospective cohort study measured the motion of the outer and inner articulations of locally available bipolar prostheses and the interprosthetic joint movement using one-year postoperative radiographs of patients who underwent bipolar partial hip arthroplasty for femoral fractures in a tertiary hospital from 2019 to 2021. Immediate and one-year post-operative AP radiographs in neutral, maximum hip abduction, and maximum hip adduction were measured and compared. The interprosthetic joint motion was calculated from the difference in pelvic-head angles and pelvic-shaft angles.
Results: Twelve patients were included in the study. The interprosthetic joint in bipolar prosthesis was still mobile even after one year in 75% of patients (p = 0.0001). Adding hip adduction measurements resulted in a significantly higher mean of 74.69 degrees as compared to only 34.67 degrees (p = 0.0006).
Conclusion: Most patients retained a mobile interprosthetic joint at one year post-op. Hip adduction radiographs gave additional information on the total interprosthetic joint motion. At both time points studied, the inner head articulation contributed more to the interprosthetic joint motion. All five local implant systems used showed good motion after one year.

Published: January 2025

Статья вводит в научный оборот материалы, полученные в 2022 г. при раскопках выявленного многослойного поселения Вознесенское IV, находящегося в окрýге Галичского озера. В раскопах найдены фрагменты фатьяновской, фатьяноидной посуды, сетчатая керамика с фатьяноидными традициями. В финале эпохи бронзы – начале раннего железного века преобладает бедно орнаментированная (в основном ямками) сетчатая керамика с рябчатым мелкоячеистым отпечатком, распространяется подштрихованная посуда, орнаментированная ямками или тычками. Поселение имеет важное научное значение, отражает процесс формирования комплексов сетчатой керамики до ананьинского расселения на берегах Верхней Волги, начало которого происходит в VI в. до н. э. С поздним этапом раннего железного века и ранним Средневековьем связаны индивидуальные предметы и керамические комплексы. Заключительный этап освоения площадки поселения приходится на XIII–XV вв. н. э.
The article introduces into scientific circulation the materials obtained in 2022 during the excavations of the revealed multilayer settlement Voznesenskoye IV, located in the district of Galichskoye Lake. Fragments of Fatyanovo, Fatyanoid ware, mesh ceramics with Fatyanoid traditions were found in the excavations. In the Bronze finale – the beginning of the Early Iron Age, poorly ornamented (mainly with pits) mesh ceramics with a pockmarked fine-meshed imprint prevails, shaded ceramics ornamented with pits or pokes are distributed. The settlement is of great importance and reflects the process of formation of complexes of mesh ceramics before the Ananyinsky settlement on the banks of the Upper Volga, which began in the VI century BC. Individual objects and ceramic complexes are associated with the late stage of the Iron Age and the early Middle Ages. The final stage of development of the settlement site coincides with the XIII–XV centuries AD.

Aim: To evaluate the in vivo anti-inflammatory activity of the essential oil and fatty acid compositions of the volatile oil of Raphia australis fruit pulp.
Method: The oils of pulp and seed of Raphia australis were isolated using Clevenger apparatus and were further subjected to GC-MS analyses. Anti-inflammatory test was carried out on the pulp of Raphia australis oils using four groups of rats comprising six rats per group (n=5). Group one were administered normal saline (0.09 % v/v NaCl) while group 1, 2 and 3 were administered 40 mg kg-1(volatile oil), 80 mg kg-1 (volatile oil) and 100mg kg-1 aspirin, respectively. Inflammation was induced in all the groups using lipopolysaccharide.
Results: From the GCMS analysis, 20 compounds were detected in the oil of R. australis pulp while 19 compounds were shown to be present in the seed oil. The total fatty acid content of R. australis seed oil was 38.1 %. The rest were essential oil compounds (21.6 %). There are 6.6% unknown compounds present in the oil obtained from the seed of R. australis. The essential oil content of the pulp of R. australis was 68.6 %. The pulp contained 16 % of fatty acids with 9.1 % unknown compounds. The limonene content (38.4 %) of Raphia australis pulp was found to be about 6 times higher than that of the seed (6.3 %). However, the quantity of hexadecenoic acid obtained from the seed (34.4 %) was more than 3 times higher than the amount found in the pulp (10.8%). Other volatile compounds present in the pulp include 2-pentylfuran (3.2 %), germacrene D (7.1 %), nonanal (3.3 %) alpha cadinene (5.2 %), tertradecanoic acid (2.2 %) while nonanal (8.5 %), eicosane (3.9 %) b-pinene (2.2%), 2 pentyl furan (1.9%) and tetradecanoic acid (1.7 %) constitute the major component of the rest of the volatile oil of the seed of Raphia australis. The result of inflammatory activity of the volatile oil of Raphia australis pulp using adult male mice showed that 80 mg kg-1 dose of the oil elicited a significant anti-inflammatory effect (P<0.01) when compared to 100mg kg-1 of aspirin (P<0.01). The analgesic activities of aspirin (P<0.05) and the 80 mg kg-1 dose (P<0.05) of the oil were only significant in the inflammatory phase of the analgesic test.
Conclusion: These results show that the volatile oil of Raphia australis has therapeutic potential for use in the management of inflammation-related disorders.

Authors: C J Uzodike, , N Brambaifa, , I Ogbuehi, 
Published: January 2025

Aims: Plant antioxidants are considered safe, nutritional, and therapeutic, offering promising solutions to oxidative stress-related health issues. This study explores the antioxidant potential of column fractions derived from the methanol extract of Abrus precatorius, a plant with limited prior evaluation of its bioactive fractions.
Study Design: The study used an experimental design.
Place and Duration of Study: Orlu LGA, Imo State, Nigeria
Methodology: Plant materials were collected from Orlu LGA, Imo State, Nigeria. The dried, powdered leaves were screened for phytochemical constituents using standard methods. Methanol extract was obtained through cold maceration and further fractionated using column chromatography packed with silica gel (60–120 mesh), with elution performed using a gradient mixture of hexane, ethyl acetate, and methanol. The phytochemical analysis confirmed the presence of alkaloids, flavonoids, tannins, cardenolides, and saponins, compounds known for their antioxidative properties. Column chromatography yielded five fractions (F1–F5), which were assessed for antioxidant activity using both in vivo (rat models) and in vitro methods, including 2,2-diphenyl-1-picryl hydrazyl (DPPH) and nitric oxide assays.
Results: Notably, fraction F1 demonstrated a significant increase in glutathione and catalase activity, while F4 showed a marked elevation in superoxide dismutase activity in erythrocytes. In liver tissue, F1 and F5 showed exceptional catalase activity, with respective increases of 258 % and 290 %. Fraction F3 exhibited a 290 % increase in superoxide dismutase activity. Furthermore, F3 effectively reduced DPPH radical activity with an IC50 of 0.2 mg/mL, while F4 significantly lowered nitric oxide levels with an IC50 of 0.3 mg/ml.
Conclusion: This study highlights the novel identification of potent antioxidant fractions from Abrus precatorius methanol extract, offering valuable insights for developing plant-based therapies for oxidative stress-related disorders such as cardiovascular diseases, diabetes, and neurodegenerative conditions. It underscores the plant's potential as a safe, natural antioxidant source for further pharmacological exploration.
