Abstract. Hilmi E, Hendrayana, Samudra SR, Fikriyya N, Junaidi T, Cahyo TN, Putri NA, Ummah AN. 2024. Species-specific and landscape carbon storage analysis of mangrove forest in Segara Anakan Lagoon, Cilacap, Central Java, Indonesia. Biodiversitas 25: 2748-2755. Mangrove forests are one of the world's largest carbon pools. However, each mangrove species has a different capacity to sequester and store carbon in its biomass. Therefore, at the landscape scale, there are also differences in carbon storage and percent carbon between habitat sites influenced by dominant species and stand density due to differences in environmental conditions. This study aims to analyze each mangrove species' percent carbon and carbon storage and develop a mangrove landscape in Segara Anakan Lagoon, Cilacap District, Central Java Province, Indonesia. This study used destructive methods to collect mangrove samples. The percentage of carbon of each species was analyzed using a formulation of volatile and ash values, while carbon stock for each species was estimated using allometric equations. Landscape analysis of carbon stocks was based on mangrove stand density. The results showed that the carbon percentage of mangrove species averaged between 42.48-53.34% with Rhizophora spp. (R. apiculata, R. mucronata and R. stylosa) and Bruguiera gymnorrhiza having the highest carbon percentage of 47.1-55.6%, followed by Sonneratia spp. and Avicennia with 43.0-48.6%, Ceriops spp., Aegiceras spp., Heritiera littoralis and Xylocarpus spp. with 43.0-48.2%, and Nypa fruticans had the lowest carbon percentage with 39.1-41.0%. At the landscape scale, Segara Anakan had mangrove biomass between 34.83-786.61 tons/ha with carbon stock between 7.85-186.09 tons C/ha. Based on percent carbon, the mangrove landscape in Segara Anakan was dominated by B. gymnorrhiza, R. apiculata, R. stylosa, Ceriops tagal, and R. mucronata. Avicennia marina, Aegiceras corniculatum, N. fruticans, R. apiculata, and Sonneratia alba dominated mangrove landscapes based on carbon storage. The results of this study indicate that carbon storage in mangrove ecosystems is important to support carbon conservation because it has a high percentage of carbon and large carbon storage.

Abstract. Habibah NA, Yuniastuti A, Susanti R, Lisdiana, Mustikaningtyas D, Lutfiah A, Aulia SN, Rabbani T. 2024. Growth and production of secondary metabolites in the callus of Bima Brebes shallot varieties. Biodiversitas 25: 2811-2820. Shallots contain bioactive compounds that can be produced through callus culture. This study investigates the effects of growth regulators 2,4-D, picloram, and kinetin on the growth and production of secondary metabolites in shallot bulb callus. A Complete Randomized Design (CRD) with two factors was used in the experiment. The first factor was the concentrations of 2,4-D (0, 1, 2, and 3 ppm) and picloram (0, 1, 2, and 3 ppm). The second factor was kinetin concentrations (0, 0.25, and 0.5 ppm). The parameters evaluated were callus fresh weight, callus dry weight, percentage of callus formation, callus induction time, callus morphology, phytochemical components, and antioxidant activity. The optimal growth medium is crucial for developing growth curves. Bioactive compounds were identified using Liquid Chromatography-Mass Spectrometry (LC-MS). Results indicated that explants grown on a medium combining picloram and kinetin exhibited better growth than those grown on a 2,4-D and kinetin combination. The callus colors varied from white to yellowish-white, yellow, and brownish-yellow, with a crumbly texture. Callus from all treatments contained bioactive compounds indicated by antioxidant activity, flavonoid content, and total phenolics. LC-MS analysis identified 87 types of secondary metabolite compounds. Callus treated with picloram and kinetin consistently produced flavonoids and phenolics and exhibited antioxidant activity.

Abstract. Nur M, Tenriware, Utami S, Nasyrah AFA, Sapri R. 2024. Reproductive biology of skipjack tuna Katsuwonus pelamis in Majene Waters, West Sulawesi Province, Indonesia. Biodiversitas 25: 2828-2835. Skipjack tuna Katsuwonus pelamis (Linnaeus, 1758) is a major global fishery resource and a target species in West Sulawesi Province. Therefore, this research aimed to examine various biological factors related to skipjack tuna, including sex ratio, Gonad Maturity Stage (GMS), Gonadosomatic Index (GSI), size at first maturity, and fecundity. The primary objective was to provide essential data that supported the sustainable management of skipjack tuna in Majene Waters located in West Sulawesi, Indonesia. Fish samples were collected by fishermen using purse seine fishing gear and hand lines, and landed at Fish Landing Sites Majene. This research was carried out from July to February 2024, with analysis performed at the Fisheries Department Laboratory, Universitas Sulawesi Barat. The analysis stages included measuring fish total body length with an accuracy of 0.1 mm and weighing the body weight using a digital scale with an accuracy of 0.01 g. A total of 340 skipjack tuna were sampled, consisting of 192 males and 148 females, indicating a nearly balanced sex ratio. The spawning season appeared to extend throughout the year, with a peak spawning period from November to February. This analysis result found five levels of gonad maturity, including GMS I (immature), GMS II (maturing), GMS III (mature), and GMS IV (ripe and running), as well as GMS V (spent). The size at first maturity for males skipjack tuna was 400.2 mm, ranging from 386.6-402.3 mm. Meanwhile, the size at first maturity for females varied between 396.6 and 462.3 mm, averaging 420.2 mm. The reproductive potential of skipjack tuna was relatively high, with an average fecundity ranging from 203,377-739,820 eggs.

Abstract. Gustiar F, Lakitan B, Muda SA, Ria RP, Simamora IA. 2024. Leaf morphology characterization and propagation of Cnidoscolus aconitifolius (Redonda cultivar) using different stem cutting lengths in the tropical ecosystem. Biodiversitas 25: 2836-2844. Chaya (Cnidoscolus aconitifolius (Mill.) I.M.Johnst.) is a kind of perennial vegetable known to originate from Mexico and thrive in the tropical climate of Asia, with different leaf morphology as well as several cultivars, including Redonda cv. Therefore, this study aims to assess the leaf morphology of Chaya Redonda cv. and its growth on different stem cutting lengths of 20 cm, 25 cm, and 30 cm, respectively. All treatments were repeated four times and each replication contained five plant units, while collected data included characteristics in the form of leaf length and width, area, growth rate, and yield. Based on observation through a dimensional method, the Chaya Redonda cv. leaf had a square size with the bottom and top width identical to the ratio value of length and width consistently approaching 1.0 and remaining constant across the development process. The results showed that leaf length (L2) x bottom width (W1) regression had the highest accuracy level for determining ??undamaged chaya leaf area with a coefficient of determination (R2) value of 0.9839. The potential of cuttings with a length of 30 cm was confirmed to have high growth capacity, which also produced a positive effect on leaf number and area, as well as canopy area and fresh leaf weight.

Abstract. Danilova AN, Vdovina TA, Isakova EA, Kotukhov YA, Sumbembayev AA. 2024. Ecological conditions of growth and breeding analysis of Viburnum opulus L. populations in the Kazakhstan part of the Altai Mountains. Biodiversitas 25: 2845-2857. The purpose of this paper was to study the ecological growth conditions of Viburnum opulus populations and the variability of the main morphological parameters of the vegetative and generative spheres of the species at the interpopulation level in the Kazakhstan part of the Altai Mountains as a future promising donor for breeding work. As a result of field research, using route-reconnaissance, traditional geobotanical, and morphometric methods, 24 isolated locations of V. opulus were discovered in the Kazakhstan Altai in the geographical areas of Kalbinsky, Western, and Southern Altai. These areas' ecological conditions of the species growth were studied for the first time, based on which the characteristics of plant communities with the participation of V. opulus were compiled. It was found that the species grows mainly in three types of associations: tree-shrub, shrub-meadow in the forest zone, and steppe shrub-meadow in the mountain-steppe zone. Plant communities with the participation of V. opulus occupy areas on the northwestern and southeastern mountain slopes associated with river valleys. The vertical range of distribution of the species varies from 395 to 913 masl. The total area of the territory occupied by plant communities with the participation of V. opulus was 198.85 ha. Furthermore, when studying interpopulation variability in 9 populations isolated from each other and located in different ecological and geographical growing conditions, 3 main groups of characteristics were identified depending on the degree of variability. High variability was revealed in the height of the shrubs, fruits in the cluster and their weight, the color of ripe berries, taste indicators for fruit bitterness from 1 to 4 points, and yield. Promising populations regarding productivity were identified in Kalbinsky, Western, and Southern Altai, depending on the ecological and geographical growth in the Kazakhstan Altai.

Abstract. Rahmi HA, Syukur M, Sukma D, Aisyah SI. 2024. Diversity of quantitative, qualitative, and vitamin C content characteristics in F5 generation of chili pepper Capsicum baccatum species. Biodiversitas 25: 2878-2886. Chili is a popular vegetable worldwide, and Indonesia is one of the largest chili producers. However, the cultivation of Capsicum baccatum species is still uncommon in Indonesia. This study aimed to assess the diversity and heritability of yield and yield quality of F5 populations of C. baccatum. This study was conducted at the Experimental Field of Perumahan Alam Sinar Sari, Bogor. The experiment followed a randomized complete block design (RCBD) using 12 genotypes with three replications and four sample plants per replication. The F5 populations of the following genotypes were used: 4k-6p, 4k-7p, 7m-4q, 2m-2m, 7m-3q, 7m-3m, 7m-2q, 2m-2q, 7m-8m, 7m-1m, Bishop Crown, and Lemon Drop. The observations included quantitative, qualitative character,vitamin C contents, and soluble solids. The results showed that the fruit weight per plant ranged from 37.73 to 94.24 grams, while the number of fruits per plant ranged from 11.46 to 30.95. Fruit length ranged from 2.65 to 6.08 cm, and fruit diameter ranged from 15.70 to 41.43 mm. The weight per fruit ranged from 3.43 to 14.89 grams. Brightness or L* values ranged from 19.06 to 41.93, a* values ranged from 5.62 to 31.49, and b* values ranged from 22.90 to 57.45. The chroma value ranged from 30.87 to 64.20, and the hue value ranged from 46.54 to 80.23. The analysis of vitamin C content showed a range of 12.20 to 17.74 mg/20 g, and the test results of soluble solids ranged from 8.77% to 13.49%. All quantitative characters showed high heritability, indicating a strong genetic influence on these characters. The qualitative observations were analyzed, and the results showed that the 12 C. baccatum chilies had similarity coefficients ranging from 0.0 to 0.5. The similarity analysis resulted in grouping the 12 genotypes of C. baccatum into four main groups.

Abstract. Puspitarini RD, Purwantoro A, Pradifta VDA, Muhammad FN, Fernando I. 2024. Abundance of arthropod pests and their natural enemies on cassava fields implementing different agroecosystem management. Biodiversitas 25: 2901-2907. Arthropod pests pose significant challenges to cassava (Manihot esculenta Crantz) cultivation, with detrimental effects on yield and crop quality. Agroecosystem management plays a crucial role in shaping the populations of pests and their natural enemies. Therefore, understanding and implementing appropriate management practices are essential for developing integrated pest management approaches that are effective and environmentally friendly. Our study examined herbivorous and predatory arthropod abundance across six cassava plantations with varying management practices. Field characteristics were examined to elucidate the factors contributing to differences in arthropod assemblages observed among the fields. We used Analysis of Variance (ANOVA) to assess the differences in arthropod abundance across the plantations. Additionally, arthropod assemblage was analyzed using analysis of similarity based on the Bray-Curtis Index, with differences visualized using non-metric multidimensional scaling (NMDS) plots. The high abundance of herbivorous arthropods in certain fields appeared linked to narrow plant spacing, which might facilitate pest dispersal. Furthermore, complete weed removal and the absence of organic fertilizer application, such as manure, could reduce predatory arthropod populations. Additionally, fields situated at lower altitudes demonstrated increased susceptibility to pest outbreaks. Therefore, strategic agroecosystem management is imperative, incorporating practices to mitigate pest population growth while conserving predatory arthropods. Comprehending the interplay between management practices and arthropod dynamics is crucial for developing sustainable pest management strategies in cassava cultivation.

Abstract. Nurmiati N, Herwina H, Periadnadi P, Janra MN, Hidayat R, Edelwis TW. 2024. Exploration of natural microflora from stingless bee honey harvested from Limau Manis area, Padang, West Sumatra, Indonesia. Biodiversitas 25: 2908-2916. The natural microflora in stingless bee honey has been explored in three stingless bee species: Tetragonula laeviceps Smith, 1857; Heterotrigona itama Cockerell, 1918; and Geniotrigona thoracica Smith, 1857. This study aimed to identify and analyze the proportions of natural microflora in stingless bee honey. The study used a survey method, with data being descriptively analyzed and presented. The focus was on identifying microflora groups of bacteria and yeast in the honey from these three stingless bee species. Proteolytic bacteria Microflora types were identified based on the medium used: GPA+CaCO3 for acidic microbes, SMA for proteolytic bacteria, and ethanol+CaCO3 for acetic acid microbes. The pour plate method was used to count the microbes. T. laeviceps honey (pH 3.3, sugar level 45% Brix) contained a total of 163.6×104 CFU/mL microflora (161.6×104 CFU/mL bacteria and 2×104 CFU/mL yeast). In contrast, honey from H. itama (pH 3.4, sugar level 57% Brix) harbored a total of 156.7 x 104 CFU/mL microflora (155.7×104 CFU/mL bacteria and 1×104 CFU/mL yeast) and G. thoracica honey (pH 3.7, sugar level 70% Brix) contained 129.6×104 CFU/mL bacteria only. Acidic (A) and proteolytic (P) bacteria were observed in honey samples from T. laeviceps (A= 69.3×104 CFU/mL; P= 36×104 CFU/mL), G. thoracica (A= 53.6×104 CFU/mL; P= 40×104 CFU/mL), and H. itama (A= 67.0×104 CFU/mL; P= 38.6×104 CFU/mL). Acidic and proteolytic bacteria were present in all three honey samples. In conclusion, the microflora composition in stingless bee honey varies across species, with bacteria being the dominant group in all samples. The pH and sugar content of honey may influence the microbial load, indicating a possible link between honey properties and microbial diversity.

Published: December 2024

The article examines young Europeans’ retrospective accounts of intergenerational caregiving during serial migration. It draws on interviews with 18 young people whose parents moved to Sweden from Poland or Romania before relocating their children. Theoretical lenses of care circulation in transnational families, generalised reciprocity, negotiating caregiving and fostering are applied to analyse three cases, each representing a specific type of care triangle. The first finding from the study is that the young people experienced emotional distress and feelings of abandonment as a result of their parents’ migration. Their stories exhibit resistance and the use of coping mechanisms to handle their feelings. In some cases, geographical distance and living apart weakened the emotional bonds between the parents and their children, whereas other relationships were strengthened. Second, the article shows how the young people engaged in negotiating and bargaining over how to be cared for and fostered. Third, it reveals that intergenerational care continued after the young people’s migration through negotiation of how to practise generalised reciprocity in relationships with parents and co-carers who remained behind in their countries of birth.
Young adults recount their experiences as young carers in Australia: ‘I guess it’s just what I had to do’
Authors: Walker Owen , Moulding Richard , Mason Jonathan
Published: December 2024

Young carers represent a poorly understood subset of Australian youth. Data were collected through semi-structured interviews with 13 young Australian adults who undertook an informal caring role prior to the age of 20. Findings indicate that providing care to a loved one as a child or adolescent is a difficult task that appears highly transformative, with effects that continue into young adulthood. Several common factors were identified, including difficulties engaging with school, feeling under-supported and often experiencing social isolation. Most participants reported a significant impact on their mental health. Counterintuitively, many respondents reported pride and gratefulness for the experience.
Can quasi-cyclical preferences be rational?
Authors: Dohrn Daniel
Published: December 2024

One important dimension in the work of José Luis Bermúdez concerns broadening our ideal of deliberational rationality beyond the narrow confines of standard rational decision theory. In this vein, he (2022) presents two bold claims: (i) there are ‘quasi-cyclical preferences’. (ii) Quasi-cyclical preferences can be rational. These claims contradict received wisdom in decision theory. I shall critically discuss both claims, expressing doubts as to whether there are quasi-cyclical preferences, and whether they can be rational.
The role played by scientific realism in the measurement problem of quantum mechanics
Authors: Manero Orozco Jorge Alberto , Guzmán García Juan Alberto
Published: December 2024

Many attempts have been made to characterise and solve the infamous measurement problem of quantum mechanics by advocating, implicitly or explicitly, different realist perspectives. As a result, we are still uncertain where this problem and its corresponding solution are to be located in the realism-antirealism debate. On the basis of a well-known characterisation of scientific realism, this paper intends to fill this gap by arguing that the quantum description of the processes involved in typical measurements is problematic from the standpoint of semantic realism, which is a necessary but not sufficient condition for fully-fledged scientific realism.
The unfeasibility of onto-representationalism
Authors: Martín-Villuendas Mariano
Published: December 2024

Much effort has been devoted to explaining in what sense models represent their corresponding target systems. This has been considered a pivotal philosophical problem since representational models have been widely assumed to canalize our knowledge and understanding of reality. The aim of the paper is to analytically structure the framework commonly adopted to address the Scientific Representation Problem (SR-P), i.e., onto-representationalism, and to examine its main problems. Due to its very theoretical conditions, I conclude that onto-representationalism constitutes an inadequate meta-scientific platform to approach SR-P. I locate the problem in the semantic assumption. To materialize these analyses, I examine the main arguments proposed by the main variants of onto-representationalism: classical onto-representationalism and sophisticated onto-representationalism.
Why do spacecraft always experience a black-out area that disrupts communications when they return to Earth?
Authors: Wang Jian’an
Published: December 2024

In this paper, Lorentz factor and Lorentz transformations are modified based on the new aether theory, and the blackout which leads to communication interruption of high-speed moving objects is analyzed by using the modified Lorentz electromagnetic field transformation formula. It is concluded that blackout is caused by the change of wave form of electromagnetic wave from stationary energy space (etheric reference frame) to moving medium (etheric reference frame) or from moving medium to stationary energy space.

Avascular osteonecrosis (AON) is a common condition that can occur at any age, but more often in young and able-bodied people. The disease leads to rapid destruction and collapse of the subchondral bone with subsequent formation of secondary osteoarthritis of the affected joint. The review presents modern methods of instrumental diagnostics of AON. Particular attention is paid to the detection of stage I AON. An approach to early diagnosis of AON is discussed that may change the misconception of viewing bone tissue edema as a sign characteristic only of AON and may improve differential diagnosis of the disease from other conditions and treatment outcomes.

Published: December 2024

Identification of the non-radiological stage of axial spondyloarthritis (nr-axSpA) has contributed to the improvement of diagnostics and the expansion of therapeutic approaches in the early stages of the disease. However, there is still an unmet need for effective treatment of patients with active nr-axSpA.

Objective: to evaluate the dynamics of nr-axSpA in patients in the Kaliningrad region and to identify additional factors influencing the radiological progression of the disease.

Material and methods. A total of 68 patients with nr-axSpA were examined at baseline and during 3 year follow-up, most of them were women (62%). The median age of the participants was 27.5 [23.0; 33.3] years. The duration of diagnosis was 1 [1; 2] years. HLA-B27 antigen positivity was present in 40% of cases. Patients at baseline and during follow-up underwent a standard clinical and laboratory examination, pelvic radiography and magnetic resonance imaging of the sacroiliac joints. In addition, cytokine levels (visfatin, PPM1A, MIF, serum calprotectin) and the concentration of IgCD74 antibodies were determined.

Results and discussion. After 3 years of follow-up, the diagnosis still met the criteria for nr-axSpA in 30 (44.1%) of the 68 patients, in 16 (23.5%) it transformed into radiographic axSpA (r-axSpA), in 7 (10.3%) – to axial psoriatic arthritis, in 13 (19.1%) the clinical picture no longer met the criteria for nr-axSpA, 2 (3%) patients dropped out of the study. When analyzing the values of visfatin, PPM1A, MIF and serum calprotectin, no differences were found between nr-axSpA and r-axSpA, while the average concentrations of IgCD74 antibodies were slightly higher in patients with nr-axSpA (7.4 and 5.0 ng/ml respectively). It was shown that the probability of radiological progression from nr-axSpA to r-axSpA increased 3.308-fold with a one-unit increase in the ASDAS (Ankylosing Spondylitis Disease Activity Score) index.

Conclusion. The median duration of nr-axSpA diagnostics in the Kaliningrad region was 1 year. In terms of dynamics, after 3 years of observation, 44.1% of patients still met the criteria for nr-axSpA, and radiological progression to r-axSpA was observed in 23.5% of cases. High values of the ASDAS index and its increase by 1 unit increased the speed of radiological progression of nr-axSpA by 3.308 times. The difficulties in the early diagnosis of axSpA in practice necessitate the establishment of reference centers to obtain expert opinions on issues of differential diagnosis and treatment choices in patients with nr-axSpA and ankylosing spondylitis.
Cytomegalovirus infection and immune-mediated inflammatory rheumatic diseases: what is known today
Authors: Belov B. S. , Muravyova N. V.
Published: December 2024

Cytomegalovirus (CMV) infection is a common viral anthroponotic infection characterized by a variety of clinical and laboratory symptoms. There is a growing body of data on the association between CMV and the development of immune-mediated inflammatory rheumatic diseases (IIRD). The presence of immunopathological disorders caused both by the disease itself and using drugs with immunosuppressive effect determines the relatively high prevalence of comorbid active CMV in patients with IIRD. The commonality of the clinical picture of CMV infection and individual IIRDs often leads to problems in the diagnosis and differentiation between these diseases. The lack of recommendations for the rational use of antiviral drugs for therapeutic and prophylactic purposes in IIRD calls for further research.

Published: December 2024

Vasculitis associated with antineutrophil cytoplasmic antibodies (AAV) is a potentially dangerous autoimmune disease characterized by necrotizing inflammation of small blood vessels. In the pathogenesis of AAV, both innate and adaptive immunity are closely linked to neutrophil function. The study of the pathogenetic mechanisms of neutrophil activation in AAV may serve as a prerequisite for the development of more accurate and modern methods of laboratory diagnostics as well as new treatment approaches targeting neutrophils. The review presents an analysis of studies addressing the issue of neutrophil activation in AAV.

Interaksi yang intens di dunia maya telah mengubah cara masyarakat terlibat dalam kehidupan politik, terutama dalam konteks pemilihan umum. Berdasarkan laporan We are Social, jumlah pengguna aktif media sosial di Indonesia mencapai 167 juta orang pada Januari 2023, menunjukkan bahwa partisipasi masyarakat dalam politik kini dipengaruhi oleh kampanye modern yang memanfaatkan digitalisasi dan media sosial untuk mempromosikan calon dari berbagai partai politik. Penelitian ini bertujuan untuk menyelidiki dampak media sosial terhadap partisipasi politik, dengan fokus pada studi kasus Pemilihan Umum 2024 yang akan dilaksanakan pada 12 Februari 2024. Fenomena media sosial saat ini memungkinkan masyarakat terlibat dalam percakapan politik yang lebih terbuka dan terakses dibandingkan metode konvensional sebelumnya. Metode penelitian ini menggabungkan pendekatan studi kasus dan analisis literatur untuk mengevaluasi pengaruh media sosial terhadap partisipasi politik dalam konteks Pemilu 2024. Kampanye pemilu 2024 sangat aktif di berbagai platform media sosial, memicu perkembangan teknologi dan era digitalisasi yang pesat. Namun, ada tantangan seperti informasi hoax yang dapat merusak citra calon lawan politik dan harus diwaspadai dalam penggunaan media digital untuk kampanye.
Metabolite profiling of PGPR Bacillus subtilis BGKMR1: A potential strategy for managing Fusarium equiseti causing wilt in bitter gourd (Momordica charantia L.)
Authors: Ragul S , Vanitha S , Harish S , Johnson I , Irene VP , Senthil A
Published: December 2024

Wilt caused by Fusarium equiseti is one of the most destructive diseases that leads to substantial yield loss in bitter gourd. The F. equiseti strain CBEFE1((PQ111513.1) which was identified morphologically with falcate shaped three septate macroconidia and oval shaped microconidia and molecularly confirmed through amplification of the ITS region at 560bp was used for this study. Plant growth promoting rhizobacteria (PGPR) act as a sustainable biocontrol agent against major plant pathogens through multiple mode of actions. PGPR were isolated from native rhizopshere region in bitter gourd. The isolated PGPR Bacillus subtilis BGKMR 1 shows maximum mycelial inhibition of 68.73 % against F. equiseti in dual plate assay. The presence of metabolites produced by B. subtilis and F. equiseti along with its interaction were identified through the GCMS profiling. Primarily, pathogenic compound squalene (8.88 %) was identified in F. equiseti and antifungal compound 1,4-benzenedicarboxylic acid (6.1 %) was identified in B. subtilis. Further, B. subtilis BGKMR 1 during its interaction shows propanoic acid (14.69 %) which was found to have effectiveness against F. equiseti. KEGG analysis revealed pyrimidine metabolism in F. equiseti and nitrogen, alanine, aspartate and glutamate metabolism in B. subtilis and propanoate metabolism pathways were detected during its interaction. B. subtilis BGKMR 1 promote the seed germination rate upto 96 % and vigor index to 1919.04 when compared to control. The seed treatment with soil application of B. subtilis BGKMR1 reduced disease incidence upto 25.95 % under glass house condition. Moreover, B. subtilis BGKMR1 treated plants shows enhanced defense enzymes activity such as peroxidase, polyphenol oxidase and phenylalanine ammonia-lyase indicating induction of systemic resistance. Therefore, B. subtilis BGKMR 1 contains novel antifungal metabolites which were identified via GC-MS and induced defense enzyme activity highlights its practical application as a sustainable and eco-friendly solution for managing wilt disease in bitter gourd.
Strategic Directions for Sustainable Development of the Odesa Region Until 2030
Authors:   Odesа Polytechnic National University, Filippov Volodymyr , Neykov Sergey ,   Odesa Institute of Entrepreneurship and Law, Yangulov Elvin ,   Odesа Polytechnic National University
Published: December 2024

The article is devoted to the study of the strategic development of the
Odesa region until 2030 in the context of the current challenges related to the
war in Ukraine. The paper considers three possible scenarios for the socioeconomic development of the region: inertial, mobilization, and innovation. It
is determined that the most realistic scenario under current conditions is the
inertial scenario, which involves maintaining a stable socio-economic
situation. However, the region also has opportunities to implement elements
of the mobilization and innovation scenarios even during wartime, which will
contribute to a quick transition to full development once peace is established.
The proposed recommendations for the implementation of the development
strategy of the Odesa region are based on a systematic approach to
management, the use of decentralization mechanisms, ensuring investment
attractiveness, and adapting to changing market conditions. The article also
outlines prospects for further research in the field of strategic management of
small businesses to achieve sustainable development goals.

В статье сформулированы аргументы в пользу самостоятельной значимости проблемы понимания в современной философии науки. Очевидно, что невозможно создать серьезную концепцию понимания без исследования индикаторов понимания, используемых учеными. Изучив публикации в области искусственного интеллекта, естествознания и философии науки, автор описал критерии понимания, применяемые исследователями в этих областях знания. Основной результат состоит в предварительной классификации критериев понимания с учетом степеней универсальности этих критериев и степеней понимания изучаемых проблем, которые возникают у исследователей в процессе обдумывания и решения этих проблем при использовании формальных методов.

The article formulates arguments for the independent significance of the problem of understanding in contemporary philosophy of science. Obviously, it is impossible to devel-op a serious concept of understanding without examining the indicators of understanding used by scientists. Having studied publications in the field of artificial intelligence, natural science and philosophy of science, the author describes the criteria of understanding used by researchers in these fields of knowledge. The main result is a preliminary classification of the criteria of understanding in view of their degrees of universality and the degrees of understanding of the problems being studied, which researchers get in the course of thinking about and solving these problems when using formal methods.
ЭВОЛЮЦИЯ МАТЕМАТИЧЕСКОГО ДОКАЗАТЕЛЬСТВА С ТОЧКИ ЗРЕНИЯ ПСИХОЛОГИИ РАЗВИТИЯ
Authors: СТОРОЖУК А.Ю.
Published: December 2024

Целью статьи является рассмотрение этапов развития математического доказательства как последовательных этапов развития человеческого мышления, идущего по пути нарастания абстрактности. Разбирается точка зрения Я. Хакинга, выделяющего разные стили математического доказательства: подходы Декарта и Лейбница. Показано, что их нельзя рассматривать вслед за Хакингом как независимые подходы к пониманию доказательства. Они иллюстрируют развитие человеческого сознания, которое продвигается от конкретных представлений к абстрактному мышлению, поэтому подходы Декарта и Лейбница следует рассматривать как исторически развивающиеся подходы к пониманию доказательности.

The article is aimed to examine the stages of development of mathematical proof as successive stages in the development of human thinking which progresses towards the increase of abstrаction. The point of view of I. Hacking is analyzed, who identifies different styles of mathematical proof - the approaches of Descartes and Leibniz. It is shown that these styles cannot be considered, following Hacking, as independent approaches to understanding proof. They represent the development of human consciousness, which advances from concrete concepts to abstrаct thinking, therefore the approaches of Descartes and Leibniz should be considered as historically developing approaches to under-standing evidence.
НОЯБРЬ ИСКУССТВЕННОГО ИНТЕЛЛЕКТА
Authors: ЗАЙКОВА А.С.
Published: December 2024

Термин «зима искусственного интеллекта» был предложен по аналогии с термином «ядерная зима» для описания цепной реакции, вызванной пессимистическими прогнозами экспертов и приводящей к резкому сокращению исследований в сфере ИИ. Впоследствии термин «зима ИИ» под влиянием понятия «цикл ажиотажа» стал характеризовать инвестиционный цикл ИИ-исследований и только упрочился с появлением термина «весна ИИ» как синонима «бума ИИ». Последние несколько лет отдельные исследователи предрекают зиму ИИ, предупреждая о возможных проблемах, следующих за «пиком завышенных ожиданий». Однако более тщательный анализ показывает, что при предсказании зимы ИИ не учтено несколько факторов, ключевыми из которых являются институциональные и экономические, а также упущен из виду принципиально иной подход современного общества к ИИ-исследованиям. Это значит, что даже с наступлением «ноября ИИ» в обозримом будущем зима фундаментальных ИИ-исследований так и не наступит.

The term “artificial intelligence winter” was coined by analogy with the term “nuclear winter” to describe the chain reaction caused by experts’ pessimistic forecasts and resulting in a drastic decline in AI research. Later on, the term “AI winter,” influenced by the concept of “hype cycle,” began to describe the investment cycle of AI research and only became stronger with coining the term “AI spring” as a synonym for “AI boom.” Over the past few years, several researchers have been predicting an AI winter and warning of potential problems following the “peak of inflated expectations.” However, a more thorough analysis shows that predicting an AI winter does not take into account some factors, the key ones being institutional and economic, as well as ignores the fundamentally different approach of modern society to AI research. This means that even with the advent of “AI November,” the winter of basic AI research will not come in the near future.
The Poetics of the “Book of Travel” (“Safar-Nameh”) in Iranian Literature of the 19th — Early 20th Century
Authors: Konyashkina Tamara , Ardashnikova Anna
Published: December 2024

In this study the authors for the first time examine the evolution in the 19th – early 20th century of the safar-nameh genre – Iranian travel accounts. Widely in demand since the Middle Ages and having witnessed its heyday at the end of the century, by the middle of the 20th century this genre had been completely displaced from book circulation. The source base of the article is formed with the texts that have not been used yet as an object of philological analysis in either foreign or Russian Iranian studies. Meanwhile, being the most significant and voluminous works of this genre, they create wider opportunities for authors’ conclusions and generalizations. The analysis of these travel accounts made it possible to trace the process of gradual genre transformation and demonstrate specific mechanisms of change in the constitutive features of safar-nameh, quite clearly defined in the literary canon. Continuing to play the role of a “school” within which the mastery of storytelling and the basic structural principles of text organization were honed, the canon paved the way for the formation of narrative principles that are different from the classical model and are characteristic of modern plot-based narration. The fluidity of the genre specificity of safar-nameh serves as an example of the changes that traditional Iranian literature undergoes in this period.
