Abstract The use of botanical insecticides has increased in recent years due to the demand for effective products, particularly against insects resistant to conventional insecticides. Among these is Aedes aegypti, a well-adapted mosquito to urban environments that opportunistically feeds on humans and animals, contributing to the spread of virus. We evaluated the potential of essential oils (EOs) extracted from Eucalyptus citriodora, Eucalyptus staigeriana, Eucalyptus caryophyllus, and Mentha arvensis in terms of their larvicidal activity against Ae. aegypti. EOs’ compounds were determined using gas chromatography-mass spectrometry (GC-MS). Bioassays were performed on third instar larvae of Ae. aegypti to evaluate the larvicidal effects of EO dilutions in dimethyl sulfoxide (DMSO) at different concentrations. Mortality rates were observed over a 72-hour period to determine the efficacy of the treatments. Citronellal (86.64) predominated in E. citriodora, limonene in E. staigeriana (41.68), eugenol in E. caryophyllus (87.76), and menthol in M. arvensis (51.53%). EOs exhibited larvicidal activity from 10 ppm, with notable efficacy at 85 ppm, in which those from E. staigeriana and M. arvensis caused maximum mortality to Ae. aegypti larvae. Results revealed distinct efficacy patterns among EOs, with E. staigeriana displaying high toxicity within 24 h, achieving LC50 and LC95 values of 47.04 ppm and 97.35 ppm, respectively. Larvicidal effects within 1 h were observed for E. citriodora and E. caryophyllus. This study underscores larvicidal efficacy against Ae. aegypti, notably E. staigeriana, which had the lowest LC50 value. The findings indicate that the tested samples have potential for use as bioinsecticides.

Abstract We present here a floristic survey of the angiosperms found in the Reserva Ecológica Olho d’Água das Onças (REODO) in the semiarid region of Paraíba State, Brazil, to provide a basis for proactive conservation projects there. Fifteen excursions were carried out between August/2022 and April/2024 employing traditional methods of collecting and herborization of botanical material. The collections obtained were incorporated into the Manuel de Arruda Câmara Herbarium (HACAM) at the State University of Paraíba (UEPB), Campus I. We examined the floristic relationships between the study area and 15 other floristic surveys throughout the semiarid region of Paraíba State using a similarity analysis based on the Jaccard index. Two hundred and fifty species distributed among 168 genera and 50 families of angiosperms were identified with the following growth forms: herbaceous (74 spp.), subshrub (60 spp.), shrub (48 spp.), climber (45 spp.), arboreal (17 spp.), epiphytic (3 spp.), and parasitic (3 spp.). The most representative families were Fabaceae (38 spp.), Euphorbiaceae (24 spp.), Convolvulaceae (19 spp.), Malvaceae (18 spp.), Asteraceae (11 spp.), and Poaceae (11 spp.). The most representative genera were Ipomoea L. (8 spp.), Croton L. (7 spp.), Sida L. (7 spp.), Chamaecrista (L.) Moench (6 spp.), and Mimosa L. (5 spp.). Heteropterys arcuata C. Pessoa & Amorim (Malpighiaceae) and Solanum fernandesii V.S. Samp. & R. Moura (Solanaceae) were recorded for the first time in Paraíba State; Urvillea stipitata Radlk (Sapindaceae) represents a new record for the Caatinga. Similarity analysis revealed that the flora of REODO is more closely related to that of protected areas throughout the semiarid region of Paraíba State, underscoring its conservation priority. The study area was therefore found to contain significant floristic richness, especially within the context of the Caatinga, with 30 species endemics to this domain.

ABSTRACT Soil water balance models can be a good option for studying crop growth and yield responses under different water supply levels. The aim of this study was to evaluate the effect of different irrigation strategies on sunflower yield and water productivity using field experiments and soil water balance simulations. Two field experiments were performed. In 2018/19, four irrigation strategies (aimed at maintaining soil available water at 80, 70, 60, and 50% of total available water) were evaluated. In 2020/21 an irrigated and a rain-fed treatment were evaluated. The SIMDualKc model was calibrated and validated to simulate soil water balance and derive the dual coefficients using plant variables from field observations. Grain yield was highest in the treatment maintained at 70% of total available water in Study I, suggesting that a water replenishment reduction strategy may be an alternative to irrigation management, especially in locations where water is scarce. The statistical indicators showed good performance of the model in simulating the water available in the soil, with the coefficient of determination > 0.90 and modeling efficiency above 0.86 for all cases. The study allowed the calibration of the single and basal crop coefficients of sunflower, which are important parameters for irrigation management.

ABSTRACT The sorghum crop is considered one of the most important worldwide due to its versatility. However, water stress can be considered a significant threat to its yield. The search for products that mitigate water stress is a crucial area of research in agriculture and water resources management. Thus, the objective in this study was to evaluate the feasibility of using salicylic acid as a water stress attenuator in sorghum. The experiment was conducted in a screened environment in a randomized block design with a 4 × 2 factorial scheme, with four replicates. Four levels of water (40, 60, 80, and 100% of evapotranspiration) and two concentrations of salicylic acid (0 and 2.76 g L-1) were evaluated. Plant height, stem diameter, number of leaves, gas exchange, photosynthetic pigments, and chlorophyll a fluorescence were analyzed. Application of deficit irrigation depths reduced plant height, stem diameter, number of leaves, and total chlorophyll in sorghum. However, when these depths were associated with salicylic acid, it was observed that the damage was attenuated, especially in chlorophyll a and b. Furthermore, salicylic acid reduced leaf temperature and increased water use efficiency when applied alone. Thus, salicylic acid can be used to mitigate the effects of salt stress on sorghum plants.

Published: October 2024

ABSTRACT Objective: To identify and analyze users’ perceptions of access and use of health services and actions to monitor Systemic Arterial Hypertension (SAH) in Primary Health Care (PHC). Methods: This is a qualitative, descriptive and exploratory study based on 38 semi-structured interviews conducted with users selected from Basic Health Units (BHUs) in a large municipality in the state of Rio de Janeiro. Thematic content analysis was used to identify the empirical categories. Results: Users faced difficulties in scheduling appointments, accessing laboratory test results and medicines at the BHU. Home visits by Community Health Workers (CHWs) intermediated demands for appointments and tests. There were no health education activities and follow-up by the nursing team was residual. The doctor was the main reference, although links were weakened by turnover. Conclusion: The study identified the need to expand access to basic medicines and test results at the BHU, the role of nurses in promotional, preventive and clinical actions, the scope of CHWs’ work in health education and interprofessional work.

Indigenous Psychology or the construction of a mediation locus
Authors: Gomes-Souza Ronaldo , Sampaio Cláudia Regina Brandão , Tramontano Marcelo Claudio
Published: October 2024

Abstract This essay aims to explore the practical, theoretical, and methodological specificities of Indigenous Psychology, proposing the use of audiovisual languages as a means to research, document, and deepen the dialogue between academic and Indigenous communities. This field is under development and reflection, adopting a transdisciplinary, complex, systemic, and dialogical perspective that contributes to the decolonization of psychology itself by creating spaces, or mediation locus, for the recognition of the existence and resilience of Indigenous cosmology and good living. We discuss audiovisual media as a mediating instance between distinct ways of understanding the historical world through image and sound capture and editing processes. We conclude that this strategy de-hierarchizes the relationship between academia and communities, striving to empower, amplify, and enhance the voices and visibility of all involved, bringing practical, theoretical, technical, methodological, and ethical advancements in constructing, disseminating, and sharing knowledge.

Efficacy of a Surgical versus a Nonsurgical Approach in the Treatment of Peri-Implant Diseases: A Systematic Review and Meta-Analysis
Authors: Eltawil Youssef , Molinos Jaime , Molina Barbara , Jiminez Jaime , Romero Pablo
Published: October 2024

The objective of the study was to compare the surgical vs. the nonsurgical techniques in the treatment of peri-implant diseases and to obtain a comprehensive analysis of the effects on BOP/probing depths when applying either the surgical technique vs. a nonsurgical technique. Twenty-seven articles with a total of 29 trials were selected from PubMed, Medline, Embase and Cochrane library. The articles were published in the past 10 years and complied with the inclusion criteria. Three metanalyses were performed evaluating the effects of surgical and nonsurgical treatments on the reduction in probing depths as well as on bleeding on probing. Fifteen studies involved the treatment of peri-implant diseases with the surgical approach and 14 studies involved the application of the nonsurgical protocol (6 treating peri-implantitis and 8 treating mucositis). A mean reduction in probing depths of 2.31 mm were obtained when the surgical approach was applied for peri-implantitis and a mean of 57% reduction in bleeding on probing was obtained with the surgical protocols. Inflammation was significantly reduced when nonsurgical protocols were applied for mucositis. The highest reduction in probing depths and bleeding on probing was found when emdogain was used with allograft and resorbable membranes. Nonsurgical treatments with extensive hygiene measures were mainly indicated in the treatment of mucositis and do not present bone gain but lowers or maintains probing depths and reduced bleeding on probing. Further studies should be performed with a standardized definition of peri-implantitis with the same surgical or nonsurgical protocol applied as well as the same follow-up period in order to correctly identify the ideal treatment of choice.
The emergence of labial harmony in Old Hungarian
Authors: Cser András , Oszkó Beatrix , Várnai Zsuzsa
Published: October 2024

Hungarian displays both backness harmony (inherited from Proto-Uralic) and labial harmony, the latter developing in Old Hungarian. This paper sets out to explain the fact that the emergence of labial harmony, i.e., the progressive spreading of the feature [labial] in Late Old Hungarian results from an apparent change in the earlier regressive direction of spreading for the same feature. The question addressed here is what caused the change in the direction of the spreading. The hypothesis advanced is that Early Old Hungarian regressive spreading of labiality did not affect lexical cues, since [labial] was a redundant feature; the spreading was motivated by coarticulatory mechanisms. However, as [labial] became a robust contrastive feature in the Old Hungarian period, it aligned with backness in its spreading direction to enhance lexical recognisability. The argument also implies that while labial harmony owes its origin to a pattern rooted in coarticulatory mechanisms, in its mature form it acquired a superimposed perceptual motivation.

Published: October 2024

A step-by-step protocol details the euthanasia, fixation and staining of whole Daphnia samples for micro-CT imaging. While commonly used PTA concentration of 0.3% works for staining small juveniles within 48 h, a higher concentration of PTA (3%) is needed to provide homogeneous staining of the whole adults in 3 days. Micro-CT reconstructions of samples imaged using synchrotron micro-CT reveal histological (microanatomic) features of organ systems, tissues, and cells in the context of the entire organism at sub-micron resolution, and in 3D. Protocol also recommends resin embedding of samples if immediate imaging is not available.

Multi‐Actor Housing to Address Vulnerabilities at a Personal and Local Level
Authors: Anastasiou Aikaterini , Aernouts Nele , D'Auria Viviana , Ryckewaert Michael
Published: October 2024

In response to an everlasting housing crisis, cities worldwide have witnessed a surge in alternative housing initiatives (AHIs) driven by third‐sector organisations. In Brussels, a network of third‐sector organisations has been developing strategies with each other and local authorities, resulting in a plethora of initiatives focusing on various critical situations. Drawing on ethnographic research in a Brussels AHI, this article investigates how its complex multi‐actor structure affects the daily life of its inhabitants both within their dwellings and the wider neighbourhood. By capturing the tactics employed by third‐sector actors on the ground, which often deviate from their initial strategy for reclaiming the right to housing, as well as the homing practices of the inhabitants, the article focuses on tracing how and why such a housing configuration does or does not address its inhabitants’ interplaying vulnerabilities related with the housing crisis as well as their relationship with the local urban fabric.
A “Promise” of Proximity in Pandemic Times: Governing Urban Marginality in the Netherlands and France
Authors: Van de Wetering Simone
Published: October 2024

In early 2020, the world went into lockdown. New norms of social distancing and remote work were implemented in response to the Covid‐19 crisis. These appeared to challenge a key aspect of the current governance of urban marginality: proximity. This article asks how proximity, involving physical presence in the neighborhood and direct contact with urban residents, changed and remained the same during the pandemic and what that means for the governance of urban marginality beyond pandemic times. To answer this question, I draw on ethnographic research in marginalized neighborhoods in the Netherlands and France. Studying how local actors practiced proximity and responded to the pandemic, I found that Covid‐19 did not simply challenge proximate governance. While physical presence decreased, the pandemic instigated direct daily contact and community response and relief, albeit at a distance. Yet, the pandemic also exposed and aggravated existing difficulties in working “close by,” particularly integrated approaches and civic engagement. The analysis, first, highlights the importance of daily contact beyond mere physical presence in the neighborhood, deepening current understanding of proximity in practice. Second, it demonstrates that local actors continuously negotiate community involvement, advancing understanding of civic engagement in proximate governance and the assumed inherent qualities and fixed nature of “the local.” Third, it challenges the centrality of “the local” in urban governance, revealing the impact of a “far‐away” state on local actors’ ability to improve living conditions in marginalized neighborhoods, in and beyond pandemic times.
Spatial Politics of Cultural Production: Negotiating Workspaces and Resisting Displacement at Industrial Heritage Sites in Berlin
Authors: Merkel Janet
Published: October 2024

Derelict industrial spaces have been crucial spatial resources for artists and cultural production for decades, often forming vibrant cultural clusters. However, these spaces are increasingly threatened by speculative real-estate development and displacement through more “productive” creative industries. The case of Alte Münze in Berlin provides empirical insight into the politics, practices, and strategies essential for preserving these heritage sites in the long term for cultural use. This research underscores the need for supportive planning regulations that combine cultural policy with urban planning, advocate for public-civic partnerships, and promote public or community-based ownership models. The findings extend to small-scale manufacturers and businesses facing similar challenges in maintaining workspaces amid competitive urban land use pressures.
Current Issues of Cryopreservation and Storage of Human Reproductive Biomaterial
Authors: Belova D. A.
Published: October 2024

With the development of assisted reproductive technologies (ART), contracts covering cryopreservation and the storage of germ cells, as well reproductive organ tissues and embryos are beginning to find wide practical application. Parties to such contracts are faced with questions not currently set out in the current legislation of the Russian Federation. This aim of this article is to identify legal models capable of resolving the most pressing issues arising from these contracts. It is proposed that the following types of biomaterial be reviewed as a continuation of the human body: reproductive biomaterial extracted from the human body in the aims of subsequent reintroduction, and capable of fulfilling that biological function for which it is designated; as well as material aimed at restoration or improvement of organ function. Any intervention upon such biomaterial should be qualified as intervention upon human health. Thus any medical organization found to be in violation of its obligation to preserve health must compensate for any damage caused to a patient’s reproductive health - as set out in the rules of chapter 59 of the Civil Code of the Russian Federation. The author suggests the notion of “abandoned biomaterial” be incorporated in Russian legislation. “Abandoned biomaterial” presupposes the termination of the rights of a person to this biomaterial and enables the medical organization, while ensuring its preservation, to utilize such biomaterial or to use it for research purposes. This would ensure the protection of human rights and legitimate the interests of the contracting party in the event of any violation of the terms of the contract by the client. The author also proposes legal models for the resolution of conflicts related to the plurality of contractual parties, as well as to postmortem human reproduction.
Theoretical Approaches to the Regulation of Bioeconomy
Authors: Kubyshkin A. V.
Published: October 2024

The development of science and technology, as well as the introduction of innovations into the production sphere, have led to the emergence of such a phenomenon as the bioeconomy. At the present time, there is no versatile definition of the concept of bioeconomy either at the national level or at the level of interstate integration associations and international organizations. To analyze the key features of the concept of bioeconomy and to identify the main approaches to the essence of this phenomenon. This is important for the understanding of directions of development of the regulatory environment in relation to bioeconomy in the Russian Federation. The article analyzes the definitions of the concept of bioeconomy at the level of the International Advisory Council on Bioeconomy (IACB), the Organization for Economic Cooperation and Development (OECD), the European Union (EU), and individual states. The author examines a range of approaches to regulating bioeconomy. The research is based on formal-logical, dogmatic methods, the comparison method and the axiological approach. The paper presents approaches to the concept of bioeconomy as a phenomenon. The author analyzes how bioeconomy relates to the circular economy (closed-loop economy) and the linear (traditional) economy. The article presents a range of approaches to the regulation of bioeconomy through the lens of proactive law and proposes a mechanism for its regulation with the help of a symbiotic regulator. The main elements of such a reg ulator are referred to in the article. They include normative regulation, the presence of ef fectively functioning organizational structures, and properly functioning processes of interaction between organizational structures and entities. The author examines a regulation method entitled ‘ethical licensing’, highlights its advantages and disadvantages, and gives recommendation on the subsequent use of this method. Due to its complex nature, bioeconomy as a phenomenon requires specific approaches to its regulation.

The detection and analysis of offshore seismic processes worldwide often require the use of ocean-bottom seismometers (OBSs). However, most OBS deployments are done with stand-alone stations, with data recovery delayed by months. On the other hand, electrically cabled OBS, which allows for real-time monitoring, remains exceptional due to the high cost of manufacturing, installation, and maintenance. Here, we present a new perspective for cabled array of OBSs, using purely optical seismometers, plugged at the end of long fiber-optic cables, aimed at reducing their cost for observatories requesting real-time data. The optical seismometer was developed in the last decade by the École Supérieure d’Électronique de l’Ouest, based on the Fabry–Perot interferometer, tracking at high resolution the displacement of the mobile mass of a mechanical geophone (no electronics nor feedback). A prototype was successfully installed at the top of La Soufrière volcano of Guadeloupe in 2019. We replicated this sensor and installed it 5 km offshore Les Saintes islands, at 43 m depth (Guadeloupe, Lesser Antilles) to characterize the swarm-type activity persistent after the 2004 M 6.3 earthquake (Interreg Caraïbe PREST project). The installation cruise, FIBROSAINTES, was supported by the Flotte Océanographique Française. A plow designed by GEOAZUR carried the cable and was pulled on the seafloor by the vessel ANTEA. The landing cable was connected to the interrogator, with a real-time telemetry to the Institut du Physique du Globe de Paris/Observatoire Volcanologique et Sismologique de Guadeloupe. The OBS has been qualified with local land-based velocity broad band stations. The analysis of local earthquake swarms suggests transient creep on the major normal faults. This successful installation opens promising perspectives for real-time monitoring in on-land or offshore sites, presenting harsh environmental conditions, in which commercial, electrical seismic sensors are difficult and/or costly to install and maintain.
Preliminary Results of a Workplace Health Promotion Program in Higher Education
Authors: Murphy April , Macy Gretchen , Basta Tania
Published: October 2024

Background: Employees of higher education have an increased risk for stress, burnout, and turnover. Workplace Health Promotion (WHP) programs have been shown to improve quality of life, reduce individual health risks, improve morale, reduce health care costs, and increase employee retention. 
Aim: The aim of this study was to determine the impact of a WHP initiative on employee intent to stay, life/work balance, and work-related quality of life. 
Methods: This study employed a cross-sectional design at a Midwestern university. All faculty and staff were invited to participate in an Employee Wellness Hour, which allowed them to take an additional hour per day to participate in wellness-related activities. Those who chose to participate were required to track their wellness activity on a weekly basis in Qualtrics and invited to participate in a survey examining their intent to stay, life/work balance, and work-related quality of life. Analyses were conducted to determine whether participation in the Employee Wellness Hour had an impact on employee intent to stay, their life/work balance, and work-related quality of life. 
Results: Results indicated that those who participated in the Employee Wellness Hour were more likely to stay with their current employer and rated their working conditions more positively. 
Conclusions: The cost of employee turnover is immense, making it imperative that employers develop and implement innovative solutions to retain employees and improve working conditions. This study provided preliminary evidence that WHP programs can have a positive impact on retention and working conditions among those employed in institutions of higher education.

The Expectations of Others
Authors: García-Lembergman Ezequiel , Hajdini Ina , Leer John , Pedemonte Mathieu , Schoenle Raphael
Published: October 2024

Using a novel dataset that integrates inflation expectations with information on social network connections, we show that inflation expectations within one's social network have a positive, causal relationship with individual inflation expectations. This relationship is stronger for groups that share common demographic characteristics such as gender, income, or political affiliation and when salient information disseminates through the network. In a monetary union New-Keynesian model, socially determined inflation expectations induce imperfect risk-sharing and can affect the inflation and real output propagation of local and aggregate shocks. To reduce welfare losses due to socially determined expectations, monetary policy should optimally put more weight on the inflation rate of socially more connected regions.
The problem of knowing future phenomena
Authors: Kuskova Svetlana M.
Published: October 2024

The paper is devoted to the problem of epistemic conditions of cognition of future phenomena.The problem is that the cognizable aspects of information are based on the evolutionary mechanisms of adaptation of the body, which are reduced in humans, and on the rational principles of human cognition, which are mixed with irrational prophecies. The solution is to separate the heuristic possibilities of theory from empirical guesses and consider the structures of theoretical knowledge that process information about possible and impossible facts.The aim of the paper is to discover a mental act directed at the future, which cannot be reduced to extrapolating the past and varying alternatives. The conditions of the possibility of knowing about the reality of the future as a mode of time, and the idea of a specific event in the future are split.The following hypothesis is considered: cognition of the future is based on thinking about the possible and necessary relations of an object to an integral system including a subject.The attitude of the mind towards the future is not a cognitive act like receiving information, the source of which is problematic. This is not animal foresight, not divination, not planning. Cognition is understood not as a perception of the objective properties of a phenomenon, but as its construction according to the rules of the organization of consciousness. In general, the future is not knowable, but there are types of phenomena other than the causal concept of cognition that justify information about the future. Theoretical knowledge of the predispositions of a situation involving an object is proactive. The subject of prediction is not only the truth about the future, but also a judgment about what exactly will not happen. This limitation narrows the scope of possible alternatives. The elementary acts of realizing that an event is not yet happening have been investigated by the phenomenology of Buddhism. They are directed at the stages of the same process. The conclusion from content of one temporal interval to content of another interval is based on theoretical constructions that do not have spatiotemporal characteristics. Information about the future is limited by theoretical knowledge of the holistic situation and the properties of the object that arise as a result of its inclusion in this situation.
Modeling creativity in artificial intelligence: possibilities and limits
Authors: Krylov Nikita A.
Published: October 2024

The article is dedicated to exploring the possibilities and limitations of developing creative artificial intelligence, particularly the ability of machines to determine the level of creativity in the objects they produce. To assess creativity, a three-step model of novelty is proposed, including ontological, subjective, and semantic levels. Three features of creative ideas or artifacts are identified: novelty, unexpectedness, and value. The article describes the model of a competitive generative network called "CAN: Creative Adversarial Networks," which creates new artistic styles and evaluates their novelty. The possibilities and limitations of modeling humor in creative artificial intelligence are discussed. The article analyzes examples of successful work by neural networks that generate jokes and write scripts, showing that the limitation of such systems is the machine's lack of a sense of context, space, and time. Additionally, a crucial condition for successfully writing jokes is the ability to laugh at them; humans can consciously choose the topic and format of humor, while machines lack their own goal-setting. It is shown that the technologies developed to date can be generalized as "weak creative artificial intelligence" since they can create new objects but are not capable of goal-setting and reflection. However, the possibilities of artificial intelligence are constantly expanding, changing our understanding of the limits of modeling natural intelligence.
The peculiarity of Pushkin-related texts in modern Russian literature
Authors: Nekrasova Irina V. , Ustimenko А. А.
Published: October 2024

The topic of the article is relevant and timely, because the work is devoted to the study of works of mainly modern Russian literature. This article uses an integrated approach to the analysis of literary texts, including interpretative, analytical, intertextual and other methods. In the course of the conducted research, some "secondary" works of past periods of the literary process were updated, which in one way or another addressed the legacy of A.S. Pushkin. Empirical material: in the main part of the article, attention is focused on three categories of texts from the late XX–XXIst centuries, which use Pushkin's reminiscences, the Pushkin code, and the Pushkin myth. They are divided into three groups in the article: variations of modern literary references to the novel "Eugene Onegin"; works from the category of "alternative history", suggesting the construction of a different - fictional - fate of Pushkin; the use by modern authors of a kind of "literary franchise" of the legacy of Pushkin. As a result of the analysis, we come to the following conclusions: the importance of Pushkin's legacy for modern culture and literature is enormous. It encourages current artists of the word to bold, but not always productive experiments related to variations of Pushkin's texts, their sequels, parodies,new alternative historical twists and more. We believe that such phenomena as a whole can be considered an important component of the modern literary process, which should help restore interest in the classical heritage among younger generations.

In conditions of water shortage, sustainable agricultural development requires the use of water-saving technologies, including the use of water-retaining substrates based on activated carbon. In this work, the textural and adsorption characteristics of activated carbon obtained from plant waste were studied at different mass ratios of the sorbent and KOH (1:1, 1:2, 1:3 and 1:4). The aim of the study was to determine the optimal activation conditions for creating a material with a high specific surface area and a developed porous structure. The results showed that the largest pore volume (1.6 cm3/g) and a high degree of microporosity are achieved at a ratio of 1:3, which is confirmed by the analysis of pore distribution using the DFT and BJH methods. FTIR spectroscopy revealed the presence of functional groups (O–H, C=O and C–O) that contribute to water conservation. The differential pore volume distribution (dv(r), cm3/Å/g) also demonstrated that at a ratio of sorbent and KOH (1:3), the sample structure optimally combines micropores and mesopores, which increases the adsorption capacity of carbon.

В данной работе исследованы морфологические и структурные особенности наночастиц магнетита, синтезированных методом жидкофазного горения с использованием различных топлив – мочевины и глицина. Полученные результаты показали значительные различия в морфологии и кристалличности наночастиц в зависимости от типа топлива. Мочевина способствует формированию однородных и мелкодисперсных наночастиц с высокой степенью кристалличности, тогда как глицин приводит к образованию агломерированных частиц с примесями оксида углерода. Результаты рентгенофазового анализа подтвердили успешное получение магнетита с различной степенью кристалличности и неодинаковым фазовым составом, зависящим от использованного топлива. Выбор топлива показал значительное влияние на качество и свойства наночастиц магнетита, что подчеркивает необходимость оптимизации условий синтеза для различных приложений.

The complexation behavior in systems containing Ni2+, MoO42−, P2O74−, Cit3− - ions have been thoroughly investigated. The study determined the composition and instability constants of both mono- and biligand complex compounds at a constant ionic strength of the solution (Ic=1). By analyzing the concentration ratios of the complexing agent and ligands, the composition of mono- and polyligand complexes was elucidated. The complexation study utilized the potentiometric method, which is based on the functional dependence of the potential of the indicator electrode on the concentration of the complexing agent ions. The results enabled the calculation of the ionic composition of aqueous solutions of nickel complexes with citrate and diphosphate ions, depending on their concentrations. A proposed scheme for the formation of heteronuclear nickel-molybdenum complexes takes into account the sequence of component introduction into the electrolyte to form complexes of a specific composition. These findings were applied to develop electrolyte compositions for coating with alloys based on iron subgroup metals with molybdenum. These alloys exhibit several valuable properties, including corrosion resistance, electrocatalytic activity in hydrogen production, and enhanced operational characteristics.

Butterflies are classified first according to their outer morphological qualities. It is required to analyze their genital characters when classification according to their outer morphological qualities is not possible. The genital characters of butterflies can be obtained using various chemical substances and methods; however, these processes can only be carried out with some certain expenses. Furthermore, the preparation of genital slides is time-consuming since it requires specific processes. In this study, a new method based on the extreme learning machine (ELM) and Gabor filters (GFs), which is an image processing technique, was used for the identification of butterfly species as an alternative to conventional diagnostic methods. GFs have been recognized as a very useful tool in texture analysis, due to their optimal localization properties in both the spatial and frequency domains, and have been found to have widespread use in computer vision applications. To obtain the appropriate features from butterfly images in the spatial domain, 20 filters were designed for the various angles and frequencies (5 frequencies and 4 orientations). The diagnosing of butterflies was performed through ELM, with texture features based on GFs. The classification process was performed with a 75%–25% training-test set for different activation functions and the recognition performance value was obtained as 97.00%. In addition, the recognition success rates with ELM were compared to other machine learning methods and it was seen that ELM has a more significant success rate in butterfly identification than other methods. As a result, the proposed method is a suitable machine vision system for detecting butterfly species
