Bocskai István példája a 19-20. század kritikus korszakaiban
Authors: László Andor
Published: April 2024

The goal of this study is to give an overview of the figure of István Bocskai, the prince of Transylvania in the public eye in three critical periods of the 19th and 20th centuries, particularly in political thought. He is mentioned often during difficult times, while before and after these periods he is referenced much less frequently. The experience of the Revolution of 1848–1849 constituted an emotional basis for the formation of the Hungarian national identity, and the previous struggles of the Hungarian Estates were seen as parallels. The contemporaries saw a connection between the glorious period of the 17th century and their own times. This connection elevated Bocskai’s revolution to being seen as one of the great chapters of Hungarian history, and the prince became a member of the national pantheon. During the crisis following World War I, and later around World War II, different considerations gained importance, and the prince’s image became much more multifaceted. However, Bocskai still wasn’t a divisive personality, he was seen as a great politician and freedom fighter. Every political faction and ideology considered him an example to be followed, and found something among his values, achievements or deeds that fit their current message. It can be seen that the meaning of the past changes constantly, and different sources of remembrance paint a confusingly varied picture of Bocskai, who is constantly “repositioned” in public memory, but the role of history in politics doesn’t change: it underlines and authenticates contemporary messages.

Published: April 2024

Andrographis paniculata (Brum. f.) Wall. ex Nees is an important medicinal plant of tropical Asia and has been used widely for a long time for different clinical ailments. Despite profuse flowering and a high percentage of fruit set,the number of seedlings in the natural population is the bare minimum. Knowledge regarding the seed ecology and seedling phenology of A. paniculata, is needed to formulate conservation strategies for the species. Therefore, a detailed study on seed ecology and seedling phenology has been conducted. During seed ecological studies,seed production, seed-set percentage, seed-ovule ratio, mechanism of seed dispersal, seed structure along with germination status, viability, dormancy and its breaking, and percentage of moisture content loss have been studied. Seeds exhibit some kind of dormancy [germination percentage (GP) = 28.51 ± 0.98, mean germination time (MGT) = 33.07± 0.89 days, and germination index (GI) = 0.73 ± 0.08] which can be effectively overcome through acid scarification using H2SO4 and hot water treatment. The species shows epigealphanerocotylar germination. The hypocotyls exhibit rapid growth, and cotyledons emerged at 7.52±0.27 TARA (Time After Radicle Appearance in days). Seedling is characterised by a thickened, hairy hypocotyl, a distinct collet, a pair of paracotyledons, and three pairs of eophylls in opposite decussate phyllotaxy. The studies on seed ecology and seedling phenology play a significant role in understanding how the shortening of the inception period enhances the germination status, and distinct seedling morphology provides the opportunity to formulate conservation strategies in their wild habitat.
Jeu des pôles personnels dans la publicité verte en français et en polonais
Authors: Hajok Alicja , Miladi Lidia
Published: April 2024

Green advertising encourages the public to adopt ecoresponsible behaviour in view of the deterioration of the environment. Thus, to involve everyone personally or collectively, it uses the imperative mode and deictics. The aim of this study is to highlight the main themes conveyed in green advertising in France and Poland, and also to show the interplay of personal poles in imperative slogans that become rallying phrases for the green cause. Polish makes general use of the imperative in the 2nd person singular, where- as French makes extensive use of the 2nd person plural. In both languages, the use of the 1st person plural is frequent, often accompanied by an adverb ensemble (razem) to emphasise the collective involvement in adopting eco-responsible actions.

”When We Ride Together, She’s More like a Friend than a Mum”: Mothering Variations in Three Horse Story Series by Pia Hagmar

This article analyzes how the horse story setting problematizes the conception of the good mother and normative mothering, by elucidating how the gazes of the young main characters on their mothers function in relation to the notion of the good mother, how this influences the mothering and how the mothering characters challenge this notion. Mothering is seen here as caring practices, which can be performed by people other than mothers. The analysis of three horse story series by Pia Hagmar, the books on Klara (1999–2008), the books on Millan (2012–2014) and the books on Juli (2019–2021), shows that the series depict motherhood and mothering at the intersection between the conception of the good mother and the good horse person. The common denominator is nurturing traits that make personal needs take the back seat – for the traditional good mother to the benefit of her children, for the good horse person to the benefit of the horse. Hagmar normalizes the presence of several mothering characters in addition to their mothers around the horse girls. Furthermore, these characters, who function as mothering variations, contribute to the creation of a solid caring environment, reducing the demands on mothers who try to be everything to their children. Although the daughters’ views of their mothers are sometimes critical, Hagmar allows the mothers to be imperfect, partly incompetent, or simply women with their own agency,interests and needs outside of motherhood. In addition, a mother-daughter relationship built on a common interest in horses allows for a friendship with a common focus – the horse.

Mitigating digestive disorders: Action mechanisms of Mediterranean herbal active compounds
Authors: Kmail Abdalsalam
Published: April 2024

This study explores the effects of the Mediterranean diet, herbal remedies, and their phytochemicals on various gastrointestinal conditions and reviews the global use of medicinal plants for common digestive problems. The review highlights key plants and their mechanisms of action and summarizes the latest findings on how plant-based products influence the digestive system and how they work. We searched various sources of literature and databases, including Google Scholar, PubMed, Science Direct, and MedlinePlus. Our focus was on gathering relevant papers published between 2013 and August 2023. Certain plants exhibit potential in preventing or treating digestive diseases and cancers. Notable examples include Curcuma longa, Zingiber officinale, Aloe vera, Calendula officinalis, Lavandula angustifolia, Thymus vulgaris, Rosmarinus officinalis, Ginkgo biloba, Cynodon dactylon, and Vaccinium myrtillus. The phytochemical analysis of the plants showed that compounds such as quercetin, anthocyanins, curcumin, phenolics, isoflavones glycosides, flavonoids, and saponins constitute the main active substances within these plants. These natural remedies have the potential to enhance the digestive system and alleviate pain and discomfort in patients. However, further research is imperative to comprehensively evaluate the benefits and safety of herbal medicines to use their active ingredients for the development of natural and effective drugs.
Industrial device for the continuous UV-C treatment of fruit and vegetables: simulation-aided design and model validation
Authors: Lysova Natalya , Solari Federico , Bocelli Michele , Volpi Andrea , Montanari Roberto
Published: April 2024

The irradiation of foods with UV-C light is a non-thermal and non-chemical treatment that allows for achieving several benefits, from surface decontamination to hormetic effects on biological matrices. Nowadays, even if its effects have been extensively proven and discussed, UV-C radiation is not widespread on an industrial level for the treatment of solid and liquid foods, mainly due to technical limitations and the non-uniformity of legislation for different products and among different countries. In this study, numerical simulation was adopted as a tool for the design and optimization of a device for the UV-C treatment of fruits and vegetables. After validating the modelling approach, the radiation treatment was evaluated for different product configurations. The proposed approach aims to facilitate the implementation and the scale-up of the UV-C treatment in the food industry, as it allows for assessing its effects under different operating conditions, prior to the physical prototyping stages.
Polyurethane foam reinforced with Ag nanoparticle decorated ZnO nanorods: a dual-functional approach for improved antibacterial and mechanical properties
Authors: Farrokhi Zeynab , Kanvisi Mojtaba , Ayati Ali
Published: April 2024

This study introduces a novel approach by incorporating pristine ZnO nanorods and Ag nanoparticles decorated ZnO nanorods into a polyurethane foam matrix. This synergistic combination aims to enhance the foam’s antibacterial properties while investigating its impact on mechanical strength. Nanoparticles and prepared nanopolymer were characterized by different methods like XRD, TEM, SEM, and EDS. The mechanical characteristics and antibacterial properties of prepared polyurethane composites were investigated in the presence of Escherichia coli and Bacillus subtilis. A much higher level than reported in the literature was found for PU films filled with ZnO nanorods. Incorporating nanoparticles into polyurethane nanocomposites has been demonstrated to significantly improve polyurethane’s antibacterial properties. The results revealed that ZnO/PU antibacterial efficiency decreased with increasing ZnO nanofiller content, while AgNPs@ZnO/PU composite antibacterial efficiency increased with increasing AgNPs@ZnO nanofiller content. Also, the weak coordinate bond between ZnO and Ag in the PU chain extender was demonstrated. Increasing the ZnO content to 1.4 wt% resulted in greater Young’s modulus and tensile strength, which increased when the ZnO content was increased further. Such a dual-functional enhancement holds promise for applications requiring both antimicrobial efficacy and mechanical integrity.
Imagery, self-efficacy and chronic pain
Authors: Ross-Stewart Lindsay , Miles Lindsay
Published: April 2024

Worldwide, chronic pain is one of the most common chronic conditions with 1.9 billion people affected, with some estimates as high as 30 % of the world’s population experiencing chronic pain. Many of the people living with chronic pain are from lower-income communities and may not have access to advanced medical care, leaving them to deal with their chronic pain alone and without proper treatment. When treated, opioids are the most common option, however current concerns with addiction have highlighted the need for complementary and alternative treatment approaches. Previous research has found that with increased self-efficacy, a person with chronic pain could feel more control of their ability to complete tasks whether or not pain is present. Increasing a person’s self-efficacy can also help them develop better coping strategies and adapt to their pain as they experience it. One way to increase self-efficacy is through using imagery. Through guided imagery sessions, people with chronic pain have reported less pain in their target areas and have increased self-efficacy, increased quality of life, and decreased pain. As imagery is affordable, accessible, and safe, people from any socioeconomic status should be able to take advantage of this treatment, making imagery an important part of the current public health discussion on treatment for chronic pain.

Published: April 2024

Carbon nanotubes (CNTs) have garnered significant attention due to their extraordinary mechanical and other physical characteristics. This study demonstrates that incorporating a small number of carbon nanotubes, ranging from 0.1 to 0.9 wt.%, into a polymer, can effectively enhance its mechanical properties. In comparison to the pure polymer, the addition of −0.3 % carbon nanotubes resulted in a notable 24.1 % increase in tensile strength, a 4.4 % increase in compressive strength, a significant 319.5 % increase in the fatigue life cycle at 0.1 % carbon nanotubes, and a remarkable 43.0 % increase in fracture toughness at 0.3 wt.% carbon nanotubes.
Three Marxist Lessons for 21st-Century History and Philosophy of Science
Authors: Esposito Maurizio
Published: April 2024

What can we learn from a Marxist history and philosophy of science? There are at least three crucial lessons that scholars should seriously reassess. First, the idea that there is a constitutive relation between practice and theory in knowledge production. This was a central concern for many Marxist HPS scholars and led them to conceive “science” as a praxis and as a situated, and not exclusively intellectual, enterprise. Second, the idea that there is a thread connecting social relations, technologies, and scientific abstractions. Modes of thinking and understanding are related to particular social formations. And third, the idea that modern science is both a cause and product of capitalist modes of production, which expanded globally and generated all sorts of inequalities and polarizations. Altogether, these lessons put forward a coherent perspective addressing the socioeconomic nature of scientific knowledge, which is still relevant today.
Reconfiguration of Behavioral Signals in the Anterior Cingulate Cortex Based on Emotional State
Authors: Lindsay Adrian J. , Gallello Isabella , Caracheo Barak F. , Seamans Jeremy K.
Published: April 2024

Behaviors and their execution depend on the context and emotional state in which they are performed. The contextual modulation of behavior likely relies on regions such as the anterior cingulate cortex (ACC) that multiplex information about emotional/autonomic states and behaviors. The objective of the present study was to understand how the representations of behaviors by ACC neurons become modified when performed in different emotional states. A pipeline of machine learning techniques was developed to categorize and classify complex, spontaneous behaviors in male rats from the video. This pipeline, termed Hierarchical Unsupervised Behavioural Discovery Tool (HUB-DT), discovered a range of statistically separable behaviors during a task in which motivationally significant outcomes were delivered in blocks of trials that created three unique emotional contexts. HUB-DT was capable of detecting behaviors specific to each emotional context and was able to identify and segregate the portions of a neural signal related to a behavior and to emotional context. Overall, ~10 as many neurons responded to behaviors in a contextually dependent versus a fixed manner, highlighting the extreme impact of emotional state on representations of behaviors that were precisely defined based on detailed analyses of limb kinematics. This type of modulation may be a key mechanism that allows the ACC to modify the behavioral output based on emotional states and contextual demands.

The history of influenza outbreaks extends back to the colonial era. Notably, the 1918 pandemic, often referred to as the Spanish flu, is estimated to have claimed the lives of approximately 100 million people worldwide. In historical development, influenza outbreaks reappeared from 1957 to 2022 in Yogyakarta, Indonesia, Daegu, South Korea, and even the world. This study uses historical research methods to examine policies for handling influenza so people can take preventive measures to prevent it. The Korean and Indonesian sources used include the collections of Gouvernement Besluit, Staatsblad, Bijblad, Rijksblad, and contemporary newspapers and the Korean Archives will be accessed through the Korean government’s official website, namely, Guksaphyeonchanwiwonhwe (National Institute of Korea) as well as the Royal Notes archive: Collection of Joseon Wangjo Sillok, accompanied by primary sources through FGDs and interviews. This paper proves there has been a delay in the response from the Indonesian government to deal with influenza, in contrast to the South Korean government, which is quicker and more responsive in suppressing the bad implications of influenza.Sejarah wabah influenza dimulai pada era kolonial.

Published: April 2024

This study aims to analyze women’s political participation during the national movement. The movement period began the women’s movement to voice their political ideas towards independence.    The women’s political movement has long existed. Women have struggled to establish their existence since colonial times. Analysis of women’s participation efforts in the political field is described in three organizations from three cities, namely Batavia (Jakarta), Jogjakarta, and Medan, each through Perhimpoenan Kaoem Betawi representing regional organizations, Aisyiyah representing socio-religious organizations and Keoetamaan Isteri representing socio-political organizations. This research uses historical heuristics, criticism, interpretation, and historiography methods. The heuristic stage is carried out by searching for library sources, documents, and archives, and it is selected based on the source criticism carried out. The results show that the wishes and demands for women’s political participation have not been realized. The limited opportunities for women to sit in the Volksraad and direct competition with men were factors that did not directly result in women being involved in politics. Penelitian ini bertujuan untuk menganalisis partisipasi politik perempuan pada masa pergerakan nasional. Masa pergerakan mengawali gerakan perempuan untuk menyuarakan ide-ide politiknya menuju kemerdekaan. Gerakan politik perempuan sudah ada sejak lama. Perempuan telah berjuang untuk membangun eksistensinya sejak zaman kolonial. Analisis terhadap upaya partisipasi perempuan dalam bidang politik digambarkan pada tiga organisasi dari tiga kota, yaitu Batavia (Jakarta), Jogjakarta, dan Medan, masing-masing melalui Perhimpoenan Kaoem Betawi yang mewakili organisasi daerah, Aisyiyah yang mewakili organisasi sosial keagamaan, dan Keoetamaan Isteri yang mewakili organisasi sosial-keagamaan. organisasi politik. Penelitian ini menggunakan metode sejarah yang terdiri atas heuristik, kritik, interpretasi, dan historiografi. Tahap heuristik dilakukan dengan mencari sumber perpustakaan, dokumen, dan arsip, serta dipilih berdasarkan kritik sumber yang dilakukan. Hasilnya menunjukkan bahwa keinginan dan tuntutan partisipasi politik perempuan belum terwujud. Terbatasnya kesempatan perempuan untuk duduk di Volksraad dan persaingan langsung dengan laki-laki menjadi faktor yang tidak secara langsung menyebabkan perempuan terlibat dalam politik.

Published: April 2024

Diarrhea and dehydration are significant health challenges in India, particularly among children. Here are some key points, Prevalence: Diarrhea is a leading cause of morbidity and mortality among children under five in India. The prevalence is higher in rural areas compared to urban areas. Causes: Diarrhea is often caused by contaminated food or water, poor sanitation and hygiene practices, and inadequate access to healthcare. Dehydration: Diarrhea can lead to dehydration, which is particularly dangerous for children. Dehydration can occur quickly and can be life-threatening if not treated promptly. Children face lot of challenges due to the immature system and the changes that happen during their growth and development. Any illness adds up stress to them. Diarrheoa is the most common cause of mortality and morbidity in India. Most of the time its preventable and hence measures need to be taken by the health care professionals to prevent diaarhoe. Mass media communication is the best mode of communication to disseminate health information’s. Pediatric nurses need to address this issue as a top priority one. They need to empower the parents and community to initiate preventive measures so that the need for hospitalization may be prevented or minimized.

An analysis of factors influencing the popularity and user satisfaction of hypertension self-management applications: a cross-sectional study in China
Authors: Ren Tingwei , He Ye , Zhang Yong
Published: April 2024

Background: As the largest developing country in the world, China lacks data on the content and popularity of smartphone self-management apps for HTN. The major functional characteristics and consumer interaction metrics of smartphone apps are unknown. This is the first study to provide an evaluation of Chinese smartphone-based self-management apps for hypertension in user angle. We analyzed the Chinese Android and iPhone markets using the search terms ‘‘hypertension’’ and “high blood pressure’’ in July 2018. All search items were screened according to inclusion and exclusion criteri Fifty-six of the apps included (47.9%) were designed for the Apple iPhone, and 61 (52.1%) were designed for Android devices. Moreover, 93.2% were used for blood pressure (BP) self-monitoring, 17.1% were used for diet self-monitoring, and 48.7% were used for physical activity self-monitoring. Similarly, 58.1% were capable of tracking other health data, and 49.6% had the ability to enhance medication adherence. Only 3.4% could transform the smartphone into a medical device for the measurement of BP. There were no differences in app features between the two smartphone platforms. Android apps, which were capable of both physical activity self-monitoring (odds ratio, 6.31; P <. 001) and diet self-monitoring (odds ratio, 3.18; P <. 001), had high popularity. There was no significant correlation between the major functional characteristics of all apps with high user satisfaction. Future work will propose a new methodology for evaluating the quality and reliability of smartphone apps for HTN self-management from the perspective of healthcare professionals (HCPs).
Factors affecting uptake of prevention of mother to child transmission of HIV by women attending antenatal clinic in Pumwani Maternity Hospital, Nairobi, Kenya
Authors: Ndonga Esther , MN Matu
Published: April 2024

Objective Mother-to-child transmission (MTCT) occurs when a woman with Human Immunodeficiency Virus (HIV) passes the virus to her unborn baby. Many health institutions have initiated programs on Preventions of Mother-to-Child Transmission of HIV (PMTCT), however the uptake of these services is still low. The purpose of the study was to determine factors that contribute to low uptake of PMTCT by women attending antenatal clinic in Pumwani Maternity Hospital, Kenya. Methods This was a hospital-based cross sectional study enrolling 161 antenatal (ANC) mothers aged between 18-49years. Data was collected using a semi-structured pre-tested questionnaire. Data was recorded and analyzed for significance at p<0.05 level of significance using Fisher Exact and Chi square for categorical data and logistic regression for comparing PMTCT uptake and independent variables. Results The mean age of the participants was 27years (range, 18-39years). Among the women, 85% were married, 91% belonged to a religious group and 99% had attended school. One hundred and thirty six (84%) women had been tested for HIV and 48(35%) of them were HIV-positive. Out of the 48 HIV positive women, 35(73%) had joined PMTCT. Religion was the only socio-cultural factor that was independently associated with PMTCT uptake. Knowledge of HIV and AIDS, MTCT and PMTCT was high among the women. Conclusion PMTCT uptake was high with quality of counseling being considered as good. The study encourages religious leader’s participation in PMTCT and preventive activities for HIV transmission.
Change in Slag Composition and Sulfur Content of Hot Metal in the Process Chain of Blast Furnace — Hot Metal Desul furization Complex — Converter (BOF)
Authors: SHEVCHENKO A. , KYSLIAKOV V. , DVOSKIN B. , MANACHYN I.
Published: April 2024

Introduction. Modern conditions of iron and steel making industry require production of high-quality competitive metal products. Thus, the removal of sulfur at the lowest cost has been becoming increasingly important.Problem Statement. The major amount of sulfur in iron and steel making comes with charge materials in sintering blast furnace production. When using out-of-furnace processing of hot metal in hot metal desulfurizationand slag removal facilities, the degree of hot metal desulfurization can be 75—99%. This ensures the production of hot metal with a sulfur content in the range of 0.002—0.015%.Purpose. The analysis of changes in the sulfur content of hot metal and in the slag composition in the processchain of steel production, followed by the development of technical solutions and process methods to eliminate theresulfurization of hot metal.Materials and Methods. Our calculations, based on the actual data of Ukrainian and Chinese iron and steelmaking facilities. The selected samples of slag and hot metal have been analyzed with the use of raster spectralmicroscopy methods. In the studies of sulfur content at various stages of smelting, the method of material balancecalculation has been employed.Results. In the slag phase, along with systems of CaO ∙ SiO2 ∙ Al2O3 type with diff erent ratios of componentscontaining 0.2—3.5% sulfur, CaxSiyAlz type systems containing up to 1% sulfur have been detected. In the beads, the sulfur content varies within 0.1—0.85%. Sulfur is present in the form of sulfi des of (Fe, Mn)S type, mainlyMnS, while in non-metallic inclusions of the beads, the sulfur content ranges within 15—30%. The residing ladleslag after desulfurization should not exceed 0.5—0.7 kg/t of hot metal.Conclusions. To prevent the resulfurization of hot metal during its discharge from a blast furnace, it is advisable to rationalize ladle slag modes, by adjusting ladle slag composition, increasing the degree of ladle cleaning from the slag residing from previous loads and inducing a slag cover in the absence of ladle slag. The conducted studies have shown that sulfur from the slag does not return to the hot metal and resulfurization does not occur, which is explained by the protective eff ect of residual magnesium.
Evaluating the Efficiency of Using Coherent-Type Nozzles for the Conditions of Additional Postcombustion of CO to CO2 in the Wor king Space of the Oxygen Converter
Authors: GOLUB T. , MOLCHANOV L. , SEMYKIN S. , VAKULCHUK V.
Published: April 2024

Introduction. The requirements for the working conditions of metallurgical industry have been becoming stricter, both in terms of increasing the process indicators and in terms of environmental friendliness of processes.Problem Statement. The main controlling factor of the oxygen-converter process is the oxygen jet supplied through the nozzles of the top lance. The main task of the process is the active mixing for refi ning and the provision of conditions for the postcombustion of CO to СО2 in off -gases to additionally increase the heat content of the bath in order to enable increasing scrap processing, which improves the environmental friendliness of the process. In electrometallurgy, to solve the problem of deep mixing, it has been proposed to use nozzles of the coherent type (like a cylinder in a cylinder, through which oxidizing and protective gases are supplied).Purpose. To study and to establish the features of using nozzles of the coherent type for the conditions of top oxygen purging in the converter.Materials and Methods. Samples of laboratory nozzles of the coherent type, which diff er in the ratio of the central and peripheral parts (75, 50, 25%) with respect to the force of the jet, have been studied with the use of a modifi ed liquid manometer; by two-phase cold modeling; by evaluating the degree of afterburning of CO-containing gases in comparison with the performance parameters of an equivalent cylindrical nozzle.Results. It has been established that the force with which the jet fl owing out of the nozzle acts on the liquid is signifi cantly less when that in the case of coherent type nozzles and decreases as the share of the peripheral part of the nozzle increases. According to the results of two-phase cold modeling, it has been noted that the use of coherent type nozzles contributes to the active formation of a foamed emulsion and increases the activity of mixing two-phase liquids during top blowing. The use of the coherent-type nozzles with a peripheral part of 75% increases the postcombustion of CO-containing gases by 42.36%.Conclusions. According to the obtained results, it is possible to recommend the use of nozzles of the coherent type to replace the cylindrical nozzles of oxygen lances, which perform the function of additional sources of infl uence on the bath and for the oxidation of CO in the waste gases.

Published: April 2024

Introduction. The study of the parameters of the clothing space is extremely important in the development of seasonal clothing for the military, police, athletes, etc.Problem Statement. The use of “smart” textiles capable of responding to changes in the environment, adapting to it by integrating functional capabilities into the textile structure, deserves attention. Person’s feeling and emotional response are accompanied by electrical, thermal, chemical or other changes in the human body, which can be recorded by electronic devices and used to monitor the comfort of clothing.Purpose. The purpose is to develop a functional system for monitoring the interlayer space of clothing given the temperature and relative humidity and for creating a prototype remote control system for clothing.Materials and Methods. Sensors (a microcontroller with a battery, radio modules, temperature and relative humidity sensors) placed in the knitted structure of the T-shirt, on certain parts of the human body have been used. Atmega328 microcontroller equipped with 18650 batteries has been employed to detect the temperature and the relative humidity in the interlayer space of the clothing with the help of DS18B20 temperature sensors and DHT22 humidity sensors. The HC-12 radio module has been used for transmitting the data from the microcontroller to the target device.

Phytoecia tigrina Mulsant (1851) is recognized as a species under strict protection EU Habitat Directive, it represents a focal point for conservation efforts across Europe. However, the dearth of comprehensive understanding regarding its biology, ecology, and geographical distribution poses formidable challenges to conservation endeavors. In the current study, we have delineated eight European and two Asian distinct metapopulations of Ph. tigrina across its geographic range, with a particular emphasis on elucidating its dispersion within the Circum-Carpathian region. This delineation serves to underscore the species' distribution, niche dimensions and limits of ecological tolerance that illuminate its adaptation capacity to diverse environmental conditions within the range. Our study has unveiled notable differentials in both morphological and ecological traits among Ph. tigrina metapopulations, notably between those located on the eastern and western flanks of the Carpathian Arc. Such differentials suggest the influence of divergent evolutionary trajectories, likely influenced by historical climatic changes during the Late Pleistocene and Holocene epochs. Significantly, specimens derived from eastern metapopulations exhibit morphological features of sufficient magnitude to warrant the proposition of a distinct subspecies, Phytoecia (Pilemia) tigrina podillica ssp. nov. This taxonomic delineation underscores the taxonomic complexity inherent within the Ph. tigrina species complex. Our investigations have further illuminated the historical dynamics of the species distribution, indicating the presence at least of two refugia during the Last Glacial Maximum (LGM). These refugial enclaves, situated in the Sea of Marmara/Eastern Aegean Sea region and the Pannonian Plain, likely played pivotal roles in shaping contemporary distributional patterns. Moreover, our ecological niche modeling endeavors have elucidated rapid expansions of suitable habitat for Ph. tigrina during post-glacial epochs, notably the Preboreal and Boreal periods. These expansions aligned with the rapid dispersion of its host plant Cynoglottis barrelieri supplying colonization of new territories in the face of the fast-changing post-glacial environment. Our study underscores the intricate interplay between evolutionary history, environmental dynamics, and imperatives for conservation Ph. tigrina. By elucidating these complexities, we endeavor to furnish a robust foundation for future conservation initiatives aimed at safeguarding this emblematic species and its associated habitats.

Heracleum sosnowskyi is an invasive transformer species dangerous for biodiversity and human health. The materials for this study were the standard geobotanical descriptions made on the territory of Ukrainian Polissia in the period from 2004 to 2022. The relevés were classified using the Braun-Blanquet methods and used for synphytoindication evaluation of the environmental factors, rating ecofactors, estimated based on the ecological scales of the species that form a phytocoenosis. Heracleum sosnowskyi was observed to occur in plant communities belonging to 13 classes, 16 orders, 21 alliances, and 29 associations. According to the synphytoindication, it most often grew in mesophyte, hemihydrocontrasthophobic (moderately moistened habitats that are sporadically moistened), subacidophilic, semieutrophic, acarbonataphilic, nitrophilic, hemiaerophobic (moderately aerated habitats), submicrothermal (habitats that receives 20–30 kc/sm2), subombrophytic, hemioceanic, subcryophytic (habitats with the average temperature of the coldest month of the year is approximately –8), semi-illuminated, euhemerobic (habitats that have been altered or created by humans and are under anthropogenic influence) habitats. The competitive advantages of Sosnowsky's hogweed over the native species are the combination of the ability to change r and K strategies, depending on the environmental conditions, with the production of a large number of seeds that are dispersed from a tall peduncle, maintaining a significant germination rate for several years, and allelopathy and efficient assimilation of nitrogen compounds, which helps it to increase the size of the shoot. Ruderal and natural grass ecosystems are the most vulnerable to the penetration of H. sosnowskyi in the early stages of autogenic succession (value of natural dynamic was 3.0–4.0 points). The highest projective cover and the density of its population were observed in the nitrified forest edges of associations Elytrigio repentis-Aegopodietum podagrariae var. Heracleum sosnowskyi (value of natural dynamic was 4.0–7.0 points). Forest ecosystems with multi-tiered vegetation (value of natural dynamic was above 9.5 points) and meadows with thorough sod (value of natural dynamic was above 4.8 points) were less vulnerable to invasions. At the same time, disruptions of the completeness of the tree stand or the integrity of sod created additional opportunities for the species to invade the territory. Once penetrating into natural or ruderal ecosystems, H. sosnowskyi most often transforms their autotrophic blocks into a variant of association Agropyretum repentis var. Heracleum sosnowskyi of class Artemisietea vulgaris, which is a more favorable phytocenosis for its intensive reproduction and spread. The results of the study can be used to prevent the spread of H. sosnowskyi.

Published: April 2024

The aim of the study was to model the territorial distribution and statistical assessment of migration through the trophic chain of naturally occurring radionuclides released into the environment as a result of uranium ore mining. Statistical, geoinformation and experimental research methods were used in the study. Interpolation of the results of volumetric activity of natural radionuclides in environmental components and development of spatial models of their territorial distribution were performed using the ArcGIS software; statistical processing of modelling results and development of mathematical models of migration of natural radionuclides between environmental components were performed using ArcGIS Geostatistical Analyst software. The paper substantiates the choice of the method of geostatistical modelling of the territorial distribution of volumetric activity of natural radionuclides 234U, 238U, 210Po, 210Pb, 226Ra in soils and plants, which allows modelling the values of probabilistic indicators of radioecological contamination in the absence of a sufficient array of initial actual research results. Based on the analysis of the data obtained, the methodology of mathematical modelling of migration of natural radionuclides between soil and plant parts was further developed, which will facilitate consideration of the specifics of migration of natural radionuclides through the trophic chain and help in determining the level of radioecological hazard to the environment. The developed territorial models allow one to obtain stochastic data for their further analytical processing and visualizing radioecological hazard zones. Based on the developed models, zones of increased radioecological hazard within the existing sources of radioactive contamination were identified.

Published: April 2024

Telehealth, the use of telecommunications technology and electronic information to aid in healthcare delivery, has revolutionized patient care. Health communities have already approved telemedicine for treating certain acute and chronic diseases, while teledentistry has emerged as a distinct field within the broader scope of telemedicine. Numerous trials have demonstrated the value of teledentistry in reducing dental expenses and expanding dental care access to remote and rural areas. With technological advancements, teledentistry holds the potential to further enhance dental services and patient care. The COVID-19 pandemic has brought healthcare to the forefront of public concern. The need for close face-to-face contact with patients largely led to the suspension of dentistry services. However, the increased use of cell phones and related software packages integrated into "teledentistry" has facilitated easier clinical data exchange between patients and clinicians. This technology proved invaluable for dentists managing dental emergencies during lockdowns, providing an innovative means to resume dental practice. As a result, integrating teledentistry into routine dental practice as a complement to the existing dental system is advisable. It has the potential to revolutionize dental care for the better by expanding access to care and decreasing expenses. Given these circumstances, this review discusses the value and implications of teledentistry, highlighting its potential as a game-changing solution for the dental industry.
