Disinformation and Sexual and Gender Diversity in Spain: Twitter Users’ Response, and the Perception of LGBTQI+ Organisations
Authors: Carratalá Adolfo
Published: April 2023

Increased disinformation has been able to flourish in the digital environment. Much of the fake news that circulate social networks is directed against vulnerable groups, such as the LGBTQI+ community. These contents often include hate speech, which has recently experienced a notable increase in Spain. Based on a quantitative and qualitative methodology, the purpose of this research study was, first, to explore the social audience’s reaction to four pieces of pseudo-information against LGBTQI+ people posted on Twitter by Mediterráneo Digital between 2018 and 2020, to determine the extent to which this content was considered true or rejected by users of this social network through their comments (N = 596). The four selected publications were considered fake news by recognised verification platforms. Secondly, in addition to the above analysis, six in-depth interviews were carried out with representatives of Spanish LGBTQI+ organisations to explore their perception of this situation and how they addressed disinformation. The results indicated that a high percentage of the responses posted on Twitter consider disinformation against this social group to be true, although a significant proportion of comments also intervened in the conversation to reject these messages. Activists believed pseudo-media (websites that try to imitate conventional news sites but do not respect the diligence and principles of journalism), and social networks are largely responsible for the increase in disinformation, and considered the production of truthful information, educational actions, and collaboration with other groups to be successful strategies in combating disinformation.
Anisotropy Analysis of the Permeation Behavior in Carbon Dioxide-Assisted Polymer Compression Porous Products
Authors: Aizawa Takafumi
Published: April 2023

The carbon dioxide-assisted polymer compression method is used to create porous polymer products with laminated fiber sheets that are crimped in the presence of carbon dioxide. In this method, fibers are oriented in the sheet-spread direction, and the intersections of the upper and lower fibers are crimped, leading to several intersections within the porous product. This type of orientation in a porous material is anisotropic. A dye solution was injected via a syringe into a compression product made of poly(ethylene terephthalate) nonwoven fabric with an average fiber diameter of 8 μm. The anisotropy of permeation was evaluated using the aspect ratio of the vertical and horizontal permeation distances of a permeation area. The aspect ratio decreased monotonically with decreasing porosity; it was 2.73 for the 80-ply laminated product with a porosity of 0.63 and 2.33 for the 160-ply laminated product with a porosity of 0.25. A three-dimensional structural analysis using X-ray computed tomography revealed that as the compression ratio increased, the fiber-to-fiber connection increased due to the increase in adhesion points, resulting in decreased anisotropy of permeation. The anisotropy of permeation is essential data for analyzing the sustained release behavior of drug-loaded tablets for future fabrication.

Emerging contaminants are produced globally at high rates and often ultimately find their way into the aquatic environment. These include substances contained in anti-seizure medication (ASM), which are currently appearing in surface waters at increasing concentrations in Germany. Unintentional and sublethal, chronic exposure to pharmaceuticals such as ASMs has unknown consequences for aquatic wildlife. Adverse effects of ASMs on the brain development are documented in mammals. Top predators such as Eurasian otters (Lutra lutra) are susceptible to the bioaccumulation of environmental pollutants. Still little is known about the health status of the otter population in Germany, while the detection of various pollutants in otter tissue samples has highlighted their role as an indicator species. To investigate potential contamination with pharmaceuticals, Eurasian otter brain samples were screened for selected ASMs via high-performance liquid chromatography and mass spectrometry. Via histology, brain sections were analyzed for the presence of potential associated neuropathological changes. In addition to 20 wild otters that were found dead, a control group of 5 deceased otters in human care was studied. Even though none of the targeted ASMs were detected in the otters, unidentified substances in many otter brains were measured. No obvious pathology was observed histologically, although the sample quality limited the investigations.

Published: April 2023

The distribution of vanadium (V) in aerosols is commonly used to track ship exhaust emissions, yet the atmospheric abundance of V has been greatly reduced due to the implementation of a clean fuel policy. Recent research mainly discussed the chemical compositions of ship-related particles during specific events, yet few studies focus on the long-term changes of V in the atmosphere. In this study, a single-particle aerosol mass spectrometer was used to measure V-containing particles from 2020 to 2021 in Huangpu Port in Guangzhou, China. The long-term trend of the particle counts of V-containing particles declined annually, but the relative abundance of V-containing particles in the total single particles increased in summer due to the influence of ship emissions. Positive matrix factorization revealed that in June and July 2020, 35.7% of the V-containing particles were from ship emissions, followed by dust and industrial emissions. Furthermore, more than 80% of the V-containing particles were found mixing with sulfate and 60% of the V-containing particles were found mixing with nitrate, suggesting that the majority of the V-containing particles were secondary particles processed during the transport of ship emissions to urban areas. Compared with the small changes in the relative abundance of sulfate in the V-containing particles, the relative abundance of nitrate exhibited clear seasonal variations, with a high abundance in winter. This may have been due to the increased production of nitrate from high concentrations of precursors and a suitable chemical environment. For the first time, the long-term trends of V-containing particles in two years are investigated to demonstrate changes in their mixing states and sources after the clean fuel policy, and to suggest the cautious application of V as an indicator of ship emissions.

Published: April 2023

Bisphenol A (BPA) is a major component of polycarbonate plastics and epoxy resins. While many studies have investigated the effect BPA exposure has upon changes in gut microbial communities, the influence of gut microbiota on an organism’s ability to metabolize BPA remains comparatively unexplored. To remedy this, in this study, Sprague Dawley rats were intermittently (i.e., at a 7-day interval) or continuously dosed with 500 μg BPA/kg bw/day for 28 days, via oral gavage. In the rats which underwent the 7-day interval BPA exposure, neither their metabolism of BPA nor their gut microbiota structure changed greatly with dosing time. In contrast, following continuous BPA exposure, the relative level of Firmicutes and Proteobacteria in the rats’ guts significantly increased, and the alpha diversity of the rats’ gut bacteria was greatly reduced. Meanwhile, the mean proportion of BPA sulfate to total BPA in rat blood was gradually decreased from 30 (on day 1) to 7.4% (by day 28). After 28 days of continuous exposure, the mean proportion of BPA glucuronide to total BPA in the rats’ urine elevated from 70 to 81%, and in the rats’ feces the mean proportion of BPA gradually decreased from 83 to 65%. Under continuous BPA exposure, the abundances of 27, 25, and 24 gut microbial genera were significantly correlated with the proportion of BPA or its metabolites in the rats’ blood, urine, and feces, respectively. Overall, this study principally aimed to demonstrate that continuous BPA exposure disrupted the rats’ gut microbiota communities, which in turn altered the rats’ metabolism of BPA. These findings contribute to the better understanding of the metabolism of BPA in humans.

Published: April 2023

Health risks caused by stings from Vespa velutina nigrithorax (VV), also known as the yellow-legged Asian hornet, have become a public concern, but little is known about its venom composition. This study presents the proteome profile of the VV’s venom sac (VS) based on Sequential Window Acquisition of all Theoretical Mass Spectra (SWATH-MS). The study also performed proteomic quantitative analysis and examined the biological pathways and molecular functions of the proteins in the VS of VV gynes (i.e., future queens [SQ]) and workers [SW]. The total protein content per VS was significantly higher in the SW than in the SQ (274 ± 54 µg/sac vs. 175 ± 22 µg/sac; p = 0.02). We quantified a total of 228 proteins in the VS, belonging to 7 different classes: Insecta (n = 191); Amphibia and Reptilia (n = 20); Bacilli, γ-Proteobacteria and Pisoniviricetes (n = 12); and Arachnida (n = 5). Among the 228 identified proteins, 66 showed significant differential expression between SQ and SW. The potential allergens hyaluronidase A, venom antigen 5 and phospholipase A1 were significantly downregulated in the SQ venom.

Introduction: During the first two years of the COVID-19 pandemic, Australia implemented a series of international and interstate border restrictions. The state of Queensland experienced limited COVID-19 transmission and relied on lockdowns to stem any emerging COVID-19 outbreaks. However, early detection of new outbreaks was difficult. In this paper, we describe the wastewater surveillance program for SARS-CoV-2 in Queensland, Australia, and report two case studies in which we aimed to assess the potential for this program to provide early warning of new community transmission of COVID-19. Both case studies involved clusters of localised transmission, one originating in a Brisbane suburb (Brisbane Inner West) in July–August 2021, and the other originating in Cairns, North Queensland in February–March 2021. Materials and Methods: Publicly available COVID-19 case data derived from the notifiable conditions (NoCs) registry from the Queensland Health data portal were cleaned and merged spatially with the wastewater surveillance data using statistical area 2 (SA2) codes. The positive predictive value and negative predictive value of wastewater detection for predicting the presence of COVID-19 reported cases were calculated for the two case study sites. Results: Early warnings for local transmission of SARS-CoV-2 through wastewater surveillance were noted in both the Brisbane Inner West cluster and the Cairns cluster. The positive predictive value of wastewater detection for the presence of notified cases of COVID-19 in Brisbane Inner West and Cairns were 71.4% and 50%, respectively. The negative predictive value for Brisbane Inner West and Cairns were 94.7% and 100%, respectively. Conclusions: Our findings highlight the utility of wastewater surveillance as an early warning tool in low COVID-19 transmission settings.
Using Google Trends to Estimate the Geographic Distribution of Soil-Transmitted Helminthiasis in the United States from 2016 to 2021
Authors: Adams Steven H. , Endy Timothy P. , Larsen David A.
Published: April 2023

Soil-transmitted helminth infections are assumed to be uncommon in the US, despite numerous studies in the past few decades showing high burdens in Appalachia and the southern states. We assessed trends of interest in the Google search engine to gauge spatiotemporal patterns of potential soil-transmitted helminth transmission. We conducted a further ecological study comparing Google search trends to risk factors for soil-transmitted helminth transmission. Google search trends for terms related to soil-transmitted helminths were clustered in Appalachia and the south, with seasonal surges suggestive of endemic transmission for hookworm, roundworm (Ascaris), and threadworm. Furthermore, lower access to plumbing, increased septic tank use, and more rural environments were associated with increased soil-transmitted helminth-related Google search terms. Together, these results suggest that soil-transmitted helminthiasis remains endemic in parts of Appalachia and the south.

Background: Chikungunya virus (CHIKV) diagnosis has become a challenge for primary care physicians in areas where the Zika virus and/or Dengue virus are present. Case definitions for the three arboviral infections overlap. Methods: A cross-sectional analysis was carried out. A bivariate analysis was made using confirmed CHIKV infection as the outcome. Variables with significant statistical association were included in an agreement consensus. Agreed variables were analyzed in a multiple regression model. The area under the receiver operating characteristic (ROC) curve was calculated to determine a cut-off value and performance. Results: 295 patients with confirmed CHIKV infection were included. A screening tool was created using symmetric arthritis (4 points), fatigue (3 points), rash (2 points), and ankle joint pain (1 point). The ROC curve identified a cut-off value, and a score ≥ 5.5 was considered positive for identifying CHIKV patients with a sensibility of 64.4% and a specificity of 87.4%, positive predictive value of 85.5%, negative predictive value of 67.7%, area under the curve of 0.72, and an accuracy of 75%. Conclusion: We developed a screening tool for CHIKV diagnosis using only clinical symptoms as well as proposed an algorithm to aid the primary care physician.

Published: April 2023

The 2018 United Nations High-Level Meeting on Tuberculosis (UNHLM) set targets for case detection and TB preventive treatment (TPT) by 2022. However, by the start of 2022, about 13.7 million TB patients still needed to be detected and treated, and 21.8 million household contacts needed to be given TPT globally. To inform future target setting, we examined how the 2018 UNHLM targets could have been achieved using WHO-recommended interventions for TB detection and TPT in 33 high-TB burden countries in the final year of the period covered by the UNHLM targets. We used OneHealth-TIME model outputs combined with the unit cost of interventions to derive the total costs of health services. Our model estimated that, in order to achieve UNHLM targets, >45 million people attending health facilities with symptoms would have needed to be evaluated for TB. An additional 23.1 million people with HIV, 19.4 million household TB contacts, and 303 million individuals from high-risk groups would have required systematic screening for TB. The estimated total costs amounted to ~USD 6.7 billion, of which ~15% was required for passive case finding, ~10% for screening people with HIV, ~4% for screening household contacts, ~65% for screening other risk groups, and ~6% for providing TPT to household contacts. Significant mobilization of additional domestic and international investments in TB healthcare services will be needed to reach such targets in the future.
Recent Quarkonia Measurements in Small Systems at RHIC and LHC Energies
Authors: Smith Krista L.
Published: April 2023

Heavy-ion research at the Relativistic Heavy Ion Collider (RHIC) during the first decade of data collection, approximately during the years 2000–2010, was primarily focused on the study of Au+Au collisions. The search for evidence of quark-gluon plasma (QGP), a state of matter where quarks and gluons become unbound within a high energy density environment, which was at the forefront of research efforts. However, studies of the azimuthal anisotropy parameter v2 in p/d+Pb collisions from the Large Hadron Collider (LHC) yielded results consistent with the hydrodynamic flow, one of the signatures of quark-gluon plasma formation in heavy-ion collisions. Since the publication of these findings, the field of heavy-ion physics has made subsequent measurements in small system collisions to study cold nuclear matter effects as well as look for additional evidence of hot nuclear matter effects. Quarkonia, a bound state of a cc¯ or bb¯ pair, has often been used to probe a wide range of nuclear effects in both large and small collision systems. Here we will review recent quarkonia measurements in small system collisions at RHIC and LHC energies and summarize the experimental conclusions.

Prostate cancer is the most frequently diagnosed cancer in men in the United States. Among the different available treatment options, radiation therapy is recommended for localized or even advanced disease. Erectile dysfunction (ED) often occurs after radiation therapy due to neurological, vascular, and endocrine mechanisms resulting in arterial tone alteration, pudendal-nerve neuropraxia, and lastly fibrosis. Considering the influence of quality of life on patients’ treatment choice, radiation-therapy-induced ED prevention and treatment are major issues. In this narrative review, we briefly summarize and discuss the current state of the art on radiation-therapy-induced ED in PCa patients in terms of pathophysiology and available treatment options.
Nature in the Heart and Mind of the Beholder: Psycho-Emotional and EEG Differences in Perception of Virtual Nature Due to Gender
Authors: Davidov Artem , Razumnikova Olga , Bakaev Maxim
Published: April 2023

Natural environment experiences in virtual reality (VR) can be a feasible option for people unable to connect with real nature. Existing research mostly focuses on health and emotional advantages of the “virtual nature” therapy, but studies of its neuropsychological effects related to visual perception are rare. In our experiment, 20 subjects watched nature-related video content in VR headsets (3D condition) and on a computer screen (2D condition). In addition to the gender factor, we considered the individual Environmental Identity Index (EID) and collected the self-assessment of the emotional state per the components of Valence, Arousal, and Dominance in each experimental condition. Besides the psychometric data, we also registered brainwave activity (EEG) and analyzed it with the 7 frequency bands. For EID, which was considerably higher in women, we found significant positive correlation with Valence (i.e., beneficial effect of the natural stimuli on the psycho-emotional status). At the same time, the analysis of the EEG data suggests a considerable impact of the VR immersion itself, with higher relaxation alpha effect in 3D vs. 2D condition in men. The novel and most pronounced effect of the gender factor was found in the relation between the EID and the EEG powers in the high-frequency bands—that is, positive correlation of these variables in women (0.64 < Rs < 0.74) but negative correlation in men (−0.66 < Rs < −0.72). Our results imply individually different and gender-dependent effects of the natural stimulus in VR. Correspondingly, the video and VR content development should consider this and aim to provide a user characteristics-tailored experience.
The concept of preventive care in the pediatric population with risk factors for the malocclusion development and prevention of severe malocclusion in children aged 3-12 years old
Authors: Shishmareva A. S. , Bimbas E. S.
Published: April 2023

Relevance. Malocclusion prevention in Russian children is an urgent medical and social problem. The results of Russian epidemiological studies show malocclusion prevalence and severity increase in children with age. Postgrowth orthodontic treatment is costly and often inaccessible for the most population. In the current situation, malocclusion prevention organization in children is one of the most important tasks of public healthcare.

Purpose. To propose and substantiate a new model for the prevention of severe malocclusion in children.

Materials and methods. We have created a new conceptual model for the prevention of severe malocclusion in children to develop a methodology that provides unified approaches to malocclusion prevention.

Results. The model involves the construction of a two-level system of pediatric preventive care based in the city, municipal multidisciplinary dental clinics. The model novelty is determined by the new concept of the primary prevention of malocclusion and early orthodontic treatment (EOT) processes to prevent severe malocclusion (secondary prevention) as a single system that provides a positive result in maxillofacial development in children. The introduction of a pediatric dentist as an operator and a coordinator of the prevention program implementation into the structure of preventive care for children's malocclusion determines the novelty of the prevention system conceptual model. The proposed conceptual model prioritizes an orthodontist who provides secondary prevention of severe malocclusion by early orthodontic treatment (EOT) to children during the growth and development of malocclusions. The introduction of a malocclusion assessment to identify the EOT need score also determines the novelty of the malocclusion secondary prevention subsystem. The model places a high value on the management function/ management issues. Severe malocclusion prevention program implementation in children requires changing the paradigm of doctors, namely, pediatric dentists and orthodontists.

Conclusion. The presented concept of the two-level malocclusion prevention organization (primary prevention of malocclusion in toddlers and preschoolers and secondary prevention of severe malocclusion by EOT in children aged 3-12 years) will allow for the reduction of the number of severe malocclusions during dental and facial development and for the need of complex treatment at later stages, will contribute to children health preservation, their social adaptation and the child and family quality of life increase.

Relevance. The guided bone regeneration (GBR) technique during dental implant treatment, if alveolar bone/part of the jaws is lost, stands out for its effective potential, the main factor of which is the possibility of the necessary bone volume restoration having morphofunctional signs of organotypicity. The prognosis effectiveness of such reconstruction outcome directly depends on the wound process characteristics. The variability of the latter, subject to an unbiased quantitative assessment, can be essential for predictive analysis and prognosis.Aim. The study aimed to develop a technique for quantitative assessment of surgical wound healing (exemplified with an extracted tooth socket), described in the first part of the publication.Materials and methods. The clinical study involved 20 patients of both sexes diagnosed with the condition after dental implantation and reconstruction of the alveolar bone volume using the GBR technique modified by the formation of a situational vicryl framework (SVF). We determined the following parameters: independent and dependent variables, with their indirect mutually dependent influence on a favourable, compromised or unfavourable treatment outcome, based on the wound healing process follow-up and assessment of immediate results in the early, middle and late postoperative period − up to 1 month, and the analysis of delayed – from 1 month to 1 year, and long-term – over one year. These variables are characterized as quantitative indicators – biomarkers, processed by the correlation and regression analysis using the Gretl statistical package.Results. The study revealed a direct correlation regarding all parameters as independent (factor) and dependent (effect) variables necessary for quantifying the wound healing process variability. The created linear regression model confirmed the empirically observed and theoretically substantiated idea of the reciprocal influence of normal and pathological variations of wound healing process on an outcome of dental implantation in the reconstruction of the alveolar bone defect. The correlation and regression analysis for an unbiased quantitative assessment of surgical wound healing demonstrated the statistically explicable behaviour of dependent variables at a 95% le vel.Conclusion. The correlation and regression analysis performed using the presented data indicates a direct correlation between the parameters of a favourable, compromised and unfavourable outcome of dental implantation during the reconstruction of the alveolar bone volume using the GBR technique modified by the formation of SVF and variables expressed by biomarkers, such as the initial complexity of clinical conditions, duration of surgery, mechanical load of the wound, bio-reactive properties of the additional materials required in the w ound.
Customized in-vivo tissue engineering for bone grafting
Authors: Tarba I. I.
Published: April 2023

Relevance. Jaw bone volume restoration during dental implantation and reconstructive oral surgery is a relevant problem in modern dentistry. In recent years, the needs of daily dental practice determined the search for new osteoplastic materials with desired properties, including cellular technologies, to stimulate bone regeneration and accelerate bone repair processes.Materials and methods. The study used third molar area gingival specimens to create tissue-engineered constructs for bone matrix colonization, subject to in vitro expansion. Octacalcium-phosphate-based materials (OCP), used as the carrier matrix, were characterized by a larger particle surface area for a more developed microrelief, a bioresorption rate, and a hydrophilic surface. The finished tissue-engineered construct, consisting of multipotent mesenchymal stromal cells colonized on the matrix, was implanted into an artificially created tibial defect in 8 Chinchilla male rabbits. Animal experiments were conducted according to ethical standards. Rabbits were sacrificed on days 8 and 12 for histological testing.Results. In the early follow-up period (8 weeks), there were areas of mature bone with incorporated osteoblasts. Besides, there were areas of primary bone with adhesion lines. Later (12 weeks), such granules fully integrated into the diaphysis cortical part. The results showed the preservation of the low-mineralized bone girdle, osteoid - a bone substance formation precursor, between the octacalcium phosphate granule and the bone.Conclusion. The results of the experimental study allow us to conclude that the customized tissue-engineered construct developed by us contributes to bone grafting.

Authors: Akulovich A. V. , Nikiforova G. G. , Korostelev A. A. , Matelo S. K.
Published: April 2023

Relevance. Quantitative light-induced fluorescence (QLF) is widely used to diagnose the enamel condition during various dental interventions and allows for quick, objective and noninvasive assessment of the patient's oral hygiene status and follow-up of enamel de- and remineralization level.Materials and methods. The QLF technique used by the study increases the visual contrast between sound and diseased oral tissues when various (organic) substances in the mouth absorb light of a certain wavelength (different colours) and then re-emit the absorbed energy at a different wavelength. Filtration of illuminating light gives a fluorescent image or a QLF image. In a clinical setting, we used a QLF equipment set, namely, the Q-ray clinical software; Qraycam pro camera for full-arch imaging; Qraypen C intraoral camera; Qscan plus.Results. QLF was an additional tool for a practising dentist or dental hygienist, which allowed for the detection of the pathological process at the earliest stage, assisting in the diagnosis of the dental enamel condition, the detection of plaque without disclosing agents and assessment of its exact amount, contributing to the identification of hidden foci of enamel demineralization and carious lesions, cracks, tartar and oral hygiene evaluation.The analyzed data show the very high efficiency of the performed therapy with the 'R.O.C.S. medical 0+' remineralizing gel. The objective QLF data fully confirm the external elimination of white spots, and their almost complete disappearance is noted.Conclusion. Quantitative light-induced fluorescence and its parameters are essential not only for understanding the effectiveness of the applied techniques for bleaching, microabrasion, remineralization and other manipulations but also for their safety for dental enamel.
The effect of comorbidities on periodontal and hygiene indices, and oral fluid mineral composition
Authors: Matveeva E. V. , Antonova I. N. , Kipchuk A. V.
Published: April 2023

Relevance. In patients with comorbidities, the barrier resistance of periodontal tissues decreases due to oral homeostasis damage, which increases the severity of inflammatory periodontal diseases and needs the interaction of dentists and internists to develop common approaches to such patients' treatment and management.Aim. The study aimed to study the periodontal and oral hygiene indices and the oral fluid mineral composition in dental patients with comorbidity.Materials and methods. The study examined 63 dental patients with comorbidities: coronary artery disease, chronic gastritis, chronic nephritis, and chronic sinusitis. The Green-Vermillion oral hygiene index (OHI-S) detected the oral hygiene status, and the CPITN index of the WHO and the PMA index revealed the periodontal status. Electrothermal atomic absorption spectroscopy using QUANTUM.Z1 graphite furnace atomic absorption spectrometer determined the amount of calcium, magnesium, zinc and copper in the oral f luid.Results. Patients with coronary artery disease and chronic nephritis demonstrated a statistically significant decrease in oral hygiene associated with severe periodontal inflammation. Analysis of the oral fluid mineral composition showed that patients with coronary artery disease had decreased calcium, magnesium and zinc levels. The chronic nephritis patients had a copper and zinc decrease in the oral fluid. In patients with chronic gastritis, there was a lack of magnesium and copper in the oral fluid. The patients with chronic sinusitis showed a decrease in copper.Conclusions. Dental professionals should consider patient systemic diseases and oral fluid mineral composition at a dental appointment, during treatment and during preventive measures prescription.

La réception de la nomenclature binominale et la diffusion du linnéisme en France au XVIIIe siècle
Authors: Bange Christian
Published: April 2023

Lorsqu’il publia son Species plantarum en 1753, Linné proposa des noms binominaux (noms triviaux) pour l’indexation de chaque espèce, qui constituent la base de la nomenclature scientifique actuellement en usage en botanique et en zoologie. Malgré l’opposition de Buffon et d’Adanson envers Linné, ces noms latins ont été utilisés de plus en plus fréquemment par les naturalistes français au cours de la seconde moitié du XVIIIe siècle, même lorsqu’ils n’emploient pas les systèmes artificiels de classification élaborés par Linné. L’adoption des noms triviaux accompagna l’adhésion aux principes que Linné a énoncés pour l’étude de l’histoire naturelle et l’emploi de la terminologie. Les noms triviaux ont facilité la communication entre les naturalistes, y compris en dehors de la taxinomie, et ont pu s’accommoder de conceptions divergentes au sujet de la réalité des catégories taxinomiques.

Hydrophobic surfaces provide special characteristics for biomedical applications ranging from tunable protein adsorption, cellular interactions, and hemocompatibility to antibacterial coatings. In this research, we biomimic the hair-like micro-whisker structures of magnolia leaf using a synthetic polymeric formulation. Optical and scanning electron microscopy images revealed the presence of micro-whiskers resulting in higher water contact angles. The top layer of the magnolia leaf had a contact angle of 50º as compared to the hydrophobic bottom layer at 98º. A synthetic polymeric formulation was coated on different materials to study its effect on hydrophobicity. The coating was replicated (n=3) on each of the materials used such as glass, polymer, fabric, wood, and stainless steel. A surface tensiometer was used to measure the transition from hydrophilic to hydrophobic interactions between water and the substrate materials. Contact angle measurements revealed an increase in hydrophobicity for all the materials from their original uncoated surface. Glass displayed the highest increase in contact angle from 37º to 90º. Phase analysis of the coated region was performed to characterize the surface exposure of glass substrate to the synthetic polymeric formulation. An increase in the coated region showed a significant increase in contact angle from 50º to 95º. This research lays the foundation to develop and understand hydrophobic coatings for several biomedical applications including non-fouling implant surfaces, lab-on-chip devices, and other diagnostic tools.

Authors: Kutergin N.B. , Egorov D.E.
Published: April 2023

Проведен анализ девиантного поведения. Исследовано влияние занятий в спортивных секциях на формирование личности подростка. Цель исследования состоит не в анализе различных мнений по поводу девиантного поведения, а в исследовании влияния занятости молодежи и подростков в спортивных секциях на такое поведение. Представлены методические рекомендации и советы по результативности предотвращения девиантного поведения. Под девиантным поведением понимается не только отклонение от социальных общепризнанных общественных норм в отрицательную сторону, но и в положительную – положительная девиация. Молодые одаренные люди, в какой бы сфере они не были заняты, тоже отклоняются от нормы, это так называемая социально-позитивная девиация. Но чаще всего речь идет об отрицательной девиации – такой, когда поведение можно осудить с точки зрения как минимум общественной морали и нравственности, как максимум – с точки зрения несоблюдения ряда законов, в том числе и уголовного. Причины девиантного поведения у подростков различны, они заключаются в процессе социализации молодой личности. Социализация – процесс вхождения индивида в систему общественных отношений. На этот процесс оказывает влияние множество факторов, где подростковый возраст – занимает особое место.

Мета: дати порівняльну характеристику морфологічних особливостей, функціональних та психофізіологічних можливостей представників різних видів скелелазіння. Матеріал і методи. В дослідженні взяли участь 26 спортсменів, з них - 10 майстрів спорту міжнародного класу, що спеціалізуються в швидкісному лазінні, 10 майстрів спорту міжнародного класу, що спеціалізуються в лазінні на складність і 6 боулдерінгістів міжнародного класу. Методи дослідження: теоретичний аналіз і узагальнення літературних джерел, антропометричні методи дослідження  фізіологічні методи дослідження, педагогічне тестування, психофізіологічні методи дослідження, математико-статистичні методи. Результати. Виявлено, що довжина тіла достовірно вище у представників швидкісного лазіння і боулдерінгістів порівняно з представниками лазіння на складність; обхват стегна найбільший у представників швидкісного лазіння; за рівнем функціональної підготовленості найкращі показники у скелелазів, що спеціалізуються в лазінні на складність.  Виявлена факторна структура підготовленості скелелазів, що спеціалізуються в різних видах лазіння. Показана комплексність прояву фізичних якостей у взаємозв'язку з показниками морфофункціональних особливостей і психофізіологічних можливостей представників скелелазіння. Висновки. Виявлено, що різні види скелелазіння висувають різні вимоги до розвитку компонентів фізичної підготовленості: швидкісне лазіння більшою мірою сприяє розвитку вибухової сили і швидкісної витривалості, а лазіння на складність більшою мірою сприяє розвитку силової витривалості на тривалих тимчасових інтервалах. Боулдерінг сприяє розвитку вибухової сили та силової витривалості на коротких інтервалах часу.

Published: April 2023

Представлено теоретическое обоснование подходов к определению показателей мышечной силы человека при подъеме отягощений с целью выявления победителя. Приведен краткий исторический экскурс в этапы зарождения систем оценивания соревновательных дисциплин. Рассмотрены существующие варианты оценивания соревновательных достижений, проанализированы их основные характеристики и критерии оценки. В настоящее время предлагается разработанная система оценивания соревновательных достижений тяжелоатлетов, как мужского пола, так и женского пола с учетом их собственного веса, т.е. весового коэффициента. Это позволяет равноценно сопоставлять полученные результаты тяжелоатлетов. Данная система апробирована в ряде соревнований по тяжелой атлетике. Для более широкого использования предлагаемой методики оценивания соревновательных достижений тяжелоатлетов использована современная IT – технология. Может применяться в соревнованиях различного уровня и предлагаться как национальная система оценивания соревновательных достижений тяжелоатлетов. Одним из достоинств является возможность ранжирования тяжелоатлетов в разных номинациях. В качестве примера применения IT – технологии выполнены пошаговые действия для определения количества очков условного спортсмена, что значительно упрощает систему подведения итогов соревнований, определяет «абсолютного победителя». Методика получила положительные отзывы, внедряется в учебно-тренировочный процесс спортивными секциями по тяжелой атлетике ВУЗами г. Харькова.

Мета роботи складалася у виявленні фізичних та функціональних причин травматизму та ефективності застосування комплексної методики відновлення баскетболісток після травм опорно-рухового апарата. Матеріал і методи: В даному дослідженні прийняли участь 21 баскетболістка, з них 4 майстра спорту, 9 кандидатів в майстри спорту, 8 спортсменок 1 розряду. Методи дослідження: педагогічний метод суб'єктивної оцінки ваги навантаження й інтенсивності болючих відчуттів, фізіологічні методи дослідження (тест максимальної працездатності, ортостатична проба, визначення показників серцевого ритму, визначення показників роботи дихальної та серцево-судинної систем), методи педагогічного тестування, метод педагогічного експерименту, методи математичної статистики. Результати. Встановлено, що травматичність баскетболісток підвищується по мірі підвищення їх вагозростових показників. Це пов’язано з біомеханічними,  функціональними, психофізіологічними, ортостатичними та вегето-судинними особливостями людей різного зросту, а також -   вимогами гри, які підвищуються по мірі підвищення вагозростових показників спортсменок, що заставляє центрових та крайніх нападаючих постійно працювати на межі своїх можливостей і приводить до травматизму. Висновки. Застосування ефективних методів індивідуалізації навчально-тренувального процесу, одним з яких може служити метод контролю навантажень по суб’єктивним відчуттям, а також – ефективних методів профілактики та лікування травм.
