Chemical composition and bioactivities of Phellinus pini extracts, and quality evaluation of healthy drinks prepared from the mushroom
Authors: Ngan Nguyen , Nguyen Trang
Published: October 2024

Phellinus pini, a mushroom species found in East Asian countries, is commonly
consumed as a medicinal beverage known for its stomach-warming effects and
purported ability to alleviate pain and tumors. In this study, P. pini was
extracted using different methods (hot water, sonication, microwave, and
soaking). The extracts were analyzed for phenolic and polysaccharide
contents. Additionally, the extracts were evaluated for their antioxidant
potential and ability to inhibit albumin denaturation. The results
demonstrated that the extract obtained with hot water extraction contained
the greatest amount of phenolics (105.98 ? 0.53 mg GAE/mL). The hot water
and microwave extraction methods showed more effective in extracting
polysaccharide from the mushroom. Moreover, the extract from the ultrasound
extraction method presented the strongest antioxidant activity by scavenging
DPPH and ABTS radicals by 41.26 and 97.84 %, respectively while the hot
water extract exhibited the most potent ability to inhibit albumin
denaturation by 96.40 %. Among the four healthy drinks formulated, the
formulation with the greatest proportion of P. pini extract contained the
highest total phenolic content, antioxidant activity, and the most favorable
sensory overall liking. The findings deepen our understanding of the
chemical composition and potential health-promoting properties of P. pini,
as well as revealing new potential applications for the mushroom in the food
and nutraceutical industries.
Investigation of the bioactivities of Saponaria mesogitana methanolic extract along with its phytochemical composition
Authors: Ozay Cennet , Alkac Cerci , Temel Aybala , Pehlivan Melek
Published: October 2024

Saponaria species are known to contain saponins which have a wide variety of
biological activities. But up to now, the phenolic compounds of S.
mesogitana have not been clarified. Therefore, this study aimed to determine
the phenolic composition and some biological activities of S. mesogitana for
the first time. The antioxidant activities of the methanol and water
extracts were assessed using the DPPH, FRAP, and ?-carotene/linoleic acid
assays, while the total secondary metabolite content, including phenolics,
flavonoids, and saponins, was also determined for both extracts. Based on
the antioxidant activity and total phenolic and flavonoid contents, further
HPLC analysis, as well as anticancer and antimicrobial activity experiments,
were conducted using the methanol extract. The anticancer potential was
assessed using the MTT assay and wound healing migration test, while
antibacterial activity was evaluated through disc diffusion and MIC assays.
Additionally, the antibiofilm properties of the extract were examined using
the crystal violet method. The methanolic extract showed high antioxidant
activity, while caffeic acid and epicatechin were characterized as major
phenolic compounds by HPLC. S. mesogitana inhibited not only bacterial
growth but also the levels of migration of SHSY-5Y cancer cells. These
findings indicate that S. mesogitana possesses potent antioxidant,
anticancer, antimicrobial, and antibiofilm activities associated with its
bioactive phenolic constituents.

Published: October 2024

Objectives

To compare the biomechanics of labial and lingual fixed orthodontic treatment options for a simulated curve of Spee malocclusion.

Materials and Methods

An in vitro electromechanical orthodontic simulator was used to measure the three−dimensional forces and moments on each tooth of a mandibular arch. Labial and lingual brackets, both with 0.018−inch slot sizes, were bonded to mechanical teeth. Three archwire forms were considered: labial straight, lingual straight, and lingual mushroom. The simulator was set in a passive levelled position with 0.016−inch × 0.022−inch stainless steel archwires, then teeth were moved to a curve of Spee maloclussion with the first premolar intruded 1.5 mm and the canine and second premolar intruded 0.75 mm. Two−way mixed multivariate analysis of variance (α = 0.05) was used to compare forces and moments generated among the three archwires.

Results

Statistical differences were found in 55 of 63 comparisons of forces and moments between archwire types for each tooth around the arch. The lowest force magnitudes were measured for labial straight archwires at each tooth position. The lateral incisor experienced the largest gingival forces with all archwire forms. The first premolar and first molar experienced labial−lingual crown tipping moments in opposite directions between labial and the two lingual archwire forms.

Conclusions

Biomechanical differences between labial, lingual straight, and lingual mushroom treatment modalities for the correction of curve of Spee misalignments were elucidated. Labial straight archwire exerted the lowest force magnitudes overall. For both lingual archwire forms, the labial−lingual inclination of the first premolar could be highly variable during levelling.
Learning Outcomes, Benefits, and Challenges of International Research Experiences for Students (IRES): An Exploratory Study of an IRES Program in China

Published: October 2024

Despite the increasing number of international programs targeting students’ learning of research and intercultural skills, there has been limited holistic investigation of students’ experiences employing both qualitative and quantitative methods. In this study, we incorporated several measures to explore students’ experiences in an International Research Experiences for Students (IRES) program, which benefited from the existing partnership between Virginia Tech in the U.S. and Shandong University in China. We examined students’ intercultural competence and interdisciplinary research skills and explored students’ stories of their lived experiences across three cohorts, each with five students, who completed the IRES program. Both open-ended survey responses and interview data demonstrate that the experience allowed students to learn skills involving the various tools, methods, and processes needed to conduct experiments and solve interdisciplinary problems. In particular, qualitative data further demonstrated the influence of the program on students’ desire to pursue graduate degrees and navigate the research process. While the behavioral dimension of cultural intelligence did not show a major improvement, student interviews suggested enhanced student abilities in interpersonal interactions, including non-verbal and verbal means for effective communication. We provide explanations for the differences between quantitative and qualitative results. Reflecting on the results, we elaborate on the importance of structural elements necessary for creating international experiences for students and the need to examine students' learning processes using different means of data collection.
Cluster analysis on a suite of upper mantle xenoliths from the Nógrád–Gömör Volcanic Field (Northern Pannonian Basin)
Authors: Patkó Levente , Kuslits Lukács , Czirok Lili , Liptai Nóra
Published: October 2024

The Nógrád–Gömör Volcanic Field is one of the most thoroughly studied upper mantle xenolith-bearing localities in the Carpathian–Pannonian region. Dozens of upper mantle xenoliths collected there have been investigated from various aspects in the past decades. Major element compositions of upper mantle xenoliths available in scientific papers on the Nógrád–Gömör xenoliths were extracted to build a database. This database includes the geochemical composition of the rock-forming minerals (olivine, pyroxenes, spinel) of 112 upper mantle xenoliths. Using the data compiled in this database, we applied the CluStress algorithm to perform cluster analysis. The results led to the division of 2 supergroups (I and II) and 17 groups within them. Supergroup I was split into two subgroups (Supergroup I/a and I/b). The xenoliths of Supergroup I/a and I/b are distinguished by their orthopyroxene/clinopyroxene modal composition ratios (mainly >1.5 and <1, respectively) as well as their olivine Mg-numbers (dominantly >0.89 and <0.89, respectively). Most of the xenoliths (~50% of all classified xenoliths) were sorted into Group 1 within Supergroup I/a, and they appear at almost all xenolith-bearing localities in the Nógrád–Gömör. The Group 1 xenoliths exhibit narrow compositional ranges regarding their major element relationships. Due to their common occurence and spatial distribution, these rocks were considered to represent an ambient lithospheric mantle under­neath the study area. The geochemical characteristics of the other groups allowed their linking to different events described in former scientific works. At least 11 out of the 17 distinguished groups (i.e. ~35% of the classified xenoliths) are strongly related to the Neogene alkali basaltic volcanism. This suggests that the pre-Neogene rootzones of volcanic fields in the Carpathian–Pannonian region were significantly modified by intensive melt-rock reactions between upward migrating basaltic melts and wall rocks, which took place in the last ~10 million years.
Solving the two-machine flow-shop scheduling problem to minimize Makespan with a partial order between operations
Authors: Romanova A.A , Tavchenko V. Yu
Published: October 2024

The paper deals with the two-machine flow shop scheduling problem, which occurs in cross-docking product delivery system. The specificity of the problem is the presence of a partial order between operations, that is, an operation on the second machine can not begin execution until the completion of a certain set of operations on the first machine. We need to find a schedule with the minimum makespan. We propose a polynomial time algorithm with an approximation guarantee. We also find a polynomially solvable case of the problem with unit durations of operations.

Philosophical-hermeneutic reflection of the problem of alienation in education
Authors: Nikolaeva A.B.
Published: October 2024

The aim of the article is to comprehend the problem of alienation in education from a philosophical and hermeneutic standpoint, which is increasing today, during a period of social and mental uncertainty and a change in cultural periods (postmodernity is gradually giving way to metamodernism). Alienation in education often leads to obvious activity problems, a halt in the process of value-world outlook development, and even an existential crisis. On this basis, the article discusses overcoming alienation in education by creating a special conceptual and cognitive space, referring to hermeneutic methods of interpretation, understanding and explanation, to joint philosophical reflection of students and teachers, joint interpretation and comprehension of the material.
Information shelter as a way of self-identification in the modern digital information space
Authors: Vetrov S.A. , Konishevskii D.V.
Published: October 2024

Modernity is characterised by an increase in activities that are carried out remotely and an increase in the number of people involved in symbolic production, i.e. the production of a creative product. Digitalisation encompasses not only production, but also leisure activities. At the same time, in reality, the individual remains alone in the information space. The problem of structuring space and time becomes relevant to solve the problem of self-identification. The author's concept of an information shelter helps to solve the above problem.
Strategic framing as an object of communication studies: origin, problems, prospects
Authors: Kushneruk S.L.
Published: October 2024

The article focuses on the problem of strategic framing in communication studies. The author aims at investigating the possibilities of strategic use of mental-linguistic structures as interpretation schemas activated by discourse agents and processed by audiences. The objective of the author is made observable in the following tasks: to systematize the approaches to frame, proposed by scholars; to discuss the roots of the framing theory that predetermined different vectors of scientific analysis; to discuss problems and prospects of strategic framing research in communicative linguistics. Within the framework of the research, the author have analyzed more than 60 papers written by experts who contributed much to understanding the mechanisms of social reality construction. It is revealed that psychology, sociology, and artificial intelligence are major source domains of the framing theory. It is proved that strategic framing is a very useful paradigm, which is actively employed in analyzing public relations. It is argued that the theory of strategic framing, purported by Goffman's ideas and social constructionism tenets suggested by Berger and Luckman, has evolved into a separate branch of communication studies. Potential applications of the strategic framing theory that can be methodologically used for the development Russian discourse studies and media linguistics are outlined.
Social media as an integral element of modern communication
Authors: Temnikova L.B. , Vandisheva A.V.
Published: October 2024

The authors of the article considered the main problems associated with the activities of people in the information space. In this work, it becomes obvious that the characteristic features of the modern information society are global informatization and computerization, the dominance of the Internet and social networks in the exchange of information. Moreover, it is quite obvious that social networks have become an integral part of modern life, and today it is impossible to imagine communication and the development of a person's creative potential without them. The new type of online interaction has marked a fundamentally different situation, when configurations of group communication have replaced traditional linear communications. In online communication, users, as well as in offline everyday life, devote more time to private, domestic interests and hobbies, rather than socially significant issues. Depending on the conditions of communication, content on social networks can be either written, written-visual or visual. Today, information on social media is increasingly represented using visual images, although initially the Internet was not. According to numerous studies, it became known that the majority of users publish photos without text or shorten it to two sentences.
Communication strategies of the author, text, and reader in contemporary drama
Authors: Kozhina M.A.
Published: October 2024

The article discusses the communication strategies used by contemporary playwrights to include the reader in the action of the play. The author of the article notes that the latest Russian drama originates from the “new drama” (or “new new drama”) movement, whose representatives turned to the aesthetics of shock to influence the audience, showing marginal characters in an ugly, disgusting world. Today, the communication strategies between the author and the reader and the impact on the recipient have changed. The researcher aims to consider how the playwrights who came after the authors of the “new drama” build communication with the reader. The tasks that are solved in the work are to analyze the works of modern drama from the point of view of the structure of the action, the series of events, compositional construction and to find in the plays the possibilities for the strongest connection of the reader to the content of the work. As material, the plays by Anya Agapova (“Shop of unnecessary things”) and Daniil Gursky (“activity: fear and awe vol.1”), presented at the festival of young dramaturgy “Lubimovka” in recent years, are considered. The selected plays are interesting in that the authors use constructions that are atypical for dramaturgy, suggesting new ways of interacting with the reader for a contemporary play. As a result of the study, the author of the article comes to the conclusion that the dramatic action, inscribed in the game structures, allows you to activate the processes of perception, give the reader freedom in interpreting the meaning and make him a fullfledged co-author of the work.
ODP-DASHBOARD: Enhancing Marine Species Conservation in the South Atlantic through Linked Open Data Integration
Authors: Nuñez Gustavo Marcelo , Buckle Carlos , Zárate Marcos
Published: October 2024

This paper presents the development of a Cloud-based dashboard called ODP-DASHBOARD (Ocean Data Platform), to manage information from the Marine Biodiversity domains and Oceanography. In this context, the Linked Open Data (LOD) paradigm has emerged as a set of best practices for connecting, sharing and exposing data and knowledge. A central part of this paradigm are ontologies, which allow the definition of shared vocabularies and conceptual models that help integrate this information. These considerations provide a strong motivation to formulate a system that takes into account geospatial characteristics that can provide answers to questions such as the following: (i) How can we define spatial regions for our studies? (ii) How are species distributed in a given region? (iii) Given a particular georeference, what geographic region does it belong to? (iv) How to relate species occurrences to environmental variables within a specific region?. This system is composedof (i) Architecture; (ii) Conceptual model and (iii) Linked data set for exploitation through a SPARQL endpoint. The evaluation was carried out from two approaches, the first of which consists of validating the dashboard using real data extracted from Marine Biodiversity and Oceanography repositories and then validating the proposed conceptual model using competency questions. The second approach has to do with validation through case studies defined together with researchers from the Scientific and Technological Center (CENPAT-CONICET).
Flexibility in committee size and the effect on collective performance: The unanimity rule
Authors: Ben-Yashar Ruth
Published: October 2024

This paper contributes to the understanding of how flexibility in the number of members in a decision-making committee in a multistage project can enhance the accuracy and efficiency of the decisions taken. While most projects typically employ a fixed number of decision makers, the paper demonstrates the advantages of adjusting the committee size according to the project’s varying complexity at different phases of the project. In particular, we show that allowing for flexibility in the size of a committee increases the likelihood of reaching a correct decision under the unanimity rule. We analyze this issue when the decision maker’s competence is independent of the state of nature and when it is not. The results are compared to those under the simple majority rule.

Published: October 2024

The Tatra Mountains stand out as the wettest and most water-rich region in Poland. Despite this, limited studies addressed this issue, and current knowledge largely relies on data obtained in the mid-20th century, with a substantial lack of current estimates. This study aims to fill this gap by evaluating the contemporary water resources of springs in the Tatra Mountains. The study bases on the most recent hydrological mapping of 1,018 springs. The spring resources were evaluated using parameters such as the number of springs, specific runoff, and crenological index, analysed across different physiographic regions, tectonic units, and altitudinal zones. Our studies showed that the highest number of springs occurs in the Western Tatras (66%) between 1000 and 1400 m a.s.l., especially within the Sub-Tatric unit. Springs with discharges ranging from 0.1–1.0 dm3∙s−1 constitute approximately 70% of all springs but they contribute to only 8.1% of spring water resources. Total spring discharge amounted to 2726 dm3∙s−1 and was higher in the Western Tatras (1982.5 dm3∙s−1 than in the High Tatras (743.5 dm3∙s−1 . The specific runoff amounted to 12.9 dm3∙s−1 m−2 with the highest total runoff at altitudes occupied by the most abundant karst springs (1000–1100 m a.s.l.). The crenological index amounted to 4.8 springs∙km−2 and was higher in the Western Tatras (6.5 springs∙km−2) than in the High Tatras (4.9 springs∙kmup−2) . The analysis revealed that the only five largest karst springs, constituting a mere 0.5% of all springs, account for 65% of spring water resources in the Tatras.
Ecohydrological role of groundwater outflows in the functioning of the ecotone zone in Lake Jaczno, Poland
Authors: Kekatierynczuk-Rudczyk Elżbieta , Puczko Katarzyna
Published: October 2024

The research determined the influence of natural groundwater outflows from the spring peat bog on the water supply and its quality in Lake Jaczno. Lake Jaczno is located in the Suwalski Landscape Park (SLP) in the Podlaskie Voivodeship, north-east Poland. The research was conducted from April 2009 to October 2010 and from September 2022 to September 2023. Water samples were collected from spring areas, shallow groundwater, and from Lake Jaczno. Fieldwork involved measuring flow, temperature, water electrolytic conductivity (EC), dissolved oxygen (DO) concentration, water oxygen saturation (WS), and water reaction (pH). Chemical analyses of water samples were carried out in the laboratory. Findings indicate that groundwater, spring water, and lake water in the SLP maintain high quality, with no significant changes in chemical composition over the past decades. Additionally, the physical water parameters display low temporal variability. The EC in the tested waters oscillates around 500 μS∙cm–1. Both spring and lake waters are well oxygenated (97–100%). Biogenic element concentrations exhibit higher variability, influenced by flora development in areas with natural groundwater outflows. High oxygenation of water contributes to increased concentrations of nitrates. The analysed waters exhibited similarity in the concentration and structure of phosphorus forms. Additionally, sediment chemical parameters at Lake Jaczno suggests a buffering capacity in the transitional zones between water and land. Despite similarities in chemical composition, sediment granulometry suggests low permeability, potentially restricting exchange between groundwater and surface waters. Monitoring springs in these environments is important due to their impact on quantity and quality of water in the analysed areas.
Spatial evaluation rainfall estimation on weather radar using Marshall–Palmer reflectivity–rainfall rate in Banten
Authors: Hartanto  , Humaidi Syahrul , Frida Erna , Ananda Naufal , Sinambela Marzuki
Published: October 2024

Based on data from the National Disaster Management Agency (Ind.: Badan Nasional Penanggulangan Bencana – BNPB), throughout 2022, more than 91% of disaster events were hydrometeorological disasters, with floods at 43% and landslides at 17%. One of the factors for floods and landslides is high rainfall intensity. Automatic rain gauge (ARG) is a rainfall observation instrument that can accurately measure rainfall at observation points. However, it has problems such as communication systems that cause delays in data transmission, low instrument density, and inability to cover a wide spatial area, which can affect the accuracy of rainfall information. Weather radar is a remote sensing instrument that can estimate rainfall spatially so that weather radar observations can reach areas of the region that do not have ARG. However, before being used as rainfall information, estimation rainfall needs to be evaluated or calibrated. Evaluation of rainfall estimation on weather radar to ARG in Banten at a 30– 120 km distance range, shows a coefficient of determination above 0.8. Based on the studies that have been conducted, increase of root mean square error (RMSE) is due to influence of radar observation range and observation distance on ARG. Adjustment of rainfall estimation improves the accuracy of rainfall estimation. Adjusting rainfall estimation can reduce RMSE by 50%.
Release of selected nutrients from polymer-coated fertilisers in the soil environment
Authors: Włodarczyk Małgorzata , Siwek Hanna , Lubkowski Krzysztof , Buchwał Anna
Published: October 2024

The aim of the study was to evaluate the release of NH4-N and PO4-P from polymer-coated fertilisers in the soil environment, and to analyse their impact on pH and conductivity of the soil leachates. In this investigation mineral NPK(S) 6-20-30(7) fertiliser (as a starting material), commercial, controlled-release OsmocoteTM fertiliser (as a reference material) and four polymer-coated fertilisers have been used. Biodegradable polybutylene(succinate-co- dilinoleate), polyethylene(succinate-co-terepftalate) and chitosan have been used as coating materials. The experiments were conducted in the laboratory conditions, in PVC columns filled with air-dry soil. The nutrients release from the investigated materials was explained based on the diffusion mechanism and it was interpreted with the use of the Korsmeyer–Peppas kinetic model. Two mechanisms dominate in the release process of nutrients: the mechanism based on quasi-Fickian diffusion and non-Fickian (anomalous case) mechanism. The largest changes of pH and electrical conductivity (EC) of soil leachates occurred in the initial period of research for all tested fertilisers (pH: 9.5–20.3% – loamy sand (S1) 7.9–20.6% – sandy loam (S2); EC: 438–1667% – S1, 771–1509% – S2). The polymer coating significantly reduces the nutrient release from the fertiliser core. The size of these changes depends on the type and thickness of the polymer layer and the physicochemical properties of the soils.
Small intestinal incarceration caused by external herniation can be diagnosed clinically in cattle, but laparotomy is required to confirm internal incarceration
Authors: Braun Ueli , Gerspach Christian , Bennien Elena , Hilbe Monika , Nuss Karl
Published: October 2024

OBJECTIVE

To describe the clinical, laboratory and ultrasonographic findings, treatment, and outcome of cattle with small intestinal incarceration (SII) through internal and external hernias.

METHODS

The medical records of 85 cattle with SII admitted between January 1, 1987, and December 31, 2019, were retrospectively reviewed. The long-term outcome was determined 2 years after discharge.

RESULTS

85 cattle had herniation of the small intestine through congenital or acquired openings in mesentery or omentum (internal herniation; n = 60) or the abdominal wall (external herniation; 25). The most common findings were little or no feces in the rectum (77 of 85 [90.6%]), reduced or absent intestinal motility (76 of 85 [89.4%]), and hypocalcemia (36 of 44 [81.8%]). Thirteen (15.3%) cattle died or were euthanized without surgery. Of the remaining 72 (84.7%) cattle that underwent surgery, 42 survived the procedure. Overall, 52 of 85 cattle (61.2%; 95% CI, 50% to 72%) did not survive to hospital discharge and 33 (38.8%; 95% CI, 28% to 50%) were discharged alive. Of these, 11 (33.3%; 6 with and 5 without hernias closed completely) were still productive in their respective herds 2 years later.

CONCLUSIONS

The diagnosis of an incarcerated external hernia is usually straightforward, whereas internal SII necessitates laparotomy or postmortem examination for a definitive diagnosis.

CLINICAL RELEVANCE

Internal herniation should be part of the differential diagnosis in cattle with signs of ileus. Immediate surgical treatment is paramount in cattle with SII.

This study aimed to explore the effects of essential nutrients on various aspects of Pacific white shrimp, Litopenaeus vannamei, including growth performance, survival rates, tissue mineralization, digestive enzyme activity, and redox and immune status. Under the brand name Bonza®shrimp, the chelated supplement, containing Zn, Cu, Mn, Mg, Ca, P, Fe, and Se, was manufactured based on the advanced chelate compound technology, registered with the United States Patent (No. US8288587B2). Then the shrimp (weight of 8.55 ± 0.24 g; n = 420) were randomly assigned into six experimental groups (Bonza®shrimp mixed in diet treatments: MT1: 250; MT2: 500; MT3:1000 mg kg-1, and sprayed on diet treatments: ST1: 250; ST2: 500; ST3:1000 mg kg-1) and one control treatment (CT). At the end of the feeding trial (60 days), the shrimp fed with diets containing Bonza®shrimp (especially MT3 treatment) showed a significant enhancement in growth performance, i.e., weight gain, survival, and feed conversion ratio, compared to the CT treatment (P < 0.05). Moreover, the supplementation of Bonza®shrimp at the highest dose markedly increased the levels of the applied minerals and ash in the muscle tissue and whole-body. Likewise, the administration of the organic supplement markedly raised the levels of total protein, glucose, cholesterol, and triglyceride particularly at the highest dosage, i.e., the MT3 treatment. Besides, the inclusion of this supplement considerably increased the activities of amylase, lipase, phenoloxidase, lysozyme, superoxide dismutase, alkaline phosphatase, and acid phosphatase enzymes (P < 0.05). Also, the total haemocyte count in shrimp fed with the supplement (MT2 and MT3) was significantly higher than the other treatments. Therefore, the supplementation of Bonza®shrimp could not only improve the growth performance, macro- and microelement levels in the body, and digestive enzyme activities but also enhance the redox and immune status. The outcomes recommend that the supplement could adjust the energy allocation among various traits probably through optimizing the metabolism. According to the fitted linear regressions, furthermore, the method in which this organic supplement (at the level of 1000 mg kg-1) was premixed with the diet can be more effective than the top-dressing method. Together, this study introduces the mineral supplement, synthesized using a patented procedure, as a metabolism optimizer to enhance growth performance, meat quality, digestive system, and immunity of L. vannamei.

Authors: Konefał Marek , Błażejczyk Krzysztof , Chmura Jan , Żmijewski Piotr , Różański Paweł , Szmigiel Błażej , Chmura Paweł
Published: October 2024

Study aim: This study aimed (i) to describe psychomotor parameters for different temperature and humidity conditions, and (ii) to verify whether conditions at the borderline between some and great thermal discomfort on the humidex scale affect psycho-motor parameters in soccer players.

Material and methods: Twenty-four male soccer players aged 21.02 ± 3.22 years from a Polish 4th league club performed a graded treadmill running exercise test. Directly before the test and during the break after each load, blood was collected to determine lactate concentration ([LA]) and serotonin concentration (SER). The heart rate (HR), pulmonary ventilation (Ve) and oxygen up-take (VO2) were recorded and the psychomotor test was performed. Measurements were carried out: (1) at rest, (2) at the lactate threshold (T[LA]), (3) at the threshold of psychomotor fatigue (TPF), and (4) at maximum intensity. Percentage differences between maximum intensity (100%) and the values of the tested parameters recorded at the T[LA] and TPF were also calculated. The tests were conducted in a climatic chamber at an ambient temperature of 28.5°C, with a relative air humidity of 58.7%.

Results: It was confirmed that the TPF, which reflects the highest efficiency of the central nervous system, occurs at a higher running speed than the T[LA]. For practical application, it was found that at the HSL, the TPF occurs at: 84% of maximum running speed, 52% of maximum [LA] concentration, 93% SERmax, 91% HRmax, 73% VEmax, 84% VO2max.

Conclusion: Understanding the psychomotor and physiological responses of soccer players at the borderline between some and great thermal discomfort (on the humidex scale) can support coaches in optimizing training sessions to prepare players for playing in more challenging climatic conditions.
Using birds of prey to manage pest bird flocks under lethal and non-lethal conditions – A review
Authors: Wallis Robert , Coles Graeme
Published: October 2024

Raptors have been successfully used to disperse and often control flocks of pest birds. However, the question that has not been resolved is, “If the raptor kills a small number of the target flock, does this improve the efficiency of control?” This mini-review examines the few research reports that have been published that can shed light on this question.
Raptor rehabilitation in Florida: Admission reasons, care duration, and release rates during the last fifteen years
Authors: Pahl Aaron
Published: October 2024

Wildlife rehabilitators treat thousands of raptors yearly, providing an opportunity to better understand species’ biology, the changing environment, and the dangers raptors encounter in the wild. However, that data is siloed within individual facilities, making it challenging to understand the wider impact of rehabilitation and the dangers raptors face. Data were collected from 50 facilities across the state of Florida, United States of America, from 2009 to early 2023, representing 54,574 patients of 39 species. Patient intake at these facilities doubled between 2010 and 2020 over a relatively stable number of facilities (average = 31.5/year) with an average release rate of 36.6% (range 31.7 – 41.5%). Release rates varied significantly from 21% to 57% between species with over 100 recorded patients.

Comparing release rates with the “cause for admission” provided a more nuanced understanding of what was affecting raptor patients and their release rates. Trauma was the most common cause of admission (40.2%) and has been relatively consistent year over year. For those patients with more specific identification attributes, 65% were male, 50% were adults, and patients spent an average of 16.6 days in care. The data provided in this study has the potential to make fundamental changes to raptor rehabilitation policies and encourage more collaboration between rehabilitators and researchers for the betterment of the patients in care.

Authors: Araújo Nícolas Matheus da Fonseca Tinoco de Souza , Santos Paula Rose de Araújo , Abrahão Raphael
Published: October 2024

Objective: This study investigates how the researchers approached the theme the climate change impacts on photovoltaic production (PVP) from the perspective of simulations using climate models.
 
Methodology: A comprehensive literature review was conducted to establish correlations between future PV production and climate change susceptibility on regional and global scales. Keywords related to the theme were used in the Web of Science database. Inclusion criteria selected only complete, free, English scientific articles related to the research theme, published between 1965 and 2023.
 
Results and analysis: As a result, it generated a sample consisted of 58 articles on the impact of climate change on photovoltaic production, with 14 included in the final quantitative synthesis. A wide range of results was presented, stemming from both climate change models and models assessing the influence of weather-related factors on PV production. Patterns in the impacts of climate change on photovoltaic production were observed, and the main climate models used to estimate PVP were recognized, grouped, and discussed. Key databases, commonly used simulation periods, and equations linking meteorological variables to PVP were identified and examined.
 
Conclusion: Numerous publications have emerged on the impacts of climate change on PVP, focusing on empirical equations that relate meteorological variables, cell temperature, and cell efficiency. Most studies adopted a forecast period until the end of the 21st century. The majority of the studies focused on Europe and Asia, with little research on impacts of climate changes on PVP in South and Central America.
Determinant Football Elements for Euro16 Match Results
Authors: Rocha-Lima Eric Matheus , Wallan Tertuliano Ivan , Norberto Fischer Carlos
Published: October 2024

Purpose: The current article aimed to verify patterns that could explain match results of the Euro Cup 2016, using as references the following match performance indicators: finishing, ball possession, passing, crosses and defensive actions.
Methodology/approach: The necessary information about the matches was collected from the Dailymail’s website. The Weka (Waikato Environment for Knowledge Analysis) program was adopted to help in the analyses of these data.
Originality/Relevance: Football matches components have been analysed in order to understand the behavior of the teams in the competitive scenario of this sport. 
Key findings: The results show that the more accurate shots a national squad takes in their games, the more chances they got to win, instead of using a game plan based on crossing movements. Ball possession, on its turn, can be a good indicator or a bad one to win matches, when associated to a high number of crosses. Moreover, the alternative of long passes seems to be relevant only when the opponent makes more shots from outside the area or get more blocked shots. Complementarily, defensive actions focused on successful tackles and more interceptions appear as a positive aspect for getting the triumph, considering only the total number of tackles. The accuracy of kicks and defensive actions were relevant to the success of the teams in the competition, suggesting that the improvement of actions related to these two indicators should help national teams to improve their own strengths, in order to maximize their chances of winning matches.
Theoretical/methodological contributions: Collecting a large volume of football data from a website and using the Weka program have helped not only to speed up and facilitate the analyses but also should have been important in order not to lose any relation that could be relevant inside the studied scenario.
Endoscopic transpapillary interventions for cholelithiasis complications
Authors: Tulyaganov D. B. , Atadjanov Sh. K. , Aliev B. A. , Magdiev Sh. A.
Published: October 2024

The article provides a review of modern literature on the problem of treatment of cholelithiasis complications and endoscopic transpapillary interventions. The pathogenetic mechanisms of these complications were analyzed. Studies on the impact of the timing of laparoscopic cholecystectomy after endoscopic transpapillary interventions show that the risk of recurrent biliary complications increases significantly in patients when cholecystectomy was delayed, while early performance of this operation after endoscopic transpapillary interventions reduces the risk of developing these complications
La inspección de servicios en las universidades públicas de Andalucía
Authors: García Menéndez Javier
Published: October 2024

Objetivos: analizar el grado de implementación del modelo de inspección diseñado por la Ley Orgánica del Sistema Universitario (LOSU) en el sistema universitario público de Andalucía. Metodología: se realiza un estudio de caso comparado, en el que se aplica un marco común de evaluación focalizado en torno a dos variables, la estructura de personal de los servicios de inspección y el grado de desarrollo de las funciones inspectoras. Resultados: se evidencia un predominio de las estructuras de personal configuradas según la normativa anterior a la LOSU, aunque casi todas las universidades alcanzan la suficiencia en cuanto a las competencias que despliegan sus inspecciones, dentro del marco establecido. Conclusiones: desde el punto de vista funcional, con una sola excepción, las universidades se encuentran en condiciones de poner en funcionamiento la nueva unidad de inspección; por contra, en el plano organizativo aún está pendiente una reordenación de los recursos humanos que coadyuve a profesionalizar la función inspectora.
Los resultados evidencian un predominio de las estructuras de personal configuradas según la normativa anterior a la LOSU, con direcciones de la inspección desempeñadas mayoritariamente por profesorado. En cuanto a las competencias que despliegan los servicios de inspección, las universidades se sitúan en estadios desiguales, aunque casi todas alcanzan la suficiencia dentro del marco establecido.
Desde el punto de vista funcional se concluye que, con una sola excepción, las universidades se encuentran en condiciones de implementar la nueva unidad de inspección. Por contra, en el plano organizativo aún está pendiente una reordenación de los recursos humanos que coadyuve a profesionalizar la función inspectora. Para ello resulta imprescindible una firme apuesta política desde los rectorados, que deberá considerar el impacto de esta innovación dentro de las estructuras de poder tradicionales.

Authors: Agozzino Alisa , O'Hallarn Brendan , Stensland Peyton , Strode James
Published: October 2024

This paper introduces Sport Social Hub, a collaborative, multi-institutional social media exchange inspired by the Commission on Public Relations Education's (CPRE) emphasis on key knowledge, skills, and abilities (KSAs) in public relations education. Sport Social Hub engaged students from four universities in topical, sports-themed assignments. These assignments involved creating memes, analyzing historical and contemporary sports photographs, profiling industry professionals with infographics, and developing engagement contests. The paper outlines how Sport Social Hub addresses CPRE's recommended KSAs within social media, collaboration, and creative thinking. Utilizing social media platforms as pedagogical tools, Sport Social Hub aimed to enhance students' social media competencies, promote collaboration across institutions, and develop relationships in a virtual environment. The paper provides an overview of the assignments, each assignment’s objectives, and the connection to CPRE's Fast Forward report. Assessment and feedback mechanisms are explored, highlighting the positive impact on students' social media competencies, networking with industry professionals, and the sense of community fostered through online engagement. While acknowledging the limitations and challenges, the authors propose Sport Social Hub as a model for educators seeking to integrate collaborative, hands-on, and crowdsourced approaches in their pedagogy to prepare students for the evolving landscape of communication careers.
