Variability of grassland soils’ properties in comparison to soils of other ecosystems
No full textIn: Agronomy. - Basel : Multidisciplinary Digital Publishing Institute, 2025. ISSN 2073-4395. Vol. 15, no. 3 (2025), pp. 1-18.The variety of natural conditions and land use patterns determine high variability of soil properties. This study focused on the analysis of chemical, physical, and biological properties of grassland (GL) soils (situated on slopes—GLS, and on alluvial plains—GLP) in comparison with soils of other ecosystems (arable land, forest land, riparian zone) in Central Slovakia. We applied an indicator’s method combined with models of these properties. The studies showed a large variability, more pronounced in GLS than in GLP. GLP soils were characterized by the highest number, biomass, and diversity of earthworms among all ecosystems. GL soils, in addition to FL soils, also have a relatively high capacity for water retention and C and N storage. However, we found an unfavorable state in available phosphorus, with GLS showing the lowest levels among compared ecosystems.Národné poľnohospodárske a potravinárske centrum 19R01-18-P01-00001 Komponent 19 v Pláne obnovy - REPower E
Integration instead of ghettoisation : integrating refugees with the local communities
No full textIn: Humanitarian aid and empowerment of Ukrainian refugees : the case of Visegrad Group countries: Czechia, Hungary, Poland, and Slovakia. 1. vyd. Abingdon : Routledge, 2025. ISBN 978-1-032-78599-8. Pp. 145-161.Integration, which refers to migration, is a process in which differences between migrants and the rest of society are eliminated to a certain extent. This process is by no means one-way. On the contrary, it is multidimensional and includes all actors. All local actors can be involved in community protection – refugees, local and state institutions, non-profit and community organisations, and volunteers. Their common goal is to ensure respect for human and refugee rights and refugees’ access to information and services, significantly strengthening their self-sufficiency and independence. The involvement of Ukrainian people already living in the countries is crucial for the integration process. For many people from Ukraine, social networks play a crucial role in getting and keeping in touch with others.
The chapter analyses the integration of Ukrainian refugees with local communities, preventing their closure in their milieu and encouraging their participation in the life of local communities. It explores the involvement of local organisations and pre-war migrants in pro-integration and support initiatives. It also focuses on initiatives based on community work as a model for integrating Ukrainian refugees in V4 countries.Visegrad Grants 22230242 Humanitarian aid and the empowerment of Ukrainians coming to the V4 countries - good practice
Internation conference InterRehab : collection of abstracts
No full textThe topics presented in this year’s proceedings reflect the dynamic development of rehabilitation in both theory and clinical practice. As we navigate the post-pandemic landscape, face the growing burden of non-communicable diseases, and work to modernize healthcare systems, one thing remains clear: rehabilitation is no longer an auxiliary or optional service - it is a central component of patient-centered care. From prevention and early intervention to long-term management and reintegration, the scope of rehabilitation is expanding, and so must our thinking
Teacher characteristics influencing plant biology education: age, perception, and practical engagement
No full textIn: Theoretical and Experimental Plant Physiology. Cham : Springer Nature Switzerland AG, 2025. ISSN 2197-0025. Vol. 37, no. 1 (2025), pp. 1-14.Plants are less attractive for students compared to other areas of biology, and teachers may improve this negative scenario. We aimed to investigate the influence of several characteristics of the teacher (e.g. gender, age or technical equipment) on (i) the activity of teaching plant biology, (ii) a number of physiological experiments used in teaching and, (iii) deficiencies in the knowledge of students in plant biology. For this purpose, data were extracted from previous more complex survey and analyzed by General Linear Model. The age, the teachers’ perception of the students’ knowledge and the teachers’ awareness of the importance of the aids significantly correlated with the teachers’ activity in education. Similarly, three teachers’ characteristics (age, school’s equipment and awareness of the importance of the aids) correlated with the number of implemented physiological experiments. In addition, two teachers’ characteristics (age and perception of the students’ knowledge) significantly correlated with the numberof identified gaps in students’ knowledge. In particular, we found that 51-yr-old (or above) teachers use more practical activities and physiological experiments, which may be the reason why they identified fewer gaps in students’ knowledge. Therefore, these more active teachers should be replaced by young teachers of the same quality after their retirement to keep the quality of education
Evaluating the impact of bee bread extract on transcriptional profiles in primary rat osteoblasts
No full textIn: Animal Biotechnology 2025 : winter school : programme and abstracts / rec. Ján Rafay, Sale Dragin. 1. vyd. Nitra : Slovak University of Agriculture, 2025. ISBN 978-80-552-2829-7. Pp. 72-72.Bee Bread (BB) is a fermented natural product rich in bioactive compounds with antioxidant and antimicrobial properties. Research in a rat model showed its potential to enhance diabetic bone structure, suggesting benefits for bone disorders. The aim of this in vitro study was to analyse the effects of BB extract on gene expression in osteoblasts. BB extract was prepared via methanol extraction, filtration, and evaporation, then dissolved in cell culture medium. It was applied to rat osteoblasts at 10, 100, and 200 μg/ml, with untreated medium as a control. After 72 hours, mRNA was extracted, cDNA synthesized, and the expression of 15 target genes (RUNX2, BMP2, BMP7, TGFB1, TGFBR1, BGLAP, ALPL, SPP1, VDR, COL1A1, IBSP, CDH11, VEGFA, TNFSF11, TNFRSF11B) analyzed using real-time PCR, with five reference genes (TBP, HPRT1, PGK1, B2M, LDHA). BB extract upregulated RUNX2, BMP7, TGFBR1, and ALPL in all groups. Dose-dependent effects included increased TGFB1, BMP2, and VDR in BB10; CDH11 in BB10 and BB100; TNFRSF11B in BB100 and BB200; and BGLAP and VEGFA in BB200. SPP1 was downregulated in BB10 and BB100, while TNFSF11, COL1A1, and IBSP remained unchanged. These findings indicate BB extract promotes osteoblast differentiation, bone mineralization, and osteogenesis while inhibiting bone resorption, demonstrating its potential for bone health and therapy.KEGA 012UKF-4/2023 Implementácia inovácií do edukačného procesu predmetov všeobecná a špeciálna histológia živočíchov s orientáciou na prax

The impact of abiotic environmental stressors on fluorescence and chlorophyll content in Glycine max (L.) Merrill
No full textIn: Agronomy. Basel : Multidisciplinary Digital Publishing Institute, 2025. ISSN 2073-4395. Vol. 15, no. 2 (2025), pp. 1-18.In this study, we present the results of the impact of abiotic environmental (chemical) stressors in the soil environment (salinity, acidification, inorganic elements from industry-red mud waste containing Al) on the content and fluorescence of chlorophyll in the assimilating tissues of Glycine max (L.) Merrill, cv. ES Mentor. Under controlled conditions of a pot experiment during the 2023 growing season, we applied graded doses of these stressors (salinity-doses of 20, 30, and 60 g NaCl per 2 dm3 of water used for plant irrigation; acidity-pH 6, pH 5, and pH 4; red mud-200 g, 400 g, and 600 g per pot) and assessed their impact on the effective and maximum quantum yield of photosystem II (PSII), yield Y(II), or the ratio of variable to maximum fluorescence-the Fv/Fm test. These tests are used to detect plant stress. The Y(II) test yielded values in the range of 0.627-0.800. Significant differences (variance analysis, 95% Least Significant Difference-LSD, post hoc test of analysis of variance-ANOVA) in reducing PSII chlorophyll fluorescence (Y(II)) were found between the medium and high doses of all three stressors compared to the control, indicating plant stress response. The Fv/Fm test yielded values between 0.668 and 0.805 and similarly detected stress responses in plants to all medium and high doses of stressors. The evaluated cultivar showed tolerance to moderately increased salt (NaCl) content and red mud levels. This was also confirmed by the chlorophyll content expressed as the Chlorophyll Content Index (CCI). The highest (significantly confirmed) chlorophyll content was found in the control variant and the variants with lower salt content and a soil pH of 6, with values of 35.633-37.467 CCI, compared to variants with higher red mud content (15.533-18.133 CCI) and higher soil acidity with pH 4 (22.833 CCI). Based on the results obtained, we conclude that the ES Mentor cultivar is tolerant to lower doses of the assessed stressors and can be cultivated in agricultural practice. However, medium to high doses of stressors trigger a strong stress response in plants and, therefore, we do not recommend cultivating this variety in contaminated environments.VEGA 1/0220/23 Biodostupnosť potenciálne toxických prvkov na opustených Cu-ložiskách

Performance portrait method: Robust design of predictive integral controller
No full textIn: Biomimetics. Basel : Multidisciplinary Digital Publishing Institute, 2025. ISSN 2313-7673. Vol. 10, no. 2 (2025), pp. 1-30.The performance portrait method (PPM) can be characterized as a systematized digitalized version of the trial and error method—probably the most popular and very often used method of engineering work. Its digitization required the expansion of performance measures used to evaluate the step responses of dynamic systems. Based on process modeling, PPM also contributed to the classification of models describing linear and non-linear dynamic processes so that they approximate their dynamics using the smallest possible number of numerical parameters. From most bio-inspired procedures of artificial intelligence and optimization used for the design of automatic controllers, PPM is distinguished by the possibility of repeated application of once generated performance portraits (PPs). These represent information about the process obtained by evaluating the performance of setpoint and disturbance step responses for all relevant values of the determining loop parameters organized into a grid. It can be supported by the implementation of parallel calculations with optimized decomposition in the high-performance computing (HPC) cloud. The wide applicability of PPM ranges from verification of analytically calculated optimal settings achieved by various approaches to controller design, to the analysis as well as optimal and robust setting of controllers for processes where other known control design methods fail. One such situation is illustrated by an example of predictive integrating (PrI) controller design for processes with a dominant time-delayed sensor dynamics, representing a counterpart of proportional-integrating (PI) controllers, the most frequently used solutions in practice. PrI controllers can be considered as a generalization of the disturbance–response feedback—the oldest known method for the design of dead-time compensators by Reswick. In applications with dominant dead-time and loop time constants located in the feedback (sensors), as those, e.g., met in magnetoencephalography (MEG), it makes it possible to significantly improve the control performance. PPM shows that, despite the absence of effective analytical control design methods for such situations, it is possible to obtain high-quality optimal solutions for processes that require working with uncertain models specified by interval parameters, while achieving invariance to changes in uncertain parameters.VEGA 1/0821/25 Zvýšenie výkonnosti a robustnosti pokročilých mechatronických systémov návrhom zovšeobecneného PID riadenia s využitím derivácií vyšších rádov

No full textIn: Health, sport, rehabilitation. Charkov : H.S. Skovoroda Kharkiv National Pedagogical University, 2025. ISSN 2520-2677. Vol. 11, no. 1 (2025), pp. 6-17.Background and Purpose
Correct posture during the school years is important in children's health, performance (academic) in schools, and well-being. Postural habits (incorrect) in children may lead to significant musculoskeletal disorders; in particular, low back pain and chronic ailments (other); therefore, aims of study was by experiment to validate the influence of six-week postural intervention program aimed at improving the posture in 10-year-old male students in Physical and Sports Education.
Material and methods
Six-week postural intervention program was carried out 6 weeks (May 6 - June 14, 2024), 2 x/ week/ 10 minutes (Tue/ Thu). Six-week postural intervention program was aimed at improving the posture of 20 10-year-old male students: (i) Experimental group (12 (n), 60%; age 10.20 ± 0.40 years, weight 36.20 ± 2.80 kg, height 138.40 ± 2.80 cm); (ii) Control group (8 (n), 40%; 10.20 ± 0.20 years, weight 36.80 ± 2.40 kg, height 136. 20 ± 4.80 cm). Standardized measure in evaluating the posture (utilizing Klein and Thomas's method, as refined by Mayer) was carried out before (Week 1; May 5, 2024) and after (Week 6; June 14, 2024) the six-week postural intervention program. 6-week postural intervention program and its influence was evaluated using the Wilcoxon Rank-Sum Test, Wilcoxon Signed-Rank Test, and Pearson's r.
Results
Significant differences (p ˂ 0.05, 0.01) between 20 10-year-old male students; in particular, experimental group (12, 60%) and control group (8, 40%) was in 4 out of 5 segments of posture (body) in post-test (p ˂ 0.05, 0.01); in particular, head and neck (Z = -2.20, p ˂ 0.05, r = -0.50), abdomen and pelvis (Z = -2.76, p ˂ 0.01, r = -0.62), curvature of spine (Z = -3.20, p ˂ 0.01 , r = -0 .72), shoulders and scapulas (Z = -3.12, p ˂ 0.01, r = -0.70). Insignificant difference (p ˃ 0.05) between 20 10-year-old male students was in shape of chest (Z = -0.56, p ˃ 0.05, r = -0.12; post-test).
Conclusions
Six-week postural program (intervention) improved the posture of experimental group (12, 60%), demonstrating the improvements in 4 out of 5 segments of posture. Postural (target) exercises may reduce the risk factors of musculoskeletal disorders and promote better posture in children in critical developmental years. No significant difference (p ˃ 0.05) between 20 10-year-old male students was in shape of chest, indicating that certain postural features may require different and/or prolonged interventions
