Bioavailability of potentially toxic elements in selected Cu-deposits of Europe
(Nitrianske Pravno Ústav geotechniky Slovenskej akadémie vied : Košice, 2024) Andráš, Peter; Midula, Pavol; Ševčíková, Janka; Šuránek, Matej; Matos João Manuel, Xavier; Janštová, Jana; Buccheri, Giuseppe; Tomaškin, Ján; Drímal, Marek
Bioavailability of potentially toxic elements from four dump-field material at several abandoned European Cu-deposits: Špania Dolina (Slovakia), Caporciano and Libiola (Italy) and São Domingos (Portugal) was studied. The three steps sequential analyse study show some relation among geological setting and mineralogical composition of ores vs. bioavailability of metals. The best bioavailable metals at first three mentioned deposits are Cu and Cd (in one case, atr São Domingos As and Co). The results confirmed that the geological setting substantially influence the order of the bioavailability.

Out-of-school learning and students' motivation
(Uniwersytet Pedagogiczny im. Komisji Edukacji Narodowej w Krakowie, 2024) Skoršepa, Marek; Kmeťová, Jarmila; Şen Ahmet, İlhan
Out-of-school learning has been reviewed (Şen, A. İ. et al., 2021) as a promising way of teaching Science actively due to its ability to provide students with firsthand experience. Another driving force of education is motivation. It can stimulate a considerable part of students’ abilities and help lead to achieving desired educational aims. In this contribution, we provide partial results of evaluating students’ motivational orientation concerning learning in out-of-school settings. The background for the study is an Erasmus+ project, where partners from four countries (Turkey, Slovakia, Czechia and Germany) aimed to develop an out-of-school learning curriculum for teacher training study programmes. Herein, we present the Slovak motivation data gained while performing and evaluating two specific activities proposed for the following out-of-school setting: (i) education in the pharmacy and (ii) education in the distillery (Skoršepa et al., 2022). The research includes data from 152 grammar school students (average age M = 15.76). The renowned psychological tools MSLQ and IMI were used to measure students’ motivation.

Is there a difference in the education of generations across time?
(IOP Publishing : Bristol, 2024) Spodniaková Pfefferová, Miriam; Hruška, Martin; Raganová, Janka; Holec, Stanislav
An interesting reading tends to be a summary of the dominant characteristics of each generation, which can be found in scientific and vocational publications as well as in media with popularization texts. Very often, we also identify among them our own characteristics and qualities, or those of our peers, children, and possibly other descendants. It is natural that the development of science and technology has a significant role in shaping the personality profile of the members of each generation during the historical development of society (for example, from the "lost" generation to the "alpha" generation). This factor influences the content, methodological and didactic aspects of the teaching process, i.e. what and how to teach. The authors of the paper have worked on several aspects of the preparation of teaching materials and their use in school physics, often with overlap with other science subjects. One of these aspects is, for example, the need to influence the emotional side of the student in learning processes, which is an important prerequisite for more permanent "inscriptions" of information in the student's memory. For this process to work, knowledge of the dominant characteristics of the target group of students and the environment in which they grow up is essential.
Kvalitatívna analýza riešenia grafových úloh s ChatGPT
(Technická univerzita v Liberci, 2024) Škrinárová, Jarmila; Hamada, Adrián; Voštinár, Patrik; Vagač, Michal
The ChatGPT tool has become one of the most popular applications of artificial intelligence, which is used to obtain answers to questions, but especially to solve tasks from various fields. We have encountered opinions that some answers of the ChatGPT are accurate, and others are wrong, or that students will not be able to solve tasks due to the availability of the ChatGPT tool, which will lead to a degradation of the student's thinking. We asked ourselves a research question: "Does the solution of graph tasks with ChatGPT contribute to the degradation of the student's thinking of the 1st and 2nd year of gymnasiums". We focused on solving graph tasks for the "Junior" category of the iBobor competition. These tasks are: "Pedigree" from 2012/13 and " Photos on the social network' from 2015/16. We gradually presented the solution to both tasks. Each task was solved by several students, in Informatics methodology subject, who worked together and thus 5 experiments were created with the aim of answering the questions specified for the qualitative analysis and answering the research question. We specified questions for qualitative analysis: Do the students understand the assignment? Can the assignment as formulated for the student be used as an assignment for ChatGPT? How should we phrase questions for ChatGPT to get the expected type of response? Is ChatGPT's answer to our questions always, correct? Does entering a task for ChatGPT in Slovak and English language lead to the same answers? Based on the results of the experiments, we were able to gradually formulate the answers: It is essential that students clearly understand the assignment. We perceive the importance of the teacher in the analysis of the task, specification of details and communication with the students. We have shown that it is necessary to divide a complex assignment into parts. Skill in asking questions needs to be acquired. ChatGPT is a new and dynamically changing tool. Therefore, it is necessary to work with this tool and perceive the "learning" feature of this tool. The ChatGPT response is not always correct. The necessity of knowing how to solve tasks correctly was confirmed for us. This is necessary so that we can judge whether ChatGPT responded correctly or not. Entering a task for ChatGPT in Slovak and English can lead to different answers. We interpret this as the student's ability to better formulate an assignment in English than a "machine" translation from the Slovak language does. Based on the qualitative analysis, we can conclude that the teacher and the student, when solving tasks with ChatGPT, need: understand the task assignment in detail, be able to formulate the tasks more consistently for ChatGPT and possibly reformulate or supplement this assignment and be able to correctly solve graph tasks so that we can verify the correctness of the ChatGPT solution. It follows from the above that we must reject the hypothesis in the research question. We have shown that student's thinking does not degrade. We have shown that the consistent solution of graph tasks with ChatGPT contributes to the development of the thinking of teachers and pupils.
Updated checklist of the Chironomidae Newman, 1834 (Diptera) of Czechia and Slovakia
(Prešovská univerzita v Prešove, 2025) Bitušík, Peter; Chamutiová, Tímea; Syrovátka, Vít; Brabec, Karel; Hamerlík, Ladislav
This contribution updates the chironomid fauna of Czechia and Slovakia (Bitušík & Brabec 2009). A total of 501 species are known currently from both countries. The checklist includes 374 species from Czechia and 406 species from Slovakia. Considering the historical division of Czechia into regions, 292 species have been recorded in Bohemia and 259 in Moravia. References are included only for records published since 2009, when the last checklist was compiled. Despite significant progress in recent decades, the overall understanding of the Chironomidae family in both countries can be considered moderately good but still requires further study.
Subfossil Chironomids Reveal Past Hydrologic Shift in Lake Lala Mare, Eastern Carpathians
(Kocaeli University : Izmit, 2025) Kizilkaya, Selen; Hamerlík, Ladislav; Slobodníková, Veronika; Kubovčík, Vladimír; Bitušík, Peter
Lala Mare is a high-altitude glacial lake (1800 m a.s.l.) located in the Rodna Mountains of the Eastern Carpathians, Romania. In the present study, subfossil chironomids were analysed from a 20 cm sediment sequence to reconstruct past ecological and environmental conditions. A total of 1863 head capsules, representing 26 taxa, were identified, with overall low taxonomic richness. The assemblages were mainly dominated by Tanytarsus lugens-type and Procladius sp. Hierarchical classification analysis revealed two distinct zones: The lower zone was characterized by high abundances of Tanytarsus lugens-type, whereas in the upper zone Procladius sp. became dominant, by a decline in overall diversity, suggesting enhanced productivity. Cold-adapted taxa associated with flowing water, including Diamesa, Eukiefferiella, Tvetenia, and Pseudodiamesa branickii-type, were frequent in the 1stZone, reflecting a cold inflow. In contrast, rheophilic taxa disappeared in the second zone, reflecting a shift water inflow and hydrological changes.
Effect of grain direction on particle size distribution during sanding of spruce, beech and oak wood
(University of Warsaw, 2025) Kučerka, Martin; Očkajová, Alena
This paper focusses on the impact of the direction orientation of the sanding of selected wood types on the particle size distribution. In the experiment, a hand-held GBS 100 AE belt sander was used, with particles obtained through two sanding models: at angles of 0 ° and 90 ° with respect to the wood structure. The study examined the effects of cutting orientation on the particle size distribution in beech, oak and spruce wood sawdust. Statistical analysis was used to characterise the particle size distribution, and a combination of orientations was compared for each type of wood. Statistical analysis revealed significant differences in the particle size distribution between the two cutting orientations, with p-values of 0.018 and 0.0002 for beech and spruce, respectively. On the contrary, oak did not show minimal statistically significant differences between orientations (p = 0.912). The results highlight the crucial role of the wood microstructure in determining the effect of cutting orientation on particle morphology. Specifically, spruce showed the highest sensitivity to orientation changes, while oak remained relatively stable in different cutting directions.
Energetický potenciál a zásoby uhlíka horských lúk
(Ústav ekológie lesa SAV : Nitra, 2025) Kizeková, Miriam; Britaňák, Norbert; Čunderlík, Jozef; Hanzes, Ľubomír; Pollák, Štefan; Vargová, Vladimíra; Jančová, Ľubica; Kanianska, Radoslava
Mountain meadows are an important carbon pool and can also act as a source of bioenergy. The study focused on 4 grassland types (Lowland hay meadows, Mountain hay meadows, Wet grassland of sub-montane zones and Oversown grasslands) in 5 mountain ranges (Great Fatra Mts., Low Tatra Mts., Slovak Paradise Mts., Čergov Mts., Slánské Hills Mts.) of the Western Carpathians in Slovakia. The results showed that the total carbon stock of the mountain meadows equal to 2.120 x 103 tons. The calculated biomethane production ranged from 6,606 GJ in the Slovak Paradise Mts., to 122,888 GJ in the Low Tatra Mts., which had the largest area of grassland habitats. The theoretical energetic potential exceeded 1,139 x 103 GJ.
Improvise. Adapt. Overcome - Baltic Sea Bacteria and Their Polymer Degrading Ability
(Universidade NOVA de Lisboa, 2025) Guziurová, Pavlína; Krempaská, Vladimíra; Sedláček, Petr; Sedlár, Karel; Obruča, Stanislav
As plastics production and consumption today continue to contribute to petrochemical plastic pollution, greener packaging alternatives such as biopolymers and biobased compostable materials are becoming a major focus of research. However, these materials can also pose environmental problems in areas lacking the appropriate degradation conditions. Despite global recycling efforts, plastics frequently end up in landfills and in natural environments such as seas and oceans. Several studies have reported significant microplastic pollution in the Baltic Sea; therefore, the diversity of microorganisms present in these waters may indicate the existence of enzymatic systems capable of degrading polymeric packaging materials. In this study, several tests were conducted to evaluate the degradation capabilities of bacteria isolated from the Baltic Sea on different types and forms of biobased polymers. The formation of halozones was observed and confirmed using agar plate assays with emulsified polymers – poly(3-hydroxybutyrate), poly(butylene succinate) and poly(lactic acid). Selected polymers in granule or film form (prepared via hot pressing or solvent casting methods) were exposed to the bacterial consortium, and material property changes were monitored. Major structural changes were observed using scanning electron microscopy (SEM), while physicochemical property changes were analyzed using differential scanning calorimetry (DSC) and gel permeation chromatography (GPC-SEC/MALS). Additionally, biochemical activity was assessed by measuring biological oxygen demand (BOD) and the optical density (OD) of microbial cultures. Microbial consortium was separated and analysed on MALDI-TOF and sequenced. The results indicate that certain bacteria exhibit potential to for the biodegradation of various polymers. Further research will examine these microorganisms in more detail in future studies.
