1571. Moč uma in telesa : telo kot politični prostor v desetletju po 1. svetovni vojni na SlovenskemPavlina Bobič, 2024, original scientific article Abstract: Prispevek tematizira ideale in perspektive telesnosti v obdobju pred in po prvi svetovni vojni in jih postavlja v okvir sočasnih poskusov celovite povojne obnove življenj. Na kakšne načine se je princip telesnosti spreminjal v politično krajino, kjer so se spopadle različne ideologije in obenem razkrile svoje poglede na duhovno in telesno moč ter sposobnost (moralne) regeneracije?Tradicionalna ikonografija je črpala iz bogate duhovne in sekularne dediščine ter se klesala ob predstavah o vzgojnih prijemih in pasteh dobe. Dileme so se znotraj sokolskih in orlovskih telesnovzgojnih vsebin prepletale s političnimi, desetletja trajajoča razhajanja med obema organizacijama pa so se še zaostrile v času državljanskega spopada ter poglobila razdor v tradicionalnem taboru med drugo svetovno vojno.
Keywords: prva svetovna vojna, povojna moralna obnova, koncepti telesnosti, škof Anton Bonaventura Jeglič, Filip Terčelj, Sokol, Orel.

1572. The clock is ticking : understanding the ‘mixed feelings’ about fusion energy in EuropeChristopher R. Jones, Christian Oltra, Alessio Giacometti, Vanja Čok, Janez Povh, Urša Lamut, Gaston Meskens, Joke Kenens, Robbe Geysmans, Catrinel Turcanu, Zoltan Ferencz, Maria Teresa Orlando, Chiara Bustreo, 2024, original scientific article Abstract: If it can be made to work, fusion energy offers the potential for unlimited, clean energy. This prospect has seen substantial investment in the science and engineering behind fusion in order to demonstrate its viability. As key societal stakeholders, the opinions and actions of publics can shape the success of emerging energy technologies. To date, however, there have been relatively few studies focused on the public acceptability of fusion. The current study provides insight into public perspectives about fusion in five European countries (Belgium, Hungary, Italy, Slovenia and Spain). Using a qualitative ‘World Caf´ e’ type method, participants (n =10–25 per country) were provided with basic and balanced information about fusion, before being invited to discuss the risks, benefits and drawbacks of the technology and investment in its development. Transcripts from each World Caf´ e were subject to template analysis. The results indicated that while awareness of fusion was low in each country, participants were broadly supportive of fusion. This support was, however, tentative due to its commercially unproven nature. This stimulated questions about the value of investment in the technology, particularly given the urgency of addressing climate change. While there was some variation in the sub-topics raised and discussed in each country, the principal themes raised were broadly comparable. These findings add to our systematic understanding of the ‘mixed feelings’ held about fusion and have implications for future public engagement and communication efforts relating to the technology.

1576. Impacts of high PV penetration on Slovenia’s electricity grid : Energy Modeling and Life Cycle AssessmentJože Dimnik, Jelena Topić, Ante Čikić, Simon Muhič, 2024, original scientific article Abstract: The complexities of high PV penetration in the electricity grid in Slovenia based on targets proposed in national energy and climate plan were explored. Scenarios modeled an increase in installation power from 1800 MW in 2030 to 8000 MW in 2050. They were analyzed using energy modeling and life cycle assessment to assess the technical and environmental aspects of high PV grid penetration. The results showed that the increase in PV production from 2200 GWh (2030) to 11,090 GWh (2050) showed an unfavorable course of excess electricity in the system, resulting in the need for short-term and long-term storage strategies and exports of electricity. LCA analysis showed that penetration of a high share of PV results in a decrease in the impact category of global warming, which is higher in 2050 green scenarios that phase out coal and lignite electricity sources (80.5% decrease) compared to the 2020 baseline scenario. The increase in mineral resource scarcity can be observed with an increase in PV share when comparing the 2030 (50%) and 2050 (150%) BAU scenarios with the baseline scenario (2020). Factors such as environmental impacts, technical challenges, and the impact on the grid must be considered when implementing a decarbonization strategy.

1577. Milan Komar in Evgen Vasiljevič Spektorski - sopotnika preskoka iz prava v filozofijoBlaž Ivanc, 2019, original scientific article Abstract: Razprava obravnava zgodovinsko in filozofsko vez med zaslužnim profesorjem Katoliške univerze v Buenos Airesu in častnim senatorjem Univerze v Ljubljani dr. Milanom Komarjem (1921–2006) in profesorjem na več pravnih fakultetah (v Varšavi, Kijevu, Beogradu, Pragi in Ljubljani) ter rektorjem Univerze v Kijevu dr. Evgenom V. Spektorskim (1875–1951). Kot glavno ugotovitev razprave lahko najprej postavimo trditev, da je bil Evgen Spektorski v obdobju Komarjevega študija na Juridični fakulteti Univerze v Ljubljani njegov učitelj in mentor, ki ga je želel postaviti za svojega naslednika na stolici. Osebna vez med Komarjem in Spektorskim je po zaključenem Komarjevem doktorskem študiju prerasla tudi v prijateljsko vez. Med njunimi filozofskimi pogledi lahko opazimo ne le veliko sorodnost, temveč genetično povezanost.

1578. The Urnfield period Dragomelj I hoard : archaeological and chemical investigationsPeter Turk, David John Heath, Tea Zuliani, 2025, original scientific article Abstract: The hoard with over 86 kg of metal products unearthed in the settlement at Dragomelj is dated to Ha B1 and com-plements the remains of foundry activities in the nearby settlement at Podgorica. The twin settlements were centres of collection, production, and exchange located on the transport routes that connected the eastern Alpine copper mines with areas to the south. The products in the hoard include biconical ingots with a shaft hole that show a significant correlation between form and chemical composition, which is characterised by tin alloy and modest trace elements (Sb, Ni, As). In contrast, the biconical ingots without a shaft hole contain higher amounts of trace elements. This suggests that the Bronze Age smiths produced different forms of ingots to distinguish between the different metal compositions. The diverse composition of the ingots also indicates the different origins of the chalcopyrite and polymetallic ores used in the production process. The tin alloy of most biconical and some plano-convex ingots is the result of recycling or intentional addition of tin. The analysis of lead isotopes confirms the diverse origin of the objects. In addition to the probable source areas of Mitterberg and Trentino, the supply of copper ores from the nearby Karavanke Mountains remains a possibility.

1579. Fast transformation of PbTe using a multiphase mixture of precursors : first insightsHugo Rojas-Chávez, Nina Daneu, J. Manuel Juárez-García, 2025, original scientific article Abstract: For the first time, a mixture of PbTe and Pb- and Te-oxides coated with carbon, under electron beam irradiation (EBI), was transformed into quantum dots, nanocrystals, nanoparticles and grains of PbTe with a sintered appearance. A small portion of non-stoichiometric phases was also obtained. By selecting conditions that favor the instantaneous transformation, the Gibbs free energy barrier is lowered for obtaining different PbTe structures. The driving force associated with the high-energy milling requires 4 h of processing time to reach a complete transformation, while a high-energy source kinetically affects precursor surfaces to cause an abrupt global chemical transformation instantly. Importantly, the size of the PbTe structures increases as they approach the irradiation point, implying a growth process that is affected by the local temperature reached during the EBI. Imaging after the EBI process revealed morphological variations in PbTe, which can be attractive for use in thermoelectric materials. The results of this study provide the first insights into electron-beam-induced reactions using a multiphase mixture of precursors. Therefore, it is believed that this proposal can also be applied to obtain other binary semiconductor structures, even ternary ones.

1580. Alumina and hafnia thin films deposited by atomic layer deposition at different temperatures on biomedical stainless steel and titaniumIvan Spajić, Sandra Drev, Urška Trstenjak, Ingrid Milošev, 2025, original scientific article Abstract: Alumina and hafnia films produced by the atomic layer deposition were applied to commercially pure Ti and stainless steel 316L specimens for protection under simulated human body conditions. The ALD films were deposited at 180 °C and 260 °C to determine how the deposition temperature affect the films' protective properties. Surface analysis of the ALD films included scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The barrier properties were tested electrochemically using potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) techniques in a simulated body solution at 37 °C. Alumina thin films showed substantial barrier properties, but after 30 days of immersion, the alumina dissolved regardless of the deposition temperature. EIS tests themselves promoted the dissolution of alumina. In contrast, the barrier properties of hafnia depended significantly on deposition temperature. Hafnia deposited at 180 °C exhibited substantial protective properties and remarkable stability over an extended immersion period. However, when deposited at 260 °C hafnia films showed strong protection at the outset, but after a few days of immersion, they lost their protective ability due to porosity. The key factors affecting the barrier properties of ALD hafnia films were the proportion of the crystalline phase and how crystallites formed.
