2. Microstructural analysis of tungsten single crystals irradiated by MeV W ionsJanez Zavašnik, Andreja Šestan, Thomas Schwarz-Selinger, Esther Punzón Quijorna, Mitja Kelemen, Jan Predrag, Sabina Markelj, 2025 Opis: We investigated the microstructural evolution of W(111) single crystals under high-energy self-ion irradiation at 290 K and 800 K, using complementary characterization techniques, including Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Rutherford backscattering spectrometry in channelling regime (RBS-C), Positron annihilation spectroscopy (PAS), and Nuclear reaction analysis (NRA). Irradiation with MeV W ions allowed for controlled defect formation, with dose and temperature significantly affecting defect type and distribution. At 290 K, interstitial defects evolved from dislocation loops at low doses (0.02 dpa) to dislocation networks at higher doses (0.2 dpa). In contrast, at 800 K, lower dislocation densities were observed, with nm-sized dots and isolated lines forming at 0.02 dpa and developing into longer dislocation lines (~30 nm) at 0.2 dpa. RBS-C spectra support these findings, showing a trend of increasing dislocation density with dose but decreasing with temperature. PAS analyses revealed mono-vacancies and small vacancy clusters (V2–V4) at 290 K, coalescing into larger clusters (V25–V50) at 800 K. NRA measurements indicated greater deuterium retention at 290 K than at 800 K, consistent with lower vacancy mobility at the lower temperature. Combined TEM, RBS-C, PAS, and NRA observations highlight increased vacancy mobility and defect recombination with temperature, forming larger vacancy clusters at 800 K. This comprehensive study provides quantitative insights into defect formation and evolution in W single crystals, presenting a comparative analysis of defect distributions across multiple techniques and revealing temperature-dependent mechanisms of microstructural change.

4. Izbira tehnologije strojne sečnje in spravila lesa na strmih terenihLuka Pajek, Janez Krč, 2025 Opis: Zaradi potrebe po vse večji humanizaciji dela in vsesplošnem pomanjkanju delavcev, se povečuje delež strojne sečnje in spravila lesa tudi na strmih terenih. Analizirali smo možnost uporabe različnih tehnoloških rešitev za delo na strmih terenih. Nabor in vrednotenje tehnoloških rešitev smo povzeli po nemški raziskavi (Findeisen, 2008). Na podlagi primerjave razpoložljivih modelov tehnoloških rešitev smo v prvi fazi izmed 19 izbrali pet modelov: 1) stroj za sečnjo in zgibni polprikoličar, 2) stroj za sečnjo z gosenicami in zgibni polprikoličar z vitlom za povečanje oprijema, 3) model z motorno žago, strojem za sečnjo z gosenicami in zgibni polprikoličar z vitlom za povečanje oprijema, 4) model v kombinaciji žičnice in motorne žage ter 5) sedlasti traktor s procesorsko glavo. Dodali smo še model 6) model z motorno žago, strojem za sečnjo z vitlom za povečanje oprijema in zgibni polprikoličar z vitlom za povečanje oprijema, ker je bil v preteklosti že uporabljen na izbranem delovišču. Glede na razmere na konkretnem delovišču smo izbranim modelom prve faze ocenili njihovo primernost po treh vidikih (ergonomski, okoljski in ekonomski). Za izbrane modele smo izračunali strošek dela, kjer smo upoštevali popravke cene dela, ki izhajajo iz razmer za izvedbo del na delovišču. Rezultati so pokazali, da je za analizirano delovišče najprimernejši model 6, ki omogoča sečnjo debelih dreves na velikih naklonih in izvedbo del na vsej površini delovišča. Medsebojna primerjava različnih tehnoloških rešitev in posledično izbor najbolj primernega tehnološkega modela v danih razmerah je sicer pilotna, a jo ocenjujemo kot koristno pomoč pri načrtnem in uspešnem uvajanju sodobnih tehnologij v slovensko gozdarstvo.

5. L-FABP as a potential biomolecular marker of liver graft injuryAna Kalamutova, Danaja Plevel, Mihajlo Djokić, Aleš Jerin, Blaž Trotovšek, Miha Petrič, 2025 Opis: Background: In recent years, indications for liver transplantation have expanded, while the age of transplant recipients has significantly increased due to improvements in perioperative management. As clinical manifestations of posttransplant complications vary and are often nonspecific, the identification of appropriate biomarkers is important for the assessment of graft quality and early recognition of potential complications following liver transplantation. Liver-type FABP (L-FABP) is a small cytoplasmic protein found abundantly in hepatocytes and is involved in the intracellular transport of long-chain fatty acids. Elevated serum levels have been detected in acute and chronic liver failure, kidney failure, and some malignancies. Materials and Methods: We conducted a prospective, single-center study from July 2023 to January 2025, including 29 adult patients who underwent deceased-donor transplantation. Three patients were excluded due to inadequate sample withdrawals. Serum L-FABP was measured preoperatively and on postoperative days 1, 3, 5, 7, and 14. Clinical, surgical, and biochemical data were collected and analyzed using non-parametric statistical tests. Results: L-FABP levels were significantly higher on POD 7 in recipients of grafts from donors ≥ 65 years (p = 0.035), with no corresponding changes in standard liver function markers. While no significant differences in L-FABP levels were found between patients with and without infectious biliary or vascular complications (all p > 0.05), we proved a strong negative correlation between intraoperative blood transfusion volume and L-FABP levels on POD 5 (ρ = −0.677, p < 0.001) and POD 7 (ρ = −0.455, p = 0.025). Conclusions: Our findings suggest that L-FABP holds promise as a biomarker for the early detection of subclinical hepatic graft cellular injury, which is not detected by means of conventional biomarkers for liver function.

6. Prevedba ocen kakovosti stoječih dreves na izbranih objektih v sortimentno strukturoLuka Krajnc, Janez Zafran, 2025 Opis: V raziskavi je bila predstavljena in preračunana ocena kakovosti stoječih dreves v sortimentno strukturo. Na 123 drevesih štirih drevesnih vrst je bila opravljena primerjava med dejansko sortimentacijo po poseku in računsko sortimentacijo na osnovi predhodno ocenjene kakovosti. Izmerili smo 869 gozdno-lesnih sortimentov ter primerjali rezultate računske in dejanske sortimentacije. Rezultati so pokazali dobro ujemanje pri smreki, nekoliko manj pa pri listavcih, kjer je bil večji vpliv notranjih napak na sortimentno sestavo. Metoda je praktično uporabna in daje uporabne rezultate za napoved sortimentne sestave. Izboljšati je treba še modele napovedi velikosti grč, s čimer bi natančnost napovedi še dodatno povečali.

9. Influenza vaccine uptake in juvenile idiopathic arthritis during the COVID-19 pandemicDespoina Maritsi, Noa Alpert, Maša Bizjak, Amit Ziv, Barbora Balažiová, Nataša Toplak, 2025 Opis: Background: Children with rheumatic diseases are at risk for contracting severe influenza and COVID-19 and are thus targeted for these vaccination. Objectives: To assess the influenza (flu) vaccination rate in children with Juvenile Idiopathic Arthritis (JIA), investigate families’ attitudes towards the influenza vaccine, and the effect of the COVID-19 pandemic on flu vaccine uptake. Methods: This multi-centre, cross-sectional study was conducted across 9 countries. JIA caregivers completed an anonymous questionnaire about their children’s influenza vaccination, including the 2019–2020 and 2020–2021 seasons, including knowledge, and perceptions regarding influenza vaccination. Results: Based on responses from 655 JIA caregivers, 152 children (23.2%) received influenza vaccinations in the 2020–2021 season, representing a significant rise from 18.6% in the previous season (p < 0.01). The likelihood of vaccination was higher among employed/self-employed caregivers compared to unemployed (28.2% and 29.9% vs. 13.9%), and those with tertiary education versus elementary (28% vs. 9.7%), both p < 0.01. Concerns of children’s vulnerability to SARS-CoV-2 and severe COVID-19 disease due to JIA were prevalent (51.3% and 85.3% respectively), with 51.3% supporting COVID-19 vaccination. Caregivers who previously vaccinated their children for influenza showed a greater inclination towards SARS-CoV-2 vaccination (73.4% and 79.5%, p < 0.01). Conclusions: Families of children with JIA reported an increasing flu vaccine uptake and a high intention for COVID- 19 vaccine administration. Previous vaccination behavior was shown as a significant predictor of future behaviour. Strengthening health education may address fears and lead to better vaccine coverage against both influenza and SARS-CoV-2 in children with JIA and other inflammatory rheumatic diseases.

10. Rare Basidiomycete resupinatus rouxii reported for the first time in Türki̇yeIsmail Acar, Halide Karabiyik, 2025 Opis: In this study, Resupinatus rouxii Consiglio & Setti was collected from Çanakkale province, Türkiye, and identified using both morphological and molecular data. Macroscopically, the species is characterised by its small size, kidney-shaped pileus, light grey colour, and slightly hairy surface. Microscopic examination confirmed diagnostic features of the genus Resupinatus, and detailed evaluations were made of the basidia, basidiospores, and cystidia. The internal transcribed spacer (ITS) region of nuclear ribosomal DNA was sequenced and used in phylogenetic analyses. The resulting ITS sequence showed more than 99% similarity to the reference sequence of R. rouxii, supporting the morphological identification. This study represents the second scientific report of R. rouxii worldwide and provides the fourth known record of this species, extending its known distribution to Türkiye (Çanakkale province) and contributing valuable data to its biogeography.
