Abstract: The contribution of exposed mass timber to compartment fire dynamics is often framed by prescribed fuel load density, implicitly assuming fuel-independent thermal feedback. This paper interrogates that assumption experimentally using full-scale cross-laminated timber (CLT) compartments with two exposed surfaces (ceiling and side wall) and a movable fuel; either a kerosene pool or a wood crib. High-resolution measurements of heat flux, in-depth timber temperatures, burning rates, opening flows, and gas species demonstrate that fuel chemistry and geometry strongly modulate oxidizer delivery and residence time, thereby governing radiative feedback, CLT burning rates, and external flaming. The pool fire exhibited pronounced radiative enhancement and transient oxidizer starvation near the timber until pool decay. In contrast, the crib burning rate was inhibited, while the CLT burned efficiently. Analysis of the Global Equivalence Ratio (GER) and air bypass ratio revealed significant excess oxygen in the outflow, indicating that entrained air did not permeate the crib but instead oxidized the CLT, leaving unreacted air due to short mixing timescales. Despite unchoked doorway conditions, the crib fire produced bypass ratios and external flaming fractions comparable to the pool fire. The work shows that fuel load and ventilation factors alone are insufficient to describe the mass timber compartment fire dynamics and the CLT performance (e.g. charring). The fuel chemistry, geometry, and placement interact significantly with the compartment geometry. Therefore, the role of the moveable fuel is fundamental, and care must be employed when extrapolating demonstrator experiment results to the fire safety design of mass timber buildings.

Abstract: Despite Slovenia’s ethnically heterogeneous landscape, the Constitution recognizes only two groups as “autochthonous national communities”: the Hungarians and the Italians. Whereas the Roma also enjoy some constitutional protection, the most numerous ex-Yugoslav ethnic groups, also known as “new communities” (Albanians, Bosniaks, Croats, Macedonians, Montenegrins, and Serbs), received legal recognition only recently. Neither the “new communities” nor the German-speaking population, however, benefit from the protection of the Council of Europe’s Framework Convention for the Protection of National Minorities – regardless of the former’s substantial numbers and the latter’s historic presence on the territory of the State. This paper first gives a detailed overview of Slovenia’s legislation related to the concept of minorities and then evaluates it in light of the monitoring materials of the Advisory Committee of the Framework Convention, as well as those of the UN treaty bodies. The aim of the paper is to assess whether the Slovenian system is in conformity with the international obligations of the State, at least from a conceptual point of view. Based on a thorough analysis of some 30 documents adopted by international monitoring bodies, the answer seems to be negative, which may come as a surprise when contrasted with the strong international reputation of the Slovenian system of minority protection. This paper demonstrates that Slovenia has been adamantly and repeatedly criticized for retaining the undefined and confusing concept of “autochthony”; for adopting a restrictive approach to the recognition and provision of special protection for different ethnic groups; for making unjustified and arbitrary distinctions between “autochthonous” and “non-autochthonous” Roma communities; and for the fact that it has still not managed to definitively resolve the issue of the “erased”.

Abstract: Introduction: C5 inhibitor (C5i) therapy markedly increases susceptibility to invasive meningococcal disease (IMD) by blocking the terminal complement pathway essential for defense against Neisseria meningitidis. Vaccination is recommended for all recipients, yet breakthrough infections persist. Antibiotic prophylaxis is not universally endorsed, resulting in variable practices. We aimed to assess whether antibiotic prophylaxis provides additional protection beyond vaccination in C5i-treated patients. Methods: The analysis included 124 C5i recipients treated for > 6 months. Patients were classified as receiving single protection (vaccination or antibiotic prophylaxis alone) or combined protection (vaccination and continuous antibiotic prophylaxis). The outcomes were analyzed by prescribed and by implemented regimen; the latter accounting for patient adherence to antibiotic prophylaxis. Results: Of the patients, 60% were prescribed combined protection. Booster vaccination coverage was low (< 40%), and one-quarter of patients did not adhere to antibiotic prophylaxis. The overall incidence of IMD was 0.74 cases per 100 patient-years (PY) (95% confidence interval [CI]: 0.37–1.32). After accounting for noncompliance, the incidence of IMD remained significantly lower in the combined protection group (3.1 [95% CI: 1.5–4.8] vs. 0.5 [95% CI: 0.0–2.7], P = 0.03), corresponding to a 6-fold reduction in risk. Eleven infections were reported, predominantly because of serogroup B (45.5%). Ten patients recovered completely, and 1 had mild residual disability. Conclusion: Although guidelines recommend vaccination alone, our findings indicate that combined protection offers substantially greater protection against IMD in patients receiving long-term C5i. Continued prospective monitoring will be essential to define the optimal preventive strategies in this high-risk population.

Abstract: Traditional agricultural plant pest and disease management practices are based on visible characteristics and require that plants are checked individually, making these practices time consuming and therefore costly. Plant pests and diseases also often exhibit a heterogeneous distribution, making detection more difficult. Remote sensing methods enable comparatively accurate detection of pests and diseases over larger areas. Furthermore, because remote sensing sensors utilize light outside the human visible spectrum, presymptomatic detection becomes possible, thus facilitating timely, appropriate and spatially accurate management practices. Because remote sensing systems generate large amount of data, novel data analysis methods, such as machine learning, were introduced to plant protection. While pest and disease detection is possible using individual sensors, best results can be obtained by combining different sensors, utilizing different spectral ranges or physiological responses to light. A large amount of data and information has been generated in the past, but this research has mostly been focused on individual pathogens. Future research will have to focus on combined infections or infestations, and include abiotic stressors as well.

Abstract: Field studies in 2022–2024 and the checking of collection of the Natural History Museum of Montenegro revealed seven new national species records for Montenegro: Chara corfuensis Groves ex Fil., C. galioides DC., C. squamosa Desf., Sphaerochara intricata (Trentep. ex Roth) Feist-Castel & N. Grambast, Tolypella hispanica Nordst. ex Allen, T. nidifica (O. F. Müll.) A. Braun and “Mediterranean Chara”. The checking of the specimens stored in ZE Botanischer Garten und Botanisches Museum, Freie Universität Berlin, Komarov Botanical Institute of RAS , and Naturhistorisches Museum Wien revealed old specimens of C. galioides, a new species for Croatia, and new sites of T. hispanica for Greece. The field research in Cyprus resulted in a new national species record of C. squamosa. New data enriched knowledge about the distribution of charophytes in Central and Eastern Mediterranean and Southeast Europe and allowed tentative suggestions of important charophyte areas in Montenegro. The tentative evaluation of species protection statuses was implemented here. The updated species list of Montenegrin charophytes counted 37 species making Montenegro one of the charophyte species-rich countries in Europe.
