1581. “Paste test” – a method for evaluating the fungal inhibition potential of ground wood samplesEli Keržič, Miha Humar, 2025, original scientific article Abstract: As part of the »ULTRA – University of Ljubljana for a Sustainable Society« project, a new test method was introduced into the curriculum to provide insight into key properties that affect wood durability. This study aimed to adapt and verify the “paste test”, which uses wood dust in nutrient media to assess the inhibitory effect of wood components on fungal growth. The method was adapted to match the available laboratory equipment and simplified for educational use by students at the Department of Wood Science and Technology (Biotechnical Faculty, University of Ljubljana, Slovenia). The study involved testing fungal growth on nutrient media supplemented with spruce wood dust, with the goal of evaluating different grinding methods, nutrient media, and data analysis. Potato dextrose agar nutrient media was confirmed as a suitable alternative to malt extract agar. The wood dust fraction size had no significant effect on fungal inhibition, enabling the use of coarser, less time-saving grinding methods. Image analysis and logistic growth modelling were conducted using freely available software (ImageJ and R-Commander), which proved to be effective alternatives to proprietary tools. Visualization of growth using logistic growth rates offered a clearer comparative analysis, despite some loss of dynamic growth information.
Keywords: inhibition, wood chemistry, nutrient media, white rot fungi, brown rot fungi, logistic growth rate

1582. Delovanje taborišča ŠentvidMiha Drobnič, 2018, original scientific article Abstract: V prispevku je obravnavano delovanje jugoslovanskega komunističnega taborišča za politične in vojne ujetnike, ki ga je v Škofovih zavodih v Šentvidu nad Ljubljano takoj po koncu druge svetovne vojne v maju 1945 ustanovila Ozna. Podrobnejši pregled režima taborišča Šentvid pokaže, da so se interniranci v njem spopadali z veliko prenatrpanostjo prostorov, s hudo lakoto, slabimi higienskimi razmerami, pogostimi zdravstvenimi težavami ter z najrazličnejšimi oblikami fizičnega in psihičnega nasilja. Nekateri ujetniki so posledično umrli že v taborišču, večina pa je bila brez sodnih postopkov odpeljana proti moriščem, zlasti tistim na območju Kočevskega roga. Edine številčnejše izpustitve, do katerih je prišlo po amnestiji v avgustu 1945, je v taborišču Šentvid dočakal le manjši delež internirancev.

1583. On the interplay between productively Menger and productively Hurewicz spaces in models of ▫$\mathfrak{b} = \mathfrak{d}$▫Dušan Repovš, Lyubomyr Zdomskyy, 2025, original scientific article Abstract: This article is devoted to the interplay between productively Menger and productively Hurewicz subspaces of the Cantor space. In particular, we show that in the Laver model for the consistency of the Borel's conjecture these two notions coincide and characterize Hurewicz spaces. On the other hand, it is consistent with CH that there are productively Hurewicz subspaces of the Cantor space which are not productively Menger.
Keywords: Menger space, Hurewicz space, Laver forcing, CH, preservation by products
