1231. Korpusni vpogled v nestandardno spletno slovenščino : novi samostalniki in semantični premiki v komentarjih družbenih omrežij (JANES v1.0): raziskovalni podatkiMaša Rolih, zaključena znanstvena zbirka raziskovalnih podatkov Povzetek: Zbirka vsebuje raziskovalne podatke o novih in releksikaliziranih samostalnikih v nestandardni spletni slovenščini, izluščenih iz korpusa JANES v1.0 (2014–2018). Vključeni so izrazi, ki niso evidentirani v osrednjih slovarskih virih (SSKJ, SP, eSSKJ, SNB, Sprotni slovar), ter samostalniki s semantičnimi premiki v sodobni rabi. Za vsako enoto so navedeni samostalniška oblika, kvalifikatorji (npr. neform., manj form., mlad., avtomobil., polit., splet., mod., glasb., šport., slabš., evfem., vulg., šalj., ekspr.), pomen v kontekstu in konkordančni primer iz korpusa. Podatki so bili pridobljeni z avtomatskim luščenjem samostalnikov v orodju noSketch Engine in nato filtrirani glede na frekvenco, prisotnost v slovarskih virih ter diskurz. Pri tem je bila upoštevana predvsem raba v spletnih forumih in družbenih omrežjih, kjer je pogosta tvorba novih samostalnikov ali pomenskih premikov. Zbirka omogoča vpogled v dinamiko sodobne nestandardne slovenščine in je osredotočena na tiste leksikalne enote, ki kažejo spremembe v besedotvorju, semantiki in pragmatično-ekspresivni rabi.

1233. Enumerating the number of $k$-matchings in successively amalgamated graphsSimon Grad, Sandi Klavžar, 2026, izvirni znanstveni članek Povzetek: In this paper, the transfer matrix technique using the $k$-matching vector is developed to compute the number of $k$-matchings in an arbitrary graph which can be constructed by successive amalgamations over sets of cardinality two. This widely extends known methods from the literature developed for computing the number of $k$-matchings in benzenoid chains, octagonal chains, cyclooctatetraene chains, and arbitrary cyclic chains. Two examples demonstrating how the present method can be applied are given, one of them being an elaborated chemical example.

1237. Geokemični atlas MariboraMartin Gaberšek, 2025, znanstvena monografija Povzetek: Poznavanje prostorske porazdelitve vsebnosti kemičnih elementov v tleh je bistveno za zagotavljanje varnega in zdravega bivalnega okolja ter pomembno za prostorsko načrtovanje, posege v prostor in spremljanje dolgoročnih antropogenih vplivov na okolje. Zaradi velikega števila prebivalcev je to še posebej pomembno v urbanih okoljih. V monografiji podajamo rezultate raziskav vsebnosti kemičnih elementov, pH vrednosti in vsebnosti celotnega ter organskega ogljika v tleh v Mariboru in prikaze njihovih prostorskih porazdelitev z geokemičnimi kartami. Vzorčili smo zgornjih 10 cm tal po celotnem Mariboru v mreži 500 × 500 m. Po razklopu z zlatotopko smo z ICP-MS analizirali vsebnosti 65 elementov. Rezultati kažejo, da tla na območju Maribora niso močno obremenjena s potencialno strupenimi elementi, odkrili smo le manjša območja in nekatere izolirane lokacije z visokimi vsebnostmi bakra (Cu), svinca (Pb) in cinka (Zn), predvsem znotraj industrijskih območij ter starega mestnega jedra. Njihove mediane, ki so nekoliko nad slovenskimi, velika variabilnost v vsebnostih in prostorska porazdelitev kažejo na vsaj deloma antropogen izvor. Deloma antropogen izvor lahko pripišemo tudi kadmiju (Cd), antimonu (Sb), kositru (Sn), živemu srebru (Hg) in srebru (Ag). Nekateri preostali elementi, kot so aluminij (Al), kobalt (Co), krom (Cr), železo (Fe) in vanadij (V) jasno odražajo prevladujoč vpliv geološke podlage. S predstavljeno raziskavo smo želeli opredeliti trenutno geokemično stanje tal v Mariboru, približati rezultate splošni javnosti in omogočiti dolgoročno spremljanje stanja tal ter okolja na splošno.

1238. Effects of groundwater flow on end-temperature of closed-loop systems used for coolingSimona Adrinek, Joerg Prestor, Simona Pestotnik, Nina Rman, 2025, izvirni znanstveni članek Povzetek: Stable subsurface temperatures provide a reliable source of shallow geothermal energy. This research is one of a few that investigates the potential of closed-loop systems for cold storage facilities. We listed 47 cold storage facilities in Slovenia and evaluated the capacity of two 50 m deep borehole heat exchangers that would penetrate one of five intergranular aquifers. As the Slovenian legislation does not define temperature thresholds of the heat carrier fluid, we applied – 3 °C and +24 °C as conservative boundary conditions. First, we quantified the possible amount of injected waste heat with the analytical model (EED) using seven scenarios. Further, we upgraded our results with the three scenarios in the numerical model (FEFLOW), including groundwater flow. The calculation revealed that the optimal natural conditions for geothermal cooling of cold storages are in the Sava Basin, where fast groundwater flow (7.2 m/day) increases possible injected heat in numerical calculation to more than 900 % compared to analytical calculation. Cooling capacities decrease from the Sava to Drava, Mura, Savinja and Krško Basins. Our research quantitatively confirms that areas with groundwater flow are more conductive to restoring underground temperatures through the injection of waste heat from cooling cold storages than areas without groundwater flow.

1240. Development of cellulose-degrading lactic acid bacterium Lactococcus cremoris by genetic engineeringPetra Štravs, Hélène David, Henri-Pierre Fierobe, Aleš Berlec, 2025, izvirni znanstveni članek Povzetek: Cellulose is one of the most abundant potential sources of carbon for sustainable microbial production of biochemicals. Lactic acid bacteria that produce a range of valuable metabolites are generally unable to grow on cellulose. Here, we aimed to develop the lactic acid bacteria Lactococcus cremoris for growth on cellulosic substrate. Genes encoding cellulases Cel5I, Cel9A and Cel5H from different cellulolytic bacteria were introduced into L. cremoris NZ9000 strain. The genes were designed for constitutive expression, with the produced cellulases being either secreted or displayed on the cell surface. Four promoters for cellulase gene expression and two noncovalent anchors for surface display of cellulases were evaluated using immunoblotting, confocal microscopy and flow cytometry. With the most effective promoter PepN, the cells secreted milligram amounts of cellulases per liter culture. The highest cellulolytic activity on amorphous (phosphoric-acid swollen cellulose, PASC) and microcrystalline (Avicel) cellulose was observed for the secreted Cel5H and Cel5I cellulases, respectively. The major cellodextrin produced by Cel5H and Cel5I was cellobiose, as determined by high performance anion exchange chromatography. The strains secreting cellulases outperformed the corresponding strains displaying the same cellulase on the surface in growth on PASC as the primary carbon source. The fastest growth was observed for the strain secreting Cel9A, followed by strain secreting Cel5H. By demonstrating growth of lactic acid bacteria expressing heterologous cellulases on PASC as a major carbon source for the first time, this study presents an important step towards the realization of consolidated bioprocesses involving lactic acid bacteria.
