12. Toksikološka analiza vsebine vojaških čutar, zakopanih 70 let v kraški jami na Kočevskem, JV SlovenijaJanez Mulec, Sara Skok, Vesna Zalar Serjun, Andrej Mihevc, 2019, original scientific article Abstract: Za odkrivanje ostankov materialnih sledi se na dobro ohranjenih predmetih lahko opravijo forenzične preiskave. V Breznu v Debliških livadah je bilo odkritih večje število predmetov, ki so bili odvrženi v jamo v maju in juniju 1945. Med odkritim materialom so bile tudi vojaške čutare. Nekatere izmed čutar so še vsebovale tekočino, nekatere pa tudi poltrdo, gelasto oborino. Tekočina in oborina iz čutar sta vsebovali kovine, ki so se najverjetneje s časom izlužile iz kovinske posode. Korozija čutar nakazuje prisotnost minerala hematita. Vsebina čutar je nadalje vsebovala nekaj raztopljene organske snovi (celotni organski ogljik – TOC v tekočini 9,22 mg/l, v tekočini ekstrahirane oborine 34,1 mg/l), nekaj mikrobne biomase ter relativno visoke koncentracije nitrata (240 mg/l v tekočini, 55 mg/l v ekstrahirani oborini) in sulfata (18mg/l v tekočini, 836 mg/l v ekstrahirani oborini). Bakterijskih indikatorjev, Escherichia coli in enterokokov, ki bi kazali na fekalno kontaminacijo vsebine, v vzorcih nismo zaznali. Raztopina in oborina sta izkazovali podobno stopnjo toksičnosti, okrog 20%inhibicijo bioluminiscence bakterije Vibrio fischeri. Glede na Pravilnik o pitni vodi tekočina s sedanjimi kemijskimi lastnostmi ni primerna za uživanje. Rezultati ne kažejo nujno na toksičnost izvornih tekočin iz časa, ko so bile čutare odvržene v jamo, ampak bi se toksičnost lahko razvila postopoma zaradi izluževanja kovin iz posode, zlasti aluminija, in (bio)kemijskih reakcij. Navkljub stabilnim jamskim razmeram, ki so jim bile izpostavljene čutare, ugotovljeni parametri ne podpirajo dolgoročne ohranitve stabilne DNA za morebitne nadaljnje forenzične analize.

15. Recovery of phosphorus and metals from the ash of sewage sludge, municipal solid waste, or wood biomass : a review and proposals for further useSara Tominc, Vilma Ducman, Wolfgang Wisniewski, Terttu Luukkonen, Kirkelund Gunvor M., Ottosen Lisbeth M., 2023, original scientific article Abstract: This review provides an overview of methods to extract valuable resources from the ash fractions of sewage sludge, municipal solid waste, and wood biomass combustion. The resources addressed here include critical raw materials, such as phosphorus, base and precious metals, and rare earth elements for which it is increasingly important to tap into secondary sources in addition to the mining of primary raw materials. The extraction technologies prioritized in this review are based on recycled acids or excess renewable energy to achieve an optimum environmental profile for the extracted resources and provide benefits in the form of local industrial symbioses. The extraction methods cover all scarce and valuable chemical elements contained in the ashes above certain concentration limits. Another important part of this review is defining potential applications for the mineral residues remaining after extraction. Therefore, the aim of this review is to combine the knowledge of resource extraction technology from ashes with possible applications of mineral residues in construction and related sectors to fully close material cycle loops.

16. Methodology for evaluating the CO2 sequestration capacity of waste ashesSara Tominc, Vilma Ducman, 2023, original scientific article Abstract: The concentration of CO2 in the atmosphere is constantly increasing, leading to an increase in the average global temperature and, thus, affecting climate change. Hence, various initiatives have been proposed to mitigate this process, among which CO2 sequestration is a technically simple and efficient approach. The spontaneous carbonation of ashes with atmospheric CO2 is very slow, and this is why accelerated carbonation is encouraged. However, not all ashes are equally suitable for this process, so a methodology to evaluate their potential should be developed. Such a methodology involves a combination of techniques, from theoretical calculations to XRF, XRD, DTA-TG, and the calcimetric determination of the CaCO3 content. The present study followed the approach of exposing ashes to accelerated carbonation conditions (4% v/v CO2, 50–55% and 80–85% RH, 20 ◦C) in a closed carbonation chamber for different periods of time until the maximum CO2 uptake is reached. The amount of sequestered CO2 was quantified by thermogravimetry. The results show that the highest CO2 sequestration capacity (33.8%) and carbonation efficiency (67.9%) were obtained for wood biomass bottom ash. This method was applied to eight combustion ashes and could serve to evaluate other ashes or comparable carbon storage materials.

17. Dataset for the article Methodology for evaluating the CO2 sequestration capacity of waste ashesVilma Ducman, Sara Tominc, 2023, complete scientific database of research data Abstract: The dataset supports the data in the tables and figures in the article Methodology for evaluating the CO2 sequestration capacity of waste ashes (doi: 10.3390/ma16155284). It contains the original masses of waste ash before and during carbonation treatment, the sequestered CO2 masses after carbonation treatment, mass uptake calculations, calcimetric measurements, calculations of theoretical maximum sequestered CO2 (based on XRF results) and carbonation efficiency (CE), original results of DTA/TG analysis of individual ashes, original results of XRF measurement and data from XRD analyses supported by X-ray diffractograms not published in the article.

18. Dinamika dolžine telomerov v levkocitih po zdravljenju z obsevanjem pri raku dojkTanja Marinko, Sara Redenšek Trampuž, Ana Trstenjak, Vita Dolžan, Katarina Trebušak Podkrajšek, Katja Goričar, 2023, published scientific conference contribution Abstract: Obsevanje je del standardnega zdravljenja bolnic z rakom dojk. Odgovor na zdravljenje z obsevanjem je pri vsakem posamezniku drugačen in je odvisen tudi od genetskih dejavnikov. Eden od novejših genetskih označevalcev odgovora na obsevanje je dolžina telomerov. Telomeri ščitijo kromosome pred krajšanjem in vzdržujejo genomsko stabilnost. Rezultati naše raziskave kažejo, da se dinamika spreminjanja dolžine telomerov takoj po zdravljenju z obsevanjem in v šestih mesecih po obsevanju pri bolnicah z neinvazivnim rakom dojk spreminja in bi lahko služila kot biološki označevalec odgovora na obsevanje. Molekularni mehanizmi, povezani s tem procesom, ostajajo zaenkrat večinoma neraziskani.
