11. Digital twins and road construction using secondary raw materialsSebastjan Meža, Alenka Mauko Pranjić, Rok Vezočnik, Igor Osmokrović, Stanislav Lenart, 2021, izvirni znanstveni članek Povzetek: Secondary raw materials (SRMs) tend to be a valuable replacement for finite virgin materials especially since construction works (i.e., building and civil engineering work such as road construction) require vast quantities of raw materials. Using SRM originating from recycling a broad range of inorganic waste materials (e.g., mining waste, different industrial wastes, construction, and demolition waste) has been recognized as a promising, generally more cost-efficient, and environmentally friendly alternative to the exploitation of natural resources. Despite the benefits of using SRM, several challenges need to be addressed before using SRM even more. One of them is the long-term durability and little-known response of construction works built using such alternative materials. In this paper, we present the activities to establish a fully functioning digital twin (DT) of a road constructed using SRM. The first part of the paper is devoted to the theoretical justification of efforts and ways of establishing the monitoring systems, followed by a DT case study where an integrated data environment synthesizing a Building Information Model and monitored data is presented. Although the paper builds upon a small scale, the case study is methodologically designed to allow parallels to be drawn with much larger construction projects.

12. Using recycled material from the paper industry as a backfill material for retaining walls near railway linesKarmen Fifer Bizjak, Barbara Likar, Stanislav Lenart, 2021, izvirni znanstveni članek Povzetek: The construction industry uses a large amount of natural virgin material for different geotechnical structures. In Europe alone, 11 million tonnes of solid waste is generated per year as a result of the production of almost 100 million tonnes of paper. The objective of this research is to develop a new geotechnical composite from residues of the deinking paper industry and to present its practical application, e.g., as a backfill material behind a retaining structure. After different mixtures were tested in a laboratory, the technology was validated by building a pilot retaining wall structure in a landslide region near a railway line. It was confirmed that a composite with 30% deinking sludge and 70% deinking sludge ash had a high enough strength but experienced some deformations before failure. Special attention was paid to the impact of transport, which, due to the time lag between the mixing and installation of the composite, significantly reduced its strength. The pilot retaining wall structure promotes the use of recycled materials with a sustainable design, while adhering to government-mandated measures.

16. International Interdisciplinary Symposium Surviving the Anthropocene: Towards Elemental Literacy and Interdisciplinary Partnerships : online, May 24-26, 2021 : programme and abstracts2021, druge monografije in druga zaključena dela Povzetek: Knjiga povzetkov mednarodnega interdisciplinarnega simpozija Preživeti dobo antropocena: k elementalni pismenosti in interdisciplinarnim partnerstvom predstavlja prispevke, ki združujejo inovativno g/lokalno vedenje s področij filozofije in pedagogike, ekofeminizma, politike, teologije, biosocialnih kulturnih študij ter teorij in praks utelešenega kritičnega mišljenja, z namenom oblikovanja pravičnih in realističnih načinov življenja na Zemlji, ki bodo omogočili preživetje Antropocena. Žarišče je sodeljeno z naravnim okoljem, ki ga razumemo kot čutečega partnerja z vrednotami, ki presegajo zgolj komodifikacijo in gospodarske okvire. S pripoznavanjem naravnega okolja kot dejavnika v lastnem postajanju, si simpozij prizadeva zadihati z naravo kot njen sopotnik. Nadalje si snovalke in snovalci simpozija z novim konceptualnim razmišljanjem in sodelovanjem, ki zagovarja elementalno filozofijo povezovanja in spoštovanja, prizadevamo za boljše razumevanje in razrešitev nasprotij med naravo, kulturo, etiko in politiko. Razvijanje elementalne pismenosti za prenos sodobnega razumevanja, kaj je narava, kako se nanjo vpliva in kako deluje, je osrednje stičišče prispevkov simpozija, ki si želi zamišljati in dinamično sodelovati v novih, kompleksnih in prilagodljivih možnostih, izzivih in reformah okoljskega upravljanja, ter filozofskih analizah obnovitvenih usmeritvah ekološke pravičnosti, tako konceptualno kot praktično.

17. Worldwide genetic structure elucidates the Eurasian origin and invasion pathways of Dothistroma septosporum, causal agent of Dothistroma needle blightMartin S. Mullett, Rein Drenkhan, Kalev Adamson, Piotr Boroń, Anna Lenart-Boroń, Irene Barnes, Michal Tomšovský, Zuzana Jánošíková, Katarína Adamčíková, Emília Ondrušková, Barbara Piškur, Tine Hauptman, 2021, izvirni znanstveni članek Povzetek: Dothistroma septosporum, the primary causal agent of Dothistroma needle blight, is one of the most significant foliar pathogens of pine worldwide. Its wide host and environmental ranges have led to its global success as a pathogen and severe economic damage to pine forests in many regions. This comprehensive global population study elucidated the historical migration pathways of the pathogen to reveal the Eurasian origin of the fungus. When over 3800 isolates were examined, three major population clusters were revealed: North America, Western Europe, and Eastern Europe, with distinct subclusters in the highly diverse Eastern European cluster. Modeling of historical scenarios using approximate Bayesian computation revealed the North American cluster was derived from an ancestral population in Eurasia. The Northeastern European subcluster was shown to be ancestral to all other European clusters and subclusters. The Turkish subcluster diverged first, followed by the Central European subcluster, then the Western European cluster, which has subsequently spread to much of the Southern Hemisphere. All clusters and subclusters contained both mating-types of the fungus, indicating the potential for sexual reproduction, although asexual reproduction remained the primary mode of reproduction. The study strongly suggests the native range of D. septosporum to be in Eastern Europe (i.e., the Baltic and Western Russia) and Western Asia.
