1. The flux of UHECRs along the supergalactic plane using Pierre Auger Observatory dataArmando Di Matteo, Andrej Filipčič, Jon Paul Lundquist, Shima Ujjani Shivashankara, Samo Stanič, Serguei Vorobiov, Danilo Zavrtanik, Marko Zavrtanik, 2025, objavljeni znanstveni prispevek na konferenci Opis: We use the latest dataset from the surface detector array of the Pierre Auger Observatory, with events detected up to 31 December 2022 and a total exposure of 135,000 km² sr yr, to search for possible excesses in the flux of the most energetic cosmic rays on an intermediate angular scale (top-hat radius 27°, based on our previous results) from regions along the supergalactic plane. We find no indication for any such excesses other than the previously reported one in the Centaurus region, with a post-trial significance around 3σ, which we find extends down to lower energies than previously studied. In particular, the field of view of our dataset overlaps both regions in the northern celestial hemisphere from which excesses of events have been reported by the Telescope Array. With our integral exposures over these regions comparable to the Telescope Array ones, we find no indication of any flux excesses from there, with event counts in good agreement with the expectations from an isotropic distribution.

2. The Cherenkov Telescope Array view of the Galactic Center regionAion Viana, Christopher Eckner, Gašper Kukec Mezek, Samo Stanič, Serguei Vorobiov, Lili Yang, Gabrijela Zaharijas, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2019, objavljeni znanstveni prispevek na konferenci Opis: Among all the high-energy environments of our Galaxy, the Galactic Center (GC) region is
definitely the richest. It harbors a large amount of non-thermal emitters, including the closest supermassive black hole, dense molecular clouds, regions with strong star forming activity, multiple supernova remnants and pulsar wind nebulae, arc-like radio structures, as well as the base of what may be large-scale Galactic outflows, possibly related to the Fermi Bubbles. It also
contains a strong diffuse TeV gamma-ray emission along the Galactic ridge, with a disputed origin, including the presence of a possible Pevatron, unresolved sources, and an increased relevance of the diffuse sea of cosmic rays. This very rich region will be one of the key targets for the next generation ground-based observatory for gamma-ray astronomy, the Cherenkov Telescope Array (CTA). Here we review the CTA science case for the study of the GC region, and present the planned survey strategy. These observations are simulated and we assess CTA’s potential to better characterize the origin and nature of a selection of gamma-ray sources in the region.

3. Postnatal dynamics of Zeb2 expression in rat brain : analysis of novel 3′ UTR sequence reveals a miR-9 interacting siteKlara Kropivšek, Jasmine Pickford, David A. Carter, 2014, izvirni znanstveni članek Opis: ZEB2 is a transcription factor with established roles in neurogenesis but no defined function in postnatal brain despite extensive neuronal expression in telencephalic structures. Multiple, incompletely annotated transcripts derive from the Zeb2 locus; the purpose of the present study was to structurally characterize rat brain Zeb2 transcripts with respect to 3′ untranslated (UTR) sequence in order to understand Zeb2 transcript regulation including possible interactions with regulatory molecules such as neuronal miRNAs. We cloned a 5054-nucleotide Zeb2 3′ UTR that is included in the most abundant Zeb2 transcript in neonatal rat brain. Unique features of the distal 3′ UTR region included a number of brain-specific miRNA target sites; a highly conserved miR-9 target site at 3′ UTR position 4097 was selected for functional verification in transfection experiments. Parallel analysis of Zeb2 transcript, ZEB2 protein and miR-9 levels across postnatal brain cortical development revealed a significant accumulation of ZEB2 protein levels only between postnatal days P2 and P5 that was associated with an acute loss of postnatal miR-9 expression in cortex. These studies demonstrate novel features of Zeb2 gene expression in postnatal rat brain and highlight the importance of full transcript annotation for identifying the complement of potential transcript-interacting regulators.

4. European Film Co-productions with a Focus on Southeastern EuropeBoris Matić, 2022, magistrsko delo Opis: In this master thesis I shall deal with European film co-productions with an emphasis on the functioning of this form of film production in 6 countries of Southeast Europe. Starting from
defining the concept of co-productions and their types, short history, agreements that provide the legal framework for their establishment all the way to sources of funding from European
public national and supranational funds, broadcasters and production incentive systems. In other words, in this thesis I explain how this joint production adventure works in Europe, as
well as in the surrounding countries where I myself work as a film producer. The starting point of the paper is that the authors and producers hail from countries with low audiovisual capacity,
and due to high film production prices and lack of funding sources in these countries, they are almost forced to turn to international co-productions for more ambitious film projects. Through
the analysis and production study of Father, I speak about the application of the co-production model in filmmaking and the use of almost all types of available European sources of financial
closure, which is a successful example of cooperation between producers and filmmakers and collaborators from several European countries. In the practical part of my master’s thesis, I
briefly deal with the making of my short fiction film Thursday.

5. Geotourism in Arcos-Pains Karst Region, Minas Gerais, Brazil : dissertationMariana Barbosa Timo, 2021, doktorska disertacija Opis: Knowing the geological evolution of Earth surface allows identifying various natural attractions (biotic and abiotic). It makes possible the use of the most differentiated resources for the practice of tourism. The Arcos-Pains Karst Region has excellent potential for geotourism use. Examples of geosites include the Santuario and Brega Caves, the Dry Valley in the Corumbá region, and the Mastodonte Cave, where fossils of the Haplomastodon waringi mastodon species were found. However, public investment policies aiming at the environmental preservation of this heritage are still minimal or absent. The region also suffers tremendous anthropic pressure due to the extraction and processing of limestone, agribusiness, urban expansion and informal tourism. The process of inventorying and quantifying geosites is an essential tool for defining geoconservation strategies since it is not possible to protect all the geodiversity of the planet. The attributes analysed should integrate several criteria that take into account the intrinsic characteristics of each geosite, its potential use and the level of protection required. Regarding this research, the objective is approaching karst and speleological heritage, intending to define geosites for scientific, educational and tourist use at the Arcos-Pains Karst Region. The purpose of the inventory is to develop a geotourism project that provides essential information for better territorial management. It is also intended to assist environmental agencies in the enterprises’ environmental licensing processes installed in the region. Among the thirty-five (35) sites evaluated, eleven (11) presented above-average use-values in all categories analysed. Also, they presented national relevance and were classified as geosites. In addition to these, another sixteen (16) sites scored sufficiently to be categorised with national relevance. Within the geosites, one (1) was of international relevance: the São Francisco River Canyon. Considering the results, it is essential to deepen the research regarding karst dynamics to equalise geodiversity preservation while allowing its use to benefit society.

9. Bottom-up modelling of continuous renovation and energy balance of existing building stock: case study KočevjeMarjana Šijanec Zavrl, Gašper Stegnar, Andraž Rakušček, Henrik Gjerkeš, 2016, objavljeni znanstveni prispevek na konferenci Opis: A dynamic bottom-up model of the building stock is developed and implemented in a case study of Kočevje urban region. In the model, national register of real estate is cross-linked to data from other registers, e.g. the energy performance certificates (EPC) and the subsidized energy renovation measures. Regular updates of the data in registers enable continual improvement of the model. Therenovation potential is determined with respect to the age of building components after the last renovation, while the energy performance of the building stock is based either on the EPC for a
particular building if available or on the energy indicators of corresponding building type from IEE EPISCOPE building typology and IEE RePublic_ZEB. Thus, the bottom-up model of the building stock (BuilS) enable a profound overview of the total heat demand, final energy use and CO2 emissions of the entire stock.
In the case study Kočevje, various strategies for improving the buildings towards more sustainable ones are presented with projections to 2030. The strategies, reference and intensive renovation scenario, are compared with more ambitious strategy that the municipality is looking towards in the frame of Covenant of Mayors commitment. The bottom-up model was validated against the metered energy use of buildings connected to district heating. In the case study the model shows how the implementation of various strategies lead to different impacts and how the ambitious municipal plans are going to produce independence from fossil fuels by fostering the use of wood biomass as a locally
available sustainable energy supply. The Kočevje case study analysis demonstrates, at the local level how a concept of increasing renewable energy sources utilisation and building energy efficiency stimulated by progressive measures can respond to low carbon society and sustainable energy selfsupply challenges.
