2. Identification and detailed characterization of ▫$PM_10$▫ sources in an Alpine valley influenced by a cement plantKristina Glojek, Katja Džepina, Griša Močnik, 2023, objavljeni povzetek znanstvenega prispevka na konferenci Opis: The contribution of traffic and wood burning to particulate matter (PM) across the Alps is widely recognized and studied (Herich et al., 2014 and references therein; Glojek et al., 2020). However, studies on valleys with cement production are scarce (Kim et al., 2003; Rovira et al., 2018) despite its large PM emissions and potential toxic properties (Erik et al., 2022; Weinbruch et al., 2023). We aim to identify and characterize sources’ contribution to the complex mixture of carbonaceous and mineral PM10 in a representative Alpine valley.
Quartz filter samples of PM10 were collected daily from December 2020 to December 2021 and analyzed using different chemical techniques. In the same period equivalent black carbon (eBC) measurements were taken with the Aethalometer AE43. The measured species were analyzed using Positive Matrix Factorization (PMF) model (EPA PMF 5.0) with newly added tracers, i. e. source-specific eBC (Sandradewi et al., 2008) and organic species (2-MT, 3-MBTCA, phtalic acid, MSA and oxalate). The final PMF results were compared to online PMF-factors (SoFi Pro) derived from PM10 and PM2.5 elemental measurements (Cooper Xact 625i).
Ten factors were identified at the site, including commonly detected biomass burning, traffic, nitrate- and sulfate-rich, aged sea salt and mineral dust. With the added additional organic traces, primary biogenic and secondary oxidation were recognized as well. In addition, two unusual factors were disclosed, contributing 10% to annual PM10. Namely, Cl-rich and a mineral dust-rich factor, which we name the cement kiln factor. We associate these two factors to different processes in the cement plant.
The outputs of the study provide vital information about the influence of cement production on PM10 concentrations in complex environments and are useful for PM control strategies and actions.

4. Inhibition strategies of Listeria monocytogenes biofilms- Current knowledge and future outlooks.Sandra Oloketuyi, Fazlurrahman Khanna, 2017, pregledni znanstveni članek Opis: There is an increasing trend in the food industry on the Listeria monocytogenes biofilm formation and inhibition. This is attributed to its easy survival on contact surfaces, resistance to disinfectants or antibiotics and growth under the stringent condition used for food processing and preservation thereby leading to food contamination products by direct or indirect exposure. Though, there is a lack of conclusive evidences about the mechanism of biofilm formation, in this review, the concept of biofilm formation and various chemical, physical, and green technology approaches to prevent or control the biofilm formed is discussed. State-of-the-art approaches ranging from the application of natural to synthetic molecules with high effectiveness and non-toxicity targeted at the different steps of biofilm formation could positively influence the biofilm inhibition in the future.

6. Béla Balázs and the Haunting of Weimar FilmEszter Polonyi, vabljeno predavanje na konferenci brez natisa Opis: We can all list the name of film actresses and film directors. Few of us will remember the name of a scenarist. And yet, the sce- narist might be responsible for every cut of every shot of every scene of a film. This talk is about the Weimar-era Béla Balázs, arguably the world’s most misunderstood film scenarist. In high demand for his world renowned theoretical understanding of the image, Balázs nevertheless is almost entirely unknown for his work in the film studio. Drawing on actual films by Balázs I have retrieved from archives, this talk hopes to recover not just the travails of the scenarist, but the aspects of the film image that he or she haunts.

9. MAST CHALLENGE LAB DISCUSSIONJurij V. Krpan, Peter Purg, Sergi Badia, di, Simon Mokorel, druga izvedena dela Opis: The Challenge Lab discussion delved into the concept of the Situation Room – a setting within which an interdisciplinary group, interested in taking part in an innovation process is put in front of a challenge – to provide a technological innovation, an application of a technological innovation in the society, or a social innovation. Such process is to be facilitated by an “innovation catalyst”, a professional profile which is being built through AST study modules, such as MAST. The discussion gives a deeper insight of the terms such as: challenge lab, innovation catalyst, and art thinking.
