311. // Crypto-Minding: postindustrijski podatkovni aktivizem : PostMobilnost; GO!2025 Evropska prestolnica kultureMarina Zafiris, Christopher Csikszentmihalyi, razstava Opis: // Stoletje obsedene industrializacije nam je širom zemeljske oble zapustilo obilico poceni energije, zemljišč in infrastrukture. Naraščajoči val »kripto-podjetnikov« spreminja odpisane industrijske prostore v objekte za »kripto rudarjenje«, neskončne algoritme poganjajo fosilna goriva in pri tem ustvarjajo vprašljivo vrednost. Razstava prikaže različne računalniške tehnike za sodelovanje in skrb v prizadeti skupnosti ter okolici elektrarne Greenidge Bitcoin Mining na jezeru Seneca v zvezni državi New York, ZDA. Predstavljene bodo umetniško-aktivistične intervencije v javno mnenje in taktike protinadzora, ter problematika toplotnega onesnaževanja voda. Gre za preizpraševanje proizvodnje javno dostopnega znanja in soustvarjanje računalniško podprtih orodjarn za radikalno družbeno organiziranje in politično komunikacijo. / Ob otvoritvi razstave postrežemo s pašteto soške postrvi spodnjega toka.

313. Ivo Andrić in Slovenke : predavanje na Petnajstem, jubilejnem simpoziju: Andrićeva publicistika, Ljubljana, Maribor, Bled, 19.-22. oktober 2023Darko Ilin, 2023, prispevek na konferenci brez natisa Opis: Cilj tega prispevka je raziskati delo Iva Andrića in njegovo povezanost s pojmom slovenske ženske. V prvem delu članka bom predstavil Andrićevo dojemanje Slovenk, podano v knjigi Znamenja ob poti. Njegove opise slovenske ženske skušam analizirati z vidika študijev spolov in ženskih podob ter si prizadevam ugotoviti pomen izpostavljenih značilnosti Andrićevih Slovenk. Drugi del članka je posvečen povezanosti Iva Andrića z ženskami slovenskega literarnega sistema. Izpostavil bom nekaj ključnih točk, kot so Andrićev prevod Vide Jeraj v srbohrvaščino, njegovo pismo ob smrti Zofke Kveder, odzive Mire Mihelič in Zlate Vokač na njegovo delo ter navsezadnje prizadevanja sodobnih prevajalk Andrićevega dela v slovenski jezik. Ta pregled po prispeval k boljšemu razumevanju tega, kako je Andrić dojemal Slovenke in hkrati, kako so se Slovenke odzivale na jugoslovanskega nobelovca.
Ključne besede: Ivo Andrić, študije spolov, reprezentacije ženskosti, medkulturni stiki

316. Insights into the size-resolved dust emission from field measurements in the Moroccan SaharaCristina González-Flórez, Martina Klose, Andrés Alastuey, Sylvain Dupont, Jerónimo Escribano, Vicken Etyemezian, Adolfo Gonzalez-Romero, Yue Huang, Konrad Kandler, Jesús Yus-Díez, 2023, izvirni znanstveni članek Opis: Atmospheric mineral dust consists of tiny mineral particles that are emitted by wind erosion from arid regions. Its particle size distribution (PSD) affects its impact on the Earth's system. Nowadays, there is an incomplete understanding of the emitted dust PSD and a lot of debate about its variability. Here, we try to address these issues based on the measurements performed during a wind erosion and dust emission field campaign in the Moroccan Sahara within the framework of FRAGMENT project.

318. Effects of Photodegradation in TLS Measurements: Troubleshooting and Applications in Photochemistry and PhotocatalysisMladen Franko, 2023, objavljeni povzetek znanstvenega prispevka na konferenci (vabljeno predavanje) Opis: Most analytical applications of thermal lens spectrometry (TLS) and related theoretical models consider absorbance of the sample constant during a single excitation by the pump laser beam. For photolabile analytes intensive excitation light can cause photodegradation, which significantly affects the results of TLS measurements.
Theoretical models have been developed to account for changes in concentration and consequent changes in absorbance, caused by chemical reactions of different orders. Furthermore, abnormal TLS signal transients were observed for fast photochemical reactions on millisecond time scale, and the contributions of photodegradation as well as molecular diffusion were analyzed in detail. It has also been demonstrated that such effects can be reduced by performing TLS measurements in flowing systems such as in the case of flow injection analysis (FIA) or microfluidics.
These findings were utilized to study the kinetics of chemical reactions, processes such as photostability of the soybean oil and thermal stability of biodiesel, or to improve the sensitivity of TLS detection in case of photolabile analytes. Furthermore, in combination with the concept of biomolecular recognition, FIA-TLS was exploited to study the efficiency of photocatalytic degradation of some neurotoxic substances such as organophosphate insecticides and revealed the formation of even more toxic degradation products. High sensitivity of TLS has enabled discrimination between photocatalytic and photosensitization mechanisms in photocatalytic degradation of textile dyes as well as between photodegradation and photocatalysis as will be demonstrated by the results of latest research in this field.

319. Recent Progress and Applications of Thermal Lens Spectrometry and Photothermal Beam Deflection Techniques in Chemical Analysis and Materials' CharacterizationMladen Franko, 2023, predavanje na tuji univerzi Opis: Initially the theoretical background relevant to recent developments of thermal lens spectrometry (TLS) which include TLS detection in liquid chromatography and in microfluidic flow injection analysis (μFIA) and to non-contact and non-destructive characterization of composite materials by beam deflection spectrometry (BDS) is presented. The advantages and basic characteristics of the TLS and BDS techniques are illustrated by presenting applications such as the determination of free bilirubin in endothelial cells by HPLC-TLS, studies of diffusion in Taylor-type microfluidic flows by thermal lens microscopy (TLM), μFIA-TLM detection of microcystin-LR and Cr(VI) in waters, and by the dept profiling of multi-layered coatings of orthopaedic implants.
In the main part of the presentation the results of joint MU-UNG research are presented with emphasis on BDS and TLS characterisation of biocomposite materials from cellulose and chitosan or keratin with added Ag nanoparticles, sporopollenin capsules or antibiotics. The focus is on BDS determination of thermal parameters including thermal diffusivity and related properties relevant for medical applications, such as porosity and surface roughness, as well as on the TLS detection of Ag and other nanoparticles applied in studies of nanoparticle leaching from biocomposites.
