New approaches in calibration for multielement laser ablation inductively coupled plasma mass spectrometry analysis
One of commonly used analytical technique for direct elemental analysis of solid samples is Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Although widely used for the analysis of various samples, obtaining accurate quantitative results remains a major challenge as matrix-matched standards are required. The aim of this thesis was …
Neural approaches to automatic terminology extraction
Automatic terminology extraction, also known as automatic term extraction (ATE), is a natural language processing (NLP) task that identifies specialized terminology from domain-specific corpora. ATE is often used for terminographic tasks (e.g., the creation of specialized dictionaries) and contributes to several complex downstream tasks (e.g., machine translation and information retrieval). …
Tracing origin of food using stable isotopes of light and heavier elements
This dissertation examines two main topics. The first topic is focused on the potential of strontium (Sr) isotope analysis to characterise milk and truffles as selected food commodities, traditionally important for Slovenia. The 87Sr/86Sr ratio for determining the provenance of bovine milk and truffles originating from different regions of Slovenia …
Deposition and protection mechanisms of zirconium conversion coatings on aluminium alloy, steel and zinc substrates
This thesis focuses on the development and optimisation of zirconium conversion coatings (ZrCCs) on cold-rolled steel (CRS), zinc (Zn), and aluminium alloy AA5754 substrates through a multidimensional approach. The utilization of statistical tools, specifically response surface methodology (RSM), enabled the assessment of the individual and mutual effects of various parameters …
Assessment of dimethyl sulphide odorous emissions released during the underground coal extraction in coal mine Velenje
Underground coal extraction at Coal Mine Velenje occasionally gives rise to odour complaints from local residents and irritates and disturbs the miners at work in the mine. This work describes a robust quantification of odorous emissions of mine sources and a model-based analysis aimed to establish a better understanding of …
Tracing mercury in the wider Idrija region using stable isotopes
Mercury, a toxic element, known for its physical and chemical properties, spreads throughout the environment and is found in various ecosystems, including water, air, soil, and biological systems. The natural mercury cycle begins beneath the earth's crust, where it rises to the surface and is released into the air through …
Spatial and energy distributions of sputtered atoms in thin film deposition techniques
The sputtering yield, the spatial distribution of the sputtered atoms, the energy distribution and the average energy of the sputtered atoms are important for numerous deposition techniques, as they determine the microstructure and the physical properties of the thin films. Using SRIM (Stopping and Range of Ions in Matter) simulations, …
Computational investigation of protein-RNA interactions detected by CLIP, their specificity and dynamics in embryonic development
RNA molecules dynamically interact with RNA-binding proteins (RBPs), which control various aspects of RNA fate, such as its processing, localisation, and stability. Intricate networks of protein-RNA interactions thereby regulate gene expression and have a profound effect on downstream cellular processes. Most RBPs recognise specific motifs on their bound RNAs, characterised …
Information spreading barriers in news
News spreads in many patterns, structures, and dynamics that change throughout time. For a variety of reasons, certain news is only covered in a particular area. Language, economy, geography, politics, time zone, and culture are just a few of the many barriers that prevent news from reaching a larger audience. …
Heterogeneous recombination of neutral oxygen atoms on the surfaces of oxidized materials
In this dissertation, we studied heterogeneous surface recombination of neutral oxygen atoms. We described plasma as a reliable source of neutral oxygen atoms and the behavior of neutral atoms in low-pressure plasma sustained by high-frequency discharges. Neutral atom density in the flowing afterglow and the recombination coefficient on several surfaces …
