1. Energy demand distribution and environmental impact assessment of chitosan production from shrimp shellsFilipa A. Vicente, Robert Hren, Uroš Novak, Lidija Čuček, Blaž Likozar, Annamaria Vujanović, 2024, izvirni znanstveni članek Opis: Step towards resilience and sustainability through exploring renewable biomass and waste streams to produce higher-added value products and energy is among key aspects for closing the loops, saving resources, and reducing the resource and emission footprints. In that respective, crustacean shells waste can offer rich spectre of valuable compounds such as proteins, chitin, carotenoids. This waste is produced in large quantities worldwide, thus allowing for commercial valorisation. An overview of technologies is undertaken for more sustainable and environmentally friendly chitosan production via chitin isolation and conversion and compared to the conventional processes. Furthermore, an assessment of the environmental burden and energy demand distribution for conventional and more sustainable alternative processes was performed, based on lab-scale experimental data. Three different chitin extraction routes and three distinct chitosan conversion processes were considered and compared for their greenhouse gas footprint, abiotic depletion, acidification, eutrophication and other potentials. Finally, the energy demand distribution was analysed considering electricity production patterns from three European countries, Slovenia, Portugal and Norway. The results showed that alternatives 3-A and 3-B (conventional eco-solvents - conventional deacetylation with 40 % and 50 % NaOH) generate the lowest environmental burden (184 g CO2 eq./g chitosan). Electricity was the main hotspot of the processes, used either for extraction, plasma treatment or deacetylation. The sensitivity analysis proved that the Norwegian electricity mix has the lowest environmental impact (4.2 g CO2 eq./g chitosan). This study highlights the impact of blue biorefineries by transforming marine waste to valuable biopolymers such as chitin and chitosan.

4. Comparative genomics of Sulfurimonas strains with focus on Sulphur oxidationAna Rojko, 2022, magistrsko delo Opis: Introduction: Several Sulfurimonas species have been isolated from sulfidic marine habitats over the years. In addition, many 16S rRNA sequences related to Sulfurimonas strains were identified in chemically distinct environments. The two recently discovered strains S. marisnigri SOZ1T and S. baltica GD2T were investigated in detail in the context of this master thesis. S. marisnigri SOZ1T was sampled in 2013 from the Black Sea at the lower boundary of the suboxic zone where hydrogen sulfide (H2S) was just above the detection limit. S. baltica GD2T was isolated in 2016 from the Baltic Sea at a depth of 225 m where anoxic but, not sulfidic waters were present.
Methods: Quantitative methodology was used to show gene abundances in the sulfur cycle and sqr distribution. All the necessary data were analyzed with different bioinformatics tools, mainly Prokka, Diamond, MAFFT, FastTree, ITOL, EDGAR, R/Complex-Heatmap and represented by tables and figures.
Results: Based on phylogeny, pangenome analysis and sox cluster comparisons, it was confirmed that S. baltica GD2T and S. marisnigri SOZ1T are closely related, they both share the same set of sox genes and phylogenetically similar sox clusters.
Discussion and conclusion: Within this research and all the analysis that were performed no major differences between S. baltica GD2T and S. marisnigri SOZ1T compared with other Sulfurimonas strains were detected. It is possible that niche differentiation between these two organisms is conducted by unknown genes, however more in-depth analysis is required to elucidate the differences between these organisms. Furthermore, it is necessary to perform expression analysis in addition to genomic analysis to figure out which genes are active and under which conditions.

5. Rhetorical Figures Between Traditional Poetry and RapRok Klemenčič, 2020, magistrsko delo Opis: This Master’s thesis looks into figures of speech used in classical poetry as compared to rap. With the help of Heinrich F. Plett’s analytic scheme, we have established a model for future linguistic comparison which could be modified and applied to various fields and works. The results of the analysis have shown similarities and differences between poetry and rap from the point of view of figures as well as other rhetorical devices: rhythm, structure, motifs, etc. The figures are identified and their potential influence on the perception of the poem/rap song is analysed. Stylistic analysis serves as a basis for the comparison, and the thematically connected pairs allow us a deeper insight into the selected works. Some similarities beyond the mere use of figures are established, i.e., motifs, themes, rhythm and meter. This analysis allows us to compare the genres, while the results show tendencies and characteristics typical of either traditional poetry or rap, i.e., use of certain rhymes, orthography, and punctuation.

6. Trial by jury in Russia : from the cornerstone of the judicial reform to the constitutional history artifactAnna Gurinskaya, 2015, izvirni znanstveni članek Opis: Purpose:
The article explores the process of gradual legislative encroachment on the constitutional right to be tried by jury in Russia that had started in 2008 when offenders accused of committing terrorist crimes were denied the right to opt for the jury. The objective is to show how the initial use of the security argument made possible further limitations of this right.
Design/Methods/Approach:
The research is based upon qualitative analysis of documents (drafts of legal bills, explanatory notes to the drafts, minutes of the Parliamentary hearings), decisions of the Constitutional Court of the Russian Federation and judges’ dissenting opinions, statements of public officials, media reports.
Findings:
Jury trial that was once a cornerstone of the major judicial reform of the 1990-ies risks becoming a constitutional history artifact. The process of its curtailment came as a result of the inability of this institute to get adjusted to the realities of the Russian criminal process as well as of the need of the state to meet the challenges of the risk society. It is argued that the use of security argument allowed for the initial bill aimed at limiting this right for terrorists to be adopted swiftly and without much debate. It also opened the window of opportunity for further limitation of this right that came under vague agenda of victims’ protection and case review system reform. The author demonstrates that decisions of the Constitutional Court of Russia have played a significant role in promoting limitations of jury trials.
Practical Implications:
The approach used in the article can be applied to researching other cases of limiting citizens’ rights in the name of security.
Originality/Value:
The article represents an attempt to provide empirical evidence of the ‘security paradoxes’ described in the security literature.

7. Nationality diversity of bank boardsMiroslav Nedelchev, 2018, izvirni znanstveni članek Opis: The aim of this paper is to carry out a comparative study for nationality diversity in bank boards. The study covers practices of board diversity of nine commercial banks. The data are compared for subsidiary banks in Bulgaria and their parent banks from the home country. The study defines a high degree of nationality diversity in subsidiary banks. The Bulgarian banks have a higher number of foreign members on boards compared to their parent banks. The good practices on board diversity in Bulgarian banks are a consequence of their subordination in European financial conglomerates and are aimed to reduce agent conflicts.

8. Minority writing: the case of Friuli-Venezia Giulia (Italy), Goriška and Coastal-Karst regions (Slovenia)Ana Toroš, 2017, izvirni znanstveni članek Opis: The paper discusses the literature of national and linguistic minorities along the Slovene-Italian border area (Slovene and Friulian literature in Italy, Italian literature in Slovene Istria), comprised of the Friuli-Venezia Giulia region in Italy, and the Goriška and Coastal-Karst regions in neighbouring Slovenia. The paper claims that a new methodological approach is needed to study these literatures, namely one that will upgrade previous research (studying the literature’s regional specifics which stem from the authors’ common living environment, regardless of their linguistic and national identity, and the depiction of foreign culture in minority literature) and move towards regional comparative literature. Results of such studies would be useful to bolster the teaching materials in literature classes in the area concerned.

10. Mirror image properties in human languagesIreneusz Kida, 2009, izvirni znanstveni članek Opis: In this paper I discuss the phenomenon of mirror image properties in human languages. I give examples from English, Polish, Malay, Gothic, Latin and Classical Greek. Although I take into consideration only a few languages, my paper has further implications, namely, that mirror image properties exist in any language of the world. I start with a description of the natural phenomenon of mirror image and then extend my discussion to language. I talk about mirror image sentences, reduplication, and palindromes.
