Transparent titania-zirconia thin films for self-cleaning and photocatalytic application
Vlasta Brezová, Kandalam Ramanujachary, Nives Vodišek, Urška Lavrenčič Štangar, 2016, objavljeni povzetek znanstvenega prispevka na konferenci

Opis: Thin films were prepared by sol-gel process, where different amount of zirconia were added to titania. Photocatalytic activity of thin films was measured by two methods i) determination of degradation ration of methyl stearate with measuring the contact angle and ii) formation of hydroxyterephthalic acid was measured by spectrofluorometer. Prepared samples were characterized by UV-Vis spectrophotometer, SEM, XRD, FT-IR ATR, and BET. The result of measurements of photocatalytic activity shows that the highest activity has a sample without addition of zirconia, but mechanical stability of that sample is worse.

Condensations and Extensions
Aleš Vaupotič, Narvika Bovcon, 2017, objavljeni povzetek znanstvenega prispevka na konferenci

Opis: Every reading of a text follows a complex mechanism, which is outlined in phenomenological terms in Roman Ingarden's Das literarische Kunstwerk (1930) and later in reader-response criticism. Also Roland Barthes's explorations of intertextuality point in a similar direction of the text as heterogeneous and open texture. The complex mechanisms that allow the reader to gain meanings and construct represented objects etc. are scrutinized to emphasize the importance of the reader's collaboration in the readerly act and the transformations to the textual experience that depend on historical circumstances, on cultural and personal experience of the reader. Considering these critical traditions, any text is always interactive, an ad hoc construct, it comes to life only in contact with alien contexts whereby it virtually looses its supposed lasting identity. In Theorising the Digital Scholarly Edition (Literature Compass 7.2, 2010) Hans Walter Gabler attempts to provide a conceptual framework for a critical scholarly edition, a text genre which is supposed to preserve the original documents and the texts and/or works. However, Gabler rejects the ideology of preservation of memory in the »pure« form and argues for a relational and contextual idea of edition as a »knowledge site«. In addition, he states that the digital medium and the print medium can coexist since they serve different purposes, the printed edition is used for reading and the digital one for »use« and study purposes. The so-called old scholarly editions (pre-positivist) had a strong emphasis on the commentary, which added to the authorial function of the editor as the mediator between the vast textual archive and the receptive abilities of the addressee. Text-edition as a dynamic and collaborative »knowledge site« is sometimes introduced by the characteristics of a particular text. Dora García's art project and video installation The Joycean Society (2013) documents with a video (53 min.) and by exhibiting artefacts the reading process of the mysterious Finnegan's Wake (1939) by James Joyce, the multiple readings within a single heterogeneous reading group of the same book for 30 years. The second case study is the artist's book by a Slovenian net.artist Teo Spiller Znakovnost novih medijev (Semiotics of New Media, 2011). The printed illustrated pages are intended to be read in parallel with browsing the online versions of the art projects presented. Another key dimension of such book-projects is the swift change and disappearance of the on-line part of this plural reading-interface. The third example considered are the projects by Jaka Želaznikar, a Slovene digital poet, that relate to the works of one of the main Slovenian poets Tomaž Šalamun (1941-2014). Among them Železnikar's on-line project Izbris Šalamun (Deletion Šalamun, 2015), which is an on-line edition of two poetry books by Šalamun, Letni čas (Season, 2010) and Ta, ki dviga tačko, spi (The one, who rises the paw, sleeps, 2015), enables the reader to selectively delete the words from poems. The text will examine the reader's reception of the poems in the printed version and in the on-line interface. In this case, too, the context of the edition will be considered (the link with the publishing house and the printed edition, the role in promotion activities of the on-line edition in respect to the printed one).

THE IMPACT OF EUROPEANISATION ON THE NATURE PROTECTION SYSTEM OF SELECTED COUNTRIES OF SOUTHEAST EUROPE ON THE EXAMPLE OF THE ESTABLISHMENT OF MULTI-LEVEL GOVERNANCE SYSTEM OF NATURA 2000
Aleksandar Šobot, 2017, doktorska disertacija

Opis: The Europeanisation of Southeastern Europe led to the pre-accession and accession process of joining countries of the former Yugoslavia to the European Union. Slovenia's accession to the formal process of accession to the European Union started in 1999. This process lasted until 2003. Then, in 2004, Slovenia joined the European Union. Croatia's access to the formal process of accession to the European Union started in 2003. This process lasted until 2012. Then, in 2013, Croatia joined the European Union. Bosnia and Herzegovina entered the pre-accession process with the process of stabilization and association with the European Union, which lasted from 1999 to 2015. Then, in 2016, Bosnia and Herzegovina officially submitted its application for European Union membership. This paper examines the impact of the Europeanisation during this period on the nature protection system in the case of Slovenia, Croatia and Bosnia and Herzegovina while establishing multi-level governance system of protected areas within NATURA 2000 network. The analysis of the establishment of multi-level governance system is performed according to the morphogenetic model in three cycles as a case study. The case study is organized with the help of interviews and desk analysis of the relevant documents. In the first cycle were explained the projects/process of implementation of NATURA 2000 in Slovenia, Croatia and Bosnia and Herzegovina and its changing impacts on national legislation in the area of nature protection (environmental policy). The second cycle explains the role of the main actors in the establishment of multi-level governance system of NATURA 2000 such as the European Union institutions, competent ministries, national parks and non-governmental organisations (environmental polity). The third cycle outlines the contribution to the establishment of multi-level governance system of NATURA 2000 on the nature protection systems of Slovenia, Croatia and Bosnia and Herzegovina and their future challenges (environmental politics). The main conclusions point to the major changes in the nature protection systems of Slovenia, Croatia and Bosnia and Herzegovina during the process of implementation/establishing multi-level governance system of NATURA 2000. Main legal and institutional points of implementation of NATURA 2000 with all positive and negative sides are presented here. In the end, implementation of the European ecological network NATURA 2000 in Slovenia is marked as an excellent example with significant changes in legal (laws on nature protection) and institutional (transformation of governmental institutions, establishment of new institutions and inclusion of NGOs in decision making) framework. This process in Croatia was marked as good with significant changes in legal (laws on nature protection, adopting new strategy of sustainable development) and institutional (transformation of governmental organisation, establishment of new institutions and inclusion of NGOs in decision making) framework. This process in Bosnia and Herzegovina was marked as satisfactory with significant changes in legal (adopting new entity laws on nature protection) and institutional (adopting coordination mechanism for inter-entity and inter-institutional cooperation as well as inclusion of NGOs in decision making) framework. There are also significant weak points during the process of N2000 in all three countries (such as the late change of national legislative, not following the national legislative from governmental institution and not including NGOs into decision making), which during the proces of implementation of N2000 (for Croatia and Slovenia) or the process of preparation of implementation (for Bosnia and Herzegovina) cause significant problems, that call for action in the future in order to improve governance of natural resources /NATURA 2000. On the other hand, these points could serve as an example for all countries that underwent/or should undergo ...

Search for Physics beyond the Standard Model with the CRESST Experiment
2017, magistrsko delo

Opis: In spite of the successes of observational astro- and particle physics and cosmology very much of the universe remains unknown. The Standard Model of particle physics is a theory describing the electromagnetic, weak, and strong nuclear interactions, as well as classifying all the subatomic particles known. But there is overwhelming evidence, that all the known particles, the ordinary (baryonic) matter, the building blocks of planets, stars and ourselves, only make up about 4.9% of the energy content of the universe. The standard model of cosmology (CDM) indicates that the total mass-energy of the universe contains beside the 4.9% ordinary matter two other components: 26.8% dark matter and 68.3% dark energy. The accelerating expansion of the Universe is the result of the effect of the dark energy with its most simple form given by a cosmological constant in Einstein's Equation. Dark matter is an unidentified type of matter that is not accounted for by dark energy and neutrinos and is generally believed to be a non-relativistic, charge neutral and non-baryonic new form of matter. Although dark matter has not been directly observed yet, its existence and properties are inferred from its gravitational effects such as the motions of visible matter, gravitational lensing, its influence on the universe's large-scale structure, and its effects in the cosmic microwave background. Thus the search for Dark Matter is the search for physics beyond the standard model. Although the nature of dark matter is yet unknown, its presence is crucial to understanding the future of the universe. The CRESST experiment is searching for direct evidence in the form of a nuclear recoil induced on a scintillating CaWO4 crystal by a dark matter particle, and is installed and taking data underground at Laboratory Nazionali del Gran Sasso (LNGS) in Italy. While both, dark energy and dark matter, have not been detected directly, a class of dark matter particles that interact only via gravity and the weak force, referred to asWeakly Interacting Massive Particles (WIMPs), has been established as the leading candidate among the dark matter community. For this thesis a special model of dark matter was studied, namely the dark photon. This thesis provides a detailed description of the calculation of the 90% upper limit on the dark photon kinetic mixing based on data from the second phase of the CRESST experiment. The analysis was carried out in a frequentist approach based on the (unbinned) maximum-likelihood method and likelihood ratios. To make a statement about the calculated result and its quality, the used algorithm had to be tested, what was done with Monte Carlo simulations (pseudo data).

The Resiege of Neptun
Peter Purg, 2017, umetniško delo

Opis: After the Neptun Trilogy (2011-13) and its Re:enactment in 2014 (vimeo.com/119334124), the performer returns to the site -- now taken over by yet another corporation: The ex-Neptun factory in Komiža, island of Vis (Croatia) was being used as one of the strictly closed areas on the island for shooting of the Hollywood blockbuster Mamma Mia 2. Since the production of part one left a small idyllic Greek island had bereft of peace and well-being, the islanders accepted it with much ambivalence. Thus Neptun's pier had to be sieged again, even if only at its floating tip, the plastic pontoon (02:25 - 02:45 ).

The detection and study of biologically active compounds in environmental processes and samples
Mojca Žorž Furlan, doktorska disertacija

Opis: Environmental pollution in the 21th century still represents a global problem for human and animal health. Despite general awareness about released substances and their degradation products their fate and possibilities of removal are not well investigated. Even though the chemicals released are dispersed and diluted in water cycles, their poor biodegradability and/or strong accumulation can result in the intoxication of exposed organisms. Similarly, as a part of the environment, food can get contaminated by bioactive substances during different steps of preparation. Not only artificial compounds such as pesticides or pharmaceuticals, but also natural toxins enter the food chain and impact negatively on humans' and animals' health. In addition, the activity of some bacteria can influence the production of amines from amino acids after fermentation, to which the human body responds with several symptoms of intoxication. Several analytical methods for the determination of trace levels of broad range contaminants have been developed. Due to the largely robust, selective and sensitive features of the conventional (rearguard) techniques, they represent the first choice for analysing multiple organic compounds in frequently very complex matrices. However, screening (vanguard) methods are paving the way in the chemical analytics as a solution that provides simplicity and rapid analytical responses with binary (yes/no) answers. They require little or no sample treatment as well as more economically-efficient instrumentation. The combination of vanguard-rearguard analytical strategies hence offers a compromise between classical analytical figures of merit and productivity-related characteristics. In the first part of our research feasibility studies for the application of TLS and/or TLM in novel analytical methods for the determination of lipid-lowering drug atorvastatin and a mycotoxin ochratoxin A . The survey on atorvastatin performed spectrophotometrically has shown a decrease of ATV-sulpho-vanillin product at the wavelength of its maximum absorbance after dilution by organic solvent, which was investigated due to the possible increasing of the method sensitivity. As the predicted LODs that could be obtained by TLM (0.3 mg/L) could not reach the concentration of ATV usually present in the environment (ng/L-g/L) further experiments on this subject were therefore not justified. On the other hand, the ELISA assay for the determination of ochratoxin A was performed. In case of μFIA-TLM, the measurements were influenced by high background signal resulting in high LODs of TLM (470 pg/mL), which is known as a background limited technique. It was estimated that the LODs of standard ELISA assay could not be significantly improved, therefore no further research was conducted in this direction. In the second part of the dissertation, a sensitive rearguard system by coupling HPLC and TLS for the determination of biogenic amines in wine samples was developed. Putrescine, cadaverine, histamine and tyramine were separated and detected on a HPLC-TLS system after derivatization by dabsyl chloride. The method was optimized in terms of chromatographic conditions and in terms of TLS parameters. Also, the sensitivity of the newly developed method was evaluated by comparing the TLS detection with DAD detection in terms of LOD values, where TLS showed 3.6-fold improvement compared to DAD. Afterwards, the standard addition calibration was performed and evaluated for its recoveries (86−117%) in the determination of the four BAs. The applicability of the novel method was tested by the analysis of real white and red wine samples and by comparing the results to the standard HPLC-FL method and concentrations of BAs in wine samples were in good accordance. In addition, the dabsylated BAs showed better stability compared to the OPA derivatives as they have not lost the peak intensity after 17h of storage. In the third part, a vanguard system for detection of the overall biogenic amines concentration was developed by employing μFIA-TLM. Initially, NH4Cl standard solutions were applied in the indophenol reaction for batch mode, off-line μFIA-TLM and in an on-line indophenol formation for μFIA-TLM detection. By adding 50 % of EtOH to indophenol we obtained 9-fold improvement. In addition, indophenol showed good stability under TLM conditions. We optimized the microfluidic and TLM parameters in the off-line and on-line indophenol reaction. The addition of 5% ethanol to the reagent in the on-line reaction resulted in the 3-fold improvement of the signal-to-noise ratio. Further on, the overall reaction, including the enzymatic and the following indophenol reaction, was optimized by choosing the optimal buffer (pH=7, 0.5 M) and alkaline conditions (2M NaOH). The influence of interferences from amino compounds was also evaluated and discussed. The off-line and on-line μFIA-TLM were evaluated by their performance characteristics. The LOD for ammonia detection reached 2.3 μM and the applicability in ammonia detection in water samples was discussed. Similar LOD of 3.2 μM was obtained for the overall concentration of BAs and LOD of 3.8 μM for histamine, which is more than 4-folds lower value as the lowest suggested limits of intake for histamine in wine samples (2 mg/L; 18 μM). Finally, an immobilization procedure on magnetic nanoparticles was developed for the possible implementation of the selected enzyme in a miniaturized biosensor.

ACCESSIBILITY AS A NON-PREJUDICIAL APPROACH: IS CULTURE BACK TO NORMALITY?
Ilaria Bollati, 2018, doktorska disertacija

Opis: This research explores the general and actual accessibility to cultural spaces and organizations, focusing on the network of relationships between contents, innovation, and participation. It investigates how Culture can be perceived as a normal experience, actually able to set a rich dialogue with each of us, normal ordinary people/consumers. Normality means inclusion and sharing. The proposed investigation is based on a triad of interactions among culture, economics, and design. Assuming that Culture generates its value from a cognitive approach, or from a dynamic and context-dependent value chain that is subject to a cognitive evolution, this research acknowledges that the cultural experience is subject to a double issue of access: - The horizontal question is related to complications associated with the structure. Believing that ‘culture is special’ implies the risk of progressively widening the gap between cultural supply and society. Culture is ‘locked’ in specific sites and a big slice of the world’s adult population has yet to be involved in any cultural experience. - Once physically inside the cultural structure, the vertical issue is generated by the difficulty in entering in contact with the offered contents. This research focuses only on museums and multimedia exhibitions in which the learning process has changed: the research presents itself as a conversation where both ‘those who know’ and ‘those who learn’ play equally active parts in a relative process of understanding. Starting from the existing processes, forms, previous studies and case studies, the survey yearns for their systematization in innovative models. The process, from theory to practice and vice versa, goes beyond a traditional mechanism of deduction: it moves from specific contexts to the abstraction of replicable approaches. The question of how the narration emerges guides you toward a new method of analysis, study, and cataloguing; a schematization capable of investigating not only knowledge, but also the visitor's ‘cognitive metabolism’ (how knowledge is acquired) during the multimedia experience; an innovative multipurpose tool, useful for both the museum institution and the designer. The research finally assesses and takes into account an actual experiment, the outcomes of which may prove to be useful in feeding theoretical implications with empirical experiences: RovelloDue - Piccolo Spazio Politecnico, a temporary multimedia space.

Transmedia Adaptation
Narvika Bovcon, Aleš Vaupotič, 2018, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: This essay is composed of two parts. The first chapter reflects on the genesis of film language, and in this context, considers the reception of Dickens’ works. Next the text turns to borderline cases of adaptation: genre/media hybrid, deep remixability, and allusion. The notions of genre and media are considered as only quantitatively different, not qualitatively, both instances of discourses and apparatuses considered by the theory of discourse (Bakhtin, Foucault etc.). The second part of the text presents an artistic inquiry—concepts and ideas used in production of artworks by the authors of this essay—that sheds light on the possible methods of studying adaptations. Two aspects are foregrounded: the ideas of the transformation of the source text into an archive of fragments that are subsequently put in new meaningful constellations, and the use of Shakespeare’s works in the role of a mediator in the understanding of the language of new media art.
