41. KINETICS OF CELLULOSE DEGRADATION STUDIED USING SIZE EXCLUSION CHROMATOGRAPHYAneta Balažic Fabjan, 2016, master's thesis Abstract: For more than five centuries, paper has been the predominant carrier of information and numerous medieval manuscripts bear witness of its durability. However, increasing demand for paper led to several changes in its production in the 19th century. High quality rag fibres were replaced by inferior wood-originating ones. Acid manufacturing technology was introduced which, due to its simplicity and low cost, continued to be used until the end of the 20th century. Inherently stable paper rapidly degrades in the presence of acids and its decay is further promoted by the poor storage conditions and environmental pollutants. As a result, the amount of degraded paper in libraries, archives and museums is reaching enormous proportions. In order to prolong the usable time of the vast quantities of original materials, paper collections may be deacidified and/or stored at lower temperatures. While preservation options are known, lack of the competent comparative studies leaves collection keepers hesitant of their use. The introductory part of the project is focused on development of analytical methodologies and model materials, representative of historical acid paper. As uniqueness and inherent value of cellulose-based cultural heritage limits the use of analytical methodologies to the non-destructive or micro-destructive ones. A new methodology for determination of the condition of paper was developed. The analytical technique-size exclusion chromatography for the first time allows us to reproducible determine the condition of paper which contains a significant amount of wood derived lignin. A few fibres suffice for the analysis, which renders the methodology suitable for characterisation of historical materials. The results of the research will represent the effect of deacidification processes with use of micro destructive analytical methodologies. As written word is all what we have for our legacy from generation to generation, evaluating preservation strategies for decaying collections, safekeeping and long term access to the endangered written cultural heritage is one of the most important facts.

42. Conjunct Agreement and Gender in South Slavic: From Theory to Experiments to TheoryJana Willer Gold, Franc Marušič, Tina Šuligoj, 2016, original scientific article Abstract: Agreement with coordinated subjects in Slavic languages has recently seen a rapid increase in theoretical and experimental approaches, contributing to a wider theoretical discussion on the locus of agreement in grammar (cf. Marušič, Nevins, and Saksida 2007; Bošković 2009; Marušič, Nevins, and Badecker 2015). This paper revisits the theoretical predictions proposed for conjunction agreement in a group of South Slavic languages, with a special focus on gender agreement. The paper is based on two experiments involving speakers of Bosnian/Croatian/Serbian (BCS) and Slovenian (Sln). Experiment 1 is an elicited production experiment investigating preverbal-conjunct agreement, while Experiment 2 investigates postverbal-conjunct agreement. The data provide experimental evidence discriminating between syntax proper and distributed-agreement models in terms of their ability to account for preverbal highest-conjunct agreement and present a theoretical mechanism for the distinction between default agreement (which has a fixed number and gender, independent of the value of each conjunct) and resolved agreement (which computes number and gender based on the values of each conjunct and must resolve potential conflicts). Focusing on the variability in the gender-agreement ratio across nine combinations, the experimental results for BCS and Sln morphosyntax challenge the notion of gender markedness that is generally posited for South Slavic languages.

44. Stare sadne sorte na Goriškem 1-2Zoran Božič, Gregor Božič, Jana Kocjan, 2013, professional monograph Abstract: Prvi del publikacije po uvodu, ki poudarja pomen ohranjanja in širjenja starih sadnih sort (Goriška je bila v času Avstro-Ogrske sadjarski raj imperija), prinaša intrevju z Brunom Podveršičem, pionirjem tovrstnega raziskovanja. Po predstavitvi švicarske organizacije Pro Specie Rara sledi opis zgodnjih in poletnih sort: češenj, marelic, hrušk, breskev in drena.

48. Can agreement with the linearly closest conjunct be derived in syntax proper?Franc Marušič, Jana Willer Gold, Boban Arsenijević, Andrew Nevins, 2015, published scientific conference contribution abstract Abstract: The recent literature on South Slavic conjunct agreement can be roughly divided into two camps: those trying to model the cases of agreement with linearly closest conjunct, as in the Bosnian/Croatian/Serbian (BCS) example in (1) (taken from Bošković 2009), within syntax (Bošković 2009, Puškar & Murphy 2015 a.o.) and those claiming this agreement is a result of a postsyntactic operation that occurs after linearization and hence is sensitive to the linear distance between two syntactic elements (among these, Bhatt & Walkow 2013, Marušič et al 2015). We present a strong argument against strictly syntactic theories of conjunct agreement that leverages experimental work on BCS conjunct agreement and builds on data in Aljović & Begović (2015).

49. High-resolution X-ray absorption spectrometry of atomic vaporsIztok Arčon, Jana Padežnik Gomilšek, Alojz Kodre, Andrej Mihelič, 2004, original scientific article Abstract: A measurement of an x-ray absorption spectrum of a monatomic sample yields pure atomic absorption essential for the EXAFS (Extended X-ray Absorption FineStructure) analysis in cases of a weak structural signal. A construction of an absorption cell to contain vapor sample takes into account specific properties of the investigated element. Metal-vapor absorption cells for the elements K, zn, Rb, Cd, Cs, and Hg are presented and comments are made on the use of materials and the operating mechanisms of the cells.

50. X-ray absorption spectroscopy and related techniquesIztok Arčon, Alojz Kodre, Jana Padežnik Gomilšek, 2004, original scientific article Abstract: In the extensive field of X-ray diagnostic techniques, nowadays mostly implemented on synchrotron X-ray sources, the X-ray absorption methods offer a relatively simple tool for structural analysis of materials. The advantage of the methods is the sensitivity to chemical species and the insensitivity to the long-range order. An overview of various detection techniques is given together with the discussion of accuracy of the method with regard to the spatial resolution and the possible contamination by intra-atomic contributions, the multielectron photoexcitations.
