When linearity prevails over hierarchy in syntax
Franc Marušič, Tina Šuligoj, 2017, original scientific article

Abstract: Hierarchical structure has been cherished as a grammatical universal. We use experimental methods to show where linear order is also a relevant syntactic relation. An identical methodology and design were used across six research sites on South Slavic languages. Experimental results show that in certain configurations, grammatical production can in fact favor linear order over hierarchical structure. However, these findings are limited to coordinate structures and distinct from the kind of production errors found with comparable configurations such as “attraction” errors. The results demonstrate that agreement morphology may be computed in a series of steps, one of which is partly independent from syntactic hierarchy.
Keywords: experimental syntax, syntactic agreement, elicited language production, coordinated, noun phrases, South Slavic languages

Biogas production from brewery spent grain as a mono-substrate in a two-stage process composed of solid-state anaerobic digestion and granular biomass reactors
Mario Panjicko, Gregor Drago Zupančič, Romana Marinšek-Logar, Lijana Fanedl, Marina Tišma, Bruno Zelić, 2017, original scientific article

Abstract: Anaerobic digestion of brewery spent grain as a mono-substrate was studied. Brewery spent grain is a substrate consisting largely of cellulose, hemicellulose and lignin, which are difficult to degrade anaerobically, mostly due to the presence of degradation products, such as phenolic compounds, which cause process inhibition. Therefore, a two-stage system was used for anaerobic digestion. Anaerobic digestion was phase separated in a solid-state anaerobic digestion reactor, where microbiological hydrolysis and acidogenesis occurred and in a granular biomass reactor where mostly methanogenesis was performed. The overall process exhibited total solids degradation efficiency between 75.9 and 83.0 %. Average specific biogas production was 414±32 L/kg, whereas biomethane production was 224±34 L/kg of added total solids. Granular biomass after adaptation exhibited stable operation at substrate C/N ratios in range 0.16 – 4.68. p-cresol was present in concentrations up to 45 mg/L and during the process was successfully degraded by granular biomass. The excellent adaptability of granular biomass was confirmed by 68.2 % shift in bacterial and a 31.8 % shift in archaeal community structure in a granular biomass reactor. The structure of the bacterial community from granular biomass reactor and solid-state anaerobic digestion reactor remained 79.4 % similar at the end of the experiment, whereas archaeal community was only 31.6 % similar. The process exhibited stable operation for 198 days, which shows that brewery spent grain can be successfully anaerobically digested and used for biogas production.

Anaerobic digestion of brewery spent grain as a mono-substrate in a two-stage anaerobic digestion using solid-state digestion reactor and granulated biomass reactor
Mario Panjicko, Gregor Drago Zupančič, Romana Marinšek Logar, Marina Tišma, Bruno Zelić, 2016, published scientific conference contribution (invited lecture)

Abstract: Anaerobic digestion of brewery spent grain as a mono-substrate was studied. Anaerobic digestion was phase separated in solid state anaerobic digestion reactor, where mostly microbiological hydrolysis and acidogenesis and granular biomass reactor where mostly methanogenesis was performed. The overall process exhibited total solids degradation efficiency between 73.6 and 80.4%. Average specific biogas production was 424±36 L/kg, whereas biomethane production was 230±34 L/kg of brewery spent grain total solids. Granular biomass after adaptation exhibited stabile operation at C-N ratios as low as 0.2 – 0.3, which is rare in anaerobic digestion. P-cresol as a degradation product was present in concentrations up to 45 mg/L and during the process successfully degraded. The excellent adaptability of the granular biomass is confirmed by 67% shift in bacterial and a 32% shift in archaeal community structure in granular biomass reactor after 198 days of successful operation.

EVALUATION OF MARINE SEDIMENTS FROM THE PORT OF LUKA KOPER FROM THE ENVIRONMENTAL PERSPECTIVE AND IN TERMS OF THEIR USABILITY IN THE BRICK INDUSTRY
Patrik Baksa, 2016, master's thesis

Abstract: The majority of the world’s goods are transported over water and dredging is essential for the development of harbors and ports. Therefore, the management of dredged material is a worldwide issue. Due to its chemical and petrographic, mineralogical and homogeneity composition, marine sediments are an appropriate raw material to use in the brick industry. Marine sediments can serve as raw material for the production of clay blocks, roofing and ceramic tiles. Different analyses were carried out in order to determine if the dredged material from the Port of Koper is environmentally friendly and suitable to use in the brick industry. These analyses included: a chemical analysis, a mineralogical analysis, a particle size analysis and a chloride content (Cl-) analysis, and tests of firing in a gradient furnace. Furthermore, tests of mechanical properties, as well as tests of frost-resistance of the samples were carried out. On the basis of primary analyses and samples prepared in a lab, it was established that marine sediments from the Port of Koper without any additives are only conditionally suitable as a source material for producing brick products. In collaboration with Gorica brickworks (Goriške opekarne), a pilot production from a mixture of 60% component B from Gorica brickworks and 40% component A (marine sediments) from the Port of Koper was prepared. Different tests showed the mixture could be appropriate for brick production.
Keywords: marine sediments, recycling, clay bricks, chemical analysis, mechanical properties, brick production.

CHARACTERIZATION OF SLOVENIAN APPLE JUICE WITH RESPECT TO ITS GEOGRAPHICAL ORIGIN AND AGRICULTURAL PRODUCTION PRACTICE
Karmen Bizjak Bat, 2016, doctoral dissertation

Abstract: Determination of food authenticity is an important issue in quality control and food safety. Recent studies predict a growing demand for natural and more authentic food and beverage products. The quality and authenticity of apple juice is also of a great economic importance since the popularity and demand for apple juice consumption has increased. The growth of the market for organically produced apples and apple juice is due to the increasing demand for healthy food requirements, protection of the environment and the promotion of biotic diversity. Organic foods have a higher nutritional and health value, but they are more expensive, because their production is more difficult and less profitable. In addition to how food is produced, consumers are increasingly placing emphasis on food products of specific region, which are known for their unique natural flavours and taste. The presented thesis is based on four separate but closely interrelated studies, in which a combination of different isotopic ratios of bioelements (2H/1H, 13C/12C, 15N/14N, 18O/16O), multi-element analysis, and major primary and secondary metabolite profiles were exploited to differentiate the geographical origin and agricultural production practice (organic vs integrated/conventional) of Slovenian apples. These parameters were used to establish the first database of authentic Slovenian apple juice, which can be used to verify the authenticity of commercially available apple juice in Slovenia. The first preliminary study was entitled “Organic Cultivation ~ Geographical Origin (OCGO)” and was performed using apples from the 2009 growing season. Its aim was to examine the use of stable isotope and multi-element data for determining the geographical origin and agricultural production practice of fresh apple juices. Fruits of six apple (Malus domestica Borkh) cultivars (Topaz, Idared, Golden Delicious, Goldrush, Gala, Gloster) were collected from four different geographical regions of Slovenia (Alpine, Dinaric, Pannonian and Mediterranean) grown under organic and integrated/conventional orchard management systems. The results revealed that stable isotope parameters in sugar, pulp and water were the most significant variables for differentiating between the regions. Good separation was achieved between the geographical regions in Slovenia based on the δ18O and δ2H values in water and Rb and S levels in the apple fruit juice. The most significant variables that distinguished between organically and integrated/conventionally cultivated apples were the 15N/14N ratio and antioxidant activity of the apple juice. Significant differences were also observed in the ascorbic acid content of the juice. Based on these results the number and types of apples and the minimum number of samples needed from the same region for determining geographical origin were determined. The second study was called “Organic ~ Conventional Apple Cultivation” (OCAC) and was performed in 2010 and 2011 in a Gala apple orchard. The aim was to determine the effect of different fertilizers allowed either in organic or conventional/integrated agricultural regimes on different parameters. Quality parameters, isotopic composition of C in sugars and in pulp together with N and elemental analysis were investigated. The following five fertilizers were applied: Biosol and Plantella organic (organic) and Ca cyanamide, KAN and UREA (mineral) at a rate of 60 and 120 kg of nitrogen per hectare. From the obtained data it was possible to differentiate between organic and integrated/conventional apple production when taking into account the following parameters: mass, skin and flesh firmness (SFF), total soluble solids (TSS), and the content of Cl as well as δ15N and δ13C in the pulp. The “Organic Cultivation ~ Geographical Origin” (OCGO) study, which took place during the 2011 and 2012 growing seasons included a greater number of samples and samples from five different geographical regions: Alpine, Dinaric,
