Advances in formal Slavic linguistics 2017
2020, proceedings of peer-reviewed scientific conference contributions (international and foreign conferences)
Abstract: Advances in Formal Slavic Linguistics 2017 is a collection of fifteen articles that were prepared on the basis of talks given at the conference Formal Description of Slavic Languages 12.5, which was held on December 7-9, 2017, at the University of Nova Gorica. The volume covers a wide array of topics, such as control verbs, instrumental arguments, and perduratives in Russian, comparatives, negation, n-words, negative polarity items, and complementizer ellipsis in Czech, impersonal se-constructions and complementizer doubling in Slovenian, prosody and the morphology of multi-purpose suffixes in Serbo-Croatian, and indefinite numerals and the binding properties of dative arguments in Polish. Importantly, by exploring these phenomena in individual Slavic languages, the collection of articles in this volume makes a significant contribution to both Slavic linguistics and to linguistics in general.

PHOTOLYSIS AND ECOTOXICITY OF THE ANTIBIOTIC CIPROFLOXACINKetevan Neparidze
, 2017, undergraduate thesis
Abstract: Over the last few decades, numerous pharmaceuticals coming from domestic sewage, livestock, hospitals and industries have been determined in ground, surface and drinking waters. A common example of these pollutants are fluoroquinolones, which are powerful antibiotics used in human and veterinary medicine. The presence of fluoroquinolones in the environment even at low concentration constitutes a threat to ecosystems and human health because they can lead to bacterial resistance issues. Up to now the environmental impacts of fluoroquinolones and their degradation products are not fully understood but it is known that they can negatively affect plants and aquatic organisms. In this study the degradation of ciprofloxacin (CIP) present in synthetic freshwater was investigated under simulated sunlight. Concentrations before and after degradation were determined using HPLC-DAD. The mineralisation rate of the treated solution was monitored on a total organic carbon analyser. The ecotoxicity of the initial samples and the degradation mixtures was assessed on organisms belonging to different trophic levels: a marine bacterium (Vibrio fischeri), a freshwater invertebrate (Daphnia magna) and seed clover (Trifolium repens). In parallel, the EC50 of CIP was determined for all organisms. The Vibrio fischeri and Trifolium repens tests showed that EC50 value was more than 250 mg/L and for Daphnia magna was 190 mg/L. Photolysis of CIP showed that after 90 min of irradiation, CIP was almost totally degraded (99%). Photolysis process of CIP led to the formation of toxic by-products towards Vibrio fischeri. The toxicity test results on Trifolium repens did not show significant difference between the control and the treated plants. Thus, CIP and its degradation products have no effect on the germination or root length of Trifolium repens. Tests on Daphnia magna after 240 min irradiation showed a 94% reduction of the toxic effect. Non-purgeable organic carbon (NPOC) analysis showed that there is no significant mineralisation of the sample even after 240 min of irradiation.

, 2015, published scientific conference contribution abstract
Abstract: Although both syntax and number words can indicate quantity, only numbers can specify large exact quantities. Do children use
syntax to bootstrap preliminary meanings of number words before mastering precise meanings? We compared errors across
languages on a Give-a-Number task in non-knowers (who have adult meanings for no number words) and subset knowers (who
have adult meanings for fewer than five number words). Participants included learners of English, Spanish, French, and two
dialects of Slovenian. One dialect, Central Slovenian, has rich number morphology including singular, dual, small plural, and large
plural (for 5+). In all languages, subset knowers and some non-knowers demonstrated better than random responding for at least 2
number words beyond the largest number word they comprehended precisely. Additionally, Central Slovenian-learning non- and 1-
knowers responded more accurately to requests for higher numbers than their counterparts in other languages, suggesting that rich
plural marking may bootstrap number word meanings.
Keywords: knower level, grammatical number, acquisition of number words, bootstrapping
