5205. Multiple and Short Wh-Movement as Wh-Movement to the PeripheriesPetra Mišmaš, 2016, objavljeni povzetek znanstvenega prispevka na konferenci Opis: In the talk I use Slovenian to explore the parallel behaviour of questions with multiple whmovement and questions with short movement (i.e. wh-questions in which at least one wh-phrase moves to the clause initial position but one moves to a clause internal position, cf. Citko (2010)). Based on the similarities, I argue that in both cases wh-phrases undergo wh-movement to a ‘Periphery’ – short wh-movement to the Low Periphery in the sense of Belletti (2004), and multiple wh-movement to the Left Periphery in the sense of Rizzi (1997).

5207. Synthesis, Structure and Antimicrobial Property of Green Composites from Cellulose, Wool, Hair and Chicken FeatherChieu Tran, Franja Prosenc, Mladen Franko, Gerald Benzi, 2016, izvirni znanstveni članek Opis: Novel composites between cellulose (CEL) and keratin (KER) from three different sources (wool, hair and chicken feather) were successfully synthesized in a simple one-step
process in which butylmethylimidazolium chloride (BMIm+Cl-), an ionic liquid, was used as the sole solvent. The method is green and recyclable because [BMIm+Cl-] used was recovered for reuse. Spectroscopy (FTIR, XRD) and imaging (SEM) results confirm that CEL and KER remain chemically intact and homogeneously distributed in the composites. KER retains some of its secondary structure in the composites. Interestingly, the minor differences in the structure of
KER in wool, hair and feather produced pronounced differences in the conformation of their corresponding composites with wool has the highest α-helix content and feather has the lowest content. These results correlate well with mechanical and antimicrobial properties of the composites. Specifically, adding CEL into KER substantially improves mechanical strength of [CEL+KER] composites made from all three different sources, wool, hair and chicken feathers (i.e., [CEL+wool], [CEL+hair] and [CEL+feather]. Since mechanical strength is due to CEL, and CEL has only random structure, [CEL+feather] has, expectedly, the strongest mechanical property because feather has the lowest content of α-helix. Conversely, [CEL+wool] composite
has the weakest mechanical strength because wool has the highest α-helix content. All three composites exhibit antibacterial activity against methicillin resistant S. aureus (MRSA). The antibacterial property is due not to CEL but to the protein and strongly depends on the type of the
keratin, namely, the bactericidal effect is strongest for feather and weakest for wool. These results together with our previous finding that [CEL+KER] composites can control release of drug such as ciprofloxacin clearly indicate that these composites can potentially be used as wound dressing.

5208. Microfluidic flow injection thermal lens microscopy for high throughput and sensitive analysis of sub-μL samplesMingqiang Liu, Sara Malovrh, Mladen Franko, 2016, izvirni znanstveni članek Opis: An analytical method combining microfluidic flow injection analysis (μFIA) with thermal lens microscopy (TLM) was developed for high throughput and sensitive analysis of sub-μL samples. Performance of the μFIA-TLM was validated for detection of hexavalent chromium [Cr(VI)] in water samples. At different sample injection volumes, detection positions and flow rates, influences of the reaction time and the diffusion of Cr-diphenylcarbazone (DPCO) complexes on the μFIA-TLM signal were investigated. Photodegradation of the Cr-DPCO complex was clearly observed when the absorbed photons per Cr-DPCO is above 1600. After optimization of the TLM with respect to rapid flows (up to 10 cm/s), we achieved a limit of detection of 0.6 ng/mL for Cr(VI) in a 50-μm deep channel. Impacts of interfering ions [V(V), Mo(VI), Fe(III)] on the Cr(VI) determination were found to be small. Cr(VI) in real samples from a cement factory were determined and found in good agreement with results of spectrophotometry. This μFIA-TLM shows advantages over its conventional counterpart, such as eliminating additional sample conditioning, reducing over 100 times the sample consumption to sub-μL and over 10 times the time required for one sample injection to a few seconds (up to 20 samples/min). The optimized μFIA-TLM setup can be applied for fast and sensitive analysis of nonfluoresent sub-μL samples in rapidly flowing mediums.

5210. New Collaboration Forms in Site-specific Blended Courses Abroad: : Lessons Learned in the ADRIART.net Curriculum Development ProjectPeter Purg, Daniela Brasil, 2016, izvirni znanstveni članek Opis: A condensed programme of international courses with site-specific focus was developed as part of the collaborative art study programme Media Arts and Practices. Among higher-education partners from Italy, Austria, Croatia, and Slovenia the collaboration crossed the realms of new-media and contemporary art, film, animation, photography and scenography. Aiming at art pedagogy practitioners including art-school managers, who plan to develop or implement similar forms of intensive courses or programmes, the article discusses several key phenomena emerging among different stakeholders of the artistic or media-production education process. A plethora of research-and-development data, gathered along the three years of the collaborative study programme provision and intensive short-term course deployments, were condensed into lessons-learned that focus around the aspects of (blended) course design, interdisciplinary teaching and production methods, academic feedback and critique, as well as impact on local stakeholders. By shedding multi-layered light at site-specific art pedagogy along four short case-comparisons (from Graz, Komiža, Rijeka, and Venice), the article reflects an important trend in the arts—increasingly hybrid, multidisciplinary practices. It shows how social and (aesth)ethical change is well possible within a culturally reflected art pedagogy-cum-production setting that can materialize a collective and meaningful impact on a specific site, and its social tissue.
