5311. Odložilni veto Državnega sveta na Zakon o varstvu okolja : 32. nujna seja Odbora za infrastrukturo Državnega zbora, Ljubljana, 16. 3. 2016Božič Zoran, other performed works Abstract: Državni svet ugotavlja, da so spremembe in dopolnitve Zakona o varstvu okolja škodljive, saj dajejo večje možnosti interesom kapitala in ne omogočajo varovanja zdravega okolja. Državni svet je soglasno podprl zahtevo za odložilni veto.

5315. Učinki prožnih metod in pristopov v interdisciplinarnih delavnicah mednarodnega študijskega programa Medijske umetnosti in praksePeter Purg, 2016, published scientific conference contribution abstract Abstract: Četudi sistem zagotavljanja kakovosti glede na trenutno veljavna merila in standarde še dopušča rigidnejše oziroma (vase) zaprte izobraževalne koncepte, nas bo v prispevku posebej zanimalo, kako se kakovostno pedagoško delo lahko razvija v okviru (in paradoksu) mednarodne mobilnosti ter projektno-razvojne naravnanosti študijskega programa, oziroma šole. Osredotočili se bomo na konkretno empirijo in izsledke, ki izhajajo iz raziskav in razvoja naprednih izobraževalnih pristopov v dveh evropskih projektih, IDEATE.me in ADRIART.net. Oba sta v študijskem programu Medijske umetnosti in prakse (MAP) vzpostavila neko specifično kakovost, ki pa nima (in ne more imeti) zgolj pozitivnih učinkov na vse deležnike. Primerjalna diskusija izbranih mešanih izvedb interdisciplinarnih delavnic v mednarodnem podiplomskem programu MAP, navezanim na različne razvojne projekte in mobilnostne mehanizme, pokaže pet ključnih pozitivnih dejavnikov: odprtost za skupinsko delo in sodelovalnost; interdisciplinarna komunikacija in moderiranje; večkulturna komunikacija in moderiranje; celovit in odprt učni načrt ter prožna izvedba predmeta; ustrezna povratna informacija (ocena) vsem deležnikom.

5316. Under All the Hats of Quality : Balancing roles and responsibilities in academic quality assurance - as (high) quality teacher, scientist/artist, institutional coordinator, curriculum creator, peer evaluator ...Peter Purg, 2016, published scientific conference contribution abstract Abstract: The round table highlighted specific individual views on current trends and standards of academic quality in terms of (at least) three key roles in the study process: the coordinator, author / performer, peer evaluator... Participants confronted (often incompatible) views on these roles in terms of the quality of everyday academic practice, which on the one hand, introduces increasingly stringent and detailed standards and criteria - yet on the other rarely motivates academic staff to (consciously) achievement or development them! The round table attempted to find and compare the best practices of the criteria of transferring quality criteria into everyday practice of teaching, research and development -- thereby to identify the key points in common best practices for strategic planning of the quality system design at the level of school, programme, course, and last but not least the individual academic career.

5319. Removal of manganese in batch and fluidized bed systems using beads of zeolite a as adsorbentMina Jovanovic, Iztok Arčon, Janez Kovač, Nataša Novak Tušar, Bojana Obradovic, Nevenka Rajić, 2016, original scientific article Abstract: In this study the uptake capacity of Mn(II) ions by zeolite A beads was investigated for different initial Mn concentration (100e400 mg Mn dm^-3) in batch mode at 25e55 C. The obtained adsorption capacity varying from 30 to 50 mg Mn g^-1 demonstrated a high affinity of zeolite A towards Mn(II) present in solutions. Kinetic studies indicated the intra-particle diffusion as the rate limiting step up to 45 C with apparent diffusivities in the range (1.2e2.0) x 10^-13 m2 s^-1 and the activation energy of 21.9 kJ mol^-1, which implies strong interactions between the zeolite A and Mn ions. At 55 C ion-exchange became the rate limiting step. The adsorption isotherms were studied at 25 C showing that the Mn adsorption is the best described by the Langmuir model suggesting a homogenous zeolite surface. XPS analysis of the Mnloaded beads showed that there is no surface accumulation of Mn but an almost uniform Mn distribution inside zeolite A, whereas XANES and EXAFS suggested that the adsorption of Mn(II) was followed by the Mn(II) oxidation and oxide formation. Regeneration of the spent zeolite was examined in 8 adsorption/desorption cycles by a chelating Na2EDTA in a fluidized column. It has been found that zeolite A beads could be reused for at least 4 cycles with satisfactory Mn(II) adsorption efficiencies of about 70%.
