1. Pathways to Alternative Transport Mode Choices among University Students and Staff—Commuting to the University of Maribor since 2010Branka Trček, Beno Mesarec, 2022, izvirni znanstveni članek Opis: The study of commuting behavior at the University of Maribor (UM) was the subject of our
research, which focused on the building complex of the four technical faculties (BCTF) and was based
on the analysis of two questionnaire surveys (with 1057 and 462 respondents, respectively) and the
transport policies implemented at the study site from 2010 to 2020. The research aimed to identify the
factors influencing student and staff mode choice/shift over a decade period and to understand the
weaknesses, strengths, and opportunities for improving sustainable mobility at the university. Since
2010, active commuting has predominated among students, while car use has decreased by 22%.
Female students were 16% more likely to walk than their peers, while male students were 5% and
12% more likely to use bicycles and cars, respectively. Active commuting and car use by staff have
not changed since 2010, and there was an insignificant difference between genders, 63% of whom
used cars. Mode shifts were primarily related to trip origins, subsidization of bus use, availability or
unavailability of free parking, and parking fees. Questionnaire responses were a powerful tool for
finding the most effective interventions to manage transport at universities. The results also suggest
that transport policies can be more effective if they are planned in coordination with housing policies.

2. How the volume of traffic affected air quality during the extreme event of COVID-19 lockdown in a small cityBranka Trček, Rok Kamnik, 2022, izvirni znanstveni članek Opis: The extreme traffic measures during the COVID-19 lockdown provided a unique opportunity to gain better insight into the relationship between traffic characteris-tics and NO2 concentrations in Maribor, a small Slove-nian city. NO2, traffic and meteorological data were sta-tistically processed in detail for March and April 2018, 2019 and 2020 to get a historical insight and to exclude the specifics of the lockdown period. The extreme event resulted in an average reduction of road traffic of 42%. The decrease in the number of passenger cars ranged from 33.9 to 60.3% per day with the largest decrease on the motorway. Daily averages of heavy goods traffic de-clined on the motorway and the expressway by 24.6% and 7%, respectively. Traffic characteristics were reflect-ed in a 24–27% decrease in NO2 concentrations at the urban station. The change is smaller than the change in traffic volume, which could be explained by the change in the composition of the vehicle fleet due to the increase in NO2-dominant traffic sources, e.g. diesel heavy goods vehicles. The presented results are relevant for improv-ing air quality and sustainable mobility management in small cities. They highlight the important role of reor-ganisation of heavy goods traffic in urban logistics.

3. Impact of the Hydroelectric Dam on Aquifer Recharge Processes in the Krško Field and the Vrbina Area : Evidence from Hydrogen and Oxygen IsotopesBranka Trček, Beno Mesarec, 2023, izvirni znanstveni članek Opis: The impact of the damming of the Sava river for the Brežice hydroelectric power plant on the rise of the groundwater level was studied in the intergranular aquifer of the Krško field and the Vrbina area, Slovenia. The study is based on the application of hydrogen and oxygen isotopes (18O, 2H and 3H). Parameters were determined for precipitation, surface water, and groundwater for periods before and after the filling of the accumulation basin, with the aim of evaluating the groundwater–surface water interaction and to elucidate the impact of the hydroelectric dam on aquifer recharge processes. The results show the proportions of the surface water component in groundwater sampled from four wells at high and low water conditions, separately for the period before and after the filling the accumulation basin. After filling the accumulation basin, the proportion of the Sava river component at high water conditions increased from 60% to 80% in the Brege and Drnovo wells (drinking water resources), from 50% to 80% in the Cerklje well and to almost 100% in the near-river NEK well. Combined with previous studies, the results provide important information about the direction of groundwater flow in the aquifer and improve the conceptual model of the study site.

4. Suggestions and solutions for enhancing active commuting to the University of Maribor and advancing ▫$CO_2$▫ emission reductionBeno Mesarec, Branka Trček, 2024, izvirni znanstveni članek Opis: This study investigated commuting behavior at four technical faculties (BCTF) in Maribor. The main aim was to provide suggestions and solutions for challenges related to active commuting to the BCTF, while promoting advancements in CO2 emission reduction. The research methodology was based on analyses of a questionnaire survey and calculations of CO2 emissions. The results indicate that implementing measures to promote walking, bicycling and the use of city and regional public transport, in conjunction with supportive housing and parking policies, has the potential to eliminate car trips within 0–1 km of the BCTF and reduce car trips from other zones in favor of active commuting by 30% to 50%. These proposed transport scenarios could lead to an annual reduction in CO2 emissions ranging from 17% to 29%. The greatest potential for CO2 savings is observed within 0–5 km of the BCTF, where a shift to walking and bicycling could reduce emissions by up to 44%. The results also highlighted a notable disparity, indicating that students with term-time accommodations emitted 3.5 times and 4.1 times less annual CO2 within 0–5 km of the BCTF compared to students and staff commuting daily from their permanent residences in the city.

6. Primerjava metod za izračun hrupa NMPB 1996 in CNOSSOS ob uporabi realnih in modelskih vhodnih podatkovTamara Bračko, 2019, magistrsko delo Opis: V magistrskem delu smo proučevali obremenjenost okolice Ceste proletarskih brigad v Mariboru s hrupom cestnega prometa. Izračune hrupa smo opravili po metodah NMPB 1996 in CNOSSOS ob uporabi realnih in modelskih vhodnih podatkov. Pozornost smo namenili postopku pridobivanja vhodnih podatkov, njihovi kakovosti in analizi rezultatov različnih metod. Za različne scenarije smo izračunali zvočno moč cestnega prometa in izdelali karte hrupa. Pridobljeni podatki o površinah raziskovalnega območja, na katerih so kazalci hrupa prekoračeni, so bili osnova za izračun števila stavb in prebivalcev, ki so obremenjenih s hrupom cestnega prometa, in predloge omilitvenih ukrepov. Rezultati so pokazali, da je metoda NMPB 1996 primernejša za uporabo, saj ima metoda CNOSSOS pomanjkljivosti v zvezi s širjenjem hrupa. Z realnimi vhodnimi podatki se bolje opiše stanje okolja kot z modelskimi, vendar je njihovo pridobivanje kompleksnejše, dolgotrajnejše in dražje, zato se njihova raba priporoča v primeru študij na manjših in gosto poseljenih območij z močno obremenjenimi cestami.

7. Obremenjenost okolja s hrupom na avtocestnem odseku Cogetinci - Vučja vasPetra Filipič, 2018, diplomsko delo Opis: Diplomsko delo obravnava temo obremenjenosti okolja s hrupom na izbranem odseku avtoceste Cogetinci−Vučja vas. Da bi kvalitetno zaščitili okolje pred onesnaževanjem, se največkrat izvedejo protihrupni ukrepi, ki se razlikujejo glede na posamezen teren. S pomočjo zbranih podatkov prometnih obremenitev je prikazana rast oz. padec vozil po posameznih kategorijah in letih. Kljub različnim rezultatom je mogoče razbrati enakomerno rast prometa vseh vozil. Po anketi, ki se je izvedla spletno in osebno pri posameznikih, smo ugotovili, da v letih od odprtja avtoceste do danes hrup prebivalcev po večini ne obremenjuje, kakovost življenja pa se zaradi novogradnje ni spremenila ali poslabšala. Dodatni zaščitni ukrepi niso potrebni. Prikazani so tudi podatki o povoženju živali na obravnavanem odseku v preteklih letih. Zabeleženi podatki kažejo, da se je največ povoženj zgodilo na začetku odprtja, kasneje se je številka občutno zmanjšala. Za zmanjšanje števila takšnih vrst nesreč se predlaga gradnja podhodov in uvedba zvočnih in svetlobnih naprav, ki živali odvračajo od prečkanja ceste.

8. Analiza vpliva življenjskega cikla proizvodnje aluminijevih drogov na okoljeAnja Selinšek, 2018, magistrsko delo Opis: V magistrskem delu smo s pomočjo delovnega okolja družbe Talum iz Kidričevega na konkretnem primeru proizvodnje aluminijevih drogov prikazali uporabo metode analize življenjskega cikla. V teoretičnem delu magistrskega dela je predstavljen razvoj metode in njen podrobnejši opis s pomočjo standardne osnove. Skozi razčlenjen proizvodni proces smo opisali vsak korak proizvodnje posebej ter hkrati razložili njegove bistvene značilnosti. V raziskovalnem delu magistrskega dela smo na podlagi veljavnih standardov zbrali in analizirali informacije o vhodnih in izhodnih tokovih posamezne procesne enote. Dobljene informacije smo zajeli v programu GaBi Education ter tako številčno ovrednotili izbrane kazalnike obremenjevanja okolja. V sklepnem delu magistrskega dela je sledil še poskus okoljskega optimiziranja z modeliranjem različnih scenarijev transportnih poti uvoza osnovne surovine – glinice.

10. Ravnanje z odsluženim fotonapetostnim sistemomMartin Špes, 2017, magistrsko delo Opis: Fotonapetostni sistemi s pomočjo svojih komponent pretvarjajo svetlobno energijo v električno. Njihovo število se iz leta v leto povečuje, posledično tudi zaradi tega, ker koristijo energijo iz obnovljivih virov. Zaradi specifike fotonapetostnega modula nastopijo težave, ko ta konča kot odpadek, saj so njegovi postopki recikliranja precej dragi in zahtevni.
V magistrskem delu je predstavljen celoten fotonapetostni sistem, njegove komponente in njegove možnosti recikliranja. Analizirano je stanje slovenskega fotonapetostnega trga in stanje na področju slovenske zakonodaje, ki zajema odpadne fotonapetostne module. Na podlagi analize o stanju slovenskega fotonapetostnega trga je podana ocena o količinah odpadnih fotonapetostnih modulov, ki jih lahko pričakujemo v naslednjih letih. Da bi odsluženim fotonapetostnim modulom povečali dodano vrednost, smo predstavili idejo, da fotonapetostne module povežemo s krožnim gospodarstvom.
