Fragmentation of molecular cations formed by electron-impact ionization is governed primarily by the redistribution of internal energy deposited during the collision event. A detailed understanding of how this energy drives the transition from bound vibrational motion to irreversible bond cleavage is essential for interpreting energy-resolved fragm...

Artificial intelligence (AI), especially generative artificial intelligence (GAI), is quickly changing education, work, and everyday life. Slovenia is an interesting example for studying these changes because it has adopted GAI very rapidly and there is already a growing number of empirical studies on its social and organisational impacts. This pa...

Delivering lectures in large student groups at higher education institutions, particularly at technical faculties, presents considerable pedagogical and organizational challenges. Individualized attention is significantly limited, making it difficult for instructors to adequately address the diverse learning needs of all students. Progressing too q...

Surface finishing of dental materials significantly influence their functional properties, biological compatibility, and long-term clinical performance. Given the diversity of materials used—including ceramics, metals, polymers, and bioactive composites—each material type necessitates a tailored approach to surface layer modification. T...

Waste management is becoming an increasingly important factor in the context of climate change, particularly due to methane emissions from landfills, which have a significantly stronger warming effect than carbon dioxide. The City of Prnjavor, facing challenges related to the growth of municipal waste and limited infrastructure, represents a repres...

Rigidity is one of the oldest psychological constructs to which, today, in the literature, traits such as egocentrism, authoritarianism, obsessiveness, inflexibility, and similar are associated. From the psychiatry's point of view, a rigid person is not a sick person, but a normal, healthy person with a special personality trait. The aim of this st...
