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...

This study examined the effects of Pb and Cd on seed germination and root growth of red clover (Trifolium pratense L.) under treatments with varying metal concentrations and equimolar amounts of β-diketonate, using an adapted bioassay method. The results showed that Pb and Cd reduced seed germination and root length in T. pratense. Root growth...

Sweet cherry pits, a significant fraction of agro-industrial bio-waste, are often underutilized despite their richness in bioactive compounds. In line with sustainable resource management and circular economy principles, their valorization using green extraction techniques has gained attention. Microwave-assisted extraction (MAE) and ultrasound-ass...

Nicotine is a naturally occurring bicyclic alkaloid, composed of a pyridine ring connected to a pyrrolidine ring. Possessing two heterocyclic nitrogen atoms, it behaves like a dibasic compound in water. The pyrrolidine nitrogen has a pKa of approximately 8.0 while the pyridine nitrogen has a pKa of 3.12-3.41. Therefore, at physiological pH of 7.4 a...

Arbutus unedo L. is a Mediterranean species rich in bioactive polyphenols, including gallic acid, catechin, quercetin, and arbutin, which exhibit pronounced inhibitory activity toward α-glucosidase and α-amylase, often exceeding that of the standard antidiabetic drug Acarbose. However, the practical valorization of phytotherapeutic form...

ABSTRACT This study investigates the influence of gamma irradiation on the thermal properties of polyolefins and polymer blends, aimed at improving polyolefin waste recycling. In addition to binary blends of isotactic polypropylene (iPP) and low-density polyethylene (LDPE), several commercial polymer samples were analyzed, including neat LDPE, nea...

This paper examines the relationship between different forms of work motivation of healthcare workers, whereby the motivation is conceptualised as a multidimensional construct shaped by the interaction of individual needs, organisational characteristics and the broader social context. The theoretical framework of the research is based on contempora...
