The concentrations of elements/metals, nicotine, flavor chemicals and acids were compared in the e-liquids of unused and used first-generation electronic cigarettes (ECs) that were stored for 5-10 years. Metal analysis was performed using inductively coupled plasma optical emission spectroscopy; nicotine and flavor chemical analyses were performed ...
V magistrski nalogi smo zajeli in prikazali zunanje parametre kakovosti in senzorične lastnosti 49 starih sort jablane, obenem pa tudi notranje parametre kakovosti, ki skupaj z zunanjim izgledom igrajo pomembno vlogo pri odločanju potrošnika. Vsebnosti posameznih sladkorjev ter organskih kislin smo analizirali s pomočjo tekočinske kromatografije vi...

In present work, the inhibition performance of the Portulaca Grandiflora Leaf Extract (PGL), as environmental-friendly corrosion inhibitor, for low-carbon steel in 0.5 M hydrochloric acid solution at variable inhibitor concentrations and temperatures is evaluated by mass loss technique. The dependent variable was corrosion rate, while the independe...
Chitosan acquires bacteriostatic properties via protonation of its amino groups. However, much of the literature assumes that chitosan itself inhibits the growth of bacteria. This article presents a comparative study of chitosan nonwovens modified with various acids, including acetic, propionic, butyric, and valeric organic acids, as well as hydroc...
Thinning and pruning are expensive cultural practices in peach cultivation, but essential to obtain adequate production. This study evaluated the effects of combining two pruning (four and six scaffold branches) and three thinning (low, medium, and high crop load) levels on yield and fruit quality of four different flat peach cultivars, trained as ...
The permeation of amino acids and di-peptides with different hydrophobicities across the oil phase in W/O/W double emulsions was investigated at different concentrations, considering the pH of the aqueous phase. Moreover, the particle size, yield of entrapped water and release kinetics of the double emulsions was evaluated as a function of time. Re...

Abstract—The electrochemical properties of protective epoxy polymer coatings with different designs are studied with electrochemical impedance spectroscopy upon exposure in water and aqueous solutions of sulfuric acid. It is found that both the active resistance of the epoxy coating Rct and resistance of the transition layer Rdl decrease upon long-...
This review highlights the importance of odd and branched chain fatty acids (OBCFAs) and dietary factors that may affect the content of milk OBCFAs in dairy cows. Historically, OBCFAs in cow milk had little significance due to their low concentrations compared to other milk fatty acids (FAs). The primary source of OBCFAs is ruminal bacteria. In gen...
Delo opisuje, kaj so biološki pufri, kakšne lastnosti imajo, njihovo kemijsko sestavo, kako jih lahko pridobimo ter za katere pogoje so najprimernejši. Opisano je tudi, kako pufri in pH vplivajo na lastnosti proteinov ter kako vplivajo na rastlinske in živalske sisteme. Proteini se spreminjajo ali celo denaturirajo pri različnih pH / da bi jih ohra...
Plant-derived conjugated linolenic acids (CLnA) have been widely studied for their preventive and therapeutic properties against diverse diseases such as cancer. In particular, punicic acid (PunA), a conjugated linolenic acid isomer (C18:3 c9t11c13) present at up to 83% in pomegranate seed oil, has been shown to exert anti-cancer effects, although ...
