Towards an analysis framework for operational risk coupling mode: A case from MASS navigating in restricted waters
PublicationMaritime Autonomous Surface Ships (MASSs) constitute highly interconnected and tightly coupled multistate systems. Incorporating the coupling effects of both interactions and dependencies is centrally important to ensure navigation safety of MASSs. This paper proposes a framework for examining the coupling effects in the operational modes (OM) of MASSs. Failure Modes (FMs) of MASSs related to interactions with the environment and...

The common effect of hydrophobic and electrophilic types of hydration dependent on protonation in the sec-butyloamine/HCl/H2O system studied by FTIR spectroscopy
PublicationZbadano hydratację sec-butyloaminy w zależności od pH roztworów wodnych przy pomocy spektoskopii FTIR, z zastosowaniem techniki rozcieńczenia izotopowego HDO w H2O. Dane widmowe poddano analizie przy pomocy ilościowej metody widm różnicowych. Stwierdzono, iż wiązania wodorowe cząsteczek wody tworzących klatratopodobną otoczkę hydratacyjną wokół aminy ulegają wzmocnieniu na skutek oddziaływania z grupą elektrofilową aminy.

The comparison of antioxidant properties and nutrigenomic redox-related activities of vitamin C, C-vitamers, and other common ascorbic acid derivatives
PublicationThe term ‘vitamin C’ describes a group of compounds with antiscorbutic activity of L-ascorbic acid (AA). Despite AA’s omnipresence in plant-derived foods, its derivatives have also been successfully implemented in the food industry as antioxidants, including the D-isomers, which lack vitamin C activity. This study aimed to determine the relationship between redox-related activities for five derivatives of AA using electrochemical,...
