Critical assessment of Eurocode approach to stability of metal cylindrical silos with corrugated walls and vertical stiffeners.
PublikacjaPrzedmiotem artykułu było krytyczne oszacowanie podejścia w Eurokodzie odnośnie stateczności metalowych cylindrycznych silosów z blachy falistej i słupów. Obliczenia 3D wykonane stosując MES. Symulowano blachę gładką ze słupami belkowymi o zastępczej sztywności. W obliczeniach uwzględniono falistość blachy. Pokazano, że wzory normowe znacznie odbiegają od wyników MES.

Buckling resistance of a metal column in a corrugated sheet silo - experiments and non-linear stability calculations
PublikacjaThe results of experimental and numerical tests of a single corrugated sheet silo column’s buckling resistance are presented in this study. The experiments were performed in a real silo with and without bulk solid (wheat). A very positive impact of the bulk solid on the column buckling resistance occurred. The experimental results were first compared to the buckling resistance calculated by Eurocode 3 formulae. The comparison revealed that...

Limiting distribution of the three-state semi-Markov model of technical state transitions of ship power plant machines and its applicability in operational decision-making.
PublikacjaThe article presents the three-state semi-Markov model of the process {W(t): t 0} of state transitions of a ship power plant machine, with the following interpretation of these states: s1 – state of full serviceability, s2 – state of partial serviceability, and s3 – state of unserviceability. These states are precisely defined for the ship main engine (ME). A hypothesis is proposed which explains the possibility of application...

Why do G-quadruplexes dimerize through the 5’-ends? Driving forces for G4 DNA dimerization examined in atomic detail
PublikacjaG-quadruplexes (G4) are secondary structures formed by guanine-rich nucleic acid sequences and shown to exist in living cells where they participate in regulation of gene expression and chromosome maintenance. G-quadruplexes with solvent-exposed guanine tetrads show the tendency to associate together through cofacial stacking, which may be important for packaging of G4-forming sequences and allows for the design of higher-order...
