  - Polish Maritime Research - Year 2021

  The article presents the possibility to control the real operation process of an arbitrary device installed in the marine power plant based on the four-state semi-Markov process, being the model of the process, which describes the transition process of operational states of the device and the transition process of its technical states. All these states are precisely defined for the ship main engine (SG). A hypothesis is proposed...

  Publication

  • W. Litwin
  • C. Dymarski

  - TRIBOLOGY INTERNATIONAL - Year 2016

  Water lubricated bearings are popular in sliding bearings of marine propeller shafts, turbines and pump shafts. Such popularity is partly due to their simple construction which also means a relatively affordable price. In practical experience one may also observe cases of rapid wear or even malfunctions of this bearings, some of which may be caused by insufficient flow of lubricant leading to overheating. The conducted...

  Enterococci, ubiquitous colonizers of humans and other animals, play an increasingly important role in health-care associated infections (HAIs). Acquisition of resistance determinants not only seriously limits available therapeutic options but also increases available gene pool for other species. It is believed that the recent evolution of two clinically relevant species, Enterococcus faecalis and Enterococcus faecium occurred...

• Concrete-filled FRP tubular members in marine and bridge structures

  Publication

  • M. Abramski

  - Year 2020

  Concrete core of the concrete-filled tubes (CFTs) with circular cross-section is in the case of an axial compression subjected to a spatial state of compressive stresses. This state leads to enhancement in the concrete strength. The enhancement is utilized in Eurocode 4 design procedures for CFSTs (i.e. CFTs with tube made of steel). The structural design of CFFTs (i.e. CFTs with tube made of Fibre Reinforced Polymer - FRP) is...

  Procedury analityczne oznaczania zwiazków cynoorganicznych w osadach morskich skladają się z wilu operacji i czynnosci (pobieranie próbek, wstępne przygotowanie, transport, oznaczenia końcowe). Zazwyczaj procedury te charakteryzują się dużą praco- i czasochłonnością. W pracy omówiono podstawowe źródła błędów zwiazane z w/wym etapami postepowania analitycznego oraz przedstawiono sposoby im zapobiegania.
