3. 2. Roughest hour – approaches to ship hull fouling management

   Författare :Dinis Oliveira; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vessel performance; fouling control coatings; hull grooming; ship resistance; adhesion strength; in-water hull cleaning; biofouling; roughness; turbulent boundary layer;

   Sammanfattning : Submerged surfaces at sea are colonized by a high diversity of sessile (i.e. attached) life forms. As the merchant fleet capacity increases, responding to growth in demand for seaborne transport, so does the hull wetted surface area that is prone to colonization by these sessile organisms, i.

   Sammanfattning : The dissertation focuses on the Haredi (ultra-orthodox Jewish) journal The Jewish Observer, published since 1963 by Agudath Israel of America, suggesting that the publisher uses the journal as an instrument to help the readers to maintain a distinct Haredi identity in urban, non-Haredi environments and not only in their own, isolated milieu. The articles of the journal are understood as resources, aiming to help the readers to consider themselves to be members of an »imagined ghetto». LÄS MER

7. 5. Wear of piston rings in hydrostatic transmissions

   Författare :Ulf Skytte af Sätra; Sören Andersson; Kenneth Holmberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; piston ring; surface roughness; texture; coating; wear; hydraulic motor; Construction engineering; Konstruktionsteknik; Mechanical engineering; Maskinteknik;

   Sammanfattning : This study focuses on the wear of piston rings in a hydraulic radial piston motor. The piston ring has to satisfy increasing demands for reliability and longer service life. It has two contacting surfaces, the face and the flank, and operates under a boundary lubrication state. LÄS MER
