Collision simulation of river-sea ship is accomplished based on nonlinear finite element method. Firstly, we discuss the development of collision analysis methods including theoretical methods, empirical formula method, experimental techniques and numerical analysis methods, and introduce the Central Difference Method adopted in the collision simulation. Then, model of ship structure and rigid ...

Molecular mechanisms by which the Src homology 2 domain-containing inositol 5-phosphatase (SHIP) negatively regulates phagocytosis in macrophages are unclear. We addressed the issue using bone marrow–derived macrophages from Fc Ror SHIP-deficient mice. Phagocytic activities of macrophages from Fc RII(b) / and SHIP / mice were enhanced to a similar extent, relative to those from wild type. Howev...

Ship grounding is one of the primary maritime navigation casualties and a result of an error made by the navigating officer, of a technical failure on vital ship equipment or of force majeure. In order to decrease the risk of grounding in such cases, this paper explores the ship movement during navigation when an extraordinary event occurs, such as steering system failure that affects the vesse...
