A cylindrical bushing subjected to a stationary cyclic load is analysed with emphasis on the amplitude and frequency dependent damping and modulus. The material parameters were determined from a dynamic shear test, in terms of a viscoelastic-elastoplastic model. Using an overlay of finite element meshes, the material model was implemented in a finite element model of the cylindrical bushing and su

Utifrån ett kulturanalytiskt perspektiv undersöker artikeln på vilket sätt ordet andetag används i språket och på vilka sätt det är kopplat till den kroppsliga upplevelsen av att andas. Metaforiskt används ordet andetag synonymt med liv i det svenska språket. Härigenom synliggör ordet de kulturella klassifikationer som finns mellan liv och död. Andetaget är också en del av en kroppslig situation d

Anaesthesia with closed anaesthetic systems demands knowledge of the physiology of the patients and of how the various anaesthetic gases behave in the organism as only the gases which the patients produces and absorbs are eliminated and replaced. The system is educational as it provides knowledge of the genuine absorption of oxygen and anaesthetic gases. The method is favourable to the environment
At present, when economy and environment receive high priority, the ideal anaesthesia system with inhalation anaesthetics is a closed circle system in which only the gases which the patient consumes or produces are replaced or eliminated. Low-flow (LF) anaesthesia in which the fresh gas flow which is employed in a closed system, provides a stable system compares with closed anaesthesia systems. Co
