  1. 1. Orofacial dysfunctions in children and adolescents with myotonic dystrophy type 1 - evaluation and intervention

    Författare :Lotta Sjögreen; Göteborgs universitet; []
    Nyckelord :myotonic dystrophy type 1; children; facial expression; dysarthria; dysphagia; drooling; lip force; lip mobility; 3D motion analysis; oral screen;

    Sammanfattning : Myotonic dystrophy type 1 (DM1) is a slowly progressive neuromuscular disease. The overall aim of this thesis was primarily to describe the characteristics, prevalence, and development of orofacial functions in a group of children and adolescents with DM1 and secondly to investigate the effect of lip strengthening exercises.

  5. 4. Grease lubrication in radial lip seals

    Författare :Pieter Baart; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Rolling element bearings contain seals to keep lubricant inside and contamination outside the bearing system. These bearings are more often lubricated with grease rather than oil. Much knowledge is available on oil lubricated seals but a good understanding of grease lubricated seals is lacking. LÄS MER

  7. 5. Tribological Aspects of Pneumatic Clutch Actuators

    Författare :Frida Riddar; Åsa Kassman Rudolphi; Roland Larsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; friction; PTFE transfer; anodised aluminium; NBR rubber lip seal; silicone grease; casting; extrusion; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : A clutch actuator is used in a vehicle to transmit movement and force from the clutch pedal to the release bearing of the clutch. A pneumatic clutch actuator consists of an anodised aluminium cylinder, inside of which a piston, with a rubber lip seal and a PTFE guiding ring, slides. The system is lubricated with silicone grease before assembly. LÄS MER
