  2. 6. Muscle Thixotropy : Implications for Human Motor Control

    Author : Hans Axelson; Karl-Erik Hagbarth; Mikael Elam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Motor control; Skeletal muscle; Thixotropy; History-dependent; EMG; Voluntary contractions; Neurovetenskap; Neurology; Neurologi;

    Abstract : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. READ MORE

    Abstract : This thesis presents studies of molecular motors in interaction with nm-scale structures, as well as the development of a set of tools that can be used for the construction of custom-designed nano-transportation systems. In our studies, we have used the latest nanoscale technology and combined this with advanced results from chemistry and biomedical sciences. READ MORE

  5. 8. Infants in Control : Prospective Motor Control and Executive Functions in Action Development

    Author : Janna Gottwald; Gustaf Gredebäck; Claes von Hofsten; Daniela Corbetta; Uppsala universitet; []
    Keywords : infant development; action development; prospective motor control; executive functions; action planning; motor development; motion tracking; embodied cognition; developmental psychology; Psychology; Psykologi;

    Abstract : This thesis assesses the link between action and cognition early in development. Thus the notion of an embodied cognition is investigated by tying together two levels of action control in the context of reaching in infancy: prospective motor control and executive functions.

  6. 9. Tribology of hydraulic motor

    Author : Daniel Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : A radial piston hydraulic motor has several components involving sliding or rolling interfaces which may encounter tribological problems. Seizure is one of them and it results in complete stoppage of motion between the relatively moving components and has serious consequences in terms of the operation of a hydraulic motor. READ MORE

  7. 10. Neural Control of Movement : Motor Neuron Subtypes, Proprioception and Recurrent Inhibition

    Author : Anders Enjin; Klas Kullander; Samuel L. Pfaff; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor neuron; proprioception; recurrent inhibition; molecular marker; Ia afferent; development; transgenic mice; Renshaw cell; Neurobiology; Neurobiologi; Neuroscience; Neurovetenskap;

    Abstract : Movement is central for life, and all animals depend on accurate regulation of movement for purposeful behavior. There is great diversity of movements, ranging between simple and vital breathing movements to minute and subtle movements of the face used to communicate emotions. READ MORE
