Sterke buikspieren spelen een cruciale rol bij rompstabilisatie en het verminderen van lumbale stress, wat essentieel is voor sportprestaties en blessurepreventie. Bovendien is gesuggereerd dat asymmetrie in spieromvang van de rectus abdominis blessurerisico kan vergroten. Het verminderen van deze asymmetrie …

BACKGROUND AND AIMS: We aimed to investigate the test-retest reliability and validity of ultrasound for two commonly used types of transducer, using different methods for the estimation of muscle size and echo intensity (EI). METHODS: Fourteen healthy adults were included in this study. Ultrasound images …

Processes have been developed to integrate CIGS solar foils directly in plastic or composite based products. Using injection moulding and vacuum forming it turned out that mechanical stress is applied to the solar foil upon cooling. Using intermediate stress relief layers such as polyolefin this could …

OBJECTIVE: To evaluate the influence of abutment geometry on papillary fill in the esthetic zone in a delayed crown protocol. MATERIALS AND METHODS: Twenty-six subjects received two non-adjacent endosseous implants in the esthetic zone. Functional temporary crowns were installed 17-19 weeks later, using …
