A new procedure is proposed to perform push-out tests in SiC/SiC composites. To avoid the interphase damage resulting from mechanical polishing, the sample is prepared with the help of a ion slicing process. Initiation of debonding is detected on the mechanical response. A finite fracture mechanics approach allows to use the force at debonding onset to estimate the interfacial fracture energy.

Actin polymerization has been shown to be sufficient to propel curved objects, for example beads and vesicles coated with the Listeria monocytogenes protein ActA. Recent studies suggest that actin polymerization on flat surfaces can also provide the propulsive force to push them forward.

During push switch operation, tactile feedback is crucial in determining whether the operation will be successful. However, to enhance and ensure usability, actuation force should not increase. Herein, a method improve during by designing operating sound proposed. In first experiment, investigate acoustic characteristics of high sound, participants evaluated recorded commercial sounds through h...

OBJECTIVE To evaluate the push-out bond strength of Biodentine (BD) in comparison with two available calcium silicate based materials, bioaggregate (BA) and ProRoot MTA (WMTA). MATERIALS AND METHODS One hundred and twenty-three Root dentin slices of freshly extracted single Rooted human teeth were randomly divided into three groups (n = 41) according to the used test material: WMTA, BA, BD. A...

OBJECTIVE The aim of this study was to determine bonding properties of two types of fibre-reinforced composite (FRC) posts cemented into root canals of molars. Serrated titanium posts served as reference. METHODS Prefabricated carbon/graphite FRC posts with cross-linked polymer matrix and individually formed glass FRC posts with interpenetrating polymer network (IPN) polymer matrix were compa...

Real-time force and visual information during MWCNT manipulation is required for online controlling MWCNT assembly based on atomic force microscope (AFM). Here realtime three-dimensional (3D) interactive forces between probe and sample are obtained according to PSD signals based on the proposed force model, and MWCNT manipulation process can be online displayed on the visual interface according...

This study attempted to clarify the factors responsible for change in hand propulsive force when stroke frequency was changed crawl. Eight male swimmers performed five 20-m front crawls. The first trial involved maximal effort, and then controlled during next 4 trials. instructed frequencies were 70%, 80%, 90%, 100% of effort trial. To calculate resultant force, pressure acting on palm dorsum m...

OBJECTIVE To investigate the influence of workload setting (speed at constant power, method to impose power) on the propulsion technique (i.e. force and timing characteristics) in handrim wheelchair propulsion. METHOD Twelve able-bodied men participated in this study. External forces were measured during handrim wheelchair propulsion on a motor driven treadmill at different velocities and con...
