Rate of torque development scaled to maximum torque available is velocity dependent.

The influence of angular velocity on rate of torque development (RTD) is unknown, despite the inverse, curvilinear torque-velocity relationship for angle- and velocity-specific maximum available torque (T) being well-established. This study investigated the relationship between angular velocity and RTD scaled to T. In 17 participants, tetanic contractions (100-Hz) of the knee extensors were evoked as the knee was passively extended at different iso-velocities between 0° s and 200° s.

Cellulose nanofibers from recycled and virgin wood pulp: A comparative study of fiber development.

The global abundance of recycled pulp has introduced opportunities for cellulose nanofiber (CNF) production at lower energy due to the partially fibrillated nature of recycled pulp. This study investigated the potential of recycled pulp as a feedstock for CNF production, comparing recycled bleached de-inked pulp (DIP) predominantly from eucalyptus fibers with virgin bleached eucalyptus kraft (BEK) pulp. The specific energy consumption for CNF production with 10,000 PFI refiner revolutions and 1 homogenization pass was 7 % lower with recycled pulp.
