In this study a method has been demonstrated by which
the departure from nucleate boiling ratio (DNBR) can be
readily determined for nuclear transients through application
of the COBRA-IIIC/MIT computer code. For input,
boundary conditions were specified relating the time-dependent
variations of core inlet coolant temperature,
system pressure, core heat...
Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
Achlys triphylla, a member of a medicinally active family
