This thesis examines the transient and steady-state temperature performance
of a rotary regenerative heat exchanger. In contrast to previous
studies on this problem, fluid flow in the circumferential direction was
considered. Appropriate modeling was included to measure the effect of
carry-over on the differential equations describing mass and energy
conservation....
The mycosporins, formerly called P310's are secondary metabolites
of fungi closely associated with fungal reproductive processes that
require light. The structurally related iminomycosporins are found in
marine plants and animals and may also have functions related to
light. In this study, approaches toward the asymmetric synthesis of
the mycosporins are...
