The Hawaiian-Emperor seamount chain is the ‘‘type’’ example of an age-progressive, hot spotgenerated intraplate volcanic lineament. However, our current knowledge of the age distribution within this province is based largely on radiometric ages determined several decades ago. Improvements in instrumentation, sample preparation methods, and new material obtained by recent drilling...
Calf death at or shortly after calving results in
losses of over 3.5 million calves annually in the
United States. About 45% of these losses are
caused by dystocia (delayed and/or difficult
parturition). The two principal factors involved
in dystocia are size of calf and age of cow.

Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP)
and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were
quantitated in the central nervous system (CNS) of the insect Manduca
sexta by competitive protein binding techniques. The M. sexta CNS
was found to contain a strikingly high level of cGMP, about...
β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...
