Analytical solutions for oil spreading on the sea are deduced when the pollutant source fluctuates with time for a simple rectangular geometry. Both asymmetrical and symmetrical solutions in the direction perpendicular to the uniform tidal stream are derived. The asymmetrical solution, though ad hoc

A variety of concentrations of the IMPase inhibitor L690,330 were added to sea urchin embryos. Immediate arrest of development was obtained for concentrations from 7.5 mm on. Concentrations lower than 3.5 mm permitted gastrulation but inhibited skeletogenesis and disturbed elongation along the anima
We have reinvestigated the existence of cyclical fluctuations of protein synthesis and have examined the effects of reducing it in early embryos of the purple sea urchin, Strongylocentrotus purpuratus. The results show that protein synthesis increases linearly during the first 45-60 minutes after fe
