Shifts in limiting nutrients in an estuary caused by mixing and biological activity
limiting nutrients mixing biological activity
2014/4/8
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a
nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...

Chromones pyrazoles glucopyranosyl bromide glucosylation
2010/10/15
A convenient route to synthesize some new medicinally important 7-hydroxy-3-pyrazolyl chromones (3a-i) is described. The interaction of 7-hydroxy-3-formyl chromone (1) with various substituted acetoph...
Surface mixing and biological activity in the four Eastern Boundary Upwelling Systems
Surface mixing biological activity four Eastern Boundary Upwelling Systems
2009/10/30
Eastern Boundary Upwelling Systems (EBUS) are characterized by a high productivity of plankton associated with large commercial fisheries, thus playing key biological and socio-economical roles. Since...
