Seabird guano is recognized as a powerful fertilizer and its entry into the intertidal zone of seabird breeding islands off the west coast of South Africa is hypothesized to cause enhanced intertidal algal production. Intertidal nutrient levels and algal production were measured monthly on the shores of seabird islands and on nearby mainland shores where no aggregabons of seabirds occur. The sh...

a labouring man, ast. 40, was brought to the Bristol Royal Infirmary at 11.30 on the morning of April 19th, with the history that for twelve months he had had a severe cough, had been losing flesh slightly, and on a few occasions had spat up a little blood. His condition had never before been in any way critical, and up to the day previous to admission he had been doing his work regularly. Abou...

There is a great demand for statist ical modeling of phenomena tha t evolve in bo th space and time. Practical examples are those in Haslett and Raf tery (1989), Handcock and Wallis (1994), Cressie and Huang (1999), Brix and Diggle (2001), Stroud et al. (2001), De Iaco et al. (2002), Gneit ing (2002), and Hartfield and Gunst (2003), to mention but a few. Two commonly used tools to describe the ...

A Normal Mode Analysis (NMA) of the Chesapeake Bay was performed using Neumann boundary conditions and COMSOL MultiPhysics (formerly known as FEMLAB). The lowest 100 eigenstates were calculated and compared to a finite difference solution. Based on the normal modes derived numerically, surface current vector fields can be calculated. The vector fields of the Chesapeake Bay provide tools for the...
