We study the stability properties of, and the phase error present in, a finite element scheme for Maxwell’s
equations coupled with a Debye or Lorentz polarization model. In one dimension we consider a second order
formulation for the electric field with an ordinary differential equation for the electric polarization added...

In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft and surface-based equipment were based on Cape Verde's islands, helping to fill some of the data void between Africa and the Caribbean....
Accurate assessment of specific mortality factors is vital to prioritize recovery actions for threatened and
endangered species. For decades, tag recovery methods have been used to estimate fish mortality due to avian
predation. Predation probabilities derived from fish tag recoveries on piscivorous waterbird colonies typically
reflect minimum estimates of predation...

Internally recording instruments were installed in the Drake Passage in January 1979 and recovered in January 1980. Additional instruments were installed at this time for the first experiment in the Pilot Ocean Monitoring Experiment. These are to be recovered in March of 1981. The array consisted of seventy current meters...
The objective of this research was to investigate
the physiological effects of body posture on cycling.
The familiar positions of bicycle riding have been the
touring posture (hands stretched on top handlebar) and
the racing posture (hands bent at the elbow, with the
back horizontal). However, a relatively new stance...
This paper presents an application of the wave equation to the
problem of selecting a driving hammer for prestressed concrete piles.
The potentially damaging effects of these types of hammers on various
prestressed concrete piles were analyzed by means of parametric
studies carried out on a hypothetical group of problems...
The work described herein details the synthesis and application of
biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents
on the aryl ring of the terminal acetylenic carbon. From this work, we
successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps
from inexpensive commercially...
One of the important ‘hallmarks’ of cancer is angiogenesis, which is the process of formation of new blood vessels that are necessary for tumor expansion, invasion and metastasis. Under normal physiological conditions, angiogenesis is well balanced and controlled by endogenous proangiogenic factors and antiangiogenic factors. However, factors produced by cancer...
