One of the most promising methods of constructing bandpass
filters without inductors is the RC digital filter. It is simply a number
of parallel RC branches which are sequentially switched between
the source and the load. If the source signal is at the same frequency
as the switching rate of...
Trace metals in the aquatic environment are generally concentrated
on the surface of solid geochemical phases which eventually become incorporated
into estuarine and marine sediments. The mechanism of trace
metal concentration is believed to be adsorption with various geochemical
phases such as hydrous metal oxides, clays, and organic matter.
Metals...

subsamples were collected and analyzed for organic carbon...
Several physical and chemical characteristics of sediments have
been proposed for use in tiered testing plans to predict the
presence of trace metals in estuarine sediments. Correlations often
exist, but the mere presence of a trace metal does not indicate
toxicity; a more thorough approach is needed.

I experimentally test the hypothesis that the potential for selfing
increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible,
profusely-flowering perennial. This follows from the
premises that 1) pollen dispersal by pollinators between flowers is
limited, and 2) individual pollinators, in this study bumblebees, will
visit more flowers per...
