This history concerns the scientific contributions of Charles
Babbage (1791-1871) to mathematics, to the invention of calculating
machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself

addresses given by Father Charles Edward Coughlin. He devoted his career to

In recent years, however, it adopted log export restrictions as a hedge against the rapid depletion of its timber resources. Although conducted independently, its ASEAN partners (Malaysia and Indonesia), have likewise instituted similar restrictions on their own...
Monthly samples of nutrients, phytoplankton and zooplankton
were taken in the Columbia River estuary over a period of 16 months
in order to determine distribution with season and salinity, and interrelationships
between plankton and nutrients.
Nitrate and phosphate levels in the river water entering the
estuary are high in the...
A study has been made of the vertical distributions and
migrations of a large number of zooplankton species at Weather
Station "P" in the Subarctic Pacific. Simultaneously towed horizontal
opening-closing nets were used for the study. The distributions
and migrations of 104 taxa have been subjectively grouped
into seven basic...
The ~5 km3, 4.54 to 4.09 Ma Caspana Ignimbrite of the Altiplano-Puna Volcanic Complex (APVC) of the Central Andes records the eruption of an andesite and two distinct rhyolitic magmas. It provides a unique opportunity to investigate the production of silicic magmas in a continental arc flare-up, where small volumes...
Physical, chemical and bacterial water quality parameters of
the upper Wallowa River were sampled periodically between July 2,
1978 and June 9, 1979 at nine stream and lake sampling sites. Water
upstream from Wallowa Lake was typified by low nutrient concentrations
( generally below detectable limits except for nitrates), low....
