This thesis involves the interpretation of gravity and other
potential field anomalies caused by layers of varying thickness. The
partial differential equations of potential field theory are reviewed for
gravitational and magnetic force fields. A similar review is carried
out for steady-state heat transport and diffusion processes. For the
gravitational...
The number of sawmills in the coastal lumber-producing area
of British Columbia diminished from 364 In 1955 to 162 in 1968. In
the interior of the province the reduction in plant numbers was from
2125 to 740. Over the same period lumber production in the province
increased from 4.9 billion...
