With the advent of underground testing, the study of the propagation of seismic signals has become of great importance. This
thesis investigates the design of electrical analogs to represent the
propagation of seismic waves.
The analogs developed...

An algorithm is described for determining the vertices
and supporting planes (or lines) of the convex hull
of a given set of N distinct points in 3-space. The
method involves determining a finite sequence of convex
hulls, each successive convex...

The effect of competition on the brood survival of the Douglas fir
beetle Dendroctonus pseudotsugae Hopkins, in down or windthrown
Douglas-fir Pseudotsuga menziesii (Mirb.) Franco was studied in the
field and the laboratory. The investigation of...

A new method for determining ion exchange equilibrium
data by liquid scintillation counting of the equilibrated solution
phase is described. This method has been applied to determine
equilibria between Dowex 50W X8, a commercial strong cation...

The mechanical properties of materials at cryogenic temperatures
have been the subject of increasing interest during the past few
years, although very little actual materials testing has been done at
extremely low temperatures because of the high...

A quantitative comparison was made of the incorporation of
14, C¹⁴ lipid compounds into Lee influenza virus. The compounds
tested were either lipids reported to be present in the virus or precursors
to virus lipid components. Infected...
