Flat, laminar, premixed hydrocarbon-air flames were stabilized
on a porous-plate burner. In addition to temperature profiles,
concentration profiles were measured for methane, ethane, ethylene,
propane, acetylene, propylene, carbon monoxide, carbon dioxide and
oxides of nitrogen. Dead space thickness, luminous flame zone
thickness and hydrocarbon disappearance point responses were also
monitored....
This study describes the surface configuration of
Goodhue County and attempts to determine the origin of that
configuration. The research has a descriptive portion--an
objective examination of land surface configuration and the
composition and distribution of rock material underlying
that surface, and a theoretical portion--a speculative
examination of the factors...
The sinuous flight behavior of male Douglas-fir tussock
moths, Orgyia pseudotsugata, (McD.), is characterized by
positive anemotaxis and positive chemoklinotaxis and varies
depending on distance from the pheromone source, population
density, and time of day. Visual cues play a minor role
in close-range orientation to a pheromone source, but
males...
There has been an increased interest in the
quantification of pattern in ecological systems over the past
years. This interest is motivated by the desire to construct
valid models which extend across many scales. Spatial methods
must quantify pattern, discriminate types of pattern, and
relate hierarchical phenomena across scales. Wavelet...
