Microbial populations associated with the major substrates of the
canopy of a 70 m old-growth Douglas fir were studied to determine
potential activities. Seasonal samples from bark, foliage, epiphytic
moss, lichens, and litter accumulations were collected to i) obtain
population data, ii) to isolate the major groups of microorganisms
present,...
This study investigated the practices public and academic
library administrators find useful and utilize in analyzing

seventy thousand who survive are left with such
intellectual impairment as to preclude returning to a
normal life. The purpose of this study is to
investigate the...
Previous research has shown a gap between chemistry students' conceptual
and computational understandings of chemistry topics such as gas laws,
equilibrium, and reactions. This qualitative study examined the conceptual and
computational understandings of stoichiometry of college students enrolled in a
large lecture Introductory Chemistry course. Factors that might influence students'...

A photographic band-ratioing technique was investigated.
The data source consisted of 70 mm Landsat Multispectral Scanner
(MSS) negatives. The process would require combining registered
positive and negative transparencies to achieve a ratio
modulation in the resulting print. This would also require
compensation for atmospheric effects on the original negatives by...
