Thirty preschoolers were tested for language skills using
the Preschool Language Scale (PLS), Peabody Picture Vocabulary
Test-Revised (PPVT-R) Form L, and Sequenced Inventory of Communication
Development (SICD). Each child's age scores on one test
were compared to his/her scores on the other two tests. As a
group, the children achieved...
A mathematical model of a differential thermal analysis (DTA)
system was formulated so that influence of the various physical parameters
on the DTA peak could be determined. The specific DTA apparatus
simulated had cylindrical sample holes drilled into a nickel
block considered to have a negligible thermal resistance, and the...
The first published notion that the j-function was in any way related to the Monster came in 1979, when Conway and Norton noted in [CN79] that each coefficient in the q- expansion of the j-function could be written as a (nontrivial) integral linear combination of the dimensions of irreducible representations...
Waste products from industry have often been disposed in
landfills without regard for any beneficial uses of the product in
agricultural production. This research was conducted to determine
the effect of a refractory metal processing waste product on (a) soil
chemical and physical properties, (b) perennial ryegrass forage
quality and...
Landslides are frequent in the steep forested regions of the Oregon
and Washington coastal mountain ranges. The need for forest products
has resulted in increasing logging activity in these marginally stable
areas. The occurrence of landslides has increased, which in turn has
focused greater interest in slope stability management.
Of...
Active habitat management plays a key role in the preservation of native ecosystems and rare species, especially in the Willamette Valley of Oregon, where natural succession to woodlands threatens the few wetland prairies remaining after 150 years of agriculture and urbanization. Sidalcea nelsoniana, listed as threatened under the federal Endangered...
