The central problem of this study was to construct and validate
an instrument to measure the complexity of the contexts in which student
teaching occurs and to use the instrument in the investigation of
factors related to context complexity and its effect on student teacher
performance.
The instrument to measure...
Increased sales of surimi seafood, with the majority as crabstick in the United States indicates that surimi based products are becoming more popular. With growing popularity, there is increased competition for market share. Under these circumstances, some companies may be willing to sacrifice product quality in order to facilitate manufacture...
Clay mineral genesis was studied in soils representative of several
different geomorphic surfaces in western Oregon, ranging in age from
Pliocene-early Pleistocene to late Pleistocene. Soil solution studies,
clay mineralogy, and soil raicromorphology were employed to provide
evidence of clay mineral synthesis and interpret soil genesis.
Soils at each study...
Rubus seed characteristics; seed coat morphology, anatomy, germination requirements and dormancy were studied in order to define protocols for breaking seed dormancy. Morphological analysis of the seed coat (testa) using scanning electron microscopy (SEM) included 56 seed accessions of 10 subgenera preserved in the collections of the US Department of...
The rate of the C¹⁴0₂ release from glucose, specifically labeled
with C¹⁴ at 1, 2, 3+4, and positions, was used to study the relative
participation of pathways of glucose catabolism in red beet slices.
Evidence was obtained which indicated that in mature red beets glucose
was catabolized mainly via glycolysis-tricarboxylic...
Four study sites were selected along an altitudinal gradient on Mt. Ashland in the Siskiyou Mountains of southern Oregon. The altitudinal gradient roughly corresponded to a gradient in temperature and water availability ranging from very hot and dry to cool and moist. Air and soil temperatures were continuously measured on...
