It is obvious to anyone who reads about or buys anything in the United States that we have a productivity problem. Losing our share of world markets, runaway inflation, high interest and unemployment rates are just a few of the symptoms. At Boise Cascade, we are very concerned about our...
This thesis provides the first general description of the natural variation in age
structure, growth rates, and survival in headwater populations of coastal cutthroat
trout Oncorhynchus clarkii clarkii from western Oregon, and a subsequent
synthesis of these life-history characteristics across the range of the subspecies.
Age, growth, and survival were...
As a major natural component of the extracellular matrix (ECM),
hyaluronic acid (HA) is an excellent choice for biomimetic, biocompatible
therapeutic materials. Furthermore, thiol-modified forms of HA are capable of
forming macroporous hydrogels that allow for both controlled cytokine release and
extensive vessel in-growth. It has previously been shown that...
The relation of bud and cambial activity to root initiation and
elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)
stem cuttings was studied through two successive growth cycles.
Stem cuttings of current season's growth were taken periodically
from field-grown Douglas-fir trees to determine: (1) origin and
development of root initials; and...
The thermal decomposition of tungsten hexacarbonyl was
investigated in an apparatus which allowed a solid sample of the material
to be sealed into a preheated batch reactor. Because the reaction occurs
with an increase in the number of moles of gas, it was possible to monitor
the progress of the...
Disentangling sediment source from sediment transport is a fundamental marine geologic challenge critical to the interpretation of any sedimentary record. The Eirik Ridge, a sediment drift south of Greenland, receives terrigenous sediment primarily from subglacial erosion of south Greenland’s Precambrian bedrock and Paleogene volcanics that outcrop in east Greenland and...
The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...
