Basalts of both Eocene and Miocene age from several groups
along the Oregon and Washington coasts have been analyzed for some
major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed
in these samples are used for comparisons within the groups studied...
The atmospheric trace element abundances associated with slash
burning have been measured by instrumental neutron activation analysis
(INAA). On site ground level samples were collected during the slash
burning season using high volume samplers and a cascade impactor. In
addition to the air samples, soil, wood and ashed wood samples...
Six experiments were carried out with Single Comb White Leghorn laying chickens to
assess the effect of feeding a source of direct-fed microbials (Lactobacillus; Lacto) and its
carrier [condensed cane molasses solubles (CCMS)] on the retentions of fat, nitrogen and
several minerals; on the status of the pH of the...
This dissertation presents the findings of a literature review and information
regarding selection, implementation and development of a chemical composition
procedure for asphalt cements. The chemical composition analysis selected was
the Corbett-Swarbrick procedure standarized as ASTM D4124. The procedure is
a selective adsorption / desorption (solid / liquid) chromatography which...
The assumption of constant quartz accumulation for the deep-sea
sediment core Y69-106P, taken in the Panama Basin, has been
used to date the core and construct a sedimentation rate versus time
curve for it. Stratigraphic control for the calculated time scale
includes three carbon-14 measurements, the extinction of the
radiolarian...
Interest in nanomaterials is motivated partly by their potential for sensor arrays to detect
different gases. Nanowires in particular are of interest because their high surface-to-volume
ratio promises the possibility of high sensitivity. However, because of their discrete
quasi-one-dimensional geometry, electrical integration of nanowires into photolithographically
defined devices and circuits...
Understanding the effects of climate variability on growth dynamics and timing of early life history events in marine fishes can provide insights into survival, recruitment and productivity. Field collections (2005, 2007, 2009-2011) were combined with otolith microstructural analysis to examine interannual variation in larval and juvenile growth rates, size at...
In recent years, integrated circuit technology has
spawned the development of many low cost and high performance
microprocessors and microcontrollers. With these devices,
there is an increasing interest in the implementation of
distributed control networks, utilizing microprocessors in the
control nodes.
In this work, a low-cost liquid crystal display (LCD)...
E8,E10-dodecadien-1-ol, the primary component of the female sex pheromone of codling moth, Cydia pomonella L., has no attraction to male Oriental fruit moth (OFM), C. molesta (Busck). However, this compound when added to the OFM pheromone blend of Z8-dodecenyl acetate (85.5%), E8-dodecenyl acetate (5.5%), and Z8- dodecen -1 -ol (9.0%),...
Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...
