Six years of Nimbus-7 Scanning Multichannel Microwave
Radiometer (SMMR) data from 1979 to 1984 are recalibrated
at the radiometric level. New statistical techniques are
developed to quantify the temporal and orbital data errors
and to generate numerical corrections for brightness temperatures
prior to estimation of geophysical parameters.
The foundations of...
This thesis examines archaeological material in order to explore gender and ethnicity issues concerning fur trade era families from a settlement in the Willamette Valley, Oregon. Ethnohistorical information consisting of traders journals and travelers observations, as well as documentation from the Hudson's Bay Company, Catholic church records, and genealogical information...
Calanoid copepod diet was investigated in Oregon coastal waters to determine
the trophic significance of phagotrophic protists as copepod prey within an ecosystem
where the microplankton biomass is typically dominated by large diatoms. Prior to and
during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic
ciliates were measured...
The major purpose of the study was to determine whether
science process achievement tests could be developed for administration
to groups of primary grade students. Six Basic Science Process
Tests (BSPT) were constructed as samples of the format proposed.
Each BSPT was designed to assess one of the basic science...
The energy absorbed by microscopic volumes exposed to ionizing
radiation is not well represented by the average dose due to the small
number of discrete energy transfers involved. The energy deposited in
a microscopic volume can be determined by measuring the ionization in
a detector filled with gas at low...
Most existing methods for generating individual task time estimates in production systems where jobs move through various manually operated workstations remain tedious and time consuming. For existing systems, average task times may vary considerably from prior estimates causing system inefficiencies, poor scheduling and poor planning decisions. Accurate and up-to-date estimates...
Training is a key business process used to increase the skills and knowledge of employees in an effort to improve overall performance. Evaluation of the effectiveness and efficiency of training processes is necessary to ensure time, money, and resources are used to provide the most benefit possible. This investigation is...
Jalapeño peppers are usually consumed raw and fresh with minimal processing. They
contain antioxidants and bioactive compounds which are of human health benefits.
There have been an increasing number of reports of foodborne outbreaks attributed to
inaccessibility of sanitizers to Salmonella , E.coli and Listeria monocytogenes when
embedded in fruit...
This research investigates the physiological and transcriptional responses of Nitrosomonas europaea when exposed to chlorinated aromatic compounds and heavy metals under varying environmental conditions. It was found that transcriptional responses of identified sentinel genes correlate well with nitrification inhibition. Sorption of metals to biomass was also investigated and found not...
