A procedure for evaluating the precision of atomic absorption
measurements is presented and applied to 21 elements under varying
instrumental conditions. The experimental relative standard deviations
(RSD's) in absorbance obtained from repetitive measurements made
with a high resolution voltmeter and on-line computer, are compared
to those predicted by a recently...
Mount Sinabung, Sumatra, Indonesia initiated eruptive activity in 2010 with the addition of a magmatic component in 2013, after a 3 year period of quiescence. Observations of magmatic activity began with phreatomagmatic eruption starting July 2013 closely followed by extrusion of andesitic lava in December 2013. Lava effusion has persisted...
In recent years, participation in outdoor recreation has increased, with nearly half of Americans partaking annually (Thomsen, Powell, & Monz, 2018). The goal of recreation management is to provide diverse opportunities for leisure services through preservation of parks, open space, recreational facilities, and programs for park visitors. Management activities can...

Hybrid electric vehicles (HEV’s) are a very important part of today’s transportation system as they are bridging the gap between fully electric vehicles and conventional internal combustion vehicles (ICV’s). They have much higher efficiencies and lower emissions than ICV’s, while still having the ability to travel long range and refuel...
It is the purpose of this thesis to present a course of study in
general "Power Mechanics" which would enable the junior high school student
to understand the elementary principles of power generation and distribution,
and to appreciate the relationships of the use of power to our social order.
The...
The identification of sources of point and nonpoint fecal pollution is difficult to determine. Understanding the sources of fecal organisms in quality limited waters could greatly enhance our ability to restore and protect the water quality and habitat of these systems. Antibiotic resistance patterns of fecal streptococci bacteria were analyzed...
An Internet Map Server (IMS) web site was constructed with the goal of
helping middle- through high-school students learn about ocean processes. This IMS was
developed in conjunction with the activities of the Science & Math Investigative
Learning Experience (SMILE) program, and for eventual use with the Oregon Coastal
Atlas,...
