In this paper we present a model of Non-Euclidean geometry
in three dimensions. This will show that the axioms of Non-Euclidean
geometry are consistent if Euclidean geometry and, hence, arithmetic
is consistent. However, the model is incomplete for we have not
included the topic of congruence, the axiom of Archimedes,...
Environmental education programs seek to foster an appreciation for the natural world while introducing students to scientific thinking. Citizen science engages non-scientists in the systematic collection and analysis of data. The Betts Forest Landscape Ecology Lab combines both goals by inviting teachers in Corvallis, Oregon, and surrounding areas to participate...
Aligning Real-Time Networks (RTNs) with the National Spatial Reference System (NSRS) is crucial to ensure accuracy, consistency, interoperability, and long-term data integrity for geospatial applications. However, the effectiveness of different alignment methods as well as the need for monitoring approaches to maintain alignment consistency with the NSRS have not yet...
Five boron rates and seven water levels were applied
to bush green beans (Phaseolus vulqaris cv Oregon 91G) and
to cauliflower (Brassica olereacea var. botrytis, cultivar
"Snowball Y") in 1989 and 1990 to evaluate their effects on
total yield of both crops and on outer quality, head
hollowness and internal...
This study involved three separate experiments employing a total
of 29 horses and 4 rabbits. The purpose of these studies was to investigate
the use of various quantities and forms of ryegrass straw in horse
rations, and to determine the use of whole corn plant pellets as an alternative
roughage...
Air traffic flow management over the U.S. airpsace is a difficult problem. Current management approaches lead to hundreds of thousands of hours of delay, costing billions of dollars annually. Weather and airport conditions may instigate this delay, but routing decisions balancing delay with congestion contribute significantly to the propagation of...
Over 1,000 9th and 10th grade male high school youth in the
Country of Belize, Central America, were administered the AAHPER
Youth Fitness test during the 1972-73 academic school year. Results
were analyzed and compared to similar data in the United States. Of
41 comparisons utilizing the Student t for...
