Sediment storage in and release from the Granite Creek catchment over Holocene timescales is modulated by the fluctuations of Tana Glacier, which periodically blocks the outlet of Granite Creek. Little Ice Age expansion from 1500-1900 AD is suggested by lichenometric ages of alpine glacial moraines within Granite Creek valley. Trimlines...
The majority of research in environmental education (EE) has focused on measuring knowledge, attitudes, and behavior using quantitative tools and methods. Few studies have attempted to elicit and characterize children's conceptions of the environment or nature, particularly those resulting from a residential EE experience, which contextualize knowledge, attitudes, and may...
A study of phosphorus loading and water quality implications was conducted for
the Oregon coastal lakes. The study was based on existing data for lake total phosphorus
concentrations and for watershed land uses. A phosphorus mass-balance model was
developed to predict lake total phosphorus concentrations from estimated phosphorus
loading from...
This study examined the dynamics of student, teaching assistant (TA), and faculty learning in relationship to implementation of a genetic technologies project in a university introductory biology course. Research focused on the types of learning that occurred and the various factors impacting that learning. Study participants included 25 undergraduate non-science...
A procedure is described for analyzing the nitrogen content of
durable press cotton fabric at the rate of 20 samples per hour using
the Technicon Kjeldahl Auto Analyzer equipped with a continuous
digestor. This method was as good as or better than conventional
micro -Kjeldahl technique s.
Durable press cotton...
This report presents a refined method for the calculation of fuel centerline temperatures and the linear-heat-rating-to-incipient melting, ' Q'[subscript m], of mixed-oxide fuel typical of that to be used in the Fast Flux Test Facility and in Liquid Metal Fast Breeder Reactors. Of primary concern are the effects of the...
