The energy levels of internal waves observed during the
Arctic Internal Wave Experiment (AIWEX), conducted from the
drifting pack ice in the Beaufort Sea, increased as the speed of
the ice drift increased. The possibility of these waves being
generated by moving pack ice with a corrugated under-side is
explored...
Sustainable management of the world’s forests is a key component for conserving biodiversity, soil and water resources, mitigating climate change, strengthening economies, and promoting sustainable communities and human well-being, now and in the future. While international cooperation is important, the actual policies and management actions that affect forest conditions and...
Gas exchange, leaf area development, leaf anatomy and stomatal characteristics of four tall fescue selections differing in forage yield were examined to provide further insight into characteristics associated with yield differences of these selections. Winter-growing TFM 26 and TFM 16, the highest and lowest-yielding selections, respectively, and summer-growing selections TFK...
This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...
The Melnikov method is applied to a model of parametrically generated cross-waves in a long rectangular channel in order to determine if these cross-waves are chaotic. A great deal of preparation is involved in order to obtain a suitable form for the application of the Melnikov method. The Lagrangian for...
Sclerotinia sclerotiorum (causal agent of white mold) can cause serious economic losses in snap bean production as well as many other crops. Spores are produced in apothecia (mushroom-like structures) that develop from over-wintering sclerotia in the soil. Sclerotia are long-lived, durable hyphal survival structures produced by the fungus and they...
Since the early 1950's, the distribution of sediment at the
mouth of Redwood Creek has been altered by the effects of channel
aggradation and channelization along the lower reach. Severe flooding
in 1953, 1955, and 1964 caused bank erosion, landsliding, and
channel geometry changes along Redwood Creek. The increased sediment...
Fluctuating feeder cattle prices have a direct affect on the
revenue variability of feeder cattle producers. Hedging in the commodity
futures market is a marketing strategy which can, if properly used, reduce
the financial risk of feeder cattle producers. If the closing
basis value is known when a hedge is...
