Increasing demands on earth resources require the need to
know how much resource is present. A new technology, which is
developing partially with the support of the National Aeronautics and
Space Administration, will help to inventory and monitor surface resources
in a more comprehensive manner than previously possible.

Uptake and cycling of nitrogen (N) in mature trees are not well understood.
Fertilizer-N uptake, partitioning, and use-efficiency were studied in standard strain
'Topred Delicious' and spur strain 'Redspur Delicious' mature apple trees {Malus
domestica Borck) on 'Malling 7A' (M.7A) rootstocks. The treatments consisted of a
ground application in spring,...
Softwood plywood is one of the structural wood products studied in the CORRIM
II effort to document the environmental performance of wood product in residential
structures. Life-cycle inventory (LCI) models were developed to provide performance
data for plywood production by tracking all of its inputs and outputs in a gate-to-gate...
The use of electronic cigarettes (often referred to as vapes or e-cigs) has grown rapidly in the past decade. While these devices may not deliver the same level of carcinogens and toxicants as combustible cigarettes, they can deliver nicotine (a known developmental toxicant) as efficiently. Previous work suggests that, during...
The Teledyne Wah Chang facility is a manufacturer of the rare metal zirconium. The facility has been in constant production since 1956. In 1973 an attempt to utilize different sand ore sources from Nigeria and India in a new carbiding process, prior to chlorination, failed. The resulting byproducts of the...
The Hampton Tuff is a 3.9 ± .02 Ma (2σ) ignimbrite sheet from the High Lava Plains of central Oregon. The majority of known outcrops exist to the north, within ~22 mi (~35 km) of the Frederick Butte Volcanic Center, the proposed source of the tuff. Thickness of the tuff...
I offer a personal and prehistoric exploration of the concept of immanence, the principle of a divine force living, remaining, and operating within living creatures, inherent in the human, including the female; a unifying force that connects humans to each other, to nature, and to the earth. I examine the...
Consumers are increasingly turning to farm direct foods for personal reasons, such as fresh and healthy food, and for public reasons, such as supporting local and rural economies and reducing the environmental impact of their food choices. As a result, farmers’ markets and other direct farm marketing has increased substantially...
