The fertilizer value of anaerobically-digested, dewatered biosolids in dryland cereal cropping systems was evaluated at six locations in central and eastern Washington (25 to 35 cm annual precipitation zone). Biosolids were applied at rates of 3 to 20 Mg/ha (approximately 150 to 900 kg N/ha). We measured increases in soil...
Land managers are increasingly turning to a new tool for visually depicting, analyzing, and communicating the technical aspects of forestry, specifically in the area of timber harvest and unit design. This tool is computer-based image editing software. In the 1980's, it was referred to as image capture technology, or ICT....
Aerial videography in combination with GPS were used to monitor the
active surge of Alaska's Bering Glacier. The large aerial extent of the study area and the
unpredictable weather in coastal Alaska required innovative techniques to be used in
order to successfully monitor the surge environment. A portable aerial videographic...

National and international organizations are developing spatial databases to assess the
distribution of Biodiversity using geographic information systems (GIS). Currently, there
are no guidelines or standards for building GIS databases for biodiversity assessment
because database design is discipline-dependent and most biodiversity disciplines lack
spatial traditions. The present research analyzes the...
This paper surveys sequential and parallel implementation techniques for functional programming languages, as well as optimizations that can improve their performance. Sequential implementations have evolved from simple interpreters to sophisticated super-combinator-based compilers, while most parallel implementations have explored a broad range of techniques. We analyze the purpose and function of...
Multiparadigm programming languages have been envisioned as a vehicle for constructing large and complex heterogeneous systems, such as a stock market exchange or a telecommunications network. General-purpose multiparadigm languages, as opposed to hybrid multiparadigm languages, embody several prevalent programming paradigms without being motivated by a single problem. One such language...
A layered model of steady geostrophic ocean circulation driven by wind stress and buoyancy flux at the surface is derived. Potential vorticity, or thickness, of the two near-surface layers is driven by Ekman pumping and buoyancy pumping. The latter is represented as a flow of mass proportional to the modified...
Laboratory soil tests will help you develop
and maintain more productive soil and
increase crop production by providing
information on the available nutrient content of
your soil. Soil testing helps you select the
correct kind and amount of fertilizer and liming
material. Recommendations are based on the
results of fertilizer...
