Many devices and methods for radiological searches are currently being developed, including scanning using simple detectors, mapping using large-volume detectors, and Compton imaging using 3-D position sensitive detectors. However, these devices are typically expensive and the methods used require long periods of time to generate a direction or location. The...

Disasters result from hazards affecting vulnerable people. Most disasters research by anthropologists focuses on vulnerability; this article focuses on natural hazards. We use the case of wildfire mitigation on United States Forest Service lands in the northwestern United States to examine social, political, and economic variables at multiple scales that...
The project focuses on nonequilibrium ecosystem dynamics, a body of scientific research that characterizes and interprets ecosystem change. INR summarizes knowledge from this field, describes ways in which the current management framework may be inconsistent with scientific findings, and helps identify options for future management. This paper is designed to...
This publication recommends management practices for controlling diseases and insects. This pest management guide was prepared for the home gardener. It doesn’t meet the exacting requirements of the commercial fruit grower. Many fungicides and insecticides are available, which, when used according to the label directions, are effective in managing diseases...

Controlled flow reductions of 75% apportioned over
four two-week intervals were studied during the summers of
1975 and 1976 on the North Fork of Elk Creek, an Oregon
coastal stream. The effects of reduced flows on invertebrate
drift, insect benthos, and the available food for
juvenile salmonids were measured.
Invertebrate...

Autoinduction (AI), the response to self-produced chemical signals,
is widespread in the bacterial world. This process controls
vastly different target functions, such as luminescence, nutrient
acquisition, and biofilm formation, in different ways and integrates
additional environmental and physiological cues. This diversity
raises questions about unifying principles that underlie all

The prevalence of Internet-of-Things (IoT) applications leads to an increasing focus on the design and optimization of sensor nodes. Battery lifetime and associated costs of battery replacement often limits the long term operation and viability of sensor nodes. RF wireless energy harvesting on the other hand can be appealing since...

Aggregation and species association of 9 species of phytophagous and
predaceous mites were studied for 6 yr in an orchard with 100, 2 m tall 'Red

powerful, and easily interpreted. It relates the proportion of habitat occupied to...
Liriomyza sativae and L. trifolii (Diptera: Agromyzidae) are two highly invasive species of leafmining flies, which have become established as pests of horticultural crops throughout the world. In certain regions where both species have been introduced, L. sativae has displaced L. trifolii, whereas the opposite has occurred in other regions....

The influence of oil sprays on the field spread of the aphid-borne
bean yellow mosaic virus (BYMV) in bean was studied in 1972
and 1973. Oil sprays failed to significantly reduce virus spread in
the 1972 BYMV experiment. However, the data did suggest that the
efficiency of the oil sprays...
