Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
In the U.S. there are increasing energy demands that require an ever-increasing need for the large-scale use of new energy resources. Specifically, sporadic renewable energy sources are being incorporated into utility energy portfolios. Thus, supporting stationary energy storage technologies are needed to make these renewable sources reliable and feasible for...
The photochemistry of some analogs of insect growth regulators
(IGR's) was studied. Methyl geranate, TY, was synthesized and the
mechanisms of its photochemical reaction pathways were studied by a
variety of techniques. Direct irradiation of 71 in ether leads to the
formation of five new products: 98, the product of...
Curbing overall disease burden with faster intervention requires early stage and accurate diagnostics. Ultrasound (US) provides a safe, nonionizing, inexpensive, and noninvasive imaging modality that has become commonplace in diagnostics. Paired with the relatively new technology of photoacoustic imaging (PAI), optical level resolution becomes feasible with the deeper signal penetration...
Fishermen's and managers' perceptions of fishery issues are an
important factor to consider when studying conflicts between the
two groups. According to theories of conflict management,
differences in perceptions may cause situations to be characterized
by misunderstanding and mistrust, and may add to the difficulties in
managing the conflict.
A...
The diffusion of livestock guarding dogs into American agriculture provides an example of a developed nation adopting a peasant husbandry practice. Guarding dogs, associated with transhumant husbandry, have been used to protect sheep and other livestock from predators in Eurasia for 2000 years. However, they were virtually unknown by Anglo-American...
Stocks of salmon are declining in the Pacific Northwest. Based on region-wide studies that list and categorize the status of salmon stocks (Nehlsen et al., 1991; Huntington et al., 1994; and Nawa, 1995), I analyze the watersheds where stocks of salmon spawn for several anthropogenic variables, most of which are...
The relative accuracy of solutions to chaotic systems was examined using the Lorenz
system as a case study. The classical fourth order Runge-Kutta method was employed to
generate solutions using various step sizes, and the resultant solutions were compared. A
second set of solutions was then computed using one of...
Background: Early and repeated patient–provider conversations about advance care planning (ACP) are now widely recommended. We sought to characterize barriers and strategies for realizing an iterative model of ACP patient–provider communication.
Methods: A total of 2 multidisciplinary focus groups and 3 semistructured interviews with 20 providers at a large Veterans...
A vital safety concern in the analysis of nuclear power reactors
is the thermal hydraulic behavior of the reactor coolant system
under steady state and transient conditions. The goal of this
study has been to develop an appropriate model for the U-tube type
steam generators in a typical pressurized water...
