The technique of freeze branding was developed by Dr. R. K. Farrell during the 1960’s as an alternative to fire branding domestic livestock. Today, freeze branding is internationally used for cattle and horse identification. In addition to many species of haired animals successfully freeze branded non-haired animals such as whales,...
Lumber drying accounts for about 70 percent of sawmill energy
requirements. Significant recovery of energy used to dry lumber
would result in significant energy recovery for the mill. This is
desirable because of today's high cost of energy. The objective of
this study was to recover some of the energy...
The goal of this study was to evaluate the ability of two seedling quality evaluation methods to predict the field survival of Douglas-fir (Pseudotsuga menziesii) seedlings. The starch reserves in seedlings have been suggested as a possible predictor of seedling quality. Starch reserves have been shown to decrease during cold...
Sediment yield increases following timber harvest and road construction
were predicted for four Pacific Northwest experimental
watersheds. Sediment yields were predicted using a handbook developed
by the U.S. Forest Service entitled, "An Approach to Water Resources
Evaluation of Non-Point Silvicultural Sources" (WRENS). Predicted
sediment yield increases varied from 40 to...
A PID controller was designed to control the performance of an oil-heated fractal-like branching microchannel desorber for use in an ammonia-absorption refrigeration system. Both the amount and concentration of ammonia refrigerant generated at the desorber can be controlled by choosing the rectified circulation ratio as the controlled variable in a...
This document provides the abbreviated program grid showing a one-page summary of presentations made at the NAAFE Forum 2015, Economic Sustainability, Fishing Communities, and Working Waterfronts, held in Ketchikan, Alaska, May 20-22, 2015. The conference was organized by Keith Criddle and Quentin Fong, University of Alaska Fairbanks, School of Fisheries...
Despite their apparent economic benefits to harvesters, Individual Fishing Quotas (IFQs) have only been adopted in three U.S. fisheries: Mid-Atlantic surf clam and ocean quahog; South Atlantic wreckfish; and, North Pacific halibut and sablefish. During the 1996 reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act, Congress temporarily blocked implementation...
Satellite ocean color data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) were used to examine distributions of chlorophyll concentration within the Southern Ocean for the period of October 1997 through September 1998. Over most of the Southern Ocean, mean chlorophyll concentrations remained quite low (<0.3-0.4 mg m¯³). Phytoplankton blooms where...
The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...
