Subsurface inputs into lotic systems are a primary mechanism for cooling streams with high ambient water temperatures. Objectives of this study include: 1) to determine the effectiveness of Forward Looking Infrared (FLIR) thermal imagery to detect shallow
aquifers, 2) to characterize certain physical, spatial, and temporal characteristics of the fluvial,...
This manual provides guidance on creating subject heading proposals for Indigenous topics that can be submitted to the Subject Authority Cooperative Program (SACO) for addition to the Library of Congress Subject Headings.
The heat inactivation of the psychrophilic marine bacterium,
Ant-300, was investigated in terms of permeability control, glucose
uptake, and respiration. Extensive leakage of 14C-cellular material
occurred at 13 C, the maximum growth temperature of the organism.
Protein and RNA were released from the cells in significant
quantities. Inhibition of glucose...
Annual applications of fresh or composted dairy manure were assessed for their effects on root rots of sweet corn and snap bean and damping-off of cucumber in a field soil. Soil biological and physical properties were measured as possible indicators of root rot suppressive potential. Regardless of amendment type or...
This qualitative narrative inquiry study explored the experiences and perspectives of five Asian American females who have sought presidencies and/or vice presidencies in community colleges. All five of the participants are currently either a president or vice president in community colleges. This study found nine themes that capture the barriers...
The transmission of strawberry mottle virus (SMV) to Fragaria vesca
L. by Chaetosiphon thomasi and C. fragaefolii was studied to determine
differences between the two species. Acquisition, inoculation, and
retention phases of transmission were described. In all phases, C.
fragaefolii was found to be the more efficient vector.
Mean transmission...
Two types of exogenous mortality factors, density-independent and density-dependent, were identified for the black vine weevil, Otiorhynchus sulcatus Fab., developing on container grown rhododendrons. The addition of the insecticide acephate, (O.S.- Dimethyl acetylphosphoramidothioate, Orthene®)75S) to the rhizosphere of rhododendrons in which larval O. sulcatus develop was categorized as a density-independent...
The life history of the Obscure Root Weevil, Sciopithes obscurus (Horn), on Rhododendron was studied at four sites in the Willamette Valley. This research was conducted in an effort to provide information necessary to develop adequate methods to control this Curculionid pest on Rhododendron in the Willamette Valley. Five larval...
The relationship between pea enation mosaic virus
(PEMV) and aging pea aphids was studied. Although this
research initially emphasized the relationship between the
decline in the rate of PEMV transmission and the 'concentration
of PEMV within pea aphids, aphid age was found to be
the principle factor influencing transmission. Enzymelinked...
