Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...
Bioassays of acetone extracts from xylem tissue in tomato stems
and corresponding reductions in Fusarium oxysporum f.sp. lycopersici
race 1 or 2 populations within the stems suggest that fungitoxic
materials within the xylem vessels of Bonny Best, Jefferson, and Marglobe
tomato cultivars initially kill a portion of the inoculum conidia....
Soil samples from the Mazama tephra deposit were collected
from the AC and C2 horizons at five different locations along the axis
of the main depositional lobe. The clay fraction from the samples
was recovered and studied by means of chemical, x-ray, DTA and
electron microscopy methods in order to...
This study determined the independent effects of various homogenization cycles and
precipitation treatments on the elevated temperature workability and the final ambient
temperature mechanical properties of AA2024 aluminum alloy and on the T3 tensile
properties of 2014 aluminum alloy as well as T6 tensile properties of 2618 and 2618 (Curich)...
The effects of broadcast gypsum on infiltration rates, crusting,
aggregate stability, and runoff and sediment yields were analyzed
during the winter months on three West Oregon soils. The results were
used to evaluate its utility as a management tool to help control
erosion.
An application rate of two metric tons...
Douglas-fir utility poles are routinely air seasoned before
treatment with chemical preservatives. Basidiomycetous fungi invade
these poles and may cause strength loss during air seasoning or later
if treatment temperatures are insufficient to kill the decay fungi.
The purpose of this study was to develop a rapid test to asses...
