We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...
Geostatistical methods were used to find efficient and accurate means for
salinity assessment using regionalized random variables and limited sampling. The
random variables selected, sodium absorption ratio (SAR), electrical conductivity
(EC), and clay content were measured on samples taken over an area of fifteen
square miles. Ordinary kriging and co-kriging...
The influence of polyphosphates upon the emulsification of
enzymatic hydrolyzates of casein and lactalbumin and upon salt-soluble
meat proteins was determined by a model system in which
oil-in-water emulsions were formed.
Sodium acid pyrophosphate, sodium tripolyphosphate and
sodium hexametaphosphate were mixed together in a weight ratio
of 4:2:4, respectively, to...
The work presented in this dissertation highlights the various techniques available to characterize the increasingly complex surfaces of engineered biomaterials. The methods used range from the simple measurement of a contact angle with a smartphone to a complex synchrotron technique like near edge x-ray absorption fine structure (NEXAFS) spectroscopy to...
n situ soil moisture monitoring networks are critical to the development of soil moisture remote sensing missions as well as agricultural and environmental management, weather forecasting, and many other endeavors. These in situ networks utilize a variety of sensors and installation practices, which confounds the development of a unified reference...
β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...
