Halyomorpha halys (brown marmorated stink bug, Hemiptera: Pentatomidae), an invasive insect pest, has established populations in the Willamette Valley of Oregon. Halyomorpha halys is a potential pest of many specialty crops in the Willamette Valley, including hazelnuts (Corylus avellana L.). The objectives of this study were to 1) characterize the...
BACKGROUND: Oregon produces 99% of the hazelnuts grown in the United States. The key pest threatening commercial hazelnut orchards in Oregon is
Cydia latiferreana (Tortricidae), filbertworm moth (FBW). Currently, most growers control FBW with one to two applications of esfenvalerate (Asana XL), a broad spectrum pyrethroid. Pheromone mating disruption is...

Physical modelling is instrumental to the progression of coastal engineering research and our understanding of the offshore and nearshore environments. Scaled models are designed and built to be tested in coastal research laboratories, where a wave basin or flume generates the desired wave conditions for experimentation. The surrounding hydrodynamics of...
Non-starter lactic acid bacteria (NSLAB) are found at low levels in fresh raw milk and are important to the dairy industry because of their potential impact on the flavor and texture of yogurt, sour cream, and cheese. The purpose of this study was to evaluate three methods for the identification...
The properties of (1-x)BaTiO3-xBi(Mg1/2Ti1/2)O3 (BT-BMT) ceramics were fabricated from reagent-grade ceramic powders by solid-state methods and investigated for solubility, relative permittivity, dielectric loss, polarization, and electromechanical strain. The solubility limit was found to be between x = 0.3 and 0.4. Ba-deficient samples were fabricated, corresponding to stable single-phase compositions; these...
Plasma membranes isolated from a yeast sterol auxotroph (RD5-R)
grown on 1,5, and 15 pg m1⁻¹ exogenous concentrations of sterol showed
no discontinuity in plots of steady-state fluorescence anisotropy.
Liposomes constructed from phospholipid and sterol extracted from RD5-R
grown on different sterols indicated exogenously supplied sterol
modulated cellular phospholipids such...
