Radiotracer methodology in biological science

Creator:: Willis, David L.
Abstract:: The use of radioactive isotopes as tracers in biological systems has become widespread since the close of World War II. Proper use of radiotracers requires a fundamental understanding of the physical nature of radioactivity, the characteristics of ionizing radiation, and the various methods available for measuring radioactivity. More importantly, the...

A review of the deep water Liparidae from the coast of Oregon and adjacent waters

Creator:: Stein, David L.
Abstract:: Descriptions and distributions are given of 28 species of Liparidae occurring or possibly occurring below 200 m between San Francisco and northern Vancouver Island, with keys for their identifications. Nine genera are included: Careproctus, Elassodiscus, Lipariscus, Nectoliparis, Rhinoliparis, Acantholiparis, Paraliparis, and two new genera are described, Odontoliparis and Osteodiscus. Eight...

Environmental and genetic factors affecting seed set in Dactylis glomerata L.

Creator:: West, David L.
Abstract:: Field, growth chamber, and greenhouse studies were carried out to evaluate factors that cause low seed set in Dactylis Glomerata L. The variety, 'Latar', and the parental clones of the variety, 'Pennlate', were studied in detail. Floral anatomy investigations indicated that 98 percent of Dactylis flowers opened at Corvallis in...

Transient heat and mass transfer in soils in the vicinity of heated porous pipes

Creator:: Slegel, David L.
Abstract:: Differential equations governing the combined heat and mass transfer in soils are developed. Transient heat, liquid and vapor transfer with phase change is considered. The liquid transfer is treated as a function of the hydraulic conductivity and the gradient of suction potential. The suction potential is considered a function of...

The solid state photochemistry and photophysics of a triphenylmethyl dye cyanide

Creator:: Vernier, David L.
Abstract:: Triphenylmethyl dye cyanides have been known to be sensitive to ultraviolet radiation since early in this century. Under appropriate conditions, exposure to uv leads to heteropolar fission of the C-CN bond (photoionization) and intense coloration due to dye formation. Thin homogeneous films of hexahydroxyethyl pararosaniline cyanide in a nylon matrix...

Effect of elevation, aspect, canopy, and season on soil temperature measurements for soil classification

Creator:: Green, David L.
Abstract:: The effects of aspect, canopy, elevation, and season both singly and in combination on soil temperatures at 50 cm depths were evaluated. The objectives of the study were (i) to develop a standard procedure for obtaining soil temperature data adequate to classify soils at the family and great group levels,...

Low frequency variations in the sea level and currents over the Oregon continental shelf

Creator:: Cutchin, David L.
Abstract:: Sea level and current observations made over the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cpd. In a narrow band around 0.22 cpd the current-sea level relationship is consistent with the predicted values for the first mode of Robinson's continental shelf waves....

Annual bluegrass (Poa annua L.) control with ethofumesate during turfgrass establishment

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...
