Stem form development of trees in response to wind has been established in the literature to be a response to stem sway induced by the wind. The response is manifested in modifications to height and diameter growth which strengthen the stem against wind stresses. Experiments in the literature show that...
The area studied in detail, known as the Antone District,
is located in the southeast corner of Wheeler County, Oregon, ,
between longitude 119 37. and 119°54 east, and latitude 44°23
and 44°3O' north.
Surface elevations range from 3050 feet above sea level in
the northeast corner of the district,...
WRRI 106 is placeholder for the research findings of Project No. G-928-03 funded by U.S. Dept. of the Interior, Geological Survey. Findings are available in Piehl, Bradley T. (1986) An evaluation of culverts on low volume forest roads in the Oregon Coast Range (Masters Thesis, Oregon State University. Forest Engineering)...
From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...
An important factor affecting the strength and ultimate load of wood structures is the strength, stiffness and durability of its joints. Therefore, the behavior of nailed joints must be given proper consideration when designing and analyzing wood structures. Presently,formulas for determining the strength of nailed joints under withdrawal loads, as...
Regression equations applicable to biomass components of standsof western hemlock [Tsuga heterophylla (Raf.) Sarg.} were developedby destructive sampling of a thinned and an unthinned stand ofwestern hemlock near Seaside, Oregon. Equations predicted more live-branchbiomass and less dead-branch biomass per tree for the thinnedstand, but equations for biomass of foliage, twigs,...
Surface and subsurface data are combined to determine the structure of the western half of the Simi fault system in the Las Posas and Camarillo Hills area. Cretaceous to Eocene sedimentary rocks, present only in the subsurface, are overlain by late Eocene to early Miocene nonmarine stata (Sespe Formation) and...
The Middle and West Forks of Little Sheep Creek in the southern Tendoy Range have incised valleys across Cenozoic structural features exposing strata that range in age from the Mississippian to the Neoene. Paleozoic strata are 1,349 m thick and belong to the Mission Canyon Limestone, the Big Snowy, Amsden,...
The Pennsylvanian rocks in south-central Idaho and adjacent areas consist of three main facies: a platform facies, a shelf facies, and a marginal basin facies. The platform facies is represented by the Amsden, Quadrant, and Tensleep Formations, in southwestern Montana and western Wyoming, and contain Middle and probably Lower Pennsylvanian...
The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...
The purpose of this study was to determine the nature and amountof genetic variation and possible associations between winterhardinessand earliness in winter x spring wheat crosses.Four winter wheat cultivars selected for differences in earlinessand winterhardiness were crossed with a nonhardy, day length insensitivespring wheat cultivar. The following year, experiments containing...
Subsurface mapping was used to determine the structure andgeologic history of the South Cuyama dome and part of the Russellfault in the South Cuyama oil field area. Deformed Late Cretaceousand or early Tertiary marine strata are unconformably overlain bythe late Oligocene to early Miocene Vaqueros Formation (QuailCanyon Sandstone Member, Soda...
The Santa Barbara-Montecito and Goleta basins are structurally
continuous fault-controlled Pleistocene basins containing
up to 3000 feet (925 m) of marine Pleistocene Santa Barbara Formation
which were deposited on previously deformed Sisquoc and older
strata. Structures subcropping against the unconformity at the
base of the Santa Barbara Formation show that...
The Grants Pass Batholith of Cretaceous age has intruded the
Triassic Applegate Group and metasedimentary rocks of the Jurassic
Galice Formation in the Murphy area of Josephine County, southwest
Oregon. The Applegate Group, mafic volcanic and sedimentary rock,
has been partially (nonequilibrium) metamorphosed under greenschist
facies conditions. The batholith, a...
Initial sites of localization and multiplication of Pasteurellamultocida were examined in chickens intravenously inoculated with varying doses of bacteria. Sections of lung, liver, kidney, bone marrow and spleen were prepared for light microscopic examination.Tissue sections were stained with the hematoxylin and eosin stain,Gram's stain or the avidin-biotin-peroxidase complex immunoenzymatictechnique. Of...
The purpose of this study was to examine the relativeeffectiveness of functional isometric squats on thedevelopment of dynamic strength, static strength and powerof college males. Ten college males volunteered for thestudy. The subjects trained two days per week for a totalof eight weeks which consisted of a two week preconditioningperiod...
The Ataspaca prospect is in the Cordillera Occidental, 45 km northwest of Tacna, Peru. Epizonal intrusions satellitic to the Caplina- Ataspaca pluton were emplaced 41 m.y. ago into limestones of the Lower Jurassic Pelado Formation along the northeast-trending Chucchuco fault system. Depths of emplacement ranged from 4.5 to 6.0 km....
