Surface and subsurface geology of the Camarillo and Las Posas Hills area, Ventura County, California

Creator:: Jakes, Mary Clare
Abstract:: 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...

A geographical systems analysis of the commercial crawfish industry in south Louisiana

Creator:: Gary, Don L
Abstract:: The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...

Association and inheritance of earliness and winterhardiness in four winter x spring wheat crosses (Triticum aestivum Vill., Host)

Creator:: Yakar, Kamil
Abstract:: 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...

Distribution, form, and signigicance of plant opal in Oregon soils

Creator:: Norgren, Joel A.
Abstract:: This study was undertaken to increase knowledge of opal phytoliths in plants and soils of Oregon, and thus encourage further use of phytoliths in future pedologic investigations. Content of plant opal in needles from ten common Oregon conifer species ranged from 0.2 to 7.9%. Western larch (Larix occidentalis) contained the...

Identification of potential copper and molybdenum livestock nutrition problems with forage analysis

Creator:: Kresge, Paul Owen
Abstract:: Copper deficiency and Mo-induced Cu deficiency are nutrition problems of ruminant livestock in the Burns and Klamath Falls area of Oregon. Chemical analysis of plant and soil samples was used to survey Cu and Mo levels in forage in these areas. The objectives were to assess the possibility of animal...

Molybdenum status of subclover (Trifolium subterraneum) as affected by Mo and S fertilization and soil type

Creator:: Jarrell, Wesley M.
Abstract:: Field studies designed to study residual effects from fertilizer molybdenum were initiated in September 1971 on established grass-clover pastures at ten sites in Western Oregon. Treatments were 0.0 and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...

Subterranean clover yield and nutrient content as influenced by soil molybdenum status

Creator:: Bhella, Harbans Singh
Abstract:: During the Spring of 1969, 47 surface soil samples (0 to 15 cm) as well as foliage samples of subterranean clover were collected from 32 selected western Oregon pastures, in an effort to determine their molybdenum status and to evaluate the use of anion exchange resin method as a means...

A review of the family Eviphididae (Acarina: Mesostigmata)

Creator:: Shoemake, Rodger Russell
Abstract:: A complete taxonomic review of the Family Eviphididae was made for the first time. The family was found to contain forty-nine species and five genera. The genera included were: Eviphis Berlese, Scarabaspis Womersley, Alliphis Halbert, Pelethiphis Berlese, and Thinoseius Halbert. The new species described were: Eviphis oregonensis from Deschutes County,...

Economic analysis for a toll facility

Creator:: Koh, Kwang Sun
Abstract:: This thesis presents an economic analysis for a proposed toll road which is to separate different types of traffic such as pedestrians, slow speed vehicles and high speed motor vehicles, and to divert through traffic from the local roads. The use of a toll road usually provides significant savings in...
