Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Genetic variability for kernel hardness in two soft winter wheat (Triticum aestivum L.) cultivators

Creator:: Albahouh, Muhammed S.
Abstract:: To remain competitive in the international marketplace, soft white wheat cultivars grown in the Pacific Northwest must have consistent and predictable flour properties including kernel texture. As a consequence, there is a need to develop wheat cultivars for specific end uses. Wheat cultivars with very soft kernels are used largely...

Development of a mechanistic overlay design procedure for flexible pavements

Creator:: Zhou, Haiping
Abstract:: This dissertation describes the development of a mechanistic overlay design procedure. The mechanistic analysis represents a new trend in both new pavement and overlay design. The greatest advantage of the mechanistic pavement analysis is that it considers the fundamental characteristics of materials to be used, is capable of considering changes...

Assessment of impacts of Canada geese on wheat production

Creator:: Louhaichi, Mounir
Abstract:: Numbers of wild Canada geese (Branta canadensis) have increased dramatically during the past 30 years in the lower Columbia and Willamette Valley systems. The damage they cause by grazing and trampling plants can be substantial. The objectives of this research were to: 1) Develop methods that provide reliable estimates of...

Determination of structural layer properties of aggregate and asphalt surfaced roads

Creator:: Rwebangira, T.
Abstract:: This study involved the determination of the structural layer properties of aggregate and asphalt surfaced pavements for use in the evaluation of pavement load carrying capacity and the seasonal effects of moisture. This was achieved by the use of Nondestructive Testing Methods (NDT) and backcalculation techniques. Pavement surface deflection measurements...

Comparison of underemployed and not underemployed women in two-parent two-child families : an eleven-state rural-urban study

Creator:: Masuo, Diane M., 1947-
Abstract:: This study compared wives defined as underemployed by educational mismatch with not underemployed wives on four major predictor variables-- relative market work advantage; degree of competition in the female labor market; time demands from family members; and assistance with childcare and other housework. The data were from NE 113, An...

Factors affecting bird counts and their influence on density estimates

Creator:: McCracken, Marti L.
Abstract:: Variable area surveys are used in large geographic regions to estimate the density of birds distributed over a region. If some birds go undetected, a measure of the effective area surveyed, the amount of area occupied by the birds detected, is needed. The effective area surveyed is determined by observational,...

Food preferences of Thai adolescents and their mothers' attitudes and knowledge about foods and nutrition

Creator:: Sananmuang, Ratana
Abstract:: The purpose of this study was to investigate the relationships between adolescents' food preferences and their mothers' attitudes and knowledge about foods and nutrition in Phitsanulok Province, Thailand. Subjects included 30 boys and 35 girls randomly selected from 11th grade classrooms at two high schools in Phitsanulok, and their mothers....

Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

Creator:: Nichols, William E.
Abstract:: The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...
