Understory vegetation response and nitrogen cycling following cutting of western juniper

Creator:: Bates, Jonathan D.
Abstract:: Since the late 1880's western juniper has expanded in range and increased in density in sagebrush-bunchgrass, riparian, and forested plant communities of the Pacific Northwest. Succession to western juniper woodland has been shown to reduce the productivity and diversity of the understory component, result in concentration of soil nutrients beneath...

Partial characterization of the P4 pathotype of pea seedborne mosaic virus

Creator:: Kohnen, Paul D.
Abstract:: Biological, serological, and molecular characteristics of the P4 pathotype of pea seedborne mosaic potyvirus (PSbMV) were investigated. The characterization allowed P4 to be differentiated from other pathotypes of the same virus. P4 was distinguished from P1 on the basis of host symptomatology. It induced varied, but often distinctive symptoms in...

Analytical framework for modeling scale-related variabilities in remote sensing

Creator:: Chen, Chaur-fong
Abstract:: A general analytical framework was established to investigate the scale-related variabilities in remote sensing. The variabilities were studied first by investigating canopy structure, canopy interaction with light, relation between spectral reflectance and plant phenological parameters. The variabilities simulated by the plant model were compared with the actual spectral data acquired...

Lowpass and bandpass current-mode delta-sigma DACs employing mismatch-shaping

Creator:: Shui, Tao, 1969-
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold....

Delta-sigma modulators employing continuous-time circuits and mismatch-shaped DACs

Creator:: Zhang, Bo
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters. These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold.

Multi-bit delta-sigma switched-capacitor DACs employing element-mismatch-shaping

Creator:: Lin, Haiqing
Abstract:: Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters (ADCs and DACs). Most delta-sigma modulators in production today employ single-bit quantization because a 1-bit DAC is inherently linear, whereas a multi-bit DAC is not. Were it not for this drawback, the use of multi-bit...

Employed mothers' satisfaction with child care choices : perceptions of accessibility, affordability, quality, and workplace flexibility

Creator:: Elliot, Janis Sabin
Abstract:: Interest in child care has grown dramatically, yet little is known about how families manage to ensure appropriate child care. In a secondary analysis of data from 642 employed mothers representing a wide range of income levels, this research identified the factors contributing most to mothers' satisfaction with child care...

Women's feelings about the work-family interface of long-haul truck drivers : six days on the road and he's gonna be home tonight

Creator:: Moon, Susan F.
Abstract:: Long-haul truck drivers are absent from their families for prolonged periods of time. This paper examines the methods trucking families use to remain connected given such absences. Interviews with ten women married to long-haul truck drivers underwent qualitative analysis. Initially, personal profiles were developed to illustrate life experiences of the...
