Until recently, occurrence of milk fever (MF) has been attributed to prepartum calcium intake. However, researchers in Iowa have concluded that high prepartum dietary potassium (K) is the major cause of MF. Potassium concentrations have been increasing on manure fertilized soils over the last 20 years. Grasses grown on these...
The effect of frozen storage time on the composition
of the cell wall polysaccharide (CWP) of muskmelon (Cucumis
melo) cultivars at different stages of maturity was investigated.
Changes in composition, firmness, drip loss, and
color of Cantaloupe and Honey Dew melon flesh were determined
at three stages of maturity and...
The goal of these experiments was to ensile combinations of shrimp or crab waste
with perennial ryegrass straw and analyze it for silage quality and ruminal degradability.
The rapid deterioration of seafood wastes required initial preservation prior to ensiling
to minimize odor production and protein breakdown. Eight experiments were conducted...
This ethnography describes RV [recreational vehicle] seasonal migration as an adaptive, transhumant strategy. The study population is retired, transhumant migrants, who are members of a nation-wide, membership camping organization. Fieldwork was conducted over a period of seven months at two sites located on the West Coast. These sites reflect northern...
Bacterial cultures enriched from sheep rumen fluid have demonstrated the ability to detoxify pyrrolizidine alkaloids (seneciphylline and jacobine) in tansy ragwort (Senecio jacobaea). The microbes are difficult to isolate using classical anaerobic techniques, therefore, microbes from two different enrichment cultures demonstrating similar degradation activity were identified using their 16S ribosomal...
Women leaders in early childhood health, human services, and education face tremendous challenges in their efforts to cultivate resilience amidst a myriad of risk factors including incessant stress, low wages, and limited professional support. Women who foster mental health in young children and high-risk families are vulnerable to secondary traumatic...
This thesis presents an examination of the nearshore wave bottom boundary layer
under conditions of significant sediment response. Using both field observations and
simple models, the response of the bottom boundary layer to random waves is shown to
have a complex behavior. First, the linearized wave bottom boundary layer governing...
The purpose of this qualitative study was to describe and communicate a student-constructed model of student services for electronic distance education (EDE). This study seeks to answer the following questions: Do students enrolled in EDE perceive a need for student services? If not, why not? Which services do students want/need?...
