Many engineering devices and propulsion systems suffer from undesirable effects of cavitation; such as degradation in the efficiency of pumps and turbines, generation of noise and vibration on ship propeller, increased drag and erosion of propeller blade, etc.
In spite of decades of research on this problem, detailed study of...
The parallel implementation of a large number of functional units is necessary for
any industrial scale microfluidic process. The concept of a 'numbering up'
strategy where a single highly optimized functional unit that has a low individual
production is replicated a large number of times to create a device that...
Measurements of social constructs that evaluate natural hazard preparedness are important to decrease natural hazard vulnerability. Preparedness reduces natural hazard impacts and human vulnerability. Investment in education and education research contribute to human sustainable development and natural hazard preparedness. Faced with other needs, people typically do not prepare enough to...
This study examines the U.S. educational experiences of Saudi Arabian students. Using qualitative case study and photo-elicitation research methods, this study conducted multiple interviews with 25 Saudi students and explored their perceptions of their American learning environment, how it differed from Saudi Arabia, and the strategies they developed to successfully...
The internship I performed was with Rural Community Development Program (RCDP), a domestic non-governmental organization in the country of Nepal. This organization focuses on community development goals in rural communities, utilizing the efforts of volunteers within the context of environmental conservation ideals. I primarily worked with the associated community plant...
The Gene Ontology (GO) Consortium (http://www.geneontology.org) (GOC) continues to develop,
maintain and use a set of structured, controlled
vocabularies for the annotation of genes, gene
products and sequences. The GO ontologies
are expanding both in content and in structure.
Several new relationship types have been introduced
and used, along with...
The rural two-lane highway in the southeastern United States is frequently associated with a disproportionate number of serious and fatal crashes. The major research objectives are to investigate the relations between probabilities of fatal crash type occurrence and potential contributing factors from road geometric design characteristics and roadside, environmental features....
This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...
In this thesis, I conduct an analysis of paradigmatic background assumptions deployed in engineering decision-making processes, in order to understand how these assumptions, operating tacitly and in tension with each other, contribute to decisions that are ethically less effective and less substantial than they would otherwise be. I do so...
There is increasing evidence that aging is affected by biological (circadian) clocks – the internal mechanisms that coordinate daily changes in gene expression, physiological functions and behavior with external day/night cycles. Recent data suggest that disruption of the mammalian circadian clock results in accelerated aging and increased age‐related pathologies such...
