Three trends are occurring today in the United States which inspired this research. First, America is growing increasingly urbanized. Today, more Americans are living in cities than in rural environments, and this pattern is predicted to continue for the foreseeable future. Urban living has benefits, but there are also challenges...
This thesis investigates Contextual Teaching and Learning (CTL) as a method of instruction for natural resources education. The research follows the adoption of CTL in the K-12 classrooms of six teachers focusing on natural resources education at two rural schools in Western Oregon. CTL is being investigated because it connects...
The change in the oscillation frequency in the current of
an atmospheric helium glow discharge is a sensitive detector
for gas chromatography. The response of the detector is in
the femtomole and picomole range for nonane and decane. The
effluent of a capillary column is directed into a glow
discharge...
Breakthroughs in heat sink design are now limited by conventional manufacturing techniques which can only produce basic fin shapes with homogenous surface structuring. Additive Manufacturing (AM) is a potential disruptive technology for heat sink design and other convective heat transfer solutions, as surface properties can be directionally varied to maximize...
Developmental research has suggested that parenting practices may impact the
development of risk behaviors later in life. However, little evidence exists regarding
how parenting may impact actual decision processes that precede poor choices. This
study examined how parenting practices in early childhood influence the development
of decision-making competence (DMC), a...
Boiling dynamics and related heat transfer mechanisms have been widely studied for several decades. During that time, incredible progress has been made on quantifying bubble departure phenomena including growth rate, departure frequency, associated natural and forced convection, and radiation additions to the overall heat transfer rate. With this, the thermal...
The Confucius Institutes program is a Chinese organization established in 2004 to provide the world with language instruction and increase cultural awareness. The program forms joint venture business models with universities and schools around the world to establish language and culture centers on their school’s campus (“Constitution and By-Laws”). Over...
The development of a continuous and reliable cooling method for computer chips is an evolving subject requiring continuous research in both computer science and thermal management. Two-color laser induced fluorescence (LIF) provides a non-invasive way to investigate electronics cooling fluid behavior. Dielectric fluids are of particular interest as they allow...
