Multivortex micromixing: novel techniques using Dean flows for passive microfluidic mixing
(Texas A&M University, 2007-04-25)
Mixing of fluids at the microscale poses a variety of challenges, many of which
arise from the fact that molecular diffusion is the dominant transport mechanism in the
laminar flow regime. The unfavorable combination of ...
Children's achievement goals, attitudes, and disruptive behaviors in an after-school physical activity program
(Texas A&M University, 2007-09-17)
To promote active and healthy lifestyles in schoolage
children, many afterschool
physical activity programs offer students opportunities to participate in a variety
of physical activities. The effects of such programs on ...
Metal dependent structure, dynamics, and function in RNA measured by site-directed spin labeling and EPR spectroscopy
(Texas A&M University, 2007-04-25)
The structure and function of RNA molecules are dependent on RNA-metal ion interactions in both diffusive and direct ways. Structural information for RNA has been obtained using various biophysical and biochemical methods. ...
Factors determining the pKa values of the ionizable groups in proteins: their intrinsic pKas and the effects of hydrogen bonding on buried carboxyl groups
(Texas A&M University, 2007-04-25)
A goal of the modern protein chemist is the design of novel proteins with specific
activities or functions. One hurdle to overcome is the ability to accurately predict the
pKas of ionizable groups upon their burial in the ...
Shrink fit effects on rotordynamic stability: experimental and theoretical study
(Texas A&M University, 2007-09-17)
This dissertation presents an experimental and theoretical study of subsynchronous
rotordynamic instability in rotors caused by interference and shrink fit
interfaces. The experimental studies show the presence of strong ...
On simple and accurate finite element models for nonlinear bending analysis of beams and plates
(Texas A&M University, 2007-09-17)
This study is concerned with the development of simple and accurate alternative finite element models to displacement finite element models for geometrically
nonlinear bending analysis of beams and plates. First, a unified ...
Film cooling effectiveness measurements on rotating and non-rotating turbine components
(Texas A&M University, 2007-04-25)
Detailed film cooling effectiveness distributions were measured on the stationary
blade tip and on the leading edge region of a rotating blade using a Pressure Sensitive
Paint technique. Air and nitrogen gas were used as ...
Enhancing the resolution of sea ice in long-term global ocean general circulation model (gcm) integrations
(Texas A&M University, 2007-09-17)
Open water in sea ice, such as leads and polynyas, plays a crucial
role in determining the formation of deep- and bottom-water, as well
as their long-term global properties and circulation. Ocean general
circulation models ...
A rigorous compressible streamline formulation for black oil and compositional simulation
(Texas A&M University, 2007-04-25)
In this study for the first time we generalize streamline models to compressible flow using a
rigorous formulation while retaining most of its computational advantages. Our new formulation
is based on three major elements ...
Measurement of flammability in a closed cylindrical vessel with thermal criteria
(Texas A&M University, 2007-04-25)
Accurate flammability limit information is necessary for safe handling of gas and
liquid mixtures, and safe operation of processes using such mixtures. The flammability
limit is the maximum or minimum fuel concentration ...
