The Rincon Astrolabe Shipwreck
(Texas A&M University, 2006-04-12)
On 30 December 1986, a local fisherman incidentally discovered the remains of a
seventeenth-century merchantman off the coast of Rincon, a small municipality on
Puerto Rico's west coast. Some days later, he and some ...
Species composition and seasonal abundance of stink bugs in cotton in the Lower Texas Gulf Coast and the virulence of Euschistus species to cotton
(Texas A&M University, 2006-04-12)
Stink bugs are beginning to emerge as important pests of cotton that often require management in the Lower Texas Gulf Coast. As eradication of the boll weevil progresses and producers increasingly adopt transgenic cotton ...
Development of a 2-D black-oil reservoir simulator using a unique grid-block system
(Texas A&M University, 2006-04-12)
The grid orientation effect is a long-standing problem plaguing reservoir simulators that employ finite difference schemes. A rotation of the computational grids yields a substantially different solution under certain ...
Use of a thermodynamic cycle simulation to determine the difference between a propane-fuelled engine and an iso-octane-fuelled engine
(Texas A&M University, 2006-04-12)
A thermodynamic cycle simulation of the four-stroke spark-ignition engine was
used to determine the effects of variations in engine design and operating parameters on
engine performance and emission characteristics. The ...
Feature identification framework and applications (FIFA)
(Texas A&M University, 2006-04-12)
Large digital libraries typically contain large collections of heterogeneous resources
intended to be delivered to a variety of user communities. One key challenge for these
libraries is providing tight integration between ...
Predator induced defenses in prey with diverse predators
(Texas A&M University, 2006-04-12)
Phenotypic plasticity is an environmentally based change in phenotype and can be
adaptive. Often, the change in an organism's phenotype is induced by the presence of a
predator and serves as a defense against that predator. ...
Evaluation of fisheries by-catch and by-product meals in diets for red drum (Sciaenops ocellatus)
(Texas A&M University, 2006-04-12)
By-catch and wastes from processed fish and shrimp constitute a sizeable portion of commercial fishery landings. This discarded material is potentially valuable, for its content of fish meals and other substances. Fish ...
Preconditioned solenoidal basis method for incompressible fluid flows
(Texas A&M University, 2006-04-12)
This thesis presents a preconditioned solenoidal basis method to solve the algebraic
system arising from the linearization and discretization of primitive variable
formulations of Navier-Stokes equations for incompressible ...
Comparative study of authentic scientific research versus guided inquiry in affecting middle school students' abilities to know and do genetics
(Texas A&M University, 2006-08-16)
This exploratory mixed methods study addressed the types of gains students made
when engaged in one of two forms of inquiry. Gains were measured on three levels:
conceptual understanding, the process of scientific ...
Development of a control algorithm for a dynamic gas mixing system
(Texas A&M University, 2006-08-16)
An algorithm was developed to control the partial pressures of N2, O2, and CO2
in a gas mixing tank. The gases were premixed before being introduced into the low
pressure Mars Dome. As an attempt to reduce the effects of ...
