Solubilization of petroleum hydrocarbons using biosurfactants
(Texas A&M University, 1995)
Low solubility of petroleum hydrocarbons in water is the major factor limiting the degradation rates of these compounds (Zhang and Miller, 1994). The fraction that is more soluble in the aqueous phase is degraded at higher ...
An assessment of the potential environmental impact of electric and hybrid-electric vehicles in Texas
(Texas A&M University, 1998)
Increases in environmental and air quality problems due to continued growth in automobile population and usage have prompted many states including Texas to consider the implementation of an alternative vehicle program to ...
Comparison of day and night vehicular speeds on horizontal curves on rural two-lane highways
(Texas A&M University, 1996)
This thesis documents the research comparing day and night vehicular speeds on horizontal curves on rural, two-lane highways. For each selected curve, daytime and nighttime operating speeds were measured using piezoelectric ...
An evaluation of supplemental signing at two-way stop-controlled intersections
(Texas A&M University, 1996)
Drivers entering a two-way stop-controlled (TWSC) intersection with similar approach geometries and volumes may make the incorrect assumption that all approach legs are required to stop at the intersection. To respond to ...
Accelerated solvent extraction of petroleum contaminated sediments
(Texas A&M University, 1997)
Attempts have been made in recent years to find acceptable alternatives to classical soxhlet extraction of petroleum contaminated sediments. One such method that is very promising is accelerated solvent extraction also ...
Evaluation methodology for structures subjected to seismic loading
(Texas A&M University, 1996)
A method to evaluate the performance of new and existing structures subjected to earthquakes is proposed. This method, derived from the Capacity Spectrum Method, can be used by practicing engineers in the design of new ...
Dealing with uncertainty in estimating average annual flood damage for ungaged watersheds
(Texas A&M University, 1996)
Average annual damage (AAD) is a key central component of the hydrologic, hydraulic, and economic information developed in the evaluation of flood damage reduction plans. AAD or the expected value of annual damage, in ...
Evaluation of the adequacy of the 2000P test vehicle as a surrogate for light truck subclasses
(Texas A&M University, 1996)
This study evaluated the adequacy of the 2000P test vehicle as a surrogate for light truck subclasses. The National Cooperative Highway Research Program (NCHRP) Report 350 recommended the use of a 3/4-ton (approximately ...
A study of English and Spanish signing for Texas border towns
(Texas A&M University, 1998)
The purpose of this research was to identify English-phics. legend signs which have a low comprehension level among native Spanish-speaking drivers in Texas border areas and to develop and evaluate alternative Spanish and ...
