Novel instrumentation for a scattering independent measurement of the absorption coefficient of natural waters, and a new diffuse reflector for spectroscopic instrumentation and close cavity coupling
(Texas A&M University, 2007-04-25)
We report results for the development of a flow-through integrated cavity absorption meter (ICAM.) Absorption measurements have been made with 2% or less change in the signal in the presence of up to 10 m-1 of scattering ...
Relationships between observed pore and pore-throat geometries, measured porosity and permeability, and indirect measures of pore volume by nuclear magnetic resonance
(Texas A&M University, 2007-04-25)
Carbonate reservoirs are a network of pores and connecting pore-throats that
contain at least half of the world's oil. Genetic classification of carbonate pores enables
one to map the pore types that have greatest influence ...
Lichen: the challenge for rock art conservation
(Texas A&M University, 2007-04-25)
This study investigates the effects that lichens have on rock surfaces in which
ancient rock art (petroglyphs and pictographs) may be found. The study area includes
four sites in the United States: one quartzite site in ...
Transient finite element analysis of electric double layer using Nernst-Planck-Poisson equations with a modified stern layer
(Texas A&M University, 2007-04-25)
Finite element analysis of electric double layer capacitors using a transient
nonlinear Nernst-Planck-Poisson (NPP) model and Nernst-Planck-Poisson-modified
Stern layer (NPPMS) model are presented in 1D and 2D. The NPP ...
Bioremediation of the organophosphate pesticide, coumaphos, using microorganisms immobilized in calcium-alginate gel beads
(Texas A&M University, 2007-04-25)
Coumaphos is an organophosphate insecticide used predominantly by the US Department of Agriculture, Animal and Plant Health Inspection Services for its tick eradication program. Bioremediation of the hydrolysis products ...
Systematization of water allocation systems: an engineering approach
(Texas A&M University, 2007-04-25)
The allocation of water resources is typically accomplished within the framework of
water allocation systems (WAS). In general, a WAS sets priorities, applies rules, and
organizes responses to a range of water allocation ...
Wildlife and water: collective action and social capital of selected landowner associations in Texas
(Texas A&M University, 2007-04-25)
In Texas, landowner associations for the management of common-pool resources
such as wildlife and groundwater have become increasingly popular. Successful
management of white-tailed deer (Odocoileus virginianus) depends ...
Ecological patterns of the small mammal communities at El Cielo Biosphere Reserve, Tamaulipas, Mexico
(Texas A&M University, 2007-04-25)
Scarce knowledge of Neotropical small mammal communities prevents
experimental inquiry on the mechanisms structuring these communities. In this study, I
examined patterns of local assembly of the small mammal communities ...
Investigating insect molecular responses to two plant defense proteins and characterizing a novel insecticidal protein from Arabidopsis
(Texas A&M University, 2007-04-25)
The molecular interaction between plants and insects is dynamic and
multifaceted. We are interested in understanding the molecular mechanism that insects
utilize to overcome plant defense proteins, as well as discovering ...
An investigation of bulk nanocrystalline copper fabricated via severe plastic deformation and nanoparticle consolidation
(Texas A&M University, 2007-04-25)
Ultrafine grained (UFG) and nanocrystalline materials have attracted considerable
interest because of their unique mechanical properties as compared with coarse grained
conventional materials. The fabrication of relatively ...
