Evaluation of tick-host-landscape interactions using spatial analysis
(Texas A&M University, 1997)
Cattle-landscape interactions were evaluated by monitoring movement of cattle on a rangeland landscape using a differential global positioning system (DGPS). Cattle were inspected for ticks before and after each 48 hour ...
Response of in situ leaf psychrometer to cuticle removal by abrasion
(Texas A&M University, 1997)
In situ measurements of leaf water potential are important for monitoring the energy state of water in plants. Thermocouple psychrometry is an acceptable measurement method, where leaf water status is inferred by analysis ...
An investigation into the use of highway traffic signals at highway-railroad grade crossings
(Texas A&M University, 1997)
Rail-highway grade crossings are amongst the most dangerous of intersections a driver will encounter. One out of every nine accidents at rail-highway crossings produces a fatality. In half of these cases, the crossing is ...
Minimum cost air pollution control for cotton gins
(Texas A&M University, 1997)
With the implementation of the 1990 Federal Clean Air Act Amendments (CAAA), State Air Pollution Regulatory Agencies (SAPRA's) are regulating agricultural operations across the U.S. more vigorously. Some of these agricultural ...
A model for predicting the damage and oxidation dependent life of SCS-6/Ti-B21S [0]4 metal matrix composite
(Texas A&M University, 1997)
A method for predicting the life of an embrittled metal matrix composite using the finite element method coupled with models for material inelasticity, surface embrittlement, and crack propagation was developed herein. The ...
A quantitative evaluation methodology for the sourcing of public sector job functions
(Texas A&M University, 1997)
Public agencies contract out job functions with the objective of utilizing their resources more efficiently. Some major reasons for an organization to contract out services with private sector firms have been, ³to supplement ...
Rotordynamic evaluation of a roughened-land hybrid bearing
(Texas A&M University, 1997)
Hybrid bearings (combinations of hydrostatic and hydrodynamic bearings) represent an attractive alternative to ball bearings for use in high-speed cryogenic turbopumps. However, the internally-developed cross-coupled forces ...
Identification of asphalt binder properties that affect cracking performance of hot mixed asphalt concrete pavements
(Texas A&M University, 1997)
The overall objective of this study was to identify binder properties that affect cracking performance of hot mixed asphalt concrete (HMAC) pavements. In the late 1980s, test pavements were constructed in Texarkana and ...
Food webs of two Venezuelan clear-water streams with seasonal fluctuations in hydrology
(Texas A&M University, 1997)
Two Venezuelan clear-water streams were sampled to describe resource use by fishes, community interactions, and the effects of seasonal environmental change and resource availability on food web structure. Previous studies ...
Stability of catalase and its role in lipid oxidation in beef muscle
(Texas A&M University, 1997)
When ground beef muscle (semimembranosus, SM) was aerobically refrigerated for 6 days with or without the addition of exogenous purified catalase (from bovine liver), there was no decline in catalase activity during storage. ...
