Dynamics of marine pelagic bacterial communities on the Texas-Louisiana shelf
(2009-05-15)
Microbial community interactions within many ecosystems are still relatively
unknown. Investigating links between environmental dynamics and shifting pelagic
bacterial community structures on the Texas-Louisiana shelf, ...
Spatio-temporal distribution of white-tailed deer (Odocoileus virginianus) relative to prescribed burns on rangeland in South Texas
(2009-05-15)
Overgrazing and fire suppression has left much rangeland in poor condition for
various wildlife species. Prescribed fire is one range improvement practice used to
restore degraded wildlife habitat. I determined the effect ...
Roles for extra-hypothalamic oscillators in the avian clock
(2009-05-15)
Avian circadian clocks are composed of a distributed network of neural and
peripheral oscillators. Three neural pacemakers, located in the pineal, the eyes, and the
hypothalamus, control circadian rhythms of many biological ...
Genomic and metagenomic approaches to natural product chemistry
(2009-05-15)
For many years, natural products have been a primary source of new molecules for the
treatment of disease, and microorganisms have been a prolific source of these molecules. Recent
studies have indicated, however, that ...
Mexican american teachers tell their stories of success in the midst of a colonia
(2009-05-15)
The purpose of the study was to investigate how teachers at an elementary
campus located in the midst of a Colonia perceived their achieved academic recognition
when more rigorous federal and state standards seem to challenge ...
To enter and lead: renegotiating meanings of leadership and examining leadership theory of social power from the perspectives of African American women leaders in predominantly white organizations
(2009-05-15)
This qualitative, phenomenological study examined the leadership experiences of 10 African American women (AAW)--current or former leaders in predominantly white organizations--to gain an understanding of how well, or not, ...
Analysis of the Arabidopsis NAC gene superfamily in plant development
(2009-05-15)
There are a vast number of transcription factors that regulate plant growth and development. The NAC gene superfamily is one of the largest families of transcription factors in the plant kingdom. NAC gene expression profiles ...
Direct torque control of permanent magnet synchronous motors with non-sinusoidal back-EMF
(2009-05-15)
This work presents the direct torque control (DTC) techniques, implemented in
four- and six-switch inverter, for brushless dc (BLDC) motors with non-sinusoidal back-
EMF using two and three-phase conduction modes. First ...
One dimensional electron spin imaging for single spin detection and manipulation using a gradient field
(2009-05-15)
The ability to resolve molecules individually has many potential applications.
These include understanding the local environments of single molecules including
details of their interactions with surroundings. The ability ...
Solution-mediated strategies for synthesizing metal oxides, borates and phosphides using nanocrystals as reactive precursors
(2009-05-15)
Because of their high surface area (and hence, increased reactivity) nanocrystals can be used as reactive precursors in the low-temperature synthesis of solid state materials. When nanocrystals are used as reactants, the ...
