Aerosol Condensational Growth in Cloud Formation
(2010-10-12)
A code for the quasi-stationary solution of the coupled heat and mass transport
equations for aerosols in a finite volume was developed. Both mass and heat are
conserved effectively in the volume, which results in a ...
Marble Transport in the Time of the Severans: A New Analysis of the Punta Scifo a Shipwreck at Croton, Italy
(2009-05-15)
Five ancient shipwrecks have been found in the sea off Croton, in southern Italy,
each carrying a marble cargo composed of massive blocks, column shafts, and smaller
artifacts. Three of them were located while surveying ...
Balancing human and system visualization during document triage
(2009-05-15)
People must frequently sort through and identify relevant materials from a large
set of documents. Document triage is a specific form of information collecting where
people quickly evaluate a large set of documents from ...
Evaluation of oocyte competency in bovine and canine species via non-invasive assessment of oocyte quality
(2009-05-15)
Traditional methods of oocyte selection for in vitro studies have proven inefficient with respect to achieving a level of predictability for competency. In this study, a novel method of oocyte selection was implemented ...
Surface spectroscopic studies of mono- and bimetallic model catalysts
(Texas A&M University, 2007-04-25)
This dissertation is focused on understanding heterogeneous bimetallic
catalysts using model catalyst systems, such as Pd-Au/Mo(110), Pd/Au(111) and
Pd/Au(100). Monometallic and bimetallic model catalysts, composed of Pd ...
Two linear slot nozzle virtual impactors for concentration of bioaerosols
(Texas A&M University, 2005-02-17)
Two experimental configurations of linear slot nozzle virtual impactors were
constructed and experimentally investigated for use as bioaerosol concentrators. In one
configuration, the Linear Slot Virtual Impactor (LSVI), ...
Damage assessment and sampling of the rice stink bug, Oebalus pugnax (Fabricius) (Hemiptera: Pentatomidae), in rice, Oryza sativa L., in Texas
(2009-06-02)
Field and greenhouse experiments were conducted from 2003 to 2006 at the Texas A&M University Agricultural Research and Extension Center at Beaumont and commercial rice fields throughout the Texas Rice Belt with the ...
A new structural subclass of constrained geometry catalysts for the polymerization of olefins
(Texas A&M University, 2006-04-12)
The sterically expanded octamethyloctahydrodibenzofluorene moiety, C29H38
(Oct), has been incorporated into ansa-metallocenes and constrained geometry catalysts
(CGC's). Utilization of this sterically expanded version of ...
Electronic structure of dimetal bonded systems: ditungsten, dimolybdenum and diruthenium systems
(Texas A&M University, 2007-04-25)
This dissertation investigates three topics in the field of multiple-bonded metal chemistry.
The first topic concerns the synthetic and theoretical considerations of ditungsten
formamidinates and guanidinates compounds. ...
Development of tandem time-of-flight instrumentation for the examination of prompt photodissociation of peptides using 193-nm radiation
(Texas A&M University, 2006-04-12)
The design and incorporation of a decelerating/accelerating cell into a reflectron
time-of-flight mass spectrometer is described for the examination of promptly-formed
photodissociation products of peptide ions. The ...
