Characterization and isolation of a rotifer-deterrent compound in the red tide dinoflagellate Karenia brevis
(Georgia Institute of Technology, 2006-12)
Spontaneous phytoplankton blooms cause extensive damage to aquatic ecosystems all over the world. Red Tide, a type of bloom, causes extensive damage in the Gulf of Mexico every year. Red tide is caused by Karenia brevis, ...
Cylindrical beam volume holograms recorded in reflection geometry for diffuse source spectroscopy
(Georgia Institute of Technology, 2008-05-06)
Multimodal multiplex spectroscopy (MMS) has been demonstrated to increase the optical throughput of a spectrometer as opposed to that of conventional optical spectrometers and has been implemented using three-dimensional ...
Hybridization versus Randomly-Sorting Ancestral Alleles: Genetic Variation in Lake Malawi Cichlids
(Georgia Institute of Technology, 2007-05)
Hybridization is believed to be an important mechanism for genetic diversity and speciation in many groups of organisms. One of the most important evolutionary signatures of hybridization is low phylogenetic resolution in ...
Nonverbal Feedback Integration: A Controlled System
(Georgia Institute of Technology, 2008-05-05)
Conversations involve the exchanging of feedback, both verbal and nonverbal, and the importance of these cues is well understood. The cognitive processes used in integrating the feedback have yet to examined, especially ...
Chemical Mate-tracking in Copepods: A Comparison of Hesperodiaptomus shoshone and Temora longicornis
(Georgia Institute of Technology, 2007-05)
Males of the marine copepod species Temora longicornis have been seen to track the chemical trails of females in order to locate the female for mating. The males of one freshwater copepod, Hesperodiaptomus shoshone, have ...
Driver Onset Braking Time: The Uncertainty Involved With Approaching an Intersection
(Georgia Institute of Technology, 2008-05-05)
Many automobile accidents occur at intersections, which are often controlled by stop signs and traffic lights. Understanding how a driver interprets, anticipates, and responds to stop signs and traffic lights could help ...
Lateral gene transfer of pandemic Vibrio parahaemolyticus genomic island genes
(Georgia Institute of Technology, 2008-12-15)
Vibrio parahaemolyticus is an emerging enteric pathogen. The O3:K6 serotype has become pandemic, and the genome has been sequenced for the RIMD2210633 strain of this serotype (20). The thermostabile direct hemolysin (tdh), ...
Chemical manipulation of dental patterning in Malawi cichlids
(Georgia Institute of Technology, 2008-05-05)
A dynamic model for odontogenesis is lacking. Cichlids serve as superior organisms for studies in tooth development because of diversity in tooth shape, size, number, number of rows, all of which undergo continuous ...

(Georgia Institute of Technology, 2008-05-06)
Historically, fan culture has played an enormous role in the creation and development of science fiction and fantasy, and the genres have left a significant impact on the lives of their fans. I have determined that fandom ...
Functional Neuroimaging Investigation of the Neural Mechanisms for Successful Feeling-of-Knowing Judgments
(Georgia Institute of Technology, 2009-05-04)
A feeling-of-knowing (FOK) is a sense of knowing that an item would be recognizable if seen again later, despite one’s current inability to recall that item from memory. An FOK judgment occurs after a memory search and is ...
