Biogeographic Relationships of Pocket Gophers (Geomys breviceps and Geomys bursarius) in the Southeastern Portion of Their Ranges

Description: This research utilized population genetic analyses (protein starch-gel electrophoresis and DNA sequencing of the cytochrome b mtDNA gene), host-parasite specificity (lice coevolution), remote sensing of satellite data, and geographic information systems (GIS) to characterize newly discovered populations of pocket gophers (genus: Geomys) in Arkansas. These populations are isolated and occur in seemingly unsuitable habitat in the Ozark Mountains of Arkansas. Analyses of electrophoretic and ectopa… more

Circumfusion: a Composition for Real-Time Computer Music Spatialization System

Description: Two of the leading methodologies for spatializing audio over multiple channels include non-real-time multi-track tape and variations of real-time systems that often involve complex configurations of hardware. Of the latter, composers relying on MIDI as a control source have used pairs of sound modules, effects units and automation capable mixers to achieve spatialization over four loudspeakers. These systems typically employ intensity panning, Doppler shifts and reverberation. The present rese… more

Conceptual Structure of HIV+ Women With PTSD: Trauma Construct Elaboration

Description: Human immunodeficiency virus (HIV) can result in posttraumatic stress disorder (PTSD) as events related to illness act as traumatic stressors. This study tested some basic hypotheses of Sewell and Cromwell's personal construct model of PTSD in HIV+ women both with and without diagnoses of PTSD. Trauma-related constructs of HIV+ women with PTSD with HIV+ non-PTSD controls at varying stages of illness were compared. The elaboration, rankings, and valence of trauma-related constructs were examined… more

Development of an In Vitro Protoplast Culture System for Albizia Lebek (L.) Benth., an Economically Important Leguminous Tree

Description: An in vitro system of generating protoplasts from their callus cultures was established. The friable callus was more productive in terms of producing protoplasts than the green compact callus. The concentration of the various cell wall degrading enzymes had an effect on the viability of the protoplasts in the medium. The protoplast system developed from the experiments was stable and could be used for the transformation experiments of Albizia lebek and for other plant improvement practices.
