Gustav Mahler's use and cyclic integration of motivic and thematic quotations (open access)

Gustav Mahler's use and cyclic integration of motivic and thematic quotations

All of Mahler's works may be divided into four distinct chronological groups, referred to as "symphonic cycles." Motives and themes from the songs within each symphonic cycle were quoted in symphonies in the same cycle. This system of self reference was unique to Mahler, although earlier composers such as Schubert and Wagner set precedents for some of the techniques used by Mahler. The quotations in the early periods appeared only on the surface and did not blend well with their surroundings, but as time progressed Mahler developed the ability to combine the seemingly incompatible elements more smoothly. Mahler's early fascination with distant sounds was also a factor in his use of quotations. The appendix contains a catalog of 100 quotations.

Picosecond degenerate four-wave mixing in semiconductors (open access)

Picosecond degenerate four-wave mixing in semiconductors

This study reports on a variety of experimental and theoretical studies conducted in ZnSe, CdTe, and in semiconductor-doped glasses. The transient picosecond degenerate four-wave mixing (DFWM) experiments performed in these II-VI direct-gap semiconductors are part of our efforts to understand the picosecond dynamics of the free-carriers generated via two and three-photon absorption.

A Comparison of Universal Soil Loss Equation Results Using a Remote Sensing/GIS Technique to Results Obtained Using a Field Survey Technique (open access)

A Comparison of Universal Soil Loss Equation Results Using a Remote Sensing/GIS Technique to Results Obtained Using a Field Survey Technique

Digital satellite remote sensing and Geographic Information Systems (GIS) have been used in conjunction with the Universal Soil Loss Equation (USLE) to model soil erosion potential within watersheds. This study compared erosion estimates calculated by the remote sensing method to results obtained in the field by soil conservationists using conventional methods.

Characterization of the Specificity of DNA Uptake and Transformation by Naturally Competent Acinetobacter Calcoaceticus (open access)

Characterization of the Specificity of DNA Uptake and Transformation by Naturally Competent Acinetobacter Calcoaceticus

Although cultures of A. calcoaceticus BD413 are naturally competent at all growth phases, genetic markers can only be successfully transformed by DNA from the genus Acinetobacter. Transformation frequencies of nearly 1.2% were obtained with pcaA mutants were incubated in liquid culture with wild-type DNA.

Modelling Land Use Change and Nonpoint Source Pollution Potential Using Remote Sensing and Geographic Information System Technology (open access)

Modelling Land Use Change and Nonpoint Source Pollution Potential Using Remote Sensing and Geographic Information System Technology

In this study Geographic Information System (GIS) technology was integrated with remote sensing techniques in order to determine the potential for nonpoint source pollution in the Lake Palestine and Cedar Creek Reservoir watersheds of North Central Texas. The Universal Soil Loss Equation was used to determine soil erosion potential from the watersheds, and export coefficients were used to estimate nutrient loadings into the reservoirs.
