Gene expression patterns of encapsulated microbial cells
… Saccharomyces cerevisiae (S. cerevisiae) cells encapsulated within three distinct nanostructured silica matrices and relate those patterns to known naturally occurring metabolic states. It was found that the cells for all three-encapsulated methods enter quiescent states characteristic of …

Electromechanical Modeling of Encapsulated Ionic Polymer Transducers
A model to allow the design and evaluation of encapsulated ionic polymer transducers is developed. This model in based on a linearly coupled, two port, electrical equivalent circuit model (Newbury, 2002). The proposed model incorporates multilayer beam theory to model the passive stiffness effects …

Size Dependent Antimicrobial Properties of Sugar Encapsulated Gold Nanoparticles
<p>The antimicrobial properties of dextrose encapsulated gold nanoparticles (dGNPs) with average diameters of 25 nm, 60 nm, and 120 nm (± 5 nm) synthesized by green chemistry principles were investigated against both Gram-negative and Gram-positive bacteria. Studies were performed involving the …

Encapsulated source contact dose estimates incorporating secondary electron emission
Secondary electron emission generated at the surface of thin material from interaction with gamma rays form a significant component of the surface dose. The intensity of this emission is known to vary with material composition and incident radiation energies. The goal of this research effort is to …

Encapsulated Contrast Agent Markers For Mri-Based Post-Implant Dosimetry
… To aid with seed localization, MRI markers with encapsulated contrast agent that provide positive-contrast on MRI images (Sirius MRI markers; C4 Imaging, Houston, TX) have been proposed to be placed adjacent to the negative-contrast seeds. This dissertation describes the development of the Sirius …

Reconfigurable SCA System Development Using Encapsulated Waveform Applications and Components
The Software Communications Architecture (SCA) is a standard for software defined radios (SDR) designed in part to promote code reuse for long-term development. With the emergence of adaptive/cognitive radios, new SDRs that are capable of reconfiguration during runtime must be developed. One …
