Solid solutions ceramics of the Bi(Zn0.5Ti0.5)O-3-(Bi0.5K0.5)TiO3-(Bi0.5Na0.5)TiO3 ternary system for <20 mol. % BZT were created and confirmed to be single phase using x-ray diffraction. The dielectric dispersion showed decreasing T-max of the dielectric spectrum with a broadening of the transition with increasing BZT content. At 2.5BZT-40BKT-57.5BNT, a secondary transition commonly...
Benchmark calculations are performed for neutron transport in a two material
(binary) stochastic multiplying medium. Spatial, angular, and energy dependence
are included. The problem considered is based on a fuel assembly of a common
pressurized water nuclear reactor. The mean chord length through the assembly is
determined and used as...
One of the pervasive problems arising in our modern, digital world surrounds data breaches where an adversary, through zero-day exploitations, phishing, or old-fashioned social engineering attacks, gains access to a service’s data stores. Our society increasingly relies on these cloud-based services for everything from our taxes to personal communication. As...
In his July 31, 1996 remarks on welfare reform, President Clinton signaled his intent to sign into law the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA), bipartisan legislation aimed at reforming federal welfare policy. During the press conference, Clinton framed welfare as necessary but ultimately temporary relief, stating its...
Since the International Commission on Radiation Protection (ICRP) recommended a revision to the eye lens dose limits in ICRP Publication 118 (Stewart, 2012) the radiation protection community has conducted many new studies related to eye dosimetry. The recommended reduction of eye lens dose limits may result in the reduction of...
This thesis develops a framework for analyzing the application of commuter rail and
bus services between several small urban centers to enhance overall connectivity. The
study includes analyzing specific performance criteria for commuter rail service and
express bus service based on data from existing systems around the U.S. The study...
Increasing international trade and tourism have led to an increase in the introduction of exotic pests that pose a considerable economic threat to the agro-ecosystems of importing countries. Scale insects (Sternorryncha: Coccoidea) may be contaminants of export consignments from the South African deciduous fruit industry to the European Union, Israel,...
We report here that (4R,9Z)-hexadec-9-en-4-olide [(R)-desmolactone] is a sex
attractant or sex pheromone for multiple species and subspecies in the cerambycid
genus Desmocerus. This compound was previously identified as a female-produced
sex attractant pheromone of Desmocerus californicus californicus.
Headspace volatiles from female Desmocerus aureipennis aureipennis contained
(R)-desmolactone, and the antennae...

We used metatranscriptomics to study the gene transcription patterns of microbial plankton (0.2 to 64 μm) at a mesohaline station
in the Chesapeake Bay under transitions from oxic to anoxic waters in spring and from anoxic to oxic waters in autumn.
Samples were collected from surface (i.e., above pycnocline) waters...
