Duty cycle of switched, constant current circuit controlled by pressure sensor provides oxygen at a constant pressure from a cell which electrolyzes water, eliminating possibility of cell damage by excessive oxygen demand
Amber J. Powell - Blaming the Victim: A Look at Sexual Assault Adjudication in the Milwaukee County Courthouse
Even though several studies explore common themes in victim-blaming strategies amongst adult sexual assault cases, very few address how these techniques are used to blame and discredit child sexual assault victims. Therefore, this study compared the cultural narratives used by defense attorneys to blame adult and child sexual assault victims in the courtroom. The study sample consisted of 18 sexual assault cases (5 adult victims and 13 child victims) in three branches of the Milwaukee county courthouse in Milwaukee Wisconsin. The defendants and victims in these cases represent a various ethnicities, ages, and social economic backgrounds. Employing a mixed-methods approach, this study used ethnographic observational data, archival research, and secondary data analysis to compare victim-blaming strategies during jury trials and sentencing hearings. Observational data was collected between May and June 2013, while secondary data was collected between September 2011 and May 2012. Archival data was provided by Consolidated Court Automation Programs (CCAP) and shows records of cases in the Wisconsin Circuit Courts. Jury trials and sentencing hearings play an important role in comprehending victim blaming because defense attorneys often use those times as an opportunity to discredit the victim. Results show that the narratives utilized work to hold adult and child victims as unbelievable across a variety of themes relating to consent, reliability, and corroboration. A narrative of rebelliousness was also invoked particularly as it pertained to child victims. The importance of these findings is elaborate in the discussion.https://epublications.marquette.edu/mcnair_2013/1015/thumbnail.jp

Conservation laws, radiative decay rates, and excited state localization in organometallic complexes with strong spin-orbit coupling
There is longstanding fundamental interest in 6-fold coordinated
() transition metal complexes such as [Ru(bpy)] and
Ir(ppy), particularly their phosphorescence. This interest has increased
with the growing realisation that many of these complexes have potential uses
in applications including photovoltaics, imaging, sensing, and light-emitting
diodes. In order to design new complexes with properties tailored for specific
applications a detailed understanding of the low-energy excited states,
particularly the lowest energy triplet state, , is required. Here we
describe a model of pseudo-octahedral complexes based on a pseudo-angular
momentum representation and show that the predictions of this model are in
excellent agreement with experiment - even when the deviations from octahedral
symmetry are large. This model gives a natural explanation of zero-field
splitting of and of the relative radiative rates of the three sublevels
in terms of the conservation of time-reversal parity and total angular momentum
modulo two. We show that the broad parameter regime consistent with the
experimental data implies significant localization of the excited state.Comment: 8 pages, 6 figs + sup info (20 pages, 19 figures - to view pdf

The origin of the difference in the superconducting critical temperatures of the beta_H and beta_L phases of (BEDT-TTF)_2I_3
Incommensurate lattice fluctuations are present in the beta_L phase (T_c =
1.5 K) of ET_2I_3 (where ET is BEDT-TTF -
bis(ethylenedithio)tetrathiafulvalene) but are absent in the beta_H phase (T_c
= 7 K). We propose that the disorder in the conformational degrees of freedom
of the terminal ethylene groups of the ET molecules, which is required to
stabilise the lattice fluctuations, increases the quasiparticle scattering rate
and that this leads to the observed difference in the superconducting critical
temperatures, T_c, of the two phases. We calculate the dependence of T_c on the
interlayer residual resistivity. Our theory has no free parameters. Our
predictions are shown to be consistent with experiment. We describe experiments
to conclusively test our hypothesis.Comment: 4 pages, 1 figur
Tone-burst technique measures high-intensity sound absorption
Tone-burst technique, in which narrow-bandwidth, short-duration sonic pulse is propagated down a standing-wave tube, measures sound absorbing capacity of materials used in jet engine noise abatement. Technique eliminates effects of tube losses and yields normal-incidence absorption coefficient of specimen
