Dark Sectors 2016 Workshop: Community Report

This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the status of this broad international field, the important milestones motivating future exploration, and promising experimental opportunities to reach these milestones over the next 5-10 years

The Effect of Hydrostatic Weighting on the Vertical Temperature Structure of the Solar Corona

We investigate the effect of hydrostatic scale heights ${\lambda}(T)$ in coronal loops on the determination of the vertical temperature structure $T(h)$ of the solar corona. Every method that determines an average temperature at a particular line-of-sight from optically thin emission (e.g. in EUV or soft X-ray wavelengths) of a mutli-temperature plasma, is subject to the emission measure-weighted contributions $dEM(T)/dT$ from different temperatures. Because most of the coronal structures (along open or closed field lines) are close to hydrostatic equilibrium, the hydrostatic temperature scale height introduces a height-dependent weighting function that causes a systematic bias in the determination of the temperature structure $T(h)$ as function of altitude $h$. The net effect is that the averaged temperature seems to increase with altitude, $dT(h)/dh > 0$, even if every coronal loop (of a multi-temperature ensemble) is isothermal in itself. We simulate this effect with differential emission measure distributions observed by {\sl SERTS} for an instrument with a broadband temperature filter such as {\sl Yohkoh/SXT} and find that the apparent temperature increase due to hydrostatic weighting is of order \Delta T \approx T_0 \times h/r_{\sun}. We suggest that this effect largely explains the systematic temperature increase in the upper corona reported in recent studies (e.g. by Sturrock et al., Wheatland et al., or Priest et al.), rather than being an intrinsic signature of a coronal heating mechanism.Comment: 7 pages, 3 figures.

Satisfacción del usuario externo en el servicio de odontología del Centro de Salud José Olaya – Chiclayo

La investigación se realizó con el objetivo de determinar el nivel de satisfacción de los usuarios en cuanto a la atención que se ofrece en el servicio odontológico del Centro de Salud José Olaya. El estudio fue descriptivo con un diseño no experimental. La población muestral estuvo constituida por 214 pacientes y se utilizó un muestreo no probabilístico, Se aplicó como Técnica la encuesta y como instrumentos de recolección de datos el cuestionario SERVQUAL adaptado al ámbito odontológico y modificado para establecimientos de salud y servicios médicos de apoyo, el cual consta de dos secciones, el primero recoge la información relacionada a las expectativas de los pacientes y el segundo, recoge la información relacionada a las percepciones. A la vez cada uno contiene 22 ítems, con una valoración del 1 al 7. Después del procesamiento de la información y haciendo uso de la estadística descriptiva se obtuvo un nivel de satisfacción regular de 55 %, con la atención que se brinda en dicho servicio, este porcentaje nos indica que se está en una fase de aceptación por parte del usuario externo, Se encontró un 88% de satisfacción baja en la dimensión fiabilidad, la dimensión capacidad de respuesta con un 73% de satisfacción regular; al igual que en la dimensión seguridad con un 66%, la dimensión empatía con un 58% de satisfacción alta y la dimensión aspectos tangibles con un 56% presentó regular satisfacción. Concluyendo que el nivel de satisfacción de los usuarios externos atendidos en el servicio de odontología del Centro de Salud José Olaya durante los meses de octubre y noviembre del 2019 fue regular

Attacking Multiple Fronts: The Tuskegee Airmen as Pioneers of Military Integration

Military service has long been associated with citizenship, and blacks have been part of every American war since the founding of this nation. Five thousand fought in the Revolutionary War, 180,000 fought in segregated units during the Civil War, and 380,000 enrolled in World War One. Although black participation increased with each major conflict, only 42,000 of the blacks in World War One belonged to combat units, a result of 20th century racial tensions that turned opinion against the use of black soldiers. Segregation persisted within the military establishment, including military aviation, through World War Two. Within a span of ten years, however, the Army Air Corps moved from having no African Americans among its ranks to become the United States Air Force, boasting tens of thousands of African Americans serving in many specialty areas. This dramatic change was inspired in part by the actions of the people who trained at Tuskegee Army Airfield or who served in the units of the Tuskegee experiment, collectively known as the Tuskegee Airmen. Their demonstrated skill in combat operations, their direct action protests against segregation outside of combat, and their remarkable commitment to preservation of military efficiency and discipline despite prejudices in semi-integrated settings combined to undermine the foundational justifications of military segregation, paving the way for Executive Order 9981 and integration of the Air Force
