This report presents findings from the 2015 Focus Groups on Sexual Assault Prevention and Response (2015 FGSAPR) study, which collected qualitative feedback from military members through focus groups using trained moderators to facilitate discussion on these topics. The 2015 FGSAPR was generated in response to ongoing National Defense Authorization Act (NDAA) requirements and guidance from a Secretary of Defense Directive (Secretary of Defense, 2014). The Defense Research, Surveys, and Statistics Center (RSSC) within the Defense Manpower Data Center (DMDC) was tasked with this effort. The goal of the 2015 FGSAPR effort was to engage in small group discussions with military members across the Department of Defense (DoD) on issues related to sexual assault. These structured discussions were designed to better understand how recent changes in sexual assault policies and programs have impacted military members and their workplace environment, as well as, address the military's climate of sexual assault response and prevention.

This tabulation volume presents findings from the 2015 QuickCompass of Sexual Assault Prevention and Response-Related Responders (2015 QSAPR) conducted by the Defense Research, Surveys, and Statistics Center (RSSC) within the Defense Manpower Data Center (DMDC). This survey was conducted at the request of the Sexual Assault Prevention and Response Office (SAPRO) as part of its ongoing evaluation efforts of Sexual Assault Prevention and Response (SAPR) programs towards sexual assault prevention and survivor support. The survey was designed to provide insights about SAPR responders-Sexual Assault Response Coordinators (SARCs) and Victims Advocates (VAs)-at military installations worldwide, to understand how effectively responders are trained for their positions, and their perceptions of how well their program is supported and executed.

The development of a wholly superconducting turboelectric distributed propulsion system presents unique opportunities for the aerospace industry. However, this transition from normally conducting systems to superconducting systems significantly increases the equipment complexity necessary to manage the electrical power systems. Due to the low technology readiness level (TRL) nature of all components and systems, current Turboelectric Distributed Propulsion (TeDP) technology developments are driven by an ambiguous set of system-level electrical integration standards for an airborne microgrid system (Figure 1). While multiple decades' worth of advancements are still required for concept realization, current system-level studies are necessary to focus the technology development, target specific technological shortcomings, and enable accurate prediction of concept feasibility and viability. An understanding of the performance sensitivity to operating voltages and an early definition of advantageous voltage regulation standards for unconventional airborne microgrids will allow for more accurate targeting of technology development. Propulsive power-rated microgrid systems necessitate the introduction of new aircraft distribution system voltage standards. All protection, distribution, control, power conversion, generation, and cryocooling equipment are affected by voltage regulation standards. Information on the desired operating voltage and voltage regulation is required to determine nominal and maximum currents for sizing distribution and fault isolation equipment, developing machine topologies and machine controls, and the physical attributes of all component shielding and insulation. Voltage impacts many components and system performance.

The Southwest CO2 Training Center was initiated in November 2009 in response to the need to develop a generation of workers with expertise in carbon capture, utilization and storage (CCUS). Three universities ran the Training Center cooperatively: New Mexico Tech, the University of Utah and Texas A&M University. The overall approach of the Training Center was to conduct education and outreach at a wide range of educational levels, including K-12 students and teachers, undergraduate and graduate students, professionals, and the general public. Key activities included: (1) Outreach targeted development of a video game (Carbon Bond) for middle-school students. (2) A summer program for high-school students. (3) Training for K-12 educators in Utah with a program by the Keystone center on the Climate Status and two offerings of a Masters of Science Teaching class at New Mexico Tech (NMT) on Climate and Carbon Sequestration. (3) Development and approval of an undergraduate curriculum for a concentration in CCUS for geology majors offered at the Earth and Environmental Science Department at NMT. This included a new course in Carbon Sequestration Science and a field course in Reservoir and Caprock Geology. (4) A new graduate-level course in CCUS was developed and offered via distance education to students at the University of Utah (U of U), NMT and the University of Texas at El Paso (UTEP). (5) Professional training via a reservoir modeling class, opening up the university courses to professionals, and conducting three webinars on outreach and public perception in CCUS.

The partition coefficients of Pt and other Pt Group Elements (PGE) between metal and silicate D(sub Metal-Silicate) and also between silicate minerals and silicate melts D(sub Metal-Silicate) are among the most challenging coefficients to obtain precisely. The PGE are highly siderophile elements (HSE) with D(sub Metal-Silicate) > 10(exp 3) due to the fact that their concentrations in silicates are very low (ppb to ppt range). Therefore, the analytical difficulty is increased by the possible presence of HSE-rich-nuggets in reduced silicate melts during experiments. These tiny HSE nuggets complicate the interpretation of measured HSE concentrations. If the HSE micro-nuggets are just sample artifacts, then their contributions should be removed before calculations of the final concentration. On the other hand, if they are produced during the quench, then they should be included in the analysis. We still don't understand the mechanism of nugget formation well. Are they formed during the quench by precipitation from precursor species dissolved homogeneously in the melts, or are they precipitated in situ at high temperature due to oversaturation. As these elements are important tracers of early planetary processes such as core formation, it is important to take up this analytical and experimental challenge. In the case of the Earth for example, chondritic relative abundances of the HSE in some mantle xenoliths have led to the concept of the 'late veneer' as a source of volatiles (such as water) and siderophiles in the silicate Earth. Silicate crystal/liquid fractionation is responsible for most, if not all, the HSE variation in the martian meteorite suites (SNC) and Pt is the element least affected by these fractionations. Therefore, in terms of reconstructing mantle HSE abundances for Mars, Pt becomes a very important player. In the present study, we have performed high temperature experiments under various redox conditions in order to determine the abundances of Pt, Au, Ru and Pd in minerals (olivine and diopside) and in silicate melts, but also to characterize the sizes, density and chemistry of HSE nuggets when present in the samples.

This effort is a detailed analysis of existing microelectronics and photonics test bed satellite data from one experiment, the bipolar test board, looking to improve our understanding of the enhanced low dose rate sensitivity (ELDRS) phenomenon. Over the past several years, extensive total dose irradiations of bipolar devices have demonstrated that many of these devices exhibited ELDRS. In sensitive bipolar transistors, ELDRS produced enhanced degradation of base current, resulting in enhanced gain degradation at dose rates <0.1 rd(Si)/s compared to similar transistors irradiated at dose rates >1 rd(Si)/s. This Technical Publication provides updated information about the test devices, the in-flight experiment, and both flight-and ground-based observations. Flight data are presented for the past 5 yr of the mission. These data are compared to ground-based data taken on devices from the same date code lots. Information about temperature fluctuations, power shutdowns, and other variables encountered during the space flight are documented.

A metallographic investigation has been made of the white layers formed on the bore surface of a fired Army and Navy cannon and those produced in gun steel specimens in laboratory where firing conditions were simulated. White layers are produced in laboratory specimens in reducing environments (e.g. methane gas) but not in argon or nitrogen and appear similar to those produced in the fired cannons. These are formed at the melting as well as lower temperatures. The effects of increase in the pressure of the environment appears first to aid the formation of white layers and furthermore to increase their thickness. These results and the earlier studies of the characterization of white layers from fired cannons suggests that carbon from the gaseous environment of the propellant combustion products and the pressures of gases have significant effects on the formation and growth of white layers. The white layers produced in the Navy cannon where NACO, low flame temperature propellant was used are compared with those produced in the Army cannons where high flame temperature propellant was used. These observations are also discussed. (Author)
