Compton scatter attenuation gamma ray spectrometer
A gamma ray spectrometer is described for use in intense radiation fields such as those in the vicinity of a rocket engine exhaust. A collimated radiation beam is Compton scattered toward shielded spectrometers to reduce the energy and intensity of the radiation and is energy selective among the spectrometers. The scattering targets are changeable to control the percentage of the radiation scattered. Sum-Compton coincidence techniques are employed for data selection
Simulation of meteorological satellite (METSAT) data using LANDSAT data
The information content which can be expected from the advanced very high resolution radiometer system, AVHRR, on the NOAA-6 satellite was assessed, and systematic techniques of data interpretation for use with meteorological satellite data were defined. In-house data from LANDSAT 2 and 3 were used to simulate the spatial, spectral, and sampling methods of the NOAA-6 satellite data
Trademarks and Private Environmental Governance
This Article examines the relationship between private environmental governance and trademark law. Over the past two decades, green trademarks and other forms of private governance have flourished in tandem with the retreat from national and international public law modalities of environmental regulation. The rising political opposition to environmental regulation partly accounts for this change. Also relevant is the rise of globalization, which due to jurisdictional and trade constraints has diminished the effective regulatory control countries have over products sold in their markets.
Private environmental governance is premised on consumers “voting with their wallets” by selecting products that reflect not just their instrumental preferences, but also their values. The potential of this form of private governance has not been realized, however, in part because consumers are often overwhelmed by information from multiple green trademarks with different standards or criteria. The resulting congestion of market information has undermined the communicative function of green trademarks that is essential to enabling consumers to make environmentally responsible choices.
For a variety of reasons, trademark law is premised on a narrowly prescribed role for trademarks that is poorly adapted to facilitating information-based forms of private governance. Instead, intramural battles over the scope of trademark rights—ignited by overreaching corporate branding strategies—have elevated a reactionary turn in trademark theory that reduces trademarks solely to identifying the specific source of a product or service. We argue that the normative ends of private environmental governance should factor into, though by no means determine, trademark policy
Two- and three-dimensional simulations of core-collapse supernovae with CHIMERA
Ascertaining the core-collapse supernova mechanism is a complex, and yet
unsolved, problem dependent on the interaction of general relativity,
hydrodynamics, neutrino transport, neutrino-matter interactions, and nuclear
equations of state and reaction kinetics. Ab initio modeling of core-collapse
supernovae and their nucleosynthetic outcomes requires care in the coupling and
approximations of the physical components. We have built our multi-physics
CHIMERA code for supernova modeling in 1-, 2-, and 3-D, using ray-by-ray
neutrino transport, approximate general relativity, and detailed neutrino and
nuclear physics. We discuss some early results from our current series of
exploding 2D simulations and our work to perform computationally tractable
simulations in 3D using the "Yin-Yang" grid.Comment: Proceedings of the 12th Symposium on Nuclei in the Cosmos. 5-12

The Challenges of Multimorbidity from the Patient Perspective
BACKGROUND
Although multiple co-occurring chronic illnesses within the same individual are increasingly common, few studies have examined the challenges of multimorbidity from the patient perspective.
OBJECTIVE
The aim of this study is to examine the self-management learning needs and willingness to see non-physician providers of patients with multimorbidity compared to patients with single chronic illnesses. DESIGN. This research is designed as a cross-sectional survey.
PARTICIPANTS
Based upon ICD-9 codes, patients from a single VHA healthcare system were stratified into multimorbidity clusters or groups with a single chronic illness from the corresponding cluster. Nonproportional sampling was used to randomly select 720 patients.
MEASUREMENTS
Demographic characteristics, functional status, number of contacts with healthcare providers, components of primary care, self-management learning needs, and willingness to see nonphysician providers.
RESULTS
Four hundred twenty-two patients returned surveys. A higher percentage of multimorbidity patients compared to single morbidity patients were "definitely" willing to learn all 22 self-management skills, of these only 2 were not significant. Compared to patients with single morbidity, a significantly higher percentage of patients with multimorbidity also reported that they were "definitely" willing to see 6 of 11 non-physician healthcare providers.
CONCLUSIONS
Self-management learning needs of multimorbidity patients are extensive, and their preferences are consistent with team-based primary care. Alternative methods of providing support and chronic illness care may be needed to meet the needs of these complex patients.US Department of Veterans Affairs (01-110, 02-197); Agency for Healthcare Research and Quality (K08 HS013008-02

Kinematic Analysis of Obstacle Clearance During Locomotion
This study investigated the effect of obstacles of different heights on the locomotion of 15 healthy subjects. The following parameters were studied: (1) the distance of the toe and heel markers from the obstacle during toe-off and heel contact, respectively, (2) the minimum clearance distance of the toe and heel markers, and (3) the angular displacements and velocities of the hip, knee, and ankle. Results show significant differences in joint angular kinematics and clearance distances as obstacle height increased. The kinematic and distance differences exhibited both strong linear and non-linear trends. Toe-off distance and heel contact distance did not change significantly with changes in obstacle height
