Big Gulp Gets Even Bigger: Effects of Apparent Mass and Momentum Flux on the Forces during Baleen Whale Feeding
The feeding behavior of the Balaenoptera physalus, or more commonly known as fin whales, is some of the most extreme and somewhat curious feeding techniques among mammals and other aquatic vertebrate animals. The specific process includes a lunge deep into the ocean, and large gulp of water to catch many krill at one dive. These dives are relatively short due to the high energy expenditure, most likely due to the high drag exerted on the animal during the process. However, this drag is even more significant than previously thought. Due to the effects of apparent mass and momentum flux, the overall force is much greater than previously modeled. By mathematically modeling these effects during the lunge feeding process, researchers can have a more accurate understanding of additional inertial factors of ellipsoids, thus giving a better understanding in airship design
Wild Bill Hickok Gets His Kicks: Expanding Collection Development Through Intentional Collaboration
Various cultural memory institutions ( academic libraries, history museums, public libraries, art museums, state agencies, even theme parks) in the metropolitan area around Springfield, Missouri, have been partnering and collaborating for decades in many ways. The collaboration was primarily intentional but at times organic or opportunistic, and revolved around a local history collection strategy. The collaborative efforts expanded geographically beginning with a local history museum and culminating with a partnership to document a legendary national highway from Chicago, Illinois, to Santa Monica, California. A shared central premise based on preserving and providing access to a city\u27s unique history and place has fostered enduring collaborative relationships

The Optical Design of CHARIS: An Exoplanet IFS for the Subaru Telescope
High-contrast imaging techniques now make possible both imaging and
spectroscopy of planets around nearby stars. We present the optical design for
the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS), a
lenslet-based, cryogenic integral field spectrograph (IFS) for imaging
exoplanets on the Subaru telescope. The IFS will provide spectral information
for 138x138 spatial elements over a 2.07 arcsec x 2.07 arcsec field of view
(FOV). CHARIS will operate in the near infrared (lambda = 1.15 - 2.5 microns)
and will feature two spectral resolution modes of R = 18 (low-res mode) and R =
73 (high-res mode). Taking advantage of the Subaru telescope adaptive optics
systems and coronagraphs (AO188 and SCExAO), CHARIS will provide sufficient
contrast to obtain spectra of young self-luminous Jupiter-mass exoplanets.
CHARIS will undergo CDR in October 2013 and is projected to have first light by
the end of 2015. We report here on the current optical design of CHARIS and its
unique innovations.Comment: 15 page

Coeur d'Alene Tribe Fisheries Program Research, Monitoring and Evaluation Plan; Implementation of Fisheries Enhancement Opportunities on the Coeur d'Alene Reservation, 1997-2002 Technical Report.
Westslope cutthroat trout (Oncorhynchus clarki lewisi) and bull trout (Salvelinus confluentus) are currently of special concern regionally and are important to the culture and subsistence needs of the Coeur d'Alene Tribe. The mission of the Coeur d'Alene Tribe Fisheries Program is to restore and maintain these native trout and the habitats that sustain them in order to provide subsistence harvest and recreational fishing opportunities for the Reservation community. The adfluvial life history strategy exhibited by westslope cutthroat and bull trout in the Lake Coeur d'Alene subbasin makes these fish susceptible to habitat degradation and competition in both lake and stream environments. Degraded habitat in Lake Coeur d'Alene and its associated streams and the introduction of exotic species has lead to the decline of westslope cutthroat and listing of bull trout under the endangered species act (Peters et al. 1998). Despite the effects of habitat degradation, several streams on the Reservation still maintain populations of westslope cutthroat trout, albeit in a suppressed condition (Table 1). The results of several early studies looking at fish population status and habitat condition on the Reservation (Graves et al. 1990; Lillengreen et al. 1993, 1996) lead the Tribe to aggressively pursue funding for habitat restoration under the Northwest Power Planning Council's (NWPPC) resident fish substitution program. Through these efforts, habitat restoration needs were identified and projects were initiated. The Coeur d'Alene Tribe Fisheries Program is currently involved in implementing stream habitat restoration projects, reducing the transport of sediment from upland sources, and monitoring fish populations in four watersheds on the Coeur d'Alene Reservation (Figure 1). Restoration projects have included riparian plantings, addition of large woody debris to streams, and complete channel reconstruction to restore historical natural channel forms. In addition, ponds have been constructed to trap sediment from rill and gully erosion associated with agricultural practices, and to provide flow enhancement and ameliorate elevated stream temperatures during the summer base flow period. The implementation of restoration efforts that target the key habitats and lifestages for resident westslope cutthroat trout on the Coeur d'Alene Reservation is one means the Tribe is using to partially mitigate for lost anadromous fisheries. In this context, restoration is consistent with the definition provided by Ebersole et al. (1997), who described stream restoration as the reexpression of habitat capacity in a stream system. At the reach scale, habitat capacity is affected by biotic (e.g., riparian vegetation) and physical (e.g., flooding) processes. Superimposed on the natural biotic and physical processes are anthropogenic stressors (e.g., logging, roads and grazing) that suppress habitat capacity and can result in simplified, degraded stream reaches. The effectiveness of habitat restoration, measured as an increase in native trout abundance, is dependent on reducing limiting factors (e.g., passage barriers, high water temperatures, sediment transport from source areas) in areas that are critical for spawning and rearing lifestages. This plan outlines a monitoring strategy to help determine the effectiveness of specific restoration/enhancement treatments and to track the status of trout populations in four target watersheds
The impact of face-to-face mental health consumer-led teaching on occupational therapy student empathy levels : Two group comparison design
Introduction
Australian and New Zealand accreditation standards for occupational therapy courses mandate consumer involvement in the design, delivery, and evaluation of courses. Consumer involvement in medical, dental, and nursing education has been evidenced as a factor for increasing student empathy. To date, there has been no known research on the impact of mental health consumer involvement on occupational therapy students' empathy. The aim of this study was to investigate if occupational therapy students who receive teaching from a mental health consumer demonstrate higher levels of empathy compared with students who receive teaching delivered by occupational therapy academics.
Methods
Pre–post, quasi experimental, two group comparison design was used to measure second-year student empathy pre and post a consumer-led teaching tutorial. Students (N = 217) were randomised into two groups across three university campuses: ‘teaching as usual group’ (control) or ‘consumer-led’ group (experimental group). The Jefferson Scale of Empathy was used to measure student empathy.
Results
N = 138 matched scales were returned. Little difference in empathy scales was detected between groups. The ‘consumer-led’ group increased for the empathy scale by 3.4(95% CI: 0.7,6.1, p = 0.014) but was not statistically significant compared to 1.3(95% CI: −1.0,3.5, p = 0.267) for the control group. Both groups scored highly on empathy.
Conclusion
This study found that occupational therapy students had pre-existing high levels of empathy. The challenge for future research is to identify appropriate ways to measure the impact of mental health consumer involvement on occupational therapy curriculum and students
Design and Functional Validation of a Mechanism for Dual-Spinning CubeSats
The mission of the Micro-sized Microwave Atmospheric Satellite (MicroMAS) is to collect useful atmospheric images using a miniature passive microwave radiometer payload hosted on a low-cost CubeSat platform. In order to collect this data, the microwave radiometer payload must rotate to scan the ground-track perpendicular to the satellite's direction of travel. A custom motor assembly was developed to facilitate the rotation of the payload while allowing the spacecraft bus to remained fixed in the local-vertical, local-horizontal (LVLH) frame for increased pointing accuracy. This paper describes the mechanism used to enable this dual-spinning operation for CubeSats, and the lessons learned during the design, fabrication, integration, and testing phases of the mechanism's development lifecycle
