Description

The current push to develop small satellites, the need for formation flying constellations, and the desire to replace reaction control wheels have resulted in the need for thrusters that can deliver very small impulse bits. The required thrusters are much smaller than those available today, so new technologies will have to be developed. In Phase I, Ultramet focused on the development of catalysts that could be scaled down to the dimensions required for such small thrusters. To facilitate testing of these catalysts, Tridyne was used as the propellant, and several dozen catalyst beds were tested in a 5-lbf test engine. Several of the catalyst beds tested showed faster temperature rises and higher steady-state temperatures than a similar sized bed of Shell-405. For all of the Ultramet catalysts, the supports were monolithic materials that could easily be scaled down for use in microthrusters. Phase II will build on this technology, and enable the resulting catalysts to be used with other propellants, such as hydrazine or HAN-based monopropellants.

Description

The CAGES program (Comparative Assessment of Gulf Estuarine Systems) is designed to examine the differences between estuarine ecosystems and investigate why some are more productive than others. The program focuses on estuarine areas important to commercial fisheries and includes data on commercial finfish and invertebrate species, as well as other species commonly captured in trawl sampling. This Mississippi dataset is a subset of the CAGES Relational Database which is a compilation of fishery-independent data contributed by natural resource agencies of the Gulf States (Texas, Louisiana, Mississippi, Alabama, and Florida). This data set includes data from trawls collected by the Mississippi Department of Marine Resources and the University of Southern Mississippi's Gulf Coast Research Laboratory (MDMR/GCRL), as well as associated hydrographic data. Trawl data were used to calculate CPUE (catch per unit effort) at each station for the years 1973 through 2005.

Description

Fission-based power systems are anticipated for various planetary surface human base applications with power levels of 30?100+ kWe. The development of high temperature, high efficiency heat exchangers, turbines, and pumps is critical for next-generation nuclear power and space propulsion systems. High temperature heat exchangers are required for nuclear reactors to operate above 1000 K and take advantage of improved Brayton cycle efficiency at high inlet temperatures. In previous work for the Department of Energy involving fusion reactor components, Ultramet demonstrated the capability of an innovative heat exchanger composed of a highly porous, open-cell refractory metal foam coolant channel enclosed within a solid refractory metal shell of the same material. High heat flux testing with helium coolant was performed at the Sandia National Laboratories Plasma Materials Test Facility. A component survived heat flux levels up to 22.36 MW/m2 (2236 W/cm2). The turbulence created by flowing helium coolant through highly porous open-cell foam dramatically increased heat transfer relative to a conventional open coolant channel. Foam core heat exchanger technology is anticipated to substantially improve power conversion efficiency of liquid metal-to-gas, high temperature heat exchangers for fission surface power systems. Ultramet proposes to team with Sandia to design a component and demonstrate initial feasibility.

Description

This is a catch-all placeholder for on-going, completed, and future projects assessing marine growth of juvenile salmon using measures of the hormone IGF1. This work is conducted from California through Oregon, Washington, BC and Alaska. The work has been supported by Bonneville Power (see juvenile salmon ocean ecology and Columbia River Plume (actually the same project)) since 2000 (~$83k/year), BIOP since 2006 (~$75k/year), the Pacific Salmon Commission (2007 - 2008, $43k/year), NOAA FATE (2009 - 2010, $100k/year) and recently received a new grant from the Pacific Salmon Commission (2012 - 2014, $57k/year). A proposal with the North Pacific Research Board for work in Alaska is pending. The overall goals of the project are to elucidate the marine ecology of juvenile salmon in the Pacific Ocean, and to develop salmon growth as an ecosystem indicator for the NE Pacific, including the California Current. This database listing is incomplete, and current budget numbers for BIOP (FY12) and PSC (FY12) are not in the system and preclude adding budget details. The data inventory page is confusing; it is difficult to discern what is actually being asked for. This consists of a salmon ID number from a research survey and an IGF value measured from that fish. This data becomes more useful when other attributes of the salmon (species, size, genetics) and the sampling location (lat, long, temp, sal) are included. Currently there is data from approximately 30 surveys scattered among various Excel spreadsheets with differing amounts of ancillary data depending on how thoroughly the data has been worked up for reports or presentations.

Description

This hunt plan initiates the effort to manage Parker River National Wildlife Refuges whitetailed deer population at a level commensurate with the habitat. This action will provide a wildlifedependent recreational opportunity for the hunting public to harvest surplus animals. As deer numbers are lowered, the potential threat to public and employee health and safety from Lyme disease will diminish. The hunt program has been deemed compatible with the purposes of the refuge, and will only have minimal impact on other existing uses. The implementation of a deer hunting program on portions of the refuge will increase the opportunities for the visiting public. Currently the refuge provides programs for bird watching, beachuse, hiking trails, bicycling, guided tour groups, fishing, and outdoor education. An Environmental Assessment, Finding of No Significant Impact, Section 7 Evaluation Form, Compatibility Determination Form, and information about trends in deer population on the refuge are included.

Description

This protocol framework provides guidance for conducting inventories or monitoring surveys of waterbird habitat conditions and use at local scale in a way that will allow analysis of multiple sites from multiple regions in the Refuge System. This protocol provides a framework for rapidly assessing local habitat conditions and quantifying use of wetlands by waterfowl, shorebirds, and wading birds hereafter referred to as waterbirds during nonbreeding periods. The majority of survey techniques described herein involve wholewetland visual assessments of habitat conditions or counts of waterbirds conducted from the wetland perimeter. This protocol framework was developed as part of the Integrated Waterbird Management and Monitoring IWMM Initiative, a largescale waterbird habitat conservation strategy currently focused on the U.S. Fish and Wildlife Services USFWS Regions 3, 4, and 5. A primary purpose of this protocol is to standardize waterbird and habitat monitoring during the nonbreeding period at a localscale. Resulting data can then be compiled and analyzed across broader geographic units. IWMM is a collaborative effort including the USFWS, the U.S. Geological Survey, the States, Ducks Unlimited, and other nongovernmental agencies. The content and structure of the protocols described below follows standards set forth in the U.S. Fish and Wildlife Services How to Develop Survey Protocols: a Handbook Version 1.0. Each of eight elements is addressed, including a protocol introduction, sampling design, field methods, data management, analysis, reporting, personnel requirements and training, operational requirements, and references. Additionally, a series of standard operating procedures provides greater detail on recommended methods and technical aspects of this protocol. Data entry, archival, and multiscale analysis are handled through an online database that is part of the Avian Knowledge Network. When their management objectives and information needs are similar, other USFWS Regions and partners are encouraged to use this framework to develop sitespecific guidance for their waterbird and habitat condition surveys.

Description

Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2010 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.

Description

This Phase I SBIR proposal seeks funding to develop a radiation-hardened circuit architecture to achieve SEU and SEL immunity by using delay-insensitive asynchronous logic, and to demonstrate its feasibility, effectiveness, and efficiency. Further, early studies reveal that an operational temperature range of 2K to 400K will be highly feasible. Delay-insensitive asynchronous logic removes the concept of a global clock by incorporating handshaking protocols to control the circuit. The handshaking protocols allows for flexible timing requirements, high power efficiency, and low noise/emission generation. The flexible timing nature of delay-insensitive logic makes this type of circuits an excellent candidate for mitigating radiation effects in digital electronics. Compared to the existing radiation-hardening techniques, the proposed solution has several substantial benefits including cost efficiency, SEU/SEL immunity without weak points, and the ability to retain data during power cycling while mitigating SEL. In addition, significantly improved supply voltage variation sustainability and security against power-based side-channel attacks can also be achieved.

Description

A Space Communications and Navigation (SCaN) flight experiment will demonstrate Next Generation Navigation Techniques and Advance SDR/STRS Communications Technology to TRL-7. Scintillation-hardening techniques will be applied to an open-source waveform ported to the SCaN platform. This will result in improved GPS navigation during geomagnetic storms. The ported waveform will be STRS-compliant and open source. It will provide a validation of the STRS architecture and software defined radio technology for space applications. While operational, the waveform will autonomously detect scintillation and automatically switch into a data collection mode for relaying the GPS samples to the SCaN avionics subsystem for later transmission to White Sands. The open-source, STRS-compliant waveform software and GB of GPS scintillation data will be enduring products of the flight demonstration. The STRS infrastructure will be expanded with the STRS tool kit produced during this project. The STRS tool kit will be similar to the OSSIE tool kit for the SCA, providing automatic code generation of STRS wrappers and interfaces. An eclipse-based framework will provide drag-and-drop of components for developing STRS-compliant software.
