The Implementation Of A Plug-And-Play Satellite Bus, Maurice Martin, Don Fronterhouse, Jim Lyke

Small Satellite Conference

Several years ago, the Air Force Research Laboratory (AFRL) began a research program to understand the complexity of aerospace systems and how, through technology, it would be possible create them much faster. To underscore the ambitions of this work, we referred to this research as the pursuit of the “six-day” spacecraft. The six-day interval is marked starting with identification of a mission need and ending with a fieldable spacecraft ready to integrate onto a launch vehicle. This body of work culminated in the creation of a plug-and-play satellite bus (PnPSat) as a “clean-sheet” approach to spacecraft architecture. With PnPSat, we …

Geostationary Small Satellite For Operationally Responsive Space (Ors) Communications Missions, Frank Taylor, Bryce Carpenter, Johannes Hacker, John Hibbs, Zach Thicksten, Jason Hinkle

Small Satellite Conference

Existing military communication systems use large, very expensive, heavily tasked “national asset” communications satellites located in geostationary orbits, often supplemented by leased capabilities on commercial satellites. As data and voice communication needs have increased with the adoption of network-centric warfare operations, these assets may becoming increasingly oversubscribed and unavailable when needed by tactical warfighters. The Air Force has established an office of Operational Responsive Space (ORS) to address these and other challenges. The Geo Small Sat (GSS) concept is less complex than a LEO constellation system, employing only a single small UHF/L Band communications satellite launched by a small responsive …

The Challenges Of Developing An Operational Nanosatellite, David Homan, Quinn Young

Small Satellite Conference

Recent nanosatellite programs and studies of nanosatellites for operational missions have highlighted challenges that are unique to this spacecraft category. While each small satellite class has peculiar design challenges, nanosatellite development challenges are compounded by the unique niche that nanosatellites occupy and the current perception of hardware maturity levels available to support nanosatellite spacecraft. Recent experimental successes with microsatellite systems are allowing such spacecraft to rapidly move toward operational systems. This has produced a false perception that the same small, high TRL operational components and subsystems used in microsatellites will transition easily into the smaller nanosatellite designs. At the same …

Genomic Profiling Reveals An Alternate Mechanism For Hepatic Tumor Promotion By Perfluorooctanoic Acid In Rainbow Trout, Susan C. Tilton, Gayle A. Orner, Abby D. Benninghoff, Hillary M. Carpenter, Jerry D. Hendricks, Cliff B. Pereira, David E. Williams

Animal, Dairy, and Veterinary Science Faculty Publications

Background

Perfluorooctanoic acid (PFOA) is a potent hepatocarcinogen and peroxisome proliferator (PP) in rodents. Humans are not susceptible to peroxisome proliferation and are considered refractory to carcinogenesis by PPs. Previous studies with rainbow trout indicate they are also insensitive to peroxisome proliferation by the PP dehydroepiandrosterone (DHEA), but are still susceptible to enhanced hepatocarcinogenesis after chronic exposure.

Objectives

In this study, we used trout as a unique in vivo tumor model to study the potential for PFOA carcinogenesis in the absence of peroxisome proliferation compared with the structurally diverse PPs clofibrate (CLOF) and DHEA. Mechanisms of carcinogenesis were identified from …

Effect Of High Intensity Ultrasound On Crystallization Behavior Of Anhydrous Milk Fat, Silvana Martini, A. H. Suzuki, R. W. Hartel

Nutrition, Dietetics, and Food Sciences Faculty Publications

The need to eliminate trans-fatty acids from foods’ formulation resulted in the exploration of new lipid sources and alternative processing conditions that will improve the physicochemical characteristics and nutritional qualities of lipid-based foods. In general, the physicochemical characteristics of lipid networks depend on the microstructure and crystallization behavior of the system. The objective of this work was to use high intensity ultrasound (HIU) as an additional processing condition to alter the crystallization behavior of a lipid model system (anhydrous milk fat). Results show that HIU application not only decreases the induction time of crystallization (faster crystallization) at a constant crystallization …

Where Is 'Community' In Community Based Forestry?, Courtney G. Flint, A. E. Luloff, James C. Finley

Sociology, Social Work and Anthropology Faculty Publications

Community-based forestry and community-based natural resource management have become increasingly common terms in both the scientific and popular press. However, as with so many other concepts currently in vogue, rarely do studies invoking them incorporate either a grounded theoretical understanding or practical inclusion of the central term: community. Community emerges through communication and interaction among people who care about each other and the place they live. In its purest form, community is marked by its multiple and often conflicting perspectives. This article draws upon recent research experience with the Ford Foundation's community-based forestry initiative to illustrate the importance of solidly …

We compared the FRC from partial CO2 rebreathing with those of a nitrogen washout reference method. Materials and Methods: Using an approved animal protocol, general anesthesia was induced and maintained with propofol in six swine (38.8-50.8 kg). In both the mechanical lung analog and the animals, a partial CO2 rebreathing monitor (NICO2, Respironics Inc., Wallingford, CT) was placed in …

Ecology, Problem Framing And Local Land Use Controls: A Case Study Of Socio-Ecological Governance In Franklin County, Idaho, Alissa Salmore

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Due to the continuity of energy and material flows, the persistence of an ecological network necessarily includes a linking of ecological units from local and immediate to regional and broad-ranging scales. Humans are an integral part of ecosystems acting as resource consumers and agents of change, and all systems can be considered combined 'socio-ecological' systems. Where environmental and social systems lack coordination, mismatches between the temporal, spatial or functional scales at which these systems operate lead to resource use inefficiencies and the loss of ecosystem components and functioning. This case study of Franklin County, Idaho documents a recent land use …
