A Tradition of Sovereignty: Examining Tribal Sovereign Immunity in Bay Mills Indian Community v. Michigan
This commentary previews an upcoming Supreme Court case, Bay Mills Indian Community v. Michigan, in which the Court may decide whether the doctrine of Tribal Sovereign Immunity prohibits Michigan\u27s attempt to enjoin Indian gaming in the state or whether Congress expressly allowed the suit when passing the Indian Gaming Regulatory Act
Investigation of a high speed data handling system for use with multispectral aircraft scanners
A buffer memory data handling technique for use with multispectral aircraft scanners is presented which allows digital data generated at high data rates to be recorded on magnetic tape. A digital memory is used to temporarily store the data for subsequent recording at slower rates during the passive time of the scan line, thereby increasing the maximum data rate recording capability over real-time recording. Three possible implementations are described and the maximum data rate capability is defined in terms of the speed capability of the key hardware components. The maximum data rates can be used to define the maximum ground resolution achievable by a multispectral aircraft scanner using conventional data handling techniques
The role of the microprocessor in onboard image processing for the information adaptive system
The preliminary design of the Information Adaptive System is presented. The role of the microprocessor in the implementation of the individual processing elements is discussed. Particular emphasis is placed on multispectral image data processing
A design approach to real-time formatting of high speed multispectral image data
A design approach to formatting multispectral image data in real time at very high data rates is presented for future onboard processing applications. The approach employs a microprocessor-based alternating buffer memory configuration whose formatting function is completely programmable. Data are read from an output buffer in the desired format by applying the proper sequence of addresses to the buffer via a lookup table memory. Sensor data can be processed using this approach at rates limited by the buffer memory access time and the buffer switching process delay time. This design offers flexible high speed data processing and benefits from continuing increases in the performance of digital memories
The preservation of atmospheric nitrate in snow at Summit, Greenland
There is great interest in using nitrate NO3 isotopic composition in ice cores to track the history of precursor nitrogen oxides (NOx = NO + NO2) in the atmosphere. Nitrate NO3 however can be lost from the snow by surface processes, such as photolysis back to NOx upon exposure to sunlight, making it difficult to interpret records of NO3 as a tracer of atmospheric NOx loading. In a campaign consisting of two field seasons (May–June) at Summit, Greenland, high temporal frequency surface snow samples were collected and analyzed for the oxygen isotopic composition of NO3. The strong, linear relationship observed between the oxygen isotopes of NO3 in both 2010 and 2011, is difficult to explain in the presence of significant post depositional processing of NO3 unless several unrelated variables change in concert. Therefore, the isotopic signature of NO3 in the snow at Summit is most feasibly explained as preserved atmospheric NO3 deposition
ENERGY VALUE OF DE-OILED DISTILLERS GRAINS PLUS SOLUBLES IN BEEF CATTLE DIETS
Ethanol plants are centrifuging off oil from the thin stillage stream as it has added market value currently. The impact of oil removal on cattle performance has been minimally researched. Thus four trials, one growing, one digestion, and two feedlot, were designed to determine the energy and feeding value of de-oiled distillers grains in beef cattle diets.
In growing cattle diets, diet concentration of modified distillers grains plus solubles (MDGS) impacted cattle performance more than oil content. Ending BW, ADG, and G:F did not differ between cattle fed de-oiled or full fat MDGS, however cattle fed de-oiled MDGS had lower DMI than those fed full fat MDGS. No significant differences in fiber digestibility were observed between de-oiled and full fat MDGS treatments. The energy value of de-oiled MDGS in growing cattle diets was calculated to be 124% the value of corn.
In finishing steer diets, increasing diet concentrations of de-oiled MDGS increased G:F. However, decreasing MDGS fat content from 12.0% to 7.2% decreased steer performance by 3.4%. No significant interactions were observed when increasing concentrations of de-oiled wet distillers grains plus solubles (WDGS) were fed with steam flaked (SFC) or dry rolled corn (DRC). Comparison of steer performance when de-oiled and full fat WDGS are fed in SFC and DRC diets resulted in no significant differences also.
In growing and finishing diets small differences in cattle performance have been observed. Energy values for distillers grain in growing diets are still high with no improvements in fiber digestibility being observed. In finishing diets where distillers grains were fed at 30-35%, de-oiled distillers grains have 89% the feeding value of full fat distillers grain.

Role of the Pediatric Dental Provider in Human Papillomavirus (HPV) Education
Purpose: This study investigates knowledge about HPV and examines if pediatric dental providers should include HPV education for guardians of patients 10-18 years.
Methods: Legal guardians of 10-18 year-old patients of the Virginia Commonwealth University Pediatric Dental Clinic were enrolled in this prospective cohort study. Participants completed a baseline survey, were provided HPV education, completed an initial follow-up survey, and then completed a 6-month follow-up survey.
Results: A total of 54 participants completed the baseline and initial follow-up surveys and 17 completed the 6-month follow-up survey. The average number of correct responses was 3.4 of 6 knowledge questions, which significantly improved to 5.4 at follow-up (P\u3c.0001). The greatest increase in the percent responding correctly was regarding HPV and oropharyngeal cancer from 22% baseline to 91% at initial follow-up (P\u3c.0001). Regarding Stage of Change, 14 (23%) of those not initially in the Action group had improved at least 1 stage. At the 6-month follow-up, 3 (43%) guardians reported completing the HPV vaccine series.
Conclusions: These results demonstrate limited knowledge about HPV and highlight the pediatric dental provider’s ability to educate. Since the greatest knowledge gap pertained to HPV and oropharyngeal cancer, it is important for pediatric dental providers to increase their role in HPV education. As oral cancers are the purview of dentists, practitioners should be involved with their patients’ consideration of the HPV vaccine
