Implications of Alternative Missouri River Flows for Power Plants

The purpose of this paper is to discuss the potential impacts of low Missouri River flows on the power plants operating along the Missouri River and using the Missouri River for cooling water

Electrical Thermometers for Aircraft

Electrical thermometers commonly used on aircraft are the thermoelectric type for measuring engine-cylinder temperatures, the resistance type for measuring air temperatures, and the superheat meters of thermoelectric and resistance types for use on airships. These instruments are described and their advantages and disadvantages enumerated. Methods of testing these instruments and the performance to be expected from each are discussed. The field testing of engine-cylinder thermometers is treated in detail

Implications of Minimum Summer Water Releases from Gavins Point for Power Plants

The purpose of this study is to evaluate the potential impacts on power plants of minimum water releases from Gavins Point to the Missouri River as presented in the U.S. Army Corp of Engineers' (Corps) Master Manual (Corps 2004). The Corps regulates the flow of the Missouri River to support navigation and control flooding by controlling water releases from Gavins Point, the lowest of the six reservoirs

Zooplankton of the waters adjacent to the C.P. Crane Generating Station

Zooplankton populations in the Gunpowder River and its tributaries were sampled monthly from July 1979 to March 1980 in a continuation of similar studies begun in March 1979. Fourteen stations were sampled for mesozooplankton (202 ~m nets); six of these stations were also sampled for microzooplankton (concentration of pumped samples on 76 ~m netting)

Briefing Paper on the Demand for U.S. Commodity Exports and the Mississippi River: Past and Future

As part of the decision in evaluating the lock and dam upgrade on the Mississippi River, the U.S. Army Corps of Engineers (Corps) has contracted with various agricultural forecasting companies (most recently Sparks Companies, Inc.) to produce long range projections of agricultural exports and the implied demand for Mississippi River transportation services. The future demand for barge transportation services is a key component in evaluating the value of lock and dam upgrades. In this context, it is important to understand the volume of U.S. exports that utilize the river versus other modes of transportation

White matter changes and confrontation naming in retired aging national football league athletes

Using diffusion tensor imaging (DTI), we assessed the relationship of white matter integrity and performance on the Boston Naming Test (BNT) in a group of retired professional football players and a control group. We examined correlations between fractional anisotropy (FA) and mean diffusivity (MD) with BNT T-scores in an unbiased voxelwise analysis processed with tract-based spatial statistics (TBSS). We also analyzed the DTI data by grouping voxels together as white matter tracts and testing each tract's association with BNT T-scores. Significant voxelwise correlations between FA and BNT performance were only seen in the retired football players (p < 0.02). Two tracts had mean FA values that significantly correlated with BNT performance: forceps minor and forceps major. White matter integrity is important for distributed cognitive processes, and disruption correlates with diminished performance in athletes exposed to concussive and subconcussive brain injuries, but not in controls without such exposure

Debris-Collecting Vacuum Machine with Grounded Safety System and Associated Methods

A debris collection machine includes a vacuum system (including a suction source operable to provide suction for pulling debris into a receptacle), a ground reference portion, a ground test portion, and a ground-checking module. The ground reference portion is electrically coupled with an electrically grounded reference point, and the ground test portion is electrically coupled with a portion of the vacuum system. The ground-checking module determines a resistance between from the ground reference portion and the ground test portion and prevents or terminates operation of the suction source of the vacuum system when the resistance exceeds a predetermined threshold value, e.g., which may correspond to a risk condition of spark generation that could ignite material in the receptacle
