Apparatus for aiding a pilot in avoiding a midair collision between aircraft
An apparatus for aiding a pilot in avoiding a midair collision between aircraft is described. A protected aircraft carries a transmitter, a transponder, a receiver, and a data processor; and an intruding cooperating aircraft carries a transponder. The transmitter of the protected aircraft continuously transmits a signal to the transponders of all intruding aircraft. The transponder of each of the intruding aircraft adds the altitude of the intruding aircraft to the signal and transmits it back to the receiver of the protected aircraft. The receiver selects only the signal from the most hazardous intruding aircraft and applies it to the data processor. From this selected signal the data processor determines the closing velocity between the protected and intruding aircraft, the range between the two aircraft, their altitude difference and the time to a possible collision
2009 Progress Report on the Economic Well-Being of Working Age People with Disabilities
This progress report on the prevalence rate, employment, poverty, and household income of working-age people with disabilities (ages 21-64) uses data from the 2008 and earlier Current Population Surveys – Annual Social and Economic Supplement (CPS-ASES, a.k.a. Annual Demographic Survey, Income Supplement, and March CPS). The CPS is the only data set that provides continuously-defined yearly information on the working-age population with disabilities since 1981

It\u27s a Whole New Ball Game: The Mitchell Report, Performance Enhancing Drugs, and Professional Sports
This dissertation investigates the findings of a congressional investigation into the use of performance enhancing drugs (PEDs) in Major League Baseball, known as the Mitchell Report. It analyzes the primary arguments presented in the report, the argument for integrity, role-models, and apology specifically, through the lens of governmentality and moral regulation. It argues that the report represents a distinct mode of governance that seeks to condemn PED use in a moralizing way. This mode of governance is characterized by its emergence from a variety of locations as opposed to the relatively simple use of the state and its legal apparatus. Importantly, one of those locations includes the individual subject who is urged to self-govern without the need of external threat or recourse. The dissertation also suggests that this mode of governance is inextricable linked to rhetoric and communication
Vertical transport dynamics of striped bass eggs
Eggs of the striped bass, Morone saxatilis (Walbaum), were obtained from the Eagle Bend Hatchery in Clinton, Tennessee. Terminal sinking velocities in static water were determined for live eggs of females from Norris and Chickamauga Reservoirs. A significant difference was indicated for egg terminal sinking velocity based on the lake origin of the female. It was not possible to determine the original strain of the females or whether hormone injections of females prior to spawning affected egg density. Terminal sinking velocity was found to be highly correlated with both egg diameter and the ratio of oil globule diameter to yolk diameter, but correlation was highest for the latter.
Terminal sinking velocities for stained eggs from Norris and Chickamauga females were also determined, and the vertical transport rates of these eggs were studied in laboratory flows. Experiments were conducted for six flow rates over smooth and rough substrates. Vertical transport rate was shown to be a function of egg density and the shear velocity of flow.
The relative number of eggs suspended under various flow conditions was determined and related to terminal egg sinking velocity and the shear velocity of flow. A method was developed by which the percentage of eggs suspended in natural stream flow may be estimated
