Valve for waste collection and storage

A method and valve apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment is presented. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undersirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect the fecal matter, scrub the waste collection area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, so the valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pads to a face of the piston with each actuation

Presidential Profiles: Race, Leadership Orientation, and Effectiveness

This dissertation study examined racial differences in leadership orientation and effectiveness at United States four year, public colleges and universities as self-perceived and as perceived by presidents, as a means to contribute to the literature on race leadership orientation and effectiveness. The quantitative study design is to determine significant relationships among University or College Presidents or Chancellors (UCPC) pertaining to their leadership frames and effectiveness using (Bolman and Deal 1991a, 1991b, 2003) four-frame leadership theory and Quinn (1988) competing values model. The study attempts to understand any distinct observations that may be present. This study will not be an attempt to either predict success or failure of presidents. The study is twofold: (a) to investigate the experiences of selected UCPCs in public and private institutions and (b) to present descriptive and trend data in order to develop a comprehensive profile of UCPCs black, white, and non-black non-white in higher education Understanding what factors these presidents considered to be success and failure within the context of leadership effectiveness is most important. The study explored how direct reports of the senior executive leadership team interacts with UCPCs and to what extent, if any, are there statistically significant differences based on race. The study also examine factors (Gender, Race, Years in Current Job, Total Years of Management Experience, Age, and Educational Level) which influence the president and his/her senior leadership team. In addition, no significant differences were found between black and non-black leadership characteristics, which stands in contrast to extant research-supported evidence. The study employed survey methodology to gather information about presidents’ self- perception of their leadership orientations and perceptions of leadership effectiveness of the presidents’ performance as reported by his/her direct report staff. Information on demographic characteristics was gathered to determine if they explained variations in the responses. The Bolman and Deal Leadership Orientation Questionnaires for SELF and Quinn’s Competing Values Leadership Instrument (CVLI) were employed to gather the information. This study analyzed the 91 UCPCs and 38 subordinate participants from executive leadership positions in higher education institutions. Identified race by the participants in the study included (UCPCs/DRs): 74/25 White Non-Hispanic, 5/2 Black Non-Hispanic, 0/4 Hispanic, 1/0 Asian, 0/0 Native Hawaiian, 1/0 American Indian or Alaskan Native, 1/0 Two or More Races, 0/0 Race/Ethnicity Unknown, and 1/0 Other

Flight and wind-tunnel calibrations of a flush airdata sensor at high angles of attack and sideslip and at supersonic Mach numbers

A nonintrusive airdata-sensing system was calibrated in flight and wind-tunnel experiments to an angle of attack of 70 deg and to angles of sideslip of +/- 15 deg. Flight-calibration data have also been obtained to Mach 1.2. The sensor, known as the flush airdata sensor, was installed on the nosecap of an F-18 aircraft for flight tests and on a full-scale F-18 forebody for wind-tunnel tests. Flight tests occurred at the NASA Dryden Flight Research Facility, Edwards, California, using the F-18 High Alpha Research Vehicle. Wind-tunnel tests were conducted in the 30- by 60-ft wind tunnel at the NASA LaRC, Hampton, Virginia. The sensor consisted of 23 flush-mounted pressure ports arranged in concentric circles and located within 1.75 in. of the tip of the nosecap. An overdetermined mathematical model was used to relate the pressure measurements to the local airdata quantities. The mathematical model was based on potential flow over a sphere and was empirically adjusted based on flight and wind-tunnel data. For quasi-steady maneuvering, the mathematical model worked well throughout the subsonic, transonic, and low supersonic flight regimes. The model also worked well throughout the angles-of-attack and -sideslip regions studied

Practical applications of remote sensing technology

Land managers increasingly are becoming dependent upon remote sensing and automated analysis techniques for information gathering and synthesis. Remote sensing and geographic information system (GIS) techniques provide quick and economical information gathering for large areas. The outputs of remote sensing classification and analysis are most effective when combined with a total natural resources data base within the capabilities of a computerized GIS. Some examples are presented of the successes, as well as the problems, in integrating remote sensing and geographic information systems. The need to exploit remotely sensed data and the potential that geographic information systems offer for managing and analyzing such data continues to grow. New microcomputers with vastly enlarged memory, multi-fold increases in operating speed and storage capacity that was previously available only on mainframe computers are a reality. Improved raster GIS software systems have been developed for these high performance microcomputers. Vector GIS systems previously reserved for mini and mainframe systems are available to operate on these enhanced microcomputers. One of the more exciting areas that is beginning to emerge is the integration of both raster and vector formats on a single computer screen. This technology will allow satellite imagery or digital aerial photography to be presented as a background to a vector display

Apparatus for waste collection and storage

An apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect fecal matter, scrub the waste collector area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation

Review of the Oligocene Cetacea

Early in the Oligocene Epoch, Cetacea of the primitive suborder Archaeoceti had already declined sharply from their apparent abundance in Eocene seas. By the beginning of the Miocene, archaeocetes are known to have survived only in the northeast Atlantic and southwest Pacific Oceans. Concurrently with this decline, the first members of the suborders Odontoceti and Mysticeti appeared. They are known from only a few specimens, mostly in upper Oligocene deposits, on both coasts of North America, in Germany, Austria, Italy, the Caucasus, Azerbaijan, Australia, and New Zealand. Two important odontocete genera, Agorophius and Xenorophus, come from beds that are probably no older than late Oligocene and that are certainly not as old as Eocene, where these genera have previously been placed. The wide distribution of known Oligocene Cetacea, especially their presence in Australia and New Zealand, indicates the probable existence of a cosmopolitan cetacean fauna by the end of Oligocene time. The Oligocene Odontoceti are represented by Agorophius and related forms and by the Squalodontidae. Several types of skull telescoping are shown by contemporary members of these groups. Recently collected squalodont skulls from the Oligocene of South Carolina show differences in the pattern of cranial bones that may be ontogenetic. Some toothed whales have morphologic features that have led to their being assigned variously to Archaeoceti and Mysticeti because they are regarded as representing a transitional stage between the two suborders. These forms are all of late Oligocene age; they cannot be mysticete ancestors because true Mysticeti are known from middle Oligocene deposits

\u3ci\u3ePanthera atrox\u3c/i\u3e (Mammalia: Felidae) from Central Alaska

A lower jaw of the large Pleistocene cat Panthera atrox (Leidy) was found on an alluvial flat near the mouth of Lost Chicken Creek, about 180 miles northeast of Fairbanks, Alaska. It was probably washed out of carbonaceous silt deposits which, in the adjacent area, have also yielded bones of Equus, Bison, Rangifer, Cervus, and Elephantidae. The Panthera jaw falls within the size range of the series from Rancho La Brea, California, and differs from Rancho La Brea specimens only in a few characteristics. P. atrox appears to have been significantly larger than extinct or modern Asian tigers. Despite continuity of the American and Asian land masses at times during the late Pleistocene, present evidence indicates discontinuity between the populations of great cats on the two continents
