Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh

Publications

Investigations of aircrew sustained operations (SUSOPS) have been criticized for employing tasks with no apparent external validity. Because measures obtained directly from aviators flying high-performance aircraft are difficult to obtain, a laboratory compromise is needed. High-fidelity flight simulators used for aircrew training offer the most realistic simulation, but their availability is limited. Personal computer-based flight simulators may provide adequate simulation in, the laboratory at a reasonable cost. This report describes a representative research protocol using a commercially available flight simulator during a simulated aircrew SUSOP.

Biodegradation Of Dichloromethane And Its Utilization As A Growth Substrate Under Methanogenic Conditions, David L. Freedman, James M. Gossett

Publications

Biodegradation of dichloromethane (DCM) to environmentally acceptable products was demonstrated under methanogenic conditions (35 degrees C). When DCM was supplied to enrichment cultures as the sole organic compound at a low enough concentration to avoid inhibition of methanogenesis, the molar ratio of CH4 formed to DCM consumed (0.473) was very close to the amount predicted by stoichiometric conservation of electrons. DCM degradation was also demonstrated when methanogenesis was partially inhibited (with 0.5 to 1.5 mM 2-bromoethanesulfonate or approximately 2 mM DCM) or completely stopped (with 50 to 55.5 mM 2-bromoethanesulfonate). Addition of a eubacterial inhibitor (vancomycin, 100 mg/liter) greatly reduced …

Approaching Mechanization Of Plant Micropropagation, Jeffrey Adelberg, R E. Young, A Hale, N D. Camper

Publications

Investigations of materials and methods for growing plant tissue in a continual-flow, liquid nutrient medium as an alternative to semisolid agar medium have been made. Enhanced growth of plant tissue on microporous
polypropylene membranes floating on a liquid nutrient has been demonstrated. Moreover, in vitro plantlets on the microporous membrane are free from entanglement with the support matrix and readily available to mechanized
handling. Trained growth of plantlets through polypropylene netting shows potential for mechanization by mass handling (separation, singulation, and transfer) of plant tissue cultures.

Visions For Greater Fremont Strategic Action Plan, Center For Public Affairs Research (Cpar)

Publications

The city of Fremont, Nebraska, has a proud history beginning with its founding in 1856. Wagon trails that once went through the town were soon transformed into railroads, contributing to the industrialization of the city before the turn of the century.

Today, Fremont is a city of 24,000 people. Although the population has remained relatively stable over the past 30 years, the economy has continued to grow. The City of Fremont, the Fremont Area Chamber of Commerce, and the Fremont Chamber Industrial Foundation have been actively promoting growth and development during the last decade. Although the 1980s were dominated by …

Omaha Conditions Survey: 1990, Center For Public Affairs Research (Cpar)

Publications

This report summarizes responses for the North Omaha sample; findings from the metropolitan sample are presented in a separate report series. After a look at the demographic characteristics of the 200 adult respondents, the report examines the North Omaha area's quality of life, employment, and housing conditions. Next, ratings of the best and worst facets of life in the Omaha area are highlighted. The fourth section of the report provides details on North Omahans' satisfaction with a variety of services, facilities and programs. The final two sections focus in greater detail on two issues - labor force experiences and crime …

Biological Reductive Dechlorination Of Tetrachloroethylene And Trichloroethylene To Ethylene Under Methanogenic Conditions, David L. Freedman, James M. Gossett

Publications

A biological process for remediation of groundwater contaminated with tetrachloroethylene (PCE) and trichloroethylene (TCE) can only be applied if the transformation products are environmentally acceptable. Studies with enrichment cultures of PCE- and TCE-degrading microorganisms provide evidence that, under methanogenic conditions, mixed cultures are able to completely dechlorinate PCE and TCE to ethylene, a product which is environmentally acceptable. Radiotracer studies with [14C]PCE indicated that [14C]ethylene was the terminal product; significant conversion to 14CO2 or 14CH4 was not observed. The rate-limiting step in the pathway appeared to be conversion of vinyl chloride to ethylene. To sustain reductive dechlorination of PCE and …

The Santee Canal Sanctuary - Part Ii, Mark M. Newell

Publications

The Old Santee Canal Sanctuary encompasses the last vestiges of a once great industrial enterprise, a scant mile or more of a 23 mile long canal, the first of its kind in America. When this archaeological project was first contemplated it was not expected to yield much in terms of resources and data.
Part I of this project, the archaeological survey of Biggin Creek and the canal, revealed the existence of an extremely rich resource - the tide-lock, several vessels, earthen works and the remains of the tide-lock gates.
Much of Part II of the project, on which this paper …

Aerodynamic Forces On Flight Crew Helmets, Timothy A. Sestak, Richard M. Howard, Chester A. Heard

Publications

Wind tunnel tests were conducted to deter- mine the aerodynamic forces generated on aircrew flight helmets. Three helmets were tested: two used by aircrews flying ejection seat aircraft in the U.S. military, the Navy HGU-33/P and the Air Force HGU-53/P; and one prototype helmet of significantly different shape and volume. Axial and normal forces were measured through a range of pitch and yaw angles. It was found that large forces exist tending to promote helmet loss during ejection, and that simple modifications to the current helmet configurations can reduce those forces by as much as 40%. It is demonstrated that …

Transboundary Groundwaters: The Bellagio Draft Treaty, Robert D. Hayton, Albert E. Utton

Publications

Increasing populations and industrial and agricultural development worldwide are placing much greater demands on groundwater supplies. Many of these groundwater basins or aquifers underlie two or more countries and are, thus, international or transboundary. Withdrawals from one country can drain life-giving water from a neighboring country and, as a consequence, be the source of severe and protracted conflict. Unfortunately, international law and treaty practice are only at a beginning stage. With the goal of advancing international law and institutions on the matter, a multi-disciplinary group of specialists over an eight-year period have developed a draft international groundwater treaty.

The draft …

The Santee Canal Sanctuary - Part I, Joe J. Simmons Iii, Mark M. Newell

Publications

A proposed recreational and environment and historical interpretive park has been planned by the South Carolina Department of Parks, Recreation, and Tourism (PRT) jointly with the Santee Cooper Public Service Authority for the land along the west side of the Tailrace Canal extending between US Route 52 and Stoney Landing in Berkeley County, South Carolina. The Santee Canal Sanctuary, as it has been named, encompasses the southernmost ca. 2.0km (1.25mi) of the abandoned Santee Canal and Biggin Creek which essentially bisect the property longitudinally.
Development of the park and related construction activities dictated that archaeological investigations be executed. A …

S.T.A.R.T. Economic Development Action Step Packet - Community Image And Marketing, Center For Public Affairs Research (Cpar)

Publications

Lack of a clear community image, or the presence of a negative or ambivalent image, may emerge during your S.T.A.R.T. Economic Development strategic planning sessions as a reason for economic difficulties. Image problems are often perceived as a major cause of declining sales, conflicts, residents shopping elsewhere, and young people leaving. Although a negative image may be only part of the reason for (or a product of) economic decline, it usually has some influence on the community economy. Image is manifest in feelings of pride or embarrassment about the community-its streets, houses, lawns, city buildings, and businesses. A lack of …
