Remote sensing in the mixing zone

Results to date of a study of the dispersion and diffusion mechanisms by which pollutants are transported in natural river courses. The mixing zone at several industrial sites was studied by both ground and remote sensing methods. The advantage of coordination of these two methods is highlighted. The results can be used in the establishment of definite and rational water quality guidelines and in the development of a sampling and surveillance program by governmental and private agencies.

Photographic quantification of water quality in mixing zones

The waste effluent mixing zone is defined as the extent of a receiving water body utilized to dilute a waste charge to a concentration characteristic of a totally mixed condition. Color IR photography was used in conjunction with suspended solids water samples to quantitatively delineate the mixing zone resulting from the discharge of a paper mill effluent. Digital scanning microdensitometer data were used to estimate and delineate suspended solids concentrations on the basis of a semiempirical model. Model background, development, and implementation are described. Results indicate that the method is as reliable as conventional surface measuring techniques and is, in fact, more detailed. The method has direct application to the establishment of water quality guidelines, the development of both governmental and private sampling and surveillance programs, and the development of design and location criteria for industrial and municipal waste effluent outfalls.

A study of light airplane pilot landing performance

The results of a total of 289 landings performed with a low-wing aircraft by a group of private pilots on long and short runways have been analyzed to determine the landing performance of these pilots. Both the long- and short-runway landings show significant variation from straight or uniformly curved trajectories, denoting considerable 'jockeying' on the part of the pilot during approach. The long-runway approach speeds were variable and higher than recommended. Considerable float followed by touchdown at speeds well above stall were noted. The short-runway landings were quite similar, except that approach speeds were slightly lower as a result of the use of two-thirds to full flaps, and touchdown occurred closer to the threshold.

Satellites for the citizen

Applications Technology Satellite ATS-F scheduled for launch in 1974 will be the last of its type sponsored by NASA. In the years that these satellites have served the practical needs of prototype development programs for space technology, immense benefits have accrued to the general public in the fields of communications, navigation, meteorology, and a host of related areas. If the public is to continue to benefit from this extremely successful series of launchings, private enterprise will have to assume the cost of future ATS experiments when NASA withdraws from the field.

An evaluation of Skylab habitability hardware

For effective mission performance, participants in space missions lasting 30-60 days or longer must be provided with hardware to accommodate their personal needs. Such habitability hardware was provided on Skylab. Equipment defined as habitability hardware was that equipment composing the food system, water system, sleep system, waste management system, personal hygiene system, trash management system, and entertainment equipment. Equipment not specifically defined as habitability hardware but which served that function were the Wardroom window, the exercise equipment, and the intercom system, which was occasionally used for private communications. All Skylab habitability hardware generally functioned as intended for the three missions, and most items could be considered as adequate concepts for future flights of similar duration. Specific components were criticized for their shortcomings.

The feasibility of a unified role for NASA regional dissemination centers and technology application teams

Insights and recommendations arising from a study of the feasibility of combining the NASA Regional Dissemination Center (RDC) and Technology Application Team (Tateam) roles to form Regional Application Centers (RADC's) are presented. The apparent convergence of the functions of RDC's and Tateams is demonstrated and strongly supportive of the primary recommendation that an applications function be added to those already being performed by the RDC's. The basis of a national network for technology transfer and public and private sector problem solving is shown to exist, the skeleton of which is an interactive network of Regional Application Centers and NASA Field Centers. The feasibility of developing and extending this network is considered and the detailed ramifications of so doing are discussed and the imperatives emphasized. It is hypothesized that such a national network could become relatively independent of NASA funding within five years.

Combining total energy and energy industrial center concepts to increase utilization efficiency of geothermal energy

Integrating energy production and energy consumption to produce a total energy system within an energy industrial center which would result in more power production from a given energy source and less pollution of the environment is discussed. Strong governmental support would be required for the crash drilling program necessary to implement these concepts. Cooperation among the federal agencies, power producers, and private industry would be essential in avoiding redundant and fruitless projects, and in exploiting most efficiently our geothermal resources.
