Characterization And Staged Lagoon Treatment Of Swine Feedlot Waste, Abraham H. Loudermilk Jr.
Characterization And Staged Lagoon Treatment Of Swine Feedlot Waste, Abraham H. Loudermilk Jr.
Masters Theses
"Feedlot pollution is developing into a serious problem because of the trend toward intensive farming techniques and the increasing number of animals in confinement feeding operations. The purpose of this study was to characterize swine waste collected under a slotted feeding floor using a water-carriage system, and to evaluate the treatment of this waste in a staged lagoon system consisting of an anaerobic, a dual anaerobic-aerobic, and an aerobic lagoon. A small feeding floor unit capable of maintaining 3 separate groups of animals, and a pilot 3-lagoon system were designed, constructed, and operated for a period of approximately 4 months. …
High Speed Magnetically Supported Vehicles For Reducing Transportation's Degradations Of The Environment, Pravinchandra Shukla
High Speed Magnetically Supported Vehicles For Reducing Transportation's Degradations Of The Environment, Pravinchandra Shukla
Masters Theses
"The development of new techniques for higher speed transportation is desirable to satisfy the environmental, conservation, and economic requirements of society. Some of the important factors are presented for developing magnetically supported vehicles. A new method for improving the ratio of lift force to drag force is suggested and discussed. An application of the new technique to vehicles that would ride on a carpet of magnetism and would operate with less waste of energy is suggested "--Abstract, page ii.
Laboratory Studies Using Diffused Oxygen And Air For Hypolimnion Reaeration, Chin-Ming Pai
Laboratory Studies Using Diffused Oxygen And Air For Hypolimnion Reaeration, Chin-Ming Pai
Masters Theses
"The purposes of this research were to study the oxygen transfer rates and the oxygen transfer efficiencies of different types of aerators using different sources of oxygen in different types of water bodies, and to evaluate the number of diffusers required to be installed in a selected lake for hypolimnion aeration.
The experiments were conducted using a specially designed column. Four types of aerators, including a cylindrical stone diffuser, a spherical stone diffuser, and 2 ceramic diffusers (types A and B) which differed in pore size, were utilized as the aerators. The water bodies selected for the studies were Rolla …
Effect Of Glass Aggregates Upon Abrasiveness Of Asphaltic Mixtures, Dwarka Prasad Gupta
Effect Of Glass Aggregates Upon Abrasiveness Of Asphaltic Mixtures, Dwarka Prasad Gupta
Masters Theses
"The utilization of glass as an aggregate in asphaltic concrete pavements has been suggested as a means for reusing the increasing amounts of waste glass generated each year in the United States. Recent studies have shown that asphaltic mixtures containing glass aggregates can be designed to meet Marshall requirements for stability, flow and void content but the abrasiveness of mixtures containing glass aggregates had not been investigated. The objectives of this study were to develop a laboratory wear testing apparatus and compare the abrasiveness of asphaltic concrete mixtures using glass aggregates with the abrasiveness of mixtures using several different conventional …
A Study Of Right Turn On Red At Signalized Intersections, Ronald Duane Rains
A Study Of Right Turn On Red At Signalized Intersections, Ronald Duane Rains
Masters Theses
"Traffic engineers have discussed the controversial subject of allowing drivers to make a right-turn-on-red (R.T.O.R.) for many years. There have been many strong points given for and against allowing this movement.
Within this paper R.T.O.R. is discussed and conclusions are drawn for a research of literature and questionnaire survey.
Questionnaires were sent to ninety-three cities and all fifty states. Many valuable unwritten facts and opinions were received from the seventy city and thirty-six state traffic engineers that completed and returned the questionnaires.
It was determined that 63.8% of the states replying and 64.3% of the cities are presently utilizing R.T.O.R. …
