A Study Of Lymphocyte Subpopulations In Allergic And Asthmatic Patients, Cleora W. Barnwell
A Study Of Lymphocyte Subpopulations In Allergic And Asthmatic Patients, Cleora W. Barnwell
Retrospective Theses and Dissertations
The role of T and B lymphocytes in the human immune response has been studied in allergic and asthmatic patients by many investigators. Theories of suppressed cellular immunity have been reported showing decreased levels of T cells in peripheral blood. Elevated levels of IgE, an antibody, have been reported in these conditions, but not shown to be significant in distinguishing the different types of asthma. A double blind study of 19 allergic and 42 asthmatic individuals was conducted measuring T and B cell levels and IgE levels. The asthmatic group was subdivided into three types, intrinsic, extrinsic and mixed. The …
An Analysis Of The Effect Of Vibration Sensitivity On Hydrophone Design, George Dickson Hugus
An Analysis Of The Effect Of Vibration Sensitivity On Hydrophone Design, George Dickson Hugus
Retrospective Theses and Dissertations
Hydrophones used in the ocean produce spurious outputs due to vibration sensitivity which can severely degrade measurement accuracy. Sources of these vibration inputs are ocean surface waves, flow turbulence, and induced mechanical vibration. The hydrophone response to these vibrations is a noise voltage output. This can leave to a signal-to-noise problem particularly when measurements of small sound pressure levels are to be made. The objective of this thesis is to analyze the vibration response of three typical piezoelectric hydrophone sensor elements configurations and give design methods and constraints for reducing the problem of vibration sensitivity to an acceptable level. The …
Phosphorus Content And Release From Lake Sediments By Agitation, Hsien Ping Tang
Phosphorus Content And Release From Lake Sediments By Agitation, Hsien Ping Tang
Retrospective Theses and Dissertations
Man-made mixing in shallow lakes will resuspend bottom sediments and increase phosphorus concentration in the water body. The increase in phosphorus content may affect the lake productivity. During the course of this study, a better understanding of the water-sediment-phosphorus relationships of some shallow lakes in Central Florida was attempted. Column studies and batch experiments were used to investigate the effect of mechanical mixing on the release of phosphorus from bottom sediments collected from Lake Claire and Jessup. The particle size distribution and density distribution of the bottom sediments were studied and the release of phosphorus from each fraction was measured. …

The Design And Analysis Of A Unique Broadband Underwater Acoustic Source, Allan Mark Young
The Design And Analysis Of A Unique Broadband Underwater Acoustic Source, Allan Mark Young
Retrospective Theses and Dissertations
Requirements exist for a unique type of underwater acoustic source. The transducer is in the form of a linear array of discrete elements and is required to have a constants transmitting voltage response and carefully controlled directivity characteristics over a two octave bandwidth. A generalized model of a linear array of cylindrical piezoelectric ceramic acoustic radiators is developed and applied to the design of a prototype which operates over approximately one half of the required bandwidth. The prototype transducer was built and the measured results are compared with those predicted by the model. Recommendations are made for improving the performance …

A Computer Model For Comparison Of Flat Plate And Focusing Collectors For Solar Air Conditioning, H. B. Bucher
A Computer Model For Comparison Of Flat Plate And Focusing Collectors For Solar Air Conditioning, H. B. Bucher
Retrospective Theses and Dissertations
Two types of solar collecting systems are frequently employed--flat plate collectors with spectrally selective windows which trap sunlight with the "greenhouse effect" and focusing systems with curved mirrors which concentrate the sun's rays on an absorbing surface. The flat plate collector is the simpler of the two designs, but cannot readily provide temperatures as high as the focusing collector. Both of the collectors are candidates for absorption cycle solar air conditioning systems. This role dictates higher temperature than are normally required of solar collectors, particularly the flat plate design. Focusing systems of interest here are those which are fixed in …

A Case Study Of A Solar Augmented Heating System Versus A Solar Assisted Heat Pump, Louis P. Braleski
A Case Study Of A Solar Augmented Heating System Versus A Solar Assisted Heat Pump, Louis P. Braleski
Retrospective Theses and Dissertations
The usage and applications of solar energy are numerous; however, it's still in its infancy. The subject matter discusses two applications of solar energy, a "Solar Augmented Heated System" and a "Solar Assisted Heat Pump." The solar augmented system and the solar assisted system have the same components; however, the way they are used is of primary concern. A solar system in parallel with a heat pump is called "Solar Augmented Heating System" or in series with a heat pump is a "Solar Assisted Heat Pump." A 2000 ft2 house was utilized as the basis of the design. The heating …
An Investigation Into A Least Squares Method For Image Registration, Ernest William Cordon
An Investigation Into A Least Squares Method For Image Registration, Ernest William Cordon
Retrospective Theses and Dissertations
One of the problems associated with the automatic image processing of satellite photographs such as weather maps is the need for image registration; that is, the fitting of a map that has some translational and rotational bias to a known data base. This paper investigates a least square method of image registration using an image that has been converted into a boundary map with a pixel representation 1 for land, -1 for water and zero for cloud pixels. A sampled correlation array is constructed by shifting the weather map to locations on a given grid, centered around a sampled correlation …

Affinity Of Roadside Soils For Lead, Zinc, And Chromium, John H. Bell
Affinity Of Roadside Soils For Lead, Zinc, And Chromium, John H. Bell
Retrospective Theses and Dissertations
Highways are known to be a source of several toxic pollutants including the heavy metals lead, zinc and chromium. The need to manage highway runoff in a manner which reduces or eliminates the loading of heavy metals to receiving waters is evident, but more research has been required to develop cost-effective ways of meeting this need. Recent studies have indicated that the soil is a significant "sink" for heavy metals, allowing speculation that management practices which make use of the soil to retain metals from highway runoff should be employed. The purpose of this study is to evaluate the ability …

Differential Clotting Responses Of Rabbits To Injections Of Homogenates From Wild-Type And Tumorous-Head Drosophila Melanogaster, Alfred B. Cox
Differential Clotting Responses Of Rabbits To Injections Of Homogenates From Wild-Type And Tumorous-Head Drosophila Melanogaster, Alfred B. Cox
Retrospective Theses and Dissertations
Two groups of New Zealand white rabbits were injected with homogenates from Tumorous-head (Tuh) and Wild-type (WT) Drosophila melanogaster. A third group was used as a saline injected control. Blood collected in both acute and chronic studies was subjected to various hematological and post mortem studies. The Tuh injected group showed a five-fold increase in thrombocytes (blood platelets) over the controls and four-fold increase over the wild-type group. Reduced clotting times were noted from acute to chronic studies in both tumorous and wild-type studies; however, the magnitude of change between the two groups was insignificant. Investigations involving electrophoretic banding patterns, …

Reduction Of Lunchroom Noise And Other Behaviors Using Feedback And Group Contingent Reinforcement, Lottie Nell Larowe
Reduction Of Lunchroom Noise And Other Behaviors Using Feedback And Group Contingent Reinforcement, Lottie Nell Larowe
Retrospective Theses and Dissertations
Reduction of noise levels in an elementary school lunchroom was examined as a function of feedback and feedback plus reinforcement using group contingency procedures. Feedback consisted of signals from a traffic light with green indicating acceptable levels, yellow indicating slightly higher levels and red indicating unacceptable levels. Other behaviors, running, hitting, pushing and kicking, were measured incidentally. Results indicate that feedback plus reinforcement was effective in reducing noise levels. Feedback alone was also effective, but to a lesser degree. No response - response relationship was found to exist between noise level and the other behaviors.
Investigations Of Inertia Effects On An Infinite Solid Cylinder Due To Thermal Shock, Roland Vanderbilt Williams
Investigations Of Inertia Effects On An Infinite Solid Cylinder Due To Thermal Shock, Roland Vanderbilt Williams
Retrospective Theses and Dissertations
In this paper the effects of inertia are explored for the case of a thermal excitation applied on the surface of an infinitely long, solid circular cylinder. The linear uncoupled field equations for a homogeneous, isotropic, thermoelastic medium are used to derive the desired field equations of stress and displacement. The solution procedure included, first, the determination of the thermal boundary value problem from the energy equation which is identically satisfied for the uncoupled condition. Secondly, substitution of the strain-displacement relationships and the previously obtained thermal relation into the equilibrium equation containing inertial effects. The equilibrium equation is the only …

Digital Computer Analysis Of The Kinetic Response Of A Thermal Pressurized Water Reactor Power Plant, John F. Alburger
Digital Computer Analysis Of The Kinetic Response Of A Thermal Pressurized Water Reactor Power Plant, John F. Alburger
Retrospective Theses and Dissertations
A digital computer model has been developed to simulate the kinetic response of a thermal pressurized water reactor power plant. The program is capable of predicting core power and plant temperature variations which result from disturbances due to routine demand changes, control rod movement, and fission product poison transients as well as from transients during plausible accident situations. The development of the differential equations describing the influence of various primary plant components on the dynamics of the reactor have been heretofore documented in the literature. Finite difference equations facilitating the employment of a digital computer solution are fully derived. Confidence …

The Effects Of Halo Reduction Training On Individuals Varying In Cognitive Complexity, Kanchan S. Dandage
The Effects Of Halo Reduction Training On Individuals Varying In Cognitive Complexity, Kanchan S. Dandage
Retrospective Theses and Dissertations
The effects of training in halo reduction on cognitively complex and noncomplex individuals were studied. Three main hypotheses were tested: 1) There would be a significant negative relationship between cognitive complexity and halo. 2) Training would significantly reduce halo. 3) Training would significantly reduce the amount of halo in the ratings of cognitively noncomplex individuals, but not in the ratings of complex individuals. Forty undergraduate students were given a cognitive complexity test, and high and low complexity groups were identified. Subjects were randomly assigned to either the Training or the No-Training condition. The training groups participated in a lecture-discussion session …

A Review Of The Behavioral Techniques For Weight Reduction And Control In Adults, Carol Kerr Hardee
A Review Of The Behavioral Techniques For Weight Reduction And Control In Adults, Carol Kerr Hardee
Retrospective Theses and Dissertations
Obesity has been an increasing health problem in the United States. In recent years, extensive research has been on the use of behavioral techniques for weight control. Although traditional methods of treatment have not proven to be long-term, some behavioral studies have indicated maintenance. Findings indicated that self-control methods are most effective when they are presented through therapist instruction, which is gradually faded. A full behavioral program for weight control would also include basic adjunct procedures, i.e., monitoring of calories or food, exercise, stimulus control, and social reinforcement, as well as major behavioral methods such as covert sensitization, contracting, bibliotherapy, …
