A Study Of The Relative Contributions Of Orally And Nasally Emitted Signals To Hyper-Nasal Speech., Milo Ellis Bishop

Speech and Hearing Sciences ETDs

The validity of The Oral Nasal Acoustic Ratio (Tonar) System as a means of obtaining data relevant to perceived nasality was established by comparing forward and backward play scale values with nasal/oral acoustic ratios computed by Tonar.

The acoustic characteristics of orally and nasally emitted signals and their relative contributions to the total speech signal were analyzed and considered within the framework of oral and nasal acoustic masking.

A passage free of nasal phonemes was read by 20 subjects with surgically repaired palatal clefts. A specially designed instrumentation system (Tonar) was used to separate the signals emerging from the oral …

The Effect Of Exercise On Metabolic Rate With Time In Overweight And Normal Weight Subjects, Roberta Jewell Keswick

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies in the Lome Linda University laboratory showed that obese subjects on an exercise program lost approximately one pound more per week as compared to a non-exercise group. Energy expenditure calculations of the exercise did not account for the total caloric deficit required to lose the additional pound. The present study was designed to investigate changes in BMR and metabolic rate with time for normal weight and overweight subjects involved in a practical exercise program. The relationship of changes in BMR and metabolic rate in coping with the problems of obesity were also studied.

Fifteen subjects, eight overweight and …

Mandibular Nerve Regeneration Through Solid And Canalized Bone And Plaster Grafts, Lawrence D. Day

Loma Linda University Electronic Theses, Dissertations & Projects

Utilizing an extra-oral approach and sterile technique, left mandibular ostectomy was performed on five miniature pigs. The segment removed was 3 cm long and included the inferior border, mandibular canal and, in some cases, apices of a molar tooth.

Bone and plaster grafts (one solid and one canalized of each) were used to fill these defects. The fifth was left with no graft.

The objective was to learn the effect of each of these procedures on regeneration of the mandibular nerve across the defect. It was hypothesized that canals through the grafts would facilitate regeneration.

X-rays were taken periodically. The …

Kinetic Studies Of The Cell Elongation Phenomenon In Etiolated Pisum Stem Segments, Grant M. Barkley

Masters Theses

The short-term growth response of etiolated pea stem segments (Pisum sativum L., var. Alaska) was investigated using a high-resolution growth recording device. The immediate effect of treatment with indoleacetic acid (IAA) is an inhibition of growth. This inhibition lasts about 10 minutes and then the rate of elongation rises abruptly to a new steady rate about 4 times the rate of elongation before auxin treatment. This rapid steady rate of elongation, however, continues for only about 22 minutes before declining suddenly to a lower steady rate of growth about 2 times the rate of elongation before the addition of auxin. …

Location And Relationships Of The Axes Governing Mandibular Condylar Movements : An Anatomical Research, Jean-Michel Cottè

Loma Linda University Electronic Theses, Dissertations & Projects

A practical method of research on cadaver specimen heads was designed from a systematic review of the existing literature in order to differentiate from conjecture the experimental proof of the axes of rotation of the condyles during mandibular border movements.

An anatomo-physiological study on eight human cadaver heads, using the gnathologic technique of Dr. R. Lee for recording mandibular movements, was done to study the intimate mechanism of the temporomandibular joints, with the hope of contributing support to this new method of recording.

It was established that rotational mandibular border movements are induced by hard structure topography of the temporomandibular …

A manual was prepared and evaluated for use by non-professional personnel in community nutrition education. Instruction and suggestions were given for organizing these classes and techniques outlined for food demonstrations. Material was written for lectures and tests on eight nutrition topics, with visual aid suggestions, recipes and "chatter" to accompany the recipes.

The material was tested by presenting three of the eight topics before audiences. Volunteer non-professional teacher-demonstrators gave the presentations which were evaluated by test scores from the audiences, by score forms from each teacher-demonstrator, and by evaluation sheets from the advisory committee.

On the basis of the evaluation, …

Histopathological Response Of The Human Tooth To An Intrapulpal Pin Implantation, Raymond W. Dolph

Loma Linda University Electronic Theses, Dissertations & Projects

This investigation was designed to serve as a research project directed toward the study of histopathological response of human teeth to the intentional implantation of threaded, stainless steel, gold plated pins into the vital pulp.

Pins of several types are currently used in several aspects of restorative and periodontal dentistry. In some cases there may be unintentional perforation of the dental pulp. In other cases it may be advantageous to purposely perforate the pulp for added retention. The purpose of this research is to help determine the reaction, possibilities, and prognosis of such technique.

Analgesic Effectiveness As Measured By A New Algesiometer, J. Raymond Wahlen

Loma Linda University Electronic Theses, Dissertations & Projects

A method of measuring the effectiveness of analgesics using a new instrument, known as the Algesiometer,* is described. The instrument, utilizing an electrical stimulus, produced an experimental pain when attached to the skin over the mid shaft of the tibia. The patient, who was experiencing a pathological pain, gradually increased the experimental stimulus, by turning a control rheostat, until it was equal in intensity to the pathological, or clinical, pain. The intensity of the stimulus was calculated in milliwatts and consisted of a rectangular wave pulsating direct current of approximately one millisecond duration and an interval of nineteen milliseconds.

The Reaction Of Dog Tongue To Syrijet Injections, Donald L. Peters

Loma Linda University Electronic Theses, Dissertations & Projects

Tissue response toward injection by a "fluid-pressure" type apparatus, the Mizzy Syrijet, was evaluated by using dogs as the experimental animal.

The tongue was the organ of choice because it's size is sufficient to allow for several injections without overlapping tissue responses. In addition the two halves of the tongue are anatomically separated by a median raphe, providing for further isolation of injections.

The animals were injected at 12, 24, 48, 72 and 96 hour intervals utilizing the Syrijet on the right side of the tongue and needle on the left. Needle injection served as control for the microscopic comparison. …

Correlation Of The Actual Position Of The Root Canal Filling In Human Teeth To Its Apparent Location On The Radiograph, Dominic J. Niccoli

Loma Linda University Electronic Theses, Dissertations & Projects

Human teeth mounted in individual plaster blocks were studied to determine the actual location of the root canal filling when it appears to be exactly at the radiographic apex. The original sample consisted of 109 teeth treated during endodontic technique class by junior dental students at Loma Linda University. In the most ideal manner possible, these teeth were radiographed on a flat surface with the x-ray tube perpendicular to the film and blocked tooth.

Five dentists examined the radiographs, and each one independently listed the canals he judged filled exactly to the radiographic apex. The investigator sorted out the choices …
