A Comparative Study Of Tensile Properties In Five Orthodontic Wires, Charles B. Mcdermott

Loma Linda University Electronic Theses, Dissertations & Projects

The tensile properties of .017 x .025" stainless steel. Multiphase, Blue Elgiloy, beta titanium, and Nitinol were tested and compared. All wires were tested in the "as received" condition. Fifteen samples of each type of wire were tested in order to determine the (1) modulus of elasticity, (2) .2% yield strength, (3) ultimate tensile strength, (4) percentage elongation and (5) maximum elastic deflection.

The modulus of elasticity and .2% yield strength are the most important properties to orthodontists because of their influence on the wire's stiffness, strength and range. The ratio of yield strength/modulus of elasticity, termed maximum elastic deflection, …

The Effect Of Exercise On Blood Flow In Pregnant Guinea Pigs, Marjorie Correll Sladek

Loma Linda University Electronic Theses, Dissertations & Projects

Recent investigations have shown decreased fetal weight in pregnant animals who were exercised regularly during pregnancy (Gilbert; Nelson; Longo, 1979; Terada, 1974). The purpose of this experimental study was to investigate fetal weight gain and measure blood flow in pregnant guinea pigs who were exercised 45 minutes per day; and thus answer the hypothesis that prolonged maternal exercise will cause decreased weight gain and decreased placental blood flow during pregnancy.

Twenty pregnant guinea pigs were exercised 15 minutes three times daily from 10 days gestation to approximately 60-62 days gestation (67 days being term) and were compared with 19 control …

Evaluation Of Blissymbolics As A Means Of Communication For The Deaf-Cerebral Palsy Population, Linda Howells

Loma Linda University Electronic Theses, Dissertations & Projects

The purposes of this study are:

1. To present the deaf-cerebral palsied population with a more functional means of communication.
2. To test the validity of using a non-vocal means of communication, Blissymbolics, when other more traditional methods of teaching communication skills (sign language or verbal communication) have been ineffective.

Blissymbolics has been found to be an effective means of communication with cerebral palsy children who are unable to develop verbal communication skills. However, there is no research in the use of Blissymbolics with the deaf-cerebral palsy population.

The traditional means of communication used with the nonspeaking deaf person (manual sign language) …

Characteristics And Practices Of Forensics Programs In Oregon Secondary Schools, Gregg T. Sylvester

Dissertations and Theses

Since 1943, six studies have been made of speech education in Oregon public schools. Several make reference to forensics, but none discuss this aspect of speech education in depth. As a result, the role of forensics in the schools has been assumed or denied. With the educational situation as it is, however, it is necessary that we have a greater understanding of the relationship between forensics and general speech education and language arts education.

Relationship Between Attribution And Conditions Of Reward In Children, Rhonda Miles

Graduate Theses

Thirty-eight third grade students were given the Intellectual Achievement Responsibility (lAR) Questionaire in order to determine their internal and external attribution scores. From those scores, 28 subjects were chosen to test the hypothesis by performing two separate but related tasks under the conditions of self-and external rewards. A correlation using the Pearson Product- Moment Correlation Coefficient was computed in order to determine the relation between the subject's attribution level and performance under different conditions of reward. The results showed a higher relationship between attribution and self-reward when self-reward followed external reward. A Chi square test was also computed to determine …

Biofeedback As An Alternative Treatment For Raynaud's Disease, Marianne Patricia Strawk

Graduate Theses

A case of Raynaud's disease, a functional disorder of the vascular system resulting in the hands and feet being abnormally sensitive to the vasoconstrictor influences of cold and emotional disturbance, was treated with thermal biofeedback in order to train the subject to increase her finger temperature and thus reduce the onset of Raynaud's attacks. In addition to biofeedback training to raise digital skin temperature, the experimental conditions included: no-feedback control phases to control for expectancy effects, and relaxation training combined with biofeedback to provide the subject with specific strategies to use when raising finger temperature. It was hypothesized that: 1) …

The Effect Of Individual Instruction Versus Group Instruction On Compliance In C.O.P.D. Patients, Renee L. Hills

Loma Linda University Electronic Theses, Dissertations & Projects

Because of the evolution of hospitals from general care to acute care centers, the need for more outpatient therapy programs had increased in an effort to aid patients in managing their health care at home. As a result, health care professionals were concerned with the extent to which patients would follow their medication and treatment programs. Marston estimated that approximately 30 to 35 percent of patients fail to follow their physicians' medical recommendations (Marston, 1970).

Discovering a means of insuring patient compliance was a prevalent concern in the nursing and medical professions. Previously we had attempted to blame noncompliance on …

A Comparison Of Boone-Prescott Content And Sequence Analysis Data Of Poorly And Highly Rated Clinician-Client Interactive Skills, Kathleen M. Noonan

Dissertations and Theses

One of the qualifications for being a competent speech and language clinician is to be skilled in interactional procedures within a clinic setting. A clinician's interactional skills are developed through training whereby one participates in several clinical settings with clients displaying a variety of speech, language and hearing disorders. Various evaluation methods, both subjective and objective, have been utilized in guiding the clinician towards interactional competency.

Interactional analysis systems have been designed to provide more objective feedback. The Boone-Prescott Content and Sequence Analysis System (B-P) is one of several such systems. Although this system has been found to be an …

Bioavailability Of Calcium, Fluoride And Iron In Mechanically-Deboned Beef Fed To Growing Rats, Kathryn Mclaughlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Weanling rats were fed diets containing raw lyophylized hand-deboned shank beef (HDS) supplemented with CaCO₃, retorted lyophylized mechanically deboned shank beef (MDS), or raw lyophylized MDS. Ca in the latter two diets originated from bone during the mechanical deboning process. Ca absorption, Ca retention, bone weight, and bone breaking strength were similar for comparative dietary levels of Ca regardless of the source. Bone ash and Ca content was significantly higher (P < .05) in the MDS 393 (3.93 g Ca/kg diet) diet and in the retorted MDS 460 diet compared with the HDS 488 diet. Relative biological values for the MDS diets calculated relative to the HDS diets ranged from 102 to 132 when the linear regression of Ca consumed, Ca retained, or dietary Ca level vs bone ash or bone Ca content was obtained. The retorted MDS 460 diet contained the highest Fe level and exhibited a lower percent absorption, terminal hemoglobin level, and liver Fe storage. Humerus F content increased as dietary F (also present from bone) level increased. Dietary F level did not determine humerus breaking strength.

An Investigation Of Observer Evaluation Accuracy Of Clinical Sessions, Douglas Scott Peterson

Dissertations and Theses

Student speech-language pathologists begin their academic preparation as observers. Observations of the clinical management session are for the purpose of providing student clinicians with insight into the management process by providing clinical models. To make observation experiences meaningful there must be some guiding framework which will demonstrate the significance of behaviors observed. The purpose of this investigation was to determine the effect Boone-Prescott Content and Sequence Analysis System (B-P) instruction had upon the accuracy of beginning student observation evaluations of clinical management sessions.
