Intelligibility Of Speech Compared Through Two Limiter Compression Circuits, Lee M. Odell

Dissertations and Theses

Hearing aid manufacturers commonly engineer automatic gain control (AGC) circuits which are aimed at reducing sound tolerance problems and improving speech intelligibility among wearers. The most common type of AGC engineered is one utilizing a fast attack time. The present study was designed to evaluate the effects of both fast and slow attack times on the intelligibility of speech. Twenty-four normal hearing subjects listened to sixty pre-recorded sentences through two types of hearing aid circuits. Thirty sentences were modified by a fast attack AGC circuit, and thirty sentences were modified by a slow attack AGC. The subjects marked one of …

Practical Anticonvulasant Pharmacokinetics, R.B. David, L.K. Garrettson

MCV/Q, Medical College of Virginia Quarterly

Pharmacokinetics is that area of pharmacology concerned with the absorption, distribution, metabolism, and elimination of drugs. The processes by which absorption, distribution, and elimination take place are referred to as unit processes. These occur independently and concurrently, and involve such activities as absorption into the blood, elimination from the blood, distribution between the blood and tissue, inactivation in tissues, and finally, elimination from the blood. Drug handling by the body can be characterized by the rate for each step or, more often, the rate of all processes. Classification of observed kinetics for these rate processes includes first-order, zero-order, and capacity-limited …

A Submission For The Award Of An Associate Diploma In Health Education, Claremont Teachers College

Research outputs pre 2011

Health education is a process which effects changes in the health practices of people and in the knowledge and attitudes related to such changes. Education is an internal process for the individual concerned. He educates himself, even though his education is assisted by such means as contacts with health workers, appeals directed to him, information made available, clarification of issues, alternatives, and consequences as a basis for a rational choice. Education thus places responsibility on the individual and is essentially different from a compliance approach. It involves motivation, communication and decision-making. Planned education must take into account the relevant knowledge …

Dairying In W.A., Department Of Agriculture And Food, Western Australia

Bulletins - 3000 - 3999

Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per hectare. Commercial dairy farming in Western Australia is confined to the south-western corner of the State, south of Perth, extending in a 50-kilometre-wide strip along the coast to 50 kilometres …

A Study Of Water-Soluble Inhibitory Compounds (Algicides) Produced By Fresh-Water Algae, Denny O. Harris, Manhar C. Parekh

KWRRI Research Reports

A complex system of growth inhibitors was observed in the green algae (Volvocaceae). Inhibitors were found in the culture filtrates of some genera which limit their own growth (autoinhibitors) while others in the family produce substances which check the growth of other genera (heteroinhibitors). These inhibitors were destroyed by autoclaving. It was decided that Pandorina morum, which produced the strongest inhibitor and Volvox tertius, the most sensitive to the inhibitor would make an excellent model system for a study of the chemical and physical properties of these naturally occurring algicides. The algicide could be removed from actively growing cultures about …

The Theoretical Distribution Of Forces In The Rigid Component Of The Buccal Arch Positioner, Dennis H. Teruya

Loma Linda University Electronic Theses, Dissertations & Projects

The distribution of an applied force to the rigid component of the Buccal Arch Positioner was determined with a theoretically formulated model. The rigid component was assumed to be a free body without the semi-rigid attachments and was evaluated at four points for the force distribution. The summation of the forces and the moments were equated to zero and were utilized to derive equations to solve for the unknown forces. The unknown forces at each point of the rigid component were solved for in terms of the given force applications.

A laterally directed force application at one of the posterior …

Cephalometrics For The Oral Surgeon In The Diagnosis Of Facial Deformities, Frederick J. Mantz

Loma Linda University Electronic Theses, Dissertations & Projects

Surgical orthodontics presents a challenge to the oral surgeon. By the nature of the oral surgeon's training and discipline he should be the one best qualified to treat the surgical aspect of the surgical orthodontic case. The establishment of a proper diagnosis and means of communication between the oral surgeon and orthodontist are essential in achieving a good final result for the surgically treated case. Fortunately, a scientific method of diagnosis is available that can provide both specialties with a common language. Computerized cephalometric analysis can provide the diagnosis and link of communication for the discussion of goals and treatment. …

A Method Of Analyzing Mandibular Movement, Richard B. Mccoy

Loma Linda University Electronic Theses, Dissertations & Projects

Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.

The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …

Selected Physiological Responses To A Back Rub, Norma (Ewing) Anderson

Loma Linda University Electronic Theses, Dissertations & Projects

The back rub, which has been an established part of evening patient care for many years, is given to promote relaxation and sleep as well as to promote skin care. Yet its place in modern nursing seems questionable. Today's nurse is less willing to practice using empirically established procedures.

There have been few investigations showing the effect of massage to the back and no studies have shown that a brief back rub, as given by nurses, promotes relaxation. In cardiovascular nursing there is some controversy as to whether or not the back rub causes stimulation to the cardiovascular system that …

The Nursing Process And Its Relationship To The Quality Of Nursing Care, Arlene H. Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine the effect of the systematic use of the nursing process on the quality of nursing care. Quality nursing care was defined as being achieved when the patient's nursing care needs are identified and plans made to assist the patient with these needs.

It was hypothesized that the quality of nursing care would be improved by the participation of the team leaders in a series of classes on the nursing process. This improvement in quality nursing care would be evidenced by a higher correlation between the patient's needs perceived by the nurse and …

Leadership Techniques In Groups With Chronic Schizophrenics, Judith L. Jensen, Leona W. Mcgrew

Loma Linda University Electronic Theses, Dissertations & Projects

The study was designed to assess the level of anxiety experienced by chronic schizophrenic patients when two different methods of leadership were used in group therapy. A search of literature revealed suggestions for modification of leadership approach due to the tenuous anxiety tolerance of chronic schizophrenics but no studies were found directly related to the amount of anxiety resulting from different leadership approaches.

A structured group in which the leader maintained a directive role was compared with a nonstructured group in which the leader maintained a nondirective role in the group process. The randomized sample included five male and five …

Kinesiology Of Knee Flexion Deformity Using Electromyography, Paul J. Roby

Loma Linda University Electronic Theses, Dissertations & Projects

A kinesiological electromyographic study was completed to determine the relative changes in muscle activity as a person walks and stands with different degrees of knee flexion deformity. The ultimate aim was to establish criteria for appropriate preventive and corrective measures relating to knee flexion deformity.

Six different muscles were implanted with wire electrodes. The subjects performed a series of walking and standing experiments with the knee flexed at selected angles by a locking leg brace to simulate knee flexion deformity. The electromyographic action potentials were monitored by analog tapes, oscilloscopes and closed circuit television. The analog tapes were displayed on …

The purpose of this study was to see if normal speakers and misarticulators differentially predict the frequency of occurrence of 80 words containing one or more of the five most frequently misarticulated speech sounds. The 80 words were selected from a study by Ausherman and Black. The subjects were 20 college-age individuals, ten with normal articulation and ten with articulation disorders. There were five males and females in each group.

All subjects predicted the frequency of occurrence of 80 words on the basis of an eight-point scale. Error scores were computed, used as a criterion measure, and statistically analyzed and …

Compatibility And Stability Of 8% Amino Acids Solution In Combination With Electrolytes, Vitamins And Antibiotics, David Harold Schuetz

University of the Pacific Theses and Dissertations

For centuries, researchers have attempted to devise the ideal parenteral nutritional product readily amenable to physiological requirements. Hyperalimentation, intravenous alimentation, parenteral alimentation, parenteral feeding, and total parenteral nutrition are synonyms which refer to a method of complete intravenous nutrition reserved for patients demonstrating negative nitrogen balance.

The nutrient solution appeared to accommodate levels of potassium phosphate, calcium gluconate, and magnesium sulfate well in excess of “usual” therapeutic concentrations. Similarly, commonly employed vitamin supplements and insulin were examined in combination with the hyperalimentation solution and failed to demonstrate signs of physical incompatibility. However, instrumental analysis, i.e., U.V. spectroscopy and thin-layer chromatography, …
