A Comparison Of Ecs And Drug Induced State-Dependent Learning, Mayse F. John

All Master's Theses

The purpose of the present experiment is twofold: (a) to determine if FS and ECS or just ECS can be used as an agent to produce "dissociated" learning in a multi-trial procedure, and (b) if shown, to determine the effectiveness of these agents relative to three different dosages of sodium pentobarbital preselected to produce no, moderate, and complete dissociation.

Comparison Of Amounts Of Verbal Response Elicited By A Speech Pathologist In The Clinic And A Mother In The Home, Joan Mathis

Dissertations and Theses

Language assessment of children is an essential task of the speech clinician and many studies have been concerned with the validity of the data gathered. Few studies, however, have investigated examiner variability as a possible source of deviation in language assessment. This study was designed to evaluate and compare the amount of verbal output which children with normal language use when examined by two different examiners when the examiners are in their most comfortable setting.

Six children, four years of age, were examined by a speech pathologist in the clinic and the mother in the home and the 12 fifteen-minute …

The Biodegradability Of Detergents And The Effects Of Biodegradable Detergents Upon Root Elongation Of Certain Plants, Nancy Lou Bishop

Masters Theses

The effects of three biodegradable detergents upon root elongation of Cucumis sativus and Avena sativa was determined. All three detergents inhibit root elongation; the degree of inhibition depends on the brand of detergent and the species tested. Contact of the detergents with a sandy-loam results in reversal of inhibition of root elongation; the degree of reversal varies with detergent and species. However, reversal after 48 hours contact with soil does not appear to be due to degradation by microorganisms. Effects of aeration and of pH on test solutions are discussed.

Vital Apical Cortical Marginal Ostectomy, Elbert W. Clark

Loma Linda University Electronic Theses, Dissertations & Projects

The dentition has been suspect as an unfavorable influence in the healing potential of the jaws. Today, many surgical procedures are based on the supposition that teeth should be avoided, endodontically treated, or removed from the sphere of tissue infliction. On the other hand, and abundant blood supply and osteogenic capability have been recognized as favorable factors in repair.

An extra oral removal of an osteoid osteoma from the body of the mandible of a thirty-year-old female resulted in vital apicoectomies of her molar teeth as well as the removal of the medullary blood supply. An uneventful course of healing …

The Effect Of Self-Directed Structure Versus Adult-Directed Structure In The Learning Of Articulation Skills In First And Second Grade Boys And Girls, Doris Elaine Haley

All Master's Theses

The comparative effectiveness of two speech correction approaches was studied in the therapeutic situation (within the program and the setting of the public school). The Van Riper adult-directed auditory stimulation method, used by many speech therapists today, was compared with a self-directed and modified Backus and Beasley approach to sound correction. The problem resolved was: Which method will be most effective in helping first and second grade children acquire adequate articulation skills?

Molecular Weight Determinations Of Some Salmonella Potsdam Bacteriophage Dna's, Winston H. Richards

Loma Linda University Electronic Theses, Dissertations & Projects

Two group A phages, P9c/2 and P4/2, were studied. Their density, sedimentation velocity, and biochemical properties were compared. Their densities were determined by density gradient centrifugation in 38.3% cesium chloride. Sedimentation velocity was used to determine their molecular weights. To accomplish this, the DNA of P9c/2 and P4/2 was labeled with tritium and T₂ DNA, labeled with ³²P, was used as a standard. The DNA of P9c/2 and P4/2 was separately mixed with T₂ DNA and centrifuged in a 0-15% sucrose gradient. The molecular weights were calculated using the formula D₂/D₁= (M_{2 …}

A Study Of Temporomandibular Joint Movement After Mandibular Alteration, Donald L. Cram

Loma Linda University Electronic Theses, Dissertations & Projects

In this study of the temporomandibular joint, two instruments were employed to aid in understanding the effect of alteration of the mandible upon temporomandibular joint functions The two instruments employed were the S, S, White Panorex Radiograph and the Denar Pantograph tracing device. The question was considered, does alteration of the mandible result in a modification of the functional path of the mandibular condyle? Should one expect normal function to return to the temporomandibular joint of a mandibular condyle fracture patient?

A group of 12 patients were studied with the Pantograph to determine a set of standard values for the …

An interview guide was used to gather the data for this exploratory study. The questions on the interview guide were designed to obtain information to compare the former exercise pattern of the patient to exercise after infarction. Adherence to the exercise prescription was also determined by the exercise reported in the interview. Fifteen male subjects who had myocardial infarction were interviewed in the hospital and after …

The Relationship Between The Lingual Surface Of The Maxillary Central Incisor And The Eminence Of The Mandibular Fossae, Robert A. Huffer

Loma Linda University Electronic Theses, Dissertations & Projects

Gnathologists have suggested that in order to prevent excessive wear on posterior teeth, alveolar bone loss due to traumatic occlusion, and temporomandibular Joint (TMJ) disturbances, the mandibular incisors should disclude the posterior teeth by moving along the lingual surfaces of the maxillary incisors as the condyles move down the articular eminence in protrusion. It is suggested that in order for this to occur, the lingual surface of the maxillary incisors should be steeper than the eminence.

A cephalometric technique was developed to accurately determine the anatomical form of the articular eminence. A regular orthodontic tracing of the head was done …

Equipment And Space Utilization In Hospital Food Service Systems, Robert E. Jacaban

Loma Linda University Electronic Theses, Dissertations & Projects

The concept of convenience food service systems has evolved as a result of technological progression in food preparation, processing, packaging and equipment to curtail input resources of space, equipment and labor. The purpose of this research was to (1) compare the allocation of space in six selected hospital food systems designed for convenience or for conventional operations with estimated needs suggested by Kotschevar and Terrell (1961a) and (2) identify types, determine units and utilization time of production and reconstitution equipment in the two systems.

Space allocations were calculated for each of the subunits within the food system. The square feet …

An In Vivo Perfusion Apparatus For Studies On Gingival Disease In The Albino Rat : Assessment By A Perfusion Of The Enzymes Collagenase And Hyaluronidase, James A. Smith

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis describes an in vivo perfusion apparatus which can continuously deliver controlled quantities of solutions to localized, contralateral intraoral areas in albino rats. Three animals were per fused on the experimental area (the mesial sulcular area of the maxillary first molar) on one side with tap water and Trypan blue. Localization of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. Solutions of .5%, 1%, and 2% hyaluronidase and collagenase were perfused on the experimental areas of nine animals. When both enzymes were used, hyaluronidase always preceded collagenase in …

An Electromyographic Comparison Of Muscle Action Potentials Of Listeners Presented Time-Compressed And Normal Speech Stimuli, Barbara S. Moon

Dissertations and Theses

Speech compression is a method of electromyographically reducing the speech signal, resulting in a decrease in the time required for presentation of a message by increasing the number of words per minute. Research in the area of speech compression has to this time been focused on determining the listener response by means of comprehension testing. While comprehension testing uncovers the individual's ability to resolve, organize, and recall a message at accelerated rates, it gives no information about the listener's psychophysical response to compression. Does the individual find listening to compression to be tension-provoking or stressful? Or can a listener accommodate …

Selective Inhibition Of Intestinal Amino Acid Transport By Three Heavy Metals, Verney Lee Sallee

Biomedical Sciences ETDs

Intestinal absorption of neutral amino acids, an active transport process, selects certain amino acids for transfer on the basis of their chemical structure. However, within the group of transported neutral amino acids, selectivity into secondary groups is not readily apparent, and only a relative variation of transport rate for each amino acid has been noted. A popular hypothesis, consistent with previously reported experimental observations, holds that intestinal transport of neutral amino acids occurs through mediation of one transport system with one effective binding site.

Donation Of Organs For Transplantation: An Investigation Of Attitudes And Behavior, Courtney Weldon Goodmonson

Dissertations and Theses

While technological advances in immunology and surgery have permitted rapid increases in the number of homotransplantations now performed, little is known about layman’s attitudes toward donation of organs. Implicit in such progress has been the medical field's assumption that enough donor organs will be forthcoming to meet the increasing demand. In order to research this area a dual emphasis on practical and theoretical issues was employed. The purpose of the present study then, was to investigate this medical assumption by sampling the attitudes and behavior of college students toward donation of organs for transplant purposes, and at the same time, …
