The Uses Of Pins For Retention In Restorative Dentistry : An Independent Learning Program, Ali M. Asad

Loma Linda University Electronic Theses, Dissertations & Projects

Although pins have been used since the 1800's for retention of dental restorations, their widespread use had been limited because supporting techniques such as impression, die materials, better handpieces and drills have only been perfected in the last two decades.

The pin technique allows for greater retention of restorative materials which otherwise might require considerable reduction of sound tooth substance; this is particularly paramount when insufficient coronal tooth structure is present. Also, the placing of pins in divergent directions gives excellent retention. Pin-retained castings reduce the need for deep cavity preparation in some cases.

Pins are useful in stabilizing hypermobile …

Tudor Conciliar Theorists, Daniel E. Mitchel

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis analyzes a variety of sources such as printed books, diplomatic correspondence, letters, and notes, from which a description of Tudor ideas in relation to proposals to hold a general council can be derived. This Tudor Conciliar Theory has a definite beginning.

Henry VIII developed a flexible foreign policy to deal with continental suggestions to hold a general council of the church. The position which he took was that the English nation was not opposed to such a gathering, but on every occasion, matters of detail were used to block English participation. While these procedural details kept Henry from …

Growth Lines In Chione Fluctifraga And Prothaca Staminea (Bivalvia): Precision Of Counting And Comparisons Of Size, Age, Intertidal Location And Taxa, David M. Crabtree

Loma Linda University Electronic Theses, Dissertations & Projects

Because formation of growth lines in the shells of bivalve molluscs is affected by environmental parameters, the growth lines should contain much information about the environments in which the animals live. However, the use of growth lines in ecology· and paleontology is limited by ambiguity in their identification.

Chione fluctifraga and Protothaca staminea were collected, marked, and replanted. C. fluctifraga were grown at three intertidal levels over a vertical range of one meter. In addition, P. staminea were grown at the middle level. All specimens were re-collected after 47 days. Acetate peels of shell cross sections were use for growth …

The Development And History Of The Seventh-Day Adventist Church In China Since The Communist Take-Over, Lien-Chieh Tsao

Loma Linda University Electronic Theses, Dissertations & Projects

In evaluating the status of Christian religions in China today, this paper draws largely on unpublished sources. Since China is a "closed" country, accurate reports are somewhat limited and quite scarce. As a result, this thesis depends on unpublished memoirs of friends who were in China at the time and on correspondence and conversations with people who have made recent visits to the mainland. From these sources the paper attempts to describe the current condition of Christianity in China, trace some of the causative factors, and evaluate the potential for future mission work.

To provide a background and help explain …

The Requirement For Viable Platelets In The Coagulation Of Heparinized Blood, Karen L. Hay

Loma Linda University Electronic Theses, Dissertations & Projects

Activated coagulation times (ACT's) of heparinized blood or plasma samples containing normal platelets were compared with ACT’s of heparinized samples containing non-viable or abnormally functional platelets. The non-viable platelets were prepared by freeze/thawing, and the abnormally functional platelets resulted from the addition of adenosine or adenosine 5'-diphosphate (ADP).

The ACT’s of the heparinized samples containing treated platelets were considerably longer than the ACT’s performed on samples with untreated platelets. Treated platelets had no effect on unheparinized samples, however. This would indicate that, although platelet factor 3 (PF3) is sufficient to promote clotting of unheparinized blood, viable platelets, in addition, are …

The Effect Of Masking On The Acoustic Reflex Threshold, Nancy E. Aldrich

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigated the effect of masking noise on the threshold for stapedial reflex. It has been shown that masking which shifts the hearing threshold causes a loudness function typical of recruitment. It was hypothesized that the stapedial reflex threshold remains the same in a masked situation as in the unmasked situation . It was suggested that this demonstrates recruitment in that the presence of noise reduces the range between hearing thresholds and stapedial reflex thresholds.

Ten subjects, with no known hearing loss or pathology involving the ear or reflex arc were used in this study. A 1000 Hz tone …

Sexual Parameters In Doctor-Patient Relationship, Judith Adams Perry

Loma Linda University Electronic Theses, Dissertations & Projects

A survey to determine the attitudes and practices of physicians regarding touching (erotically and nonerotically) their patients was conducted with 164 female physicians. The results were compared with a previous study (from the University of California, Los Angeles) of male physicians. As compared with the UCLA sample of male physicians, more female physicians believe in and engage in nonerotic touching; but fewer female physicians believe in and engage in erotic touching. None of the female physicians reported sexual intercourse with their patients as compared with 33 or 11% of the UCLA sample of male physicians.

B And T Lymphocytes In Human Pregnancy, Ted Fong

Loma Linda University Electronic Theses, Dissertations & Projects

The success of the fetus as a transplant has been attributed to an immune depression in the mother. It has not been shown whether this purported depression was due to fewer T-lymphocytes or a dysfunction of these cells. T cells were measured by the rosette technique using neuraminidase treated sheep red blood cells (SRBC). B cells were measured using a SRBC-hemolysin-guinea pig complement indicator system. The total leucocyte count in the pregnant group was significantly higher than the control group but this was not reflected in the absolute number of lymphocytes. Compared to non-pregnant women, the pregnant group did not …

Subvocalization And Stuttering, Laverne Brent Gohl

Loma Linda University Electronic Theses, Dissertations & Projects

Twenty-six subjects, thirteen stutterers and thirteen fluent speakers, were matched by age, sex and educational background. None had any history of neurosurgery, neuropathology or debilitating injury to the head or neck.

Two GRASS silver chloride electrodes were attached to the chin and inferior surface of the lower lip of each subject. This recording site was chosen because, presumably, it would detect activity of the quadratus labii inferioris, a muscle involved in the articulation of labial phonemes, permitting a distinction between the labial and nonlabial ensembles and, therefore, speech and nonspeech oral activity. EMG recordings, measuring covert phonetic activity, were obtained …

Bench and Ricketts and were selected on the basis that each case must include three complete sets of frontal and lateral headplates, before and after treatment, and a minimum of two years out of …

Escape In Thurber : From Delight To Delirium, Carol Richardson Boyko

Loma Linda University Electronic Theses, Dissertations & Projects

James Thurber (1894-1961) is the outstanding American literary humorist of the twentieth century, whose writing spans two periods of American humor: pre- and post-World War II. Pre-war humor is characterized by a debunking of traditional values: the sanctity of women and marriage, patriotism, hero worship, and the supremacy of common sense. The hero of this era is the victim, the slightly neurotic man who does not fit into high-pressured city life. Post-war humor moves from playfulness to bitterness, from misogyny to misanthropy, from man's displacement in inhuman society to man's displacement in the world.

The theme of escape in Thurber …
