The Wavelength Dependence Of Herpes Simplex Viral Inactivation & Ultraviolet Enhanced Reactivation, Richard Detsch

Masters Theses & Specialist Projects

The degrees of Ultraviolet Enhanced Reactivation (UVR) by mammalian cells of Heroes simplex virus inactivated by different wavelengths of far ultraviolet radiation were measure'. The wavelength dependence of UVR is presented for the wavelength region 238 nm to 297 nm. The shape of the UVR curve suggests that virus directed repair is less dependent on the wavelength of UV radiation than are cellular repair mechanisms. The wavelength dependence of Herpes simplex inactivation by far UV radiation is also presented. The shape of the virus inactivation curve suggests the involvement of both DNA and protein.

Fatigue Properties Of Orthodontic Wire, Kirkland B. Reuer

Loma Linda University Electronic Theses, Dissertations & Projects

Fracture of orthodontic appliances can be a problem because of the time involved to replace and repair them. It has been shown that most failures have been a result of fatigue fracture, i.e., failure resulting from cyclic loading.

The purpose of this study was to determine what effect variation of the type of orthodontic wire and heat treatment had on fatigue resistance. A device was constructed to put a cyclic load on a piece of wire until fracture. Two types of cobalt-chromium alloy wire (Blue and Green Elgiloy from Rocky Mountain Orthodontics) and three types of stain less steel wire …

The Effect Of Primary Nursing On Nurse Job Satisfaction And Patient Satisfaction With Nursing Care, Karen Garrison

Loma Linda University Electronic Theses, Dissertations & Projects

Nursing as a profession has seen the loss of large numbers of practitioners through job dissatisfaction. In addition, recent studies testing professional growth among new graduates have demonstrated negative findings. Lack of responsibility and accountability have been indicated as potential causes of these problems which confront professional nursing.

In nursing modalities such as functional, case method and team nursing the lack of autonomy in providing care is visible. The team nursing approach fragments patient care; a nurse in this system is responsible for team members rather than directly for patients. The registered nurse does not have enough personal contact in …

In Vitro Incorporation Of Molybdate Into Demolybdoproteins In Escherichia Coli, Randolph H. Scott, George T. Sperl, John A. Demoss

Faculty, Staff and Student Publications

When Escherichia coli was grown in the presence of tungstate, inactive forms of two molybdoenzymes, nitrate reductase and formate dehydrogenase, accumulated and were converted to their active forms upon incubation of cell suspensions with molybdate and chloramphenicol. The conversion to the active enzymes did not occur in cell extracts. When incubated with [(99)Mo]molybdate and chloramphenicol, the tungstate-grown cells incorporated (99)Mo into protein components which were released from membranes by procedures used to release nitrate reductase and formate dehydrogenase and which migrated with these activities on polyacrylamide gels. Although neither activity was formed during incubation of the crude extract with molybdate, …

Interplanetary Magnetic Field Sector Polarity And Neuropsychiatric Adaption: A Reanalysis, Hans W. Wendt

Journal of the Minnesota Academy of Science

Recent Russian studies reported associations between adaptation syndromes and (solar activity-related) interplanetary magnetic field (IMF) sector polarity. Certain ambiguities in the original work suggested some reanalyses, based on the graphs and data made available. Syndrome status exhibited a biphasic (semi annual) trend. It also correlated with specific geomagnetic changes during magnetic storms and possibly after sudden impulses. Moreover, lag effects and higher order interactions were noted among all parameters investigated. The restudy tends to support some of the original findings but also suggests new conclusions regarding potential relationships between geophysical/solar and psychophysiological processes.

Relationship Between Some Demographic Characteristics And Adverse Reactions Experienced By Women Undergoing A Therapeutic Abortion While Awake, Karen K. House

Loma Linda University Electronic Theses, Dissertations & Projects

With the liberalization of abortion laws by the Supreme Court in 1973, American women have been able to obtain therapeutic abortions in hospitals and out-patient clinics in ever increasing numbers. With the increased number of women seeking abortions the medical field has responded with abortion procedures that are safe and relatively quick. With the speed doctors use to perform the procedure, many women may wish to take advantage of the medically safer method of abortion under local anesthesia. However, some women are unable to withstand the psychological and physical stress associated with a therapeutic abortion while awake. It would be …

The experimental study attempted to determine whether pre-admission crisis nursing intervention had any effect on the level of anxiety of elderly people when they were transferred from an acute hospital to a nursing home.

The literature review related to trends in numbers of nursing homes and in the increase in longevity. Several articles indicated that the aged, as a group, lacked power to alter their situations. The need for patients to express their feelings and participate in their own decisions was stressed in various studies. Other theories discussed theoretical aspects and goals of crisis intervention. Several articles suggested that crisis …

The Effect Of Planned Physical Activities On Deficient Motor Skills In Head Start Preschool Children, Darlene L. Robinson

Loma Linda University Electronic Theses, Dissertations & Projects

During the past few years many physicians, nurses, psychologists, teachers, and physical educators have begun to place more emphasis upon the developmental problems of children. As an outgrowth of this, more attention has been given the child showing mild to moderate motor problems. As a result of these more subtle difficulties going unrecognized and untreated, children may suffer from learning disorders, lack of acceptance by teachers and peers, maladaptive behavior and feelings of low self-esteem (Cratty, 1970; Kiphard, -1970; and Ferinden, 1972).

The purpose of this study was to ascertain whether planned physical activities would aid in remediation and/or modification …
