A Mathmatical Model Of Primary Productivity And Limnological Patterns In Lake Mead, Lorne G. Everett

Publications (WR)

The temporal and spatial changes in chemical and biological properties of Lake Mead have been investigated, thereby indicating the sources of water pollution and the time of highest pollution potential. Planktonic organisms have been shown to indicate the presence of water problems. Macro- and micro-nutrient analyses have shown that primary productivity is not inhibited by limiting concentrations. A mathematical model has been developed, tested with one set of independent data, and shown worthy of management utility. Although the model works very well for the Lake Mead area, the physical reality of the Multiple Linear Regression equation should be tested on …

A Community Health Nursing Care Plan, Gayle Clark

Loma Linda University Electronic Theses, Dissertations & Projects

Structured nursing care plans are recognized tools in the effective utilization of the nursing process. Community health nursing services have not commonly used structured nursing care plans.

A Correlation Of The Idealized Heat Of Vaporization To Molecular Weight, Harold Earl Bennett

Master's Theses

Using the Clausius-Clapeyron equation as a base, many investigators have tried to develop variations to better describe both ideal and non-ideal systems. The literature is abundant with correlations of vapor pressure to temperature and associated correlations of latent heats of vaporization to molecular characteristics; often molecular weight or carbon number.

Current Post Development Problems, Andrew J. Conklin

Marine Affairs Theses and Major Papers

The major problems confronting United States' seaports are investigated as they relate to the 1970s time frame. The influence of the merchant marine's transition to new, large and deep drafted ships is examined as it pertains to harbor and channel depth, pier and storage requirements, waterborne traffic control and port economic impact. Present seaport facilities are barely keeping abreast with new developments in cargo transportation and handling methods. Additionally, major port development problems are magnified by the recent awarenesss of the environmental value of the coastal zone. Only a limited amount of area remains in most ports, both below the …

The purpose of this study was to describe the reactions to stress in patients witnessing a cardio-pulmonary resuscitation, in order to determine if the witnessing patients' needs are being met adequately, and to determine the effect of a specific psychological stressor on patients.

All resuscitations ("STATS") done over a two-month period at Loma Linda University Medical Center, with oriented patients in the room, were observed and recorded on an Observation Guide. A Questionnaire was also solicited from medical-surgical nursing personnel who had observed "STATS" with witnessing patients in the last three months. The Guide and the Questionnaire were developed from …

Post-Abortion Counseling And Anxiety Levels Of Unmarried Adolescents Having Therapeutic Abortions, Linda Levisen

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the effectiveness of a post-abortion counseling program. It was hypothesized that unmarried adolescents who received counseling following a therapeutic abortion would exhibit significantly fewer negative affects than those who received no counseling. The affects measured were anxiety, depression, hostility, and guilt. Twenty clients were randomly selected for this study. Prior to the abortion, the twenty clients were-tested for negative responses to the unwanted pregnancy. Ten clients received post-abortion counseling twice following the abortion and were tested at each visit for negative affective responses to the abortion. The other ten clients received no …

The Development And Constitutionality Of The 1971 Delaware Coastal Zone Act, Francis Cameron

Marine Affairs Theses and Major Papers

In June 1971, the Delaware Legislature passed the Delaware Coastal Zone Act that barred heavy manufacturing industry from locating in an area one to six miles deep along the state's 115 mile coastline. The act created a State Coastal Zone Industrial Control Board to hear appeals from decisions of the State Planner. In addition, the act prohibited the construction in the bay of marine terminals for the transshipment of liquid and solid bulk materials of any substance, (specifically aimed at offshore oil and coal transfer) from vessels to onshore facilities. The law's immediate effect was to block several hundred million …

Saltmarsh Ecology And Resource Protection, Gerard Desire Blais Jr.

Marine Affairs Theses and Major Papers

A panoramic lack of conservation education has produced a populace largely unaware of the value of marshland resources or measures for their protection. In a relentless era of ecological abuse, wetlands and salt marshes rank with endangered animal species in the quantitative loss culminating in extinction. Challenged continually by the relentless sea and exploited by unsound attempts at development, management, or even conservation, the efficiency of the marshlands is decreasing with each successive invasion. There is a demonstrated reduction in biological productivity, flood control, and water quality in areas where dredging, draining, and filling of marshes has taken place.

A Draft Proposal For The Management Of The Offshore Sand And Gravel Deposits Of The State Of Rhode Island: Guidelines And Model Regulatory Legislation, Malcoolm Johnston Grant

Marine Affairs Theses and Major Papers

The Coastal Resources Management Council is charged with broad responsibility to "develop resource management plans compatible with the needs of the people of Rhode Island, while preserving and enhancing as far as possible the natural qualities of the marine environment." The proper function of coastal management is to maximize the options open to the people of Rhode Island in the development of their coastal resources. This goal can best be realized by providing for the resolution of developmental conflicts before they materialize. Uncontrolled past development and consequent unanticipated use conflicts of many types have already seriously compromised Rhode Island's ability …

Two Emotional Factors And Weight Loss Among Females Attending A Weight Control Class, Karen Lynn Carrigg, Eileen Rae Wangerin

Loma Linda University Electronic Theses, Dissertations & Projects

A descriptive study was conducted on twenty-four females attending a weight control class to discover the effect of weight loss upon levels of self-esteem and anxiety, as an understanding of the relation of these factors to reduction and control of weight would prove helpful to community health nurses in counseling with overweight and obese persons in the community.

The entire sample was tested for self-esteem (TSCS) and A-State and A-Trait anxiety levels at the initial class of the weight control program sponsored by the Health Education Department of Loma Linda University Medical Center, and again after seven weeks of class …

Assisting Mothers To Successfully Breast Feed Their Babies, Annabelle Moore

Loma Linda University Electronic Theses, Dissertations & Projects

This experimental study tested the effect of a teaching program on success of a group of mothers desiring to breast feed their babies. It was hypothesized that mothers receiving specific instructions on the physiology of lactation and the proper sucking technique would have greater success than mothers not so instructed.

To be categorized as successful the mothers had to have an adequate supply of milk and had to express satisfaction with breast feeding. Criteria for adequacy of milk supply consisted of weight gain of the infant within accepted norms without use of supplementary formula.

Twenty breast feeding mothers who delivered …

A Clinical Comparison Of Six Orthodontic Techniques, Erik H. Madsen

Loma Linda University Electronic Theses, Dissertations & Projects

Controversy exists concerning the relative superiority of various orthodontic techniques because of the difficulties encountered in making comparative clinical studies of these techniques which are scientific and statistically meaningful. The purpose of this study was to clinically compare six different orthodontic techniques which are currently being taught, relative to a number of criteria, and to do it in a scientifically significant manner.

In order to eliminate as many of the irrelevant variables as possible, the patients were required to pass a relatively stringent screening to participate. Among other things, the patients had to have first molars in Class I relation …

Selected Factors Related To Ability To Regain Bladder Function Following Indwelling Catheterization, Jongkolnee Padmasiri

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory retrospective study was designed to evaluate selected factors, including the ability to regain bladder function related to post indwelling urethral catheterization in an acute general hospital population.

The records of 107 patients who met the study criteria became the study population. These patients had three-way urethral catheters, continuous antibacterial irrigation and closed drainage system. Twenty patients died (19 percent) before the catheter was removed. Of the 87 patients who were alive, 37 percent (32 patients) had in-adequate bladder function. Of these 32 patients, no attempt was made to remove the catheter from 15 prior to their hospital discharge. …

Effect Of Bear River Storage On Water Quality In Bear Lake, Utah-Idaho, Robert L. Nunan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since 1912 concentrations of the major anions and cations (except calcium) in Bear Lake water have shown a steady decrease which has been attributed to a dilution of Bear Lake by Bear River water, Bear Lake having been used as a reservoir for Bear River water since 1918. This study examined the changes which have occurred in Bear Lake water chemistry since 1912 and tested the validity of the dilution theory.

Simple water and salinity budgets were determined for the Bear Lake system and used to simulate the effect of Bear River storage patterns since 1918 on the concentrations of …

Commensal Rodent Control, D. R. Maddock, H. F. Schoof

Vertebrate Pest Conference Proceedings: 5th (1972)

SUMMARY: Federal Urban Rat Control Program grants were awarded to cities in different areas of the United States. Severe problems of rat infestations have been detected in many of the cities by the Environmental Health Service. Approximately 20% of 3.8 million people in the project areas were occupying homes infested with rats. Control operations are now in effect in all cities, and the living conditions of the people have been substantially improved. An increase in interest in rodent control also is evident in countries outside of the United States. The Technical Development Laboratories of the National Communicable Disease Center are …

Tolerance Shown By Rattus Rattus To An Anticoagulant Rodenticide, P. J. Deoras, G. C. Chaturvedi, N. E. Vad, D. M. Renapurkar

Vertebrate Pest Conference Proceedings: 5th (1972)

Apart from using 0.005% concentration, the recommended field dose of 0.025% of the anticoagulant is used along with an alternate food for individual rats for a varying number of days. Those that had survived were taken as tolerant, provided they showed an mg/kg intake beyond the tolerance limit, survived a six days of feeding, exhibited bait-shyness and did not exhibit hemorrhage after death. In determining the criteria for tolerance to an anticoagulant by a rat, one should take into account four composite factors. These are, six days of even 0.025% feeding, bait-shyness when alternate food is given, higher mg/kg intake …

Status And Control Of Nutria In California, Frank Schitoskey Jr., James Evans, G. Keith Lavoie

Vertebrate Pest Conference Proceedings: 5th (1972)

Although feral nutria (Myocastor coypus) have been present in California since the mid-1940's, they are quite scarce and at present are causing little or no agricultural damage. Present state regulations and pest detection activities will probably prevent them from becoming a serious economic pest. Should control ever become necessary, studies in other areas indicate that shooting, trapping, and baiting with zinc phosphide should be effective.

Muskrats In Central Europe And Their Control, Kurt Becker

Vertebrate Pest Conference Proceedings: 5th (1972)

An account of the introduction of muskrats into Europe and their spread over the countries of Europe is presented. The reasons why the animal should be controlled are discussed. Legal regulations often do not keep up with the requirements and economic and political circumstances and frequently have encouraged the spread of muskrats. The use of traps alone does not solve the problem of their control. Therefore research is looking for suitable poisons and a good practice to apply them. At present this question cannot be answered satisfactorily.
