Impact Of A Proposed Reservoir On Local Land Values, Philip Drucker, Charles R. Smith, Allen C. Turner

KWRRI Research Reports

This project was designed to study the impact of private preconstruction land acquisition in a Central Kentucky area in which a flood-control dam and reservoir impoundment is planned. The research design was built around use of anthropological concepts and research techniques. By these means it was possible to analyze the perceived values of land to traditionalist residents, among which social and economic security concepts are paramount. Recent land purchases, locally believed to have been made chiefly by "outsiders," (urbanites from nearby Louisville), at prices out of line in terms of local agricultural worth, has been extremely unsettling contributing to the …

Surface Water Turbidity In The Entrance To Chesapeake Bay, Virginia, James R. Melchor

OES Theses and Dissertations

Seasonal and spatial variations in the surface water turbidity across the entrance to Chesapeake Bay, Virginia, have been monitored with an optical transmissometer for one year. The data indicate a suspended-sediment gradient across the entrance with higher turbidity on the south side. This condition suggests that the flooding and ebbing tidal currents are influenced by Coriolis force. Clearer ocean water is introduced into the bay on the north side; whereas highly turbid water from the major drainage systems exits on the south side. A salinity gradient with18 0/00 on the south side of the bay and approximately 32 0/00 on …

Defense Contracting Policy: An Interface Mechanism With The Defense Industry, George P. Neyman Iii

Marine Affairs Theses and Major Papers

A broad overview of the contractual relationship between the military and the defense industry with emphasis on contracting trends and the impact of these trends on the nature of the defense industry, shipbuilding in particular. A brief historical survey of government contracting from the American Revolution to the present time is designed to review the principal legislative actions developed to control the procurement process. The advantages and disadvantages of the important contract types are discussed. Defense contracting policy is found to be shifting from cost reimbursement contract to the incentive contract. The trend to contract incentives is found to be …

Patients' Reactions To Witnessing Cardio-Pulmonary Resuscitation, Lynn Andree Finch

Loma Linda University Electronic Theses, Dissertations & Projects

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 …

Some Problems In Combinatorial Number Theory., Frank Ernest Higgins

Mathematics & Statistics ETDs

In this paper we consider three unrelated problems in combinational number theory. The first of these pertains to minimal residual polynomials, the second to certain group factorizations and the third to the addition of positive integers in their Zeckendorf representations.

In section II We show that for any given positive integer m there exists a unique integer monic polynomial P of least degree and whose coefficients satisfy certain inequalities with the property that m divides P(x) for every integer x. This polynomial is called the minimal residual polynomial modulo m. We then show that this polynomial assumes various forms which …

Naval And Merchant Fleet Coordination: A New Maritime Strategy, W. Gibson Carter

Marine Affairs Theses and Major Papers

The military sealift requirements of the Department of Defense and the cooperation of the Merchant Marine in times of crises, national emergencies and wars are well known. The current trend toward increasing international trade; problems of inadequate U.S. flag commercial shipping fleet and further reductions in the size of the active and reserve naval fleets, require that some cooperative effort be considered in a normal peacetime environment as well as in a crisis role. The majority of the ships of the U.S. Navy and Merchant Marine are well over twenty years old and are inefficient and uneconomical to operate. Positive …

Potential Of Pompano Mariculture In Florida, James Anthony Elias

Marine Affairs Theses and Major Papers

Pompano mariculture is not an attempt to bridge the protein gap, but it has been initiated to provide a constant source of this highly desired marine fish. The current market for pompano is small, however, this has been attributed basically to its supply. It appears from the literature that T. carolinus has the most dominant market position since it has an excellent flavor and sports fishermen prefer it due to its fighting ability when hooked on light tackle. It appears from the published history of attempts to raise pompano, by Berry and Iversen, that one of the major problems in …

An Examination Of The Inorganic Nitrogen Status Of A Soil Of The Alaskan Coastal Tundra Plain, Norton R. Munn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This experiment was designed to measure in situ concentrations of NH₄⁺ and NO₃^--N in a soil of the arctic coastal tundra plain, to determine if nitrification was taking place in this soil and to determine if the vascular plants growing in this soil could assimilate NH₄⁺-N.

The extractable NH₄⁺-N concentration was approximately 40 μg/g in the 0₁ horizon and 10 μg/g in the 0₂ horizon. The NO₃^--N concentration was approximately 5 μg/g in the 0¹ horizon and 4 μg/g in the 0_{2 …}

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 …

Population Biology Of The Black-Tailed Jackrabbit (Lepus Californicus) In Northern Utah, L. Charles Stoddart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population biology of the black-tailed jackrabbit population on a 250-square-mile area in Curlew Valley, northern Utah, was studied from 1962-70. During this period the fall population density index increased from 40.0 in 1962, to 60.6 in 1963, decreased progressively to a low of 21.2 in 1967, then increased the following 3 years to a high of 185.0 in 1970.

Breeding was synchronous with four conception periods each year; in some years a fifth conception period was evident. The first conception period occurred about the last half of January; other periods followed at 40-day intervals indicating a 40-day gestation period and …

Tertiary Igneous Rocks Of Northeastern Cache Valley, Idaho, Parry D. Willard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The tuffs and limestones of the Tertiary Salt Lake Formation in northeastern Cache Valley, Franklin County, Idaho, are intruded by basic and intermediate igneous dikes and sills. The Tertiary intrusives are exposed in an area 10 miles long and 2 miles wide between Bear River and Maple Creek in the foothills of the Bear River Range east of Preston, Idaho. They trend north-northwest. The intrusives are mostly diabase but include a small body of syenodiorite and several small andesite dikes. The intrusives seem to be emplaced along early Basin and Range faults. They are limited to the Cache Valley Member …

Stratigraphy And Environmental Analysis Of The Swan Peak Formation And Eureka Quartzite, Northern Utah, George Gregory Francis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Swan Peak Formation in north-central Utah thickens westward, from zero feet near Logan to 687 feet in the Promontory Range. The unit is subdivided into three distinct members: 1) A lower member of interbedded shales, limestones, and quartzites; 2) A middle member of interbedded shales and brown quartzites; and 3) An upper member of white quartzites. The Swan Peak thins southward toward the east-west-trending Tooele Arch in the area of study; this thinning probably reflects both lesser deposition and greater subsequent erosion there than elsewhere. The lower member in northern Utah probably was deposited in shallow-shelf and/or traditional shoreface-shelf …

Evaluation Of The Filter Paper Method For Estimating Soil Water Potential, Samir Al-Khafaf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The filter paper method for measuring soil water potential was evaluated. The method was calibrated using salt solutions (-1.4 bars to -22.4 bars), sample chamber psychrometer (-1 to -50 bars), pressure plate (-0.1 to -15 bars) and soil column at equilibrium (0 to -0.2 bars). It was found that the absolute temperature had little effect on the predicted soil water potential, but a temperature variation had a large effect. It was found that the temperature fluctuation must be small. The predicted water potential was influenced by the type of contact of the soil with the filter paper. It is suggested …

Petrology Of The Ordovician Swan Peak Formation, Southeastern Idaho And North-Central Utah, Warren J. Schulingkamp Ii

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Swan Peak Formation in southeastern Idaho and north-central Utah is a sedimentary unit consisting of orthoquartzite, sandstone, siltite, shale, and limestone. The formation is divisible into three members, and the lower two members each are divisible into two informal lithologic subunits.

The lower member consists of a lower subunit of gray, calcareous sandy siltite composed of subangular to subrounded quartz grains cemented by quartz overgrowths, calcite, or iron oxide, and an upper subunit of black shale with minor interbedded silty quartzose sandstone and biomicrite (limestone).

The middle member consists of a lower subunit of interbedded pale green shale and …

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 …

Effect Of Early Growth Cultivation On Beans And Sweet Corn, Raymond L. Cartee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations involving four cultivation treatments were conducted at the Utah State University Greenville Experimental Farm to determine the effect of these treatments on yields of beans and sweet corn. The effects of the different treatments on soil water content, soil temperature, and weed control in beans and corn were investigated. The effect of cultivation on the degree of root rot infection and the effect of different planting dates were also investigated in the bean study.

The pre-emergence treatment (ridged just before the plants emerge) produced a 48 percent greater bean yield and a 40 percent greater corn yield than the …

Enzymatic Synthesis Of Oligoribonucleotides Of Defined Base Sequence, Mark J. Rowe

Theses and Dissertations

The synthetic reaction of ribonuclease T_1 has been studied as to its potential for the synthesis of oligoribonucleotides of defined base sequence. Conditions have been determined for maximum synthesis with respect to percentage incorporation of both guanosine 2',3'-cyclic phosphate (donor), and cytidine (acceptor). With regard to maximum acceptor incorporation, a donor blocked at the 5'-hydroxyl has been used to drive the reaction. It has also been shown that acceptor incorporation decreases as the chain-length increases up to the hexanucleotide. Synthesis of a 3'-blocked substrate for polynucleotide phosphorylase for use in chain termination studies was attempted using adenylate kinase. In this …

Schottky Defects In Alkali Halides, Paul D. Schulze, John R. Hardy

John R. Hardy Papers

The method of lattice statics and the deformation-dipole model have been applied to Schottky defects in ionic crystals in approximations higher than zero order. For an isolated vacancy, all host-lattice-ion potential energy functions for short-ranged repulsive and Coulomb-defect forces were expanded to terms quadratic in the displacements and dipole moments, and the resulting forces were allowed to act on the first and/or second neighbors to the vacancy. The zero-order Coulomb force was allowed to act on the remainder of the host-lattice ions past first and/or second neighbors. The vacancy and Schottky-pair-formation energies in the 12 Na, K, Rb halides have …

Underwater Search And Rescue For Non-Military Submersibles, Peter A. Joseph

Marine Affairs Theses and Major Papers

A system of underwater search and rescue for non-military submersibles utilizing a helicopter delivered rescue submersible is proposed. In the last 10 years there has been a substantial increase in manned underwater endeavors. This expansion is expected to continue with increasingly greater emphasis in the recreational field. The necessity to overcome the relatively short iife support of the small recreation submersible dictates a rapid response. This system should be capable of providing the lift necessary to rescue the entrapped personnel by bringing the submersible to the surface. At the present time the Coast Guard must rely on other submersible operators …

Generalized Finite-Geometry Codes, Carlos R.P. Hartmann, Luther D. Rudolph

Electrical Engineering and Computer Science - Technical Reports

A technique is presented for constructing cyclic codes that retain many of the combinatorial properties of finite-geometry codes, but are often superior to geometry codes. It is shown that L-step orthogonalization is applicable to certain subclasses of these codes.

The Influence Of The Summer Thermocline On Estuarine Classification In The Chesapeake Bay Entrance, William G. Weiss Jr.

OES Theses and Dissertations

The temperature, salinity, and sigma-t of 397 oceanographic stations taken in the entrance to Chesapeake Bay were plotted using a simple interpolation formula by the lBM 1130 computer. Each station was catalogued by position, tidal stage, season, and estuarine classification. Results indicated increased stratification during the ebb phase of all entrance stations regardless of season. Partially mixed conditions predominate. The influence of the summer thermocline on the stratification caused a slight increase in the summer stratification mean. However, statistical tests showed this summer increase to be insignificant at the 95% level. Detailed classification of tidal stage by estuarine type for …

A Physical Hydrographic Study Of The Lafayette River, E. Glenn White

OES Theses and Dissertations

A basic investigation of the physical ~properties, temperature, density and current velocity, in the Lafayette River is presented. Graphs of the observations indicata a difference in salinity, density and current velocity- distributions after moderate to heavy rains from the graphs during a dry period. The changes in distribution indicate a change in the classification of the estuary from a type B/C, partially mixed estuary, to a type D, sectionally homogeneous estuary. The estuary is predominantly a well-mixed or sectionally homogeneous estuary.

Changes in salinity, temperature, density and current velocity over tidal cycles are discussed as well as tidal height data. …
