An Evaluation Of Tin Can Recycling In Kalamazoo, Michigan, Rose Ann Husted

Masters Theses

An Overview of Tin Can Recycling

Recycling Rationale

The economic system of the United States is based on taking natural resources, converting them into consumer products by industrial processes, and selling these products to consumers. It is assumed that consumers will use up all of these products. But this is not the case. The consumer uses only parts of these goods and discards the unwanted remains.

Dimensionality And Internal Composition Of The Twenty-Two Item Mental Health Inventory, John William Fox

Masters Theses

Chapter I

Introduction

Social scientists have long been concerned with the relationships between mental disorder and various sociocultural factors, such as, social economic status, ethnic background, sex, age, and marital status. Until quite recently, the majority of studies that have investigated these relationships have defined cases of mental disorder solely in terms of whether or not an individual was in psychiatric treatment (see Faris and Dunham, 1939; Rose and Stub, 1955; Hollingshead and Redlich, 1958).

The utilization of psychiatric treatment as the only criterion of mental disorder, however, has been criticized by a number of researchers. Felix and Bowers (1948), …

The Mental Patient As Machiavellian: An Exploratory Study, Louise B. Leader

Masters Theses

A basic question in the study of mental illness has been whether mental patients were victims of society or manipulators of their own careers. Four hypotheses were developed to investigate the manipulative aspect of this question. Patients were selected from three different mental institutions: a state hospital, a Veteran's Administration Hospital, and a private church-related hospital. The patients' records and a group-administered battery of test instruments provided the data used to test the hypotheses. Only one of the hypotheses was supported and the basic question remained unanswered. Lack of support for the remaining three hypotheses was not seen as conclusive …

Characterization Of Streptozotocin Induced Small Colony Phenotypes In Bacteria, David M. Zimmer

Masters Theses

Streptozocin-induced small colony variants of E. coli were characterized and found to have a genetic basis. Both E. coli and S. typhimurium were susceptible to the mutation causing small colonies. Small colony cell lines exhibited a greatly increased generation time and were shown to be non-motile, electron microscopy revealing a complete loss of flagella. The small colony phenotype was revertible by streptozotocin and nitrosoguanidine. The locus responsible for small colony phenotype in one strain of E. coli was found to map within a 19 minute segment of the chromosome between HfrH and HfrC.

An Exploration Of Numerous Customer Characteristics Associated With Impulse Purchasing Behavior, Ira J. Jager

Masters Theses

Introduction

The term "impulse buying behavior" evokes different connotations to different researchers. It is for this reason that it is difficult to formulate a universal definition for all research in the field. Engel, Kollat, and Blackwell (1968) list some of the definitions given to impulse purchasing by those who have done research in this field:

(1) "An impulse purchase is an unplanned spur of the moment decision to purchase a product."

(2) "An impulse purchase is a logical and efficient way of making purchase decisions since by waiting until one is in the store to finalize purchase intentions, a more …

Attitude Scaling As A Public Involvement Tool In The Lower Mississippi River Region Comprehensive Study, William A. Lee

Masters Theses

"The planner is under considerable pressure to involve the public in water resource planning. The public, however, often lacks sufficient knowledge to offer useful comments or suggestions. The use of a Likert Type Attitude Scale in the public involvement effort of the Lower Mississippi Region Comprehensive Study demonstrates the usefulness of attitude scaling techniques in obtaining public input to the planning process. The measurement of an individual's attitude, or his thoughts, feelings and disposition to act toward some aspect of his environment with some degree of consistency, gives an indication of the goals and objectives toward which a plan acceptable …

Distribution Of Trace Elements In Host Rock Limestone In The Tri-State Zinc-Lead District, Dinesh Jashbhai Patel

Masters Theses

"The trace metal contents of limestone in the Tri-State zinc-lead district were determined within a single horizon, the M bed. Ninety-six specimens, collected for a previous study of their petrographic character, were analyzed for zinc, lead, and copper using atomic absorption spectrophotometric techniques.

The unaltered M bed limestone at a distance from ore bodies was found to contain only 12-28 ppm zinc, 40-SO ppm lead and 12 ppm or less copper. Those limestone specimens which were found b earlier petrographic study to be altered principally to sparry calcite commonly contain anomalous amounts of zinc and lead. Some also have slightly …

Characterization Of A Mexican Halloysitic Clay And Behavior In Dry Pressing, Jesus L. Derat

Masters Theses

"A Mexican clay, intended to be used as refractory raw material, was identified. Problems encountered in the characterization of halloysitic clays are discussed and emphasis is made on the use of the electron microscope (scanning or transmission type) as a definite evidence of the existence of halloysite due to its unique morphology within the kaolinite group of clay minerals.

Beneficiation of this particular clay was carried out on a small scale hydrocyclone equipment and the results are discussed.

In an attempt to increase the green density in dry pressing of this halloysitic clay, mixtures with grog were prepared using different …

Analysis Of Interferometric Holography In Temperature Measurement, Allan James Reifel

Masters Theses

"An experimental investigation was conducted to evaluate the accuracy and sensitivity of a laser holographic interferometer. Interference fringe patterns of a free convection boundary layer on the surface of a vertical test plate were produced. The plate was heated and designed to produce a linear temperature distribution along its surface.

A thermocouple probe was used to map the temperatures in the boundary layer and these values were compared to temperatures obtained from fringe patterns. Data photographs of the holograms were used in the analysis. The number of fringes obtained were compared to predictions of the Gladstone-Dale Law.

High quality fringe …

Release Of Pollutants From Aquatic Sediments, Lloyd Aldon Hinkle Jr.

Masters Theses

"This study was undertaken to investigate factors governing the release of pollutants from sediments and subsequent effects on water quality. Studies were carried out to: 1) determine the characteristics of selected sediments; 2) determine the level of release of pollutants under batch and fill and draw conditions; 3) determine the effect of temperature and pH on release mechanisms; 4) determine the importance of microbial (uninhibited) release and physio-chemical (inhibited) release processes.

The sediment utilized was from the Missouri River at Jefferson City, Missouri, and the Burgher Branch near Rolla, Missouri. Five environmental conditions to evaluate the effects of pH and …

The Linear New City -- A Pattern For New Cities Based On Efficiency Of Transportation, Public Services, And Land Use, Elbridge Wesley Bartley Iii

Masters Theses

"The linear new city is defined as a city consisting of some arrangement of relatively narrow, high-density strips, served by various mass transportation systems. Such a new city would be ideally suited to the implementation of the latest technology. The concentration of development along the transportation route would allow certain economies in the supply of utilities and services, as well as insuring that open space would be readily available around and throughout the city. The provisions for transportation, housing, and governmental control should combine to produce a better quality of life for the inhabitants of the linear new city"--Abstract, page …

Calculation Of Gamma-Ray Albedo Using The Monte Carlo Method, Ezatholah Aslani-Amoli

Masters Theses

"Gamma-ray number, energy and dose albedo are calculated with the Monte Carlo technique. A plane monoenergetic beam was considered at normal incidence upon single material shields at initial gamma energy up to 10 MeV. Aluminum, iron and lead are used as shield material. The contribution of secondary photons which are produced as a result of various photon interactions in the shield are taken into account. These secondary photons are annihilation gammas, X rays and bremsstrahlung gammas. In certain cases, they constitute a considerable fraction of the reflected radiation.

Annihilation gammas predominate in the reflected radiation for all energies above 1.02 …

Driver-Vehicle-Roadway Interaction Model, Mark E. Jaeger

Masters Theses

"A non-trivial simulation model has been developed which combines driver and vehicle dynamics with the roadway into one system. The model was successfully simulated on a portion of an existing roadway with the dynamic response and performance of the simulator being subjectively realistic. By implementing the idea of the interaction of variables, a much more detailed and representative response is obtained as compared to previous models based solely upon a single-factor-effect approach. By analyzing a simulated vehicle's velocity and trajectory, it is felt that an increase in driver "look ahead" distance or a decrease in vehicle velocity tends to improve …

The Effects Of Acute Stress On Adrenal Ascorbic Acid Levels, Robert Joseph Collier

Masters Theses

The diurnal rhythm of adrenal ascorbic acid (DAR) displays an inverse relationship to the diurnal rhythm of circulating levels of plasma corticosteroids. Alloxan monohydrate, 175 mg/kg body weight was given subcutaneously to albino rats to determine the effect of the diabetic state on the DAR. A total of 200 female albino rats were divided into two study groups. Study Group I was composed of 150 animals divided into populations of 15, each including 3 controls. Study Group II was composed of populations of 5, each group containing all controls or all alloxinated rats. The populations of 15 were sacrificed at …

A Highway Rest Area Design Based On A Use Study In Outstate Missouri, Dimitris Peter Perandakos

Masters Theses

"The limited number of rest areas in the State of Missouri does create a major problem for the motorist travelling in this state.

The author became more aware of this problem from personal experience and decided to investigate it. For that he interviewed over one thousand motorists on the only rest area that is located on 1-44, near the city of Stanton. He also took traffic counts to determine the average daily traffic volumes of Highway 1-44 and of the rest area stated above.

The data collected from the above steps was used for the design of a new rest …
