A Study On The Causes Of Variations In Transmissivity And Storativity During Pump Tests At Asylum Lake, Paul Joseph Pare

Masters Theses

Over a two year period, Western Michigan University ran a number of pump tests in the Asylum Lake Area in Kalamazoo, Michigan. The transmissivities and storativities calculated from these tests differed significantly from well to well in any particular test, and from pump test to pump test. Utilizing the computer programs AQTESOLV 3.0 and Aquifer Parameter Estimator, a number of T and S values were calculated. After analysis of the results, the following conclusion was drawn. The main reason for the deviations in the T and S values arose from the mixing of the results of numerous methods (some of …

Fiber Source Characteristics And The Effects Of Recycling On Bod And Cod Effluent Levels In Corrugated Boxboard, Craig Mefford

Paper Engineering Senior Theses

The topic of waste loading for recycle paper mills is an important issue to our industry today. As of last year the EPA has proposed the cluster rule, which suggests that the BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) loading limits are being lowered encouraging use of lower effluent loading material. The main purposes of this thesis was to focus on the effects that recycling Korean Boxboard, American Boxboard, and high yield SW Kraft has on raw waste loading in a boardmill and to analyze the characteristics of these recycled materials. This will be accomplished by separating our …

The Effects Of A Surfactant On The Pulp Properties On Non-Sulfur Semichemical Pulps, Tim Schemanski

Paper Engineering Senior Theses

Semichemical pulping involves both mechanical and chemical pulping techniques. In semichemical pulping the liquor is in contact with the chips for a relatively short period of time. The faster with liquor can penetrate the chips before they see mechanical action, the better the pulp properties. The effects of adding a surfactant to the liquor was studied. It was found that the anionic ethoxylated surfactant which was added at the addition rate of 5#/ton to non-sulfur semi-chemical pulping liquor increased the lignin content of the resulting pulp and lowered the tensile strength.

The Effect Of Internally-Filled Pulp On Recycling, Anne Spruit

Paper Engineering Senior Theses

Recycling is an area of interest for much of the industry because of all the environmental concerns with the cutting down of trees, and the pulping operations to make paper. However, virgin fibers are still desired because they make stronger paper. Virgin fibers have a higher swelling capability than recycled fibers, that accounts for better bonding. Paper's physical properties also decrease rapidly as filler is substituted for fiber. Filler impairs interfiber bonding by preventing close contact with fibers. Filler is added to paper to increase opacity and brightness. However, there is a poor retention of filler in the sheet during …

Effects Of Rote Exercise, Imagery, And A Material-Based Occupation On Postural Control In Children Ages 3-9, Robin Lengel

Masters Theses

Occupational therapy is based on the concept of enhancing motor, cognitive, sensory, and psycho-social performance through the utilization of purposeful activities. Purposeful activities are doing processes directed toward a planned or hypothesized end result, and can be naturalistic, simulated, or imagery-based (Nelson & Peterson, · 1989). This study compared the effects of a material-based occupation, imagery-based occupation, and rote exercise on the quality and duration of maintaining prone extension in children aged three to nine.· The quality of maintaining the posture was analyzed using the prone extension postural test (Gregory-Flock & Yerxa, 1984). Duration of prone extension for each child …

The Effect Of Viscosity And Polymer Additives On Fluorescent Dyes In Latex Coatings, Mark P. Comensoli

Paper Engineering Senior Theses

Fluorescent Whitening Agents (FWAs) are commonly used in many areas of the pulp and paper industry. FWAs are also known as Optical Brightening Agents (OBAs) and generically as fluorescent dyes. Nearly one-third of all FWAs manufactured are used in the pulp and paper industry. FWAs work by converting ultraviolet light into blue-white light in the visible region. When FWAs are used in coatings with latex binders, the fluorescent dyes have a tendency to migrate toward the basesheet during drying. This is due to mainly to the lack of suitable carrier for the dye. Previous research has shown that the addition …

Characterization Of Effluent From Dioxirane Bleaching Sequences, Holly L. Dunnill

Paper Engineering Senior Theses

Pulp bleaching is a multi-staged process which uses different chemicals and conditions in each stage, with washing performed between these stages. With chlorine compounds being the most widely used bleaching agents, the water from bleaching and washing stages subsequently contains a high chloride content as well as chloro-organic compounds which makes them incompatible with pulping chemical recovery processes. They are, therefore, discharged as wastewater. This leads to the need for regulations regarding the effluent quality of the wastewater. The purpose of this study is to compare effluents from various dimethyl dioxirane bleaching sequences with those of commonly used industry bleaching …

An Investigation Of Teachers' Beliefs Concerning Evaluation Procedures And Criteria And Their Willingness To Assume An Active Role In The Process, Terina Walker-Harvey

Dissertations

Teacher evaluation has received less than favorable reviews over the decades. Reports comment on the unsound practices, inappropriate assessment methods, and inadequate performance criteria. As a result, teachers in some cases come to view the process as ineffective and inadequate. This study hypothesized that (a) teachers who believe in evaluation hold different beliefs regarding evaluation specifics compared to those who disbelieve, (b) teachers who believe in evaluation and view professional development as the purpose for conducting evaluation hold different views regarding evaluation specifics compared to those who disbelieve and view personnel decisions as the purpose for evaluation, and (c) those …

An Investigation Of Turbulent Taylor-Couette Flow Using Laser Doppler Velocimetry In A Refractive Index Matched Facility, Joseph C. Parker

Masters Theses

Turbulent Taylor-Couette flow between an annulus formed by two concentric cylinders with dead end walls is comprised of complex patterns of vortices. An experimental apparatus was designed to provide refractive index matching between the annulus and working fluid. Optical access was maintained through three sides of the annulus and one end wall. An aqueous solution of sodium iodide was formulated to match the refractive index of the Plexiglas annulus. Laser Doppler Velocimetry was used to measure the three components of velocity and turbulence intensity throughout a planar section in the annulus. The annulus dimensions were: ƞ= 0.672, d = 15.08 …

The Effect Of Rotor Wake/Exit Guide Vane Interaction On The Total Pressure Losses In An Airfoil Cascade, Aaron Mosebach

Masters Theses

Computational simulations have been performed to study the effects of unsteady rotor wakes on the total pressure losses and the boundary layer characteristics in a compressor cascade. In the numerical simulations, transitional and turbulent flow conditions were modeled at design and off-design inlet flow angles, and for varying rotor wake widths and wake velocity deficits.

First, simulations were performed in the absence of rotor wakes at the inlet of the EGV (Exit Guide Vane) cascade. Second, simulations were performed for different wake width and wake velocity deficit values at the inlet of the EGV cascade. The majority of the numerical …

Class And Gender In Southwestern Michigan: Interpreting Historical Landscapes, Deborah L. Rotman

Masters Theses

The gardens, houses, and barns that comprise the cultural landscape embody information about their makers. Because the built environment is not static, it actively serves to create, reproduce, and transform relations of class and gender. Members of society use space to reinforce and resist relations of power, authority, and inequality. For example, the organization of the landscape facilitates the activities and movements of some segments of society, while at the same time it constrains others. Material dimensions of form and space are differentially acknowledged by members of society because individuals occupy multiple roles simultaneously. Material responses to the social world …

Regulation Of Leukotriene C4 Biosynthesis In Calcium Ionphore A23187-Challeneged August Rat Peritoneal Leukocytes, James M. Huebner

Masters Theses

Leukotriene (LT) C₄ is a potent myotropic product of arachidonic acid 5-lipoxygenation that is thought to play a role in the pathophysiology of immediate hypersensitivity reactions and inflammation. We designed the present study to evaluate the capacity of August (AUG) rat mixed peritoneal leukocytes to generate LTC₄ when challenged with different concentrations of the Ca²⁺ ionophore A23187 and to test the hypothesis that LTC₄ biosynthesis is regulated via a protein kinase C (PKC)-dependent mechanism. The AUG rat, which has a spontaneously high number of peritoneal eosinophils that can be harvested by a simple lavage procedure, is …

Effects Of Insulin And Insulin Mimetics On Antioxidant Enzyme Levels: In Vivo And In Vitro, Shikha Varma

Masters Theses

Tissue antioxidation status is considered to be an important factor for elucidating the etiology of diabetes and its physiological complications. This study was aimed to determine the in vivo antioxidant enzyme levels in the altered antioxidant status of diabetic rat liver with the treatment of two potent insulin mimetics, vanadium and selenate. The direct effects of vanadate, selenate, and zinc (another insulin mimetic) on the antioxidant enzyme levels in primary rat hepatocytes in culture was also determined. Levels of superoxide dismutase (SOD), catalase (CAT) and gluthahione peroxidase (GPX) were determined in both model systems.

In the vivo model, insulin treatment …

The Effects Of Air Sparging On Aquifer Hydraulic Conductivity, Hans Neve

Masters Theses

Air sparging is a relatively new technology used to remove organic contaminants from aquifers. This remediation technique involves injecting into contaminated portions of water table aquifers. Theoretically air sparging will reduce aquifer hydraulic conductivity. Injected air fills some of the available sediment pores, thus restricting the flow of water to the remaining water-filled pore spaces.

The purpose of this study was to measure the reduction in hydraulic conductivity due to air sparging. This was assessed using both laboratory and field techniques. The hydraulic conductivities of several different sediments were determined in the laboratory using a large constant head permeameter modified …

Dynamic Pulse Buckling Of Columns With Viscous Damping, Murli Kadandale

Masters Theses

This is a study of dynamic pulse buckling of columns with viscous damping. The differential equations of motion were obtained using the Bemoulli-Navier hypothesis. The effects of axial and rotary inertia were included in the analysis. The Voigt-Kelvin model for a viscoelastic material is used. The Finite Difference Method was employed to solve the differential equations of motion. First columns without geometrical imperfections were studied, and a correlation between the damping modulus and the more familiar damping ratio was obtained. Then beams with initial geometrical imperfection were studied. A suitable dynamic buckling criterion was defined. It was observed that viscous …

Toward A Theory Of Gendered Reading, Larry Edward Schoenholtz

Masters Theses

Sociolinguistic studies have long acknowledged that men and women sometimes read, write, speak, and view differently. This is often recognized as a cultural phenomenon, but there are increasing reasons to suppose that biology may play a larger role in these differences than was suspected two or three decades ago. Over the last fifteen to twenty years, in particular, evidence has continued to mount in that direction from studies in neurophysiology, endocrinology, and infant behavior. In addition, sociobiological perspectives first proposed in the 1970s seem to have met with large success in being confirmed by cross-cultural studies done in the 1980s. …

Band Structure For Acoustic Waves Propagating In A Periodic Elastic Media And Impurity Modes Arising From Slab Substitutions, Abdur Rahman

Masters Theses

In this thesis I study the band structure for acoustic waves propagating in a one-dimensional elastic array which forms a periodic elastic system in which band gaps are opened in the frequency spectrum. Specifically, I study the single impurity problem in this system. An impurity is introduced in the system by replacing one of the acoustic slabs with a new slab of different acoustic medium or by changing the thickness of impurity slab. I study the very narrow (in frequency) impurity modes in the band gaps which are localized about the impurity sites. Then I study the frequency of impurity …
