Paper Substrates For Electronic Printing, Laura K. Wood

Masters Theses

Printed Radio Frequency Identification (RFID) labels utilize conductive inks to provide the means for wireless flow of electronic signals. An RFID label is an identification label with an integrated circuit and antenna that transmits data via radio waves to a reader, which sends the data to a computer for processing. RFID labels allow manufacturers and retailers to accurately track their inventory more efficiently than previously possible with bar codes. However, etched metal RFID labels are too expensive for widespread implementation. The key to reducing the cost of RFID technology is replacing etched metal tags with tags printed with conducting ink. …

Habitat-Specific Diet Of The Mottled Sculpin And Its Impact On Benthic Invertebrate Community Structure, Brendan M. Earl

Masters Theses

The relationships between predators and their prey are important and influential components in the structure of ecological communities. These interactions not only impact the species involved, but can also have a wide range of direct and indirect effects that resonate throughout the community. In Michigan trout streams, one of the main predators of benthic invertebrates is the mottled sculpin (Cottus bairdi) whose diet and selective predation may influence benthic invertebrate community structure. Using gastric lavage, the stomach contents of sculpins from both erosional and depositional habitats were collected and analyzed to determine the main prey types, prey preference, …

The Influence Of Landing Technique Versus Technique And Strength Training On Valgus Knee Deformity In Females, Kirsten R. Holmes

Masters Theses

The purpose of this study was to evaluate the effectiveness of landing technique training versus landing technique and plyometric/strength training program on knee valgus during landing in females. Subjects participated in a 6-week training program. A 2 X 3 repeated measures ANOVA with two within subjects’ factors Test and Group was used to test for differences in the knee valgus angle in the landing condition and the five jump condition. A 2 x 2 repeated measures ANOVA with two within subjects’ factors, was used to test for difference in knee extension strength and knee flexion strength. Pre-test knee-valgus 4.76 ± …

Use Of Borate In Semi-Chemical Pulping, Promodh K. Veguru

Masters Theses

The original Neutral Sulfite Semi-Chemical (NSSC) pulping process used sodium sulfite as the principle cooking chemical and had the disadvantage of sulfur emission problems. Considerable research was conducted to investigate the use of other chemicals including sodium hydroxide, but was not completely satisfactory. Several mills adapted a sodium carbonate based process but experienced slower pulping and reduced physical properties. The objective of this research is to study the use of borate as a pulping chemical in sodium carbonate semi-chemical pulping. The experimental plan included digester cooks; controls with pure sodium carbonate, and the other with partially borate autocausticized sodium carbonate. …

Computer Integrated Print Production And Jdf, Deepak-Kumar Mohan-Kumar

Masters Theses

In the graphic arts industry, the need for the unification of mechanized and automated systems has seen a great increase in the last few years. This very need has led to various specification formats like, Adobe's PJTF and CIP3's PPF and the latest one of them all, CIP4's JDF. Earlier specification formats that had inherent limitations with proprietary architecture have paved the way to JDF. JDF is an open, extensible, XML based job ticket format that has been a proposed standard to achieve end-to-end job ticket specifications along with message interchange protocol and message description standard.

This thesis research has …

3d Simulation Of Layer Mixing In A Three-Layer Stratified Headbox, Jatetana Kunsriluksakul

Masters Theses

In this research, the commercially available software called FLUENT is used to simulate and visualize behaviors of flow in a three-layer stratified headbox of a paper machine. A two-phase model, "volume of fluid", is employed to simulate turbulences in a free jet. The information obtained from the simulations, in terms of velocity profiles, Reynolds stress, turbulent kinetic energy, and macro scale of turbulence, are used to assess and characterize the effect of free jet length, vane length, vane thickness, nozzle angle, and slice opening on fiber layer mixing. Importantly, the simulation results demonstrated that the macro scale of turbulence in …

Bufadienolides In The Chemical Defenses Of The Toads, Bufo Americanus And Bufo Fowleri, Catherine E. Merovich

Dissertations

Resource equalization represents the historical and theoretical basis for American school finance and its ideals continue to dominate discussion and practice. During the last decade and a half, the national aspiration for equitable distribution of school finance resources has started a transformation into a derivative notion of adequacy. This equity policy derivative embraces the idea of sufficiency, which in turn implies a standard. The concept of educational adequacy has grown to mean the achievement of high absolute standards. Equity (equalization) theorists measure resource level on a relative basis; each student relative to all others. Adequacy adherents measure student achievement against …

The Effects Of Various Types And Percentages Of Fillers With The Mechanical Properties Of Latex Saturated Paper, Jeffrey Alan Kuehn

Masters Theses

This study examined how the percentage of mineral fillers and their various types, when added to the base paper, affects the mechanical characteristics of latex impregnated paper.

A series of model handsheets were produced and subjected to physical property tests. The basis weight of these handsheets was held constant, as various types and percentages of filler were added. This base paper was then impregnated with a known acrylic emulsion. All variables with the impregnation process were held constant during the impregnation process. Physical properties were tested on the handsheets before and after impregnation. All physical tests on the handsheet samples …

The Glucose And Insulin Responsiveness Of The Rat Glucose-6-Phosphate Dehydrogenase Promoter, Daryl Arkwright-Keeler

Dissertations

The regulation of expression of some enzymes involved in glucose homeostasis and fat metabolism requires both insulin and glucose to elicit an effect, while the regulation of others requires only one. Glucose-6-phosphate dehydrogenase (G6PDH), an important enzyme involved in glucose homeostasis, has been shown to be transcriptionally regulated by carbohydrate feeding in rat liver, a diet regime that increases the levels of both glucose and insulin. Our lab had previously shown that insulin induces expression of G6PDH, thus we wanted to determine if glucose also induced G6PDH expression and if so, are the glucose and insulin responses mediated through identical …

Changes In Glial Cell Line Derived Neurotrophic Factor And Nerve Growth Factor Expression With Development, Age, Exercise And Hypertension, Bertha C. Rebimbas-Cohen

Dissertations

Neurotrophic factors are important for neuronal growth, survival, and maintenance of cell phenotype. Glial cell line-derived neurotrophic factor (GDNF) affects sensory, autonomic and somatic motor neurons and nerve growth factor (NGF) affects sensory and sympathetic neurons. NGF and GDNF are produced by cardiac muscle and have potent effects on sensory and autonomic neuronal innervation of blood vessels. Neural innervation plays a key role in blood vessel function. Since neural innervation of blood vessels may be regulated by growth factors, we wanted to determine what changes would occur to NGF and GDNF levels with maturity, exercise and hypertension.

Changes in GDNF …
