Comparison Of A Pin Cam And An Inverted Pin Cam Design Based On The Parameters Used For The Axial Vane Rotary Engine (Beta Version)., Phillip Howard Burnside

Graduate Theses, Dissertations, and Problem Reports (ETD)

The comparison of two design variations of the Axial Vane Rotary Engine (AVRE) was done by evaluating several parameters. These two designs are called the Pin Cam and the Inverted Pin Cam designs. The first step involved developing a technique to determine the heat loads on the components of the engines since the engine is running at a steady state loading condition. The second step used this thermal data to get a final temperature profile. The third step combined the thermal data and the combustion data to perform a structural analysis of the engine components. This illustrated both the stresses …

Faculty Stance Toward Multiculturalism And Multicultural Education: A Qualitative Study., Jane Sheridan Cardi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Studies indicate that the implementation of multiculturalism into university general education course requirements such as introductory American literature is sporadic. Furthermore, although research suggests that faculty are more frequently including multicultural literature in their courses, there is little research concerning what faculty believe about multiculturalism and multicultural education and how faculty actually teach multiculturalism in higher education. The purpose of this study is to contribute to the knowledge of why faculty do or do not implement multiculturalism into their curricula and if they do, how they implement it. This study uses phenomenological and hermeneutic research methods to explore the stances, …

There Was Something In The Water: Parallels In Paradigms In English And Physics, 1880 To 1940., Tracy Joan Demars

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study posits that a paradigm is a shared vision of reality that governs how practitioners define and relate to the many and varied components that make up that reality. Using this definition, the author presents a visual model using concentric spheres of increasing abstraction that rearrange T. S. Kuhn's four components of a disciplinary matrix that he articulated in the 1969 Postscript to The Structure of Scientific Revolutions. Based on this model and D'Amico's criteria for a coherent narrative, the study assesses the two primary paradigms, labeled the Object-Oriented paradigm and the Subject-Oriented paradigm, that existed in the fields …

Teamwork In Genetic Programming, Michael Lalena

Theses

This thesis attempts to solve food collection problems using genetic programming. The genetic program will evolve programs that mimic the way ants can collect food and bring it back to a nest. There are two special factors in this genetic program that make the ants work together in order to solve the problem, as opposed to each ant acting on its own. First, there will be a stream in the environment that the ants must cross to get to the food. Although all ants have the same program, some must move into the water and die, building a bridge for …

Regulation Of Algal Blooms In Antarctic Shelf Waters By The Release Of Iron From Melting Sea Ice, Peter N. Sedwick, Giacomo R. Ditullio

OES Faculty Publications

During summer 1995-96, we measured iron in the water column and conducted iron-enrichment bottle-incubation experiments at a station in the central Ross Sea (76°30'S, 170°40'W), first, in the presence of melting sea ice, and 17 days later, in ice-free conditions. We observed a striking temporal change in mixed-layer dissolved iron concentrations at this station, from 0.72-2.3 nM with sea ice present, to 0.16-0.17 nM in ice-free conditions. These changes were accompanied doubling of algal (diatom) biomass. Our incubation experiments suggest that conditions were iron-replete in the presence of sea ice, and iron-deficient in the absence of sea ice. We surmise …

Magnetic Field Decay In Single Radio Pulsars: A Statistical Study, Soma Mukherjee, Ajit Kembhavi

Physics & Astronomy Faculty Publications

We report on an extensive statistical study of single radio pulsar properties, which we undertook to estimate the decay timescale of pulsar magnetic fields. We synthesized a population of pulsars using assumed theoretical distributions of age, initial magnetic field, period of rotation, position, luminosity, and dispersion measure, taking into account the new distance model for pulsars as well as new velocity estimates. We also took into account the selection effects that characterize pulsar observations. We compared the simulated population with the observed single pulsar population using one- and two-dimensional Kolmogorov-Smirnov tests to obtain a lower bound of ∼160 Myr on …

Kinetics Of Autoxidative Polymerization Of Sunflowerseed Oil, Hüseyin Topallar, Yüksel Bayrak, Mehmet İşcan

Turkish Journal of Chemistry

The rates of polymerization of unhydrogenated and hydrogenated sunflowerseed oils were measured under atmospheric conditions in the various containers (glass, PET and metal). Polymerization rates showed a strong dependence on the degree of unsaturation and the light transmittance of the containers. The average molecular weights of polymerized oils were determined by viscosity measurements.The relationship between viscosity and average molecular weight was determined. It is seen that unhydrogenated sunflowerseed oil has a higher polymerization rate than hydrogenated oil samples in a glass container and they has higher viscosity values.

Apocarbonic Anhydrase-Enzymatic Determination Of Zinc In Fruit Juices, Ayşe Karagölge, Nazan Demi̇r, Yaşar Demi̇r, İrfan Küfrevi̇oğlu

Turkish Journal of Chemistry

In this study, a new enzymatic method for determining trace amount of zinc was employed on ten different fruit juices. The basis of the enzymatic method is that apocarbonic anhydrase regains its activity in proportion to the Zn^{2+} existing in a solution. Thus, the more activated the enzyme is in the medium, the higher the Zn^{2+} concentration in the solution will be. For this purpose, bovine carbonic anhydrase was purified from erythrocyte hemolisate by affinity chromatography. The Zn^{2+} bound to the enzyme was removed by of the purified enzyme against the solution of pyridine-2-6-dicarboxylic acid. Thus 100\% purified enzyme was …

The correlations between the surface properties of the modified cellulose papers with their toner compatibility were investigated. The surface tension components of the cellulosic films, their interfacial tension with the liquid drops and the work of adhesion components were calculated using van Oss-Good's One-Liquid contact angle approach. The electron donor (or Lewis base) \gamma^- components of the cellulosic films were found to represent the main interactions with the the electron acceptor (acidic) \gamma^+ components of the contacting liquids. Allyl ketene dimer (AKD) grafting of the cellulose affected the surface properties; the higher the substitution of the hydroxyl group, the smaller …

Features Of Graft Copolymer Formation Through Reaction Of Functionalized Polyolefins With Poly-\Epsilon-Caprolactam, Elisa Passaglia, Francesco Picchioni, Mauro Aglietto, Giocomo Ruggeri, Francesco Ciardelli

Turkish Journal of Chemistry

The reaction in the melt of polyolefins containing 2-diethylsuccinate groups (DES) with poly-\epsilon-caprolactam (PA6) to give a graft copolymer was investigated under different conditions. Even using a large excess of DES groups over the PA6 terminal amino groups the graft copolymer yield resulted only partial thus suggesting a kinetic control of the reaction. The effect of various catalysts was then examined taking into account results obtained in a model reaction between a low molecular weight amine and diethylsuccinate. The results are discussed in terms of side reactions and miscibility of the pristine polymers.
