Nuclear Vs. Coal In Bulgaria, Peter B. Manchev

Honors Theses

In early 2005 the government of Bulgaria commissioned the construction of a new nuclear power plant (NPP) near the town of Belene on the Danube border with Romania. The € 4 billion project will be executed by a consortium appointed in October 2006 by the National Electric Company led by the Russian Atomstroyexport. The work will be overseen by the architect-engineer of the plant, the American company WorleyParsons. The endeavor received a “green light” in December 2006 when the Nuclear Regulatory Agency of Bulgaria approved the Belene site for the construction of a new nuclear power plant.

The need for …

Excitable Boys: Gender And Redemption In The South, Emily Denton

Honors Theses

Literary critic Leslie Fiedler argues in Love and Death in the American Novel that within classic American novels there is a reoccurring pattern of the pure female and the aggressive male. These texts give rise to the reoccurring scenario in which an innocent young woman brings about the salvation of the sinful, aggressive male. These men are saved through the good works and kindness of these women. Fiedler argues further that these women are an embarrassment to their literary tradition; he says that they "proved almost everywhere a blight, a universal influence which was also a universal calamity" (45). These …

Chloroplast Dna Analysis Of Putative Chestnut Chinquapin Hybrids, Sarah Emmalyne Kennedy

Honors Theses

The American chestnut tree (Castanea dentata) has been reduced from a key canopy hardwood to an understory shrub by the chestnut blight disease. C. dentata shares similar morphological characteristics with the Allegheny chinquapin (C.pumila variety pumila) and the Ozark chinquapin (C.pumila variety ozarkensis). Before the chestnut blight epidemic, the easiest and most obvious means of separating species of American chestnut and chinquapins was based on habit or flower morphology. C.dentata existed as a large tree, while varieties of C. pumila existed as shrubs or small trees; C. dentata contains three nuts per bur, while varieties of C. pumila contain one …

Comparing Sulfur Transformations In Surface Soils Of Chattanooga Wetlands With Different Land Use Histories, Michael Mentz

Honors Theses

The purpose of this study was to assess whether high sulfur inputs in a local wetland had an effect on the functions of this wetland, i.e. an increased sulfate reduction rate and an increased sulfate concentration compared to a control wetland. Sulfate reduction rates were compared in two wetlands in Chattanooga, Tennessee during July and December 2007.These wetlands were known to have bad different histories of sulfur input via sulfates in precipitation or runoff.Through use of a 35S tracer technique, overall sulfate reduction rates could be compared for the two wetlands.Replicated sediment cores were collected from each wetland on the …

Challenging The Plantation Myth: A Comparison Of The Economic Histories And Relative Success Of Three Georgia Plantations From 1820 To 1870, Rachel Devan

Honors Theses

Though popular culture often makes the assumption that showplace plantations were the norm in the antebellum South, plantation archaeologists and historians have observed that the data say otherwise. Many of the Southern plantations that they study fall far short of the showplace ideal. In fact, a key role for plantation historians and archaeologists is to clear up the Americans' misconceptions about antebellum plantations by studying a range of plantation types and sizes. One way to accomplish this goal is to classify plantations under archaeological or historical study as either working plantations or showplace plantations based on economic data and use …

The Death Of The Virtuous Heroine As Social Criticism In Clarissa And Les Liaisons Dangereuses, Carmel Rosanna Nunan

Honors Theses

While Samuel Richardson meticulously documents the slow decline of his heroine in the novel Clarissa, other characters in the novel struggle to understand a death that for them has no rational explanation. The novel Les Liaisons Dangereuses by Choderlos de Laclos, also epistolary and published thirty-five years after Clarissa, allows for a similar interpretation. Contemporary French reactions to Madame de Tourvel’s death cannot compare to the English response elicited by Clarissa’s, but, like Richardson, Laclos also introduces certain social forces that seal his heroine’s fate from without while her own psychological experience of virtue works to destroy her …

Integration Of The Stereotype Content Model And Implicit Theories : A Dynamic Understanding Of Stereotyping Against Obese Individuals, Jenna Sorge

Honors Theses

The current paper integrated Fiske and colleague’s (2002) Stereotype Content Model (SCM) with the implicit theoretical approach to investigate the stereotyping process against obese individuals. Two studies evaluated the proposition that implicit theories of weight, the belief that weight is fixed (entity theorist) versus malleable (incremental theorist), and implicit person theories, the belief that human attributes are fixed or malleable, will predict how people categorize and discriminate against obese individuals. A pilot study found that entity and incremental theorists of weight have equal knowledge of societal stereotypes against obese individuals. Study 1 revealed those whose endorse an entity theory of …

The Penguins' Revolution: An Analysis Of Student Response To The Multi-Dimensional Chilean Educational Crisis, Abigail Hall

Honors Theses

Through exploration and analysis of economic, historical and political factors stemming from the authoritarian period (1973-1990) to the present day, this project offers an interdisciplinary explanation of the emergence of the "Penguin's Revolution" in Chile. In May-June 2006, 700,000 high school students paralyzed the Chilean education system by protesting in the streets, taking over schools and not attending classes. Students organized under the Coordinating Assembly of Secondary Students (ACES) demanded that the government take responsibility for providing universal high quality and equal education. The roots of student discontent lie in the multi-dimensional education crisis, generated by the semi-privatized, decentralized educational …

Pressure Perturbation Calorimetry And Guest-Host Chemistry Of Ndmg And N-Map With P-Sulfonatocalix[6]Arene, Cassandra Newell

Honors Theses

The aim of this project is to provide an explanation for recently obtained binding constants for two similar guest molecules, NDMG and N-MAP, with a p-sulfonatocalix[6]arene host in ammonium acetate buffer. This work was done primarily using pressure perturbation calorimetry, which is a technique that determines the coefficient of thermal expansion, α, which is in turn related to the solute molecule's effect on the order of the surrounding water molecules. A series of experiments were designed to test the effects of suspected confounding variables on the validity of PPC data. PPC was then used to study NDMG and N-MAP in …

The Effect Of Orientation To Growing Season Sunlight On Stomatal Parameters Of Q. Rubra In The Belgrade Lakes Region, Central Maine, Rachel G. Daly

Honors Theses

Stomatal frequencies of fossil-plant species are used to estimate past pCO2 levels based on the physiological functions of living taxa. Numerous studies have shown that there is an inverse relationship between pCO2 and stomatal frequency parameters. As levels of pCO2 increase, the Stomatal Density (SD) and Stomatal Index (SI) decrease. However, pCO2 is not the only factor affecting SD and SI values, which are a product of leaf growth and expansion. Stomatal characteristics differ between genera, and studies also have shown that SD and light intensity have a positive correlation. The present study hypothesizes that SD and SI are not …

Search For Novel Molecular Species Formed By Cold Rydberg Atoms In A Magneto-Optical Trap, Alexander Gill

Honors Theses

This describes a search for novel ultra-long-range molecular resonances between rubidium Rydberg atoms in a magneto-optical trap (MOT). We use the technique of photoassociative spectroscopy by directly scanning the wavelength of our Rydberg excitation laser about a 5p3/2 - 90p3/2 transition in a weak electric field and by scanning mm-waves about a 39sl/2 - 39p3/2 transition. The results of both of these surveys are inconclusive.

Using Azahetercyclic Electrophiles To Synthesize Novel Bicyclooxacalixarenes And Oxacalix[2]N-Hexylnaphthalimide[2]Naphthyridines, Doug Rooke

Honors Theses

Various bicyclooxacalixarenes, tricyclooxacalixarenes and oxacalix[2]N-hexylnapthalimide[2]naphthyridines are synthesized via SnAr condensation. This research has involved synthesis optimization. The oxacalix[2]N-hexylnaphthalimide[2]naphthyridines have exhibited host-guest binding in fluorescence experiments. These compounds have been characterized by NMR spectroscopy as well as single crystal X-ray diffraction.

Stranger In A Strange Land: The Struggle For Cultural And Personal Identity In Haruki Murakami's Hard-Boiled Wonderland And The End Of The World, Laura E. Smith

Honors Theses

In order to explicate Murakami's version of the official culture, I have analyzed the novel with the works of several different theorists. Primarily, I drew my own understanding of the official culture from Raymond Williams's examination of culture in Marxism and Literature. His terminology became helpful in writing about the operation of the System and the Town, though it did not define that operation precisely. Williams's work also introduced me to the theory behind the official culture's manipulation and exclusion of historical aspects in order to create their "official" version of history, from which the official culture draws its identity. …

Diode Lasers For Use In Experiments On Cold Rydberg Atoms, Bill Whitledge

Honors Theses

This project was to measure the atomic density of (85)Rb atoms in a magneto optical trap using a low-intensity probe laser. Additionally, a dark spontaneous force optical trap was constructed in an attempt to boost the trap density. The dark spot failed to appreciably increase the overall trap density (which remained steady at - N = 10^10 atoms/cm^3) but it did increase the density of dark-state atoms in the trap by an order of magnitude. This is a useful result since many experiments on cold Rydberg atoms involve exciting atoms starting in the ground state rather than the first excited …

The Pollination Biology And Mating System Of A Peripheral Population Of Witheringia Solanacea (Solanaceae), Timothy Miller

Honors Theses

Pollinator visitation rates over the life of a flower are determined by pollinator abundance and floral longevity. If flowers are not visited frequently enough, pollen limitation may occur, favoring the evolution of self-compatibility (SC). In plant species with varying SC levels, central populations often are self-incompatible (SI) and peripheral populations are SC. Witheringia solanacea (Solanaceae) is a species that follows this trend with the exception of one population in the Monteverde Cloud Forest Reserve, which is peripheral yet SI. I investigated this population using multiple techniques including floral bagging, pollinator observations, microsatellite analysis, and floral longevity manipulations. My results confirmed …

Interactions Of Electrons And Rydberg Atoms In Ultra-Cold Plasmas, Cristian Vesa

Honors Theses

This thesis discusses an experimental technique for investigating electron temperature control by Rydberg atoms in ultra-cold plasmas. The objective we set ourselves was twofold. Firstly, we sought to gain an insight into the processes whereby the creation of Rydberg atoms within the plasma lengthens the lifetime of the plasma. To this end, we created the plasma using a Littman dye laser and subsequently, at a variable time delay, we excited neutral atoms in the plasma to specific Rydberg states using a narrow bandwidth pulsed dye laser. Secondly, we employed radio-frequency (rf) electric fields to excite electron oscillations within the plasma …

Photochemical Generation And Intramolecular Chemistry Of Β-Alkoxycarbenes, Kimberly Graves

Honors Theses

The photolytic phenanthrene-based precursors for both β-methoxycarbene and β-ethoxycarbene were synthesized with and without a deuterium label attached to the a carbon. The incorporation of this deuterium label allowed distinction between a 1, 2-H shift and a 1, 2-O shift pathway to the respective alkyl vinyl ether, without the influence of a primary kinetic isotope effect. Photolyses of these precursors gave rearrangement products of the expected β-alkoxycarbenes. In the case of β-methoxycarbene, no methyl vinyl ether was observed due to its volatility. However, the appearance of aldehyde peaks in the NMR spectra, from an apparent further rearrangement to acetaldehyde through …

Effects Of Alcohol And Training On Exercise Performance And Muscle Recovery Biochemistry In The Brown Anole (Anolis Sagrei), Maryclaire Mcgovern

Honors Theses

Contrary to previous research, training may improve exercise performance in a lizard, the brown anole. A brief, two-week training period resulted in increased performance speed and distance before exhaustion in trained lizards. Trained lizards were also able to more effectively use leg glycogen stores, however each of these improvements were not found in lizards treated with alcohol. Liver glycogen concentrations were also lower in alcohol-treated lizards, and patterns of liver glycogen concentrations during recovery indicate some hepatic lactate gluconeogenesis.

Hamiltonian Constraint Analysis Of Vector Field Theories With Spontaneous Lorentz Symmetry Breaking, Nolan L. Gagne

Honors Theses

Recent investigations of various quantum-gravity theories have revealed a variety of possible mechanisms that lead to Lorentz violation. One of the more elegant of these mechanisms is known as Spontaneous Lorentz Symmetry Breaking (SLSB), where a vector or tensor field acquires a nonzero vacuum expectation value. As a consequence of this symmetry breaking, massless Nambu-Goldstone modes appear with properties similar to the photon in Electromagnetism. This thesis considers the most general class of vector field theories that exhibit spontaneous Lorentz violation-known as bumblebee models-and examines their candidacy as potential alternative explanations of E&M, offering the possibility that Einstein-Maxwell theory could …

Decisions To Abrogate Personal Liberty: Ethics Of Conscription In The United States, Jacqueline Shuttleworth Grady

Honors Theses

The military draft in the United States has been a controversial public policy in the past. Conscription has been used for six different wars; each draft has differed from the others because of the circumstances of the war for which it was enacted and because of the way in which it was implemented. Today, because of the wars the United States is fighting in Afghanistan and Iraq, a new public policy has developed, called stop loss. Stop loss affects only those people who have already served in the military, forcing them to remain in military service after the originally contracted …

Microhabitat Selection By The Tortoiseshell Limpet, Tectura Testudinalis (Müller), In Tide Pools On The Mid-Maine Coast, Emily R. Lyczkowski

Honors Theses

Microhabitat selection of the limpet Tectura testudinalis, an important grazer along the rocky Maine coast is examined using both mensurative and manipulative experiments. T. testudinalis substrate selection is essential to its survival in the unpredictable and harsh regime of the intertidal zone. At three sites studied in the Gulf of Maine, T. testudinalis selectively inhabits tidal pools and vertically oriented substrates. Both of these microhabitats reduce the degree of environmental stress (desiccation, extreme temperature, and hypersaline conditions) and predation experienced by individuals. Differences among sites are common, indicating the importance of varying environmental factors in regulating and influencing habitat selection …

Reactions Of Atomic Carbon With Acid Chlorides, Daniel B. Herrick

Honors Theses

This thesis is the first report of reactions of atomic carbon with acid chlorides. Carbon is known to react with phosgene to afford dichlorocarbene. We report a similar reaction with carbon and acid chlorides, generating alkylchlorocarbenes. We examine both the nature of the carbene products generated through deoxygenation and the general reactivity of carbon with the acid chlorides. We report two ways in which carbon reacts with acid chlorides. First, as expected from prior work with phosgene, carbon deoxygenates the carbonyl group yielding alkylchlorcarbenes, which rearrange as expected. Second, carbon abstracts the chlorine, and generates the acyl radical, which, in …

Separating People And Wildlife: Zoning As A Conservation Strategy For Large Carnivores, Courtney L. Larson

Honors Theses

Large carnivores are some of the world’s most difficult species to conserve because of their large spatial requirements, low population density, and high potential for conflict with humans. However, large carnivores are valuable for ecological, cultural, and ethical reasons. Carnivore management can take a wide variety of forms, including translocation, sterilization, livestock compensation programs, regulated hunting, improved livestock husbandry practices, and zoning, among others. The objective of this thesis was to conduct a comparative analysis of examples of zoning from around the world to examine whether it is an effective carnivore management strategy.

Analysis of twelve case studies showed that …

Diffeomorphism Invariance In General Relativity, John P. Chung

Honors Theses

Einstein's general relativity is a geometrical theory of gravity in which the effects of gravity are due to the curvature of space and time. In contrast, all of the other fundamental particle interactions are described as quantum field theories that are invariant under gauge transformations. In efforts to unify gravity with these other particle theories, it is desirable to reexpress Einstein's general relativity as a gauge theory. The gauge symmetry in Einstein's theory can be identified as invariance under diffeomorphism transformations. This work examines the nature of this symmetry, how it is implemented, and how it behaves as a gauge …

Advocating At The Margins: Women’S Ngos In China, Ling U

Honors Theses

The development of non-governmental organizations (NGOs) in China has been unprecedented in the past fifteen years. The 1995 Fourth World Conference on Women (FWCW) and parallel NGO Forum in Beijing, China, opened the door for the first time for the establishment of women’s NGOs in China. This paper examines the development of Chinese women’s NGOs with a particular focus on two organizations in Beijing for marginalized female populations: one focusing on lesbians and the other helping women with HIV/AIDS. I examine the structure and growth of each NGO; however, on a more personal level and perhaps more importantly, I use …

Effect Of Observed Biological And Non-Biological Movement On Human Action And Coordination, Walter L. Campbell

Honors Theses

Recently, it has been demonstrated that an individual’s rhythmic limb movements exhibit greater variability when viewing spatially incongruent biological limb movements, but not when viewing spatially incongruent non-biological movements. Some researchers have concluded that a ‘mirror-neuron system’ might mediate the intrinsic bidirectional link between perception and action underlying interpersonal, but not environmental, coordination (e.g., Kilner et al., 2003; Tognoli et al., 2007). The current study aimed to: 1) contest this recent finding; and 2) demonstrate that the self-organized entrainment processes of coupled oscillators can explain the differing influences of biological and non-biological movements. In the first experiment, participants intentionally coordinated …

Phosphorus Primer For Maine’S Lakes, Lindsay B. Philips

Honors Theses

Phosphorus plays a major role in aquatic systems and the life that they support. It is a macronutrient that constitutes 0.5lf microorganisms and zooplankton by mass. Phosphorus is of great importance in terrestrial, agricultural, and plant systems as a macronutrient, and when it comes to aquatic systems, we tend to look at phosphorus in terms of its influence on lake primary productivity. Lakes are often phosphorus sinks because they are maintained by hydrological sources that are capable of causing nutrient influx. To understand phosphorus cycling in lake systems, it is important to consider the many sources and forms of phosphorus …

Self-Destructive Behaviors Of Adolescent Girls And Boys, Carolyn A. Curtis

Honors Theses

From a social constructionist perspective linked with a feminist standpoint, I examine three forms of adolescent self-destructive behaviors: eating disorders, self-mutilation and substance abuse. The social construction of adolescents’ norms, values, and beliefs, as based upon their interactions with family, peers, and the media, helps explain these self-destructive actions. In addition to a comprehensive literature review, I interviewed five adults who work with adolescents in the state of Maine, and used these professionals’ experiences and knowledge to support the current theories pertaining to these acts of self-harm. To better understand what drives some adolescents to harm their own bodies, I …

Carbon Neutrality At Colby College, Jamie K. O’Connell

Honors Theses

Carbon neutral is a term used to describe any organization, entity, or process that has a net greenhouse gas (GHG) emissions level of zero (Dautremont-Smith et al. 2007a). Since carbon neutrality only requires a net greenhouse gas emissions level of zero, organizations do not need to eliminate all carbon pollution to become carbon neutral. Net emissions differ from gross emissions in that gross emissions are the sum of all emissions released by the individual or entity, whereas net emissions are equivalent to the gross emissions minus any carbon offsets. A carbon offset is any activity that reduces carbon emissions so …

In The Absence Of Family: How Ideas Of The Substitute Family In Honduran Children's Homes Shape Perception Of The Needs Of At-Risk Youth, Stephanie Bowman

Honors Theses

Through an interdisciplinary analysis of children’s homes in San Pedro Sula, Honduras, this project reflects on how conceptions of family affect the prioritization of the needs of the homes’ beneficiaries. One consequence of the impoverished nature of Honduras are orphaned, abandoned, mistreated, malnourished, abused, neglected and disowned children who have come to live in group children’s homes that, for the most part, meet their short-term physical needs. But what about children’s developmental, social and educational needs? In this study, we analyze what needs homes meet according to the kind of familial substitute they provide as either a group home or …
