High Level Of Fluctuating Asymmetry In The Byzantine Dogs From The Theodosius Harbor,Istanbul, Turkey, Abu B. Siddiq, Pere M Pares Casanova, Öğül Emre Öncü, Hakan Kar, Vedat Onar

Turkish Journal of Veterinary & Animal Sciences

Asymmetry, the abnormality of an organism or a part of it from its perfect symmetry, is represented by three different categories: fluctuating asymmetry, directional asymmetry, and antisymmetry. Fluctuating asymmetry attributes to random developmental variation of a morphological character, whereas directional asymmetry attributes one of the body sides to be more prominent than the other. Antisymmetry appears whenever one body side of a biological body shows greater morphological appearance than the other. Since more environmental stress often produces greater effect of fluctuating asymmetry, it can be a good indicator of physiological stress in the morphological characteristic of a biological being. Applying, …

Ewes (n = 40) were separated into four groups according to their reproductive status: maiden, empty, under continuous and restricted suckling ewes. Rams (n = 8) were separated into four groups according to their sexual experience: experienced-I and -II and inexperienced-I and -II. Each group of ewes was exposed at the same time to a different group of rams at 10-12 h intervals for 22 days, an injection of prostaglandin was given to ewes at the end of …

Functional Genetic Approaches To Provide Evidence For The Role Of Toolkit Genes In The Evolution Of Complex Color Patterns In Drosophila Guttifera, Mujeeb Olushola Shittu

Dissertations, Master's Theses and Master's Reports

Toolkit genes are set of genes that orchestrate the development of basic body plan of animals, and they are highly conserved in all animals. The co-option of the toolkit genes into the pigmentation pathway has led to the evolution of novel species. This study focuses on understanding how the complex color patterns in animals develop by using the Drosophila species in the quinaria group as models. We developed an mRNA in situ hybridization (ISH) protocol, which allowed us to study gene expression patterns in the abdomen of developing pupae of non-model Drosophila species (Chapter 2). Through ISH, we found that …

The Power Of The Panel: How American Comic Book Media Utilizes The Panel To Alter Audience Interaction, Austin Biese

Dissertations, Master's Theses and Master's Reports

This thesis traces the evolution of the panel across decades as well as various mediums. In one form, the panel becomes stretched when characters break the fourth wall to immerse readers in a new perspective on how the panel functions and creates meaning. In another form, comic book film adaptations comic imagery to instill a sense of nostalgia and to wink and nod at the audience, stretching the conventions of what the panel can be to impact the devoted audience. Lastly, in modern comic-reading apps, a ‘Smart Reading’ function remediates panels to provide an easier and unified path to read …

Investigation Of A Machine-Plant Interface For Extracting Rooted Invasive Aquatic Plants, Brad Baas

Dissertations, Master's Theses and Master's Reports

The current solutions for managing rooted aquatic invasive plants are time consuming, have negative environmental impacts, or are cost-limiting for management organizations. The most effective treatment method is hand pulling, but hand pulling is not a feasible solution for a whole lake. A new device, the invasive aquatic plant extractor, aims to replace human divers who hand pull plants with a mechanical system. The device implements a machine-plant interface that resembles the tines of a fork. These tines will be pushed linearly through the substrate, and then raised from the substrate with the plant caught in the tines. The primary …

The solid wastes comprises two main groups of materials: (i) fiber wastes (paper, food, wood, trimming, 61% of U.S. municipal solid waste) and (ii)uniquely challenging subset of plastic wastes (13%) that become a threat to global sustainability including dangers to marine and …

Evaluating Household Food, Energy, And Water Environmentally Oriented Anti-Consumption In The Us: Toward A Comprehensive Theory Synthesis, Jacob Slattery

Dissertations, Master's Theses and Master's Reports

Introduction – Everyday household activities using food, energy, and water (FEW) resources consumed in the US have perpetually contributed a large amount of carbon emissions into the atmosphere, amplifying the effects of climate change globally. These actions are embedded and routinized effectively at the individual level, resulting in habits inert to changes in household FEW behaviors more friendly to socio-environmental impacts. Public and voluntary policies could help shift perceptions of FEW household conservation, but a gap in environmental political and psychological research reveals a deficit in evidence examining the antecedents of the moral or personal norm concept.

Short-Term Fasting And Autonomic Control, Joshua Gonzalez

Dissertations, Master's Theses and Master's Reports

Obesity is a chronic metabolic disorder associated with increased risk of cardiovascular disease. Evidence suggests that chronic intermittent fasting improves cardiometabolic health and reduces arterial blood pressure. However, the mechanisms underlying the reductions in blood pressure and improved cardiovascular health observed from chronic fasting studies remain unclear. The autonomic nervous system has a central role in the regulation of blood pressure and is essential for cardiovascular homeostasis. We conducted a study to investigate how acute fasting influences autonomic control of blood pressure at rest and during stress. Twenty-five young, healthy, normal weight, normotensive participants were tested twice, once in the …

Advancement Of Full-Vector Variable-Temperature Magnetometry For Rock-Magnetic And Paleointensity Applications, Leonid Surovitskii

Dissertations, Master's Theses and Master's Reports

Data on the variation of the direction and strength of Earth’s ancient magnetic field (absolute paleointensity) provide crucial information into the mechanisms of the geodynamo and the Earth’s thermal history. However, the use of conventional methods and instrumentation for absolute paleointensity determination has been hampered by physicochemical alteration of the samples caused by multiple high-temperature cycles and long experiment durations. The reliability and efficiency of the measurement process can be improved by the measurement of the full remanent magnetization vector simultaneously with the temperature cycling of a sample. Such as approach can also substantially expand the scope of materials available …

Activation Scavenging Of Aerosol : Effect Of Turbulence And Aerosol-Composition, Abu Sayeed Md Shawon

Dissertations, Master's Theses and Master's Reports

The interaction of aerosol particles with solar radiation significantly contributes to the global radiation balance. The magnitude of this aerosol-radiation interaction, among other parameters, depends on different aerosol properties, including how readily these particles would act as cloud condensation nuclei (CCN). These properties are governed by the formation and scavenging processes of aerosol. This dissertation explores some of these scavenging processes.

Favorable humidity and preexisting aerosol particles acting as CCN are the sine qua non conditions to form cloud droplets in Earth’s atmosphere. Forming cloud droplets (known as activation), meanwhile, acts as a wet scavenging mechanism for those CCN. Given …

Estimating Red Wolf Ancestry In A Population Of Canids On Galveston Island, Texas, Tanner Barnes

Dissertations, Master's Theses and Master's Reports

Hybridization can be a conservation concern if genomic introgression leads to the loss of an endangered species’ unique genome, or when hybrid offspring are sterile or less fit then their parental species, but hybridization can also be an adaptive management tool if rare populations are severely inbred. One such species, the red wolf, is critically endangered in the United States, where all extant red wolves are descended from 14 founders which has contributed to an increase in inbreeding over time. Red wolves were considered extirpated from Texas in 1980, but before they disappeared, they hybridized with encroaching coyotes creating a …

Accuracy Of Self-Assessment In A Ninth Grade Earth Science Classroom, Alyssa Jacobson

A Hybrid Technique Using Modified Icp Algorithm For Faster And Automatic 2d &3d Microscopic Image Stitching In Cytopathologic Examination, Hülya Doğan, Eli̇f Baykal Kablan, Murat Eki̇nci̇, Mustafa Emre Erci̇n, Şafak Ersöz

Turkish Journal of Electrical Engineering and Computer Sciences

Due to the limitations of the light microscopic system such as limited depth of field and narrow field of view, entire sample areas are invisible and pathologists move the light microscope stage along the X - Y - Z axes with eye-hand coordination. In order to reduce the dependence on the pathologist and to allow whole sample areas to be examined in a short time without any control (without eye-hand coordination), this study creates 2D & 3D panoramic images with wide-view of sample in the light microscopic systems. According to our literature research, there is no study that creates 2D …

Learning Prototypes For Multiple Instance Learning, Özgür Emre Si̇vri̇kaya, Mert Yüksekgönül, Mustafa Gökçe Baydoğan

Turkish Journal of Electrical Engineering and Computer Sciences

Multiple instance learning (MIL) is a weakly supervised learning method that works on the labeled bag of instances data. A prototypical network is a popular embedding approach in MIL. They overcome the common problems that other MIL approaches may have to deal with including dimensionality, loss of instance-level information, and complexity. They demonstrate competitive performance in classification. This work proposes a simple model that provides a permutation invariant prototype generator from a given MIL data set. We aim to find out prototypes in the feature space to map the collection of instances (i.e. bags) to a distance feature space and …

Evaluation Of Archeal Growth On Complex Media And Antibiotic Regimes, Melanie Miller

Honors Program Theses

The first Archaea that were studied by scientists came from extreme environments such as fissures at the bottom of oceans where hydrothermal vents formed. It was perhaps surprising that later sampling of environmental DNA revealed Archaea inhabit normal environments as well, for example they are globally distributed in soils. These mesophilic soil species were only recently grown in laboratory pure cultures. In this study, we will expand on this work by feeding the community of soil microbes with various dilutions of tryptic soy broth and other complex media in combination with an antibiotic regime. This will allow us to compare …
