Comparison Of Glucose, Fructose And Sucrose Amperometric And Thermal Sensors For Detection Of Carbohydrates In Living Plant Tissue, Scott Mcadoo Jan 2015

Comparison Of Glucose, Fructose And Sucrose Amperometric And Thermal Sensors For Detection Of Carbohydrates In Living Plant Tissue, Scott Mcadoo

Legacy Theses & Dissertations (2009 - 2024)

Ecologists currently cannot test concentrations of carbohydrates in sap in vivo. Testing carbohydrates with current technology would require destructive tissue sampling. The tissue sampling involves large amounts of time and money to collect and test. Aphids are an insect that can bypass a tree’s passive immune system and feed off a phloem region for weeks. A series of enzymatic biosensors could be used to detect the concentration changes of specific carbohydrates. A calcium chelant can be added to defeat a tree’s immune system like an aphid. The detection of three carbohydrates, fructose, glucose and sucrose are involved in this study. …

Distributions And Formations Of Hono In The Troposphere, Dennis Pu

Legacy Theses & Dissertations (2009 - 2024)

Nitrous acid (HONO) is an important reactive nitrogen species and a precursor to the hydroxyl radical. It plays important roles in reactive nitrogen recycling and in photo-oxidant formation in the troposphere. However, much is still unknown about its formation mechanisms and distributions in the troposphere. This research is part of NOMADSS (Nitrogen, Oxidants, Mercury, and Aerosol Distributions, Sources and Sinks) field study contributed by over 10 research groups in the United States to investigate the tropospheric chemistry of reactive nitrogen, mercury, oxidant and aerosols. One of the goals was to study the HONO distribution and formation mechanisms in the troposphere. …

Characterization Of Metallic And Semimetallic Oxide Nanoparticles In Industrial Wastewater And Associated Toxicity, Gary Roth Jan 2015

Characterization Of Metallic And Semimetallic Oxide Nanoparticles In Industrial Wastewater And Associated Toxicity, Gary Roth

Legacy Theses & Dissertations (2009 - 2024)

Engineered nanomaterials (ENMs) play an increasing role in manufacturing and consumer products. Currently, there is no standard approach to studying ENM toxicity, and a growing body of literature suggests that ENMs may have toxicity differing from similar compounds in bulk or dissolved form. I examined ENMs used in the semiconductor manufacturing process called chemical-mechanical planarization (CMP) for their properties, removal in the wastewater treatment system (WWT), in-vitro toxicity, and location post-inhalation in-vivo. It was found that ENMs in CMP slurries have morphology determined by their elemental composition, but assessment of size and concentration can differ substantially between accepted techniques. Particles …

Molecular Dynamics Simulations Of Small Systems To Improve Base Pairing Parameters Of The Amber-99 Force Field, Angelo Christopher Setaro Jan 2015

Molecular Dynamics Simulations Of Small Systems To Improve Base Pairing Parameters Of The Amber-99 Force Field, Angelo Christopher Setaro

Legacy Theses & Dissertations (2009 - 2024)

Simulations of biochemical systems are being increasingly used to further our understanding of those systems. In broad strokes, chemical simulations can be broken into two categories, those that are rooted in a quantum mechanical approach and those that are classically rooted. Molecular dynamics is one such classical method, which propagates motion of a chemical system via repeatedly solving Newton’s Laws of motion. This approach is less computationally intensive than the quantum mechanical methods and allows for the simulation of systems of tens of thousands of atoms, if not more.

The Implementation Of Judicial Policy In Crime Laboratories : An Examination Of The Impact Of Melendez-Diaz V. Massachusetts, Catherine L. Bonventre Jan 2015

The Implementation Of Judicial Policy In Crime Laboratories : An Examination Of The Impact Of Melendez-Diaz V. Massachusetts, Catherine L. Bonventre

Legacy Theses & Dissertations (2009 - 2024)

In Melendez-Diaz v. Massachusetts (2009), the United States Supreme Court held that the Sixth Amendment right to confront adverse witnesses includes the right to confront forensic analysts who produce affidavits certifying the results of forensic examinations used against defendants at trial. The decision thus invalidated the practice of substituting forensic laboratory reports for live testimony in criminal trials. Melendez-Diaz was a divided decision in which four dissenting Justices predicted onerous practical consequences for the practice of forensic science in the United States. Through a web-based survey and semi-structured interviews, this dissertation explored the practical impact of the decision on crime …

Identity Compatibility, Career Adaptability, And Adaptive Coping As Predictors Of College Women's Commitment In Stem Majors, Michelle Murray Jan 2015

Identity Compatibility, Career Adaptability, And Adaptive Coping As Predictors Of College Women's Commitment In Stem Majors, Michelle Murray

Legacy Theses & Dissertations (2009 - 2024)

The ‘leaky pipeline’ is a metaphor often used to describe the progressive and persistent phenomenon that occurs when women who have initially planned on pursuing STEM careers drop out before a career is established (Cronin & Roger, 1999). Women pursuing STEM occupations often receive messages that they do not belong or are not expected to succeed in the field, which can negatively impact one’s academic performance, increase psychological stress, and influence one’s persistence within a field of study (Steele & Aronson, 1995; London, Downey, Bolger & Velilla, 2005). Using career construction theory (Savickas, 2013) as a framework, the current study …

Phase Imaging Using X-Ray Optics, Bushra Kanwal Jan 2015

Phase Imaging Using X-Ray Optics, Bushra Kanwal

Legacy Theses & Dissertations (2009 - 2024)

Conventional x-ray imaging is a widely used imaging technique in medical diagnostics as well as material analysis. It utilizes only absorption-contrast imaging, which records intensity attenuation due to absorption. A major limitation of this technique for medical imaging is the poor contrast of weakly absorbing details in the soft tissue. Mammography and angiography are two examples where improved contrast is required. In the quest for better contrast in x-ray imaging, a number of different phase contrast imaging techniques have been explored. Phase contrast imaging offers an improvement over traditional absorption contrast because the x-ray wave field traversing an object experiences …

White Privilege In Teacher Education : A Critical Analysis Of Discourse, Kenneth P. Sider Jan 2015

White Privilege In Teacher Education : A Critical Analysis Of Discourse, Kenneth P. Sider

Legacy Theses & Dissertations (2009 - 2024)

This inquiry seeks to understand how preservice teachers interact with White privilege during a teacher education course dedicated to diversity and teaching. By pairing grounded theory with phenomenology, insights into participants’ pre-existing beliefs around race and Whiteness are examined. Given the cultural mismatch between an increasingly diverse public school student population and the historically stable White preservice teacher population, a closer look at persistent and resistant linguistic phenomena undergirding White dominance in the educational setting is useful. Participants’ pre- and post-term papers are used to anchor the research, and an asynchronous, online, peer-mediated discussion of bell hooks’ autoethnographic essay “Learning …

The Impact Of Seed Layer Structure On The Recrystallization Of Ecd Cu And Its Alloys, Brendan B. O'Brien

Legacy Theses & Dissertations (2009 - 2024)

Despite the significant improvements originally offered by the use of Cu over Al as the interconnect material for semiconductor devices, the continued down-scaling of interconnects has presented significant challenges for semiconductor engineers. As the metal line widths shrink, both the conductivity and reliability of lines decrease due to a stubbornly fine-grained microstructure in narrow lines.

A Novel Method For Studying Gene Regulatory Elements In Vivo Reveals Essential Roles For Intron Splicing In Neurofilament Gene Expression, Chen Wang Jan 2015

A Novel Method For Studying Gene Regulatory Elements In Vivo Reveals Essential Roles For Intron Splicing In Neurofilament Gene Expression, Chen Wang

Legacy Theses & Dissertations (2009 - 2024)

Axon outgrowth requires coordinated expression of critical cytoskeletal genes in response to extracellular cues. The spatial and temporal expression of these genes is regulated transcriptionally and posttranscriptionally. Such regulation is largely mediated through the activity of cis-regulatory elements within the cytoskeletal DNAs and RNAs, which recruit specific sets of trans-factors such as DNA- and RNA-binding proteins, as well as microRNAs. To identify the functionally active cis-elements, characterize their dynamically changing sets of trans-factors, and investigate the association between the two sets of regulators in the context of an intact developing nervous system, one needs to combine appropriate in vivo strategies …

Advanced Raman Spectroscopic Methods For Structural Characterization Of Amyloid Fibrils And Bionanotubes, Valentin Sereda Jan 2015

Advanced Raman Spectroscopic Methods For Structural Characterization Of Amyloid Fibrils And Bionanotubes, Valentin Sereda

Legacy Theses & Dissertations (2009 - 2024)

Amyloid aggregation is a specific form of protein misfolding and self-assembly related to several degenerative pathologies like Alzheimer's and Parkinson's diseases, type-II diabetes, etc. This association with deadly diseases has made amyloid fibrils the focus of intensive research for many decades. Most recently, a significant interest to protein fibrils was also due to the application of the remarkable self-assembling capabilities to form well-structured nano-biomaterials. Self-assembly of short peptide sequences into well-organized structures is another important strategy for bottom-up fabrications of nano-biomaterials. One of the most commonly used building blocks is diphenylalanine, a short dipeptide that has been identified as playing …

Vitamin D Signaling And The Impact On Mouse Mammary Gland Epithelium, Donald Grant Matthews Jan 2015

Vitamin D Signaling And The Impact On Mouse Mammary Gland Epithelium, Donald Grant Matthews

Legacy Theses & Dissertations (2009 - 2024)

A strong correlation between vitamin D deficiency and increased breast cancer incidence and mortality has been well established, leading researchers to further examine the possibility of using vitamin D in treatment and prevention strategies. Our long term goal is to elucidate the mechanisms by which vitamin D pathway signaling impacts on breast cancer. Generation of the high-affinity vitamin D receptor (VDR) ligand 1,25-dihydroxyvitamin D (1,25-D) from 25-hydroxyvitamin D (25-D) is mediated by CYP27B1 which is present and developmentally regulated in multiple tissues including the mammary gland. We utilized transgenic mouse models combined with diet-induced vitamin D deficiency to determine whether …

3d-Bioengineering Of The Conventional Outflow Tract For High Throughput Drug Or Gene Transfer Screening For Glaucoma Treatment, Cula Nolise Dautriche Jan 2015

3d-Bioengineering Of The Conventional Outflow Tract For High Throughput Drug Or Gene Transfer Screening For Glaucoma Treatment, Cula Nolise Dautriche

Legacy Theses & Dissertations (2009 - 2024)

Among ocular pathologies, glaucoma remains the second leading cause of blindness. The molecular mechanisms that lead to glaucoma have been attributed to damage of the conventional outflow tract. Conventional outflow tissues, a composite of the trabecular meshwork and the Schlemm's canal, regulate and maintain homeostatic responses of aqueous humor outflow. In glaucoma, drainage of aqueous humor into the Schlemm's canal is hindered, leading to an increase in intraocular pressure (IOP). That increase in IOP is directly correlated with retinal ganglion cell death, eliminating the relay of visual information to the thalamus and visual cortex, leading to blindness. Although disturbance in …

Phase Imaging Using Focusing Polycapillary Optics, Sajid Bashir Jan 2015

Phase Imaging Using Focusing Polycapillary Optics, Sajid Bashir

Legacy Theses & Dissertations (2009 - 2024)

The interaction of X rays in diagnostic energy range with soft tissues can be described by Compton scattering and by the complex refractive index, which together characterize the attenuation properties of the tissue and the phase imparted to X rays passing through it. Many soft tissues exhibit extremely similar attenuation, so that their discrimination using conventional radiography, which generates contrast in an image through differential attenuation, is challenging. However, these tissues will impart phase differences significantly greater than attenuation differences to the X rays passing through them, so that phase-contrast imaging techniques can enable their discrimination.

Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta Jan 2015

Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta

Legacy Theses & Dissertations (2009 - 2024)

Many planning and land use decisions in New York State are controlled at the local (town or municipal) level, not an optimal scale for planning and implementing resource conservation management. Watershed boundaries provide a more ecologically meaningful scale for conservation, because they capture a full range of natural ecosystem processes that span political boundaries. However, defining an urban watershed is complicated by stormwater infrastructure, so standard topographic watershed boundaries may be inadequate for urban resource conservation even when applied at the watershed scale. Storm-watersheds distort both municipal and watershed boundaries, because the flows are redirected in ways that are often …

Genome-Scale Analyses Of Transcription And Transcriptional Regulation In Bacteria, Devon Marie Fitzgerald Jan 2015

Genome-Scale Analyses Of Transcription And Transcriptional Regulation In Bacteria, Devon Marie Fitzgerald

Legacy Theses & Dissertations (2009 - 2024)

The textbook model of bacterial transcription regulation posits that promoters occur immediately upstream of genes and that transcription factors (TFs) modulate transcription through promoter-proximal binding. However, the recent application of unbiased genome-wide approaches, such as ChIP-seq and RNA-seq, has revealed a much more complex picture, including TF binding and transcription initiation occurring in unexpected locations. This dissertation describes the use of deep sequencing-based approaches to evaluate the genome-wide binding of transcription-related proteins and identify locations of transcription initiation. I have assessed the genome-wide binding of three Escherichia coli TFs and an alternative σ factor. Additionally, I have analyzed genome-wide patterns …

Expecting The Unexpected : A Precautionary Principle Addressing Unconsidered Dangers, John Raymond Milanese Jan 2015

Expecting The Unexpected : A Precautionary Principle Addressing Unconsidered Dangers, John Raymond Milanese

Legacy Theses & Dissertations (2009 - 2024)

Most precautionary principles discussed in the regulatory literature argue that one ought to be more risk averse when one is uncertain about the probability of some sig- nificant danger. I explore a new kind of precautionary principle, one that addresses avoiding dangers we did not explicitly consider at all. Since it is unclear how uncon- sidered dangers could be avoided, I sketch a methodology for identifying situations where unconsidered dangers seem especially likely, by drawing from the literature in psychology on heuristics and biases and evaluating our cognitive “blind spots.”

Landowner Knowledge And Opinions Of Invasive Species And Their Management Surrounding A Suburban Nature Preserve, Christina Mclaughlin Jan 2015

Landowner Knowledge And Opinions Of Invasive Species And Their Management Surrounding A Suburban Nature Preserve, Christina Mclaughlin

Legacy Theses & Dissertations (2009 - 2024)

Invasive species are a growing human-caused threat to biodiversity around the globe as they are moved both accidentally and intentionally through trade routes. The human component of conservation management is especially critical in invasive species, as human awareness is key to preventing and rapidly responding to new introductions. Yet the social component of management is poorly studied, even as outreach efforts continue to grow in an effort to gain public support. This study attempts to understand public knowledge and opinions toward invasive species and their management through an online survey of neighboring landowners to a suburban nature preserve, the Albany …

911 : Help Or Hindrance In Reducing Repeat Victimization, Kay Elizabeth Lang Jan 2015

911 : Help Or Hindrance In Reducing Repeat Victimization, Kay Elizabeth Lang

Legacy Theses & Dissertations (2009 - 2024)

In my dissertation I examine two pieces of criminological knowledge in order to explore the point at which they converge. First, crime victims call the police for a variety of reasons, one of which is to stop future attacks; and second, research suggests that previous victimization is a significant predictor of future victimization. In my research I seek to expand current knowledge about repeat victimization using the National Crime Victimization Survey (NCVS). I examine repeat victimization at the individual level, with crimes of violence, and at the household level, by examining residential burglary. But my project expands on existing knowledge …

Bioengineering In Vitro Human Trabecular Meshwork Models For Glaucoma Therapeutic Screening, Karen Yud Torrejon Jan 2015

Bioengineering In Vitro Human Trabecular Meshwork Models For Glaucoma Therapeutic Screening, Karen Yud Torrejon

Legacy Theses & Dissertations (2009 - 2024)

Glaucoma refers to a group of slowly progressing eye disorders that lead to damage to the optic nerve, resulting in irreversible vision loss. Recent statistics by the World Health Organization places glaucoma as a leading cause of blindness worldwide, affecting nearly 80 million people. Lowering intraocular pressure (IOP) is currently the only effective target for therapeutic intervention in glaucoma. IOP is mostly controlled by the outflow of the aqueous humor (AH) through the trabecular meshwork (TM). The TM and adjacent endothelium of Schlemm’s canal, known as the conventional outflow-tract, control AH outflow and thus determine IOP.

Vitamin D Regulates Metabolic Gene Expression, Glutamate And Glutamine Utilization, And Mitochondrial Function In Human Mammary Epithelial Cells, Sarah Beaudin

Legacy Theses & Dissertations (2009 - 2024)

Exposure to 1,25-Dihydroxyvitamin D (1,25D) decreases proliferation and induces differentiation in telomerase-immortalized human mammary epithelial (hTERT-HME1) cells. The studies described here addressed the mechanisms by which these effects are exerted. Microarray experiments were used to identify a subset of metabolic genes and pathways that are altered by 1,25D. In particular, genes involved in glutamate and glutamine utilization, including SLC1A1 and GLUL, were studied. Interestingly, qPCR analysis in a panel of six cell lines, representing either normal epithelial tissue or breast cancer, demonstrated diverse gene expression responses to 1,25D. In an isogenic model of mammary cell transformation, 1,25D altered gene expression …

Foraminiferal Beta 2-Tubulin And Microtubule To Helical Filament Transition In Reticulomyxa Filosa, Ingrid Ann Hahn Jan 2015

Foraminiferal Beta 2-Tubulin And Microtubule To Helical Filament Transition In Reticulomyxa Filosa, Ingrid Ann Hahn

Legacy Theses & Dissertations (2009 - 2024)

Foraminifera have unusually fast dynamic movements resulting in the reorganization of the microtubule cytoskeleton (Travis and Bowser, 1988; Travis et al., 1983). We are interested in using Reticulomyxa filosa as a model to investigate the mechanisms and factors that regulate such fast microtubule assembly/disassembly rates (Chen and Schliwa 1990; Travis and Bowser, 1991; Welnhofer and Travis, 1996). Compared to conventional microtubule assembly and disassembly models, foraminifera tubulin can exist in another assembly state termed helical filaments. A novel form of tubulin, β2, in foraminifera is likely critical to these unusual microtubule properties. This thesis investigates Reticulomyxa filosa, a freshwater foraminifera …
