Grass Component Effect On Soil Physical Properties In An Organic Crop Rotation, Emily Leslie Romano
Grass Component Effect On Soil Physical Properties In An Organic Crop Rotation, Emily Leslie Romano
Graduate Theses, Dissertations, and Problem Reports (ETD)
In the past few decades, organic productions systems have become increasingly popular due to rising environmental awareness. Much research has been done on crop rotations and fertilization in conventional agricultural systems, but because organic management practices are often different from those in conventional systems, much is unknown about the effect of organic management practices on soil quality. Composted manure and a temporary grass component within an organic crop rotation may be capable of improving soil quality, and may be particularly important in the absence of synthetic chemical inputs. The objective of this research was to evaluate soil quality changes in …
Elucidation Of The Early Steps Of Ergot Alkaloid Synthesis By Pathway Reconstruction In Aspergillus Nidulans, Katy Ryan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Ergot alkaloids are pharmaceutically and agriculturally important secondary metabolites produced by several species of fungi in the Clavicipitaceae (order Hypocreales) and Trichocomaceae (order Eurotiales). Ergot alkaloid pathways vary among producers due to genetic variation within ergot alkaloid synthesizing (eas) gene clusters. However, the early steps of the pathway leading to the formation of chanoclavine-I appear to be evolutionarily conserved among producers. Chanoclavine-I synthesis occurs in at least five steps, and knockout and heterologous expression studies have demonstrated that four genes, dmaW, easF, easE, and easC, are required for pathway steps prior to chanoclavine-I formation. It was unknown whether these genes …
Low-Power And Programmable Analog Circuitry For Wireless Sensors, Brandon David Rumberg
Low-Power And Programmable Analog Circuitry For Wireless Sensors, Brandon David Rumberg
Graduate Theses, Dissertations, and Problem Reports (ETD)
Embedding networks of secure, wirelessly-connected sensors and actuators will help us to conscientiously manage our local and extended environments. One major challenge for this vision is to create networks of wireless sensor devices that provide maximal knowledge of their environment while using only the energy that is available within that environment. In this work, it is argued that the energy constraints in wireless sensor design are best addressed by incorporating analog signal processors. The low power-consumption of an analog signal processor allows persistent monitoring of multiple sensors while the device's analog-to-digital converter, microcontroller, and transceiver are all in sleep mode. …
"I Feel That Our House Is The Future As Well As The Past": Architecture, Monumentality And Form In The Modernist Novel, Harrington Weihl
"I Feel That Our House Is The Future As Well As The Past": Architecture, Monumentality And Form In The Modernist Novel, Harrington Weihl
Graduate Theses, Dissertations, and Problem Reports (ETD)
Questions of how literary modernism and literary realism can be distinguished from one another, particularly in the transitional period at the beginning of the twentieth century, are central concerns in the study of literature. I argue here that in E.M. Forster's 1913 novel Howards End, the 'monumentality' of the titular house is the key to its inclusion in the modernist canon. This monumentality is incomplete, I claim, and as such formally replicates the impossibility of comprehending or representing modern life. I conclude with a similar reading of Elizabeth Bowen's 1929 novel The Last September in order to demonstrate that this …
Evaluation Of Hydrotreated Biofuels For Use In Naval Diesel Engines, Cory J. Morgan
Evaluation Of Hydrotreated Biofuels For Use In Naval Diesel Engines, Cory J. Morgan
Graduate Theses, Dissertations, and Problem Reports (ETD)
In recent years the U.S. Navy has developed several energy goals to displace foreign petroleum-derived fuels. One of these goals involves replacing existing fuels with alternative hydrotreated biofuels. Hydrotreated biofuels are a second generation renewable diesel fuel and generally have similar fuel properties and characteristics as petroleum-derived fuels. The U.S Navy is currently investigating several alternative biofuels including HRJ5, HRD76, DSH76, and HDCD76. To ensure these fuels perform similarly to or better than petroleum fuels, the U.S. developed a fuel specification program. Part of this program involves preliminary evaluations of the alternative biofuels in a laboratory environment to identify negative …

Nano-Derived Sensors For High-Temperature Sensing Of H2, So2 And H2s, Engin Ciftyurek
Nano-Derived Sensors For High-Temperature Sensing Of H2, So2 And H2s, Engin Ciftyurek
Graduate Theses, Dissertations, and Problem Reports (ETD)
The emission of sulfur compounds from coal-fired power plants remains a significant concern for air quality. This environmental challenge must be overcome by controlling the emission of sulfur dioxide (SO2) and hydrogen sulfide (H2S) throughout the entire coal combustion process. One of the processes which could specifically benefit from robust, low cost, and high temperature compatible gas sensors is the coal gasification process which converts coal and/or biomass into syngas. Hydrogen (H2), carbon monoxide (CO) and sulfur compounds make up 33%, 43% and 2% of syngas, respectively. Therefore, development of a high temperature (>500°C) chemical sensor for in-situ monitoring …
Il-15 Signaling In Skeletal Muscle: Implications In Modulation Of Pgc-1alpha And Mitochondrial Biogenesis, Grant C. O'Connell
Il-15 Signaling In Skeletal Muscle: Implications In Modulation Of Pgc-1alpha And Mitochondrial Biogenesis, Grant C. O'Connell
Graduate Theses, Dissertations, and Problem Reports (ETD)
Altering interleukin-15 (IL-15) signaling through ablation of interleukin receptor alpha (IL-15Ralpha) in the IL-15Ralpha global KO mouse has been shown to result in an oxidative shift in skeletal muscle characterized by enhanced fatigue resistance and increases in mitochondrial density. However, the mechanism of this phenomenon is unclear, as IL-15 signaling in skeletal muscle has been virtually unexplored. It has been previously suggested that loss of IL-15Ralpha in the global KO mouse directly results in an increase in muscle IL-15 secretion, and this increase in secreted IL-15 acts on skeletal muscle in an autocrine fashion, directly stimulating pro-oxidative remodeling. Thus, the …
Investigating Balanced Time Perspective In Adults Across The Life Span, Nipat Bock Pichayayothin
Investigating Balanced Time Perspective In Adults Across The Life Span, Nipat Bock Pichayayothin
Graduate Theses, Dissertations, and Problem Reports (ETD)
The current study investigated balanced time perspective (BTP) in adults across the life span (N = 400, 43.3% males). Boniwell and Zimbardo (2004) defined BTP as the flow and flexibility of connecting to the past, living in the present, and looking forward to the future and argued that is an optimal time perspective associated with happiness and well-being. Using Time Attitude Scale (Mello & Worrell, 2012), younger (M = 26.09 years), middle-aged (M = 46.72 years), and older (M = 64.25 years) adults subjective ratings of their positive and negative attitudes towards the past, present, and future were used to …
High Salt Diet-Induced Alteration In Vascular Reactivity In Wild-Type And Adenosine A2a Receptor Null Mice, Isha Pradhan
High Salt Diet-Induced Alteration In Vascular Reactivity In Wild-Type And Adenosine A2a Receptor Null Mice, Isha Pradhan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Alteration in vascular reactivity serves as a marker for cardiovascular disease. Enhancement of vasodilatory response through adenosine A2A receptor (A2AAR) signaling against high salt (HS) diet is speculated to be an adaptive response as salt-sensitive rats showed upregulation of A 2AAR and cyp-epoxygenases but salt-resistant rats did not. However, no direct evidence is available showing the compensatory role of A2A AR signaling upon salt loading. For this, understanding the functional and biochemical outcome of HS diet on vascular tone regulation and its underlying signaling mechanism in the presence and absence of A 2AAR is required. This dissertation was carried out …

Autonomous Formation Flight is a key approach for reducing greenhouse gas emissions and managing traffic in future high density airspace. Unmanned Aerial Vehicles (UAV’s) have made it possible for the physical demonstration and validation of autonomous formation flight concepts inexpensively and eliminates the flight risk to human pilots. This thesis discusses the design, implementation, and flight testing of three different formation flight control methods, Proportional Integral and Derivative (PID); Fuzzy Logic (FL); and NonLinear Dynamic Inversion (NLDI), and their respective performance behavior. Experimental results show achievable autonomous formation flight and performance quality with a pair of low-cost unmanned research fixed …
Investigating The Role Of Mechanical Properties In Biological Systems, Nicole Shamitko-Klingensmith
Investigating The Role Of Mechanical Properties In Biological Systems, Nicole Shamitko-Klingensmith
Graduate Theses, Dissertations, and Problem Reports (ETD)
There is considerable interest in measuring, with nanoscale spatial resolution, the physical and material properties of biological membranes and whole cells because of their role in the physiology of living systems. The atomic force microscope (AFM) has proven to be particularly well-suited for biological studies because samples can be maintained in near physiological conditions to preserve sample integrity (such as in a buffer solution at a physiologically relevant pH or temperature), and the imaging process is relatively nondestructive. In this work, the mechanical properties of supported lipid bilayers and neurons were examined using AFM-based techniques. Specifically, tapping mode AFM-based techniques …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent and progressive airflow limitation caused due to chronic inflammation in the lungs. Approximately 15 million adults in the United States (U.S.) are estimated to be diagnosed with COPD and an equal number may have undiagnosed COPD. Challenges to COPD management include high prevalence of inflammation-related multimorbidity among individuals with COPD. The association between multimorbidity, existing COPD management and role of novel therapies with anti-inflammatory properties (e.g. statins) in improving COPD-specific outcomes is not well researched. Therefore, the purpose of this study was to use real-world observational data to provide a comprehensive …

Grit In College Students: Associations With Achievement And Parental Influences, Katelyn R. Black
Grit In College Students: Associations With Achievement And Parental Influences, Katelyn R. Black
Graduate Theses, Dissertations, and Problem Reports (ETD)
The primary goal of this study was to investigate the relationship of Duckworth and colleagues' (2007) construct of `grit' with academic achievement, parent socialization behaviors and beliefs, and previously established academic risk factors (e.g., low income, level of parent education). A total of 97 student-parent dyads completed online questionnaires, providing grit scores, attachment scores, the parents' grit socialization habits, and demographic information. Pearson's correlations revealed associations between student grit, GPA, and parents' reports of grit socialization. Multiple linear regressions revealed that grit uniquely predicted GPA above and beyond parent income. In addition, grit did moderate the relation between attachment and …

Analyzing Fracture Stimulation Of Middle Devonian Strata In Clearfield County Pennsylvania Using A 3d Geomechanical Fault Model And Microseismic, Cole E. Bowers
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Middle Devonian Marcellus Formation in the Appalachian basin is a world class unconventional reservoir. The Marcellus Formation in Clearfield County, Pennsylvania has comparable thickness, depth, reservoir pressure, total organic carbon, and thermal maturity in comparison to other areas within the Appalachian basin. However, lower natural gas production is observed in this area. Structural complexity, natural fracturing, and rock mechanics in the study area negatively affect fracture stimulation, and can potentially hinder gas production. Two fault models using depth converted 3D seismic highlight structural complexity. A geomechanical model, and microseismic analysis using r(t) plots, and b-values highlight effects of natural …
Biomass Production, Composition, And Ethanol Potential Of Switchgrass Grown On Reclaimed Surface Mines In West Virginia, Carol A. Brown
Biomass Production, Composition, And Ethanol Potential Of Switchgrass Grown On Reclaimed Surface Mines In West Virginia, Carol A. Brown
Graduate Theses, Dissertations, and Problem Reports (ETD)
Growing crops for biofuel production on agricultural land has caused a debate between whether we should grow corn grain on productive, agricultural lands to feed a growing human population or to fuel our vehicles. This has increased interest in growing cellulosic biofuel feedstocks on marginal lands. Switchgrass (Panicum virgatum L.), a warm-season perennial grass, has been shown to be a viable bioenergy crop because it produces high yields on marginal lands under low water and nutrient conditions. West Virginia contains immense acreages of reclaimed surface mine lands and could offer enough area for the production of switchgrass as a feedstock …
Between The Local And The National: The Free Territory Of Trieste, "Italianita," And The Politics Of Identity From The Second World War To The Osimo Treaty, Fabio Capano
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation examines the politicized use of the city of Trieste and its surrounding territory, a cosmopolitan municipality that became the theatre of one of the most heated disputes of the early Cold War years. Scholars have extensively studied the diplomatic dimension of the confrontation between Italy and former Yugoslavia, yet many have largely neglected the significance of the broader political process that led to the Osimo Treaty of 1975, the final settlement of Italy's eastern border. This dissertation reaffirms the importance of the Triestine territory as a contested socio-political space that experienced the logic of both Cold War containment …

Relation Of Interpersonal Conflict Behaviors To Emotion Dysregulation And Ptsd In Adolescents With A History Of Betrayal Trauma, Vanessa M. Jacoby
Relation Of Interpersonal Conflict Behaviors To Emotion Dysregulation And Ptsd In Adolescents With A History Of Betrayal Trauma, Vanessa M. Jacoby
Graduate Theses, Dissertations, and Problem Reports (ETD)
Posttraumatic stress disorder (PTSD) is a disorder that develops in response to exposure to a traumatic stressor. Although this is the most well known diagnosis for individuals who have difficulties after a traumatic event, research documents numerous difficulties and psychopathology that can result from traumatic events, many of which do not fit the DSM-IV criteria of PTSD. Specifically, severe, chronic, interpersonal trauma tends to have a different pattern of effects on individuals than does acute, non-interpersonal trauma. This is particularly true for children (e.g., van der Kolk, Roth, Pelcovitz, Sunday, & Spinazzola, 2005). Because of this, the construct of Developmental …
Estimating Ultimate Recovery In Shale Wells Based On Facts, Faegheh Javadi
Estimating Ultimate Recovery In Shale Wells Based On Facts, Faegheh Javadi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Natural gas, as one of the nation's major energy sources plays a vital role in the US energy mix. In recent years, the production from Shale has focused much attention on this source of hydrocarbon. As an essential step for the production planning, natural gas professionals estimate production and ultimate recovery (EUR) throughout the life of wells. The fluid production rate (q) usually varies as a function of rock properties, well, and completion design parameters. The variation associated with these parameters is a source of uncertainty in estimating the long term production for unconventional reservoirs.;A number of methodologies have been …
A Spatial And Economic Analysis For Land Conservation Planning, Sudiksha Joshi
A Spatial And Economic Analysis For Land Conservation Planning, Sudiksha Joshi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Rapid loss of biodiversity has been mainly attributed to the loss of habitat and habitat fragmentation. Conservation efforts have increased over the years but the rate of biodiversity loss has yet to slow down. Biologists attribute this to setting conservation targets without considering scientific recommendations. Practitioners on the other hand claim scientific recommendations to ignore socioeconomic costs and therefore are unrealistic. In the United States, protected areas primarily include public lands but conservation easements have become increasingly more popular. However, the effectiveness of conservation easements have been debatable and has garnered much discussion. Three related issues in land conservation planning …

Shedding Light On Gis: A 3d Immersive Approach To Urban Lightscape Integration Into Gis, Andrew Kaufman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Geographic Information Systems (GIS) have the ability to map, model, and analyze real world data and phenomena, and yet visibility and lighting conditions are rarely considered or researched in Geographic Information Science (GISci). Lighting technologies have been created and implemented to overcome the darkness of night and other issues of visibility, and in no place is that more evident than urban areas. Though not researched heavily in GIS, it is now possible to model and analyze lighting of the built environment using GIS, 3D modeling and rendering software. This thesis explores the night time urban lightscape, its spatial aspects and …
