Effects Of Rain And Simulated Rain On Deoxynivalenol Levels In Grain And Chaff Of Winter Wheat With Fusarium Head Blight, Manoj Kumar Pun Dec 2013

Effects Of Rain And Simulated Rain On Deoxynivalenol Levels In Grain And Chaff Of Winter Wheat With Fusarium Head Blight, Manoj Kumar Pun

Graduate Theses and Dissertations

Wheat grain affected by Fusarium head blight (FHB) contains the mycotoxin deoxynivalenol (DON) that is harmful to humans and animals. Reducing the amount of DON in grain is the goal of management practices for FHB so it is important to understand the factors affecting DON in grain. Some studies on the effects of late-season moisture found increases in DON while others found decreases due to leaching. The objectives of this study were to determine effects of late-season rain and misting on DON concentration in wheat spike tissues and to quantify the amount of DON leached from spikes. Field experiments were …

Application Of Image Processing And Finite Element Analysis In Modeling Chloride Diffusion In Concrete, Arash Razmjoo Dec 2013

Application Of Image Processing And Finite Element Analysis In Modeling Chloride Diffusion In Concrete, Arash Razmjoo

All Dissertations

Utilizing numerical simulation models to predict the long-term mechanical and transport behavior of concrete structures is becoming increasingly popular. The majority of these models have been developed using laboratory test data that consider concrete as a homogeneous material with spherical aggregates. These models could not be a represented of real concrete because it has no primitive shaped aggregate besides that the porosity size and distribution varies from point to point. In this study a novel method for more accurate prediction of the chloride diffusion in concrete was developed. A general framework of the quantitative computed tomography (QCT) and finite element …

Finding The Best Function: A Way To Explain Calculus Of Variations To Engineering And Science Students, Olga Kosheleva, Vladik Kreinovich Dec 2013

Finding The Best Function: A Way To Explain Calculus Of Variations To Engineering And Science Students, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical problems, we need to find the most appropriate function: e.g., we need to find a control strategy u(t) that leads to the best performance of a system, we need to find the shape of the car which leads to the smallest energy losses, etc. Optimization over an unknown function can be described by the known Euler-Lagrange equations. The traditional way of deriving Euler-Lagrange equations when explaining them to the engineering and science students is, however, somewhat over-complicated. We provide a new, simpler way to deriving these equations, a way in which we directly use the fact that …

There have been previous hints that the transiting planet WASP-3b is accompanied by a second planet in a nearby orbit, based on small deviations from strict periodicity of the observed transits. Here we present 17 precise radial velocity (RV) measurements and 32 transit light curves that were acquired between 2009 and 2011. These data were used to refine the parameters of the host star and transiting planet. This has resulted in reduced uncertainties for the radii and masses of the star and planet. The RV data and the transit times show no evidence for an additional planet in the system. …

The Effects Of Microstructure On The Mechanical Properties Of Hard Transition Metal Silicon Nitride Nanocomposite Coatings, Jessica Mooney Dec 2013

The Effects Of Microstructure On The Mechanical Properties Of Hard Transition Metal Silicon Nitride Nanocomposite Coatings, Jessica Mooney

Material Science and Engineering Dissertations - Archive

In this body of work, the examination of two different transition metal silicon nitride (MeSiN) systems using two different methods of physical vapor deposition (PVD) allowed for the development of a detailed understanding between the processing conditions, the micro-scale and nano-scale morphology, and the mechanical properties of the as-deposited thin film nanocomposite coatings. TiSiN coatings processed using the high-energy Arc deposition technique had hardness values of up to 33.6 GPa, and a previously unidentified (TiSi)N FCC crystalline phase, likely present due to the amounts of energy employed during coating processing, was discovered via intensive low angle X-Ray diffraction (XRD) and …

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips Dec 2013

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips

Research Collection School Of Economics

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized regression techniques. We focus on linear models where the slope parameters are heterogeneous across groups but homogenous within a group and the group membership is unknown. Two approaches are considered -- penalized least squares (PLS) for models without endogenous regressors, and penalized GMM (PGMM) for models with endogeneity. In both cases we develop a new variant of Lasso called classifier-Lasso (C-Lasso) that serves to shrink individual coefficients to the unknown group-specific coefficients. C-Lasso achieves simultaneous classification and consistent estimation in a single …

Between The Posts: Research On The Cap And Top Rail To Guardrail Post Connection, Blake Buckner

Landscape Architecture Undergraduate Honors Theses

Between 2003 and 2007, an estimated 11,120 Americans went to the emergency room as a direct result of a structural failure or collapse of wood deck railings. This is an average of 2,224 people each year. Furthermore, estimates show there are over 40 million decks in the United States and about half of these are more than fifteen years old, which is past their expected lifespan (Legacy Services, 2012). Decks are exterior structures susceptible to the elements that degrade over time, making the need for proper, safe construction techniques even more important. The safety of unsuspecting people who use decks …

On The Biophysics And Kinetics Of Toehold-Mediated Dna Strand Displacement, Bernard Yurke Dec 2013

On The Biophysics And Kinetics Of Toehold-Mediated Dna Strand Displacement, Bernard Yurke

Electrical and Computer Engineering Faculty Publications and Presentations

Dynamic DNA nanotechnology often uses toehold-mediated strand displacement for controlling reaction kinetics. Although the dependence of strand displacement kinetics on toehold length has been experimentally characterized and phenomenologically modeled, detailed biophysical understanding has remained elusive. Here, we study strand displacement at multiple levels of detail, using an intuitive model of a random walk on a 1D energy landscape, a secondary structure kinetics model with single base-pair steps and a coarse-grained molecular model that incorporates 3D geometric and steric effects. Further, we experimentally investigate the thermodynamics of three-way branch migration. Two factors explain the dependence of strand displacement kinetics on toehold …

The True Value Of A Law Degree, Or, Why Did Thurgood Marshall Go To Law School?, R. Lawrence Dessem, Gregory M. Stein Dec 2013

The True Value Of A Law Degree, Or, Why Did Thurgood Marshall Go To Law School?, R. Lawrence Dessem, Gregory M. Stein

Faculty Publications

There has been vigorous debate in recent months over whether a law degree is a worthwhile investment. Much of this discussion has focused on whether the economic costs of obtaining a degree pay off over a lawyer’s career. This conversation has largely overlooked the many non-economic benefits of a law degree. In this essay, we seek to re-introduce several non-economic factors back into this important dialogue. We suggest that prospective law school applicants would be wise to consider these non-economic factors in addition to economic ones.

Nanoindentation Of Piezoelectric Materials, Guang Cheng Dec 2013

Nanoindentation Of Piezoelectric Materials, Guang Cheng

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Piezoelectric materials, with their unique electromechanical coupling characteristics, have found widespread use in many applications as sensors and actuators. With a continuing demand for macroscale piezoelectric devices with better performance characteristics, numerous efforts have been made to synthesize " bulk" monolithic and composite piezoelectric materials with better properties. More recently, within the context of microscale devices such as smart MEMS, self-powered sensors, microbatteries, and energy harvesting devices, there is a growing interest in developing " thin-film" piezoelectric materials. While, advances in microfabrication technology have greatly helped the synthesis and fabrication of piezoelectric thin films and structures, there is a continuing …

Physical And Chemical Modifications Of Surface Properties Lead To Alterations In Osteoblast Behavior, Kathryn Elizabeth Dorst Dec 2013

Physical And Chemical Modifications Of Surface Properties Lead To Alterations In Osteoblast Behavior, Kathryn Elizabeth Dorst

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Proper formation of the bone extracellular matrix (ECM), or osteoid, depends on the surface properties of pre-existing tissue and the aqueous chemical environment. Both of these factors greatly influence osteoblast migration, cytoskeletal organization, and calcium nodule production, important aspects when considering the biocompatibility of bone implants. By perturbing the physical and/or chemical micro-environment, it may be possible to elucidate effects on cellular function. To examine these factors, murine pre-osteoblasts (MC3T3-E1 subclones 4 and 24) were seeded on polydimethylsiloxane (PDMS) substrates containing " wide" micro-patterned ridges (20 μ m width, 30 μ m pitch, & 2 μ m height), " narrow" …
