Economic Impacts Of The Kentucky Green Industry [2015], Dewayne L. Ingram, Alan Hodges

Agriculture and Natural Resources Publications

The green industry, comprised of firms engaged in the production and use of landscape and floral crops and related supplies and equipment and the design, construction, and maintenance of landscapes, has a significant impact on Kentucky’s economy. Green-industry enterprise owners, managers, and employees should be aware of their economic impacts, and policy makers and other state leaders need to know the importance of this industry as potential laws, regulations and resource allocations are considered. This publication is intended to provide a brief summary of the 2013 economic impacts of the green industry in Kentucky.

Distinguishing Softwoods From Hardwoods, Terry Conners

Agriculture and Natural Resources Publications

Softwood and hardwood trees are made up of different types of cells. With just a little magnification, it’s easy to see that softwood growth rings look different from hardwood growth rings. Additionally, growth rings don’t look the same for all of the trees, and the growth ring appearance is one of the things we will look at to identify wood.

Characteristics Of Kentucky’S Nursery And Greenhouse Industries [2015], Dewayne L. Ingram, Winston Dunwell, Alan Hodges

Agriculture and Natural Resources Publications

The nursery and greenhouse industry in Kentucky is diverse and contributes significantly to the local and state economy. This industry represents the largest segment of Kentucky’s sales of horticultural products and is comprised almost completely of farm families. Nursery and greenhouse operations have historically been characterized as separate production systems and crops. However, today primary nurseries may also have greenhouses and/or produce herbaceous perennials and annuals to satisfy their customer base. On the other hand, many primary greenhouse firms that once grew mostly annuals and potted flowering crops have expanded their product line to include herbaceous perennials, often finished in …

Introduction To Wood Structure And Characteristics, Terry Conners

Agriculture and Natural Resources Publications

Wood is identified using the features and tools that are appropriate to the size of the sample. Large timbers are identified by looking at the color, the appearance of the end and side grain, whether a saw cuts cleanly or leaves lots of splinters behind, whether the wood has straight or curly drying cracks, and so forth. The hardness and density provide valuable information as well. For smaller pieces of wood, it’s more practical to look directly at the wood cells with a 10X hand lens (also called a loupe). Different species have different characteristics and combinations of these features …

Grain Patterns And Growth Rings, Terry Conners

Agriculture and Natural Resources Publications

The preceding article, "Identifying Wood–A Primer for Everyone, Part 3: Distinguishing Softwoods from Hardwoods" (FOR-125), described how to distinguish softwoods from hardwoods, and that’s the first step in identifying an unknown piece of wood. At this point, additional terminology is necessary to further distinguish between species, and I'll begin by talking about the different sides of a hypothetical piece of wood. Frequently you need to be able to observe wood cells from a particular perspective, and you will need to know where to look for different features on your sample. It’s also very helpful to develop a kind of “visual …

The First Separation Of Softwood Species, Terry Conners

Agriculture and Natural Resources Publications

Just making the separation between softwoods and hardwoods doesn’t help much in identifying wood species; that would be sort of like identifying children by their hair color. Let’s look at the next level of wood features that you need to be able to recognize.

First Steps In Identifying Wood, Terry Conners

Agriculture and Natural Resources Publications

Wood samples need to be identified for all sorts of reasons, and they come in all shapes, sizes and conditions. I’ve received samples that were sound, samples that were waterlogged, samples that were rotted or otherwise degraded, painted samples, furniture samples, even samples containing wood preservatives. Most of the samples I receive have a North American origin, but I also receive pieces from art museums and antique dealers that can originate from just about anywhere. This sometimes means that identifying the sample by a common name alone doesn’t provide enough information.

Impact Of Sleep And Circadian Disruption On Energy Balance And Diabetes: A Summary Of Workshop Discussions, Deanna M. Arble, Joseph Bass, Cecilia Diniz Behn, Matthew P. Butler, Etienne Challet, Charles Czeisler, Christopher M. Depner, Joel Elmquist, Paul Franken, Michael A. Grandner, Erin C. Hanlon, Alex C. Keene, Michael J. Joyner, Ilia Karatsoreos, Philip A. Kern, Samuel Klein, Christopher J. Morris, Allan I. Pack, Satchidananda Panda, Louis J. Ptacek, Naresh M. Punjabi, Paolo Sassone-Corsi, Frank A. Scheer, Richa Saxena, Elizabeth R. Seaquest, Matthew S. Thimgan, Eve Van Cauter, Kenneth P. Wright

Clinical and Translational Science Faculty Publications

A workshop was held at the National Institute for Diabetes and Digestive and Kidney Diseases with a focus on the impact of sleep and circadian disruption on energy balance and diabetes. The workshop identified a number of key principles for research in this area and a number of specific opportunities. Studies in this area would be facilitated by active collaboration between investigators in sleep/circadian research and investigators in metabolism/diabetes. There is a need to translate the elegant findings from basic research into improving the metabolic health of the American public. There is also a need for investigators studying the impact …

How Does The Connectivity Of Open-Framework Conglomerates Within Multi-Scale Hierarchical Fluvial Architecture Affect Oil-Sweep Efficiency In Waterflooding?, Naum I. Gershenzon, Mohamad Reza Soltanian, Robert W. Ritzi, David F. Dominic, Don Keefer, Eric Shaffer, Brynne Storsved

Physics Faculty Publications

Understanding multi-phase fluid flow and transport processes within aquifers, candidate reservoirs for CO2 sequestration, and petroleum reservoirs requires understanding a diverse set of geologic properties of the aquifer or reservoir, over a wide range of spatial and temporal scales. We focus on multiphase flow dynamics with wetting (e.g., water) and non-wetting (e.g., gas or oil) fluids, with one invading another.

Adsorption Equilibrium Of Carbon Dioxide On Ammonia-Modified Activated Carbon, M.S. Shafeeyan, W.M.A.W. Daud, A. Shamiri, N. Aghamohammadi

Research Publications (2011 to 2015)

The equilibrium adsorption isotherms of carbon dioxide on a commercial granular activated carbon (GAC) and an ammonia-modified GAC (OXA-GAC) were measured using a static volumetric method. CO2 adsorption measurements were performed at three different temperatures (303, 318, and 333 K), and pressures up to 1 atm. The obtained equilibrium data were fitted to the Freundlich, Sips, and Toth isotherms using a semi-empirical approach to differentiate the contributions of physical and chemical adsorption to the total CO2 uptake. The isotherm parameters were determined independently for each mechanism by non-linear regression. To evaluate the adequacy of the fit of the isotherm models, …

Fluid Uptake Of The Goddard Shale In Southeastern Oklahoma, Usa, Paul Huggins

Earth & Environmental Sciences Theses - Archive

The South Central Oklahoma Oil Province is the current play for the Goddard shale and is also the main field for the underlying Woodford Formation. As of September 2015, an estimated 40 wells have been drilled to evaluate and produce the Goddard shale in the southeastern portion of the Anadarko Basin. With companies reporting initial production rates ranging from 1,000 boe/d to nearly 2,000 boe/d and 30 day reports averaging around 800 boe/d, the amount of recovery from this tight shale reservoir has exceptional potential. Continental Resources Inc. estimates a gross recovery of 940,000 boe per lateral well. Understanding the …

An Investigation Into The Efficacy Of Mind Maps In Software Development Among Individuals And Pairs, Philip L. Bond

Information Systems & Operations Management Theses - Archive

Software development is a cognitively demanding endeavor in which the creation and exchange of knowledge is paramount. Collaborative development, particularly pair programming, has been more advocated and adopted recently by practitioners. However, empirical studies have not categorically established the efficacy of pairs vis-à-vis individuals in software design contexts. In fact, recent findings suggest that pairs seldom outperform best individuals although they tend to do better than average individuals. Group losses arising from lack of coordination and/or communication could be a plausible explanation for this. The extant literature suggests that Mind Maps have the potential to graphically capture concepts and their …

Uptake Of Plutonium On A Novel Thin Film For Use In Spectrometry, William Locklair

All Theses

Trace elemental and isotopic analysis of actinides via Thermal Ionization Mass Spectrometry (TIMS) is often difficult and time consuming due to intensive sample preparation. Polymer thin films show strong potential for rapid concentration of radionuclides from solution that may prove as suitable substrates for TIMS analyses. In this work, a polymer thin film (~180 nm) was coated onto a silicon substrate and utilized for rapid radioanalytical analysis. The polymer is composed of poly(vinyl benzyl chloride) functionalized with triethyl amine (TEA) to produce an anion-exchange site for concentrating anionic actinide complexes (i.e. PuCl62-, Pu(NO3)62-) from solution. In addition, selectively functionalizing “spots” …

Using Frequent, Unannounced, Focused, And Short Classroom Observations To Support Classroom Instruction, Lawrence T. Cook

Dissertations

This paper examines the need to do more frequent, short (10- to 15-minute), unannounced, and focused classroom observations to support classroom instruction. Currently, the state requires at least one to three classroom observations per teacher; the number of observations is based on tenured and rating status. Classroom observations consist of at least a 15- to 30-minute pre-observation, a 30- to 60-minute observation, and a 30- to 45-minute postobservation. The diagnostic framework of Wagner, Kegan, Lahey, Lemons, Garnier, Helsing, Howell, and Rasmussen’s (2006) systemic change plan was used. The process looked at current (As-Is) and future (To-Be) status of an organization …

Analyzing And Assessing The Experience Of Traveling By Public Transport, Martin Schiefelbusch

Journal of Public Transportation

The experience of traveling (as an aggregate of sensory impressions in relation to social and psychological needs) has so far rarely been considered as a factor influencing travel and modal choice. This paper proposes a practical way to disaggregate the “travel experience” into its separate components and suggests a procedure to assess the “experiential qualities” of (mainly public) transport services. This assessment allows planners to compare different user groups’ expectations as well as the provider’s strategic objectives. The procedure then is discussed in relation to several recent strands of transport/mobility research that are approaching the travel experience from different points …

Pre Kindergarten Students Increased Letter Recognition Ability Through The Use Of Educational Apps On Tablets For Classroom Instruction, Corrie C. Giugni

Dissertations, Masters Theses, Capstones, and Culminating Projects

Preschool students are preparing for kindergarten. The kindergarten curriculum is demanding. Students are expected to enter elementary school knowing many aspects related to language arts. The problem at the preschool level is that children need to master letter recognition and letter sounds in order to prepare them to learn how to read. The literature reveals that using technology before they enter kindergarten can be beneficial in developing students emergent literacy skills (Beschorner & Huchison, 2013).

It is important for teachers to meet the needs of all of their students. Using electronic tablets in the classroom is a tool that can …

Building Depth Of Understanding Of The Concept Of Number Sense And Algebra In Students Grades 7 And 8, Catherine Janes

Dissertations, Masters Theses, Capstones, and Culminating Projects

Mathematics instruction offers both challenges and rewards to students. Teachers tend to focus on transmission of knowledge. Student creativity and problem-solving skills are not typically activated with common teaching practices. When students are engaged in mathematics they are recognizing patterns, making connections on their own, coming up with creative solutions, and discussing mathematical ideas with peers and adults. The purpose of this study was to identify, employ, and evaluate strategies that engage students in these practices and assist them in developing a deep understanding of mathematics concepts such as number sense and algebra.

The review of the literature began with …

On The Local Isometric Embedding In R^3 Of Surfaces With Zero Sets Of Gaussian Curvature Forming Cusp Domains, Tsung-Yin Lin

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

We study the problem of isometrically embedding a two-dimensional Riemannian manifold into Euclidean three-space. It is shown that if the Gaussian curvature vanishes to finite order and its zero set consists of two smooth curves tangent at a point, then local sufficiently smooth isometric embeddings exist. | 64 pages

A Sharp Boundary Model For Electrocardiac Simulations, Shuai Xue

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

We present a sharp boundary electrocardiac simulation model based on the finite volume embedded boundary method for the solution of voltage dynamics in irregular domains with anisotropy and a high degree of anatomical detail. This method is second order accurate uniformly up to boundaries and is able to resolve small features without the use of fine meshes. This capability is necessary to enable the repeated simulations required for future verification and validation (V&V) and uncertainty quantification (UQ) studies of defibrillation, where fine-scale heterogeneities, such as those formed by small blood vessels play an important role and require resolution. | 85 …

Convergence Of Manifolds And Metric Spaces With Boundary, Raquel Del Carmen Perales Perales Aguilar

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

We study sequences of oriented Riemannian manifolds with boundary and, more generally, integral current spaces and metric spaces with boundary. We prove theorems demonstrating when the Gromov-Hausdorff [GH] and Sormani-Wenger Intrinsic Flat [SWIF] limits of sequences of such metric spaces agree. Thus in particular the limit spaces are countably $\mathcal{H}^n$ rectifiable spaces. From these theorems we derive compactness theorems for sequences of Riemannian manifolds with boundary where both the GH and SWIF limits agree. For sequences of Riemannian manifolds with boundary we only require nonnegative Ricci curvature, upper bounds on volume, noncollapsing conditions on the interior of the manifold and …

High-Resolution Detection Of Change-Point With Low Coverage Single-Cell Sequencing Data, Huan Qi

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

Advances in next-generation sequencing technologies are revolutionizing our ability to detect copy number variations (CNVs). Single-cell sequencing technology allows for the genome wide copy number analysis within a single nucleus which is isolated form mixed population of cells. It can avoid the disadvantage of genomic differences in complex mixtures of cells. Many statistical methods and tools have been developed for CNVs detection using high-throughput sequencing data, but most methods are not designed for low-coverage sequencing data. In this article, we present a new Bayesian based change-point Model which has never been used for CNVs detection before and propose two similarity …

On The Route To Chaos For Two-Dimensional Modestly Area-Contracting Analytic Maps, Ying Chi

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

It has long been conjectured that the two-dimensional dissipative maps, like their one-dimensional counterparts, experience the period-doubling cascade to chaos. In [CEK], Collet, Eckmann and Koch proved this conjecture for highly dissipative families. In this dissertation, we introduce the notion of nested systems that generalizes Henon maps, and construct two operators acting on the space of nested systems based on the idea of the return maps. We use the two operators to show that if a dissipative nested system satisfies some apriori bounds, then they can be replaced with simpler but dynamically equivalent nested systems. We prove that the total …

Non-Adiabatic Dynamics Of Gene Regulatory Network, Cong Chen

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

Gene regulatory network is a mathematical model of gene expression and regulation in cell environment. The concept of network comes from network in math and computer science. In gene network each node is a gene that has different expression level and links between nodes represent direct regulation (activation or repression). Gene network is stochastic with intrinsic noise from biochemical reactions involved and extrinsic noise from environment. It is non-equilibrium with frequent matter/energy exchange and active entropy production. One crucial character of gene network is the involvement of multiple timescales: timescale of protein synthesis/degradation and timescale of regulation processes. Conventional studies …
