Fertigation Of Vegetables In Western Australia, J Burt

Bulletins 4000 -

Fertigation is the technique of using soluble fertilisers to supply essential nutrients to vegetables through sprinkler or trickle irrigation systems, or by means of a boom spray. It is ideally suited to most horticultural areas in Western Australia, especially the sandy soils of the Swan Coastal Plain that have a poor capacity to retain nutrients.

Before and after planting, nutrients are often applied to vegetables on soils of the Swan Coastal Plain by applications of poultry manure* or solid fertilisers. After planting, fertigation is a safe and effective method of applying top-dressings of nutrients to crops, especially after the rows …

Achieving Equality, Balance, And Democracy: Racial Redistricting Throughout The Civil Rights Era To The Present, Michael Nelson Bailey

Honors Theses

Redistricting is inherently invidious and when coupled with racial considerations, the stakes become much higher. Legislative representation is at the core of the governmental process in the United States. Any changes to this process affect every citizen and their influence in our government and electoral system. This paper approaches this topic from a philosophical standpoint, evaluating the theories and ideas of the Constitution, the Supreme Court, and constitutional scholars. The issue is so complex and divisive that a full understanding of the controlling forces at work is a difficult concept to grasp. In this research the Voting Rights Act and …

Gore Wars, Alex Kozinski

Michigan Law Review

Unless you've been frozen in carbonite or are hopelessly gullible, it must have occurred to you at some point during the last three decades that environmental activists are exaggerating just a bit when they claim that, unless we dramatically change our way of life, we'll soon see the end of civilization as we know it. I'm not sure when these doomsday predictions got started - probably they go back to Malthus and beyond - but I first became aware of environmental Jeremiadism in college in the early 1970s, when tout-le-monde were reading a little book called The Limits to Growth. …

Using Benford's Law To Detect Fraud In The Insurance Industry, Meredith Maher, Michael D. Akers

Accounting Faculty Research and Publications

Benford's Law is the mathematical phenomena that states that the first digits or left most digits in a list of numbers will occur with an expected logarithmic frequency. While this method has been used in industries such as oil and gas and manufacturing to identify fraudulent activity, it has not been applied to the health insurance industry. Since health insurance companies process a large number of claims each year and these claims are susceptible to fraud, the use of this method in this industry is appropriate. This paper examines the application of Benford's Law to four health insurance companies located …

Stable Isotopes Of Carbon As An Invaluable Stratigraphic Tool: An Example From The Cambrian Of The Northern Appalachians, Usa, Bosiljka Glumac, Malkah L. Spivak-Birndorf

Geosciences: Faculty Publications

This study illustrates the usefulness of carbon isotopes in stratigraphic interpretations of poorly fossiliferous strata beyond the resolution possible by biostratigraphy. The Upper Cambrian strata of the lower Gorge Formation in northwestern Vermont have been interpreted as highly condensed continental-slope deposits with a hiatus bracketed by the trilobite fauna of the Dunderbergia zone (Steptoean) and the Saukia zone (upper Sunwaptan). This interpretation was based on information from two thin fossiliferous intervals, the occurrence of one of them being unconfirmed in a recent study. Carbon isotopes provide a means for testing this interpretation because marine carbonate rocks deposited during the Steptoean …

Cosmology With Negative Potentials, Gary Felder, Andrei Frolov, Lev Kofman, Andrei Linde

Physics: Faculty Publications

We investigate cosmological evolution in models where the effective potential V(f) may become negative for some values of the field f. Phase portraits of such theories in the space of variables (f,f˙ ,H) have several qualitatively new features as compared with phase portraits in the theories with V(f).0. Cosmological evolution in models with potentials with a ‘‘stable’’ minimum at V(f),0 is similar in some respects to the evolution in models with potentials unbounded from below. Instead of reaching an AdS regime dominated by the negative vacuum energy, the universe reaches a turning point where its energy density vanishes, and then …

Summarizing Concepts About Teacher Education, Learning And Neuroscience, Terry Armstrong, Teresa J. Kennedy, Porter Coggins

Northwest Journal of Teacher Education

Despite on-going reform. teacher education today is virtually unchanged from models used in the 1920s. The achievements of the past century however have been remarkable in every way. Neuroscience records and the human genome project hold the prospect of truly expanded conceptualizations for teacher educators. This article summarizes concepts relating to the human cerebrum that speak to individual uniqueness derived from neuroscience research of the past several decades. Five areas of investigation are noted that could provide the theoretical underpinning for teacher education collaboration with neuroscientists. Neuroscience theorists are identified in anticipation that their work may provide insights to teacher …

Noise Control And Speech Intelligibility Improvement Of A Toll Plaza, Luc Mongeau, Robert J. Bernhard, Jeffery P. Feist

JTRP Technical Reports

Vehicular toll roads are one component of many municipal transportation systems. Open communication windows, often used in tollbooths, facilitate essential communication and monetary transactions. However, the vehicle noise generated outside the booth is easily transmitted into the booth via the open window. Personnel working at toll collection plazas are exposed to extended, continuous traffic noise. Sustained noise levels of this nature may cause hearing loss, induce fatigue or stress, and reduce worker productivity. The annoyance and discomfort related to continuous noise exposure may create an unpleasant working condition and may affect the hospitality of the tollbooth operators and their attitude …

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 1: Performance Parameters And Related Procedure For Concrete Bridge Superstructures, J. A. Ramirez, Jhon Paul Smith

JTRP Technical Reports

In Volume 1 of the final report, the identification of performance levels and parameters, and the development of acceptance criteria, have been addressed. Emphasis has been placed on the development of a methodology for a Performance Related Specification, PRS, for concrete bridge superstructures. The implementation of the methodology, presented in the form of a user-friendly computer program, is project specific. It requires the mean and standard deviation (or definition of a probability distribution) of the input parameters for the performance predictive models. This is done for both the as-designed condition and the as-built condition of the structure. The contractor is …

Slab-Geometry Molecular Dynamics Simulations: Development And Application To Calculation Of Activity Coefficients, Interfacial Electrochemistry, And Ion Channel Transport, Paul S. Crozier

Theses and Dissertations

Methods of slab-geometry molecular dynamics computer simulation were tested, compared, and applied to the prediction of activity coefficients, interfacial electrochemistry characterization, and ion transport through a model biological channel-membrane structure. The charged-sheets, 2-D Ewald, corrected 3-D Ewald, and corrected particle-particle-particle-mesh (P3M) methods were compared for efficiency and applicability to slab-geometry electrolyte systems with discrete water molecules. The P3M method was preferred for long-range force calculation in the problems of interest and was used throughout.

The osmotic molecular dynamics method (OMD) was applied to the prediction of liquid mixture activity coefficients for six binary systems: methanol/n-hexane, n-hexane/n-pentane, methanol/water, chloroform/acetone, n-hexane/chloroform, methanol/ …

Exploring The Limits Of The Dipole Approximation With Angle-Resolved Electron Time-Of-Flight Spectrometry, Sierra Laidman, Monica Pangilinan, Renaud Guillemin, Sung Woo Yu, Gunnar Ohrwall, Dennis W. Lindle, Oliver Hemmers

Environmental Studies Faculty Publications

Understanding the electronic structure of atoms and molecules is fundamental in determining their basic properties as well as the interactions that occur with different particles such as light. One such interaction is single photoionization; a process in which a photon collides with an atom or molecule and an electron with a certain kinetic energy is emitted, leaving behind a residual ion. Theoretical models of electronic structures use the dipole approximation to simplify x-ray interactions by assuming that the electromagnetic field of the radiation, expressed as a Taylor-series expansion, can be simplified by using only the first term. It has been …

A New Approach To Evaluate Fracture Strength Of Uv-Liga Fabricated Nickel Specimens, Catherine Oropeza

LSU Master's Theses

One of the major difficulties faced by MEMS researchers today is the lack of data regarding properties of electroplated metals or alloys at micro-levels as those produced by the LIGA and LIGA related process. These mechanical properties are not well known and they cannot be extrapolated from macro-scale data without experimental verification. This lack of technical information about microscale physical properties has affected the consistency and reliability of batch-fabricated components and leads to very low rates of successful fabrication. Therefore, this material issue is of vital importance to the development of LIGA technology and to its industrial applications. This thesis …

Determination Of Mass Excavation Haul Distance And Direction By Linear Optimization, Donald Scott Myers

UNLV Retrospective Theses & Dissertations

This thesis develops a two-dimensional grid system for the determination of the haul distance and direction to haul the soil on a mass excavation project using linear optimization programming methodology. The system generates a mathematical solution for the minimum haul distance and the direction in which to haul the soil for each unit of the program grid when formulated with the proper input. The necessary inputs are the calculated cut and fill quantities for each cell of an X-Y coordinate grid system. The mathematical outputs from the cut and fill inputs are converted into a vector drawing indicating the quantity …

The Effect Of Mechanical Vibration On Acute Power Output In The Bench Press, Brach John Poston

UNLV Retrospective Theses & Dissertations

The purpose of this study was to investigate the effect of mechanical vibration on acute power output in the bench press. A total of 10 male subjects performed 3 sets of 3 reps of bench presses using a load equal to 70% one repetition maximum (1RM) on two occasions separated by 3 days. One occasion served as the experimental (vibration) condition while the other occasion served as the control (non-vibration) condition. The conditions differed due to a 30 second vibration stimulation period between bench press sets 2 and 3 in the experimental condition. The control condition incorporated a 30 second …

Examining The Cost-Outcome Relationship Of A Fortified Class-Size Reduction Program, Derick M. Kiger

Mid-Western Educational Researcher

Class-size reduction initiatives have been criticized for producing modest achievement gains for the resources they consume. Wisconsin’s Student Achievement Guarantee in Education (SAGE) was designed to amplify the achievement benefits of smaller classes by requiring complementary changes in the teaching and learning environment and accountability for results. This study examined SAGE in an urban school district. The achievement benefits realized by the evaluand were marginalized by high per-student costs and similar performance of comparison groups on a state-mandated reading test. Suggestions for improving the cost-outcome relationship were presented.
