Release Of No(X) From Sunlight-Irradiated Midlatitude Snow, R E. Honrath, Matthew C. Peterson, M P. Dziobak, Jack E. Dibb, Matthew Arsenault, S A. Green

Earth Sciences

Photochemical production and release of gas-phase NO(x) (NO + NO2) from the natural snowpack at a remote site in northern Michigan were investigated during the Snow Nitrogen and Oxidants in Winter study in January 1999. Snow was collected in an open 34 L chamber, which was then sealed with a transparent Teflon cover and used as an outdoor flow and reaction chamber. Significant increases in NO(x) mixing ratio were observed in synthetic and ambient air pulled through the sunlit chamber. [NO(x)] enhancements were correlated to ultraviolet sunlight intensity, reaching ~300 pptv under partially overcast midday, mid-winter conditions. These findings are …

Nonlinear Analysis Of Unsymmetric Laminates Under Cylindrical Bending, Eun Seon Park

Master's Theses - Daytona Beach

Nonlinear analysis of unsymmetric composite long, narrow laminates under cylindrical bending is studied. The nonlinear governing equations are obtained to analyze the cylindrical bending of arbitrary laminates. The von-Karman type geometrical nonlinearity is incorporated in the governing equation. The shear effect between lamina is further considered in the governing equation. The solution is obtained for different boundary conditions. The results of arbitrary angle-plies are discussed. Unidirectional prepreg graphite-epoxy is considered for numerical results.

An Analysis Of The Influence Of Age And Ionizing Radiation On Cognitive Performance, Elizabeth L. Gerhardt

Master's Theses - Daytona Beach

This thesis was designed to study whether age has a significant effect on cognitive test results among persons exposed to ionizing radiation. The data for this investigation came from the fourth year of a 1995-98 longitudinal study of subjects exposed to radiation from the 1986 Chernobyl, Ukraine, nuclear power plant accident. Accuracy and efficiency scores from four cognitive tests taken by 84 Ukrainian volunteers were divided into two age groups and three radiation dosage groups for analysis. The results of this study found that decrements in human performance on tasks involving spatial processing increase with age in persons who have …

The Application And Performance Of A Generic Task Routine Decision Making Algorithm To Recipe Selection In Meal Planning, Michelle M. Cox

Theses and Dissertations - UTB/UTPA

A nutritional meal planning system was implemented to test the effectiveness of a previously developed routine decision making algorithm. The combinatorics involved in ordering recipes in all possible combinations to produce variability in a meal plan and provide sufficient nutrition is conceptually intensive. Meal planning involves selection of food to eat to fulfill a person's nutritional and personal preferences. This thesis demonstrates meal planning as a decision making problem and demonstrates the utility of the routine decision making algorithm by solving this problem. Generic Tasks, identified through artificial intelligence research, provides the basis for this algorithm. It uses user preferences …

Economic Sanctions: Their Ineffectiveness At Attaining Their Stated Foreign Policy Goals With Specific Reference To The Cuban Case, Harold Lee Ingram

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

International economic sanctions are not singularly modem phenomena. In ancient Greece, Pericles of Athens enacted the Megerian Decree in 432 BC in response to hostile acts taken against it by neighboring Megera. Later, during the American Revolutionary War, Thomas Jefferson encouraged the use of sanctions as an effective tool of coercive foreign policy to be used against the colonists' enemies. Since then, following the historical precedence of economic acts like the Megerian Decree, economic sanctions have continued to be used as tools of coercive diplomatic policy. For example, following World War I, President Woodrow Wilson encouraged the use of economic …

Swapping Space For Time And Unfair Tests Of Ecological Models, Andrew J. Tyre, Brigitte Tenhumberg, Michael A. Mccarthy, Hugh P. Possingham

School of Biological Sciences: Faculty Publications

Testing ecological models for management is an increasingly important part of the maturation of ecology as an applied science. Consequently, we need to work at applying fair tests of models with adequate data. We demonstrate that a recent test of a discrete time, stochastic model was biased towards falsifying the predictions. If the model was a perfect description of reality, the test falsified the predictions 84% of the time. We introduce an alternative testing procedure for stochastic models, and show that it falsifies the predictions only 5% of the time when the model is a perfect description of reality. The …

Hidden Mechanisms Generate Negative Feedbacks In A Stochastic Model: A Comment On Murray, Andrew J. Tyre, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

The debate between density-dependent and densityindependent population regulation is one of the oldest and most vociferous in ecology. Australian ecologists participated from the beginning (Nicholson 1933; Andrewartha & Birch 1954). Despite recent efforts to put the debate to rest (Turchin 1995, 1999), there appears little likelihood of either side abandoning the ramparts (Bonsall et al. 1998). Murray (2000; this issue) uses a stochastic simulation model to argue that a significant statistical relationship between birth rate and population size (i.e. density dependence) can arise in the absence of negative feedbacks of population size on fecundity. In this comment we demonstrate that …

Nutrient Absorption And Utilization By Wing And Flight Muscle Morphs Of The Cricket Gryllus Firmus: Implications For The Trade-Off Between Flight Capability And Early Reproduction, Anthony J. Zera, Tammy Brink

Anthony Zera Publications

Absorption efficiency (AD, approximate digestibility, assimilation efficiency) of various macronutrients and conversion of absorbed nutrients to biomass (ECD) were compared among the two types of flightless morph and the flight-capable morph of the cricket, Gryllus firmus. No biologically significant phenotypic or genetic difference in AD for carbohydrate, protein or lipid was observed among morphs fed either a high-nutrient (100%) or a low-nutrient (25%) diet. Thus, previously-documented differences among adult morphs in carbohydrate and lipid content must be caused by processes other than variation in nutrient absorption by morphs during adulthood. Relative absorption efficiency of total dry mass of food …

North Atlantic Intermediate To Deep Water Circulation And Chemical Stratification During The Past 1 Myr, Benjamin P. Flower, D. W. Oppo, J. F. Mcmanus, K. A. Venz, D. A. Hodell, J. L. Cullen

Marine Science Faculty Publications

Benthic foraminiferal carbon isotope records from a suite of drill sites in the North Atlantic are used to trace variations in the relative strengths of Lower North Atlantic Deep Water (LNADW), Upper North Atlantic Deep Water (UNADW), and Southern Ocean Water (SOW) over the past 1 Myr. During glacial intervals, significant increases in intermediate-to-deep delta(13)C gradients (commonly reaching >1.2 parts per thousand) are consistent with changes in deep water circulation and associated chemical stratification. Bathymetric delta(13)C gradients covary with benthic foraminiferal delta(18)O and covary inversely with Vostok CO2, in agreement with chemical stratification as a driver of atmospheric CO2 changes. …

Growing Lavender In Western Australia, Aileen Reid

Bulletins 4000 -

Lavender oil is an essential oil, derived from plants (genus Lavendulai primarily by steam distillation of the flowers. There are several types of lavender oil. The 'true' lavender oil, and the most highly prized, comes from Lavendula augustifolia; it is primarily used in the fragrance and perfume industry. World production is about 200 tonnes per year. Spike lavender oil, derived from Lavendula latifolia, has a world production of about 150-200 tonnes per year. Lavandin oil is derived from hybrids of L. augustifolia x L. latifolia that yield much higher than L. augustifolia but the oil is lower quality, hence it …

A Study Of The Color Management Implementation On The Rgb-Based Digital Imaging Workflow: Digital Camera To Rgb Printers, Darunee Sa-Areddee

Theses

An RGB (red, green, and blue color information) workflow is used in digital photography today because a lot of the devices digital cameras, scanners, monitors, image recorders (LVT or Light Value Technology), and some types of printers are based on RGB color information. In addition, rapidly growing new media such as the Internet and CD-ROM (Compact Disc-Read-Only Memory) publishing use an RGB -based monitor as the output device. Because color is device-dependent, each device has a different method of representing color information. Each has a different range of color they can reproduce. Most of the time, the range of color, …

Photophysical Study Of Linked 1,4,7-Triazacyclonane Cr (Iii) Complexes, Weizhen Tu

Masters Theses

A series of mono and bimetallic Cr(III) complexes based on the 1,4,7- triazacyclonoane(TACN) were prepared. Complexes of the Cr(TACN)X₃ , and Cr₂(DTNE)X₆ demonstrated marked difference of photophysical properties on the nature of X. In cases where X is more easily oxidized, enhanced extinction coefficient in the ⁴A₂ ➔ ²T, absorption and larger quantum yield of emission at 77K were observed in the dimer complexes. Shorter lifetime and enhanced decay rate were also found in the dimer complexes suggests that there might exists weak coupling behavior between the two Cr(III) metal cents in the …

The Benefits Of Observational Learning On The Mathematics Achievement Of Fourth Grade Students Involved In Peer Tutoring Sessions, Trisha R. Parish

Masters Theses

Many students struggle with mathematical concepts and operations. This leads educators to search for the most effective and efficient means of improving their academic performance. The present investigation sought to determine if a triadic peer-tutoring program would increase the acquisition of basic multiplication facts for fourth grade students. Secondly, this investigation assessed the extent to which students would benefit from observational learning opportunities within the peer tutoring sessions. A multiple baseline design across two peer-tutoring triads was utilized with student performance being assessed by measuring responses to flashcard presentations and completion of three types of mathematics probes. The first type …

Teacher Performance Incentives And Student Outcomes, Randall W. Eberts, Kevin Hollenbeck, Joe Allan Stone

Upjohn Institute Working Papers

This paper reviews the evidence on the effectiveness of individual merit pay systems for teachers on student achievement, and it presents new empirical results based on a system established within a collective bargaining environment. While many merit pay systems have been established in school districts across the U.S., very little empirical evidence concerning their influence on student achievement exists. A natural experiment arose in a county in which one high school piloted a merit pay system that rewarded student retention and student evaluations of teachers while another comparable high school maintained a traditional compensation system. A difference-in-differences analysis implies that …
