Quantifying the Unproductive Water Lost as Evaporation from Different Irrigation Designs by Analysis of the Soil Stable Water Isotope Compositions

Creatore:

Al-Oqaili, Firas M.

Abstract:

The knowledge about the intensive agricultural irrigation is very limited, but the use of irrigation is rapidly increasing. As an outcome, the sympathetic ecosystem is accepting modern irrigation that will play an essential function in the present and future for agricultural products. My dissertation will display the modification for investigation...

Part I: Synthetic Studies toward C10-functionalized Lycopodium Alkaloids. Part II: Exploration of the Pummerer Cyclization and Its Application to the Total Syntheses of the Abietane Diterpenoids

Creatore:

Li, Xin

Abstract:

This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...

An Examination of Leadership at Leah Meyer Austin Award Winning Colleges within the Achieving the Dream National Reform Network

Creatore:

Broxson, Thomas A.

Abstract:

Background. As part of the nationwide student completion agenda, the Achieving the Dream (ATD) national reform network was established to help community colleges quickly institute sustainable change scaled to impact all students at the institution in a short period of time. Although ATD has been in existence for over a...

Optimal Experimental System Design

Creatore:

Mohseni, Seyed Alireza

Abstract:

Physical experimentation in various scientific and engineering areas continues to be a useful and often necessary approach that is applied in research, development, and for general problem solving. The experimental design process however, is iterative and often involves trial and error. Alternative designs are proposed and evaluated on cost and...

Environmental Remote Sensing with Unmanned Aircraft Systems

Creatore:

Burnett, Jonathan D.

Abstract:

Small Unmanned Aircraft Systems (sUASs) equipped with optical sensors are capableof remotely sensing landscapes and wildlife at spatial and temporal resolutions that werepreviously inaccessible due to technical and budgetary limitations. Conventional remotesensing and photogrammetric workflows can be applied to the resulting high resolution imageryto facilitate new types of scientific inquiry....

Seismic assessment of unreinforced and retrofitted masonry buildings using Applied Element Method (AEM)

Creatore:

Soti, Rajendra

Abstract:

A significant number of Unreinforced Masonry (URM) buildings exist in the Pacific Northwest region of the United States of America that is a region of high seismicity, which could be subjected to both crustal and subduction zone earthquakes. The catastrophic and brittle failures associated with URM buildings in the past...

Turbine Induced Bird and Bat Fatalities at Wind Projects : Statistical Methods for Mortality Estimation Using Road and Pad Carcass Surveys

Creatore:

Maurer, Joseph D.

Abstract:

Turbines at wind projects pose a threat to birds and bats flying at altitudes within the rotor swept area. These animals die from colliding with the turbine blades. Estimating mortality, or the total number of bird or bat fatalities at a wind project, is critical to understanding environmental impacts of...

Classifying polycyclic aromatic hydrocarbon bioactivities using phenotypic screening and transcriptomics in the developmental zebrafish model

Creatore:

Geier, Mitra Celestine

Abstract:

Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants that occur in complex mixtures. These environmental mixtures can consist of both parent PAHs and their derivatives. Several parent PAHs are known or suspected mutagens and/or carcinogens, and a handful of PAH derivatives are known to be more potent mutagens and/or carcinogens...

New Graphite Intercalation Chemistry with Ethers and Amines

Creatore:

Zhang, Hanyang

Abstract:

Novel donor-typed ternary graphite intercalation compounds (GICs) are synthesized and characterized containing (1) pyrrolidinium cations with DMSO co-intercalates; (2) alkali metal cations with crown ether co-intercalates; and (3) alkali metal cations with polyethylene glycol co-intercalates. Structural and compositional data are obtained for the stable products. A new ether-amine co-intercalate exchange...

The Experiences of Students Who Complete in a Successful Distance Learning Course

Creatore:

Smith, Steve

Abstract:

Background: Prior research has shown that distance learning courses have higher failure rates at community colleges then equivalent face-to-face to courses. There are a few programs and courses, however, that consistently achieve completion rates as high as or higher than their equivalent face-to-face courses. The research to date has not...
