The Rusty Blackbird (Euphagus carolinus) has gained notoriety in recent years as one of the fastest declining North American bird species, with a global population loss of as much as 95%. Causes of the decline are not completely understood, but the high rate of forested wetland change in the southeastern United States suggests that wintering habitat degradation may be a....

This study sought a time-efficient way to implement writing in ninth-grade Geometry. Students wrote responses to five expository writing prompts spread out over the spring semester of the 2014-2015 school year. Students first attempts were graded and returned to them along with feedback in the form of a teacher-written exemplar. Students rewrote assignments to improve t....

Three field experiments were conducted in a mango orchard in Croix-des-bouquets (Haïti) to develop an effective artisanal McPhail trap, less expensive than the commercial traps, for mass trapping Anastrepha obliqua (Macquart) and Anastrepha suspensa (Loew). A field trial conducted to evaluate the effectiveness of two newly made artisanal trap models (AT1 and AT2) with ....

The thesis examines a panel of trade flows during 2009-2013, exploring the influence of regulatory quality on the pattern of forest products imports by India from 143 partner countries. The study applies a pooled regression model followed by Generalized Least Squared (GLS) technique and a more robust Feasible Generalized Least Squared (FGLS) method of estimation with re....

Developing improved cotton cultivars depends on how cotton cultivars perform the best when under stresses. Reniform nematode is a major plant pathogen, causing 4-6% yield loss in southern United States. A variation in reproduction and pathogenicity across reniform isolates collected from Louisiana on susceptible cotton was reported. This study was conducted to determine....

Using the Method of Receptance, it is possible in general to assign 2 poles (i.e. n conjugate pairs) of an axially vibrating rod of variable cross section by sensing the state at points along the rod. Using the sensor data, closed loop feedback control gains can be calculated by solving a simple set of linear equations. The feedback gains can be applied to generate the ....

Due to their corrosion resistance, high temperature stability, high strength, and high hardness, refractory ceramic thin films and coatings have been utilized for surface engineering of mechanical components and mechanical fabrication tools. Adhesion between ceramic thin films and coatings and the substrate is of critical concern for performance and life time of coated ....

Reading instruction has historically been deemphasized for students in special education, and the limited research on this topic reveals that sight word vocabulary is most commonly taught in special education classrooms (Browder, Wakeman, Spooner, Ahlgrim-Delzell, Algozzine, 2006). However, successful reading instruction must target the five essential components: vocabu....

Suicide contagion is a real phenomenon. The stigmatization of suicide attempters, completers, survivors of suicide loss, and the idea of suicide itself is at least partly to blame for these outbreaks. Regarding suicide as an analyst, journalist, witness, responder, or bereaved family member or friend can be a devastating form of metaphorical and literal looking. Through....

We present a theoretical study of attosecond transient absorption in gases and high harmonic generation in solids. In this thesis, different features in the attosecond transient absorption laser-dressed spectrum are studied, including features near bright (dipole allowed) atomic states and features that appear approximately one or two laser photons away from the bright ....

Segmented flow can be utilized in lab-on-a-chip technologies to speed up chemical and biological analysis. Segmented flow (also known as Taylor flow or the Bretherton problem) has often been explored in circular channels, but rectangular channels are more common for microfluidics applications. To this end, pressure-driven droplet flow in a square microchannel is studied....

Iron-sulfur proteins comprise one of the most ubiquitous and conserved classes of proteins in biology. The diverse functions of iron-sulfur clusters in proteins range from electron transfer to redox signaling. The assembly of iron-sulfur clusters in cells requires a complex protein system and acquisition of sulfur and iron. While the sulfur source for iron-sulfur cluste....
