Exploring Caffeyl-Lignin Biosynthesis in Cleome hassleriana and Polymerization of Caffeyl Alcohol in Arabidopsis thaliana

Description: C-lignin (caffeyl-lignin) is a novel linear lignin polymer found in the seed coats of several non-crop plants, notably Vanilla planifolia (Vanilla), Jatropha Curcas (Jatropha), and Cleome hassleriana (Cleome). C-lignin has several advantages over normal G/S-lignin, found in the majority of lignocellulosic biomass, for valorization in the context of bioprocessing: less cross-linking to cell wall polysaccharides (less recalcitrant biomass), ordered linkages between monomers (homogeneous polymer),… more

Famine Fighters: American Veterans, the American Relief Administration, and the 1921 Russian Famine

Description: This study argues that the American Relief Administration (ARA) operationally and culturally was defined by the character and experiences of First World War American military veterans. The historiography of the American Relief Administration in the last half-century has painted the ARA as a purely civilian organization greatly detached from the military sphere. By examining the military veterans of the ARA scholars can more accurately assess the image of the ARA, including what motivated their … more

A Shaping Procedure for Introducing Horses to Clipping

Description: The purpose of the current study is to evaluate a procedure that can be used to introduce horses to clipping. Negative reinforcement was used in a shaping paradigm. Shaping steps were conducted by the handler, starting with touching the horse with the hand, then touching the horse with the clippers while they are off, culminating with touching the horse with the clippers while they are on. When a horse broke contact with either the hand or the clippers, the hand or the clippers were held at tha… more

Effects of Customer's Evaluation about Instagram Attributes towards Purchase Intentions for Small Apparel Retailers: Application of Social Capital Theory

Description: Small apparel retailers face extreme competition with larger retailers. Large retailers have the upper hand in resources to stay updated with various trends, specifically social media. Social media has lowered the barriers to enter the retail industry. However, once these small retailers enter, half of them fail because they don't attract and retain customers. Small-medium enterprises (SMEs) greatly impact the economy, so it is important to study various facets of their business to increase per… more

Creating the Character of North Texas: Demographics and Geography, 1841-1861

Description: Several historians have identified North Texas as constituting a unique cultural region in antebellum Texas, due to the more limited cotton and slave economies and greater opposition to secession. Different settlement patterns have been put forward as an explanation for the distinct "character" of North Texas, with North Texas being portrayed as being settled largely by migrants from the Upper South while the rest of the state was primarily settled by Lower Southerners. The argument rests on th… more

We hypothesized that bullying in adolescence would be associated with witnessing parental IPV in adolescence and IPV in young adulthood. We believed that deficits in social information processing, particularly hostile attribution biases, would be associated with adolescent bullying. Lastly, we believed that decenteri… more

A Feasibility Study of Cellular Communication and Control of Unmanned Aerial Vehicles

Description: Consumer drones have used both standards such as Wi-Fi as well as proprietary communication protocols, such as DJI's OcuSync. While these methods are well suited to certain flying scenarios, they are limited in range to around 4.3 miles. Government and military unmanned aerial vehicles (UAVs) controlled through satellites allow for a global reach in a low-latency environment. To address the range issue of commercial UAVs, this thesis investigates using standardized cellular technologies for com… more

Optical Brain Imaging of Motor Cortex to Decode Movement Direction using Cross-Correlation Analysis

Description: The goal of this study is to determine the intentional movement direction based on the neural signals recorded from the motor cortex using optical brain imaging techniques. Towards this goal, we developed a cross-correlation analysis technique to determine the movement direction from the hemodynamic signals recorded from the motor cortex. Healthy human subjects were asked to perform a two-dimensional hand movement in two orthogonal directions while the hemodynamic signals were recorded from t… more

Teaching Children How to Stay Still Using Movies to Provide Continuous Feedback

Description: External beam radiation therapy is often used as a form of treatment for individuals diagnosed with cancer. However, because staying completely still can often be difficult for children, sedation is often used daily to remedy the need for stillness. In this document, we introduce the development, implementation, and testing of a technology designed to teach healthy children to self-monitor and control their movements. This technology monitored a child's body movement and created a continuous fe… more

La vía del abandono en los cuentos de Amparo Dávila

This study proposes that the sinister in Davila's stories are created by abandonment. This abandonment is the peremptory element of Davilian narrative and can be seen and examined throughout the author's literary w… more
