Hemp Microgreen Mineral Content, Cannabinoids, Total Phenolics, And Antioxidants, Cheston T. Schayot

LSU Master's Theses

Hemp (Cannabis sativa) L. microgreens were grown to 7 and 12 days with and without supplemental lighting and/or fertilizer. The principal macronutrient found in hemp microgreens was nitrogen (N), followed by potassium (K), phosphorus (P), magnesium (Mg), calcium (Ca), and sulfur (S). The principal micronutrient found in hemp microgreens was iron (Fe), followed by manganese (Mn), zinc (Zn), boron (B), and copper (Cu). Hemp microgreens were similar to other commonly grown microgreen species in minerals except for P and Mg, where they could potentially be an excellent source, and Zn, where they fell below previously reported amounts. The …

3-Dimensional Structural Determination Of Epidermal Growth Factor-Like Repeat 27 From Mouse Notch1 Using Nuclear Magnetic Resonance Spectroscopy, Justin Grennell

LSU Doctoral Dissertations

NOTCH1 has been associated with a variety of human ailments, such as cancer and heart disease. NOTCH1 is a transmembrane protein that contains 36 epidermal growth factor-like (EGF) repeats, which facilitate cell signaling by binding proteins on neighboring cells. Each repeat contains about 40 amino acids and has to be folded in a specific manner to function properly. The amino acid sequence, carbohydrate pattern, and calcium-binding sites of EGF-like repeats vary, but the pattern along the 36-repeat chain is conserved. The Abruptex region (EGF24-29) of NOTCH1 is a highly glycosylated (having undergone sugar addition) and flexible region, which gained its …

Investigation Of Bovine Herpesvirus-1 Determinants Of Neuronal Infectivity In Novel Bovine Neuronal Cell Systems For Development Of A Safer Viral Vaccine Vector, Jared Rudd

LSU Doctoral Dissertations

Bovine herpesvirus-1 (BoHV-1) is the causative agent of infectious bovine rhinotracheitis and a component of the bovine respiratory disease complex. BoHV-1 is a significant burden on the cattle industry in the United States causing severe respiratory disease, abortions, loss of calves (“shipping fever”). BoHV-1 belongs to the alphaherpesvirus subfamily of Herpesviridae. Alphaherpesviruses enter axons of sensory nerves and establish life-long latency in trigeminal and dorsal root ganglionic neurons after primary infection of the oronasal or genital epithelium respectively. Modified live attenuated vaccines for BoHV-1 are commercially available but are limited in their protection while retaining the ability to establish latency …

Time And Tide: Sixteenth-Century Expressions Of Temporality In The Writings Of Richard Hakluyt, Jennifer Hope Tellman

LSU Doctoral Dissertations

Richard Hakluyt the Younger (c. 1553-1616) was the most famous English promoter of overseas expansion of his age and in English history. His most renowned publication, Principal Navigations (1598-1600), a massive three-volume series, detailed English exploration, expansion, and trade history. With a focus on inciting the English to act in order to achieve their Providential Empire, Hakluyt’s works carry in them the expressions of time and temporality permeating the late-1500s. In a period of history where new learning, discoveries, and technologies began to transform life, time was called into question. Concerns about how the perception and acceleration of time and …

Role Of Aim2 Inflammasome In Pulmonary Host Defense Against Staphylococcus Aureus-Induced Pneumonia, Bibek Dhakal

LSU Master's Theses

Bacterial pneumonia is the leading cause of death in children under the age of five, claiming the lives of two million children each year. Staphylococcus aureus is the extracellular Gram-positive bacteria that causes necrotizing pneumonia. Moreover, the spread of antibiotic-resistant and hypervirulent strains has made treatment more challenging. Absent in melanoma 2 (AIM2) is a dsDNA-sensing cytosolic innate immune receptor that activates inflammasomes and is crucial for host defense against intracellular bacteria and DNA viruses. However, its role in extracellular bacterial pathogen-induced pneumonia is unclear. Therefore, understanding how AIM2 initiates host responses during Staphylococcus aureus is crucial for the development …

Looking Down From The Top Of A Redwood Tree, Keri Pertuit

LSU Master's Theses

“Looking Down from the Top of a Redwood Tree” was a collaboration with my brother, Fabein Miguel Disedare. From the onset of this project, I reached out to him about the possibility of him creating the poetry, functioning as the lyrics of this piece. When working with Fabein, he suggested the topic of global warming, and we agreed to incorporate this theme through the telling of a story from the perspective of Redwood Tree located on the California coast. This song cycle follows the story of a family of trees inhabiting the coastline, their struggles with deforestation, their lack of …

Investigation Of Arabidopsis Extremophyte Relatives, Schrenkiella Parvula And Eutrema Salsugineum Reveals Different Roads Leading To Salt Stress Tolerance, Kieu-Nga Thi Tran

LSU Doctoral Dissertations

How plants adapt to salt stress has been a central question in plant biology for decades. Yet we have not been able to fully understand the molecular networks and genetic mechanisms underlying this complex trait. Most of the genetic work on salinity stress has focused on understanding salt stress responses in the leading, yet a salt-sensitive model Arabidopsis thaliana. With the recent availability of genomes for wild-relatives of A. thaliana, we can now investigate how naturally salt adapted plants may have evolved modified or novel molecular networks to adapt to salt stress. Therefore, my research utilizes a comparative …

Income Inequality And Polarization In The United States, Tatum Colette Taylor

LSU Doctoral Dissertations

Economic inequality has been on the rise in the United States for decades, as has political polarization. Pulling from grievance theory and relative deprivation theory, I explore the relationship between these two trends, predicting economic inequality may actually contribute to citizen polarization. I also predict that polarization of identities, issue opinions, and feelings towards groups polarize differently. In this study I test using linear regression analysis and data primarily from the American National Election Study whether income inequality and perceived growth of the income gap over 20 years affect ideological, substantive, and affective polarization from 2004-2016. I also examine the …

Insights Into Abscisic Acid And Phosphatidic Acid Signal Transduction Dynamics In Arabidopsis Thaliana, Ruth Wanjiru Ndathe

LSU Doctoral Dissertations

Abscisic acid (ABA) is a plant hormone that triggers a signaling transduction in response to drought, salinity, and cold. The core components in the ABA signaling pathway that lead to downstream ABA responses have been identified.

Phosphatidic acid (PA) is a membrane phospholipid that is involved in the signaling pathway for ABA-induced stomatal closure. We tested whether PA is involved in the signaling pathway for ABA-induced gene expression as well, using model plant Arabidopsis thaliana. We selected the RD29A gene which is a canonical drought gene that is induced by ABA. We found that PA is not involved in …

Pore-Scale Modeling Of Fluid Flow And Particle Transport In Multi-Scale Porous Media, Bin Wang

LSU Doctoral Dissertations

Nanomaterials have recently gained much interest in the field of petroleum engineering and environmental engineering. Understanding the particle transport mechanisms in geological porous media is important to design fit-for-purpose nanomaterials and certain operating parameters for practical usage of those materials. It has been known that natural rock has multi-scale porosity (macroporosity and microporosity) in nature. The microporosity can have a strong impact on the flow and mass transport, but the microscale physics and macroscopic consequences remain poorly understood.

The first part of this dissertation introduces a new higher-order, locally mass conserving FEM method. Stokes equation and Darcy equation are solved …

Evaluating Substrate Stratification Practices For Enhanced Water Resource Management In Nursery Production, Kristopher S. Criscione

LSU Master's Theses

The nursery and greenhouse industries have continued to increase in production and sales over the past two decades. This increase in horticultural production necessitates a greater demand for finite natural resources, specifically water. Sustainable water resource management will be critical to the success and continual growth of the nursery industry. Strategic irrigation scheduling and innovative substrate management practices can improve nursery resource efficiency. Soilless substrates were originally utilized by the industry to increase substrate air-filled porosity, to ensure adequately drained container systems. Thus, the implementation of these soilless substrates can lead to an inefficient use of water and fertilizer. Substrate …

Casting A Critical Lens On Global Development: A Multimethod Investigation Of The Masculine Hegemonic Forces That Marginalize Women In Agriculture, Morgan Alyse Richardson Gilley

LSU Doctoral Dissertations

A critical link between gender equality and agricultural development has been established in the literature. However, disparities between genders have persisted in many areas of the developing world. One strategy that has been used to reduce gender inequalities has been educational outreach opportunities through agricultural extension, which has provided women a critical pathway to empowerment. Despite this, a lack of knowledge on the experiences of women in agriculture throughout Southeast Asia has served as a barrier to the advancement of such work. This investigation sought to better understand the issues facing this region’s fight to attain gender equality. To achieve …

Real Space Quantum Cluster Formulation For The Typical Medium Theory Of Anderson Localization, Ka Ming Tam, Hanna Terletska, Tom Berlijn, Liviu Chioncel, Juana Moreno

Faculty Publications

We develop a real space cluster extension of the typical medium theory (cluster-TMT) to study Anderson localization. By construction, the cluster-TMT approach is formally equivalent to the real space cluster extension of the dynamical mean field theory. Applying the developed method to the 3D Anderson model with a box disorder distribution, we demonstrate that cluster-TMT successfully captures the localization phenomena in all disorder regimes. As a function of the cluster size, our method obtains the correct critical disorder strength for the Anderson localization in 3D, and systematically recovers the re-entrance behavior of the mobility edge. From a general perspective, our …

Sustainable Gardening For School And Home Gardens: Radish, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Radish is a root crop and member of the Brassicaceae family, also known as the cabbage family, which includes other cool-season crops like cabbage, kale, collards, broccoli and cauliflower. The name radish comes from the Latin word for “root” and a Greek expression that translates into “easily reared.” Western Asia (likely China) is considered the country of origin for the wild form, and it was first recorded around 2000 B.C. in Egypt. Radishes were especially popular and highly regarded with the Greeks. The original radish was probably larger and slow-growing, similar to Daikon radish.

Sustainable Gardening For School And Home Gardens: Lettuce, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Lettuce is a member of the Asteraceae family, also known as the aster or sunflower family, which includes crops such as globe artichokes and endive, but also garden ornamentals like sunflowers, dahlias, marigolds and zinnias. Cultivated lettuce likely developed from wild lettuce from the Mediterranean area of the Middle East and was first recorded in ancient Egypt around 2500 B.C. in tomb paintings but may have been as early as 4500 B.C. This original lettuce had two main types: one with much thicker stems (like celery) and another that produced seeds used for cooking oil. The stem lettuces (similar to …

Sustainable Gardening for School and Home Gardens

Collards and kale are both members of the Brassicaceae family, also known as the cabbage family, which includes other cool-season cole crops like cabbage, broccoli, Brussels sprouts, cauliflower and radish. However, collards and kale are distinct from much of the cabbage family because they do not form heads; instead their leaves are harvested.

Sustainable Gardening For School And Home Gardens: Eggplant, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

The eggplant is a member of the Solanaceae family, also known as the Nightshade family, which includes crops such as the Irish potato, tomato, tomatillo and pepper. The eggplant is thought to have originated in Asia (mainly parts of India and Burma/Myanmar), and the first record of this vegetable was from a 5th century Chinese book. The original eggplant was a wild plant with orange, pea-sized, spiny fruit — very different than the present-day eggplant!

Sustainable Gardening For School And Home Gardens: Cucumber, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Cucumbers are members of the Cucurbitaceae family, also known as the cucurbits or gourd family. The group includes crops such as winter and summer squash, watermelon, cantaloupe, pumpkins and gourds. It is believed that cucumbers originated in India over 3,000 years ago and then spread to China, Greece, Italy and North Africa (see Figure 2). By the 9th century, cucumbers were grown in France, likely transported by the Romans. They were not documented in England until the 14th century. Cucumbers were then transported to the Americas during colonization, led by Columbus around the mid-1500s, and were grown in early Virginia …

Sustainable Gardening For School And Home Gardens: Citrus, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Citrus trees are members of the Rutaceae family, also known as the Rue family, which includes mostly flowering woody trees and shrubs. Trees in this family produce citrus fruits, including popular crops for Louisiana, such as satsumas, oranges and kumquats (see Figure 1). Citrus trees cannot survive in areas that regularly freeze, so production is concentrated along the Gulf Coast, particularly in southern areas of Louisiana and Florida.

Sustainable Gardening For School And Home Gardens: Cabbage, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Cabbage and Chinese cabbage are members of the Brassicaceae family, also known as the cabbage, mustard or crucifer family, which includes other cole crops like broccoli, cauliflower, kale, collards, kohlrabi and radishes. Both cabbage and Chinese cabbage are cool-season, frost-tolerant crops that are widely adapted to temperate and subtropical regions. The center of origin of cabbage is most often considered to be the coastal areas of the Mediterranean, the British Isles and Western Europe. Cabbage is thought to have been first grown by the Greeks for medicinal purposes over 3,000 years ago. Today’s cabbage varieties are likely derived from wild, …

Sustainable Gardening For School And Home Gardens: Sweet Pepper, Johannah Frelier, Denyse Cummins, Carl Motsenbocker

Sustainable Gardening for School and Home Gardens

Peppers are likely native to the Oaxaca region of Mexico, where they are referred to as chiles, with evidence dating back to 5000 B.C. Peppers were also widely produced in Guatemala, and evidence of this crop’s presence in Peru was documented in 1609. They were transported by Spanish and Portuguese explorers and adapted to many different climates. Columbus discovered pungent (hot) peppers in the West Indies and coined the name “pepper.” By the 16th century, peppers were introduced to Europe but were not commercially produced in the southern U.S. until 1925.
