Abstract: Sugarcane (Saccharum officinarum) is Louisiana's number one row crop. Growing and processing sugarcane produces significant amounts of byproducts, including bagasse, crop residue, molasses, filter-press mud, and boiler fly ash. These products represent an important opportunity to generate value-added and specialty products and enhance sugarcane's sustainability by facilitating a circular economy, where agricultural by-products are reused instead of disposing them (linear economy), in order to reduce resource use and energy demand. Examples of value-added products range from biochar, construction materials, animal feed, biofuels, nanoparticles, and fertilizer. Paramount to the success of the bio-based circular economy is creating useful products that …

Substituent Effects On The Photophysical Properties Of A Series Of 8(Meso)-Pyridyl-Bodipys: A Computational Analysis Of The Experimental Data †, Petia Bobadova-Parvanova, Dylan Goliber, Elijuah Hernandez, Daniel Lamaster, Maria Da Graça H. Vicente

Faculty Publications

Recently, a series of 8(meso)-pyridyl-BODIPYs (2-pyridyl, 3-pyridyl, and 4-pyridyl) and their 2,6-substituted derivatives were synthesized and their structure and photophysical properties were studied both experimentally and computationally. One of the main observed trends was that the 2-pyridyl-BODIPYs were consistently less fluorescent than their 3-pyridyl and 4-pyridyl analogs, regardless of the 2,6-substituents. Herein, we extend our previous computational studies and model not only the ground but also the excited states of the entire series of previously synthesized meso-pyridyl-BODIPYs with the aim of explaining the observed differences in the emission quantum yields. To better understand the trends and the effect of 2- …

Evaluating The Success Of A Relocated Mussel Community In The Lower Sulphur River, Texas, Rachel M. Leicher

Biology Theses

Conservation efforts to preserve freshwater mussel communities have become more common as these animals become increasingly threatened by their changing habitats. As humans continue to shape and change the world around them, aquatic species living in modified and disturbed water systems can be negatively impacted leading to decline of the ecosystem. During disturbance events involving a stream, river, or pond, the relocation of affected mussel beds is becoming more widespread. Although there are few of these studies, many of those that have been conducted are seen as successful in relocating and conserving their mussel communities. This study focuses on detection …

Blood Biomarkers In Down Syndrome: Facilitating Alzheimer's Disease Detection And Monitoring, Melissa Petersen, Lisi Flores-Aguilar, Elizabeth Head, Laia Montoliu-Gaya, Andre Strydom, Sarah Pape, Juan Fortea, Nicholas Ashton, Chinedu Momoh, Sid O'Bryant

Brain and Mind Institute

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer's Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

Wilczek] Through Phenology, Growth, Protein Yield, And Cluster Heatmap Analysis, Rafiqul Islam, Jamil Hossain, Shamsul Huda, Mohammad Golam Azam, Faruk Hossain, Aktar Uz Zaman, Safiqul Moula, Nasir Uddin Ahmed, Jamal Hossain, Ayman El Sabagh, Mohammad Sohidul Islum

The Philippine Agricultural Scientist

Mung bean [Vigna radiata (L.) Wilczek] cultivation is challenging under the changing climate as less precipitation during the summer season, which is becoming increasingly common, results in soil moisture deficiency and affects production especially at the early growth stages. Hence, this study was conducted to assess the phenology, growth, and protein yield traits of mung bean related to drought tolerance. Eight mung bean genotypes were grown in pots inside a rain-out shelter under well-watered (WW) and water-deficit (WD) conditions. These genotypes included four water stress-tolerant genotypes: G-1 (BARI Mung-8), G-2 (BMX-010015), G-3 (BMX-08010-2), and G-4 (BMX-08009-7), as well as four …

Comparing Conventional And Modified Cage Wheel Performance In Lowland Conditions, Rosalinda Abad, Michael Duldulao, Arthur Fajardo

The Philippine Agricultural Scientist

In agricultural production, significant cost consumption from tillage due to high energy input and low work performance may be reduced by improving the design of hand tractor components, specifically tractive devices. This study aimed to compare the field performance of conventional and modified cage wheels for hand tractors in terms of field efficiency (FE), wheel slip, and fuel consumption (FC). Using the Philippine standard methods of testing for walking-type tractors and a two-tailed t-test to analyze the data, results showed that the modified cage wheel had an FE of 90.09%, wheel slip of 7.78%, FC of 0.22 L/h, and FC …

Rehydration Kinetics Of Green Pea Grains Dried At Different Microwave Powers, Serap Kayisoglu

The Philippine Agricultural Scientist

In this study, both untreated and pre-treated green pea grain samples dried at different microwave output powers (90, 180, and 360 W) were rehydrated at three different temperatures (30ºC, 50ºC, and 70ºC). The rehydration kinetics of dried peas were analyzed using both the Peleg and the first-order kinetic models. Observations revealed that the Peleg model exhibited better agreement with the experimental data. As both microwave power and rehydration temperature increased, the rehydration capacity also increased in both pre-treated and untreated peas. The highest moisture content was observed after rehydration in pre-treated peas dried at 360 W microwave power (2.80 g …

Thermal Anharmonicity Of Transition Metals: A Case Study Of Tantalum, Bimal K C

Open Access Theses & Dissertations

Density functional theory (DFT) is commonly used for evaluating the thermal propertiesand equation of state of solids, usually within the quasi-harmonic approximation (QHA). In transition metals, thermodynamic quantities such as the thermal pressure and Gruneisen parameter are poorly reproduced compared with experimental values or with direct computational methods like quantum-molecular dynamics (QMD) simulations. Surprisingly, there has not been to date, a systematic study aimed at understanding the reasons for these discrepancies. Using Tantalum as a case study, we have evaluated the temperature dependence of the phonon frequencies employing Harmonic Ensemble Lattice Dynamics (HELD) combined with classical and quantum molecular dynamics. …

Indisposed To Write: Teaching A Visceral Poetics, Miriam L. Atkin

The Journal of the Assembly for Expanded Perspectives on Learning

This essay begins from the premise that acts of thinking and writing are shaped immanently by corporeal need. Accordingly, my aim is to sketch a vision of composition pedagogy that acknowledges the moves and modulations of the thinking body. The route I take to get there explores four works of critical prose that mobilize form and content toward a radical re-orientation of body-in-space and body-in-writing. These texts—by Eleni Stecopoulos, Robert Kocik, William James, and Eli Clare—are to varying degrees experimental, demonstrating a manner of textual difficulty that signals the visceral difficulty implied in any act of writing. What follows is …

The Effect Of Common Road Salts And Organic Additives On Microbial Respiration In Urban Streams, Claire Meara

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Due to significant population growth and urbanization, there has been an increase in impervious surfaces such as roads and sidewalks. During winter, impervious surfaces are often treated with salt to make road conditions safer. However, this has significant impacts on water quality when salt enters urban streams during runoff events. The addition of road salts to urban streams has been shown to have detrimental effects to various organisms across trophic levels and affects nutrient cycling and greenhouse gas release. These findings have made the development of alternative treatments necessary, such as using organic additives, like beet juice, which can decrease …

Valor: Villains, Creatures And Foes - A Tabletop Roleplaying Game Expansion And A Methodology For Planning And Managing Tabletop Roleplaying Game Projects, Erik Ryan Ottosen

Student Projects for Graduate Degrees

Valorous Games, an independent developer and producer of Tabletop Roleplaying Games (or TTRPGs), has successfully executed three book development projects over the past seven years (the third project being a reprint and update of their first book), in addition to smaller ancillary projects. In 2023, it was determined that rescoping and restarting their third book, Valor: Villains, Creatures and Foes, would better align with future goals for the company and its proprietor. Initial research showed that little to no academic material exists for study of Project Management (or PM) in the context of the Tabletop Role-Playing Game hobby; thus, it …

How Detrimental Is Transunion V. Ramirez, Really? Understanding The Impact On Environmental Law, Lauren Young

Washington Law Review

In 2021, the United States Supreme Court issued a controversial opinion with the potential to constrict the standing doctrine. TransUnion v. Ramirez appeared to alter standing’s “concrete harm” requirement, which would significantly restrict plaintiffs’ ability to invoke the jurisdiction of federal district courts. Building off its 2016 case, Spokeo v. Robins, the Court declared that intangible harms are only concrete when “plaintiffs have identified a close historical or common-law analog[] for their asserted injury.” The “common-law analog[]” required a “close relationship to harms traditionally recognized as providing a basis for lawsuits in American courts.” The Court mandated this requirement …

Building Social Capital In Nonprofit Human Service Organizations, Glenn M. Birch

School of Professional and Continuing Studies Nonprofit Studies Capstone Projects

All forms of capital enhance the ability to accomplish tasks efficiently. Like physical, human, and financial capital, social capital enables individuals or organizations to accomplish more than is otherwise possible. When groups undertake actions to cooperate and achieve a shared purpose, it is a sign of social capital at work. This study looks specifically at human service nonprofit organizations to examine strategies and practices that can lead to the building of social capital. As a comparative case study of two nonprofit organizations, I explore how nonprofit organizations learn to build social capital across lines of difference; look at how bridging …

The Tenth Circuit's Blueprint For Minimizing En Banc Rehearings, Steven M. Foster Jr., Anthony R. Guttman

Denver Law Review

The Tenth Circuit is known for two things: its collegiality and its downward trend of en banc rehearings. Recognizing this trend, two Tenth Circuit judges recently outlined in the Denver Law Review “best practices” for submitting en banc petitions. In response, some scholars propose that this practitioner’s guide is not worth the read because of the larger problem at hand. Namely, they predict that even with better petitions, the Tenth Circuit will remain unwilling to rehear cases en banc, thereby decreasing intracircuit uniformity. But this prediction overlooks key factors driving the trend. This Response accounts for one contributing factor—collegiality—causing the …

Daca's Major Questions Exception, Matthew Calabrese

Hofstra Law Review

The Supreme Court has extracted a new role as the gatekeeper of administrative action under the major questions doctrine. Underlying the doctrine is an understanding that agencies cannot act to address policy issues implicating questions of great political and economic significance unless specifically authorized by Congress. However, DACA presents a different question that should be exempted from the major questions doctrine. This is because DACA relies on two levels of executive authority: statutory—under the Immigration and Nationality Act and the Homeland Security Act—and constitutional—under the Take Care Clause. Because, as this Article explains, the two authorities cannot be disentangled, courts …

In The Mix: Hip Hop's Impact On Genre Development And Cultural Influence In African And Jamaican Music, Kinzi Kabadeh

Postgraduate

In this exegesis, I contend that certain compositional elements and production methods of dancehall, amapiano, and afrobeats demonstrate hip hop’s influence on contemporary Jamaican and African electronic music. In particular, the drum programming, track mixing, and use of sampling demonstrate a cross-pollination and cultural transfer between the two forms of music (on one hand, the African and Jamaican genres of dancehall, amapiano, and afrobeats, and on the other, the African American music of hip hop). These genres are fundamental to contemporary Black culture and share origins as vehicles for resistance to oppressive forces.
