Effect Of Biochar On Enteric Methane Production And Cattle Performance, Hanna Cronk, Holly Heil, Rebecca Mcdermott, Mitch Norman, Galen E. Erickson, Andrea Watson

Nebraska Beef Cattle Reports

Methane is a more potent greenhouse gas than carbon dioxide. Because ruminant animals, including cattle, emit methane, strategies are actively being sought to reduce these emissions. Pistachio shell-sourced biochar was included at 0.5% of a finishing cattle diet to determine effects on methane emissions and cattle performance. Eight pens of cattle were rotated through a 2-chambered emissions barn to analyze methane and carbon dioxide produced by the cattle. Biochar tended to increase methane emissions on a g/d basis with no effect on methane emissions as g/lb of feed intake and no differences in carbon dioxide emissions. There were no differences …

Impact Of Strip-Grazing Stockpiled Annual/Cover Crop Forages On Carrying Capacity And Animal Performance, Shelby L. Davies-Jenkins, Abigail Sartin, Devin Jakub, Zac Carlson, Erin Laborie, Jack Arterburn, Ben Beckman, Brad Schnick, M. E. Drewnoski

Nebraska Beef Cattle Reports

Annual forages/cover crops can be used to fill the fall/winter grazing gap, and strip grazing may increase carrying capacity by reducing trampling losses of the forage. The current experiment utilized a series of on-farm experiments across two growing seasons to compare continuous and strip grazing of various summer planted cover crops. Strip grazing increased carrying capacity by an average of 47 ± 15% and gain per acre by 44 ± 5% compared to continuous grazing although significant variability in the amount of increase was observed. This variability can likely be attributed to forage type (quality), frequency of moves, and forage …

Strategies For Ddgs Supplementation Frequency To Frazing Yearling Streers, Sydney T. Vanderhoff, Rebecca L. Sjostrand, Mitchell M. Norman, Isaque F. Vicci, Jim C. Macdonald, Mary E. Drewnoski

Nebraska Beef Cattle Reports

Infrequent supplementation saves labor and may reduce animal performance, but recent research with reduced fat distillers grains has provided inconsistent results. This experiment evaluated the effects of daily and three times a week supplementation of dried distillers grains on yearling steer performance grazing smooth bromegrass pastures from May to August. Daily supplemented steers received 5.6 pounds of dry matter per steer of dried distillers grains with solubles 7 days/week. The three times a week supplemented steers received 13.0 pounds of dry matter per steer of dried distillers grains with solubles three days/week (Monday, Wednesday, Friday). A control treatment received no …

Effect Of Methionine Supplementation During Late Gestation In Beef Females, Landon F. Tadich, Jim R. Teichert, Kathryn J. Hanford, Jacki A. Musgrave, Rich N. Funston

Nebraska Beef Cattle Reports

Some amino acids are known to be essential to cattle and effect protein availability to the animal, especially during gestation when nutrient requirements are higher. Methionine is found to be one of the most limiting in low quality forage diets. Two 3-yr studies were performed to evaluate the impact of methionine supplementation during late gestation on intake, body weight, average daily gain, and subsequent calf performance in primiparous and multiparous females. In exp 1, 120 artificially inseminated pregnancy heifers were placed in a Calan gate feeding system (n=40/yr) and assigned 1 of 3 treatments during late gestation and fed ad …

Impact Of Prolonged Exposure To Occasional And Regular Waterpipe Smoke On Cardiac Injury, Oxidative Stress And Mitochondrial Dysfunction In Male Mice, Naserddine Hamadi, Suhail Al-Salam, Sumaya Beegam, Nur Elena Zaaba, Ozaz Elzaki, Abderrahim Nemmar

All Works

Regular waterpipe smoking (Reg-WPS) is well recognized for its deleterious effect on the heart. However, there is a paucity of experimental studies on the impact of occasional waterpipe smoking (Occ-WPS), also known as nondaily smoking, versus Reg-WPS on cardiac homeostasis, and the mechanisms underlying these effects. Hence, we aimed, in the present study, to investigate the effect of Occ-WPS (30 min/day, 1 day/week) versus Reg-WPS (30 min/day, 5 days/week) for 6 months on systolic blood pressure (SBP), cardiac injury, oxidative markers, chemokines, proinflammatory cytokines, DNA damage and mitochondrial function compared with air (control) exposed mice. Our results show that SBP …

Understanding Pluriversal Ontology: The Cases Of Three Alternative Agriculture Communities In Sisaket Province, Northeastern, Thailand, Thita Ornin

Chulalongkorn University Theses and Dissertations (Chula ETD)

In reaction to the global development paradigm, the concept of Pluriverse has played a pivotal role in exploring alternatives to development, aiming to foster a world that accommodates multiple worlding with the goals to facilitate various approaches to collective well-being, moving away from anthropocentric, linear growth within the modern capitalist development. This thesis seeks to understand alternative agriculture cases in the Northeast of Thailand through the Pluriversal ontology conceptual framework and to determine its usefulness through the following proposed framework; (1) alternative agricultural development discourse analysis, (2) friction and assimilation with modernity and (3) post-development values. Taken an inspiration from …

Thailand's Never-Ending Pesticide Debate: Contested Future Sociotechnical Imaginaries Through A Relational Co-Productionist Lens, Henriette Erawan Kamphorst

Chulalongkorn University Theses and Dissertations (Chula ETD)

Since the introduction of the Green Revolution, the use of agrochemicals in Thai farming has sparked repeated contentious debates among local policy elites, addressing issues such as consumer health, farmer livelihoods, and environmental degradation. In 2019, this subject re-emerged on the policy agenda with the proposed ban of three key agrochemicals: Chlorpyrifos, Paraquat, and Glyphosate. In order to understand why the pesticide issue has remained on policy actors’ agendas for so long and still continues to be subject to ongoing debate, this research takes on a new perspective by adopting a relational co-productionist approach in the construction of contesting sociotechnical …

Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster Christenson, Jordan Thomas, Daniel J. Kelly, John G. Maddux, R. Funston

Nebraska Beef Cattle Reports

The study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen at ranch 1 and demonstrated pregnancy to multi-sire sexed semen at rand 2. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Ranch 1 heifers were inseminated with either single-sire or multi-sire semen and all heifers expressing estrus at ranch 2 were inseminated with multi-sire semen averaged numerically greater pregnancy rate than the average single-sire pregnancy rate and pregnancy outcomes from multi-sire sexed semen exceed previous literature but cannot be directly compared. Despite similar pregnancy results between …

Long-Term Performance Of Steers Grazing Smooth Bromegrass Pastures, Morgan Hodges, Holly Heil, Rebecca Mcdermott, Anastasios Mazis, Tala Awada, Galen E. Erickson, Andrea K. Watson

Nebraska Beef Cattle Reports

Summary with Implications

Body weight gain of yearling steers grazing smooth bromegrass pastures was measured across 17 years from 2005 to 2021. Three treatments were applied, (1) control pastures with no additional inputs, (2) pastures fertilized with 80 lb of N per acre, and (3) pastures grazed with cattle supplemented daily with approximately 5 lb of dry distillers grains. The cnntrol treatment pastures (1.4 acres/steer) were stocked 30% lighter than the fertilized and supplemented pastures (1.0 acre/steer). Across the 17 years, the supplemented cattle gained 2.24 lb/day while the non-supplemented cattle (both control and fertilized treatments) gained 1.57 lb/day. Body …

Open Hunting Season: Black Bodies As A Threatened Species, Mark C. Grafenreed

Cardozo Journal of Equal Rights & Social Justice

Tracing the Endangered Species Act of 1973 provides striking parallels with the historical, legal, and cultural aspects of bondage mapped upon Black bodies. The United States Congress promulgated the Endangered Species Act to protect and conserve threatened and endangered wildlife species. However, this gives rise to a serious moral dilemma and cognitive dissonance in that nearly 1,500 wildlife species benefit from the Endangered Species Act's protections. At the same time, Black bodies disproportionately suffer without similar federal protections. Congress has strengthened the Endangered Species Act's force through four amendments since its inception, even while there have been mounting threats to …

If It Can Make It There, It Can Make It Anywhere: How New York's "Green Amendment" Is Catalyzing Environmental Progress In Light Of Federal Failures, Zoe Zingale

Cardozo Journal of Equal Rights & Social Justice

The note examines the challenges faced by minority and low-income communities in seeking legal redress for environmental injustices, highlighting how federal legal avenues like Title VI of the Civil Rights Act of 1964 have been limited by Supreme Court rulings. It proposes that state-level Green Amendments, such as New York's, offer a promising alternative for these communities to assert their right to a healthy environment and seek relief from disparate environmental impacts.

Corporate Human Trafficking, Carliss Chatman

Faculty Journal Articles and Book Chapters

The utilization of the internet for human trafficking and sexual exploitation is not an issue that can be tackled one corporation, one country, or one market sector at a time. It is an international problem that requires broader solutions that can protect and provide remedy to victims without chilling the freedom of speech and freedom of contract of consensual parties engaged in sex work. Recent changes to laws related to human trafficking have strengthened the power of litigation, authorizing civil lawsuits against perpetrators of human trafficking that may include third-parties who knowingly benefit from trafficking conduct—such as internet providers, business …

The Death Of The Evolving Standards Of Decency, Meghan J. Ryan

Faculty Journal Articles and Book Chapters

The Eighth Amendment Punishments Clause is in jeopardy. The constitutionality of punishments is usually judged according to the “evolving standards of decency that mark the progress of a maturing society.” And in evaluating these standards, the Court has traditionally looked to changing societal views on punishment. This is a living constitution approach to interpretation, and the Eighth Amendment is the only area of law in which the Court has consistently and explicitly ap-plied such an approach. But a living constitution approach is diametrically opposed to the current Court’s focus on originalism. This is the first originalist Court in history, and …

Privacy Law’S Role In An Information Economy, Sari Mazzurco

Faculty Journal Articles and Book Chapters

What do we lose when we lose our privacy? A slew of recently enacted state laws suggest that the loss of privacy is merely a loss of individual choice in the market exchange of services for personal information. This Article argues that a loss of privacy risks something greater: the collapse of complex and fluid social identity. Without privacy, individuals cannot nurture their own senses of self because they are no longer free to try on different social roles across diverse relationships. Pervasive, private data collection threatens multifaceted selfhood by eliminating the boundaries that make social roles distinct and hindering …

Reimagining The Inclusive Jury, Anna Offit

Faculty Journal Articles and Book Chapters

At the height of the COVID-19 pandemic, everyday life for many Americans was upended. And yet, the jury trial remained viable — even vital. Faced with an era-defining public health disaster, courts innovated, embracing novel technologies and techniques to reimagine where and how justice might be made. But why did it take a pandemic to spur this kind of institutional creativity? Prior to the outbreak of COVID-19, people who were otherwise eligible to participate as jurors were routinely — and uncontroversially — struck or exempted from service due to limited mobility, vision and hearing loss, and caregiving responsibilities. Recent experience …

The Volokh Briefs: Drawing The Line Against Compelled Speech In Public Accommodations, Dale Carpenter

Faculty Journal Articles and Book Chapters

In a series of important amicus briefs (the “Volokh Briefs”) filed over the course of about a decade, Professor Eugene Volokh was the principal architect of an argument for protecting expressive goods and services offered for sale the commercial marketplace.  This free speech protection would override certain applications of state antidiscrimination law.

The argument bore fruit in 303 Creative v. Elenis (2023), which held that under the First Amendment’s Free Speech Clause the state could not force a designer to fashion websites incorporating the designer’s customized text and graphics for the celebration of same-sex weddings. As Volokh and others urged, …

Estimation Of Differential Pathlength Factor From Nirs Measurement In Skeletal Muscle, B. Koirala, A. Concas, A. Cincotti, Yi Sun, A. Hernández, M. L. Goodwin, L. B. Gladden, N. Lai

Electrical & Computer Engineering Faculty Publications

The utilization of continuous wave (CW) near-infrared spectroscopy (NIRS) device to measure non-invasively muscle oxygenation in healthy and disease states is limited by the uncertainties related to the differential path length factor (DPF). DPF value is required to quantify oxygenated and deoxygenated heme groups' concentration changes from measurement of optical densities by NIRS. An integrated approach that combines animal and computational models of oxygen transport and utilization was used to estimate the DPF value in situ. The canine model of muscle oxidative metabolism allowed measurement of both venous oxygen content and tissue oxygenation by CW NIRS under different oxygen delivery …

Resistance to temozolomide (TMZ), the frontline chemotherapeutic agent for glioblastoma (GBM), has emerged as a formidable obstacle, underscoring the imperative to identify alternative therapeutic strategies to improve patient outcomes. In this study, we comprehensively evaluated a novel agent, O6-methyl-2'-deoxyguanosine-5'-triphosphate (O6-methyl-dGTP) for its anti-GBM activity both in vitro and in vivo. Notably, O6-methyl-dGTP exhibited pronounced cytotoxicity against GBM cells, including those resistant to TMZ and overexpressing O6-methylguanine-DNA methyltransferase (MGMT). Mechanistic investigations revealed that O6-methyl-dGTP could be incorporated into genomic DNA, disrupting nucleotide pools balance, and inducing replication stress, resulting in S-phase arrest and DNA damage. The compound exerted its anti-tumor properties …

Understanding The Significance Of Object Recognition In Cowbirds: Exploring The Interplay Of Cognition, Social Behaviour And Reproductive Success, Eric Rushton

Theses and Dissertations (Comprehensive)

Every day, animals use cognitive processes to make decisions in their environment such as those regarding food sources, threats and mates. One such important process provides the ability to recognize objects and individuals in order to guide future actions. Since object recognition and individual recognition are related processes, they may be linked to social cognition and to fitness; links not commonly explored in the literature. In this thesis I seek to examine (1) how brown-headed cowbirds (Molothrus ater) attend to and react to novel objects in their environment and (2) how this ability to recognize objects is related …

Upcycling Imperfect Broccoli And Carrots Into Healthy Snacks Using An Innovative 3d Food Printing Approach, Safoura Ahmadzadeh, Taylor Clary, Alex Rosales, Ali Ubeyitogullari

Food Science Faculty Publications and Presentations

Vegetables are healthy foods with nutritional benefits; however, nearly one-third of the world's vegetables are lost each year, and some of the losses happen due to the imperfect shape of the vegetables. In this study, imperfect vegetables (i.e., broccoli and carrots) were upcycled into freeze-dried powders to improve their shelf-life before they were formed into food inks for 3D printing. The rheology of the food inks, color analysis of the uncooked and cooked designs, and texture analysis of the cooked designs were determined. The inks with 50% and 75% vegetables provided the best printability and shape fidelity. 3D printing at …

Synthesis And Biophysical Analysis Of Modified Cell-Penetrating Peptides, Joel Mitchell

Theses and Dissertations (Comprehensive)

Cell-penetrating peptides (CPPs) are a family of peptides that have the ability to penetrate biological membranes. They were discovered in the late 1980s and have been the topic of many studies. Much of the interest in CPPs has been due to their ability to translocate biological membranes, and the possibility that they could offer a novel drug delivery method by conjugation to biologically active molecules. Linear CPPs can be modified to form cyclic structures. This change in structure has been observed to enhance the stability and penetrative ability of the CPPs which have been studied. The current thesis focuses on …

If Held Holds: Held V. Montana And The Future Of Constitutional Environmental Litigation, Leonora Owsley

SMU Science and Technology Law Review

The State of Montana is one of three states whose constitutions presently contain a “green amendment[.]” These amendments, enshrined in their respective Bills of Rights, protect a citizen’s fundamental right to a clean and healthy environment, ideally ensuring that the state’s government cannot infringe upon that right. However, following the green amendment’s adoption in 1972, Montana’s law still prioritized its extractive energy and hard rock mining industries over its citizens’ environmental rights. Now, that landscape is beginning to change. In 2011, Montana adopted an amended State Energy Policy Act, which expressly forbade its agencies from considering the effects of climate …

Variation In Mainland Northwest Territories Late-Winter Muskox (Ovibos Moschatus) Density Estimations And Habitat Associations Above And Below Treeline., Charlotte Rentmeister

Theses and Dissertations (Comprehensive)

The Arctic and Sub-Arctic ecosystems are seeing accelerated changes in temperature, landcover, and consequently species abundance and distributions. Reliable distributions, and associated population density estimates, are essential for effective conservation and management efforts. Growing concerns from northern communities regarding the relationship between muskox and declining caribou populations strengthens the need for updated information on muskox populations within mainland Northwest Territories (NWT). The first objective for my research was to quantify and map updated winter estimates of abundance, density, and distribution of muskoxen within three recent survey regions located in mainland NWT, using a multiple covariate distance sampling method (MCDS), paired …
