Dietary Supplementation in Lambs: Evaluating the Effects of Depth Charge on Meat Composition
No full textOften, animals destined for consumption are fed supplements to help speed up or slow down their growth rate, enhance aesthetics, or standardize the product. Herein, we examined the supplement Depth Charge and its effects on the fat and protein content in lambs of the same age and lineage. Depth Charge increases fiber consumption to add spring of rib or an outward rib cage curvature to an animal\u27s appearance while restricting feed consumption. Since the supplement targets the rib-loin area, we chose to analyze loin chop, loin roast, and hamburger cuts from each lamb and conducted experiments to determine how each was affected. Protein content was determined using a RIPA buffer to lyse the cells, followed by a Bradford assay, while fat content was obtained through a tallow rendering method. The hamburger cut serves as an internal standard, representing a mixture from various body regions, while the loin chop and loin roast provide a more concentrated look at the targeted areas. This study aims to quantify the impacts of Depth Charge on meat composition to better understand the connection between dietary supplementation and livestock production

The Perfect Embouchure
No full textWhen describing an embouchure most brass players think only about the feeling of the mouth and face, and not about what muscles to engage. Unfortunately, a lack of knowledge in this area can lead to overuse of muscles in the face and serious injury. A musical outcome is that over tightening of muscles in the face and body can lead to a tense, bright sound, instead of a dark, warm sound. My research aims to provide better information about what muscles are needed to function when playing rather than tensing the whole face, allowing for better air flow and control of the instrument, and avoiding injury. My research uses available MRIs and lip cameras to observe the muscles used in order to play a brass instrument, how those muscles interact with each other, and how to engage those muscles properly. I also explore the relationship between an effective embouchure and an effective aperture (the lips affecting the hole the air flows through). Through my close study of these physical elements, I hope to find the (almost) perfect embrouchure so pedagogues can teach young students more effectively or can develop long term healthy playing habits in their young students

Investigating the Efficacy of Mebendazole on C. elegans: Implications for Anthelmintic Drug Development
No full textAbout 1.5 billion people in the world are infected with soil-transmitted helminths, especially those who live in high poverty areas. These infections affect communities with poor access to clean water, sanitation and hygiene in tropical and subtropical areas, keeping them in a state of poverty. Our research focuses on drugs that target the parasitic worms currently approved by the World Health Organization (WHO). The WHO currently only has 4 approved drugs for Mass Drug Administration, due to low profit margins, complex parasite life cycles, and rising drug resistance (World Health Organization 2023). While Mebendazole is effective against many common parasitic worms, its effectiveness can vary by species and individuals who are affected. C. elegans, a free living nematode, are used as a model organism of parasitic worms as they are very similar (in the same phylum) and have a long, well-documented history in research due to their minimal nutritional needs, making them easier to maintain, their large progeny via self-fertilization, and their small size. Additionally, C. elegans life cycle is typically 14-21 days, or 1 to 2 weeks after egg-laying, providing a convenient time frame for research (Dahlberg et al. 9). Our research is trying to elucidate the effectiveness of Mebendazole at varying concentrations, in the L4 lifestage of C. elegans. This allows for further analysis and determination of the efficacy of Mebendazole to better confirm its treatment effects. The findings in our research has shown that the health of the worm decreases in a dose dependent manner
Middle Tennessee Rhetoric about Immigration
No full textNashville is home to a growing and diverse immigrant population, contributing significantly to the city’s cultural, social, and economic landscape. Despite this, immigrants in Nashville often face systemic undervaluation, as reflected in policies prevailing public rhetoric. For example, recent proposals suggest that undocumented students may lose access to public education, even while many immigrant students already face barriers to receiving specialized support due to language differences. These issues are not isolated but part of a broader context of anti-immigrant sentiment, which has far-reaching implications for educational equity and public policy. Words shape beliefs, and beliefs influence actions. The rhetoric used to discuss immigration plays a critical role in shaping public sentiment and, in turn, the policies that govern immigrant lives. This qualitative study consists of interviews with local education advocates, administrators, experts, and other leaders who work directly with immigrants or on issues affecting immigrant students. Interviews were analyzed with a constant comparative approach and using a thematic coding structure. Major themes include the impact of rhetoric on student wellbeing, rhetorical devices used in discussing immigration, and the polarizing climate surrounding this topic
Exploring the Effects of Indoor Plants on Executive Function
No full textThe link between greenery in schools and cognitive performance is underexplored, even with evidence of its benefits in other settings. Research indicates that adding green plants to an office can improve mood and lower stress (Bergefurts et al., 2021). This study explored the factors behind the psychological benefits of indoor plants on executive function in college students. The study proposed two competing hypotheses based on Attention Restoration Theory (ART) and Enrichment Theory. The study is a 2x2 between-subjects factorial design, in which participants were exposed to environments with or without plants and with or without organizational enrichment. Participants were undergraduate and graduate students 18 years or older. Executive function was measured using the Sustained Attention to Response Task (SART), while mood was measured using the Positive and Negative Affect Schedule (PANAS). To measure Enrichment, the study used a modified Nieuwenhuis questionnaire. Separate Repeated Measures ANOVAs were used to analyze accuracy and reaction time (RT) differences from the SART across conditions and time. There was no significant main effect of time, condition, or time by condition interaction. The same results were found for Reaction Time. Results show no significant effect of plant presence or workspace organization on executive function as measured by SART task performance. Regarding enrichment, participants reported perceived levels of Fatigue, Concentration Problems, Decreased Motivation, and Physical Activity after tasks 1 and 2. A One-Way ANOVA revealed no differences at T1 for all four indicators. Similar results were found at T2, except that there was a significant effect of condition on motivation at T2
Message in a Bottle
No full textIn her poetry collection “Message in a Bottle”, Ellie Harwood explores the relationships we maintain with each other, animals, and nature. Through the poems in this collection, Harwood examines how we as humans simultaneously harm one another and our fragile ecosystem while seeking love and belonging in those very relationships and spaces. By contrasting the evolutionary journey of whales with the rampant development of technology in the poem “Whale Song”, or through portraying the desire to flee from somebody you love deeply in “Bedhead”, Harwood highlights the many contradictions and conflicts that come with being alive (and the numerous ways we either reconcile or disregard them), as well as the obstacles we face in embodying our human compassion
A Quest for Identity
No full textIn The Absolutely True Diary of a Part-Time Indian, Sherman Alexie delves into the story of an adolescent boy growing up on an Indian reservation, wrestling with hard medical issues and the typical emotional turmoil associated with coming of age. Arnold, who goes by Junior, also faces complex issues such as racism, less-than-ideal family relationships, and identity. Alexie approaches Arnold’s experiences with humor and storytelling that can only be found in the genre of young adult literature. This paper finds Alexie’s notion of identity construction as an unstable, shifting process often shaped by the opinions of others. The structure of Alexie’s young narrative voice portrays the common shifts in identity that occur in the teenage years. Through images and narration, Alexie highlights the identity fragmentation that can occur in an indigenous teenager navigating white spaces. Through his narrative choices, images, and humor, Alexie affirms that indigenous identity construction is both supported and fragmented by the views of the dominant culture
