Squash, Brianne Sherwood, Sara Hunt, Crista Sorenson, Bethany Heineman, Blake Beyers, Ashley Walker Workman

USU Student Organic Farm Newsletter

It is generally accepted that the squash plant is native to the Americas. Remains have been found in Central America and Mexico dating back as far as 7000 BC. From its southern origin, squash spread throughout North America. The name squash is apparently derived from the Algonquin "askoot asquash", meaning "eaten green". The plant found its way to Europe when the early explorers retumed home.

Do Psychology Researchers Tell It Like It Is? A Microgenetic Analysis Of Research Strategies And Self-Report Accuracy, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Acquiring research skills is considered to be a highly challenging aspect of developing expertise in the social sciences. Because instruction and mentoring in these skills are typically grounded in the self-report of researchers, difficulties in learning the material may be due to the content and accuracy of these explanations. Using a mixed-method, microgenetic design, this study examines the explanations of problem-solving processes by researchers along a continuum of expertise during simulated experiment design and subsequent data analysis. Findings indicate that participants’ self-explanations are largely inaccurate. Further, frequency of inaccurate statements is positively associated with the frequency of abstract cognitive processes, …

Parsley, Brianne Sherwood, Sara Hunt, Crista Sorenson, Bethany Heineman, Blake Beyers, Ashley Walker Workman

USU Student Organic Farm Newsletter

Parsley is native to the Mediterranean region of Southern Europe. While it has been cultivated for more than 3000 years, parsley was used medicinally prior to being consumed as a food. The ancient Greeks held parsley to be sacred, using it to not only adorn victors of athletic contests, but also for decorating the tombs of the deceased. While it is uncertain when parsley began to be consumed as a seasoning, it seems to be sometime in the Middle Ages in Europe. Parsley is a key ingredient in several West Asian salads, e.g., tabbouleh which is the national dish of …

A Prototype Miniaturized Metabolic Gas Analysis Sensor, Tammy Anderson, Joseph Orr

Utah Space Grant Consortium

Microgravity adversely affects several physiological systems. As space exploration moves to extended flights, understanding which mechanisms microgravity influences may contribute to the health and safety of astronauts aboard. Maximum oxygen consumption (VO₂ max) testing is used to monitor changes to cardiorespiratory function. Currently the equipment used to such testing aboard the International Space Station (ISS) is large and requires a significant amount of power. We propose the use of a modified metabolic management system, currently approved for clinical use, for exercise stress testing.

Comparative Performance Of Fluorometry And High Performance Liquid Chromatography In The Detection Of Aflatoxin M1 In Two Commercial Cheeses, Gustavo Peña

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aflatoxin M1 (AFM₁) is frequently found in milk and dairy products. It is a metabolite formed in cows from aflatoxin B1 (AFB₁), contained in animal feeds. In cheese production AFM₁ distributes between curds and whey. In this study, cows were fed 64 µg/AFB₁/d for the high treatment, and 5 µg/AFB₁/d for the low treatment, to obtain milk contaminated with AFM1 over the 0.5 µg/L and under 0.05 µg/L restrictions, respectively. Cheese was manufactured with milk contaminated with AFM₁ at 0.8 and 0.03 ìg/kg by the higher and lower …

Altering Functional Properties Of Fats Using Power Ultrasound, A. H. Suzuki, J. Lee, S. G. Padilla, Silvana Martini

Nutrition, Dietetics, and Food Sciences Faculty Publications

Ultrasound has been used for the last 50 y in different processing applications. Depending on the power and frequency of the sound waves, ultrasound techniques can be classified in different categories. Low-intensity ultrasound uses high frequencies in the range of 100 kHz to 10 MHz and is mostly used for therapeutic purpose (frequencies between 1 and 10 MHz) and to passively monitor the characteristics of materials (frequencies between 100 kHz and 10 MHz). High-intensity ultrasound (HIU), on the other hand, uses lower frequencies in the range of 20 to 100 kHz and it is commonly used for cleaning, disrupting, and …

Weight Discrimination: Why Current Perceptions Need To Change, Kelsey Rae Eller

Undergraduate Honors Capstone Projects

Discrimination based on weight has been labeled the last form of socially acceptable prejudice. Weight discrimination is becoming more and more prevalent in schools, the workplace, social settings, the media, and even in healthcare. Overweight and obese individuals are often stereotyped as lazy, addicted to food, and lacking self-discipline and initiative, and as a result may struggle with decreased employment opportunities, fear and shame in public, attempting dangerous weight loss methods, or even eating disorders.

This project seeks to identify and examine research that has been done on this subject in order to increase awareness of weight bias and to …

An Investigation Of Dietary Supplementation As A Potential Source Of Nutrition Misinformation Hindering The Development Of Healthy Eating Habits In The College Population, Mary Dimmick

Undergraduate Honors Capstone Projects

Current dietary supplement legislation allows nutrition misinformation to flourish; misleading structure‐function and health‐claims now abound on supplement labels. Meanwhile, college students tend to be open to experimentation and exploration. Hence, this study’s objective was to discover if students at USU are being influenced by such claims to unjustifiably take dietary supplements in a manner which hinders the development of healthy eating habits. During August of 2009, 1,300 USU freshmen were invited to voluntarily participate in an on‐line survey concerning dietary patterns which included a section about dietary supplementation. Five‐hundred‐and‐twelve completed the survey after providing informed written consent to participate. The …

Acyl Homoserine Lactone Signaling In Pseudomonas Chlororaphis 06, Anna Hegsted

Undergraduate Honors Capstone Projects

Pseudomonas chlororaphis (PcO6), a rhizosphere bacterium, is important to agriculture because of its use as a biological control against fungus and other pests. This biological control correlates with production of phenazines; a process regulated by acyl homoserine lactones (AHSLs). Long chain AHSLs might also have an affect on the production of phenazines. My research showed that PcO6 produced long chain AHSLs and that production is affected by nutrition with more long chain AHSLs produced in rich medium than minimal medium. The nutritional studies and findings with different mutants of PcO6 altered in phenazine production suggest that control of these antifungal …

Significant Interactions With The Most Commonly Used Herbal And Nonherbal Supplements Impact Warfarin Safety And Efficacy, Brittany Jean Sagers

Undergraduate Honors Capstone Projects

Background: Nearly 20% of adult Americans used herbal therapies in 2007, but greater than two-thirds failed to report such use to their medical provider. Significant patient harm may occur when herbal supplements are taken in conjunction with warfarin; however, patients and medical providers may not be aware of these interactions and this may place patients at risk for life-threatening bleeds or thrombotic complications.

Methods: The authors determined the top 25 herbal and 25 nonherbal supplements used by Americans using sales data from 2008, and each product was reviewed for its potential to interact with warfarin. Electronic searches were conducted using …

To What Extent Do Local Farmers' Markets, Community Supported Agriculture Programs, And Community Gardens Help Low-Income Families Improve Access To Fresh, Local Produce?, Christy Gene Somsen

Undergraduate Honors Capstone Projects

Farmers’ Markets, Community Supported Agriculture (CSA) Programs, and Community Gardens have been developed to help farmers. Many times, they also aim to help low-income families improve access to fresh produce. Often, these programs may end up helping a larger amount of middle class families instead of lower class families. There have been many programs developed to try to better help low-income families such as the Women Infant and Children (WIC) Farmers’ Market Nutrition Program (FMNP) and allowing farmers to accept WIC Cash Value Vouchers (CVV), which allows WIC participants to buy fresh produce.

Optimizing The Physical And Nutritional Environment Of Unleached Root-Zones, Curtis B. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Unleached root-zones represent an environmental ideal by eliminating wasteful leaching of nutrients and water. NASA grows plants in space in unleached root-zones, incorporating polymer-coated fertilizer (PCF) into a ceramic media (Turface or Profile). However, lack of growth productivity in space has led to the need for research to improve the nutritional and physical environment of the root-zone, which is the objective of this research. PCF types are diverse in release characteristics and the effects of temperature and substrate water content have not been well characterized. In spite of widespread use, studies on chemical properties and applied studies to verify soil …

Thousands of unique isolates of Metarhizium exist throughout the world. These isolates vary widely in their ability to cause infection and to tolerate stressful habitats. The research reported here tests the THESIS: A laboratory-based system can be devised that identifies, from among many Metarhizium isolates, those isolates with the greatest potential for successful biological control of pest insects …

Development Of Novel Methods And Their Utilization In The Analysis Of The Effect Of The N-Terminus Of Human Protein Arginine Methyltransferase 1 Variant 1 On Enzymatic Activity, Protein-Protein Interactions, And Substrate Specificity, Brenda Bienka Suh-Lailam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein arginine methyltransferases (PRMTs) are enzymes that catalyze the methylation of protein arginine residues, resulting in the formation of monomethylarginine, and/or asymmetric or symmetric dimethylarginines. Although understanding of the PRMTs has grown rapidly over the last few years, several challenges still remain in the PRMT field. Here, we describe the development of two techniques that will be very useful in investigating PRMT regulation, small molecule inhibition, oligomerization, protein-protein interaction, and substrate specificity, which will ultimately lead to the advancement of the PRMT field. Studies have shown that having an N-terminal tag can influence enzyme activity and substrate specificity. The first …
