Faculty, Staff and Students Publications

Osteosarcoma is the most frequent primary malignant bone tumor with an annual incidence of about 400 cases in the United States. Osteosarcoma primarily metastasizes to the lungs, where FAS ligand (FASL) is constitutively expressed. The interaction of FASL and its cell surface receptor, FAS, triggers apoptosis in normal cells; however, this function is altered in cancer cells. DNA methylation has previously been explored as a mechanism for altering FAS expression, but no variability was identified in the CpG island (CGI) overlapping the promoter. Analysis of an expanded region, including CGI shores and shelves, revealed high variability in the methylation of …

The “Best Test” For Success In Academic Advising: Exploring The Purpose Of Advising Through The Lens Of Servant-Leadership., Jeffrey Mcclellan

Servant Leadership: Theory & Practice

For years, advising has been associated with student success and retention. However, while these are valuable byproducts of effective academic advising, they do not represent the purpose of advising. This article explores the purpose of academic advising through the lens of servant-leadership theory with an emphasis on Greenleaf’s (2002) best test, which asks, “Do those served grow as persons? Do they, while being served, become healthier, wiser, freer, more autonomous, more likely themselves to become servants?” (p. 27). The outcomes alluded to in this statement are examined and explored as they relate to the purpose of academic advising and student …

An Unsung American Hero: A Case Study Of Frances Perkins's Servant-Leadership And Its Modern Impact, Jeffrey Coats

Servant Leadership: Theory & Practice

Francis Perkins was one of the most influential servant-leaders of the 20th Century and may be considered an “unsung hero” for her trailblazing efforts to help marginalized groups: the poor, senior citizens, laborers, the unemployed and children. So much of American’s daily lives and what millions of Americans utilize and depend upon (e.g. a 40-hour workweek, overtime pay, unemployment insurance) is a direct result of her life’s work. Yet, she has often been omitted from History books and many Americans may have never heard of her. This article examines her servant-leadership characteristics and the actions that resulted from her being …

The Relevance And Benefits Of Moral Intelligence To Servant Leadership, Kong Wah Cora Chan

Servant Leadership: Theory & Practice

Moral intelligence has a better chance of fixing morality-related issues instead of bandaging them and addressing the servant leadership best test stated by Greenleaf (1977/2002). Prudence—mature moral intelligence—is one’s skillful act in making the best, most caring alternative among all possible choices based on moral wisdom (Bradshaw, 2010). Morally intelligent people are conscious of aligning their values, goals, and actions with the universal principles of integrity, responsibility, compassion, and forgiveness (Lennick and Kiel, 2011). Such an alignment leads to purposeful living and organizational success. Borba (2001) advocated for building moral habits of empathy, conscience, self-control, respect, kindness, tolerance, and fairness. …

Servant Leadership And Violent Extremism: An Evaluative Framework, Eric J. Russell, Ardian Shajkovci

Servant Leadership: Theory & Practice

The following article presents a conceptual servant leadership framework for evaluating preventing violent extremism (PVE) policies and programs. The purpose of the work was to discover how servant leadership could strengthen existing PVE evaluative strategies. This article stems from work being done in servant leadership, counterterrorism, and countering violent extremism at Nichols College and Utah Valley University. The authors used a secondary analysis of empirical and literary servant leadership and PVE works to develop the framework. The analysis revealed a relationship between servant leadership’s commitment to the growth of people and building community and the need for PVE to be …

Analysis Of Biologically Active Secondary Metabolites From Fungi, Elizabeth E. Guevara, Kirk Manfredi

Summer Undergraduate Research Program (SURP) Symposium

Fungi produce secondary metabolites, which are organic compounds that allow the organism to be competitive in their environment. Secondary metabolites are not involved in growth and development, instead they affect ecological interactions to increase survivability. These compounds will often have antimicrobial properties, leading to their use in antibiotics. Isolating a compound with significant antimicrobial activity could lead to its use in therapeutic antibiotics. New antibiotics are needed to address the growing issue of antimicrobial resistant bacteria. This project explores the antimicrobial compounds produced by fungi collected Wind Cave National Park or carried by local insects. Accurate taxonomic identification of the …

Synthesis And Reactivity Of Dihydrogen Diruthenium Complexes., Ryder J. Downey, Robert Chin

Summer Undergraduate Research Program (SURP) Symposium

Having two open coordination sites on the diruthenium complex makes for the ability to be able to be more precise when interacting with other compound. The side-on bonding of the bis(dihydrogen) gives it unique characteristics as well as unique capabilities. The Oganotransition Metal Chemistry book says that the dihydrogen is bonded by the donation of electrons from the H-H sigma bond as well as the back donation of electron density through the transition metal.3

In the past, many groups have studies on a mononuclear Ruthenium compound similar to the one we are synthesizing (see figure one). Our goal was to …

Functional Analysis Of Spermidine Synthase (Spds) Using Virus-Induced Gene Silencing In Barley, Ammar A. Shaikh, Tilahun Abebe

Summer Undergraduate Research Program (SURP) Symposium

Polyamines are low molecular weight aliphatic nitrogenous compounds with two or more amino groups (Liu et al., 2015). Polyamines are found in all organisms. They play diverse roles in growth and development as well as environmental stress response. One of the major polyamines in plants is spermidine. Spermidine increases grain filling by increasing hormones and enzymes in sucrose biosynthesis (Luo et al., 2019). Expression of genes in the spermidine biosynthesis pathway increases during drought in barley (Abebe et al., 2010). However, the role of spermidine biosynthesis for drought tolerance has not been systematically investigated in barley. In the past, we …

Analysis Of The Role Of Gamma-Aminobutyrate (Gaba) In Drought Tolerance In Barley Using Virus-Induced Gene Silencing, Thomas Manternach, Tilahun Abebe

Summer Undergraduate Research Program (SURP) Symposium

Gamma-aminobutyric acid (GABA) is a messenger in cellular communication. As GABA is also an enhancer in stress tolerance, this often leads to rapid accumulation during drought. . GABA increases photosynthesis and reduces water loss through the stomata (Li et al., 2021; Xu et al., 2021). The metabolization of GABA occurs via the GABA shunt, which is produced primarily from a glutamic acid catalyzed by glutamate decarboxylase (GAD) in the cytosol. GABA is imported into the mitochondria and subsequently degraded by GABA-transaminase (GABA-T) into succinic semialdehyde (SSA) . In barley, both GABA and GAD genes are induced during drought (Abebe et …

Geometric Curves From P-Circles, Isaiah Dempsey, Bill Wood

Summer Undergraduate Research Program (SURP) Symposium

p-Circles are a generalization of the usual circle satisfying the equation |x|^p + |y|^p = 1. The 1-circle is the square with vertices (1,0),(0,1),(-1,0),(0,-1). As p goes to infinity the p-circle equation becomes max(|x|, |y|) = 1. So the ∞-circle is the square with vertices (1,1),(-1,1),(-1,-1),(1,-1). From 1≤p≤2 the p-circle smoothly transforms from a square to a circle, and from 2≤p≤∞ the p-circle smoothly transforms from a circle to a square.

Comparison Of Gut And Leg Pollen Composition In Female Halictus Ligatus With Flower Source, Sriya Kalala, Ai Wen

Summer Undergraduate Research Program (SURP) Symposium

It is commonly believed by bee biologists that wild bees visit one single flower species during each trip to make nest provision. However, the exact foraging behavior is not clear and may vary in different species of bees, and therefore the pollination patterns have continued to be studied. When a bee undergoes the process of pollination, the majority of the pollen consumed by the bee passes through the digestive tract and remains undigested. However, when the pollen is digested and used as an energy source, the pollen grain digestion occurs in the midgut intestine within the bee instead of the …

Forming A Comprehensive Pollen Library For The Purpose Of Native Bee Pollen Identification And Analysis, Madeline Roubik, Ai Wen

Summer Undergraduate Research Program (SURP) Symposium

The Iowa prairie is home to many species of bees who collect pollen for nutrition or nesting purposes (Real, 1983). Most bees collect pollen in their scopa, a small pollen collection pouch on their back legs or abdomen. However, the entire bee, including their thorax, can come in contact with pollen. Because of this, it is assumed that a bee’s pollen collection will be more diverse on its thorax where it unintentionally comes into contact with pollen, than its legs where it intentionally collects pollen. In this study, we created a comprehensive pollen library of native Iowa prairie flowers, and …

Investigating Gene Looping In Yeast, Abbie Bangs, Justin Peters

Summer Undergraduate Research Program (SURP) Symposium

Saccharomyces cerevisiae, also known as brewer’s yeast, is the model organism we chose to interrogate a possible length dependence of gene looping. Gene looping occurs when the promoter and the terminator regions of a gene come together in a physical interaction to form a loop. RNA polymerase transcribes the gene at an amplified rate due to the gene loop (Figure 1), but little research exists as to what factors are important for this process, including the mechanics of the underlying DNA.

Molybdenum Disulfide (Mos₂) As A Nanocellulose Substrate, Mariana Torres, Dylan Seiffert, Elise Hong-Miller, T. E. Kidd

Summer Undergraduate Research Program (SURP) Symposium

Cellulose is a substance abundant in nature, found in fruits and vegetables, plant cell walls (National Center for Biotechnology Information, 2023), and wood (Sjostrom, 1993). The abundance of cellulose is attributable to its linear chemical structure, as it is composed of long strands of glucose molecules linked together by hydrogen atoms, which enable the substance to withstand significant pressure without breaking (Rongpipi et al., 2019). This property—known as high tensile strength—is joined by its non-toxicity and sustainability, given cellulose may be degraded and renewed naturally (Kaur, 2021). These various properties indicate versatility, and its resultant current and desired uses—such as …

Flow Through Processing Of Nanocellulose For Space Exploration Applications, Dylan Seiffert, T. E. Kidd

Summer Undergraduate Research Program (SURP) Symposium

Nanocellulose is synthesized from cellulose, which is the most abundant organic molecule found in nature. Nanocellulose solids are biodegradable and have a strength-to-weight ratio eight times that of steel¹. The production of nanocellulose solids is challenging due to the large volume loss that occurs during the curing process as well as the time and cost associated with ultrasonic processing. The loss of volume during curing often results in cracking and deformation of the cured solid. The issues caused by the large volume loss can be mitigated using additives that do not compromise the strength, shape, or machineability of …

Impacts And Applications Of Vegetable Glycerin On Nanocellulose, Elise Hong-Miller, Dylan Seiffert, T. E. Kidd

Summer Undergraduate Research Program (SURP) Symposium

Nanocellulose is created by breaking down cellulose, the most common organic molecule found in nature. Nanocellulose has attractive properties, such as a very high strength-to-weight ratio, for many different applications. A major challenge is that nanocellulose has a very high shrinkage % (~90%) when it is dried, as well as a strong probability to crack. Different additives can be added in varying amounts to either mitigate or intensify these aspects, as well as affect its drying conditions. This investigation is helping the National Aeronautics and Space Administration (NASA) and the U.S. Army to find a use for this highly renewable …

Investigation Of A Magnet Falling Through A Copper Pipe, Brianna Williams, Paul M. Shand

Summer Undergraduate Research Program (SURP) Symposium

• The goal of this research is to explore the effects of wall thickness and temperature on the rate at which a magnet falls through a copper pipe.
• A magnet is not attracted to copper. Copper is not magnetic; however, it is a great conductor of electricity.
• Due to Faraday’s law and Lenz’s law, we know that a changing magnetic flux will produce an electric current that opposes the change in magnetic flux that produced it. These laws together explain why a magnet will fall slowly in a copper pipe even though it is not attracted.
