Medicinal Properties Of The Araliaceae, With Emphasis On Chemicals Affecting Nerve Cells, Rana Alharbi

Masters Theses

In recent times, medicinal plants have become the focus of scientists and research. However, many have used traditional medicine to take advantage of plant extracts to treat many diseases, especially neurological diseases. Various central nervous system receptors have been shown to associate with plant extracts influencing the pharmacology and in this manner conceivably assuming a role in human sickness and treatment. For instance, extracts from Cussonia paniculata Eckl. & Zeyh targeted several early nervous and mental disease, and Kalopanax pictus has been traditionally used for the treatment of rheumatoidal arthritis, nerve pain and diabetes mellitus.

In the present study, we …

Context Dependency Of Invasion Impacts On The Controllers Of Invasibility In Microstegium Vimineum, Scott Vincent Janis

Masters Theses

Although plant invasions are of major conservation concern, understanding of the natural controls on invasion and their impacts is largely limited to static observational studies or artificially manipulated systems. Linking patterns of invasion with subsequent impacts in natural systems is necessary to fully assess invasion causes and consequences. Therefore, I employed a long-term approach to sequentially assess the controls on invasion and their subsequent impacts in a self-assembled system for the highly invasive annual grass Microstegium vimineum. I modeled likely factors contributing to the probability of invasion and local invasion success of a natural invasion of M. vimineum in a …

Assessment And Recovery Of Stream Restoration Efforts On Fish Communities, Jessica Marie Rohr

Masters Theses

Aquatic systems are subjected to disturbances of various types, including natural and anthropogenic, or can deteriorate due to accumulating unfavorable conditions, including receding banks, decreasing riparian vegetation, and disrupted flow patterns. An analysis was done on a variety of streams in central Illinois that experienced one or multiple anthropogenic disturbances without remediation to determine the natural recovery dynamics of each system. A separate analysis was performed on a multi-site restored stream with a complex restoration project with a variety of restoration methods. This data were collected over at periods of time spanning from 5-15 years, including time prior to disturbance/restoration …

Identifying Priority Conservation Areas And Strategies For Myotis Sodalis (Chiroptera: Vespertilionidae) Via Habitat And Connectivity Modeling, Ashleigh B. Cable

Masters Theses

Myotis sodalis, the Indiana bat, is a federally endangered bat species in the United States of America (USA). Conservation efforts are typically focused at identified maternity sites at local scales, however, the species is a regional migrant that interacts with its environment at multiple spatial scales. We are limited in our knowledge of landscape-level requirements of this species, especially in large areas such as Illinois, USA, where a wide range of environmental and landscape conditions exist. Many previous M. sodalis habitat studies have limited their focus to smaller spatial scales. Due to limitations in funding, personnel, and time, it …

Evaluation Of Intra-Species Diversity Of Oxalobacter Formigenes Strains Using Pulsed-Field Gel Electrophoresis (Pfge) And Multiplex Pcr, Nivedita Pareek

Masters Theses

Oxalobacter formigenes is a beneficial, strict anaerobic gut bacterium that plays an important role in the prevention of kidney stone disease with a unique characteristic of using only oxalate as a carbon and energy source. To date, twenty-one strains of O. formigenes have been isolated which are further divided into two groups based on differences in the patterns of cell membrane lipids, cellular proteins, and nucleic acid fragments. The objective of the study was to evaluate intra-species diversity of O. formigenes strains using pulsed-field gel electrophoresis (PFGE) and multiplex PCR.

Nine pure cultures of O. formigenes strains (5 strains group …

An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine

Masters Theses

Large rivers are highly important systems; being exploited both commercially and recreationally. Because of this usage by humans, close monitoring of the ecology of theses rivers is of the utmost importance. The Long-Term Electrofishing project (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using day time, pulsed-DC electrofishing during the late Spring through the early Fall each year. Given that previous studies have noted diel and seasonal changes in catch and composition of fish communities, the addition of night time electrofishing may be beneficial to the overarching goals of the LTEF. This study sought to …

Xylan Metabolism By Caulobacter Crescentus, Viet Bui

Masters Theses

Bacteria present unique opportunities to explore the molecular mechanisms of nutrient acquisition processes at single cell level under various experimental conditions. Caulobacter crescentus is a gram-negative oligotrophic environmental bacterium with adaptive physiological responses, such as slow growth or complete arrest of cell cycle, presence of sessile and motile progenies with the sessile cells growing stalk to enhance nutrient uptake for growth in low-nutrient conditions. Details of plant polysaccharide-derived carbon compound, such as cellobiose, maltose, and xylose utilization by C. crescentus can be found but molecular details or mechanisms of polysaccharide utilization, such as xylan, has not been reported.

Farm To Label: A Critique Of Consumer Activism In The Sustainable Food Movement, Olivia Whitener

Pomona Senior Theses

“Local,” “organic,” “natural,” and “Fairtrade” are just several of the many claims adorning the food products that line grocery store shelves. These promises of environmental sustainability and social responsibility are pillars of the “good food revolution” sweeping the nation as consumers demand alternatives to the products of the industrial food system. Green consumerism, the premise that consumer demand for environmentally sustainable goods will bring about ecologically beneficial outcomes, is at the heart of the sustainable food movement. This thesis takes a critical look at the operation of green consumerism in the food system. It explores the ideology and shortcomings of …

Let's Get Sorted: The Path To Zero Waste At Pomona College, Sara Sherburne

Pomona Senior Theses

This senior thesis in environmental analysis explores the Zero Waste ideal and its practical application to a college campus. Given the growing global trash crisis and its grave environmental, social and economic consequences, the Zero Waste movement argues for a holistic shift from ‘end of pipe’ disposal practices to those that promote the cyclical use of materials, with little-to-no matter ending up in the landfill or incinerator. Cities and colleges around the world have adopted these Zero Waste goals in an effort to function as more sustainable, efficient and moral entities. With a case study of Pomona College, I assess …

In The Eye Of The Storm: Houston After Hurricane Harvey, Brandon Tolentino-Serrano

Pomona Senior Theses

Situated in one of the wettest climates in America, Houston, TX has had a long history of heavy rains and unprecedented floods. Unfortunately, floods have become more common over the last few decades as climate change increases the frequency and intensity of hurricanes around the globe. To complicate matters further, Houston has quickly sprawled to accommodate over 2.5 billion people. Rapid urbanization has rendered the landscape even more susceptible to floods through excess concretization and watershed disturbance. This thesis traces the history of the Bayou City in relation to the damages caused by Hurricane Harvey. By mapping out the original …

"But It's Not Fair!": Effects Of Experimenter Familiarity On Inequity Aversion In Dogs, Kia Radovanovic

Senior Independent Study Theses

Inequity aversion, defined as having a negative reaction to unfair treatment, was considered to be a uniquely human trait for decades but has since been found to exist in a variety of animals, including primates and dogs. Although dogs have been shown to be affected in their decision making based on their familiarity with the humans testing them, this effect had not been previously examined in regard to their responses to inequity aversion. This study aimed to partially replicate the results shown in the first ever study to find inequity aversion in dogs and to further investigate whether their responses …

Seagrass Ecosystems: A Career-Long Quest To Understand Their Inner Workings, Kenneth L. Heck Jr

Gulf and Caribbean Research

Four decades of research findings associates on the ecology of seagrasses and their animal and plant associates are described here, along with some of the major changes and advances that have taken place in our understanding of the inner workings of these amazingly productive and diverse ecosystems. Of primary importance are shifts in the recognition of: 1) the importance of the nursery role of seagrasses and how it can be quantified; 2) the importance of direct herbivory in the trophic ecology of seagrass-dominated ecosystems; and 3) the primacy of consumer effects in determining the abundance of algal epiphytes that colonize …

Developing Gold Nanoparticles-Conjugated Aflatoxin B1 Antifungal Strips, Tobiloba Sojinrin, Kangze Liu, Kan Wang, Daxiang Cui, Hugh Byrne, James Curtin, Furong Tian

Articles

Lateral flow immunochromatographic assays are a powerful diagnostic tool for point-of-care tests, based on their simplicity, specificity, and sensitivity. In this study, a rapid and sensitive gold nanoparticle (AuNP) immunochromatographic strip is produced for detecting aflatoxin B1 (AFB1) in suspicious fungi-contaminated food samples. The 10 nm AuNPs were encompassed by bovine serum albumin (BSA) and AFB1 antibody. Thin-layer chromatography, gel electrophoresis and nuclear magnetic resonance spectroscopy were employed for analysing the chemical complexes. Various concentrations of AFB1 antigen (0–16 ng/mL) were tested with AFB1 antibody–BSA–AuNPs (conjugated AuNPs) and then analysed by scanning electron microscopy, ultraviolet–visible spectroscopy, and Zetasizer. The results …

Some General Results On Fractional Banach Sets, Faruk Özger

Turkish Journal of Mathematics

The gamma function which is expressed by an improper integral is used to establish the fractional difference operators and fractional Banach sets. In this study, we achieve some comprehensive and complementary results related to characterizations of the matrix classes of fractional Banach sets. We also obtain some identities or inequalities for the Hausdorff measure of noncompactness of the corresponding matrix operators, and finally find the necessary and sufficient conditions for those matrix operators to be compact.

Bank Efficiency And Regional Economic Growth: Evidence From China, Hong Zhuang, Haiyan Yin, Miao Grace Wang, Jiawen Yang

Economics Faculty Research and Publications

This paper examines for the first time the relationship between bank efficiency and regional economic growth in China with provincial data over 1995 - 2014. We find consistent and strong evidence that bank efficiency positively affects regional economic growth. Further, bank efficiency exerts a more pronounced impact on economic growth in inland provinces than coastal regions. The insignificant effect of the quantity of credit in our regressions suggests that a mere expansion of financial volume is not effective in promoting regional economic growth, whereas the improvement in the quality of financial intermediation plays an important role fostering provincial economic growth.

Alfred Russel Wallace Notes 9: The South Asian Connection, Charles H. Smith, Sahotra Sarkar, Nirmali Wijegoonawardana

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) is best known for his natural history explorations and theoretical biology, but he was also a potent social critic on subjects ranging from land tenure and colonial policy to antivaccinationism and poverty. Here, one of his emphases in the latter domain is spotlighted: his interest in South Asian affairs. This extended to a variety of subjects in the areas of politics, economics, health, literature, sociology, etc., and to a degree that may have had some influence on the development of thought of some major South Asian figures, including Mahatma Gandhi and Ananda K. Coomaraswamy.

Neuroscience, Artificial Intelligence, And The Case Against Solitary Confinement, Francis X. Shen

Vanderbilt Journal of Entertainment & Technology Law

Prolonged solitary confinement remains in widespread use in the United States despite many legal challenges. A difficulty when making the legal case against solitary confinement is proffering sufficiently systematic and precise evidence of the detrimental effects of the practice on inmates' mental health. Given this need for further evidence, this Article explores how neuroscience and artificial intelligence (AI) might provide new evidence of the effects of solitary confinement on the human brain.

This Article argues that both neuroscience and AI are promising in their potential ability to present courts with new types of evidence on the effects of solitary confinement …

In the following decades, AI will continue to transform more fields and deliver astonishing advancements in convenience, comfort, safety, and security. At the same time, however, AI will bring about new challenges. AI will offend, disrupt, crash, breach, incite, injure, and even kill …

Please Don't Stop The Music: Using The Takings Clause To Protect Inmates' Digital Music, Amber M. Banks

Vanderbilt Journal of Entertainment & Technology Law

In prisons across the country, inmates are encouraged to participate in digital media programs. One in ten correctional facilities in the US has digital media programs in which inmates purchase both a device-such as an MP3 player or tablet-and content or services for the device-such as digital music-from a third-party vendor. Although fee structures vary, the facility or the state corrections department usually receives a commission on the revenue generated from inmates' purchases, thereby profiting off of each purchase that an inmate makes. As their contracts with third-party vendors end, state correctional departments may change vendors, either in search of …

Video Games In The Twenty-First Century: Parallels Between Loot Boxes And Gambling Create An Urgent Need For Regulatory Action, Alexandra M. Prati

Vanderbilt Journal of Entertainment & Technology Law

A loot box is a purchasable in-game digital container holding randomized virtual rewards. In recent years, loot boxes have become increasingly common in video games. A large number of major video game titles now incorporate loot boxes, and loot box sales now eclipse traditional game sales as the primary source of revenue for much of the video game industry. Given that more than half of teenagers play video games for several hours each day, the growth of loot boxes has sparked a contentious debate over whether loot boxes constitute a form of unregulated gambling targeted at children. This Note contributes …
