Effects Of Nitrogen And Phosphorus Additions On Nitrous Oxide Emission In A Nitrogen-Rich And Two Nitrogen-Limited Tropical Forests, Mianhai H. Zheng, Tao Zhang, Lei Li, Weixing X. Zhu, Wei Zhang, Jiangming M. Mo

Biological Sciences Faculty Scholarship

Nitrogen (N) deposition is generally considered to increase soil nitrous oxide (N2O) emission in N-rich forests. In many tropical forests, however, elevated N deposition has caused soil N enrichment and further phosphorus (P) deficiency, and the interaction of N and P to control soil N2O emission remains poorly understood, particularly in forests with different soil N status. In this study, we examined the effects of N and P additions on soil N2O emission in an N-rich old-growth forest and two N-limited younger forests (a mixed and a pine forest) in southern China to test the following hypotheses: (1) soil N2O …

High Throughput Genomic Sequencing Of Bioaerosols In Broiler Chicken Production Facilities, Kate M. O’Brien, Michael S. Chimenti, Morgan Farnell, Tom Tabler, Thomas Bair, Joey Lynn Bray, Matthew W. Nonnenmann

Faculty Publications

Chronic inhalation exposure to agricultural dust promotes the development of chronic respiratory diseases among poultry workers. Poultry dust is composed of dander, chicken feed, litter bedding and microbes. However, the microbial composition and abundance has not been fully elucidated. Genomic DNA was extracted from settled dust and personal inhalable dust collected while performing litter sampling or mortality collection tasks. DNA libraries were sequenced using a paired-end sequencing-by-synthesis approach on an Illumina HiSeq 2500. Sequencing data showed that poultry dust is predominantly composed of bacteria (64–67%) with a small quantity of avian, human and feed DNA (< 2% of total reads). Staphylococcus sp. AL1, Salinicoccus carnicancri and Lactobacillus crispatus were the most abundant bacterial species in personal exposure samples of inhalable dust. Settled dust had a moderate relative abundance of these species as well as Staphylococcus lentus and Lactobacillus salivarius. There was a statistical difference between the microbial composition of aerosolized and settled dust. Unlike settled dust composition, aerosolized dust composition had little variance between samples. These data provide an extensive analysis of the microbial composition and relative abundance in personal inhalable poultry dust and settled poultry dust.

A Comparative Study Of The Flora And Soils Of Great Duck And Little Duck Islands, Maine, Usa, Luka Negoita, Matthew Dickinson, Glen Mittelhauser, Nishanta Rajakaruna

Faculty Publications, Biological Sciences

Strong environmental gradients and varied land-use practices have generated a mosaic of habitats harboring distinct plant communities on islands on the coast of Maine. Botanical studies of Maine's islands, however, are generally limited in number and scope. Baseline studies of Maine's islands are necessary for assessing vegetation dynamics and changes in habitat conditions in relation to environmental impacts imposed by climate change, rising sea levels, invasive species, pests and pathogens, introduced herbivores, and human disturbance. We conducted a survey of the vascular plants and soils of forest, field, and ocean-side communities of Great Duck and Little Duck Islands, ME. These …

Prevention Strategies And Mental Health In Vietnam, Edward Cohen

Faculty Publications

This paper addresses the current state of mental health services in Vietnam and provides recommendations for improving the care of people with mental illness. Vietnam’s mental health problems are as prevalent as anywhere else in the world. The country has recently begun an initiative to reform mental health care by improving community-based services for people with serious mental illness. However, mental illness has not been a part of public discourse in Vietnam. There is little recognition of prevalent common mental illnesses (such as depression, anxiety and alcohol abuse) and the care of people with serious mental illnesses relies on either …

Limestone Flora Of The Simonton Corner Quarry Preserve, Rockport, Maine, Usa, Margaret Stern, Ian Medeiros, Luka Negoita, Nishanta Rajakaruna

Faculty Publications, Biological Sciences

Limestone is a distinctive substrate that has significant effects on soils and plants. The present study characterizes the diversity of vascular plants, bryophytes, and lichens at the Simonton Corner Quarry Preserve, an abandoned limestone quarry in Rockport, Maine, USA, which was in operation in the late 1800s. We document vascular plant diversity and associated edaphic features (i.e., soil pH and elemental chemistry) using 30 5×5 meter plots spread throughout the site. For vascular plants, 114 species in 96 genera and 50 families were observed; few of these species are known to prefer calcareous environments, and 38% are nonnative. Conversely, the …

Functionalized Cationic [4]Helicenes With Unique Tuning Of Absorption, Fluorescence And Chiroptical Properties Up To The Far-Red Range, I. Hernández Delgado, S. Pascal, A. Wallabregue, R. Duwald, C. Besnard, L. Guénée, C. Nançoz, E. Vauthey, R. Tovar, J. Lunkley, Gilles Muller, J. Lacour

Faculty Publications, Chemistry

Unprecedented regioselective post-functionalization of racemic and enantiopure cationic diaza [4]helicenes is afforded. The peripheral auxochrome substituents allow a general tuning of the electrochemical, photophysical and chiroptical properties of the helical dyes (26 examples). For instance, electronic absorption and circular dichroism are modulated from the orange to near-infrared spectral range (575–750 nm), fluorescence quantum efficiency is enhanced up to 0.55 (631 nm) and circularly polarized luminescence is recorded in the red (|glum| ∼ 10−3).

Species Interactions In Constructed Wetlands Result In Population Sinks For Wood Frogs (Lithobates Sylvaticus) While Benefitting Eastern Newts (Notophthalmus Viridescens), Chelsea S. Kross, Stephen C. Richter

Biological Sciences Faculty and Staff Research

Wetland construction has been used as a tool to mitigate wetland loss, but constructed wetlands might not provide the same functions as natural wetlands. Hundreds of long-hydroperiod wetlands have been constructed within the Daniel Boone National Forest, Kentucky, in a ridge-top ecosystem where natural wetlands dry annually (i.e., have short hydroperiods). The constructed wetlands have been colonized by several amphibian species not historically associated with this ecosystem and that could have negative impacts on native amphibian species. We compared wood frog (Lithobates sylvaticus) reproductive success at constructed and natural wetlands and benefits of wood frog presence in constructed wetlands to …

Examining The Lived Experiences Of Families Who Have Adopted Children And Received Occupational Therapy Services, David Simpson

Online Theses and Dissertations

Purpose: This qualitative descriptive study focused on the experiences of families who have adopted children from different countries and placed them in occupational therapy services.

Method: Three different sets of parents were interviewed to gather data on the adoption process and on their experiences with receiving services from an OT. Each interview was conducted either with one or both parents present. Only one interview was conducted with each family.

Discussion: While families often have quality experiences working with an OT and observe improvements in their children, some families do not receive quality services. This is due to lack of communication …

Access To Recreational Open Space In Patterson, Ca: A Geospatial Analysis Utilizing Geographic Information Systems, Leanne S. Lynch

Projects

Many cities throughout California have experienced land use shifts from prime agricultural land to developed industrial and residential areas without considering access to recreational open space. Access to recreation through open space or parks is beneficial for the health and well-being of the community while providing aesthetic value and potential preservation of local ecosystems. Since 2002 the City of Patterson, located in California’s Central Valley, has rezoned over 800 acres of agricultural land for urban and industrial use while developers reserved recreational open space (parkland) at locations inconvenient to existing neighborhoods. Although several acres of parkland have been added to …

Water Quality Evaluation Of Tire Derived Aggregate, Richela K. Maeda

Projects

The primary objective of this study is to investigate the rate that potential water quality contaminants leach from tire-derived aggregate (TDA) as a function of time. A laboratory and field experiment is conducted to provide insight into both controlled and field settings. The laboratory portion of this study also provides a basis for evaluating the effect that alternating periods of wet and dry weather have on the potential water quality impacts of the leachate as compared to the worst-case operating condition, when TDA is constantly submerged (i.e., when placed below the permanent groundwater table). The field experiment is used to …

Instructional School Gardens: Opportunities For And Barriers To Scaling, Patricia Sprague

Electronic Theses and Dissertations

When children are engaged in school gardens, they aren’t just digging in the dirt. School gardens have been shown to help improve student health by impacting food preferences and physical activity; to enhance learning in many subject areas; to encourage critical thinking skills by utilizing inquiry-based learning; and to engender a positive association with nature. Children from disadvantaged environments disproportionately may miss out on each of these important experiences. School gardens can serve as venues to enhance social justice by helping marginalized students access these advantageous experiences they otherwise might not have. Given the evidence that school gardens improve the …

Narratives Of Biculturalism: Arab-American Identity Negotiation Post-9/11, Janan Shouhayib

Psychology Honors Papers

The process of identity negotiation for bicultural individuals is ongoing and psychologically challenging. Arab-Americans in particular must deal with this process in a contentious environment where the Arab World is demonized and “Othered,” especially after 9/11. This project was an exploration of the identity development of Arab-American youth in a post-9/11 context. Background research for this study included a review of identity theory from Erik Erikson to postmodern thinkers, as well as the immigration patterns and historical-political context of Arab-Americans. Participants included 14 Arab-Americans from seven Arabic-speaking countries, five of whom were men and nine of whom were women, from …

Conceptualizing Cognitive-Behavioral Therapy As A Supportive-Educative Nursing System For Patients With Insomnia, Christine Kurtz, Nola Schmidt

Nursing and Health Professions Faculty Publications

Difficulty initiating and maintaining sleep is one of the most common health complaints of the general population. Approximately 35-50% of people experience occasional insomnia symptoms (Walsh et al., 2011) while 12-20% have insomnia disorder (Morin, et al., 2011; Roth et al., 2011). An effective treatment is cognitive behavioral therapy for insomnia (CBT-I; Schutte-Rodin, Broch, Buysse, Dorsey, & Sateia, 2008), a nonpharmacological, evidence-based intervention aimed at changing sleep behaviors. The purpose of this paper is to frame CBT-I as a nursing intervention for insomnia within the context of Orem’s self-care deficit nursing theory (Orem, 2001). Orem’s theory provides a framework from …

Within-Subjects Changes In Lipreading And Visual Enhancement Among Older Adults, Adam Harrison Voss

Independent Studies and Capstones

After 10-14 years, 14 older adults were retested to assess changes in Vonly ability and VE. Results showed no significant declines, however, strong correlations were found between previous V-only performance and current Vonly performance, as well as between previous VE and current VE, although not as strong. Age and PTA were not predictors of changes in lipreading or VE. In addition, older adults perform less well on auditory-only tasks over time.

Does Normalizing Gut Microbiota Decrease Exacerbation In Ibd, Franchesca Cook

Physician Assistant Scholarly Project Posters

Inflammatory bowel disease (IBD) including Crohn’s Disease (CD) and Ulcerative Colitis (UC) has become a more common diagnosis. The number of screenings for IBD has increased, drawing more attention to finding the cause. Researchers are finding that a change in diet, increased stress levels, and overuse of antibiotics may contribute to IBD by changing the gut microbiota (Skrautvol et al., 2011; Bernstein, 2010). Prebiotics and probiotics, an individualized anti-inflammatory diet, and lifestyle modification to decrease stress are all currently undergoing evaluation to discover a possible role in the reversal of IBD insult to the normal flora of the gut. This …

Nrf2 Pathway And The Reduction Of Oxidative Stress, Stephanie Jacobs Uselman

Physician Assistant Scholarly Project Posters

Oxidative stress has been linked to cellular damage initiating disease processes such as cardiovascular disease, diabetes, and cancer. The Nuclear factor erythroid-derived 2(Nrf2) pathway (Figure 1) aids in age-related cellular decline. The purpose of this study was to define the relationship between Protandim, its activation of the Nrf2 pathway, and decline in oxidative stress and cellular damage. The literature review included journal articles obtained from PubMed, Google scholar, and Cochrane review within the past 5-10 years, and contained both animal and human studies. The methods used in the animal studies included ANOVA, the standardized t-test, and the Neuman-Keuls post-test. P<0.05 was considered statistically significant. The human study included healthy participants, both male and female, age 29-78 with or without a specific medical diagnosis. Statistical analysis was based on the standardized t-test with a value of p<0.05 considered statistically significant. Liu et al. (2009) conducted a study investigating Protandim’s ability to suppress cancer tumor formation. Tumor incidence declined by 33% and multiplicity of skin tumors by 57% with p = 0.003. Superoxide dismutase increased 35%, catalase 58%, and manganese superoxide dismutase 21%. In 2013, Reuland et al. conducted a study to determine if Protandim could activate the Nrf2 pathway and induce antioxidant enzymes, thereby protecting cardiomyocytes from apoptosis. Results indicated that treated cardiomyocytes showed increased levels of Nrf2 nuclear accumulation, activation of endogenous antioxidant enzymes, and protection against cell targeted oxidative stress (p<0.05). Quereshi et al. (2010) completed a study to delineate if Protandim decreased oxidative stress through the Nrf2 pathway. After six months of supplementation, TBARS decreased by 48% (p=.006), and plasma osteopontin decreased by 57% (p=.018). In 2005, Nelson et al. conducted a study to determine if Protandim decreased cellular damage. After 30 days of supplementation, TBARS declined by 40% (p =0.0001), at 120 days, TBARS declined by 40-54% (p =0.002), and superoxide dismutase and catalase increased by 30% and 54% respectively. The results from studies indicate that Protandim’s activation of the Nrf2 pathway increased endogenous antioxidant availability, resulting in decreased oxidative stress and age related cellular damage.

A Multimodal Approach To Preventing And Treating Alzheimer’S Disease, Jason B. Smith

Physician Assistant Scholarly Project Posters

As of 2015 over 47 million people worldwide are diagnosed with Alzheimer’s disease (AD). The incidence of AD increases with age, and affects males and females equally. Current pharmacologic treatment includes two classes of drugs. The purpose of this study was to determine if a multimodal approach (i.e. diet, exercise, cognitive stimulation) towards the prevention and treatment of AD would be more beneficial than pharmacologic therapy alone. Research methods included reviewing peer reviewed journal articles published within the past five years obtained from PubMed, Dynamed, Cochrane, CINAHL, and Clinical Key. Ehret and Chamberlin (2015) found donepezil (Aricept) increased MMSE scores …
