Toward The Ultrasonic Sensing Of Organic Carbon In Seagrass-Bearing Sediments, Gabriel R. Venegas, Abdullah Rahman, Kevin M. Lee, Megan S. Ballard, Preston S. Wilson

School of Earth, Environmental, & Marine Sciences Faculty Publications

Ten percent of all organic carbon (Corg) absorbed by the ocean each year is stored in seagrass-bearing sediments. The preservation of these carbon stores is considered a vital method to mitigate climate change. Seagrass-bearing sediments have been correlated with sediment geophysical properties yet have not been related to sediment acoustic properties. For this purpose, sediment cores were collected from a Thalassia testudinum seagrass meadow in South Texas, USA, where geophysical, acoustical, and Corg properties were measured. It is hypothesized that when deposits of Corg adsorb onto mineral surfaces and are stored in pore spaces, compliant layers between grain contacts and …

How To Be Ssb-Free: Assessing The Attitudes And Readiness For A Sugar Sweetened Beverage-Free Healthcare Center In The Bronx, Ny, P. Christopher Palmedo, Lauren M. Gordon

Publications and Research

In recent years, communities and institutions have sought new interventions intended to reduce sugar sweetened beverage (SSB) consumption among children. Among these interventions are “SSB-free zones,” where such beverages are not permitted to be consumed on the premises. Insufficient knowledge still exists, however, about the readiness for such restrictive SSB policies within health care institutions. Understanding attitudes toward SSB consumption among adults is necessary to guide an institution-wide policy, where staff and patients serve as role models for parents and their children. We conducted focus groups with health center patients and staff to determine perceptions surrounding health and SSB consumption …

Cave Temperature And Management Implications In Lehman Caves, Great Basin National Park, Usa, Stanka Šebela, Gretchen Baker, Barbara Luke

Civil and Environmental Engineering and Construction Faculty Research

Cave air temperature was measured at six locations in Lehman Caves (USA) for one year at hourly intervals. Lehman is a show cave in a national park, treasured for its geological and biological resources. The two monitoring locations that are off of the tour route and, also, relatively distant from the cave’s entrances displayed nearly constant air temperature during the year. The other four sites, along the tour route, show daily temperature variation as well as annual fluctuation. After visitation levels decreased in the autumn, cave temperatures lagged but eventually reached an equilibrium which demonstrates recovery in the quiet winter. …

The Degenerating Star Clock: Circadian Clock Regulation Of Astrogliosis And Implications For Alzheimer’S Disease, Brian Vincent Lananna

Arts & Sciences Graduate Student Theses and Dissertations

Sleep disruption and circadian dysfunction are common symptoms of aging and neurodegenerative diseases, including Alzheimer’s disease (AD). The molecular rhythms in transcription/translation that govern these behavioral processes are mediated by clock genes and can be abrogated by deletion of the master circadian transcription factor Bmal1 (Arntl). We have shown that disruption of clock gene function in the mouse brain causes astrogliosis, synaptic damage, oxidative stress, and exacerbated neurodegeneration. However, the molecular mechanisms linking the circadian clock to these phenotypes and their implications for AD pathology remain largely unknown. Astrocyte activation occurs in response to diverse insults, and plays a critical …

Improved Orthopaedic Repairs Through Mechanically Optimized, Adhesive Biomaterials, Stephen Wheeler Linderman

McKelvey School of Engineering Graduate Student Theses & Dissertations

Despite countless surgical advances over the last several decades refining surgical approaches, repair techniques, and tools to treat tendon and tendon-to-bone injuries, we are still left with repair solutions that rely on fairly crude underlying mechanical principles. Musculoskeletal soft tissues have evolved to transfer high loads by optimizing stress distribution profiles across the tissue at each length scale. However, instead of mimicking these natural load transfer mechanisms, conventional suture approaches are limited by high load transfer across only a small number of anchor points within tissue. This leads to stress concentrations at anchor points that often cause repair failure as …

Subtypes Of Neglect In Relation To Reporting Practices, Safety Outcomes Among Known Cases, And Risk And Protective Factors, Chien-Jen Chiang

Arts & Sciences Graduate Student Theses and Dissertations

Objectives: The overall objective of this dissertation is to build knowledge about the phenomena of neglect subtypes to better guide prevention and child welfare intervention efforts in the future. The first aim focuses on how we come to officially identify cases of child neglect and its relationship to policies that set definitions for what is reportable in a given state. The second aim highlights whether or not there appear to be differences in safety and permanency outcomes for children known to CPS for different forms of neglect. The third aim focuses on why families may develop specific neglecting behaviors that …

A Formative Assessment Of The Vulnerability Context Of Three Indigenous Communities In Rural Ecuador For Improved Intervention Design, Ivy Blackmore

Arts & Sciences Graduate Student Theses and Dissertations

Nearly 20 % of the current world population are small-scale producers living in rural areas who rely on agriculture and related activities to support their families (IFAD, 2016; World Bank, 2008). Despite the almost 76 billion USD of official development assistance committed to agriculture improvement projects and associated activities over the past decade, many of the intended beneficiaries remain poor and struggle to meet their basic needs. The lack of success in addressing rural poverty highlights the need for quality research focused on understanding what type of intervention/s could help rural communities sustainably improve their livelihood security.The goal of this …

Ultrasound-Guided Optical Techniques For Cancer Diagnosis: System And Algorithm Development, Atahar Kamal Mostafa

McKelvey School of Engineering Graduate Student Theses & Dissertations

Worldwide, breast cancer is the most common cancer among women. In the United States alone, the American cancer society has estimated there will be 271,270 new breast cancer cases in 2019, and 42,260 lives will be lost to the disease. Ultrasound (US), mammography, and magnetic resonance imaging (MRI) are regularly used for breast cancer diagnosis and therapy monitoring. However, they sometimes fail to diagnose breast cancer effectively. These shortcomings have motivated researchers to explore new modalities. One of these modalities, diffuse optical tomography (DOT), utilizes near-infrared (NIR) light to reveal the optical properties of tissue. NIR-based DOT images the contrast …

Promoting Child Behavioral Health In Homeless Services: A Community-Based System Dynamics Approach, Katherine Marcal

Arts & Sciences Graduate Student Theses and Dissertations

Families with children comprise one-third of the entire homeless population (Henry, Watt, Rosenthal, & Shivji, 2017). Homelessness exposes children to chaotic, unsafe living environments that pose threats to healthy development; unsurprisingly, children in homeless services display high rates of mental health disorders compared to stably housed children (Bassuk et al., 2015; Buckner, 2008). Despite concerted efforts at the state and local levels to end family homelessness by 2020, rates have remained largely unchanged over the past decade (Henry et al., 2017; U.S. Interagency Council on Homelessness, 2015). Additional indicators such as increasing wait times, average length of stay, and reentry …

Health Care-Associated Infection Prevention Outcomes: Evaluating The Link Between Infection Prevention Practices In Healthcare Facilities And Their Health Care-Associated Infection Rates, Chidinma Veronica Njoku

UNLV Theses, Dissertations, Professional Papers, and Capstones

Healthcare-associated infections (HAI) are a pressing problem affecting vulnerable individuals who come to the hospital to receive care for one condition only to find that they have contracted another during their stay. Studies point to the importance of training and educating staff in order to implement and comply with recommended infection control and prevention control and prevention practices as lack of training and knowledge about infection control and prevention has been perceived to bring about a limited ability for direct care staff to adhere to recommended processes and activities. Although there are prior studies on the effects of assessments, infection …

A Combinatorial Approach Of Ionomics, Quantitative Trait Locus Mapping, And Transcriptome Analysis To Characterize Element Homeostasis In Maize, Alexandra Asaro

Arts & Sciences Graduate Student Theses and Dissertations

In plant systems, genetic and biochemical pathways impact uptake of elements from the soil. These environment-sensitive pathways often act in the root tissue to impact element concentrations throughout the plant. In order to characterize element regulation as well as apply ionomics to understand plant adaptation, perspectives are needed from multiple tissues and environments and from approaches that take interactions between elements into account. The work described in this thesis includes multi-environment and multi-tissue experiments that connect variation in genetic sequence, and in gene expression, with variation in element accumulation. The associations found here include those that are sensitive to environment, …

Development Of Enteric Neurons And Muscularis Macrophages, Marina Avetisyan

Arts & Sciences Graduate Student Theses and Dissertations

The enteric nervous system (ENS) is a complex interconnected network of neurons and glia in the bowel wall that regulates intestinal motility, blood flow, and epithelial function. The ENS also controls aspects of inflammatory signaling within the bowel. To perform these tasks, there are at least 20 types of enteric neuron and four types of enteric glia. Although much is known about early events in ENS development, signals governing the development of specific neuronal subtypes and communication with neighboring cell types within the bowel remain poorly understood. One fundamental hypothesis is that diverse trophic factors support distinct neuronal populations in …

Exploring The Complexities Of Real World Upper Limb Performance After Stroke, Kimberly Waddell

Arts & Sciences Graduate Student Theses and Dissertations

Stroke is the leading cause of long-term disability in the United States. Hemiparesis, or weakness on one side of the body, is a common impairment following a stroke. Approximately 80% of individuals with stroke will experience upper limb paresis, with only a small percentage regaining full functional use of their paretic upper limb. Individuals report ongoing difficulties with incorporating their paretic upper limb into routine activities after a stroke. Rehabilitation interventions often try to increase real world upper limb use by improving what an individual is capable of doing (i.e. capacity) in the rehabilitation clinic. Both clinicians and researchers assume …

Mechanics Of Phenotypic Aging Trajectories In C. Elegans And Humans, William Zhang

Arts & Sciences Graduate Student Theses and Dissertations

Overall, my dissertation integrates longitudinal measurements of physiology to investigate the aging process. In the first half, I examine the surprising and largely unexplained degree of variation in lifespan within even homogeneous populations. I sought to understand how physiological aging differs between long- and short-lived individuals within a population of genetically identical C. elegans reared in a homogeneous environment. Using a novel culture apparatus, I longitudinally monitored aspects of aging physiology across a large population of isolated individuals. Aggregating several measures into an overall estimate of senescence, I find that long- and short-lived individuals start adulthood on an equal physiological …

The Ontogeny Of Complex Tool Use Among Chimpanzees Of The Goualougo Triangle, Republic Of Congo, Stephanie L. Musgrave

Arts & Sciences Graduate Student Theses and Dissertations

Various factors are hypothesized to have contributed to the flourishing of technology during human evolution, including high-fidelity social learning, a propensity for prosocial helping, and sex differences in foraging tool use. In this research, we examined the role of these factors on the development of complex tool-using skills among wild chimpanzees (Pan troglodytes troglodytes) in the Goualougo Triangle, Republic of Congo. These apes exhibit among the most complex tool behaviors of any nonhuman animal, including the flexible use of multiple tool types and the manufacture of tools from specific raw materials, according to a particular design. Specifically, we drew upon …

The Role Of Ifrd1 In The Recruitment And Function Of Reserve Stem Cells In Regeneration And Cancer, Mark Anthony Lewis

Arts & Sciences Graduate Student Theses and Dissertations

Mature cells can reprogram into a proliferative, progenitor-like state to repair tissue following injury and inflammation. Differentiated cells in diverse tissues can become proliferative via a dedicated, evolutionarily conserved program we termed paligenosis. We detailed how paligenosis occurs, in both gastric chief and pancreatic acinar cells, in a step-wise manner that involves: 1) autodegradation of mature cell components; 2) re-expression of progenitor genes; 3) re-entry into the cell cycle. This process is governed by mTORC1, a fundamental cellular energy sensor and regulator of protein translation. Blocking mTORC1 permitted autophagy and metaplastic gene induction but blocked cell cycle re-entry at S-phase. …
