Providing Clean Energy Solutions To India’S Bottom Of The Pyramid Population, Jill Howard, Fiona Wilson, E. Hachemi Aliouche

The Carsey School of Public Policy at the Scholars' Repository

Despite a scheme launched by the Indian government in 2017 that has declared achieving close to 100 percent electrification in the country, studies have shown that only 65 percent of rural enterprises in India report having electricity grid connection. While millions of households have been positively impacted by access to electricity, small businesses and smallholder farmers (those with holdings of less than 2 acres) in rural India have been left out of the equation or receive very unreliable power supply. Byproducts of the energy poverty experienced by India’s Bottom of the Pyramid population include an enormous carbon footprint produced by …

Introduction To Neutrosophic Genetics, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Neutrosophic Genetics is the study of genetics using neutrosophic logic, set, probability, statistics, measure and other neutrosophic tools and procedures. In this paper, based on the Neutrosophic Theory of Evolution (that includes degrees of Evolution, Neutrality (or Indeterminacy), and Involution) – as extension of Darwin’s Theory of Evolution, we show the applicability of neutrosophy in genetics, and we present within the frame of neutrosophic genetics the following concepts: neutrosophic mutation, neutrosophic speciation, and neutrosophic coevolution.

Ebola Virus Disease: The Biology, Pathology, Treatments, And Advancements, Dhruvi Patel, Eric Delgado, Peter Nasr

Kean Quest

Ebola virus disease (EVD) is caused by a virulent pathogen, which is a member of the viral family Filoviridae. It is a filamentous viral particle containing a single stranded, negative RNA. It causes extreme fatal hemorrhagic fever in both humans and non-humans. It is mainly found in Africa. Transmission of EVD occurs primarily through contact with infected body fluids. It causes immune suppression that eventually leads to multiple organ failure due to the proliferation. The World Health Organization (WHO) classified the 2013-2016 outbreak and after the current Ebola outbreak on August 1, 2018 in Dominican Republic of Congo (DRC), the …

The Best Predictions In Experimental Biology Are Critical And Persuasive, Douglas S. Fudge, Andy J. Turko

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A powerful way to evaluate scientific explanations (hypotheses) is to test the predictions that they make. In this way, predictions serve as an important bridge between abstract hypotheses and concrete experiments. Experimental biologists, however, generally receive little guidance on how to generate quality predictions. Here, we identify two important components of good predictions – criticality and persuasiveness – which relate to the ability of a prediction (and the experiment it implies) to disprove a hypothesis or to convince a skeptic that the hypothesis has merit. Using a detailed example, we demonstrate how striving for predictions that are both critical and …

A. catenella cells were most abundant in June, reaching 6,195 cells per …

Clusters Of Individuals Experiences Form A Continuum Of Persistent Non-Symbolic Experiences In Adults, Jeffery A. Martin

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

Persistent forms of nondual awareness, enlightenment, mystical experience, and so forth (Persistent Non-Symbolic Experience) have been reported since antiquity. Though sporadic research has been performed on these experiences, the scientific literature has yet to report a large-scale cognitive psychology study of this population. Method: Assessment of the subjective experience of 319 adult participants reporting persistent non-symbolic experience was undertaken using 6-12 hour semi-structured interviews and evaluated using grounded theory and thematic analysis. Results: Five core, consistent categories of change were uncovered: sense-of-self, cognition, affect, perception, and memory. Participants’ reports formed phenomenological groups in which the types of change …

International Journal of Speleology

Lying at the southernmost point of the Lucayan Archipelago, the Turks and Caicos Islands are amongst the better studied localities for anchialine cave biodiversity. For nearly five decades, novel invertebrate fauna, comprised primarily of crustaceans, have been collected from these tidally influenced pools – but new findings are always on the horizon. Herein we present new records of crustaceans and annelids from anchialine blue holes and horizontal caves of the Turks and Caicos. These findings include two potentially new species of meiofaunal annelids and a new species of remipede collected from a shallow water cave pool. Our 2019 expedition additionally …

When Water Isn't Wet: The Evolution Of Water Right Mitigation In Washington State, Rachael Osborn, Michael Mayer

Seattle Journal of Technology, Environmental & Innovation Law

What is water right mitigation?

The allocation of surface and ground water resources for out of stream uses via the western water rights doctrine of prior appropriation comes with serious environmental consequences – depletion of streamflow and aquifers. Over-appropriation by water rights has led to deleterious impacts on natural resources, including salmon survival, water quality, and public uses of state waterways.

Because of the over-appropriated condition of Washington’s rivers and aquifers, the issuance of new water rights has until recently required water-for-water or in-kind mitigation, with the goal to directly compensate for deleterious impacts. Historically, the Water Resources Program of …

Alternative Polyadenylation Modulates Expression Of Pro-Fibrotic Proteins And Contributes To Lung Fibrosis, Junsuk Ko

Dissertations & Theses (Open Access)

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease which affects about 5 to 8 million individuals in the world. Despite the high prevalence, there is currently no cure for IPF, and the cause of this disease is still unclear. Our laboratory and collaborators have shown that nudix hydrolase 21 (NUDT21, which is also known as cleavage factor 25, CFIm25) is a key regulator of alternative polyadenylation (APA). NUDT21 depletion causes 3’UTR shortening via APA leading to enhanced mRNA stability and protein translation. This NUDT21 reduction promotes tumor growth in glioblastoma by enhancing expression of oncogenes. Cancer and IPF share …

269— Age Of Colon Cancer Screening - A Retrospective Review, Christopher Cook

GREAT Day Posters

Colon cancer is the third most common cause of cancer-related death in the U.S. In 2019, the American Cancer Society predicted that 101,420 people in the U.S. would receive a new diagnosis of colon cancer. Due to this high prevalence, there has been a recent debate about the appropriate age to start colon cancer screening. Currently, the American Society of Gastroenterology recommends that screening start for average risk individuals at the age of 50. Conversely, the American Cancer Society has recently recommended that colon cancer screening for average risk individuals begin at the age of 45. The aim of our …

Substrate-Borne Vibrational Communication In Veiled Chameleons (Chamaeleo Calyptratus) During Courtship, Breeding, And Territoriality, Lauren Kappel

Masters Theses & Specialist Projects

Substrate-borne vibrations, or biotremors, are utilized by vertebrates found in unique environments because biotremors are an effective way to transmit signals through dense media. Previous studies have shown that veiled chameleons (Chamaeleo calyptratus) are able to produce biotremors via specialized neck muscles. I hypothesized that during courtship and/or breeding, the veiled chameleon, a tree-dwelling species, would communicate with biotremors through branches. Additionally, I hypothesized that female call characteristics would differ between reproductive condition (i.e., receptive and non-receptive), while male call characteristics would differ between behavioral contexts (i.e., territorial vs. courtship). Chameleons were paired (one male, one female) and placed on …

Individual Behavior Drives Ecosystem Function And The Impacts Of Harvest, Jacob E. Allgeier, Timothy J. Cline, Timothy E. Walsworth, Gus Wathen, Craig A. Layman, Daniel E. Schindler

Watershed Sciences Faculty Publications

Current approaches for biodiversity conservation and management focus on sustaining high levels of diversity among species to maintain ecosystem function. We show that the diversity among individuals within a single population drives function at the ecosystem scale. Specifically, nutrient supply from individual fish differs from the population average >80% of the time, and accounting for this individual variation nearly doubles estimates of nutrients supplied to the ecosystem. We test how management (i.e., selective harvest regimes) can alter ecosystem function and find that strategies targeting more active individuals reduce nutrient supply to the ecosystem up to 69%, a greater effect than …

Analyses Of The 2019 Nobel Prize In Physiology Or Medicine: Molecular Machinery For Cellular Oxygen Level Response, Neyda V. Gilman

Library Scholarship

Gregg L. Semenza, William G Kaelin, Jr, and Sir Peter J. Ratcliffe were awarded the 2019 Nobel Prize for Physiology or Medicine on October 7, 2019. Their work led to the understanding of how cells recognize and adapt to varying oxygen levels. Hypoxia-inducible nuclear factors play an essential role in this mechanism by turning on other genes that work towards increasing oxygen levels in hypoxic environments. Other vital pieces of the machinery include von Hippel-Lindau proteins and prolyl hydroxylation. Due to the necessity of oxygen in numerous human physiological systems, this discovery will likely have nearly immeasurable impacts on human …

Hydrods: Data Services In Support Of Physically Based, Distributed Hydrological Models, Tseganeh Zekiewos Gichamo, Nazmus S. Sazib, David G. Tarboton, Pabitra Dash

Publications

Physically based distributed hydrologic models require geospatial and time-series data that take considerable time and effort in processing them into model inputs. Tools that automate and speed up input processing facilitate the application of these models. In this study, we developed a set of web-based data services called HydroDS to provide hydrologic data processing ‘software as a service.’ HydroDS provides functions for processing watershed, terrain, canopy, climate, and soil data. The services are accessed through a Python client library that facilitates developing simple but effective data processing workflows with Python.

Association Between Breastfeeding And Child Stunting In Mexico, Ana Paola Campos, Mireya Vilar-Compte, Summer Sherburne Hawkins

Department of Public Health Scholarship and Creative Works

Background: Globally, the prevalence of child stunting has been decreasing over the past decades. How-ever, in low-and middle-income countries such as Mexico, stunting is still the most prevalent form of undernutrition affecting a large number of children in the most vulnerable conditions. Breastfeeding has been identified as one of the key affordable and modifiable maternal health behaviors protecting against child stunting. Objective: To examine the association between breastfeeding (defined as never breastfed, any breast-feeding for <6 months, and any breastfeeding for ≥6 months) and other individual-, household-, and area-level factors with child stunting (defined as length/height-for-age-z-score for sex under –2 standard deviations of the World Health Organization child growth standards’ median) in Mexico. Methods: Secondary data analysis using the 2012 Mexican Health and Nutrition Survey, which allowed representativeness of rural and urban areas at national level and among 4 regions in Mexico. Our subset included data on 2,089 singleton Mexican children aged 6–35 months with information on previously identified risk and protective factors for stunting. We conducted fixed-and mixed-effects logistic regression models sequentially controlling for each level of factors. Findings: Overall, 12.3% of children were stunted and 71.1% were breastfed for ≥6 months. Any breast-feeding and being female were consistent protective factors against child stunting across all models. In contrast, child low birthweight, maternal short stature, higher number of children aged <5 years per household, and moderate to severe food insecurity were consistent risk factors for child stunting across all models. Conclusions: According to our findings, efforts to reduce child stunting in Mexico should include prenatal strategies aiming to prevent low birthweight offspring particularly among short-stature women, moderate to severe food insecure households, families with a higher number of children aged <5 years, and indigenous communities. Postnatal components should include multilevel strategies to support breastfeeding.

Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout

Electronic Theses and Dissertations

Land use activities have caused disturbances that affect the quality of freshwater ecosystems worldwide. How the influences of land use along an environmental gradient and the associated environmental variables that may influence stream diversity and function is unclear. We address these issues by studying biodiversity, abundance, and functional diversity of macroinvertebrates across different land types along a gradient in Colorado, USA. We also address how diversity may change along an elevation gradient by analyzing previously published macroinvertebrate research. We found evidence that land use and disturbance are stronger explanations of changes in macroinvertebrate communities, rather than elevation. Functional trait patterns …

Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett

Graduate Student Theses, Dissertations, & Professional Papers

The brain is organized as a complex network of specialized neurons that communicate via a combination of electrical and chemical signals. Our brains function to generate movement, control organ function, or direct complex behaviors; all of which requires the ability to regulate the flow of communication between circuits and networks. Work in this thesis addresses two areas of neuron communication: first, how does the release of more than one neurotransmitter from a single neuron impact behavior, and second, are matricellular proteins (MCPs) key contributors to synaptic transmission and neuron function? The conserved CCN family of MCPs have a …

Application Of Optical Trapping To Obtain Single-Source Str Profiles From Forensically Relevant Body Fluid Mixtures With Modified Dna Analysis Workflow, Benjamin J. O'Brien

Master of Science in Forensic Science Directed Research Projects

Current methods of mixture separation in forensic DNA laboratories typically deconvolute the mixture after analysis using statistical analysis or probabilistic genotyping. To save time and effort of labs already backlogged, a method to separate mixtures on a cellular level before analysis needs to be developed. Optical trapping is a method that uses a focused 1064 nm laser to manipulate cells. Previous research has shown that approximately 50 spermatozoa or 15 leukocytes from a liquid sample are required to produce a full STR DNA profile. It was found that the number of spermatozoa required remains constant when the method of sample …
