Effect Of Burning And Management Alternatives On Forage Litter Composition Of A Native Pasture, I. Heringer, A. V. A. Jacques

IGC Proceedings (1977-2023)

The content and quantities of nutrients in forage and litter was evaluated in native pasture under grazing, submitted to burning and alternatives practices. The experimental design was a completely randomized, with three replications. The biennial burning has no effect in nutrients contents of the forage, but in the case of litter plus senescent material the concentration of Ca and Mg decreased as compared to the systems without burning. The sod-seeding treatment increased the nutrient contents in the alive and dead tissues. Nutrient accumulation on forage tissue and litter plus senescent material, was highest in the systems without burning.

Synapsej: An Automated, Synapse Identification Macro For Imagej, Juan Felipe Moreno Manrique, Parker R. Voit, Kathryn E. Windsor, Aamuktha Reddy Karla, Sierra R. Rodriguez, Gerard M.J. Beaudoin Iii

Biology Faculty Research

While electron microscopy represents the gold standard for detection of synapses, a number of limitations prevent its broad applicability. A key method for detecting synapses is immunostaining for markers of pre- and post-synaptic proteins, which can infer a synapse based upon the apposition of the two markers. While immunostaining and imaging techniques have improved to allow for identification of synapses in tissue, analysis and identification of these appositions are not facile, and there has been a lack of tools to accurately identify these appositions. Here, we delineate a macro that uses open-source and freely available ImageJ or FIJI for analysis …

Pareto Optimality And Compromise For Environmental Water Management, Sarah E. Null, Marcelo A. Olivares, Felipe Cordera, Jay R. Lund

Watershed Sciences Faculty Publications

Water management usually considers economic and ecological objectives, and involves tradeoffs, conflicts, compromise, and cooperation among objectives. Pareto optimality often is championed in water management, but its relationships with the mathematical representation of objectives, and implications of tradeoffs for Pareto optimal decisions, are rarely examined. We evaluate the mathematical properties of optimized tradeoffs to identify promising regions for compromise, suggest strategies for reducing conflicts, and better understand whether decision-makers are more or less likely to cooperate on environmental water allocations. Cooperation and compromise among objectives can be easier when tradeoff curves are concave and more adversarial when tradeoff curves are …

Egg Plastron Of The Bog Copper Butterfly Tharsalea (Epidemia) Epixanthe (Bsd. & Le C. [1835]) (Lycaenidae: Lycaeninae), David M. Wright

The Taxonomic Report of the International Lepidoptera Survey

The egg of the Bog Copper butterfly, Tharsalea (Epidemia) epixanthe, has a prominent highly-sculptured chorionic surface. Trapped within the chorion is a labyrinth of air spaces which has been proposed as a plastron for gas exchange while the egg is submerged in water. Data derived from scanning electron microscopy (SEM) confirms the plastron should function as predicted. Furthermore, the insulating air spaces should prevent water loss of the diapausing first instar larvae while overwintering.

Molecular Analysis Of Mchm Toxicity In Zebrafish, Cassandra Pelton

Honors College Theses

In early 2014 Freedom Industries, located in Charleston, WV, leaked approximately 10,000 gallons of 4-methylcyclohexane methanol into the Elk River. This river serviced approximately 300,000 people as a source of municipal water. Its effects on the people and surrounding wildlife is largely unknown.

Chemicals in surface runoff have the potential to induce aquatic animal trait changes, such as altered movement and feeding, that can ultimately alter predator-prey dynamics in aquatic systems. However, chemicals with high potential to enter aquatic systems, like 4-methylcyclohexane methanol (MCHM) used to clean coal, were tested using only short-term, single-species studies prior to use. Data from …

What Does It Mean To Be Deaf? Changing Meanings Of Deafness, Communication Technology, And Beliefs About Normality In The Us, Kathryn Elizabeth Burrows

Dissertations and Theses

How deafness is perceived as a problem by society dictates what types of technologies are leveraged to address the problem, and, conversely, available technologies shape how deafness is perceived. In this dissertation, I draw on multiple methods to explore the meanings of deafness in the US since the early 18^th century to the present, examine how the meanings of deafness in those eras shaped deaf technology, and assess how available technologies shaped how deafness was understood. Using primary and secondary historical sources, I identify that every era identifies a different "problem of being deaf" and it is that problem …

Russian Disinformation – The Technological Force Multiplier, Elizabeth Kilkenny

Global Insight

Part one of this article is a Literature Review assessing the state of the collected works of arguments surrounding the comparison and contrasting of older Soviet and contemporary Russian disinformation campaigns. There were two main overarching ideas that kept reemerging: either there is no practical difference or technological change is the only real difference, and even then, some believe it is just a natural evolution of these systems of disinformation. Other less frequent ideas surrounding this analysis are also highlighted as potentially important variables. After reviewing these previous works, the second part of this piece delves deeper into the topic …

The Remains Of Castas In Latin America, Susana Escobar Zelaya

Global Insight

Casta paintings are a collection of works that were predominantly produced in colonial Mexico. These paintings are a representation of the different classifications of race between Spaniards, Blacks, and Indigenous people. The paintings emphasize clothing and setting as a way to distinguish social and economic standings in regard to race. Casta paintings are more than racial documentation; they are a guide to understanding how ideas and beliefs on race came to be in Latin America. This article explores the origins of casta paintings and their long-lasting impact in Latin America. Casta paintings are investigated in books, academic journals, essays, and …

Investigating Differences In Academic Intrinsic, Extrinsic, And Amotivation Among Children Of Immigrant Parents, Natasha Pooran

Global Insight

College students in the US often experience a pressure to succeed brought on by their unique intrinsic and extrinsic motivations. However, is there a possible connection between these academic motivations and having an immigrant parent? To determine if differences exist in intrinsic, extrinsic, and amotivation among children of immigrant parents (CIPs), I employed a 28-item survey adapted from the Academic Motivation Scale (AMS). I analyzed survey data collected from 183 undergraduate students at the University of Texas at Arlington using three chi-square tests of independence comparing the three types of motivation in CIPs and non-CIPs and a one-way analysis of …

BACKGROUND: The underlying pathogenesis of cerebral palsy (CP) remains poorly understood. The possibility of an early inflammatory response after acute insult is of increasing interest. Patterns of inflammatory and related biomarkers are emerging as potential early diagnostic markers for understanding the etiologic diversity of CP. Their presence has been investigated in plasma and umbilical cord blood but not in cerebrospinal fluid (CSF).

METHODS: A clinical CP sample was recruited using a single-time point cross-sectional design to collect CSF at point-of-care during a standard-of-care surgical procedure (intrathecal pump implant). Patient demographic and clinical characteristics were sourced from medical chart audit.

School of Medicine Publications

The prognostic implications of isolated diastolic hypertension (IDH), as defined by 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines, have not been tested using ambulatory blood pressure (BP) monitor thresholds (ie, 24-hour mean systolic BP ≥75 mm Hg). We analyzed data from 11 135 participants in the IDACO (International Database on Ambulatory Blood Pressure in Relation to Cardiovascular Outcomes). Using 24-hour mean ambulatory BP monitor values, we performed Cox regression testing independent associations of IDH with death or cardiovascular events. Analyses were conducted in the cohort overall, as well as after age stratification (≥50 years). The median age …

Epigenetic Dynamics Shaping Melanophore And Iridophore Cell Fate In Zebrafish, Hyo Sik Jang, Yujie Chen, Jiaxin Ge, Alicia N Wilkening, Yiran Hou, Hyung Joo Lee, You Rim Choi, Rebecca F Lowdon, Xiaoyun Xing, Daofeng Li, Charles K Kaufman, Stephen L Johnson, Ting Wang

2020-Current year OA Pubs

BACKGROUND: Zebrafish pigment cell differentiation provides an attractive model for studying cell fate progression as a neural crest progenitor engenders diverse cell types, including two morphologically distinct pigment cells: black melanophores and reflective iridophores. Nontrivial classical genetic and transcriptomic approaches have revealed essential molecular mechanisms and gene regulatory circuits that drive neural crest-derived cell fate decisions. However, how the epigenetic landscape contributes to pigment cell differentiation, especially in the context of iridophore cell fate, is poorly understood.

RESULTS: We chart the global changes in the epigenetic landscape, including DNA methylation and chromatin accessibility, during neural crest differentiation into melanophores and …

INTRODUCTION: Less than 40% of patients with ovarian cancer (OC) in the USA receive stage-appropriate guideline-adherent surgery and chemotherapy. Black patients with cancer report greater depression, pain and fatigue than white patients. Lack of access to healthcare likely contributes to low treatment rates and racial differences in outcomes. The Ovarian Cancer Epidemiology, Healthcare Access and Disparities study aims to characterise healthcare access (HCA) across five specific dimensions-Availability, Affordability, Accessibility, Accommodation and Acceptability-among black, Hispanic and white patients with OC, evaluate the impact of HCA on quality of treatment, supportive care and survival, and explore biological mechanisms that may contribute to …

Questions To Measure Enjoyment Of And Satisfaction With Physical Activity: Are They Appropriate For Use In An Older Population?, Mary Katherine Huffman, Sharon L. Christ, Kenneth F. Ferraro, David B. Klenosky, Kristine Marceau, Steve Amireault

Purdue University Libraries Open Access Publishing Fund

Background and Objectives

Enjoyment of and satisfaction with physical activity have been proposed as two actionable mechanisms to promote sustained engagement in physical activity. An accurate understanding of how, why, and for whom these two mechanisms work (or not) in response to a particular intervention strategy is contingent on having suitable measures for the population of interest. This study aims to determine whether the Physical Activity Enjoyment Scale-8 and a novel approach to the measurement of satisfaction with physical activity are suitable for use among older adults (Mage = 66.25 years; range = 55–91 years).
