The Impact Of Gut Passage By Binturongs (Arctictus Binturong) On Seed Germination, Christina P. Colon, Ahimsa Campos-Arceiz

Publications and Research

Binturongs (Arctictis binturong) are the largest of Asian civets and, due to their highly frugivorous diet, are expected to play an important role in seed dispersal processes. To study the effect of binturong gut passage on seed viability, we fed 10 captive binturongs with fruits of longan (Dimocarpus longan), papaya (Carica papaya) and chiku (Manilkara zapota), collected the seeds they defaecated, and planted these to determine seed germination rate and time. Of the defaecated seeds, 90.4% passed through binturong gut intact in under nine hours, and 99.4% passed in under 33 hours. Chiku seeds had the highest germination rate (35.7% …

The Field Experiences Of Student Teachers And Effective Mathematics Teaching In Turkey, Guney Haciomeroglu

Australian Journal of Teacher Education

The aim of this study was to investigate the cooperative teachers’ supervision for effective mathematics teaching from the perspective of elementary student teachers during their field experiences. The participants were 259 senior elementary education majors (189 female and 70 male) who were enrolled in practicum courses at a Turkish university. Results of the study revealed that cooperative teachers as a supervisor seemed to be deficient for interacting with student teachers as well as assisting them to develop critical point of views for teaching mathematics effectively. The study suggests that faculty-school partnership should be reconsidered for selection and professional development of …

Key threats to water sustainability in the Middle Rio Grande River region include: (1) increasing salinization of surface and ground water, (2) increasing water demand from a growing population in the El Paso/Ciudad Juarez area on top of an already high base demand from irrigated agriculture, (3) …

Link Between Cancer And Alzheimer Disease Via Oxidative Stress Induced By Nitric Oxide-Dependent Mitochondrial Dna Overproliferation And Deletion, Gjumrakch Aliev, Mark E. Obrenovich, Shams Tabrez, Nasimudeen R. Jabir, Prakash Reddy, Yi Li, Geoffrey Burnstock, Ramon Cacabelos, Mohammad Amjad Kamal

Chemistry Faculty Research & Creative Works

Nitric oxide- (NO-) dependent oxidative stress results in mitochondrial ultrastructural alterations and DNA damage in cases of Alzheimer disease (AD). However, little is known about these pathways in human cancers, especially during the development as well as the progression of primary brain tumors and metastatic colorectal cancer. One of the key features of tumors is the deficiency in tissue energy that accompanies mitochondrial lesions and formation of the hypoxic smaller sized mitochondria with ultrastructural abnormalities. We speculate that mitochondrial involvement may play a significant role in the etiopathogenesis of cancer. Recent studies also demonstrate a potential link between AD and …

Particle Shape Enhances Specificity Of Antibody-Displaying Nanoparticles, Sutapa Barua, Jin-Wook Yoo, Poornima Kolhar, Aditya Wakankar, Yatin R. Gokarn, Samir Mitragotri

Chemical and Biochemical Engineering Faculty Research & Creative Works

Monoclonal antibodies are used in numerous therapeutic and diagnostic applications; however, their efficacy is contingent on specificity and avidity. Here, we show that presentation of antibodies on the surface of nonspherical particles enhances antibody specificity as well as avidity toward their targets. Using spherical, rod-, and disk-shaped polystyrene nano- and microparticles and trastuzumab as the targeting antibody, we studied specific and nonspecific uptake in three breast cancer cell lines: BT-474, SK-BR-3, and MDA-MB-231. Rods exhibited higher specific uptake and lower nonspecific uptake in all cells compared with spheres. This surprising interplay between particle shape and antibodies originates from the unique …

Dimethyl Sulfoxide (Dmso) Exacerbates Cisplatin-Induced Sensory Hair Cell Death In Zebrafish (Danio Rerio), Phillip M. Uribe, Melissa A. Mueller, Julia S. Gleichman, Matthew D. Kramer, Qi Wang, Martha Sibrian-Vazquez, Robert M. Strongin, Peter S. Steyger, Douglas A. Cotanche, Jonathan I. Matsui

Chemistry Faculty Publications and Presentations

Inner ear sensory hair cells die following exposure to aminoglycoside antibiotics or chemotherapeutics like cisplatin, leading to permanent auditory and/or balance deficits in humans. Zebrafish (Danio rerio) are used to study drug-induced sensory hair cell death since their hair cells are similar in structure and function to those found in humans. We developed a cisplatin dose-response curve using a transgenic line of zebrafish that expresses membrane-targeted green fluorescent protein under the control of the Brn3c promoter/enhancer. Recently, several small molecule screens have been conducted using zebrafish to identify potential pharmacological agents that could be used to protect sensory hair cells …

Sector Expansion And Elliptical Modeling Of Blue-Gray Ovoids For Basal Cell Carcinoma Discrimination In Dermoscopy Images, Pelin Guvenc, Robert W. Leander, Serkan Kefel, William V. Stoecker, Ryan K. Rader, Kristen A. Hinton, Sherea Monica Stricklin, Harold S. Rabinovitz, Margaret C. Oliviero, Randy Hays Moss

Chemistry Faculty Research & Creative Works

Background: Blue-gray ovoids (B-GOs), a critical dermoscopic structure for basal cell carcinoma (BCC), offer an opportunity for automatic detection of BCC. Due to variation in size and color, B-GOs can be easily mistaken for similar structures in benign lesions. Analysis of these structures could afford accurate characterization and automatic recognition of B-GOs, furthering the goal of automatic BCC detection. This study utilizes a novel segmentation method to discriminate B-GOs from their benign mimics.

Methods: Contact dermoscopy images of 68 confirmed BCCs with B-GOs were obtained. Another set of 131 contact dermoscopic images of benign lesions possessing B-GO mimics provided a …

Categorizing Women: Gender And Social Media During The 2011 Egyptian Revolution, Sydney Winston Barnes

Theses and Dissertations

From February 2011 to July 2012, formerly suppressed political parties struggled to fill the political void post-Hosni Mubarak. While debates about Egypt's political future circulated, individuals as well as dissident factions employed various interpretations of women and their roles to symbolically represent their varying ideologies. Despite the significance and economic value women produce as citizens, many political actors regularly bracket their concerns as irrelevant to the affairs of the state. As a result, political actors have engaged with new strategic techniques to access the various politicized publics that marginalized subaltern groups. The most publicized approach during this time, involved individual's …

A Study Of The Ionic Diffusion Under The Effect Of Electric Field (Computer Simulation With Reference To Biological Membrane), Hagar Mohamed Fawzy

Theses and Dissertations

The biophysical studies of the biological system are far from being conclusive. Not only because this science is relatively recent, but also because of the lack of physical data. Also there are a lot of contradicting views among researchers as well as the poor theoretical interpretation of the reported experimental data. However, the advent of computer science with the considerable storage capability and highly vast calculations gives modeling techniques a great advantage and opens a real door to better understanding of the complicated biological phenomena. The present thesis addressed the problem of ionic penetration through biological tissue under the effect …

The Potential Rise Of An Islamist Youth Within 25 January Revolts: A Case Study Of The Muslim Brotherhood Youth, Dina Hosni

Theses and Dissertations

The thesis endeavors to offer a fresh perspective on the potential rise of Islamist youth, focusing on the pro-change ex-current MB youth as a potential subculture within 25 January and the assumption of the Egyptian MB to power. To validate this hypothesis, Gramsci's theory on hegemony and counter-hegemony has been deployed to study the rise of pro-change MB youth against Mubarak's authoritarian regime on the state level in tandem with counter-hegemony against the strict al-samc w-al-ṭāca principle (i.e. blind obedience) on the organizational level. Elements of social movement theory have been used to substantiate the relevance of counter-hegemony, namely, Gamson's …

The Acquisition Of Morphosyntactic Agreement In The Interlanguage System Of Afl Learners In Ghana, Alhassan Abdur-Rahim Husein

Theses and Dissertations

Despite the relevance of agreement structures in constructing the interlanguage (IL) system of the L2 learner, not much research has been conducted in this area on Arabic language learners. This study investigated the acquisition of morphosyntactic agreement structures by Arabic as Foreign Language (AFL) learners in Ghana, using the Processability Theory (PT) formulated in Pienemann (1998, 2005). The theory predicts cross-linguistic developmental routes for the acquisition of grammatical structures. A cross-sectional study was performed in order to test the theory. Data were elicited from 15 participants from the University of Ghana, Legon using Grammaticality Judgment Task and Elicited Production Task. …

Design Flow Factors Using Socioeconomic Based Synthetic Wastewater Hydrographs For Small Communities, Haitham Yousri Elnakar

Theses and Dissertations

Reliable estimation of sewage flow rates is essential for the proper design of sewers, pumping stations, and treatment plants. The widely used design peaking factors for sewerage systems are usually related to the population served or the average sewage flow rate ignoring the difference between communities having same population but different socio-economic conditions and water use practice. In this study, a simulation model is developed to generate synthetic wastewater flow hydrographs resulting from a community with specific socio-economic conditions. The synthetic hydrographs are developed while retaining their commonly observed random behavior. The socioeconomic characteristics of a community are accounted for …

Water pollution by toxic heavy metals is one of the most serious environmental hazards to humans’ health. As they are emitted into the water resources and adsorbed by soil, plants, fish and animals and eventually accumulate in human bodies causing a variety of serious diseases. Therefore, there is an urgent need to develop a continuous, rapid, automatic, and on-site heavy metals environmental monitoring system for the online detection of heavy metals pollution at various water resources and industrial waste networks. In this thesis the main objective is to develop a microfluidic platform for heavy metal analyte sensing in which a …

Molecular Dynamics Simulation And Phase Transitions Of Tetrafluoromethane, Rasha Ibrahim Abdulshahid

Theses and Dissertations

Properties of material under extreme conditions, whether high pressures, high temperatures or low temperatures, are rather interesting. Understanding the properties of any given material at such extreme conditions provides a much clearer conception of the properties of this material in general. Although until recently studying the nature of matter under such extreme conditions was not possible via the traditional experimental or traditional methods, it was made possible by the utilization of computer simulation methods. Carbon tetrafluoride has been gaining wide interest in recent years due to its important role in the semiconductor processing industries. It is one of the most …

Increasing Blood Donation In Egypt, Azza Akram Shafei

Citizen science, participatory research, and volunteer monitoring all describe research where data are collected by non-professional collaborators. These approaches can allow for research to be conducted at spatial and temporal scales unfeasible for professionals, especially in current budget climates. Mobile computing apps for data collection, training, and analysis can greatly enhance participatory science.

New Best Management For Phosphorus In The Water, Gina Peek, Chad Penn, Jorge H. Atiles

Journal of Extension

Phosphorus (P) is a macronutrient required by all life forms. P occurs in the environment naturally and may be introduced during farming and household activities in the form of fertilizers. Extension can play a critical role in helping to reduce commercial and household impacts of excess P in soils. Agents can help clients using education and introducing them to best management practices, including a phosphorus removal structure. It is a passive filtration system that removes P from runoff and drainage ditches before it reaches sensitive water bodies.

Impacts Of Black Box Warning, National Coverage Determination, And Risk Evaluation And Mitigation Strategies On The Inpatient On-Label And Off-Label Use Of Erythropoiesis-Stimulating Agents, Arpamas Seetasith

Theses and Dissertations

Background: FDA black box warning, Risk Evaluation and Mitigation Strategies (REMS), and CMS national coverage determination (NCD) aim to reduce inappropriate use of erythropoiesis-stimulating agents (ESAs) that are widely used in anemic patients. Previous studies have not linked specific safety interventions to changes in ESA utilization patterns in the inpatient settings nor assessed such interventions on off-label use of the drugs. Ineffectiveness of the intervention and lag time between such interventions and the observed change in clinical practice could lead to serious clinical outcomes. In addition, such interventions may unintentionally reduce on-label and some off-label use of ESAs considered “appropriate” …

Comparison Of A Sio2-Cao-Zno-Sro Glass Polyalkenoate Cement To Commercial Dental Materials: Glass Structure And Physical Properties, A. W. Wren, A. Coughlan, F. R. Laffir, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

Glass polyalkenoate cements (GPCs) have previously been considered for orthopedic applications. A Zn-GPC (BT 101) was compared to commercial GPCs (Fuji IX and Ketac Molar) which have a setting chemistry analogous to BT 101. Handling properties (working, T_w and setting, T_s times) for BT 101 were shorter than the commercial GPCs. BT 101 also had a higher setting exotherm (S_x - 34 °C) than the commercial GPCs (29 °C). The maximum strengths for BT 101, Fuji IX, and Ketac Molar were 75, 238, and 216 MPa (compressive, σ_c), and 34, 54, and 62 MPa (biaxial …

Searching Mindfully: Are Libraries Up To The Challenge Of Competing With Google Books?, Amrita Dhawan

Library Philosophy and Practice (e-journal)

Traditional research tools used by libraries, such as encyclopedias and catalogs were created in an age of print and information scarcity. They have not kept up with changes in the information world, including an abundance of online information in different formats and the rise of interdisciplinary topics which attempt to solve ‘real world’ messy problems and not traditional theoretical questions. The traditional tools rest on collaboration between OCLC, LOC, private aggregators, librarians and faculty. The search results they deliver offer excessive information with very little guidance on how to systematically sift through them. This makes the research process harder and …

Reducing The Divorce Rate Among Christians In America: Making Premarital Counseling Prerequisite For Marriage, Scott Vail

Doctoral Dissertations and Projects

God instituted the covenant of marriage to provide the means by which two individuals become one for life. This covenant between a man and a woman is intended to satisfy the God-given longing each person has to love and be loved for a lifetime. The reality is, according to the U.S. Bureau of the Census, 2008, the divorce rate in America is nearly fifty percent. To remedy this, the church must require a formal premarital program as a prerequisite for marriage. The result would be fewer divorces and an increase in marital satisfaction. Resources formerly consumed by counseling and ministering …
