Polyaniline/Cellulose Acetate Composite And Its Ammonium Ion Sensing Applications, Lei Li

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Conducting polymers have been investigated for years, since their discovery in 1977. Among them, polyaniline exhibits high electrical conductivity, leading to versatile applications, such as sensors, actuators, and catalysts. In this thesis, emeraldine salt polyaniline (ES-PANI) and cellulose acetate (CA) have been employed to produce composite fiber and films by three different methods: electrospinning, drop coating, and spin coating. The morphology and size of produced composites were studied by SEM. The results showed that the diameter of electrospun composite fiber decreases to nanosize, generating a nanofiber matrix that immobilize polyaniline particles. Sensing experiments were carried out at room temperature. Three …

Bio-Inspired Photon Absorption And Energy Transfer For Next Generation Photovoltaic Devices, Komal Magsi

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Nature's solar energy harvesting system, photosynthesis, serves as a model for photon absorption, spectra broadening, and energy transfer. Photosynthesis harvests light far differently than photovoltaic cells. These differences offer both engineering opportunity and scientific challenges since not all of the natural photon absorption mechanisms have been understood. In return, solar cells can be a very sensitive probe for the absorption characteristics of molecules capable of transferring charge to a conductive interface. The objective of this scientific work is the advancement of next generation photovoltaics through the development and application of natural photo-energy transfer processes. Two scientific methods were used in …

High Throughput Electrospinning Of High-Quality Nanofibers Via An Aluminum Disk Spinneret, Guokuo Zheng

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In this work, a simple and efficient needleless high throughput electrospinning process using an aluminum disk spinneret with 24 holes is described. Electrospun mats produced by this setup consisted of fine fibers (nano-sized) of the highest quality while the productivity (yield) was many times that obtained from conventional single-needle electrospinning. The goal was to produce scaled-up amounts of the same or better quality nanofibers under variable concentration, voltage, and the working distance than those produced with the single needle lab setting. The fiber mats produced were either polymer or ceramic (such as molybdenum trioxide nanofibers). Through experimentation the optimum process …

Squamous Cell Carcinoma Antigen 1 (Scca1) Promotes Mammary Tumorigenesis By Inducing The Unfolded Protein Response (Upr) And Il-6 Signaling, Namratha Sheshadri

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

SCCA1 is a member of the serine/cysteine protease inhibitor (serpin) family whose intracellular targets include lysosomal cathepsins L, S and K. Its expression correlates with resistance to cell death resulting from lysosomal membrane permeabilization and cathepsin release in response to radiation and chemotherapy. Elevated SCCA1 expression has been reported in a wide array of cancers including squamous cell carcinomas of the lung, head and neck, skin, cervix, as well as hepatocellular carcinoma. Our laboratory recently found that increased expression of SCCA1 also correlates with high-grade, poorly differentiated breast carcinoma and poor prognosis. However, despite SCCA1's clear relevance in human cancer, …

Microglia In The Healthy And Diseased Central Nervous System, Luisa Torres

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Spinal cord injury (SCI) results in the death of neurons, disruption of neuronal connections, demyelination, and inflammation. There are three phases of SCI: Acute (from the time of impact to the first few days post-injury), secondary (hours to weeks), and chronic (months to years). Currently, little can be done to modify the acute phase. Efforts to intervene have focused on the subsequent phases to both promote healing and prevent further damage. In this study I show that the small molecule inhibitor Pifithrin-μ (PFT-μ significantly reduced lesion volume and decreased the presence of inflammatory cells (microglia and macrophages) in the lesion …

The Role Of Phosphoinositide 3-Kinase In Regulating Kisspeptin Neurons Within The Hypothalamic-Pituitary-Gonadal Axis, Matthew John Alan Beymer

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Kisspeptin neurons are potent regulators of gonadotropin-releasing hormone (GnRH) neurons, necessary for pubertal development and adult reproductive competence. Estradiol (E₂) and testosterone (T), along with peripheral metabolic signals, such as leptin and insulin, regulate GnRH release indirectly, in part through the activation or inhibition of kisspeptin neurons. The changes in GnRH release and consequently in gonadotropin levels caused by these peripheral signals are strongly linked to changes in hypothalamic kisspeptin (Kiss1) gene expression. However, little is known about the intracellular signaling pathways that regulate Kiss1. The phospholipid enzyme phosphoinositide 3-kinase (PI3K) is a major downstream effector of steroid …

Unmasking The Nation: Disputing Of National Myths In The Work Of Cristina García | Unmasking The Nation: Disputing Of National Myths In The Work Of Cristina Garcã­A, Jaimee Lyn Christinat

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This thesis examines the ways in which Dreaming in Cuban, Monkey Hunting and A Handbook to Luck, three novels by Cristina Garcia, contradict and deconstruct popular national myths. In each novel, characters move between nations at key moments in each nation's history. Tracking these individuals' movements within a larger geopolitical framework allows for a new understanding of subaltern migration patterns. In each chapter, a specific aspect of movement is studied illustrating ways in which subaltern people are motivated and/or coerced to move from one nation or another, how their story becomes coopted by the larger national myth and where their …

De Pã­Caros Y Mentirosos En La Novela Picaresca Del Siglo De Oro | De Pícaros Y Mentirosos En La Novela Picaresca Del Siglo De Oro, Rafael Antonio Dueñas

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This dissertation examines how lying is an intrinsic characteristic within the genre of the picaresque novel through an exhaustive examination of canonical texts Lazarillo de Tormes, Guzmán de Alfarache and El Buscón. This dissertation first defines Saint Augustine's definition of lying in the fourth century then follows variations of the definition disseminated in the courts of the Spanish kings in the sixteenth and seventeenth centuries. The history of lying serves as a backdrop for understanding how lying is used in picaresque novels. It was in the fourth century that Saint Augustine laid down the foundation for how writers during the …

An Unholy Rebellion: Political Ideology And Insurrection In The Mayan Popul Vuh And The Andean Huarochiri Manuscript, Sharonah Fredrick

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Abstract of the Dissertation An Unholy Rebellion: Political Ideology and Insurrection in the Mayan Popul Vuh and the Andean Huarochiri Manuscript By Sharonah Esther Fredrick Doctor of Philosophy In Hispanic Languages and Literature Stony Brook University 2014 When the great Peruvian writer Jose Maria Arguedas observed that the Huarochiri Manuscript was a sort of Popul Vuh of Peruvian antiquity, he may or may not have perceived, (he does not elaborate) that the similarity was based on an extraordinary cynicism that pervaded both of these Native American manuscripts in the context of Spanish colonial America. The cynicism was directed at the …

Millennium Accidents, Breaking Narratives In Pedro Almodã³Var And Alejandro Gonzã¡Lez Iã±Ã¡Rritu | Millennium Accidents, Breaking Narratives In Pedro Almodóvar And Alejandro González Iñárritu, Anna S Shilova

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Millennium Accidents is an attempt to show the relation between the shattered, fragmented and decentralizing nature of contemporary, globalized reality and the texts it produces. In my research I aim to reveal the changes in the building and development of a story as a narrative and cognitive phenomenon. Economic globalization and the high-tech revolution have led to a modification of our mental, emotional and social functioning, converting the whole world into a huge network. Consequently, narrative-- be it verbal or iconic--shows the same metamorphosis as it generates multiple plots, neglects temporal and spatial conventions, and moves beyond national identities. Six …

Investigation Into The Impacts Of Foreign Ruling Elites In Traditional State Societies: The Case Of The Kassite State In Babylonia (Iraq), Helen Malko

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This thesis focuses on the study of foreign ruling minorities in traditional state societies. It investigates how the Kassites, as a foreign ethnic group, were able to control and maintain political power over the Babylonian majority for four centuries. It examines Kassite-Babylonian cultural interaction both on state and domestic levels as reflected in the material cultural and historical records. This study uses two contrasting ethnohistorical models of foreign ruling elites of the Arabs in Spain and the Mamluks in Egypt to evaluate the mechanisms employed by the Kassites to maintain power and the nature of their interaction with the Babylonian …

Piratical Designations: Power And Possibility In Representations Of Piracy, Michael D. High

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This dissertation analyzes how designations and representations of piracy define, police, and challenge legitimate production and circulation. From antiquity through the present, the labeling of others as pirates has excluded the less powerful from the authorized distribution of tangible and intangible property. Such discursive exclusion not only defines piracy but also creates it, distinguishing it from other, sanctioned forms of appropriation. This exclusion generates political, legal, and cultural subjectivity, thereby allowing so-called pirates to affect the very discourses and processes from which they are excluded. The first chapter traces the term piracy from its linguistic origin in Ancient Greece to …

A Study Modeling Secure Base Parenting Cognitions, Sandra Skinner

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Secure attachment is associated with a host of positive outcomes including higher levels of prosocial behavior and self-efficacy, better stress regulation, and a lower incidence of psychopathology. Secure base support and sensitive caregiving interactions are predictive of secure attachment. Interventions designed to promote sensitive caregiving have had success in both improving parental behaviors and in increasing levels of attachment security. These interventions are, however, too time consuming and resource intensive to be rolled out to the general population. This study sought to determine if a brief and easy to deliver intervention could be successful in enhancing secure base cognitions in …

Lighting Young Lights: The Junior Youth Spiritual Empowerment Program In Samoa, Nicholas Muccio

Independent Study Project (ISP) Collection

The Junior Youth Spiritual Empowerment Program (JYSEP) is a program inspired by the Baha’i Faith offered all around the world to those between the ages of 12 and 15. Due to its widespread implementation, it is likely that the practice of the program is in accordance with the cultural norms of the society in which it is practiced. The present study examines influences that the JYSEP has had on Samoan culture, and the influences that Samoan culture has had on the JYSEP. It has been found that the major values of the program are not in agreement with the traditional …

Exploring The Preservation Of Pastoralism And The Natural World In Western Mongolia , Josephine Brownell

Independent Study Project (ISP) Collection

At a time when Mongolia is experiencing the intense effects of land degradation, human activity, and climate change, it is crucial that a new land management framework is developed with conservation in mind. Pastoralism’s unique relationship with the land serves as a method of protecting the natural world for the future. This study focuses on a pastoral community in Western Mongolia while considering a main research question: Is a herder’s historically deep connection with the land enough to protect the modern pastoral lifestyle in Mongolia for years to come? In answering this question, a review of related previous studies on …

An Examination Of Governmental And Nongovernmental Organizations In Nepal: A Partnership In Managing And Eliminating Waste In The Solukhumbu, Kristen Kelliher

Independent Study Project (ISP) Collection

This study, examined whether governmental organizations and nongovernmental organizations in Nepal can effectively work together on eliminating trash and establishing waste management systems in the Solukhumbu region. Historically, the overwhelming presence of discarded items has detracted from tourists’ enjoyment of the Himalayas as well as caused severe environmental ramifications. In the last twenty years however, NGOs and GOs have begun to work together to address these issues and this project looks at whether their working relationship is effective as they often have different objectives and methodology for reaching those goals. Conducting ten personal interviews, visiting GOs and NGOs in Sagarmatha …

Matière Grise De Kivu Ruhorahoza : Un Nouveau Discours Filmique Pour Le Rwanda?, Charles J. Sugnet

Présence Francophone: Revue internationale de langue et de littérature

Films like Hotel Rwanda, Sometimes in April, and Shooting Dogs have codified certain ways of representing the 1994 Rwandan genocide, with realist aesthetics, epic sweep, and aspirations to historical authenticity. A young Rwandan director, Kivu Ruhorahoza, has won two major prizes at the Tribeca Festival for his 2011 feature Grey Matter, a breakthrough film that is different from its predecessors in almost every respect. Ruhorahoza’s film is intimate, cosmopolitan, metaphorical, and avant-garde; it requires some effort to understand, yet it is extremely moving. On the 20th Anniversary of the genocide in Rwanda, it offers new ways of understanding the consequences …

The Essentialism Of Music In Human Life And Its Roots In Nature, Katricia D. F. Stewart

Senior Theses

The connections between our emotions, music, and the natural world have only been examined in dualities, rather than as an interwoven triangle of elements that are innate and stem from our evolutionary history as a species. Our emotions are profoundly tied to musical sounds, while we also have a deeply rooted emotional connection with nature. The music of the natural world provided the foundation for crucial aspects of our human evolution, making our connections with both music and nature innate. Composers, musicians, poets, and storytellers have recognized this for centuries, exploiting these inherent connections in order to convey emotion and …
