Phenotypic Evaluation Of Transgenic Peas (Pisum Sativum L.) Harboring Atnhx1 Demonstrates Stable Gene Expression And Conserved Morphology In Subsequent Generations, Zahid Ali, Wajeeha Saeed, Saadia Naseem, Faheem Ahmad, Ahmed Akrem, Nighat Yasmeen, Hans Joerg Jacobsen

Turkish Journal of Botany

In recent years, transgenic approaches have played a significant role in improving traits that help plants overcome abiotic stresses. Combined gene discovery and functional genomics have helped identify diversified mechanisms and gene families, which improved productivity under various abiotic stresses. We report on the genetic stability and persistent morphological features of transgenic pea (Pisum sativum L.) plants harboring the dicistronic vector construct pG0229MASnhx1/luc over five generations. In addition to salt stress tolerance, the transgenic plants showed frost tolerance compared to wild-type (WT) plants. Frost tolerance of AtNHX1 transgenic pea plants was unexpected and needs further investigation. We report morphological and …

Host-Driven Morphological Variability In Orobanche Crenata (Orobanchaceae), Gianniantonio Domina

Turkish Journal of Botany

Studies on interactions between Orobanche species and their hosts are mainly focused on resistance, radical interactions, and haustorium development. The influence of the host plant on morphology of the parasite under environmental controlled conditions is not reported in the literature. With the aim of filling this gap, the results of cultivation experiments of Orobanche crenata on Vicia faba, V. sativa, Pisum sativum, Cicer arietinum, and Lathyrus clymenum are presented. The tested population of O. crenata infected all the studied hosts but showed preferences toward Vicia and Pisum and, in particular, toward a foreign V. sativa cv. The higher resistance of …

Notes On The Genus Frondaria (Orchidaceae) With Description Of New Species, Dariusz Szlachetko, Marta Kolanowska, Max Rykaczewski

Turkish Journal of Botany

The specific diversity of Neotropical orchid genus Frondaria is evaluated based on morphological data. Frondaria was considered a monospecific taxon for years; however, our recent studies on Andean orchids indicated that it is actually much more variable. Within Colombian material, we found a species which does not fit the morphological description of F. caulescens and described it here as a new species named F. colombiana . The novelty is characterized by inflorescence being three times as long as the ramicaul, the tridentate leaf apex with middle tooth as long as lateral ones, papillate apices of sepals, and oblong-ligulate lip middle …

Players In A Storm: Climate And Political Migrants In The Tempest And Othello, Darcie Rees

Master's Theses and Doctoral Dissertations

This paper presents a reading of migrants and their relationships with political and environmental slow violence in William Shakespeare’s The Tempest and Othello. Using Steve Mentz’s work with water and shipwreck, Lowell Duckert’s work on water in Shakespeare, Rob Nixon’s concept “slow violence,” Patricia Fumerton’s book on vagrancy in sixteenth and seventeenth century England, and Ken Hiltner’s work with environmental advocacy of the same time, I read the social history of vagrancy of the time (presented by Hiltner and Fumerton) alongside the Poor Laws. This social history is combined with water-focused ecocriticism, shipwreck and a postcolonial reading of migrancy. Ultimately, …

Assessing Historical Planform Channel Change In An Altered Watershed With Quantification Of Error And Uncertainty Present In A Gis/Aerial Photography-Based Analysis; Case Study: Minnesota River, Minnesota, Usa., Devon Libby

All Graduate Theses, Dissertations, and Other Capstone Projects

Little is known about the historic planform channel change of the Minnesota River of south-central Minnesota, USA. This is despite research that demonstrates anthropogenic activities have altered the Minnesota River Basin's hydrology, land use, and climate. In addition, the threat of invasive carp infestation requires an understanding of Minnesota River planform change to assess mitigation strategies. This thesis focuses on the lower Minnesota River (LMR) by measuring planform channel change (lateral channel migration, width, and sinuosity) from 1937 to 2013. Analysis is conducted by utilizing remote/GIS analysis of historic aerial photographs. A secondary focus addresses and quantifies the inherent/introduced error/uncertainly …

Necessary Conditions For Open-Ended Evolution, Lisa Soros

Electronic Theses and Dissertations

Evolution on Earth is widely considered to be an effectively endless process. Though this phenomenon of open-ended evolution (OEE) has been a topic of interest in the artificial life community since its beginnings, the field still lacks an empirically validated theory of what exactly is necessary to reproduce the phenomenon in general (including in domains quite unlike Earth). This dissertation (1) enumerates a set of conditions hypothesized to be necessary for OEE in addition to (2) introducing an artificial life world called Chromaria that incorporates each of the hypothesized necessary conditions. It then (3) describes a set of experiments with …

Transformative Youth Organizing: A Decolonizing Social Movement Framework, Emily Estioco Bautista

LMU Theses and Dissertations

The compounding experiences of colonial miseducation of youth of color, neoliberal policies and logics in urban communities, colonial logics that render the role of spirituality in social movements as invisible, and adultism in legal and social institutions constrain the transformative possibilities of youth agency in social movements. This study explored (a) how educators working in youth movements can build a decolonizing paradigm and practice for transformative organizing and (b) new paradigmatic interventions and theoretical directions that can help inform a transformative youth organizing approach. The research was conducted through a decolonizing interpretive research methodology (Darder, 2015a) and utilized the interrelated …

Bioethics & Vulnerability: Recasting The Objects Of Ethical Concern, Michael Thomson

Emory Law Journal

Mainstream bioethics has long been challenged for its focus on the technological developments of biomedicine and principles of individual ethics. It is argued that the focus on these particular objects, and the delisting of the social context within which the ethical is constructed and experienced, limits the extent to which bioethics provides a contesting counter-weight to modern biomedicine. In response, this Article promotes Martha Fineman¿s vulnerability theory as a new framework for bioethical deliberation. Fineman¿s foundational concern with the embodied and embedded experience of being human puts the social at the heart of analytical enquiry. Further, a focus on the …

Disturbance Of Redox Homeostasis In Down Syndrome: Role Of Iron Dysmetabolism, Eugenio Barone, Andrea Arena, Elizabeth Head, D. Allan Butterfield, Marzia Perluigi

Sanders-Brown Center on Aging Faculty Publications

Down syndrome (DS) is the most common genetic form of intellectual disability that leads in the majority of cases to development of early-onset Alzheimer-like dementia (AD). The neuropathology of DS has several common features with AD including alteration of redox homeostasis, mitochondrial deficits, and inflammation among others. Interestingly, some of the genes encoded by chromosome 21 are responsible of increased oxidative stress (OS) conditions that are further exacerbated by decreased antioxidant defense. Previous studies from our groups showed that accumulation of oxidative damage is an early event in DS neurodegeneration and that oxidative modifications of selected proteins affects the integrity …

Violence Exposure In Human Rights Defenders' Work, Marko Carrasco Lundgren

Capstone Collection

The work carried out by Human Rights Defenders (HRDs) is fundamental for a more just and democratic society. Therefore, the acts of aggression against them, whether committed by individuals, the State, armed groups or corporative interests, constitute an indirect attack against the rights of the whole population. By restricting access to information and limiting political participation, these aggressions impede society from actively engaging in public affairs, something that ultimately takes the power away from the people.

From a perspective empathetic to HRDs, this Independent Practitioner Inquiry Capstone paper (IPIC) explores possible causes of violence exposure in HRDs’ work and its …

Algae Biofuel Triacylglyceride Transesterification Optimization, Erik Ferenczy

Senior Honors Theses

Algae biofuels may hold the key to solving the problem of fossil fuel consumption by being comparable in content, renewable, and carbon-neutral. Many biofuel researchers and corporations have undertaken to increase the production rate or capacity of triacylglycerides (TAG), the fat precursor to biodiesel fuel produced by algae, in algae cultures and published articles documenting their findings. This research is devoted to evaluating the effect of water that may be present in samples on the conversion efficiency of TAG into fatty acid methyl esters (FAME), commonly referred to as biodiesel. Therefore, that efficiency was studied to find the water content …

1.5/2nd Generation Vietnamese-Americans And Their Health Beliefs And Attitudes, Theresa Dang

Pitzer Senior Theses

Vietnamese immigration is distinct from other Asian/Pacific Islander groups in its context – the bulk of Vietnamese immigration was not of educational, economic, or career opportunity, but a diaspora. After the Fall of Saigon during the Vietnam War, Vietnamese immigrants faced extreme adversities and trauma as they fled to neighboring countries. Understanding the context and history of Vietnamese immigration plays a huge role in the acculturation process, management of health, and ability to navigate institutions among these families. As these immigrant families learn to survive in a new country, they also must face and heal from the emotional, psychological, and …

Crystallographically Defined Silicon Macropore Membranes, Shannon C. Knight, Bret A. Unger, Kurt W. Kolasinski

Chemistry Faculty Publications

Laser ablation with nanosecond-pulsed Nd:YAG laser irradiation combined with anisotropic alkaline etching of Si wafers creates 4–20 µm macropores that extend all the way through the wafer. The walls of these macropores are crystallographically defined by the interaction of the anisotropy of the etchant with the orientation of the single-crystal silicon substrate: rectangular/octagonal on Si(001), parallelepiped on Si(110), triangular/hexagonal on Si(111). Laser ablation can create pillars with peak-tovalley heights of over 100 µm. However, with nanosecondpulsed irradiation at 532 nm, the majority of this height is created by growth above the original plane of the substrate whereas for 355 nm …

Plume And Nanoparticle Formation During Laser Ablation, Kurt W. Kolasinski, Mool C. Gupta, Leonid V. Zhigilei

Chemistry Faculty Publications

The processes that lead to material ejection when a solid sample is irradiated near and above the pulsed laser ablation threshold are discussed. Emphasis is placed on the thermal and mechanical mechanisms that occur during pulsed laser irradiation of metals and semiconductors. Distinctions are drawn between ultrafast-pulsed irradiation, which occurs under stress confinement, and shortpulsed irradiation, in which stress is released during the laser pulse. Similarly, the distinctions between the spallation and phase explosion regimes are discussed. Spallation is only possible when the time of the laser heating is shorter than the time needed for mechanical equilibration of the heated …

Hierarchical Porous Silicon And Porous Silicon Nanowires Produced With Regenerative Electroless Etching (Reetching) And Metal Assisted Catalytic Etching (Mace), Kurt W. Kolasinski, Bret A. Unger, Haibo Yu, Alexis T. Ernst, Mark Aindow, Ermei Mäkilä, Jarno Salonen

Chemistry Faculty Publications

ReEtching produces nanostructured silicon when a catalytic agent, e.g. dissolved V2O5, is used to facilitate etching between Si and H2O2. H2O2 regenerates dissolved V in a 5+ oxidation state, which initiates etching by injecting holes into the Si valence band. Independent control over the extent of reaction (controlled by the amount of H2O2 added) and the rate of reaction (controlled by the rate at which H2O2 is pumped into the etchant solution) allows us to porosify Si substrates of arbitrary size, shape and doping, including wafers, single-crystal powders, polycrystalline powders, metallurgical grade powder, Si nanowires, Si pillars and Si powders …

The mechanisms by which light can induce chemical reactions following electronic excitation are described. Processes reviewed include photodissociation of adsorbed molecules, photo-induced attachment of organic molecules and photo-induced corrosion.

The Heritage-Scape: Origins, Theoretical Interventions, And Critical Reception Of A Model For Understanding Unesco’S World Heritage Program, Michael A. Di Giovine

Anthropology & Sociology Faculty Publications

Written by the author of The Heritage-scape: UNESCO, World Heritage and Tourism (Lexington 2009), this article is a critical reflection of the heritage-scape concept nearly a decade after it was introduced in the literature. Including personal background stories that paint a picture of the intellectual origins and inspirations for the term, the article discusses the theory behind the heritage-scape, the concept’s contribution to the literature, and its reception by tourism and heritage theorists. As a theoretical buzzword meant to describe a particular, utopian model of the geopolitical order, it has nevertheless taken on a life of its own, and the …

The Folic Acid Metabolism Gene Mel-32/Shmt Is Required For Normal Cell Cycle Lengths In Caenorhabditis Elegans, Kalin D. Konrad, Raquel A. Campbell, Vanessa Thiel, Jessica Sullivan-Brown

Biology Faculty Publications

Neural tube defects are common and serious birth defects in which the brain and/or spinal cord are exposed outside the body. Supplementation of foods with folic acid, an essential vitamin, is linked to a lower risk of neural tube defects; however, the mechanisms by which folic acid influence neural tube defect risk are unclear. Our research seeks to identify the basic cellular roles of known folic acid metabolism genes during morphogenesis using the roundworm Caenorhabditis elegans (C. elegans) as a simple model system. Here, we used live imaging to characterize defects in embryonic development when mel-32 is depleted. mel-32 is …

Victim-Group Legitimacy: An Argument For Extending Our Understanding Of Legitimacy After Crisis, Cody Blake Wilson

International Crisis and Risk Communication Conference

Organizational legitimacy has been useful approach to studying relationship management in crisis. This presentation suggests an expansion of organizational legitimacy theory: victim-group legitimacy. Multiple recent cases of crisis involving historically marginalized groups (HMGs) suggest that organizations may not be fully prepared to respond to crises involving HMGs. Recent cases also suggest that publics now routinely see modern crises as chapters within larger marginalization narratives. Victim-group legitimacy acts as a framework for evaluating, interpreting, and responding to not only the crisis at hand, but the historical crisis between an organization and HMGs.

Impact Of Increased Green Turtle Nesting On Loggerhead Fitness, Amanda R. Carmichael

Honors Undergraduate Theses

Marine turtles exhibit strong fidelity to their nesting beaches, making the conservation of nesting beaches important for ensuring successful sea turtle populations. Conservation of these nesting beaches involves understanding how species interact with the environment and each other, and understanding how environmental change and population growth can affect the suitability of the nesting habitat. The Archie Carr National Wildlife Refuge (ACNWR) is unusual in its high density of sea turtle nesting by two species: green (Chelonia mydas) and loggerhead (Caretta caretta) turtles. The ACNWR in Melbourne Beach, Florida was established in 1991 due to the high density of loggerhead nesting, …
