A U-Pb age for the Late Caledonian Sperrin Mountains minor intrusions suite in the north of Ireland: timing of slab break-off in the Grampian terrane and the significance of deep-seated, crustal lineaments
(2013)An intrusion of trachy-andesite, representative of a newly discovered suite of high-K–Ba–Sr, calc-alkaline minor intrusions (termed herein the Sperrin Mountains suite), hosted within the Grampian terrane in the north of ... -
U-Pb and Th-Pb dating of apatite by LA-ICPMS
(2011)Apatite is a common U- and Th-bearing accessory mineral in igneous and metamorphic rocks, and a minor but widespread detrital component in clastic sedimentary rocks. U-Pb and Th-Pb dating of apatite has potential application ... -
U-Pb LA-ICPMS dating using accessory mineral standards with variable common Pb
(2014)Precise and accurate U?Pb LA-ICPMS dating of many U-bearing accessory minerals (e.g. apatite, allanite, titanite and rutile) is often compromised by common Pb. LA-ICPMS dating of these U-bearing accessory phases typically ... -
U-Pb zircon ages for Yarlung Tsangpo suture zone ophiolites, southwestern Tibet and their tectonic implications
(2015)Ophiolite complexes preserved along the Yarlung Tsangpo suture zone (YTSZ) and obducted onto the northern continental margin of India in southern Tibet represent the remnants of the once extensive Permian–Mesozoic Neo-Tethyan ... -
Understanding late Holocene woodland dynamics in southwestern and western Ireland through the analysis of sub-fossil insect remains
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The main aim of this research was to explore the validity of using sub-fossil insect remains as a proxy for reconstructing late Holocene woodland dynamics in southwestern and western Ireland. Three woodlands were examined ... -
Understanding leakage from a fault-sealed CO2 reservoir in east-central Utah: a natural analogue applicable to CO2 storage
(Trinity College (Dublin, Ireland). Department of Geology, 2006)This thesis investigates a natural CO2 reservoir to define the factors that can cause leakage and determine the rates and consequences of CO2 leakage on the surrounding environment. Situated at the northern end of the ... -
Understanding the Lived Experiences of Gender Minority Students in Irish Third-Level Education
(Trinity College Dublin, 2019)This report provides the main analytical results of a survey distributed to gender minority students (i.e. transgender, non-binary, and gender non-conforming) in Irish higher education (Third-Level). The survey touched ... -
Understanding the Lived Experiences of Gender Minority Students in Irish Third-Level Education: Steps Towards Achieving Safety and Inclusion
(National LGBTQI Federation (NXF), 2020)This policy brief provides an overview of the findings in “Understanding the Lived Experiences of Gender Minority Students in Irish Third-Level Education: A National Survey of Transgender, Non-Binary, and Gender Non-Conforming ... -
Understanding variation in ecology and physiology of marine migratory species.
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)As the world faces the threats of multiple compounded and worsening crises, scientists are racing to gather the knowledge necessary to safeguard entire ecosystems and species. Technological advances are continuously ... -
Uneven development and the third space in the urban system : evidence from Dublin
(Trinity College (Dublin, Ireland). Department of Geography, 2001)The objective of this study is to contribute to the understanding of urban social change through theoretical-empirical exploration of the third space in the city. To achieve this, the research examines some aspects of the ... -
A Unified Theoretical Framework of Learning Theories to Inform and Guide Public Health Continuing Medical Education Research and Practice
(2021)Continuing medical education (CME) emerged at the start of the 20th century as a means of maintaining clinical competence among health care practitioners. However, evidence indicates that CME is often poorly developed and ... -
Unifying the Irish Vertical Datum with the Normaal Amsterdams Peil (NAP)
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)The local gravity potential value on Malin-Head tide gauge station in Ireland is derived from gravimetric and geometric geoid undulations. The geometric geoid undulations are obtained from GNSS and levelling data. In ... -
Unsaturated zone travel time to groundwater on a vulnerable site
(2005)A bromide (Br) tracing experiment was conducted to ascertain unsaturated zone travel time to groundwater on a site with a karstified limestone aquifer overlain by a thin free-draining overburden. Br tracer was applied to ... -
Uranium-lead geochronology applied to pyrope garnet with very low concentrations of uranium
(2023)We present U–Pb dates from peridotitic pyrope-rich garnet from four mantle xenoliths entrained in a kimberlite from Bultfontein, South Africa. Garnet dates magmatic emplacement due to the high mantle residence temperatures ... -
Urban conservation in a comparative perspective : Dublin and Stockholm
(Trinity College (Dublin, Ireland). Department of Geography, 2003)This thesis explores differing approaches to urban conservation in the cities of Dublin and Stockholm. It examines the impact of Central Government policies that have addressed directly or had indirect impact upon urban ... -
Urban Food Sharing
(Policy Press, 2019)This book explores the history and current practice of food sharing. Illustrated by rich case studies from around the world, the book uses new empirical data to set an agenda for research and action. The book will ... -
Urban transformation with TURAS open innovations; opportunities for transitioning through transdisciplinarity
(2016)Transitioning is a unidirectional process of mainstreaming sustainability within normative societal behaviour, which communities hope will build resilience, reduce our dependence on distant resources and lead to the ...
