(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2024)For their sensitivity to environmental variables, their impact on early developmental processes and their importance to the establishment of multiple phenotypes, epigenetic mechanisms have been increasingly studied during the last decades. Like ... -
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2024-06-27)This thesis explores two topics in three-dimensional gravity, the $\ttb$ deformation and zeta functions of three-dimensional quotient manifolds. The $\ttb$ deformation is an irrelevant deformation of a two-dimensional translationally invariant ...

(University of Iceland, School of Humanities, Faculty of Icelandic and Comparative Cultural Studies, 2024)The current thesis presents three published articles on inflectional change in Insular Nordic (Icelandic and Faroese). Papers I and II deal with change in Icelandic, while Paper III focuses on Faroese. The three articles are related through employment ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2024-06)The ΛCDM model is the most widely accepted model of cosmological structure formation and evolution. It includes a form of Cold Dark Matter (CDM), which is non-quantum, nonrelativistic and collisionless. It settles into extended and dense self-gravitating ...

(Springer Science and Business Media LLC, 2023-03-28)The geological setting of Iceland is unusual, with highly jointed rock mass, loose sediments created in glacial outburst floods and eruptions, and layers of lava-rock embedded in or overlying soft sediments. This study aims to assess the feasibility ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2024-06)The colonisation of a forest-forming tree species into an early successional environment, following long-distance dispersal, presents a unique opportunity to study the dynamics of a founder population in a setting that differs from its origin. This ...

(University of Iceland, School of Health Sciences, Faculty of Medicine, 2024-05-31)Exposure to adverse childhood experiences (ACEs), including abuse, neglect and growing up in dysfunctional home environments, has consistently been associated with an elevated risk of multiple negative mental health outcomes extending into adulthood. Yet, ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2024-05)In recent years seaweed has gained popularity as a health food due to its high content of minerals and vitamins. However, seaweeds may also accumulate high levels of potentially toxic elements – in particular arsenic, which may become incorporated ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2024-05)Population numbers result from the combined effect of exogenous (weather, food, predation, anthropogenic impact) and endogenous (behaviour, density) factors on the population, which often act simultaneously resulting in spatial variation in population ...
-
(University of Iceland, School of Health Sciences, Faculty of Nursing and Midwifery, 2024-05-23)As the global population ages, the prevalence of dementia is on the rise, making it a reality for many families worldwide to care for a relative living with dementia at home. It is generally acknowledged globally that providing care for a person living ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2024-05-24)Vanadium sesquioxide, typified by its first-order metal-insulator transi- tion, structural phase transition, and magnetic changes, transition from a high-temperature rhombohedral metallic and paramagnetic state to a low- temperature insulating monoclinic ...
