  1. 1. Hydrogen in nominally anhydrous silicate minerals : Quantification methods, incorporation mechanisms and geological applications

    Author : Franz A. Weis; Henrik Skogby; Peter Lazor; Jannick Ingrin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NAMs; clinopyroxene; hydrogen; hydrothermal pressure; magmatic water content; zoisite; OH-dipole; Raman spectroscopy; FTIR; luminescence; proton-proton scattering;

    Abstract : The aim of this thesis is to increase our knowledge and understanding of trace water concentrations in nominally anhydrous minerals (NAMs). Special focus is put on the de- and rehydration mechanisms of clinopyroxene crystals in volcanic systems, how these minerals can be used to investigate the volatile content of mantle rocks and melts on both Earth and other planetary bodies (e.

  2. 2. Kinh Settlers in Viet Nam’s Northern Highlands : Natural Resources Management in a Cultural Context

    Author : Mats Lundberg; Anders Hjort af Ornäs; Hans Holmén; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Viet Nam; northern mountains; highlands; wet rice agriculture; upland agriculture; shifting cultivation; natural resources use; local knowledge; culture; ethnicity; Naturresurser; Vietnam; etniska grupper; Water in nature and society; Vatten i natur och samhälle;

    Abstract : This study deals with the Kinh (or Viet) majority people who have migrated from the lowland Red River Delta to the mountainous areas of northern Viet Nam, and their adjustment to a new social and physical environment. Its aim is to analyse the social and cultural consequences for these migrants when settling in communities populated with people who belong to the national ethnic minorities (the Tày, the Giay and the Ngan peoples).

  3. 3. Water as a trace component in mantle pyroxene: Quantifying diffusion, storage capacity and variation with geological environment

    Author : Rickard Sundvall; Henrik Skogby; Alasdair Skelton; Eugen Libowitzky; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pyroxene; mantle mineralogy; water in nominally anhydrous minerals; iron redox-reaction; kinetics; water zonation; FTIR imaging; re-hydration capacity; Mineralogy; Mineralvetenskap; Mineralogy; Petrology and Geochemistry; mineralogi; petrologi och geokemi;

    Abstract : In this study, distribution and diffusion of water in pyroxene are examined in an effort to explain the water content variation observed in natural pyroxene. Water is a common trace component in many nominally anhydrous minerals (NAMs) from the Earth's crust and mantle and greatly impacts their physical properties. READ MORE

  4. 4. Structure-based Virtual Screening for Ligands of G Protein-coupled Receptors : Design of Allosteric and Dual-Target Modulators

    Author : Stefanie Kampen; Jens Carlsson; Peter Kolb; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptors; Polypharmacology; Molecular Docking; Structure-based Drug Design; Parkinson’s Disease; Virtual Screening; Allosteric Modulators; Bioinformatics; Bioinformatik;

    Abstract : G protein-coupled receptors (GPCRs) are integral membrane proteins responsible for signal transduction of extracellular stimuli into the cell. Because of their widespread distribution throughout the human body and important roles in physiological processes, GPCRs are prominent drug targets and approximately 34% of all approved drugs interact with members of this superfamily.

  5. 5. Novel Endpoints To Unravel Developmental Neurotoxicity : From DNA methylation responses to methylmercury to the in vitro identification of endocrine disruptors

    Author : Andrea Cediel-Ulloa; Joëlle Rüegg; Pamela J. Lein; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Developmental neurotoxicity; Methylmercury; DNA methylation; Endocrine disruptors; in vitro assay development; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Abstract : The developing brain is especially sensitive to environmental stressors due to its dependence on the precise spatiotemporal regulation of multiple signals, and the long time period required for its formation. Some chemicals can interfere with molecular and cellular processes driving brain development, including epigenetic processes such as DNA methylation. READ MORE
