  1. 1. Geophysical investigation of the Arvidsjaur volcanics and the Archean-Proterozoic boundary

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Erik Bjänndal; [2019]
    Keywords : Laver SimPEG MT Magnetotelluric Magnetic Inversion;

    Abstract : In this work the magnetic and magnetotelluric (MT) geophysical methods have been used to produce two 3D models for the Laver area in southern Norrbotten. A new discovery of a porphyry copper deposit located at the Lill-Laverberget was reported by Boliden in 2012. READ MORE

  2. 2. Direct poly(A) RNA nanopore sequencing on the freshwater duck mussel Anodonta anatina following exposure to copper : A pilot study

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Erik Engström; [2019]
    Keywords : mussel; hepatopancreas; nanopore; sequencing; RNA; nucelotide; read;

    Abstract : Aquatic ecotoxicology is the study of toxic chemicals and its effects on aquatic biological systems with the aim of minimising threats to human health and ensure self-sustained ecosystems. Freshwater bivalves are excellent sentinels for use in ecotoxilogical research due to their filter feeding properties, stationary lifestyle and inability to regulate body temperature. READ MORE

  3. 3. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  4. 4. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    University essay from Lunds universitet/Kemiska institutionen

    Author : Niklas Gunnarsson; [2019]
    Keywords : Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Abstract : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. READ MORE

  5. 5. Prototype manufacturing of microwave components using plastic 3D printing

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Björn Malmquist; [2019]
    Keywords : ;

    Abstract : The ability to easily customize and produce specialized MW-components for research and industry is a real challenge and the need is identified, as standardized parts have limited use and can limit design freedom. This study aims at exploring if there are simple ways to manufacture rectangular X-band waveguides with operating frequency of 8-12GHz with novel polymer additive manufacturing and chemical metal deposition that can match Computer Numerical Control (CNC) manufactured rectangular metal waveguides in performance.
