  1. 26. Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Nicte Polanco Olsen; [2018]
    Keywords : ;

    Abstract : I närvaro av fukt och lokaliserade fältförbättringar kan vattenträd utvecklas inom polymerisoleringen av HV subsea kraftkablar. Vattenträd tenderar att växa obemärligt och försämra isolationsegenskaperna med tiden. Fuktigheten i isoleringen kan effektivt reduceras genom applicering av halvledande svällningsband. READ MORE

  3. 27. Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Haoyu Wei; [2018]
    Keywords : Halogenated hydrocarbon; Geophysics; DCIP; GeoScene3D; Groundwater chemistry; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The Alingsås dry-cleaning facility is one of the heavily halogenated hydrocarbon contaminated sites in Sweden. The source of contamination dates back to the 1970s when a large scale tetrachloroethylene leakage outbroke inside the dry-cleaning building. READ MORE

  4. 28. Evaulation of liquid-exfoliatedgraphene as additive in Ag-basedsliding contacts

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Stina Juhlin; [2018]
    Keywords : liquid-exfoliated graphene; liquid exfoliated graphene; graphene; sliding contacts; additive in Ag-based sliding contacts; Raman; SEM; EDS; tribometer; liquid exfoliation; liquid phase exfoliation;

    Abstract : This master thesis work is performed at ABB Corporate Research Center inVästerås. The aim of this study is to investigate Ag:graphene composites as slidingelectrical contacts, suitable for use in e.g. tap-changers. READ MORE

  5. 29. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Hedda Jönsson; Anna Wiberg; [2017]
    Keywords : Chlorinated hydrocarbons; PCE; Hagforstvätten; Geophysics; Resistivity; Chargeability; Geological features; Man-made structures; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater plumes of PCE.

  6. 30. A geophysical survey (TEM; ERT) of the Punata alluvial fan, Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Joakim Mårdh; [2017]
    Keywords : electromagnetic; geophysics; TEM; Punata; alluvial fan; Earth and Environmental Sciences;

    Abstract : The Punata alluvial fan, situated in central Bolivia (Valle Alto) between the Altiplano and the lowlands, is an important aquifer for the local rural population. Due to rapid development and population growth in the area, the demand for fresh water has increased in recent year. READ MORE
