  1. 11. Groundwater occurrence and quality in Bulawayo province, Zimbabwe

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anton Nygren; Edvard Nordenskjöld; Erik Östblom; [2016]
    Keywords : total dissolved solids; salinity; electrical conductivity; electrical resistivity tomography; vertical electrical sounding; magnetic field; auger holes; saturated hydraulic conductivity;

    Abstract : This study focused on determining the groundwater flow paths in the crystalline subsurface rocks of the Bulawayo metropolitan, Zimbabwe, through analysing the discontinuities of the electrical properties of the ground, as well as in the magnetic field of the underlying rocks. Further, borehole water quality was analysed by measuring and mapping several chemical parameters, specifically TDS, salinity and the electrical conductivity. READ MORE

  3. 12. Evaluation of DC resistivity and time-domain IP tomography for bedrock characterisation at Önneslöv, Southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Daniel Preis Bergdahl; [2016]
    Keywords : bedrock; Cole-Cole; resistivity; induced polarization; dyke; weathering; Earth and Environmental Sciences;

    Abstract : For both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. READ MORE

  4. 13. Spectral time domain induced polarization : factors affecting spectral data information content and applicability to geological characterization

    University essay from Lunds universitet/Geologiska institutionen

    Author : Azadeh Rezvani; [2015]
    Keywords : Liikavaar; geology; geophysics; resistivity; induced polarization; Aititk mine; AarhusInv; Earth and Environmental Sciences;

    Abstract : The geo-electrical survey (resistivity and induced polarization) with different settings, arrangements, time base, spreads and waveforms (50% and 100% duty cycle waveform) was carried out over the Liikavaara depo-sit, near the Aitik mine, in northern Sweden and all the measured data was inverted in two different softwares: Res2Dinv and AarhusInv. Surveys of induced polarization (IP) often contain data of low quality, due to the high sensitivity against noise sources and coupling effects. READ MORE

  5. 14. The application of resistivity and IP-measurements as investigation tools at contaminated sites : a case study from Kv. Renen 13, Varberg, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Sofia Åkesson; [2015]
    Keywords : geophysics; resistivity; induced polarization; contaminated site; hydrogeology; trichloroethene; TCE; Earth and Environmental Sciences;

    Abstract : An old industry estate, Kv. Renen 13, is located in central Varberg, southwest Sweden, and is known from previous investigations as highly polluted. READ MORE

  6. 15. Inducing Lasting Attitude Change Through Choice - A Choice Blindness Study on Political Views

    University essay from Lunds universitet/Kognitionsvetenskap

    Author : David Sivén; [2015]
    Keywords : confabulation; preference change through choice; preference change; decision making; choice blindness; Social Sciences; Science General;

    Abstract : Studies of decision-making have shown that attitudes can be influenced by choices. One way in which to study these types of attitude changes can be through the choice blindness paradigm. READ MORE
