  1. 1. Iron and Oxygen Isotope Signatures of Magnetite in Iron Ore of Kiruna Type

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Malin Andersson; [2020]
    Keywords : IOA-deposits; magnetite; SIMS; EBSD; Fe- and O isotopes; laser fluorination;

    Abstract : Stable isotope analysis of iron and oxygen isotopes in magnetite of Kiruna-type from Sweden and Chile have been conducted to further the understanding of the formation, and advance the analysis methods of these deposits. For this, data from SIMS (secondary ion mass spectroscopy), EBSD (electron backscatter diffraction) and triple oxygen analysis (by laser fluorination) are used. READ MORE

  2. 2. A physical accounting model for monitoring material flows in urban areas with application to the Stockholm Royal Seaport district

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Asterios Papageorgiou; [2018]
    Keywords : Urban Metabolism; Physical Input Output Table; Material Flow Analysis; Stockholm Royal Seaport; Bottom-up data;

    Abstract : There is a plethora of methods and tools that can be used for the assessment of Urban Metabolism. Nevertheless, there is no standardized method for accounting of material flows within and across the boundaries of urban systems. READ MORE

  3. 3. ASSESSMENT OF LEAD AND CADMIUM LOADING IN THE WATER RESOURCES OF KINGSTON, JAMAICA : An application of input-output assessment modelling

    University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Khafi Weekes; [2010]
    Keywords : lead; cadmium; hydrology; Jamaica; Caribbean; water resources; input-output assessment;

    Abstract : Input-Output Assessment (IOA) was employed to quantify a likely range of annual lead and cadmium fluxes and to discern their possible flow paths in the water system of the Kingston hydrological catchment in south-eastern Jamaica. This technique was useful to understand how cross-sectoral mass exchanges of these heavy metals ultimately impacted the water resources of the basin. READ MORE

  4. 4. Globalized impacts International trade accounting in a hybrid LCI method

    University essay from

    Author : Damien Arbault; [2009]
    Keywords : LCA; LCI; IHA; IOA; hybrid method; globalized impacts; international trade;

    Abstract : Life-Cycle Assessment (LCA) covers a set of tools and techniques that aim to estimate the environmental impacts generated by a product or service all along its life-cycle including: rawmaterial extraction, production steps, transportation, use phase and end-of-life scenarios.The Life-Cycle Inventory (LCI) is a key step in LCA.

  5. 5. Capacitive pH-Sensors using pH sensitive polymer

    University essay from

    Author : Krishna Chytanya Chinnam; [2009]
    Keywords : Capacitive pH Sensors; pH Sensors; Capacitive Sensors Sensors.;

    Abstract : This project aims in building a new experimental setup for capacitive measurements of a pH-Sensor. PAA-IOA (Poly Acrylic Acid co – Iso Octyl Acrylate) is the dielectric material over the in-plane interdigitated gold electrodes where PAA IOA acts as an H+ ion sensing layer. READ MORE
