  1. 1. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Axel Barrdahl; [2022]
    Keywords : Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Abstract : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. READ MORE

  3. 2. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

  4. 3. Estimating the probability of levee failure for flood risk mapping : An application to Paglia River

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Theodora Neromylioti; [2020]
    Keywords : Levee failure; inner erosion; piping; backward erosion; seepage; probability of failure; fragility curves; time-dependent failure; hydraulic modelling; flood risk; flood inundation; HEC-RAS;

    Abstract : Climate change results to more extreme and frequent flood events that induce extra risk to flood protection structures such as levees. Thus, estimation of the probability of levee failure is of utmost importance when it comes to structural safety and flood risk assessment. READ MORE

  5. 4. Finite Element Modeling of Skull Fractures : Material model improvements of the skull bone in theKTH FE head model

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Frida Andersson; [2016]
    Keywords : ;

    Abstract : The main aim of this project was to develop a model for predicting skull fractures of a 50th percentile male, using a finite element head model developed at the Neuronics department of KTH, Royal Instituteof Technology. The skull bone is modeled as a three layered bone, where the outer and inner tables are modeled as shell elements, while the diploë is modeled by two layers of solid elements. READ MORE

  6. 5. The Roots of a Magma Chamber, the Central Intrusion, Rum, NW-Scotland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tobias Mattsson; [2014]
    Keywords : Rum; Layered Ultrabasic Intrusion; Long Loch Fault; 3D modelling; Rum; Minerallagrad magmakammare; Long Loch Förskastningen; 3D modellering;

    Abstract : The island of Rum in the Inner Hebrides, NW-Scotland, hosts a central volcanic complex that is part of the British-Irish Palaeogene Igneous Province situated in NE- Ireland and NW- Scotland. On Rum, rocks from several stages of Palaeogene magmatic activity have been exposed by millions of years of erosion. READ MORE
