AVO Modelling Considering Various Caprock and Reservoir Scenarios for Potential CO2 Storage in Smeaheie Area, Northern North Sea
(Chapter, 2019)We have performed a comparative study of undrained triaxial testing with five different laboratories, to explore the reproducibility of test results. Opalinus Clay was sourced as testing material from a borehole at the ... -
Back-Calculation of Element Tests with a Rate Dependent Soft Soil Model
(Chapter, 2016)It is well known that soft clays are geo-materials with properties such as fabric, bonding and rate-dependency. The response observed when modelling complex boundary value problems will depend on the ability of the soil ... -
Behavior and Critical Failure Modes of Strip Foundations on Slopes under Seismic and Structural Loading
(Peer reviewed; Journal article, 2019)This paper presents a numerical study on capacity envelopes of strip foundations placed on the top and the face of two typical soil slopes at different offset distances and subjected to earthquake effects using the ... -
Behavior of slopes under multiple adjacent footings and buildings
(Peer reviewed; Journal article, 2018)This article examines the response of soil slopes under adjacent embedded strip foundations, subjected to increasing vertical load due to the gravity load of buildings. The study also considers slopes under closely spaced ... -
Benchmark study of undrained triaxial testing of Opalinus Clay shale: Results and implications for robust testing
(Peer reviewed; Journal article, 2020)Triaxial testing of argillaceous rocks and shales is significantly more challenging than conventional rock mechanical testing. The challenges are mainly related to the very low permeability of these geomaterials, and their ... -
Bestemmelse av hviletrykk (K0) i norske leirer – anbefalinger basert på en sammenstilling av lab-, felt- og erfaringsdata
(Chapter, 2017)The purpose of this study is to present guidelines and correlations to estimate the coefficient of earth pressure at rest (K0) in Norwegian clays in absence of site-specific data. A database of K0-measurements from advanced ... -
Bioaccumulation of Fluorotelomer Sulfonates and Perfluoroalkyl Acids in Marine Organisms Living in Aqueous Film-Forming Foam Impacted Waters
(Peer reviewed; Journal article, 2019)The use of aqueous film-forming foams (AFFFs) has resulted in hot spots polluted with poly- and perfluorinated alkyl substances (PFASs). The phase out of long-chained perfluoroalkyl acids (PFAAs) from AFFFs resulted in the ... -

(Peer reviewed; Journal article, 2019)The use of aqueous film-forming foams (AFFFs) has resulted in hot spots polluted with poly- and perfluorinated alkyl substances (PFASs). The phase out of long-chained perfluoroalkyl acids (PFAAs) from AFFFs resulted in the ... -
Bioactive Metabolites of Marine Origin Have Unusual Effects on Model Membrane Systems
(Peer reviewed; Journal article, 2020)Marine sponges and soft corals have yielded novel compounds with antineoplastic and antimicrobial activities. Their mechanisms of action are poorly understood, and in most cases, little relevant experimental evidence is ... -
Biochar amendment improves degraded pasturelands in Brazil: environmental and cost-benefit analysis
(Peer reviewed; Journal article, 2019)Most deforested lands in Brazil are occupied by low-productivity cattle ranching. Brazil is the second biggest meat producer worldwide and is projected to increase its agricultural output more than any other country. Biochar ... -
Biochar Effect on Maize Yield and Soil Characteristics in Five Conservation Farming Sites in Zambia
(Journal article, 2013)Biochar addition to agricultural soils can improve soil fertility, with the added bonus of climate change mitigation through carbon sequestration. Conservation farming (CF) is precision farming, often combining minimum ... -
Biochar from "Kon Tiki" flame curtain and other kilns: Effects of nutrient enrichment and kiln type on crop yield and soil chemistry
(Peer reviewed; Journal article, 2017)Biochar application to soils has been investigated as a means of improving soil fertility and mitigating climate change through soil carbon sequestration. In the present work, the invasive shrub "Eupatorium adenophorum" ... -
Biochar improves maize growth by alleviation of nutrient stress in a moderately acidic low-input Nepalese soil
(Peer reviewed; Journal article, 2018)We studied the role of biochar in improving soil fertility for maize production. The effects of biochar on the alleviation of three potential physical-chemical soil limitations for maize growth were investigated, i.e. water ... -
Biologiske prosesser i sedimenter – en litteraturstudie
(Bioforsk Rapport, Research report, 2006)På bakgrunn av St. meld. nr. 12 ”Rent og rikt hav”, hvor forurensede sedimenter i kyst og fjordområder fikk stor oppmerksomhet, er det nå planlagt en rekke tiltak langs norskekysten. Enkelte av tiltakene innebærer at ... -
Brief communication "Landslide Early Warning System: toolbox and general concepts"
(Journal article, 2013)We define landslide Early Warning Systems and present practical guidelines to assist end-users with limited experience in the design of landslide Early Warning Systems (EWSs). In particular, two flow chart-based tools ... -
Building damage due to vibration from rock blasting
(Peer reviewed; Journal article, 2020)Construction activities such as blasting, piling, compaction, excavations, and construction traffic can produce vibrations of sufficient strength to cause damage to neighbouring buildings and structures. Therefore, many ... -
Building Deformation Caused by Tunneling: Centrifuge Modeling
(Peer reviewed; Journal article, 2020)This paper investigates the deformation of buildings due to tunneling-induced soil displacements. Centrifuge model tests of three-dimensionally (3D) printed building models subject to a plane-strain tunnel excavation in ...
