(NTNU Vitenskapsmuseet arkeologisk rapport;, Research report, 2016)Rapporten omhandler analysearbeid, laboratorietester og feltarbeid knyttet til malingsfjerning på de oppmalte helleristningsfeltene Hell I og Bardal I i Nord-Trøndelag. Dette har vært en arbeidsprosess som har som mål å ... -
Laboratory and free-living gait performance in adults with COPD and healthy controls
(Peer reviewed; Journal article, 2023)Background Gait characteristics are important risk factors for falls, hospitalisations and mortality in older adults, but the impact of COPD on gait performance remains unclear. We aimed to identify differences in gait ... -
Laboratory Characterisation of a Commercial RGB CMOS Camera for Measuring Night Sky Brightness
(Peer reviewed; Journal article, 2023)The use of RGB cameras in photometric applications has grown over the last few decades in many fields such as industrial applications, light engineering and the analysis of the quality of the night sky. In this last field, ... -
Laboratory Evaluation of Static and Dynamic Sag in Oil-Based Drilling Fluids
(Journal article; Peer reviewed, 2020)In this paper, we present the results of barite sag measurements before and after hot-rolled oil-based drilling fluids (OBDFs) using different approaches for characterization. We characterized the barite sag of a liquid ... -
Laboratory experiments on shared-energy collisions between freshwater ice blocks and a floating steel structure
(Journal article; Peer reviewed, 2017)Ship collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. ... -
Laboratory experiments on ultrasonic logging through casing for barrier integrity validation
(Chapter, 2017)Verification of annular barriers is essential for well integrity, with ultrasonic methods being central in well integrity testing for many decades. By doing ultrasonic pitch-catch measurements on a bench top laboratory ... -
Laboratory Investigation of Impact of Injection–Abstraction Rate and Groundwater Flow Velocity on Groundwater Heat Pump Performance
(Peer reviewed; Journal article, 2023)Using low-temperature (shallow) groundwater as a heat source or heat sink is a common practice to supply space heating or cooling, especially in the United States, Canada, China, and several European countries. The groundwater ... -
Laboratory investigation of performance of a screen type debris-flow countermeasure
(Journal article; Peer reviewed, 2018)Debris-flows are forms of landslides in mountainous regions that can potentially cause significant damage. Structural countermeasures to mitigate an entire debris-flow may become unrealistically massive and expensive. If ... -
Laboratory investigations of moisture conditions in wood frame walls with wood fiber insulation
(Peer reviewed; Journal article, 2015)The purpose of this study was to investigate the moisture conditions in wood frame walls with wood fiber thermal insulation in a Nordic climate. Laboratory measurements were conducted on 15 different wall configurations. ... -
Laboratory Measurements of Strength Parameters for Fracturing
(Chapter, 2017)Fracture toughness and tensile strength are rock parameters that have influence on hydraulic fracture initiation and propagation, and that to various degrees are implemented in fracture modeling tools. Laboratory measurements ... -
Laboratory study of ice floes collisions under wave action
(Journal article; Peer reviewed, 2018)This paper examines the experimental data on ice floes collisions from the HYDRALAB+ Transnational Access project: Loads on Structure and Waves in Ice (LS-WICE). The paper quantifies the contribution from ice-floes collisions ... -
Laboratory study of plugging mechanism and seal integrity in fractured formations using a new blend of lost circulation materials
(Peer reviewed; Journal article, 2023)The problem of lost circulation occurred long during the drilling operation. Through induced and natural fractures, huge drilling fluid losses lead to higher operating expenses during the drilling. Historically, this problem ... -
Laboratory study of wave-induced flexural motion of ice floes
(Peer reviewed; Journal article, 2021)Wave-ice interactions involve complex physical processes. Well-designed laboratory investigations are indispensable for studying these processes. In the present study, laboratory experimental data on saline ice obtained ... -
