Relationships between Isomeric Metabolism and Regioselective Toxicity of Hydroxychrysenes in Embryos of Japanese Medaka (Oryzias latipes)
(Peer reviewed; Journal article, 2022)Oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) are ubiquitous contaminants that can be formed through oxidation of parent PAHs. Our previous studies found 2-hydroxychrysene (2-OHCHR) to be significantly more toxic ... -
Modelling fire occurrences in heavy goods vehicles in road tunnels
(Peer reviewed; Journal article, 2022)The project reported in this paper has been organized to scrutinize current incident data on near fires and fully developed fires in Norwegian road tunnels longer than 500 m. This length is chosen because it is assumed ... -
Arctic supply chain reliability in Baffin Bay and Greenland
(Peer reviewed; Journal article, 2022)Despite the obvious economic advantages of utilising supply chains across the northern routes, there are significant challenges to their reliability. Every year an increasing number of ships venture into the region to ... -
A risk-increasing safety strategy? Evaluating the Traditional Risk-mitigating Strategy in Dealing with Dumped Ammunition and Explosive Remnants of War
(Peer reviewed; Journal article, 2022) -
Risk understanding and risk acknowledgement : a new approach to environmental risk assessment in marine aquaculture
(Peer reviewed; Journal article, 2022)A better understanding of the potential cumulative impacts of large-scale fish farming, could help marine aquaculture to become more environmentally sustainable. Risk assessment plays an important role in this process by ... -
Linear quadratic regulator optimal control of two-rotor wind turbine mounted on spar-type floating platform
(Peer reviewed; Journal article, 2022)Interest is steadily growing for multi-rotor wind turbine concepts. This type of wind turbine offers a practical solution for scaling issues of large wind turbine components and for the reduction of costs associated with ... -
A risk science perspective on liability/guilt and uncertainty judgements in courts
(Peer reviewed; Journal article, 2022)This article aims to provide new insights about risk and uncertainty in law contexts, by incorporating ideas and principles of contemporary risk science. The main focus is on one particular aspect of the law: its operation ... -
Heterotic quantum cohomology
(Peer reviewed; Journal article, 2022-11)It is believed, but not demonstrated, that the large radius massless spectrum of a heterotic string theory compactified to four-dimensional Minkowski space should obey equations that split into ‘F-terms’ and ‘D-terms’ in ... -
NewbornTime - improved newborn care based on video and artificial intelligence - study protocol
(Journal article, 2023)Background Approximately 3-8% of all newborns do not breathe spontaneously at birth, and require time critical resuscitation. Resuscitation guidelines are mostly based on best practice, and more research on newborn ... -
Nonlinear fatigue life prediction model based on the theory of the S-N fatigue damage envelope
(Peer reviewed; Journal article, 2022)A nonlinear model is proposed in light of the theory of isodamage curves, to assess the cumulative fatigue damage under multistage loading. The isodamage curves were developed through the theory of the S-N fatigue damage ... -
The effect of temperature on CO2 injectivity in sandstone reservoirs
(Peer reviewed; Journal article, 2022)Carbon Capture, Utilization and Storage (CCUS) is a pragmatic technology that could reduce anthropogenic CO2 and halt climate change. CO2 injectivity is affected by several physicochemical interactions around the injection ... -
Towards using Thermal Cameras in Birth Detection
(Chapter, 2022)In recent years, thermal imaging has been used in numerous applications due to its ability to capture and visualize the thermal radiation emitted by objects. Thermal cameras can be employed as non-invasive systems for ... -
Stochastic modeling and financial viability of mollusk aquaculture
(Peer reviewed; Journal article, 2022)Compared to finfish and crustaceans, limited attention has been given to the economic modeling and production risk analysis of mollusk aquaculture. Given mollusk aquaculture's sensitivity to environmental factors, understanding ... -
Application of non-parametric statistical methods to predict pumpability of geopolymers for well cementing
(Peer reviewed; Journal article, 2022)As a potential alternative to Portland cement, geopolymers are getting wider acceptance in the scientific world. On a laboratory scale, the latter is being experimented repeatedly to extract valuable and valid results. To ... -
Characterization of the mud displacement in an enlarged wellbore: An integrated rock-fluid model
(Peer reviewed; Journal article, 2022)Cement-mud displacement plays a crucial role in the sealability of cement sheaths. Irregular geometric features of a wellbore due to washout can have a negative impact on mud and cement mobilization. An unstable interface ... -
Virtual Sensors and Actuators
(Chapter, 2021)This chapter introduces the design of virtual sensors and actuators using the classical eigenvalue assignment approach, widely used for the design of controllers and observers in state-space. It presents a linear matrix ... -
Computational investigation of the aerodynamic performance of reversible airfoils for a bidirectional tidal turbine
(Peer reviewed; Journal article, 2021)A reversible airfoil is an airfoil that has equal performance when the flow is reversed. Such airfoils are relevant for many different applications, including use in ventilation fans, helicopter rotors, wind turbines and ... -
Second-Order PDEs in 3D with Einstein–Weyl Conformal Structure
(Peer reviewed; Journal article, 2021)Einstein–Weyl geometry is a triple (D,g,ω) where D is a symmetric connection, [g] is a conformal structure and ω is a covector such that ∙ connection D preserves the conformal class [g], that is, Dg=ωg ; ∙ trace-free part ... -
