A hybrid of 1-deoxynojirimycin and benzotriazole induces preferential inhibition of butyrylcholinesterase (BuChE) over acetylcholinesterase (AChE)
(Peer reviewed; Journal article, 2022)The synthesis of four heterodimers in which the copper(I)-catalysed azide-alkyne cycloaddition was employed to connect a 1-deoxynojirimycin moiety with a benzotriazole scaffold is reported. The heterodimers were investigated ... -
Hybridization of gradient-based and gradient-free optimization techniques for simultaneous optimization of number of wells, their location and drilling time in a 2-dimensional reservoir
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Optimization has always been a challenging scope in any field of science, and reservoir management is no exception. By the advent of computational power, the use of mathematical algorithms in conjunction with reservoir ... -
Hydrate growth kinetics: A study on the relation between energy release rates and gas consumption rates during methane hydrate formation and growth.
(Masteroppgave/UIS-TN-IØRP/2013;, Master thesis, 2013)The relation between mass transfer, energy transfer and growth rates has been examined during methane hydrate formation in stirred cell reactors. This was done to improve understanding rate determining factors during hydrate ... -
Hydrate nucleation kinetics and statistical analysis of experimental data
(Master thesis, 2014-06-16)The effect on accuracy of reducing the number of experiments in the series has been investigated on isochoric, constant temperature nucleation experiments. In addition, data from two other nucleation studies have been ... -
Hydrate plugs in subsea pipelines and non-invasive methodology for localization
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)With the growth in global energy demand and the lack of new shallow-water and onshore opportunities, there is growing emphasis on oil and gas production in deep-water environments. A particular challenge for flow assurance ... -
Hydraulic Behavior in Cased and Open Hole Sections in Highly Deviated Wellbores
(Chapter, 2019)In this paper we present results from flow loop experiments with an oil-based drilling fluid with micronized barite as weight materials. The use of micronized barite allows using lower viscosity drilling fluid, providing ... -
Hydraulic Behaviour: A Tracer Study of a Stormwater Detention and Sedimentation System
(Master thesis, 2023)Stormwater is of growing concern with increased heavy rainfall and runoff surfaces from urbanisation. The challenges of stormwater has two aspects; risk of flooding and risk of pollution. Road runoff in particular, can at ... -
Hydraulic calculations using discovery web for visualization
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-15)Advanced real-time monitoring systems are useful tools for safe and cost effective well operation practices. As one moves into deeper water, higher pressure and higher temperature, the drilling operations only becomes more ... -
Hydrodynamic analysis of drill string in open water
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)Due to a decline in proven petroleum reserves through continued production, exploration of oil and gas has moved into more challenging environment and into deep and ultra-deep water. Over the years, the equipment and ... -
Hydrodynamic oscillations of non-newtonian fluids in u-tube
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-16)In this thesis, a five meter high flow rig has been constructed in the form of a U-tube. Several experiments were conducted in order to investigate rheological parameters in an oscillating flow with the intention of gaining ... -
Hydrodynamic performance optimization of semi-submersible floaters for offshore wind turbines
(Master thesis, 2022)Floating structures have become viable alternatives for supporting wind turbines as offshore wind projects move deeper into the water. The wind is prevalent in deep water (depths > 60 m) all around the world. Because of ... -
Hydrodynamization in systems with detailed transverse profiles
(Peer reviewed; Journal article, 2020)The observation of fluid-like behavior in nucleus-nucleus (AA), proton-nucleus (pA) and high-multiplicity proton-proton (pp) collisions motivates systematic studies of how different measurements approach their fluid-dynamic ... -
Hydrogen diffusion into caprock: A semi-analytical solution and a hydrogen loss criterion
