Friction reduction by using nanoparticles in oil-based mud
(Master thesis, 2014)Nowadays, increasing demand on petroleum resources and depletion of easy accessible reservoirs result in exploration of challenging reservoirs. Drilling of deeper reservoirs is an important part of this challenge where ... -
Friction stir welding/processing of mg-based alloys: A critical review on advancements and challenges
(Peer reviewed; Journal article, 2021)Friction stir welding (FSW) and friction stir processing (FSP) are two of the most widely used solid-state welding techniques for magnesium (Mg) and magnesium alloys. Mg-based alloys are widely used in the railway, aerospace, ... -
Friction vs. Area Scaling of Superlubric NaCl-Particles on Graphite
(Journal article; Peer reviewed, 2019)Structural lubricity is an intriguing tribological concept, where extremely low friction is anticipated, if two surfaces in relative motion do not share the same lattice structure and consequently instabilities originating ... -
Friction welding of selective laser melted Ti6Al4V parts
(Journal article; Peer reviewed, 2017)Ti6Al4V alloy samples fabricated by selective laser melting (SLM) were subjected to solid-state welding friction welding (FW). The welded alloy exhibits a α´-martensitic microstructure in the form of platelets with dimensions ... -
Friction, facts and fiction: Hybridity in Jean Potocki’s ‘Oriental’ travelogues
(Chapter; Peer reviewed, 2015) -
Frictional fluid instabilities shaped by viscous forces
(Peer reviewed; Journal article, 2023)Multiphase flows involving granular materials are complex and prone to pattern formation caused by competing mechanical and hydrodynamic interactions. Here we study the interplay between granular bulldozing and the stabilising ... -
Frictional Pressure Drop for Two-phase Flow of Carbon Dioxide in a Tube: Comparison between Models and Experimental Data
(Journal article; Peer reviewed, 2014)We compare models for two-phase frictional pressure drop with experimental data for pure CO2 taken in a tube of 10 mm inner diameter. The flow was nearly adiabatic, and the mass fluxes ranged from 1058 to 1663 kg/(m2 s), ... -
Frictional Pressure vs. Rheological Models
(Master thesis, 2010)When the drilling fluid leaves the mud pump, it circulates through the stand pipe, rotary hose, swivel, Kelly, drill pipe, drill collar, bit and the annulus between the drill string and the open hole or the casing. During ... -
Frictional pressure-drop models for steady-state and transient two-phase flow of carbon dioxide
(Master thesis, 2012)Related to the technology of CO2 capture, transport, and storage (CCS), an accurate transport model which predicts the behaviour of carbon-dioxide mixtures during steady-state and transient situations, is needed. A correct ... -
Frictions in the bioeconomy? A case study of policy translations and innovation practices
(Peer reviewed; Journal article, 2021)Building on a case study of a strategic funding initiative for biotechnology research and innovation, the paper analyses how policy objectives concerning innovation and value creation are responded to within the practices ... -
FRIDA App
(Bachelor thesis, 2019)FRIDA appen skal erstatte og forbedre en allerede eksisterende app og gjøre det lettere for frivillige og ansatte å bruke FRIDA i hverdagen. Systemet FRIDA består i forkant av oppgaven av flere moduler, blant annet en ... -
Frida Hansen og Nordenfjeldske Kunstindustrimuseum
(Bachelor thesis, 2021)BAKGRUNN Nordenfjeldske Kunstindustrimuseum har en stor samling av tekstilkunst og har stolte vevetradisjoner. I denne bacheloroppgaven er det tatt utgangspunkt i Frida Hansens billedvev Pioner (1901) som er en del av ... -
Friday on my mind: Re-assessing the Impact of Protest Size on Government Concessions
(Journal article; Peer reviewed, 2022)Do more protesters on the streets make governments likely to grant their demands? Several studies link protest size and government concessions. Yet existing research has limitations: many studies suffer from potential ... -
Fridtjof Nansens operasjonelle kode - En analyse og sammenlikning av Nansens og president Wilsons politiske personligheter
(Master thesis, 2022)Fridtjof Nansen er kjent som et komplekst menneske med sprikende karakteristikk og egenskaper, men hva kan man si om hans politiske personlighet? I denne oppgaven utsetter jeg Nansen for den operasjonelle kodeanalysen for ... -
Frie lette kjeder i serum hos myelomatose pasienter – metodesammenlikning av Freelite fra The Bindingsite, N Latex FLC og ELISA fra Sebia
(Bachelor thesis, 2020)Målet med denne oppgaven var å gjennomføre en metodesammenlikning mellom tre immunologiske metoder som benyttes for måling av frie, lette immunglobulinkjeder. Riktig kvantitering av frie, lette immunglobulinkjeder er viktig ... -
Friedel's salt profiles from thermogravimetric analysis and thermodynamic modelling of Portland cement-based mortars exposed to sodium chloride solution
(Journal article; Peer reviewed, 2017)Thermogravimetric analysis (TGA), powder X-ray diffraction (XRD) and thermodynamic modelling have been used to obtain Friedel's salt profiles for saturated mortar cylinders exposed to a 2.8 M NaCl solution. Comparison of ... -
Friedman Score in Relation to Compliance and Treatment Response in Nonsevere Obstructive Sleep Apnea
(Peer reviewed; Journal article, 2020)Nonsevere obstructive sleep apnea (OSA) is most often treated with a continuous positive airway pressure (CPAP) device or a mandibular advancement splint (MAS). However, patient compliance with these treatments is difficult ... -
Friend and foe? Self-deception in organisations
