Breeding success of the Gyrfalcon (Falco rusticolus) in northern Norway in relation to food supply and weather
(Master thesis, 2012)Food supply and weather are among the main factors limiting bird numbers. In raptors prey availability may be closely linked to the reproduction output while weather conditions most often act indirectly by modifying food ... -
Bridging scales with thermodynamics: From nano to macro
(Journal article; Peer reviewed, 2014)We have recently developed a method to calculate thermodynamic properties of macroscopic systems by extrapolating properties of systems of molecular dimensions. Appropriate scaling laws for small systems were derived using ... -
Bright, noniridescent structural coloration from clay mineral nanosheet suspensions
(Journal article; Peer reviewed, 2022) -
Bringing together materials and business ontologies for protective coatings
(Chapter, 2022)This work discusses how to connect business decision support systems, implemented in terms of the BPMN and DMN standards, with materials modelling workflows. The suggested approach facilitates interoperability of materials ... -
Briquetting of Manganese Oxide Fines with Organic Binders - How well suited are organic binders for agglomeration of Mn-oxide fines?
(Master thesis, 2017)Dust and fines are created throughout the ferromanganese metal production. These fines are collected from ventilation filters, screening operations and off-gas cleaning facilities. As the fines contain a substantial amount ... -
Brittle and Ductile Fracture of X80 Arctic Steel
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:258, Doctoral thesis, 2012)This PhD work has focused on the effect of microstructure and changes in microstructure introduced by welding procedure, on the brittle to ductile transition properties of high strength low alloy steels which have been ... -
Brittle to Quasi-Brittle Transitions in the Soft Clamp Fiber Bundle Model
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:307, Doctoral thesis, 2013)In this thesis I describe a soft clamped quasi static fiber bundle model for two dimensional interfacial fracture. The soft clamps distribute the stress amongst the fibers through elastic forces. The model display three ... -
Broad-band GVD Measurement of Specialty Fibers in mid-IR
(Chapter, 2012)We demonstrate a novel interferometeric setup for broad-band (>300nm) GVD measurements in short-length optical fibers in the mid-IR wavelength range using a superluminescent fiber source and investigate specialty fibers ... -
Broad-scale distribution of the winter protozooplankton community in the North Sea.
(Journal article; Peer reviewed, 2018)Protozooplankton (PZP) (here size range: 12–200 μm) are rarely sampled over a broad scale, especially in ecosystem monitoring programs, despite their trophodynamic importance as grazers in the microbial loop and as prey ... -
Broadband Dispersion Measurement of ZBLAN, Germanate and Silica Fibers in MidIR
(Journal article, 2012)We report the first ultra-broad band dispersion measurements in short-length ZBLAN, germanate and silica-based optical fibers in the near- and midIR wavelength ranges between 1.7 and 2.0 μm and from 2.3 to 2.45 μm, using ... -
Broadband infrared and THz transmitting silicon core optical fiber
(Peer reviewed; Journal article, 2020)Silicon waveguide structures are a viable alternative for the transmission of signals over a wide range of frequencies, and new fabrication methods are key to increased applications. In this work, THz transparency of ... -
Broadband method for group velocity dispersion measurements in the mid-infrared
(Journal article; Peer reviewed, 2011)A setup for broadband measurements of dispersion parameter in optical fibers based on the Mach–Zehnder interferometer is developed. Tm-doped fiber pumped at 1.61 μm was used as a source of broadband emission, that allowed ... -
Broadly tunable high-power continuous-wave Cr2+:CdS laser
(Chapter, 2011)We report spectroscopic and laser study of Cr2+:CdS laser - an attractive material for 3 µm room-temperature operation. 1.8 W of output power, continuously tunable over 1000 nm from 2240 nm to 3285 nm was demonstrated. -
Bromination and Suzuki reaction towards purine-based CSF-1R inhibitors
(Master thesis, 2017)The aim of this master thesis was to develop a suitable synthetic procedure towards 6-amino-8-arylpurines as potential CSF-1R inhibitors. The chosen three-step route entailed thermal amination of 6-chloropurine with various ... -
Brood Parasitism in Asian Cuckoos: Different Aspects of Interactions between Cuckoos and their Hosts in Bangladesh
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:198, Doctoral thesis, 2011)The interaction between brood parasitic cuckoos and their hosts represents a traditional example of coevolution, whereby obligate interspecific brood parasitic cuckoos completely rely on their hosts to do their parental ... -
Brood parasitism on Meadow Pipits Anthus pratensis by Common Cuckoos Cuculus canorus in two mountain areas in Norway
(Journal article; Peer reviewed, 2019)In the period 2001–2014 we studied Common Cuckoo Cuculus canorus brood parasitism on Meadow Pipits Anthus pratensis in two mountain areas; one located in the eastern and one in the western part of southern Norway. In the ... -
