Behavior of Al4C3 Particles During Flotation and Sedimentation in Aluminum Melts
(Peer reviewed; Journal article, 2021)Al4C3 particles form during the primary production of aluminum via molten salt electrolysis due to the carbon solubility and direct contact between bath, metal, and carbon anodes. Additional Al4C3 may form during melt ... -
Behavior of Slag in Ferromanganese and Silicomanganese Smelting Process
(Peer reviewed; Journal article, 2021)A review of studies by Safarian et al. and Kim show that the smelting reaction at equilibrium for ferromanganese and silicomanganese alloys is defined by the coupled reaction in the carbon-saturated condition 2Mn––––+(Si ... -
Behavioral buffering of extreme weather events in a high-Arctic herbivore
(Journal article; Peer reviewed, 2016)As global warming advances, there is a growing concern about the impact of extreme weather events on ecosystems. In the Arctic, more frequent unseasonal warm spells and rain-on- snow events in winter cause changes in ... -
Behaviour of Aluminium Carbide in Al-melts during Re-melting
(Journal article; Peer reviewed, 2019)The presence of non-metallic inclusions in aluminium has become a more critical issue with increasing demands on surface quality and low final wall thicknesses of products. Aluminium carbide particles form during the primary ... -
Behaviour of iron and titanium species in cryolite-alumina melts
(Dr.ingeniøravhandling, 0809-103X; 2000:118, Doctoral thesis, 2000)The solubility of divalent iron oxide in cryolite-based melts was studied. Both electrochemical and chemical techniques were employed. To ensure that only divalent iron was present in solution, the melt was contained in ... -
Behaviour of nickel coatings made by brush plating technology in conditions of cavitation erosion and corrosion
(Peer reviewed; Journal article, 2023)The basic hypothesis of the research was that the structure of the coating, i.e. the type of defects, affects the mechanical and electrochemical properties, as well as the resistance to cavitation erosion and corrosion. ... -
Behaviour of nickel, iron and copper by application of inert anodes in aluminium production
(Dr. ingeniøravhandling, 0809-103X; 2000:104, Doctoral thesis, 2000)A thorough investigation was performed on the behaviour of Ni, Fe and Cu oxides dissolved in cryolite melts, and the solubility of these species was measured as a function of alumina content, NaF/AlF3 molar ratio (CR) and ... -
Behaviour of the S1 and S2 Components of the Semidiurnal Tide in the MLT
(Master thesis, 2016)9 years (2000-2008) of wind data from a longitudinal chain of up to 10 Super Dual Auroral Radar Network (SuperDARN) radars spanning over 184 degrees in longitude and ranging in latitude from 51.4 - 65.7 degrees N is used ... -
Behaviour of the slip-cast crucible as a contamination source during silicon directional solidification
(Master thesis, 2016)In this work the behaviour of the slip-cast crucible as a contamination source of multicrystalline silicon during directional solidification (DS) was investigated. Transport parameters of iron were estimated in two types ... -
Behavioural and demographic changes in impala (Aepyceros melampus) populations after a decade of changed conservation management – a case study in the Serengeti Ecosystem, Tanzania
(Master thesis, 2019)I det vestlige Serengeti-økosystemet er det gjort betydelige investeringer i bevaring og forvaltning av Grumeti-området siden begynnelsen av det 21. århundre. Ved å bruke impala (Aepyceros melampus) som studieart, undersøkte ... -
Behavioural and demographic changes in impala populations after 15 years of improved conservation management
(Peer reviewed; Journal article, 2021)Many protected areas (PAs) have been created globally in response to the dramatic human- induced decline in biodiversity. However, not all PAs successfully preserve their biodiversity and continued monitoring is vital to ... -
Behavioural Ecology of Free-ranging and Reintroduced African Wild Dog (Lycaon pictus) Packs in the Serengeti Ecosystem, Tanzania
(Doctoral theses at NTNU;2017:154, Doctoral thesis, 2017)Worldwide, large carnivore conservation has become an increasing challenge in the face of human population growth and anthropogenic development adjacent to protected areas. African wild dogs (Lycaon pictus) range widely ... -
Behavioural effects on environmental pollution in threespine stickleback Gasterosteus aculeatus L
(Doctoral thesis, 2003)The aims of this study were to investigate the effects of known environmental contaminants on defined behavioural variables in fish, and to discuss properties of these behavioural traits that make them useful as potential ... -
Behavioural traits correlate in zebrafish (Danio rerio) selected for high and low upper thermal tolerance
(Master thesis, 2019)Ferskvannssystemer er spesielt sårbare for klimaforandringer, så forskning på ferskvannsorganismer i lys av temperaturforandringer er viktig. I denne studien, ble sebrafisk selektert gjennom fire generasjoner for øvre ... -
Being stressed outside the park — conservation of African elephants (Loxodonta africana) in Namibia
(Journal article; Peer reviewed, 2017)The conservation of the African savanna elephant (Loxodonta africana) is of prime importance for many African countries. Interactions between elephants and humans are known to induce stress and thereby have the potential ... -
