A Biomarker Study of the Marine Recipient of Alcoa Lista using Littorina littorea as Sentinel Species
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)The waste water effluent from the Søderberg aluminium production plant Alcoa Lista is discharged into the marine recipient Husebybukta. The discharge contains several compounds that can have toxic effects on the living ... -
A new design of a cost effective membrane desalination plant powered by a wind turbine
(Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013)Wind is a plentiful source of energy. Wind turbines used to generate electricity come in a variety of sizes. Large wind turbines, which are usually installed in clusters are called wind farms, and can generate large amounts ... -
A new species of Pollenia Robineau-Desvoidy, 1830 from Jordan (Diptera: Calliphoridae: Polleniinae)
(Journal article; Peer reviewed, 2016-01)A new species, Pollenia bartaki sp. nov., assigned to the Pollenia rudis species-group in Pollenia Robineau-Desvoidy, 1830, is described on the basis of a single male specimen captured in Jordan. Its strongly curved surstylus ... -
A proteomic study for serum biomarkers for variations of two genotypes of Anaplasma phagocytophilum in infected lambs
(Masteroppgave/UIS-TN-IMN/2008;, Master thesis, 2008-12)The work in this thesis was Collaboration between the Norwegian School of Veterinary Science (NSVS), IRIS (the International Research Institute of Stavanger), and the University of Stavanger. NSVS innoculated two genotypes ... -
A spacetime not characterized by its invariants is of aligned type II
(Journal article; Peer reviewed, 2011)By using invariant theory we show that a (higher-dimensional) Lorentzian metric that is not characterised by its invariants must be of aligned type II; i.e., there exists a frame such that all the curvature tensors ... -
A study of the effect of pumps and desanding cyclones on oil droplets in produced water
(Masteroppgave/UIS-TN-IMN/2009;, Master thesis, 2011)The production of petroleum resources includes co-producing water. This water contains oil products and needs to be treated before discharge to sea or re-injection into the reservoir. The amount of produced water increases ... -
Adsorption of the phytoestrogens, genistein and daidzein, onto the iro oxide-hydroxide goethite
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Genistein and daidzein are plant-derived compounds called phytoestrogens, and they are found in high concentrations in legumes, primarily soy. Phytoestrogens function as endocrine disrupting chemicals (EDCs) in animals ... -
Aerobic biological treatment of produced water from oil production
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Produced water is the largest waste stream generated from the oil and gas industry. Water of varying quantities is always produced along with oil and has to be separated from the oil. The amount of produced water generated ... -
All metrics have curvature tensors characterised by its invariants as a limit: the ϵ-property
(Journal article; Peer reviewed, 2011)We prove a generalisation of the ϵ-property, namely that for any dimension and signature, a metric which is not characterised by its polynomial scalar curvature invariants, there is a frame such that the components of the ... -
Alpha-Synuclein and synuceinopathies as related to Parkinson's disease
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)Parkinson’s disease (PD) is a chronic, progressive, complex, age-related and movement neurodegenerative disorder, caused by the loss of dopaminergic neurons in a small portion of cells within the mid brain known as the ... -
Alvamaja chlorometallica gen. n., sp. n. from Europe : the first metallic Rhinophoridae (Diptera)
(Journal article; Peer reviewed, 2010)Alvamaja chlorometallica gen. n., sp. n. is described from the southern part of Serbia. It has a perplexing combination of characters for an oestroid fly: green metallic body colour with silvery pollinosity; absence of ... -
An analysis of asset availability performance: a practical determination of well system reliability and maintainability.
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-15)With decreasing oil prices, optimizing existing production is essential to generate as much revenue as possible. When the product sold decreases in value, more volume is required to maintain the revenue levels. Therefore, ... -
An investigation of permeability and porosity evolution of Kansas chalk under in-situ conditions
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013)Injections of brine into the chalk can leads to compaction. The chemical impacts of water injection on the mechanical strength of chalk have been investigating for several years. Also, porosity and permeability evolution ... -
