(Peer reviewed; Journal article, 2016-10)Objective. To investigate the effect of a seven-month, school-based cluster-randomized controlled trial on academic performance in 10-year-old children. Methods. In total, 1129 fifth-grade children from 57 elementary schools ... -
Effects of Strain and Kinetics on the H2O2‑Assisted Reconstruction of Ag−Au−Ag Nanorods
(Journal article; Peer reviewed, 2020)Morphology of Ag nanocrystals (NCs) is essential to the NC application in catalysis, optics, and as antibacterial agents. Therefore, it is important to develop synthetic methods and understand the evaluation of NC morphology ... -
Effekten av ulike ekstraksjonsmetoder for syreforbindelser i råolje med hensyn på syresammensetning og fysikalske egenskaper
(Master thesis, 2008-06-02)Råolje er en kompleks blanding som består av et mangfold av komponenter og forbindelser. Det er vanskelig å identifisere enkeltforbindelser i en råolje, og for å bedre kunne studere de ulike forbindelsestypene blir oljen ... -
The efficiency of maltodextrin and porous silicon nanoparticles for the in vitro and in vivo stabilization of tyrosine hydroxylase
(Master thesis, 2016-06-01)Parkinson's disease is a severe neurodegenerative disease, which causes deterioration of the dopaminergic neurons of the substantia nigra. Lack of dopamine causes motor function problems and cognitive decline. Due to ... -
Electronic properties of chlorine, methyl, and chloromethyl as substituents to the ethylene group-viewed from the core of carbon
(Peer reviewed; Journal article, 2015-08-17)“Substituent effects” is an important and useful concept in organic chemistry. Although there are many approaches to parametrizing the electronic and steric effects of substituents, the physical basis for the parameters ... -
Emulsion and Surface-Active Properties of Fish Solubles Based on Direct Extraction and after Hydrolysis of Atlantic Cod and Atlantic Salmon Backbones
(Journal article; Peer reviewed, 2021)The focus on natural foods and “clean” labeled products is increasing and encourages development of new biobased ingredients. Fish solubles derived from downstream processing of side stream materials in the fish filleting ... -
Enhanced Oil Recovery by Combined Low Salinity Water and Polymer Flooding
(Doctoral thesis, 2014-06-19)World energy demand is continuously increasing as the developed and developing countries consume more energy to keep their growing industries running. Significant portion of the energy demand is supplied by fossil energies, ... -
Environmental Remediation: Removal of polycyclic aromatic hydrocarbons Dissertation
(Doctoral thesis, 2012-08-17)Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous persistent semi-volatile organic compounds. They are contaminants that are resistant to degradation and can remain in the environment for long periods due to their ... -
