Design of iron(ii) spin-crossover compounds using de novo artificial evolution with fitness-function based on DommiMOE's implementation of LFMM
(Master thesis, 2015-06-01)This is a software development adding DommiMOE as a fitness-provider to the de novo artificial intelligence internally called Denoptim. The software supports stochastic conformational search, molecular dynamics, geometry ... -
Formation and Growth of Clusters of Sulfur Dioxide
(Peer reviewed; Journal article, 2015-06-01)Formation and growth of neutral SO2 clusters is investigated in an adiabatic-expansion setup by means of sulfur 2p (S2p) photoelectron spectroscopy and theoretical modeling. The shift in S2p ionization energy between the ... -
Kartlegging av katalysatorer og enkle studier av reaksjonsmekanismen i LtL-prosessen
(Master thesis, 2015-06-15)Det forskes mye på å utnytte lignocellulosisk biomasse som råmateriale for produksjon av energi, kjemikalier og materialer. Dette kan bidra til å begrense bruken av fossilt petroleum og dermed imøtekomme kravene om å legge ... -
Fishmeal physicochemical properties. Impact on the fish feed extrusion process, phase transitions and physical pellet quality
(Doctoral thesis, 2015-06-19)Norway is the world largest producer of Atlantic salmon (Salmo salar). In 2013 the Norwegian aquaculture industry produced 1.2 million metric tons salmon with the use of 1.5 million metric tons of commercial feeds. The ... -
Active Smarter Kids (ASK): Rationale and design of a cluster-randomized controlled trial investigating the effects of daily physical activity on children's academic performance and risk factors for non-communicable diseases
(Peer reviewed; Journal article, 2015-07-28)Background Evidence is emerging from school-based studies that physical activity might favorably affect children’s academic performance. However, there is a need for high-quality studies to support this. Therefore, the ... -
4-Alkylated Silver–N-Heterocyclic Carbene (NHC) Complexes with Cytotoxic Effects in Leukemia Cells
(Peer reviewed; Journal article, 2015-08-06)Computational chemistry has shown that backbone-alkylated imidazoles ought to be efficient ligands for transition metal catalysts with improved carbene-to-metal donation. In this work, such alkylated imidazoles were ... -
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 ... -
