Impact of the number of previous lumbar operations on patient-reported outcomes after surgery for lumbar spinal stenosis or lumbar disc herniation
(Peer reviewed; Journal article, 2023)Aims Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. Methods This ... -
Impact of the Pacific sector sea ice loss on the sudden stratospheric warming characteristics
(Peer reviewed; Journal article, 2022)The atmospheric response to Arctic sea ice loss remains a subject of much debate. Most studies have focused on the sea ice retreat in the Barents-Kara Seas and its troposphere-stratosphere influence. Here, we investigate ... -
Impact of the Rotavirus Vaccination Program in Norway After Four Years With High Coverage
(Peer reviewed; Journal article, 2020)Background: Use of rotavirus vaccines worldwide since 2006 has led to a significant impact on the burden of rotavirus disease. However, only a third of European countries have introduced rotavirus vaccination in their ... -
The impact of the Russia-Ukraine crisis on the stock market: Evidence from Australia
(Journal article; Peer reviewed, 2023)This paper investigates the effect of the Russia–Ukraine crisis on the Australian stock market. Using the event study methodology, we find significantly negative abnormal returns on the event date (i.e., the first trading ... -
Impact of the Russian Invasion on Mental Health of Adolescents in Ukraine
(Peer reviewed; Journal article, 2022)Objective Very limited evidence is available on the psychological impact of war on adolescents in Ukraine. This study compared war experiences and posttraumatic stress disorder (PTSD), anxiety and depression in adolescents ... -
Impact of the stock market, major currencies, precious metals and central banks on the volatility of Bitcoin
(Master thesis, 2019)Volatilitet er en av de viktigste risikokarakteristikkene til en finansiell aktiva. Nylig har interessen for Bitcoin økt, men til tross for Bitcoins høye volatilitet er forskning på dette feltet begrenset. Vi studerer ... -

Impact of the Temporal Distribution of Faults on Prediction of Voltage Anomalies in the Power Grid
(Chapter, 2020)Is it possible to reliably predict voltage anomalies in the power grid minutes in advance using machine learning models trained on large quantities of historical data collected by power quality analysers (PQA)? Very little ... -
Impact of thermal history on defects formation in the last solid fraction of Cz silicon ingots
(Journal article; Peer reviewed, 2018)For the first time, the impact of the tail detachment on the quality of the last solid fraction of a Czochralski silicon ingot body is reported. Simulations of the thermal history were performed on CGSim software and showed ... -
The Impact of Thermal History on Water Adsorption in a Synthetic Nanolayered Silicate with Intercalated Li+ or Na+
(Peer reviewed; Journal article, 2020)For applications benefitting from the swelling properties of nanolayered silicates (clay minerals), it is of paramount importance to understand the hysteresis in the clay–water interaction. In this context, the present ... -
The impact of thermal seasonality on terrestrial endotherm food web dynamics: a revision of the Exploitation Ecosystem Hypothesis
(Peer reviewed; Journal article, 2020)Many terrestrial endotherm food webs constitute three trophic level cascades. Others have two trophic level dynamics (food limited herbivores; plants adapted to tackle intense herbivory) or one trophic level dynamic ... -
The impact of thermo-mechanical processing routes on product quality in integrated aluminium tube bending process
(Peer reviewed; Journal article, 2021)This study was conducted to provide a better understanding of the role of electric field strength in the production of aftereffects in resting state scalp electroencephalography by repetitive transcranial magnetic stimulation ... -
Impact of thyrotropin receptor antibody levels on fetal development in two successive pregnancies in a woman with Graves' Disease
(Peer reviewed; Journal article, 2013)Background: Treatment with radioiodine for Graves’ disease regularly increases the level of antithyroid antibodies, and transplacental passage of stimulating thyrotropin receptor antibodies (TRAb) may cause fetal ... -
Impact of time varying angular frequency on the separation of instantaneous power components in stand-alone power systems
(Book, 2017)The paper addresses the impact that time varying angular frequencies observed in electrical signals can have on the calculation and separation of components from the instantaneous electric power signal. Instantaneous power ... -
Impact of TiO2 nanoparticles on freshwater bacteria from three Swedish lakes
(Journal article; Peer reviewed, 2015)Due to the rapidly rising production and usage of nano-enabled products, aquatic environments are increasingly exposed to engineered nanoparticles (ENPs), causing concerns about their potential negative effects. In this ... -
