Bioenergy potential of russia: Method of evaluating costs
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019)Paper proposes the method of evaluating costs for bioenergy supply in Russia based on energy analysis. The main deterrent factor is not as much limited resources as the marginal cost of production biofuels and the possibility of using cost-effective ways reducing greenhouse gas emissions, including capturing and carbon storage, alternative forms of renewable energy and energy efficiency and energy ... -
Preliminary Results on Waypoint Tracking for Spacecraft with Actuator Constraints
(Peer reviewed; Chapter; Bokkapittel, 2019-07-22)This paper presents preliminary results on how to perform waypoint tracking with spacecraft with actuator constraints. It considers a simplified spacecraft model and can be considered a deep space model, and shows how to perform waypoint tracking with only one main thruster together with full attitude control. As the spacecraft reaches close to the waypoint during a deceleration phase that makes the ... -

Person-centred, integrated and pro-active care for multi-morbid elderly with advanced care needs: A propensity score-matched controlled trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-03)<i>Background</i> - Person-centred care (PCC) focusing on personalised goals and care plans derived from “What matters to you?” has an impact on single disease outcomes, but studies on multi-morbid elderly are lacking. Furthermore, the combination of PCC, Integrated Care (IC) and Pro-active care are widely recognised as desirable for multi-morbid elderly, yet previous studies focus on single components ... -

Respirasjonsproblemer i de første tre leveår hos barn med fødselsvekt ≤ 2000 gram. En retrospektiv studie av barn innlagt nyfødt intensiv ved UNN Tromsø i perioden 01.01.04 til 31.12.13.
(Master thesis; Mastergradsoppgave, 2020-02-21)Bakgrunn: Premature barn fødes før lungeutviklingen er fullstendig og har ofte behov for respirasjonsstøtte i nyfødtperioden. Dette gir økt risiko for senere respirasjonsproblemer, herunder luftveisinfeksjoner og økt risiko for bronkial hyperreaktivitet som disponerer for astma. Metode: Retrospektiv studie av 540 journaler på barn med fødselsvekt ≤ 2000 gram og innlagt nyfødt intensiv ved ... -
Controlling a Chain of Integrators with Constrained Actuation Using Exponential Activation Functions
(Peer reviewed; Chapter; Bokkapittel, 2019-10-24)This paper shows how to control a chain of integrators with constrained actuation by using exponential activation functions. Specifically, it shows how the control law can be decomposed into several parts that can be activated as they are required, resulting in a simple control law that is able to make the states converge fast to zero. -
En empirisk tilnærming for vurdering av bevissthetsnivå basert på teoretiske betraktninger
(Master thesis; Mastergradsoppgave, 2020-02-21)I klinisk praksis det en stor utfordring at man mangler metoder for å vurdere bevissthetsnivå på en objektiv måte. I dag baseres den kliniske vurderingen av bevissthetsnivå på pasientens evne til, på en eller annen måte, å demonstrere sin egen subjektive opplevelse. Dette kan være villedende ettersom erfaring viser oss at ikke-responderende pasienter ikke er ensbetydende med ubevisste pasienter. ... -

This study used competing mortality risks analysis to evaluate the association between these factors and CRC survival.<p> <p><i>Methods</i> - A total of 96 889 cancer-free participants of the Norwegian Women and Cancer Study completed ... -
Adherence to the World Cancer Research Fund/American Institute for Cancer Research cancer prevention recommendations and risk of in situ breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-02)<i>Background</i> - Even though in situ breast cancer (BCIS) accounts for a large proportion of the breast cancers diagnosed, few studies have investigated potential risk factors for BCIS. Their results suggest that some established risk factors for invasive breast cancer have a similar impact on BCIS risk, but large population-based studies on lifestyle factors and BCIS risk are lacking. Thus, ... -

Checking the effectiveness of the point source model for describing the seasonal change ... -
Activity patterns in mammals: Circadian dominance challenged
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-15)The evidence that diel patterns of physiology and behaviour in mammals are governed by circadian ‘clocks’ is based almost entirely on studies of nocturnal rodents. The emergent circadian paradigm, however, neglects the roles of energy metabolism and alimentary function (feeding and digestion) as determinants of activity pattern. The temporal control of activity varies widely across taxa, and ungulates, ... -

Quality control of cervical cytology using a 3-type HPV mRNA test increases screening program sensitivity of cervical intraepithelial neoplasia grade 2+ in young Norwegian women-A cohort study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-05)Within 2021, Norway intends to complete implementation of HPV DNA-based primary screening for cervical cancer for women 34–69 years, while continue cytology-based screening for women 25–33 years. Over the recent years, the incidence of cervical cancer has increased by 30% among women younger than 40 years. In this subset of women, nearly 30% were diagnosed with a normal smear, as most recent smear, ... -
Self-reported traffic-related air pollution and respiratory symptoms among adults in an area with modest levels of traffic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-12)Health effects of traffic-related air pollution (TRAP) concentrations in densely populated areas are previously described. However, there is still a lack of knowledge of the health effects of moderate TRAP levels. The aim of the current study, a population-based survey including 16 099 adults (response rate 33%), was to assess the relationship between TRAP estimates and respiratory symptoms in an ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-11)Examination of Paradulichia-material collected from the Barents Sea during the Mareano cruises indicated that there are clear morphological differences between Paradulichia typica Boeck, 1871 from the Hardangerfjord, W. Norway and Paradulichia spinifera Gurjanova, 1946 from the Arctic. Based on our material and the original descriptions, these differences are the acute ventral parts of the body ... -

The Solovetsky historical and cultural complex was included in the list of UNESCO World Heritage Sites. Diesel fuel, which is used on the archipelago is expensive and pollutes the environment. By using Computational Fluid Dynamics (CFD) based numerical method, this study ... -
Seroprevalence of pestivirus in Eurasian tundra reindeer in Finland, Sweden, Norway, Iceland and Russian Federation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-29)Reindeer herding is of great importance for the indigenous people of the Fennoscandia peninsula and northern Russia. There are also free-ranging feral populations of reindeer in Finland, Iceland, Norway and Russian Federation. The genus Pestivirus contains several viral species that infect ungulates and often show capacity to transmit between different host species. Sera from 520 Eurasian tundra ...
