    • Improving the Decision-making of Reverse Logistics Network Design Part I: A MILP Model under Stochastic Environment 

      Yu, Hao; Solvang, Wei Deng (Peer reviewed; Bokkapittel; Book; Bok; Chapter, 2018-02-11)
      The study of the network design problems related to reverse supply chain and reverse logistics is of great interest for both academicians and practitioners due to its important role for a sustainable society. However, reverse logistics network design is a complex decision-making problem that involves several interactive factors and faces many uncertainties. Thus, in order to improve the reverse ...
    • Solution of Pure Scattering Radiation Transport Equation (RTE) Using Finite Difference Method (FDM) 

      Khawaja, Hassan Abbas (Peer reviewed; Book; Bok; Bokkapittel; Chapter, 2017-05-19)
      Radiative transfer is the physical phenomenon of energy transfer in the form of electromagnetic radiation. The propagation of radiation through a medium is affected by absorption, emission, and scattering. Radiative Transfer Equation (RTE) have been applied in a many subjects including optics, astrophysics, atmospheric science, remote sensing, etc. Analytic solutions for RTE exist for simple cases, ...
    • Anti-Infective Effect of Adhesive Probiotic Lactobacillus in Fish is Correlated with Their Spatial Distribution in the Intestinal Tissue 

      He, Suxu; Ran, Chao; Qin, Chubin; Li, Shuning; Zhang, Hongling; de Vos, Willem M.; Ringø, Einar; Zhou, Zhigang (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-16)
      In this study, we tested the distribution of 49 Lactobacillus strains in the mucus and mucosa of the intestine tissue of zebrafish. We observed a progressive change in the spatial distribution of Lactobacillus strains, and suggested a division of the strains into three classes: mucus type (>70% in mucus), mucosa type (>70% in mucosa) and hybrid type (others). The hybrid type strains were more efficient ...

      Abraityte, Aurelija; Lunde, Ida Gjervold; Askevold, Erik Tandberg; Michelsen, Annika E.; Christensen, Geir Arve; Aukrust, Pål; Yndestad, Arne; Fiane, Arnt; Andreassen, Arne; Aakhus, Svend; Dahl, Christen Peder; Gullestad, Lars; Broch, Kaspar; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-14)
      The Wingless (Wnt) pathway has been implicated in the pathogenesis of dilated cardiomyopathy (DCM). To explore the role of Wnt modulators Wnt5a and sFRP3 in DCM patients we analyzed the expression of Wnt5a and sFRP3 in plasma and myocardium of DCM patients and evaluated their effects on NFAT luciferase activity in neonatal mouse cardiomyocytes. Elevated circulating Wnt5a (n = 102) was associated ...
    • Ficolins do not alter host immune responses to lipopolysaccharide-induced inflammation in vivo 

      Genster, Ninette; Østrup, Olga; Schjalm, Camilla; Mollnes, Tom Eirik; Cowland, Jack B.; Garred, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-20)
      Ficolins are a family of pattern recognition molecules that are capable of activating the lectin pathway of complement. A limited number of reports have demonstrated a protective role of ficolins in animal models of infection. In addition, an immune modulatory role of ficolins has been suggested. Yet, the contribution of ficolins to inflammatory disease processes remains elusive. To address this, ...
    • Thyristor based short circuit current injection in isolated grids 

      Hoff, Bjarte; Sharma, Pawan; Østrem, Trond (Peer reviewed; Bokkapittel; Chapter, 2017-02-16)
      This paper proposes a thyristor based short circuit current injector for providing short circuit current in isolated and weak grids, where sufficient fault current to trigger circuit breakers may not be available. This will allow the use of conventional miniature circuit breakers, which requires high fault current for instantaneous tripping. The method has been validated through experiments.

    • The alternative complement pathway is dysregulated in patients with chronic heart failure 

      Shahini, Negar; Michelsen, Annika E.; Nilsson, Per H.; Ekholt, Karin; Gullestad, Lars; Broch, Kaspar; Dahl, Christen P.; Aukrust, Pål; Ueland, Thor; Mollnes, Tom Eirik; Yndestad, Arne; Louwe, Mieke C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-14)
      The complement system, an important arm of the innate immune system, is activated in heart failure (HF). We hypothesized that HF patients are characterized by an imbalance of alternative amplification loop components; including properdin and complement factor D and the alternative pathway inhibitor factor H. These components and the activation product, terminal complement complex (TCC), were measured ...

      Everyone needs to be served, and a service network provides a set of services and/or help to please the people involved. No matter who is the service provider, government or retailer, there always been a clash between them and customers. Service providers are trying their best to serve customers as many as possible with a limitation of cost, while the satisfaction of customer might be neglected at ...

    • Re-politicisation as post-NPM response? Municipal companies in a Norwegian context 

      Moldenæs, Turid; Torsteinsen, Harald (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-17)
      This is an exploratory study of re-politicisation of municipal companies in one Norwegian municipality. Unlike re-municipalisation, which seems to imply the reversal of privatisation and out-contracting, and the reinstitution of municipal ownership, the Norwegian case demonstrates a continued adherence to the provision of certain public services through municipal companies. However, our study reveals ...
    • Association of occasional smoking with total mortality in the population-based Tromsø study, 2001-2015 

      Løchen, Maja-Lisa; Gram, Inger Torhild; Mannsverk, Jan T.; Mathiesen, Ellisiv B.; Njølstad, Inger; Schirmer, Henrik; Wilsgaard, Tom; Jacobsen, Bjarne K. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-28)

      Background: <br> Sufferers from bulimia nervosa (BN) and binge eating disorder (BED) underestimate the severity risk of their illness and, therefore, postpone seeking professional help for years. Moreover, less than one in five actually seek professional help and only 50% respond to current treatments, such as cognitive behavioral therapy (CBT). The impetus for the present trial is to explore a ...
