      Faecal pellet production and content along with egg production of the dominant copepod species Acartia clausi were studied in the Thermaikos Gulf (NW Aegean Sea) during a prebloom and a bloom of the toxic dinoflagellate Dinophysis acuminata. Both faecal pellet production (6.8–8.6 ind<sup>−1</sup> d <sup>−1</sup> ) and egg production (15.8–47.6 ind<sup>−1</sup> d <sup>−1</sup> ) appeared unrelated ...
    • Er kjærlighet en forutsetning for rettferdighet? 

      Fjørtoft, Kjersti (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-12)
      Martha Nussbaum mener at forsvarere av samtidige liberale rettferdighetsteorier ikke har tatt innover seg det hun kaller anstendige samfunns moralpsykologi. Alle samfunn trenger emosjonell støtte, dette gjelder også liberale rettferdige samfunn. Liberale og rettferdige institusjoner som ivaretar menneskets verdighet, frihet, toleranse og respekt forutsetter at borgerne føler kjærlighet til disse ...
    • Environment Constrains Fitness Advantages of Division of Labor in Microbial Consortia Engineered for Metabolite Push or Pull Interactions 

      Beck, Ashley E.; Pintar, Kathryn; Schepens, Diana; Schrammeck, Ashley; Johnson, Timothy; Bleem, Alissa; Du, Martin; Harcombe, William R.; Bernstein, Hans Christopher; Heys, Jeffrey J.; Gedeon, Tomas; Carlson, Ross P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-28)
      Fitness benefits from division of labor are well documented in microbial consortia, but the dependency of the benefits on environmental context is poorly understood. Two synthetic Escherichia coli consortia were built to test the relationships between exchanged organic acid, local environment, and opportunity costs of different metabolic strategies. Opportunity costs quantify benefits not realized ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-25)
      BACKGROUND: The major risk factors for atherosclerotic cardiovascular disease differ by race or ethnicity but have largely been defined using populations of European ancestry. Despite the rising prevalence of cardiovascular disease in Africa there are few related data from African populations. Therefore, we compared the association of established cardiovascular risk factors with carotid-intima ...
    • Family care strategies in an unpredictable ICU environment. ICU nurses’ and physicians’ interprofessional and individual strategies for critically ill ICU patients’ families – a qualitative study 

      Nygaard, Anne Mette (Doctoral thesis; Doktorgradsavhandling, 2022-12-13)
      <p><i>Background:</i> Critical illness not only disrupts the patient’s life, but also the lives of close family members. The care provided by ICU nurses and physicians can reduce the family members’ burden and improve the patient's outcome. Previous research shows that although ICU families generally report high satisfaction, there are several barriers to family care and areas for improvement. Family ...
