  1. 1. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective

    Författare :Claudia Coll Mora; Anna Sobek; Matthew MacLeod; Emma J. Rosi; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organic micropollutants; biodegradation; persistence; rivers; flume mesocosms; Junge relationships; OECD 308 bottle incubations; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. LÄS MER

  3. 3. Francisella tularensis: persistence, dissemination and source attribution : a theoretical and computational approach

    Författare :Chinmay Kumar Dwibedi; Anders Johansson; Pär Larsson; Markus Antwerpen; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella; genomics; evolution; microbial forensics; dispersal; persistence; mikrobiologi; Microbiology;

    Sammanfattning : The bacterium Francisella tularensis causing tularemia in humans and other mammals displays little genetic diversity among genomes across temporal and spatial scales. F. tularensis infects humans with an extremely low infectious dose and causes natural seasonal tularemia outbreaks. LÄS MER

  5. 5. Objects in Time : Studies of Persistence in B-time

    Författare :Tobias Hansson Wahlberg; Teoretisk filosofi; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; B-time; three-dimensionalism.; stage theory; tenselessness; persistence; perdurance; mereology; four-dimensionalism; dispositions; endurance; B-theory of time; change; temporary intrinsics;

    Sammanfattning : This thesis is about the conceptualization of persistence of physical, middle-sized objects within the theoretical framework of the revisionary ‘B-theory’ of time. According to the B-theory, time does not flow, but is an extended and inherently directed fourth dimension along which the history of the universe is ‘laid out’ once and for all. LÄS MER
