  1. 1. Single fluid inclusion analysis using ToF-SIMS Implications for ancient Earth biodiversiy and paleoenvironment studies

    University dissertation from Stockholm : Department of Geological Sciences, Stockholm University

    Author : Sandra Siljeström; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ToF-SIMS; time-of-flight secondary ion mass spectrometry; fluid inclusions; biomarkers; hopanes; steranes; early life; paleoenvironment; oil; eukaryotes; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Geochemistry; geokemi;

    Abstract : When and how life first emerged on the Earth is an area of intense research. Signs of the first life on Earth, including morphological fossils, are scarce and hard to interpret. An alternative approach is to study organic biomarkers, which are molecular fossils commonly considered as bona fide biosignatures. READ MORE

  2. 2. Simulation of deformable objects transported in fluid flow

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Arash Alizad Banaei; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : Deformable particles suspended in a viscous fluid can be found in many industrial and biological applications. In this thesis, two different numerical tools have been developed to simulate suspensions of capsules, thin membranes enclosing a second fluid and a rigid nucleus so to work as model for ”Eukaryotic” cells, and flexible slender bodies known as filaments/fibres.

  3. 3. Modeling nanofiber transport and deposition in human airways

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sofie Högberg; Luleå tekniska universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : An understanding of the complex motion of fibrous particles is important in a wide range of areas, including inhalation toxicology, targeted drug delivery, composites manufacturing, paper making, and food processing. While the applications are diverse, the governing equations for the fiber motion may be shared. READ MORE

  4. 4. Permeability modelling and particle deposition mechanisms related to advanced composites manufacturing

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Markus Nordlund; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Advanced composite materials reinforced by Non-Crimp Fabrics (NCFs) are becoming increasingly popular for high performance, light weight, complex structures, due to their high mechanical properties and relatively cheap production costs. These materials, not only improve the structural properties, but also induce great possibilities for reduced fuel consumptions for aircrafts and automotives, due to their high strength to weight ratio.

  5. 5. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold

    University dissertation from Stockholm : Materialvetenskap

    Author : Robert Eriksson; KTH.; [2003]
    Keywords : up-hitt teeming; model powder; inclusions; plant trials; thermal diffusivity; fluid flow; physical modeling;

    Abstract : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. READ MORE
