  1. 1. Hemodilution with dextran: Effects on blood flow and thrombus formation. An experimental study in the rabbit

    University dissertation from Department of Plastic and Reconstructive Surgery, Malmö University Hospital, Malmö, Sweden

    Author : Lieselotte Frost-Arner; Lund University.; Lunds universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; Hypertonic saline-dextran; Desmopressin; Heparin; Dextran; Rabbit; Synthetic vascular grafts; Blood flow; Hemodilution; Thrombus formation; Kirurgi; ortopedi; traumatologi; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : Microvascular surgery enables free tissue flaps to cover tissue defects, e.g. after trauma and malignancies. Although major improvements in techniques have been made, problems with poor tissue circulation and thrombus formation still exist. READ MORE

  2. 2. Effects of inflammatory mediators on human osteoblasts

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Frost; Uppsala universitet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; Orthopaedics; ortopedi;

    Abstract : Inflammatory mediators produced in or adjacent to bone have implications on bone and may induce both osteolysis and/or osteosclerosis. Inflammatory cytokines mediate these effects by acting either directly or indirectly on the bone cells. READ MORE

  3. 3. Laboratory Investigations of Frost Action Mechanisms in Soils

    University dissertation from Luleå : Luleå University of Technology

    Author : Deniz Dagli; Luleå tekniska universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold Regions Soil Mechanics; Frost Action; Frost Depth; Frost Heave; Heat Flow in Soils; Ice Lens Formation; Image Analysis; Laboratory Freezing Test; Soil Mechanics; Geoteknik;

    Abstract : Phase change of the water in the soil skeleton under cold climate conditions (also known as frost action in soils) affects soil properties and can be responsible for serious alterations in a soil body; causing damages (due to the volumetric expansion known as frost heave) to structures on or below the ground surface such as foundations, roads, railways, retaining walls and pipelines, etc. In order to improve the current design methods for roads against frost action, the Swedish Transport Administration (Trafikverket) has initiated a research program.

  4. 4. Condensation and frost formation in fibrous thermal-insulation materials

    University dissertation from Stockholm : US-AB

    Author : Tomáš Vrána; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; TECHNOLOGY Materials science Construction materials; TEKNIKVETENSKAP Teknisk materialvetenskap Konstruktionsmaterial;

    Abstract : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. READ MORE

  5. 5. Internal frost damage in concrete - experimental studies of destruction mechanisms

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Katja Fridh; Lund University.; Lunds universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tining; frysning; kallt klimat; frostskador skador; betong; materiallära; materialteknik; frost; ice formation; material technology; calorimetry; concrete; length change; upptining; fukt; beständighet; livslängd; forskning;

    Abstract : The aim of the study was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw.
