  2. 1. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag

    Author : Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. READ MORE

  4. 2. Slag Cleaning of a Reduced Iron Silicate Slag by Settling : Influence of Process Parameters and Slag Modification on Copper Content

    Author : Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Pekka Taskinen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Copper losses; matte; speiss; fayalite slag; temperature; settling time; solid phases; industrial trial; CaO modification; Process Metallurgy; Processmetallurgi;

    Abstract : During the pyrometallurgical extraction of copper, a significant part of the copper is lost with discard slag, which decreases profits, overall copper recovery, and efficiency of raw material usage. Smelting furnace slag usually has a copper content that is close to or higher than that of copper ores. READ MORE

  5. 3. On Crack Dynamics in Brittle Heterogeneous Materials

    Author : Jenny Carlsson; Per Isaksson; Urban Wiklund; Cecilia Persson; Ralf Denzer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Abstract : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. READ MORE

  6. 4. ADHD in adolescence : Evaluation of a structured skills training group and associated predictors of functional impairment

    Author : Jenny Meyer; Johan Isaksson; Mia Ramklint; Peik Gustafsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; Adolescents; CBT; DBT; Group treatment; Functional impairment; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Abstract : Attention-deficit/hyperactivity disorder (ADHD) is related to difficulties with self-control and functional impairment across several life domains. Cognitive behavioral therapy has been recommended for adolescents with ADHD, but evidence of its effectiveness remains scarce. READ MORE

  7. 5. Life situation of next of kin to persons in need of care-cronic sorrow, burden, quality of life

    Author : Elisabeth Liedström; Annica Kihlgren; Kirsti Skovdahl; Ann-Kristin Isaksson; Jenny Windahl; Anna Kristensson Ekwall; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; life situation; next of kin; informal caregiving; chronic sorrow; burden; quality of life; Partnership model; Vårdvetenskap; Nursing Science;

    Abstract : Nursing research has been performed during the last 20-30 years, about the next of kin’s vulnerability. Despite this, the health care system has had difficulties to integrate the next of kin in a way that gives support. READ MORE
