  4. 2. Clinical characteristics and prognosis of peripartum cardiomyopathy

    Author : Kamilu Musa Karaye; Michael Henein; Krister Lindmark; Maria Schaufelberger; Umeå universitet; []
    Keywords : peripartum cardiomyopathy; characteristics; survival; selenium; RV dysfunction; Cardiology; kardiologi;

    Abstract : Background:Peripartum cardiomyopathy (PPCM) is an incompletely understood disease that causes significant morbidity and mortality in many parts of the world, including Northern Nigeria. The aims of this Thesis were: [1] to determine if selenium deficiency, serum ceruloplasmin and traditional birth practices are risk factors for PPCM, in Kano, Nigeria; [2] to describe the one year survival and left ventricular reverse remodeling (LVRR) in a group of patients with PPCM from three referral hospitals in Kano, Nigeria; [3] to identify potential electrocardiographic (ECG) predictors of PPCM; and [4] to assess right ventricular systolic dysfunction (RVSD) and remodelling in a cohort of PPCM patients in Kano, Nigeria.

  5. 3. Educational inclusion for students with neurodevelopmental conditions

    Author : Emma Leifler; Göteborgs universitet; Karolinska Institutet; Karolinska Institutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Educational inclusion; neurodevelopmental conditions; ADHD; autism; inclusive education;

    Abstract : Introduction: Inclusive education is the response to the human rights movement that requested equal rights to general education for all students, independent of their prerequisites and/or disabilities. Inclusion is different from integration, which concentrates on the capacities of an individual to adapt to a given mainstream. READ MORE

  6. 4. An Experimental Study of a Liquid Steel Sampling Process

    Author : Ola Ericsson; Andrey Karasev; Pär Jönsson; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; inclusion characteristics; sampling conditions; sample homogeneity.; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. READ MORE

  7. 5. The Effect of Ladle Treatment on Steel Cleanness in Tool Steels

    Author : Karin Steneholm; Pär Jönsson; Guozhu Ye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen activity; inclusion characteristics; vacuum degassing; desulphurization; slag; ladle; hydrogen; nitrogen; deslagging; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The aim of the present work was to get an overview of the steel cleanness in tool steel. Plant trial studies of three steel grades were done with different focuses.Firstly the change of the inclusion characteristics during the vacuum degassing in the ladle was looked upon. READ MORE
