  2. 1. Chromosomal Instability and Genomic Amplification in Bone and Soft Tissue Tumours

    Author : David Gisselsson Nord; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear atypia; kinetochore; anaphase bridge; p53; breakage-fusion-bridge cycle; TP53; HMGIC; MDM2; mitotic instability; genomic instability; FISH; osteosarcoma; liposarcoma; amplification; tumour; chromosome; cytogenetics; Clinical genetics; Klinisk genetik;

    Abstract : Acquired genetic abnormalities are found in all types of malignant tumours and may contribute to neoplastic processes by altering protein structure or dosage. Many bone and soft tissue tumours (BSTT) are characterised by complex patterns of chromosome changes, including extensive intratumour heterogeneity and amplification of DNA sequences. READ MORE

  4. 2. Characterization of particulate matter from atmospheric fluidized bed biomass gasifiers

    Author : Eva Gustafsson; Michael Strand; Marcus Öhman; Linnéuniversitetet; []
    Keywords : biomass gasification; fluidized bed; particulate matter; particle morphology; particle elementary composition; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Through biomass gasification, biomass can be converted at high temperature to a product gas rich in carbon monoxide, hydrogen, and methane. After cleaning and upgrading, the product gas can be converted to biofuels such as hydrogen; methanol; dimethyl ether; and synthetic diesel, gasoline, and natural gas. READ MORE

  5. 3. Speciation of copper in ashes from municipal solid waste combustion

    Author : Henric Lassesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; copper compounds; MSWI ash; XANES; metal speciation; EXAFS; X-Ray absorption spectroscopy;

    Abstract : Copper is one of the most important trace elements in municipal solid waste (MSW) combustion. Knowledge of the speciation of copper is fundamental for the understanding of the effects of copper compounds on the combustion chemistry as well as of the environmental impact of the ash. READ MORE

  6. 4. Morbidity and mortality in patients with bundle branch block

    Author : Fariborz Tabrizi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : AV block; Bifascicular block; Congestive heart failure; Bundle branch block; Mortality; Myocardial infarction; Sudden cardiac death; Syncope.;

    Abstract : Background: Syncope is a predictor of subsequent high-degree atrioventricular (AV) block in patients with bifascicular block (BFB) but the time relationship between syncope and development of AV block has not been well-studied. Patients with BFB have a significantly higher mortality rate compared with an age and sex matched population. READ MORE

  7. 5. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels : Experimental and Modeling Approach

    Author : Farzad Moradian; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized-bed; combustion; gasification; waste-derived fuels; biomass; ash-related problems; deposit; fouling; slagging; bed agglomeration; thermodynamic equilibrium modeling;

    Abstract : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified. READ MORE
