  1. 16. Microstructure Evolution and Mechanical Properties of Haynes 282

    Författare :Ceena Joseph; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

    Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER

  3. 17. Modern Artificial Recharge Plants : Combining chemical flocculation with aquifer recharge

    Författare :Kristofer Hägg; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Natural organic matter NOM ; Chemical flocculation; Ultrafiltration membrane; Disc filtration; Managed Aquifer Recharge;

    Sammanfattning : Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. LÄS MER

  4. 18. Start-up and operational strategies for deammonification plants : - a study with one-stage moving bed biofilm reactors treating reject water

    Författare :Linda Kanders; Eva Thorin; Susanne Lackner; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : To limit eutrophication, wastewater treatment plants use biological methods to convert degraded nitrogen to nitrogen gas. Deammonification, or partial nitritation in combination with anammox, has been shown to be an energy efficient process. LÄS MER

  5. 19. Microbial Ecology of Granular Sludge

    Författare :Raquel Liebana; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-throughput DNA analysis; sequencing batch reactors; granular structure; wash-out dynamics; aerobic granular sludge; disturbance; fluorescence in-situ hybridization; microbial community dynamics; granulation; reproducibility;

    Sammanfattning : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. LÄS MER

  7. 20. Early diagnosis, treatment, and Health-Related Quality of Life in women with mild Breast Cancer-Related Lymphedema

    Författare :Katarina Blom; Rehabilitering och hållbar hälsa; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lymphedema; breast cancer; compression garment; Diagnosis; treatment; health-related quality of life;

    Sammanfattning : Background: Early diagnosis and treatment of Breast Cancer-RelatedLymphedema (BCRL) are important to prevent lymphedema progress and impacton Health-Related Quality of Life (HRQOL). The treatment includes self-care andtreatment with compression garment. In mild BCRL, the lymphedema can be local, without an increase in arm volume. LÄS MER
