  1. 1. Chloride profiling in marine concrete - methods and tools for sampling

    Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; klorider; betong; provtagning; concrete; sampling; chloride;

    Sammanfattning : This project focuses on how to determine the chloride content in concrete structures exposed to marine environment in an accurate way. When analyzing dust from dry drilling in concrete, it is very often a fact that the chloride profiles show extensive variations even if the sampling has been performed within a very concentrated area with the sampling points close to each other.

  3. 2. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates

    Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloride ingress; sampling methods; corrosion rates; sheet piling; ultra-sonic measurements; service life; durability; quay structures; harbor structures;

    Sammanfattning : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. LÄS MER

  4. 3. Rättskraft och korrektiv : En förvaltningsrättslig studie

    Författare :Gustaf Wall; Lena Marcusson; Ingrid Helmius; Henrik Wenander; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Rättskraft; korrektiv; förvaltningsrätt; förvaltningsprocessrätt; gynnande beslut; trygghet; omprövning; rättelse; tvåpartsprocess; europeisering; Administrative Law; Förvaltningsrätt;

    Sammanfattning : In Swedish administrative law, there are numerous opportunities for authorities and others who fulfill public tasks to correct decisions. As an important limitation of this power, there are general principles on the immovability of administrative decisions. As a general rule, a favorable decision may not be corrected. LÄS MER

  5. 4. Exploring glycoside hydrolase family 5 (GH5) enzymes

    Författare :Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []

    Sammanfattning : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. LÄS MER

  7. 5. Evaluating an experimental model consecutive to abdominal wall hernia repair outcome

    Författare :Annika Winsnes; Karin Strigård; Ulf Gunnarsson; Peter Falk; Birgit Stark; Henrik Thorlacius; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hernia; mesh; luciferase; full thickness skin grafts; mice; IPOM; onlay; reinforcement materials; abdominal wall; Bråck; nät; luciferas; fullhudstransplantat; FTSG; möss; IPOM; onlay; förstärkningsmaterial; bukvägg; Surgery; kirurgi;

    Sammanfattning : Background: Abdominal wall hernia is a common surgically treated condition. Patients with primary umbilical hernia are operated with suture or mesh repair, but recurrence and complication rates have been debated.Larger abdominal wall hernias need implantation of reinforcing material for repair. Synthetic implants are dominating. LÄS MER
