    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bullying; measurement methods; pedagogical leadership; psychosomatic health; Rasch analysis; Mobbning; mätmetoder; pedagogiskt ledarskap; psykosomatisk hälsa; Rasch analys; Public Health Science; Folkhälsovetenskap;

    Sammanfattning : The aim of this thesis is to explore methods for assessing peer victimization and pedagogical leadership in school.The thesis includes four studies. Study I and II are based on web-based questionnaires among 2, 568 students in grades 7, 8 and 9. LÄS MER

  3. 2. Chemical emissions from concrete

    Författare :Kristina Hjellström; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; miljöpåverkan; mätmetoder; emissioner; flyktiga organiska föroreningar; betong; VOC; emissionsmätningar;

    Sammanfattning : The major part of this work deals with a new method for quantification of VOCs in concrete. There is a need for this type of quantification due to the development in cement and concrete production using plasticizing agents and fillers for improved rheological properties, and alternative fuels and waste materials to reduce the environmental impact of cement production.

  4. 3. Methods of measuring the moisture diffusivity at high moisture levels

    Författare :Mårten Janz; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fukttransport; materialegenskaper; permeabilitet; teori; beräkningsmetoder; mätmetoder; byggmaterial; forskningsresultat;

    Sammanfattning : The purpose of this licentiate study is to analyze capillarity transport in building materials, and in order to do that, develop a new measurement method by which the moisture diffusivity at high moisture levels can be measured in an easy way.... LÄS MER

  5. 4. Calorimetric methods for the study of fungi on building materials

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

    Sammanfattning : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. LÄS MER

  7. 5. Putsens inverkan på fasadens fuktbalans

    Författare :Kenneth Sandin; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rendering; moisture; driving rain; absorption; drying; provningsmetoder; mätmetoder; kondens; slagregn; fukt; ytterväggar; puts; fasader; pore structure; surface coating; diffusion;

    Sammanfattning : The report deals with the effect of renderings on the moisture balance in facades. The main therne is the moisture mechanism in cnnnection with different moisture sources. Different opinions about moisture in facades and consequences of moisture are mentioned as a background. LÄS MER
