  1. 21. Cracking in concrete : crack prevention with air-cooling and crack distribution with steel fibre reinforcement

    Författare :Patrik Groth; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : This Licentiate Thesis consists of four parts. The first two parts, paper A and B, deal with air-cooling by means of embedded pipes in order to reduce thermal cracking in concrete structures. These two papers are submitted for publication to RILEM Journal; ‘Materials and Structures'. LÄS MER

  3. 22. Polarization transfer solid-state NMR for studying soft matter: From surfactants to the stratum corneum

    Författare :Agnieszka Nowacka; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The work presented in this thesis is dedicated to theoretical development, experimental testing and application of polarization transfer solid-state nuclear magnetic resonance (PT ssNMR). PT ssNMR is an analytical tool which provides detailed information about molecular mobility in model or simple soft matter systems at the low water content regime, enabling the creation of phase diagrams.

  4. 23. Methods for mechanical testing based on analysis of elastic waves in rods

    Författare :Janne Carlsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : This thesis summarizes six papers on development and applications of a method to evaluate the normal force and particle velocity at any cross-section of a nonuniform rod from measurements of strain at two different cross-sections. In Paper A the method is developed. It is an extension of that developed by Lundberg and Henchoz for uniform rods. LÄS MER

  5. 24. Identification and characterization of new mechanisms in cardiovascular estrogen signaling

    Författare :Anders Holm; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endothelial cells; vascular smooth muscle cells; estrogen; GPR30 GPER1; inflammation; calcium; neovascularization; microtubule;

    Sammanfattning : Women before menopause are protected from cardiovascular disease compared to age-matched men through mechanisms associated with the female sex hormone estrogen. There are three known estrogen receptors named ERα, ERβ and GPR30/GPER1, which are all three receptors are expressed in the cardiovascular system. LÄS MER

  7. 25. Predicting flow-generated noise from HVAC components

    Författare :Oscar Kårekull; Mats Åbom; Gunilla Efraimsson; Joachim Golliard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow noise; noise prediction; HVAC; flödesalstrat ljud; bullerprediktion; HVAC;

    Sammanfattning : More energy efficient fans, i.e. larger sizes running at lower speeds, in Heating Ventilation and Air Conditioning (HVAC) systems decrease the fan noise and increase the importance of flow generated noise in other system components, e.g. LÄS MER
