  2. 1. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories

    Author : Imran Khan; Lars Håkansson; Ingvar Claesson; Josef Ström Bartunek; Gustavo R. Alves; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

    Abstract : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. READ MORE

  4. 2. Bioassay analysis of dioxin-like compounds : response interactions and environmental transformation of Ah receptor agonists

    Author : Helena Olsman; Magnus Engwall; John P. Giesy; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioassay; dioxin-like; Ah receptor; Biology; Biologi; Biology; Biologi;

    Abstract : Dioxin-like compounds mediate their toxicity by binding to the aryl hydrocarbon receptor (AhR) and through this receptor a cascade of biochemical and toxic events are triggered. Mechanism-specific dioxin bioassays utilise the AhR coupled induction of endogenous CYP1A proteins or reporter gene systems for detection of dioxin-like compounds and other AhR ligands. READ MORE

  5. 3. Methodological support for strategic sustainable development work in municipalities and regions

    Author : Lisa Wälitalo; Göran Broman; Karl-Henrik Robèrt; Edith Callaghan; Tony Svensson; Blekinge Tekniska Högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainability; strategic sustainable development; cross-sectoral collaboration; action research; municipalities and regions; methodological support; Strategic Sustainable Development; Strategisk hållbar utveckling;

    Abstract : Municipal and regional actors have key roles to play in society’s transition to sustainability. However, co-creating sustainable visions and effective governance towards these is a complex challenge and decision-makers often lack an overarching systems perspective. READ MORE

  6. 4. Noise and Vibration Control of Combustion Engine Vehicles

    Author : Mathias Winberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Noise and vibrations have over the last two decades been regarded as significant environmental health problems. Regulations regarding acoustic as well as vibration levels have therefore become more stringent. READ MORE

  7. 5. Effects of surfactant adjuvants on plant leaf cuticle barrier properties

    Author : Anton Fagerström; Malmö högskola; []
    Keywords : Adjuvant; Surfacant; Cuticle; Tebuconazole; Diffusion; Clivia miniata Regel leaf; Model wax; Phase diagram; Hydration; Eutectic melting; Crystalline domains; Softening; Wax film; Quartz Crystal Microbalance with dissipation QCM-D ; Differential Scanning Calorimetry DSC ; Small- and Wide-angle X-ray Diffraction SWAXD ;

    Abstract : I avhandlingen undersöks växelverkan mellan det yttersta lagret på växters blad (cutikeln), aktiva substanser, och ämnen som tillsätts för att öka bekämpningsmedlens effekt, i detta fall vissa former av tensider. Barriären som hindrar upptag av främmande ämnen i växten sitter i cutikeln. READ MORE
