  1. 1. Investigations of Chlorine-Induced High Temperature Corrosion of Steels

    Författare :Nicklas Folkeson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sulphur; alkali; chlorine; field exposures; HCl-induced corrosion; high temperature corrosion; deposits.; chloride-induced corrosion; waste; 310S; HCl;

    Sammanfattning : The high corrosivity of the fireside environment in waste and biomass fired boilers is commonly attributed to the presence of chlorine-containing compounds. Chlorine-induced high temperature corrosion is not well understood, however. LÄS MER

  2. 2. Pulsed Electric Field Food Treatment and Low Frequency Bioelectromagnetics

    Författare :Martin Lindgren; Chalmers University of Technology; []
    Nyckelord :extremely low frequency; non-thermal microbial inactivation; electromagnetic fields; biological effects; treatment chambers; electric field distribution; magnetic fields; pulsed electric fields;

    Sammanfattning : This thesis is divided in two parts, both of which address the interaction between biological cells (especially cell membranes) and electromagnetic fields. The first part deals with the application of intense pulsed electric fields (PEF) in foods. It is intended to be a non-thermal method to inactivate microorganisms. LÄS MER

  3. 3. Fourier Transform Infrared Spectroscopy in Industrial Hygiene Applications : Assessment of Emissions from and Exposures in Wood Processing Industries

    Författare :Urban Svedberg; Christer Edling; Bo Galle; Hans-Erik Högberg; Nils Plato; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; FTIR; Exposure; Emission; Saw mills; Wood pellets; Tracer gas; Monoterpenes; Hexanal; Carbon monoxide; Open path FTIR; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : This thesis evaluates the use of Fourier Transform Infrared Spectroscopy (FTIR) as an approach to the increasingly difficult air sampling challenges within the field of occupational and environmental hygiene. The application of FTIR is exemplified by the assessment of emissions from and exposures in the sawmill and pellet industries. LÄS MER

  4. 4. Atmospheric corrosion and runoff processes on copper and zinc as roofing materials

    Författare :Wenle He; KTH; []
    Nyckelord :atmospheric corrosion; corrosion rate; runoff rate; copper; zinc; field study; laboratory study; roof; first flush; rain quantity; rain intensity; rain pH; dry and wet deposition; corrosion and runoff process;

    Sammanfattning : An extensive investigation with parallel field andlaboratory exposures has been conducted to elucidateatmospheric corrosion and metal runoff processes on copper andzinc used for roofing applications. Detailed studies have beenperformed to disclose the effect of various parameters on therunoff rate including: surface inclination and orientation,natural patination (age), patina composition, rain duration andvolume, rain pH, and length of dry periods inbetween rainevents.

  5. 5. Financial Choice and Public Policy

    Författare :Karin Kinnerud; Per Krusell; Kurt Mitman; Gianluca Violante; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; heterogeneous households; housing; mortgage interest deduction; welfare; monetary policy; mortgage contracts; mortgage lending policies; consumption; pensions; field experiment; search costs; inattention; dominated choices; financial literacy; Economics; nationalekonomi;

    Sammanfattning : Costly reversals of bad policies: the case of the mortgage interest deductionThis paper measures the welfare effects of removing the mortgage interest deduction under a variety of implementation scenarios. To this end, we build a life-cycle model with heterogeneous households calibrated to the U.S. LÄS MER
