  1. 1. Experimental and Clinical Studies on Contact Allergy to Diphenylmethane-4,4′-diisocyanate and Related Substances

    University dissertation from Lund University, Faculty of Medicine

    Author : Haneen Hamada; Lunds universitet.; Lund University.; [2017]
    Keywords : 4; 4′-MDI; freund s complete adjuvant; Guinea pig maximization test; 4; 4 -MDA; 4; 4 -DMDA; 4; 4 -DMDI; PPD; p-phenylenediamine; 2; 4-TDI; Toluene diisocyanate; trimer; FCA; Cross-reactivity; dermal uptake; contact allergy; contact dermatitis;

    Abstract : The exposure to isocyanates is more of an occupational problem than a consumer problem. The main route of exposure is assumed to be through inhalation. Isocyanates that have high vapor pressure, such as TDI, can be airborne at room temperature. Other isocyanates such as MDI are volatile only when heated. READ MORE

  2. 2. The missing pillar: exploring social sustainability in product development

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Patricia Lagun Mesquita; Blekinge Tekniska Högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; strategic sustainable development; social sustainability; sustainable product development; social lifecycle assessment; social sustainability criteria;

    Abstract : Companies are increasingly pressed to consider sustainability aspects when making decisions during product development. However, the methodological support for doing so is immature. The immaturity is particularly pronounced regarding the social dimension (or pillar) of sustainability and regarding strategic sustainability considerations. READ MORE

  3. 3. Delay-sensitive wireless communication for cooperative driving applications

    University dissertation from Halmstad : Halmstad University Press

    Author : Annette Böhm; Högskolan i Halmstad.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative driving applications; wireless communication;

    Abstract : Cooperative driving holds the potential to considerably improve the level of safety and efficiency on our roads. Recent advances in in-vehicle sensing and wireless communication technology have paved the way for the development of cooperative traffic safety applications based on the exchange of data between vehicles (or between vehicles and road side units) over a wireless link.

    Abstract : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. READ MORE

  5. 5. Some properties of measures of disagreement and disorder in paired ordinal data

    University dissertation from Örebro : Örebro university

    Author : Hans Högberg; Örebro universitet.; [2010]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; agreement; augmented ranks; categorical data; disorder; jackknife; paired ordinal data; rating scales; sample size; sampling distribution; simulation; U-statistics; variance; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES Statistics; computer and systems science Statistics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Statistik; Statistics; Statistik;

    Abstract : The measures studied in this thesis were a measure of disorder, D, and a measure of the individual part of the disagreement, the measure of relative rank variance, RV, proposed by Svensson in 1993. The measure of disorder is a useful measure of order consistency in paired assessments of scales with a different number of possible values. READ MORE
