  4. 12. Exposure to motor exhaust in the occupational and general environment in Stockholm county

    Author : Marie Lewné; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Exposure measurement; NO2; Particles; EC; diesel exhaust;

    Abstract : In recent years, health hazards associated with air pollution from motor exhaust have received increasing attention. Lung cancer and heart disease have been linked to air pollution exposure. However, the knowledge concerning exposure levels, is insufficient, but is essential for risk assessment. READ MORE

  5. 13. Primitive Direcursion and Difunctorial Semantics of Typed Object Calculus

    Author : Johan Glimming; Karl Meinke; John Power; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; denotational semantics; axiomatic domain theory; coalgebra; primitive co recursion; object-based programming; typed object calculus; Computer science; Datavetenskap; datalogi; Computer Science;

    Abstract : In the first part of this thesis, we contribute to the semantics of typed object calculus by giving (a) a category-theoretic denotational semantics using partial maps making use of an algebraic compactness assumption, (b) a notion of "wrappers'' by which algebraic datatypes can be represented as object types, and (c) proofs of computational soundness and adequacy of typed object calculus via Plotkin's FPC (with lazy operational semantics), thus making models of FPC suitable also for first-order typed object calculus (with recursive objects supporting method update, but not subtyping). It follows that a valid equation in the model induces operationally congruent terms in the language, so that program algebras can be studied. READ MORE

  6. 14. Indoor environment and recurrent wheezing in young children

    Author : Gunnel Emenius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Child; asthma; allergy; wheezing; air pollution; NO2; indoor air quality; building construction; ventilation system; indoor humidity; house dust mites; damp buildings; moisture; moulds; prospective studies; child;

    Abstract : Recurrent wheezing is one of the most common causes of morbidity and hospitalisation among infants and young children in many westernised countries. Respiratory infections and exposure to tobacco smoke have been identified as important risk factors. The indoor environment is also clearly of importance since we spend most of our time indoors.

  7. 15. Effects of nitrogen dioxide on airway responsiveness in allergic asthma

    Author : Victoria Strand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : air pollution; nitrogen dioxide; asthma; allergy; airway responsiveness; pulmonary function; eosinophils; particulates; repeated exposure;

    Abstract : Asthma is one of the most common chronic diseases in the industrialized world and its prevalence is increasing. Clinical symptoms of airway obstruction and bronchial hyper responsiveness can be induced by specific agents, such as allergens and non-specific stimuli, such as cold air and irritants. READ MORE
