  2. 21. Studies on nitric oxide in the respiratory system

    Author : Ulla Schedin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : nitric oxide; endogenous; respiratory system; neonate; prematureinfant; animal; primate; elephant; chemiluminescence; electrochemical; nitrogen dioxide; trachea; nose; ;

    Abstract : Nitric oxide (NO) is formed in biological tissues and has regulatory functions in many organ systems. Endogenous NO has been found in exhaled air and NO is considered to have effects on the pulmonary circulation and bronchial tone, and to be one of the mediators for the circulatory adaptation at birth.

  4. 22. In situ investigations of the metal/atmophere interface

    Author : Teodor Aastrup; KTH; []
    Keywords : ;

    Abstract : This thesis presents a new experimental setup for surfaceanalysis studies, incorporating chemical information frominfrared reflection absorption spectroscopy (IRAS) andquantitative information from quartz crystal microbalance(QCM). The integrated IRAS/QCM surface analysis system enablesin situstudies to be conducted of the metal/atmosphereinteraction on a sub-monolayer level. READ MORE

  5. 23. Fabrication, functionalization and electrical conductance modulation of nanoparticle based molecular electronic Nano-devices

    Author : Ishtiaq Hassan Wani; KLAUS LEIFER; Silvia Karthäuser; Uppsala universitet; []
    Keywords : Molecular electronics; gas sensor; hybrid materials; place exchange; random telegraph signal;

    Abstract : Over the years many techniques have been proposed for the purpose of the formation of electrically conducting metal-molecule-metal junctions. One such technique utilizes gold-nanoparticles (AuNPs) that could assist in contacting small molecules between large gaps. READ MORE

  6. 24. Nasal reactions and the school environment : Nasal patency and lavage biomarkers in relation to ventilation, cleaning and some indoor air pollutants

    Author : Robert Wålinder; Uppsala universitet; []
    Keywords : Medical sciences; acoustic rhinometry; enviromnental illness; eosinophil cationic protein ECP ; formaldehyde; lysozyme; mold; nasallavage; nasal obstruction; N02; rhinitis; school; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : In Sweden, 2 million persons are exposed to the school environment, and there has been reports on insufficient cleaning, and inadequate ventilation. The nasal mucosa is more easy to study than the lower airways, and rhinitis is common and possibly related to asthma. READ MORE

  7. 25. Asthma, rhinitis, and asthma-related symptoms in relation to vehicle exhaust using different exposure metrics

    Author : Lars Modig; Bertil Forsberg; Lars Barregård; Umeå universitet; []
