  1. 1. Isocyanates - methodology for gas and particle generation, sampling and detection

    Författare :Daniel Gylestam; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Dhimiter Bello; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Isocyanate; PUR; Dry sampler; PTR-MS; Transfer line; PPE; Environmental Chamber; Respirable Particles; Denuder Impactor; Aerosol; Particles; Impinger; air sampling; LC-MS; di-n-butylamine; DBA; ICA; MIC; HDI; TDI; IPDI; MDI; Occupational Exposure; Exposure; Occupational Health; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Isocyanates are mainly used in the industry for the production of polyurethane (PUR) plastics. Workers are at risk of being exposed during the manufacturing of PUR. During thermal degradation of PUR, isocyanates are released and workers involved in hot work such as fire-fighting, welding etc. may also be exposed. LÄS MER

  3. 2. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

    Författare :Christina Isaxon; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Sammanfattning : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. LÄS MER

  4. 3. Exposure to some carcinogenic compounds in air, with special reference to wood smoke

    Författare :Pernilla Gustafson; Göteborgs universitet; []
    Nyckelord :formaldehyde; acetaldehyde; 1; 3-butadiene; benzene; polycyclic aromatic hydrocarbons; particulate matter; domestic wood burning; exposure assessment; personal exposure; experimental study;

    Sammanfattning : The general population is exposed to air pollutants in both indoor and outdoor air from many different sources, including traffic, biomass burning, industries, cigarette smoking, and certain building materials. Air pollutants can cause a variety of health effects such as cancer and respiratory and cardiovascular diseases. LÄS MER

  5. 4. Cold exposure and thermal comfort among patients in prehospital emergency care : innovation research in nursing

    Författare :Jonas Aléx; Britt-Inger Saveman; Stig Karlsson; Ulf Björnstig; Inggard Lereim; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thermal comfort; thermal discomfort; cold exposure; cold stress; hypothermia; patients’ experiences; active warming; prehospital emergency care; finger temperature; back temperature; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : BackgroundPatients’ cold exposure is a neglected problem in prehospital emergency care. Cold stress increases pain and anxiety and contributes to fear and an overall sense of dissatisfaction. When left untreated, cold stress disturbs vital body functions until ultimately reaches hypothermia. LÄS MER

  7. 5. Presence of microemboli during haemodialysis and methods to reduce the exposure to microbubbles

    Författare :Forsberg Ulf; Bernd Stegmayr; Per Jonsson; Ingela Fehrman Ekholm; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; in vivo; microemboli; microbubbles; dialyzer; air trap; venous chamber;

    Sammanfattning : Despite chronic dialysis treatment, patients with end stage renal disease undergoing maintenance haemodialysis (HD) remain at a substantially increased risk of morbidity. Previous reports using Doppler ultrasound (DU) during HD have revealed microembolic signals (ME) in the venous circulation. LÄS MER
