1. 6. Determination of benzene in urine and breath for monitoring of benzene exposure

   Författare :Göran Ljungkvist; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological monitoring; benzene; breath; urine; dynamic headspace; membrane; gas chromatography; mass spectrometry; thermal desorption;

   Sammanfattning : The aim of this work was to develop and validate methods for determination of unmetabolized benzene in breath and urine. The methods were intended for the bio monitoring of benzene to assess both occupational and environmental exposure.A method was developed for the determination of benzene in end-exhaled air. LÄS MER

3. 7. Analysis of Endogenous Particles in Exhaled Air

   Författare :Ann-Charlotte Almstrand; Göteborgs universitet; []
   Nyckelord :exhaled particles; time-of-flight secondary ion mass spectrometry; OPLS; airway closure; exhaled breath condensate; glutathione;

   Sammanfattning : Exhaled air contains non-volatile particulate material from the respiratory tract. The precise location in which exhaled particles are formed is unknown, and details on their chemical content are scarce. The aim of this work was to chemically characterize and to study the mechanisms of formation of endogenous particles in exhaled air. LÄS MER

4. 8. Mindfulness-Based Cognitive Therapy in Primary Care: Clinical Applications and Analysis of the Five Facet Mindfulness Questionnaire (FFMQ)

   Författare :Josefine Lilja; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mindfulness; Five Facet Mindfulness Questionnaire FFMQ ; internal consistency; factor structure; cluster analysis; meditators; non-meditators; Mindfulness-Based Cognitive Therapy MBCT ; Primary Care; thematic and benchmarking analysis;

   Sammanfattning : The overall objective of this thesis is to analyse the concept of mindfulness as measured by the Five Facet Mindfulness Questionnaire (FFMQ) and its clinical usefulness in primary care through group Mindfulness-Based Cognitive Therapy (MBCT). Because no Swedish version of the FFMQ was available, that became the starting point of this research project. LÄS MER

5. 9. On a journey for survival : everyday life during radiation therapy from the perspectives of women with breast cancer and their families

   Författare :Annette Holst-Hansson; Malmö universitet; []
   Nyckelord :Breast cancer; Radiation therapy; Content analysis; Hermeneutic phenomenology; Thematic analysis;

   Sammanfattning : This thesis focuses on women diagnosed with breast cancer and their familymembers. Since a breast cancer diagnosis and its subsequent treatment are astrenuous experience not only for the woman afflicted but also for her familymembers, this thesis aimed to explore the experiences of everyday life duringradiation therapy from the perspectives of the woman with breast cancer andher family, as well as exploring families’ experiences of participating in shortfamily health conversations (SFamHC).

7. 10. Improved breath alcohol analysis with use of carbon dioxide as the tracer gas

   Författare :Annika Kaisdotter Andersson; Mikael Ekström; Bertil Hök; Göran Hedenstierna; Johannes Lagois; Mälardalens högskola; []
   Nyckelord :elektronik; Electronics;

   Sammanfattning : State-of-the-art breath analysers require a prolonged expiration into a mouthpiece to obtain the accuracy required for evidential testing and screening of the alcohol concentration. This requirement is unsuitable for breath analysers used as alcolock owing to their frequent use and the fact that the majority of users are sober drivers; as well as for breath testing in uncooperative persons.
