1. 1. Resistance breathing with PEP and CPAP : effects on respiratory parameters

   Författare :Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

   Sammanfattning : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. LÄS MER

3. 2. Assessment of chest physiotherapy in children

   Författare :Anna-Lena Lagerkvist; Göteborgs universitet; []
   Nyckelord :adolescent; airway disease; chest clapping; chest physiotherapy; child; cystic fibrosis; infant; mucus; multiple severe disabilities; non-cooperative; PEP; oscillating PEP; transcutaneous blood gas analysis;

   Sammanfattning : Chest physiotherapy (CPT) is used to improve the lung function and blood gas tensions in individuals with respiratory disease. The aim of this thesis was to assess and compare immediate effects of CPT with positive expiratory pressure (PEP) and oscillating PEP (OscPEP) on blood gas tensions in patients with cystic fibrosis (CF), to assess effects of CPT with PEP in severely disabled children, to describe and evaluate a new CPT method for children who cannot co-operate, and to compare obtained results with chest clapping.

4. 3. The Jovian Plasma Dynamics and Composition Analyzer (JDC) for ESA's JUICE Mission

   Författare :Philipp Wittmann; Martin Wieser; Stas Barabash; Krister Wiklund; Frédéric Allegrini; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; JUICE mission; positive ions; negative ions; electrons; time-of-flight; time-of-arrival; PEP; JDC; CEM; channel electron multiplier; pressure; instrument development; calibration; TOF; TOA; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

   Sammanfattning : This dissertation covers the development and calibration of the Jovian plasma Dynamics and Composition analyzer (JDC). JDC is together with five other sensors a part of the Particle Environment Package (PEP), one of the payloads of the European Space Agency's JUpiter ICy moons Explorer (JUICE) mission. LÄS MER

5. 4. Advanced Plasma Analyzer for Measurements in the Magnetosphere of Jupiter

   Författare :Joan Stude; Stas Barabash; Martin Wieser; Joseph H. Westlake; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plasma instrumentation; time-of-flight; space; Jupiter; JUICE; PEP; JDC; start surface; charge fraction; the final frontier; accidental counts; chance counts; micro pore optics; spherical-wedge electrostatic analyzer; rymd- och plasmafysik; Space and Plasma Physics; fysik; Physics;

   Sammanfattning : The Jupiter Icy Moons Explorer is a planetary exploration mission that aims to study the moons of Jupiter in the planet’s vast magnetosphere. Among the various instruments on board is the Particle Environment Package (PEP), that is led by the Swedish Institute of Space Physics (IRF) in Kiruna. LÄS MER

7. 5. Regulation of chloroplast development during the greening process

   Författare :Yan Ji; Åsa Strand; Eevi Rintamäki; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; light response; anterograde signalling; plastid transcription; chloroplast development; photosynthesis; bZIP; PEP complex; de-etiolation; molekylärbiologi; Molecular Biology;

   Sammanfattning : Upon light exposure, the expression of one-third of the nuclear-encoded genes is changing, including genes encoding many chloroplast-targeted proteins responsible for the initiation of plastid transcription and the establishment of photosynthesis. The control of the nuclear-encoded genes involved in the development of chloroplast is referred to as anterograde signalling. LÄS MER
