  1. 1. Gas Exchange in the Normal Lung : Experimental studies on the effects of positive end-expiratory pressure and body position

    Författare :Mats J. Johansson; Sten Walther; Gunnar Nicolaysen; John-Peder Escobar Kvitting; Stefan Lundin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : BACKGROUND: The principal function of the lung is gas exchange requiring adequate ventilation and perfusion at the level of the alveoli. The efficiency of gas exchange is depending on the distributions of regional ventilation (V) and pulmonary blood flow (Q) and their correlation. LÄS MER

    Sammanfattning : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; mining; underground mines; constraint programming; large neighborhood search; korttidsplanering; gruvdrift; underjordsgruvor; villkorsprogrammering; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The mining industry is facing a surge in automation in the pursuit of safe and profitable operations. As the excavation process is increasingly automated, today's mining companies seek to optimize the coordination of the now automated mining activities. LÄS MER

  7. 5. Rosetta Observations of Plasma and Dust at Comet 67P

    Författare :Fredrik Leffe Johansson; Anders Eriksson; Jan-Erik Wahlund; Nicolas André; Uppsala universitet; []

    Sammanfattning : In-situ observations of cometary plasma are not made because they are easy. The historic ESA Rosetta mission was launched in 2004 and traversed space for ten years before arriving at comet 67P/Churyumov-Gerasimenko, which it studied in unprecedented detail for two years. LÄS MER
