1. 21. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling

   Författare :Ramin Ghorbani; Florian M. Schmidt; Anders Blomberg; Christoffer Boman; Staffan Schedin; Jonathan Beauchamp; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon monoxide CO ; pulmonary gas exchange; computational modeling; real-time breath gas analysis; single-exhalation profile; laser absorption spectroscopy; nonlinear least-squares fitting; breath sampling; baseline level; diurnal variation; healthy population; exposure study; fysik; Physics; Physiology; fysiologi;

   Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

3. 22. Detecting Inclusions in a Silicone Rubber Phantom Using Standing Lamb Waves and Multiple Frequency Footprints

   Författare :Ulf G Jonsson; Britt Andersson; Olof A Lindahl; Jacques Ohayon; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezoelectric; Silicone rubber; Impedance; Resonance; Lamb waves; Phantom; Electronics; elektronik;

   Sammanfattning : The thesis deals with one major question: is it possible, using one piezoelectric sensor/vibrator, to detect a hard inclusion in a silicone rubber phantom? The question was approached with an open mind and the task was subdivided into three clearly identifiable parts: characterization of the piezoelectric sensor/vibrator (paper I), creating a model of the visco-elastic properties of a tissue-like material (phantom) in contact with the sensor/vibrator (paper II), and to detect the presence of a hard inclusion in the phantom (paper III). All vibrations of the sensor/vibrator and phantom was modeled using a finite element method (FEM). LÄS MER

4. 23. Samverkan för innovation : En fallstudie av mötet mellan akademi, industri och sjukvård

   Författare :Ylva Askfors; Björn-Erik Erlandsson; Tina Karrbom Gustavsson; Lucia Crevani; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; samverkan; innovation; interorganisatorisk; transdisciplinär; hälso- och sjukvård; medicinteknik; Tillämpad medicinsk teknik; Applied Medical Technology;

   Sammanfattning : Samverkan kan leda till innovation, konkurrenskraftiga företag, förstklassig forskning samt välfungerande myndigheter och institutioner. I den politiska debatten idag finns en förväntan att Sverige ska upprätthålla sin konkurrenskraft och bemöta samhällets utmaningar genom innovation och att vägen till innovation går via samverkan.

5. 24. Advancing portable, aqueous drug delivery to the human lung

   Författare :Torben Last; Göran Stemme; Niclas Roxhed; Claus-Michael Lehr; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Portable Inhaler; Biopharmaceuticals; Soft-mist inhaler; Transport vesicles; Microfluidic packaging; High-pressure microfluidics; aerosolization; cleanroom-free fabrication; drug delivery; micro-electromechanical systems MEMS ; Applied Medical Technology; Tillämpad medicinsk teknik;

   Sammanfattning : Lung disease profoundly impacts human health: many lung diseases are currently without cure and require continued treatment. Due to their ease of use and integration into the daily routine, portable inhalers are the preferred treatment option for patients. LÄS MER

7. 25. Wearable Solutions for P-Health at Work : Precise, Pervasive and Preventive

   Författare :Ke Lu; Kaj Lindecrantz; Afshin Samani; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wearable technology; occupational health; energy expenditure; smart textile; Tillämpad medicinsk teknik; Applied Medical Technology;

   Sammanfattning : With a demographic change towards an older population, the structure of the labor force is shifting, and people are expected to work longer within their extended life span. However, for many people, wellbeing has been compromised by work-related problems before they reach the retirement age. LÄS MER
