1. 1. Connecting CMR and Physiology : Expanding the capabilities of cardiovascular magnetic resonance in quantifying physiology

   Författare :Felicia Seemann; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulär magnetresonanstomografi; Fysiologi; Atrioventrikulär klaffplansrörlighet; Mitralisflöde; Tryck-volym loopar; Kraft-längd loopar; Cardiovascular magnetic resonance; Physiology; Atrioventricular plane displacement; Transmitral flow; pressure-volume loops; Ventricular force-length loops;

   Sammanfattning : The assessment of cardiovascular physiology is crucial to facilitate clinical diagnostics, treatment, and research. Physiology and anatomy can be assessed noninvasively using cardiovascular magnetic resonance (CMR), a versatile and reliable medical imaging modality free from ionizing radiation. LÄS MER

3. 2. Individual Metering and Charging of Heat and Hot Water in Multi-Apartment Buildings

   Författare :Simon Siggelsten; Byggproduktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat; hot water; cost allocation; multi-apartment buildings; energy savings.;

   Sammanfattning : Individual metering and charging (IMC) means that tenants in multi-apartment buildings should pay only for their own energy consumption, which gives an economic incentive for energy-conscious behaviour. In April, 2014, Swedish legislation about energy metering in buildings (SFS 2014:267) was passed by the Swedish Parliament as an implementation of the EU Energy Efficiency Directive 2012/27/EU.

4. 3. Attenuation correction in pulmonary and myocardial single photon emission computed tomography

   Författare :Helén Almquist; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; tomography; medical instrumentation; radiology; Clinical physics; downscatter; myocardial perfustion; ventilation-perfusion ratio; radiologi; pulmonary density; pulmonary perfusion; attenuation correction; SPECT; transmission measurement; tomografi; medicinsk instrumentering;

   Sammanfattning : The objective was to develop and validate methods for single photon emission computed tomography, SPECT, allowing quantitative physiological and diagnostic studies of lung and heart. A method for correction of variable attenuation in SPECT, based on transmission measurements before administration of an isotope to the subject, was developed and evaluated. LÄS MER

5. 4. 99mTc-DMSA renal scintigraphy in the diagnosis and follow-up of acute pyelonephritis in children

   Författare :Lena Wallin; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; progressive renal damage; kidney length; kidney radioactive uptake; pyelonephritis; DMSA-scintigraphy; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Sammanfattning : The aim of the present thesis was to define and evaluate a strategy for identification of children who are at risk of developing progressive renal lesions after acute pyelonephritis. Tc-DMSA renal scintigraphy is widely accepted as the most sensitive method for detecting parenchymal lesions and diagnosing acute pyelonephritis. LÄS MER

7. 5. Laser Diagnostics Applied to Lean Premixed Swirling Flames - Simultaneous Flow Field and Scalar Measurements

   Författare :Per Petersson; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volumetric Velocimetry; Low-swirl Flames; Premixed Flames; Turbulent Combustion; Particle Image Velocimetry; Laser Diagnostics; A.2014:Petersson; Combustion Diagnostics;

   Sammanfattning : The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. LÄS MER
