1. 1. Aspects of neonatal intensive care and anesthesia : Thermal balance and respiratory management

   Författare :Victoria Karlsson; Johan Ågren; Lena Hellström-Westas; Filip Fredén; Valeria Perez de Sa; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neonatal; anesthesia; kangaroo-mother-care; skin-to-skin care; carbon dioxide;

   Sammanfattning : This thesis is based on four articles originating from three studies conducted in the neonatal intensive care unit and the children’s operating deparment at Uppsala University Hospital, Sweden.The overall aim was to obtain new knowledge about thermal balance and care environment in extremely preterm infants during skin-to-skin care (SSC), evaluate different methods of intraoperative monitoring of carbon dioxide (CO2), and to investigate how different levels of inhaled oxygen affect infants’ oxygenation during anesthesia and surgery.

3. 2. Modelling and Simulation of Thermal Radiation in Biomass Combustion

   Författare :Thomas Nilsson; Förbränningsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat load; gas turbine; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; porous media; fixed bed; biomass; wood; FG-DVC; combustion; DOM; P1-approximation; Mie theory; RDG-PFA; EWBM; thermal radiation; soot;

   Sammanfattning : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. LÄS MER

4. 3. Ventilerad luftspalt i yttervägg : luftomsättningar och konvektiv fukttransport

   Författare :Jörgen Falk; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Drying time; Strapping; Ventilation drying rate; Air change rate; Thermal balance; Ventilated cavity; Moisture balance; EIFS;

   Sammanfattning : Allvarliga fuktproblem i ytterväggar med regelstomme av trä och fasadskikt av puts på isolering har under senare delen av 2000-talet konstaterats i Sverige. Ett alternativ byggsätt för den putsade fasaden är att putsa mot ett skivunderlag som sitter monterat mot läkt så att en luftspalt bildas. LÄS MER

5. 4. Indoor Thermal Environment in Supermarkets. A study of measured and perceived comfort parameters

   Författare :Ulla Lindberg; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; supermarket; display cabinets; thermal comfort; thermal environment; interdisciplinary;

   Sammanfattning : In the supermarket environment three different groups must be considered: food (food quality), personnel (working conditions) and customers. Customers are of particular interest since they make up the commercial basis for the supermarket. Currently, however, there are no recommendations on the indoor environment for this category.

7. 5. Analysis of PEM Fuel Cell Stacks and Systems with Water/Thermal Balances

   Författare :Takamasa Ito; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; PEM Fuel Cell Systems ; Water Thermal Balances ; Heat Exchangers ; PEM Fuel Cell Stacks ;

   Sammanfattning : The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time, and is regarded as a new energy source for various applications, such as portable, stationary and automotive ones. However, due to the shortage of the infrastructure in the society, the high cost, the difficulty of the water/thermal management, etc. LÄS MER
