   Sammanfattning : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. LÄS MER

3. 2. A new generation of hospital operating room ventilation

   Författare :Parastoo Sadeghian; Sasan Sadrizadeh; Catherine Noakes; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventilation systems; bacteria-carrying particles; airflow behaviour; operating room; computational fluid dynamics; surgical site infection; Ventilationssystem; bakteriebärande partiklar; luftflödesbeteende; operationsrum; numerisk strömningsmekanik; kirurgirelaterad infektion; Strömnings- och klimatteori; Fluid and Climate Theory;

   Sammanfattning : Surgical site infection is responsible for 38 percent of reported infections after surgery. This infection increases mortality and treatment costs, and prolongs the hospitalization of patients. LÄS MER

   Sammanfattning : Indoor air quality directly affects the comfort, performance, and well-being of occupants. Indoor pollution can cause immediate or long-term health effects and has been responsible for 4.1% of global deaths in recent decades. LÄS MER

5. 4. Predicting flow-generated noise from HVAC components

   Författare :Oscar Kårekull; Mats Åbom; Gunilla Efraimsson; Joachim Golliard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow noise; noise prediction; HVAC; flödesalstrat ljud; bullerprediktion; HVAC;

   Sammanfattning : More energy efficient fans, i.e. larger sizes running at lower speeds, in Heating Ventilation and Air Conditioning (HVAC) systems decrease the fan noise and increase the importance of flow generated noise in other system components, e.g. LÄS MER

7. 5. On the performance of stratified ventilation

   Författare :Ulf Larsson; Bahram Moshfegh; Per Heiselberg; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : People nowadays spend most of their time indoors, for example in their homes, cars, in trains, at work, etc. In Sweden, the energy demand in the built environment is a growing issue. LÄS MER
