1. Natural Ventilation and Air Infiltration in Large Single‑Zone Buildings : Measurements and Modelling with Reference to Historical Churches
Sammanfattning : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. LÄS MER
2. Levels and sources of organophosphorus flame retardants and plasticizers in indoor and outdoor environments
Sammanfattning : Global consumption of organophosphate esters (OPs), which are used as flame retardants and plasticizers, is rapidly increasing. Their use as additives in diverse applications poses a risk as they may be emitted from the products they are added to and be further transported in the environment. LÄS MER
3. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study
Sammanfattning : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.

4. Safety and biological aspects of present techniques of haemodialysis
Sammanfattning : Introduction: Haemodialysis (HD) is a treatment in which blood from the patient is lead through a tubing system into a dialysis device in a extracorporeal circuit. This circuit contains semipermeable membranes (dialyzer). Blood with uraemic toxins flows on one side, and a salt solution flows on the other side. LÄS MER
5. Presence of microemboli during haemodialysis and methods to reduce the exposure to microbubbles
Sammanfattning : Despite chronic dialysis treatment, patients with end stage renal disease undergoing maintenance haemodialysis (HD) remain at a substantially increased risk of morbidity. Previous reports using Doppler ultrasound (DU) during HD have revealed microembolic signals (ME) in the venous circulation. LÄS MER
