Best practice in design and testing of isolation rooms in Nordic hospitals (NT TR 564)

NT TR 564

  • An important step in moving toward international standardization is to come to a consensus about what exactly is proper and adequate function in a negative-pressure isolation room. In this report we examine current and best practice in design and performance testing of negative pressure isolation rooms in Nordic hospitals.

Biodegradability testing of the municipal solid waste reject (NT TR 560)

NT TR 560

  • Sustainable development requires an environmentally sound, cost effective and socially acceptable management of municipal and industrial waste. Landfilling of untreated municipal solid waste (MSW) is known to lead to emissions of leachate and landfill gas, above all methane, which contributes to the greenhouse effect.

Biotests and guidelines for investigations of biochemical disorders based upon characterisation of pollutants in landfill leachates (NT TR 518)

NT TR 518

  • The objective of this project is to investigate if leachate from Norwegian landfills affect the reproductive system in fish, similar to what is found in Lake Molnbyggen in Sweden, and to evaluate and, if necessary, to adapt existing tests for biological characterisation of leachate to see whether they are suitable for detecting such disorders.

Buktningsprovning av marmor för fasadbeklädnad (NT TR 481)

NT TR 481

  • Facade cladding of marble has, in several cases, suffered from problems with bowing panels that also loose strength. When not exchanged or repaired there is an obvious risk of panels falling down with time. The project objectives are to develop a laboratory test method for the detection of marble with a potential risk of bowing and to develop a field site investigation method.
