2. Energy Efficiency Improvements of Tumble Dryers : -Technical Development, Laundry Habits and Energy Labelling
Abstract : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity. READ MORE

4. CFD as a tool for analysis of complex geometry : Perspectives on time efficient simulations of interior household appliance components
Abstract : Throughout recent years, computer based programs has been applied to solve and analyze industrial problems. One of these developed programs is the Computational Fluid Dynamics (CFD) program. The purpose of implementing CFD analysis is to solve complex flow behavior which is not possible with ordinary calculus. READ MORE

5. Survival of infectious agents and detection of their resistance and virulence factors
Abstract : In the first study, three different transport systems for bacteria were evaluated. The CLSI M40-A guideline was used to monitor the maintenance of both mono- and polymicrobial samples during a simulated transportation at room temperature that lasted 0-48 h. READ MORE
