1. Energy performance of multifamily buildings : building characteristic and user influence
Sammanfattning : Today many professional property holders use different types of software for monthly energy analyses. The data is however often limited to energy and water use, that is paid for by the property holder. In year 2001, financed by the Swedish Energy Agency, the first steps were taken to create a national web based data base, eNyckeln. LÄS MER
2. Experimental Investigation of the Influence of Local Flow Features on the Aerodynamic Damping of an Oscillating Blade Row
Sammanfattning : The general trend of efficiency increase, weight and noise reduction has derived in the design of more slender, loaded, and 3D shaped blades. This has a significant impact on the stability of fan, and low pressure turbine blades, which are more prone to aeroelastic phenomena such as flutter. LÄS MER
3. Friction in threaded fasteners : Influence of materials and tooling
Sammanfattning : Threaded fasteners represent the most common type of machine element, with a unique function that facilitates ease of assembly and disassembly. This ease of disassembly allows machine parts to be reused, refurbished, and recycled. LÄS MER
4. Transvascular fluid exchange with application to the brain. An experimental study in cat skeletal muscle and brain
Sammanfattning : This study evaluated transcapillary fluid exchange in the cat brain and in a cat skeletal muscle enclosed in a plethysmograph. A method for determination of capillary permeability (capillary filtration coefficient and reflection coefficient) and effects of transcapillary hydrostatic pressure changes were studied We found that capillary fluid permeability in a tissue can be determined by the capillary filtration coefficient, even when arterial pressure and vascular tone are changed.

5. Hygro- and hydroexpansion of paper : Influence of fibre-joint formation and fibre sorptivity
Sammanfattning : Paper is a versatile, cheap and environment-friendly material. Nevertheless, there are several factors limiting its usefulness, and one of the major issues is that cellulosic and ligno-cellulosic fibres spontaneously sorb water. At the same time, the water uptake changes the dimensions of the paper. LÄS MER
