16. Optical Diagnostics of Soot in Combusting Sprays
Sammanfattning : Optical diagnostics in combusting diesel sprays were carried out in the Chalmers High Pressure, High Temperature (HP/HT) spray rig at conditions similar to those in an internal combustion engine, reaching up to 100 bar and 630 ◦ C. Spray development studies and combustion characterisation were done by high speed shadowgraphs that were digitally processed to measure the start of combustion, break-up, droplets and vapour penetration.

17. Compression uniformity measurements on coated anduncoated paper surfaces
Sammanfattning : Paper is exposed to compressive stresses at several occasions in its production process and in subsequent printing operations. In the press section of a paper machine, the fibre web is mechanically dewatered by compression. LÄS MER
18. Alpha-radioimmunotherapy with At-211: Evaluations and imaging on normal tissues and tumors
Sammanfattning : Alpha-radioimmunotherapy (alpha-RIT) is an internal conformal radiotherapy at the cellular level using alpha-particle emitting radionuclides. Alpha-particles have a very short range in tissues (... LÄS MER
19. An experimental study of fiber suspensions between counter-rotating discs
Sammanfattning : The behavior of fibers suspended in a flow between two counter-rotating discs has been studied experimentally. This is inspired by the refining process in the papermaking process where cellulose fibers are ground between discs in order to change performance in the papermaking process and/or qualities of the final paper product.

20. Experimental Investigation of Cavitation-Bubble-Induced Atomization
Sammanfattning : Improving the efficiency and lowering the emissions of internal combustion engines (ICE) has been drawing increased attention because climate change caused by greenhouse gases and the need to reduce emission harmful to human health, and stricter legislation on the emissions from liquid-fueled transportation is implemented. Design of the liquid fuel atomizer, which atomizes the fuel delivered into the combustion chamber by the fuel injection system, is important because a good atomization, which facilitates the evaporation of fuel and improves the fuel-air mixture, leads to higher efficiency and lower emissions of ICE.
