21. Galactic archaeology with metal-poor stars
Sammanfattning : The chemical fingerprints of old, metal-poor stars can be used to unravel the events of the newborn Universe and help us understand the properties of the first stars and star clusters. The study of nearby stars to infer properties in the distant past is often referred to as Galactic archaeology. LÄS MER
22. Structured Carbon-Alkaline Earth Metal Halides Composites for Ammonia Storage
Sammanfattning : NOx (NO, NO2) is one of the most harmful air-pollutants from exhaust, resulting in series of environmental problems as well as severe healthy issues for human beings. Selective catalytic reduction (SCR) system is a common approach to eliminate NOx onboard by using ammonia as a reductant. LÄS MER
23. Strong blast wave interaction with multiphase media
Sammanfattning : The interaction of a blast wave propagating in air with different fluids like water column, aqueous foam and thermal/density inhomogeneity have been studied both experimentally and numerically. The blast waves were generated at atmospheric conditions in a newly constructed exploding wire facility. LÄS MER
24. Some Basic Problems in Rock Breakage by Blasting and by Indentation
Sammanfattning : This thesis is devoted to discussing some basic problems in rock breakage by blasting and by mechanical excavation, and contains a detailed summary and six appended papers numbered as Papers A to F. The central problem treated in this thesis is the interaction between either explosion products or mechanical tools and rock. LÄS MER
25. The origin and chemical evolution of iron-peak and neutron-capture elements in the Milky Way disk
Sammanfattning : All the elements heavier than Li are created during stellar evolution. Even if our knowledge of this process is good, many questions still remain. LÄS MER
