1. Återvinning av hårdmetallstift : En studie av hårdmetallstiftens livscykel och hur volframet i stiften återvinns
Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : I det moderna samhället finns det ett stort behov av metaller och mineraler som används i allt från mobiltelefoner till bilar. Dessa mineraler och metaller finns under marken och behöver grävas upp och genomgå förädlingsprocesser för att användas. LÄS MER
2. Sveriges första synnerligen försvårande omständighet - strider den mot legalitetsprincipen?
Kandidat-uppsats, Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakultetenSammanfattning : In the last decade Sweden has seen a steady increase in the usage of fi-rearms and explosives to settle disputes between local street gangs. These groups predominantly operate in socio-economically disadvantaged areas where members often gradually drift into a criminal lifestyle. LÄS MER
3. Methodologies for training detection dogs and scent sample storing
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical SciencesSammanfattning : Dogs’ spectacular sense of smell has been used as a detection tool by humans in many areas. Their olfaction was first used as a hunting tool, but dogs’ detection skills have been shown to also be applicable in, for example, detection of drugs, explosives, and firearms as well as disease detection.

4. Some Like It Hot: Pre-heating Prior to Bioreactor Treatment Enhances Nitrogen Removal From Mine Drainage
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Ammonium-nitrate based explosives (NH4NO3) used within the operations of Kiruna iron ore mine release nitrate (NO3-) into the environment, potentially having adverse effects on local river-systems. One way of reducing NO3- impacts to the environment is through a woodchip denitrifying bioreactor (DBR). LÄS MER
5. Thermal Initiation of Energetic Materials Caused by Hot Fragments
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : The cause of unintentional initiations of energetic materials is an important area of study due to the risks that comes with storing energetic materials such as high explosives. The current models used to simulate the process of heating energetic materials by a hot metal fragment do not give reliable predictions. LÄS MER
