1. The mechanism behind internal injector deposits
Master-uppsats, KTH/KemiteknikSammanfattning : Användningen av biobränslen har ökat för att minska utsläppen från fossila bränslen. Biobränslen kan dock leda till beläggningar inuti injektorn, vilka påverkar fordonets körbarhet. LÄS MER
2. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. LÄS MER
3. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. LÄS MER
4. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. LÄS MER
5. Polymerized Tubular Silicates in Lower Cambrian Carbonates – Biology or Chemistry?
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Shallow marine environments from the Lower Cambrian period were very different to shallow marine environments of today. Tubes of what was thought to be silica recovered from a partly dolomitized carbonate sample collected form a site near Indian Springs, Nevada could help further understand the chemistry and characteristics of such environments.
