Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)Sammanfattning : One of the modern times worst environmental problem are polluted water resources. An example of source of pollution to water resources are, heavy metal leached from acid sulfate soils (ASS). LÄS MER
32. Methods for verification of ultra-pure water with air gap membrane distillation : Focusing on applications in the semiconductor industry
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : In the semiconductor industry, the purification process of the silicon wafers is of a great importance. If water of sufficient quality is not used, the silicon wafer surface runs a risk of being destroyed by particles and bacteria sticking to its surface. LÄS MER
33. CFD study and method development for air intake systems using OpenFOAM
Master-uppsats, KTH/Teknisk mekanikSammanfattning : This report is the result of a joint collaboration between the two Swedish companies AFRY and Scania AB. The need of CFD analyses for internal flow purposes are continuously increasing in companies like Scania. However the use of CFD software is limited to license costs. LÄS MER
34. Life cycle assessment of DHA produced by microalgae using food waste : Assessing global warming, fossil energy use and effects on biodiversity
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Biodiversity is a key component for life on Earth since it contributes to clean water, fresh air and food security. Today, fatty fish farmed in aquaculture is the main Omega 3 source consumed by humans, including the essential fatty acid docosahexaenoic acid (DHA).

35. Kartläggning av förekomst av mikroorganismer i produktionslokaler där läkemedlet Xylocaingel produceras
Kandidat-uppsats, Karlstads universitetSammanfattning : Kontamination med mikroorganismer är något som sker ständigt och i samband med läkemedelsproduktion kan de bidra till försämringar av produktens kvalité. Genom att kontrollera den mikrobiella floran i bland annat aktuella lokalers luft och ytor uppfyller läkemedelsproducenterna kraven enligt Good Manufacturing Practice. LÄS MER
