1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

2. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

3. Expression of complement factor C1r and C1s in human gingival fibroblasts
Master-uppsats, Umeå universitet/Institutionen för odontologiSammanfattning : Background: Periodontitis is an inflammatory condition rendering in degradation of tooth supporting tissue. In the inflammatory process cytokines, amongst others TNF-a, IL-1b and IL-6 play an important role in regulating the immune response. LÄS MER
4. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. LÄS MER
5. Effects of mixed surfactant system on chemical and physical stability of human growth hormone
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. LÄS MER
