1. 1. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Melinda Rydberg; [2022]
   Keywords : Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

   Abstract : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

3. 2. Environmental transformation and dissolution of Cobalt- and Nickel-based Nanoparticles in Presence of Eco-corona Biomolecules

   University essay from KTH/Yt- och korrosionsvetenskap

   Author : Anher Saeed; [2021]
   Keywords : Nanoparticles; Cobalt; Nickel; Eco-corona biomolecules adsorption; Metal dissolution; Nanopartiklar; Kobolt; Nickel; Biomolekyler adsorption; Metallfrisättning;

   Abstract : Den ökande trenden med att använda tillverkade nanopartiklar (NPs) i olika tillämpningar i samhället har väckt oro när det gäller deras växelverkan med naturliga ekosystem. Syftet med denna studie är att ta fram data under förhållanden som simulerar realistiska scenarios och syftar till att förstå växelverkan mellan koboltbaserade NPs (Co, Co3O4 och Co SCS) och nickelbaserade NPs (Ni, NiO och Ni SCS) med naturliga nedbrytningsprodukter (biomolekyler, ekokorona) som utsöndras från Daphnia magna.

4. 3. Modelling of contacts in Adams flex bodies using Mamba

   University essay from KTH/Fordonsdynamik

   Author : Shashwat Joshi; [2021]
   Keywords : Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

   Abstract : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. READ MORE

5. 4. The mirror in ancient South Italian funerary context : A study of the mirror’s function and symbolic meaning in graves in the Greek colonies Locri Epizefiri and Metaponto

   University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

   Author : Isabella Jäger; [2021]
   Keywords : Mirror; grave; Locri Epizefiri; Metaponto; contextual archaeology; iconographical analysis; Dionysiac cult; divination;

   Abstract : The mirror appears frequently in funerary contexts in the Greek colonies Locri Epizefiri and Metaponto and this thesis endeavours to rebuild the contexts of these mirrors using the approach of contextual archaeology. To explore the mirror’s contemporary function and meaning within the burial record and to discern why mirrors appear within a funerary setting, a chain of contexts is followed from the archaeological material to iconographical analysis, to comparative archaeological data, widening the contextual circles step by step.
