  1. 1. Evaluation of antioxidant effect of an algae extract on skin: in vitro study

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Oday Al Mustafa; [2023]
    Keywords : Algae extract; antioxidant; DPPH; microalgae; ROS; skin covered oxygen electrode; skin;

    Abstract : Algae extracts are used as cosmetic products and used as additives in specific foods because of their antioxidant activity. Reactive oxygen species (ROS) such as hydrogen peroxide and superoxide radicals are toxic on the skin and can be scavenged by antioxidants, which are abundant in microalgae. READ MORE

  3. 2. Temporal, climatic and spatial variation in the distribution and activity patterns of the raccoon (Procyon lotor) in Hainich National Park, Germany

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Maria Grüneberger; [2022]
    Keywords : raccoon; procyon lotor; hainich National Park; canopy Walk; camera trapping; nocturnality; ground temperature; habitat preference; european beech; fagus sylvatica; anthropogenic influence;

    Abstract : The raccoon (Procyon lotor) has been a part of German fauna since the 1920s, following a number of releases and escapes from captivity. This study intends to investigate the distribution and activity patterns of this non-native mesopredator in Hainich National Park, which lies in Central Germany, in-between 3 core areas of established raccoon populations.

  4. 3. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Emma Flodin; [2022]
    Keywords : Geochemistry; gypsum; HFO; adsorption; scavenged; critical elements; beryllium; Yxsjöberg; mine waste; Sequential extraction; XRD; SEM-EDS;

    Abstract : 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. READ MORE

  5. 4. Oil Autonomy of a Turbojet

    University essay from KTH/Flygdynamik

    Author : Florian Steiner; [2022]
    Keywords : Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

    Abstract : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. READ MORE

  6. 5. Modeling of Fuel Dynamics in a Small Two-Stroke Engine Crankcase

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Johan Andersson; Oscar Wyckman; [2015]
    Keywords : Modeling; Event based modeling; Two-stroke engines; Crankcase; Fuel dynamics; Wall wetting; Gas mixing;

    Abstract : For any crankcase scavenged two-stroke engine, the fuel dynamics is not easily predicted. This is due to the fact that the fuel has to pass the crankcase volume before it enters the combustion chamber. READ MORE
