  1. 21. Hemocytes and neural injury in freshwater crayfish : Does the melanization reaction matter?

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Amanda Gustafsson; [2022]
    Nyckelord :Melanization; neural injury; freshwater crayfish; Melanisering; nervskada; sötvattenskräfta;

    Sammanfattning : Neurogenesis primarily occurs during embryonic development in decapod crustaceans, ending when the embryonic precursor cells die. However, areas in the central olfactory pathway are exceptions to this. Here, neurons are produced throughout the animal’s life from precursor cells in the neurogenic niche. LÄS MER

  3. 22. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Andras Szanthoffer; [2022]
    Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER

  4. 23. Assessing the effectiveness of siloxane-based flame retardants

    Master-uppsats, KTH/Kemiteknik

    Författare :Josefin Eklund Wallin; [2022]
    Nyckelord :Polyhderal oligomeric silsesquioxane; POSS; PVC; TGA DSC; DSC; thermal properties;

    Sammanfattning : Polyedrisk oligomer silsesquioxane (POSS) är molekyler som har en inorganisk ryggrad med organiska grupper fa ̈sta utan på. Själva kåren har en bur liknande form och har en hög termisk stabilitet tack vare kisel (Si) och syre (O) som den består av. LÄS MER

  5. 24. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :David Llorens Rauret; [2022]
    Nyckelord :Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Sammanfattning : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. LÄS MER

  7. 25. How About Running on Mars ? Influence of Sensory Coherence on the Running Pattern and on Spatial Perception in Simulated Reduced Gravity

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Marie Keime; [2022]
    Nyckelord :Adaptation; Gravity; Locomotion; Sensory factors; Spatial perception; Unweighting.; Rörelse; Gravitation; Anpassning; Avvägning; Sensoriska faktorer; Rumslig uppfattning.;

    Sammanfattning : Motor control, including locomotion, strongly depends on the gravitational field. Recent developments like lower-body positive pressure treadmills (LBPPTs) have enabled Earth- based studies on the effects of reduced body weight (BW) on walking and running. Yet, the observed adaptations to simulated hypogravity are not optimal. LÄS MER
