  1. 1. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Arvid Söderlund; [2023]
    Keywords : Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

    Abstract : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

  3. 2. Methods to study device induced aggregation of proteins

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Marie Therese von Wowern; [2023]
    Keywords : protein formulation; protein aggregation; insulin; silicone oil; syringe; shear stress; subvisible particle; size exclusion chromatography; flow imaging microscopy; pharmaceutical technology; Technology and Engineering;

    Abstract : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. READ MORE

  4. 3. Effect of DNAJB6 on α-synuclein amyloid fibril aggregation and dis-aggregation

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Josef Getachew; [2023]
    Keywords : α-synuclein; alpha-synuclein; chaperones; DNAJB6; the unhappy chaperone; parkinsons disease; biophysical chemistry; biochemistry; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Amyloid proteins are a group of proteins with the ability to form large fibrillar aggregates, identifiable by their cross-β core structure. These aggregates are linked to several different neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease and due to the growing rate of people diagnosed, there is a need to combat these diseases.

  5. 4. Perception of variety in forests in relation to reducing polygon count : Exploring human perception in computer graphics and computer graphics education

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Amani Najimudeen; [2023]
    Keywords : aggregates; perception; forests; computer graphics education; aggregat; mänsklig uppfattning; skogar; datorgrafikundervisning;

    Abstract : By taking human perception into account in computer graphics, time and processing power may be utilised more efficiently when modelling and rendering scenes. Exploring possibilities for reducing the complexity of forest scenes is particularly interesting because of the geometric complexity of trees, the effects of which are compounded by dense, large-scale forests.

  6. 5. Aggregation mechanisms of proteins in liquid formulations

    University essay from KTH/Kemi

    Author : Amanda Hamrin; [2022]
    Keywords : Protein aggregering; seedingmekanism; dynamic light scattering; differential scanning calorimetry; Somatropin; monoklonal antikropp; Protein aggregation; seeding mechanism; dynamic light scattering; differential scanning calorimetry; somatropin; monoclonal antibody;

    Abstract : Biologiska läkemedel har under det senaste århundradet utökats, och under de senaste 25 åren så har proportionen av godkända biologiska läkemedel har ökat för behandlingen av sjukdomar, vaccin, och diagnostik. Det finns flera olika mekanismer för protein aggregering, och en av dessa är seeding, vilket innebär aggregering inducerat av tillsatta aggregat eller förekomsten av strukturförändringar i proteinet.
