  1. 1. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Keywords : hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Abstract : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. READ MORE

  2. 2. Evaluation of the forest composition in browsed Scots pine plantations

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Carl Noyce; [2022]
    Keywords : browsing damage; forest owners; mera tall; moose; pine regeneration; Södra;

    Abstract : Since the early 2000s browsing damage to Scots pine (Pinus Sylvestris) in the Götaland region of Sweden has been consistently estimated to be 15% per year, peaking at around 25% between 2009-2016, the highest of any region in the country. The Swedish Forest Agency has set a goal of achieving pine damage levels below 5% on average in the long-term, even if higher levels can be accepted in an individual year. READ MORE

  3. 3. Produktionsjämförelse av genetiskt förädlad vårtbjörk med finskt och svenskt ursprung

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Pelle Eriksson; Carl Åhlund; [2020]
    Keywords : Betula pendula; Finland; plusträd; kvalitet; tillväxt;

    Abstract : Genetisk förädling av ett trädslag innebär förbättring av tillväxtegenskaper och förbättring av kvalitén, det kan även leda till bättre anpassning till miljön vilket är viktigt då klimatet ändras. I Sverige har förädlingen av barrträd lett till högre avkastning av skogsproduktion, men för björk finns endast förädlat material från ett första generationens plantage i södra Sverige. READ MORE

  4. 4. PID tuning with Ant Colony Optimization (ACO) : A framework for a step response based tuning algorithm

    University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Author : Carl Johan Björk; [2018]
    Keywords : PID; self-tuning; control system; building automation; ant colony optimization; neural networks; open-loop; closed-loop; step response.; PID; självtrimning; reglersystem; byggnadsautomation; myrkolonioptimering; neurala nätverk; öppen slinga; sluten slinga; stegsvar.;

    Abstract : The building automation industry lacks an affordable, simple, solution for autonomous PID controller tuning when overhead variables fluctuate. In this project, requested by Jitea AB, a solution was developed, utilising step response process modelling, numerical integration of first order differential equations, and Ant Colony Optimization (ACO).

  5. 5. Power output at different loads using accommodating resistance in the bench press exercise

    University essay from Biomekanik och biomedicin

    Author : Carl Raask; Oscar Björk; [2013]
    Keywords : ;

    Abstract : Introduction: To date, there are no definitive guidelines as for how to optimally train for power production. Previously conducted studies are lacking consensus and have reported conflicting suggestions regarding what loads to use and how to execute the movements. READ MORE
