1. 1. Optimization of concrete recipe made with crushed aggregate

   University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Author : Jonathan Lindekrantz; Pontus Axelsson; [2023]
   Keywords : ;

   Abstract : This paper investigate however concrete recipes with a specific type ofcrushed aggregate can be optimized to reduce cement content for concreteand compares it to concrete made with natural fine aggregate. The different aggregate types are sieved, and the particle size distribution curve is made for each one. READ MORE

3. 2. Optical properties of water absorbing textiles for camouflage

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Eveline Örtenberg; [2023]
   Keywords : Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

   Abstract : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. READ MORE

4. 3. 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

5. 4. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Joel Ekström; [2023]
   Keywords : Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

   Abstract : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. READ MORE

6. 5. Biokol som tillsats i vallensilage utfodrat till mjölkraskvigor : inverkan på konsumtionsförmåga, smältbarhet, träckens konsistens och färg, samt djurens renhet

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Ida Milton; [2022]
   Keywords : Biokol; Smältbarhet; Vallensilage; Aktivt kol; Mjölkraskvigor; Konsumtionsförmåga; Träckkonsistens; Färg; Renhet;

   Abstract : Biokol är en produkt som tillverkas av organiskt material eller biomassa i en process som kallas pyrolys, då materialet upphettas i en temperatur från 350 till 1000 ̊C i en syrefri miljö. Biokol är lagringsstabil under lång tid innan den bryts ned och fungerar därför som kolsänka. READ MORE
