1. 1. Invasive plant species in southwest Sweden: Evaluation methods of removal by empirical study and literature review

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Carl-Johan Dekker; [2023-08-07]
   Keywords : Invasive alien species; management; nature conservation; biodiversity;

   Abstract : Invasive alien species (IAS), are one of the five biggest threats to biodiversity worldwide. An instrument for biodiversity protection in Sweden is the establishment and management of nature reserves. The goal of nature reserves is to protect valuable nature and rare species to preserve biodiversity. READ MORE

3. 2. Formulation and characterisation of novel edible-packaging for fruits and vegetables

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

   Author : Lola Sutton; Katerina Papa; [2023]
   Keywords : algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

   Abstract : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. READ MORE

4. 3. Effects of Energy Performance Improving Measures on a 1990's Brick House in Southern Czech Republic : Computer Simulations using IDA-ICE

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Vaclav Panek; [2023]
   Keywords : Final energy demand; Primary energy demand; Energy performance; Refurbishment; Single-family house; Space heating;

   Abstract : The residential sector was responsible for 25% of the Final Energy Demand (FED) in the European Union in 2015. Countries in Central and Eastern Europe such as the Czech Republic are particularly concerned with ensuring security of supply at the lowest possible cost in recent years. READ MORE

5. 4. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

6. 5. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

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

   Author : Gioele Daka; [2023]
   Keywords : Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

   Abstract : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. READ MORE
