1. 1. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

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

   Author : Pranay Kumar Parsi; [2023]
   Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

3. 2. Forecast-based AI Decisions for Winter Road Maintenance

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Johan Alfredéen; [2022]
   Keywords : ;

   Abstract : In countries with freezing temperatures, proper road maintenance is an important intervention to reduce traffic accidents and fatalities and improves road passability. While de-icing using road salt can be an effective intervention, it may also lead to harmful side effects such as damage to vehicles, groundwater contamination and plant stress. READ MORE

4. 3. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

   University essay from SLU/Dept. of Clinical Sciences

   Author : Lea Enenkelová; [2021]
   Keywords : sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

   Abstract : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

5. 4. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

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

   Author : Oscar de Kuijer; [2021]
   Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

6. 5. Effects of Vacuum Impregnation with Various Substances in Combination with Pulsed Electric Field to Improve the Freezing Tolerance of Arugula Leaves

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

   Author : George Lukhava; [2021]
   Keywords : Food Engineering; Food Preservation; Pulsed Electric Fields; PEF; Vacuum Impregnation; VI; Arugula; Cryoptrotectant; Glycerol; Secondary Metabolites; Folic Acid; Folate; Folacin; Vitamin B1; Thiamine; Thiamin; Agriculture and Food Sciences;

   Abstract : As of 2020 an estimated number of 821 million people across the world are undernourished and that figure is expected to grow by 2 billion before the end of 2050 (United Nations Sustainable Development 2020). Despite this, every year over 1/3 of food produced globally is disposed of without consumption (Global Panel on Agriculture and Food Systems for Nutrition 2018), and the actual number might be much higher.
