1. 16. Frost prediction in heat exchangers : The influence of relative humidity and outdoor temperature on frost formation in plate heat exchangers

   University essay from KTH/Betongbyggnad

   Author : Emin Osmic; [2022]
   Keywords : ;

   Abstract : Frost in Mechanical Ventilation with Heat Recovery (MVHR) often occurs when indoor air is humid and outdoor air is cold. Warm and humid air from the rooms condensates or sublimates when it becomes cold enough, causing frost to grow in the heat exchanger channels. READ MORE

3. 17. Hur påverkar mekaniskt snytbaggeskydd, markberedning, plantstorlek och plantgödsling granplantors överlevnad och tillväxt?

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

   Author : Johanna Abrahamsson; Jessica Wallgren; [2022]
   Keywords : mekaniskt snytbaggeskydd; plantstorlek; markberedning; plantgödsling; föryngringsåtgärder; vitalitet;

   Abstract : Reforestation of land entails both costs and uncertainties. Risk of pine weevil infestation, competition from other vegetation, frost and insufficient nutrient supply are some examples. READ MORE

4. 18. Effects of cover crops on nitrous oxide (N2O) emissions in cereal cropping

   University essay from SLU/Dept. of Ecology

   Author : Khadija Aziz; [2022]
   Keywords : cover crops; nitrous oxide; C sequestration; greenhouse gases; off-season emissions; freeze-thaw cycles;

   Abstract : More than 60% of anthropogenic nitrous oxide (N2O) emissions are attributed to agricultural activities. N2O production in soils highly depends on the N availability along with other factors such as soil moisture content, which provide suitable conditions for nitrification and denitrification.
