1. 26. Pen-rotation scheme for growing pigs : effects on pig aggression and social affiliation

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Moses Agbenyegah Gadri; [2023]
   Keywords : aggressive; affiliative; fighting; littermates; behaviours; reuniting;

   Abstract : This master project aimed to assess if a pen-rotation scheme mitigated the effects of reuniting pigs after temporal separation. Six groups of crossbred (Yorkshire and Hampshire) growing pigs, (8 - 10 littermates per group) aged between 12 – 13 weeks, were video recorded separately in their original home pens for 2 h before a temporal separation to undergo the pen rotation scheme in pairs for 3 days.

3. 27. Utveckling av barrträdsföryngringar markberedda med grävmarkberedning kontra harvning på blockrik skogsmark

   University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

   Author : Svante Brus; [2023]
   Keywords : markberedning; föryngring; död ved; tillväxt; ekonomi;

   Abstract : Markberedning utförs på ungefär 90 % av den föryngrade arealen i Sverige varje år och utförs vanligtvis maskinellt med avsikt att bearbeta marken för att skapa goda förutsättningar för plantetablering.

4. 28. Evaluation of algorithms for accurate micro-doppler effects measurement in FMCW radar

   University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Author : Morgan Agerstig Rosenqvist; [2023]
   Keywords : Radar; FMCW; micro-Doppler; RPM;

   Abstract : Micro-Doppler effects are phenomena that occur because of micro-motion. A micro-motion is either a vibration, rotation, or acceleration which is small relative to the motion of the target. These effects can be used in order to characterize a target through their signature movement. READ MORE

5. 29. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

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

6. 30. Pepita de oro: How AlVelAl is building a regional regenerative agriculture transformation through social innovations

   University essay from Stockholms universitet/Stockholm Resilience Centre

   Author : Elissa Dickson; [2023]
   Keywords : regenerative agriculture; Spain; sustainability transformation; social innovation; adaptive capacity; institutions; drylands;

   Abstract : Regenerative Agriculture (RA) is increasingly promoted as a sustainable agri-food solution. Agronomic studies find that RA practices (e.g. cover crops, reduced tillage, crop rotation, and agroforestry) can regulate soil moisture, sequester atmospheric carbon, enhance biodiversity, and reduce the impacts of droughts and floods.
