  1. 21. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Hanna Ravry; [2022]
    Keywords : phosphorus; sediment; oligotrophication;

    Abstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE

    Abstract : The sediment Core SWERUS-L2-2-PC1 (2PC) retrieved from the Chukchi Sea, Arctic Ocean sits in an oceanographically dynamic location at the Arctic-Pacific Ocean gateway. The 8.3 m-long core was retrieved in Herald Canyon at the marginal ice zone at 57 m depth. READ MORE

  4. 23. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Author : Emma Beskow; [2022]
    Keywords : GNSS; GPS; Jamming; Beamforming; Adaptive antenna arrays; Frequency response distortions;

    Abstract : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference.

  5. 24. Delusions of body ownership : A systematic review of somatoparaphrenia

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Robin Johansson; [2022]
    Keywords : Somatoparaphrenia; mri; ct; ownership;

    Abstract : Somatoparaphrenia (SP) is a disorder where patients deny ownership of their limb and display delusional ideas regarding it. In a review by Vallar and Ronchi (2009), they systematically reviewed the SP literature, and made several conclusions regarding the neural correlates of SP. READ MORE

  6. 25. Recurring Slope Lineae on the Northern Hemisphere of Mars: an investigation into the new candidate sites

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Andreas Eriksson; [2021-04-06]
    Keywords : Recurring Slope Lineae; RSL; Mars; HiRISE; Candidate sites; GIS; Northern hemisphere;

    Abstract : Recurring Slope Lineae (RSL), are dark markings found on slopes with a steepness of 25°- 45°. Their width is between 0.5-5 m but they can become hundreds of meters long. They grow incrementally during warm seasons; fade during cold seasons and appear again the following Mars year. READ MORE
