  1. 1. Platsens betydelse för växtnäringsläckage från jordbruksmark i Sverige

    University essay from SLU/Dept. of Soil and Environment

    Author : Frida Lundell; [2023]
    Keywords : kväve- och fosforutlakning; rumslig variation; långtidsövervakning;

    Abstract : Växtnäringsläckage av kväve (N) och fosfor (P) från jordbruksmark tillför näringsämnen till hav och vattendrag. Det är viktigt att minska transporten av N och P av flera anledningar, då det bland annat är en stor bidragande faktor till övergödning. READ MORE

  3. 2. Analysis of pervasive climate risks to global rice production at the subnational level

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Qian Mei; [2023]
    Keywords : ;

    Abstract : Rice is a vital crop and main source of calories for half the global population, particularly in the GlobalSouth. Despite increasing demand for rice, climate change, urbanisation, and land use development arethreatening rice production and therefore food security. READ MORE

  4. 3. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

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

    Author : Anna Lackner; [2022]
    Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

    Abstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

  5. 4. Measurement of timescales of cortical neuronal activity in behaving mice

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sasa Lekic; [2021]
    Keywords : Neural activity; prefrontal cortex; visual cortex; Timescale; Spike trains; Functional hierarchy; Neural aktivitet; PFC; Timescale; Spike train; Funktionell hierarki;

    Abstract : Electrical activity is omnipresent throughout the brain, and it varies dependant on the brain region. Areal hierarchy has been suggested to be one of the main principles of the organization of the brain, but there is not a lot of evidence available related to the specialization of the brain’s regions in the temporal domain, that is, how the activity evolves over time.

  6. 5. Dynamics of streamflow and stream chemistry in a Swiss pre-Alpine headwater catchment : A fine scale investigation of flow occurrence and electrical conductivity in the temporary streams in the lower Studibach catchment

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elise Baumann; Hanna Berglund; [2021]
    Keywords : Temporary Streams; Pre-Alpine Catchment; Streamflow; Stream Chemistry; Fine Scale Investigation; Electrical-conductivity; Stream Mapping; Temporära bäckar; Pre-Alpina avrinningsområden; Bäckflöden; Vattenkemi; Finskalig undersökning; Elektrisk konduktivitet; Bäck-kartering;

    Abstract : Temporary streams and their dynamics have often been largely overseen in hydrological research and there is relatively little knowledge about how the occurrence of flow in these streams varies temporally and spatially. Temporary streams are important from a hydro- logical perspective because they affect water quantity and quality in downstream peren- nial reaches, and from an ecological perspective because they provide habitat to unique species.
