  1. 1. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  2. 2. Phosphorus reduction in wastewater using microalgae with different phosphorus starvation periods

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Fredrika Murby; [2021]
    Nyckelord :;

    Sammanfattning : Anthropogenic induced nutrients in the Baltic Sea have led to 97% of it being eutrophic. Phosphorus is regarded the main regulating nutrient, and nearly 25% of the nutrients coming to the Baltic Sea originate from wastewater treatment plants. LÄS MER

  3. 3. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ainahu Abdul Hamid; [2021]
    Nyckelord :Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Sammanfattning : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. LÄS MER

  4. 4. Characterization and optimization of Rhodosporidium toruloides for production of lipids

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Niharika Singh; [2021]
    Nyckelord :chemical engineering; oily yeasts; lipids; nitrogen limitation; Technology and Engineering;

    Sammanfattning : Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. LÄS MER

  5. 5. Produktion av polyhydroxyalkanoater (PHA) av avloppsvatten från massa och pappersindustri : En studie kring bakteriernas förmåga att ackumulera PHA beroende på sammansättning av karboxylsyror

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jimmy Augustsson; Jonathan Högfeldt; [2020]
    Nyckelord :Bioplastics; Mixed bacterial culture; HTC; VFA; Bioplast; mixad bakteriekultur; HTC; VFA;

    Sammanfattning : Since the beginning of the 20th century plastic has been a widely used material, which has resulted in large quantities of plastic being produced in the last century. The plastics of today are mainly produced from fossil raw materials, which gives it a high climate impact. LÄS MER
