1. Torkstress hos urbana träd i Göteborg: Effekter av låg vattentillgång under torkan 2018
Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : During late spring and most of the summer in the year of 2018 the weather in Sweden was more extreme than normal, with high temperatures and few rainfalls. This resulted in a drought, of which the effects were noticed all over the country. One of the noticeable effects was an earlier leaf abscission from trees. LÄS MER
2. Evaluating aperture shape controller (ASC) in modulated radiation treatments
Master-uppsats,Sammanfattning : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. LÄS MER
3. Estimation of Site-Specific Biomass and Leaf Area Index in a Young Scots pine Stand in Southern Sweden
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Accurate biomass and leaf area index (LAI) estimation are crucial for understanding forest productivity and carbon dynamics. Models are crucial to estimating forest biomass and LAI. This study aimed to estimate site-specific aboveground biomass and LAI in a young Scots pine stand in southern Sweden. LÄS MER
4. Seasonal variation of LAI in Swedish coniferous forest
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Leaf Area Index (LAI) is quantity representing the amount of foliage in the canopy, which makes it an important parameter for analysing terrestrial ecosystems. Traditional methods of measuring LAI were done by analysing hemispherical photographs by hand and were very time consuming, requiring specific weather conditions (Jonckheere et al. 2004). LÄS MER
5. Kvävegödslingens effekter på bladyta och trädkronor i tallbestånd
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Kvävegödsling är en produktionshöjande åtgärd som varit väl etablerad i Sverige genom åren. På grund av gödslingens miljöpåverkan och allmänt högre kunskap om gödsling så är skötselåtgärden inte lika frekvent utnyttjad som den var runt 70-talet. LÄS MER
