6. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany
University essay from Stockholms universitet/Institutionen för naturgeografiAbstract : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

7. Thermochemistry modelling applied to activated sludge process: Feasibility assessment
University essay from KTH/ProteinvetenskapAbstract : Aktivt slam är en biologisk process som används i stor utsträckning för rening av avloppsvatten, där bakterier som odlas under luftiga förhållanden avlägsnar organiska ämnen och näringsämnen från förorenat vatten. För industriell verksamhet modelleras denna process för att representera och förutsäga biologiska fenomen. READ MORE

8. Reindeer decrease soil carbon stocks and deplete labile soil carbon
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.

9. Microbial Carbonisation and its potential for on-farm composting : exploring reductive composting as an approach for regenerative agriculture
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : The search for agronomic solutions to the decline of soil health, open-ended nutrient cycles and greenhouse gas (GHG) emissions from agriculture, against the background of impending climate change, were motivations for this thesis. A composting trial on a Swedish farm was designed to find answers to the overarching research question of how feasible and climate-friendly on-farm composting using Microbial Carbonisation (MC) is, compared to conventional windrow composting (CC).

10. Bearbetningsmetoders påverkan på markorganismers aktivitet i jorden : i perenna odlingar samt i odlingssystem med mellangrödor
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : Klimatförändringarna, som både påverkat och påverkar vår planet, kräver att mänskliga aktiviteter förändras till mer resurssnåla och systemeffektiva processer. I dessa processer bör markens bördighet vara det centrala, eftersom en bördig mark kan generera stabila skördar och bidra till en långsiktigt hållbar matförsörjning. READ MORE
