1. An investigation into ocean thermodynamics and water-mass transformation
Sammanfattning : This thesis presents oceanic budgets of potential temperature, salinity and buoyancy as well as a novel way of diagnosing water-mass transformation in salinity-temperature space. The buoyancy of seawater is given by a nonlinear function of temperature, salinity and pressure and much of the work in this thesis revolves around how fluxes of heat and salinity influence the buoyancy of seawater through these nonlinearities.

2. Arctic clouds - interactions with radiation and thermodynamic structure
Sammanfattning : Clouds play in important role in the climate system through their interaction with radiation. Globally, clouds tend to cool the Earth by reflecting solar radiation and shading the surface. LÄS MER
3. Fundamental properties of neutrinos: masses and mixings
Sammanfattning : Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. LÄS MER
4. Novel approaches in modeling of soil carbon : Upscaling theories and energetics
Sammanfattning : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

5. On the Use of Laser-Induced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines
Sammanfattning : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. LÄS MER
