Observed and simulated changes in extreme precipitation and cold surges in China: 1961–2005
(2013-02-01)In the present work, precipitation and temperature related climate extremes are examined, with a focus on Mainland China. The objectives of this study are a) to identify targeted climate extremes and their changes during ... -
Observing and Modeling Precipitation in the Tibetan Plateau region - from large-scale processes to convective storms
(2023-02-20)Climate change in mountain regions has far-reaching societal impacts such as increased risks for natural hazards and water scarcity that may affect billions of people in the downstream regions. Precipitation changes play ... -
Ocean circulation in the Amundsen Sea, West Antarctica
(2017-05-30)The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is ... -
Ocean Climate Variability over Recent Centuries Explored by Modelling the Baltic Sea
(2009-09-03)Natural variability and anthropogenic factors both contribute to changes in the ocean climate of the Baltic Sea. Observations over the past century indicate that changes in environmental settings and ocean climate have ... -
Ocean mixing and polynyas at Maud Rise, Weddell Sea
(2022-04-22)The Weddell Sea Polynya is an intermittent, ice free area in the marginal ice zone with an extent of up to 350 000 km². It was first observed by satellites in the winter seasons of 1974-1976. In 2016 and 2017, an open-ocean ... -
Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes
(2009-05-06)This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamics and finally sea ... -
Okounkov bodies and geodesic rays in Kähler geoemtry
(2012-05-10)This thesis presents three papers dealing with questions in Kähler geometry. In the first paper we construct a transform, called the Chebyshev transform, which maps continuous hermitian metrics on a big line bundle to ... -
Om skogen i Hökensås
(Hantverkslaboratoriet, 2015)Timmer till rekonstruktionen av Södra Råda medeltidskyrka väljs med omsorg för att likna det som användes på 1300-talet. Timmerman Robert Carlsson berättar om det och om skogsbestånd och bonitet i "kyrkskogen" i Hökensås. ... -
On aging and the role of Ubp3 in heterochromatic gene silencing and protein quality control
(2014-09-04)Aging is characterized by a build-up of damage in organisms ranging from protists to multi-cellular species. This damage adversely affects core components such as DNA and proteins which are necessary to sustain life. ... -
On Biogenic Halocarbons in Antarctic Waters
(2013-10-17)Little is known regarding the distribution of naturally produced volatile halogenated organic compounds, halocarbons, in Antarctic waters and the contribution of these waters to the global atmospheric load of halogens. In ... -
On the Control of Nematic Liquid Crystal Alignment
(2013-05-07)Liquid crystal displays (LCDs) are incorporated in a great variety of electronic devices such as laptops, mobile phones, TV sets, etc. The performance of LCDs depends strongly on the alignment of liquid crystal and therefore ... -
On the ecophysiology of Baltic cyanobacteria focusing on bottom-up factors
(2010-11-05)Cyanobacterial blooms in the Baltic Sea are dominated by diazotrophic cyanobacteria, i.e. Aphanizomenon sp. and Nodularia spumigena. The blooms coincide with a stable stratification and the organisms are concentrated to ... -
On the Efficacy and Ecotoxicity of Antifouling Biocides Lethal and Sublethal Effects on Target and Non-target Organisms
(2013-10-23)From an environmental perspective, there is a need to reduce the amount of biocides from antifouling paints in the marine ecosystem as these biocides can exert a negative effect on the marine life. One way to do this is ... -
On the Electrolyte Induced Aggregation of Concentrated Silica Dispersions - An Experimental Investigation Using the Electrospray Technique
(2011-09-08)Gels are weak, solid-like structures that arise when colloidal particles aggregate to form a network of particle clusters. A variety of colloidal systems that are important scientifically as well as in industrial applications ... -
On the exposure assessment of engineered nanoparticles in aquatic environments
(2013-12-10)The socio-economic benefits anticipated with the use and production of nanomaterial and nanoparticles in consumer products are linked to the fulfillment of the requirement for sustainability during the whole material life ... -
On the formation of small molecules by radiative association
(2013-03-05)This thesis is devoted to the theoretical investigation of radiative association, which is one of the processes contributing to formation of molecules in the interstellar medium. The formation of the CN, SiN, SiP and CO ... -
On the generation of Maud Rise polynyas in the Weddell Sea
(2024-04-12)The Weddell Sea is a region prone to the formation of open-ocean polynyas. Open-ocean polynyas are offshore openings of sea ice in the winter season, often accompanied by deep convection. Deep convection allows for the ... -
On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine
(2022-08-25)Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing ... -
On the mathematics of the one-dimensional Hegselmann-Krause model
(2022-01-19)This thesis contains three papers, which all in different ways concern the asymptotics of the Hegselmann-Krause model in opinion dynamics. In this model a set of conformist agents repeatedly and synchronously replace their ... -
