Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response
(2014-04-30)Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in ... -
Biogenic Halocarbons in Polar Sea Ice
(2014-04-28)Sea ice is to date a rather poorly investigated part of the cycling of volatile halogenated organic compounds, halocarbons. These compounds are natural sources of reactive iodine and bromine to the atmosphere, and are ... -
Determine the developmental dynamics of primordial follicles in the mouse ovary
(2014-04-15)Ovarian follicles are the basic functional units of the mammalian ovary. Progressive activation of primordial follicles serves as the source of fertilizable ova. In this thesis, by generating the Foxl2-CreERT2 and ... -
Creating and Assessing Multimodal Texts. Negations at the Boundary
(2014-04-09)Digital technologies are becoming increasingly common in educational settings. The availability of such tools facilitates the creation of multimodal texts in which several kinds of expression are combined. In this thesis, ... -
Phenotypic Plasticity and Adaptation Potential to Salinity in Early Life Stages of the Tunicate, Ciona intestinalis spB
(2014-04-08)Species respond to environmental heterogeneity through a variety of mechanisms such as plasticity, genetic adaptation and phenotypic buffering. Determining how gene flow, scale of environmental heterogeneity and trait ... -
Quantum Force in Wigner Space
(2014-04-08)In this thesis, I will present effective methods to study quantum dynamics using trajec- tories. Our methods are based on a method named the Classical Wigner model which starts with a quantum initial condition and generates ... -
Molecular mechanisms optimizing photosynthesis during high light stress in plants
(2014-04-04)ABSTRACT: Oxygenic photosynthesis is the process by which plants, algae and cyanobacteria usesolar energy to convert water and carbon dioxide into molecular oxygen and carbohydrates.Photosynthesis sustains life on Earth ... -
Broadening the perspective on seafood production: Life cycle thinking and fisheries management
(2014-03-28)Decisions made by fisheries managers strongly influence the overall resource use and environmental impacts associated with the seafood product from capture fisheries. These findings come from Life Cycle Assessments (LCA), ... -
Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery
(2014-03-18)The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. ... -
Links between Aging and Proteostasis Decline in Saccharomyces cerevisiae
(2014-03-07)Proteins are continuously synthesized and degraded to meet the demands of the cell. Hence, a proper balance between synthesis, folding, disaggregation and degradation is of essence to ensure cell survival. Disruption of ... -
Vesicle transport in chloroplasts with emphasis on Rab proteins
(2014-02-28)Chloroplasts perform photosynthesis using PSI and PSII during its light-dependent phase. Inside the chloroplast there is a membrane called thylakoid. The thylakoid membranes are an internal system of interconnected membranes ... -
Modeling of radiative processes in organic scintillators
(2014-02-21)This thesis presents the development of a Monte Carlo calibration of a whole body counter (WBC), consisting of four large plastic (organic) scintillators, used for determine the body burden of gamma-emitting radionuclides. ... -

From geography to genes: evolutionary perspectives on salinity tolerance in the brackish water barnacle Balanus improvisus
(2014-02-03)How species respond to changes in their environment is a fundamental question in biology. This has become an increasingly important issue as anthropogenic effects of climate change and biological invasions have major impacts ... -
Late Holocene spatiotemporal hydroclimatic variability over Fennoscandia inferred from tree-rings
(2014-01-27)There is a broad scientific consensus that the global climate is changing, and that human activity is a significant factor contributing to the change. The response of the hydrological cycle to the warming is far reaching, ... -
Electrocatalytic properties of Ni hydroxides with Zn or Co in the Ni matrix
(2014-01-17)The majority of the work in this thesis has been made with the improvement of the systems for electrochemical co-generation of chemicals and electricity in mind. This is an appealing but challenging way of producing chemicals ... -
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 ... -
Teacher Change in relation to Professional Development in Entrepreneurial Learning
(2013-12-02)Abstract Compulsory school teachers’ perceptions and change in relation to Continuing Professional Development (CPD) in entrepreneurial learning are investigated in this thesis. The teacher level focus is based on evidence ... -
New single particle methods for detection and characterization of nanoparticles in environmental samples
(2013-11-28)Nanoparticles (NP) are being used in rapidly increasing quantities which has resulted in concerns about possible harmful effects for health and environment. NP are already undergoing similar risk assessment programs as ... -
Production and Characterisation of Aquaporins and Proton-Translocating Transhydrogenase
(2013-11-15)Dissertation Abstract Water transport in eukaryotic cells is a highly regulated and fine-tuned process. Water channel protein known as aquaporins (AQPs), constitute the main cellular water transport system, preserving ...
