  2. 1. Bacterioplankton population dynamics in a changing ocean

    Author : Markus V. Lindh; Jarone Pinhassi; Pierre Galand; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; ecology; bacterioplankton; community composition; diversity; seasonality; biogeography; bimodal; metapopulation; community functioning; climate change; environmental disturbance;

    Abstract : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.

  4. 2. Human Pheromones : Psychological and Neurological Modulation of a Putative Human Pheromone

    Author : Johan N. Lundström; Mats J. Olsson; Noam Sobel; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Pheromones; Odor; Olfaction; Sensitivity; Psychophysiology; Attention; ERP; Mood; Androstadienone; Estratetraenol; Bimodal distribution; Speed of processing; Psykologi; Psychology; Psykologi;

    Abstract : The notion that humans have specialized chemicals used for communication between conspecifics, so-called pheromones, has attracted much attention and discussion. This thesis demonstrates in four separate studies that a human endogenous steroidal compound that is abundant in male sweat, androstadienone, affects women in several ways that differ to that of common odors.

  5. 3. The anode and the electrolyte in the MCFC

    Author : Andreas Bodén; Göran Lindbergh; Carina Lagergren; Takao Watanabe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite electrolytes; electrode kinetics; nickel solubility; porous electrode; reformate; water-gas shift reaction; electrolyte; electrolyte distribution; hydrogen oxidation reaction; ion segregation; mass transport; mathematical modelling; MCFC; molten carbonate fuel cell; Chemical engineering; Kemiteknik;

    Abstract : A goal of the Swedish government is to increase the usage of renewable fuels and biomass-based fuels. Fuel cells, and especially the MCFC, are useful for these types of fuels. The Swedish market may benefit from the MCFC in two ways: increased efficiency of the biofuels and also utilisation of produced heat in district heating. READ MORE

  6. 4. Experimental Studies of Deformation Structures in Stainless Steels using EBSD

    Author : Karin Yvell; Annika Borgenstam; Peter Hedström; Göran Engberg; Johan Moverare; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Austenitic stainless steels; Duplex stainless steel; In situ tensile test; Grain boundaries; Grain rotation; Grain size distribution; Texture; Strain hardening; Structure-property relationship; High strain rate; Wire rod rolling; Roll forming; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Abstract : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. READ MORE

  7. 5. Distributed Photovoltaics, Household Electricity Use and Electric Vehicle Charging : Mathematical Modeling and Case Studies

    Author : Joakim Munkhammar; Joakim Widén; Ewa Wäckelgård; Jesper Rydén; Peter Lund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Photovoltaics; Household Electricity Use; Electric Vehicle Charging; Markov Chain Modeling; Probability Distribution Modeling; Data Analysis; Self-Consumption; Grid Interaction.; Engineering Science; Teknisk fysik;

    Abstract : Technological improvements along with falling prices on photovoltaic (PV) panels and electric vehicles (EVs) suggest that they might become more common in the future. The introduction of distributed PV power production and EV charging has a considerable impact on the power system, in particular at the end-user in the electricity grid. READ MORE
