  2. 1. Aerosol impacts on subtropical low-level clouds: a satellite and modelling perspective

    Author : Alejandro Baró Pérez; Annica M.L. Ekman; Frida A.-M. Bender; Abhay Devasthale; Jens Redemann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aerosol-cloud-radiation interactions; cloud microphysics; biomass burning; stratocumulus to cumulus transition; cloud radiative effect; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Complex interactions between aerosols, clouds, and radiation impact Earth's climate. However, several aspects of these interactions remain uncertain, which has led to extensive research over the last decades. READ MORE

  4. 2. Tailoring of Contacts on Silicon Carbide - Procedures and Mechanisms

    Author : S. A. Perez-Garcia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interfacial reaction; metallic contacts; Silicon carbide; silicides; XPS.;

    Abstract : Silicon carbide (SiC) exhibits very good electrical, thermal, chemical and mechanical properties which make it suitable for the next generation of wide band gap electronic devices, where silicon (Si) cannot be used due to its limitations with respect to the mentioned properties. Nickel (Ni) and Tantalum (Ta) are among the metals used for the contact formation. READ MORE

  6. 4. Metabolic engineering and cultivation strategies for recombinant production of (R)-3-hydroxybutyrate

    Author : Mariel Perez-Zabaleta; Gen Larsson; Antonius J. A. van Maris; Diethard Mattanovich; KTH; []
    Keywords : Escherichia coli; R -3-hydroxybutyrate; nitrogen limitation; nitrogen depletion; lignocellulose; fed batch; acetate; β-ketothiolase; acetoacetyl-CoA reductase; Halomonas boliviensis.; Bioteknologi; Biotechnology;

    Abstract : Metabolic engineering and process engineering are two powerful disciplines to design and improve microbial processes for sustainable production of an extensive number of compounds ranging from chemicals to pharmaceuticals. The aim of this thesis was to synergistically combine these two disciplines to improve the production of a model chemical called (R)-3-hydroxybutyrate (3HB), which is a medium-value product with a stereocenter and two functional groups.

  7. 5. Bright Needles in a Haystack : A Search for Magnetic Monopoles Using the IceCube Neutrino Observatory

    Author : Alexander Burgman; Carlos Pérez de los Heros; Olga Botner; Allan Hallgren; David Milstead; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magnetic monopole; IceCube; astroparticle physics; neutrino telescope; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The IceCube Neutrino Observatory at the geographic South Pole is designed to detect the light produced by the daughter-particles of in-ice neutrino-nucleon interactions, using one cubic kilometer of ice instrumented with more than 5000 optical sensors.Magnetic monopoles are hypothetical particles with non-zero magnetic charge, predicted to exist in many extensions of the Standard Model of particle physics.
