  2. 1. Surface characterization of the chromium hydroxide and basic calcic deposition layers formed on the steel cathode in the chlorate production process

    Author : Annika Ahlberg Tidblad; KTH; []
    Keywords : ;

    Abstract : During technical service, the surface of the steel cathodein the chlorate production process changes with respect tochemical composition and morphology. Deposition of insolublespecies from the electrolyte and corrosion products from thebase metal accumulate and form surface layers that influencethe cathode activity with regards to hydrogen evolution, theprimary reaction, as well as to various parasitic reactions.

  4. 2. Critical Phenomena and Exchange Coupling in Magnetic Heterostructures

    Author : Martina Ahlberg; Gabriella Andersson; Björgvin Hjörvarsson; Steve Bramwell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phase transitions; critical behavior; 2D XY model; MOKE; magnetic thin films and superlattices; amorphous multilayers; magnetic proximity effects; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The continuous phase transition in thin magnetic films and superlattices has been studied using the magneto-optical Kerr effect (MOKE) and polarized neutron scattering (PNR).  It has been shown that the critical behavior of amorphous thin films belonging to the 2D XY universality class can be described within the same theory as crystalline sample.

  5. 3. Detection and Tracking in Thermal Infrared Imagery

    Author : Amanda Berg; Michael Felsberg; Jörgen Ahlberg; Thomas B. Moeslund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Abstract : Thermal cameras have historically been of interest mainly for military applications. Increasing image quality and resolution combined with decreasing price and size during recent years have, however, opened up new application areas. They are now widely used for civilian applications, e.g. READ MORE

  6. 4. Who ate whom? Paleoecology revealed through synchrotron microtomography of coprolites (fossil feces)

    Author : Martin Qvarnström; Živilė Žigaitė; Grzegorz Niedźwiedzki; Per Ahlberg; Karen Chin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coprolites; paleoecology; synchrotron microtomography; taphonomy; Triassic; Biologi; Biology;

    Abstract : Fossil droppings, known as coprolites, are being increasingly recognized as a valuable source of paleoecological information with special regard to diets, parasitism, and physiology of extinct taxa. Here, it is suggested that the excellent preservation and amount of inclusions in the coprolites (e.g. READ MORE
