  2. 1. Compositional variability of settling organic particles in non-tidal coastal and shelf enviroments

    Author : Mona Petersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; vertical flux; particulate matter; amino acids; Skagerrak; Limfjorden; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

    Abstract : The coupling between the composition of settling organic particles and near-bed dynamics was studied in non-tidal coastal and shelf environments. Field investigations were made in Skagerrak and Limfjorden between 1990 and 1995. READ MORE

  4. 2. Flow Boiling Heat Transfer in Single Vertical Channels of Small Diameter

    Author : Claudi Martin Callizo; Björn Palm; Predrag Hrnjak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microchannel; heat exchanger; heat transfer; flow boiling; flow patterns; onset of nucleate boiling; dryout; critical heat flux; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract : Microchannel heat exchangers present many advantages, such as reduced size, high thermal efficiency and low fluid inventory; and are increasingly being used for heat transfer in a wide variety of applications including heat pumps, automotive air conditioners and for cooling of electronics.However, the fundamentals of fluid flow and heat transfer in microscalegeometries are not yet fully understood.

  5. 3. The Representation of Atmospheric Boundary Layer Processes in Global Climate Models

    Author : Jenny Lindvall; Gunilla Svensson; Rodrigo Caballero; Andrew R. Brown; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; The atmospheric boundary layer; Global climate models; Diurnal cycle; Flux towers; Diurnal temperature range; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The atmospheric boundary layer is the lowest part of the atmosphere, which is in direct contact with the surface. It is here, in this turbulent layer, that the exchange of heat, moisture and momentum between the surface and the atmosphere takes place. READ MORE

  6. 4. Optical remote sensing of industrial gas emission fluxes

    Author : John Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DOAS; formaldehyde; optical remote sensing; gas emission; absorption spectroscopy; solar occultation; VOC; flux measurement; FTIR;

    Abstract : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have shown that such emissions are often poorly understood, underestimated, and thereby not properly accounted for in emission inventories and regional atmospheric chemistry models, especially for emissions of VOCs.

  7. 5. Applications of ocean transport modelling

    Author : Hanna Corell; Kristofer Döös; Björn Kjerfve; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ocean transport modelling; connectivity; particle-tracking; sediment transport; Forsmark; marine protected areas; MPA; stream functions; heat flux; wind forcing; Carcinus maenas; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The advective motion of seawater governs the transport of almost everything, animate or inanimate, present in the ocean and those lacking the ability to outswim the currents have to follow the flow. This makes modelling of advective ocean transports a powerful tool in various fields of science where a displacement of something over time is studied. READ MORE
