  2. 1. CALIBRATION OF CHROMATOGRAPHY MODELS

    Author : Patrik Persson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; film mass transfer resistance; Kemiteknik och kemisk teknologi; sorption kinetics; external volume; monolithic bed; shallow bed; packed bed; capillary model; detailed model; computer simulation; parameter estimation; diffusion; model calibration; Chromatography; modelling; proteins; Chemical technology and engineering;

    Abstract : AbstractThis thesis is devoted to calibration of mathematical chromatography models. Chromatography models include unknown parameters that must be determined before the models can be applied to optimization or scale-up of a chromatography process. READ MORE

  4. 2. Spring dynamics in shallow lakes: the role of plankton, fish and macrophytes in a changing climate

    Author : Alice Nicolle; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zooplankton; spring; 0 fish; macrophytes; phenology; climate change; shallow lakes;

    Abstract : Shallow lakes such as Lake Krankesjön are characterized by their extended littoral zones, usually covered by submersed and emergent vegetation. In paper 1, I investigated the relationship between turbidity and macrophyte growth (Chara spp. READ MORE

  5. 3. Compositional variability of settling organic particles in non-tidal coastal and shelf enviroments

    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

  6. 4. Three Dimensional Hydro-Morphological Modeling of Tigris River

    Author : Ammar Ali; Robert William Duck; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The River Tigris is a major river in Iraq. It divides Baghdad, the capital of Iraq, in two parts. The reach of the river within Baghdad is about 60 km long. The climate change within the region and the construction of hydraulic structures upstream of Baghdad has reduced the water discharge of the river by 44%. READ MORE

  7. 5. Palaeoenvironments, palaeoecology and palaeobiogeography of Late Cretaceous (Campanian) faunas from the Kristianstad Basin, southern Sweden, with applications for science education

    Author : Elisabeth Einarsson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; palaeoenvironments; palaeoecology; palaeobiogeography; Campanian; Kristianstad Basin; Teaching and Learning;

    Abstract : This thesis is thematically divided into two sections: Part1 presents studies related to the palaeoenvironments,palaeoecology and palaeobiogeography of the LateCretaceous (Campanian) faunas from the KristianstadBasin of southern Sweden; Part 2 reports on applicationsof palaeontological research for science education inschools.Part 1 was based on personally conducted fieldworkand biostratigraphical analysis at various Santonian-Campanian localities throughout Skåne.
