  2. 6. The aquatic microbial food web and occurence of predation-resistant and potentially pathogenic bacteria, such as Francisella tularensis

    Author : Johanna Thelaus; Agneta Andersson; Mats Forsman; Farooq Azam; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacteria; protozoa; ecology; predation; nutrient-availability; microbial food web; model; predation-resistance; Francisella; reservoir; biofilm formation; Freshwater ecology; Limnisk ekologi;

    Abstract : All natural aquatic systems harbour a vast variety of microorganisms. In the aquatic microbial food web, the larger microorganisms (i.e. protozoa) feed on the smaller microorganisms (i. READ MORE

  5. 8. Diagenesis and Reservoir-Quality Evolution of Paralic, Shallow Marine and Fluvio-lacustrine Deposits : Links to Depositional Facies and Sequence Stratigraphy

    Author : Osama Ahmed Hlal; Sadoon Morad; Hans Annersten; J. Marcelo Ketzer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sandstone; Diagenesis; paralic; shallow marine and fluvio-lacustrine; reservoir quality; sequence stratigraphy; Solid earth geology and petrology; Berggrundsgeologi och petrologi;

    Abstract : Linking diagenesis to depositional facies and sequence stratigraphy enables better prediction of spatial and temporal distribution of diagenetic alterations, and thus of evolution of reservoir quality in sandstones. This thesis demonstrates that employing this approach is possible because depositional facies and sequence stratigraphy can provide useful information on parameters controlling the near-surface diagenesis, such as changes in: (i) pore-water chemistry, (ii) residence time of sediments under certain geochemical conditions, (iii) detrital composition and proportion of extra- and intra-basinal grains, and (iv) types and amounts of organic matter.

  6. 9. Impact of Diagenetic Alterations on Reservoir Quality and Heterogeneity of Paralic and Shallow Marine Sandstones : Links to Depositional Facies and Sequence Stratigraphy

    Author : Khalid Al-Ramadan; Sadoon Morad; Luiz Fernando De Ros; Uppsala universitet; []
    Keywords : Bedrock geology; Siliciclastic; Diagenesis; Sequence stratigraphy; Paralic and shallow marine; Heterogeneity; Reservoir quality; Berggrundsgeologi;

    Abstract : This thesis constrains the distribution of diagenetic alterations and their impact on reservoir-quality and heterogeneity evolution pathways in relation to depositional environments and sequence stratigraphy (systems tracts and key sequence stratigraphic surfaces) of four selected paralic and shallow marine siliciclastic successions. Typical eogenetic alterations encountered include the dissolution and kaolinitization of framework silicates, which are closely associated to shoreface facies of forced regressive systems tract (FRWST), lowstand systems tract (LST), upper part of the highstand systems tract (HST), and below the sequence boundary (SB).

  7. 10. Astrocytes : a reservoir for new neurons

    Author : Jens Magnusson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The goal of regenerative medicine is to be able to help the body to replace worn-out cells and tissues. To achieve this goal, one approach being pursued today is to recruit and boost the body’s own mechanisms for cell replacement. READ MORE
