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

   Sammanfattning : 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.

3. 12. Expositiones sequentiarum : Medieval Sequence Commentaries and Prologues. Editions with Introductions

   Författare :Erika Kihlman; Gunilla Iversen; Susan Boynton; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Medieval Latin; sequence commentaries; prologue; Alan of Lille; Pseudo-Dionysius; John Scottus Eriugena; Gregory the Great; the ‘Aristotelian tradition’; angels; angelical hierarchy; glosses; etymology; Ad celebres rex; Latin language; Latin;

   Sammanfattning : The sequence commentary emerged as a new branch of medieval commentary literature in the twelfth century. The sequence itself, sung in the Roman Mass, was a hugely influential genre—several thousands of sequence texts are known today—but the fact that the Middle Ages also produced commentaries on this liturgical poetry has been hitherto practically unknown and very few commentary texts have been edited.

4. 13. Thermodynamics of Protein Folding and Design

   Författare :Erik Sandelin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;

   Sammanfattning : The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. LÄS MER

5. 14. Genetic organization of encapsulated and non-encapsulated Haemophilus influenzae strains. Analysis of the glpTQ and 23S rRNA operons

   Författare :Xin-Ming Song; Malmö Klinisk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; intervening sequence; 23S rRNA; transcription; DNA sequence; glpT; Haemophilus influenzae; glpQ; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Encapsulated Haemophilus influenzae type b (Hib) and non-encapsulated H. influenzae (NTHi) are important pathogens causing invasive and mucosal infections in children. A 42 kDa surface-exposed lipoprotein, protein D, has been found to be a potential virulence factor of NTHi. LÄS MER

7. 15. Decoding Heparan Sulfate

   Författare :Johan Kreuger; John T. Gallager; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Heparan sulfate; fibroblast growth factor; receptor; endostatin; angiogenesis; interaction; sequence; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

   Sammanfattning : Heparan sulfate (HS) is a polysaccharide of glycosaminoglycan type composed of alternating hexuronic acid [either glucuronic acid (GlcA) or iduronic acid (IdoA)] and glucosamine (GlcN) units that can be sulfated in various positions. HS binds to a large number of proteins and these interactions promote many biological processes, including cell adhesion and growth factor signaling. LÄS MER
