1. 1. 4D in city transformations : systems, processes and actors

   Författare :Tim Johansson; Timo Hartmann; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggproduktion; Construction Engineering and Management;

   Sammanfattning : The city of Kiruna is facing the challenge of relocating a large proportion of the existing city centre as a consequence of the subsidence caused by underground mining activities. This relocation includes urban residential areas, industrial areas, offices and spaces such as parks and infrastructure. LÄS MER

3. 2. Gene Regulatory Networks: Dynamics and Stability

   Författare :Carl Troein; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems; control; Datalogi; numerisk analys; system; kontroll; Computer science; numerical analysis; Fysik; biomathematics biometrics; Bioinformatik; medicinsk informatik; biomatematik; Physics; medical informatics; transcriptional regulation; gene regulatory networks; Bioinformatics; signaling pathway profiling; stem cell regulation; metabolic pathway; fitness; nested canalyzing rules; Kauffman networks; random Boolean networks; Fysicumarkivet:2007:Troein;

   Sammanfattning : Life as we know it is based on cells that use proteins and RNA to carry out metabolism, self-replication, and other essential tasks. The genes that code for these molecules are encoded in DNA, and through the processes of transcription and translation the cell expresses its genes. LÄS MER

4. 3. Population regulatory processes in the Baltic salmon (Salmo salar)

   Författare :Stefan Skoglund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Knowledge and understanding of population regulation is the foundation that allows for sustainable harvest of natural populations. In this thesis, I explore potential sources of bias in stock recruitment relationships resulting from potential spawning behaviours, and investigate alternative methods that can be used in order to evaluate population regulatory processes and improve estimates of stock-assessments of the Atlantic salmon (Salmo salar) in the Baltic Sea.

5. 4. Studies of Cellular Regulatory Mechanisms : from Genetic Switches to Cell Migration

   Författare :Maria Werner; Erik Aurell; Ulrich Gerland; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik;

   Sammanfattning : Cellular behaviour depends ultimately on the transcription of genes. If we know how transcription is controlled we have a better chance of understanding cellular processes. This thesis presents six studies, all concerning cellular regulatory mechanisms. One study is purely experimental and five are computational studies. LÄS MER

7. 5. Regulatory mechanisms of amino acid-induced signaling in Saccharomyces cerevisiae

   Författare :Deike J. Omnus; Per O. Ljungdahl; Claudio De Virgilio; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; regulatory mechanisms; nutrient sensing; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

   Sammanfattning : This thesis describes studies aimed at elucidating the molecular mechanisms that regulate the SPS (Ssy1-Ptr3-Ssy5) signal transduction pathway in the yeast Saccharomyces cerevisiae. This pathway is induced by extracellular amino acids and facilitates their uptake. LÄS MER
