1. 26. Global regulatory factors that impact metabolic and lifestyle choices in Pseudomonas putida

   Författare :Lisa Wirebrand; Victoria Shingler; Matthew Francis; Carlos Balsalobre; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas putida; c-di-GMP; motility; ppGpp; DksA; biofilm dispersal; transcriptional and translational regulation; dmp-system; phenol catabolism; carbon repression control; plasmid stability;

   Sammanfattning : Pseudomonas putida strains have a broad metabolic capacity and are innately resistant to many harmful substances – properties that make them of interest for a number of industrial and biotechnological application. They can rapidly adapt to changes in physico-chemical parameters in the soil and water environments they naturally inhabit. LÄS MER

   Sammanfattning : Apoptosis is one of the most common types of cell death. Under physiological conditions, it plays an essential role in removal of damaged and potentially harmful cells. Excessive apoptosis has however been linked to a number of diseases including proteinuric kidney disease and DKD, and is believed to enhance the disease progression. LÄS MER

4. 28. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

   Författare :Anna Nordén; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Hermaphrodite; Inter-sexual genetic correlation; Quantitative genetics; Macrostomum lignano; Experimental evolution; Sexual conflict;

   Sammanfattning : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. LÄS MER

5. 29. Avian MHC : Characterization and expression patterns of classical and non-classical MHC-I genes

   Författare :Anna Drews; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MCH class I; Classical genes; Non-classical genes; Expression; Passerine birds;

   Sammanfattning : The function of the vertebrate immune system is to enable recognition and elimination of microorganisms that can cause harm (pathogens). A key component in adaptive immunity is the major histocompatibility complex (MHC) that codes for molecules with antigen presentation function. LÄS MER

7. 30. Cooperative Planning Control and Formation Control of Multi-Agent Systems

   Författare :Alexandros Nikou; Dimos Dimarogonas; Julien Hendrickx; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Cooperative planning control is an active topic of research, with many practical applications including multi-robot systems, transportation, multi-point surveillance and biological systems. The contributions of this thesis lie in the scope of three topics: formation control, time-constrained cooperative planning control and probabilistic control synthesis, all of the them in the framework of multi-agent systems.
