  2. 1. Cyclins on the move : a time and a place for cyclin A2 and cyclin B1 in the human cell cycle

    Author : Helena Silva Cascales; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The ultimate aim of the cell cycle is to create an identical daughter cell. Therefore, correct progression through the different phases of the cell cycle is crucial to ensure faithful cell division. READ MORE

  4. 2. Design of High Linearity MMIC Power Amplifiers for Space Applications

    Author : Oliver Silva Barrera; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pHEMT; GaAs; reliability; Power amplifier; non-linear modeling; Junction temperature; C-Band; Infrared measurements;

    Abstract : The high linearity performance in satellite transmitters is receiving increasing attention due to the demands of higher data rates in satellite communication links. During the last decade, digital communication links in satellite system have been replacing the previous analog links increasing the channel efficiency by allocating multiple carriers in the transponder bandwidth.

  5. 3. Mechanisms of inter-organ crosstalk mediated by tryptophan metabolism

    Author : Paula Sofia Valente da Silva; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Physical exercise and nutrition balance the “energy in-energy out” equilibrium that keeps the system at a dynamic homeostasis, energetically speaking. However, this is a simplistic vision of a dynamic system that is in a constant fine-tuning of all of its parts. READ MORE

  6. 4. Mast cells in chronic inflammatory diseases : new insights in mast cell function and phenotype

    Author : Ricardo Filipe Da Silva Carvalho; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mast cells are multifunctional cells that play important roles in health and disease. They are long lived cells with the capacity to be activated several times. Upon activation mast cells release a huge array of mediators. The nature of the mediators released is dependent on the stimuli. READ MORE

  7. 5. Chloride Induced Corrosion of Reinforcement Steel in Concrete - Threshold Values and Ion Distributions at the Concrete-Steel Interface

    Author : Nelson Dias Ferreira Da Silva; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LA-ICP-MS; pitting corrosion; chloride threshold values; concrete-steel interface;

    Abstract : The chloride threshold value (Cth), or critical chloride content, is defined as the chloride concentration at the depth of the reinforcement, which initiates the depassivation of steel in concrete. However, very limited information is available regarding the chloride distributions at the interface with the steel. READ MORE
