   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; JUICE mission; positive ions; negative ions; electrons; time-of-flight; time-of-arrival; PEP; JDC; CEM; channel electron multiplier; pressure; instrument development; calibration; TOF; TOA; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

   Sammanfattning : This dissertation covers the development and calibration of the Jovian plasma Dynamics and Composition analyzer (JDC). JDC is together with five other sensors a part of the Particle Environment Package (PEP), one of the payloads of the European Space Agency's JUpiter ICy moons Explorer (JUICE) mission. LÄS MER

3. 2. Structures in complex systems : Playing dice with networks and books

   Författare :Sebastian Bernhardsson; Petter Minnhagen; Stefan Bornholdt; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; networks; statistical physics; biological networks; quantitative linguistics; word frequencies.; Physics; Fysik;

   Sammanfattning : Complex systems are neither perfectly regular nor completely random. They consist of a multitude of players who, in many cases, playtogether in a way that makes their combined strength greater than the sum of their individual achievements. LÄS MER

4. 3. Understanding the application of knowledge management to the safety critical facilities

   Författare :Elena Ilina; Håkan Sundquist; Yanko Yanev; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nuclear physics; Kärnfysik; Building engineering; Byggnadsteknik;

   Sammanfattning : Challenges to the operating nuclear power plants and transport infrastructures are outlined. It is concluded that most aggravating factors are related to knowledge. Thus, of necessity, effective knowledge management is required. LÄS MER

5. 4. The Biophysics of Na+,K+-ATPase in neuronal health and disease

   Författare :Evgeny E. Akkuratov; Hjalmar Brismar; Anita Aperia; Stefan Wennmalm; Poul Nissen; KTH; []

   Sammanfattning : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. LÄS MER

7. 5. Chemical and Morphological Characterisation of Aerosol Particles in the Tropopause Region

   Författare :Hung Nguyen Ngoc; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CARIBIC; Physics; Singel particle analysis TEM and EFTEM; Carbon and Sulphur; Light element analysis; Aerosol sampler; Chemical Characterisation; Aerosol in the Tropopause Region; Nuclear physics; Technological sciences; Fysik; Teknik; Kärnfysik; Fysicumarkivet A:000;

   Sammanfattning : The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. LÄS MER
