Sammanfattning : Background Adipose tissue (AT) is not only a store of energy but an endocrine organ with capacity to produce and release proinflammatory mediators into the circulation. Obesity is an inflammatory disease, with increased circulating levels of interleukin (IL)-6, due to synthesis in AT. LÄS MER
Sammanfattning : Water vapour and clouds in the upper troposphere have strong influence on the Earth's climate system. The present uncertainties regarding the distribution and feedback mechanisms of water to a changing climate are today among the greatest limitations for accurate climate predictions. LÄS MER
Sammanfattning : High-temperature electronics find use in extreme environments, like data logging in downhole drilling for geothermal energy production, inside of high-temperature turbines, industrial gas sensors and space electronics. The simplest systems use a sensor and a transmitter, but more advance electronic systems would additionally require a microcontroller with memory. LÄS MER
Sammanfattning : Humidity and clouds in the upper troposphere are important factors for the Earth's radiative balance.Consequently a weakness in global climate models is that very little is known about the concentration of water vapour or the distribution and properties of clouds in this altitude region.

5. On the use of traffic flows for improved transportation systems : Mathematical modeling and applications
Sammanfattning : This thesis concerns the mathematical modeling of transportation systems for improved decision support and analysis of transportation-related problems. The main purpose of this thesis is to develop and evaluate models and methods that exploit link flows. LÄS MER
