  2. 21. A Gap in the Grid : Attempts to introduce natural gas in Sweden 1967-1991

    Author : Anna Åberg; Arne Kaijser; Per Högselius; Erland Mårald; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; natural gas; energy policy; infrastructure planning; history of technology; Sweden; Northern Europe; risk; project planning; Denmark; Norway; Soviet Union; Germany; energy systems; energy history; fossil fuels;

    Abstract : This thesis follows the process of introducing natural gas in Sweden and the construction of a Northern European gas grid from 1967 to 1991. Natural gas is a relatively unnoticed fuel in Sweden today, but this relative anonymity stands in contrast to an extensive historical activity that has taken place behind the scenes of Swedish energy policy.

  4. 22. Laser Absorption Spectroscopy of Gas in Scattering Media

    Author : Märta Lewander; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; medical diagnosis; gas analysis; absorption spectroscopy; diode laser spectroscopy; light scattering; food-package monitoring; GASMAS;

    Abstract : Absorption spectroscopy constitutes a chemical analysis tool which can be applied to various samples and application fields. This thesis focuses on gas absorption spectroscopy with the means of diode lasers - tunable diode laser absorption spectroscopy, TDLAS. READ MORE

  5. 23. Gas-Phase Protein Structure Under the Computational Microscope : Hydration, Titration, and Temperature

    Author : Erik Marklund; David van der Spoel; Albert Heck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; Physics; Fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. READ MORE

  6. 24. Gas Mixing in a Circulating Fluidised Bed Boiler

    Author : Johan Sternéus; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circulating fluidized bed; gas mixing; tracer; boiler; dispersion; scaling; turbulence; two-phase flow; fluidization;

    Abstract : The present thesis is a study on the gas-mixing behaviour in a circulating fluidised bed (CFB) boiler. The aim is to describe how gas is spread in different regions of a CFB furnace and to explain variations in the mixing rate under different operating conditions. READ MORE

  7. 25. Experimental Investigations on Natural Gas-Diesel Dual Fuel Combustion

    Author : Pablo Garcia; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual Fuel; Diesel; Natural Gas; Pilot Injection; Combustion Efficiency; Methane; Nitrogen Oxides; Lean operation; Ignition;

    Abstract : Natural gas has been traditionally applied in spark-ignited combustion engines due to similar combustion characteristics for methane gas and gasoline. However, spark ignition requires a low compression ratio to avoid knock problems and therefore, gas engines have lower efficiency than diesel engines. READ MORE
