1. 1. Essays on Wage and Price Formation in Sweden

   Författare :Kent Friberg; Eskil Wadensjö; Henry Ohlsson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; wages; prices; sectoral wage linkages; real wage determination; vector error correction models; Economics; Nationalekonomi;

   Sammanfattning : Study IReal Wage Determination in the Swedish Engineering IndustryThis study uses the monopoly union model to examine the determination of real wages and in particular the effects of active labour market programmes (ALMPs) on real wages in the engineering industry. Quarterly data for the period 1970:1 to 1996:4 are used in a cointegration framework, utilising the Johansen's maximum likelihood procedure. LÄS MER

3. 2. Effects of Varying Combustion Conditions on PCDD/F Formation

   Författare :Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

   Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. LÄS MER

4. 3. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass

   Författare :Anna Strandberg; Markus Broström; Rainer Backman; Christoffer Boman; Maria Zevenhoven; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Char conversion; pyrolysis; devolatilization; ash transformation; biomass; fuel characterization; fuel composition; ash composition; silicate formation; carbonate formation; thermogravimetric analysis; micro-tomography;

   Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER

5. 4. Chromatin Structure: Nucleosome Formation and Positioning

   Författare :Hans R. Widlund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; centromere; formation; chromatin; nucleosome; telomere;

   Sammanfattning : In all eukaryotic cells the DNA is complexed with a group of highly basic histone proteins forming nucleosomes and higher order chromatin structures. In the nucleosome the DNA is tightly wrapped, almost two turns, around an octamer of histone proteins. LÄS MER

7. 5. Dissipative formation of galaxies in hierarchical cosmology

   Författare :John Hultman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; merical methods; hydrodynamics; galaxies: formation; galaxies: elliptical; galaxies: structure; star formation; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Theoretical Astrophysics; teoretisk astrofysik;

   Sammanfattning : A description and detailed tests of a numerical code for simulations of galaxy formation is presented. The dynamics is followed with fully adaptive and Lagrangian Smooth Particle Hydrodynamics (SPH) combined with a gravitational tree method. The severe numerical problem of sub-resolution clustering is solved by merging of gas particles. LÄS MER
