– Att förstå mänsklig och naturlig påverkan på klimat och luftmiljö Människans energiförbrukning ökar i stadig takt med jordens befolkning och fokus på klimatförändringar gör att efterfrågan på hållbar energi har blivit stor. Ett alternativ till fossila bränslen är de så kallade ”andra generationens biobränslen”. Dessa kan tillverkas av cellulosa från träd och gräs som inte är värdefulla som livsmFourier transform infrared spectroscopy techniques were used to study the kinetics of gas-phase reactions of three lactones, γ-valerolactone (GVL), 2(5H)-furanone (2(5HF) and 3-methyl-2(5H)-furanone (3M2(5H)F) with Cl atoms, OH radicals and O3 respectively. The experiments were performed in a photochemical reactor at a total pressure of 700 Torr at room temperature (298±2 K). Both relative rate an

När vi tittar upp mot himlen kan vi urskilja skenet från tusentals strålande stjärnor. En mörk natt kan man också förnimma ett ljussvagt stråk som spänner över himlen; Vintergatan. Stråket består av (för ögat) oupplösta stjärnor, som tillsammans med gas och stoft sammanfogats under gravitationens inverkan för att, över tid, bilda vår hemgalax. Tittar man med ett teleskop kan man se en enorm variatContext. Effective temperature is one of the fundamental stellar parameters. A traditional spectroscopic way to determine it is from optical spectra using excitation balance of Fe-lines. With technological advances and the advent of the next generation telescopes there will be an emphasis on the relatively unexplored near-IR (NIR) wavelength region (1-5 μm). A method to determine the effective tem

This research seeks to find how the Spanish society perceives Personal Income Tax compliance. By following the Slippery Slope Framework developed by Kirchler (2008) the study aims at measuring perceived trust and power of Spanish authorities. Higher levels of trust in authorities and power of authorities are proportional to raised levels of tax compliance. Estimating respondent´s perceptions as to

In cognitive linguistics there are three prevalent theoretical perspectives on metaphor: (universal) conceptual metaphors, discourse metaphors and language-consciousness interactionism. This thesis looked for evidence of support for these positions by conducting an empirical study comparing motion-emotion metaphors in English, Spanish and Swedish, focusing on the source domain MOTION. Following th

The aim of this study is to understand how crowdsourcing campaigns in an online environment can change brand perceptions and behavioral intentions of non-participating customers. Therefore, the thesis connects two major concepts. First the phenomenon of crowdsourcing will be discussed with emphasis an emphasis on its use in marketing. Then crowdsourcing will be lined to the theoretical concept of
