  2. 1. Nominal Compounds in Old Latvian Texts in the 16th and 17th Centuries

    Author : Kristina Bukelskytė-Čepelė; Jenny Larsson; Peteris Vanags; Jurgis Pakerys; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; nominal compounds; compounding; Old Latvian; Lithuanian; Baltic languages; philology; historical linguistics; determinative compounds; possessive compounds; verbal governing compounds; copulative compounds; baltiska språk; Baltic Languages;

    Abstract : This thesis investigates the system of compounding attested in the earliest written Latvian texts of the 16th and 17th centuries. The philological analysis presented in this work is the first systematic attempt to extensively treat compounds in Old Latvian. READ MORE

  5. 3. Lignin-carbohydrate complexes: Model compounds synthesis

    Author : Filip Nylander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lignin-carbohydrate complex; lignin model compounds; lignocellulose;

    Abstract : In lignocellulose there is a recalcitrant interaction by covalent and non-covalent bonds called the lignin-carbohydrate complex. This interaction has been the subject of studies trying to unveil its chemical structure, to understand the mechanims involved in its formation and to determine its influence on practical applications such as the process of turning biomass into ethanol.

  6. 4. Lignin Model Compounds: Synthesis, Stereochemistry and Acidolysis

    Author : Shiming Li; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boric acid complexes; Arylglycerol b-aryl ethers; stereochemistry; 3-Diaryl-2-propen-1-ols; 1; Phenylcoumarans; lignin model compounds; acidolysis; ion-exchange chromatography; 3-propanediols; 2-Diaryl-1; 2; X-ray crystallography;

    Abstract : Lignin model compounds representative of structural elements in lignin of the b-1, b-5, b-O-4, cinnamaldehyde and cinnamyl alcohol types were synthesized. erythro-Forms of b-1 models of the 1,2-diaryl-1,3-propanediol type were prepared by BF3-catalyzed rearrangement of chalcone epoxides and subsequent reduction of the rearrangement products with NaBH4.

  7. 5. Emissions of organic compounds from technosphere articles : Measurements and modeling of mass transfer from consumer goods and building materials to air and water

    Author : Tomas Holmgren; Peter Haglund; Martin Scheringer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; model; DINP; DINCH; TiBP; TPP; Vinyl flooring; flat screen displays; LCD screen; concrete; Abraham solvation parameters; Piringer equation; linear free energy relation;

    Abstract : This thesis describes the development of a generic model for predicting the emissions of organic compounds from materials used in the manufacture of various goods and products. Many products contain organic substances that are not bound to the matrix formed by their constituent materials and are thus able to dissociate from the material and become transferred into the surrounding environment.
