    Sammanfattning : This thesis describes methods to obtain value–addedcompounds from TMP-turpentine obtained from the spruce, Piceaabies. The methodology focuses on biotransformations using twoapproaches: an oxygenation approach (i.e. oxygenation ofterpene hydrocarbons by cell cultures) and an esterificationapproach (i. LÄS MER

  3. 2. Internal rotation in molecules : a nuclear magnetic resonance relaxation study

    Författare :Anders Ericsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In order to study the internal rotation of methyl-type groups in molecules, the carbon-13 nuclear magnetic resonance (NMR) spin-lattice relaxation times (T1) and nuclear Overhauser enhancement factors (n) are measured for some terpenes (borneol, camphor, isopinocampheol and α-pinene), for octafluorotoluene and for 1-methylnaphtalene. In addition, deuterium NMR T1 data are presented for 1-methylnaphtalene-d10. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amomum; Zingiberaceae; Flore du Cambodge du Laos et du Vietnam; Taxonomy; Ethnobotany; Postpartum; Mother roasting; Hotbed; Brou; Saek; Kry; Lao PDR; Organism biology; Organismbiologi; Systematics and phylogenetics; Systematik och fylogeni; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : The species of Amomum Roxb. (Zingiberaceae) in Cambodia, Laos and Vietnam are revised. Thirty-five species and two varieties are recognised, all names are typified, and detailed descriptions and a key are provided. Nine new species are described and one species is validated. LÄS MER

  5. 4. Odours attracting Medetera (Diptera) predators to spruce bark beetles in a multitrophic system

    Författare :Maria Sousa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Tree-killing bark beetles cause great economic and ecological damage worldwide. Several long-legged fly species of the genus Medetera are natural enemies of tree-killing bark beetles and are of interest as potential biological control agents. LÄS MER
