    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

    Abstract : Popular Abstract in Swedish Ta ett djupt andetag och tänk på vad du nu har i lungorna! Jo, det är luft, förstås, syre kväve och sådant. Men det är också något annat. I varje kubikcentimeter du andas in finns tusentals partiklar, alla för små för att kunna ses med blotta ögat. Om dessa partiklar handlar denna avhandling. READ MORE

  2. 2. Biotransformations of Turpentine Constituents Oxygenation and Esterification

    University dissertation from Stockholm : Kemi

    Author : Marica Lindmark-Henriksson; KTH.; [2003]
    Keywords : Picea abies; Pinaceae; Essential oils composition; Terpene alcohol; Hemiacetal; Hemiacetal ester; TMP-turpentine; Monoterpene; alpha-pinene; beta-pinene; Limonene; Verbenol; Pinocarveol; Borneol; Myrtenol; Suspension cell culture; Biotransformation; ;

    Abstract : 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. READ MORE

  3. 3. Is genetic diversity more important for terpene emissions than latitudinal adaptation? : Using genetically identical trees to better understand emission fluctuations across a European gradient

    University dissertation from Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science

    Author : Ylva van Meeningen; Lunds universitet.; Lund University.; [2017-04]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BVOC; English oak; European beech; Norway spruce; genetic diversity; European gradient;

    Abstract : Biologiskt flyktiga organiska ämnen (BVOCs) är spårämnen förutom CO2 och CH4 som produceras och släpps ut av växter. Termen innehåller tusentals olika ämnen i varierande former och storlekar och där ämnena har korta atmosfäriska livstider. Några av de vanligaste BVOC grupperna kallas isopren, monoterpener och sesquiterpener. READ MORE

  4. 4. Conifer chemical defense Rugulation of bark beetle colonization and pheromone emission

    Abstract : Terpenes and phenols are of importance in conifer defense against insects and pathogens. Knowledge about tree chemical defense is vital for developing practical methods to maintain healthy forests. READ MORE

  5. 5. Emissions of volatile organic compounds from wood

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Karin Granström; Karlstads universitet.; Karlstads universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; Miljö- och energisystem; Environmental and Energy Systems; VOC; terpenes; drying; wood; emissions; spouted bed;

    Abstract : The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds.The purpose of this work was (1) to develop a method to establish the amount of emitted substances from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbons, (3) to examine the emissions of monoterpenes during production of pellets, and (4) to examine the natural emissions from forests with an eye to implications for modelling.
