  1. 1. Excitation and Ground-State Properties of Natural and Modified Nucleic Acid Bases

    Author : Anders Holmén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio; linear dichroism; DFT; transition moment; tautomerism; structure; IR; spectra; DNA bases;

    Abstract : The nucleic acid bases are the carriers of genetic information in DNA and RNA. They are also the main chromophores of nucleic acids and determine their optical properties and sensitivity to UV radiation. READ MORE

  2. 2. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Author : Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Abstract : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. READ MORE

  3. 3. Kinh Settlers in Viet Nam’s Northern Highlands : Natural Resources Management in a Cultural Context

    Author : Mats Lundberg; Anders Hjort af Ornäs; Hans Holmén; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Viet Nam; northern mountains; highlands; wet rice agriculture; upland agriculture; shifting cultivation; natural resources use; local knowledge; culture; ethnicity; Naturresurser; Vietnam; etniska grupper; Water in nature and society; Vatten i natur och samhälle;

    Abstract : This study deals with the Kinh (or Viet) majority people who have migrated from the lowland Red River Delta to the mountainous areas of northern Viet Nam, and their adjustment to a new social and physical environment. Its aim is to analyse the social and cultural consequences for these migrants when settling in communities populated with people who belong to the national ethnic minorities (the Tày, the Giay and the Ngan peoples).

  4. 4. Study of the activity of catalysts for the production of high quality biomass gasification gas : with emphasis on Ni-substituted Ba-hexaaluminates

    Author : Charlotte Parsland; Jan Brandin; Anders Holmen; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioenergy; catalysis; tars; steam reforming; gasification; hexaaluminate; bioenergi; katalys; tjäror; ångreformering; förgasning; hexaaluminat; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Kemi; Chemistry;

    Abstract : The fossil hydrocarbons are not inexhaustible, and their use is not without impact in our need of energy, fuels and hydrocarbons as building blocks for organic materials. The quest for renewable, environmentally more friendly technologies are in need and woody biomass is a promising candidate, well provided in the boreal parts of the world. READ MORE
