  2. 1. Synthesis of Bioactive Analogues of Marasmane Dialdehydes

    Author : Daniel Röme; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Cancer; Enantioselective synthesis; Totalsynthesis; Semisynthesis; Cytotoxicity; Anti-tumor activity; Isovelleraloids; Marasmic acid; Marasmane dialdehydes; Isovelleral;

    Abstract : The modification of drugs into pro-drugs is an attractive concept allowing you to tweak the chemical and physical properties of a drug without changing the original structure of the active compound. In principle, any compound possessing a preferred biological activity can be transformed into a pro-drug. READ MORE

  4. 2. Novel biologically active compounds by semisynthesis with fungal metabolites

    Author : Johan Eriksson Bajtner; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bioactive compounds.; isovelleral; podoscyphic acid; Natural products; semisynthesis;

    Abstract : Natural products have been shown to be an important source of novel compounds for the development of new drugs and pesticides. However, many biologically active natural products contain reactive functionalities that make them toxic. READ MORE

  5. 3. Traditional lowland rice agriculture in Sri Lanka : Nitrogen cycling and options for biofertilizers

    Author : Ola Palm; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The aim of this thesis has been: to study the dynamics of soil organic-matter, with regard to nitrogen in a traditional lowland-rice agricultural system; to consider options for and nitrogen cycling of biofertilizers, especially the green-manure legume Sesbania sesban; to discuss fertilizer sources and management constraints as parts of a sustainable agricultural development; and to discnss the methodological problems of controlled experiments vs. investigations in farmer's fields.

  6. 4. Impact of fermentation on the nutritive value of cassava root pulp and soybean pulp as a feed for growing pigs in Lao PDR

    Author : Lotchana Taysayavong; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis evaluated the impact of fermentation on the nutritive value of cassava root pulp (CRP) and soybean pulp (SBP) as feed for growing pigs. The evaluation was based on four studies (two fermentation and two animal studies). READ MORE

  7. 5. Characterization and preparation of lightweight silica based ceramics for building applications

    Author : Edwin Escalera; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Bolivia is a country with considerable quantities of non-metallic resources. Some important deposits of these resources are located in the high and cold Altiplano as well as in the tropical areas. These deposits are not being exploited industrially but both areas have production of some ceramics in a handmade and empiric way. READ MORE
