1. 11. Requirements Engineering Supporting Technical Product Management

   Författare :Tony Gorschek; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software engineering; Software Process Assessment and Improvement; SPI; Requirements Engineering; RE; Product Management; Market-driven requirements engineering; MDRE; Requirements abstraction model; RAM; Industry relevant research;

   Sammanfattning : Market-Driven Requirements Engineering (MDRE) handles the continuous flow of requirements in an engineering effort, and is not limited to a development instance but part of technical product management as a whole. The market-driven environment generates large amounts of requirements from multiple sources, internal and external, threatening to overload the technical management of products. LÄS MER

3. 12. Biologically Interesting Compounds from Natural Sources

   Författare :Veronica de la Parra; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytotoxicity; Natural products; terpenoids; vasorelaxant activity; allylmercaptane; diabetes mellitus type II; Organisk kemi; Organic chemistry; Cacalia decomposita; GPR40 receptor; TRP channel;

   Sammanfattning : Natural products have traditionally played a major role in the drug discovery process. Besides constituting extremely popular drugs in the market, and an ever-increasing source of interesting and novel chemical structures, they have also aided the characterization of many a pharmacological target.

4. 13. Natural Products from Cameroonian Medicinal Plants

   Författare :Apollinaire Tsopmo; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; antiplasmodial.; antitrypanosomal; diarylheptanoids; terpenoids; flavonoids; aframodial; Aframomum; Reneilmia cincinnata; Dorstenia; Euphorbia; Lepidobotrys staudtii; Pentadiplandra brazzeanea; Vernonia guineensis; Natural products; Myrica arborea;

   Sammanfattning : Natural product chemistry is a main research area in Cameroon, as well as for the division of Bioorganic Chemistry at Lund Institute of Technology. A review of the results obtained recently with Cameroonian medicinal plants shows that a large number of compounds, many with complex structures, have been isolated and characterised, and the work presented in this thesis is part of this effort.

5. 14. Assessing Sustainability and Guiding Development towards More Sustainable Products

   Författare :Gunilla Clancy; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; action competence; early-stage product development; team learning; wood-based material; role of designer; semi-structured interview; ecolabels; management systems; participatory action research; sustainability assessment;

   Sammanfattning : Companies need to develop more sustainable products that fit into future more sustainable markets. For this reason, the integration of sustainability considerations is needed in the early stages of product development, where a major part of the sustainability performance of a final product is determined.

7. 15. Transition-Metal Catalyzed Synthesis of Small- and Medium-Sized Rings Applications toward oxazole synthesis, cycloheptadienes, and natural products

   Författare :Henrik von Wachenfeldt; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; transition metal; cyclization; cycloaddition; natural product;

   Sammanfattning : This thesis deals with the development of novel methodologies for the synthesis of hetero- and carbocycles enabled by transition metal catalysis. The second chapter of the thesis describes a gold-catalyzed three-component reaction to form a variety of substituted oxazoles from readily available N-benzylimines, terminal alkynes, and acyl chlorides.
