1. 11. On Transfer of Work Material to Tools

   Författare :Jannica Heinrichs; Staffan Jacobson; Urban Wiklund; Uppsala universitet; []
   Nyckelord :Tribology; Friction; Forming; Cutting; Galling; Material transfer; Tribological coatings; Surface finish; Micro mechanisms; Aluminium; Materialvetenskap; Materials Science;

   Sammanfattning : Bulk forming and cutting are widely used to shape metals in industrial production. Bulk forming is characterized by large strains, extensive plastic deformation and large surface expansions. Cutting is characterized by high speeds, high pressures and high temperatures. LÄS MER

3. 12. Micro-Foundations of Organizational Adaptation : A Field Study in the Evolution of Product Development Capabilities in a Design Firm

   Författare :Carlo Salvato; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Organizational adaption; Organizational evolution; Organizational replicators; Organizational routines; Firm competences; Dynamic capabilities; Organizational learning; New product development; Business studies; Företagsekonomi;

   Sammanfattning : The aim of this dissertation is to improve knowledge of how organizations adapt to their dynamic environments, by developing a detailed understanding of the configuration and evolution of organizational replicators. Among open questions in the literature on organizational adaptation, I have explored the following: How can the structure of organizational replicators and the nature of their components be realistically described? How do different organizational replicators interact with each other at different levels within and across organizational boundaries? How do replicators evolve? Why do firms need dynamic capabilities? I’ve addressed these questions by means of an embedded, longitudinal field study of Alessi, an Italian firm founded in 1921, active in the development and production of hundreds of design household products.

4. 13. CANCER-RELATED GENE REGULATION MECHANISMS

   Författare :Srinivas Veerla; Avdelningen för klinisk genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Cancer is a disease characterized by deregulation of cellular functions. The means by which these changes occur may differ among cancer types. However, common to all cancers are that they have changed the genetic programs that determine their characteristics. Genetic programs are mainly regulated by the action of transcription factors.

5. 14. Enter the Dragon : Toward a Micro-political View on Subsidiary Initiatives

   Författare :Alexander N. Gorgijevski; Christine Holmström; Katarina Lagerström; Jens Gammelgaard; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Multinational corporation; Subsidiary initiatives; Micro-political view; headquarters-subsidiary relationship; headquarters attention; initiative-selling; Business Studies; Företagsekonomi;

   Sammanfattning : Subsidiary initiatives are proactive, entrepreneurial activities that arise locally without central directives or planning from headquarters. Prior research suggests that subsidiary initiatives are crucial to multinational corporations’ (MNCs) success in foreign locations as they hold the potential to enhance local responsiveness, worldwide learning, and global integration by the leveraging of new knowledge.

7. 15. Microstructure and wear mechanisms of textured CVD alumina and titanium carbonitride coatings

   Författare :Siamak Shoja; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plastic deformation; Texture; TKD; Electron microscopy; Coatings; CVD; TiCN; α-alumina; Wear mechanisms;

   Sammanfattning : The aim of this thesis is to find the reasons behind how the wear performance of hard coatings produced by chemical vapor deposition (CVD) is influenced by their texture, as this is today not fully known. Therefore, differently textured coatings were synthesized, and subsequently analyzed both before and after specially designed machining tests. LÄS MER
