1. 36. Corporate Brand Positioning – Case Studies across Firm Levels and Over Time

   Författare :Christian Koch; Företagsekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Brand positioning; corporate branding; organizational change; strategy formation; process;

   Sammanfattning : Positioning is a key concept in the fields of branding, marketing, and strategy. In brand management, positioning deals fundamentally with finding a balance between sameness and differentiation. Empirical research predominantly examines the effectiveness of certain strategies.

3. 37. Reduction of refining energy during mechanical pulping : using pressurised chip compression and sulphite pre-treatment

   Författare :Erik Nelsson; Geoffrey Daniel; Mittuniversitetet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Chip pre-treatment; double disc refiner; energy efficiency; Impressafiner; low dosage; Norway spruce; refining intensity; single disc refiner; sulphite pre-treatment; thermomechanical pulp;

   Sammanfattning : The effects of pressurised compressive chip pre-treatment and low dosage sulphite pre-treatment were evaluated for production of thermomechanical pulp in mill scale trials using Norway spruce (Picea abies) at the Braviken paper mill (Holmen Paper AB, Sweden). The general aim of the study was to improve the energy efficiency during the production of mechanical pulps suitable for news and improved news grade papers. LÄS MER

4. 38. Optimization models and methods for harvest planning and forest road upgrading

   Författare :Jenny Karlsson; David Martell; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

   Sammanfattning : The purpose of this thesis is to contribute to the development and the use of optimization models and methods to support efficient decision making in Swedish forestry. The main problem areas concerned are forest road upgrade planning and operational harvest planning. Today much of the planning is done manually by experienced managers. LÄS MER

5. 39. Networks and Demand. The Use of Electricity in an Industrial Process

   Författare :Torkel Wedin; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; Networks; Industrial networks; resources; strategy; electricity; pulp and paper industry; actors; Knowledge; Företagsekonomi; Business studies; Företagsekonomi; Business Studies; företagsekonomi;

   Sammanfattning : The formation of demand for an individual resource is examined in a network setting. Demand is seen as an interactive process, where several firms make use of a resource directly and indirectly and, in so doing, shape the primary demand for it. This thesis is also concerned with how an individual firm can influence its demand. LÄS MER

7. 40. Improved energy efficiency in mill scale production of mechanical pulp by increased wood softening and refining intensity

   Författare :Erik Nelsson; Per Engstrand; Birgitta A. Engberg; Rodger Beatson; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis focuses on the electric energy efficiency of single stage double disc refining for production of printing grade mechanical pulp from Norway spruce wood chips. The thesis is based on the hypothesis, that more energy efficiency refining can be attained by balanced increases of wood softening and refining intensity. LÄS MER
