1. Beam-to-Beam Contact and Its Application to Micromechanical Simulation of Fiber Networks
Sammanfattning : This doctoral thesis covers the topic of modeling the three-dimensional fiber net- works with the finite element method. It contains the part addressing the numerical aspects of the modeling, namely, the contact formulation and application of the developed methods to the fundamental questions such as the effect of randomness in fiber properties and effect of fines and hygroexpansion.

2. Responsibility and health: explanation-based perspectives
Sammanfattning : There is a growing trend of holding people responsible for their lifestyle-based diseases. For example, policymakers as well as researchers have argued that medical conditions caused by smoking, overweight, or extreme sports should be given lower priority in publicly funded healthcare.

Sammanfattning : .... LÄS MER
4. Valuation of retention/formation relationships using a laboratory piot-paper machine
Sammanfattning : The interdependency between filler retention and paper formation is well-known, where a high retention is accompanied by impaired formation. A challenge for today’s papermakers is to increase the competitiveness for uncoated and coated fine paper, by improving the formation at the same level of retention. LÄS MER
5. Energy Export Opportunities from Kraft Pulp and Paper Mills and Resulting Reductions in Global CO2 Emissions
Sammanfattning : With increasing energy prices and increasing demand for CO2-lean energy sources, energy savings in the pulp and paper industry become ever more relevant. Significant energy savings in kraft mills can be made by e.g. improved heat integration and installation of an energy-efficient evaporation plant. LÄS MER
