In this thesis a carbon dioxide assisted cooling technique for primarily injection moulds, a part of the so called ToolVac™ moulding technology, has been studied. The cooling technique is based on the injection of liquid carbon dioxide into microporous mould steel. The study is an introductory examination focused on experimental work, of the cooling technique and the possibilities it offers. A tes

To combat climate change, different types of initiatives and policy instruments are required to support the development and dissemination of new energy efficient technologies. What type of policy instruments shall be used is, however, not pre-determined. To advance knowledge in how to design successful policy instruments, evaluations and deep-analyses are needed; this to better understand the role

Helicobacter pylori is the main cause of chronic gastritis and peptic ulcer disease in man and is also associated gastric cancer. The spiral shaped H. pylori moves through the gastric mucous layer and colonises the gastric epithelial cells. H. pylori adheres to specific mucosal structures, including mucus molecules, epithelial cells, glycoconjugates and extracellular matrix (ECM) proteins. The ECM

An analytical stiffness and eigenfrequency model of symmetric parallel 6-6 Stewart platforms (hexapods) is developed based on geometrical design variables to optimize the dynamical performance. The model is based upon Lagrangean dynamics in which the Bryant angles are used for the kinematics formulation. With the analytical eigenfrequency model, optimum stiffness characteristics can be obtained fo

From a company perspective it is easier to develop a marketing strategy within a company than to arrange it in collaboration with others. Internal affairs can be controlled but agreements are left to the discretion of authorities. European competition policy suffers from a system failure discriminating against vertical agreements in favor of integrated organizations. Non-dominant companies should

In this article we analyze what has been achieved by the introduction of the euro in terms of macroeconomic convergence and leveling of competitive prerequisites among the EMU member countries. In particular, has the convergence in nominal exchange rates resulted in divergence in real exchange and interest rates? And how has Finland fared relative to the EMU members? The answer is that real exchan

This article reports on an ongoing sociological study of the first Tibetan refugee settlement established in India, Lukzung SamdruplingLugs zung bsam grub gling located in Bylakuppe near Mysore. Data from camp registers and the old files of the settlement office have been digitalized and subjected to an exploratory analysis that focuses on two interconnected issues: resource competition between th
