The objective of this thesis was to find ways to improve combustion and reduce emissions from supercharged natural gas engines. In-cylinder flow measurements were made with laser doppler velocimetry, LDV, heat release was calculated from cylinder pressures and emissions were measured at various locations. The original combustion chamber was a low turbulence-generating geometry, resulting in an ove

Children whose parents suffer from mental illness are a neglected group. The child´s need of a secure predictable grown up, is not always compatible with the parents abilities to care for the child. The objective in the thesis is to study and analyse preschool teacher´s development in relation to an in-service training for a period of three years and to study the development of the teacher´s work

A network mechanics model for cellulose fibre fluff is proposed. 2D and 3D versions of the model have been implemented and the influence of various micro-level parameters on the global mechanical performance has been determined by means of computer simulations. Model networks composed of bonded fibres of arbitrary distribution in length, curvature, cross-section, stiffness and strength were inves

This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. The net heat release profile is computed from the cylinder pressure trace and quantifies the

The empirical work rests on two separate theoretical foundations: theories that form the basis for analyzing the different target groups and theories dealing with persuasion. Theories of the first sort concern life-style, individual values, perceived risk, individual characteristics and self-image. Earlier research on young car drivers is also relevant in this context. Theories on attitudes and at

The subject of this thesis is the Copenhagen Gospel Book , written and illuminated in England c 970 with additions from c 1020. The thesis is divided into three main parts focusing on different aspects of the manuscript. The first part deals with problems concerning provenance, palæography, later additions and the physical architecture of the manuscript. The author questions the opinion that the m

The Life of Saint Germer and the Life of Saint Josse are two poems consisting of 874 and 820 octosyllabic verses respectively. They were written in the beginning of the 13th century by Pierre de Beauvais. The two poems are preserved in one manuscript only, the Grand recueil la Clayette, Paris, Bibl. nat. Nouv. acq. fr. 13521, written in the latter half of the 13th century by a scribe who was from

Sequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. By contrast, the geometric representation of the protein chain is detailed. We explore the thermodynamic behav

This dissertation provides an alternative perspective on the process of market integration by focusing on market integration within a nation's borders. The dissertation intends to go beyond traditional integration theory and examine various alternative approaches to market integration by using Lao PDR as an empirical example for assessing these alternative approaches empirically. The main objectiv

The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. Further calculations without the isospin approximation are then done to see if th

The main theme of this dissertation is the question of how young women in the early middle class handled the new demands for marriage based on love instead of on judgements of moral, economy and status. Another theme is the education of these middle class girls around 1800 and the question how this new education interacted with the new demands for love marriage. The German social historian Ulrike

Conditions to promote students' knowledge and education about environment The objectives of this Study are: · To describe and analyse the development of students' knowledge about the environment · To elucidate the nature of student thinking about the environment and, from the findings, to suggest the potential of Environmental Education Environmental education is multi-disciplinary and complex.

The method development research in the field of theoretical chemistry is the never ending quest for methods that are faster, gives more accurate results, and expands the possibilities. The work in this thesis is no exception to that statement. Thus a CI routine more suited for calculations on large active spaces was implemented in the RASSCF code of Molcas; a new scheme for localizing multipole mo

Today the wastage level of fruits and vegetables in the food value chain is around 50 % and we want to contribute so that number can be decreased.  Odd Season sources and purchases fruits and vegetables that companies along the food value chain don’t manage to sell in their
