BECC has, together with the SRA MERGE, a stakeholder reference group. Its members are high-level experts, representing government authorities, branch organisations, companies and NGOs in areas of agriculture, forestry, nature conservation and climate change. The Stakeholder Reference Group convenes annually with the Boards of BECC and MERGE. As one basis for the choice of research problems addres
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
A tool suitable for conducting industrial fire and explosion hazard analysis is presented, together with an identification of weak links in the hazard evaluation chain. For some of the weak links additional research has been carried out. The tool, "FREIA", evaluates the consequences for humans and components due to fires and accidental releases indoors and outdoors using established engineering m
This book is about elections and democracy in newly democratizing countries. Building on a new data set of 5,568 observations in 232 elections, it provides evidence elections have a casual impact on improving the quality of democracy in Africa in more than one way. The study demonstrates multiparty elections do not signal the end of transitions to democracy but rather foster liberalization and hav
This thesis deals with the recent discourse about Hittite ritual and religion and assumes an alternative approach. It analyses how the most important researchers in the fields of Hittitology and History of Religions, who have been working with Hittite rituals and religion, describe and explain the rituals. Their implicit or explicit theories underlying the discourse are explored. The restraining e
The purpose of this thesis is to describe, analyse, and compare the recontextualisation of social pedagogy in three different curricula; in Nijmegen (NL), Lillehammer (N), and Sligo (IRL). The curricula represent different academic orientations and are located in different social-political contexts. The recontextualisation of social pedagogy, the concept derived from the works of Basil Bernstein,
Friction-related problems are frequently encountered in control systems. This thesis treats three aspects of such problems: modeling, analysis, and friction compensation. A new dynamic friction model is presented and investigated. The model is described by a first order nonlinear differential equation with a reasonable number of parameters, yet it captures most of the experimentally observed frict
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
One of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. The large amount of experimental work and reluctance for changing existing processes has caused the pharmaceut
Risk analysis and intervention planning are important in fire prevention and risk management strategies. This study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media. Data from the London Fire Brigade (UK) were used to investigate a possible correlation between the
Although there is a fairly large number of books and articles concerning the validation of technical measurement systems, there are only a few which take into account the whole measurement system consisting of both technical and non-technical aspects. A measurement system comprises both the measurement process and the human being who conducts the measurement. In this way, the human being may be a
The principles of sanctity of life and quality of life are often appealed to in medical decisions at the "edges of life." Notwithstanding their importance in bioethics, these principles are still badly understood. This study is an attempt to clarify their normative significance and content. Because these principles pertain to the more general question of the value of life, the study begins by exp
A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. Formulas for in-rack flame height, excess gas temperature, gas velocity and heat flux to storage walls are provided. The formulas include overall heat release rate,
The work examines developments in the novel and the short story of writers who grew up during the New Order era (1966-1998) in the period of reform post 1998. It is assumed and subsequently affirmed that the genres are developing, modern genres in dialogue with the past and present. The work's main use of theory is that of M. M. Bakhtin's ideas of dialogism. The assumption of 'novelization' is fra
The aim of this dissertation is to study some of the forces behind the transformation of the 20th century industrialised countryside. The emphasis is on changes in everyday life for women and men, and the role of organisations therein. Two main questions are outlined: Which forces were central to the development of the industrial society?, and, how did the relationship between individual and socie
A noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. A scintillation camera allowing single photon emissi
Water column and sediment profiles of plutonium, americium, thorium and uranium have been obtained in the superanoxic Framvaren fjord, southern Norway. The concentrations of bomb test fallout Pu, Am as well as 'dissolved' Th in the bottom water are the highest recorded in the marine environment. The behaviour of the actinides in the anoxic water mass is to a large extent governed by the behaviour
This thesis deals with three topics related to the Ads/CFT correspondence. In Paper I, solutions describing the geometry of fractional D1-branes of Type IIB string theory are presented. The running coupling constant is computed on the gauge theory side. Paper II uses the idea that the anomalous dimension of a gauge theory operator can be interpreted as an eigenvalue of a spin chain Hamiltonian.
During the 1700's lifestyle and material culture varied a lot between towns and rural areas. The aim for this thesis is to study how this difference between town and countryside emerges and how an identity as a burgher or farmer will manifest itself in the material culture. An important question is if it is possible to find a particular urban lifestyle and if that is the case, what it looks like.
Increasingly cities compete for tourist dollars, shoppers, financial investments, know-how and tax-payers by bolstering the cities images as centers of creativity, innovation, knowledge, art, design and so forth. Accelerated and intensified globalization, technological advances, market deregulations,de-industrializations and socio-economic change have urged cities, especially former industrial cit
