Anglo-American post-Second World War relations in the Middle East included cases of close cooperation and conflict. An example of the former was the Pentagon Talks in 1947 when an American statement pointed out the general objective of maintaining the security of the Middle East by retaining the British political, economic, and strategic position in areas supported by the United States. An example

The life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri

The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. A thorough characterization of the sensor makes it possible to take advantage of a larger portion of this information for

The sovereignty- and self-determination movements of indigenous peoples are a salient factor on the political agenda in many western world countries. Indigenous peoples in Hawai´i and elsewhere have become increasingly politicised in hope of changing their relationship with the states within which they are located. The discourse of indigenous peoples turn around the concept ”First Nations” whose c

The present study is composed of eight chapters relating to children's rights and child labor activity in the Republic of Paraguay. The problem of child labor in Paraguay is central for this study and the legal ideals that are intended to uphold and strengthen the rights of the child are described and contrasted with the present normative reality in which the children work and live. The discrepanc

The general aim of the investigation is to contribute to the development of a theory of change and learning within the working environment. The specific change processes that were examined, emerged from an interactive initiative for change, intending to facilitate an emancipatory development: employees increasing their control of the work situation, thus improving the quality of service. The empir

The paper making process involves chopping of wood, cooking and forming, followed by dewatering in a vacuum section, press section and drying section. Several models for the most important parts of the paper machine drying section are presented in this thesis to describe phenomena at steady state and during state transitions. New control strategies applicable/useful for both steady-state control a

In this thesis a graphical language for sequential control is presented and its application to batch control is examined and discussed. The name of the language is Grafchart. Its main feature is that it makes it possible to express complicated control problems in a compact and intuitive manner.Grafchart exists in two versions; a basic version and a high-level version. The basic version was availab

While much of semi-arid Africa is still sparsely populated with unused land, there are everywhere pockets of high and increasing population density in attractive locations. Small-scale farmers can respond to beginning land-scarcity in a number of ways. Through migration, through diversification of livelihoods, or through changes in their farming system. Which solution is chosen, depends not only o

Why do some children in the developing world choose to stay out of school? Is it mainly because poverty leaves them with no options or because schooling seems to offer them few benefits? The answers to these questions have profound policy implications. An empirical input into this discussion is the extent to which schooling can actually be perceived as a profitable option in various countries and,

There is an increasing need for education since the workforce of today is expected to be highly educated and continuously learn. Distance education is a powerful response to meet the growing need for education. Online education, here concisely defined as distance education mediated online, is the most common type of distance education. It mainly relies on asynchronous communication although it is

The thesis treats methods for pattern recognition in multichannel electroencephalogram (EEG) signals, for application to diagnostics of epilepsy. Parts I-IV treat methods for feature extraction and clustering of EEG spikes, occurring between epileptic seizures, and part V presents a method for filtering seizure onset EEG signals. In part I, Hermite functions are used for parametric description of

The main purpose of this thesis is the study of the structure and representation theory of simple vertex operator algebras (VOAs) of affine type at admissible levels. To do this, it is crucial to obtain knowledge of the singular vectors which generate the maximal submodules, with respect to which these VOAs appear as irreducible quotients, and therefore a substantial part of the text is devoted to

The rapid development of computer-based design analysis tools and methods such as the finite element method (FEM) within computational structural mechanics (CSM), computational fluid dynamics (CFD), and multi-body systems (MBS) during recent decades has fundamentally changed the way in which products are designed and developed. Among the many advantages observed in industrial practice, one can men

Hydrophobic pervaporation has gained a lot of attention as an alternative process for mild aroma recovery, but the real commercial applications of this process are still in their infancies. Better understanding of mass transport phenomena in composite pervaporation membranes is essential from the point of view of membrane manufacturing, while process simulation is an important tool for predicting

The development of immature progenitor cells into highly differentiated effector cells is a process central in modern medicine with applications in the fields of cell therapy as well as oncology. This thesis is focused on the molecular mechanisms that control the development of B lymphocytes. This is a complex and tightly regulated process involving several stages proceeding from stem cells to ant

Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. Sampling is facilitated for the latter two by the use of pivot

This thesis presents the research performed within two different research groups using heavy-ion induced nuclear reactions. They offer the opportunity to investigate different properties of nuclear matter. The results are based on measurements using a variety of different experimental techniques. The PHENIX experiment measured the production of deuteron and anti-deuterons at mid-rapidity in gold-

Strong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. The ability of the tree to withstand climatic and biotic stress can be lowered by air pollution, especially N deposition, with subsequent alterations in the soil c
