An investigation of improvements of myoelectric prostheses has been undertaken. The primary aims of this thesis were (1) to generate an accurate prediction of as many hand movement as possible, (2) to produce a training setup for subjects allowing intuitive and instant control over multiple movements, and (3) to reduce the training cycle for the control system to a maximum of a couple of minutes t
A number of analogues of (Z)-5-decenyl acetate (1), a pheromone component of the turnip moth, Agrotis segetum, have been synthesised and tested by using single-cell electrophysiology, in order to investigate the relationships between structure and activity, and to elucidate the interactions between 1 and its receptor. Molecular mechanics and ab initio quantum mechanical calculations have been used
Several aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. The first part deals with the formation of SBA-15, it is found that a
Cytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. Little is known about the bacterial cytochromes P450. I have in my thesis given an over
Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. After release into the atmosphere, the particles are subjected to complex dilution and transformation processes that are of
The aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the
Coagulation factor IX (FIX) is a vitamin K-dependent serine protease zymogen that circulates in plasma. Defects in FIX cause the bleeding disorder hemophilia B. FIX contains a Gla module, two Epidermal Growth Factor (EGF) -like modules and a serine protease region. In this thesis, studies have been performed on the N-terminal EGF module, which binds one Ca2+. — The present results show that bindin
A broad, distinctive material presentation is done, which is linked to some variables of psychological value, stating a research for the authenticity of Garborg in viewing him as well a symptom bearer as a symptom solver. An introduction to Garborg is meant to be an invitation, especially to those who are not so well acquainted with him as a person and a writer. Out from a period of about 110 year
Cognitive models of anxiety postulate that anxious individuals are inclined to pay more attention to negative than to positive emotional visual stimuli. The main aim of the present dissertation was to test this prediction, employing a measure of the direction of gaze. In studies I, II and III the participants were shown pairs of angry and happy faces on a screen. In Study IV the stimuli were pleas
Radiotherapy is one of the major tools for treating cancer. Through research and technical development radiotherapy is becoming more advanced with new treatment techniques emerging. In the work presented in this thesis, well-known methods have been used, or modified for use, and new methods have been introduced in order to optimise the clinical use of an advanced radiotherapy treatment technique,
Groundwater depletion in arid and semiarid areas is of increasing concern. Increasing water demand due to increasing population and climate change impacts have intensified the water shortage problems and put further stress especially on groundwater. Water harvesting techniques have been traditional solutions to water scarcity problems in the arid and semiarid Middle East for thousands of years. Th
In Northern Ireland and South Africa obstacles to reconciliation were found in these elements of a “moral landscape”: – Experiences of trauma, separation and inequalities, – Divergent views of the conflict and of “the other”, – Opposing identifications and loyalties, – Norms for interaction, – Contestant interpretations of values such as “peace” and “justice”. This study describes how these obstac
In international commerce, various taxes and charges are levied on commodities; besides, goods may be subject to import and export restrictions. However, free-trade agreements may stipulate that some goods can be imported and exported free of charge. The regulations pertaining to different types of merchandise are reflected in the customs tariff of a state or customs union. The application of many
In 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. The interesting biological properties and the unique structural characteristics of the transtaganolides/basiliolides (the
This dissertation aims at showing that Chrétien de Troyes' Conte du Graal does not, as often affirmed, uphold traditional chivalrous values, but discloses a problematic ideology, mostly as a result of multiple interactions at the textual level. In order to examine ideology, Le Conte du Graal is analysed in the light of the poetics elaborated by Vincent Jouve in his Poétique des valeurs (2001). Fol
Calculations on a Homogeneous Charge Compression Ignition (HCCI) engine have been performed. Zero-dimensional models were used. The simplest model compressed the gas to auto-ignition, using temperature and pressure at a certain crank angle position obtained from engine experiments. It was found that calculations with good agreement could be accomplished, if using correct temperature, pressure and
This dissertation is about the way buildings archaeology approaches historical buildings. The aim is to show how buildings archaeology can be renewed and developed. The motivation is my belief that buildings archaeology does not fully utilize the potential of standing buildings as historical sources, which is mainly due to the traditional outlook on buildings as two-dimensional objects. When three
In this dissertation I have sought to test the possibility of recreating a detailed picture of an individual medieval person, tracing the Danish archbishop Absalon's own world of thought and action through those surviving sources that he has left behind. The sources are both written and material, and they include the cloister church in Sorø, the Havn Castle, the Medieval history Gesta Danorum, the
