In this thesis a strategy perspective (the resource-based view) is applied to the New Technology-Based Firms (NTBFs) in Science Parks, arguing that the Science Park provides the firms with a set of resources that if used could help them build their resource base and thus develop and grow. Three categories of resources are identified in the Science Park; University related resources, Science Park f
The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. A special interface was created which facilitated information exchange between the two software progra
For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina. This thesis deals with the first of the
Political Culture and Social Engagement. An ethnological study of everyday parliamentary life in Helsingborg. The goal of my thesis is to, by examining foundational features which support political culture, make visible prerequisites for political engagement. Using diverse everyday situations, the thesis describes how one “does” politics. I follow two committee chairpersons in the municipality of
Glycosaminoglycans (GAGs) are members of a family of polysaccharide structures consisting mostly of repeating disaccharide units. Most GAGs are attached to specific serine residues in proteins to form proteoglycans (PGs). GAGs and PGs show a large and diverse number of biological functions ranging from cell cycle regulation and control of formation of blood vessels to modification of tissue transp
Several optically active organometallic Phe-AAn-Phe peptidomimetics and macrocyclic Phe-(Phe)n peptides have been synthesized by either intra- or intermolecular peptide bond formation of the corresponding bis(amino acid) derivatives. The key bis(amino acid) derivatives were available from an improved multi-step synthetic route, utilising Horner-Wadswort-Emmons olefination of organometallic aldehyd
The aim of this thesis was to analyze the value of pictures in a number of cognitive tasks that are predominantly verbal in nature. Three studies, with three experiments each, are included in the thesis. The first study found automatic interference effects from pictures (facial expressions) on the affective evaluation of words. In the Stroop-like presentation of integrated picture-and-word stimuli
This thesis describes the design, synthesis and evaluation of synthetic inhibitors for the carbohydrate binding proteins called galectins. Potent and selective inhibitors can be used as important research tools in the endeavor to chart the true role of galectins in biological events such as cancer and inflammation and possibly as lead for future galectin targeting drugs. A panel of O-galactosyl a
This thesis concerns different kinds of tunneling based devices all showing negative differential resistance. The thesis is divided in three parts, resonant tunneling transistors, Esaki diodes and coupled zero dimensional systems. The resonant tunneling transistors are GaAs-based vertical field effects transistors, based on a combination of overgrown tungsten gates and double barrier heterostruct
By using ancient texts, medieval documents, philological observations, and archaeological artifacts, scholars have reconstructed a prehistorical world and religion. The people who upheld this culture have been named, inter alia, "Indo-Europeans", "Aryans", "Japhetites" and "Wiros". Yet, these people have not left any texts, no artifacts can with certainty be ascribed to them, nor do we know any in
During the past twenty years, considerable efforts have been invested in fundamental research on the thermochemical conversion of alternative solid fuels and on its areas of application. Today, the attempt is being made to develop processes for upgrading those fuels to become easy accessible energy sources of high efficiency. The thesis concerns thermochemical means for utilizing biomass. Light i
Efficient sorting and searching are corner-stones in algorithm design. In computer science it has become a deep-rooted habit to use comparison-based methods to solve these problems. In this thesis we argue that radix sorting and searching algorithms are superior in many respects, both practical and theoretical. They are often remarkably simple and many, if not most, sorting and searching problems
Bob Dylan (b. 1941) became known as an enfant terrible and a regenerator of rock lyrics already in the tumultuous 60´s. His constantly shifting roles as musician and songwriter, combined with his notable reserve, have led to the growth of a plethora of myths surrounding his person and work. His lyrics, accompanied by an increasingly original rock backing, based on folk music and rhythm & blues
Tröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. It has also been shown that anilines without substituents in para-po
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 current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. One possible way towards a more simple exhaust aftertreatment system is the use of the Homogeneous Charge Compression Ignition (HCCI) engine cycle. The main advantage o
This thesis aimed to investigate visual-vestibular interactions in healthy subjects and in patients with a well defined unilateral vestibular lesion (vestibular schwannoma before and six months after translabyrinthine surgery). Visual information is particularly important for balance control during perturbed stance. The physical act of having the eyes open or closed affects motion strategy in pos
Type 2 diabetes is a disease that increases tremendously in the western world. It is characterized by insulin resistance and defects in insulin secretion. Insulin resistance is tightly linked to obesity, and usually precedes the onset of type 2 diabetes. When insulin resistance develops, the pancreatic beta-cells compensate by in¬creasing their secretion of insulin, causing hyperinsulinemia. This
Obesity is increasing throughout the world at an epidemic rate, partly due to increased consumption of diets rich in fat and/or sugar. Ghrelin and leptin are hormones, originating from the periphery, involved in the regulation of food intake and of maintaining energy homeostasis. Circulating ghrelin levels increase in times of energy deficiency, such as fasting, signalling hunger whereas circulati
