Regulation of blood flow involves several endogenous substances and mechanisms, and exogenous substances may also affect the blood flow. In the present thesis, human omental blood vessels were investigated in vitro concerning (i) characteristics of 5-hydroxytryptamine (5-HT) receptors; (ii) mediators of substance P (SP)-induced relaxation; (iii) direct and indirect (via effects on sympathetic neur

Immunological self-tolerance is a state of the whole organism where deleterious responses are either avoided or regulated. Breaking of immunological tolerance will lead to autoimmune disease or chronic inflammatory conditions. T cell maturation in the thymus generates a peripheral T cell pool with an enormous TCR repertoire, from which specific T cells are selected and activated upon encounters wi

This thesis addresses solving elliptic partial differential equation using integral equation methods, with emphasis on accuracy, speed and stability. Of particular interest are such equations on non-smooth domains, and several different elliptic problems such as electrostatic and elastostatic ones are treated and solved in this setting.

Rare-earth ions doped into a transparent crystal can have optically excited states with coherence times of milliseconds and hyperfine levels with coherence times of hours when cooled down to liquid helium temperatures. This makes them attractive for developing quantum computing hardware. A quantum transistor can be implemented in a rare-earth-ion-doped crystal by utilizing a dipole blockade effe

Starting from Theodor Adorno´s assertion that art is negative knowledge of the real world, the book analyses Indonesian literature produced during the New Order which deal with the events of 1965-1966 and its consequences. A number of Indonesia´s best known authors have written on the subject. The central issue raised is the extent to which this literature has contributed to undermining and thereb

The aim of this dissertation is to find relationships between folk art, an artist's personal life and influential factors originating in the context. Christmas wall hangings by the peasant painter Johannes Nilsson (1757­1827) are the focus of the study. The fact that he had a special approach to the painting tradition raises two questions: Why did he paint the way he did? How can his hangings be i

Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. I have shown that the thymidine and leucine incorporation techniques are w

A laser-produced plasma was generated by focusing 100 fs laser pulses, with an energy of 150 mJ, onto metal targets. The laser intensity was expected to reach 10E17 W/cm2. Radiation was emitted from the created plasma, with photon energies extending up to the MeV regime. The laser-based X-ray source was optimised, with the purpose of making it a realistic source of hard X-rays (>10 keV). Dedicated

Telomeres are specialized complexes of DNA and associated proteins that protect the ends of eukaryotic chromosomes. Although most organisms have short repeated DNA sequences at their telomeres, which are specified and maintained by the enzyme telomerase, there are a few exceptions. Dipteran insects, including the genus Chironomus (non-biting midges), lack telomerase and have atypical terminal sequ

Harvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment. Species interactions therefore influence the effect of harves

The evaluation of skeletal muscle strength is an important part of the physiotherapist’s clinical examination in order to plan and execute appropriate interventions. This requires the objective assessment of muscle strength and the determination of the underlying factors of muscle weakness. One factor that can contribute to muscle weakness is the inability of the central nervous system to voluntar

Cellulose and starch are non-toxic, biodegradable and modifiable polymers. These properties have made them increasingly important in industrial products e. g. in pharmaceutical applications and in technical dispersions. By chemical modification of these polymers the physical and chemical properties of the polymer can be adjusted to suit a certain area of application. The characteristics of modifie

The proton exchange membrane fuel cell (PEMFC) is currently emerging as an efficient and environmentally friendly power source. The technology is very complex and relies ultimately on materials and components which need further development. One of the major hurdles for advancing the PEMFC technology is currently the demand for new durable low-cost polymeric membranes that will allow fuel cell oper

Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. Since an estimated 50% of all clinical drugs act on 30 known GPCRs, the rem

The modern world is increasingly dependent of the use of chemicals. The chemical industries have greatly contributed to the high standard of living in industrialised societies, and chemical compounds surround us in everyday life. Unfortunately, a vast number of chemicals cause adverse effects on the environment and human health. One such concern is chemical hypersensitivity, which is a state cause
