This article proposes an agenda for political participation research aimed at providing empirical answers to questions derived from normative political theory. Based on a threefold distinction between responsive, participatory and deliberative models of democracy, the article first distinguishes three conceptions of political participation: as influencing attempts, as direct decision making, and a
A series of analogs with nitro or serinamide substituents at the C-2'-, C-5'-, or C-C-position of the combretastatin A-4 (CA4) B-ring was synthesized and evaluated for cytotoxic effects against heart endothelioma cells, blood flow reduction to tumors in SCID mice, and as inhibitors of tubulin polymerization. The synthesis of these analogs typically featured a Wittig reaction between a suitably fun
The aim of this study was to test the feasibility of two instruments within an Icelandic context, the Brief Symptom Inventory 18 (BSI 18) and the Ways of Coping Inventory – Cancer Version (WOC-CA) with specific focus on gender and type of treatment and coping techniques among cancer patients during time of treatment. The sample consisted of 40 cancer patients in three oncology outpatient clinics i
Transport policies often contain explicit goals for the travel quality of disabled passenger groups. Addressing the user perspective, focus group discussions with wheelchair-seated passengers (using bus transit and Special Transportation Services) were therefore held, in order to qualitatively explore perceived comfort and safety - two important quality factors. The comfort and safety constructs w
This paper includes 19 saxicolous species of Caloplaca from North and Central America that are characterized by distinctive elongated marginal lobes, non-paraplectenchymatous hypothecium, and presence of anthraquinones. In various ways this group has been referred to as Caloplaca section Gasparrinia or even separated at the generic level. The group, however, is not regarded as natural and conseque
Neural stem cells are defined as cells that either gives rise to or derives from the cells of the central nervous system and have the unique properties of stem cells, i.e. self-renewal and multipotentiality. One of the widely used methods of expanding neural stem cells under culture conditions is based on the capacity of these cells to divide continuously when cultured in serum-free medium supplem
This paper is a contribution to the never settled debate on reference, negation and presupposition of existence in the linguistic/philosophical literature. Based on Swedish and English data, the discussion is an attempt to present a unified account of the opposing views put forward in the works of Aristotle, Frege (1892), Russell (1905) and Strawson (1950). The starting point is the observed asymm
The position of English vis-à-vis Swedish in Sweden is gaining attention because of a growing concern that the encroachment of English in certain domains may result in Swedish losing ground. A current language policy proposal, entitled Mål i mun, commissioned by the Swedish government addresses this concern, in part, by outlining recommendations for the respective roles of Swedish and English (a)
Electron–ion coincidence measurements with energy-resolved electrons are a powerful tool in studies of molecular fragmentation processes, since fragmentation from a specific doorway state can be monitored while the remaining reactions are discriminated. Presently, we have applied this technique in measurements of coincidence spectra of the CD4 and SF6 molecules after valence and core electron exci
Net CO2 emissions have been calculated for the production and transportation of biomass in Swedish agriculture and forestry, using fossil-fuel-based energy inputs. An analysis of how a transition from a fossil-fuel-based energy system to a CO2-neutral biomass-based system would affect the energy efficiency in biomass production and transportation, has also been carried out. Production and transpor
Chondrules are millimeter sized objects of spherical to irregular shape that constitute the major component of chondritic meteorites that originate in the region between Mars and Jupiter and which fall to Earth. They appear to have solidified rapidly from molten or partially molten drops. The heat source that melted the chondrules remains uncertain. The intense radiation from a gamma-ray burst (GR
Measurements of the Xi(-) and (Xi) over bar (+) masses, mass differences, lifetimes and lifetime differences are presented. The (Xi) over bar (+) sample used is much larger than those used previously for such measurements. In addition, the S production rates in Z -> b (b) over bar and Z -> q (q) over bar events are compared and the position xi* of the maximum of the distribution in Z -> q (q) over
In this thesis we characterize the effect of mesenchymal progenitor cells (MPCs) on tumour growth, and show that MPCs can have inhibitory effects on tumour development. We developed a method to subcutaneously transplant tumour cells, cultured in vitro in a pre-formed gelatin matrix, that made it possible to study the early phases of tumour development. Using this method we inoculated rats with gel
Acute myelogenous leukemia (AML) is characterized by the accumulation of immature cells due to disturbed differentiation and proliferation of the myeloid lineage. Genetic alterations affecting transcription factors and receptor tyrosine kinases have been identified in AML and causally linked to the disease. The goal of this review is to address the role of the different genetic alterations in self
Using a combined experimental and theoretical approach, we show that the initial oxidation of a Rh(553) surface, a surface vicinal to (111), undergoes step bunching when exposed to oxygen, forming lower-index facets. At a pressure of about 10(-6) mbar and a temperature of 380 degrees C this leads to (331) facets with one-dimensional oxide chains along the steps, coexisting with (111) facets. Furth
Hypersecretion of airway mucus is a characteristic feature of chronic airway diseases like cystic fibrosis (CF) and leads via impairment of the muco-ciliary clearance and bacterial superinfection to respiratory failure. The major components of the mucus matrix forming family of mucins in the airways are MUC5AC and MUC5B. To investigate the expression of these glycoproteins in CF, immunohistochemis
This thesis presents a study on performance analysis and optimal design of heat exchangers and heat exchanger networks. The study includes an experimental investigation of steam condensation in plate heat exchangers, optimal design of plate heat exchangers and plate-fin heat exchangers, and optimization of heat exchanger networks. In the experimental investigation of steam condensation in plate h
