Plant Phosphoinositide Kinases. A Study of PtdIns 4-kinases and a PtdIns 4-phosphate 5-kinase.

Popular Abstract in Swedish För att överleva måste alla levande varelser kunna anpassa sig till omgivningen.Detta innebär i sin tur att allt levande måste kunna uppfatta sin omgivning och reagera på dessa intryck.Den minsta byggstenen för allt levande är den enskilda cellen.Alla celler känner av sin omgivning och har möjlighet att reagera på ändrade livsbetingelser.Celler är utrustade med ett antePhosphoinositides are of particular interest in signal transduction processes as they can be sequentially phosphorylated and used as precursors for the intracellular messengers inositol trisphosphate (InsP3) and diacylglycerol (DAG) that in turn affects calcium levels and protein kinase cascades, eventually leading to a physiological response. The activity and regulation of PtdIns 4-kinases and Pt

Policies for the Energy Technology Innovation System (ETIS)

The development and introduction of heat pumps provides an interesting illustration of policy influence and effectiveness in relation to energy technology innovation. Heat pumps have been supported by several countries since the 1970s as a strategy to improve energy efficiency, support energy security, reduce environmental degradation, and combat climate change. Sweden and Switzerland have been es

Relaxed Optimal Control of Piecewise Linear Systems

This paper applies a dynamic programming relaxation methodpreviously proposed by the authors to optimal control of piecewise linearsystems. The method gives an algorithm to find a sub-optimal valuefunction and control law within a user-specified distance from theoptimal solution. For computational reasons, the value function usedin this paper is piecewise quadratic and continuous. It cannot, ingen

Integrity Warriors: Global Morality and the Anti-corruption Movement in the Balkans

This article discusses the rise of "anticorruptionism" as part of a general trend in "ethical globalization", and offers an anthropological framework for studying anticorruption movements. Focus is on the organization Transparency International and its operation as an international NGO and its local branches, especially in the Balkans.

The importance of predation in benthic stream communities

There has been considerable debate whether or not predators has any significant effects on prey densities in streams. This thesis examines the importance of predation in stream communities. I have conducted both field and laboratory studies where I have studied how both vertebrate and invertebrate predators affects benthic prey. Generally, predators have been found to have strong negative effects

Functional organization of spinal nociceptive pathways: evidence for a modular organization of spinal nociceptive reflex systems

The functional organization of the hindlimb withdrawal reflex system was studied in the rat. For the reflex pathway to each muscle, a "mirror-image" relationship was found between the spatial distribution of sensitivity within its cutaneous receptive field and the pattern of cutaneous unloading ensuing on muscle contraction. Thus, the withdrawal movement pattern ensuing on contraction in a muscle

Ethylene dissociation on flat and stepped Ni(111): A combined STM and DFT study

The dissociative adsorption of ethylene (C2H4) on Ni(1 1 1) was studied by scanning tunneling microscopy (STM) and density functional theory (DFT) calculations. The STM studies reveal that ethylene decomposes exclusively at the step edges at room temperature. However, the step edge sites are poisoned by the reaction products and thus only a small brim of decomposed ethylene is formed. At 500 K dec

Atomic Influences in Stellar Spectroscopy

Popular Abstract in Swedish Stjärnor samt andra astronomiska objekt är belägna på väldigt stora avstånd från oss, vilket innebär att de vid första anblick verkar svåra att undersöka. Den enda pålitliga informationskällan om deras funktion och utveckling är det ljus som de utsänder, d.v.s. deras spektrum. Hur kan man då erhålla någon användbar information om dessa avlägsna objekt genom att endast uThis thesis is a description of how knowledge of atomic physics can be used in a stellar spectrum analysis. Stellar investigations are spectroscopically performed based on wavelengths, intensities and spectral line structure. Properties such as isotopic shifts, hyperfine structure, Zeeman effect, line blending and spectral line broadening are investigated in stellar spectra to improve results of a

Bilder av småstaden - om estetisk värdering av en stadstyp; Images of the Small Town - on Aesthetic Evaluation of a Townscape

The thesis takes its starting-point in the last years' growing interests in the small town as an architectural concept. Pre-industrial small towns are used as visual and structural models for very attractive new settlements in Sweden. However, architects and other actors within the cultural sphere question the adequacy of using old models for new buildings. The thesis' overarching question is: Wha
