We have shown recently that PrkC, which is involved in developmental processes in Bacillus subtilis, is a Ser/Thr kinase with features of the receptor kinase family of eukaryotic Hanks kinases. In this study, we expressed and purified from Escherichia coli the cytoplasmic domain of PrkC containing the kinase and a short juxtamembrane region. This fragment, which we designate PrkCc, undergoes autop
Popular Abstract in Swedish FN:s konferens om miljö och utveckling i Rio 1992 blev startpunkten för det lokala Agenda 21 arbetet och många svenska kommuner påbörjade lokala Agenda 21 processer under 1993.

Popular Abstract in Swedish Melatonin är ett hormon som produceras i, och frisätts från pinealorganet hos ryggradsdjur. Melatoninets viktigaste uppgift är att till hjärnan förmedla signalen om nattens längd, d.v.s vilken årstid det är. Produktionen och frisläppningen sker rytmiskt med den högsta nivån under natten. Melatoninet transporteras ut i kroppen via blodet och binder till särskilda mottagaMelatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. It has previously been suggested that functional interaction exists between central binding sites for GABA/benzodiazepines (GABAA/bzd receptors) and melatonin in the central nervous system, and that GABA a
It is well established that floral odours play a significant role in the nectar foraging behaviour in Lepidoptera and other insect orders. Floral odour may elicit searching, alighting and feeding behaviours alone or in concert with visual stimuli. The goal of the present project was to investigate attractiveness of different species of flowers to the silver Y moth, to identify constituents of vola
Popular Abstract in Swedish Järn har den kemiska beteckningen Fe från latinskans ferrum. Det är det fjärde vanligaste ämnet i världen och utgör ca en femtedel av jordskorpan. Trots det kan både djur och växter ha järnbrist. Hur kan detta vara möjligt? Problemet är egentligen inte förekomsten av järn utan att järnet som vi och alla andra organismer behöver har oxidationstillståndet Fe(II) medan detIt is of vital importance to understand the systems for iron metabolism and this thesis contributes to this by providing insights into the structure and function of the acquisition and homeostasis of iron. The two proteins that have been primarily investigated are a ferric reductase from Arabidopsis thaliana called FRO2 and a mitochondrial iron chaperone from Saccharomyces cerevisiae called fratax
Popular Abstract in Swedish Så gott som alla metaller reagerar vid normala omständigheter med syret i luften och oxideras, vilket förändrar materialets egenskaper. T.ex. rostar järn efter hand, något som alla bilägare är bittert medvetna om. Oxider behöver dock inte vara negativa, utan kan även fungera som barriärer mot fortsatt korrosion, isolerande skikt i mikroelektronikkomponenter m.m. FöljaktThe oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scannin
Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins. Lipids, which are present in many starches and products, play an imp
Geographic accessibility to services is important. Having a grocery store and a school nearby are important living conditions and having a rescue station close by could be a life-saver. Costs for transportation are high and are predicted to increase, new environmental demands are being imposed on transportation and rationalizations are centralizing public and commercial services. These facts make
Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. A rather recent approach for modelling extreme events is the so called peak over threshold (POT) method. The generalised Pareto distribution (GPD) is
The fundamental equations for the theoretical treatment of wood during the process of pyrolysis are presented in Chapter 1. Expressions which must be specially introduced for combustible materials are those which describe the pyrolyctic reaction and reactions at the surface of the material. The reactions are assumed t o conform to first order Arrhenius functions. The treatment also includes the va
Background: Non-linearities in observed log-ratios of gene expressions, also known as intensity dependent log-ratios, can often be accounted for by global biases in the two channels being compared. Any step in a microarray process may introduce such offsets and in this article we study the biases introduced by the microarray scanner and the image analysis software. Results: By scanning the same sp
Popular Abstract in Swedish Mer än 75 % av energianvändningen i världen kommer idag från förbränning av fossila bränslen, biobränslen och avfall. Trots att alternativa energikällor är på framfart kommer förbränning stå för den största andelen av världens energianvändning även de kommande decennierna. Tyvärr medför förbränning flera negativa konsekvenser, såsom ökad koldioxidhalt i atmosfären och uLaser-induced incandescence, LII, is a laser-diagnostic technique that can be used to measure the volume fraction and the sizes of soot particles suspended in a gas, such as within a combustion process or in its exhausts. The technique is based on the facts that the time-decay of the radiation from laser-heated soot particles is directly related to the particle size in the probed volume, and that
This thesis consists of four self-contained essays on different conflicts shaping local government policy. The first essay examines how population aging affects the generosity of public long-term care. Aging may directly affect long-term care policy as the elderly become a more important voter group. However, concerns for other citizens may dampen the political importance of the elderly. Fixed e
Understanding of intermolecular interactions are important in order to gain insight into a large number of physical processes. This thesis concerns itself with theoretical modelling of such interactions. In particular there is a focus one of interaction contributions called polarization. This interaction is sometimes ignored, but is a real and often important effect. For a model to be able to desc
Managing material flows along a supply chain is a complex matter involving a great many interfaces both between activities and between actors. Integration of material flows may smooth the interfaces and thus also the potential errors and delays in the material flows. The potential to obtain such integration is facilitated by recent developments in identification technologies, particularly RFID tec

Popular Abstract in Swedish Skador på skelettet kan uppstå efter bl.a. olyckor, tumörkirurgi eller strålning. Ofta är sådana skador mycket handikappande då de påverkar kroppens funktion, stabilitet och utseende. Om benvävnad saknas eller måste bytas ut använder man sig idag av mikrokirurgiska metoder, där man flyttar kroppseget ben från ett ställe till ett annat. Tyvärr innebär detta att man skapaBone deficiencies, caused by malformations, trauma or adverse effects from medical treatments, are a clinical challenge and often associated with reduced physical function and quality of life. Autologeous bone grafts can be used to reconstruct skeletal defects, but the right size and quality of bone might not always be available and even so, donor-site morbidity might follow. A pre-fabricated or t
Popular Abstract in Swedish Stamceller är unika celler som har möjlighet att både förnya sig själva och ge upphov till en mängd mogna celler. Den ultimata stamcellen är det befruktade ägget, som är den cell som efter omfattande celldelning kommer att ge upphov till alla vävnader och celler i den färdigutvecklade kroppen. Dessa celler kallas därför pluripotenta. Även i den färdigutvecklade kroppen Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. Because of these features, HSCs are also the basis for bone marrow transplantation regimens for tr
Systems based on bag-of-words models from image features collected at maxima of sparse interest point operators have been used successfully for both computer visual object and action recognition tasks. While the sparse, interest-point based approach to recognition is not inconsistent with visual processing in biological systems that operate in 'saccade and fixate' regimes, the methodology and emph
