Popular Abstract in Swedish Tre av huvudets blodkärlsregioner - hjärnans, den h rda hjärnhinnans och tinningens puls dror, har undersökts med avseende p förekomst av nerver inneh llande signalsubstanser som kallas neuropeptider. Tv av dessa är substans P (SP) och kalcitonin gen-relaterad peptid (CGRP) vilka finns i nerver som förmedlar känselupplevelser, till exempel smärta. Andra är neuropeptid YThe sensory neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) are present in human cerebral, meningeal and temporal arteries, as are peptides associated with the sympathetic (neuropeptide Y, NPY) and parasympathetic (vasoactive intestinal peptide, VIP) nervous system. NPY is a vasoconstrictor in cerebral and meningeal arteries and potentiates noradrenaline (NA) as a vasocon

1. INTRODUCTION Geographers at the University of Lund have been active in research on desertification/ land degradation and environmental change monitoring of African drylands since the mid 1970’ies and of Asian drylands since the beginning of the 1990’ies. The results obtained so far do not confirm the concept of desertification as a mainly man made phenomena but indicate that the importance of c

Popular Abstract in English The thesis that you are reading at this moment was printed using climate compensated paper, a sign that consciously or not you are contributing somehow to control the current environmental issues in our planet. It would not be nice if every single article used in your daily life contains information about how environmentally friendly that product is? We have to think “bOxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage. This has called

The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde

Three titania polymorphs, anatase, rutile, and TiO2(B), were used as supports for vanadia. Catalysts with nominal loadings corresponding to 1.5 and 5 theoretical layers were prepared. True monolayer samples were obtained by NH3(aq)-treatment of the samples with 5 nominal vanadia layers. Prepared catalysts were characterized by chemical analysis, ESR, and high-resolution electron microscopy. It was

Popular Abstract in English The food we consume is hardly, if ever, sterile. From fresh produce to processed products, foods harbor one or more types of microorganisms. The presence of some ‘beneficial’ microorganisms is desirable in food production, because they contribute to the characteristics of the final product, as, for example, in the production of wine, beer or cheese. In other cases, micrControl of the dissemination of pathogens in the food production chain is an on-going process with new challenges emerging as pathogenic bacteria evolve and express enhanced virulence characteristics. Staphylococcus aureus and Listeria monocytogenes are two notorious pathogens responsible for staphylococcal food poisoning (SFP) and listeriosis: a foodborne intoxication and an infectious disease re

The aim of this work is to propose a framework for providing QoS routing in MANETs. The proposed framework uses local information of nodes such as node's speed, buffer, and power to select path for routing. Deploying these information, more stable paths are selected and hence QoS routing parameter could be satisfied. Moreover, routing performance has been improved, especially in terms of end-to-en

A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NO_X, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, ha

Popular Abstract in Swedish Cancer är på cellnivå en genetisk sjukdom, i det avseendet att typiska egenskaper för cancerceller, t ex okontrollerad celldelning samt abnorm känslighet för yttre regulatoriska signaler, uppkommer genom förvärvade och ibland ärftliga förändringar, s k mutationer, i cellens arvsmassa. Hur mutationerna uppstår är bara till viss del känt. Somliga förändringar beror på strAcquired genetic alterations, of which many are visible on the chromosome level, are believed to be necessary for tumorigenesis, and most tumors display characteristic patterns of recurrent structural and numerical aberrations. However, two of the most frequently occurring chromosome mutations in malignant and benign solid tumors, i.e., trisomy 7 and rearrangements of 12q13-15, have recently been

Popular Abstract in Swedish Intensifieringen av jordbruket sedan 1950-talet har lett till en ökad matproduktion men också orsakat miljöproblem så som förlust av biologisk mångfald, jorderosion, övergödning, ökade utsläpp av växthusgaser samt föroreningar av bekämpningsmedel. Det är därför nödvändigt att utveckla ett mer hållbart jordbruk samtidigt som vi upprätthåller den globala matförsörjningen Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. Hence we need to replace pesticides with management that promote organisms that suppress pest population.

Popular Abstract in Swedish Närmare 30.000 svenskar drabbas årligen av stroke (slaganfall). I ungefär 85 % av fallen är orsaken en blodpropp i ett av hjärnans kärl s.k. hjärninfarkt. En avstängning av blodflödet orsakar en snabbt insättande förlust av funktionen i det drabbade området, t.ex. halvsidig förlamning, bortfall av delar av synfältet liksom störning av olika högre hjärnfunktioner såsom mAbstract Stroke is the third leading cause of death in the western world, and the number one cause of disability. 85% of all strokes are ischemic. Most stroke survivors will experience recovery of function. The mechanisms behind this improvement are partly unknown, but may involve elements of both compensation and restoration. Exposure to an enriched environment (EE) that stimulates social interac
