Popular Abstract in Swedish På senare tid har ett stort antal receptorer för extracellulära nukleotider (P2 receptorer) klonats vilka förmedlar en mängd effekter i hjärtkärlsystemet: inotropa effekter på hjärtat, trombocytaggregation, blodtrycksreglering, frisättning av endoteliala faktorer och stimulering av glatt muskeltillväxt. Redan idag står det klart att P2-receptorer är fysiologiskt och patP2 receptors mediate the actions of the extracellular nucleotides ATP, ADP, UTP and UDP regulating several physiological responses including cardiac function, vascular tone, smooth muscle cell (SMC) proliferation, platelet aggregation, and the release of endothelial factors. The aim of the present study was to investigate the mRNA and protein expression of P2 receptors in human SMCs, endothelial c

Growth theory predicts that poor countries will grow faster than rich countries. Yet, growth in developing countries has been consistently lower than growth in developed countries. The poor economic performance of developing countries coincides with both long-lasting and short-lived financial crises. In this paper, we analyze to what extent financial crises can explain low growth rates in developi

Intermetallic compounds are a distinct group of materials having attractive properties and wide applications. In the present work, the formation of intermetallic compounds from elemental components in Cu-Al, Ni-Al and Ni-Ti systems has been studied. Metallic powders were mixed in stoichiometric ratios corresponding to CuAl2, NiAl and NiTi. Calorimetric studies were made using compacted disks as we

Nematode-trapping fungi are soil-living organisms that have the ability to form infection structures, traps to capture nematodes. Many nematode species are parasites on plants and animals, which have resulted in an interest to use the nematode-trapping fungi as biological control agents. In order to understand more about the genomic diversity and evolution of parasitism among these fungi, several

The article examines four motifs/textual corpora in the Bible which have been referred to by those in favour of slavery: (1) the Exodus motif, (2) the Curse of Noah, (3) the parables of Jesus, and (4) the epistles of Paul. It is argued in the article that Christianity, with its canonized metaphors of slavery actually delayed the abolition of slavery in the 19th century by relativizing and idealizi

The prevalence of illnesses related to the modern diet and a more sedentary lifestyle has increased markedly over the last few decades. There is therefore a need for effective strategies to promote health and to reduce the prevalence of diet-related diseases. In this paper, we study the willingness to pay for a new concept, healthy canteen takeaways. In the analysis, we depart from a household pro

Popular Abstract in Swedish I denna avhandling presenteras en ny typ av röntgenkälla baserad på ett laser-producerat plasma. Röntgenstrålning alstras genom att fokusera laserpulser på ett strålmål. Energin i de enskilda laserpulserna blott är cirka 150 mJ, men tack vare den extremt korta pulstiden 100 fs (10E-13 s), blir laserns toppeffekt mer än 1 TW (10E12 W). Den extremt intensiva laserstrålninA 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

Presented at the Roundtable on NGOgraphy, American Anthropological Association Annual Meetings, Denver, 17 November 2015. This chapter describes the dialectic between fieldwork engagement

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

In this paper a method for reconnecting islanded distributed generation systems is presented. Islanding of a distributed generation system may result from a fault or malfunction of protective elements. The behavior of local voltage and frequency control in case of islanding is investigated. A method for reconnecting the distributed generation system and the behavior of voltage and frequency contro

The degradation of different polyethylenes, LDPE, LLDPE, and HDPE, with and without antioxidants and at different oxygen concentrations in the polymer granulates have been studied in extrusion coating processing. The degradation was followed by On Line Rheometry, Size Exclusion Chromatography, Surface Oxidation Index measurements, and GC-MS Chromatography. The degradations starts in the extruder w

In a world where distributed power generation and deregulation of energy markets are on everyone's agenda, the need for highly efficient power plants with short lead times is greater than ever. Although at present combined cycles provide a solution, development of ever more advanced machines to increase efficiency and lower the environmental impact has led to high maintenance costs and a decrease
