Climate Change and UV-B Impacts on Arctic Tundra and Polar Desert Ecosystems: Key Findings and Extended Summaries

The Arctic has become an important region in which to assess the impacts of current climate variability and amplification of projected global warming. This is because i) the Arctic has experienced considerable warming in recent decades (an average of about 3°C and between 4° and 5°C over much of the landmass); i) climate projections suggest a continuation of the warming trend with an increase in me

Citizen Participation and Institutional Coordination: an examination of public transport and land use planning in Dar-es-Salaam, Tanzania.

This project is a continuation of the research project: Public transport in Dar-es-Salaam, Tanzania; institutional challenges and opportunities for a sustainable transport system carried out from 2003 to 2004. This study analyses mechanisms, forms for involvement and participation in planning for public transport. Questions asked are: How can participatory transport planning involving the supplier

Haplotype structures and large-scale association testing of the 5 ' AMP-activated protein kinase genes PRK4A2, PRKAB1, and PRK4B1 with type 2 diabetes

AMP-activated protein kinase (AMPK) is a key molecular regulator of cellular metabolism, and its activity is induced by both metformin and thiazolidinedione antidiabetic medications. It has therefore been proposed both as a putative agent in the pathophysiology of type 2 diabetes and as a valid target for therapeutic intervention. Thus, the genes that encode the various AMPK subunits are intriguin

Norian SRS versus functional treatment in redisplaced distal radial fractures: A randomized study in 20 patients

We compared the use of Norian SRS, an injectable calcium phosphate bone cement, with functional treatment of redisplaced distal radial fractures in a prospective randomized study of 20 patients. The redisplaced fractures were either rereduced and stabilized by Norian SRS, or the displaced position was accepted and was not rereduced. All wrists were immobilized in a short-arm dorsal splint for 1 we

Aerosol elemental concentrations in the tropopause region from intercontinental flights with the Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrument Container (CARIBIC) platform

This study with the Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrument Container (CARIBIC) platform investigates the aerosol elemental concentrations at 9-11 km altitude in the northern hemisphere. Measurements from 31 intercontinental flights over a 2-year period between Germany and Sri Lanka/Maldives in the Indian Ocean are presented. Aerosol samples were collected

Pravastatin treatment increases collagen content and decreases lipid content, inflammation, metalloproteinases, and cell death in human carotid plaques - Implications for plaque stabilization

Background--The clinical benefits of lipid lowering with statins are attributed to changes in plaque composition leading to lesion stability, but supporting clinical data from human studies are lacking. Therefore, we investigated the effect of 3 months of pravastatin treatment on composition of human carotid plaques removed during carotid endarterectomy. Methods and Results--Consecutive patients w

Unusual vascular responses in the umbilical artery, mediated by endothelin-like receptors

Popular Abstract in Swedish Kontrollmekanismerna rörande blodcirkulationen i den mänskliga fetoplacentära enheten är fortfarande inte fullständigt kända, trots genomgripande undersökningar. Det är dock känt att den är viktig för att kunna bibehålla en normal graviditet och för att kunna frambrigna ett friskt nyfött barn. Om kontrollen brister kan utgången försämras i form av tillstånd såsom preeklIn this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery. ET-1 induced vasoconstriction wa

Språket i universum : Polhem och alfabetskonsten

The Swedish inventor Christopher Polhem had an idea of a universal language which occupied him for decades, i.e. a perfect language which can be spoken and understood by everyone, by the educated and non educated alike, and no matter where they come from. Polhem did a large number of sketches for such a universal language, among others a manuscript concerning a lunar language, which was completely

Determination of cotinine in urine using glass capillary gas chromatography and selective detection, with special reference to the biological monitoring of passive smoking

A capillary gas chromatographic (GC) method using selected-ion monitoring (SIM) was developed for the analysis of cotinine (C.A.S. No. 486-56-6) in human urine. The method is based on basic extraction of cotinine from 2 ml of urine into dichloromethane. After evaporation of the dichloromethane solution to dryness, 100 microliters of toluene were added, prior to GC-mass spectrometric (MS) analysis.

Lean-DeNO(x) titania based monolithic catalysts

The activity of titania based copper and platinum monolithic catalysts in the reduction of nitrogen oxides was studied with exhaust gases from a Diesel engine injecting fuel as reductant. Combining both catalysts, a two-stage system was designed, studying the influence of the copper catalysts composition on its performance with synthetic gas mixtures. The influence of reactants concentration and o

The elusiveness of Protestantism: The last expatriations for "apostasy" from the Church of Sweden (1858) in a European perspective

By studying the responses to the last expulsion for "apostasy" from the Swedish National Church in 1858, this article examines how an international Protestant identity was constructed in mid-nineteenth-century Europe. It is the argument of this study that a comprehensive identity - including both evangelicals and theological progressives - could be built around the notion of religious liberty. The
