A global Canopy Water Content product from AVHRR/Metop

Spatially and temporally explicit canopy water content (CWC) data are important for monitoring vegetation status, and constitute essential information for studying ecosystem-climate interactions. Despite many efforts there is currently no operational CWC product available to users. In the context of the Satellite Application Facility for Land Surface Analysis (LSA-SAF), we have developed an algoriSpatially and temporally explicit canopy water content (CWC) data are important for monitoring vegetationstatus, and constitute essential information for studying ecosystem-climate interactions.

Evaluation of the LSA-SAF Gross Primary Production product derived from SEVIRI/MSG data (MGPP)

The objective of this study is to describe a completely new 10-day gross primary production (GPP) product (MGPP LSA-411) based on data from the geostationary SEVIRI/MSG satellite within the LSA SAF (Land Surface Analysis SAF) as part of the SAF (Satellite Application Facility) network of EUMETSAT.

Modelling land–atmosphere daily exchanges of NO, NH3, and CO2 in a semi-arid grazed ecosystem in Senegal

Three different models (STEP–GENDEC–NOflux, Zhang2010, and Surfatm) are used to simulateNO, CO2, and NH3 fluxes at the daily scale for 2 years(2012–2013) in a semi-arid grazed ecosystem at Dahra(152401000 N, 152505600W, Senegal, Sahel). Model resultsare evaluated against experimental results acquired duringthree field campaigns.

Model results are evaluated against experimental results acquired during three field campaigns. At the end of the dry season, when the first rains re-wet the

Mortality in first- and second-generation immigrants to Sweden diagnosed with type 2 diabetes : a 10 year nationwide cohort study

Aims/hypothesis: Non-Western immigrants to Europe are at high risk for type 2 diabetes. In this nationwide study including incident cases of type 2 diabetes, the aim was to compare all-cause mortality (ACM) and cause-specific mortality (CSM) rates in first- and second-generation immigrants with native Swedes. Methods: People living in Sweden diagnosed with new-onset pharmacologically treated type

Management of Acute Mesenteric Venous Thrombosis : A Systematic Review of Contemporary Studies

BACKGROUND AND AIMS: Acute mesenteric venous thrombosis accounts for up to 20% of all patients with acute mesenteric ischemia in high-income countries. Acute mesenteric venous thrombosis is nowadays relatively more often diagnosed with intravenous contrast-enhanced computed tomography in the portal phase than at explorative laparotomy No high-quality comparative studies between anticoagulation alo

Atomistic investigation of functionalized polyethylene-alumina interfacial strength and tensile behaviour

We study the adhesion and tensile behaviour of bi-layer interfaces comprising polyethylene, doped with carbonyl and hydroxyl functional groups emanating from ozone treatment, and - by means of density functional theory and classical atomistic modelling. The results show that the deformations are localized within the polymer and comprise chain slip, disentanglement and detachment from the substrate

Making ethics teaching more effective with a three step model

In this study, the impacts of two different “methods” for teaching ethics as part of the religious education in the Swedish upper secondary school were compared by means of a non-randomized controlled trial in two parts, involving 542 students. The question was which “method” had the greatest capacity to generate long-term ethical awareness in the students. The intervention condition consisted of

Kartläggning av bebyggelse med risk för höga temperaturer : Metodbeskrivning av GIS-verktyg utifrån marktäckning

Värmeböljor är den klimateffekt som väntas få störst påverkan på hälsan i Europa, och värmeböljor förväntas bli vanligare, intensivare och mer långvariga iframtiden.I tätorter skapas ett lokalt klimat som gör att befolkningen där kan bli mer exponerad för värme än i glesare bebyggda områden. Det gäller särskilt tätbebyggda områden med hög andel hårdgjorda ytor och lite vegetation. I sådana områden

Chronic inflammation in the etiology of disease across the life span

Although intermittent increases in inflammation are critical for survival during physical injury and infection, recent research has revealed that certain social, environmental and lifestyle factors can promote systemic chronic inflammation (SCI) that can, in turn, lead to several diseases that collectively represent the leading causes of disability and mortality worldwide, such as cardiovascular d

The evolutionary ecology of plant reproductive diversity and floral signals : Mating system and floral scent in Arabis alpina

Flowering plants display an extraordinary floral- and reproductive diversity. Variation in the size, shape, colour and scent of flowers, and in systems and strategies of mating, is ubiquitous in comparisons of different species, but also exists among different conspecific populations. Diversity in these characters is central to the evolution of flowering plants and the formation of new species. In

Successful aging : Insights from proteome analyses of healthy centenarians

Healthy aging depends on a complex gene-environment network that is ultimately reflected in the expression of different proteins. We aimed to perform a comparative analysis of the plasma proteome of healthy centenarians (n=9, 5 women, age range 100-103 years) with a notably preserved ambulatory capacity (as a paradigm of 'successful' aging), and control individuals who died from a major age-relate
