A comparison of alternative modelling approaches to evaluate the European forest carbon fluxes

The European forest carbon balance studied by various methods shows different results. We compared the regional and national net primary production (NPP) estimated by the forest inventory-based model EFISCEN and the climate-based terrestrial ecosystem models (TEMs: BIOME-BGC, ORCHIDEE, and JULES), and single forests NPP derived from the international network of eddy-covariance towers (FLUXNET). In

Electron transport study of a lateral InGaAs quantum dot

We report on fabrication and electron transport measurements of lateral InGaAs quantum dots defined by wet chemical etching. The tunneling barriers and dot potential are tuned using both etching-defined in-plane gates and a local top gate. Transport measurements performed at low temperature show Coulomb diamonds with excited states in the bias spectroscopy indicating the effects of quantum confine

Prenatal Phthalate Exposures and Anogenital Distance in Swedish Boys

BACKGROUND: Phthalates are used as plasticizers in soft polyvinyl chloride (PVC) and in a large number of consumer products. Because of reported health risks, diisononyl phthalate (DiNP) has been introduced as a replacement for di(2-ethylhexyl) phthalate (DEHP) in soft PVC. This raises concerns because animal data suggest that DiNP may have antiandrogenic properties similar to those of DEHP. The a

Mitral Valve Surgery: Effects on Cardiac Reverse Remodeling, Hemodynamics, and Clinical Outcome

Popular Abstract in Swedish Mitralisklaffen (lat. valva mitralis; valva bicuspidalis) är den klaff i hjärtat som finns mellan vänster förmak och vänster kammare. Till utseendet liknar klaffen påvens huvudbonad, mitra, varifrån namnet härstämmar. Mitralisklaffen består av två segelliknande flikar (klaffblad) med en upphängningsapparat som fäster sig i vänster-kammarens vägg. När vänster kammare konNormalization of life expectancy after mitral valve surgery is highly dependent on early diagnosis and referral for surgical treatment. Among cases treated surgically, the majority (60–70%) have a degenerative etiology, which is also easiest to repair. The general aim of this thesis was to bring research on treatment of degenerative mitral regurgitation a step further in order to improve clinical

Histology of adipose tissue inflammation in Dercum's disease, obesity and normal weight controls: a case control study.

BACKGROUND: Dercum's disease (DD) is characterised by obesity and chronic pain (> 3 months) in the adipose tissue. The pathogenesis of DD is unknown, but inflammatory components have been proposed. In previous reports and studies, an inconsistent picture of the histological appearance of the adipose tissue in DD has been described. The aim of this investigation was to examine the histological app

Ankle-foot orthoses in children with cerebral palsy: a cross sectional population based study of 2200 children.

Ankle-foot orthosis (AFO) is the most frequently used type of orthosis in children with cerebral palsy (CP). AFOs are designed either to improve function or to prevent or treat muscle contractures. The purpose of the present study was to analyse the use of, the indications for, and the outcome of using AFO, relative to age and gross motor function in a total population of children with cerebral pa

Effect of lactobacilli on paracellular permeability in the gut.

Paracellular permeability is determined by the complex structures of junctions that are located between the epithelial cells. Already in 1996, it was shown that the human probiotic strain Lactobacillus plantarum 299v and the rat-originating strain Lactobacillus reuteri R2LC could reduce this permeability in a methotrexate-induced colitis model in the rat. Subsequently, many animal models and cell

Genetics of Type 2 Diabetes and Metabolic Syndrome: From Genome Wide Linkage Scan and Candidate Genes to Genome Wide Association Studies

Type 2 diabetes (T2D) and metabolic syndrome (MetS) are major health problems associated with cardiovascular disease. Both diseases are influenced by a combination of genetic and environmental factors. The aim of this thesis was to identify genetic risk factors for T2D, particularly T2D associated with obesity, and for MetS. To achieve this goal, we 1) followed-up a region linked to obese T2D in a

Strangeness production at low Q(2) in deep-inelastic ep scattering at HERA

The production of neutral strange hadrons is investigated using deep-inelastic scattering events measured with the H1 detector at HERA. The measurements are made in the phase space defined by the negative four-momentum transfer squared of the photon 2 < Q(2) < 100 GeV2 and the inelasticity 0.1 < y < 0.6. The K-s(0) s and Lambda((Lambda) over bar) production cross sections and their ratios are dete

Severe Streptococcus pyogenes disease in Europe; epidemiology and clinical manifestations

Streptococcus pyogenes, gives rise from mild skin infections and pharyngitis, to life threatening infections like bacteraemia, cellulitis, puerperal sepsis, meningitis, pneumonia, necrotizing fasciitis (NF), and streptococcal toxic-like shock syndrome (STSS), or nonsuppurative sequelae, rheumatic fever and glomerulonephritis. In 2002, the first multinational network for invasive GAS disease survei

Creating creative environments

There is empirical evidence indicating that trust in research is decreasing. If distrust is justified, this is a good thing; if not, it is a cause of concern. A basic question concerns the reasons for, ant the causes of, distrust. Which are they, what do they mean, and how reliable are they? The papers and presentations in this volume focus on external and internal factors contributing to distrus

Att förklara människan : Diskurser i populärvetenskapliga TV-program

The principle aim of the study is to describe, analyze and problemize the ways in which television science documentaries (within a public service context) discursively represent scientific theories, research results and conclusions about the origins of human nature and the causes of human behavior. The study covers 25 programs broadcasted by SVT and UR during a period of four years, 2002-2005, and

Rational design of HIV vaccines and microbicides: report of the EUROPRISE network annual conference 2010

Novel, exciting intervention strategies to prevent infection with HIV have been tested in the past year, and the field is rapidly evolving. EUROPRISE is a network of excellence sponsored by the European Commission and concerned with a wide range of activities including integrated developmental research on HIV vaccines and microbicides from discovery to early clinical trials. A central and timely t

Front- and backstage in social media

Oversharing of information about one's private life or the private lives of others appears to be an oft-noted phenomenon in the context of social media. This paper aims at answering the following question: What is it in social media as media and in the communicative situation of the person using them that facilitate oversharing of private information? A comparative analysis of face-to-face interac

The Anatomy and Physics of Z(DR) Columns: Investigating a Polarimetric Radar Signature with a Spectral Bin Microphysical Model

Polarimetric radar observations of deep convective storms frequently reveal columnar enhancements of differential reflectivity Z(DR). Such "Z(DR) columns" can extend upward more than 3 km above the environmental 0 C level, indicative of supercooled liquid drops being lofted by the updraft. Previous observational and modeling studies of Z(DR) columns are reviewed. To address remaining questions, th

On the sensitivity of rotational CARS N-2 thermometry to the Herman-Wallis factor

Purely rotational spectral signals of coherent anti-Stokes Raman scattering (CARS) from nitrogen molecules are studied as a function of the vibration-rotation interaction that weakens the rigid rotor approximation under which the dominant terms of the Raman cross section are calculated. The effect of the vibration-rotation interaction is quantified by means of the Herman-Wallis (HW) factor, and di

Internal and External Knowledge and Introduction of Export Varieties

Firms in local industries maintain their capability to generate new export varieties by simultaneously exploiting internal and external knowledge resources. The paper introduces the notion variety triplet' to distinguish individual export varieties, where a triplet is a unique combination of a firm, a product code and a destination country. For each date, the set of variety triplets in each local
