Brännässlor–inte bara ogräs

Stinging nettles are not always appreciated, but have been used for spinningyarn and weaving since the Bronze Age, and have also been much used in folk medicine. They are used as food for caterpillars of several of our most beloved butterflies, but area lso victims of an interesting parasitic plant, the dodder.And they can be used to make a delicate soup!

Concentration Bounds for Single Parameter Adaptive Control

The purpose of this paper is to analyse transient dynamics in adaptive control using statistical concentration bounds. For maximal clarity, the study is limited to a linear first order system with a single uncertain parameter. Two types of bounds are given: First we prove probabilistic bounds on the parameter estimation error as a function of time. In particular, we prove that the estimation error

Heat transfer correlations for jet impingement boiling over micro-pin-finned surface

Heat transfer performance of submerged jet impingement boiling over staggered micro-pin-finned surfaces was investigated using air-dissolved FC-72. The dimension of the silicon chips is 10 × 10 × 0.5 mm3 (length × width × thickness) on staggered micro-pin-fins with four dimensions of 30 × 30 × 60 μm3, 50 × 50 × 60 μm3, 30 × 30 × 120 μm3 and 50 × 50 × 120 μm3 (width × thickness × height, named S-PF

Smoking, disease characteristics and serum cytokine levels in patients with primary Sjögren's syndrome

Smoking affects several disease processes. Epidemiological studies have previously found a negative association between primary Sjögren's syndrome (pSS) and smoking. The aim of this study was to examine whether markers of disease activity and cytokine expression in pSS patients differ between ever and never smokers. Fifty-one consecutive pSS patients and 33 population controls were included in the

Brandskyddsvärdering av flerbostadshus BSV-FB : Utveckling av metod för säkerhetsindex

A fire safety assessment method for multi-family buildings has been developed. The method is a scoring method and 19 parameters are assessed in order to determine the building fire safety level. Each parameter has its own weight for the total fire safety and the parameter weights are determined based on judgement in two expert groups. The expert groups have performed the weighting assessment indep

Prevalence of G6PD deficiency and associated haematological parameters in children from Botswana

Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is commonly seen in malaria endemic areas as it is known to confer a selective advantage against malaria. Recently, we reported a high proportion of asymptomatic reservoir of Plasmodium vivax in Botswana, that calls for intervention with primaquine to achieve radical cure of vivax malaria. Considering that individuals with this enzyme deficiency

Localized carbon deposition in solid oxide electrolysis cells studied by multiphysics modeling

Solid oxide electrochemical cells (SOCs) can store electrical energy in the form of chemical fuels with high efficiency by electrolysis of CO2 and H2O. However, achieving commercially relevant lifetime is hindered by degradation mechanisms such as carbon deposition, which can even destroy the cell especially during electrolysis where carbon formation is electrochemically driven at the electrode-el

Is familial risk for depression confounded by individual and familial socioeconomic factors and neighborhood environmental factors? A 7-year follow-up study in Sweden

Family history of depression is an important risk factor for depression. The aim of this study was to examine whether the effect of family history of depression is confounded by individual and familial socioeconomic factors (i.e., country of origin, educational attainment, family income and mobility) and neighborhood environmental factors (i.e., neighborhood deprivation and neighborhood social cap

Formation of NO and NH in NH3-doped CH4 + N2 + O2 flame : Experiments and modelling

Co-combustion of 5200 ppm NH3 with a stoichiometric, atmospheric pressure, CH4 + N2 + O2 flame has been investigated with experiments and kinetic modelling. Profiles of the amidogen (NH) radical and nitric oxide (NO) have been measured using laser-induced fluorescence, the latter being quantitatively determined. Temperature profiles were measured using Rayleigh scattering and thermocouple, the non

Binge eating and other eating-related problems in adolescents undergoing gastric bypass : results from a Swedish nationwide study (AMOS)

Bariatric surgery is established as a treatment option for adolescents with severe obesity. Little is known about binge eating (BE) and other eating-related problems in adolescents undergoing bariatric surgery. BE, emotional eating, uncontrolled eating, and cognitive restraint were assessed at baseline, and one and two years after gastric bypass using questionnaires in 82 adolescents (mean age 16.

Developing defined substrates for stem cell culture and differentiation

Over the past few decades, a variety of different reagents for stem cell maintenance and differentiation have been commercialized. These reagents share a common goal in facilitating the manufacture of products suitable for cell therapy while reducing the amount of non-defined components. Lessons from developmental biology have identified signalling molecules that can guide the differentiation proc

Mortality and causes of death among people who inject amphetamine : A long-term follow-up cohort study from a needle exchange program in Sweden

Background: Abuse of amphetamines is a worldwide problem with around 34 million users, and amphetamine is commonly used by people who inject drugs (PWID). Despite this, there is relatively little research on mortality and cause of death among people who use amphetamines primarily. The present study aimed to examine mortality and causes of death among people who inject amphetamine, and compare thes
