The intensity of a fire is an important factor determining the recovery of soil microorganisms after a forest fire, since it can alter the quality and quantity of carbon sources. Recovery of the microbial community was studied in a Mediterranean pine forest soil subjected to different temperatures to simulate the short-term effects of fire intensity on bacterial and fungal growth, estimated using

Preeclampsia is one of the most serious pregnancy-related diseases and clinically manifests as hypertension and proteinuria after 20 gestational weeks. The worldwide prevalence is 3-8% of pregnancies, making it the most common cause of maternal and fetal morbidity and mortality. Preeclampsia lacks an effective therapy, and the only "cure" is delivery. We have previously shown that increased synthe

Popular Abstract in Swedish Skolämnet livskunskap har vuxit fram i svenska skolor under det senaste decenniet, ofta utifrån en ambition att främja hälsa och att konkretisera skolans värdegrundsarbete. Avhandlingen belyser hur livskunskap växer fram och definieras som ett skolämne i nationella och kommunal dokument, och organiseras i lokal skolpraktik. Studien, som har en kombinerad barndomssocioloThe aim of this thesis is to understand and cast light over how the school subject Life Competence Education (Sw. Livskunskap) is developing in the Swedish school context. In focus of the study is how this school subject is defined and organized by actors (i.e. politicians, national governmental institutes, local governmental authorities, teachers and children in compulsory schools) in the differe

One of the big obstacles for understanding the nervous system is its inherent complexity. It poses problems when interpreting both experimental and theoretical studies since we are currently forced to consider only reduced variants of the actual circuitry of the brain. Since there exist problems that do not appear until a system is sufficiently complex, there are no guarantees that the results ste

Organised by, National Institute for Working Life, Solna, Sweden in co-operation with National Institute of Occupational Safety and Health, Cincinnati, USA; National Institute of Occupational Health, Moscow, Russia; National Institute of Public Health, Tokyo, Japan, unde

Attention deficit/hyperactivity disorder (ADHD) is characterized by inattention, impulsivity, and motor hyperactivity. Several lines of research support a crucial role for the dopamine transporter (DAT) gene in this psychiatric disease. Consistently, the most commonly prescribed medications in ADHD treatment are stimulant drugs, known to preferentially act on DAT. Recently, a knock-in mouse [DAT-c

Due to increased awareness of climate change and higher energy costs, well‐insulated buildings have become more common. Furthermore, the interests of using wood in building to produce more carbon dioxide‐efficient houses have increased. However, thicker thermal insulation in walls increases the risk of high relative humidity levels and the risk of mould‐related damage in Wood frame houses. In orde

When biomass is used to produce fuels and green products by thermochemical conversion, the ability to handle or remove the fine particle phase in the product gas is crucial. The product gas from biomass gasification contains relatively volatile organic compounds (“tar”) condensed on nonvolatile cores of, for example, aggregated soot particles and char. The problems are, for example, that particles

Popular Abstract in Swedish Pappersbrott i planet har studerats med hjälp av den kohesiva sprick modellen ur ett experimentellt såväl som ur ett teoretiskt perspektiv. Brott i en pappersremsa erhålls när remsan i en provmaskin belastas till sin maximala bärlast. Om remsan är tillräckligt kort fås en stabil nedåtgående last-förlängnigs kurva efter det att max lasten är nådd. Det visade sig att denThe in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. It is observed that under uniaxial in-plane tensile tests, the evolution of the failure is stable and the damage of the paper strip is localized into a narrow zone

Popular Abstract in Swedish Sammanfattning Nukleotider påverkar kärltensionen och hjärtats slagkraft. Då ett blodkärl skadas, då blod koagulerar eller vid minskad syretillförsel till hjärtat frisätts en mängd ämnen från kärlväggar och blodceller. Bland annat frisätts så kallade nukleotider (ATP, ADP, UTP och UDP). Nukleotider har tidigare visats ha viktiga funktioner inuti cellen vid energiomsättnThe aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes. We demonstrate that ATP, ADP, UTP and UDP induce vascular rel

Popular Abstract in Swedish Hemofili (blödarsjuka) A och B, är X-kromosomalt, recessivt, nedärvda sjukdomar som orsakas av brist på eller avsaknad av koagulationsfaktor VIII respektive IX i blodet (FVIII och FIX). Sjukdomen drabbar män och överförs till nästa generation av kvinnliga bärare, som vanligtvis inte själva har några blödnings-symtom. Blödarsjuka ger redan tidigt i livet upphov till blöd

Popular Abstract in Swedish Immunologi står för läran om immunförsvaret. Under evolutionens gång har vårt immunförsvar utvecklats med oss, och skyddar oss effektivt mot många olika virus, bakterier, parasiter och oönskade främmande ämnen. Hos ryggradsdjuren har immunförsvaret utvecklats till ett komplext system där flera olika specialiserade celler och molekyler samverkar för att uppnå ett optimal
