Popular Abstract in Swedish Under 1900-talet har jordbruket förändrats drastiskt. Från ett småskaliga lantbruk där åkrar, ängar och betesmarker avlöste varandra, och varje gård var beroende av att både odla mat och hålla djuren med foder, till ett allt mer specialiserat jordbruk där både de enskilda gårdarna och hela regioner specialiserat sig mot antingen spannmålsproduktion eller djurhållning. OAs a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is no

This study investigates the impact of childhood health on labor market outcomes. We used type 1 diabetes as an instrument of health because its cause is multifactorial and it is triggered by a complex combination of genetic and environmental components; its incidence is low and unforeseeable for the individual; and its onset may be considered an exogenous health shock. Using data from the Swedish

Popular Abstract in Swedish Njurarnas huvudsakliga funktion i kroppen är att rena blodet från slaggprodukter och reglera vätskebalansen. Hos patienter med nedsatt njurfunktion måste blodet renas på alternativa sätt. Antingen leds blodet ut via slangar till en maskin som renar blodet (hemodialys), eller används bukdialys, så kallad peritoneal dialys (PD). Vid PD häller patienten dialysvätska i bukhIn the present thesis, the quantitative role of active transport (transcytosis) in bulk transvascular protein movement in vivo was evaluated. Using chemical transcytosis inhibition (N-ethylmaleimide (NEM) and filipin), we were able to show that NEM actually increases endothelial permeability to macromolecules, probably as a result of unspecific toxic action on endothelial cells. Filipin, on the ot

The anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. These neuropil structures, c

Stress-laminated-timber (SLT) bridge decks are a valid alternative to conventional short- and medium-span bridges in terms of cost and performance. SLT decks are made from a number of planks or glulam beams positioned side by side and stressed together using high-strength steel bars. A concentrated load can therefore be distributed from the loaded beams onto adjacent beams due to the resisting fri

This article examines the conceptual framework of the social amplification of risk in relation to the social sciences framework of moral panic and the media violence debate in Britain. The paper will explore the symbolic use of 'risk' in relation to the alleged negative effects of media violence, and analyse the key stages in the social amplification of the physical and moral risks of media violen

This article analyses the interplay between politics and law in the recent attempts to strengthen the humanitarian commitment to saving lives in mare liberum. Despite a long-standing obligation to aid people in distress at sea, this so-called search and rescue regime has been marred by conflicts and political standoffs as states were faced with a growing number of capsising boat migrants potential

What does it mean to feel suspense? What kinds of situations give rise to the emotion? What is the connection between suspense and narrativity? And how is it that we can feel suspense upon repeat encounters with the same narrative? These questions are at the center of the first part of this study, where I develop and defend the ‘imminence theory of suspense’. Central to this theory is the claim th

Monte Carlo simulation is a useful technique to propagate uncertainty through a quantitative model, but that is all. When the quantitative modelling is used to support decision-making, a Monte Carlo simulation must be complemented by a conceptual framework that assigns a meaningful interpretation of uncertainty in output. Depending on how the assessor or decision maker choose to perceive risk, the

In this study the feasibility of applying proton-induced X-ray emission spectroscopy (PIXE) to the trace element analysis of human tooth enamel and dentine is investigated. Detection limits on the order of 1–10 ppm are obtained. Depth yields for different elements and proton energies are discussed. Enhancement calculations show that the effect for PIXE analysis is less important than for X-ray ind

Popular Abstract in Swedish Parkinsons sjukdom är en relativt vanlig kronisk neurologisk sjukdom som karaktäriseras av att nervceller i ett specifikt område djupt i hjärnan av okänd anledning successivt dör. Dessa celler producerar signalsubstansen dopamin, vilken bl a är nödvändig för normal rörelseförmåga. Motoriska symptom (skakningar, muskelstelhet, förlångsammade rörelser och balansstörningarThis explorative study aimed to apply, develop, and evaluate assessment methods at various levels in cell replacement therapy for Parkinson’s disease (PD). Observed motor effects in five grafted patients support that timed motor tasks and clinical ratings of parkinsonism are able to monitor motor function, but their psychometric properties need further attention. Using positron emission tomograp
