Congestion charging was - as a trial - introduced in Stockholm from January 3rd to July 31st 2006. After the referendum in September 2006, the charging system was finally introduced as permanent from August 2007 with some adjustments to the Trial design. The idea of congestion charging is unique in a Swedish context. and the introduction of the Stockholm system has been highly controversial. Consi
1 Two new concepts describing the origin of insects caught ill an attractive trap are presented. 2 Male European pine sawflies Neodiprion sertifer Geoffroy (Hymenoptera: Diprionidae) were marked and released from 50, 100, 200, 400 and 800 m in the four cardinal directions around a centrally placed pheromone trap. 3 Based on linear regression of transformed data, we calculated the seasonal sampling
Climate and Trade Policies in a Post-2012 World is a collection of short forward-thinking articles by leading experts on the relationship between trade and climate change policies. The idea for developing this publication was conceived at the “International Workshop on Post-2012 Climate and Trade Policies”, jointly organized in September 2008 by the United Nations Environment Programme (UNEP) and
The aim of this thesis, The Historical Novel and Historical Consciousness in ten- to twelve-year-olds - Maj Bylocks Drakskeppstrilogi in Theory and Practice, is to illustrate the possibilities for pupils of the ages between ten to twelve to develop their historical consciousness by participating in classroom work making use of fiction as a central source of knowledge.

While many laboratory studies have focused on the short term effects of biochar addition to soil), there have been comparatively few tracing its longer term effects in the field. This study investigated the multiyear impact of biochar on crop performance and soil quality with specific emphasis on carbon (C) and nitrogen (N) cycling over a 3 y period. Biochar was added to an agricultural field at 0
Thyroid cancer has peak incidence among women of reproductive age, and growth factors, which have procarcinogenic properties, may play an important etiologic role. However, the association between fetal growth rate during a woman's pregnancy and her subsequent risk of thyroid cancer has not been previously examined. We conducted a national cohort study of 1,837,634 mothers who had a total of 3,588
Popular Abstract in Swedish Döva barns begreppsbildning i matematik Denna studie tar utgångspunkt i frågan varför många döva barn har svårt att lära sig matematik. Studiens syfte är att belysa döva barns begreppsbildning i ämnet matematik genom att beskriva hur några döva barn uttrycker sig och agerar på väg mot förståelse av två centrala matematiska begrepp, nämligen multiplikation med heltal ochThe question why deaf children have difficulties in learning mathematics is the basis of this study. The aim of the study is to illuminate deaf children’s concept formation in mathematics by describing how some deaf children express themselves and act on their way towards understanding two basic concepts, the concept of multiplication with whole numbers and the concept of length. Theories develope
Philosophers of science have often favoured reductive approaches to how-possibly explanation. This article identifies three varieties of how-possibly explanation and, in so doing, helps to show that this form of explanation is a rich and interesting phenomenon in its own right. The first variety approaches “How is it possible that X?” by showing that, despite appearances, X is not ruled out by wha
Background: In the COMET study, carvedilol improved survival compared to metoprolol tartrate in 3029 patients with NYHA II-IV heart failure and EF <35%, followed for an average of 58 months. Aims: To evaluate whether the effect on overall mortality was specific for a particular mode of death. This may help to identify the mechanism of the observed difference. Methods: Of the 1112 total deaths, 972
Aim: To quantify avian distribution shifts and the extent of niche tracking in response to changing temperature and precipitation patterns. Location: Sweden. Methods: We used abundance monitoring data to quantify changes in bird species distributions between two time periods, 2000-02 and 2010-12. First we examined shifts at the level of whole distributions using population centroids in temperature
Importance: Accurate blood-based biomarkers for Alzheimer disease (AD) might improve the diagnostic accuracy in primary care, referrals to memory clinics, and screenings for AD trials. Objective: To examine the accuracy of plasma β-amyloid (Aβ) and tau measured using fully automated assays together with other blood-based biomarkers to detect cerebral Aβ. Design, Setting, and Participants: Two pros
In the Nordic countries, as in other contemporary societies across the world, increased migration following from conflicts, persecution and natural disasters has led to the arrival of and ensuing responsibility for cohorts of refugees and asylum seekers, many of which are underage children. With small chances of a safe return to their homelands for years to come, these children rely on the policie
1. In rat isolated hepatic arteries contracted with phenylephrine, acetylcholine and the calcium ionophore A23187 each elicit endothelium-dependent relaxations, which involve both nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF). However, the contribution of prostanoids to these responses, and the potential interaction between EDHF and other endothelium-derived relaxing fact
Background: The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new
BackgroundRotator cuff tears pose a huge socioeconomic burden. Our study uses Fourier transform infrared spectroscopy (FTIR) as it is a quick, non-manipulative and non-destructive test, which can identify a wide range of chemical targets from small intraoperatively obtained specimens. The aim of this study was (i) to characterise the chemical and structural composition of rotator cuff tendons and
BACKGROUND: Type 2 diabetes is one of the leading causes of chronic kidney failure, which increases globally and represents a significant threat to public health. People from the Middle East represent one of the largest immigrant groups in Europe today. Despite poor glucose regulation and high risk for early-onset insulin-deficient type 2 diabetes, they have better kidney function and lower rates
Det finns runt 100 000 blinda och kraftigt synnedsatta individer (BKSI:er) i Sverige. Sådan synnedsättning leder till en kraftigt minskad förmåga för självständig förflyttning och lägre livskvalité, med ökad risk för arbetslöshet, trafikolyckor, en stillasittande livsstil och depression. Hälften av alla käpp- och hundanvändare är med om en huvudkollision årligen, och drygt var tredje för en fallolReduced independent mobility of blind and low-vision individuals (BLVIs) cause considerable societal cost, burden on relatives, and reduced quality of life for the individuals, including increased anxiety, depression symptoms, need of assistance, risk of falls, and mortality. Despite the numerous electronic travel aids proposed since at least the 1940’s, along with ever-advancing technology, the m
Atmospheric inversion approaches are expected to play a critical role in future observation-based monitoring systems for surface fluxes of greenhouse gases (GHGs), pollutants and other trace gases. In the past decade, the research community has developed various inversion software, mainly using variational or ensemble Bayesian optimization methods, with various assumptions on uncertainty structure
In this paper we conduct a multi-criteria analysis (MCA) from a multiple stakeholder point of view for the design of access and benefit sharing (ABS) agreements concerning genetic resources, in particular regarding the access component of such agreements. We start by analyzing the objectives defined by international law (viz. the Convention on Biodiversity and the Nagoya Protocol) that every party
