Northern hemisphere peatlands play an important role in the global carbon (C) cycle, accounting for about 30% of global soil C and similar to 10-25% of global natural methane (CH4) emissions. Satellite remote sensing has the potential for extracting continuous information related to C exchange rates at regional and global extents, yet, few studies have focused on peatlands. In this study we examin

Purpose: To presents results after 18 months of follow-up of a longitudinal study aiming at exploring the correlation between diabetic retinal vascular lesions and functional change. Methods: Patients were consecutively recruited from attendees to the screening program for diabetic retinopathy. Subjects are followed every sixth month for the first 3 years and thereafter annually up to 5 years. Pro

Survival after childhood cancer has improved substantially over recent decades. Although cancer in childhood is rare increasingly effective treatments have led to a growing number of long-term survivors. It is estimated that there are between 300,000 and 500,000 childhood cancer survivors in Europe. Such good survival prospects raise important questions relating to late effects of treatment for ca

There is a growing gap between tourism's rapidly growing greenhouse gas emissions and the sector's 'aspirational' emission reduction targets as well as the international policy consensus to reduce emissions from this and all other sectors of the economy. The transport component is the largest GHG contributor to the global tourism system. In the absence of supranational policy agreements to curb em

The "White and Green'' project completed under the EU SAVE Programme reviewed policies and measures to promote energy efficiency, which involved analysing the experience with instruments that are already implemented, and assessing innovative instruments that are proposed. In particular, the practicability of using ''White Certificates" energy efficiency) along the same lines as "Green Certificates

OBJECTIVE: To cross-validate, prospectively, the diagnostic performance of established ultrasound methods for discrimination of benign and malignant pelvic masses. METHODS: A total of 173 consecutive women with a pelvic mass judged clinically to be of adnexal origin underwent preoperative ultrasound examination including color and spectral Doppler techniques. A total of 149 tumors were benign, and

The post-failure convergence of the shortest path routing (SPR) protocols used in IP networks can be too slow to meet the restrictive requirements (i.e., maximum allowable delay, jitter, etc.) of the multimedia services and therefore new restoration mechanisms combined with IP routing are of interest. The paper addresses optimization of three potential rerouting mechanisms based on the IP fast rer

In the 1990s a contraction in state welfare in Sweden has been on its way and still seems to be so by joining forces. With focus on understanding the dynamics involved in the contractionprocess this paper aims to discuss the transition of welfare state commitment in Sweden. On the general level it should be seen as an attempt to adress the enigmatic and puzzeling questions of: How to explain chang

Background and aims: Caregivers of Parkinson's disease patients are vulnerable to detrimental factors related to caregiving because of the progressive course of the disease. Studies of care-givers of these patients are scarce. The aim of this study was to examine the caregiver burden in Parkinson's disease by analyzing caregiver and patient-related factors. Methods: Every 3(rd) patient with Parkin

BACKGROUND: Although death in old age is unavoidable, premature death-defined here as death before age 70 years-is not. To assess whether halving premature mortality by 2050 is feasible, we examined the large variation in premature death rates before age 70 years and trends over the past 50 years (1970-2019), covering ten world regions and the 30 most-populous nations. This analysis was undertaken

While many studies have examined carbon dynamics of boreal ecosystems following wildfire, research on forest-atmosphere carbon fluxes during widespread smoke events from adjacent active wildfires is limited. We examined eddy covariance carbon exchange adjacent to the May 2011 Utikuma Complex wildfire in central Alberta, Canada. Over a one-week period while the wildfire was burning <10 km from the

The impact of livestock grazing on soil organic carbon (SOC) stocks in the Sahel has been poorly documented due to a lack of data from different grazing intensities. This study evaluated SOC stocks under four grazing intensities within 0–30 cm soil depth in dry savanna ecosystems of Senegal. It also examined possible indirect relationships between grazing and SOC through herbaceous species diversi

This work has been done for Tetra Pak Distribution (TPD) at the Department of Engineering Logistic at the Lund Institute of Technology. My task was mainly to create a set of simulation models based on the Tetra Pak Distribution Lines. These models are going to be used by TPD to try to analyse the effect of the accumulation systems on the line efficiency. The inputs for the models are failure rate

According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billi

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

Mixed cropping systems can constitute important agroecological adaptation strategies for enhancing crop growth and productivity in view of climate change, while reducing the need for synthetic fertilizers and providing important ecosystem services. The aim of this study was to investigate growth, competitiveness, and productivity of two forage mixtures combining triticale (X triticosecale Wittmack

Deterioration of concrete structures is a worldwide problem. Environmental exposure is known to affect concrete strength in structures. While moisture affects rebound values by lowering them, carbonation does the opposite. The aim of the study was to determine the in-situ concrete strength of three bridge elements, namely, pier, abutment and deck and evaluate the environmental conditions such as m

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs.

Popular Abstract in Swedish Det norra barrskogsbältet, även kallat de boreala skogarna, sträcker sig runt hela norra halvklotet. Det utgör en tredjedel av den globala skogsytan, och innehåller hälften av den totala mängden kol finns lagrat i samtliga skogsekosystem. Trots de låga temperaturerna, den korta vegetationssäsongen och en liten mängd inkommande solenergi under året, är dessa ekosystem viIn boreal forests, the main factors limiting biomass production are the harsh climate, which combines a short growing season and low annual levels of incoming solar energy, and the limited availability of nitrogen. These limitations will be directly affected by climate change, and may in turn substantially affect the carbon budget of the boreal forests, the production of wood and biofuel, biodiver

OBJECTIVE: To obtain large scale and generalisable data on the long term predictive value of cytology and human papillomavirus (HPV) testing for development of cervical intraepithelial neoplasia grade 3 or cancer (CIN3+). DESIGN: Multinational cohort study with joint database analysis. SETTING: Seven primary HPV screening studies in six European countries. PARTICIPANTS: 24,295 women attending cerv
