In order to fulfil the requirements of available energy resources, there is a great need to obtain a sustainable and environmentally friendly energy utilization using combustion processes. In order to do this, it is of utmost importance to utilize non-intrusive diagnostic techniques with high spatial and temporal resolution which can characterize the combustion process and also validate combustion

The objective of this review is to examine how drug spending in different age groups changed during the 1990s. Time series analysis of registered data on prescription drug spending were performed, along with two decompositions, one of which was spending in three components: price, quantity (defined daily dose) and residual. The size of the residual is a measure of the impact of changes in drug tre

The aim is to investigate the effect of availability and level of detail of data on cost estimates of alcohol consumption. Using the recent Swedish cost of alcohol study as baseline, limitations on data are applied, forming two models. The costs of alcohol in Sweden are re-estimated in the two models and compared to the baseline, to establish the magnitude and direction of the bias resulting from

Background: Studies have found a positive effect of low/moderate alcohol consumption on wages. This has often been explained by referring to epidemiological research showing that alcohol has protective effects on certain diseases, i.e., the health link is normally justified using selected epidemiological information. Few papers have tested this link between alcohol and health explicitly, including

To test potential bilateral causalities relation between HIV-AIDS mortality and GDP, we propose a simple Granger noncausality test for heterogeneous panel data models. 44 African countries are selected for annual pooled data from 1990 to 2009. Results are presented for the heterogeneous noncausality hypothesis (HENC), which tests, for each cross-section unit, the nullity of all the coefficients of

PurposeTo estimate Swedish experience-based value sets for EQ-5D health states using general population health survey data.MethodsApproximately 45,000 individuals valued their current health status by means of time trade off (TTO) and visual analogue scale (VAS) methods and answered the EQ-5D questionnaire, making it possible to model the association between the experience-based TTO and VAS values

This paper provides a descriptive analysis of the level of and change in cigarette smoking, excessive alcohol consumption and body weight in Nordic countries and compares them with non-Nordic OECD countries. Our results show that the average prevalence of daily smokers is significantly lower for Nordic countries compared to non-Nordic countries. Four out of five Nordic countries are below the non-

There is an increasing body of evidence that the intensity in which alcohol is drunk is of greater concern than the frequency or overall quantity consumed. This paper provides an extensive analysis of the demand for alcohol as measured by total quantity, frequency, and intensity. A unique large sample of cross-sectional data from Sweden 2004–2011 allows reduced-form alcohol demand equations to be

Background: The health care costs of kidney transplantation and dialysis are generally unknown. This study estimates the Swedish health care costs of kidney transplantation and dialysis over 10 years from a health care perspective.Method: A before–after design was used, in which the patients served as their own controls. Health care costs the year before transplantation were assumed to continue in

This paper concerns the VSC-HVDC application to improve the long-term voltage stability. For this purpose the NORDIC32 test system is considered. All necessary dynamics to study the long-term voltage stability are included in the test system. An appropriate control strategy for VSC-HVDC is proposed in the paper. The goal is to reach the best condition from long-term voltage stability perspective w

The mechanisms leading to blowoff were investigated numerically by analyzing bluff body stabilized flame at two conditions: a condition far from blowoff to a condition just prior to blowoff. Large eddy simulations have been used to capture the time dependent, three-dimensional evolution of the field. The results were first validated to available experimental data, showing very good agreement for t

Refugee rights are reserved for the few lucky enough to evade the sophisticated deterrence regime, while the vast majority of the world’s refugees are referred to a life in semi-permanent limbo.

BackgroundFatty acids from vegetable oils are useful building blocks for industrial materials. The purpose of this work was to prepare erucic acid with high purity from a vegetable oil. High purity erucic acid is used for the production of erucamide with applications in plastics manufacturing. A newly developed transgenic Crambe line produces seed oil with 68 % erucic acid compared to 53 % in the

This volume constitutes the first anthology of texts in cognitive semiotics - the new transdisciplinary study of meaning, mind and communication that combines concepts and methods from semiotics, cognitive science and linguistics - from a multitude of established and younger scholars. The chapters deal with the interaction between language and other semiotic resources, the role of consciousness an

The causes and extent of regional inequality in the process of economic growth are at the core of historical economic research. So far, much attention has been devoted to studying the role of industrialization in driving regional divergence. But empirical studies on relatively unequal countries such as Italy or Spain show that inequality was already high when their modern industrialization began (

Today there is a need for energy-efficiency measures in historic buildings. Clarifying both opportunities and risks for energy-efficiency measures in historic buildings is a challenging task. To ensure that such measures will provide the planned result without damage to the building or poor indoor climate, a skilled holistic approach is required. To be able to propose accurate measures requires a
