It is expected that fuel cells will play a significant role in a future sustainable energy system. They are energy efficient, fuel can be produced nearly locally and, when a renewable fuel such as ethanol, methanol and biogas is used, there are no net emissions of greenhouse gases. Fuel cells have during recent years various progresses, but the technology is still in the early phases of developmen
Popular Abstract in Swedish "Män födda 1914" är en studie som påbörjades 1982 för att studera hjärt- och kärlsjukdomar. Studien bedrivs vid Institutionen för samhällsmedicin vid Universitetssjukhuset MAS. Alla män, födda jämn månad 1914 och bosatta i Malmö, inbjöds att deltaga. Totalt inbjöds 621 män, då 68 år gamla, och av dessa deltog 500. Då man jämförde deltagare med icke-deltagare kunde man k"Men born in 1914" is a prospective cohort study on the epidemiology of cardiovascular disease. The study is run by the Department of Community Medicine, Lund University, Malmö. Five hundred men participated in the study when it started with a baseline examination in 1982/83. The men were then 68 years old. The psychological part of the study included tests of cognitive function and the serial Col

A discussion of external and internal causes of change in the Nordic countries c. 1000-2010.
The spectral representation of a moving average process obtained as a convolution of a kernel with a general noise measure is studied. A proof of the spectral theorem that yields explicit expression for the spectral measure in terms of the noise measure is presented. The main interest is in noise measures generated by second order Lévy motions. For practical considerations, such measures are easil
Alluvial channel sands in active ephemeral streams are potentially highly productive aquifers that are normally fully recharged annually. The groundwater resource is constrained by the limited three-dimensional extent of these aquifers. Concepts are developed that propose an increase in alluvial aquifer dimensions at geological boundaries. Multi-electrode resistivity and ground penetrating radar a
Reprint of chapter in C. Shore and D. Haller, 'Understanding Corruption: Anthropological Perspectives' from 2005. Discusses doing good and corruption fighting as a new wave, with a focus on the international NGO Transparency International.
When the ethnographer Wilson Wallis did his first fieldwork among the Canadian Mi’kmaq Indians 1911, one recurrent character in their oral tradition was the traditional culture hero Kluskap. When Wallis returned to Nova Scotia in 1953 he found that not many Mi’kmaq in the thirties had heard about Kluskap, and if they had, it was through books or the television series “The Adventures of Glooscap”.

Numerical analysis, such as the finite element method is the most used computational procedure for nonlinear deformation and strength analysis of structures. In order to obtain meaningful results the material behaviour must be described and simulated accurately. Another important element in order to perform the simulation is a robust and accurate numerical integration algorithm. The present paper
