We performed a large nested case-control study within the Finnish and Icelandic maternity cohorts to verify/falsify the association of maternal EBV infection with an increased risk of acute lymphoblastic leukemia (ALL) in the offspring found in previous studies. All hematologic malignancies diagnosed among children born during 1983 to 2006 in Finland and 1997 to 2005 in Iceland were identified thr

This article presents results from measurements of hydroxide ion transport between a concrete and a floor screed of a lower alkalinity than the concrete. As many floor coverings and floor adhesives are sensitive to high alkaline conditions it is important to know how hydroxide ions are transported to be able to evaluate the long-term function of floor constructions. It was found that only minor tr

In Sweden, 13 % of all transport is related to business travelling, resulting in significant emissions of not only CO2, but also of NOx, VOC, CO and particle matter. The implication for business will not only come in the form of ecological impacts affecting the natural resource base; as people around the world wake up to the fact that issues, like climate change, are a real threat to their welfare

It is speculated that virtual environments (VE) might be used as a training tool in brain injury rehabilitation. The rehabilitation process often involves practicing so-called instrumental activities of daily living (IADL), such as shopping, cooking, and using a telephone. If a brain injury patient is to practice such activities in a VE, the patient must be able to navigate the viewpoint and inter

Potentially large storage requirements and long initial decoding delays are two practical issues related to the decoding of low-density parity-check (LDPC) convolutional codes using a continuous pipeline decoder architecture. In this paper, we propose several reduced complexity decoding strategies to lessen the storage requirements and the initial decoding delay without significant loss in perform

Two methods (including randomization) are studied for increasing the uncertainty concerning n ³ 1 transmitted messages and an applied key. Furthermore, it is shown that encryptions which perform equally well for n = 1 may perform differently when n > 1.

Many cluster studies have focused on growth regions and industries covering only the early phases of cluster development. Little attention, however, has been paid to the renewal of clusters in old industrial regions. The aim of the paper is to address the question of how clusters renew themselves in such regions and how they adjust to changes in their environment. After identifying relevant factor
