Evidence of air pollution exposure, namely, ambient particulate matter (PM), during pregnancy and an increased risk of autism in children is growing; however, the unique PM sources that contribute to this association are currently unknown. The aim of the present study was to investigate local, source-specific ambient PM exposure during pregnancy and its associations with childhood autism, specific

Several authors have reported problems on service courses in basic probability and statistics: students may lack motivation, find the theory difficult or boring, others see no applications for the results. To remedy these problems we have developed a learning environment where two important components are applied problems and use of technology. However, the mere existence of applied problems and t

Different levels of user involvement in product design range from understanding user needs to co-designing with users. Previous research shows older patients face difficulties to handle the medication packaging. Yet the participation of older patients in pharmaceutical packaging design is underexplored. The purpose of this study is to explore the role of older patients in the design and developmen

Introduction and discussion of Stephen Wolfram's enormous book "A New Kind of Science" from 2002.

We provide an analysis of a randomly grown 2-d network which models the morphological growth of dendritic and axonal arbors. From the stochastic geometry of this model we derive a dynamic graph of potential synaptic connections. We estimate standard network parameters such as degree distribution, average shortest path length and clustering coefficient, considering all these parameters as functions

Background: Despite its well-established positive effects, exercise-based cardiac rehabilitation (exCR) is underused in patients following an acute myocardial infarction (AMI). The aim of the study was to identify factors associated with non-Attendance at exCR in patients post-AMI in a large Swedish cohort. Methods: A total of 31,297 patients who have suffered an AMI, mean age 62.4 ± 4 years, were

By counting the number of upcrossings of the mean level by a stationary Gaussian process one can estimate the mean frequency of the process. Here we present a frequency estimator based on the number of upcrossings of one unknown level hoped to be near the mean, and the percentage of the total observation time spent above the level. This is equivalent to observing upcrossings of a known level in a

The purpose of the article is to describe and compare the purchasing process for advanced versus basic logistics services. Further some specific observations are presented from the procurement of advanced third-party logistics services, with respect to service definitions, providers evaluations and contracts. The purchasing process of logistics services will in the future need to be more different

Abstract in UndeterminedA more or less continuous process of structural change, not least due to a globalizing economy, poses a number of challenges to regions and local communities. However, when firms or whole industries are phasing out, windows of opportunity open up. Empirical analyses of two recent plant closures in Skane point at the importance of retaining existing knowledge bases, and at t

This paper presents a survey where some quality requirements that commonly affect software architecture have been prioritized with respect to cost and lead-time impact when developing software platforms and when using them. Software platforms are the basis for a product-line, i.e. a collection of functionality that a number of products are based on. The survey has been carried out in two large sof
