Puerpural fever still exist. A rare condition that must be kept in mind All 33 claims to the Swedish National Patient Insurance (LÖF) in 2010-2014 related to obstetric infections, of which 14 were due to endometritis, were examined. Nine women suffered from fulminant infections consistent with classical puerperal fever (childbed fever), 2 of which were life-threatening. They occurred unexpectedly,
Context. V2492 Cyg is a young pre-main sequence star presenting repetitive brightness variations of significant amplitude (R - 5 mag) whose physical origin has been ascribed to both extinction (UXor-type) and accretion (EXor-type) variability, although their mutual proportion has not been clarified yet. Recently, V2492 Cyg has reached a level of brightness ever registered in the period of its docu
This study examines the interdependence between research and development (R&D) resources, coopetitive performance, and extent of cooperation in development-related standardization settings that involve network effects. Coopetitive performance is measured as the firm’s influence on the change process of standards. Cooperation is measured as the number of firm technology partners in influencing
Migration distance and seasonal redistribution patterns may vary between and within bird populations. A common pattern is leap-frog migration, in which northerly breeding populations migrate farther and winter south of more southerly breeding populations. Another common pattern is difference in migration distances between males and females within the same population. Evidently different population
This study examines the interdependence between R&D resources, coopetitive performance and extent of cooperation in development-related standardization settings that involve network effects. Coopetitive performance is measured as the firm’s influence on the change process of standards.

Acid mine drainage (AMD) is one of the most serious environmental problems in mining worldwide. One of the largest unexploited coal basins in the world is located in Moatize. It contains about 23 billion metric tonnes of coal. The coal mining there is done in riparian sections of the Zambezi River basin, making it particularly vulnerable to pollution. Much of the coal waste is produced by a number
At the same time as our dependence on IT systems increases, the number of reports of problems caused by failures of critical IT systems has also increased. Today almost every system or service, e.g., water, power supply, transportation, is dependent on IT systems, and failure of these systems has serious and negative effects on society. In general, governmental organizations are responsible for de
Communication in industrial environments is an important scenario for ultra wideband (UWB) systems. The characteristics of this environment differ considerably from office environments, where most of the channel measurements reported in the literature are performed. In this paper, we present the results and analysis of UWB channel measurements in an industrial environment. We investigate both peer
This paper discusses the underlying causes behind the masculinization of poverty during the period of 1957–1981 in Sweden. Testable hypotheses are derived from a theoretical framework. The findings suggest that the male role as breadwinner disappeared during the analysed period. Lowly educated men and especially male immigrant labour lost their labour market position when industrial society gave w
This abstract is based on a pilot study from an ongoing project focusing the implementation of a digital platform offering support for both the patient- and workflow at a primary healthcare center in Western Sweden. The overarching aim of the project is to follow the introduction and adaptation (normalization) of the platform in primary healthcare centers to study how digital support of the patien
Hotspot tracks (quasilinear chains of seamounts, ridges, and other volcanic structures) provide important records of plate motions, as well as mantle geodynamics, magma flux, and mantle source compositions. The Tristan-Gough-Walvis Ridge (TGW) hotspot track, extending from the active volcanic islands of Tristan da Cunha and Gough through a province of guyots and then along Walvis Ridge to the Eten
Background and ObjectivesSurvival estimates for individuals with Alzheimer disease (AD) are informative to understand the disease trajectory, but precise estimates for atypical AD variants are scarce. Atypical AD variants are characterized by nonamnestic phenotypes, an early onset, and lower prevalence of APOEϵ4 carriership, which affect the AD trajectory. We aimed to provide survival estimates fo
Evaluation of IT investments is a difficult and complicated issue. This chapter presents a framework for control of IT investments with the aim of providing decision-makers with a clear picture of individual IT investments as well as an aggregated level where all IT investments are combined into a total picture. The framework has been developed using an action–research approach.In a number of work
Students at higher technical educations e.g., bachelors and masters, are traditionally taught in software programming and factory automation. Students at higher economical and management schools are exposed to different strategies and their economical impacts. However, in many education programs, the larger perspective, of how to combine the technical and the economical aspects is not highlighted.
In the automotive industry, the piezo-based in-cylinder pressure sensor is getting commercialized and used in production vehicles. For example, the pressure sensor offers the opportunity to design algorithms for estimation of engine emissions, such as soot and NO, during a combustion cycle. In this paper a zero-dimensional NO model for a diesel engine is implemented that will be used in real time.
Multipath fading is one of the main challenges in transmission over wireless broadband relay channels due to frequency selectivity, which may deteriorate the received signal. Exploiting the extra source of multipath diversity, aside from cooperative (user) diversity, is important when coping with these wireless channel limitations. In this correspondence, we propose a new distributed space-frequen
