De protestantiska kyrkorna liksom kyrkorna i Östeuropa uppmuntrar präster att ingå äktenskap. Att den katolska kyrkan håller fast vid celibatet har en disciplinär funktion. I artikeln ges historiska perspektiv på prästcelibatet, kritiken mot detta och motiven för dess bibehållande.

Det arkeologiska perspektivets tidsdjup ger kunskap om förändringar av människans livsval. De arkeologiska föremålen betraktas som ett slags tidsmarkörer som materialiserar en tids idéer om formgivning, tillverkning och konsumtion av produkter och hur dessa kan ingå i en föreställningsvärld om tid. Vår egen tids föreställning om tid påverkar ytligt tolkningen av forntida material.

Routine endomyocardial biopsy (EMB) to detect acute cellular rejection (ACR) late (>1 year) after heart transplantation (HT) remains debated. To gain knowledge on late ACR and thereby approach this issue, we studied the incidence, predictors, and outcome of late ACR. 815 late EMBs from 183 patients transplanted 1988-2010 were retrospectively reviewed until June 30, 2012. Only 4.4% of the routine a

Background: There is a need for increased understanding of the pre-diabetic period in individuals with high risk of type 1 diabetes from the general population. Methods: High-risk children (n = 21) positive for multiple islet autoantibodies were identified by autoantibody screening within the All Babies in Southeast Sweden study. The children and their parents were enrolled in a 2-year prospective

A survey of four co-design tools for joint analysis, simulation, and design of computer-based control systems developed within the Swedish ARTES programme is presented. The tools allow simultaneous treatment of the control aspects and the computing and communication aspects of the control problems. The tools are Jitterbug and TrueTime developed at the Department of Automatic Control LTH, Lund Univ

The paper presents the control server, a real-time scheduling mechanism tailored to control and signal processing applications. A control server creates the abstraction of a control task with a specified period and a fixed input-output latency shorter than the period. Individual tasks can be combined into more complex components without loss of their individual guaranteed fixed-latency properties.

Background and aims: Pharmacotherapy can be an important part of the continuum of care for alcohol use disorder (AUD). The Swedish universal health-care system emphasizes provision of care to marginalized groups. The primary aim was to test associations of neighborhood deprivation and disadvantaged social status with receipt of AUD pharmacotherapy in this context. Design: Data from linked populati

The demand for developing creativity among doctoral students is found in a number of educational policies all over the world. Yet, earlier studies on Swedish doctoral education suggest that doctoral students’ creativity is not always encouraged. Based on a critical hermeneutic approach and cases in four different disciplines, the aim of this study was therefore (1) to explore different shapes of d

One of the key-principles of the iron-sulphur world theory is to bring organic molecules close enough to interact with each other, using the surface of pyrite as a substrate in a hydrothermal setting. The present paper explores the relationship of pyrite and organic matter in a hydrothermal setting from the geological record; in hydrothermal calcite veins from Carboniferous limestones in central I

In the 23-km-diameter Haughton impact structure, Canadian High Arctic, in sulfate-rich bedrock, widespread hydrothermal sulfide mineralization occurred in breccias formed during the impact. The sulfides exhibit extreme sulfur isotopic fractionation relative to the original sulfate, requiring microbial sulfate reduction by thermophiles throughout the crater. This evidence of widespread microbial ac

Limestone samples from the Cambro-Ordovician Durness Group were crushed, aciddigested and searched for evidence of micrometeorites. Eleven melted micrometeorites were extracted from the magnetic fraction of samples from the Balnakeil and Croisaphuill formations near the top of the group. Other formations in the Durness Group did not yield micrometeorites. Only melted spherules with a distinctive d

Impact-generated hydrothermal systems are commonly proposed as good candidates for hosting primitive life on early Earth and Mars. However, evidence of fossil microbial colonization in impact-generated hydrothermal systems is rarely reported in the literature. Here we present the occurrence of putative fossil microorganisms in a hydrothermal system of the 89 Ma Dellen impact structure, Sweden. We

On Earth, the deep subsurface biosphere of both the oceanic and the continental crust is well known for surviving harsh conditions and environments characterized by high temperatures, high pressures, extreme pHs, and the absence of sunlight. The microorganisms of the terrestrial deep biosphere have an excellent capacity for adapting to changing geochemistry, as the alteration of the crust proceeds
