Human influences on evolution, and the ecological and societal consequences

Humans have dramatic, diverse and far-reaching influences on the evolution of other organisms. Numerous examples of this human-induced contemporary evolution have been reported in a number of ‘contexts’, including hunting, harvesting, fishing, agriculture, medicine, climate change, pollution, eutrophication, urbanization, habitat fragmentation, biological invasions and emerging/disappearing diseas

The fate of fixed nitrogen in marine sediments with low organic loading : An in situ study

Over the last decades, the impact of human activities on the global nitrogen (N) cycle has drastically increased. Consequently, benthic N cycling has mainly been studied in anthropogenically impacted estuaries and coasts, while in oligotrophic systems its understanding is still scarce. Here we report on benthic solute fluxes and on rates of denitrification, anammox, and dissimilatory nitrate reduc

Mapping the Ca2 + induced structural change in calreticulin

Calreticulin is a highly conserved multifunctional protein implicated in many different biological systems and has therefore been the subject of intensive research. It is primarily present in the endoplasmatic reticulum where its main functions are to regulate Ca2 + homeostasis, act as a chaperone and stabilize the MHC class I peptide-loading complex. Although several high-resolution structures of

Sex-specific outcomes with addition of defibrillation to resynchronisation therapy in patients with heart failure

Objective Among primary prevention patients with heart failure receiving cardiac resynchronisation therapy (CRT), the impact of additional implantable cardioverter defibrillator (ICD) treatment on outcomes and its interaction with sex remains uncertain. We aim to assess whether the addition of the ICD functionality to CRT devices offers a more pronounced survival benefit in men compared with women

Lieb–Thirring Inequalities for Finite and Infinite Gap Jacobi Matrices

We establish Lieb–Thirring power bounds on discrete eigenvalues of Jacobi operators for Schatten class perturbations under very general assumptions. Our results apply, in particular, to perturbations of reflectionless Jacobi operators with finite gap and Cantor-type essential spectrum.

In recent years, Scandinavian scholars have shown an increasing interest in German research on confessionalisation in early modern Europe. In this article, I set out the research topic for a Scandinavian audience and suggest how best to use the concept of confessionalisation when working with Scandinavian sources. The concept of confessionalisation focuses on the creation of the three main confess

Time-Continuous Quasi-Monte Carlo Ray Tracing

Domain-continuous visibility determination algorithms have proved to be very efficient at reducing noise otherwise prevalent in stochastic sampling. Even though they come with an increased overhead in terms of geometrical tests and visibility information management, their analytical nature provides such a rich integral that the pay-off is often worth it. This paper presents a time-continuous, prim

Den franske kammartjänarens resa : minnen från länderna i norr på 1660-talet

Detta är en monografi skriven i samarbete med litteraturvetaren Ingemar Oscarsson. Boken bygger på ett opublicerat franskt 1600-tals manuskript, ms. 1143, som bär titeln Mémoires d’un voyage fait dans les pays septentrionaux en l’an M.D.C.LXIII. Originalmaterialet är ett inbundet dokument i kvartoformat på 280 handskrivna sidor.

Berättelsen om spegelbilden : det höviska och det narrativa begäret

Detta är en monografi som förenar den filologiska disciplinens traditionella infallsvinklar (textedition, översättning, litterära och lingvistiska analyser) med modern litteraturteori. Boken ingår i Ellerströms akademiska serie Eureka och innehåller en kritisk textedition av den fornfranska berättelsen Li Lais de l’ombre av Jean Renart (962 verser). Texten är etablerad med utgångspunkt i ett av de

Tribology of flexible and sliding spinal implants: development of experimental and numerical models

New fusionless devices are being developed to get over the limits of actual spinal surgical treatment, based on arthrodesis. However, due to their recentness, no standards exist to test and validate those devices, especially concerning the wear. A new tribological first approach to the definition of an in vitro wear protocol to study wear of flexible and sliding spinal devices is presented in this

Detta är en ny textkritisk utgåva av en unik version av hjältedikten Théséus de Cologne som ingår som en del av en krönika om hertigarna från Savojen. Det ingår också en tolkning av verkets tillblivelse och betydelse i den historiska och intertextuella kontext som författaren befann sig i under skrivandet.

Pedicle Screw Fixation Study in Immature Porcine Spines to Improve Pullout Resistance during Animal Testing

The porcine model is frequently used during development and validation of new spinal devices, because of its likeness to the human spine. These spinal devices are frequently composed of pedicle screws with a reputation for stable fixation but which can suffer pullouts during preclinical implantation on young animals, leading to high morbidity. With a view to identifying the best choices to optimiz

Does surface roughness influence the primary stability of acetabular cups? A numerical and experimental biomechanical evaluation.

Most acetabular cups implanted today are press-fit impacted cementless. Anchorage begins with the primary stability given by insertion of a slightly oversized cup. This primary stability is key to obtaining bone ingrowth and secondary stability. We tested the hypothesis that primary stability of the cup is related to surface roughness of the implant, using both an experimental and a numerical mode

Pullout strength of all suture anchors in the repair of rotator cuff tears: a biomechanical study.

PURPOSE: We evaluated the biomechanical strength of two all suture anchors (ASA) of reduced diameter (1.4 mm) and compared them with the standard screw anchor (SA) with larger diameter (5.5 mm) used in rotator cuff tears. METHODS: We conducted 30 uniaxial vertical pullout tests using Material Testing System Instron 5566A until failure of the anchorage defined as rupture of the threads or anchor or

High-throughput analysis of the structural evolution of the monoolein cubic phase in situ under crystallogenesis conditions

We have tracked the structural evolution of the monoolein bicontinuous cubic phase under in meso crystallogenesis conditions. Significantly, all measurements have been carried out in situ within a crystallisation plate reproducing the exact conditions during a crystallisation trial. The structure of the MO cubic phase, doped with a small concentration of amyloid-beta peptide, was measured 1 day, 5

Self-efficacy in the context of heart transplantation - a new perspective

AIMS AND OBJECTIVES: An in-depth exploration of self-efficacy among heart transplant recipients by means of Bandura's self-efficacy theory.BACKGROUND: An essential component of chronic illness management is self-management, which refers to activities carried out by people to create order, structure and control in their lives. Self-efficacy is an important aspect of self-management, which seems to
