Costs related to pollen competition have rarely been considered, but are expected in the case of sexual conflict where male and female sexual functions have opposing evolutionary interests. In Collinsia heterophylla, delayed stigma receptivity is beneficial as it enhances pollen competition. A sexual conflict over timing of stigma receptivity has been proposed in this species as early pollination,
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed using the Large Hadron Collider proton-proton collision data sample at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector that correspo
Background and purposeHYPO-RT-PC was the first phase 3 trial showing the long-term efficacy and safety of extremely hypofractionated radiotherapy schedules (ultra-hypofractionation or stereotactic body radiotherapy) compared with standard radiotherapy in localised prostate cancer. We aimed to verify their safety in the context of a clinical trial, by comparing events of potentially radiotherapy-re
Hepatitis A virus (HAV) remains a preventable cause of acute viral hepatitis, with an estimated 159 million new infections and 39 000 deaths in 2019. Although improved care and hygiene reduced deaths, global incidence rose by approximately 4%, driven by increased symptomatic cases and population growth. The availability of safe and highly immunogenic vaccines and the absence of chronic carriage ma
OBJECTIVE: To study the possibility of improving blood lipids, glucose tolerance and insulin sensitivity in women with impaired glucose tolerance and a history of gestational diabetes by merely changing the glycaemic index (GI) and dietary fibre (DF) content of their bread. DESIGN: Randomized crossover study where test subjects were given either low GI/high DF or high GI/low DF bread products duri
We present a new algorithm to calculate the near-field distribution of scattered light of multiple nanospheres based on recursive order-of-scattering (OS) and the matrix inversion approaches, which avoids the divergent problem encountered in origin OS method at the resonance condition. Using this method, we investigate the light-transport properties of linear chains of Ag nanospheres. We found a m
Head-and-neck tumors are often situated at an air-tissue interface what may result in an underdosage of part of the tumor in radiotherapy treatments using megavoltage photons. especially for small fields. In addition to effects of transient electronic disequilibrium, for these small fields, an increased lateral electron range in air will result in an important extra reduction of the central axis (
Abstract - Vol. I In this Volume of the thesis, which consists of two volumes, a risk analysis framework for application in the maritime transport system of packaged dangerous goods (PDG) is presented. In many countries, dangerous goods risks have been ranked high among public concerns. Such concerns are mainly due to the increasing volume of dangerous goods, human safety and health and environme
Popular Abstract in Swedish Populærvidenskablig sammenfatning på dansk Både løbebiller og springhaler er nyttedyr i det danske landbrugsland. Løbebiller er oftest betragtet som rovdyr, der spiser skadelige insekter i marken og er derved medvirkende i skadedyrsbekæmpelsen. Springhaler er minder insekter, som oftest lever i de øverste jordlag og som hovedsagelig spiser svampehyfer. Svampene nedbrydTo optimise fitness is a continuous process which assists species survival in changing environments. Choosing an optimal diet is an essential part of the optimisation process and a key element of optimal foraging theory. The relationship between food choice and fitness optimisation has been tested on three ground beetles and several collembolan species by using food items naturally occurring in th
Popular Abstract in Swedish Elektrostatiske vekselvirkninger mellem biomolekyler er vigtige, ikke bare i biologiske systemer, men også i flere tekniske sammenhænge. I denne afhandling studereres en række forskellige egenskaber, relevant for særligt proteiner. Således har vi ved hjælp af molekylær simulering undersøgt hvorledes proteiner vekselvirker med protoner, salte, andre peptider og proteinerElectrostatic interactions in bio-molecular systems are important not only in the living cell but also in more technical applications. Using molecular simulation as well as approximate theories the properties of a number of aqueous protein solutions have been studied. This includes interactions with other proteins, protons, charged membranes as well as flexible polyelectrolytes. The focus is on el
The formation name Almelund Shale is proposed for a lithostratigraphically defined unit to replace the outdated chronostratigraphical designations Upper Didymograptus Shale and Dicellograptus Shale in the Middle and lowermost Upper Ordovician succession in Scania. The Almelund Shale is a lithologically uniform unit of dark-grey to black shales with rare carbonate interbeds between the Komstad Lime
BACKGROUND: The role of sleeping problems in the causal pathway between job strain and musculoskeletal pain is not clear. Purpose: To investigate the impact of sleeping problems and job strain on the one-year risk for neck, shoulder, and lumbar pain. METHOD: A prospective study, using self-administered questionnaires, of a healthy cohort of 4,140 vocationally active persons ages 45-64, residing in
Tapasin is a subunit of the transporter associated with antigen processing (TAP). It associates with the major histocompatibility complex (MHC) class I. We show that tapasin interacts with beta- and gamma-subunits of COPI coatomer. COPI retrieves membrane proteins from the Golgi network back to the endoplasmic reticulum (ER). The COPI subunit-associated tapasin also interacts with MHC class I mole
Background Long-term outcome after hematopoietic stem cell transplantation including late transplant-related events is of increasing interest. The aim of this study was to evaluate the incidence of cardiovascular events after allogeneic HSCT and to search for their risk factors. Design and Methods This is a retrospective mutlicenter European Group of Blood and Marrow Transplantation (EBMT) analysi
A search for pair production of vector-like quarks, both up-type (T) and down-type (B), as well as for four-top-quark production, is presented. The search is based on pp collisions at TeV recorded in 2012 with the ATLAS detector at the CERN Large Hadron Collider and corresponding to an integrated luminosity of 20.3 fb(-1). Data are analysed in the lepton-plus-jets final state, characterised by an
The results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported. The analysis is performed with proton-proton collision data at root s = 8 TeV collected with the ATLAS detector at the LHC in 2012 corresponding to an integrated luminosity of 20 fb(-1). The lightest supersymmetric particle (LSP) is taken to be
This thesis explores the effects of institutional arrangements for innovation in clusters. Clusters have become one of the most popular concepts in innovation policy studies in recent years. They have been ascribed as places with structures that reduce transaction costs, and enable innovation processes due to the prevalence of different types of externalities. The focus of this dissertation is on
