The reduction of greenhouse gas emission and the effort of carbon neutrality require the improvement of spark-ignition (SI) engines in terms of efficiency and capability to operate on renewable fuels. The electrode wear of spark plugs, used for ignition of novel fuels and lean mixtures, emerges as a significant challenge in this transition. Understanding the physical mechanism and influence from s
Fludarabine, cyclophosphamide and rituximab (FCR) is first-line treatment for medically fit chronic lymphocytic leukemia (CLL) patients, however despite good response rates many patients eventually relapse. Whilst recent high-throughput studies have identified novel recurrent genetic lesions in adverse-prognostic CLL, the mechanisms leading to relapse after FCR therapy are not completely understoo
Avian time-activity budgets are known to be affected by many environmental factors. The aim of this study was to examine whether roosting times of common ravens Corvus corax are affected by inclement weather conditions in response to increased energy demands. The study was conducted at a communal roost of ravens in Thuringia, Germany, from August 2003 to January 2005. The number of roosting ravens
Main recommendations: Endoscopic mucosal resection (EMR) is the standard of care for the complete removal of large (≥ 10mm) nonpedunculated colorectal polyps (LNPCPs). Increased detection of LNPCPs owing to screening colonoscopy, plus high observed rates of incomplete resection and need for surgery call for a standardized approach to training in EMR. 1 Trainees in EMR should have achieved basic co
Proteins are not only important for our daily diet but also one of the most important food ingredients worldwide. Since the 1970ies membrane processes have established themselves as a key unit operation in protein processing, e.g., in the dairy industry. The recent trend of the protein shift moving consumption of animal-based to plant-based proteins provides new applications for membrane processes
Since some years ago greenhouse gases and especially carbon dioxide have become one of the most widely debated issues. To reduce the emission of carbon dioxide and nuclear waste, renewable energy sources as for example wind power plants have become very successful. These generation units are normally small compared to common thermal power plants and they are often placed distributed and connected
The drafters of the 1990 Dublin Convention knowingly and willfully disregarded divergences among Member States' protection systems. Like a boomerang, the fallacy of this approach has now reappeared in cases where asylum seekers have challenged transfers under the Convention, tasking judges to tackle a problem which its drafters avoided. The core issue of this article is whether and when such diver
DNA is presently at the centre of a storm. On the one hand, the breathtaking development of DNA related sciences during the last decades led to a technological and medical revolution. Due to the far reaching possibilities connected to this technology, it is the focus of many people’s interest and one source of the hope that one day we will find cures for terrible illnesses. Unsurprisingly, DNA re
We report on a theoretical study of the electronic structure of free-standing InAs and InP nanowires grown along the [100] crystallographic direction, based on an atomistic tight-binding approach. The band structure and wave functions for nanowires with both square (nanowires) and rectangular (nanobelts) cross sections are calculated. A comparison is made between the calculations for InAs, InP, an
The aim of this study is to demonstrate and evaluate the current anti-dumping law as formed by the WTO/GATT law (GATT law) and implemented by the EC law against the background of global economic integration. Over centuries, international trade has involved a controversial business behaviour, “dumping”. Roughly speaking, a product is considered to be dumped if it is sold at a lower price abroad tha
Popular Abstract in Swedish Växters artdiversitet i naturbetesmarker.Effekter av landskapsstruktur och habitathistoria. I min avhandling har jag undersökt växters artdiversitet i fragmenterade naturbetesmarker, av olika ålder och med olika historisk markanvändning. Jag har även undersökt betydelsen av habitatens isolerinsgrad i dagens och i det förflutna landskapet för dagens artdiversitet med häThe thesis examines the impact of present and past landscape structure, habitat history and management on different aspects of present-day plant species diversity in fragmented semi-natural grasslands in Sweden and in Estonia. Species diversity was significantly associated with present and/or past grassland connectivity in the majority of the studies in the thesis. However, relationships between
IntroductionCardiac surgery is required in up to half of the patients with infective endocarditis (IE). Positive valve cultures have been associated with higher in-hospital mortality. The aims were to identify risk factors for positive valve cultures and its relation to outcome.MethodsPatients subjected to heart valve cultures due to surgery for IE in Skåne University Hospital, Lund, between 2012
Radionuclides released and discharged into the environment from nuclear and other radiation-related facilities, such as the European Spallation Source (ESS), may accumulate in aquatic bottom sediments. Sediments should therefore, as recommended by the IAEA, be monitored regularly. This report describes the setting up of a methodology for zero-point assessments of the radiation levels in sediments
During recent years, the topic of corporate social responsibility has received a lot of attention. Within the field of research, the responsibilities of corporations have been discussed for decades, but no common ground and definition of the concept is in place. In today’s business context where the threat of climate change and other environmental challenges is growing, neither businesses nor cons
The regional planning office of Stockholm has pointed out eight core suburbs for the transition of suburbs into urban centers. The suburb of Täby is one of these. The transition implies changes on the fundamental components of place, the physical setting, its activities and meanings. The changes will affect citizens who spend their everyday life in Täby. Therefore, the essay has its starting point
