In order to prepare for the potentially negative influence of insertion devices (IDs) on beam lifetime, injection effi- ciency and beam size in the MAX IV 3 GeV storage ring, a strategy for neutralizing the foreseen effects of the IDs has been developed. The strategy involves a local correction of the betatron phase advance by adjusting the strength of the quadrupoles adjacent to the ID as well as

Methane is a powerful greenhouse gas and growing concern regarding global climate changes over the last years has pointed out the need to quantify and control the leaking of methane into the atmosphere. Landfill gas is regarded as one of the major sources for methane migration to the atmosphere. In this study we present research work with the objective to evaluate the use of geoelectrical resistiv

On St. Paul Island, a remnant of the Bering Land Bridge, woolly mammoths persisted until 5,600 yr BP with no known predators or competitors, providing a natural system for studying hypothesized environmental drivers of extinction. These include overheating due to rising temperatures, starvation, and drought. Here, we test these hypotheses using Niche Mapper and LPJ-GUESS to mechanistically estimat

Our understanding and quantification of global soil nitrous oxide (N2O) emissions and the underlying processes remain largely uncertain. Here, we assessed the effects of multiple anthropogenic and natural factors, including nitrogen fertilizer (N) application, atmospheric N deposition, manure N application, land cover change, climate change, and rising atmospheric CO2 concentration, on global soil

Although microfinance is often thought of as a tool to address poverty in developing countries, it is also being introduced in a number of countries in the developed world. The paper presents a qualitative study of the first year of the introduction of microfinance to address vulnerable groups in Sweden. Savings banks and nonprofit organisations collaborated in the introduction of microfinance as

Geophysical methods provide important information for mapping the subsurface. In semiarid areas, a detailed knowledge of the aquifers geometry can assist to a better management of groundwater. In the Valle Alto (Bolivia), which is a semiarid region, there is gap in the knowledge about the aquifer system geometry and hydrogeological processes. Local reports indicated problems in some wells such as

Carotenoid-based coloration in birds is widely considered an honest signal of individual condition, but the mechanisms responsible for condition dependency in such ornaments remain debated. Currently, the most common explanation for how carotenoid coloration serves as a reliable signal of condition is the resource trade-off hypothesis, which proposes that use of carotenoids for ornaments reduces t

Background: Quality of supervision is a major predictor for successful PhD projects. A survey showed that almost all PhD students in the Health Sciences in Denmark indicated that good supervision was important for the completion of their PhD study. Interestingly, approximately half of the students who withdrew from their program had experienced insufficient supervision. This led the Research Educa

Complement is crucial to the immune response, but dysregulation of the system causes inflammatory disease. Complement is activated by three pathways: classical, lectin, and alternative. The classical and lectin pathways are initiated by the C1r/C1s (classical) and MASP-1/MASP-2 (lectin) proteases. Given the role of complement in disease, there is a requirement for inhibitors to control the initiat

The number of triangulations of a planar n point set S is known to be cn, where the base c lies between 2.43 and 30. Similarly, the number of crossing-free spanning trees on S is known to be dn, where the base d lies between 6.75 and 141.07. The fastest known algorithm for counting triangulations of S runs in 2(1+o(1))nlog n time while that for counting crossing-free spanning trees runs in O (7.12

Global gene expression analysis has been a major tool for urothelial carcinoma subtype discovery. This approach has revealed extensive complexity both in intrinsic features of the tumor cells and in the microenvironment. However, global gene expression cannot distinguish between gene expression signals originating from the tumor cells proper and from normal cells in the biopsy. Here, we use a larg

Mankind has faced a huge increase in severe natural and man-made disasters worldwide in the last few years. Emergency responders on a strategic, tactical, and operational level can be assisted by decision support systems (DSS) to enhance disaster preparedness, response, and recovery. Policy makers are in need of an advanced, resilient and integrated incident command and control systems for emergen

In the recovery phase after a radioactive release incident, it is important to be able to focus decontamination operations on the areas that contribute most to the radiation dose. Monte Carlo simulations were applied to determine the shielding effect of a building against radiation from various directions, also giving information on the dose contributions at various locations inside the building f

The need for frequent retreatment is a disadvantage of using endoscopic laser therapy (ELT) alone for palliative treatment of esophageal carcinoma. In this prospective study, therefore, we investigated the potential and feasibility of combining ELT with a self-expanding metallic stent (Wallstent). Twelve patients received ELT followed by stent placement (stent group) and were compared with 39 pati
