The objective of this study was to assess the reciprocal association between non-Hodgkin lymphoma (NHL) and Merkel cell carcinoma (MCC) using the data of four Nordic Cancer Registries. Data for this study were drawn from the Danish, Finnish, Norwegian, and Swedish cancer registries. Standardized incidence ratios (SIRs) for MCC among NHL patients, and for NHL among MCC patients, were calculated. Th
The large bloom-forming flagellate Gonyostomum semen has been hypothesized to be inedible to naturally occurring zooplankton due to its large cell size and ejection of long slimy threads (trichocysts) induced by physical stimulation. In a grazing experiment using radiolabelled algae and zooplankton collected from lakes with recurring blooms of G. semen and lakes that rarely experience blooms, we f
We establish a new mechanism for self-propelled motion of droplets, in which ordering of the nanoscale step morphology by sublimation beneath the droplets themselves acts to drive them perpendicular and up the surface steps. The mechanism is demonstrated and explored for Ga droplets on GaP(111)B, using several experimental techniques allowing studies of the structure and dynamics from micrometers
During the years 2006 to 2009, Rare Isotope Spectroscopic INvestigations at GSI (RISING) have focused on high-resolution gamma-ray spectroscopy of exotic nuclear species at rest: following unambiguous discrimination and identification by the FRagment Separator (FRS) and its suite of detectors, the nuclei of interest were implanted in either a passive stopper or a stack of silicon detectors to allo
BACKGROUND: Intense exercise has been reported as one risk factor for hip and knee osteoarthritis (OA). PURPOSE: This study aimed to evaluate (1) whether this is true for both former impact and nonimpact athletes, (2) if the risk of a hip or knee arthroplasty due to OA is higher than expected, and (3) if joint deterioration is associated with knee injuries. STUDY DESIGN: Cohort study; Level of evi
Introduction. Palliative cancer care in acute hospitals is scarcely studied. We therefore described and compared symptoms, care needs and types of cancer sites in 2002 compared to 2007 and analysed the relationships between these factors. Methods. The study was population-based with a cross-sectional design and was carried out in medical, surgical and oncology wards in two acute care hospitals wit
The purpose of the present study was to investigate the relationship between perception and production of metrical patterns in Swedish children with language impairment (LI), in order to add to the knowledge on underlying explanations of LI. A further aim was to explore whether omissions are mainly related to prosodic aspects or to linguistic function. Children with LI omitted significantly more u
Seed particles of elements or compounds which may or may not form alloys are now used extensively in promoting well-controlled nanowire growth. The technology has evolved following the well-known Vapour-Liquid-Solid (VLS) model which was developed over 40 years ago. This model indicates that a liquid alloy is formed from the seed particle and the growth precursor(s), resulting in crystal growth by
This paper presents a computational study of the effects of fuel and thermal stratifications on homogenous charge compression ignition (HCCI) combustion process in a personal car sized internal combustion engine. Stratified HCCI conditions are generated using a negative valve overlap (NVO) technique. The aims of this study are to improve the understanding of the flow dynamics, the heat and mass tr
This article deals with asset correlation estimation among firms with foreign exchange exposure. In most credit risk models the exchange rate risk is ignored, i.e. the borrowing firms are supposed to have assets denominated in the same currency as their debt. In reality, this is often not the case and if the asset portfolios of two borrowers are exposed to foreign exchange risk the correlation bet
Även parker kan vara tämligen artrika och hysa rödlistade arter. Nedan redovisar Ulf Arup resultatet av en inventering av Lunds stadspark, som trots att den är omgiven av vägar med delvis stark trafik uppvisar en god artrikedom.
An efficient and selective isomerization of 1-alkenes to their corresponding 2-alkenes is achieved by using binary metal carbonyls such as Ru-3(CO)(12) as catalysts. Possible mechanisms are discussed. Substituents on the 1-alkene have a significant effect on the isomerization. (C) 2008 Elsevier Ltd. All rights reserved.
Bacterial infections are a major global threat to public health and sepsis is a major cause of morbidity and mortality. Sepsis incidence is rising, with supportive treatments and antibiotics being the main treatment possibilities. Sepsis is characterised by an excessive and uncontrolled immune and coagulation response, leading to tissue damage, capillary leakage, and multiple organ failure. Althou
Accumulated carbon uptake, apparent quantum yield (AQY) and light-saturated net CO2 assimilation (A(sat)) were used to assess the responses of photosynthesis to environmental conditions during spring for three consecutive years. Whole-tree chambers were used to expose 40-year-old field-grown Norway spruce trees in northern Sweden to an elevated atmospheric CO2 concentration, [CO2], of 700 mu mol C
Purpose – The purpose of this paper is to examine and analyze the prevailing form of rationality that governs the challenges, goals and roles of communication professionals. The authors will also explore alternative forms of rationality and discuss what these would imply. Design/methodology/approach – The paper is based on survey results from The European Communication Monitor (ECM) and qualitativ
Abstract in UndeterminedYou may think that your requirements engineering process is fairly limited and currently not too complex to manage. Or you may be right in the middle of a storm of requirements where it is impossible to manage even the most important ones comprehensively. If you are in the former situation, it may be dangerous to relax as many successful software-intensive products have a t
Abstract The aim of the thesis has been to explore representations of gender, ethnicity and generation in school readers used in the Swedish compulsory school since 1962, to find which ’discourses’, linked to equal opportunities, integration/diversity and childhood, underlie these constructions, and in which ways they may have contributed to the (re)production of different gendered, ethnified and
Abstract in UndeterminedWe suggest a new way of modeling the dynamics of a firm’s asset value and discuss how it could be useful in the computation of asset value correlations in multivariate credit risk models. The method relies on credit spreads from the credit default swap market and by combining these spreads with stock prices and leverage ratios we show how one can construct a proxy for the a
