Insectivore classification has been one of the most controversial problems in mammalian systematics. Evolutionary relationships among the six extant families, Talpidae (moles), Soricidae (shrews), Erinaceidae (hedgehogs), Tenrecidae (tenrecs), Chryosochloridae (golden moles), and Solenodontidae (solenodons), have remained uncertain based on morphological data. Animals classified within the order L
E-procurement — e-business mechanisms deployed on procurement — offers many recent and innovative methods that can improve procurement in different ways. The key challenge of e-procurement, however, is how to apply the various e-procurement applications in such a way that they improve the procurement practice and sourcing strategy of a company. There is a demand for an investigation that scrutiniz
Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. As a consequence, numerous research programs concerning polymerization processes (e.g. emulsion po

The data consists of a series of observed music lessons, performances and stimulated recall interviews in two 8th form classes, video recorded in the course of one term. The analysis focuses on students’ and their tea
Popular Abstract in Swedish Syftet med studierna som presenteras i denna avhandling har varit att undersöka om fordonsetanol kan framställas på ett lönsamt och energieffektivt sätt från restprodukter från jord- och skogsbruk enligt svenska förhållanden. Mycket av den forskning som rör andra-generationens etanolproduktion går ut på att förfina och förbättra de separata delstegen i framställningsproSweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. A large amount of research has been devoted toward the development of sustainable
Popular Abstract in Swedish Asymmetrisk syntes för framställning av optiskt rena substanser är av stort intresse, inte bara för forskningsändamål utan även för praktiska tillämpningar inom flera olika branscher. Dagligen stöter man på produkter som har sitt ursprung i asymmetrisk syntes; allt från dofter, smakämnen och livräddande läkemedel till nya praktiska plaster med skräddarsydda egenskaper. In this work, the synthesis and characterisation of new low-valence transition metal carbonyl clusters, and an investigation into their viability to act as catalysts/catalyst precursors in asymmetric synthesis, are described. Carbonyl clusters based on ruthenium and osmium have been tested as (pre)catalysts for asymmetric hydrogenation of alpha-unsaturated carboxylic acids, and cobalt carbonyl clu
Deoxycytidine kinase (dCK) and deoxyguanosine kinase (dGK) catalyze the first step in the intracellular cascade of fludarabine (2-fluoroadenine-beta-D-arabinofuranoside) and cladribine (2-chlorodeoxyadenosine) phosphorylation, which leads to activation of these prodrugs, commonly used for treatment of chronic lymphocytic leukemia (CLL). Thus, resistance to nucleoside analogues may primarily be due
BACKGROUND: Pulmonary hypertension may result in significant morbidity and mortality after pediatric cardiac surgery. The objective of this study was to determine the incidence and outcome of severe pulmonary hypertension, defined as a ratio of pulmonary to systemic arterial pressure equal to or greater than 1.0, after cardiac surgery in children. METHODS: Data from all children younger than 18 ye
The drought of 2003 was exceptionally severe in many regions of Europe, both in duration and in intensity. In some areas, especially in Germany and France, it was the strongest drought for the last 50 years, lasting for more than 6 months. We used continuous carbon and water flux measurements at 12 European monitoring sites covering various forest ecosystem types and a large climatic range in ord
Popular Abstract in Swedish Denna avhandling är resultatet av min doktorandutbildning vid Kvartärgeologiska avdelningen, Geologiska institutionen, Lunds universitet. Avhandlingen baseras på pollenanlytiska undersökningar av ett antal lokaler i södra Sverige. I denna syntes sammanfattas resultaten av undersökningarna. Introduktion och bakgrund Avsikten med avhandlingen har varit att studera etabl
Background Systemic inflammation has been suggested to underlie in part the elevated risk of arrhythmias and myocardial dysfunction during the first weeks after cardiac surgery. Recent transthoracic Doppler studies from our centre indicated increased basal coronary arterial flow in children 5 days after cardiopulmonary bypass surgery. In these children, we investigated whether the inflammatory med
Background: Recent studies on the pathophysiology of heart failure indicate the role of neurohormones and immune and inflammatory processes as potential mechanisms involved in the pathogenesis and clinical course of chronic heart failure (CHF). Aim: To analyse the relationship between concentrations of brain natriuretic peptide (BNP), endothelin-1 (ET-1), inflammatory cytokines (TNF-alpha, IL-6) a
BACKGROUND: To investigate, in a rabbit model, the effect of two different doses of vigabatrin (VGB) on retinal function and morphology. METHODS: Twenty-nine rabbits of mixed strain were divided into two groups, receiving either high-dose (n = 15) or low-dose (n = 14) oral VGB treatment (cumulative dose 29.8 +/- 2.9 g and 14.2 +/- 0.6 g respectively). Ten rabbits receiving water served as control
Evidence suggests that in addition to sequestering carbon (C), biochar amendment can increase crop yields, improve soil quality and nutrient cycling, reduce the leaching of nutrients from soil and stimulate soil microbial activity. However, biochar application primarily benefits soils of intrinsic poor quality, thus the advantages of adding biochar to temperate agricultural soils remains controver
Objective To determine the diagnostic performance of ultrasound-based simple rules, risk of malignancy index (RMI), two logistic regression models (LR1 and LR2) and real-time subjective assessment by experienced ultrasound examiners following the exclusion of masses likely to be judged as easy and 'instant' to diagnose by an ultrasound examiner, and to develop a new strategy for the assessment of
BackgroundUnconscious survivors of out-of-hospital cardiac arrest have a high risk of death or poor neurologic function. Therapeutic hypothermia is recommended by international guidelines, but the supporting evidence is limited, and the target temperature associated with the best outcome is unknown. Our objective was to compare two target temperatures, both intended to prevent fever. MethodsIn an
Vertebral fracture risk is a heritable complex trait. The aim of this study was to identify genetic susceptibility factors for osteoporotic vertebral fracture applying a genome-wide association study (GWAS) approach. The GWAS discovery was based on the Rotterdam Study, a population-based study of elderly Dutch individuals aged >55 years; and comprising 329 cases and 2666 controls with radiographic
This report describes a model for the estimation of the time required to evacuate a building, by dividing the evacuation process into three phases: awareness, behaviour and response, and movement. The times required in each of these phases can be estimated separately and the sum then represents the total evacuation time. The time elapsed from the fire breaking out, to the discovery of the fire, is
Introduction. Along with the great expansion of research being published in Open Access (OA) journals over the last decade, the interest for analysing the OA literature using informetric methods has also increased. Most studies have focused on the citation impact of OA journals and whether OA publishing increases the chances of a research publication being cited. Fewer analyses, however, have inve
Popular Abstract in Swedish Alla levande organismer har DNA, och eftersom DNA är livsnödvändigt måste det repareras om det blir skadat. Ultraviolett (UV) strålning från solen är en av de vanligaste orsakerna till att DNA skadas. De flesta skador på DNA som orsakas av UV-strålning utgörs av cyklobutan-pyrimidindimerer (CPD) eller (6-4)-fotoprodukter. Dessa skador består av två intilliggande baser sAll living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair
