Life on Earth was sharply disrupted 66 Ma ago as an asteroid hit the sea-floor in what is today Yucatan Peninsula, Mexico. Approximately 600 km(3) of sedimentary rock were vapourized, ejected into the atmosphere and subsequently deposited globally as an ejecta apron and fallout layer. Proximal ejecta deposits occur in Belize and southern Mexico where the so called Albion island spheroid bed is sup

BACKGROUND: Antimicrobial peptides (AMPs) are important actors in the innate immune system. One class of AMPs is the human β-defensins (HBDs), a group of small peptides with a broad spectrum of antimicrobial activities. Expression of HBDs is downregulated in different manifestations of allergic disease. In this study, we examine whether allergen-specific immunotherapy (ASIT) affects the nasal leve

Objective: To compare the efficacy and side effects of intermittent pulse cyclophosphamide plus methylprednisolone with continuous oral cyclophosphamide plus prednisolone, followed by azathioprine, in patients with proliferative glomerulonephritis caused by systemic lupus erythematosus (SLE). Methods: A multicentre randomised controlled trial was conducted between June 1992 and May 1996 involving

Bone mineral density (BMD) measurements are widely used to estimate the risk of osteoporotic fractures. In addition, many other risk factors have been identified, sonic of which are known to add to the risk independently of BMD measurements. The combination of BMD with such risk factors increases the gradient of risk/standard deviation (SD) than that achieved by BMD alone. In this paper, we report

Fair use is a doctrine native to the U.S., but is with the introduction of the internet more than a decade ago now informally applied worldwide. It has become a potent tool for the digitisation of classic content, such as books and music. In a very debated area of law, copyright is now regarded not as a promotional tool for intellectual endeavours, but as a brake block obstructing the development

We have previously demonstrated an association between neonatal phototherapy and/or neonatal icterus and risk of hospitalization for childhood asthma. This study included children who were prescribed anti-asthmatic medication on a population basis to study exposures during the foetal and neonatal period and risk of childhood asthma. The Swedish Medical Birth Register was linked to the Swedish Pres

Laminar burning velocities of syngas/air premixed flames, varying with H-2/CO ratio (from 5/95 to 75/25) and N-2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich.

Objective: To study prescription patterns of biological treatment in rheumatoid arthritis ( RA) patients in southern Sweden, a region with no formal or economic restrictions for the use of biological treatment in rheumatological diseases. Specifically, we studied conformity with the national Swedish guidelines for biologics in RA. Methods: Rheumatologists in southern Sweden contribute to a volunta

Objectives: To describe the intake of vitamins thiamine (B1), riboflavin (B2), B6 (pyridoxine), B12 (cobalamine) and C (ascorbic acid) and their food sources among 27 centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Between 1995 and 2000, 36 034 persons aged between 35 and 74 years were administered a standardized 24-h

P>Regional transplant practices may affect clinical outcomes within multinational studies. This study evaluated whether the overall results from the Symphony study can be generalized to the participating countries. De novo adult renal transplant recipients (n = 1645) were randomized to receive standard-dose cyclosporine, or daclizumab induction plus low-dose cyclosporine, low-dose tacrolimus, or l

The morbidity of bone fractures and defects is steadily increasing due to changes in the age pyramid. As such, novel biomaterials that are able to promote the healing and regeneration of injured bones are needed to overcome the limitations of auto-, allo-, and xenografts, while providing a ready-to-use product that may help to minimize surgical invasiveness and duration. In this regard, recombinan

Platelet P-selectin and activated glycoprotein IIb–IIIa (GPIIb–IIIa) are markers of platelet activation and mediates platelet aggregation. Prasugrel (Pras) 5 mg may be used in very elderly (VE) acute coronary syndrome (ACS) patients undergoing PCI, but its effect on platelet P-selectin and activated GPIIb–IIIa in those patients is not known. Stable ACS patients, VE (78 ± 5 years, n = 23) and non-e

Title: The role and status of music theory ? an inquiry into the Arts Programme of the Swedish upper secondary school. The purpose of this inquiry is to find out what teachers of the Arts Programme say about the role and status of music theory within the different music subjects. Four teachers were interviewed, two teachers of music theory and two instrumental teachers. The interviews were formula

With constant upgrades in 3d-modeling software, even previously functional and validated animated facial expressions can be updated. The present work seeks to provide such an additional upgraded set of tools for researchers to use interested in e.g. emotional facial expressions, and contains two experiments. One where static facial expressions are tested in three different ways and a second experi

The need for cost-effective linear motion is large in all sectors of industry and the linear actuator is one of the responses to this need. The purpose of this thesis was to search for alternative linear technologies to replace a pneumatic cylinder. The cylinder had certain attributes which the new technology had to reproduce. In order to attain all of these attributes a list of specifications fo

Autofokus för elektroner Människan har alltid varit intresserad av att studera förlopp som skett så snabbt att de inte gått att observera med blotta ögat. Med hjälp av kameror med korta slutartider kan man frysa ett ögonblick i tiden. Processer i atomer och molekyler sker på en helt annan tidsskala än den vi är vana att fotografera. Atomerna lever i en värld där saker sker så fort att man behöverConclusion The results from the optimization with GA shows that there is no noticeable difference between optimizing for arithmetic and geometric mean of the resolution. The idea behind using the geometric mean is that it would lend smaller importance to outlier values. Both settings found about the same range of values for VBend, VTweak and VExt, with comparable standard deviations. When optimiz
