The particle formation and growth events observed at a semirural background site in Denmark were analyzed based on particle number size distribution data collected during the period from February 2005 to December 2010. The new particle formation (NPF) events have been classified visually in detail according to 3D daily plots in combination with an automatic routine. A clear seasonal variation was
A small fraction of the halo field is made up of stars that share the light element (Z <= 13) anomalies characteristic of second generation globular cluster (GC) stars. The ejected stars shed light on the formation of the Galactic halo by tracing the dynamical history of the clusters, which are believed to have once been more massive. Some of these ejected stars are expected to show strong Al enha
Software failures in medical devices can lead to catastrophic situations. Therefore is it crucial to handle software related risks when developing medical devices. This paper presents the experiences gained from an ongoing case study with a medical device development organisation. This part of the study focuses on the two first steps of the risk management process, i.e. risk identification and ris
Chronic migraine (CM) is a type of chronic daily headache. CM presents a challenge to primary care physicians and neurologists. Any new treatment showing efficiency would therefore be of great importance. Atenolol together with other beta-blockers is a first-line choice in episodic migraine prophylaxis. Clinical findings support the efficacy of atenolol in doses of 50 to 200 mg/day.
The Swedish reimbursement system operates a system where prices are set based on the expected value to the consumer. This value can be measured using willingness to pay (WTP).
Using a simplified model for in-medium dipole evolution accounting for color filtering effects we study the production of hadrons at large transverse momenta p(T) in heavy ion collisions. In the framework of this model, several important sources of the nuclear suppression observed recently at RHIC and LHC have been analyzed. A short production length of the leading hadron l(p) causes a strong onse
The Starmoen dune field is part of a larger aeolian system in the Jomna and Glomma river valleys in southeastern Norway. It is believed to have formed just after the last deglaciation in the area, but no absolute ages have been available to support this. Here, we present a set of quartz optically stimulated luminescence (OSL) ages from the aeolian sediments and the underlying glacifluvial deposits
Context The evidence that measurement of the common carotid intima-media thickness (CIMT) improves the risk scores in prediction of the absolute risk of cardiovascular events is inconsistent. Objective To determine whether common CIMT has added value in 10-year risk prediction of first-time myocardial infarctions or strokes, above that of the Framingham Risk Score. Data Sources Relevant studies we
The aim of this contribution is partly to build consensus on a consistent modelling methodology (CMM) of complex real processes in wastewater treatment by combining classical concepts with results from applied mathematics, and partly to apply it to the clarification-thickening process in the secondary settling tank. In the CMM, the real process should be approximated by a mathematical model (proce
The central role of bone morphogenetic proteins (BMPs) in the remodelling process of the human skeleton has been identified in numerous experimental and clinical studies. BMPs appear to be key agents in the osteoblastic differentiation of mesenchymal stem cells, and more recent evidence implicates them with the cells of the osteoclastic lineage. BMP-2, BMP-4, BMP-6 and BMP-7 have been studied in t
This study compares the children and adult response to a novel postural challenge. One group of children (n = 13, age 7-9) and one adult reference group (n = 12 age 15-32) were subjected to vibration induced body sway and posturography with both open and closed eyes for 5 consecutive days. There was a gradual decrease of induced body sway over time in both groups (p < 0.001) between the subsequent
The economic development in the world today makes increased consumption of goods and travelling available for more people around the world than ever before. This results, however, also in increased production and spreading of substances that are hazardous both to human health and to the ecosystem globally. Therefore, education to increase knowledge, awareness, motivation, and action competence on
In order to contribute to knowledge on how-to expand bioenergy this paper examines an example of success from Sweden. The idea is to identify factors that can explain the difference between success and failure of bioenergy systems. In the aftermath of the oil crises in the 1970s, the local government in the town of Enkoping in Sweden was cautioned by the local Swedish military regiment to shift to
Vascular injuries operated on during a 30-year period (1955-1984) were analyzed. There has been significant increase of such injuries, particularly the iatrogenic types. The total incidence per 100,000 population and year rose from 11.0 to 26.6. Various angiographic and catheterization techniques were responsible for the iatrogenic increase. The noniatrogenic vascular injuries not infrequently wer
We have used suramin and brefeldin A to investigate the nature of a heparan sulphate proteoglycan that appears to recycle from the cell surface to intracellular compartments which synthesize new heparan sulphate chains. Suramin, which would block internalization and deglycanation of a putative recycling cell surface proteoglycan, markedly increases the yield of a membrane-bound proteoglycan with a
