The possibility to reduce dependence on fossil fuel resources has led to an increasing interest in the use of bio-fuels. This study builds on earlier work on (aromatic) cyclic oxygenates [1,2], but a far wider window of engine operation has been investigated in this paper. Two parametric variations of engine operation were performed and discussed: (1) non-EGR operation by means of varying the load
Statement of Interest Assessment of visual field damage is the major index of the functional impact of glaucoma with direct relevance to quality of life measures. Visual field change was used as a primary endpoint for progression in the recent glaucoma trials and its measurement is the cornerstone of glaucoma management influencing therapeutic decisions. The objective of this perspective is to pro
During 2007 and 2008 the speed limits 40 och 60 km/h have been tried out in twelve Swedish cities, out of which six have participated in a evaluation in this project, financed by the Swedish National Road Administration. The evaluation has focused on effects from the changes in speed limits on actual speeds, safety, environment and travel times, as well as the attitudes towards the new speed limit
While the advancement in semiconductor technologies enables manufacturing of highly advanced and complex integrated circuits, there is an increasing need of embedded (on-chip) instruments for test, debug, diagnosis, configuration, monitoring, etc. A key challenge is how to access these instruments from chip terminals in a low-cost, non-intrusive, standardized, flexible and scalable manner. The wel
Objectives: The aim of this study was to assess acute health effects on planters caused by planting conifer seedlings treated with two insecticides, with active ingredients imidacloprid and cypermethrin, in comparison with untreated seedlings. Methods: The investigation was a double-blind crossover study, which included a follow-up of 19 planters over a 3-week period. During Week 1, the 19 planter
Magnetic shape-memory Heusler alloys are multiferroics stabilized by the correlations between electronic, magnetic, and structural order. To study these correlations we use time-resolved x-ray diffraction and magneto-optical Kerr effect experiments to measure the laser induced dynamics in a Heusler alloy Ni2MnGa film and reveal a set of time scales intrinsic to the system. We observe a coherent ph
Steven Klepper's theory of industry clustering based on organizational reproduction and inheritance through spinoffs challenged the Marshallian view on industry clustering. This article provides an assessment of Klepper's theoretical and empirical work on industry clustering. We explore how "new" his spinoff theory on industry clustering was, and we investigate the impact of Klepper's theory on th
The ATLAS Inner Detector is a composite tracking system consisting of silicon pixels, silicon strips and straw tubes in a 2 T magnetic field. Its installation was completed in August 2008 and the detector took part in data-taking with single LHC beams and cosmic rays. The initial detector operation, hardware commissioning and in-situ calibrations are described. Tracking performance has been measur
Background: Leukemia incidence has increased in recent decades among European children, -suggesting that early-life environmental exposures play an important role in disease development. Objectives: We investigated the hypothesis that childhood susceptibility may increase as a result of in utero exposure to carcinogens and hormonally acting factors. Using cord blood samples from the NewGeneris coh
Objective. Large-bore catheters for temporary haemodialysis are often placed via the internal jugular or femoral vein, guided by external landmarks or ultrasound techniques. Inadvertent femoral artery catheterization may occur during attempted placement of the dialysis catheter in the femoral vein. Material and methods. This investigation was carried out in Skane University Hospital, Malmo, Sweden
Popular Abstract in Swedish Denna avhandling behandlar strömlinjeformade subglaciala bäddformer (ofta kallade drumliner) i södra Sverige. Det övergripande syftet med denna studie är att bidra till en lösning av det så kallade ”drumlinproblemet”. Termen drumlin har kommit att tillämpas på en grupp av landformer vars interna sediment, strukturella uppbyggnad och yttre form kan variera kraftigt. DessThis thesis investigates stream-lined subglacial bedforms (often referred to as drumlins) in southern Sweden. The broad aim of this is to contribute to the solution of the ‘drumlin problem’. The term drumlin has come to be applied to a wide range of features whose internal architecture (core) and overall morphology are seen to vary greatly. This range in characteristics is in part responsible for
Moraxella catarrhalis is an important respiratory pathogen. It is a common cause of otitis media in children, a usual infections agent in sinusitis and makes up to 10% of all exacerbations of chronic obstructive pulmonary disease (COPD). It is known to cause more frequent disease in the colder season, and, generally, its importance is recognised mainly in countries exposed to moderate climate. M.
To determine the intrinsic and effective clothing evaporative resistances,both in the individual clothing, and in the nulti-layer clothing ensembles meant for winter season, a fabric sweating thermal manikin Walter was used. Based on the tests performed on the individual garments, two empirical equations were developed for the estimation of these resistances, useful either to clothing manufacturer
Background: Cadmium (Cd), lead (Pb), and mercury (Hg) cause toxicological renal effects, but the clinical relevance at low-level exposures in general populations is unclear. The objective of this study is to assess the risk of developing end-stage renal disease in relation to Cd, Pb, and Hg exposure. Methods: A total of 118 cases who later in life developed end-stage renal disease, and 378 matched
Every day we talk and speak and chat to people. We write and listen to each other, refer to each other, describe to each other what we and others have done and said. Doing this, we sometimes use our given names, sometimes we go by our nicknames, which often indicate or clarify who we are or are made up by ourselves to draw other people’s attention. Nicknames can be official or informal, known by m
In Swedish contemporary society we find ongoing processes of secularization and the idea of secularism being challenged by a growing religious plurality in society. The overall purpose of this article is to highlight what happens when religion in a secularized and secular society enter into the public sphere as a result of inter-religious groups’ collaboration with local authorities. This is done
