Structural and magnetic dynamics in the magnetic shape-memory alloy Ni2MnGa

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

Do spinoff dynamics or agglomeration externalities drive industry clustering? A reappraisal of Steven Klepper's work

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 commissioning and calibration

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

Micronuclei in Cord Blood Lymphocytes and Associations with Biomarkers of Exposure to Carcinogens and Hormonally Active Factors, Gene Polymorphisms, and Gene Expression: The NewGeneris Cohort

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

Inadvertent arterial catheterization complicating femoral venous access for haemodialysis

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

The drumlin problem : streamlined subglacial bedforms in southern 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

The role of Moraxella catarrhalis outer membrane proteins in pathogenesis

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.

Empirical Equations for Intrinsic and Effective Evaporative Resistances of Multi-layer Clothing Ensembles

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

End-stage renal disease and low level exposure to lead, cadmium and mercury; a population-based, prospective nested case-referent study in Sweden

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

Naming me, naming you. Personal names, online signatures and cultural meaning

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

Interreligiösa gruppers samarbete med kommuner i Sverige

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

The grey partridge and AESs in Sweden: Setting up an experimental restoration of the grey partridge and associated farmland biodiversity in Sweden

The grey partridge Perdix perdix has suffered a severe decline in numbers and contraction in range during the last half century. The loss of landscape heterogeneity through agricultural intensification has often been indicated as a cause. By preserving and managing small biotopes and creating uncropped border zones, some ecological heterogeneity is maintained and recreated with the aid of agri-env

Photovoltaics with Piezoelectric Core-Shell Nanowires

We report on a theoretical discovery of a generic piezoelectric held in strained core shell compound semiconductor nanowires. We show, using both an analytical model and numerical simulations based on fully electroelastically coupled continuum elasticity theory, that lattice-mismatch-induced strain in an epiraxial core shell nanowire gives rise to an internal electric held along the axis of the na

Beroendevård i socialtjänst och sjukvård - En svensk modell att utmana.

Addiction treatment often requires medical, psychosocial and social expertise - and benefits from collaboration. The pronounced role of social authorities in evaluation and treatment is unique to the addiction field. Unified responsibility for evaluation and treatment of addiction is under consideration. Treatment of psychiatric and physical co-morbidity benefits from a unified responsibility with
