Doping mechanisms of Mn in GaAs nanowires (NWs) that have been grown self-catalytically at 600 degrees C by molecular beam epitaxy (MBE) are investigated using advanced electron microscopy techniques and atom probe tomography, Mn is found to be incorporated primarily in the form of non-magnetic tetragonal Ga0.82Mn0.18 nanocrystals in Ga catalyst droplets at the ends of the NWs, while trace amounts
A thorough understanding of how proteins induce nanoparticle (NP) aggregation is crucial when designing in vitro and in vivo assays and interpreting experimental results. This knowledge is also crucial when developing nano-applications and formulation for drug delivery systems. In this study, we found that extraction of immunoglobulin G (IgG) from cow serum results in lower polystyrene NPs aggrega
Semiconductor nanowires composed of III-V materials have enormous potential to add new functionality to electronics and optical applications. However, integration of these promising structures into applications is severely limited by the current near-universal reliance on gold nanoparticles as seeds for nanowire fabrication. Although highly controlled fabrication is achieved, this metal is entirel
BACKGROUND: Few studies investigate predictors of intentional self-injury over time in non-clinical samples. By using longitudinal data from the whole population of the county of Scania, Sweden, aged 18 years and over (N = 936 449), we aim to identify risk factors for non-fatal diagnosed intentional self-injury. Groups at risk of repeat episodes of self-injury will be identified. METHODS: Informat
Long-term oxygen therapy (LTOT) improves the survival time in hypoxemic chronic obstructive pulmonary disease. Despite warnings about potential dangers, a considerable number of patients continue to smoke while on LTOT. The incidence of burn injuries related to LTOT is unknown. The aim of this study was to estimate the rate of burn injury requiring health care contact during LTOT.
In the Swedish crisis management system, the municipalities have a great responsibility. One part of this responsibility concerns preparing for crises by making risk and vulnerability analyses as well as plans for how to handle extraordinary events. Such preparedness planning involves municipal officials and consequently their conceptions of their organisations’ crisis management capabilities. Thi
Transitioning into retirement is an under-researched phenomenon in developing countries. Largely, this is linked to a predominance of contexts where –in particular –the rural population remains outside the coverage of any formal pension system. In 2008, China introduced the New Rural Social Pension (NRSP), a program which by now covers the majority of the Chinese rural elderly. This paper examines
Fighting infectious disease in the past, much like today, focused on isolating the disease and thereby stopping its spread. New insights into the modes of transmission and the causal agents in the mid-nineteenth century, together with fear of new epidemic outbreaks, motivated public investments aimed at reducing mortality from infectious disease. Combining longitudinal individual-level data on 17,
Background: In Sweden, a person with substance abuse can be reported to the social services for an investigation about commitment to coercive care. After a change in legislation, municipalities varied greatly in the ratio of commitments/reports compared with the period before the legislation was amended. Aims: The primary aims of this study were first, to investigate whether subjects from municipa
PURPOSE:: To investigate concordance between objective and perceived neighborhood walkability, their associations with self-reported walking and objective physical activity, and sociodemographic characteristics of individuals in neighborhoods with objectively assessed high walkability who misperceive it as low. METHODS:: In 1,925 individuals aged 20-66 years, recruited from administrative areas in
Background: The coding of histology of nervous system (NS) tumors with various degrees of malignancies differs between cancer registries, whereby the comparison of incidence rates from one registry to another seems difficult. No study has systematically defined whether the change in the risk of NS tumors upon immigration in adulthood varies by subsite or histology. Therefore, we aimed to address t
BACKGROUND: The incidence of acute cardiovascular and cerebrovascular events in patients treated for complicated or uncomplicated peptic ulcer disease (PUD) has not been ascertained completely. METHOD: All patients with in-hospital treatment due to PUD between 1987 and 2007, who did not have any past history of acute or chronic cardiovascular or cerebrovascular disease, were identified through the
Background/Aims: Motor impairment is an important aspect of cognitive decline in older adults. It has been suggested that complex motor control is affected earlier than gross motor control. The aims were to investigate if complex hand motor function was more affected than gross motor function in cognitively impaired older subjects, and to present reference values. Methods: Alternating forearm move
BACKGROUND: Cancer and venous thromboembolism (VTE) are associated disorders. In the present nationwide study, we analyzed the risk of cancer in siblings, offspring and spouses of individuals hospitalized for VTE (and vice versa) with the aim of identifying shared familial risk factors for cancer and VTE. MATERIAL AND METHODS: The Multigeneration Register was linked to the Swedish Hospital Dischar
Objective: Previous studies suggest that low birth weight is associated with thyroid autoimmunity and hypothyroidism in later life, but the potential effect of preterm birth, independent of fetal growth, is unknown. Our objective was to determine whether preterm birth is independently associated with medically treated hypothyroidism in young adulthood. Design/Participants: National cohort study of
