Popular Abstract in Swedish Stora framsteg har gjort det möjligt att, med dagens teknik, inte bara visualisera enskilda atomer, utan även utföra olika typer av operationer och manipulationer på atomskalan med stor precision rent experimentellt. Detta har möjliggjort tillverkning av komplexa nanostrukturer genom montering av komponenter av nanostorlek till större sammansatta system, vilket i sin tuNanowires constitute one of the fundamental building blocks in assembled nanodevices. Due to the high surface to volume ratio, the fraction of surface atoms is not negligible for nanosized elements. Because of the reduced coordination of surface atoms, the physical properties deviate from those of the bulk, which influences the overall physical properties of nanostructures. Consequently, this prov
Background The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age-sex groups, and countries. The GBD can be used to generate summary measures such as disability-adjusted life
Background: Obstetrical anal sphincter injuries are complications of vaginal birth that have the potential to cause substantial maternal morbidity. Predicting these injuries might help to improve maternal care as well as antenatal counseling and patient education. Previous attempts to create prediction models have in many cases involved variables only known postpartum, which limits their use in an
Background: Epidemiological studies that assess the health effects of long-term exposure to ambient air pollution are used to inform public policy. These studies rely on exposure models that use data collected from pollution monitoring sites to predict exposures at subject locations. Land-use regression (LUR) and universal kriging (UK) have been suggested as potential prediction methods. We evalua
Increased QT dispersion and loss of sinus rhythm were both associated with sudden cardiac death in patients with transposition of the great arteries after Mustard and Senning operations at the early and late postoperative periods. A combination of increased QT dispersion with loss of sinus rhythm increases the positive predictive value for sudden cardiac death in patients with transposition of the
Occlusion is the most common reason for lowered recognition yield in free-flow license-plate reading systems. (Non-)occluded characters can readily be learned in separate neural networks but not together. Even a small proportion of occluded characters in the training set will already significantly reduce the overall recognition yield. This paper shows that a modular network can handle a realistic
OBJECTIVE: To determine what constitutes normal cervical changes during the second half of pregnancy in parous women delivering at term. DESIGN: The study comprises 21 healthy, pregnant parous women who all gave birth at term. They were examined with transvaginal ultrasound every two weeks from 24 gestational weeks until delivery. Cervical length and width were measured. The inner cervical os was
ABSTRACT Background: A Quick Test of Cognitive Speed (AQT) is a brief test that can identify cognitive impairment. AQT has been validated in Arabic, English, Greek, Japanese, Norwegian, Spanish, and Swedish. The aim of this study was to develop Italian criterion-referenced norms for AQT. Methods: AQT consists of three test plates where the patient shall rapidly name (1) the color of 40 blue, red,
Popular Abstract in Swedish Under det senaste decenniet har risker med och alternativ till allogent blod (blod från främmande givare) debatterats mycket pga. risken för smitta, allergiska reaktioner, samt starka indicier som talar för att blod från främmande givare kan påverka immunförsvaret hos mottagaren. Därför vill man gärna begränsa mängden tillfört givarblod under kirurgiska ingrepp på barn,In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23
The online-coupled 3-D chemistry transport model COSMO-MUSCAT was enhanced by a detailed description of aqueous phase chemical processes. The aqueous phase chemistry is represented by the detailed chemical mechanism CAPRAM 3.0i reduced (C3.0RED). In addition, the deposition schemes were improved in order to account for the deposition of matter incorporated in cloud droplets of ground layer clouds
There is a scarcity of instruments for assessing opportunities for residentswith psychiatric disabilities to engage in meaningful home-based activities.We thus developed the Perceived Meaning of Activity in Housing (PMA-H),containing four subscales (activity opportunities, social interaction, developingas a person, and organization and planning). The aim of the study was to investigate the content
These guidelines are for practicing orthopedic surgeons who do not have a special interest in treatment of osteoporosis or prevention of falls, but who should have basic knowledge about how to prevent new fractures.
BACKGROUND: Parkinson's disease is typically treated with oral dopamine replacement therapies; however, long-term treatment leads to motor complications and, occasionally, impulse control disorders caused by intermittent stimulation of dopamine receptors and off-target effects, respectively. We aimed to assess the safety, tolerability, and efficacy of bilateral, intrastriatal delivery of ProSavin,
This report presents basic concepts around resources, resource efficiency and the Circular Economy. The limitations and the opportunities within the Circular Economy are identified and clearly presented. The current policy landscape in the EU as well as in Sweden is thoroughly analysed and a set of policy areas with a significant untapped potential for resource efficiency is identified. The policy
The study of airborne bacteria relies on a sampling strategy that preserves their integrity and in situ physiological state, e.g. viability, cultivability, metabolic activity, and ice-nucleation activity. Because ambient air harbors low concentrations of bacteria, an effective bioaerosol sampler should have a high sampling efficiency and a high airflow. We characterize a high-flow-rate impinger wi
Objective: Studies of the importance of perinatal factors for the development of irritable bowel syndrome (IBS) are sparse. We conducted a large national cohort study to examine perinatal and familial risk factors for IBS. Material and methods: A national cohort of 1,963,685 persons who were born in Sweden in 1973–1992 (identified from the Swedish Birth Registry) were followed up for adult (18 yea
