This review provides a comprehensive account of what is known presently about Amazonian aerosol particles and concludes by formulating outlook and priorities for further research. The review is organized to follow the life cycle of Amazonian aerosol particles. It begins with a discussion of the primary and secondary sources relevant to the Amazonian particle burden, followed by a presentation of t
Targino, A. C., Krecl, P., Johansson, C., Swietlicki, E., Massling, A., Coraiola, G. C. & Lihavainen, H. 2013: Deterioration of air quality across Sweden due to transboundary agricultural burning emissions. Boreal Env. Res. 18: 19-36. We analyzed measurements of aerosol and trace-gas concentrations from sites across Sweden before and during a series of agricultural wildland fires in eastern Eu
This article reports the findings of what it means to live with intestinal failure caused by Crohn disease and how it influences daily life. Ten patients, 7 with an ostomy and 7 on home parenteral nutrition followed up at an outpatient clinic for patients with intestinal failure, were interviewed using a qualitative, phenomenological-hermeneutic method. The analysis of the transcribed data is desc
OBJECTIVES: To examine patient willingness and possible shift in willingness for surgery and to investigate factors associated with this shift, following participation in the digital non-surgical osteoarthritis (OA) treatment program Joint Academy.METHODS: 458 individuals (mean age 62±5.6 years, 67% women) with diagnosed hip or knee were evaluated after six weeks in Joint Academy, comprising educa
Immunophenotypic characterization and molecular analysis have long been used to delineate heterogeneity and define distinct cell populations. FACS is inherently a single-cell assay, however prior to molecular analysis, the target cells are often prospectively isolated in bulk, thereby losing single-cell resolution. Single-cell gene expression analysis provides a means to understand molecular diffe
Study region: The Limpopo River Basin (LRB) is a transboundary catchment in Southern Africa, shared by South Africa, Botswana, Zimbabwe, and Mozambique. The basin is increasingly affected by climate variability, land-use change, and rapid population growth, with the Chókwe floodplain in Mozambique representing a hotspot of socio-economic vulnerability to floods. Study focus: This study applies the
Background: The routine use of sedation and analgesia during post-cardiac arrest care and its association with clinical outcomes remain unclear. This study aimed to describe the use of sedatives and analgesics in post-cardiac arrest care, and evaluate associations with good functional outcome, survival, clinical seizures, and late awakening. Methods: This was a post hoc analysis of the TTM2-trial,
Introduction: The recent Covid-19 pandemic has renewed interest in studying the impact of environmental factors on the airborne transmission of viral infectious diseases. Human rhinovirus is the main cause of acute respiratory infections, primarily driven by young children who have an average of 6 -10 infections annually, while healthy adults typically experience 2–3 infections per year. Although
The Applied Nuclear Physics Group at Lund University has constructed a CANS (Compact Accelerator-driven Neutron Source). The CANS is based around a 3 MV, single-ended, Pelletron accelerator, which is used to impinge a 2.8 MeV deuterium beam into a beryllium target. The anticipated neutron production will be on the order of 1010 n/s in 4π sr, with future upgrades expected to increase neutron produc
AIM: We aimed to study the importance of erbB2 status in early stage postmenopausal breast cancer for patients who participated in a trial of five vs. two years of adjuvant tamoxifen.PATIENTS AND METHODS: We analysed the erbB2 status of the tumours from 577 patients participating in the trial, either by a DNA amplification assay (n = 181) or by measurement of the protein level with flow cytometry
The performance of six custom-built Hygrocopicity-Tandem Differential Mobility Analyser (H-TDMA) systems was investigated in the frame of an international calibration and intercomparison workshop held in Leipzig, February 2006. The goal of the workshop was to harmonise H-TDMA measurements and develop recommendations for atmospheric measurements and their data evaluation. The H-TDMA systems were co
In the native bovine casein micelle the calcium sensitive caseins (alpha(S1)-, alpha(S2)- and beta-casein) sequester amorphous calcium phosphate in nanometer-sized clusters, whereas the calcium-insensitive K-casein limits the growth of the micelle. In this paper, we further investigate the self-association of kappa- and beta-casein, which are two of the key proteins that control the substructure o
Manual cartographic generalization is a simultaneous process. However, most automatic approaches so far have been sequential; generalization operators are applied one at a time in a certain order. This has been the case both for model generalization (generalization of the conceptual model) and graphic generalization. Our research seeks to demonstrate that the graphic part of cartographic generaliz
It is essential to label roads, landmarks, and other important features on maps for mobile applications to help users to understand their location and the environment. This paper aims to examine real-time map labelling methods suitable for the small screen on mobile devices. A slider method with a continuous search space was proposed to sequentially label both line and point features. The method s
This study has evaluated the sampling density for creation of high-resolution digital elevation models (DEMs) for precision agriculture purposes. The relationships between yield and topographical factors were investigated in a study area located in the central Sweden province of Dalarna. The DEM data sampling was carried out with a RTK-GPS system. A dense sampling scheme was employed and data was
The amount of volunteered geographic information (VGI) has increased over the past decade, and several studies have been conducted to evaluate the quality of VGI data. In this study, we evaluate the completeness of the road network in the VGI data set OpenStreetMap (OSM). The evaluation is based on an accurate and efficient network-matching algorithm. The study begins with a comparison of the two
