Diagnostic reference levels are the main and the most effective tools of optimization of the radiation protection of patients from medical exposure. Diagnostic reference levels should be established based on theresults of dedicated dose surveys, allowing evaluating typical patient dose distributions in a selected dose quantity for the selected X-ray examinations. The aim of the current study was t
An approach to reduce CO2 emissions while simultaneously keeping the soot emissions down from compression ignition (CI) engines is to blend in short chained oxygenates into the fuel. In this work, two oxygenated fuel blends consisting of diesel, gasoline and ethanol (EtOH) in the ratio of 68:17:15 and 58:14:30 have been utilized and studied in a single cylinder light duty (LD) CI engine in terms o
Functional nuclear medicine imaging with single-photon emission CT (SPECT) in combination with anatomical CT has been commercially available since the beginning of this century. The combination of the two modalities has improved both the sensitivity and specificity of many clinical applications and CT in conjunction with SPECT that allows for spatial overlay of the SPECT data on good anatomy image
GALAH is a large-scale magnitude-limited southern stellar spectroscopic survey. Its second data release (GALAH DR2) provides values of stellar parameters and abundances of 23 elements for 342 682 stars (Buder et al.). Here we add a description of the public release of radial velocities with a typical accuracy of 0.1 km s -1
This study was undertaken to evaluate the role of internalization in the action of the peptide autacoid bradykinin (BK). At 4°C [3H]BK binds to an apparently single class of B2 kinin receptors on DDT1 MF-2 smooth muscle cells (C. M. Munoz, S. Cotecchia, and L. M. F. Leeb-Lundberg, manuscript submitted). At this temperature the [3H]BK binding was confined exclusively to the cell surface. On the oth
Modelling is an alternative solution to reduce the cost of water quality monitoring. Commonly, concentration of pollutants is estimated based on limited sampling information. Concentration of ions in rivers can be estimated using modelling strategies that involve statistics and artificial intelligence as well as the understanding of physical processes. Therefore, the performance of feedforward neu
Objective: Patient-provider relationships with primary care and need for hospitalisations are related within the complex networks comprising healthcare. Our objective was to analyse mean days hospitalised, using registration status (active or passive listing) with a provider and number of consultations as proxies of patient-provider relationships with primary care, adjusting for morbidity burden,
Although conventional computer technology made a huge leap forward in the past decade, a vast number of computational problems remain inaccessible due to their inherently complex nature. One solution to deal with this computational complexity is to highly parallelize computations and to explore new technologies beyond semiconductor computers. Here, we report on initial results leading to a device
Sewage ponds with exposed sludge are known to be excellent feeding sites for waders during migration. They still exist in parts of the world but are disappearing in pace with introduction of modern methods which do not involve open exposure of the sludge. Here I report a five-year study from a Swedish plant with open sludge ponds in the 1950s when many similar ones were still active. I counted the
Popular Abstract in Swedish I Män, våld och moralarbete uppmärksammas hur män, som frivilligt sökt sig till verksamheter där det erbjuds behandling för våld i nära relationer, rapporterar om sina erfarenheter. Rapporteringarna består dels av svar på frågeformulär, dels genom deltagande i samtalsintervjuer. Författaren analyserar hur männen förklarar sina handlingar och gestaltar återberättade erfMen, violence and moral work- Reports from help-seeking men at treatment centers working with violence in close relationships Men’s violence against women is an extensive social problem. In the 1970s, a new kind of centers were established in the US and UK, focusing on treating men who had been violent against their wives or girlfriends, the aim which is to end the men’s violent behavior. In the
This doctoral dissertation is an overview of the recently arisen Sango language spoken in the Central African Republic. The overview contains a sociolinguistic and linguistic dimension with a lexical-semantic focus. The study is set within a multidisciplinary framework including a functional-typological perspective, language change induced by contact, and language planning. The study shows that th
Fuel economy and emissions are the two central parameters in heavy duty engines; most of the existing heavy duty engines are run with diesel. The overall efficiency of diesel engines is good however they suffer from high levels of emissions mainly NOX and soot. Using alternative fuels like Natural-Gas has shown to be a good way to reduce emissions level. Diesel engines can be easily converted to N
The importance of rare earth elements in modern technological industry grows, and as a result the interest for developing separation processes increases. This work is a part of developing chromatography as a rare earth element processing method. Process optimization is an important step in process development, and there are several competing objectives that need to be considered in a chromatograph
Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source produced through fermentation of sugars. However, in order to achieve high sugar and ethanol yields, the lignocellulosic material must be pretreated before the enzymatic hydrolysis and fermentation. Dilute acid pretreatment, using SO2, is one of the most promising methods of pretreatment for softwood
The extent of behavioral recovery following neural transplantation in part depends on the amount of surviving graft tissue. The main objective of this thesis was to study parameters affecting the survival of embryonic striatal and mesencephalic neurons in experimental models of Huntington's and Parkinson's disease. Firstly, we studied the survival and maturation of embryonic striatal neurons that
