Background. The objectives of this report are to evaluate changes in the preterm birth rate in Sweden 1973-2001. Furthermore, describe the proportion of spontaneous and indicated preterm births and assess risk factors for the subgroups of preterm birth during the period from 1991 to 2001. Methods. A population-based register study of all births occurring in Sweden from 1973 to 2001 registered in t
Selective catalytic reduction of NOx (SCR) has been recognised as an effective post-combustion method for reducing nitrogen oxides from stationary sources. The cost of replacing the catalyst is a major part of the maintenance of the SCR system, hence it is desirable to advance methods to prolong the catalyst life. The objectives of this thesis were to investigate the extent and the mechanism of de
Early peat surveys demonstrated the potential to detect Holocene climatic changes in southern Sweden through analysis of the degree of decomposition of Sphagnum peat and motivated systematic collection of peat-strati graphic information during subsequent geological mappings in central and northern Sweden. The resulting (published and unpublished) data was compiled and reanalysed, taking into accou
Fourier transform infrared (FTIR) and extended X-ray absorption fine structure (EXAPS) spectroscopic measurements were performed on Pb(II)ethylenediaminetetraacetic (EDTA) adsorbed on goethite as a function of pH (4-6), Pb(II)EDTA concentration (0.11-72 mu M), and ionic strength (16 mu M-0.5 M). FTIR measurements show no evidence for carboxylate-Fe(III) bonding or protonation of EDTA at Pb:EDTA =
We tested domestic cats in the cylinder task, and found that they perform better ifthe cylinder is larger. We also found that their highest performance parallels that ofgreat apes and corvids, which are known as the best performing animals on this task.The cylinder task is used to test animals’ motor self-regulation. Recently a large-scalestudy tested 36 species on the task and found that absolute
Background: A common complaint by people with tinnitus is that they experience that the tinnitus causes attention and concentration problems. Previous studies have examined how tinnitus influences cognitive performance on short and intensive cognitive tasks but without proper control of hearing status. Purpose: To examine the impact tinnitus and high-frequency hearing thresholds have on reading co
Increasing evidence supports the benefit of identifying BRCA1 and BRCA2 germline mutations in early breast cancer. Selection of patients for genetic testing is based on defined criteria taking individual and family history related factors into account. It is important to make a distinction between efficacy and effectiveness of BRCA testing criteria. Efficacy can be defined as the performance under
Hospitalised patients are faced with a brute reorientation of their normal spatial needs andpreferences and forced to adjust spatially to a new environment. Patients start to re-arrangetheir own situation according to personal needs and the site-specific circumstances. It is are-arrangement that includes furniture, private objects and spatial positioning, but also theadjustment to the presence and
BACKGROUND: Genetic association studies have reported single-nucleotide polymorphisms (SNPs) at chromosome 19q13.3 to be associated with prostate cancer (PCa) risk. Recently, the rs61752561 SNP (Asp84Asn substitution) in exon 3 of the kallikrein-related peptidase 3 (KLK3) gene encoding prostate-specific antigen (PSA) was reported to be strongly associated with PCa risk (P 2.3 108). However, the bi
BACKGROUND: Liver resection provides the best chance for cure in colorectal cancer (CRC) liver metastases. A variety of factors that might influence survival and recurrence have been identified. Predictive models can help in risk stratification, to determine multidisciplinary treatment and follow-up for individual patients. AIMS: To systematically review available prognostic models described for o
This longitudinal study used a multi-disciplinary approach and examined the relationship between psychosocial and health characteristics and the pattern of informal and formal support for non-institutionalized very old people. The data were derived from a single cohort of 80-year-old people living in Lund, Sweden who were followed over a 3-year period. In order to account for potential sample bias
Active surveillance of invasive group A streptococcal (GAS) infections was conducted in Denmark during 2003 and 2004 as a part of the Strep-EURO initiative. The main objective was to improve understanding of the epidemiology of invasive GAS disease in Denmark. During the 2 years, 278 cases were reported, corresponding to a mean annual incidence of 2.6 cases per 100,000 inhabitants. The vast majori
Background: Soils contain the largest stock of organic carbon (C) in terrestrial ecosystems and changes in soil C stocks may significantly affect atmospheric CO2. A significant part of soil C is present in cultivated soils that occupy about 35 % of the global land surface. Agricultural intensification has led to practices that may decrease soil organic carbon (SOC), and agricultural management has
We analyze the Ce3+-Pr3+:Y2SiO5 emission spectra obtained under selective excitation of the two Ce3+ sites in Y2SiO5 and we show clear evidence of direct energy transfer from Ce3+ to Pr3+. Energy transfer microparameters were calculated from the experimental spectral overlap between the Ce3+ emission and the Pr3+ and Eu3+ absorptions from which, the transfer mechanisms Ce3+-> Pr3+ are concluded to
Atmospheric N deposition is known to severely impact forest ecosystem functioning by influencing soil biogeochemistry and nutrient balance, and consequently tree growth and overall forest health and biodiversity. Moreover, because climate greatly influences soil processes, climate change and atmospheric N deposition must both be taken into account when analysing the evolution of forest ecosystem s
1. Human activities have promoted the spread of species worldwide. Several crayfish species have been introduced into new areas, posing a threat to native crayfish and other biota. Invader success may depend on the ability to utilise a wide variety of habitats and resources. Successful invaders are generally expected to have broader niches and to be more plastic than non-invasive species. 2. Using
As a complementary product to the Tetra Brik Aseptic packaging system, Tetra Pak is about to introduce a new, value added, aseptic packaging system called SCAP. The SCAP packages consists of a lower part made of carton and an upper part made of plastic, similar to a PET-bottle, resulting in a bottle shaped package. The purpose of this thesis is to design a logistical- and material-handling system
In the past few decades the ways of addressing past atrocities in states on the verge of transition from abusive regimes to human rights abiding democracies have developed into an area of international law commonly known as 'Transitional Justice'. The focus lies on facilitating the transition through different measures with the purpose of addressing the past and seeking reparation for the
Barn har ett särskilt skyddsvärde och när de utsätts för brottsliga gärningar har de, precis som vuxna, ett behov av upprättelse men också en rätt att få uppleva att rättvisa skipas för att få ett avslut på brottsupplevelsen. I Sverige tillmäts den rättsliga hanteringen av unga brottsoffer stor betydelse för utgången i målet och det ställs således höga krav på att barnets särskilda behov tas i beaChildren have a specific need for protection and especially when subject to criminal acts. Similar to adults, children also have a need for redress and a right to experience that justice will be served in order to find a closure to the process associated with crime victimization. In Sweden, the legal treatment of young victims of crime is of great importance for criminal judgement and thus high de
Motivation and Objective: This study investigates how analysts generate from data using business intelligence tools. The motivation for study at the premise that organizations are finding it very challenging to gener-ate insights from a vast amount of structured, semi-structured and unstructured data. The ini-tial problem background indicate that this may be because organizations are silo driven,
