BACKGROUND: Optimal treatment of soft-tissue sarcoma requires multidisciplinary management at a sarcoma center. However, these rare tumors are often misinterpreted as benign and many are inadequately treated outside a sarcoma center, with an increased risk of local recurrence that often requires further extensive surgical treatment. To improve referral and centralization of soft-tissue sarcoma man
Popular Abstract in Swedish Urinvägsinfektioner (UVI) är en av människans vanligaste bakteriella infektioner och drabbar både kvinnor och män. Kvinnor drabbas av UVI under hela sitt vuxna liv, medan UVI incidensen hos män ökar efter 40 – 50 års ålder pga. ökande problematik i urinvägarna med prostataförstoring, m.m. UVI orsakas av ett flertal olika bakteriearter, men tarmbakterien Escherichia coliUrinary tract infections (UTI) are among the most common human infections, and febrile UTI with bacteremia the most severe form. The relation between bacteria and host decides disease severity. The dominating uropathogen is Escherichia coli (E. coli). P fimbriae are the virulence factor of E. coli most clearly associated to severe disease. P fimbriated E. coli predominated in bacteremic febrile UT
The overall aim of this work is to study and interpret how social relations were expressed, shaped, and changed in the Late Middle Neolithic. The empirical foundation is a study of settlement in the Malmö area, south-west Skåne, Sweden. Other parts of southernmost Sweden (and eastern Denmark) are also concerned. Sites are discussed and given an overall interpretation as regards chronological and c
Popular Abstract in Swedish Energibalansen vid jordytan är av avgörande betydelse för Jordens alla ekosystem men när det gäller Arktiska och sub-Arktiska ekosystem är kunskapen bristfällig. I dynamiska system som klimatsystemet, påverkas utbytet av energi, vatten och växthusgaser av små förändringar i ekosystemen. Syftet med denna avhandling är därför att skapa ökad kunskap och en tydligare bild aThe surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. Therefore, this thesis aims to draw a conclusive picture of the surf
BACKGROUND: Healthcare today is a complex system with increasing needs of specific knowledge of evaluation of research and implementation into clinical practice. A critical issue is that we all apply evidence-based practice (EBP) with standardised methods and continuing and systematic improvements. EBP includes both scientific and critical assessed experience-based knowledge. For the individual,
In analyses of affordances and opportunities in different neighbourhoods it is found that access to public buildings and a well-functioning public space are of outmost importance. This is found to be especially important in neighbourhoods having a population with fewer resources, areas often discussed in terms as ‘deprived’ or ‘excluded’, concepts that alludes to the phenomenon of segregation. Pre
Galaxies with high redshift (z) are galaxies in the early universe, and they differ from local ones. They often show more irregular morphologies and significantly different kinematic properties, as turbulent motion dominates. These early galaxies have higher gas velocity dispersion (σ) and lower rotation-to-dispersion (vrot/σ) values. Recent findings from both the JWST and the Atacama Large Millim
Prisutvecklingen på den svenska bostadsmarknaden har under de senaste åren varit positiv. Lågt bostadsbyggandet i förhållande till befolkningsökningen anses vara en bidragande orsak till den positiva prisutvecklingen. Ett sätt att mäta attraktiviteten på den lokala bostadsmarknaden är Tobins Q. På småhusmarknaden definieras Tobins Q vanligtvis som kvoten mellan ett småhus marknadsvärde och dess iOne way to measure the attractiveness of a local housing market is Tobin’s Q. On the market for single-family housing property, Tobin’s Q is usually defined as the ratio between the market value of the property and its investment cost. This means that the quota can serve as an indicator on whether it is profitable to build a new house or not. The theory states that Tobin’s Q above 1,0 indicates th
Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. The North Sea is an important fishing ground, and any changes in phytoplankton bloom patterns can have a significant impact on the region'
The details of galaxy formation are still an unsolved problem in astrophysics. Even though significant progress has been made in simulations and observations, it remains an unsolved issue to describe the complexity it yields. One of the reasons for this is the vast dynamical range in space and time. The smallest scales, where star formation occurs, are connected to the larger scale structure of th
This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton. This work initiates wi
I och med elektrifieringen av energisektorn ställs höga krav på ökad inhemsk produktion av elektricitet i Sverige. På grund av den nuvarande fördelningen, där en stor del av produktionen sker i norra Sverige medan konsumtionen är koncentrerad till södra delarna av landet, är behovet extra stort i elområde 4 (SE4). Ett län som möter extra stora utmaningar är Skåne där självförsörjningsgraden för elThe current electrification of the energy sector puts high demands on increasing domestic electricity production in Sweden. This issue is enhanced by the current regional imbalance between supply and demand, while a major share of electricity generation is located in northern Sweden, consumption is concentrated in the south. Consequently, the need for new production is particularly great in electr
Context. Until now, heavy interstellar extinction has meant that only a few studies of chemical abundances have been possible in the inner Galactic bulge. However, it is crucial to learn more about this structure in order to better understand the formation and evolution of the centre of the Galaxy and galaxies in general. Aims. In this paper, we aim to derive high-precision α-element abundances us
This thesis comprises three papers studying several mathematical models related to geometric Markov processes and random processes with reinforcements. The main goal of these works is to investigate the dynamics as well as the limiting behaviour of the models as time goes to infinity, the existence of invariant measures and limiting distributions, the speed of convergence and other interesting rel
Accountability to stakeholders has always been pivotal in supporting nonprofit organizations in legitimizing their existence within local communities and building public trust. The development of Web-based accountability tools has offered growing possibilities to communicate and engage in dialogue with stakeholders. However, nonprofit organizations are not yet fully exploiting the potential of the
A series of premixed turbulent methane/air jet flames in the thin reaction zone (TRZ) and distributed reaction zone (DRZ) regimes were studied using simultaneous three-scalar high-resolution imaging measurements, including HCO/OH/CH2O, CH/OH/CH2O, T/OH/CH2O and T/CH/OH/. These scalar fields offer a possibility of revisiting the structures of turbulent premixed flames in different combustion regime
Background: Although transposition of the great arteries (TGA) accounts for less than 5% of congenital heart disease, the clinical course is often dramatic with need for early diagnosis and careful preoperative care as well as advanced surgical correction and postoperative support. Since 1993, Lund is one of the two tertiary referral centers for pediatric cardiac surgery in Sweden, with nearly 400
It would appear that all possible types of source material concerning pre-colonial and colonial Indian history had been found and analyzed only to be reanalyzed repeatedly, resulting in a number of macro-level studies. However, micro-level studies have been very rare. This may be so because many a historian of India believed that sources necessary for such studies did not exist as there was no tra
European populations of the white-tailed eagle Haliaeetus albicilla suffered a drastic decline during the 20th century. In many countries, only a few dozen breeding pairs survived or the species disappeared completely. By today, the populations have recovered, naturally or through restocking (e.g. in Scotland or the Czech Republic). In the Carpathian Basin, which is now a stronghold in southern Eu
Using microdialysis, extracellular noradrenaline (NA) levels in the rat cerebral cortex were studied under isoflurane/N2O anaesthesia before, during and for 6 hours following 10 min of forebrain ischemia in a 2-vessel occlusion model. A microdialysis probe was introduced into the parietal cortex and dorsal hippocampus in anaesthetized rats and continuously perfused with Krebs-Ringerbicarbonate buf
