The objective of this study was to investigate the characteristics of a solid-state detector commonly available at hospitals for parallel use as a real-time personal radiation monitor following radiation emergency situations. A solid-state detector probe with an inherent filtration (R100, RTI Electronics AB, Mölndal, Sweden) was chosen for evaluation. The energy dependence and the linearity in sig

Previous investigations of aqueous based ethyl cellulose (EC) latex dispersions have mainly focused on the commercially available viscosity grade 20 cps. In this study, dispersions of EC with varying viscosity grades (which correspond to molecular weights), ranging from 4 to 100 cps, were produced and characterised. The dispersions showed particle sizes around 200 nm and highly negative ζ-potentia

Regime-based asset allocation has been shown to add value over rebalancing to static weights and, in particular, reduce potential drawdowns by reacting to changes in market conditions. The predominant approach in previous studies has been to specify in advance a static decision rule for changing the allocation based on the state of financial markets or the economy. In this article, model predictiv

Nerve injuries extend from simple nerve compression lesions to complete nerve injuries and severe lacerations of the nerve trunks. A specific problem is brachial plexus injuries where nerve roots can be ruptured, or even avulsed from the spinal cord, by traction. An early and correct diagnosis of a nerve injury is important. A thorough knowledge of the anatomy of the peripheral nerve trunk as well

Summary. Physical activity has been considered as an important factor for bone density and as a factor facilitating prevention of osteoporosis. Bone density has been reported to be reduced in haemophilia. To examine the relation between different aspects of physical activity and bone mineral density (BMD) in patients with severe haemophilia on long-term prophylaxis. The study group consisted of 38

The concentrations of ''free'' chloride and hydroxide ions in extracted pore solution from concrete exposed and submerged in a marine field station were studied by the pore solution expression method. In addition, the corresponding concentrations of total acid soluble chloride in the concrete was analyzed. The relationship between total and free chlorides was analyzed and compared with similar dat

BACKGROUND AND AIMS: Recruitment of leukocytes in the tissue microvasculature is considered to be a rate-limiting step in ischemia-reperfusion (I/R)-induced inflammation. The objective of this study was to examine the role of mast cells in CXC-chemokine- and I/R-provoked leukocyte recruitment in the colon. MATERIALS AND METHODS: Balb/c- and mast-cell-deficient mice were challenged with the CXC che

Popular Abstract in Swedish Samhällets stöd, service och vård till människor med psykiska funktionshinder har under de senaste decennierna genomgått stora förändringar. Det har skett en övergång från slutna till samhällsbaserade öppna vårdformer. De kraftiga nedskärningarna av den sjukhusbaserade psykiatriska vården har emellertid långt ifrån alltid ersatts med ett heltäckande och fungerande vård-All clients admitted to ten pilot case management services for individuals with severe mental illness during 1995 and up to 1996-09-30 were invited to participate in the present study. A total of 176 clients were included. The clients were in all services assessed at admission and at an 18 months follow-up with regard to needs of care, psychosocial functioning. Use of health care and social servic

The purpose of this study was to develop a computer-based method for automatic detection and localization of coronary artery disease (CAD) in myocardial bull's-eye scintigrams. Methods: A population of 135 patients who had undergone both myocardial 99mTc-sestamibi rest-stress scintigraphy and coronary angiography within 3 mo was studied. Different image data reduction methods, including pixel aver

The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. The two parts are linked together with a glucoside bond. In nature, the building and breakage of a glu

Body fatness has been associated with increased risk of a number of hormone-dependent cancers. Recent studies suggest that body mass index (BMI) may be related to meningiomas, which are more common in women than men, and for which estrogens are believed to play a role. Using data from a large European propective cohort, 203 incident cases of meningioma and 340 cases of glioma were included in the

Androgenic hormones occur naturally in bird egg yolk and are known to enhance growth in canary and gull chicks. Gil et al. (1999, Science, 286, 126-128) have recently proposed that female allocation of androgens to eggs represents a form of costly maternal investment. This hypothesis predicts that females of high quality or high reproductive potential should invest more yolk androgens in their egg

Background: Domestic violence is a global health problem as well as a violation against human rights. The aim of this study was to explore prevalence and incidence of domestic violence during pregnancy and 1 to 1.5 years postpartum as well as to explore the history of violence among new mothers in the southwestern region of Sweden. In addition, the aim was to explore the association between domest

I en bransch som i allt större utsträckning präglas av hållbarhet och miljö, blir det allt viktigare att hitta sätt att återvinna och återanvända snarare än att nyproducera. Ett exempel på detta är när det kommer till de obundna lagren, bär- och förstärkningslager i vägöverbyggnaden. Till dessa används traditionellt bergkross och naturgrus, som bryts från bergtäkter. Dessa material är inte oändligIn an industry that is increasingly affected by sustainability and environmental matters, it is becoming more and more important to find ways to recycle and reuse materials rather than producing new materials. An example of this is when it comes to unbound pavement materials, such as the base and subbase layers. For these layers, mineral aggregate and natural gravel is traditionally used, which ar

The aim of this study was to explore social workers’ experiences with the assessment tool UngDOK at Maria clinics in Skane. The past 30 years has seen a rise in popularity of evidence based practices and increased requirements for scientific evidence of the effects of various treatments. Several manual based evaluation and assessment instruments have been implemented in the field of social work in

Sveriges vattenledningsnät kräver kontinuerliga och stora in- vesteringar och måste underhållas på ett effektivt sätt; syftet med den här studien var därför att utröna vilka ledningsattribut som är viktigast för att i en ANN-modell identifiera ledningar med hög risk för läckage. Detta gjordes genom att först använda attri- buturvalsmetoderna ReliefF och Recursive Feature Elimination (RFE) tillsammanSweden’s water pipe network demands continuous and large investments and must be maintained in an effective way; the aim with this study was therefore to investigate which pipe features are most important to identify pipes with a high risk of leakage in an ANN-model. This was done by first utilizing the feature selection methods ReliefF and Recursive Feature Elimination (RFE) with Random Forest Clas

Framställningen syftar till att belysa den svenska vårdnadslagslagstiftningen avseende bestämmanderätten vid gemensam vårdnad samt konsekvenserna av vårdnadshavares oförmåga att samarbeta i frågor som rör barns rätt till vård. Enligt svensk familjerätt är det bästa för barnet att stå under föräldrarnas gemensamma vårdnad samt att föräldrarna tar gemensamma beslut i alla frågor som rör barnet. NämnThe aim of this thesis is to analyse the current legislation regarding the right of decision under joint legal custody and the absence of legal rules in this area. The thesis furthermore analyses the consequences of the legal requirement of consensus between the parents for all decisions regarding the child, as well as the consequence of the parents inability to cooperate when it comes to the chil

Populärvetenskaplig sammanfattning En förändring i det rådande klimatet med en temperaturhöjning på grund av en ökad atmosfärisk CO₂-koncentration kan komma att ha en påverkan på skogar över hela jordgloben. Trädarter som är anpassade till ett visst klimat kan komma att spridas norrut då klimatet kan vara mer passande i framtiden. Detta medför risken att lövträd från central Europa kan konkurrera A climate change will affect the forests around the globe; there may be competitions for available resources that are needed for growth and dispersal. Europe is supposed to be more sensitive and may experience a greater influence than many other regions. As an additional effect of climate change extreme weather events will be more frequent e.g. drought and extreme precipitation that will cause flo

Populärvetenskaplig sammanfattning Klimatet har sedan den industriella revolutionen förändrats globalt och kommer att förändras ytterligare i framtiden, på grund av människans utsläpp av växthusgaser. Enligt vetenskapliga beräkningar kommer klimatet att bli varmare, vilket i sin tur leder till att den globala havsnivån kommer att stiga. Hela världen kommer drabbas, även Sverige. Därför krävs det aSince the industrial revolution the global climate has changed and will change further in the future. According to scientific estimations the climate will get warmer, which will rise the global sea level. The whole world will be affected, also Sweden. It is therefore necessary to adapt society for the estimated climate change to reduce negative effects. In May 2012 a change in the Swedish law of

In the last couple of years it has become more and more common to use control theory in computing systems, for instance operating systems, web servers and databases. The reason for this is to make these systems more robust and stable. This is of interest because we today are more dependent on computing systems in our everyday life, and therefore put higher demands on them. A lot of focus has been
