OBJECTIVES: To test prospectively the diagnostic performance of two logistic regression models for calculation of individual risk of malignancy in adnexal tumors (the 'Tailor model' and the 'Timmerman model'), and to compare them to that of 'pattern recognition' (subjective evaluation of the gray-scale ultrasound image and color Doppler ultrasound examination). DESIGN: Consecutive women with a pel

Libraries of things, non-for-profit physical spaces where people borrow objects they would otherwise buy, have spread over Europe, the U.S., and Canada and have now emerged in Mexico City, where challenges to sustainability such as increased consumption levels and insufficient waste management abound. Collaborative economy initiatives like libraries of things are exposed as more sustainable altern

Ångcentralen på AAK har 4 olika pannor och huvudpannan är en biobränslepannan. Denna panna benämns även som Panna 4 och eldas idag med hushållspellets av klass A1. Vid förbränning så bildas kväveoxider, NOX, som har en negativ effekt på miljön och människor. AAK som idag ligger under villkorsvärdet för utsläpp av kväveoxider enligt krav från Förordning 2013:252 som gäller för stora förbränningsanlThe steam power station at AAK has 4 different boilers and the main boiler is a biofuel boiler. The boiler uses household pellets of type A1. During combustion, nitrogen oxides, NOX, are formed and they have many negative effects on the environment and has direct and indirect effects on human health. Today AAKs NOX emission are lower than the restricted regulation value for nitrogen oxide emission

The study of home has historically been approached by numerous academic disciplines within the social sciences and humanities. However, increased international mobility and forced migration due to conflict in recent years has produced a renewed interest to understand the ways we conceptualize and (re)create home in foreign places. The present research aims to produce a theoretical framework that a

Vårt syfte med uppsatsen är att vidareutveckla förståelsen för mellanchefers inverkan på kunskapsöverföring inom ett företag som nyligen genomgått en förändring inom organisationen. Vi har därefter utvidgat förståelsen för kunskapsöverföringsfältet genom att koppla samman mellanchefens betydelse med tolkning samt begreppen kodning och avkodning. Studien genomförders genom intervjuer med medarbetar

The expression of secondary ornaments is often positively correlated with the bearer's condition. So far no study has reported on consequences of directional selection on male sexual ornaments in birds, i.e. it is unknown to what extent male sexual traits are genetically correlated and whether selection for secondary ornaments affects viability. In this study we estimate phenotypic and genotypic p

The movement and distribution of ecologically important herbivores such as elephants are of great significance to conservation biologist seeking to understand the fundamental triggers that influence their mobility and the extent to which these parameters affect how they utilize their immediate and surrounding resources. The recent advancement in animal tracking technology coupled with the availabi

Population ageing affects most European countries, placing increasing pressure on publicly funded Long Term Care (LTC) systems. Informal care is often seen as a low-cost alternative to formal care services, yet it may induce unwelcome reductions in labour supply. This study presents evidence on the relationship of informal care provision, employment probability, and work hours of mature caregivers

Directive 2003/54/EC of the European Commission set the ground for an integrated and liberalized electricity market in Europe. According to the law of one price the possibility for perfect arbitrage and the absence of trade restrictions lead to homogeneous goods being priced uniformly across countries. The aim of this study is to test whether the law of one price is applicable to the electricity m

Svår, elakartad och längre gången cancer är ett stort problem i förhindrande av spridda tumörceller i kroppen. I detta sjukdomsstadium är oftast en lindrande (palliativ) behandlingsform enda vägen att välja för att hjälpa patienten. För närvarande sker detta genom att patienten får genomlida extern strålbehandling eller cellgiftsbehandling. Radioaktivt märkta och ”målsökande” antikroppar injicerNew radionuclide therapies in humans should be preceded by experimental animal therapies, in order to evaluate the efficacy of the new therapy regime. These experimental studies have to be performed with a reliable and accurate quantification system, with properties that have been evaluated and where possible flaws have been corrected for. The aim of this work was to evaluate the SPECT pinhole col

Although vegetation phenology thresholds have been developed for a wide range of mapping applications, their use for assessing the distribution of natural bamboo and the related carbon stocks is still limited, especially in Southeast Asia. Here, we used Google Earth Engine (GEE) to collect time-series of Landsat 8 Operational Land Imager (OLI) and Sentinel-2 images and employed a phenology-based t

Laser-based fabrication of metal-halide perovskite mini-modules has recently been demonstrated using nanosecond (ns) laser pulses. However, it still suffers from high-resistance contacts due to remaining PbI2 residues at the bottom of the absorber-opening P2 scribe line. Therefore, in this study, we investigate the effect of shorter picosecond (ps) laser pulses, and thus lower heat input, on the c

Introduction TCP-25 gel is intended for use in treatment of wound infection and inflammation. Current local therapies for wounds have limited efficacy to prevent infections and there are no wound treatments available today that target the excessive inflammation that often hampers wound healing in both acute and chronic wounds. There is therefore a high medical need for new therapeutic alternatives

Background: Children with right ventricular outflow tract (RVOT) anomaliestypically undergo surgical repair during their first months of life and thereafter they will need one or more reoperations through their life.Aims: The overall aim was to describe health-related quality of life (HRQoL) forchildren with congenital heart disease (CHD) with a special focus on children withRVOT anomalies and to

Objective: The purpose of this study was to determine, using a top-down genetic analysis, the degree of specificity of the genetic risk factors for individual forms of substance use disorders (SUD). Method: We examined and followed to December 31, 2018, all individuals born in Sweden between 1960 and 1990 (N = 2,772,752) diagnosed with any of the following six SUDs: alcohol use disorder (AUD), dru

Background: The risk of adults with a congenital heart defect (ACHD) developing heart failure, stroke, arrhythmias, and the need for valve replacement is increased compared to healthy peers. Evidence for the use of novel oral anticoagulants (NOAC) in this patient group is still lacking and vitamin K antagonists (VKA) are the primary choice for patients with a mechanical valve. The present aim was
