Objective To determine whether intravenous contrast ultrasound examination is superior to gray-scale or power Doppler ultrasound for discrimination between benign and malignant adnexal masses with complex ultrasound morphology. Methods In an international multicenter study, 134 patients with an ovarian mass with solid components or a multilocular cyst with more than 10 cyst locules, underwent a st

Background: Hitherto, risk prediction models for preoperative ultrasound-based diagnosis of ovarian tumors were dichotomous (benign versus malignant). We develop and validate polytomous models (models that predict more than two events) to diagnose ovarian tumors as benign, borderline, primary invasive or metastatic invasive. The main focus is on how different types of models perform and compare. M

The objective of this Master’s Thesis, entitled “How to increase tolerance regarding co-planarity when using larger shield cans”, is to find solutions for how to solder larger shield cans to the printed wired board (PWB) without losing shielding effectiveness. Advantages with larger shield cans, i.e. combining several smaller shield cans into one large with internal walls, are saved board space, e

Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. A house with dynamic insulation was continuously measured for approximately a year and a half. The performance of the dyna

Objective: In this study, we propose a novel framework that utilizes deep learning and attention mechanisms to predict the radiographic progression of patellofemoral osteoarthritis (PFOA) over a period of seven years. Design: This study included subjects (1832 subjects, 3276 knees) from the baseline of the Multicenter Osteoarthritis Study (MOST). Patellofemoral joint regions-of interest were ident

Ecological intensification has been embraced with great interest by the academic sector but is still rarely taken up by farmers because monitoring the state of different ecological functions is not straightforward. Modelling tools can represent a more accessible alternative of measuring ecological functions, which could help promote their use amongst farmers and other decision-makers. In the case

Background: The aim of this study was to provide normative data of bone mineral density (BMD; g/cm(2)) of the forearm and the calcaneus, evaluated by peripheral dual X ray absorbtiometry (DXA), in children aged 6 to 7 years of age and to evaluate the association with anthropometrics and sex. Materials and methods: 368 boys and 326 girls with a mean age of 6.7 +/- 0.4 years participated. BMD was me

Syftet med uppsatsen är att genom en rättsdogmatisk metod och ett kritiskt perspektiv granska huruvida innehållet i termen barnets bästa förhåller sig till brottsofferbegreppet i svensk rätt. Uppsatsen behandlar frågan om en inkorporering av barnkonventionen är motiverad med hänsyn till barnets rätt att komma till tals i situationer där barn bevittnar våld mot närstående. Frågan om barn som bevitt

Uppsatsen behandlar temat tvångsomhändertagande av unga på grund av deras beteende utifrån ett rättsutvecklingsperspektiv. Uppsatsen har två syften. Det första syftet är att undersöka huvuddragen i den historiska utvecklingen av lagstiftningen om tvångsomhändertagande av unga på grund av deras beteende. Det andra syftet är att diskutera hur lagstiftningen kring dessa fall, som idag kallas beteendeThe thesis discusses compulsory care of young people due to their behaviour from a law development perspective. The thesis has two purposes. The first purpose is to investigate the main features of the historical development of the legislation about compulsory care of young people due to their behaviour. The second purpose is to the discuss how the legislation of these cases, which today are calle

Purpose: (1) Determine whether there is an inconsistency between the disclosed WACC and the WACC applied in CGU’s for internal impairment tests, with respect to IAS 36. (2) Determine to what extent companies apply a company-wide WACC internally in all CGU’s, when conducting impairment tests in accordance with IAS 36. (3) Describe and analyse the incentives for companies to apply a company-wide WAC

In Ecuador, more than 85% of electricity production relies on hydropower and consequently the supply of electricity relies on water availability. During the dry season (October-March) hydropower capacity could diminish up to one-third of its installed capacity or more under a severe drought causing a substantial augmentation of thermoelectric power output to offset the lack of hydropower to cover

Den gängrelaterade brottsligheten har ökat kraftigt i Sverige. Regeringen har av denna anledning infört visitationszoner som ett verktyg för att bekämpa detta. Inom zonen ska polisen få utökade befogenheter att söka efter vapen och andra farliga föremål på människor och fordon utan konkret brottsmiss-tanke. Visitationszoner är ett komplext problem där många starka intressen står mot varandra. UppsGang-related crime has increased significaly in Sweden. For this reason, the government has introduced visitation zones as a tool to combat this issue. Within this zone, the police will be given extended authority to search for weapons and other dangerous objects on people and vehicles without concrete suspicion of crime. Visitation zones pose a complex issue where many strong interests stand agai

Blekinge Offshore AB är ett företag som planerar att anlägga en vindkraftspark ute till havs i Hanöbukten. Om den fullskaliga parken byggs kommer 7-8 TWh elektricitet produceras årligen. Från landanslutningen på Stärnö i Karlshamns Kommun sträcker sig kraftledningar cirka 21 kilometer upp till en knutpunkt i Hemsjö, Olofströms Kommun. För att den fullskaliga parken ska kunna byggas måste dock den Blekinge Offshore AB is a company with intentions of building an offshore wind farm in the bay of Hanö, in southern Sweden. If the full-scale park is constructed a total of 7-8 TWh of electricity will be produced annually. From the land connection in Stärnö, municipality of Karlshamn, current power lines stretch 21 kilometers up to a junction in Hemsjö, municipality of Olofström. If the full-scale

A next-generation drinking water purification device has been developed which uses UV-LEDs to create high intensity UV light to inactive the bacteria present in the water that flows through the device tube chamber. The capacity of the different setups of the devices to perform water purification was examined by experimental testing. This report investigates using a new flow cytometry approach comp

Energifattigdom definieras som ett tillstånd där ett hushåll inte kan tillgå tillräckligt med energi för att underhålla en rimlig levnadsstandard. Problemet uppstår i en kombination av låg inkomst, energikrävande bostäder och höga energikostnader. Mellan 50 och 125 miljoner invånare i Europa uppskattas vara drabbade. Utanförskap, hälsoproblem och i värsta fall att människor dör i förtid är exempelEnergy poverty (EP) is, in the scholarly literature, defined as a household’s inability to obtain a socially and materially acceptable level of energy services in the home. This is a widespread issue affecting an estimated 50 to 125 million people in Europe. Measures to tackle EP have yielded successes using proactive area-based schemes that target groups of households in the same geographic are

Cartels are by nature secretive and thereby hard to find. As a way to stop these hard-core cartels an American system emerged which since has been exported worldwide - a leniency pro-gramme. The affected parties are given an opportunity to inform the authorities and the com-pany who does so is in return released from any potential charges, provided that they follow the authorities guidelines durin

När föräldrar inte själva kan komma överens i frågor om vårdnaden om, boendet för eller umgänget med sitt barn, kan frågorna tas upp hos socialtjänsten eller i domstol. När beslut om barn ska fattas, ska barnets bästa vara den slutligt bestämmande faktorn, en aspekt i bedömningen om barnets bästa är barnets behov av en nära och god kontakt med båda föräldrarna.
