BACKGROUND: The aim of the study was to investigate the value of percutaneous fine-needle aspiration cytology (FNAC) in the diagnosis and management of liver tumours. METHODS: FNAC followed by histopathological examination was carried out in 216 patients with suspected liver tumours. The final diagnosis was primary liver cancer in 106, colorectal metastases in 51, non-colorectal metastases in 46,

Popular Abstract in Swedish Avhandlingen består av fem fristående uppsatser som utnyttjar tidsserieanalys för studerande av några olika makroekonomiska frågor. I kapitel två, tre och fyra används s.k. vektorautoregressiva (VAR) modeller för att studera privat konsumtionsbeteende i Sverige. Enligt den permanenta inkomst hypotesen väljer individerna sin konsumtion med hänsyn till sin långsiktiga ellAdvances in time series analysis during the last two decades have stimulated research in a number of areas in macroeconomics. This thesis is a compilation of five essays using cointegrated vector autoregressive (VAR) models, unit root tests and regime switching models to investigate the behavior of private consumption, public debt and the real exchange rate. Chapter two explores the empirical evi

Background: Acute pancreatitis (AP) is a common and potentially severe disease. Early identification of severity grade is crucial for the outcome of the patient. For study approaches and comparison of inter-institutional data the AP patients need to be uniformly classified.The aims of this thesis were to investigate the early stratifiation capacity of biomarkers in AP and to assess the morphologic

Population ageing places pressure on pensions and health care services, creating an imperative to extend working lives. Alongside this, there has been increased political emphasis in Europe and elsewhere on the provision of care in the home. Many older people will increasingly be challenged by the responsibilities of caring for the sick, disabled and elderly, and participating in the labor market.

In interstadial deposits, sand interbeds gain limited consideration in comparison with organic sediments, and therefore tend to be underrepresented in paleoenvironmental reconstructions. The Raunis site, central-eastern Latvia, is an example where organic beds have already gained some attention and been used to understand the complex interactions between advance and retreat of the Scandinavian Ice

Indonesien har ratificerat de viktiga internationella mänskliga rättigheter-traktaten som ålägger stater att eliminera diskriminering av kvinnor – CEDAW, ICCPR och ICESCR. Ändå existerar omfattande diskriminering av kvinnor i landet, underblåst särskilt av lokala regleringar som tillkommit genom den starka regionala autonomin. Dessa regleringar, antagna på provins-, region- eller stadsnivå, bryterIndonesia has ratified the crucial international human rights treaties obligating states to eliminate discrimination against women – the CEDAW, the ICCPR and the ICESCR. Yet discrimination against women exists in Indonesia, especially fuelled by local regulations able to arise due to the country’s strong regional autonomy. Enacted either at province, regency or city level, these regulations contra

This paper explores how effective the Danish Greencard opt-out is in impeding the process of Europeanization. It investigates the cases of the Danish Greencard scheme and the German EU Blue Card directive in order to determine if national Danish sovereignty has been preserved through this opt-out. Opt-outs and high-skill migration are some of the most under evaluated topics within the field of Eur

This thesis investigates the relationship between the demographic dividend and institutions. The aim is to make an attempt of attaining further knowledge about the requirements for obtaining a demographic dividend. This is done through the comparison of Asian countries and South American countries. The obtained results confirm the positive effects of an increase in the working-age population relat

Software development for embedded systems has a lot of dependencies on the hardware of the system. To possibly reduce the lead time and ease the development process, an emulated model is investigated. This model is examined in terms of how it fits in the platform transition, daily development and testing processes at Axis. The results indicate that an emulated model is a powerful tool for a softwa

Myoelektrisk kontroll av handprotes Att förlora en hand är en stor förlust och även om allt mer avancerades proteser tillverkas är de fortfarande långt ifrån att prestera lika bra som en riktig hand. För att kunna styra handproteser på ett intuitivt sätt används myoelektrisk kontroll. En metod där man spelar in kroppen muskelsignaler och översätter dem till signaler som kan styra t.ex. en robothaThe goals of this project are to investigate the viability of using the MyoTM armband developed by Thalmic labs as a tool for myoelectric control of a hand prosthesis as well as investigate whether the armbands ability to record its spatial position and orientation can be used to increase the performance of the prosthesis control program. Using the surface electrodes, gyroscopes and accelerometers

Since the Financial and Eurozone crisis that erupted in 2009/2010, Germany has seen the rise of a new populist radical right party; the Alternative für Deutschland (AfD). In the years after its establishment in 2013, this party has experienced many electoral successes and entered not only thirteen federal state parliaments, but also the European Parliament in 2014. This development is atypical for

I vilken utsträckning enskilda ska få hjälp och ledning av myndigheterna i ärenden och mål är en intressant och viktig fråga. Den har betydelse eftersom det kan vara avgörande för enskilda parters möjlighet att tillvarata sin rätt emot det allmänna. En avvägning måste även göras mot det allmännas resurser. Sedan förvaltningsreformens införande på 1970-talet har synen på denna fråga förändrats samtTo what extent the individual should receive help and guidance from authorities in a matter or a case is an interesting and important question. It is significant because it can be important for individuals’ possibilities to exercise their rights. There must also be a balance between guidance and the public resources. Since the administrative law reform was introduced in the 1970s, the perception o

Glaciärer har visat sig vara känsliga för klimatologiska förändringar i sitt närområde och deras känslighet sträcker sig över flera olika tidsskalor. Glaciärerna har därför kommit att användas som indikatorer på både pågående och förhistoriska klimatförändringar. För att glaciärerna ska kunna spegla klimatet så krävs emellertid tillförlitliga mätmetoder av glaciärernas massa. I avsikt att återge gGlaciers integrate variations in climate over several different time scales and are thus used as indicators of both present and past climate change. It is however of importance to be able to correctly measure changes in the glaciers mass over time (the glaciers mass-balance), if one wishes to use the glaciers as climate indicators. The mass-balance of a glacier is a direct result of the glaciers a

A new low pressure fuel system implementation for Scania’s trucks is being investigated. The main challenge consists in exchanging the mechanical pump with electrical pumps. The electrical pumps must then be controlled to supply exactly the demanded amount of fuel at the required pressure. System redundancy allows a lot of degrees of freedom influencing the final performance. This thesis studies t

The main focus of this thesis was to evaluate the possibility of establishing a wastewater treatment model for the main COD removal parts in the water line of Sjölunda Wastewater Treatment Plant (WWTP) located in Malmö, in southern Sweden. The finalised model was used to simulate an increased load of on average 5,000 population equivalents (P.E.) per year due to population growth in Malmö. The aim

The purpose of this Master’s thesis is to find out which measures for reading promotion are used by school libraries and how these can have an effect in terms of increased reading. This is of interest since surveys have shown that Swedish pupils read less and that their reading abilities have decreased. In order to become good at reading one needs to read a lot and this is why promoting reading is
