Abstract Intro A systematic review (SR) attempts to find, assess and summarize all the empirical evidence to answer a specific research question. We aim to explore to what extent reviews are included in doctoral theses from all universities with a medical faculty in Sweden, and to describe the type, topic and assess the methodological quality of the reviews. Methods Duplicate assessors independent

Aim: This paper describes the quality assurance (QA) work performed in the Swedish multicenter ARTSCAN (Accelerated RadioTherapy of Squamous cell CArcinomas in the head and Neck) trial to guarantee high quality in a multicenter study which involved modern radiotherapy such as 3DCRT or IMRT. Materials and methods: The study was closed in June 2006 with 750 randomised patients. Radiation therapy-rel

Whilst many studies have been performed to investigate the spectral induced polarization (SIP) response of Non-aqueous Phase Liquid (NAPL) contaminated soil samples there are still many uncertainties in the interpretation of the data. A key issue is that altered pore space geometries due to the presence of a NAPL phase will change the measured IP spectra. However, without any information on the NA

The ruptured anterior cruciate ligament (ACL) leads to immediate symptoms that severely affect the individual and receives great attention among the scientific community, yet there is still no consensus on the optional form of treatment. An ACL injury is also a well known high risk factor for the development of knee osteoarthritis (OA) some decades later. Knee OA development after an ACL injury is

Popular Abstract in Swedish Nanoteknologi handlar om att på ett kontrollerat sätt utnyttja strukturer med minst en dimension i nanometerområdet (i storleksordningen 1 till 100 miljondels millimeter). Nanostrukturer har använts under lång tid och redan under medeltiden användes guldpartiklar av varierande storlek för att tillverka infärgade glas. Idag använder vi nanoteknologi dagligdags, t.ex. i vThis dissertation deals with the geometric and electronic structure of surfaces on III–V semiconductor nanowires (NWs). NWs made of InAs, GaAs, and InP have been studied using scanning tunneling microscopy/spectroscopy (STM/S), low energy electron microscopy (LEEM), photoemission electron microscopy (PEEM), and x-ray photoelectron spectroscopy (XPS). All of the mentioned techniques have been devel

Nasal decolonisation has a proven effect on the prevention of severe Staphylococcus aureus infections and in the control of methicillin resistant S. aureus (MRSA). However, rising rates of resistance to antibiotics highlights the need for new substances for nasal decolonisation. LTX-109 is a broad spectrum, fast-acting bactericidal antimicrobial drug for topical treatment, which causes membrane di

Under 1800-talet tilltog de antikatolska stämningarna i Europa. Antikatolicismen hämtade sin näring från katolska kyrkans fördömande av såväl protestantismen som den moderna utvecklingen i riktning mot ett sekulärt samhälle. I flera länder utmynnade dessa motsättningar i veritabla sammandrabbningar mellan katolska kyrkan och den av liberala krafter dominerande statsmakten. Man talade om ”kulturkam

Popular Abstract in Swedish I denna avhandling har jag undersökt hur man kan utöka det dynamiska omfånget utan att öka noggrannheten i en analog-till-digital omvandlare med en flyttalsliknande lösning. Den valda lösningen går ut på att man förstärker en analog insignal med flera oberoende analoga förstärkare med skilda förstärkningar. Sedan väljs den förstärkare som ger den starkaste utsignalen sTo deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolut

Popular Abstract in Swedish Denna avhandling utvecklar nya tekniker för analys av kointegrationssamband i paneldata. Det första kapitlet är en introduktion medan de resterande sex innehåller avhandlingens huvudsakliga bidrag. Det andra kapitlet behandlar estimering av kointegrationssamband när regressorerna är endogena, vilket medför att minsta kvadratmetoden inte längre är väntevärdesriktig om dThis thesis develops new techniques for analyzing cointegrated relationships in panel data. The first chapter is introductory while the remaining six contain the main contributions. The second chapter is concerned with the estimation of a cointegrated panel relation with endogenous regressors, in which case the least squares estimator is biased unless it is conditioned on the lags and leads of th

This work is the first comprehensive description of Makalero, a language spoken by approximately 6,500 speakers in the Iliomar subdistrict, in the south-east of the Republic of East Timor. While previous sources considered it to be a dialect of the larger language Makasae, the present study, which is based on primary data gathered by the author during fieldwork in East Timor, notes sufficient gram

Popular Abstract in Swedish Övervikt är ett av vår tids största hälsoproblem, kanske till och med det största. Det finns de som menar att redan idag utgör övervikt globalt sett en viktigare orsak till sjukdom än undernäring och infektionssjukdomar. Framtidsscenariot beskrivs som alarmerande. Folk kommer att i en tidigare aldrig skådad omfattning insjukna i överviktens följdsjukdomar. Medierna harThe prevalence of overweight and obesity is rising each year not only on a national but also on a global level. The future scenario is troublesome. The media are among the most important social institutions in influencing people’s knowledge, perceptions and actions. The media provide citizens with health messages and contribute thereby to their health development. This dissertation deals with two

Popular Abstract in Swedish Upprinnelsen till detta forskningsprojekt ligger i människans önskan att kommunicera. Elektronisk komminikation startade med telegrafen i början av 1800-talet och mot slutet av samma sekel uppfanns telefonen. Till en början var telefonnätet helt passivt, men i samband med upptäckten av elektronröret kopplades förstärkare in i nätet för att lösa problematiken med dämpninThis doctoral dissertation presents a study of linear radio transmitters based on the combined analog locked loop universal modulator (CALLUM) approach. Linear architectures such as CALLUM are very attractive for power-efficient operations, since they have no fundamental limitations prohibiting a 100% efficiency for all envelope levels, without sacrificing the potential of a linear transmission. T

In parallel with an unprecedented progress in vascular and stem cell biology during the past two decades, our understanding of vascular calcification has evolved from being perceived as a harmless, passive deposition of minerals to what we now consider a highly regulated, cell-mediated process that is strongly associated with chronic kidney disease (CKD) and confers increased risk for incident car

The capacitive biosensor technology can be utilized for the analytical detection of a variety of different compounds. By employing the electrical double-layer principle, it is possible to detect very low concentrations of the target analyte due the methods inherent high sensitivity. This affinity-based capacitive biosensor is a powerful tool also for the analytical detection of low molecular weigh

Uppsatsen syftar till att undersöka vilken roll den gode mannen för ensamkommande barn har när barnet ifråga är föremål för tvångsomhändertagande. Uppsatsen börjar med en definition av vilka som räknas som ensamkommande barn och vilka bestämmelser som finns kring dessa. Därefter går jag igenom den gode mannens roll och uppdrag och jämför med andra gode män. Sedan går jag kort igenom parters rättigThis essay aims to investigate the role of the guardian appointed to unaccompanied minors in Sweden, especially what role they have in cases of compulsory care. The essay defines unaccompanied minors and explores what regulations there are for them and investigates the role of the guardian compared to other representatives in Swedish law.

Numerical simulations of fluid-structure interaction of a water-filled tube with a free surface are conducted using an implicit partitioned coupling scheme. Abaqus and STAR-CCM+ are used for the solid- and fluid domains respectively. This application has stability issues, with the most severe turning out to be the added mass effect. Rayleigh β damping and grid flux under-relaxation has been used t

Vi bor i galaxen Vintergatan. En plats som vi kan kalla hemma i ett allt växande universum. Men hur mycket vet vi egentligen om våran galax? Det finns mycket som återstår att upptäcka om våran galax. Ett exempel på någonting som vi inte vet hittas när vi observerar den galaktiska disken. Detta är regionen som expanderar horisontellt från det galaktiska centrumet. Disken är uppdelad i en tunn ochThis paper discusses the effects of different types of contamination on 4MOST stellar spectra. Three main types of contamination were tested. These were, a smooth function over the continuum, changing the H-alpha line, and adding telluric contamination. By knowing how much these experiments affected the generated values, it was possible to understand the importance of avoiding overfitting or under

Densiteten I stadens utveckling utmanar oss arkitekter till att skapa bra arkitektur i stadsrummet. Staden växer och skapar nya förutsättningar i människans vardag. Staden förtätas och då brist på bra centralt placerad mark blir väldigt påfrestande så skapas nya urbana typologier. Jag vill i mitt examensarbete arbeta vidare på denna problematik och undersöka mer specifikt, hur ser bostaden ut i The density of the city’s development challenges us architects to create good architecture in the urban space. The city grows and creates new conditions in people’s everyday lives. The city is densified and when the lack of good centrally located sites becomes very challenging, new urban typologies are created. In my master thesis, I work further on this problem and investigate more on what hous

Frågan om utländska direktinvesteringar och främmande staters inflytande i Sveriges känsliga angelägenheter är en som aktualiserats mycket på senare år, inte minst på grund av det alltmer ansträngda omvärldsläget. Den första december 2023 antogs UDI-lagen, som ger möjlighet att granska investeringar i svensk skyddsvärd verksamhet, och eventuellt förbjuda dem, om de anses kunna vara potentiellt skaThe issue of foreign direct investments and the influence of foreign states in Sweden's sensitive affairs has been brought to the forefront in recent years, not least due to the increasingly strained global situation. On De-cember 1 2023, the Foreign Direct Investment Act (UDI-lagen) was adopt-ed, allowing for the audit of investments in Swedish companies preforming sensitive activities and th
