In this paper, a new frequency offset correction approach for OFDM is proposed to track a wider range of offsets than conventional proposals, without devoting specific pilot symbols for synchronization. This can be attained since, in coherent OFDM, channel estimation is usually performed employing pilot-symbol assisted-modulation (PSAM), based on inserting known symbols in the time-frequency grid.
Popular Abstract in Swedish Det samlade temat för de sju artiklarna i denna avhandling är att se på hur modern national-ekonomiska teori, som behandlar problem rela-terade till förekomsten av asymmetrisk infor-mation, kan användas för att studera insatser för åstadkomma bättre hälsa. Artiklarna rör dels vård på sjukhus,dels produktionen av läkemedel. För sjukhusen handlar det om hur man via olika The common theme of this thesis is the analysis of asymmetric information when applied to the market for health care production. The thesis consists of six more or less independent papers and an introduction to the thesis were purpose and methodology are stated (part one). Part two is an investigation into the pricing of pharmaceuticals in Sweden. This chapter deals with issues such as cost sharin
The five ribosomal P-proteins, denoted P0-(P1-P2)(2), constitute the stalk structure of the large subunit of eukaryotic ribosomes. In the yeast Saccharomyces cerevisiae, the group of P1 and P2 proteins is differentiated into subgroups that form two separate P1A-P2B and P1B-P2A heterodimers on the stalk. So far, structural studies on the P-proteins have not yielded any satisfactory information usin
Aim: The relationship between support at home and rehospitalization has not been extensively studied until now. In particular, little is known about the impact of being assisted by migrant care workers (MCW) and rehospitalization. We aimed at investigating such a relationship in a population of older patients discharged from hospitals. Methods: Our series consisted of 506 patients aged 65 years or
Total gastrectomy or resection of the acid-producing part of the stomach (fundectomy) in the rat induced a marked and rapid reduction in bone wet weight, ash weight, and density (expressed as ash weight in mg/mm3 bone). Bone volumes were also affected but not as much. The radius, sternum, tibia, and femur were studied. Three weeks after gastrectomy the bone ash weight was reduced by almost 30% and
The single Trp of human cystatin C, Trp-106, is located in the second hairpin loop of the proteinase binding surface. Substitution of this residue by Gly markedly altered the spectroscopic changes accompanying papain binding and reduced the affinity for papain, actinidin, and cathepsins B and H by 300-900-fold. The decrease in affinity indicated that the side chain of Trp-106 contributes a similar
Abstract in UndeterminedA complex earth system model, simulating atmosphere and ocean dynamics, marine biogeochemistry, terrestrial vegetation and ice sheets, was used to study feedbacks between the terrestrial biosphere and climate with a set of long-term climate change ensemble experiments. CO(2) emissions were assigned according to historical data and the IPCC SRES scenarios B1, A1B and A2, fol
Populärvetenskaplig sammanfattning Oxidativa modifieringar av S100A9 S100A9 är ett protein i kroppen som får en förändrad struktur och funktion när det reagerar med syre. De strukturella förändringarna kallas oxidativa modiferingar. För att förstå processen skulle man kunna jämföra S100A9 med järn. När järn kommer i kontakt med syre får det en rödaktig färg och strukturen går från att vara stark tThe aim of this project was to examine how S100A9 binding to target molecules was affected by structural modifications with oxidizing agent in vitro. S100A9 was cultivated, purified and oxidative modifications were induced. The oxidative modifications where characterized with tryptohan fluorescence, Surface Plasmon Resonance technique (SPR) and MALDITOF-MS. To get access to protein to study recomb
During the last fifteen years the world has developed sufficiently and therefore has changed radically. As a result of globalisation and the technical development new threats and challenges has emerged. As a result of this, the security policy has also changed. In this thesis I have studied Försvarsberedningens reports from 1998 to 2013, with the purpose of describing the change in threats and the
Syftet med uppsatsen är att redogöra för varumärkesrätten och då avseende vilket skydd som finns att få för en varumärkesinnehavare av ett väl ansett varumärke. Varumärket har under de senaste åren kommit att få en helt annan innebörd än tidigare. Ett varumärke har blivit ett från varorna fristående subjekt med ett egenvärde. Ett sådant varumärke, som i många fall uppkommit genom massiva investeriMy main ambition with this thesis is to describe a trademarks protection. Primarily what protection that is available for a trademarks owner of a well- known trademark i.e. a reputation mark. The concept of trademark has in recent years come to have a totally different meaning than it had just a few years ago. The trademark is separated from the goods, with an intrinsic value. A trademark, which i
Through this degree project, we have come up with effective methods in the computer program ArchiCAD that architects use during project planning for buildings. The purpose of the degree project was to examine how architects and software developers use ArchiCAD effectively, in the building process so that also information transfer to other actors works. The theory of the degree project deals with t
The primary rule of absolute duty to prosecute is stated in 20:6 RB. This means that the prosecutor is obliged to engage prosecution when there is sufficient evidence for a conviction. The possibility of waiver of prosecution is stated in 20:7 RB and is an exception from the absolute duty of prosecution. The prosecutor can decide to waive prosecution for minor offense not resulting in any other pe
Thomas Quick, numera Sture Bergwall, har kallats Sveriges värste seriemördare. Nu krackelerar den bilden. Sedan Thomas Quick tog tillbaka sina erkännanden har han praktiskt blivit friad från samtliga åtta mord han blivit dömd för. Syftet med framställningen är att utreda hur domen gällande Appojaurefallet kunde rämna bara för att den tilltalade Thomas Quick tog tillbaka sitt erkännande. Mer konkThomas Quick, now Sture Bergwall, has been called the worst serial killer in Sweden’s history. That picture is now falling apart. Since Thomas Quick retracted his confessions he has practically been cleared from all eight murders he was convicted for. The purpose of this essay is to investigate how the judgement in the Appojaure case could fall apart only because the defendant retracted his confe
Background: Esophageal squamous cell carcinoma (ESCC) is a genetically complex tumor type and a major cause of cancer related mortality. Although distinct genetic alterations have been linked to ESCC development and prognosis, the genetic alterations have not gained clinical applicability. We applied array-based comparative genomic hybridization (aCGH) to obtain a whole genome copy number profile
Purpose: To test various ways of combining creatinine and cystatin C in equations to predict glomerular filtration rate (GFR). Material and methods: Performance of the following expressions to predict GFR was compared with measured GFR (iohexol clearance, mL/min/1.73 m(2)) in 857 patients: (i) Lund-Malmo creatinine equation, (ii) Grubb cystatin C equation, (iii) arithmetic mean of (1) and (2), (iv
As one of the main objectives of the Bologna process, employability has become a central concept to consider for universities when designing higher education. Although the universities are required implementing employability, there is no defined meaning of what employability actually is which implies a significant autonomy for university teachers in how to interpret the concept and fill it with me
Föreliggande uppsats är ett examensarbete i juris kandidatprogrammet. Uppsatsen är skriven inom området familjerätt, mer preciserat inom successionsrätten. Uppsatsen behandlar efterlevande makes arvsrätt genom att gå igenom de regler som finns på området i Sverige, Norge och Danmark. Inom arvsrätten har det länge varit släktskapet som styrt vart arvet efter en avliden skall hamna. I dagens samhäThis thesis is written in the field of family law, more precisely about the law of succession. The thesis describes the spouse’s right to inheritance by comparing the rules in Sweden, Norway and Denmark. In the Swedish law of succession, it has long been the kinship that controlled where the estate of a deceased person should end up. The legislature has to some extent moved away from this. It is

Finally a description of a method to transfer data from the current database to the new is given, together with a smaller implementation. CIDS – Center of Investigation of Demography and Health is located in Nicaragua, Le
År 2009 blev Europeiska Unionens stadga om de grundläggande rättigheterna juridiskt bindande nästan ett decennium efter det att processen att utarbeta en stadga hade påbörjats. Stadgans status som ett juridiskt bindande dokument väcker naturligtvis nya frågor om det framtida skyddet av mänskliga rättigheterna i Europa samt stadgans förhållande till Europakonventionen såväl som medlemsstaternas konIn 2009, the Charter of fundamental rights of the European Union became legally binding almost a decade after the process to draft a Charter had begun. Naturally, the Charter’s status as a legally binding document raises new questions about the future protection of human rights in Europe and the Charter’s relation to the European Convention on Human Rights as well as the Member States’ constitutio
This report describes the results obtained from fire tests in a 1/3-scale room. The aim of the study was to investigate how changes in external radiation and oxygen supply affect the production of smoke and toxic gases. The ventilation was varied to simulate under- and well-ventilated fires. The thermal exposure to the materials was varied to simulate fires of different sizes. Fifty-nine tests wer
