In this paper, we investigate the importance of taking frequency-dependent temporal phenomena into account in audio coding. We do this in the context of sinusoidal modeling of audio signals by applying amplitude modulation to the sinusoidal components. Traditionally, audio coders use a fixed time-segmentation for all frequencies despite that it is well-known that the time-frequency resolution of t

Popular Abstract in Swedish Människor har sedan länge känt till att deras hälsotillstånd varierar beroende på årstid. Vissa av oss drabbas av påtagliga årstidsbundna hälsoproblem och så pass hårt att viktiga funktioner påverkas. Även om dessa företeelser observerades före kristen tidräkning, är bara sedan mitten av förra seklet som man studerat dem vetenskapligt. Det har blivit klarlagt att alla vSeasonal Affective Disorder with depressive episodes during the autumn/winter seasons (winter depression) is common. Outpatients with winter depression were studied regarding temperament, psychopathology, social characteristics, psychosocial functioning and the neuropeptides corticotropin - releasing hormone (CRH) and neuropeptide Y (NPY), which are known to be involved in stress-regulation. The t

During the latest years the research on the effects of moisture on clothing system has been boosted. New information has revealed phenomena, e.g. “heat pipe” effect with its condensation-evaporation cycle(s) that has not been considered earlier in prediction of physiological reactions or evaluating clothing properties. Considering the material properties, e.g. the evaporative resistance measuremen

The term ‘strategic use of procurement’ indicates that the procurement (also referred to as sustainable procurement) is about more than just saving money. Other important interests such as social and environmental considerations can be promoted through public procurement. Procurers can, according to newly proposed Directives on public procurement, make better use of public procurement in support o

Popular Abstract in Swedish Manniskan utsatts dagligen for sjukdomsframkallande bakterier och virus, vilka maste tas omhand och oskadliggoras. Var hud och slemhinnor fungerar som ett forsta fysiskt och biokemiskt skydd. De som tar sig forbi denna barriar angrips av vart immunforsvar. De vita blodkropparna ar de celler, som snabbast rycker ut till vart forsvar och ater upp och forstor angriparen. DT cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. Mutations in the SAg MHC class II a-chain binding site reduced the number of responding T cells expressing particular TCR Vb chains, whereas mutati

A critical comparison of two mid 19th century versions of the story of As’ad al-Shidyâq, a young Maronite who became the first Protestant sympathiser in Lebanon; the first version written by an American missionary (Isaac Bird), the second by a Lebanese intellectual (Butrus al-Bustani) who became a Protestant. The comparison reveals differences between expatriate and indigenous perceptions of Prote

To explore attitudes toward female genital cutting (FGC) in a migration perspective, qualitative interviews were conducted with men and women from Ethiopia and Eritrea in Sweden. We found firm rejection of all forms of FGC and absence of a guiding motive. Informants failed to see any meaning in upholding the custom. We conclude that children of Ethiopian or Eritrean parents resident in Sweden run

An overview of optical techniques for environmental monitoring is presented. Range-resolved measurements of atmospheric pollutants can be performed using the differential absorption lidar technique. Fluorescence lidar allows assessment of vegetation status and also the conditions of the facades of historical buildings. Diode lasers provide particularly realistic schemes for atmospheric gas analysi

This paper describes a general picture of efforts to provide women with equal opportunity both on a national political level, and within academia. A report of recent activities within the newly formed National Division for Women in Physics within the Swedish Physical Society is also given

This article deals with multi-unit questioning turns used in different genres of institutional interactions. Analyzing in detail a corpus of about 400 multiunit questions from health care interactions, court trials, police interrogations, and social welfare office talks from Sweden and Finland (all in the Swedish language), a number of sequential patterns are established. Some of these sequential

Normal ageing in men is associated with a physiological decline in testosterone levels, but adverse environmental or psychosocial factors may also impair testosterone secretion and cause secondary biological changes. In a number of observational or experimental studies in both animals and man, it has been possible to study the influences on gonadal function of stressful life situations. To underst

Popular Abstract in Swedish Mellan 15 och 20 % av de patienter som kommer för behandling av gallstenssjukdomen (stenar i gallblåsan) har samtidigt stenar i de djupa gallvägarna (förbindelsegången mellan lever-gallblåsa och tolvfingertarmen). Hos yngre patienter är andelen endast 7-8 %, medan den i äldre patientgrupper kan vara 50 % eller mer. Traditionellt har stenarna i gallgången avlägsnats samtOpen surgical versus endoscopic treatment of CBD stones in 80 elderly not cholecystectomized patients revealed a similar efficacy of stone clearance and early major complication rates, as well as total complication rates and hospitalization time in the two groups during 5 to 9 years follow-up. However, more patients in the endoscopically treated group died from heart disease, suggesting surgery to

Three issues characterise the background to the MECCA study: A) Throughout Europe, most patients with severe forms of psychotic disorders are cared for in the community. The challenge now is to make processes in community mental health care more effective. B) There are widespread calls to implement regular outcome measurement in routine settings. This, however, is more likely to happen, if it prov

Deviances in early event-related potential (ERP) components reXecting auditory and phonological processing are well-documented in children at familial risk for dyslexia. However, little is known about brain responses which index processing in other linguistic domains such as lexicon, semantics and syntax in this group. The present study investigated eVects of lexical-semantic priming in 20- and 24

To meet the demands of high electrical efficiencies in combination with low emissions for gas turbine-based power plants, wet cycles have gained new interest. The combustion chamber is a key component in such a power plant. Detailed investigations are necessary to gain insight into the formation of hazardous emissions such as CO and NOx. In this paper, computational fluid dynamics (CFD) has been e

The increasing semiconductor functionality relies on more complex integrated circuits with higher component densities. Miniaturisation and its implications on resource consumption in semiconductor facilities have been fairly well explored in a number of life cycle assessment (LCA) studies, which show that, in spite of the growing product complexity, resource intensities per product unit are gradua
