The emerging concept of cognitive radios offers a way to use the limited radio-spectrum more efficiently by allowing networks and nodes to adaptively vary their parameters. An important element in the successful implementation of cognitive radios is the ability to estimate the varying state of spectrum usage in a wide-band channel quickly and at minimum cost. In this work, we utilize a powerful no
The plutonic rocks in the Western Segment of the Southwestern Swedish Gneiss Complex show a distinct geochemical evolution. The 1.6 Ga Åmål granitoids and Slottsbron migmatites are a quartz dioritic to granodioritic, calc-alkaline rock suite with smooth, but somewhat fractionated, REE and other trace-element patterns. The younger microcline granites of the 1.5 Ga and 1.3 Ga generations are evolved
Popular Abstract in Swedish I mitt arbete som neuropsykolog vid minnesmottagningen på psykogeriatriska kli¬niken (numera VO kognitiv medicin) vid Universitetssjukhuset i Lund har jag träffat många patienter som beskrivit besvärande minnessvårigheter i sin vardag. Patienterna berättade om svårigheter att lära sig nya rutiner på arbetet, att komma ihåg namn eller var de hade lagt sina saker. Många aThe overall aim of this thesis was to enhance the understanding of patients with subjective memory complaints. The thesis is based on three empirical studies examining middle-aged and young old (< 70 years) non-demented patients assessed at a memory clinic. In the first study the personality characteristics of the patients were compared with a Swedish normative sample. The patients scored higher o
Popular Abstract in Swedish Proteiner är stora kedjelika molekyler som syntetiseras i cellen med utgångspunkt från arvsmassan, DNA. I alla organismer har proteinerna en mängd uppgifter som kan sträcka sig allt ifrån att vara byggnadsmaterial i senor och bindväv till att fungera som avancerade molekylära maskiner i organismens energiomsättning. I stor utsträckning reglerar olika proteiner också bilAbstract. This thesis describes factors that are rate limiting for the folding of two small proteins, U1A and CI2 which fold without accumulating intermediates. The [GdnHCl] dependencies of the unfolding- and refolding kinetics of U1A display downward curvatures. However, as the curvatures are precisely matched and no indications of formation of partially structured intermediates are seen, the fol
Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore, when a modern office building (new construction) with larger glazing areas was planned, an investigation was carried out to determine the possibilities to: - efficiently use the increased access to daylight and thereby reduce the use of electricity for light
The article discusses if it is possible to bring Victor Turner’s work on liminality and ritual together with Roy Rappaport’s thought-provoking ritual theory and approach the contemporary ecological crisis in new ways. Specifically, it examine if we creatively can employ Turner’s concept of liminality and his understanding of a liminal passage as a metaphorical vision of re-embedding humanity withi
Popular Abstract in Swedish Extrakt från växten Artemisia annua har dokumenterats för sina anti-malaria egenskaper. Substansen är en mycket effektiv medicin mot malaria och hjälper även mot de former där multi-resistens utvecklats.1979 presenterades strukturen på den aktiva substansen. Den benämns artemisinin och är uppbygd av femton kol innehållandes en peroxid-brygga (två syre kopplade till varaPlants produce a multitude of different compounds that may have biotic effects. Artemisia annua, produces a compound used as a drug against multi-drug-resistant strains of Plasmodium falciparum, the parasite causing malaria. The compound, artemisinin, is a sesquiterpene and is an essential component for the production of artemisinin drugs against malaria. In a first critical step of the biosynthes
Phenomenology and hermeneutics have long been promoted as sources of inspiration for better information system (IS) design. Practical approaches to applying these philosophical ideas have been awaited for just as long. This paper offers a review of one practitioner’s experience in devising a theoretical and methodological ‘toolkit’ via which these disciplines’ principles have been applied in actua
Popular Abstract in Swedish Traditionellt har effekten av behandling inom kärlkirurgi främst utvärderats med objektiva mått, som till exempel beräkning av ankelindex och gångsträcka. Dessa data ger värdefull information men de återger inte hur patientens klarar sitt dagliga liv eller hur behandling återverkar på deras livskvalitet. Detta styrks i tidigare forskning som visar att korrelationen mellThe aim of this thesis was to assess quality of life in patients with varying degrees of lower limb ischaemia before and after revascularisation, to assess quality of life in relation to the degree of ischaemia and the respondents’ sense of coherence (SOC) and in comparison with a healthy control group, and to compare two different quality of life instruments regarding their usefulness as outcome

Popular Abstract in Swedish Många av de äldre patienterna som är inlagda på sjukhus eller som bor i särskilda boenden inom äldreomsorgen är idag undernärda. En sammanställning av Socialstyrelsen över svenska studier under de senaste 20 åren visade på en genomsnittlig frekvens av undernäring på 28%. Ett otillräckligt kostintag leder till undernäring. Kroniska sjukdomar är ofta en bakomliggande orsThe aim of this thesis was to develop and test the feasibility of a dietary record routine, where nursing staff assess the patient’s food and fluid intake based on standardised portion sizes and household measurements. The energy intake (EI) was studied with a dietary record in 61 geriatric patients. During the 6-month follow-up 11 patients died and an EI below median (1378 kcal) was associated w
