Popular Abstract in Swedish Denna avhandling består av 5 fristående uppsatser i makroekonomi. Den första uppsatsen behandlar agregerad privat konsumtion. Det har nyligen föreslagits att hushållens konsumtion av icke-varaktiga varor reagerar asymmetriskt på positiva och negativa inkomstförväntningar. I denna uppsats undersöker vi huruvida detta är beroende på hur hushållens förväntningar modelleraThe first essay reexamines the proposed presence of so-called loss aversion in aggregate consumption. Recent empirical and theoretical studies have suggested, that consumption growth reacts asymmetrically to positive and negative expected income growth. After investigating the case for Swedish consumption using survey data, and a panel of annual observations on 15 OECD countries, we conclude that

Popular Abstract in Swedish Demens är ingen enhetlig sjukdom utan ett syndrom dvs en beteckning på en grupp symtom, som beskriver en långvarig försämring av hjärnans psykiska funktioner. Demens kan ha olika klinik profil och orsakas av olika skador och sjukdomar. Den vanligaste demenssjukdomen är Alzheimers sjukdom. Kring denna sjukdom finns mycket forskning gjord. Vaskulär demens är den näst vanlDuring the period (1976-1995) a total of 175 consecutive patients (m 88/f 87) with neuropathologically verified vascular dementia (VaD) were examined. 22 patients with pure Alzheimer's Disease (AD) were also studied. All patients were diagnosed and followed at the Department of Psychogeriatrics (Lund University Hospital). The neuropathological examination revealed VaD, sometimes with additional co

Translocations involving an immunoglobulin (IG) locus are a recurring theme in B cell neoplasia. The rearrangements lead to the joining of an IG gene with a (proto)oncogene, whereby the latter comes under the influence of transcription-stimulating sequences in the constitutively active IG locus resulting in deregulation of the oncogene and neoplastic growth. We present here three cases of B cell n

OBJECTIVE: To investigate whether patients with severe radiographic osteoarthritis (OA) have a different outcome at one year after total hip replacement than patients with moderate radiographic OA. To investigate sex related differences in preoperative radiographic and self reported status and in postoperative outcome.METHODS: 184 patients (96 women) with a mean age at surgery of 71.4 years (50-92

A stirred tank membrane reactor is used to study the kinetics of polygalacturonic acid (PGA) enzymatic hydrolysis. The reactor operates in semicontinuous configuration: the native biopolymer is loaded at the initial time and the system is continuously fed with the buffer. The effect of retention time (from 10 1 to 142 min) and membrane molecular weight cutoff (from I to 30 kDa) on the rate of perm

AIM: To study the cellular transport of L68Q cystatin C, the cystatin variant causing amyloidosis and brain haemorrhage in patients suffering from hereditary cystatin C amyloid angiopathy (HCCAA). METHODS: Expression vectors for wild-type and L68Q cystatin C were constructed and used to transfect mouse NIH/3T3 cells. Stable cell clones were isolated after cotransfection with pSV2neo. Clones expres

Popular Abstract in Swedish Kambrium är en tidsperiod i jordens historia som sträckte sig från 542 till 488 miljoner år sedan. Denna period kan vidare delas in i tre epoker: tidigkambrium, mellankambrium och furongian. I kambriums inledningsskede ägde en intensiv och snabb utveckling av livet rum och det var under denna tid som i stort sett alla kända djurstammar utvecklades. Denna viktiga händelsThis thesis is based on studies of upper middle Cambrian through Furongian strata in Scandinavia with focus on trilobite biostratigraphy, taxonomy, paleoecology, and intercontinental correlation. The material studied derives mainly from Västergötland and Scania, southern Sweden. Three new trilobite species are described: Macropyge (Promacropyge) scandinavica, Elkanaspis kinnekullensis, and Parabol

BACKGROUND: The way GPs work does not appear to be adapted to the needs of depressive patients. Therefore we wanted to examine Swedish GPs' conceptions of depressive disorders and their treatment and GPs' ideas of factors that may influence their manner of work with depressive patients. METHODS: A postal questionnaire to a stratified sample of 617 Swedish GPs. RESULTS: Most respondents assumed ant

Analysis, assessment, and design of advanced wire-line transmission schemes over multipair copper cables require accurate knowledge of the channel properties. This paper investigates modeling of multiconductor cables based on interpair impedance measurements. A unified approach to the application of the "Cioffi" model is introduced. The direct measurement approach of the underlying interpair imped

By using the density matrix theory of interaction between light and matter, and relevant parameter calculations of the relaxation rate, the dipole matrix elements and the ion density for a three-level ladder model, we have discussed theoretically the possibility to realize electromagnetically induced transparency (EIT) in Er3+:YA1O(3) crystal.

The development of inflammatory bowel diseases (IBD) and colon cancer (CC) has been shown to involve the up-regulation of inflammatory mediators and the machinery producing them such as the eicosanoids. Changes in the expression of extracellular matrix proteins and their related integrin receptors have also been shown to be important in the advancement IBD and CC. In light of this, we have investi

A cDNA encoding the mature human cysteine proteinase inhibitor cystatin C was fused to the coding sequence for the Escherichia coli outer membrane protein A signal peptide, and the recombinant gene was expressed in E. coli under the control of the λ PR promoter, an optimized Shine-Dalgarno sequence and the λ cI 857 repressor. When induced at 42°C, such cells expressed large amounts of recombinant

Popular Abstract in Swedish Riskanalys och insatsplanering är viktiga delar av ett riskhanteringsarbete. Denna studie har visat att det är möjligt att använda brandtekniska ingenjörsmodeller för att bedöma utvecklingen av bränder och det uppkomna behovet av släckmedel. Brandkårsdata från London användes för att studera sambandet mellan brandstorleken och räddningstjänstens insats. Dessa data, tillRisk analysis and intervention planning are important in fire prevention and risk management strategies. This study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media. Data from the London Fire Brigade (UK) were used to investigate a possible correlation between the

Popular Abstract in Swedish Stroke är en vanlig och mycket allvarlig form av hjärt-kärlsjukdom som uppkommer på grund av försämrat blodflöde i en del av hjärnan. Eftersom hjärnan är extremt beroende av kontinuerlig tillförsel av syre och näringsämnen leder tillståndet snabbt till hjärnskada. Det finns tre typer av stroke; hjärninfarkt, hjärnblödning och subaraknoidalblödning (blödning under en hjäThe present thesis aimed to examine how ischemic stroke affects the vascular endothelin and angiotensin systems in cerebral arteries. To study vascular receptor changes in ischemic stroke transient focal ischemia was induced in rats. In addition, rat cerebral arteries and arterial smooth muscle cells were cultured for further analysis of cerebrovascular receptor regulation. For functional studies
