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

Background: The maintenance of postural control is fundamental for different types of physical activity. This can be measured by having subjects stand on one leg on a force plate. Many studies assessing standing balance have previously been carried out in patients with ankle ligament injuries but not in patients with ankle fractures. The aim of this study was to evaluate whether patients operated

BACKGROUND: BRCA1 and BRCA2 are the two major susceptibility genes involved in hereditary breast cancer. This study was undertaken to provide reliable population-based estimates of genetic influence and to characterize the nature and prevalence of BRCA1 and BRCA2 germline mutations in early-onset breast cancer.METHODS: In a series comprising all women diagnosed with breast cancer under the age of

In this paper, we consider fundamental limitations for DOA estimation with arbitrary lossless antennas or antenna arrays inserted inside a sphere. Spherical vector modes and their associated equivalent circuits and Q factor approximations are employed as a general framework for the analysis. The classical broadband matching theory by Fano is extended to a general multiport S-parameter model of the

The aim of this study was to demonstrate electronic speckle pattern interferometry (ESPI) as a powerful tool in determining diffusion coefficients and partition coefficients for proteins in gels. ESPI employs a CCD camera instead of a holographic plate as in conventional holographic interferometry. This gives the advantage of being able to choose the reference state freely. If a hologram at the,re

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

How individuals respond to habitat heterogeneity is usually measured as variation in range size and by ranking the relative importance of habitat types (habitat selection). The combined effect of how individuals incorporate different habitat types in their home ranges and allocate their time budget between them is rarely derived. Additionally, when home range size varies between individuals, habit

Denna rapport handlar om socialtjänstens kunskapsbildning. I dess inledning konstateras att kunskapsutveckling är något som ligger i tiden. Från flera håll pekas det på att det sker stora och viktiga insatser på detta område medan socialtjänsten av någon anledning tycks ha hamnat i skamvrån. I själva verket riktas det från flera oberoende håll stark kritik mot dess verksamhet och det hävdas att ar

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

1 The present study addressed the role of neuropeptide (NPY) Y-2 receptors in neurogenic contraction of mesenteric resistance arteries from female spontaneously hypertensive rats (SHR). Arteries were suspended in microvascular myographs, electrical field stimulation (EFS) was performed, and protein evaluated by Western blotting and immunohistochemistry. 2 In vasopressin-activated endothelium-intac

A recent study carried out by our group demonstrated that exogenous dopamine increases the somatostatin (SS) receptor–effector system in the rat striatum. The present study examined the participation of the D1- and D2-dopaminergic systems in the modulation of the rat striatal SS receptor–effector system by use of the D1-receptor agonist and antagonist SKF 38393 and SCH 23390, respectively, and the

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

High resolution core level spectroscopy in combination with density functional theory calculations are used to study the satellite feature of the Ru-3d(5/2), core level spectrum whose interpretation is still a matter of debate. We present evidence that the satellite peak is not related to any structural properties of the RuO2(1 1 0) surface. The binding energy shift between the Ru-3d(5/2) componen

A study on a possible solar wind interaction with the North AtlanticOscillation (NAO) is performed. Results are presented suggesting arelationship between the NAO index and the electric field strength E ofthe solar wind. A possible scenario for the suggested interaction isthat an electromagnetic disturbance is generated by the solar wind inthe global electric circuit of the ionosphere. This distur
