Phenotypic modulation of vascular smooth muscle in organ culture

Popular Abstract in Swedish Människans blod cirkulerar runt i kroppen genom dess många blodkärl. Blodkärlen är till största del uppbyggda av två slags celler; endotelceller och glatta muskelceller. Endotelcellerna är placerade innanför de glatta muskelcellerna i blodkärlet och deras uppgift är att forma en barriär mot blodet. De glatta muskelcellernas funktion är att reglera blodflödet genom blodkContraction of blood vessels for the regulation of blood flow and pressure is dependent on vascular smooth muscle cells (VSMC) located in the medial layer of the vascular wall. Adult, differentiated VSMC have a well developed contractile system and a low rate of proliferation. Under the influence of hormones, growth factors, inflammatory mediators and tissue factors, cells may modulate to a ”synth

A factorial experimental evaluation of automated test input generation – Java platform testing in embedded devices

Background. When delivering an embedded product, such as a mobile phone, third party products, like games, are often bundled with it in the form of Java MIDlets. To verify the compatibility be- tween the runtime platform and the MIDlet is a labour-intensive task, if input data should be manually generated for thousands of MIDlets. Aim. In order to make the verification more efficient, we investiga

Impact of Open source ERP Systems Development on ERP systems Diffusion among SMEs

The interest in open source is high, which also goes for enterprise resource planning (ERPs) systems. In this article, we focus on the combination of open source and ERPs, and specifically on what role open source ERPs plays in the diffusion of ERPs among small and medium sized enterprises (SMEs). To be able to explain the interest in open source ERPs, we look into challenges, about which a propri

Initial tests of a new phantom for investigation of spatial resolution, partial volume effect and detectability in nuclear medicine tomography

Abstract in UndeterminedA new phantom has been designed that can provide simultaneously different target to background activity ratios with a linearly changing diameter of lesions. The purpose of the study was to describe and perform initial measurements with the phantom aimed to characterize different nuclear medicine tomographic systems and reconstruction algorithms in their performance and beha

Somatostatin and neuropeptide Y in cerebrospinal fluid: correlations with severity of disease and clinical signs in Alzheimer's disease and frontotemporal dementia

Alzheimer's disease (AD) and frontotemporal dementia (FTD) are the most common types of progressive neurodegenerative disorder in our catchment area. The distribution of cortical degeneration in FTD is mainly the reverse of that in AD, while there are both differences and similarities in the clinical characteristics. Somatostatin and neuropeptide Y (NPY) are neuropeptides with a widespread distrib

Statistics of temperature and potential fluctuations induced by coherent single particle sources

The prospect of time controlled information processing with individual electrons in nanoscale systems provides strong motivation for investigations of coupled charge and energy transport properties of single electron sources. Building on our recent work [F. Battista et al., Phys. Rev. Lett. 110, 126602 (2013)] we investigate theoretically the statistical properties of temperature and potential flu

A Statistical Theory of Shape

We study the statistical theory of shape for ordered finite point configurations, or otherwise stated, the uncertainty of geometric invariants. A general approach for defining shape and finding its density, expressed in the densities for the individual points, is developed. Some examples that can be computed analytically are given, including both affine and positive similarity shape. Projective sh

Datakommunikation och nätverk

Datakommunikation och nätverk ger en heltäckande och lättillgänglig redogörelse av modern datakommunikation. Boken är ett alternativ till internationella textböcker i ämnet, innehållet speglar kunskapsbehovet hos yrkesverksamma ingenjörer och ger de kunskaper som krävs på ett pedagogiskt och kärnfullt sätt. Boken innehåller förutom övningar även lästips och hänvisningar för den som vill söka fördj

Klassrummets mikrovärld

Abstract This dissertation examines the educational situation from a social psychological perspective. The study is based on an empirical material from two school classes at a Swedish high school. The data have been collected through video documentation and direct observation. A number of brief episodes have been transcribed in detail, and are interpreted and analyzed in the light of interactioni

Differential migration in raptors

Differences between ages, sexes and populations in the timing of migration at Falsterbo, Sweden and in the choice of wintering site among raptors in Scania were investigated. Competition and dominance is the best primary explanation to the results. In most cases the more competitive adults winter north of juveniles and the larger females north of males. Moult strategy is probably one of the most i
