To determine the importance of the phosphorylation capacity of receptor kinase as well as the ability to serve as docking sites for SH2-domain-containing signal transduction molecules, we established pig aortic endothelial cell lines stably expressing kinase-active platelet-derived growth factor (PDGF) alpha-receptors together with kinase-inactive beta-receptors, and vice versa. After stimulation

Hip fractures are a major cause of hospital stay among the elderly, and result in increased disability and mortality. In this study from 1 April 2003 to 31 March 2004, the influence of optimised treatment of hip fracture on time to operation, length of hospital stay, reoperations and mortality within 1 year were investigated. Comparisons were made between the first 210 patients in the period and t

We present a variation of fractional tessellation to provide more uniformly distributed tessellation in screen space. Tessellation weights are added at the vertices for added flexibility and we show that the quality is improved at a minor cost.

After the “Venus Transit Conference” that took place at the University of Tromsø from June 2 to June 3, 2012, participants were given the opportunity to either stay in Tromsø until the night of June 5–6, or to participate in a voyage to Finnmark, where the historical sites Vardø, Hammerfest, and the North Cape were to be visited. This voyage culminated in the observation of the 2012 transit of Ven

Popular Abstract in Swedish Föreställ dig ett stort rum med bara en liten fyrkantig, ungefär tio centimeter stor, öppning på en av väggarna. Rummet har fem meter långa väggar och är flera meter högt. Golv, tak och alla andra väggar är helt utan öppningar och är inte genomskinliga. Man misstänker att temperaturen varierar mycket så att det kan vara varmt i en del av rummet och kallt i en annan. DärLight detection and ranging (lidar), a method for nonintrusive, single-ended, and range resolved measurements, has been developed and applied for combustion related diagnostics. Employing picosecond laser pulse durations and detectors providing temporal resolution on the order of picoseconds, lidar has been applied successfully for both quantitative temperature- and species concentration measureme

This paper describes how credit default swaps could be employed to create performance based executive compensation portfolios that reflect the value of a firm’s debt as well as equity; i.e. the total value of all a firm’s assets. We define so-called Asset Value Unit (AVU) compensation portfolios that work both for executive- and non-executive pay schemes in financial as well as non-financial firms

The application of nitrogen vibrational CARS thermometry to sooty, premixed, atmospheric pressure flames has been investigated using a Nd:YAG laser based system. It was found that laser-produced C2 radicals strongly absorb part of the fundamental band peak in the CARS spectrum. This was the most severe interference to the CARS signal. A quantitative investigation of temperature errors caused by th

If anyone begins to think about the term ultrasound, the first thing that comes to the mind is the fact that it is used in animal communications (e.g., bat navigation and dog whistles). Also, one may start to think that this term is familiar in daily life and has been used many times in medicine applications for foetal imaging, (SONAR). However, many questions come to the mind, such as, what is ha

In this article we analyze the initial phase (2004–2006) in the establishmentof the vocational degree of ’civilekonom’ [literally: ‘civil economist’] as aprocess of professionalization. Drawing upon ideas from discourse analysis,we investigate texts produced by ’Civilekonomerna’ [the union of economicsand business graduates], ’Lagstiftaren’ [the legislature], and the expert panelof the assessment

The use of external providers for the provision of information and communication technology (ICT) in small and medium-sized enterprises (SMEs) is expected to increase. At the end of the 1990s the concept of Application Service Provision (ASP) and Application Service Providers (ASPs) was introduced. This is described as one way for SMEs to provide themselves with software applications. However, it

Popular Abstract in Swedish På väg mot en universiell elliptisk lösare i två dimensioner Elliptiska partiella differentialekvationer används för att beskriva och modellera ett stort antal fysikaliska fenomen som ofta förekommer i industriella processer, till exempel värmeledning; elektromagnetisk spridning hos antenner; långsamma flöden exempelvis vid sedimentering av pappersmassa, eller elastiskThis thesis addresses solving elliptic partial differential equation using integral equation methods, with emphasis on accuracy, speed and stability. Of particular interest are such equations on non-smooth domains, and several different elliptic problems such as electrostatic and elastostatic ones are treated and solved in this setting.

AIM: The adiponutrin gene family consists of five genes (PNPLA1-5) coding for proteins with both lipolytic and lipogenic properties. PNPLA3 has previously been associated with adult obesity. Here we investigated the possible association between genetic variants in these genes and childhood and adolescent obesity. METHODS/RESULTS: Polymorphisms in the five genes of the adiponutrin gene family were
