In this paper, the focus is on numerical results from calculations of scattered direct waves, originating from internal sources in non-stationary, dispersive, stratified media. The mathematical starting point is a general, inhomogeneous, linear, first order, 2 × 2 system of equations. Particular solutions are obtained, as integrals of waves from point sources distributed inside the scattering medi
The rabbit knee joint was used to evaluate the inflammatory properties of immune complexes with different contents of antigen. Immune complexes made in vitro with antiserum from hyperimmunized rabbits and bovine serum albumin as antigen were injected into the joints. The reactivity of the individual animal was established by injection of normal rabbit serum into the contralateral joint. The number
Adaptive spectral estimation techniques are known to provide good spectral resolution and contrast even when the observation window (OW) is very short. In this paper two adaptive techniques are tested and compared to the averaged periodogram (Welch) for blood velocity estimation. The blood power spectral capon (BPC) method is based on a standard minimum variance technique adapted to account for bo
Abstract in French Cet article a deux objectif. À un premier niveau, nous présentons un survol de quatre aspects du DP français et leur acquisition par des apprenants adultes suédophones, à savoir l’existence d’un stade de noms dits « nus », le statut syntaxique de l’article défini, le placement de l’adjectif et l’accord en genre. À un deuxième niveau, nous souhaitons illustrer une méthode de travThis article has two objectives. At a first level we present an overview of four aspects of the French DP and its acquisition by adult Swedish speaking learners, namely the existence of a bare noun stage, the syntactic status of the definite article, the placement of the adjective and gender agreement. At a second level, we wish to illustrate a method in Research on Language Acquisition which is i
Among other nutrients of breast milk, the amino acid pattern is considered normative throughout infancy. Exclusive breastfeeding by a healthy mother should be the standard from birth to 6 months. During the breastfeeding period the protein intake is low in the human being compared too many other animals. The protein content in breast milk is about 1 g/1 00 ml and the daily protein intake approxima
Loss of the smooth muscle contractile phenotype is critical in atherosclerosis and in restenosis after angioplasty, but its early signals are incompletely understood. In this study, we have explored the role of transient receptor potential canonical (TRPC) proteins, which have been suggested to mediate store-operated Ca2+ entry (SOCE). Contractility of rat cerebral arteries in organ culture is pre

Materials and Methods: Monophasic action potential (MAP) were recorded, using the CARTO mapping system and NaviStar catheters, during sinus rhythm from the endocardium at 43 ± 15 LV or RV sites in 8 patients, at 61 ± 18 LV and/or RV sites in 10 pigs and during atrial pacing from the endo- and epicardium at 211 ± 54 LV and RV sites in additional 10 pigs. Local activation time (AT), MAP duration (MA
A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest supersymmetric particle is the gravitino, is presented. Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies. No evidence f
The pK(a) of a C-13-enriched fatty acid probe, tetradecanoic acid, was investigated in a variety of sugar-derived (APG) surfactants by using C-13 NMR to monitor the chemical environment of the probe during titration with base. There was an increase of approximately 2 pK(a) units for the probe within the micellar systems compared to the value of acetic acid in water. Analysis shows that the interfa
Objective: Norepinephrine (NE) is elevated in pregnancies complicated by preeclampsia (PE). Specific uptake of NE by the NE transporter (NET) plays a central role as regulator of NE levels. Expression of NET is reduced in placentas from PE pregnancies. To study adverse fetal effects of reduced NET expression on the placental buffering capacity, the NET was pharmacologically blocked by a specific u
Purpose: Free prostate specific antigen (PSA) in serum consists of heterogeneous molecular subforms. Recently we developed an immunoassay for selective measurement of a subfraction of free PSA called intact PSA, which has been shown to be closely associated with prostate cancer. We assessed the ability of serum intact PSA to discriminate between benign and malignant prostatic disease. Materials an
Popular Abstract in Swedish Cafeterian i Malmö Musikhögskola förvandlas två gånger om året till de passionerades mötesplats: När terminens ”Gambiastudenter” återvänder efter sina tre veckors fältarbete och skola med palmer som klassrumsväggar, möts de av veteranerna, de som redan varit där och som förstår att tolka entusiasmen. Det handlar inte om den vitalitet som alstrats av solen, färgerna och The present study seeks to examine attitudes to teaching and learning among jalis in the Gambia. Although this is the main focus, the horizon of which the study is carried out, analysed and discussed, is the development of music teacher education in Sweden during the last three decades, and of which I have been a participant. The intention of the study is to expand current views on music teaching
The risk of seizure recurrence within the first year of life was evaluated in infants with neonatal seizures diagnosed with a combination of clinical signs, amplitude-integrated electroencephalogram (EEG) monitoring, and standard EEG. Fifty eight of 283 (4.5%) neonates in tertiary level neonatal intensive care had seizures. The mortality in the infants with neonatal seizures was 36.2%. In 31 survi
A number of screening procedures are offered by midwives during pregnancy and the number is increasing rapidly. The measurement of nuchal translucency is a fairly new ultrasound method for antenatal screening, primarily for Down syndrome. The results give a better risk calculation than maternal age alone and can mean a decrease in the number of invasive procedures needed to identify this syndrome
