This paper investigates the use of data-adaptive spectral estimation techniques for blood velocity estimation in medical ultrasound. Current commercial systems are based on the averaged periodogram, which requires a large observation window to give sufficient spectral resolution. Herein, we propose a novel data-adaptive method to form the blood velocity spectral estimate. The method is evaluated u

Methods of VUV electron beam ion trap (EBIT) spectroscopy are applied to the study of Pm-like tungsten (W13+). These data show that theory appears well capable of dealing with these multi-electron (61) ions, at least for high ionization stages. A comparison of other spectroscopic methods applied to the study of other ions of the Pm I sequence is also given, and finally a search for the Pm-like W l

OBJECTIVE - we sought to study the frequency of P-cell-specific autoantibody markers in women with gestational diabetes mellitus (GDM) and to follow these women to estimate the risk of later development of type I diabetes. RESEARCH DESIGN AND METHODS - Of 385 pregnant women with GDM during 1995-2005 in the district of Lund, 24 (6%) women were found positive for at least one of the following: islet

A novel insertion device for electron storage rings, called the MAX-Wiggler [Nucl. Instr. and Meth. A 467-468 (2001) 118], has been constructed at MAX-lab. The MAX-Wiggler is a cold bore superconducting wiggler magnet with 47,3.5 T poles and a period length of 61 mm. It is designed for the production of X-rays at the 1.5 GeV electron storage ring MAX-II [Nucl. Instr. and Meth. A 343 (1994) 644] at

Several unconventional accelerator technology solutions were introduced in the MAX II electron storage ring during the 1990s, such as quadrupole magnets with integrated sextupoles, non-zero dispersion in the straight sections and a common girder for all magnets in the same cell. The lattice of the MAX II ring has been characterised in order to evaluate these solutions, to assist in MAX II operatio

In the Nordic Reference Interval Project 2000 (NORIP) serum, Li-heparin plasma and EDTA buffy coat were collected at 102 laboratories in 5 Nordic countries from healthy individuals aged 18 years or more and evenly distributed for laboratory, gender and age. Multiple aliquots of these samples from each of about 3000 persons are now stored at the Nordic Reference Interval Project Bio-bank and Databa

Abstract in Norwegian Artikkelen presenterer de skandinaviske helgenene Theodor væringen og sønnen Johannes, Russlands protomartyrer med utgangspunkt i russiske kilder, men utifra et skandinavisk perspektiv. Den presenterer likeens den hellige Anna (Ingegerd) av Novgorod med utgangspunkt i både russiske og norrøne kilder.

The ability of a nematode-trapping fungus to establish in field soil is an important characteristic when considering its use as a biological control agent. The outgrowth of the nematode-trapping fungus Arthrobotrys superba from wood was recorded by labelling the fungus with [14C]3-O-methylglucose and [32P]orthophosphoric acid and by using the soil sprinkling method. The fungus reached a distance o

10 patients with chronic hepatitis C virus (HCV) infection who previously had responded temporarily to 9 months interferon alpha-2b treatment with normalization of ALT levels during treatment but later relapse were given a second 6-month treatment course. All patients were positive for anti-HCV by a second generation ELISA confirmed by second generation RIBA and positive for HCV RNA in serum befor

Popular Abstract in Swedish Parkinsons sjukdom är den näst mest vanliga neurodegenerativa sjukdomen och den drabbar 2% av befolkningen över 65 år. Sjukdomen kännetecknas av en gradvis ökad förlust av dopaminproducerande nervceller. Symtomen tilltar successivt och leder framförallt till allvarliga fördröjningar i rörelsemönstret. Dessvärre, när de första symptomen väl upptäcks, så har redan 50% av Parkinson's disease (PD) is the second most common neurodegenerative disease and affects 2% of the population over 65 years of age. The disease is characterized by the progressive loss of dopaminergic neurons. Over time, symptoms increase and, in particular, lead to a dramatic slowness of movements. Unfortunately, when the fi rst symptoms are discovered, more than 50% of the dopaminergic neurons a

In this study an economic analysis of the purification of integrated solid waste treatment facility leachates through a willow-coppice (Salix) vegetation filter in southern Sweden was carried out. Calculations were based on the use of two computer models that were initially used in estimating a pump-and-pipe irrigation system for a 36-ha willow-coppice plantation to purify an average annual quanti

The three-dimensional structure of Bruton's agammaloglobulinemia tyrosine kinase (Btk) SH2 domain was modeled based on v-Src. Btk SH2 is presumably very related to the other SH2 structures consisting of two beta-sheets surrounded by two alpha-helices, with a well conserved hydrophobic core and phoshotyrosyl peptide binding site. The model was used to predict the recognition sequence of the target
