Pulsed wave (PW) Doppler ultrasound systems are commonly used to examine blood flow dynamics and the technique plays a very important role in numerous diagnostic applications. Commonly, narrow-band PW systems estimate the blood velocity using an autocorrelation-based estimator. Herein, we examine a recently proposed hybrid frequency estimator, and via extensive numerical simulations using simulate

Findings from a pilot study on the distribution, function and phonetic realization of the filler EH in interviews from SweDia2000 interviews are presented. The results show that EH occurs almost exclusively after function words at the beginning of constituents. The phonetic realization of EH was seen to be of three basic forms: a middle-high vowel (e.g. [e], [ɛ], [ə]), a vowel+nasal (e.g. [ɛm], [ə

Following the recent developments in supply chain management and environmental policy integration, it became evident that for successfully addressing the environmental challenges a holistic approach is necessary. After identifying a lack of sufficient information on the environmental performance and the uptake of the respective policy measures from food supply chain perspective, a research has bee

We screened 29 strains of Neisseria gonorrhoeae and found 16/21 strains that resisted killing by normal human serum and 0/8 serum sensitive strains that bound the complement regulator, C4b-binding protein (C4bp). Microbial surfacebound C4bp demonstrated cofactor activity. We constructed gonococcal strains with hybrid porin (Por) molecules derived from each of the major serogroups (Por1A and Por1B)

A survey of parity-changing E1 transitions has been pursued in N>~Z nuclei near 56Ni using data from an EUROBALL experiment. Linear polarization measurements have been combined with angular correlations of coincident gamma rays to determine the electromagnetic character of numerous transitions. The impact of the results on shell-model parametrizations is briefly discussed.

Tardigrades are well known for their capacity to enter an anhydrobiotic state, and remain ametabolic for several years. Yet the evolutionary background, and the forces of natural selection that act on anhydrobiotic capacity have remained unexplored. In this paper, I review the basic problem of anhydrobiosis and the phenotypic traits that may be the main targets of natural selection for improved an

Objective: To investigate the association between human herpesviruses and multiple sclerosis ( MS), as well as between measles virus and MS. Methods: The authors identified prospectively collected serum samples from 73 MS cases and retrospective sera from 161 MS cases in two population-based serum bank registers. Analyses of IgG antibody responses in cases and matched referents were performed for

Exact and approximate quantum numbers of the cranked Nilsson-Strutinsky (CNS) formalism are exploited to calculate excited bands in fixed configurations with the energy of the individual bands minimized with respect to deformation for all spin values. The formalism is applied to Cu-59, where all bands which appear important in the decay out of the superdeformed band are calculated.

It is difficult to determine whether transient folding intermediates have a cooperative (or first-order) folding transition without measuring their rates of formation directly. An intermediate I could be formed by a second-order transition from a denatured state D that is progressively changed into I as conditions are changed. We have not been able to monitor the rate of formation of the folding i

Abstract in French Dans cet article j’aborderai, suite à ma thèse de doctorat, la problématique autour du récit en constellation en conversation exolingue. On appelle le récit en constellation le récit qu’un seul et même locuteur produit à plusieurs reprises en présence de locuteurs différents. Ce type de récit s’est avéré intéressant de plusieurs points de vue, notamment en ce qui concerne l’orig

Delar av den svenska träbyggnadsindustrin har stora möjligheter att utveckla det industriella byggandet. Villor har lång tradition av att prefabriceras i fabriker för senare transport och montage på byggplats. Volymbyggnadsteknik där prefabriceringen även innefattar ytskikt och installationer har ökat prefabriceringsgraden avsevärt. Fortfarande är dock tillverkningen hantverksbetonad och genomförs

The aim of this study was to assess the rate of clinical progression to early and late stages of human immunodeficiency virus-2 (HIV-2) infection. CD4 cell counts and other potential prognostic markers for disease progression were also evaluated. In January 1990 an open prospective cohort of police officers in Guinea-Bissau was initiated with yearly serological and clinical follow-up. Follow-up en
