OBJECTIVES: Under physiological conditions the blood flow velocity waveform in the umbilical vein (UV) has an even non-pulsating pattern. Pulsations in the UV have been described in human fetuses exposed to chronic hypoxia and heart failure. Current techniques for fetal surveillance during labor and delivery involve a risk of both over- and underestimation of fetal hypoxia. We aimed to examine whe

Le présent travail veut s’inscrire dans une tradition de linguistique appliquée dont l’ambition consiste à allier théorie et empirisme. Lorsque l’on tâche de combiner deux domaines, on pourrait espérer qu’ils s’avèrent mutuellement enrichis ; Dans le meilleur des cas, la théorie permettrait non seulement l’élaboration d’hypothèses et de questions pertinentes sur les données mises en place par la d

The aim of this article is to propose a method for creating a more coherent concept of norms – and to deliver a tentative and open suggestion on how to define norms in a way that might fit into the context of Sociology of Law (further on shortened, SoL). The idea is that the norm concept can be chiselled out through ontological analysis, and that this analysis can be conducted in a way that allow

For MIMO systems, we introduce two novel architectures that significantly reduce the required number of expensive RF chains and still perform as well as a conventional full complexity solution for many cases of interest. We combine RF pre-processing - based solely on channel statistics and not instantaneous channel state - with selection and corresponding baseband signal processing. For a system w

To examine the ascending projections from the headache-related trigeminocervical complex in rats, biotinylated dextran amine (BDA) was injected into the ventrolateral dorsal horn of segments C1 and C2, a region previously demonstrated to receive input from sensory nerves in cranial blood vessels. Following injections into laminae I-II, BDA-labelled terminations were found bilaterally in several nu

Anti-JAHK, an antibody directed toward a low-incidence antigen in the Rh system, was detected during routine antibody identification in a male donor who had no history of transfusion. Examples of anti-JAHK have been found in sera containing multiple antibodies to low-incidence antigens. The first report of anti-JAHK was in 1995 and described the association of the JAHK antigen with the rG haplotyp

A phase-shifting PLL frequency offsetter has been developed for use in the comparison of near-equal frequencies by phase-time recordings. The input frequency is shifted by means of a phase-shifting phase-locked loop. Time-linear phase shifting is simply obtained by inserting an RC link in the loop. Continuous operation is obtained by polarity switching of the capacitor and the phase detector at su

Historically, lethal exsanguinations and severe infections have been two major causes of maternal death. Gene mutations that lower the risk of profuse hemorrhage or severe infections would give a survival advantage. A single mutation of coagulation factor V, known as FV Leiden (FVL), can be such a beneficial mutation. FVL is common among Caucasians and today confers an increased risk of thromboemb

Discussion of the why and how of keeping up the agnostic (not atheistic) character of academic exegesis, and the effects of having an insider or outsider perspective (bias) on the matters explored in this discipline.

Abstract in French En Suède comme dans d’autres pays européns, les pratiques de l’organisation de l’espace connaissent actuellement des transformations radicales, dues au développement des technologies (principalement dans les infrastructures, les transports et la communication), àla mondialisation de l’éonomie et àl’intération accrue du pays dans l’Union europénne. Le regard portésur les possibil
