BACKGROUND AND PURPOSE: Preeclampsia is a major obstetric problem of unknown etiology. The fact that removal of the placenta is the only cure for preeclampsia, has led to the well-established hypothesis, that the placenta is central in the etiology. Gene profiling and proteomics studies have suggested oxidative stress caused by reperfusion and free oxygen radicals as a potential pathophysiological

Nasal speech sounds occur in most of the languages of the world. Two goals concerning nasalisation in speech were pursued in the studies presented in this volume. One deals with the development and testing of a method for recording nasal vibration with an accelerometer microphone attached to the outer part of the nose, and analysing the signal with the help of a wide band spectrogram. The other ai

A new detector is presented which finds changes in the repolarization phase (ST-T complex) of the cardiac cycle. It operates by applying a detection algorithm to the filtered root mean square (rms) series of differences between the beat segment (ST segment or ST-T complex) and an average pattern segment. The detector has been validated using the European ST-T database, which contains ST-T complex

Background: Today, practically all computed tomography (CT) systems are delivered with automatic exposure control (AEC) systems operating with tube current modulation in three dimensions. Each of these systems has different specifications and operates somewhat differently. Purpose: To evaluate AEC systems from four different CT scanner manufacturers: General Electric (GE), Philips, Siemens, and To

Psoriasis is a common, chronic disease and in one-third of the patients it begins during the first 2 decades of life. The burdens of psoriasis are many, and some can be assessed with quality of life questionnaires. The aim was to investigate the impact of childhood psoriasis on quality of life in children and their parents and to correlate certain clinical findings with quality of life. Forty-five

The article provides an overview of ongoing research and key characteristics of Cognitive Semiotics, an emerging field dedicated to the transdiciplinary study of meaning, involving above all researchers from semiotics, linguistics, developmental and comparative psychology and philosophy. The combination of the following features distinguishes it from other synthetic approaches: (a) integration of

To characterise geographical distribution and time trends of chronic kidney disease (CKD) mortality in the context of the epidemic of Mesoamerican nephropathy (MeN), likely related to occupational heat stress and other, unknown, factors.

This paper presents a hysteretic (sliding mode) control IC for a buck DC/DC converter for use as an envelope tracking power supply to increase the efficiency of an RF power amplifier. The IC integrates a high-bandwidth error amplifier, a comparator with hysteresis, and a high-side driver for an external N-channel power MOSFET. The total control loop delay using the implemented IC is 35ns, this is

Pilgrimage is an important element of Christianity right from the start, being rooted in the Jewish religion. Pilgrimage to sites in the Holy Land develops strongly in the fourth century as the sites are made accessible and are adorned with sanctuaries by the Emperor. The Cross of Christ becomes an important object of devotion to pilgrims, but the story of its discovery is considered by many schol
