This papers deals with the emergency control of Load Tap Changers (LTCs) to face low transmission voltages or voltage instability situations. The proposed simple control logic consists in reverting the tap movements once the voltage at a monitored transmission bus falls below some threshold. A deadband on this voltage allows the system to settle down in between the normal and reverse logic modes. In order to control a large number of LTCs, the latter are divided into clusters, each with its own monitored voltage. The paper also considers the control of two levels of LTCs in cascade, where proper coordination is required between the two levels. The proposed scheme has been tested on a detailed EHV-HV-MV planning model of the Western region of the French transmission system operated by RTE. Long-term time responses to major disturbances are shown to illustrate the performance of the proposed scheme. [less ▲]

This paper describes the on-line Voltage Security Assessment environment developed within the framework of the EU-sponsored OMASES project, as well as its application to the Greek Interconnected Power System. The heart of all computations is a fast time-domain method. Security is analyzed with respect to power transfers in critical corridors or power consumption in load areas. Results take on the form of either precontingency secure operation limits, or post-contingency loadability limits, together with various diagnosis tips. Typical results obtained during the test phase of the project are reported. [less ▲]

The paper presents the efforts and results of a large consortium of European Industries, Research Centers and Universities involved in an EU research project named OMASES in the field of Power System Dynamic Security Assessment (DSA). The overall structure of an on-line DSA tool including TSA – Transient Stability Assessment, VSA – Voltage Stability Assessment, TS – Training Simulator and MS – Market Simulator is reported. Some basic assumptions and methodological aspects of the tool are presented considering its possible use within actual or future Energy Management Systems under the new electric market environment. Scenarios set up for the validation phase and results are reported with reference to the Italian test facility. [less ▲]

La quantification de la vitesse de biosynthèse de la sérotonine ainsi que l'étude in vivo chez l'homme sont, du fait de l'implication cruciale des neurones sérotoninergiques dans de nombreuses fonctions et pathologies cérébrales, des domaines d'études fondamentaux pour lesquels la TEP constitue un outil de choix. Ces différentes expérimentations peuvent être conduites suivant deux optiques: (i) emploi d'un traceur capable de suivre la chaîne métabolique du tryptophane conduisant à la sérotonine tout en évitant les autres voies métaboliques. (ii) utilisation d'un inhibiteur de la tryptophane hydroxylase (TPOH), enzyme limitante du processus. [less ▲]

The study is made in the frame of a follow-up monitoring of all landfill sites in Wallonia, initiated by the Ministry of Environment and managed by ISSeP. The research group applied a field inspection technique based on the perception of a panel of experts sniffing the air around the region of interest and trying to delineate the odour plume. In a second step, the recorded meteorological data are entered into an atmospheric dispersion model and the odour emission rate of the facility is adjusted until the predicted odour impact zone fits about exactly the one which is measured in the field. The present report concerns the site of Froidchapelle. It presents also a discussion about the possible errors of the used method. [less ▲]

The aim of the project was to perform a feasibility study for possible development of freight intermodal transport links between Belgium and Bulgaria, between North and Black sea and vice versa, taking inland waterways (iww) transport mode as basic one. The key focus is assessment of benefits in adopting an intermodal manner for transferring cargo instead of the single transport mode currently in use. The paper comprises short description of trans-continental infrastructure between Belgium and Bulgaria and its abilities to serve for different transport alternatives, definitions and choice of appropriate scenarios for realising predicted cargo flows, as well as cost calculations. Comparative analysis of the considered transport alternatives has been made. The most important results obtained are transport cost evaluation and benefit assessment for investigated transport scenarios [less ▲]

We have gathered and analyzed 1493 high-quality multicolor Geneva photometric data taken over 21 years of the B3V star HD 129929. We detect six frequencies, among which appear the effects of rotational splitting with a spacing of ~0.0121 cycles per day, which implies that the star rotates very slowly. A nonadiabatic analysis of the oscillations allows us to constrain the metallicity of the star to Z â [0.017,0.022], which agrees with a similar range derived from spectroscopic data. We provide evidence for the occurrence of core convective overshooting in the star, with alpha[SUB]ov[/SUB] = 0.10 +/- 0.05, and we rule out rigid rotation. [less ▲]

Great scourge of poor countries, malaria is the most important tropical parasitic disease. It is responsible for a large number of deaths in concerned countries and represents a real danger for travellers going to endemic regions. So, prophylactic measures are essential. On the one hand protective measures against mosquito bites, by wearing covering clothes, by using repellents and bed net (eventually impregnated with insecticide) will be useful. On the other hand, chemoprophylaxis is most often necessary, adapted to the possibility of chloroquine resistant P. falciparum, to the length or conditions of travel, and to the traveller's antecedents and age. Special concern about pregnant woman is necessary, due to potential severity of malaria. Chemoprophylaxis needs to be continued after coming back, for a duration depending on the drug used. Unfortunately, no prophylaxis is 100% effective, and the appearance of fever during the travel or two to three months after return requires medical advice. In some circumstances, it is necessary to prescribe a stand-by emergency treatment, if no quick medical advice is possible. [less ▲]

Chronic renal failure is an unrecognised disease, with an insidious and rather silent development, for which the general practitioners are too often passive. This review would like to insist on the detection of people at risk or with early abnormalities, on the optimal guidelines to slowdown the evolution to more severe and irreversible stages, on the prevention of uremic and cardiovascular complications and on the preparation to end stage renal treatments.
