We discuss the first results of our ongoing optical spectroscopic monitoring campaign of the two O-type stars 9 Sgr and HD 168112. Both objects display a non-thermal radio emission and were considered as single stars. Based on a large set of high-resolution spectra, we find that 9 Sgr is clearly an eccentric SB2 binary with an orbital period of several years. On the other hand, no evidence for radial velocity variations attributable to binary motion is found in our spectra of HD 168112. [less ▲]

Today the smoker carries a risk of mortality 70% higher compared to the nonsmoker. In Belgium active smoking is indisputably the most important cause of avoidable death. In 2004 it appears that 27% of the belgian population was smoking. This review describes the comorbidity associated with active tobacco consumption and defines the concepts of dependence and smoking cessation. It also identifies the three factors which determine the success of smoking cessation, i.e. the degree of nicotinic dependence, the presence of anxio-depressive disorders and the importance of the motivation to the stop.

The concept of death has evolved as technology has progressed. This has forced medicine and society to redefine its ancient cardiorespiratory centred diagnosis to a neurocentric diagnosis of death. The apparent consensus about the definition of death has not yet appeased all controversy. Ethical, moral and religious concerns continue to surface and include a prevailing malaise about possible expansions of the definition of death to encompass the vegetative state or about the feared bias of formulating criteria so as to facilitate organ transplantation.

Oral steroids can interrupt bouts of cluster headache (CH) attacks, but recurrence is frequent and may lead to steroid-dependency. Suboccipital steroid injection may be an effective 'single shot' alternative, but no placebo-controlled trial is available. The aim of our study was to assess in a double-blind placebo-controlled trial the preventative effect on CH attacks of an ipsilateral steroid injection in the region of the greater occipital nerve. Sixteen episodic (ECH) and seven chronic (CCH) CH outpatients were included. ECH patients were in a new bout since no more than I week. After a one-week run-in period, patients were allocated by randomization to the placebo or verurn arms and received on the side of attacks a suboccipital injection of a mixture of long- and rapid-acting betamethasone (n=13; Verum-group) or physiological saline (n=10; Plac-group). Acute treatment was allowed at any time, additional preventative therapy if attacks persisted after I week. Three investigators performed the injections, while four others, blinded to group allocation, followed the patients. Follow-up visits were after I and 4 weeks, whereafter patients were followed routinely. Eleven Verum-group patients (3 CCH) (85%) became attack-free in the first week after the injection compared to none in the Plac-group (P=0.0001). Among them eight remained attack-free for 4 weeks (P=0.0026). Remission lasted between 4 and 26 months in five patients. A single suboccipital steroid injection completely suppresses attacks in more than 80% of CH patients. This effect is maintained for at least 4 weeks in the majority of them.

A comparison was performed of the tetrapyrrole transformations that occur upon irradiation of epicotyl or leaves of dark-grown Pisum sativum L. (var. Zsuzsi, Hungary). High performance liquid chromatography analysis after continuous or flash-irradiation showed that the biosynthetic pathway from protochlorophyllide (Pchlide) to chlorophyll (Chl) a was markedly slowed down at the step of the reduction of geranylgeranyl(gg)-Chl to dihydrogeranylgeranyl (dhgg)-Chl in epicotyls, whereas phytyl-Chl was synthesized in leaves subjected to the same light treatments. Quantitative pigment analysis during continuous irradiations of different intensities also showed that significant Pchlide photodestruction occurred in epicotyls even under weak light. When both Pchlide and chlorophyllide and/or chlorophylls were present in epicotyls, Pchlide photodestruction was faster under 630-nm light than under 670-nm light, which indicates that this process is most efficiently promoted by Pchlide excitation. Pre-incubation of epicotyl segments with 10 mM ascorbate partly alleviated pigment photodestruction in white light. It is concluded that formation of photoactive Pchlide-Pchlide oxidoreductase complexes is important to prevent fast pigment photooxidation after Pchlide accumulation in the dark. [less ▲]

La succession des crises alimentaires a poussé les consommateurs européens à exiger toujours plus de garantie quant à la sécurité de l’alimentation destinée à l’homme et aux animaux d’élevage. La législation européenne a, en conséquence, évolué rapidement et le niveau d’exigence s’est fortement accru, le principe de base étant pour le producteur, l’importateur et le distributeur de pouvoir prouver aux autorités compétentes que toutes les précautions ont été prises, qu’une traçabilité des produits entrant dans la chaîne alimentaire existe et que, en cas de problème avéré ou suspecté, une procédure de notification, de rappel ou de retrait a été prévue et mise en place. Pour les producteurs ACP, ces évolutions les ont conduit à devoir modifier dans l’urgence leurs pratiques. La réussite de la mise en conformité et la mise en pratique dans les entreprises d’une politique de management de la qualité a exigé un effort important de formation non seulement au niveau des managers, des cadres et du personnel des entreprises, mais aussi au niveau de tous les acteurs qui gravitent autour de la filière « fruits et légumes d’exportation ». Le PIP a développé un dispositif de formation basé sur la capitalisation de compétences chez les acteurs locaux : prestataires de services et formateurs ACP, cadres techniques intermédiaires, responsables de laboratoire, agents de l’état chargés du contrôle, etc. Commencées depuis 2003, les actions du PIP en faveur des entreprises ACP concernent à présent plus de 80% du tonnage des fruits et légumes frais (hors bananes) exportés vers l’Union européenne.

Positive trait information is typically better recalled than negative trait information when encoded in reference to the self, but not when encoded in reference to someone else or when processed for general meaning. This study examined whether this influence of affective meaning is modulated by retrieval conditions. Participants encoded positive and negative trait adjectives in reference to themselves or to a celebrity. They were then presented with either a free-recall task (Experiment 1) or a recognition memory task (Experiment 2). Positive adjectives were better recalled than negative adjectives, but only when they were encoded in reference to the self. In contrast, encoding condition and valence did not interact in the recognition memory task. Taken together, these findings suggest that the difference in memory between positive and negative self-referent information is due, at least in part, to a control exerted on memory retrieval.

This paper presents an experimental analysis of the influence of the liquid rheology on the gas flow pattern in a bubble column reactor. Aqueous solutions of xanthan are selected as an example of non-Newtonian shear thinning fluid. Averaged gas holdup is determined by two experimental techniques: parietal pressure probes and electrical resistance tomography (ERT). ERT is also used to provide 2D images of the gas phase distribution in a column cross-section. Bubble size distributions are evaluated by a gas disengagement technique using the parietal pressure probes. All these techniques clearly show the gas flow pattern is different in Newtonian and non-Newtonian fluids. Gas holdup values decrease when increasing the liquid viscosity and reach a minimum or a plateau. Homogeneous flow regime, observed in water at low gas velocities, tends to disappear when viscosity increases. This evolution is visualized by a much less isotropic distribution of the gas phase within cross-section of the column and by the appearance of much larger bubbles due to an increased coalescence phenomenon.

The crystal structure of cyproterone (systematic name: 6-chloro-1,2-dihydro-17-hydroxy-30H-cyclopropa[a]pregna-1,4,6- triene-3,20-dione), C22H27ClO3, is compared with cyproterone acetate, a potent anti-androgen steroid. The two compounds adopt a similar conformation, except for the cyclopropyl ring attached to the cyclohexenone ring (ring A). Cyproterone further adopts a crystal packing distinct from that of the acetate form. These differences result from hydrogen bonding between the free hydroxy group and the carbonyl group of ring A.

Based on airlift configuration, a novel circulating jet-loop submerged membrane bioreactor (JLMBR) adapted to ammonium partial oxidation has been developed. Membrane technology and combined air and water forced circulation are adopted to obtain a high biomass retention time and to achieve a separate control of mixing and aeration. This study is intended to determine how gas-liquid mass transfer is affected by operating conditions. In a first approximation, liquid was assumed to be perfectly mixed. A classical non-steady state clean water test, known as the "gas out-gas in" method, was used to determine the gas-liquid mass transfer coefficient k(L)a. Air and recirculated liquid superficial velocities were gradually increased from 0.013 to 0.019m s(-1) and 0.0056 to 0.011 m s(-1), respectively. Subsequently, the gas-liquid mass transfer coefficient kLa varied from 0.01 to 0.02 s(-1). It appears to be influenced by the combined action of air and recirculated liquid flowrates in the range 0.72-1.03N m(3) h(-1) and 0.30-0.58 m(3) h(-1), respectively, for air and liquid. Correlations are proposed to describe this double influence. Experiments were performed on tap water and a culture medium used for the autotrophic growth of nitrifying bacteria, respectively. Oxygen transfer appeared to be not significantly affected by the mineral salt (0.48 g 1(-1)) encountered in this medium. (c) 2005 Elsevier Ltd. All rights reserved. [less ▲]

A factorial design statistical analysis has been conducted in order to obtain the optimum conditions in the solid state sintering process of barium zirconate bulk materials, optimum with respect to density, closed and open porosities. The optimized heat treatment permits to sinter a 99% dense barium zirconate sample at 1650 degrees C during only 2 h. When the temperature is higher than 1650 degrees C or when the heating time is longer than 2 h, a decrease in density is observed. (c) 2004 Elsevier Ltd. All rights reserved. [less ▲]
