The effect of evaporative drying on the pore size of two series of hybrid silica gels is investigated by combining beam bending on the gels and mercury porosimetry on the aerogels and xerogels with transmission electron microscopy on the xerogels. It is shown that the shrinkage of the pores during drying is different in the two series: in one series the pores shrink proportionally to their volume, in the other the pores collapse until they all reach the same size. The experimental data enable us to discuss the relation between these two different behaviours and the different morphology of the two series of gels. [less ▲]

Purpose of review Patients in a vegetative or minimally conscious state continue to pose problems in terms of diagnosis, prognosis and treatment. Despite recent waves of international media attention following Terri Schiavo's death and the 'miracle recovery' of Terry Wallis, research efforts aimed at increasing our knowledge about brain function in these conditions remain scarce and must address a series of difficulties, including financial and ethical barriers. Here we review current possibilities and limitations of clinical and para-clinical assessment of chronic disorders of consciousness. Recent findings During the past year the field has witnessed publication of significant, yet isolated, case reports in top-ranking journals, including Science and Nature. Such milestone reports and other impressive recent technological advances in the study of vegetative and minimally conscious patients reveal enthralling areas of science that must find their way to clinical medical reality. Summary Consciousness is a subjective experience whose study has remained within the purview of philosophy for millennia. That has finally changed, and empirical evidence from functional neuroimaging offers a genuine glimpse at a solution to the infamous mind-body conundrum. New technological and scientific advances offer the neurological community unique ways to improve our understanding and management of vegetative and minimally conscious patients. [less ▲]

Like many other deltas, Egypt is particularly vulnerable to the effects of global warming. A relative rise in sea-level of 1 m would submerge much of the delta region within 30 km of the coast during the next 100 years. Rising sea levels would have significant long-term impacts on physical, biological and socio-economic conditions of the Nile Delta. These include the damage and destruction of buildings near beaches, erosion of beaches, salt-water intrusion, and flooding more than 1,200 km2 of Egypt’s Delta Coastline. [less ▲]

This paper reports the hydrothermal synthesis and crystal structure refinement of diiron(II) phosphate hydroxide, Fe-2(II)(PO4)(OH), obtained at 1063 K and 2.5 GPa. This phosphate is the synthetic analogue of the mineral wolfeite, and has a crystal structure topologically identical to those of minerals of the triplite-triploidite group. The complex framework contains edge-and corner-sharing FeO4(OH) and FeO4(OH)(2) polyhedra, linked via corner-sharing to the PO4 tetrahedra (average P-O distances are between 1.537 and 1.544 angstrom). Four five-coordinated Fe sites are at the centers of distorted trigonal bipyramids (average Fe-O distances are between 2.070 and 2.105 angstrom), whereas the coordination environments of the remaining Fe sites are distorted octahedra (average Fe-O distances are between 2.146 and 2.180 angstrom). The Fe-O distances are similar to those observed in natural Mg-rich wolfeite, except for two Fe-O bond distances, which are significantly longer in synthetic Fe-2(2+) (PO4)(OH). [less ▲]

This paper studies some extensions to the decentralized attitude synchronization of identical rigid bodies. Considering fully actuated Euler equations, the communication links between the rigid bodies are limited and the available information is restricted to relative orientations and angular velocities. In particular, no leader nor external reference dictates the swarm's behavior. The control laws are derived using two classical approaches of nonlinear control - tracking and energy shaping. This leads to a comparison of two corresponding methods which are currently considered for distributed synchronization - consensus and stabilization of mechanical systems with symmetries. [less ▲]

BACKGROUND: Levonorgestrel-releasing intrauterine system (LNG-IUS), although inserted to reduce heavy menstruation, causes irregular early transient bleeding. The objective of the study was to document quantitative changes in endometrial vessels of short- (< or =3 months) and long-term (> or =12 months) LNG users. The area, density and maturation of endometrial vessels were quantified in 19 endometrial biopsies of women with LNG-IUS and in 10 normally ovulating patients during mid-luteal phase. METHODS: Vessel maturation was evaluated by double immunostaining using anti-von Willebrand factor (endothelial cell marker) and anti-alpha Smooth Muscle Actin (vascular smooth muscle cells) antibodies. Vessel area, number and density were quantified with a novel computer-assisted image analysis system. RESULTS: Endometrium exposed to LNG-IUS for 1-3 months displayed a 11.5-fold increase in small naked vessel number. The partially mature vessel (alphaSMA partially positive) number increased six times. After long-term LNG-IUS treatment, the immature and partially mature vessel number remained four times higher than in the control group. Vessel area and density also increased dramatically in a time-dependent pattern with LNG-IUS use. CONCLUSIONS: Levonorgestrel affects blood vessel number, area, density and maturation in a time-dependent pattern that may explain the early transient increase in breakthrough bleeding with the LNG-IUS.

On the legal aspect, the new European Directive on ElectroMagnetic Compatibility 2004/108/EC concerns also large machines. The conformity assessment procedure in that case should be clarified and which standards should be applied and how. On a technical point of view, the special situation to characterise the EMC behaviour of large machines implies that current procedures are complex and very expensive, and in some cases even not possible. Adapted measuring methodologies and procedures are needed. As a response to this situation and within the European R&D Frameworks, the TEMCA2 project aimed to develop new and adapted methodologies for the assessment of EMC related to this type of industrial large machinery. The present paper describes the legal aspect for large machines and shows the objectives and the results of the European TEMCA2 project. [less ▲]

Les programmes de surveillance liés à la mise en oeuvre de la DCE sont coordonnés par le Ministère de l’Ecologie et de l’Aménagement durable (MEDAD) et dans chaque bassin hydrographique ce sont les Agences de l’eau qui, avec l’Etat, prennent en charge l’application, la mise en oeuvre de ces réseaux. Sur la façade méditerranéenne, Ifremer a assuré pour le compte du Schéma Directeur des Données sur l’Eau la maîtrise d’ouvrage de la première campagne du contrôle de surveillance, en coordonnant l’ensemble de l’acquisition des données et de leur synthèse en collaboration avec de nombreux partenaires : Universités, bureaux d’études, structures locales de gestion et services de l’Etat. La mobilisation des différents acteurs autour d’un objectif commun a permis de faire face à la pluridisciplinarité et à la complexité des aspects logistiques de ce programme. Les résultats de cette première campagne du contrôle de surveillance (2006) permettent d’ores et déjà d’avoir une bonne vision d’ensemble de la qualité des eaux littorales à l’échelle du district. Ils confortent les évaluations faites « à dire d’expert » lors de l’état des lieux du district avec des informations nouvelles concernant plus particulièrement la biologie, notamment le benthos de substrat meuble. En eaux côtières, les eaux sont de bonne qualité. En eau de transition, essentiellement lagunaires, il existe une plus grande hétérogénéité des résultats avec des paramètres déclassant relevant plutôt de la biologie, mais sur un nombre important d’indicateurs.

Hormone replacement therapy (HRT) remains the most effective treatment for menopausal symptom relief, and may provide cardiovascular benefits in younger women initiating treatment soon after menopause. However, large surveys indicate that many symptomatic women refuse or discontinue HRT prematurely owing to fear of weight gain. A continuous combined HRT containing 17beta-estradiol (E(2)) 1 mg plus drospirenone (DRSP) 2 mg is effective in relieving menopausal symptoms and preventing postmenopausal osteoporosis. DRSP is a unique synthetic progestogen with a pharmacological profile similar to that of natural progesterone, including antialdosterone activity, a property not exhibited by other synthetic progestogens. DRSP can therefore reduce estrogen-related sodium and water retention in postmenopausal women receiving HRT via the renin-angiotensin-aldosterone system, which regulates sodium and water balance. This may translate into weight benefits. Pooled data from two placebo-controlled clinical trials (n = 333) indicated statistically significant weight loss of -1.5 kg at 6 and 12 months in postmenopausal women receiving E(2)/DRSP vs. placebo (p < 0.001). In a third randomized controlled trial (n = 1147), women receiving E(2)/DRSP maintained or lost weight, whereas weight increases were observed in women receiving E(2) monotherapy (p < 0.0125). E(2)/DRSP could help maintain or even slightly decrease body weight during treatment, potentially improving HRT acceptance and compliance. [less ▲]
