Fabrication, packaging and experimental results on the calibration of metal-semiconductor-metal (MSM) photodetectors made on diamond are reported. LYRA (Lyrnan-alpha RAdiometer onboard PROBA-2) will use diamond detectors for the first time in space for a solar physics instrument. A set of measurement campaigns was designed to obtain the XUV-to-VIS responsivity of the devices and other characterizations. The measurements of responsivity in EUV and VUV spectral ranges (40-240 nm) have been carried out by the Physkalisch-Technische Bundesanstalt (PTB) in Germany at the electron storage ring BESSY II. The longer wavelength range from 210 to 1127 nm was measured with monochromatic light by using a Xe-lamp at IMO-IMOMEC. The diamond detectors exhibit a photoresponse which lie in the 35-65 mA/W range at 200 nm (corresponding to an external quantum efficiency of 20-40%) and indicate a visible rejection ratio (200-500 nm) higher than four orders of magnitude.

Magnesium (Mg) therapy is often proposed against stress and to correct asthenia. Thus our aim has been to review the role of Mg, the mechanisms of its homeostasis before detailing the clinical presentations and etiologies of hypo- and hypermagnesemia and their exploration. Hypomagnesemia frequently occurs but is clinically rarely recognized without biological serum ionic determinations because causing atypical signs miming those of other ion deficiencies. Hypermagnesemia is uncommon but often occurs in the presence of renal insufficiency especially with excess of Mg administration. [less ▲]

This chapter summarizes the various NMR experiments that were applied to probe the main stereochemical features of polymers prepared by ring-opening metathesis polymerization (ROMP) of 2,3-dicarboalkoxynorbornadienes and 2,3-dicarboalkoxynorbornenes catalyzed by the dichloro ruthenium arene dimer (RuCl2(p-cymene))2 in the presence of trimethylsilyldiazomethane (TMSD). Direct spectroscopic methods based on the examination of cross-coupling peaks in polymers derived from optically active monomers (1H COSY NMR) and indirect methods based on the analysis of the hydrogenated derivatives of unsaturated parent polyolefins (1H and 13C NMR) led to the same conclusion. They both showed that high trans, highly isotactic polymers were formed using the ruthenium-arene catalyst precursor. [less ▲]

Evidence has recently accumulated indicating that aromatase activity in the preoptic area is modulated in parallel by both slow (hours to days) genomic and rapid (minutes to hours) non-genomic mechanisms. We review here these two types of control mechanisms and their potential contribution to various aspects of brain physiology in quail. High levels of aromatase mRNA, protein and activity (AA) are present in the preoptic area of this species where the transcription of aromatase is controlled mainly by steroids. Estrogens acting in synergy with androgens play a key role in this control and both androgen and estrogen receptors (ER; alpha and beta subtypes) are present in the preoptic area even if they are not necessarily co-localized in the same cells as aromatase. Steroids have more pronounced effects on aromatase transcription in males than in females and this sex difference could be caused, in part, by a sexually differentiated expression of the steroid receptor coactivator 1 in this area. The changes in aromatase concentration presumably control seasonal variations as well as sex differences in brain estrogen production. Aromatase activity in hypothalamic homogenates is also rapidly (within minutes) down-regulated by exposure to conditions that enhance protein phosphorylation such as the presence of high concentrations of calcium, magnesium and ATP. Similarly, pharmacological manipulations such as treatment with thapsigargin or stimulation of various neurotransmitter receptors (alpha-amino-3-hydroxy-methyl-4-isoxazole propionic acid (AMPA), kainate, and N-methyl-d-aspartate (NMDA)) leading to enhanced intracellular calcium concentrations depress within minutes the aromatase activity measured in quail preoptic explants. The effects of receptor stimulation are presumably direct: electrophysiological data confirm the presence of these receptors in the membrane of aromatase-expressing cells. Inhibitors of protein kinases interfere with these processes andWestern blotting experiments on brain aromatase purified by immunoprecipitation confirm that the phosphorylations regulating aromatase activity directly affect the enzyme rather than another regulatory protein. Accordingly, several phosphorylation consensus sites are present on the deduced amino acid sequence of the recently cloned quail aromatase. Fast changes in the local availability of estrogens in the brain can thus be caused by aromatase phosphorylation so that estrogen could rapidly regulate neuronal physiology and behavior. The rapid as well as slower processes of local estrogen production in the brain thus match well with the genomic and non-genomic actions of steroids in the brain. These two processes potentially provide sufficient temporal variation in the bio-availability of estrogens to support the entire range of established effects for this steroid. [less ▲]

A satisfactory prediction of the settlements of hyperstatic structures is becoming more and more important in their design and construction. In this paper, the problems related to the behaviour of a group of piles and to the quality of the drilled piles of the canal-bridge of Houdeng (Belgium) are analysed in a non conventional fashion, based on a finite element analysis, thanks to sufficient experimental data. The influence of an imperfectly cleaned excavation bottom and of the destructuration of the bottom rocks caused by the drilling of the piles is investigated. A particular attention is also given to the behaviour of a group of piles. [less ▲]

Coatings are designed to protect concrete against environmental aggression. Water is one of the aggressive parameters able to deteriorate the concrete structure. The objectives of this paper are to present the effects of water (i) during application of coating on the concrete substrate and (ii) pull-off test. Semi-permanent moisty state produced by absorption from the uncoated face, total immersion or diffusion of water from the back face of the substrate are analysed. Water vapour diffusion and influence of hydrophobic treatment are also investigated. A classification based on increasing influence of the tests and application conditions on adhesion is proposed and clearly points out the negative effect of capillary action from the uncoated face.

There is a complex functional organization of the central auditory system from the brainstem to primary and associative auditory cortices. Functional neuroimaging has been used to visualize and confirm the spatial distribution of brain activation in temporal areas for the processing of simple acoustic stimuli. Brain activity is much more complex for words, and different networks can be recruited when phonological, lexical and semantic levels of processing are engaged. [less ▲]

Several compounds of the NaMn(Fe1-xInx)(2)(PO4)(3) solid solution were synthesized by solid state reaction in air; pure alluaudite-like compounds were obtained for x = 0.00 to 1.00. X-ray Rietveld refinements indicate the presence of Na+ at the A1 and A2' sites, Mn2+ at the M1 site, and Fe2+, Fe3+, and In3+ at the M2 site. The presence of small amounts of In3+ at the M I site, and Mn2+ at the M2 site, indicates a partially disordered distribution between these cations. A good correlation was also established between the M1-M2 bond distance and the beta angle of the alluaudite-like compounds. The disordered distribution of Fe2+, Fe3+, and In3+ at the M2 site is confirmed by the broadness of the infrared absorption bands. The Mossbauer spectra, measured between 90 and 295 K, were analyzed in terms of a model that takes into account the next-nearest neighbor interactions around the M2 crystallographic site. In all cases these spectra reveal the unexpected presence of small amounts of Fe2+ at the M2 site, an amount that decreases as the In3+ content increases. The Fe2+ and Fe3+ isomer shifts are typical of the alluaudite structure and vary with temperature, as expected from a second-order Doppler shift. The derived iron vibrating masses and Mossbauer lattice temperatures are within the expected range of values for iron cations in an octahedral environment. The Fe2+ and Fe3+ quadrupole splittings are also typical of the alluaudite structure and the temperature dependence of the Fe2+ quadrupole splitting was fit with the model of Ingalls (1964), which yielded a ground state orbital splitting of ca. 380 to 570 cm(-1) for the Fe2+ sites.
