Perenniporiella chaquenia sp. nov. is described from Argentina. New records of P. pendula and P. micropora are discussed. A key to Perenniporiella species is presented. Preliminary phylogenetic relationships of Perenniporiella are inferred from parsimony and Bayesian analysis of a combined set of DNA sequence data (nuclear ribosomal partial LSU and ITS). It demonstrated that Perenniporiella forms a well resolved monophyletic clade distantly related to Perenniporia s.s. It also clearly showed that within Perenniporia as usually conceived other morphologically homogeneous group of taxa, such as the P. ochroleuca or P. vicina alliances, form well resolved clades, which could be recognized as distinct genera. The differentiation of the hyphal system and the basidiospores morphology are outlined as critical features for the definition of genera in the Perenniporia complex. [less ▲]

In 1999, the large surface-rupturing earth- quakes of Izmit and Duzce completed a 60-year cycle that included a westward migration of nine consecutive large earthquake failures ([50 km surface rupture), which started with the 1939 Erzincan earthquake in eastern Turkey. In this study, we focused on seismic cycles and seismic risk predictability along the North Anatolian Fault (NAF). Toward the west end of the NAF (26°E–32°E, i.e. Bolu), large earthquake fre- quency is measured from either historic earthquake catalogs, or geologic records from isolated outcrops and marine sediment cores from the Marmara Sea. In comparison, the eastern part of the NAF zone (32°E– 42°E) is less well documented by palaeo-seismologic archives. Thus, the sediment records of lake basins located on the eastern NAF zone constitute a unique opportunity for testing a new palaeo-seismologic approach. To this end, we used a diverse array of complementary methods involving: (1) a 600-km transect of fault-related lakes, (2) sedimentologic observations on cores from six lakes, and (3) a comparison between records of catastrophic sediment transfers in lakes (i.e. radionuclide chronomarkers and erosion tracers) and historic earthquake reports. Our study indicates that lakes along the NAF are sensitive geologic recorders of large surface-rupturing earth- quakes (surface-wave magnitude (Ms) C 6.9); smaller intensities are not recorded. The most responsive lake systems exhibit increases in sediment accumulation by a factor of [40 for a [3-m strike-slip displacement (Ms C 7). However, based on results from the 1939 Erzincan earthquake (Ms = 7.8) chronostratigraphic marker, large surface-rupturing earthquakes are detected only by certain lake records and not by others. Matching multiple lake records along the NAF pro- vides information both on the location of a surface rupture of a paleo-earthquake as well as its magnitude. Finally, the shallow lake basins along the NAF could potentially document cycles of large seismic events for at least the late Holocene. [less ▲]

Mesoporous anatase thin films were prepared by the evaporation-induced self-assembly process. This paper reports a study of the influence of several physical parameters on the long-range ordering of the mesopores. A preliminary study was done to set the best humidity conditions during dip-coating and ageing of the films. The withdrawal speed, already known to modify the thickness of the deposited film, was shown to exert a strong influence on the percentage of porosity. This was studied by step profilometry combined with Rutherford backscattered spectrometry (RBS). In parallel, small angle X-ray scattering (SAXS), X-ray diffraction (XRD), transmission electron microscopy (TEM) and RBS were used to tune the precise thermal treatment applied to the so-obtained films, in order to preserve the porous mesostructure and promote the nanocrystallization of anatase TiO2.

ABSTRACT Objective: Markov models are increasingly used in economic evaluations of treatments for osteoporosis. Most of the existing evaluations are cohort-based Markov models missing comprehensive memory management and versatility. In this article, we describe and validate an original Markov microsimulation model to accurately assess the cost-effectiveness of prevention and treatment of osteoporosis. Methods: We developed a Markov microsimulation model with a lifetime horizon and a direct health-care cost perspective. The patient history was recorded and was used in calculations of transition probabilities, utilities, and costs. To test the internal consistency of the model, we carried out an example calculation for alendronate therapy. Then, external consistency was investigated by comparing absolute lifetime risk of fracture estimates with epidemiologic data. Results: For women at age 70 years, with a twofold increase in the fracture risk of the average population, the costs per quality-adjusted life-year gained for alendronate therapy versus no treatment were estimated at Euro 9105 and Euro 15,325, respectively, under full and realistic adherence assumptions. All the sensitivity analyses in terms of model parameters and modeling assumptions were coherent with expected conclusions and absolute lifetime risk of fracture estimates were within the range of previous estimates, which confirmed both internal and external consistency of the model. Conclusion: Microsimulation models present some major advantages over cohort-based models, increasing the reliability of the results and being largely compatible with the existing state of the art, evidence-based literature. The developed model appears to be a valid model for use in economic evaluations in osteoporosis. [less ▲]

An approach is introduced for studying the adsorption and recognition mechanisms of biomolecules, without using any markers. We show for the first time, that the Sum Frequency Generation spectroscopy performed in the Total Internal Reflection (TIR-SFG) geometry, combined with a regular close-packed array of gold nanoparticles allows to probe with a high sensitivity the changes in conformation and orientation induced by the recognition process of avidin by biocytin. This approach represents a new platform with potential use in biosensors, diagnostics and bioactive layers. [less ▲]

Le poète liégeois François Jacqmin (1929-1992) est l’auteur d’une œuvre qui étonne par sa densité et par sa profondeur – d’autant que, chez lui, ces deux caractéristiques prennent la forme de vers simples, limpides, lumineux. Aussi, le premier mouvement de la critique consiste-t-il à chercher, sous la simplicité, la profondeur enfouie, au point de faire du poète un penseur. Le penseur n’est pas oublié dans ce volume, qui constitue la première monographie universitaire consacrée à l’auteur du Livre de la neige, mais c’est surtout le poète qui a retenu l’attention. Ou, du moins, la pensée est-elle envisagée ici dans la nuance de sa matérialité poétique. François Jacqmin est lu dans ses poèmes. [less ▲]

Vernalization is known to promote flowering in Arabidopsis thaliana by inhibiting the expression of a strong repressor: FLOWERING LOCUS C (FLC). The recent cloning of an FLC-LIKE gene in sugar beet (Beta vulgaris; BvFL1) and – here – in root chicory (Cichorium intybus; CiFL1) suggests the conservation of FLC biological function during evolution of eudicots. Hence physiological questions that remain difficult to address in Arabidopsis can be studied in other species. We investigated the correlation between CiFL1 expression and plant-age dependent responsiveness to vernalization. We also studied the effect of post-vernalization growing temperature, which can stabilize or erase the vernalized state. [less ▲]

The present study was aimed to assess the effect of different levels of red worm (Perionyx excavatus) supplemented to the diet on growth performance and meat quality of broilers. An experiment was conducted on broilers (Ho x Luong Phuong) of 4 - 10 weeks old according to a completely randomized design with one unsupplemented group (control) and three supplemented groups corresponding to 3 worm levels in the diet, viz. 1%, 1.5%, and 2% on a dry matter basis. Results showed that the 2% worm supplemented group had the highest growth rate, higher than the control group (1925.3 kg/head vs 1822.6 kg/head at the age of 10 weeks) with P <0.05. Chicken in the supplemented groups had lower FCR. The dressing percentage, and leg meat in the 2% worm supplemented group were higher than those of the control group. The different levels of red worm supplementation did not significantly affect meat quality (pH, color, the rate of dehydration after storage and processing). [less ▲]

N-Heterocyclic carbenes (NHCs) form stable zwitterionic adducts with a range of heteroallenes, ketenes, and allenes. Although the first representatives of this class of inner salts were first investigated as far back as the 1960s, they have enjoyed a sustained interest from the chemical community over the years. Depending on the nature of their anionic moiety, NHC betaines display a very broad palette of reactivities and have found applications in various fields of organic synthesis and catalysis. In this Microreview, the synthesis, properties, and reactivity of NHC betaines are surveyed. The NHCs under consideration include ylidenes derived from imidazole, benzimidazole, imidazoline, thiazole, or triazole, and the heteroallenes investigated so far are carbon dioxide, carbon disulfide, isocyanates, isothiocyanates, and their selenium analogues. A historical background is provided for each type of adduct under consideration, but emphasis is placed mainly on developments that have appeared in the literature within the past few years.

For many years, the Strasbourg Manuscript was believed to be the oldest German-language source for the study of Northern European painting techniques. Unfortunately, the manuscript was lost in the 1870 fire at the Strasbourg Library, and the text only survives in a 19th-century transcription made for Eastlake (1847). Studies such as those of Ploss and more recently those of Oltrogge have already highlighted the existence of texts with very similar contents, grouping them under the name of the ‘Strasbourg family’. Since these studies, a clearly defined corpus of manuscripts has been established as belonging to this family. This paper shows the different degrees of connection between the texts and presents some suggestions concerning their compilation process. The possibility of collating different versions of an identical text and cross-checking recipes can also be exploited to learn more about the ways in which recipe books were compiled, and to provide information concerning their use and function.

La communication proposée offre l'analyse des conclusions d'une expérience de terminologie juridique bilingue menées au travers d'une double publication : un dictionnaire juridique bilingue (français - espagnol) de la Responsabilité civile et un ouvrage de synthèse sur la Terminologie et le Droit . Dans la ligne du titre du colloque, le Droit occupe un lieu significatif, puisque le problème d'intercompréhension qu'il pose consiste à établir les points d'équivalence possibles entre deux "mondes" (deux droits) par définition étrangers l'un à l'autre. Cette affirmation se fonde sur une analyse des domaines du savoir humain, orientée vers la démonstration de ce que le Droit entre, avec peu d'autres domaines, dans la catégorie de ceux qui n'ont pas de référent universel, ce qui, aux dires de certains, rend sa traduction prétendument impossible. Ensuite, la communication détaillera l'analyse des équivalences (et degrés de celles-ci) dont fait montre le dictionnaire cités ci-dessus, selon qu'il établit des catégories d'équivalence totale, d'équivalence partielle ou d'absence de toute équivalence possible. Cette analyse, avec tous les exemples illustratifs disponibles, cède alors le pas à plusieurs réflexions théoriques et conduit à proposer enfin une théorie de la traduction juridique :"qu'est-ce que traduire en droit?".

Periodic dielectric multilayer structures can generate interferential colours from optically transparent basic materials. Their iridescence property, i.e. the change of colour with the illumination or viewing angle, is exploited in the industry to produce structurally coloured coatings and paints. Magnetron sputtering is an efficient technique for producing multilayer films owing to its ability to deposit films on large surfaces with excellent uniformity and reproducibility in both the film thickness and composition. Based on a theoretical model of the optical response, we investigated the iridescence tuning range of the technologically important SiO2/TiO2 material system. Radically different iridescent behaviours were predicted theoretically and demonstrated experimentally by selecting appropriate combinations of period and layer thickness ratio. [less ▲]

Since the discovery of the first exoplanet around 51 Pegasi, the study of planetary systems receives an increasing attention, with the development and test of more and more detection techniques. Among the direct detection techniques, interferometry is one of the most promising for the near future. It already provides the required angular resolution, but the dynamic range needs to be improved. The detection and characterisation of extrasolar planets is one of the main science cases of the 2nd generation VLTI Spectro-Imager instrument (VSI). The goal of this work is to study the feasibility of obtaining near-infrared spectra of bright extrasolar giant planets (EGP) with VSI. [less ▲]
