Aurora and Kosmos grades are HSS alloys belonging to the complex Fe-Cr-C-X system, where X is a strong carbide former element of the V, Mo or W type. Both alloys were metallurgically characterised prior to their comparison. Metallurgical analyses involved phases identification and carbides quantification by using Scanning Electron Microscopy and Energy Dispersive X rays. Differential Thermal Analysis was performed to allow a better understanding of the solidification sequence of studied alloys while mechanical tests performed were compressive at room temperature and bulk hardness at usual service temperatures. An attempt was made in order to connect experimental results to the good behaviour in operation of Aurora grade. In fact Aurora grade appeared to exhibit strong metallurgical differences when compared to Kosmos grade, especially as concern in nature and amount of carbides. [less ▲]

The paper explores the concept of the 'Center of the Main Interests' which plays a key role under the European Insolvency Regulation to allocation jurisdiction in international insolvency proceedings. The paper reviews the case law of courts of EU Member States and the first cases decided by the European Court of Justice in order to draw some preliminary lessons on how to identify where the Center of the Main Interests of the debtor lies.

The self-formation phenomenon of hierarchy with multiple-scaled porosity is reported. The structures of various chemical compositions, such as ZrO2, TiO2, Al2O3, Y2O3, Nb2O5, Ta2O5 ZrO2-SiO2, ZrO2-TiO2, ZrO2-Y2O3, aluminosilicates, aluminophosphates, silicoaluminophosphates, metallophosphates, are made of macrochannels (0.5-5 μm in diameter) with mesoporous or microporous walls. The hierarchically porous structures are prepared by just controlling the hydrolysis and polycondensation rates of the pre-selected inorganic sources. The textural, structural as well as morphological properties of each material are carefully studied by using a large series of techniques, such as XRD, NMR, TEM, SEM, N2 adsorption-desorption, Hg porosimetry, optical microscopy. On the basis of these multimodal porous structures, a new concept "Hierarchical Catalysis" has been proposed. This new concept can allow the realisation of a multiple steps reaction in one single catalyst in a cascade way without any separation processes. © 2007 Elsevier B.V. All rights reserved. [less ▲]

Modern electrophysiological studies in animals show that the spectrum of neural oscillations encoding relevant information is broader than previously thought and that many diverse areas are engaged for very simple tasks. However, EEG-based brain-computer interfaces (BCI) still employ as control modality relatively slow brain rhythms or features derived from preselected frequencies and scalp locations. Here, we describe the strategy and the algorithms we have developed for the analysis of electrophysiological data and demonstrate their capacity to lead to faster accurate decisions based on linear classifiers. To illustrate this strategy, we analyzed two typical BCI tasks. (1) Mu-rhythm control of a cursor movement by a paraplegic patient. For this data, we show that although the patient received extensive training in mu-rhythm control, valuable information about movement imagination is present on the untrained high-frequency rhythms. This is the first demonstration of the importance of high-frequency rhythms in imagined limb movements. (2) Self-paced finger tapping task in three healthy subjects including the data set used in the BCI-2003 competition. We show that by selecting electrodes and frequency ranges based on their discriminative power, the classification rates can be systematically improved with respect to results published thus far.

For a given numeration system, the successor function maps the representation of an integer n onto the representation of its successor n+1. In a general setting, the successor function maps the n-th word of a genealogically ordered language L onto the (n+1)-th word of L. We show that, if the ratio of the number of elements of length n + 1 over the number of elements of length n of the language has a limit b> 1, then the amortized cost of the successor function is equal to b/(b − 1). From this, we deduce the value of the amortized cost for several classes of numeration systems (integer base systems, canonical numeration systems associated with a Parry number, abstract numeration systems built on a rational language, and rational base numeration systems).

Osteoarthritis (OA), the most common form of arthritis, is a public health problem throughout the world. Several entities have been carefully investigated for the symptomatic and structural management of OA. This review evaluates published studies of the effect of glucosamine salts and chondroitin sulfate preparations on the progression of knee or hip OA. Despite multiple double-blind, controlled clinical trials of the use of glucosamine and chondroitin sulfate in OA, controversy regarding the efficacy of these agents with respect to symptomatic improvement remains. Several potential confounders, including placebo response, use of prescription medicines versus over-the-counter pills or food supplements, or use of glucosamine sulfate versus glucosamine hydrochloride, may have relevance when attempting to interpret the seemingly contradictory results of different clinical trials. The National Institutes of Health-sponsored GAIT (Glucosamine/chondroitin Arthritis Intervention Trial) compared placebo, glucosamine hydrochloride, chondroitin sulfate, a combination of glucosamine and chondroitin sulfate and celecoxib in a parallel, blinded 6-month multicentre study of patients with knee OA. This trial showed that glucosamine hydrochloride and chondroitin sulfate alone or in combination did not reduce pain effectively in the overall group of patients with OA of the knee. However, exploratory analyses suggest that the combination of glucosamine hydrochloride and chondroitin sulfate may be effective in the subgroup of patients with moderate-to-severe knee pain. For decades, the traditional pharmacological management of OA has been mainly symptomatic. However, in recent years, several randomised controlled studies have assessed the structure-modifying effect of glucosamine sulfate and chondroitin sulfate using plain radiography to measure joint space narrowing over years. There is some evidence to suggest a structure-modifying effect of glucosamine sulfate and chondroitin sulfate. On the basis of the results of recent randomised controlled trials and meta-analyses, we can conclude that glucosamine sulfate (but not glucosamine hydrochloride) and chondroitin sulfate have small-to-moderate symptomatic efficacy in OA, although this is still debated. With respect to the structure-modifying effect, there is compelling evidence that glucosamine sulfate and chondroitin sulfate may interfere with progression of OA. [less ▲]

In Moldavia, three sequences serve as the basis for the chronological context for Gravettian (and Epigravettian) occupations. Two technological phases have been identified, showing independent development, homogenous in both technological and typological attributes. The Gravettian is characterized by large retouched blades, followed by shouldered points (29,500-23,000 BP), succeeded by the Early Epigravettian (13,500-11,000 BP). [less ▲]

BACKGROUND: The most predominant beta2-integrin lymphocyte function-associated antigen-1 (LFA-1, CD11a/CD18, alphaLbeta2), expressed on all leukocytes, is essential for many adhesive functions of the immune system. Interestingly, RTX toxin-producing bacteria specifically target this leukocyte beta2-integrin which exacerbates lesions and disease development. RESULTS: This study reports the sequencing of the wild boar beta2-integrin CD11a and CD18 cDNAs. Predicted CD11a and CD18 subunits share all the main structural characteristics of their mammalian homologues, with a larger interspecies conservation for the CD18 than the CD11a. Besides these strong overall similarities, wild boar and domestic pig LFA-1 differ by 2 (CD18) and 1 or 3 (CD11a) substitutions, of which one is located in the crucial I-domain (CD11a, E168D). CONCLUSION: As most wild boars are seropositive to the RTX toxin-producing bacterium Actinobacillus pleuropneumoniae and because they have sustained continuous natural selection, future studies addressing the functional impact of these polymorphisms could bring interesting new information on the physiopathology of Actinobacillus pleuropneumoniae-associated pneumonia in domestic pigs.
