L’étude des cultes isiaques dans la péninsule Ibérique donne à connaître une série de documents qui représentent un pied sous sa forme réelle ou gravé sur des stèles votives. Se pose alors la question de l’origine de ce symbole. Apparenté aux divinités égyptiennes, il est synonyme de richesse et d’abondance dans la religion pharaonique. À partir de la vallée du Nil, les deux modèles se sont diffusés dans le monde méditerranéen et ils ont atteint l’Hispanie au IIe siècle en passant sans doute par le continent africain. Sans aucune référence dans la littérature antique, l’enquête menée autour de ces représentations et de leurs différentes déclinaisons n’autorise pas à leur attribuer une seule signification. Les pieds de Sérapis comme les stèles dédiées à Isis incarnent le plus souvent l’épiphanie divine, mais ils peuvent également être considérés comme de simples témoignages de dévotion. Lorsque les empreintes de pieds correspondent à celles de la déesse et que les stèles sont situées devant l’entrée du temple, elles pourraient faire référence à un rituel d’accueil. [less ▲]

The continued downscaling of the metal-oxide semiconductor (MOS) transistor for sub-22 nm logic circuits with boosted performance will require the introduction of new channel materials with carrier mobility higher than that of Si, such as Ge for pMOS. The use of III-V compounds for nMOS devices poses however additional challenges related to the hetero-epitaxial growth of a polar semiconductor on a non-polar surface. Furthermore, these high-mobility materials have to be fabricated on large-area Si substrates, in the perspective of application in a standard low-cost very-large-scale integration scheme. In this work, we report on the successful growth of GaAs on 200 mm Si wafers by means of metal-organic vapor deposition using a modified Crius Close-Coupled Showerhead system from AIXTRON AG. We used Si (100) wafers with off-axis orientation (6° miscut towards <111>) in order to avoid the formation of anti-phase domains which lead to Ga-Ga and As-As bonds at their boundaries that have strong detrimental effects on the electrical conduction. In our approach, based on Ge virtual substrates with low threading dislocation (TD) density, the lattice mismatch between Si and GaAs is accommodated and, thus, no additional TD is introduced in the deposited III-V film. Our results show that smooth GaAs layers can be epitaxially grown on large-area Si substrates with high wafer-scale thickness uniformity. The excellent quality of the deposited GaAs was confirmed by photoluminescence and electron microscopy. Our process also demonstrates very high selectivity on patterned wafers with SiO2 mask and enabled the fabrication of capacitor structures using an integration process flow very similar to standard high volume Si manufacturing lines. The capacitance-voltage characteristics were similar to the ones obtained on a bulk GaAs substrate, and showed extremely tight within-wafer and wafer-to-wafer distributions as is standard to Si manufacturing.

Climatic variations happen at all time scales and since the origins of these variations are usually of very complex nature, climatic signals are indeed chaotic data. The identification of the cycles induced by the natural climatic variability is therefore a knotty problem, yet the knowing of these cycles is crucial to better understand and explain the climate (with interests for weather forecasting and climate change projections). Due to the non-stationary nature of the climatic time series, the simplest Fourier-based methods are inefficient for such applications (see e.g. Titchmarsh (1948)). This maybe explains why so few systematic spectral studies have been performed on the numerous datasets allowing to describe some aspects of the climate variability (e.g. climatic indices, temperature data). However, some recent studies (e.g. Matyasovszky (2009); Paluš & Novotná (2006)) show the existence of multi-year cycles in some specific climatic data. This shows that the emergence of new tools issued from signal analysis allows to extract sharper information from time series. Here, we use a wavelet-based methodology to detect cycles in air-surface temperatures obtained from worldwide weather stations, NCEP/NCAR reanalysis data, climatic indices and some paleoclimatic data. This technique reveals the existence of universal rhythms associated with the periods of 30 and 43 months. However, these cycles do not affect the temperature of the globe uniformly. The regions under the influence of the AO/NAO indices are influenced by a 30 months period cycle, while the areas related to the ENSO index are affected by a 43 months period cycle; as expected, the corresponding indices display the same cycle. We next show that the observed periods are statistically relevant. Finally, we consider some mechanisms that could induce such cycles. This chapter is based on the results obtained in Mabille & Nicolay (2009); Nicolay et al. (2009; 2010). [less ▲]

The aim of this study was to investigate the influence of isoenergetic substitution between the three energy delivering macronutrients in pre-starter diets on performance and intermediary nutrient metabolism in broiler chickens. From hatch until 5 days of age, 600 chicks, collected during peak of hatch, were fed one of the three experimental pre-starter diets with isoenergetic (13 MJ metabolisable energy/kg) substitutions between fat (43 vs. 108 g/kg), protein (126 vs. 240 g/kg) and carbohydrates (391 vs. 510 g/kg). After 5 days, commercial grower and finisher diets were provided. Pre-starter composition influenced body weight until slaughter age, although not statistically verifiable. Broilers fed the low protein (LP) pre-starter had the lowest body weight in relation to chickens on the low carbohydrate or low fat pre-starter diet. After hatch, chicks on the LP pre-starter diet were able to use the residual yolk sac more rapidly to fulfil their protein requirement, which is reflected in small intestine and liver development. Also, plasma metabolite levels were influenced mostly by the LP pre-starter, indicating that the main focus for the requirements of newly hatched chicks should be on proteins. Furthermore, optimal nutrition during the first day's post-hatch should take into account the contribution of the yolk. [less ▲]

The Family Apperception Test (FAT) is a projective assessment procedure based on the family system theory. FAT allows the subjects’ affects and feelings about their family to be assessed. The original version and its French translation removed some of the conceptual and psychometric limitations of previous projective tests and family assessment procedures but several questions remained. The current study proposes several modifications to the conceptual background, administration, coding procedure, and standardization of the FAT, which considerably improve its psychometric properties. Data were collected on 168 typical and clinical children in the French-speaking part of Belgium. The results provide significant evidence for inter- and intra-assessor reliability; the factorial analysis and the internal consistency of the revised version were good; the FAT enabled us to discriminate between typical children and those in the clinical sample. The discussion focuses on the interest and limits of the quantitative coding procedure, based on several categories conceptualized as risk versus protective factors. The FAT is characterized by a complementary approach—both quantitative and qualitative—to the children and their families. [less ▲]

Cette contribution questionne nos pratiques d’évaluation du comportement chez le jeune enfant. Les données concernant le comportement de 118 enfants ont été collectées par questionnaires et observation auprès de leurs parents, leurs enseignants et les cliniciens lors du recrutement et après 12 mois. Les résultats indiquent une variabilité importante entre les jugements évaluatifs des différents informateurs et un impact négatif de cette variabilité sur le développement ultérieur de l’enfant. Les résultats plaident en faveur d’une procédure multi-informateurs et multiméthodes dont les implications sont discutées sur le plan clinique. [less ▲]

Nonadherence to pharmacological treatment in osteoporosis is a well-recognized problem. As in other chronic diseases, adherence to osteoporosis treatment is poor, resulting in enormous burden on patients and healthcare resources. Most importantly, low adherence rates consistently result in increased rates of fractures. However, it seems that efforts to evaluate and improve rates of both compliance and persistence are increasing. The extension of dosing intervals may be an element, among others, allowing improvements in therapeutic adherence. Improved patient education, enhancing healthcare provider-patients interaction, taking into account patient's preferences and involving them in treatment decisions may improve adherence. [less ▲]
