Forte de 107 numéros publiés de 1928 à 1939, la revue L’Equerre se définit comme le lieu de l’énoncé d’une position militante et engagée défendant la mise en place d’une architecture et d’un urbanisme résolument novateur. Elle publie les travaux des principaux représentants de l’architecture moderne belge et internationale (V. Bourgeois, L.H. De Koninck, Le Corbusier, G. Terragni, A. Sartoris...). La place faite à l’actualité internationale et la position de certains de ses membres au sein d’organes de représentation de l’architecture internationale (CIAM) font de cette revue un acte manifeste dans le mouvement de l’architecture de la seconde génération moderniste.

The main aim of this paper was to present some feeding recommendations, which, when applied on the farm, would increase nitrogen use by bovines and to give information as to how the effects of the nitrogen produced can be reduced. Ruminants have the ability to digest structural carbohydrates and to produce meat and milk proteins for human consumption. At the animal cells level, amino acids are essential for biological functions, mainly involving their maintenance and production. These amino acids are supplied by the intestinal digestion of microbial protein and feed protein that escapes microbial degradation in the rumen. Today, the efficiency of nitrogen utilization is typically low and highly variable in ruminants. Nitrogen excretion by ruminants mainly depends on the level of nitrogen intake and of the animal's productivity. Optimal N utilization may be achieved through an understanding of the key mechanisms involved in the control of N digestion and metabolism. These include the efficiency of N capture in the rumen and the protein degradation according to the type of diet and forage, the control of the rumen microorganisms involved in protein degradation and the proper formulation of the diet, avoiding feeding excess protein in relation to requirements. The dependence on energy supply in transferring feed nitrogen into milk and meat protein is strong both at the rumen and the cell levels of ruminants. The rumen metabolism is identified as the single most important factor contributing to the low level of efficient use of nitrogen in ruminants and partially depends on practical farming operations.

L’équilibre forêt/grande faune reste une des préoccupations majeures des gestionnaires forestiers européens. Une réflexion a été entammée concernant la mise en place de dispositifs susceptibles de fournir une information sur la pression subie par la régénération naturelle en peuplements feuillus. Cette réflexion à concerné la mise en place d’inventaires par échantillonnage ou l’installation d’enclos-exclos. Les résultats obtenus ne se sont pas révélés concluants dans le cas des inventaires et sont en devenir pour les enclos-exclos. L’objectif vise à produire des outils opérationnels permettant de quantifier la pression du grand gibier sur la régénération en forêt feuillue. Cet objectif se traduit par l’étude simultanée de 2 approches complémentaires : - Proposer une méthode de mise en place et de suivi de dispositifs enclos-exclos ; - Réévaluer la mise au point d’un protocole d’inventaire par échantillonnage pour caractériser la pression du grand gibier sur la régénération en forêt feuillue. Pour tester les possibilités offertes par ces 2 approches, nous avons choisi de réaliser nos premières investigations sur 2 sites pilotes caractérisés par des pressions de gibier contrastées. Les conditions écologiques des deux sites peuvent être considerées comme équivalentes. [less ▲]

A comparison of two English texts written by Lewis Carroll, one (Alice in Wonderland), also translated into Esperanto, the other (Through the Looking Glass) are discussed in order to observe whether natural and artificial languages significantly differ from each other. One dimensional time series like signals are constructed using only word frequencies (FFS) or word lengths (LTS). The data is studied through (i) a Zipf method for sorting out correlations in the FFS and (ii) a Grassberger-Procaccia (GP) technique based method for finding correlations in LTS. The methods correspond to an equilibrium and a dynamic approach respectively to human texts features. There are quantitative statistical differences between the original English text and its Esperanto translation, but the qualitative differences are very minutes. However different power laws are observed with characteristic exponents for the ranking properties, and the phase space attractor dimensionality. The Zipf exponent can take values much less than unity (similar to 0.50 or 0.30) depending on how a sentence is defined. This variety in exponents can be conjectured to be an intrinsic measure of the book style or purpose, rather than the language or author vocabulary richness, since a similar exponent is obtained whatever the text. Moreover the attractor dimension r is a simple function of the so called phase space dimension n, i.e., r = n(lambda), with lambda = 0.79. Such an exponent could also be conjectured to be a measure of the author style versatility, - here well preserved in the translation. (C) 2008 Elsevier B.V. All rights reserved. [less ▲]

We have combined first-principles calculations and high-pressure experiments to study pressure-induced phase transitions in silicon nitride (Si 3N 4). Within the quasi-harmonic approximation, we predict that the α phase is always metastable relative to the β phase over a wide pressure-temperature range. Our lattice vibration calculations indicate that there are two significant and competing phonon-softening mechanisms in the β-Si 3N 4, while phonon softening in the α-Si 3N 4 is rather moderate. When the previously observed equilibrium high-pressure and high-temperature β → γ transition is bypassed at room temperature (RT) due to kinetic reasons, the β phase is predicted to undergo a first-order structural transformation to a denser P6̄ phase above 39 GPa. The estimated enthalpy barrier height is less than 70 meV/atom, which suggests that the transition is kinetically possible around RT. This predicted new high-pressure metastable phase should be classified as a "postphenacite" phase. Our high-pressure x-ray diffraction experiment confirms this predicted RT phase transition around 34 GPa. No similar RT phase transition is predicted for α-Si 3N 4. Furthermore, we discuss the differences in the pressure dependencies of phonon modes among the α, β, and γ phases and the consequences on their thermal properties. We attribute the phonon modes with negative Grüneisen ratios in the α and β phases as the cause of the predicted negative thermal expansion coefficients (TECs) at low temperatures in these two phases, and predict no negative TECs in the γ phase. © 2011 American Physical Society.

Two High Speed Steels (HSS) have been studied both having chemical compositions closed one to another. Both HSS grades exhibited similar matrix/carbides microstructure in the industrial as-cast conditions, except for M7C3 eutectic carbides only observed in one grade and fine pearlite only found in the other grade. Equilibrium diagrams were obtained from Thermodynamical simulations to enhanced predicted phase transformations whereas Differential Thermal Analysis was performed on both alloys in order to determine their crystallization behaviour in non equilibrium conditions. Light microscopy and Electron microscopy associated with microprobe analyses were done to characterize the microstructure of both alloys. Thermal treatments with related bulk hardness assessments were carried out to enhance conditions for pearlite formation at the end of the casting route. In continuous cooling conditions obtained from DTA simulations, the matrix of both as-cast HSS grades is composed of eutectic carbides, martensite and retained austenite, these phases exhibiting similar chemical compositions. The introduction of an intermediate isothermal stage in the solid state within the DTA cooling sequence leads to the formation of a fine pearlite phase mainly located in the vicinity of M2C eutectic carbides on one HSS grade. The origin of this fine pearlite is discussed in this paper. [less ▲]

For a single crystal of YNi(2)B(2)C superconductor, the equilibrium magnetization M in the square basal Plane has been studied experimentally as a function of temperature and magnetic field. While the magnetization M(H) deviates from conventional London predictions, a recent extension of London theory (to include effects of nonlocal electrodynamics) describes the experiments accurately. The resulting superconductive parameters are well behaved. These results are compared with corresponding findings for the case with M perpendicular to the basal plane. [less ▲]

This paper presents a procedure for computing approximate solution of bending Kirchhoff plate with an equilibrium finite element model. The accuracy of the equilibrium approach is evaluated through the concept of error estimator. Especially, a dual analysis by finite elements which leads to lower and upper bounds of the exact solution is presented in numerical examples. [less ▲]
