At the microscale, classical bearings such as ball bearings, sliding bearings and other pivots may be difficult to manufacture. Among all possible solutions to replace them, the notch hinge seems to be very attractive through its many advantages. The major limitation is on the rotation angle. This paper presents a new simplified analytical model for the prediction of the maximum angular displacement and the angular stiffness of a notch hinge. To validate our model, an experimental set-up has been developed. Finally, the results are compared to other theories. [less ▲]

This article approaches the way in which General Franco's regime depicted the Marxist philosophy, so much so from the educational programme of the regime, as from the different treatment it experienced from the various sectors of the regime, such as the Church, the "Falange" or the legal and political system. This way of approach towards the characterization of Marxism, following the dictator's own evolution, goes as far as the mythology of the great criminals of the nation ('the Jewish- Masonic conspiracy') until the so called economic-social research [less ▲]

Les élections de 2006 en République démocratique du Congo marquaient la fin d'une étape dans le processus de reconstruction de l'Etat après les guerres qui ont marqué la région de l'Afrique des Grands Lacs depuis les années 1990. La dispersion des votes sur de nombreux partis peu structurés lors des élections législatives, provinciales et sénatoriales marque le paysage politique congolais. L'élection présidentielle a montré une opposition entre deux grands candidats, l'un, Joseph Kabila, mieux soutenu à l'Est et l'autre, Jean-Pierre Bemba, à l'Ouest du pays. [less ▲]

Accurate models of hydraulic motors and their interaction with flexible structures are needed to design motion control and vibration suppression schemes for hydraulically actuated flexible robots. The modeller of such a system faces significant challenges including capturing the dynamics of the actuator, integrating the actuator model into the system model, incorporating distributed parameter elements into the system model, determining any unknown model parameters, and creating a model that is useful for control design. This paper presents a model that overcomes all of these challenges. A transfer matrix model of a hydraulic actuator interacting with a flexible robot is developed. This model is integrated into a system model for a flexible robot. The model captures the interaction between the actuator and the structure and has been experimentally validated. [less ▲]

Central Vietnam is composed of two contrasting topographic areas parallel to the coastline: mountains in the West and lowlands in the East where most of the population is concentrated. Sandy soils are largely dominant in the cultivated area in this narrow strip along the sea. Typical constraints of these soils are chemical infertility and acidity, excessive drainage capacity, low organic matter content, associated with particular climate limitations: heavy rain, floods and droughts during certain periods. In the paper, we described a detailed survey among 145 households in villages from the 4 districts of the coastal area of the Thua Thien Hue Province. Existing practices and the socio-economic situation are evaluated and selected pilot farmers are involved in the research of optimal practices. Soil samples (300) and organic matter samples (95) are collected during this survey. The partners of the research include the Hue University of Agriculture and Forestry, the National Institute for Soils and Fertilizers in Vietnam, the Faculty of Agricultural Sciences of Gembloux, and the Catholic University of Louvain in Belgium.

Published data related to javelin throwers remain poorly documented. The objectives of this study were therefore to compare isokinetic strength profile of the shoulder rotator muscles between javelin throwers and sedentary persons and to correlate isokinetic data with different field performance parameters. Eleven male javelin throwers and ten sedentary subjects participated in the study. Shoulder internal (IRs) and external rotators (ERs) were isokinetically assessed at 60, 240 and 400 degrees/s in concentric and 60 degrees/s in eccentric exertions. Subjects also performed throwing tests successively using a javelin and a ball (both of 800 g mass). Side to side comparison in the throwers group revealed a dominance effect in the concentric mode for the IRs at all speeds, and for the ERs at 240 degrees/s. Sedentary subjects showed a dominance effect for the IRs at 60 degrees/s and 240 degrees/s. Simple isokinetic concentric-concentric ratios and mixed velocity DCRs (eccentric60/concentric240) of the dominant shoulder were significantly lower in comparison to the non-dominant side values, in the throwers population. Only the simple ratio at 400 degrees/s and the mixed ratio were significantly lower in the sedentary subjects (dominant versus non dominant side). With respect to the dominant shoulder, no significant difference was noted between the groups the peak torque was bodyweight normalized. However, throwers showed a significant reduction of the DCR when compared to the control group. In addition, throwers exhibited moderate to strong correlations (0.61 <= r <= 0.89) between IRs and ERs strength and either the javelin throw test or the personal throwing record. For the sedentary subjects the javelin throw test was correlated only with the IRs concentric strength at 240 degrees/s. In conclusion, javelin throwers showed a significantly reduced mixed ratio in comparison with a control group, even though body weight normalized peak torques did not differ between both populations. Significant correlation was established between rotator peak-torques and javelin throw test among the thrower athletes. Although training program in thrower athletes classically focuses on IRs strengthening, our findings strongly suggest the need for ERs performance improvement. [less ▲]

L’utilisation d’eau de pluie en vue de satisfaire divers usages domestiques se répand de plus en plus dans les habitations wallonnes. Les dispositifs installés et les conditions d’utilisation peuvent varier d’une habitation à l’autre. De plus, l’usage de cette eau est laissé à l’appréciation des occupants. Une dizaine d’installations wallonnes ont fait l’objet d’un suivi permettant de décrire les modes de fonctionnement et de traitement de l’eau, les usages effectifs et les pratiques. Des enquêtes réalisées auprès des usagers ont été complétées par des campagnes d’analyses relatives à la qualité physico-chimique et bactériologique de l’eau stockée. Trois campagnes d’analyses ont été organisées au niveau des mêmes installations en 2001, 2002 et 2006. L’enquête menée auprès des usagers montre que divers usages sont assurés : de l’eau de table au nettoyage de la maison et à l’arrosage du jardin en passant par les lessives et les sanitaires (toilettes, WC). Alors que dans l’ensemble, la qualité de l’eau correspond aux usages, les valeurs obtenues varient cependant d’une installation à l’autre tant au niveau de l’eau brute de la citerne qu’après traitement, ainsi qu’en fonction du contexte environnemental de l’habitation. Les valeurs moyennes obtenues aux différents stades du circuit d’eau pluviale ont été les suivantes : pH (5,6 – 7,3), conductivité (21 – 77 µS/cm), nitrates (2,0 – 5,3 mg/L), ammonium (0,03 – 0,9 mg/L). Seules 2 citernes sur 10 ne contiennent pas de coliformes et streptocoques fécaux (0 par 100 ml). Ces résultats confirment l’intérêt de considérer l’eau de pluie comme une ressource alternative valable, pour autant qu’un minimum de précautions soient prises. [less ▲]

1. In lentic freshwater habitats, the composition of animal assemblages shifts along a gradient from temporary to permanent basins. When habitats with different degrees of permanence are at the scale of the home range of species, they constitute alternatives in terms of energy acquisition through feeding. 2. In this context, previous studies showed an advantage of metamorphic over paedomorphic tiger salamanders (Ambystoma tigrinum) in temporary ponds which are only available to metamorphs. The aim of this study was to establish whether salamanders obtain similar benefits in ponds that do not differ in water permanence and whether salamanders shifted from detrimental to advantageous ponds. To this end, we determined the feeding habits, body condition and movement patterns of the two morphs in a complex of four permanent and four temporary ponds. 3. Consistent with previous studies, metamorphs consumed higher-quality diets than paedomorphs in term of energy intake. However, these differences occurred because metamorphs consumed fairy shrimp in a single temporary pond. Individual movement patterns confirmed that most of the metamorphs used different aquatic habitats both within and between years and that most of them moved from permanent ponds for breeding towards the most profitable temporary pond in terms of foraging. 4. These results indicate that habitat selection by salamanders is optimal in term of energy intake in metamorphs that use high quality ponds independently of hydroperiod. It seems that both spatial and temporal variation can influence the relative foraging success of each morph. [less ▲]
