The 4M-µpump project attempts to breach the gap between traditional mechanics and micro mechanics and this in two ways. The first one consists in producing a general set of rules suitable for the miniaturisation of well-known macromachines. The second one consists in developing this fundamental aspect of the research through the design and realization of an implantable pump dedicated to the administration of medication agents inside the human body. The project thus touches upon the field of design, manufacturing, metrology and assembly of mini components as well as the study of minimotors. [less ▲]

This article present the discovery context of Neolithic ceramic sherds in stratum 4 (formerly attributed to the Late Mesolithic) at Trou Al'Wesse. The vertical distribution of the archaeological material and stratigraphic data demonstrate that these sherds do not belong to the Mesolithic assemblage. Post-depositional processes in front of the cave entrance have reworked these sherds and Mesolithic lithic artifacts. The stratigraphy also shows that, against the walls, there is no mixture between the two occupations. [less ▲]

Tachycardias arise from an arrhythmogenic substrate triggered by a random factor (generally an extrasystole) and modulated by the autonomic nervous system. The three components are interactive, but their intensity and conjunction vary continuously. During the last decade, major achievements have been made to clarify definition and classification of data reported in the literature, helping our understanding of the mechanisms of ventricular arrhythmias. Nowadays, the pathophysiology of cardiac arrhythmias is well-known at the cellular and molecular ion channel activity. The progress of epidemiology and molecular genetics have allowed a better knowledge of the genotype-phenotype correlation in young patients presenting syncopes due to torsades de pointes or polymorphic ventricular tachychardia episodes which may degenerate into ventricular fibrillation and cause sudden death. The data of numerous large prospective randomised studies have led to more rational treatments with the progressive withdrawal of class I antiarrhythmics and their replacement by betablocking agents. The surgical approach of ventricular tachycardia has been overcome by the automatic implantable defibrillator and in some well-defined clinical situations, catheter ablation is used. [less ▲]

The following text deals with casting of copper-nickel alloys. They are high added values materials. The research contains two main parts. Laboratory tests (completed with bibliography) that provide thermal and mechanical properties of the ingot and the mould but also heat transfer coefficients between the ingot and its environment (mould, air and water). These parameters are required in the second part : development and validation of numerical modelization by the finite element method to optimise the industrial process. [less ▲]

In this paper, I offer a thorough analysis of the provisions of the Code of Private International law (Act of 16 July 2004) regarding the recognition and enforcement of foreign judgments in Belgium (artt. 22 ff). The emphasis is on the differences with the regime which prevailed before the entry into force of the Code. At the same time I indicate what differences remain between the regime put in place by the Code and the one prevailing within the European Judicial Area, with Regulation 44/2001 as main comparison point.

The Number Decision Diagram (NDD) has recently been introduced as a powerful representation system for sets of integer vectors. NDDs can notably be used for handling sets defined by arbitrary Presburger formulas, which makes them well suited for representing the set of reachable states of finite-state systems extended with unbounded integer variables. In this paper, we address the problem of counting the number of distinct elements in a set of numbers or, more generally, of vectors, represented by an NDD. We give an algorithm that is able to produce an exact count without enumerating explicitly the vectors, which makes it capable of handling very large sets. As an auxiliary result, we also develop an efficient projection method that allows to construct efficiently NDDs from quantified formulas, and thus makes it possible to apply our counting technique to sets specified by formulas. Our algorithms have been implemented in the verification tool LASH, and applied successfully to various counting problems. [less ▲]

Founding myths, miscellaneous items in the press, along with a long series of detailed witnesses reveal figures of children who grew up on the edge of the human world, in the company of beasts, sometimes, in solitude and réclusion. Following the stories of feral children amounts to considering in the long term every situation where hypotheses based on theories coming from various perspectives of thought could be evaluated by comparison with man in his "natural state". Feral children seem to be inseparable from the problem of the great Nature /Culture divide and from the way in which our relationships with the non-human world are established [less ▲]

In the context of precision agriculture, the knowledge of soil strength variability at the field scale may be useful for improving site-specific tillage. Moreover, rapid and accurate sensing methods for soil physical properties determination would favourably replace labour intensive, time-consuming and expensive soil sampling and analysis. This study aims at validating conclusions of a previous study which was conducted to develop a soil strength in field conditions. The coupled acquisition of the sensor's signals and the corresponding DGPS positions allowed establishment of maps for the three measured outputs, namely the horizontal force (Fx), the vertical force (FZ) and the moment (My). In order to study the relationships between measured forces and soil physical parameters, a series of soil properties were measured on soil cores collected in 10 reference plots. Significant correlations were found between Fx and the average resistance to cone penetration at 25 cm depth and between Fx and the average soil moisture at 30 cm depth. The sensing method proved its capability to characterize within-field soil variability. [less ▲]

First-lactation test-day milk, fat, and protein yields from New York, Wisconsin, and California herds from 1990 through 2000 were adjusted additively for age and lactation stage. A random regression model with thirdorder Legendre polynomials for permanent environmental and genetic effects was used. The model included a random effect with the same polynomial regressions for 2 yr of calvings within herd (herd-time effect) to provide herd-specific lactation curves that can change every 2 yr. (Co)variance components were estimated using expectation-maximization REML simultaneously with phenotypic variances that were modeled using a structural variance model. Maximum heritability for test-day milk yield was estimated to be ∼20% around 200 to 250 d in milk; heritabilities were slightly lower for test-day fat and protein yields. Herd-time effects explained 12 to 20% of phenotypic variance and had the greatest impact at start of lactation. Variances of test-day yields increased with time, subclass size, and milking frequency. Test month had limited influence on variance. Variance increased for cows in herds with low and high milk yields and for early and late lactation stages. Repeatabilities of variances observed for a given class of herd, test-day, and milking frequency were 14 to 17% across nested variance subclasses based on lactation stage. [less ▲]

BACKGROUND: The renal chloride channel ClC-5, which is responsible for Dent's disease, is coexpressed with the vacuolar H+-ATPase in proximal tubules (PT) and alpha-type intercalated cells (IC) of the mature kidney. Neonatal cases of Dent's disease suggest that ClC-5 distribution must be acquired before birth. However, the ontogeny of ClC-5, and its processing and segmental distribution with respect to related proteins during nephrogenesis remain unknown. METHODS: Immunoblotting, real-time polymerase chain reaction (RT-PCR), immunostaining, and deglycosylation studies were used to investigate the expression, distribution, and maturation of ClC-5 during mouse and human nephrogenesis, in comparison with H+-ATPase, type II carbonic anhydrase (CAII), and aquaporin-1 (AQP1). RESULTS: An early induction (E13.5-E14.5) of ClC-5 was observed in mouse kidney, with persistence at high levels through late nephrogenesis. This pattern contrasted with the progressive expression of H+-ATPase and AQP1, and the postnatal upregulation of CAII. Immunostaining showed expression of ClC-5 in ureteric buds and, from E14.5, its location in developing PT. From E15.5, ClC-5 codistributed with H+-ATPase in PT cells and alpha-type IC. In the human kidney, ClC-5 was detected from 12 gestation weeks; its distribution was similar to that observed in mouse, except for a later detection in IC. Although mouse and human ClC-5 proteins are glycosylated, biochemical differences between fetal and adult proteins were observed in both species. CONCLUSION: The segmental expression of ClC-5 and H+-ATPase is essentially achieved during early nephrogenesis, in parallel with the onset of glomerular filtration. These data give insight into PT and IC maturation, and explain early phenotypic variants of Dent's disease. [less ▲]
