Recently, Ge et al. (2003) reported a very high accuracy of memory for a highly familiar face. Their Chinese participants had to identify the most veridical appearance of Mao’s face among unaltered and transformed (inter-ocular distance was gradually increased or decreased) versions of his portrait. In the present experiment, the same facial transformations were applied to our participants’ faces to evaluate whether this hyperfidelity for familiar faces is specific to famous individuals whose face is mainly known from a standard portrait or if it could generalise to personally known faces (the own face and a close person’s face). Results showed that performance was not different for the two familiar faces in the recognition task, or between the recognition task and a perceptual discrimination task. The high accuracy of memory previously shown for a very famous face generalises to personally known individuals for whom we have a various visual experience. [less ▲]

A comparison of somatic cell count and antimicrobial susceptibility of subclinical mastitis pathogens in organic and conventional dairy herds.Bovine subclinical mastitis is the most important disease affecting dairy cows. The fluctuating increase in somatic cell count (SCC) that occurs causes major economic losses in dairy industry. This comparative study between conventional and organic dairy herds was conducted in the aim to better characterize which consequences might have different management practices on SCC but also on the frequency of pathogens isolated and their antimicrobial susceptibility. Four conventional and four organic herds, with bulk milk SCC >300x103cells/ml were selected, in which respectively 47 and 44 cows were investigated. Each quarter was sampled 3 times at 15 days interval for SCC, microbiological analysis and antimicrobial susceptibility. In both herd categories, major pathogens isolated were by order of importance Streptococcus uberis, Staphylococcus aureus and Streptococcus dysgalactiae with a great impact on SCC. Coagulase negative staphylococci were the most frequent minor germs and had a moderated but real impact on SCC. In certified organic dairy farms, the three most frequently isolated major pathogens were significantly more susceptible to antimicrobials in vitro. This study suggests that the limited use of antibiotics in organic dairy herds could explain, at least in part, the lower resistance obtained from analysed isolates. [less ▲]

Within a multidisciplinary team of designers, architects and mechanical engineers, and ergonomists, we participate in a research project (ICC) in design and creative interface. This paper describes a participative and iterative approach and reviews the results of field studies involved in the design of a portable tool for finalizing freehand drawings. The results are discussed in terms of Activity Theory and its contribution to this field. [less ▲]

Historical data indicate that pituitary tumors represent 10% of intracranial tumors, while adenomas are noted in approximately 14-23% of normal subjects on autopsy or magnetic resonance imaging (MRI). About 2.5% of these tumors stain positive for GH in histopathologic studies. In contrast, the prevalence of clinically diagnosed acromegaly is lower at 36-69 per million population. Ongoing studies indicate that the actual prevalence of acromegaly in the community may be higher than previous epidemiologic data suggest. Acromegaly can occur both sporadically and in the setting of familial conditions, such as multiple endocrine neoplasia type 1 (MEN1) and Carney complex (CNC). Isolated familial somatotropinoma has been described and newer data suggest that acromegaly may also occur in non-MEN1/CNC families in combination with other pituitary tumor phenotypes. [less ▲]

This paper is devoted to the non linear quasi-steady aerodynamic loading. A linear approximation is often used to compute the response of structures to buffeting forces. Some researchers have however shown that it is possible to account for the non linearity of this loading. This non linearity can come (i) from the squared velocity or (ii) from the shape of the aerodynamic coefficients (as functions of the wind angle of attack). In this paper, we show that this second origin can have significant implications on the design of the structure, particularly when the non linearity of the aerodynamic coefficient is important (obvious, isn’t it?) or when the transverse turbulence is important.

Nowadays, the computer simulations of metal forming processes using the finite element method (FEM), have reached some level of maturity. Inverse problems purpose is to determine one or more of these forming processes simulations input data, leading to a desired result. A first example that has now become classical is called parameter identification. It consists in evaluating the material parameters for material behaviour laws that would lead to the most accurate model, minimising the difference between experimental and numerical results. Another example, which is much less extensively described in the literature is the initial geometry and tool shape design, which consists in determining the initial shape of the specimen and/or the shape of the forming tools, in order to provide the desired final geometry after forming process. In this paper, we will show how some optimisation methods are able to solve this shape optimisation problems. We will also compare the efficiency of the proposed numerical methods. [less ▲]

Research interest in the thermo-mechanical behaviour of soils is growing as a result of an increasing number of geomechanical problems involving thermal effects. This paper addresses various issues concerning the thermo-mechanical behaviour of soils. Starting from experimental evidence of non-linearity and hardening that heating causes in clayey soils, a general thermo-plastic formulation is then introduced for the derivation of the constitutive equations. After that, constitutive modelling is presented and treated in the context of elasto-plasticity. Numerical simulations support the theoretical aspects of the paper by showing performances of the constitutive model. [less ▲]
