The availability of high-density bovine genotyping arrays made implementation of genomic selection possible in dairy cattle. Development of low-density single nucleotide polymorphism (SNP) panels will allow the extension of genomic selection to a larger portion of the population. Prediction of ungenotyped markers, called imputation, is a strategy that allows using the same low-density chips for all traits (and for different breeds). In the present study, we evaluated the accuracy of imputation with low-density genotyping arrays in the Dutch Holstein population. Five different sizes of genotyping arrays were tested, from 384 to 6,000 SNP. According to marker density, the overall allelic imputation error rate obtained with the program DAGPHASE, which relies on linkage disequilibrium and linkage, ranged from 11.7 to 2.0%, and that obtained with the program CHROMIBD, which relies on linkage and the set of all genotyped ancestors, ranged from 10.7 to 3.3%. However, imputation efficiency was influenced by the relationship between low-density and high-density genotyped animals. Animals with both parents genotyped had particularly low imputation error rates: <1% with 1,500 SNP or more. In summary, missing marker alleles can be predicted with 3 to 4% errors with approximately 1 SNP/Mb (approximately 3,000 markers). The CHROMIBD program proved more efficient than DAGPHASE only at lower marker densities or when several genotyped ancestors were available. Future studies are required to measure the effect of these imputation error rates on accuracy of genomic selection with low-density SNP panels. [less ▲]

Le réseau microvasculaire de la peau joue des rôles physiologiques majeurs en oxygénant les tissus et en permettant des échanges thermiques finement régulés. Son parcours résistif et capacitif module les résistances périphériques au débit sanguin. La microvascularisation est sous l’influence de divers facteurs, mais globalement, elle semble presque immuable dans la peau saine. En revanche, certaines circonstances pathologiques engendrent des hyperplasies ou des hypoplasies vasculaires. Parfois aussi, le réseau semble garder son extension normale, mais sa structure intime est remaniée. Cette revue est un florilège d’aspects microscopiques associés à des perturbations majeures de la fonctionnalité vasculaire cutanée. [less ▲]

Tertiary models are proposed in order to predict the growth of Listeria monocytogenes and Salmonella spp. in pork minced meat packaged under stretch film. The models have been calculated from challenge-tests at 8°C (L. monocytogenes) and 12°C (Salmonella), the meat being artificially contaminated at 2 log cfu pathogen/g. In a second step, they have been validated at 5, 8 and 10°C for L. monocytogenes (r² : 0.94, 0.98 and 0.95) and 8, 10 and 12°C for Salmonella (r³ : 0.80, 0.92 and 0.98). [less ▲]

In many cases, the numerical computation of mechanical problem with Finite Element Method has to transfer some information between two different meshes. For example, if a remeshing is needed or if several meshes are used (e.g. one for a thermal problem and another one for a mechanical problem). In spite of the research on the Transfer Methods, none of them has been so far clearly established as the best. Each method has advantages and disadvantages. Many problems can happen during the field transfer, like the minimization of the numerical diffusion, the value of the field on the boundaries, etc. This paper compares on the one hand the performances of the Field Transfer Method by classical interpolation with on the other hand one using Mortar Elements. The comparison of the two methods is based on two indicators: the numerical diffusion and the evaluation of the field on the boundaries. In this paper, only the continuous fields are considered.

Due to the frequency–energy dependence of nonlinear oscillations, nonlinear dynamical absorbers present interesting properties for mitigating unwanted vibrations in mechanical systems. Unlike the tuned mass damper, the functional form of a nonlinear absorber is not known a priori and must be determined. This short note addresses this issue when a light-weight nonlinear absorber is attached to a nonlinear primary structure. Numerical simulations demonstrate that the determination of an adequate functional form may be directly linked to the frequency–energy dependence of the primary structure. [less ▲]

We present tree community diversity, species composition, basal area and aboveground biomass of three forest types in the Dja Biosphere Reserve, in South-East Cameroon, part of the contiguous tropical forest of the Congo Basin. A total of fourteen, 1 ha, plots were established in heterogeneous terra firme forests (TFF), Gilbertiodendron dewevrei forests (GDF) and periodically flooded forests (PFF). A total of 281 tree species with diameter ‡10 cm were recorded. The Shannon diversity index was significantly higher in TFF (5.7 ± 0.28) and PFF (5.6 ± 0.23) than in GDF (2.29 ± 0.48) (ANOVA, F2,11 = 139.75, P < 0.001). While tree density did not differ between forest types (F2,11 = 3.50, P = 0.06), basal area differed significantly (F2,11 = 7.38, P = 0.009), as did aboveground biomass (F2,11 = 17.95, P < 0.001). Mean AGB values were respectively, 596.1 ± 62.24, 401.67 ± 58.06 and 383.14 ± 61.91 Mg ha)1 in GDF, TFF and PFF. Variation in the abundance of trees with large diameter was the main reason for these differences. Few dominant species made the greatest contribution to the AGB. G. dewevrei, accounted for 83% of AGB in GDF, Penthaclethra macrophylla for 9.9% in TFF and Uapaca heudolotii for 10.6% in PFF. The importance of preserving G. dewevrei forest in the context of ‘Reducing Emissions from Deforestation and forest Degradation’ (REDD) policies is discussed. [less ▲]

Among the numerous changes which the notion of family has known over time, we are interested here in the normalization/acceptability of the divorce (or separation). We postulate that, in a context where these modifications are less and less ritualized and thus, less and less representable, the family (whose achronic character we shall differentiate from the diachronic) has no access to a social representability/acceptability of its separations. According to us, the family suffers then from an identity crisis of which the child, sometimes on top of his individual sufferings, can be the symptom. Then it remains for the therapists to make up for this lack of representability of separations, while remaining lucid about the limits of their interventions. [less ▲]
