Pre served in an 18th-century copy in the Biblio thèque Royale of Belgium (KBR, ms. 17349-60, fols. 13-23v), the Annales Maximiniani were published in 1881 by Georg Waitz in the MGH, as a continuation of the Chronicon universale – 741. The edition poses problems, most notably in the relationships posited between the Annales Maximiniani and other contemporary historical sources. A compilation of various Carolingian texts, the Annales Maximiniani appear to be more original than has been thought. They are not simply the continuation of a chronicle, but rather an interesting early ninth-century attempt to insert into Bede’s Chronica Majora an account of the rise of the Pippinides and Carolingians, composed of carefully edited selections from a number of sources.

We show that a double emulsion (oil in water in oil) can be created starting from a compound droplet (surfactant solution in oil). The compound drop bounces on a vertically vibrated liquid surface. When the amplitude of the vibration exceeds a threshold value, the oil layer penetrates the water content and leaves a tiny oil droplet within. As this phenomenon occurs at each vigorous impact, the compound drop progressively transforms into a double emulsion. The emulsification threshold, which is observed to depend on the forcing frequency but not on the drop size, is rationalized by investigating the impact of compound drops onto a static liquid surface. The droplet creation occurs when the kinetic energy released at impact is larger than the energy required to deform the compound drop, namely when the Weber number is higher than a given threshold value.

Imputation of missing genotypes is important to join data from animals genotyped on different single nucleotide polymorphism (SNP) panels. Because of the evolution of available technologies, economical reasons, or coexistence of several products from competing organizations, animals might be genotyped for different SNP chips. Combined analysis of all the data increases accuracy of genomic selection or fine-mapping precision. In the present study, real data from 4,738 Dutch Holstein animals genotyped with custom-made 60K Illumina panels (Illumina, San Diego, CA) were used to mimic imputation of genotypes between 2 SNP panels of approximately 27,500 markers each and with 9,265 SNP markers in common. Imputation efficiency increased with number of reference animals (genotyped for both chips), when animals genotyped on a single chip were included in the training data, with regional higher marker densities, with greater distance to chromosome ends, and with a closer relationship between imputed and reference animals. With 0 to 2,000 animals genotyped for both chips, the mean imputation error rate ranged from 2.774 to 0.415% and accuracy ranged from 0.81 to 0.96. Then, imputation was applied in the Dutch Holstein population to predict alleles from markers of the Illumina Bovine SNP50 chip with markers from a custom-made 60K Illumina panel. A cross-validation study performed on 102 bulls indicated that the mean error rate per bull was approximately equal to 1.0%. This study showed the feasibility to impute markers in dairy cattle with the current marker panels and with error rates below 1%. [less ▲]

Despite growing evidence of the detrimental effect of chemical substances on organisms, limited research has focused on changes in behavioral patterns, in part due to the difficulties to obtain detailed quantitative data. Recent developments in efficient computer-based video analyses have allowed testing pesticide effects on model species such as the zebrafish. However, these new techniques have not yet been applied to amphibians and directly to conservation issues, i.e. to assess toxicological risks on threatened species. We used video tracking analyses to test a quantitative effect of an environmental contaminant on the locomotion of amphibian tadpoles (Rana temporaria) by taking into account cumulative effects. Because recent research has demonstrated effects of de-icing salts on survival and community structure, we used sodium chloride in our experimental design (25 replicates, 4 concentrations, 4 times) to test for an effect at the scale of behavior at environmentally relevant concentrations. Analysis of 372 1-hr video-tracks (5 samples per sec) showed a complex action of salts on behavioral patterns with a dose and cumulative response over time. Although no effects were found on mortality or growth, the highest salt concentrations reduced the speed and movement of tadpoles in comparison with control treatments. The reduced locomotor performance could have detrimental consequences in terms of tadpoles’ responses to competition and predation and may be an indicator of the low concentration effect of the contaminant. On one hand, this study demonstrates the usefulness of examining behavior to address conservation issues and understand the complex action of environmental factors and, more particularly, pollutants on organisms. On the other hand, our results highlight the need of new computerized techniques to quantitatively analyze these patterns. [less ▲]

The cyclotron of the IPNAS-CEA laboratory of the University of Liege (Belgium) has built a new high-energy, high-resolution beam line based on the use of a pair of 900 bending magnets showing a energy resolution of Delta E = 1.9 +/- 0.4 keV comparable to that of electrostatic IBA installations. In the 6-20 MeV energy range the contribution of non-Rutherford events to scattering spectra became important and are not very well known. In order to improve our knowledge in that field, a new vacuum chamber especially dedicated to differential cross-section measurements has been constructed. First results obtained with the new set-up are presented. (C) 2010 Elsevier B.V. All rights reserved. [less ▲]

We have deposited III-V alloys on 200 mm Si miscut wafers with an oxide pattern. The selective epitaxial growth (SEG) of GaAs in large windows defined by SiO2 lines on a thick strained-relaxed Ge buffer layer served as a test vehicle which allowed us to demonstrate the integration of a III-V material deposition process step in a Si manufacturing line using an industrial reactor. High quality GaAs layers with high wafer-scale thickness uniformity were achieved. In a subsequent step, SEG of InP was successfully performed on wafers with a 300 nm shallow trench isolation pattern. The seed layer morphology depended on the treatment of the Ge surface and on the growth temperature. The orientation of the trench with respect to the substrate miscut direction had an impact on the quality of the InP filling. Despite of the challenges, such an approach for the integration of III-V materials on Si substrates allowed us to obtain extended-defect-free epitaxial regions suitable for the fabrication of high-performance devices.

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 ▲]

According to EN 1504-10 and ACI Concrete Repair Manual, bond strength and interface quality are the main features of repair system necessary to be assessed. Pull-off test is most commonly used for bond strength evaluation but growing interest in nondestructive techniques (NDT) is recently noted. Impact-echo (IE) is treated as the most promising one for this purpose. The aim of this paper is to analyze an effect of bond quality on stress wave propagation in repair systems. A group of samples has been prepared in order to obtain repair systems of different bond quality. Prior to repair, quality of concrete substrates has been characterized according different techniques: compressive strength, superficial cohesion, surface roughness index and cracking quantification. Than a polymer-modified repair mortar has been applied. After hardening, IE signals have been recorded and pull-off bond strength determined. The relationships between parameters characterizing surface quality, bond strength, IE frequency spectrum and results of wavelet analysis of IE signal have been analyzed. [less ▲]
