To identify the callipyge mutation, we have resequenced 184 kb spanning the DLK1-, GTL2-, PEG11-, and MEG8-imprinted domain and have identified an A-to-G transition in a highly conserved dodecamer motif between DLK1 and GTL2. This was the only difference found between the callipyge (CLPG) allele and a phylogenetically closely related wild-type allele. We report that this SNP is in perfect association with the callipyge genotype. The demonstration that Solid Gold-the alleged founder ram of the callipyge flock-is mosaic for this SNP virtually proves the causality of this SNP in the determinism of the callipyge phenotype.

In order to simplify, facilitate and provide a methodology for the analysis of corpuses (interviews, focus groups, press articles, etc.), Spiral's Mosaiqs project offers a CAQDAS service that is both simple and efficient. The exploration, firstly, enables the professional sciences to prepare for field work, including interviews, discussions son or any other text. It allows the development of the draft of the analysis grid, the professional socialization of its object of study and preparing for the examination phase. Finally, the analysis gives the professional the raw material that will be required for the preparation of its findings. Mosaiqs you work more effectively, more faithful to your body and in record time. [less ▲]

Si, comme l'écrit Lucien Dällenbach, la mosaïque constitue une allégorie de la mondialisation, ce n'est pas seulement par analogie. En effet, les technologies numériques et en particulier les réseaux, instruments privilégiés de la mondialisation, sont devenus producteurs de mosaïques (images et textes) à grande échelle. Cette idée est illustrée par l'analyse du principe de la photomosaïque, très répandue sur la toile, et de la production de l'artiste français Reynald Drouhin. [less ▲]

Meshes are the actual standard in abdominal wall repair. Commercial medical meshes are however either unavailable or unaffordable too expensive for developing countries. Therefore in most resource-poor developing countries a traditional sutured repair is still commonplace although with significantly inferior results. Sterilized mosquito nets have been recently roposed by several authors to replace medical meshes in low-income countries . However in the perspective of their clinical use a better understanding of this mosquito net is obviously requested both in terms of material properties and of in vivo biocompatibility. [less ▲]

The Mossbauer spectra of the Na1-xLixMnFe2(PO4)(3) compounds, with x = 0,00, 0.25, 0.50, and 0.75, have been measured between 90 and 295 K and analyzed in terms of a model which takes into account the next-nearest neighbor interactions within the alluaudite structure. Surprisingly, the spectra reveal an unexpected presence of iron(II) in these compounds; the amount of iron(II) is observed to decrease from 19 to 15 atomic percent of the total iron content with increasing x. The temperature dependence of the Fe2+ and Fe3+ isomer shifts agrees with that expected from a second-order Doppler shift and the resulting iron vibrating masses and Mossbauer lattice temperatures are within the expected range of values for iron cations in an octahedral environment. The temperature dependence of the Fe2+ quadrupole splitting has been fit with the Ingalls' model and the results yield a ground state orbital splitting of ca. 500 cm(-1) for the iron(II) sites. The compositional dependence of the isomer shifts and Fe2+ content can be understood in terms of a decrease in the unit-cell volume with increasing substitution of sodium by lithium, a substitution which does not influence the observed quadrupole splittings.

Powder mixtures of (FeyN)(x) and (Al2O3)(1-x) or (SiO2)(1-x) with x = 0.2 and 0.6 and y = 3.8 have been ball milled for 4, 8, 16, 32, 64, and 128 h and their magnetic properties and Mossbauer spectra have been measured. The 5 and 295 K saturation magnetizations decrease with increasing milling time as a result of decreasing particle sizes. Fits with the Langevin function of the field dependence of the magnetization yield particle sizes that are slightly smaller than those determined from a Scherrer analysis of the broadening of the X-ray diffraction peaks. The Mossbauer spectra have been fit with a distribution of hyperfine fields between 0 and 40 T and the peaks in the distribution assigned to the different iron nitride phases present in the nanocomposites. This analysis of the Mossbauer spectra indicates that the gamma'-Fe4N phase present in FeyN is transformed into epsilon-Fe3+xN and alpha-iron by the milling process. The weighted average field decreases and the weighted average isomer shift increases with milling time, as expected for the simultaneous effects of size reduction, the above phase transformation, and mixing with the oxides. A peak in the hyperfine field distribution at 4 T indicates the presence of small superparamagnetic particles, a presence which is also confirmed by the temperature dependence of the Mossbauer spectra and the failure of the magnetization to saturate even at applied fields of 5.5T.

The iron-57 Mossbauer spectra of the GdCo4-xFexB compounds, where x is 0.10, 0.15, 0.20, 0.25, 1, 2, 2.5, and 2.6, have been measured at room temperature and reveal relatively small iron hyperfine fields of approximately 12-18 T, relatively large quadrupole interactions of approximately +0.9 and -1 mm/s, and three very different types of spectra for x=0.10 and 0.15, x=0.25, 1, and 2, and x=2.5 and 2.6. The differences result from both the different easy magnetization directions in these compounds and the different cobalt and/or iron occupancies of the crystallographic 2c and 6i sites. The spectra have been fitted by calculating the spectral absorption with the complete iron-57 nuclear excited state Hamiltonian for the iron 2c and 6i sites. The fits have used an asymmetry parameter eta and Euler angles theta and phi that relate the hyperfine field to the iron electric field gradient axes of each crystallographic site in an orientation that is consistent with the structural and magnetic properties of the site. The results of the fits indicate both that the full Hamiltonian approach is required for physically reasonable spectral fits and that the small observed fields result from the presence of large orbital contributions which subtract from the Fermi contact contributions to the magnetic hyperfine fields of the two sites. The iron 2c occupancy obtained from the Mossbauer spectral area has been used to model the compositional dependence of the magnetic anisotropy constant in the GdCo4-xFexB compounds.

The magnetic phase transitions in the FeMnP1-xAsx compounds with x= 0.25, 0.35, 0.45, 0.50, and 0.55, have been studied by iron-57 Mossbauer spectroscopy. The ferromagnetic and antiferromagnetic spectra have been analyzed with a model that takes into account the random distribution of the P and As near-neighbor anions of a given iron site. This distribution is a binomial distribution of the contributions to the spectra of each iron with n As near neighbors. A magnetostriction model has been used to characterize the temperature induced paramagnetic to ferromagnetic first-order phase transition and order parameters, eta(F)=2.6, 2.3, 2.0, 1.57, and 1.43 have been obtained for x=0.25, 0.35, 0.45, 0.50, and 0.55, respectively. A detailed phase diagram has been derived from the Mossbauer spectral analysis and reveals a magnetic triple point at x=similar to0.35 and similar to210 K. A model that takes into account the random binomial P and As distribution and the contribution from the iron and manganese magnetic sublattices yields excellent fits of the spectral components assigned to the ferromagnetic and incommensurate antiferromagnetic components for the x=0.25 and 0.35 compounds at all temperatures.

The Mossbauer spectra of the YCo4-xFexB compounds, where x is 1, 2 and 3, have been measured at 78 and 295 K and reveal relatively small iron hyperfine fields of about 15 T, relatively large quadrupole interactions of about +1.0 and -1.0 mm s(-1) and very different spectra for YCo3FeB and YCo2Fe2B as compared with YCoFe3B. As a consequence, the spectra have been fitted with a full Hamiltonian by adjusting the hyperfine parameters of the iron 2c and 6i sites found in these compounds. The fits have used an asymmetry parameter, eta and Euler angles, theta and phi, that relate the hyperfine field to the iron electric field gradient axes of each iron site in an orientation that is consistent with the structural and magnetic properties of the site. The fits indicate that the relative areas of the spectral components assigned to the two iron 2c and 6i sites are in agreement with the iron occupancy of the sites as determined by neutron diffraction. The results of the fits also indicate both that the full Hamiltonian approach is required for physically reasonable spectral fits and that the small observed fields result from the presence of large orbital contributions which subtract from the Fermi contact contributions to the magnetic hyperfine fields of the two sites.

Palynological research project in collaboration with CENPES/BPA palynologists (Petrobras). Second project (2010-2012) Presented next are details of the consulting research project on "Upper Devonian – Lower Pennsylvanian miospore collection and database" devised exclusively for CENPES/BPA palynologists. Project description The mounting of a palynological reference collection and database of biostratigraphically important miospores from the Upper Devonian through the Lower Pennsylvanian (Namurian). This includes a minimum of 150 selected species from Western Europe, and a minimum of 150 selected species from Gondwana. It should be noted that several stratigraphically relevant species are common to both regions, but the collection will emphasize regional differences in their size and morphography. Two main parts will compose the final product: the reference slide collection proper, and the database. a) Sufficiently well preserved specimens (identifiable at species level) will be located on conventional palynological slides by means of an England Finder graticule. The slides will be numbered and stored in special boxes. The slides will be mounted at Université de Liège, Belgium, with the whole assemblage of palynomorphs recovered from the organic residues after the processing of selected samples at the University. Provenance data for each reference slide will be provided whenever possible, including: country, basin, rock unit (fm.), biostratigraphic unit, and age. An appropriate number of specimens (so as to cover an array of size and morphological variability) will be referenced for each species - although not necessarily on the same slide. Every selected specimen will be photographed. All these data will be stored in the database. b) The database will be organized by using the software FileMaker Pro (we do not provide the software - for more information see http://www.filemaker.co.uk/). The database will be saved on CDRom or DVD media. The database will consist of: - The original description of each species and a high-resolution scanned (PDF) copy of publications illustrating the type specimens. A synthetic additional description of the specimens will be added, and the main differences from morphologically similar species will be stressed. - Synonymy lists. - Stratigraphic ranges (age and zonal span). - Geographic distribution. - A complete list of bibliographic references from which the above data are compiled. - Reference slide data (slide numbers and England Finder coordinates). - High-resolution pictures of all selected specimens in the slide collection, including detail pictures when deemed necessary for the species characterization. - A keyword research tool (e.g,: search for morphology, stratigraphy, taxa names, slides).

Palynological research project in collaboration with CENPES/BPA palynologists (Petrobras). First project (2009) Presented next are details of the consulting research project “Ordovician – Middle Devonian miospore collection and database”, devised for exclusive use by CENPES/BPA palynologists. The project consists in mounting a palynological reference collection of biostratigraphically most important spores and cryptospores from the Ordovician through the Middle Devonian. It implies a minimum of 150 selected species. Most of them will be from the Gondwana Supercontinent. However, some stratigraphically relevant species known from Euramerica will be also included, as they could prove potentially useful for future work and comparison with Gondwanan taxa. Two main parts will compose the final product of the project: the reference slide collection proper, and the database. a) Sufficiently well preserved specimens (identifiable at species level) will be located on conventional palynological slides by means of an England Finder graticule.
