(Table, page 500) Geochemistry of a pancake-shaped concretion from lake Charlotte, Canada

A pancake-shaped concretion from Ship Harbour Lake, a small freshwater lake in eastern Nova Scotia (now named Lake Charlotte) is part of collection sent to the National Museum of Canada by Mr. R. A. Logan, of the Pan American Airvays. These concretions are of similar to the well-known marine concretions with a composition similar to wad. These are known only from abyssmal depths of the sea in the red clay deposits, while the present concretions occur in very shallow lake waters. They should be of interest to geologists, who may be concerned with the rather difficult problem which some concretions raise of distinguishing between concretions of syngenitic and epigenetic origin.

Bridges E-2 and E-3 in the new railway to the Northwest of Spain

During the years 2001 to 2007 it has been constructed in Spain the new railway line of high speed (L. H. S.)that connects Madrid with Valladolid with a length of 179.6 kilometres.

Great roof marquee in the new railway station for high speed trains of Málaga

The new railway station of María Zambrano for AVE (Spanish high-speed trains) located in Malaga, has been inaugurated in November 2006, just on the site of the former railway station. The new railway station with an investment of 134.7 million Euros occupies a surface of 51.377 m2, five times the surface of the former station. The enclosure is the biggest intermodal transport and commercial center of Spain which comprises a parking of 21,000 m2 for 1,300 parking places, one commercial area and a hotel of 35 m height, with a total extension constructed of approximately 100,000 m2.

Hoxb6 can interfere with somitogenesis in the posterior embryo through a mechanism independent of its rib-promoting activity

Formation of the vertebrate axial skeleton requires coordinated Hox gene activity. Hox group 6 genes are involved in the formation of the thoracic area owing to their unique rib-promoting properties. Here we show that the linker region (LR) connecting the homeodomain and the hexapeptide is essential for Hoxb6 rib-promoting activity in mice. The LR-defective Hoxb6 protein was still able to bind a target enhancer together with Pax3, producing a dominant-negative effect, indicating that the LR brings additional regulatory factors to target DNA elements. We also found an unexpected association between Hoxb6 and segmentation in the paraxial mesoderm. In particular, Hoxb6 can disturb somitogenesis and anterior-posterior somite patterning by dysregulation of Lfng expression. Interestingly, this interaction occurred differently in thoracic versus more caudal embryonic areas, indicating functional differences in somitogenesis before and after the trunk-to-tail transition. Our results suggest the requirement of precisely regulated Hoxb6 expression for proper segmentation at tailbud stages.
