Total element determination and chemical fractionation were carried out in airborne particulate matter (PM10) from the Cerrillos monitoring station in Santiago, Chile, sampled in July (winter), 1997-2003. Element concentration ...

The numerical simulation of soil-pile interaction problems, by means of full 3Dfinite element models, involves a large number of degrees of freedom (DOF)and difficulties during the mesh generation process. In order to ...

Exceptional synthetic transformations have been achieved through the years by the use of transition metal catalysts. On the contrary, only a few industrialized processes use main group based catalysts due to its low ...

New bridged di-germanocenes and di-stannocenes 2 have been synthesized from a reaction between (pentamethylcyclopentadienyl)metal chloride and the dilithium salts of the corresponding linked cyclopentadienyl ligands (spacer: ...

The aim of this study was to evaluate the effect of unilateral angular misfit of 100 Km on stress distribution of implant-supported single crowns with ceramic veneering and gold framework by three-dimensional finite element ...

Transposable elements are repetitive sequences with the capacity to move inside of the genome. They constitute the majority of the eukaryotic genomes, and are extensively present in the human genome, representing more than ...

Transposable elements constitute a remarkable fraction of the eukaryote genome and show particular capacity to move and insert in specific regions of the genome. This study identified the retrotransposable elements Rex1 ...
