(1992)The recombinant plasmid pTR‐3 was previously shown to contain part of the 16S and 23S ribosomal RNA genes and the spacer region between the two genes from operon rrnT, from Thiobacillus ferrooxidans. The spacer region was ...

(Elsevier Ltd., 2005-08-24)This article analyses the work of Robert Rosen on an interpretation of metabolic networks that he called ðM;RÞ systems. His main contribution was an attempt to prove that metabolic closure (or metabolic circularity) could ...

Organometallic derivatives of polyphosphazenes as precursors for metallic nanostructured materials (SPRINGER, 2006-12)Co-polyphosphazenes containing anchored organometallic fragments are useful precursors for nanostructured metallic materials. Pyrolysis in air at 800 degrees yields metallic nanoparticles of the type, M degrees/M (x) O (y) ...

(Elsevier, 2000)The three new organometallic hydrazines [Fe(η5-Cp)(η6-RC6H4NHNH 2)]+PF6 -, Cp=C5H5, R=H, [1]+PF6 -; m-Me, [2]+PF6 -; p-MeO, [3]+PF6 -, were synthesised and characterised. They were obtained in CH2Cl2 by reaction of the ...

(SOC NEUROSCIENCE, 2010-01-11)The lateral line system of teleosts has recently become a model system to study patterning and morphogenesis. However, its embryonic origins are still not well understood. In zebrafish, the posterior lateral line (PLL) ...
-
(Sociedad Mexicana de Fisica, 2014)A mechanism that produces conical dispersion relations is presented. A Kronig Penney one dimensional array with two different strengths delta function potentials gives rise to both the gap closure and the dispersion relation ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-05)We addressed phylogenetic relationships in the genus Trachurus using cytochrome b gene and D-loop sequences. The trees showed five groups: (1) the Southwest Pacific species (T. japonicus, T. novaezelandiae, and T. declivis); ...

Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes : Furnariidae) (BLACKWELL, 2006-10)1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...
