La Mancomunitat de les Valls. Fragilidad, paisaje y desarrollo
No full textEste libro es la continuación de la serie editada por la UPV a propuesta del Taller de Urbanismo y Paisaje. Está compuesto por cinco artículos de investigación que invitan a la reflexión sobre la necesidad de difusión de ideas sobre las estrategias de rehabilitación urbana más aconsejables, que contribuyan al desarrollo sostenible y favorezcan las formulas de intervención sobre tejidos, perfiles urbanos y espacios verdes.En definitiva, se trata de un libro que versa sobre la fragilidad, como define su título, la fragilidad de lo belloAguilar Alonso, MD.; Alonso Salvador, M.; Blasco Sánchez, MDC.; Ramón Huidobro, J.; Insausti Machinandiarena, P.; Martínez Pérez, FJ.; Vigil De Insausti, A.

Co Doping Effects On The Magnetic And Magnetoresistance In Sm 0.35nd0.35pb0.30mn1-xco Xo3 (x = 0, 0.1, 0.2)
No full textPolycrystalline samples of the Sm0.35Nd0.35Pb 0.3Mn1-xCoxO3 (x = 0, 0.1, 0.2) at low magnetic fields has been studied by AC susceptibility, and field cooled and zero field cooled magnetisation measurements. We conclude that a small amount of Co substitution tends to destroy the double exchange and broadens the coexistence region of the cluster-glass and ferromagnetic states. Also, the Co doping suppresses the large negative magnetoresistance and it becomes small for x = 0.2. © 2001 Published by Elsevier Science B.V.226-230PART I834836Martin, C., Maignan, A., Hervieu, M., Raveau, B., (1999) Phys.

Magnetotransport Properties Of The Sm0.35nd0.35m0.3mn1-xfexo 3 (m = Pb, Cd; X = 0, 0.1) Manganites
No full textPolycrystalline samples of the mixed-valence perovskite-type manganites Sm0.35Nd0.35M0.3Mn1-xFexO 3 (M = Pb, Cd; x = 0, 0.1) have been synthesised and their magnetic and transport properties studied. Magnetic measurements show that TC values decrease considerably with the presence of cadmium or iron. Colossal magnetoresistance has been shifted to lower temperatures. Values of magnetoresistance near to 40% have been obtained. The presence of defined maxima in the real part of ac susceptibility at the same temperature of the cusp in the zero field cooling curves corroborates cluster-glass behaviour.2201425428Von Helmolt, R., Wecker, J., Holzapfel, B., Schultz, L., Samwer, K., (1993) Phys.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Influence of Fe in giant magnetoresistance ratio and magnetic properties of La[sub 0.7]Ca[sub 0.3]Mn[sub 1−x]Fe[sub x]O[sub 3] perovskite type compounds
No full textIn this work polycrystalline perovskite with composition La0.7Ca0.3Fe0.05Mn0.95O3 has been produced by standard ceramic method. A considerable change occurs in magnetic, transport and magnetoresistance properties with respect to the classic composition without Fe. The introduction of a different metal, Fe, in Mn-O layer causes a decrease of about 50 K in the value of T-C. In the same way, a decrease of about 10-15% in the average magnetic moment measured at 1 T is also observed. On the other hand, the introduction of Fe does not cause any appreciable change in the value of the lattice parameter. This new compound presents 60% of giant magnetoresistance ratio at 200 K. Magnetization vs. temperature measurements in zero field cooling and field cooling show clear differences at applied fields below 80 km(-1). Such a behavior, also observed in La0.7Ca0.3MnO3 sample, is not recognizable as a simple ferromagnetic one. A qualitative discussion of the effect in the magnetic and transport properties of these compounds, caused by the substitution of some Mn atoms by Fe is given
