BOOK REVIEW OF LIFE OF PI BY YANN MARTEL

This book review is written to find the strength and the weakness in Life of Piwhich is written by Yann Martel. “The Book Review of Life of Pi” is focusing on the content of the novel finding the strength and the weakness. The strengths are the plot and the main character named Pi, the weakness is the end of the novel. The plot conveys how the author describes all situations in this novel clearly and the main character shares readers about how to face the world and Pi shares lots of values in his life as a tough boy. The weakness is the end of the novel, Martel does not give an explanation about why Richard dumps Pi without saying goodbye at all. This novel conveys about anything that people think. A novel does not deliver any knowledge of life, but in this novel I read many valuable words

Cerros, nevados y páramos: un intento de arqueología etnográfica

Considering a cross perspective among archaeology, ethnohistory and ethnography, this paper aspire to rebuilding the relationship between prehispanic cultures and the cosmos, specially from the sacrality of mountains and huacas. Thus, revisiting their own fieldworks in the Ecuadorian sierra, the author try to revitalizing the importance of historical contexts in the perception of this cosmic relations, tracking the ideological continuities which speak about the mountains as dangerous spaces where different forms of alterity live

The skyrmion-bubble transition in a ferromagnetic thin film

Magnetic skyrmions and bubbles, observed in ferromagnetic thin films with perpendicular magnetic anisotropy, are topological solitons which differ by their characteristic size and the balance in the energies at the origin of their stabilisation. However, these two spin textures have the same topology and a continuous transformation between them is allowed. In the present work, we derive an analytical model to explore the skyrmion-bubble transition. We evidence a region in the parameter space where both topological soliton solutions coexist and close to which transformations between skyrmion and bubbles are observed as a function of the magnetic field. Above a critical point, at which the energy barrier separating both solutions vanishes, only one topological soliton solution remains, which size can be continuously tuned from micrometer to nanometer with applied magnetic field

Anisotropic magneto-Coulomb effect versus spin accumulation in a ferromagnetic single-electron device

We investigate the magneto-transport characteristics of nanospintronics single-electron devices. The devices consist of single non-magnetic nano-objects (nanometer size nanoparticles of Al or Cu) connected to Co ferromagnetic leads. The comparison with simulations allows us attribute the observed magnetoresistance to either spin accumulation or anisotropic magneto-Coulomb effect (AMC), two effects with very different origins. The fact that the two effects are observed in similar samples demonstrates that a careful analysis of Coulomb blockade and magnetoresistance behaviors is necessary in order to discriminate them in magnetic single-electron devices. As a tool for further studies, we propose a simple way to determine if spin transport or AMC effect dominates from the Coulomb blockade I-V curves of the spintronics device

BASTIAN (Jean-Pierre), GUICHARD (François), MESSIANT (Christine), Des protestantismes en « lusophonie catholique », suivi de Les Protestantismes dans la cartographie religieuse au Brésil de Philippe Waniez et Violette Brunstein

Spécialisée dans le monde lusophone, la revue Lusotopie présente un important dossier en deux parties (dont la seconde devait paraître en 1999) sur les protestantismes dans les pays lusophones (Brésil, Portugal, Angola, Sao Tomé, Mozambique) dont l’avantage est d’offrir une vue comparative des différents courants englobés dans le terme générique de « protestantisme ». Ces espaces ont en commun une histoire, marquée par les migrations et la culture portugaises, et une langue de communication, ..

La marginación de Hispanoamérica por la Historia universal europea (siglos XVIII-XIX)

Universal History, as an academic discipline, is born in Europe (England, France and German principalities) as an attempt to place European development at the center of reflection, contrasting it with other temporalities. Returning to the old debate on AmLa Historia Universal, como disciplina académica, nace en Europa (Inglaterra, Francia y principados alemanes) como un intento de situar en el centro de la reflexión el desarrollo europeo, contrastándolo con otras temporalidades. Retomando el viejo debat

Erwan Dianteill (Coord.), Marcel Mauss. L’anthropologie de l’un et du multiple

Fondateur de l’anthropologie française, Marcel Mauss a fait l’objet d’un grand nombre d’études suscitées à la fois par le caractère inachevé de ses textes, qui s’ouvrent à différentes interprétations, et par la richesse des informations ethnographiques sur des sociétés primitives (acceptons ici ce terme) qu’il met en rapport avec la modernité. Le sous-titre de ce livre, l’un et le multiple, traduit bien le projet maussien d’étudier l’Homme sous toutes ses variantes culturelles. Ce livre regro..
