Las sendas del desencanto: Los mares del sur de Manuel Vazquez Montalban

Manuel Vazquez Montalban (Barcelona 1939-Bangkok 2003), uno de los escritores espanoles contemporaneos mas prolificos, es conocido no solamente por sus obras literarias sino tambien por su ideologia politica de izquierda y por su entonces aguda critica a la incipiente sociedad democratica espanola de los setenta y ochenta. Escribio quince novelas detectivescas entre 1972 y 2000 que tienen como protagonista a Pepe Carvalho, un detective privado al que Ie gusta la comida gourmet y sieve como un alter ego de Montalban-escritor-intelectual de izquierda y anti-franquista declarado. La cuarta novela de esta serie, Los mares del Sur (1979) que gano el Premio Planeta en 1979, trata fundamentalmente de las maneras de escapar de las dificultades de la transicion espanola

Degradation of Phosphorene in Air: Understanding at Atomic Level

Phosphorene is a promising two dimensional (2D) material with a direct band gap, high carrier mobility, and anisotropic electronic properties. Phosphorene-based electronic devices, however, are found to degrade upon exposure to air. In this paper, we provide an atomic level understanding of stability of phosphorene in terms of its interaction with O2 and H2O. The results based on density functional theory together with first principles molecular dynamics calculations show that O2 could spontaneously dissociate on phosphorene at room temperature. H2O will not strongly interact with pristine phosphorene, however, an exothermic reaction could occur if phosphorene is first oxidized. The pathway of oxidation first followed by exothermic reaction with water is the most likely route for the chemical degradation of the phosphorene-based devices in air

Free your budget, Free your mind: Free Online Web Conference Solutions

Library budgets are feeling the effects of the economic downturn, and librarians have to be creative in order to meet the collaborative needs of faculty and students. Not all libraries can afford licenses for higher-end videoconferencing software packages such as Adobe Connect or Cisco WebEx, despite their importance in serving distance education students and facilitating faculty collaborations. But with all the free alternatives available, how do you decide what s worth it? The presenters evaluated free programs that offer voice, chat, and screensharing capacities; they are also cross-platform and entirely free of charge. These programs have applications both for reaching distance education students and for professional development. Advantages and disadvantages of several programs will be presented. Although it is said that you get what you pay for, free web conference software can offer rewards far beyond its time and space initial investment. ABOUT THE PRESENTERS: Vicki Gruzynski is the Information Services Librarian at Southeast Missouri State University\u27 Kent Library; Rachel Slough is the E-Learning Librarian at Murphy Library, University of Wisconsin-La Crosse

Rapid Multiplexed Data Acquisition: Application To Three-Dimensional Magnetic Field Measurements In A Turbulent Laboratory Plasma

Multiplexing electronics have been constructed to reduce the cost of high-speed data acquisition at the Swarthmore Spheromak Experiment (SSX) and Redmond Plasma Physics Laboratory. An application of the system is described for a three-dimensional magnetic probe array designed to resolve magnetohydrodynamic time scale and ion inertial spatial scale structure of magnetic reconnection in a laboratory plasma at SSX. Multiplexing at 10 MHz compresses 600 pick-up coil signals in the magnetic probe array into 75 digitizer channels. An external master timing system maintains synchronization of the multiplexers and digitizers. The complete system, calibrated and tested with Helmholtz, line current, and magnetofluid fields, reads out the entire 5 x 5 x 8 probe array every 800 ns with an absolute accuracy of approximately 20 G, limited mainly by bit error.
