Scientific research on cold-adapted microorganisms (specifically polar microbes) is of great interest, since Arctic and Antarctic regions harbor diverse and active populations of microorganisms. However, these microorganisms are subject to impacts of environmental perturbations. For example, climate change will modulate the distribution and activity of many cyanobacteria and algal species in polar environments that contribute significantly to global carbon fixation and oxygen production. Moreover, many microorganisms that have remained frozen for thousands of years can revive their metabolic activity and re-join the modern microbial community. For survival in freezing environments, polar mic...

Nélida, la joven hija de un rico hacendado argentino, de vacaciones con su familia en la Costa Azul, huye de su familia en compañía de Auguste Lamartine, el músico que ameniza las tardes de lluvia a la selecta clientela del Gran Hotel de Niza, a esa Viena de principios del siglo XX, donde la alta sociedad vive y se divierte en la protocolaria corte del viejo emperador Francisco José y su íntima Katharina Schratt. El posterior abandono por parte del músico, y el estallido de la Gran Guerra, rompen el ritmo de esa sociedad y las murallas interiores de la frágil e inexperta Nélida. A punto de morir de inanición es rescatada de una cola de hambrientos por un oficial que vuelve de la gu...
This book constitutes the refereed proceedings of the 10th International Work-Conference on Artificial Neural Networks, IWANN 2009, held in Salamanca, Spain in June 2009. The 167 revised full papers presented together with 3 invited lectures were carefully reviewed and selected from over 230 submissions. The papers are organized in thematic sections on theoretical foundations and models; learning and adaptation; self-organizing networks, methods and applications; fuzzy systems; evolutionary computation and genetic algoritms; pattern recognition; formal languages in linguistics; agents and multi-agent on intelligent systems; brain-computer interfaces (bci); multiobjetive optimization; robotics; bioinformatics; biomedical applications; ambient assisted living (aal) and ambient intelligence (ai); other applications.
