The 'golden age' for antibiotic discovery, from 1940 until the early 1970s, ushered in a new era in human- and animal-health and the associated dramatic increase in human life expectancies. Indeed the possibility of eradicating infectious disease seemed feasible. However it soon became apparent that microorganisms wouldn't be defeated so easily. Their weapon: antibiotic resistance. Today microbial antibiotic resistance is rapidly exhausting our supply of effective compounds and making the possibility of a global public health disaster seems likely. The urgency of this situation has spawned a plethora of new multi-disciplinary research initiatives looking for novel antibiotics and other antimicrobial agents. In this timely book respected international experts summarize the most important research to provide a timely overview of the field. Opening chapters define 'antibiotic', explain why we need new compounds, outline the applications of antibiotics, both old and new, and describe the producing microbes. These are followed by chapters that cover antibiotic resistance, toxicity, overuse, new antimicrobial sources, new targets, novel technologies for antibiotic discovery (e.g. silent gene clusters), lantibiotics, natural antivirals, new macrolide derivatives, and antibiotics in the pipeline. This books is essential reading for everyone working in antimicrobial research in academia, biotechnology companies, and the pharmaceutical industry and a recommended volume for all microbiology libraries.

The papers in this volume give the reader focused information on the important extractive metallurgy unit operations of drying, roasting, and calcining

Bringing together international case studies, this book offers theoretical and empirical insights into the interaction between social work and social policy. Moving beyond existing studies on policy practice, the book employs the policy cycle as a core analytical frame and focuses on the influence of social work(ers) in the problem definition, agenda setting, policy formulation and implementation of social policy. Twenty-three contributors offer examples of policy making from seven different countries and demonstrate how social work practitioners can become political actors, while also encouraging policy makers to become aware of the potential of social work for the social policy-making process.

"Pasaporte a Ovnilandia" es el primer libro del abogado y criminologo chileno Sergio Sanchez R. Publicado originalmente en 1999, supuso en su momento una sorpresa en el reducido mercado editorial de Chile y un acierto por su abordaje teorico de la historia de las especulaciones ufologicas. Por su caracter unico y su valor historico, Coliseo Sentosa se complace de realizar la edicion por el 20 aniversario de una obra indispensable.

"Erase una vez en Ovnilandia" ofrece una historia del desarrollo de la ufologia en Francia, desde sus origenes en los anos cincuenta hasta nuestros dias. Concretamente, se trata de una historia de las hipotesis, especulaciones y debates teoricos que han marcado la saga ovnistica francesa, y que le han dado un sello particular y caracteristico, tan distinto del que viene siempre asociado a la ufologia estadounidense, con sus platillos volantes estrellados y sus conspiraciones infinitas. Este segundo volumen, homonimo de un articulo de Jean Giraud, de 1977, trata de la evolucion de la paraufologia o ufologia parafisica, de las tesis marginales y, por cierto, de las dimensiones sociales y religiosas del "contactismo".
