The New York Times-bestselling "skeptical environmentalist" argues that panic over climate change is causing more harm than goodHurricanes batter our coasts. Wildfires rage across the American West. Glaciers collapse in the Artic. Politicians, activists, and the media espouse a common message: climate change is destroying the planet, and we must take drastic action immediately to stop it. Children panic about their future, and adults wonder if it is even ethical to bring new life into the world.Enough, argues bestselling author Bjorn Lomborg. Climate change is real, but it's not the apocalyptic threat that we've been told it is. Projections of Earth's imminent demise are based on bad science and even worse economics. In panic, world leaders have committed to wildly expensive but largely ineffective policies that hamper growth and crowd out more pressing investments in human capital, from immunization to education.False Alarm will convince you that everything you think about climate change is wrong -- and points the way toward making the world a vastly better, if slightly warmer, place for us all.

En esta obra se contempla la realidad de que vamos a tener que convivir con las resistencias bacterianas, creadas por el consumo de antibióticos, mantenidas por el consumo selectivo de determinados antibioticos y que generan la necesidad de nuevos antibioticos para superarlas. Nuestro pais presenta una situacion problematica respecto a las necesidades en los aislamientos prevalentes de las infecciones respiratorias.Ante la duda de que una restriccion no selectiva del antibiotico invierta la evolucion de las resistencias hasta el punto de producir su decremento, la inclusion de nuevos antibioticos en el arsenal terapeutico es bienvenida en este ambiente epidemiologico.Por otra parte, este mismo ambiente epidemiologico y la infraestructura sanitaria, incluyendo los Departamentos de Microbiologia, que son los que detectan las resistencias, hacen a nuestro pais adecuado para el desarrollo clinico de estos antimicrobianos, asi como para la realizacion de estudios que marquen las diferencias entre ellos.

With the diverse teaching backgrounds of first year university students, the highly detailed traditional organic chemistry textbook does not provide an easily digestible presentation of the very basic information required by many students to begin their study of this exciting subject. Based on the highly successful and student friendly ''at a glance'' approach, with integrated, self contained double page spreads of text and graphics, "Organic Chemistry at a Glance" provides concise organic chemistry notes for students studying chemistry and related courses at undergraduate level.Graphical presentation of information is central to this book and facilitates the rapid assimilation and understanding of the basic concepts, principles and definitions of organic chemistry. It is not intended to replace existing organic chemistry textbooks, but to provide a tool with which the student can quickly, economically and confidently acquire, regularly review and revise the basic facts that underpin organic chemistry.
