Dicen que el mejor amigo del hombre es el perro, pero seguro que los primeros que lo domesticaron ya comían vegetales, utilizaban sus fibras para vestirse o quemaban madera para calentarse; desde el principio hemos sabido sacar provecho a las plantas y encontrar sus multiples aplicaciones. En un viaje por el cuerpo humano, conoceremos las fascinantes historias que hay detras, descubriremos plantas que ayudan al corazon, que nos calman el dolor, que regulan el ciclo menstrual o algunas que incluso se usan para sintetizar medicamentos contra el cancer. Un recorrido apasionante en el que, con el rigor cientifico y la cercania de Rosa Porcel, @bioamara, veremos como la humanidad ha ido aprendiendo para que sirven, y lo mas importante, para lo que no sirven, hasta llegar a la actualidad, donde gracias a la ciencia hemos logrado avances extraordinarios.Leyendo este libro entenderas por que, y desde hace mucho tiempo, el mejor amigo del hombre siempre ha sido la planta.

Con esta publicación en torno a la ordenación del territorio, el urbanismo y el medio ambiente, FUNDICOT (Asociación interprofesional de Ordenación del Territorio) tiene el objetivo de contribuir al avance en el debate y las propuestas sobre el presente y el futuro de estas importantes areas de actuacion publica para el bienestar de la sociedad y del planeta. Con ello se pretende seguir teniendo un papel propositivo entre los actores -publicos y privados- implicados en estas materias; tambien, poder acumular mas informacion, conocimiento y concienciacion social para desarrollar una adecuada cultura territorial. Y todo ello en un contexto cada vez mas complejo e incierto debido a los efectos del calentamiento global y a la critica situacion geopolitica a nivel internacional, factores que incrementan los niveles de riesgo y hacen que esta tarea sea mas necesaria.

An overview of increasingly indispensable radiometric technologiesMicrowave radiometers have become a central part of Earth observation and radioastronomy. Most existing reference works on the subject, however, largely omit two key types of radiometers: interferometric radiometers and polarimetric radiometers. The extensive applications of these two classes of radiometer and their potential for mapping distant celestial bodies and enhancing Earth observation has made it critical for the next generation of radiometric scientists and engineers to be familiar with this technology and its principles.Principles of Interferometric and Polarimetric Radiometry meets this crucial need with a first-in-class overview of this key subject. Beginning with an introduction to the foundational concepts of microwave radiometry, it proceeds to work through a careful revision of the fields major theory and techniques, with a particular emphasis on interferometric and polarimetric systems. The result promises to revolutionize the use of microwave passive sensors for Earth observation and beyond.

Water is the essential substance for life on Earth The natural patrimony of all living beings and the material and cultural heritage a common good a shared resource a treasure trove of humanity The nature of water water at rest and in motion the water cycle and its management are addressed here in a multidimensional comprehensive and transdisciplinary approach The book focuses on water without complying with any disciplinary approach philosophical historical physical and mathematical issues are merged with traditional hydrochemistry hydrostatics hydrodynamics and hydrology to provide an overview of basic knowledge on Earth s water These five lectures can be delivered to any undergraduate STEM student to introduce them a valuable basic multidisciplinary knowledge on water Non specialists will find here an insight of water made as simple as possible but not simpler than required

Aunque el término «ecología» es reciente, las preocupaciones ambientales y la regulación de las relaciones con la naturaleza estuvieron muy presentes en la Antigüedad. Si bien la naturaleza se presen

La protagonista de las cinco historias que cuentan las páginas de este libro es la Química. Los cinco relatos ( El descubrimiento de Annika , Los dos caminos , Fernando y su historia de vida , El ajuste de cuentas y Frisquiman ), nos dan buena cuenta de este mundo fascinante. Sus historias nos hablan de la Quimica desde diferentes perspectivas: sus aplicaciones mas cotidianas, su irrupcion en momentos historicos clave, o su enseñanza en las aulas, y todo ello con un objetivo: despertar el interes por la ciencia de los jovenes lectores.

For students and practitioners, a comprehensive primer on the key literature in stream and river ecology. The study of streams and rivers combines ecology, chemistry, hydrology, and geology to reveal the factors that control the biological diversity and functioning of these unique ecosystems. Although stream ecology is a relatively young discipline, foundational papers published over the past half century have shaped our current understanding of these ecosystems and have informed our efforts to manage and protect them. Organized by topics such as the physical template, community structure, food webs, ecosystem energetics, and nutrient dynamics, the chapters of this book offer summaries of the key literature, historical and contextual information, and insightful discussions of how past research has influenced present studies and may shape future work.
