In this book, Tal Ben-Shahar introduces a new interdisciplinary field of study that is dedicated to exploring happiness. The study of happiness ought not be left to psychologists alone. Philosophers, theologians, biologists, economists, and scholars from other disciplines have explored ways of attaining happiness, and to do justice to this important pursuit, we ought to listen to their words and experiment with their prescriptions. Not only does the field of happiness studies embrace different disciplines, it also approaches happiness as a multifaceted and multidimensional variable that includes five parts which form the acronym SPIRE:Spiritual wellbeingPhysical wellbeingIntellectual wellbeingRelational wellbeingEmotional wellbeingThis book addresses each of these elements of happiness, explains them, and addresses practical ways for their cultivation.

An excellent, concise, and interdisciplinary overview of different classes of emerging pollutants arising, for example, from pharmaceuticals, pesticides, personal care products, and industrial chemicals and their impact on water, soil, and air. Following an introduction to chemical pollutants, with special attention focused on organic compounds and their properties, the book goes on to describe major emerging pollutants grouped according to their applications in different sectors of industrial or economic activity. For each type of compound, the chemical structure, main properties, and source are presented, along with their fate in the environment as pollutants, the latest analytical methods for detection, possible health or ecology consequences, as well as current regulatory laws. New developments, such as nanotechnology as a pollution source, are also included. The book closes with a chapter devoted to conclusions and future perspectives.

Advances in Sustainable Applications of Microalgae discusses different mechanisms used by microalgae to treat various gaseous streams wastewaters and pollution bioremediation In addition the advantages of the application of microalgal biomass in the agricultural and food feed sectors are presented and bioenergy from microalgae with a view to sustainability is explored The present covers the use of microalgal cultures in various applications such as the treatment of gaseous streams by removing various contaminants wastewater treatment through the removal of several pollutants biomass valorization for agriculture purposes bioenergy from microalgae and industrial integration of all these processes in a biorefinery concept Finally the book emphasizes the importance of gathering scientific knowledge to overcome drawbacks related to microalgal production and develops the concept of biorefinery based on microalgal biomass for a more sustainable future

Steven Weinberg, premio Nobel de Física por su contribución a la unificación de dos de las fuerzas básicas de la naturaleza -la fuerza débil y el electromagnetismo-, aborda en este libro la gran aventura intelectual de nuestro tiempo: la busqueda de una teoria final, aquella en la que todas las preguntas fundamentales hallarian respuesta sin requerir una explicacion en terminos de otros principios. Weinberg, que no solo es un gran fisico sino un excelente divulgador, nos explica de manera llana y comprensible la idea de esta teoria final, los pasos que han conducido hacia ella ylos obstaculos que encuentra, dejandonos en la frontera de esa tierra prometida.

Durante eones, las mentes más grandes de la humanidad han carecido de respuestas confirmables a las preguntas que definen y explican el significado de la existencia humana: qué somos y qué nos creó. En Genesis, el celebre biologo Edward O. Wilson examina la historia evolutiva y nos ofrece una descripcion reveladora de los profundos origenes de la sociedad. Al afirmar que las creencias religiosas y las cuestiones filosoficas se pueden reducir a componentes puramente geneticos y evolutivos, y que tanto el cuerpo como la mente humanos poseen una base fisica que obedece a las leyes de la fisica y la quimica, Genesis demuestra que el unico modo que tenemos para comprender el comportamiento humano es estudiar las diversas historias evolutivas de las especies no humanas.Wilson demuestra que se han observado al menos diecisiete (entre ellas la rata topo desnuda africana y el camaron que deja sus huevos en una esponja) que han desarrollado sociedades avanzadas basadas en niveles de altruismo y la cooperacion parecidos a los humanos. Ya sea escribiendo sobre dipteros que bailan como acrobatas o bancos de anchoas que se apiñan como medida de proteccion para parecer un pez gigantesco, Edward O. Wilson elabora una obra innovadora sobre la teoria evolutiva con las observaciones biologicas y humanisticas por las que es conocido y admirado.
