La práctica actividad física muestra innumerables beneficios para la salud. Sin embargo, desde hace años, la población adolescente española es cada vez menos activa y todo apunta a que este incremento de la inactividad es más fuerte en el género femenino. En este sentido, algunas de nuestras investigaciones previas han indicado que este fenómeno se está produciendo de forma cada vez más preocupante en la localidad y provincia de Huelva, donde el número de chicas adolescentes que son físicamente activas fuera del centro escolar desciende dramáticamente con respecto a etapas anteriores. En muchos casos, la Educación Física (EF) es la principal experiencia motriz de los/as estudi...
Nearly two decades into the new millennium, Latin American documentary film is experiencing renewed vibrancy and visibility on the global stage. While elements of the combative, politicized cinema of the 1960s and 1970s remain, the region’s production has become increasingly subjective, reflexive, and experimental, though perhaps no less political. At the same time, Latin American filmmakers both respond to and shape global tendencies in the genre. This book highlights the richness and heterogeneity of Latin American documentary film, surveys a broad range of national contexts, styles, and practices, and expands current debates on the genre. Thematic sections address the “subjective turn” of the 1990s and 2000s and the move beyond it; the ethics of the encounter between the filmmaker and the subject/object of his or her gaze; and the performance of truth and memory, a particularly urgent topic as Latin American countries have transitioned from dictatorship to democracy.
In vitro fertilization has resulted in an estimated 4000-5000 births in the world. The procedure has been accepted in Europe, America and Australia and several hundred IVF clinics are operating successfully. The newer procedures of GIFf, embryo freezing and donor oocyte IVF have become established and are dealt with in several chapters. GIFf has become the procedure of choice for patients with infertility of unknown origin. Oocyte freezing represents an important new technology which is being developed. The routine IVF procedure has improved slightly; variation in results can be reduced by quality control of laboratory and clinical techniques. Male factor infertility has been dealt with by I...
In January of 2015, under the 1st International Caparica Conference in Antibiotic Resistance, a Research Topic entitled: “Surveying Antimicrobial Resistance: Approaches, Issues, and Challenges to overcome”, was published (http://journal.frontiersin.org/researchtopic/3763/surveying-antimicrobial-resistanceapproaches- issues-and-challenges-to-overcome). The problem of antimicrobial resistance (AMR), caused by excessive and inappropriate use of antibiotics, is a public health issue that concerns us all. The introduction of penicillin in the 1940s, the start of the antibiotics era, has been recognized as one of the greatest advances in therapeutic medicine. However, according to the World He...
The Routledge Handbook of Forest Ecology is an essential resource covering all aspects of forest ecology from a global perspective. This new edition has been fully revised and updated throughout to reflect the profound and unprecedented changes in both forests and climates since the publication of the first edition in 2015. The handbook reflects key developments in the field of forest dynamics and large-scale processes, as well as the changes that are now manifesting in different types of forests across the globe as a result of climate change. It covers both natural and managed forests, from boreal, temperate, sub-tropical and tropical regions of the world. In this second edition, the breadt...

Based on archival research, this study of Pancho Villa aims to separate myth from history. It looks at Villa's early life as an outlaw and his emergence as a national leader, and at the special considerations that transformed the state of Chihuahua into a leading centre of revolution.
Tezcatlipoca: Trickster and Supreme Deity brings archaeological evidence into the body of scholarship on “the lord of the smoking mirror,” one of the most important Aztec deities. While iconographic and textual resources from sixteenth-century chroniclers and codices have contributed greatly to the understanding of Aztec religious beliefs and practices, contributors to this volume demonstrate the diverse ways material evidence expands on these traditional sources. The interlocking complexities of Tezcatlipoca’s nature, multiple roles, and metaphorical attributes illustrate the extent to which his influence penetrated Aztec belief and social action across all levels of late Postclassic central Mexican culture. Tezcatlipoca examines the results of archaeological investigations—objects like obsidian mirrors, gold, bells, public stone monuments, and even a mosaic skull—and reveals new insights into the supreme deity of the Aztec pantheon and his role in Aztec culture.
This book fills the gap between fundamental and applied research in the use of nanomaterials in biomedical applications, covering the most relevant areas, such as the fundamental concepts of the preparation of nanostructures and regulatory requirements for their safe use in biomedical devices. It also critically discusses what has been achieved in the field, and what needs to be urgently addressed and reviews the state-of-the-art medical uses of nanomaterials for treating damaged organs and tissues. Combining the expertise of clinical researchers working in the field of tissue engineering and novel materials, the book explores the main topics regarding the characterization of materials, spec...
