This book was released on 2021-03-31 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: El campo eléctrico constituye la base para cualquier análisis de los procesos que se desarrollan en un medio dieléctrico y, como consecuencia, para todos los cálculos sobre el comportamiento de los dieléctricos. En el caso de las instalaciones de baja tensión se procura que el aislamiento posea una resistencia suficiente, que el material no va de química ni físicamente con el tiempo y que para determinados casos, posea una resistencia mecánica suficiente. Para aislamientos de alta tensión se procuran satisfacer dichas condiciones, pero es necesario, además, evitar que el aislante sea destruido por el fuerte campo eléctrico, es decir, que se produjera a su través alguna descarga o perforación en importancia de campo eléctrico no que circunscripta, sin embargo, al caso de los aislantes, pues la energía en él almacenada influye en todas las variaciones de intensidad y de tensión de las corrientes que circulan entre los límites del campo, y esto en tanto maym escala cuanto más extensa sea la instalación. De estas breves consideraciones surge la importancia del campo eléctrico en alta tensión. UNIVERSITAS EDITORIAL CIENTÍFICA UNIVERSITARIA DE CÓRDOBA ARGENTINA.

Book excerpt: In a universe protected by the Three Laws of Robotics, humans are safe. The First Law states, A robot may not injure a human being, or, through inaction, allow a human being to come to harm. When an experiment with a new type of robot brain goes awry, the unthinkable happens. Caliban is created... A robot without guilt or conscience. A robot with no knowledge of or compassion for humanity. A robot without the Three Laws. Caliban is a searing examination of Asimov's Three Laws of Robotics, a challenge welcomed and sanctioned by Isaac Asimov, the late beloved genius of science fiction, and written with his cooperation by one of today's hottest talents, Roger MacBride Allen, New York Times bestselling author of Ambush at Corella, The Modular Man, and The Ring of Charon.

Available in PDF, EPUB and Kindle. Book excerpt: Appeals to a Wide Audience Fueled by more than 30 years of intensive research and debate on the impact of electromagnetic fields (EMF) on everyday life—starting with residential exposure to magnetic fields and the development of childhood cancer in the 70s and continuing with risk of exposure via wireless communications in present day—Epidemiology of Electromagnetic Fields addresses ongoing public and scientific controversy surrounding the possible effects of electromagnetic fields (EMF) to human health, and provides an in-depth introduction into the methodology of environmental epidemiology that is appropriate for all levels, from student to practicing engineer. Exposure to EMF Focusing primarily on EMF examples, the author presents the general principles and methodological concepts in environmental epidemiology. Topics of importance in the first part of the book include epidemiological study designs, exposure assessment methods and implications for the study results, as well as selection bias, confounding, and other biases including reverse causality and ecological fallacy. The second part of the book covers environmental epidemiological methods in detail and outlines key examples such as childhood leukemia and exposure to extremely low-frequency magnetic fields, as well as examples that look at brain tumors and mobile phone use. The book also offers a detailed discussion on the range of EMF sources and exposures. In addition, it highlights the sophisticated assessment methods required to address exposure situations, and provides a historical perspective. The third part of the book examines how EMF exposure from the use of wireless communication techniques and other challenges affect risk assessment today and also details future developments. Explores environmental epidemiological methods in detail, while critically discussing epidemiological findings Provides a state-of-the-art overview of the scientific evidence of the health effects of EMF Considers how novelty, the steep increase of radiofrequency (RF) EMF exposure from wireless communications, and other challenges affect risk assessment today Epidemiology of Electromagnetic Fields provides a thorough overview of the subject, and evaluates the scientific evidence surrounding the possible health effects of EMFs.

Book excerpt: This vivid exposé of corruption and political tyranny in the Dominican Republic rang so true to the reality that the President of that country went on television to denounce the book. Sención's novel follows the lives of three seminary students who suffer from church-state oppression. The book also gives a chilling portrait of Dr. Ramos, a sinister autocrat, who manages to survive six terms as president of his country through manipulation and tyranny.
