This book was released on 2006 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: En nuestro país, 66.8% de la electricidad se genera actualmente en centrales termoeléctricas, y más de la mitad de estas centrales queman combustóleo, combustible residual que produce considerables emisiones de bióxido de azufre, óxidos de nitrógeno y partículas suspendidas. Si bien se prevé un papel creciente del gas natural en este sector, el combustóleo continuará utilizándose durante muchos años más en las termoeléctricas que se encuentran en operación. Por lo anterior, es necesario encontrar diversas formas de controlar y reducir las emisiones contaminantes provenientes del sector eléctrico nacional, como puede ser el uso de tecnologías de control de emisiones o de combustibles y procesos más limpios, a modo de hacer máximos los beneficios, en términos de reducción de emisiones, al menor costo posible. La selección de estas opciones requiere, pues, del análisis sistemático de los impactos de las emisiones contaminantes sobre la calidad del aire y en la salud de la población, así como de los beneficios relacionados con su control.

Deals also with persecution and segregation (e.g. the Jewish quarter, the yellow badge, taxation). Pp. 21-66 describe the pogroms of 1391 in Valencia and other towns, and subsequent conversion of the Jews. Ch. 5 (pp. 279-299), "The Expulsion of the Jews, " deals with the expulsion and spoliation of the Jewish population. Pp. 323-701 contain relevant documents in Latin and Catalan.
Download or read book The Protective Arm of the Renin Angiotensin System RAS written by Thomas Unger and published by Academic Press. This book was released on 2015-04-18 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Protective Arm of the Renin Angiotensin System: Functional Aspects and Therapeutic Implications is the first comprehensive publication to signal the protective role of a distinct part of the renin–angiotensin system (RAS), providing readers with early insight into a complex system which will become of major medical importance in the near future. Focusing on recent research, The Protective Arm of the Renin Angiotensin System presents a host of new experimental studies on specific components of the RAS, namely angiotensin AT2 receptors (AT2R), the angiotensin (1–7) peptide with its receptor Mas, and the enzyme ACE 2, which exert significant beneficial, health-promoting actions by counterbalancing the well-known harmful arm of the RAS with its classical angiotensin AT1 receptor. This innovative concept of the protective arm of the RAS, examined in this reference, represents an indispensable background and will be a strong support for biomedical students, researchers, cardiologists, surgeons, nephrologists, diabetologists, and endocrinologists, as well as any other physician or researcher concerned with RAS physiology, pathophysiology and clinical implications. Provides a complete understanding of the protective side of the Renin Angiotensin System (RAS) involving angiotensin AT2 receptor, ACE2, and Ang(1-7)/Mas receptor Combines the knowledge of editors who pioneered research on the protective renin angiotensin system including; Dr. Thomas Unger, one of the founders of AT2 receptor research; Dr. Ulrike M. Steckelings, who contributed significantly to first preclinical studies with a novel specific AT2-agonist, and Dr. Robson Santos who pioneered research on angiotensin-(1-7) and its receptor Mas. Shows that the protective RAS axes are able to ameliorate the course of several cardiovascular, renal, metabolic and neurological diseases Provides the basis for the understanding of a novel therapeutic approach to stimulate components of the protective arm of the RAS.
Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.
