This book assesses the use of various non-seismic and non-conventional oil and gas exploration methods in Cuba. In addition to discussing the benefits of these methods, the book demonstrates how they can be combined with geological data and conventional methods, leading to a better evaluation of prospects and exploration risks. The authors describe how potential new gaso-petroleum sites in the Pina-Ceballos and Sancti Spiritus regions can be effectively mapped. The geophysical-geochemical exploration techniques combined in the Redox Complex method are used to identify and evaluate these sites. Areas of interest are mapped based on the presence of a combination of indicator anomalies, mainly derived using gravimetric, aeromagnetic and airborne gamma spectrometry. The geochemical study concentrates on two petroleum-rich regions, one in northern and one in southern Cuba. The scope also includes the seas to the south of Cuba, which are studied with non-seismic exploration tools such as the Digital Elevation Model, which employs morphotectonic regionalization.
The so-called "Non-conventional geophysical-geochemical exploration methods" are used, in the particular case of oil and gas exploration, for the detection and mapping of active microseepage of light hydrocarbons with a vertical nature on the gas-oil accumulations. The non-seismic exploration methods used in Cuba are: Remote Sensing, Gravimetry, Aeromagnetometry, Airborne Gamma Spectrometry (AGS) and Morphometry (non-conventional, from the Digital Elevation Model 90x90m). The AGS also classifies, as a non-conventional geophysical-geochemical method, together with the Redox Complex. Besides, it is of interest to know the geological-structural framework where these microseepage occur. That is ...

The evolution of geological cartography in Cuba in its more than 135 years of history has been possible through the consultation of numerous archival reports, publications, maps and personal interviews with different authors and geologists of vast experience. A brief critical analysis is made of the increase in the degree of geological knowledge of the country since the elaboration of the Geological Sketch of the Cuban Island at a scale of 1: 2 000 000 (Fernández de Castro, 1883), first of Cuba and of Ibero-America, until the most recent Digital Geological Map of Cuba at scale 1: 100 000 (Pérez Aragón, 2016). Cuba and its surroundings are a geological mosaic in the southeast corner of the...
Fungi play vital roles in all ecosystems, as decomposers, symbionts of animals and plants and as parasites. Thus their ecology is of great interest. It has been estimated that there may be as many as 1. 5 million species of fungi, many of which are still undescribed. These interact in various ways with their hosts, with their substrates, with their competitors (including other fungi) and with abiotic variables of their environment. They show great variation in morphology, reproduction, life cycles and modes of dispersal. They grow in almost every conceivable habitat where organic carbon is available: on rock surfaces, in soil, the sea and in fresh water, at extremes of high and low temperatu...
The International Chess Federation or FIDE (from the French Federation Internationale des Echecs) was founded in Paris in 1924 but only from 1950 began to award international titles. This book lists more than 18,000 players who received titles from 1950 through 2016. Entries include (where available) the player's full name, federation, date of birth, place of birth, date of death, place of death, title and year of award and peak rating (month and year), with references provided.
This volume examines the global influence and impact of DIY cultural practice as this informs the production, performance and consumption of underground music in different parts of the world. The book brings together a series of original studies of DIY musical activities in Europe, North and South America, Asia and Oceania. The chapters combine insights from established academic writers with the work of younger scholars, some of whom are directly engaged in contemporary underground music scenes. The book begins by revisiting and re-evaluating key themes and issues that have been used in studying the cultural meaning of alternative and underground music scenes, notably aspects of space, place...
Numerosas pruebas empiricas han puesto de manifiesto que la intensificacion sostenible de la produccion agricola es tecnicamente posible y economicamente rentable, y que brinda beneficios adicionales como el mejoramiento de la calidad de los recursos naturales y la proteccion del ambiente en zonas actualmente no mejoradas o degradadas, siempre que los agricultores participen en todas las etapas del desarrollo y extension de la tecnologia. Este tipo de agricultura, llamada de conservacion, se caracteriza por la eliminacion del disturbio mecanico del suelo, por una cobertura permanente del suelo y por la rotacion de los cultivos. Estos tres elementos distinguen la agricultura de conservacion de los sistemas agricolas convencionales. El proposito de esta publicacion es demostrar como esta agricultura incrementa la produccion y al mismo tiempo reduce la erosion y revierte el proceso de disminucion de la fertilidad del suelo; mejora las condiciones de vida de la poblacion rural y restaura el ambiente en los paises en desarrollo. El estudio se basa en testimonios y experiencias de agricultores y extensionistas en America Latina y en Africa."
More than any other sport, baseball has developed its own niche in America's culture and psyche. Some researchers spend years on detailed statistical analyses of minute parts of the game, while others wax poetic about its players and plays. Many trace the beginnings of the civil rights movement in part to the Major Leagues' decision to integrate, and the words and phrases of the game (for example, pinch-hitter and out in left field) have become common in our everyday language. From AARON, HENRY onward, this book covers all of what might be called the cultural aspects of baseball (as opposed to the number-rich statistical information so widely available elsewhere). Biographical sketches of al...
