Los pequenos gigantes del planeta, la esperanza es un libro especialmente para los ninos que, al leerselos sus papas o mamas, les ensenaran los valores que en estos dias las generaciones que estan naciendo los estan perdiendo. Este libro esta enfocado, principalmente, a los ninos de esta nueva generacion de todo el mundo. Ademas, a la vez es un hermoso cuento que parece de fantasia, pero es la realidad de las cosas que estan pasando en el Planeta Tierra. Tambien esta compuesto por versos y poesias, que a la vez, todo lo narrado en el libro es real y veridico en la mente del autor.

Rock breakage with explosives has existed since the seventeenth century when black powder came into use in mining. Since then it has progressed from the invention of dynamite to the use of heavy ANFO. During the past two decades, there have been numerous technical contributions which have brought a better understanding of rock fragmentation with explosives, an improvement in drilling equipment and a noticeable evolution in the development of new explosives and blasting accessories. The Geomining Technological Institute of Spain (ITCE), aware of this progress and of the importance which the breakage process has acquired in mining and civil engineering projects, has ordered the publication of ...
In this new history, David Edgerton invites us to rethink how technology is used. For instance, horses contributed more to Nazi conquests than the V2. In influence, IKEA founder Ingvar Kamprad matches Bill Gates. And corrugated iron is not dead yet.
El importante número de canciones compuestas sobre los poemas de José Agustín Goytisolo evidencia las innegables cualidades líricas de una buena parte de la producción poética de este autor, uno de los más queridos y respetados de cuantos han dado las letras españolas en la segunda mitad del siglo xx.

En paralelo, se exploran –a partir sobre to...
This book contains the papers presented at the XXXI International Congress INGEGRAF “Graphic Expression: reunion, reflection, representation,” held on June 29–30 and July 1, 2021, in Málaga, Spain. It reports on cutting-edge topics in product design and manufacturing, such as industrial methods for integrated product and process design, innovative design and computer-aided design. Further topics covered include virtual simulation and reverse engineering, additive manufacturing, product manufacturing,engineering methods in medicine and education, representation techniques and nautical, engineering and construction, aeronautics and aerospace design and modeling. The book is divided into six main sections, reflecting the focus and primary themes of the conference. The contributions presented here provide researchers, engineers and experts in a range of industrial engineering subfields with extensive information to support their daily work; but also they are intended to stimulate new research directions, advanced applications of the methods discussed and future interdisciplinary collaborations.
