Available in PDF, EPUB and Kindle. Book excerpt: Este libro ha sido desarrollado como una guía sencilla para la elaboración de prácticas de suelo, tanto en campo como en laboratorio, usando métodos simples con los que se puede prescindir de espacios especializados para estos análisis. El autor no pretende impartir cátedra sobre el estricto quehacer del estudio del suelo, el cual es imposible abarcar en una obra pequeña como esta, sino contribuir mediante prácticas sencillas, al conocimiento y comprensión de algunas de sus características, que tienen relación con los aspectos ambientales y las dinámicas ecosistémicas que se abordan desde la óptica de las ciencias ambientales, la agronomía o la ingeniería, entre otras. El autor ha incluido un gran número de imágenes que pretenden recrear, además del desarrollo de las prácticas, algunos de los tipos de minerales más comunes que se pueden encontrar en el suelo. Estas fotografías, muchas a color, ponen en la mano del lector características como el color, la textura y, en términos generales, la apariencia que poseen las rocas, las cuales aparecen habitualmente contenidas en voluminosos atlas de mineralogía o textos especializados en geología, de difícil acceso por su elevado costo. Por el contrario, el tamaño de este libro lo hace cómodo e ilustrativo para llevarlo a campo y al laboratorio.

This book was released on 2020-08-13 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: El país está enfrentado un tema tan crítico como la apertura económica -tratados recién firmados como el TLC con Estados Unidos- obligan a los gremios del sector productivo a ser más competitivos si quieren continuar en el mercado. Uno de los elementos para mejorar este aspecto es la eficiencia en el uso de los recursos (fertilizantes, riegos, manejo sostenible del medio ambiente, etc.). La toma de decisiones es un paso difícil en cualquier empresa. En la empresa agropecuaria intervienen muchos elementos, componentes y variables que es necesario conocer a la hora de decidir. Como el momento de las decisiones y los resultados están alejados en el tiempo, los problemas se manifiestan cuando suele ser tarde para resolverlos. Así, para tomar buenas decisiones es fundamental una correcta información previa. Un análisis equivocado lleva siempre a un mal resultado; cuando los márgenes de ganancia de la actividad agropecuaria se reducen, el costo del error puede ser crítico. Las buenas decisiones solo pueden ser resultado de un correcto análisis de las variables y esto solo puede hacerse con buena información.

Download or read book Geotechnical Engineering in the XXI Century Lessons learned and future challenges written by N.P. López-Acosta and published by IOS Press. This book was released on 2019-11-26 with total page 3006 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Pan-American Conference on Soil Mechanics and Geotechnical Engineering (PCSMGE) was held in Mexico in 1959. Every 4 years since then, PCSMGE has brought together the geotechnical engineering community from all over the world to discuss the problems, solutions and future challenges facing this engineering sector. Sixty years after the first conference, the 2019 edition returns to Mexico. This book, Geotechnical Engineering in the XXI Century: Lessons learned and future challenges, presents the proceedings of the XVI Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XVI PCSMGE), held in Cancun, Mexico, from 17 – 20 November 2019. Of the 393 full papers submitted, 335 were accepted for publication after peer review. They are included here organized into 19 technical sessions, and cover a wide range of themes related to geotechnical engineering in the 21st century. Topics covered include: laboratory and in-situ testing; analytical and physical modeling in geotechnics; numerical modeling in geotechnics; unsaturated soils; soft soils; foundations and retaining structures; excavations and tunnels; offshore geotechnics; transportation in geotechnics; natural hazards; embankments and tailings dams; soils dynamics and earthquake engineering; ground improvement; sustainability and geo-environment; preservation of historic sites; forensics engineering; rock mechanics; education; and energy geotechnics. Providing a state-of-the-art overview of research into innovative and challenging applications in the field, the book will be of interest to all those working in soil mechanics and geotechnical engineering. In this proceedings, 58% of the contributions are in English, and 42% of the contributions are in Spanish or Portuguese.

Download or read book The Quijos Chiefdoms written by Andrea M. Cuéllar and published by Center for Comparative Arch. This book was released on 2009 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaeological study of the emergence of the ethnohistorically documented Quijos chiefdoms in the eastern Ecuadorian Andes. This research evaluates links between the emergence of centralized leadership and the organization of agricultural production. The focus is on reconstructing the demographic history of 137 km2 based on a full coverage systematic survey, and on reconstructing patterns of food production and consumption based on analysis of pollen, phytoliths and plant macroremains from the excavation of 31 tests at locations representing different environmental settings and settlement types. The study proposes a sequence starting at about 600 B.C., with the first manifestations of a regional system of centralized authority appearing after about 500 A.D. Neither control of basic resources nor specialized craft production seem to have been important in the social and political dynamics of the emerging Quijos chiefdoms.
