This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduccion: El diseño es un proceso de ingeniería donde se genera toda una documentación tecnológica con el fin de producir un componente o máquina para su posterior desarrollo. El estudio realizado durante la ejecución de este trabajo ha dado como resultado un documento que presenta los principales criterios para el diseño de una Máquina Universal de Ensayos para materiales sintéticos. El diseño de este equipo presenta una posible solución para uno de los muchos problemas que se observan en las empresas, principalmente en el área de control de calidad de los productos. Uno de los puntos más críticos radica en la carencia de laboratorios de ensayos, lo cual impide realizar un seguimiento a las piezas para obtener una información estable y verídica en cuanto a la caracterización de las mismas que arroje datos para analizar las propiedades mecánicas de los elementos producidos en cada proceso de fabricación. Este trabajo se ha centrado en el ensayo aplicado para determinar la resistencia mecánica de los elementos listos para salir al mercado con el fin de garantizar las especificaciones para las cuales fueron diseñados, mediante la propuesta tecnológica de diseño del equipo empleado en dichos ensayos de caracterización. En nuestro medio, las industrias que fabrican piezas de materiales sintéticos se basan en datos empíricos para comprobar las características mecánicas de los materiales ya que no cuentan con cálculos ni datos específicos para el diseño y la producción de las piezas, por lo cual se recomienda la realización de pruebas de caracterización a los productos, principalmente una prueba de resistencia mecánica debido a que en su uso muchos de los elementos a base de materiales sintéticos son sometidos a esfuerzos de tracción o compresión.
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.
Download or read book Transport in Plants I written by M.H. Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

Download or read book Born Twice written by Giuseppe Pontiggia and published by Vintage. This book was released on 2007-12-18 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a breach birth leaves Paulo severely disabled, his father, the articulate, unsentimental Professor Frigerio, struggles to come to terms with his son’s condition. Face to face with his own limitations, Frigerio confronts the strange way society around him handles Paolo’s handicaps and observes his surprising gifts. In spare, deeply affecting episodes, the professor of language explores the nuanced boundaries between “normal” and “disabled” worlds. A remarkable memoir of fathering, winner of the 2001 Strega Prize, Italy’s most prestigious literary honor, Born Twice is noted Italian author Guiseppe Pontiggia’s American debut. Sometimes meditative, often humorous, and always probing, Pontiggia’s haunting characters linger and resound long after the book is done.

Available in PDF, EPUB and Kindle. Book excerpt: In the wake of tensions between modern and postmodern sensibilities, what larger directions now emerge in cultural anthropology? In this major work, Bruce Knauft takes stock of important recent initiatives in cultural and critical theory. By combining critical reviews and ethnographic engagements with fresh readings of major figures and approaches, the work develops a larger vantage point for considering the dispersing influence of practice theories, postmodernism, cultural studies, postcolonial studies, modern/post-positive feminism, and multicultural criticisms.

This book was released on 2020-07-28 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: MATEMAX is a bilingual schoolbook of mathematical problems written with the premise that one of the fundamental ways of learning mathematics, in addition to being one of the goals of the subject, is to solve problems. The book is designed for children and young teens and aims to teach mathematics in an entertaining way. Problems are based on familiar everyday situations, and helpful hints guide students to develop strategies before diving into calculations, leading to practice in abstract thinking, an essential feature of mathematics. Presented in both English and Spanish it also provides equal access to students, parents and teachers with facility in either or both languages. An online supplement is available upon request at [email protected]. This companion book provides complete solutions, alternative methods and additional suggestions to complement the short answers contained in the book. In addition, while problems are arranged in the book as they appear naturally in life, the companion text connects the mathematical tools with standard curricula. Here is a sampling of those pages.

Download or read book Analysis of Turbulent Boundary Layers written by Tuncer Cebeci and published by Elsevier. This book was released on 2012-12-02 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of Turbulent Boundary Layers focuses on turbulent flows meeting the requirements for the boundary-layer or thin-shear-layer approximations. Its approach is devising relatively fundamental, and often subtle, empirical engineering correlations, which are then introduced into various forms of describing equations for final solution. After introducing the topic on turbulence, the book examines the conservation equations for compressible turbulent flows, boundary-layer equations, and general behavior of turbulent boundary layers. The latter chapters describe the CS method for calculating two-dimensional and axisymmetric laminar and turbulent boundary layers. This book will be useful to readers who have advanced knowledge in fluid mechanics, especially to engineers who study the important problems of design.
