En el primer capítulo, se destaca cómo el encalado y la fertilización mejoran el rendimiento del maíz, enfatizando en dosis óptimas de nutrientes. El segundo capítulo aborda la fertilización orgánica del pasto Mombasa bajo sombra de naranja, resaltando la superioridad de la pollinaza en el incremento de rendimiento y calidad del forraje. Los capítulos siguientes se centran en la edad óptima de corte para maximizar la biomasa del pasto Cuba OM-22, el manejo del King Grass como alternativa forrajera para el sector ganadero, y el desarrollo del forraje verde hidropónico de sorgo y maíz a dos densidades de siembra, demostrando que técnicas específicas de manejo y cultivo pueden significativamente influir en la productividad y sostenibilidad de la alimentación rumiante. A través de estos estudios, el libro propone soluciones prácticas y sustentables para mejorar la nutrición de rumiantes en entornos tropicales.

American Contract Law for a Global Age
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

American Contract Law for a Global Age by Franklin G. Snyder and Mark Edwin Burge of Texas A&M University School of Law is a casebook designed primarily for the first-year Contracts course as it is taught in American law schools, but is configured so as to be usable either as a primary text or a supplement in any upper-level U.S. or foreign class that seeks to introduce American contract law to students. As an eLangdell text, it offers maximum flexibility for students to read either in hard copy or electronic format on most electronic devices.

Why “American” Contract Law? Nearly all American contract law texts focus on U.S. law. This volume simply makes that focus explicit. Modern American lawyers face an increasingly global world, and the book makes it clear that American law is not the only important commercial law regime in the world. But much of the value that the cosmopolitan and transnational American-trained lawyer brings to the table is an understanding of the contract law of the United States. To this end, the venerable English cases that exemplify common law doctrine are here presented not in their hoary 19th century settings. but in the 21st century forms that students can intuitively grasp.

American Government and Politics in the Information Age
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This text is a comprehensive introduction to the vital subject of American government and politics. Governments decide who gets what, when, how (See Harold D. Lasswell, Politics: Who Gets What, When, How, [New York: McGraw-Hill, 1936]); they make policies and pass laws that are binding on all a society’s members; they decide about taxation and spending, benefits and costs, even life and death.Governments possess power—the ability to gain compliance and to get people under their jurisdiction to obey them—and they may exercise their power by using the police and military to enforce their decisions. However, power need not involve the exercise of force or compulsion; people often obey because they think it is in their interest to do so, they have no reason to disobey, or they fear punishment. Above all, people obey their government because it has authority; its power is seen by people as rightfully held, as legitimate. People can grant their government legitimacy because they have been socialized to do so; because there are processes, such as elections, that enable them to choose and change their rulers; and because they believe that their governing institutions operate justly.Politics is the process by which leaders are selected and policy decisions are made and executed. It involves people and groups, both inside and outside of government, engaged in deliberation and debate, disagreement and conflict, cooperation and consensus, and power struggles.In covering American government and politics, this text introduces the intricacies of the Constitution, the complexities of federalism, the meanings of civil liberties, and the conflicts over civil rights;explains how people are socialized to politics, acquire and express opinions, and participate in political life; describes interest groups, political parties, and elections—the intermediaries that link people to government and politics; details the branches of government and how they operate; and shows how policies are made and affect people’s lives.

This book is designed to help us understand the many changes to U.S. journalism and imagine new futures for it – futures in which it can serve as an even more useful tool for promoting a well-functioning society.

It provides a conceptual foundation for understanding the development, logic, and practice of journalism in the United States; describes some of the key challenges, tensions, and opportunities it has faced, is facing, and will likely face; and offers guidance to help individuals develop the skills needed engage in impactful journalism.

Rating
0.0 stars

The American Yawp constructs a coherent and accessible narrative from all the best of recent historical scholarship. Without losing sight of politics and power, it incorporates transnational perspectives, integrates diverse voices, recovers narratives of resistance, and explores the complex process of cultural creation. It looks for America in crowded slave cabins, bustling markets, congested tenements, and marbled halls. It navigates between maternity wards, prisons, streets, bars, and boardrooms. Whitman’s America, like ours, cut across the narrow boundaries that strangle many narratives. Balancing academic rigor with popular readability, The American Yawp offers a multi-layered, democratic alternative to the American past.

Analytical Chemistry 2.1
Unrestricted Use
CC BY
Rating
0.0 stars

As currently taught in the United States, introductory courses in analytical chemistryemphasize quantitative (and sometimes qualitative) methods of analysis along with a heavydose of equilibrium chemistry. Analytical chemistry, however, is much more than a collection ofanalytical methods and an understanding of equilibrium chemistry; it is an approach to solvingchemical problems. Although equilibrium chemistry and analytical methods are important, theircoverage should not come at the expense of other equally important topics.

The introductory course in analytical chemistry is the ideal place in the undergraduate chemistry curriculum forexploring topics such as experimental design, sampling, calibration strategies, standardization,optimization, statistics, and the validation of experimental results. Analytical methods comeand go, but best practices for designing and validating analytical methods are universal. Becausechemistry is an experimental science it is essential that all chemistry students understand theimportance of making good measurements.

My goal in preparing this textbook is to find a more appropriate balance between theoryand practice, between “classical” and “modern” analytical methods, between analyzing samplesand collecting samples and preparing them for analysis, and between analytical methods anddata analysis. There is more material here than anyone can cover in one semester; it is myhope that the diversity of topics will meet the needs of different instructors, while, perhaps,suggesting some new topics to cover.
