Book Description
En un mundo donde la población crece de manera exponencial y los recursos naturales se ven sometidos a una presión sin precedentes, los fertilizantes desempeñan un papel crucial en la seguridad alimentaria, al maximizar la productividad de los cultivos. La formulación de fertilizantes nos permite dar soluciones específicas a problemáticas relacionadas con el rendimiento de los cultivos. Además, es importante conocer las fuentes de nutrientes, compatibilidad y factores que les afectan como: el pH, temperatura, balance iónico, entre otros, siendo estos primordiales para poder realizar un cálculo adecuado en el desarrollo de un fertilizante. Este manual contiene más de 100 propuestas de fórmulas de fertilizantes, que van desde aporte de NPK, hasta correctores de carencias múltiples adicionados con bioestimulantes como: hormonas, vitaminas, cofactores, extractos, adherentes, humectantes, conservadores, entre otros. Además, se listan las distintas fuentes de nutrientes que son utilizadas en la formulación de fertilizantes, así como ejemplos de desarrollos de nuevas formulaciones, herramientas para realizar el cálculo de soluciones nutritivas, la importancia del orden de adición entre los componentes de un fertilizante y los disolventes más comúnmente utilizados para activos con baja solubilidad en agua.

Book Description
This edition of the World Bank has been revised and expanded by the Terminology Unit in the Languages Services Division of the World Bank in collaboration with the English, Spanish, and French Translation Sections. The Glossary is intended to assist the Bank's translators and interpreters, other Bank staff using French and Spanish in their work, and free-lance translator's and interpreters employed by the Bank. For this reason, the Glossary contains not only financial and economic terminology and terms relating to the Bank's procedures and practices, but also terms that frequently occur in Bank documents, and others for which the Bank has a preferred equivalent. Although many of these terms, relating to such fields as agriculture, education, energy, housing, law, technology, and transportation, could be found in other sources, they have been assembled here for ease of reference. A list of acronyms occurring frequently in Bank texts (the terms to which they refer being found in the Glossary) and a list of international, regional, and national organizations will be found at the end of the Glossary.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
Dennis Dalton's classic account of Gandhi's political and intellectual development focuses on the leader's two signal triumphs: the civil disobedience movement (or salt satyagraha) of 1930 and the Calcutta fast of 1947. Dalton clearly demonstrates how Gandhi's lifelong career in national politics gave him the opportunity to develop and refine his ideals. He then concludes with a comparison of Gandhi's methods and the strategies of Martin Luther King Jr. and Malcolm X, drawing a fascinating juxtaposition that enriches the biography of all three figures and asserts Gandhi's relevance to the study of race and political leadership in America. Dalton situates Gandhi within the "clash of civilizations" debate, identifying the implications of his work on continuing nonviolent protests. He also extensively reviews Gandhian studies and adds a detailed chronology of events in Gandhi's life.

Book Description
In this expanded and revised edition of a fresh and original case-study textbook on environmental ethics, Christine Gudorf and James Huchingson continue to explore the line that separates the current state of the environment from what it should be in the future. Boundaries begins with a lucid overview of the field, highlighting the key developments and theories in the environmental movement. Specific cases offer a rich and diverse range of situations from around the globe, from saving the forests of Java and the use of pesticides in developing countries to restoring degraded ecosystems in Nebraska. With an emphasis on the concrete circumstances of particular localities, the studies continue to focus on the dilemmas and struggles of individuals and communities who face daunting decisions with serious consequences. This second edition features extensive updates and revisions, along with four new cases: one on water privatization, one on governmental efforts to mitigate global climate change, and two on the obstacles that teachers of environmental ethics encounter in the classroom. Boundaries also includes an appendix for teachers that describes how to use the cases in the classroom.

Book Description
Since its inception, anthropology's authority has been based on the assumption that it is a unified discipline emanating from the West. In an age of heightened globalization, anthropologists have failed to discuss consistently the current status of their practice and its mutations across the globe. World Anthropologies is the first book to provoke this conversation from various regions of the world in order to assess the diversity of relations between regional or national anthropologies and a contested, power-laden Western discourse. Can a planetary anthropology cope with both the 'provincial cosmopolitanism' of alternative anthropologies and the 'metropolitan provincialism' of hegemonic schools? How might the resulting 'world anthropologies' challenge the current panorama in which certain allegedly national anthropological traditions have more paradigmatic weight - and hence more power - than others? Critically examining the international dissemination of anthropology within and across national power fields, contributors address these questions and provide the outline for a veritable world anthropologies project.
