Описание: The finite element method is the most powerful general-purpose technique for computing accurate solutions to partial differential equations. This book contains a thorough derivation of the finite element equations as well as sections on programming the necessary calculations, solving the finite element equations, and using a posteriori error estimates to produce validated solutions. Accessible introductions to advanced topics, such as multigrid solvers, the hierarchical basis conjugate gradient method, and adaptive mesh generation, are provided. Each chapter ends with exercises to help readers master these topics. The book is practical in nature. It includes a carefully documented collection of MATLAB programs implementing the ideas presented. Readers will benefit from a detailed explanation of data structures and specific coding strategies and will learn how to write a finite element code from scratch. Students can use the MATLAB codes to experiment with the method and extend them in various ways.

Описание: The monoculture systems that have been encouraged by governments since the 1960s have led to major socio-economic and environmental crises. Now the diversification of tree crop systems is advancing throughout the tropics. Why and when does diversification take place? What categories of farmers diversify? What obstacles do they have to overcome, and how do public and private policies interfere in this process? How do land use systems and landscapes evolve as a result of this diversification? According to the authors of this volume, diversification is certainly a response to market risks, but also to the depletion of environmental resources. Ecological changes such as declining soil fertility and increasing pressure from pests, diseases and weeds intensify at the end of monoculture cycles, driving crop change and diversification of farming systems. Through 15 case studies from Africa, Latin America, Asia and the Pacific, the authors provide us with in-depth insights into the economy and ecology of family agriculture and its recent developments.

Описание: The image of western ranchers making a stand for their “rights”—against developers, the government, “illegal” immigrants—may be commonplace today, but the political power of the cowboy was a long time in the making. In a book steeped in the culture, traditions, and history of western range ranching, Michelle K. Berry takes readers into the Cold War world of cattle ranchers in the American West to show how that power, with its implications for the lands and resources of the mountain states, was built, shaped, and shored up between 1945 and 1965.
After long days working the ranch, battling human and nonhuman threats, and wrestling with nature, ranchers got down to business of another sort, which Berry calls “cow talk.” Discussing the best new machinery; sharing stories of drought, blizzards, and bugs; talking money and management and strategy: these ranchers were building a community specific to their time, place, and work and creating a language that embodied their culture. Cow Talk explores how this language and its iconography evolved and how it came to provide both a context and a vehicle for political power. Using ranchers’ personal papers, publications, and cattle growers association records, the book provides an inside view of how range cattle ranchers in Arizona, New Mexico, Colorado, Wyoming, and Montana created a culture and a shared identity that would frame and inform their relationship with their environment and with society at large in an increasingly challenging, modernizing world.
A multifaceted analysis of postwar ranch life, labor, and culture, this innovative work offers unprecedented insight into the cohesive political and cultural power of western ranchers in our day.

The Confédération Paysanne, one of France's largest farmers' unions, has successfully fought against genetically modified organisms (GMOs), but unlike other allied movements, theirs has been led by producers rather than consumers. In Food, Farms, and Solidarity, Chaia Heller analyzes the group's complex strategies and campaigns, including a call for a Europe-wide ban on GM crops and hormone-treated beef, and a protest staged at a McDonald's. Her study of the Confédération Paysanne shows the challenges small farms face in a postindustrial agricultural world. Heller also reveals how the language the union uses to argue against GMOs encompasses more than the risks they pose; emphasizing solidarity has allowed farmers to focus on food as a cultural practice and align themselves with other workers. Heller's examination of the Confédération Paysanne's commitment to a vision of alter-globalization, the idea of substantive alternatives to neoliberal globalization, demonstrates how ecological and social justice can be restored in the world.

Описание: This book examines the development of innovative modern methodologies towards augmenting conventional plant breeding, in individual crops, for the production of new crop varieties under the increasingly limiting environmental and cultivation factors to achieve sustainable agricultural production, enhanced food security, in addition to providing raw materials for innovative industrial products and pharmaceuticals. This is Vol 6, subtitled Industrial and Food Crops, which consists of two parts. Included in Part I are 11 industrial plant species utilized as sources of raw materials for the production of industrial products including pulp and wood crops (acacia), fiber (cotton, jute and ramie), rubber (guayule and rubber tree), oil (jojoba and flax), biofuels and pharmaceutical (agave) and sugar source (sugarcane). Part II covers 7 food plants selected for their utilization in food industries for the production of chocolate (cacao), cooking oil (oil palm, safflower, sesame and sunflower) and natural flavors and aroma (saffron and vanilla). This volume is contributed by 60 internationally reputable scientists from 14 countries. Each chapter comprehensively reviews the modern literature on the subject and reflects the authors own experience.

Описание: Industrial Crops is the ninth book of the Handbook of Plant Breeding series. This volume focuses on the emerging areas of plant breeding for sustainable production of transportation fuels and biobased products using the current advances in the field. Individual chapters discuss crops being considered for different challenge areas such as oil crops for biodiesel; sugar, starch and cellulosic crops for biofuel; crops for bioproducts; and issues and future prospects. Specific issues covered encompass available germplasm, breeding techniques, and potential geographical areas of production for industrial uses. Outstanding scientists representing various national and international institutions contributed chapters within their expertise for each crop species. Diverse views and solutions are presented on the common issues that researchers on industrial crops are facing. This book serves as an up-to-date reference to researchers in both academic and industrial setting, to students and teachers of plant breeding, and to policy makers who are looking for alternative solutions to dependency on imported petroleum products.--
