Decision Support Systems for Weed Management


Book Description

Weed management Decision Support Systems (DSS) are increasingly important computer-based tools for modern agriculture. Nowadays, extensive agriculture has become highly dependent on external inputs and both economic costs, as well the negative environmental impact of agricultural activities, demands knowledge-based technology for the optimization and protection of non-renewable resources. In this context, weed management strategies should aim to maximize economic profit by preserving and enhancing agricultural systems. Although previous contributions focusing on weed biology and weed management provide valuable insight on many aspects of weed species ecology and practical guides for weed control, no attempts have been made to highlight the forthcoming importance of DSS in weed management. This book is a first attempt to integrate `concepts and practice’ providing a novel guide to the state-of-art of DSS and the future prospects which hopefully would be of interest to higher-level students, academics and professionals in related areas.




Neotropical Endophytic Fungi


Book Description

This pioneering book focuses on Neotropical endophytic fungi, providing a comprehensive overview of their diversity, ecology, and biotechnological applications in medicine, agriculture, and industry. Despite their rich diversity, the endophytic fungi associated with plants of Central and South American biomes remain largely unknown. The book addresses that knowledge gap by offering insights into Neotropic endophytic fungal community.




Nanotechnology and Plant Sciences


Book Description

This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants. The growing numbers of inventions in the field of nanotechnology are producing novel applications in the fields of biotechnology and agriculture. Nanoparticles have received much attention because of the unique physico-chemical properties of these compounds. In the life sciences, nanoparticles are used as “smart” delivery systems, prompting the Nobel Prize winner P. Ehrlich to refer to these compounds as “magic bullets.” Nanoparticles also play an important role in agriculture as compound fertilizers and nano-pesticides, acting as chemical delivery agents that target molecules to specific cellular organelles in plants. The influence of nanoparticles on plant growth and development, however, remains to be investigated. Lastly, this book reveals the research gaps that must be bridged in the years to come in order to achieve larger goals concerning the applications of nanotechnology in the plants sciences. In the 21st century, nanotechnology has become a rapidly emerging branch of science. In the world of physical sciences, nanotechnological tools have been exploited for a broad range of applications. In recent years, nanoparticles have also proven useful in several branches of the life sciences. In particular, nanotechnology has been employed in drug delivery and related applications in medicine.

Simone Weil


Book Description

Long before postmodern or deconstructionist ideas became current, Simone Weil was concerned with recognizing the absence of consistency and the continual presence of reversals and contradictions in life. She was someone for whom the task of clarifying her perceptions of reality and meaning was an ongoing one. She challenged contemporary views on such complex issues as human nature, good and evil, divinity and truth. Weil's work offers a voice for those segments of society that are generally under-represented, misrepresented or totally silent in conventional historical and philosophical writings. In this introduction to Simone Weil's ideas, and the political and intellectual circumstances of her work, the authors make Weil's complex and at times elusive ideas accessible to readers. They delineate how her ideas evolved, and provide compelling excerpts from her writings to let her speak for herself. In addition, the authors provide their own interpretation of Weil's work.
