Permaculture for Beginners – Knowledge and Basics of PermacultureWouldn't it be wonderful if our buildings and automobiles could filter water and at the same time improve air quality?If we could replenish the environment, our world could be a wonderfully clean place.But how exactly how does permaculture change the world?On the one hand, we can change permaculture deserts into productive oases to produce food...

Considers the role of fertiliser use in agriculture as a major contributor to the imbalance of the global nitrogen cycleReviews the effectiveness of inorganic nitrogen fertilisers and organic sources of nitrogen in optimising nitrogen use efficiencyHighlights recent developments in the use of enhanced efficiency nitrogen fertilisers to reduce nitrous oxide emissions

While grasslands face a number of challenges, such as land-use competition and the impact of climate change, there is a growing recognition of the critical role they play in supporting the transition to more resilient, sustainable and circular agricultural systems.Advances in temperate grassland science and management reviews the wealth of research addressing these challenges and opportunities. The book highlights the potential of grasslands to deliver multiple benefits to...

With the agricultural sector pledging to improve its sustainability, there is an urgent need to move away from linear food production models which rely on significant raw material inputs and generate large amounts of residual waste.Developing circular agricultural production systems reviews the emergence of circular agriculture as an approach to improving the sustainability of the agricultural sector. The book addresses recent advances in understanding and...

The definitive book on owls.Owls are enduringly popular birds, but due to their nocturnal habits most species are difficult to see well. The plumages of many species are cryptic and difficult to separate by plumage alone. This problem is compounded by the different morphs that many adopt.This book fully describes every known species and subspecies of owl, as well as presenting the latest evidence on owl taxonomy, based on DNA work and vocalisations. Because...

This book features four peer-reviewed reviews on regenerative techniques to improve soil health.The first chapter discusses some common issues regarding the use of bio-based fertilisers, such as the concentration of nutrients leading to losses of reactive nitrogen (N) and phosphorus into the environment.The second chapter provides a critical evaluation of the potential of compost to improve soil health, as well as its effect on soil nutrient cycling, soil hydraulic properti...

The Polish crisis in the early 1980s provoked a great deal of reaction in the West. Not only governments, but social movements were also touched by the establishment of the Independent Trade Union Solidarnosc in the summer of 1980, the proclamation of martial law in December 1981, and Solidarnosc's underground activity in the subsequent years. In many countries, campaigns were set up in order to spread information, raise funds, and provide the Polish opposition with humanitarian relief and...

The many-body-theoretical basis and applications of theoretical spectroscopy of condensed matter, e.g. crystals, nanosystems, and molecules are unified in one advanced text for readers from graduate students to active researchers in the field. The theory is developed from first principles including fully the electron-electron interaction and spin interactions. It is based on the many-body perturbation theory, a quantum-field-theoretical description, and Green's functions. The important exp...

Recognizing both the potential of biblical prohibition of images for causing religious conflict and the promise of a more nuanced appreciation of the role of images in human experience, this book constructs a framework for understanding the place of images, and their prohibition, within the biblical text and Christian religious practice.

Focuses on plant health issues in sub-Saharan Africa which are key to improving yieldsReviews ways of improving the health of key African crops such as cassava, maize and grain legumesBrings together leading experts on plant health in sub-Saharan Africa

Originally published in 1977, this volume traces the development of literary forms and themes and of movements and schools, during the overtly philosophical age. It begins with the prominent poets of the 1720s and 1730s: Brockes, Hagedorn and Haller. It charts the many attempts at formulating poetic theory, particularly those of Gottsched, Bodmer and Breitnger. Emphasis is placed on the dramatic writings of J. E. Schlegel, Gellert and Ch. F. Weisse. Young Goethe’s creativity in all genres,...

This book constitutes the thoroughly refereed revised selected papers from the Second IAPR International Workshop, PSL 2013, held in Nanjing, China, in May 2013. The 10 papers included in this volume were carefully reviewed and selected from 26 submissions. Partially supervised learning is a rapidly evolving area of machine learning. It generalizes many kinds of learning paradigms including supervised and unsupervised learning, semi-supervised learning for classification and regression, tr...
