Author: Mineral Nitrogen In The Plant-Soil System
Author: R HaynesPublisher: Elsevier
ISBN: 0323148166
Category : Science
Languages : en
Pages : 497
Book Description
Mineral Nitrogen in the Plant-Soil System provides integrated accounts of the transformations and fate of mineral nitrogen in the plant-soil system. This book emphasizes the understanding of various processes and the factors that affect these processes. It also focuses on the role of biological nitrogen fixation in nitrogen cycling in natural and agricultural systems. The book is divided into seven major chapters and each chapter is further subdivided into various subtopics. The first chapter introduces and outlines the origin, distribution, and cycling of nitrogen in natural and agricultural terrestrial ecosystems. Chapter 2 focuses on the processes of decomposition and mineralization-immobilization turnover. The processes of nitrification are discussed in detail in Chapter 3. The following four chapters discuss topics of retention and movement of nitrogen in soils; gaseous losses of nitrogen; uptake and assimilation of mineral nitrogen by plants; and lastly, the use of nitrogen in agronomic practice. The book will be invaluable to graduate students and researchers in the field of agriculture. This will also cater other parties interested, such as agronomists, soil scientists, plant physiologists, horticulturists, and foresters.
Environmental Protection
Author: Pamela HillPublisher: Oxford University Press
ISBN: 019022309X
Category : Nature
Languages : en
Pages : 257
Book Description
Although climate change and pollution make near-daily appearances in the news, humans have not always recognized that the environment needs to be protected. Only after the publication of Rachel Carson's Silent Spring in 1962 did environmental protection became a political and social priority. In Environmental Protection: What Everyone Needs to Know®, environmental lawyer Pamela Hill offers clear, engaging answers to some of the most pressing questions facing us today. She discusses the science behind current environmental issues, defining key terms such as ecosystems, pollutants, and endocrine disruptors. Hill explains why our environment needs protection, using examples from history and current events, from the Irish potato famine to the BP oil spill in the Gulf of Mexico and the drinking water crisis in Flint, Michigan. She also assesses the effectiveness of landmark laws and treaties, including the Clean Air Act, the Endangered Species Act, and the Kyoto Protocol. To what extent is it acceptable to rank human interests over ecological interests? And is it fair to ask developing countries to reduce emissions, even though they bear little responsibility for our current environmental problems? Hill identifies the greatest environmental threats we are facing today and suggests what we need to do as citizens, businesspeople, and lawmakers to protect the environment for each other and for future generations.

The Calabi Problem for Fano Threefolds
Author: Carolina AraujoPublisher: Cambridge University Press
ISBN: 1009239651
Category : Mathematics
Languages : en
Pages : 452
Book Description
Algebraic varieties are shapes defined by polynomial equations. Smooth Fano threefolds are a fundamental subclass that can be thought of as higher-dimensional generalizations of ordinary spheres. They belong to 105 irreducible deformation families. This book determines whether the general element of each family admits a Kähler–Einstein metric (and for many families, for all elements), addressing a question going back to Calabi 70 years ago. The book's solution exploits the relation between these metrics and the algebraic notion of K-stability. Moreover, the book presents many different techniques to prove the existence of a Kähler–Einstein metric, containing many additional relevant results such as the classification of all Kähler–Einstein smooth Fano threefolds with infinite automorphism groups and computations of delta-invariants of all smooth del Pezzo surfaces. This book will be essential reading for researchers and graduate students working on algebraic geometry and complex geometry.
