Natural Disasters and Extreme Events in Agriculture : Impacts and Mitigation
Agricultural production is highly dependent on weather, climate and water availability and is adversely affected by the weather and climate-related disasters. Droughts and natural disasters such as floods can result in crop failures, food insecurity, famine, loss of property and life, mass migration and negative national economic growth. It may not be possible to prevent the occurrence of these natural disasters, but the resultant disastrous effects can be reduced considerably through proper planning and effective preparation. Vulnerability associated with the hazards of natural disasters can be controlled to some extent by accurate and timely prediction and by taking counter-measures to reduce their impacts on agriculture. This book based on an expert meeting held in Beijing, China should be of interest to all organizations involved in disasters reduction and mitigation of extreme events.
Monitoring State Compliance with the UN Convention on the Rights of the Child : An Analysis of Attributes
This book presents a discussion on human rights-based attributes for each article pertinent to the substantive rights of children, as defined in the United Nations Convention on the Rights of the Child (UNCRC). It provides the reader with a unique and clear overview of the scope and core content of the articles, together with an analysis of the latest jurisprudence of the UN Committee on the Rights of the Child. For each article of the UNCRC, the authors explore the nature and scope of corresponding State obligations, and identify the main features that need to be taken into consideration when assessing a State’s progressive implementation of the UNCRC. This analysis considers which aspects of a given right are most important to track, in order to monitor States' implementation of any given right, and whether there is any resultant change in the lives of children.
Introduction à la résolution des systèmes polynomiaux = Introduction to solving polynomial systems
This book is an introduction to algebraic methods for solving this type of equations. We show how the geometry of algebraic varieties defined by these equations, their dimension, their degree, or their components can be deduced from the properties of the corresponding quotient algebras. For this, we approach methods of effective algebraic geometry, such as Grobner bases, resolution by eigenvalues and vectors, resultants, bezoutians, duality, Gorenstein algebras and algebraic residues.
Elasto-Plastic and Damage Analysis of Plates and Shells
This book presents a finite element model for the elasto-plastic and damage analysis of thin and thick shells. Linear elastic, inelastic and softening behaviors caused by damage in structural shells, as well as large rotations are investigated.
Courbes algébriques planes = Plane Algebraic Curves
Resulting from a master's course at the University of Paris VII, this text is re-edited as it appeared in 1978. Various tools are introduced in connection with Bézout's theorem necessary for the development of the notion of the multiplicity of intersection of two algebraic curves in the complex projective plane. Starting from elementary notions on affine and projective algebraic subsets, we define the intersection multiplicities and interpret their sum in terms of the resultant of two polynomials. The local study is a pretext for the introduction of formal or convergent series rings; it culminates in Puiseux's theorem, the convergence of which is reduced by splits to that of the theorem of implicit functions. Various figures illuminate the text: we "see" in particular that the homogeneous equation x3 + y3 + z3 = 0 defines a torus in the complex projective plane.
Approaches to Fundamental Physics : An Assessment of Current Theoretical Ideas
This book presents contributions on particle theory, quantum field theory, general relativity, quantum gravity, string theory and cosmology. These represent the outcome of numerous discussions, taking place among the authors over a period of several years, about the research landscape of present-day fundamental theoretical physics. Indeed, the resultant book documents their attempt, out of their respective and highly specialized scientific positions, to find a way of communicating about methods, achievements and promises of the different approaches which shape the development of this field. It is therefore also an attempt to elucidate the connections between these approaches, and present them not as disjoint ventures but rather as facets of a common quest for understanding. Readers interested in fundamental approaches of theoretical physics will find this book highly stimulating and enlightening.
