Growing Plantation Forests
Plantation forests are grown to supply wood and to provide environmental benefits, such as waste disposal, rehabilitation of degraded sites, enhancement of regional biodiversity and reduction of logging in native forests. In a highly readable fashion, this book describes the scientific principles which are used throughout the world to ensure rapid, healthy plantation growth. It is written for a world-wide audience, from forestry professionals and scientists through to small plantation growers, to describe how plantations may be grown responsibly and profitably.
Growing Food : A guide to food production
This specialist handbook is intended as a quick and easy reference guide for individuals and organisations that are involved with the production of food, from both agriculture and horticulture. It is designed to be used as a reference book that answers basic questions about how food is produced from plants, and aims to demystify the subject of growing food as far as possible. The focus is firmly on the technical aspects of food crops; animal husbandry, agrochemicals and genetic engineering are only briefly mentioned. The book is divided into three sections: 1. Principles and Practices used in Agriculture and Horticulture; 2. Description and Characteristics of the Main Food Crops; 3. Naming and Classification of Plants, Seed Purchase Procedures, Conversion Tables and Statistics, Planning and Assessing Agricultural Projects.

Grouping Multidimensional Data : Recent Advances in Clustering
Clustering is one of the most fundamental and essential data analysis techniques. Clustering can be used as an independent data mining task to discern intrinsic characteristics of data, or as a preprocessing step with the clustering results then used for classification, correlation analysis, or anomaly detection.
Group-based Cryptography
This book is about relations between three different areas of mathematics and theoretical computer science: combinatorial group theory, cryptography, and complexity theory. It is explored how non-commutative (infinite) groups, which are typically studied in combinatorial group theory, can be used in public key cryptography. It is also shown that there is a remarkable feedback from cryptography to combinatorial group theory because some of the problems motivated by cryptography appear to be new to group theory, and they open many interesting research avenues within group theory.
Group rights as human rights : A liberal approach to multiculturalism
Liberal theories have long insisted that cultural diversity in democratic societies can be accommodated through classical liberal tools, in particular through individual rights, and they have often rejected the claims of cultural minorities for group rights as illiberal. Group Rights as Human Rights argues that such a rejection is misguided. Based on a thorough analysis of the concept of group rights, it proposes to overcome the dominant dichotomy between "individual" human rights and "collective" group rights by recognizing that group rights also serve individual interests.
Group interventions in schools : Promoting mental health for at-risk children and youth
Children who are labeled at-risk often suffer from severe deficiencies in cognitive, affective, and behavioral skills that, if unaddressed, may lead to limited prospects for future success and well-being. Tapping into the therapeutic potential of groups, this volume presents the theory and practice of cognitive-oriented group-centered counseling – combining intrinsic motivation, efficacy retraining, and targeted play therapy and social role-playing – that can be implemented to help children build core social skills and emotional regulation to complement their classroom instruction.
Group B Coxsackieviruses
This monograph reviews information published since 1997 on the group B coxsackieviruses (CVB), a large and important group of human enteroviruses. The CVB were discovered in the mid-20th century, during the search for other poliovirus types, and within a very few years of this discovery, the CVB had been implicated as causes of human myocarditis and pancreatitis. The study of the CVB is still inextricably linked with the fate of their well-known relatives, the polioviruses, for as poliovirus eradication proceeds around the world, the CVB emerge more prominently as the enteroviruses best suited for continuing studies in enteroviral molecular biology as well as understanding the mechanisms underlying enteroviral pathogenesis. This volume reviews and presents modern views on the spectrum of CVB biologies, from interaction of the virus with its receptor through replication, speciation, and induction of disease.
Group 13 Chemistry III : Industrial Applications
The present issue of Structure and Bonding is dedicated to applied group 13 chemistry, particularly for the elements boron and aluminum, and to a lesser degree gallium and indium. Although boron is a trace element (0.01 g kg 1) in the earth's crust, it has been concentrated in a few locations by geochemical processes and is relatively easy to mine as borax. Aluminum, on the other hand, is the most abundant metal in the earth's crust (82 g kg 1) and dispersed widely throughout the globe. In the chapter Schubert explains the close relationship between the basic properties of the boron compounds and their associated uses. The remaining four chapters focus, to some degree, on aluminum. Since a great deal of literature exists in this area, these chapters are more focused on areas of emerging utility, and contain a great deal of fundamental information. Uhl's contribution in Chapter 2 provides basic synthesis and structural information for aluminum and gallium hydrazides. These types of compounds are being explored as potential molecular precursors to metal nitrides such as the important blue green laser material gallium nitride.
Group 13 Chemistry I : Fundamental New Developments
Depending on the use of the elements, the resulting work can be described under any heading of chemistry. The group 13 elements have been special in this regard due to the very unique characters of the constituent elements. Thus, there is a dramatic change in the properties of the elements when proceeding through the series, B, A1, Ga, In, T1. This difference is one of the main reasons why these elements have seen, and continue to see, such widespread usage in such disparate applications as organic synthesis, electronic and structural materials, and catalysis, to name but a few.
Groundwater Recharge from Run-off, Infiltration and Percolation
This book first discusses the recharge fluxes relating both to the quantity and quality of groundwater. In order to face the threats to the water supply and to be able to maintain a sustainable water management policy, detailed knowledge is needed in between others on the surface to subsurface transformation link in the water cycle. Secondly, the presentation and comparison of both the traditional and modern approach to determine groundwater recharge is discussed. The traditional approach to determine groundwater recharge, is based on water balance estimates and hydraulic considerations, which yield instantaneous values at best but do not integrate the totality of recharge pathways in time and space. In contrast, environmental tracers do integrate these factors. Finally, the fate of groundwater recharge in the subsurface by hydraulic and geologic means is discussed in detail, in order to stimulate adapted groundwater management strategies and to better assess consequences of climate changes on groundwater resources as a whole.
Groundwater overexploitation in the North China Plain : A path to sustainability
Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief.
Groundwater Management in Asian Cities : Technology and Policy for Sustainability
The number of city dwellers who do not have access to piped water and rely on groundwater is also increasing. In many Asian cities, groundwater is not only the source of domestic water but also an important resource for industrial development, making better management of groundwater resources essential for sustainable development. Because groundwater is easier to access and costs less than water from piped systems, groundwater abstraction cannot be easily regulated. Policies for groundwater management adopted in Japan and other Asian countries are compared, and technologies for efficient use of groundwater are elucidated. Groundwater contamination is also a serious problem that exacerbates water scarcity in Asian cities. Case studies illustrate the cause and consequences of naturally occurring contaminants such as arsenic and fluoride, and groundwater contamination due to anthropogenic contaminants is described. Also discussed are technologies for treating contaminated groundwater to reduce the health risks of drinking contaminated groundwater.
Groundwater Geophysics : A Tool for Hydrogeology
Geophysical techniques can map the underground conditions apart from boreholes. The use of these methods for hydrogeological applications is demonstrated for mapping of porous and structural aquifers, determination of groundwater quality (mineralization), assessment of hydraulic properties, determination of aquifer vulnerability and mapping of contaminated sites. Additionally, a description of geophysical techniques used for groundwater studies is given including seismics, resistivity methods, magnetics, ground penetrating radar and NMR (nuclear magnetic resonance).
Groundwater Geochemistry : A Practical Guide to Modeling of Natural and Contaminated Aquatic Systems
Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration.
Groundwater Geochemistry : A Practical Guide to Modeling of Natural and Contaminated Aquatic Systems

Groundwater Dynamics in Hard Rock Aquifers : Sustainable Management and Optimal Monitoring Network Design
Groundwater is of utmost importance in the arid and semi-arid environment. The areas in such regions are forced to face a variety of problems regarding groundwater as it is the main source of water no matter for any use viz., drinking, domestic, irrigation or industrial particularly for the rural population. The main challenges in hard rock areas in the semi-arid region are the water conservation, management and planning of the water resources. This is further complicated with several complexities of the geological formation. With the semi-arid environment, complex geological settings and over shooting stresses, the aquifer system becomes extremely fragile and sensitive. In spite of a good amount of research in this field, it is still needed to understand the behaviour of such complex system precisely and also apply the result in reasonably larger scales.
