Progress of Recycling in the Built Environment

This report is a useful tool for countries starting to recycle aggregates or construction and demolition waste. It contains the latest developments in this field, introduces a completely new approach to the procedure of proportioning concrete mixtures with recycled aggregate, references recent publications, opinions and discrepancies in relation to the durability of recycled concrete, such as freeze-thaw standards, studies of chloride penetration and diffusion, and sulfate attacks, the use of the fine fraction

Progress in Temperate Fruit Breeding

Progress in Temperate Fruit Breeding

This book contains the papers and posters presented at the Eucarpia Fruit Breeding Section Meeting held at Wadenswil/Einsiedeln, Switzerland from August 30 to September 3, 1993. It gives an overview of the latest trends in temperate fruit breeding in Europe and overseas. Three subjects were considered in special workshops: durability of scab resistance in apple, biotechnology and molecular markers. One important aim of modern fruit breeding is stable resistance against pests and diseases. Molecular markers might help to identify the genetic basis of important characteristics related to disease and pest resistance and components of yield and quality. Gene transfer has been successfully applied in several fruit species. However, public opinion in many countries does not favour this new technology and its products. Despite these new approaches, traditional breeding methods still predominate; many aspects of traditional breeding are considered in this book. Genetic resources and their exploitation are discussed in a special chapter. Aspects of breeding minor crops such as walnut, almond, hippophae, cornel are also considered. Progress in Temperate Fruit Breeding should interest fruit breeders, pomologists, lecturers, students and growers.

A Field Guide to Plants of Costa Rica

A Field Guide to Plants of Costa Rica

At the biological crossroads of the Americas, Costa Rica hosts one of the widest varieties of plants in the wold, with habitats ranging from tidal mangrove swamps, and lowland rainforests, to dry tropical evergreen and deciduous forests. Field Guide to Plants of Costa Rica is a must-have reference guide for beginner and expert naturalists alike. It provides a thorough survey of more than 850 plant species, each entry accompanied by color photos and a concise yet detailed narrative description. Plants are conveniently grouped by the different types of vegetation: palms, tall trees, shrubs, woody vines, herbaceous vines, herbs, grasses and ferns. Along with 1400 color photographs, the guide also includes an illustrated glossary of plant parts, five maps of Costa Rica, and laminated covers for durability in the field. With so much readily accessible information, this book is essential for exploring Costa Rica’s common and conspicuous flora from the plants growing along the roadside to the best natural parks.
