Thermodynamic data, in conjunction with appropriate software for calculation of complex chemical equilibria, are finding wide application in many areas of materials design and development. In particular, there have been enormous advances in the thermodynamic modelling of alloy solution phases, whereby a knowledge of the underlying crystallographic structure of each phase is fundamental to a reliable representation of the thermodynamic properties and phase equilibria of a particular system of interest. With the aid of thermodynamic calculations, considerable time and costs can and are being saved in producing a material of the required composition and phase constitution required for a particular application. SGTE has been at the forefront in providing critically assessed thermodynamic data for alloy systems and has provided guidelines for the modelling of alloy phases of different types.
Exploring the dramatic growth and changes in the field of vermicomposting since 1988, this comprehensive review assesses the advancements made in government-funded projects in the U.S. and UK. It discusses outdoor and indoor windrows, container systems, wedge systems, and low labor-requirements. It also examines fully-automated continuous flow vermicomposting reactor systems that can process more than 1000 tons of organic wastes per reactor. The book highlights the science and biology behind the use and efficacy of vermicomposting and details the technology of the past, present, and future.
'I thought I knew quite a bit about earthworms – until I picked up this charming little book' Nick Baker 'Many wonderful wormy tales unearthed by Coulthard' BBC Countryfile Magazine 'A gem of a book' Country Smallholding Without these little engineers of the earth, the world's soils would be barren, and our gardens and fields wouldn't be able to grow the food we need to survive. Worms recycle decaying plants, putting nutrients back into the soil; they provide a food source for wildlife; and their constant burrowing helps heavy rain soak away. Sally Coulthard's fascianting guide offers a wealth of information and practical advice about the world's msot industrious but little understood creature.
