Dynamics and Control of Energy Systems

This chapter focuses on strawberry root growth and architecture, discussing apical dominance, lateral root formation and allelopathic sensitivity. An architectural model of strawberry root growth is presented, showing that, if temperature and water availability are at optimal levels, the proliferation of roots in favourable soil patches is rapid, as is the depletion of nutrients and the accumulation of allelochemicals.

The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories. Helmut van Emden is Emeritus Professor of Horticulture at the University of Reading, UK. He has researched on aphids for over 50 years and has wide international experience, including in the tropics. Richard Harrington retired in 2015 as Head of the Rothamsted Insect Survey, with which he worked for 36 years on aphid monitoring and forecasting. He led the EU project “EXAMINE” (Exploitation of Aphid Monitoring In Europe) which brought together colleagues involved in aphid monitoring throughout Europe and beyond.

Taking on the key issues in urban design, Shaping the City examines the critical ideas that have driven these themes and debates through a study of particular cities at important periods in their development. As well as retaining crucial discussions about cities such as Los Angeles, Atlanta, Chicago, Detroit, Philadelphia, and Brasilia at particular moments in their history that exemplified the problems and themes at hand like the mega-city, the post-colonial city and New Urbanism, in this new edition the editors have introduced new case studies critical to any study of contemporary urbanism China, Dubai, Tijuana and the wider issues of informal cities in the Global South.

This is the first book on global agromining/phytomining technology. It presents the complete metal farming or agromining chain; an emerging technology expected to be transformative in the extraction of resources of those elements not accessible by traditional mining techniques. Meeting the demand for critical minerals (rare earth elements, platinum group elements, nickel cobalt) is increasingly difficult in the 21st century due to resource depletion and geopolitical factors.
