Adventures in Volcanoland charts journeys across deserts, through jungles and up ice caps, to some of the world's most important volcanoes, from Nicaragua to Hawaii, Santorini to Ethiopia, exploring Tamsin Mather's obsession with these momentous geological formations, the cultural and religious roles they have played in the minds of those living around them at different times throughout history, and the science behind their formation and eruptions.
Volcanoes help to make and shape our world, bursting forth from inside of the earth and, in many places, looming over us. Present since the earth's beginning they continue to maintain its life support systems and, their extraordinary chemistry may even have created the ingredients needed for life to kick start.
In some places volcanoes are even beginning to provide us with part of the energy we need to curb our use of fossil fuels. They have fascinated humans for millennia, their eruptions charted throughout history, seeming to show us how the earth has been living, breathing and changing for billions of years.
Why exactly are these geological mammoths found where they are? What can they teach us about our environment, the Anthropocene and the ecological disaster that is climate change? Are there volcanoes on other planets, and what might they tell us about whether we could one day live there if we exhaust our own habitat? How can we predict if or when volcanoes might explode?
Adventures in Volcanoland is an enthralling mix of travel, science and environmental writing for fans of Robert MacFarlane and Raynor Winn.
The Welding of Aluminium and its Alloys is a practical user's guide
to all aspects of welding aluminium and aluminium alloys. It
provides a basic understanding of the metallurgical principles
involved showing how alloys achieve their strength and how the
process of welding can affect these properties. The book is
intended to provide engineers with perhaps little prior
understanding of metallurgy and only a brief acquaintance with the
welding processes involved with a concise and effective reference
to the subject.
It is intended as a practical guide for the Welding Engineer and
covers weldability of aluminium alloys; process descriptions,
advantages, limitations, proposed weld parameters, health and
safety issues; preparation for welding, quality assurance and
quality control issues along with problem solving.
The book includes sections on parent metal storage and preparation
prior to welding. It describes the more frequently encountered
processes and has recommendations on welding parameters that may be
used as a starting point for the development of a viable welding
procedure. Included in these chapters are hints and tips to avoid
some of the pitfalls of welding these sometimes-problematic
materials. The content is both descriptive and qualitative. The
author has avoided the use of mathematical expressions to describe
the effects of welding.
This book is essential reading for welding engineers, production
engineers, production managers, designers and shop-floor
supervisors involved in the aluminium fabrication industry.
A practical user's guide by a respected expert to all aspects of
welding of aluminiumDesigned to be easily understood by the
non-metallurgist whilst covering the most necessary metallurgical

Secret Service agent James Bond (Sean Connery) is sent to Jamaica to investigate the murder of one of his colleagues. It transpires that the island is being used as a base for the terrorist organisation SPECTRE, who, under the guidance of the despotic Dr No (Joseph Wiseman), have developed technology to divert rockets launched from Cape Canaveral. The first big-screen outing for 007 features original Bond Girl Ursula Andress emerging from the ocean in memorably revealing swimwear.
