All pupils at Stoneyridge School have Review sessions. The students don't enjoy them, but understand they are used to improve their well-being and are simply a part of school life.

Zane Sampson is one of these students who has learnt to live with Reviews; however, after discovering that the school is secretly using these sessions to mark its students either as Eligible or Ineligible, Zane begins to question whether Stoneyridge is being entirely honest with its pupils.

Zane gradually comes to realise that he can only be sure of two things: all of his peers are being lied to, and until he unearths the actual purpose of their Reviews, he and his friends could be living in more danger than they know.

The book is about an unlikely friendship between Chilly, a bear cub and Quackers, a young duck and how they came to be acquainted. Through adventures together, they learned helpfulness and trust in spite of being from different species. The lesson gained from their story is universal regardless of your age or whether you are a bear or a duck!

This book provides an up-to-date survey of durability issues, with a particular focus on specification and design, and how to achieve durability in actual concrete construction. It is aimed at the practising engineer, but is also a valuable resource for graduate-level programs in universities. Along with background to current philosophies it gathers together in one useful reference a summary of current knowledge on concrete durability, includes information on modern concrete materials, and shows how these materials can be combined to produce durable concrete. The approach is consistent with the increasing focus on sustainability that is being addressed by the concrete industry, with the current emphasis on 'design for durability'.

Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.

In The Templar Treasure, Dr. Stuart Peterson is Curator of Medieval history at the prestigious British Museum. Stuart and his fiancé, Savanna, take a long overdue vacation to Troyes, France, planning on immersing themselves in the region's medieval history. Stuart's passion for Templar history and Savanna's love of medieval cathedrals draw them through the narrow streets of the quaint old town Tudor buildings.

However, Stuart is involved in an accident that could change their lives forever. This accident will propel him on a journey through Templar history, uncovering secrets from the past. Has this accident allowed Stuart to tap into a mystical collective consciousness? Could this information help lead him to where the Templar treasures are hidden today?

From the Order's founding to the insanity that occurred on Friday, October 13, 1307, Stuart uncovers what life was really like for a Templar knight in medieval times. However, one thing is for sure. This journey will make Stuart question his definition of reality.

This book provides an up-to-date survey of durability issues, with a particular focus on specification and design, and how to achieve durability in actual concrete construction. It is aimed at the practising engineer, but is also a valuable resource for graduate-level programs in universities. Along with background to current philosophies it gathers together in one useful reference a summary of current knowledge on concrete durability, includes information on modern concrete materials, and shows how these materials can be combined to produce durable concrete. The approach is consistent with the increasing focus on sustainability that is being addressed by the concrete industry, with the current emphasis on 'design for durability'.

Marine Concrete Structures: Design, Durability and Performance comprehensively examines structures located in, under, or in close proximity to the sea. A major emphasis of the book is on the long-term performance of marine concrete structures that not only represent major infrastructure investment and provision, but are also required to operate with minimal maintenance.

Chapters review the design, specification, construction, and operation of marine concrete structures, and examine their performance and durability in the marine environment. A number of case studies of significant marine concrete structures from around the world are included which help to reinforce the principles outlined in earlier chapters and provide useful background to these types of structures. The result is a thorough and up-to-date reference source that engineers, researchers, and postgraduate students in this field will find invaluable.

Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, whichmay be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe - adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss ofproduction during maintenance work, which place a great burden on society.

The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments, by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.
