This book has following unique features that distinguish it from other works from the same area: 1) Investigates the influence of fissure geometry on strength failure and crack evolution behaviour of real rock material; 2) Analyzes the effect of pre-experiment high-temperature treatment on fracture mechanical behaviour of rock material with a single fissure or two parallel fissures; 3) Compares quantitatively simulated results using discrete element modelling and experimental results of fracture mechanical behaviour of rock material with two fissures; 4) Constructs the relationship between crack evolution processes and acoustic emission distribution of pre-fissured rock material under entire deformation; and 5) Discusses the crack evolution mechanism of pre-fissured rock material with respect to different confining pressures. This book can become the reference for technicians in the field of geotechnical engineering, mining engineering and geology engineering. At the same time, this book can be regarded as a good reference for scientific researchers carrying out fissured rock mechanics and correlated specialties.

Rock Dynamics – Experiments, Theories and Applications is a collection of scientific and technical papers presented at the Third International Conference on Rock Dynamics and Applications (RocDyn-3, Trondheim, Norway, 26-27 June 2018). The papers in the book reflect the recent developments in experiment and theory as well as engineering applications of rock dynamics. Rock dynamics studies the response of rock and rock masses under dynamic loading and during the state transition from static loading to kinetic movement. It also includes the study of engineering countermeasures to dynamic instability of rock and rock masses. The topics in the book include: - Dynamic theories - Numerical simulation - Propagation of stress waves - Dynamic tests of rock - Stability of underground openings under dynamic loading - Rockburst - Seismic monitoring - Dynamic rock support - Blasting - Earthquake-related rock structure damage, etc. Applications, such as rockburst, dynamic rock support, seismic monitoring, blasting and earthquake-related rock structure damage, are paid special attention in Rock Dynamics – Experiments, Theories and Applications. The papers, from specialists both from mining and tunnelling branches, discuss commonly interested dynamic issues. Their experience and knowledge in the application of rock dynamics are extremely valuable for all academics, engineers and professionals who work with rock dynamics.

Early-20th-century explorations of the Roman Forum at Ancient Corinth revealed a massive early imperial building now known as the Julian Basilica. The structure stood on a podium over four meters high, and it dominated the east end of the forum in size, aspect, and function until its destruction in the 4th century A.D. Within it was one of the largest known shrines to the imperial cult and the likely site of the imperial court of law for the Roman province of Achaia. The basilica housed 11 or more large-scale statues most likely to members of the Julio-Claudian family (including Augustus, Augustus's heirs Gaius and Lucius, and arguably Divus Iulius, Germanicus, Nero Caesar, and Claudius), as well as an altar to Divus Augustus and dedications to the genius Augusti, the gens Augusta, and other family members. This richly illustrated volume provides a contextual study of this important building, the remains of which were first published by Saul Weinberg in 1960 (Corinth I.5). Scotton treats the architectural remains, Vanderpool the sculptural remains, and Roncaglia the epigraphical material, each providing extensive catalogues with new photos, in addition to color reconstructions of the basilica and its grand interior.

Arnold, the third son of Dora and Paul von der Porten MD, was born in Hamburg, Germany in 1917. There came Hitlers rise to power. Arnolds father was an analytical thinker. On October 14, 1933 Paul sent Arnold, only 15, to Jamaica, British West Indies, with new clothes and M100, the maximum allowed to emigrants. Thus he escaped. Several relatives were murdered. Arnold describes his adventures, including those in World War II, in his book: The Nine Lives of Arnold. In 1953 Arnold and his wife, Amy, migrated to America, to his aging parents. Many who have read The Nine Lives of Arnold have begged Arnold to write his life after Kingston, Jamaica. This book tells. No-one shall be bored!
