In the 1960s, a group of Italian scholars undertook underground dowsing and geological research, particularly in the area between the Pre-Alps and the Po Valley (Italy), with the aid of an electronic instrument developed by Eng. Alessandro Porro. The working group led by Eng. Porro also included a geologist, Prof. Floriano Villa, and a journalist of the "Corriere della Sera", Mario Miniaci. The results of the research, noted in the form of a 'Diary' by Mario Miniaci, were astonishing: there were vestiges of an intelligent and technologically advanced species which had lived on Earth during the Eocene epoch, millions of years before the appearance of the human race. The Diary, together with m...
Amazonia has long been a focus of debate about the impact of the tropical rain forest environment on indigenous cultural development. This edited volume draws on the subdisciplines of anthropology to present an integrated perspective of Amazonian studies. The contributors address transformations of native societies as a result of their interaction with Western civilization from initial contact to the present day, demonstrating that the pre- and postcontact characteristics of these societies display differences that until now have been little recognized. CONTENTS Amazonian Anthropology: Strategy for a New Synthesis, Anna C. Roosevelt The Ancient Amerindian Polities of the Amazon, Orinoco and ...
Ambitious, extravagant, progressive, and sexually notorious, Galeazzo Maria Sforza inherited the ducal throne of Milan in 1466, at the age of twenty-two. Although his reign ended tragically only ten years later, the young prince's court was a dynamic community where arts, policy making, and the panoply of state were integrated with the rhythms and preoccupations of daily life. Gregory Lubkin explores this vital but overlooked center of power, allowing the members of the Milanese court to speak for themselves and showing how dramatically Milan and its ruler exemplified the political, cultural, religious, and economic aspirations of Renaissance Italy. Ambitious, extravagant, progressive, and sexually notorious, Galeazzo Maria Sforza inherited the ducal throne of Milan in 1466, at the age of twenty-two. Although his reign ended tragically only ten years later, the young prince's court was a dynamic comm
This book captures the state of the art of the durability of fibre-reinforced strain-hardening cement-based composites (SHCC) and the durability of structures or structural elements manufactured in full or in part with this class of modern construction materials. Highlights include: - Reflection on durability performance of existing applications in patch repair, a water reservoir and highway bridges. - Guidelines for tensile testing towards durability assessment of cracked SHCC. - New crack pattern related ingress rate indices for water and chloride into cracked SHCC. - The influence of low and high temperatures on SHCC durability performance. - The mechanism of crack control reducing ASR and corrosion rate, and results on chloride-induced corrosion of embedded steel reinforcement. - Self-healing of cracks in SHCC. - A conceptual durability design framework for SHCC and R/SHCC structures and members.

This book gathers peer-reviewed contributions presented at the 3rd International Conference on Innovative Technologies for Clean and Sustainable Development, held in Chandigarh, India, on February 19-21, 2020. The respective papers focus on sustainable materials science and cover topics including the durability and sustainability of concrete, green materials in construction, economics of cleaner production, environmental impact mitigation, innovative materials for sustainable construction, performance and sustainability of special concrete, renewable energy infrastructure, sustainability in road construction, sustainable concrete, sustainable construction materials, waste minimization & management, prevention and management of water pollution, and zero-energy buildings.
This volume highlights the latest advances, innovations, and applications in the field of sustainable concrete structures, as presented by scientists and engineers at the RILEM International Conference on Numerical Modeling Strategies for Sustainable Concrete Structures (SSCS), held in Marseille, France, on July 4-6, 2022. It demonstrates that numerical methods (finite elements, finite volumes, finite differences) are a relevant response to the challenge to optimize the utilization of cement in concrete constructions while checking that these constructions have a lifespan compatible with the stakes of sustainable development. They are indeed accurate tools for an optimized design of concrete...
Self-healing materials are man-made materials which have the built-in capability to repair damage. Failure in materials is often caused by the occurrence of small microcracks throughout the material. In self-healing materials phenomena are triggered to counteract these microcracks. These processes are ideally triggered by the occurrence of damage itself. Thus far, the self-healing capacity of cement-based materials has been considered as something "extra". This could be called passive self-healing, since it was not a designed feature of the material, but an inherent property of it. Centuries-old buildings have been said to have survived these centuries because of the inherent self-healing capacity of the binders used for cementing building blocks together. In this State-of-the-Art Report a closer look is taken at self-healing phenomena in cement-based materials. It is shown what options are available to design for this effect rather than have it occur as a "coincidental extra".
