Sommario/riassunto |

Two discoveries of early human relatives, one in 1924 and one in 2003, radically changed scientific thinking about our origins. Dean Falk, a pioneer in the field of human brain evolution, offers this fast-paced insider's account of these discoveries, the behind-the-scenes politics embroiling the scientists who found and analyzed them, and the academic and religious controversies they generated. The first is the Taung child, a two-million-year-old skull from South Africa that led anatomist Raymond Dart to argue that this creature had walked upright and that Africa held the key to the fossil ancestry of our species.

second find consisted of the partial skeleton of a three-and-a-half-foot-tall woman, nicknamed Hobbit, from Flores Island, Indonesia. She is thought by scientists to belong to a new, recently extinct species of human, but her story is still unfolding. Falk, who has studied the brain casts of both Taung and Hobbit, reveals new evidence crucial to interpreting both discoveries and proposes surprising connections between this pair of extraordinary specimens. |

Introduction and Scope-During the last few decades, an enormous effort has been made to understand corrosion phenomena and their mechanisms, and to elucidate the causes that dramatically influence the service lifetime of metal materials. The performance of metal materials in aggressive environments is critical for a sustainable society. The failure of the material in service impacts the economy, the environment, health, and society. In this regard, corrosion-based economic losses due to maintenance, repair, and the replacement of existing structures and infrastructure account for up to 4% of gross domestic product (GDP) in well developed countries. One of the biggest issues in corrosion engineering is estimating service lifetime. Corrosion prediction has become very difficult, as there is no direct correlation with service lifetime and experimental lab results, usually as a result of discrepancies between accelerated testing and real corrosion |

processes. It is of major interest to forecast the impact of corrosion-based losses on society and the global economy, since existing structures and infrastructure are becoming old, and crucial decisions now need to be made to replace them. On the other hand, environmental protocols seek to reduce greenhouse effects. Therefore, low emission policies, in force, establish regulations for the next generation of materials and technologies. Advanced technologies and emergent materials will enable us to get through the next century. Great advances are currently in progress for the development of corrosion-resistant metal materials for different sectors, such as energy, transport, construction, and health. This Special Issue on the corrosion and protection of metals is focused on current trends in corrosion science, engineering, and technology, ranging from fundamental to applied research, thus covering subjects related to corrosion mechanisms and modelling, protection and inhibition processes, and mitigation strategies. |
