Abstract

Metals such as copper, iron, manganese, and zinc are clearly required for proper metabolism and development, while imbalances can lead to systemic dysfunction and disease. As a result, organisms have evolved complex genetic systems for the regulation of metal levels, including import, export, and sequestration of metals within cells and sub-cellular compartments.

The study of metal biology in insects has the potential to greatly expand our understanding of metal biology. The results of such studies might point to new possible therapeutic interventions for neurological and other human diseases, as well as new strategies for insect disease vector control.

The articles collected in this Research Topic comprise review and original research on metal biology in insects.

Abstract

From simple inorganic catalysts to vital biological cofactors, divalent transition metals are instrumental to electron transfers, catalysis and signaling. Their natural ability to bind, exchange and react with organic molecules including oxygen requires from living cells to regulate uptake with metabolic activities, sensing and chaperoning, distributing and storing, or excreting excess to prevent detrimental biochemical reactions. Since transition metal deficiency and overload both limit cell growth it is no surprise that the immune system evolved a dual strategy, of metal starvation or intoxication, to thwart microbial invasions. Like environmental metal availability determined biological use it also shaped host-microbe metal economy: Fe and Mn, available early in evolution and still required rather ubiquitously, are generally withheld by host in response to infection; Zn and Cu, which became bioavailable later, essentially to eukaryotic cells may be bombarded toward invaders. Successful microbial pathogens have evolved elaborate counter-measures to cope with host metal defenses. This research topic aims to review and discuss metal currencies in host-microbe interactions focusing on new findings about micro-organism pathogenesis determinants in the face of host innate strategies to interfere with microbial physiology.

Abstract

Juché dès le tournant des XI-XIIe s. sur un éperon rocheux aux pentes vertigineuses, dominant le cours d’un torrent montagnard, le château d’Essertines a constitué pendant tout le Moyen Âge une défense rapprochée de Montbrison, capitale des comtes de Forez. Sa situation, ses enceintes et bon nombre des objets mis au jour par la fouille soulignent sa vocation militaire. L’exploration archéologique a redécouvert les bâtiments qui se sont succédé au cœur de la forteresse, les traces des incendie...

Abstract

Slide 1Les Scories de forge du Pays dogonLes Scories de forge du Pays dogon (Mali)Entre ethnoarchéologie, archéologie expérimentale et archéométrieCet ouvrage est le résultat d’une thèse de doctorat menée entre le Pays dogon au Mali, et l’université de Fribourg en Suisse, entre fin 2007 et début 2014. Le point central de cette recherche concerne une classe de mobilier archéologique que sont les scories de forge, déchets métallurgiques qui se forment au fond du foyer de forge au cours du travail traditionnel d’objets en fer. Les études qui leur sont consacrées montrent que ces matériaux montrent une incroyable variabilité, qui témoigne de l’immense diversité des travaux de forge. Les recherches actuelles cherchent ainsi naturellement à établir un lien entre les scories, mises au jour par les archéologues, et les activités de forge passées. L’originalité de cette recherche est le développement d’une démarche de travail, au croisement de l’ethnoarchéologie, l’archéologie expérimentale et l’archéométrie. Ce travail a comporté une phase de terrain au Pays dogon (Mali), où forgerons et traditions métallurgiques sont encore préservés. Cette recherche de terrain a donné lieu à des expérimentations dirigées de travaux de forge, durant lesquels différents paramètres sont contrôlés. Le travail de laboratoire a permis de mettre en évidence les caractéristiques intrinsèques des scories. Toutes ces données mettent en lumière des groupes distincts de scories de forge, et constituent un référentiel unique. Raphaëlle Soulignac propose différents scenarii de modalités de formation des scories dans le foyer, en lien avec les travaux qui les ont produits. Ce travail permet ainsi d’enrichir nos connaissances sur les gestes, les pratiques des forgerons et les déchets de forgeage, en mettant en avant un patrimoine important de nos sociétés anciennes.

Abstract

This book celebrates in words and images the traditional metal crafts practised for over a thousand years by the creators of religious Buddhist statues in Nepal. The skills of these artisans are nurtured with deep respect for tradition, regarding religion, iconography and technology. Wax modellers, mould makers, casters, fire-gilders and chasers are among the specialists of the Newar ethnic group, whose work is characterised to this day by a melding of age-old technology, great skill, religious observance and contemplation. There are numerous books and exhibition catalogues dedicated to Buddhist art and iconography but little was available about the craft of the artists who turn the religious imagery into metal casts. This book fills this gap, with a thoroughly documented and historical account of the development of this “archaic” technology. The well-informed text and comprehensive photographic coverage constitute the only up-to-date account and full documentation of an art that is 1300 years old but dying out: the “ritual” production of Buddhist statues in the lost wax casting technique.The author, Dr. Alex Furger, is an archaeologist who has studied ancient metallurgy and metalworking techniques over the past four decades. He spent twenty-five years at the head of the Roman site of Augusta Raurica and lives in Basel (Switzerland). He is the author of over 130 articles in scientific journals and twelve books in the field of culture history. The fieldwork for this book led him repeatedly to Nepal, where he met and interviewed dozens of craftsmen in their workshops.This book is addressed to readers interested in culture history, travellers to Asia, collectors of statues of Buddha, (avocational) metalworkers, historians of technology, Buddhists, ethnologists, archaeologists, art historians, scholars of Asia and to libraries and museums.

Abstract

Welding technology has been taken for granted as a mature and established technology for too long. However, many new welding technologies have been included among the alternatives to joining materials. They come both from the areas of fusion and solid-state welding. Moreover, a recent approach has offered one more alternative. This is hybrid welding, which couples two or more welding sources in a cooperative or synergic welding mode. Welding engineers and scientists have the task to understand which is the best technology for a specific application. This task requires deep knowledge and great intelligence to tackle the challenge of producing light and smart structures and products.In this book, a glimpse of recent developments in metal alloy welding is presented. Laser, friction, and arc welding are the main protagonists of the papers that are included. Processes, materials, and tools are described and studied along with investigation procedures and numerical simulations.This book will make you aware of most of the subjects discussed in the scientific community and new potentialities of welding as a leading technology in manufacturing.I hope you enjoy reading this Special Issue, "Advances in Welding Metal Alloys, Dissimilar Metals and Additively Manufactured Parts".

Abstract

This study deals with the fatigue behaviour of metal-matrix-composites (MMCs) having ceramic contents of 30 to 39 Vol-%. The MMCs where produced by way of infiltrating a ceramic preform by an aluminium alloy. The characterisation of the MMC's cyclic and fatigue behaviour was researched on the basis of isothermal and thermal-mechanical fatigue tests.
