George Smith e la tavoletta del Diluvio / George Smith and the Flood Tablet
No full textOn December 2, 1872, an extraordinary discovery was presented at the Society for Biblical Archeology in London: a Chaldean account of the Flood, discovered in the library of Ashurbanipal in Nineveh and strikingly similar to the biblical one. The text, written in Akkadian, was part of a series of cuneiform tablets on the deeds of Gilgamesh, the hero, the builder of Uruk, the king who sought a solution to death, and who, not finding it, obtained wisdom. The author of the discovery was George Smith, a former banknote engraver and brilliant self-taught Assyriologist. The great interest shown by the newspapers for the discovery is visible in the many articles written on the subject and in the fact that it was one of them, the Daily Telegraph, to finance a new mission in northern Mesopotamia, to find the missing parts of the tablet. Two successive expeditions were funded by the British Museum, but during the latter one George Smith fell ill and died in Aleppo, unaware of the extent of his discoveries. The discussion on the relationship between Mesopotamia and the Bible continued for decades until it broke out in the controversy known as Babel-Bibel Streit in the early 20th century
The Importance of Diversity in Artificial Intelligence: Violet Turri.
No full textAcross the globe, women account for less than 30 percent of professionals in technical fields. That number drops to 22 percent in the field of artificial intelligence (AI). In this podcast from the Carnegie Mellon University Software Engineering Institute (SEI), Violet Turri, a software developer in the SEI’s AI Division, discusses the evolution of her career in AI and the importance of diversity in the field. </p

Multi-step fractionation as a tool for enhanced valorization of technical lignins: a model study
No full textThe valorisation of lignin obtained as a by-product of the pulping and biofuel industries is one of the most promising topics in the bioresource field. Despite its potential value as the only massively available aromatic biopolymer feedstock, technical lignin is nowadays mostly burnt as low cost energy source because of its chemical recalcitrance. The high heterogeneity of this material, largely dependent on the different vegetal sources and the specific biomass recovery methods, restricts its direct use and hinders also the optimization of depolymerisation approaches. The development of effective technical lignin fractionation strategies is therefore today one of the most challenging topic in the green chemistry field.
In this study, the fractionation of an industrial commercial lignin was developed by a three step procedure set-up either in aqueous or in an environmentally friendly organic solvent in order to obtain sustainable and scalable processes.1,2 The first step consisted in a microfiltration or a Soxhlet extraction, depending on the type of solvent used. Then a cascade membrane-mediated ultrafiltration allowed to obtain at the end three refined lignin fractions. The parent lignin and the different lignin fractions were fully characterized.
The two-step process reported here allows accessing lignin fractions with well-defined physico-chemical properties (including mass distribution, glass transition temperature, aliphatic and phenolic hydroxyl groups concentration, syringyl/guaiacyl unit ratio) and represents a valuable approach towards the development of bio-based polymers and the preparation of key platform chemicals, thereby paving the way for an effective exploitation and valorization of this remarkable resource.

Knowledge and the Norm of Assertion : An Essay in Philosophical Science
No full textLanguage is a human universal reflecting our deeply social nature. Among its essential functions, language enables us to quickly and efficiently share information. We tell each other that many things are true—that is, we routinely make assertions. Information shared this way plays a critical role in the decisions and plans we make. In Knowledge and the Norm of Assertion, a distinguished philosopher and cognitive scientist investigates the rules or norms that structure our social practice of assertion. Combining evidence from philosophy, psychology, and biology, John Turri shows that knowledge is the central norm of assertion and explains why knowledge plays this role. Concise, comprehensive, non-technical, and thoroughly accessible, this volume quickly brings readers to the cutting edge of a major research program at the intersection of philosophy and science. It presupposes no philosophical or scientific training. It will be of interest to philosophers and scientists, is suitable for use in graduate and undergraduate courses, and will appeal to general readers interested in human nature, social cognition, and communication
