Damage on starch from processing Andean food plants
No full textMany of the cultivated plant species in the world originated in the Americas, the Andean Area being one of the most prolific regions. Among the food crops there are tubers, cereals, pseudocereals, and legumes. Many procedures for preserving, processing and cooking of these Andean starchy resources are necessary to make them edible and may be tracked far away in time. These procedures generate physicochemical changes in starchy materials that modify the degree of cristallinity, completeness and appearance of some of their starch grains. Knowledge of how starch may be culturally modified is of interest for Archaeology because it enhances the possibility of recognizing cultural actions by analyzing damaged grains in tools and sediments from archaeological samples.Fil: Babot, Maria del Pilar.

Unpacking the Collection: Networks of Material and Social Agency in the Museum
No full textMuseum collections are often perceived as static entities hidden away in storerooms or trapped behind glass cases. By focusing on the dynamic histories of museum collections, new research reveals their pivotal role in shaping a wide range of social relations. Over time and across space the interactions between these artefacts and the people and institutions who made, traded, collected, researched and exhibited them have generated complex networks of material and social agency.
In this innovative volume, the contributors draw on a broad range of source materials to explore the cross-cultural interactions which have created museum collections. These case studies contribute significantly to the development of new theoretical frameworks to examine broader questions of materiality, agency, and identity in the past and present.
Grounded in case studies from individual objects and museum collections from North America, Europe, Africa, the Pacific Islands, and Australia, this truly international volume juxtaposes historical, geographical, and cross-cultural studies.
This work will be of great interest to archaeologists and anthropologists studying material culture, as well as researchers in museum studies and cultural heritage management
Landscapes of exchange in the Willaumez Peninsula, West New Britain, Papua New Guinea
No full textThe well preserved tephrostratigraphy stretching across the Willaumez Peninsula in West New Britain, Papua New Guinea provides a unique opportunity to monitor landscapes of cultural exchange over a considerable period of human history, extending from the Pleistocene to the recent past. An approach integrating pXRF geochemical characterisation and measurements of reduction intensity was used to analyse a substantial sample of obsidian artefacts from the FRI site and 25 test pits in the Isthmus region, located at the base of the Willaumez Peninsula. Exchange is shown to have been a persistent feature of social life, but variations in the mix of sources used and the kinds of objects transferred also indicate changes in how networks were constructed by social groups. As the frequency and severity of volcanic events decreased through time and population rose in response, the importance of obsidian for creating links may have diminished in favour of other objects, such as stone axe blades.Fil: Bonnat, Gustavo Federico.

Chip-Firing Revisited: A Peek into the Third Dimension
No full textChip-firing was first introduced as a probabilistic game. Subsequently, it was generalized to arbitrary graph configurations and investigated mostly with regard to two-dimensional quad-grid layouts. In this paper, we lift chip-firing to the third dimension. Aside from the arising three-dimensional shapes, we are interested in the internal, two-dimensional structures. Furthermore, we explore the different shapes obtained by chip firing processes on various neighborhoods, such as the face-centered and the cube-centered grid as well as on a neighborhood inspired by knight moves.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Computer Graphics and Visualisatio
