No treatise on metal casting production would be complete without reference to the most widely used moulding and coremaking media — sand. With the vast range of sand moulding and coremaking processes available, perhaps the engineer today could be excused if he feels this facet of casting production should be termed ‘granular witchcraft’. However, there

The inadequacy of verbal development is the most striking handicap to the analysis of children. In the young child, under seven years, many concepts such as “happy,” “sad,” and “worried” are frequently not recognized at all; the child's very vocabulary is too limited for expressive purposes.

In this paper we introduce sand automata in order to give a common and useful framework for the study of most of the models of sandpiles. Moreover we give the possibility to have sources and sinks of "sand grains". We prove a result which shows that the class of sand automata is rich enough to simulate any reasonable model of sandpiles based on local ...

The physics of wind-blown sand poses a variety of intriguing problems whose proper solution seems to require statistical ideas and methods, partly new. The main traits of the processes of transport and sorting of sand particles by wind or by water are described, and a review is given of results obtained and of subjects for further study.

Books of Sand are interactive installations that relate the movement of hands in the sand to hypertexts containing Jorge Luis Borges texts taken from the Web. It consists of one or more glass buckets full of sand that when touching it with the hands, projected codes retrieved from the Web arise interacting with the movement of the hands.A video camera ...

Many desert sand dunes emit a loud sound with a characteristic tremolo around a well-defined frequency whenever sand is avalanching on their slip face. This phenomenon, called the 'song of dunes', has been successfully reproduced in the lab, on a smaller scale.
