Microstructures of deformed calcite in marble from the Bergell Alps are studied by using a microfocused polychromatic synchrotron X-ray beam. The high spatial resolution, together with orientation and strain resolutions, reveals twin plane orientation, multiple twin lamellae, and strain distributions associated with the twins. Single and multiple mechanical twins on e 1⁄4 0118 systems are confi...

Introduction In the night between the 11th and the 12th of April 1997 a fire heavily damaged the “Sacra Sindone” Chapel of the Turin cathedral. One of the restoration steps following the accident consists of the substitution of the irreparably damaged marble blocks covering the inner surfaces of the Chapel dome. We show the results of a research aimed to localize joints in the blocks of “Bigio ...

This study investigated the effect of being imitated on the behavior of preschool children. Twenty-two children were employed in a " marble game," thick consisted of dropping a marble into one of three holes in a wooden box. Procedure trials occurred across four phases in an ABAB design: baseline, imitation, reversal, and imitation again. During the two treatment phases, the subject's responses...

We explore how to enable robots to rapidly learn from watching a human or robot perform a task, and from practicing the task itself. A key component of our approach is to use small units of behavior, which we refer to as behavioral primitives. Another key component is to use the observed human behavior to define the space to be explored during learning from practice. In this paper we manually d...

BACKGROUND By adding new levels of experience, mobile Augmented Reality (mAR) can significantly increase the attractiveness of mobile learning applications in medical education. OBJECTIVE To compare the impact of the heightened realism of a self-developed mAR blended learning environment (mARble) on learners to textbook material, especially for ethically sensitive subjects such as forensic me...

Two outbreaks of marble spleen disease were observed in pen-raised pheasants in Ontario on the same farm in the summer of 1971 and in 1972. In both instances, a mortality of 3% per day lasted for approximately 14 days. Fifteen birds were necropsied and tissues removed and examined histologically and by electron microscopy. In addition splenic material was injected into adult pheasants. The gros...

An important application of laser range sensing is found in the 3D scanning and modelling of heritage collections, and of sculptures in particular. Since a significant proportion of the statues in the world’s museums is composed of marble, the optical properties of this material under laser range sensing need to be understood. Marble’s translucency and heterogeneous structure produce significan...

In order to investigate the influence of 3D morphology parameters of marble joint surface on its mechanical and seepage characteristics, artificial joints of coarse-grained marbles were scanned by Tianyuan OKIO-typed 3D laser scanner; and then, the professional software was used to obtain the 3D morphology parameters of marble joint surface. Tests of water flowing through a single joint were co...
