Compared with other mammals, multiple births are rare in humans. The attitude towards multiple births varies widely among cultures. Although expected to be present, evidence for twin burials from prehistoric times is scarce. However, knowledge about the attitude of ancient societies towards twins, a

We demonstrate the tuning of the diffraction efficiency in a polymer-dispersed liquid crystal (PDLC) diffraction grating by mechanical shear deformation. We chose a photocurable thermoset with elastic mechanical properties as the host material to demonstrate the tuning effect. Raman-Nath gratings we
## Abstract The deformation of a glassy amorphous polymer has been simulated by Monte Carlo. A molecular model with constrained chemical bonds (rigidβbond model) and one with chemical bonds represented by Gaussian springs (flexibleβbond model) have been compared. Furthermore, two different deformat
The writer was very interested in the reported results and would like to add additional comments on the subject of mortaraggregate bond strength. The authors' conclusion concerning the insensitive nature of the friction component of bond strength when various polymer additives are used agreed with
Pratt and Schlaifer's (1984, 1988) research employed in efforts to produce laws in economics are considered and their use in predicting future data is described. Data for Australia are used to illustrate the approaches.
