Sport in Wales is a team sport – related to hockey, hurling, shinty, and bandy – which was first recorded in Wales in the eighteenth century. The game is played on a large level field between teams of up to thirty players each of them equipped with a "bando": a curve-ended stick resembling that used in field hockey. Although no formal rules are known, the objective of the game was to strike a ball between two marks which served as goals at either end of the pitch. Popular in Glamorgan in the nineteenth century, the sport all but vanished by the end of
Wide-field multiphoton microscopy all the elements of the formula_4 tensor thanks to the capability of being able to change the polarisation of each beam independently. Wide-field multiphoton microscopy Wide-field multiphoton microscopy refers to an optical non-linear imaging technique tailored for ultrafast imaging in which a large area of the object is illuminated and imaged without the need for scanning. High intensities are required to induce non-linear optical processes such as two-photon fluorescence or second harmonic generation. In scanning multiphoton microscopes the high intensities are achieved by tightly focusing the light, and the image is obtained by stage- or beam-scanning the sample. In wide-field
