To enable shaped preforms to be produced accurately, it is essential to have a full understanding of the geometrical properties of the structure and the effects that the various shaping techniques produce. This publication discusses the technique of threedimensional shaping and its affects on the geometrical dimensions of a hemispherical form. In the paper the calculation procedures employed to...

Since the seminal production of Noblit and Hares’ book Meta-ethnography published in 1988, the quest for an optimal route to synthesising qualitative evidence has gained momentum. Theoretical arguments in this area range diametrically from the impossibility of progressing knowledge based on qualitative evidence in the absence of such synthesis, to the impossibility of synthesising knowledge tha...
