DERRY FELDSPAR QUARRY1

The Medical History of Derry and Londonderry

I HAVE chosen as my subject for this address-The Medical History of Derry anid Londonderry. My chief reason for doing this is that the present year has been something of an "annus mirabilis" in the life of that city as it has seen the opening of the new general hospital built from the ground on a new site at Altnagelvin and also the putting into service of new blocks and annexes for the care an...

Feldspar: Application and Implementation

The Feldspar project aims to develop a domain specific language for Digital Signal Processing algorithm design. From functional descriptions, imperative code (currently C) is generated. The project partners are Ericsson, Chalmers and ELTE, Budapest. The background and motivation for the project have been documented elsewhere [3]. We aim to raise the level of abstraction at which algorithm devel...

Leucite-Na-feldspar incompatibility: an experimental study

Phase relations at atmospheric pressure in the pseudobinary join KA1Si206 (Lc)NaA1Si3Os(Ab) and in the pseudoternary join Lc-Ab-CaA12Si2Os(An) indicate that leucite is incompatible with Na-feldspar. In the former join leucite can exist with an alkali feldspar of maximum albite content Ab54. In the Lc-Ab--An join, leucite only coexists with ternary feldspars with high An contents (approximately ...
