In this paper we prove some results on Reuleaux triangles in (Minkowski or) normed planes. For example, we reprove Wernicke’s result (see [21]) that the unit disc and Reuleaux triangles in a normed plane are homothets if and only if the unit circle is either an affine regular hexagon or a parallelogram. Also we show that the ratio of the area of the unit ball of a Minkowski plane to that of a R...

A series of 18 cases of tuberculous encephalopathy (TBE) in children studied between June 1983 and October 1984 at Queen Elizabeth Hospital, Kota Kinabalu is presented. The data suggest that: the incidence is not as rare as previously thought; the occurrence of TBE is related to the absence of BCG vaccination; the presentation is often late; laboratory data, although helpful is not often confir...
