In 1936 G. T. Whyburn [8] defined an irreducible mapping to be a mapping/, of a compact metric continuum A onto B, such that no proper sub-continuum of A maps onto B under/. Similarly, assuming A to be only compact and metric, he defined / to be strongly irreducible provided that no closed proper subset of A maps onto B. J. Rozanska [7] independently defined this second type of mapping in 1937....

This article is specifically on the harm reduction programme that has been in practise in Thailand in the past as well as the present on-going project. The Thai government’s initiative in declaring war against drugs has greatly helped in this programme. The working group on HIV and Drug Risk Reduction have outlined six projects, from public awareness right up to the prevention of HIV in prisons...

Isolated scaphoid dislocations are extremely rare injuries and are commonly associated with significant ligamentousdisruptions. A dorsiflexion-supination force upon the hand is considered as the most common mechanism of injury.Different treatment options have been proposed for the management of this uncommon entity, ranging from conservativetreatment with closed reduction and casting to a wide ...

We perform a general reduction of the open membrane metric in a worldvolume direction of the M5-brane. Using reduction rules analogous to the bulk, we show that the open membrane metric leads to the standard open string metric and open string coupling constant on the D4-brane only for an “electric” reduction in which case the open membrane metric has no off-diagonal components and the Born-Infe...
