INTRODUCTION The aim of the study was to investigate the occurrence, the aetiology and the management of congestive heart failure in the cardiac centre of the St. Elizabeth catholic general hospital Shisong in Cameroon. METHODS Between November 2002 and November 2008, a population of 8121 patients was consulted in the referral cardiac centre of St. Elizabeth Catholic General Hospital. Of thes...

Recently, it has been proposed that the fundamental scale of quantum gravity can be close to the weak scale if there are large extra dimensions. This proposal has important phenomenological implications for processes at the TeV scale. We study the process γγ → γγ, assuming an ultraviolet cutoff M S ∼ 1 TeV for the effective gravity theory. We find that, at center of mass energies √ s ∼ 1 TeV, t...
