BACKGROUND Botox has been used primarily for treating rhytids of the upper face. Its use in the lower part of the face has been reported by several authors but there is a relative scarcity of information regarding the use of Botox in the chin and even fewer well-controlled studies in this area. This study reports the findings from a placebo-controlled trial of Botox for the treatment of chin rh...

A new graphical method is developed to calculate the critical temperature of 2and 3-dimensional Ising models as well as that of the 2-dimensional Potts models. This method is based on the transfer matrix method and using the limited lattice for the calculation. The reduced internal energy per site has been accurately calculated for different 2-D Ising and Potts models using different size-limit...

We introduce new general iterative approximation methods for finding a common fixed point of a countable family of nonexpansive mappings. Strong convergence theorems are established in the framework of reflexive Banach spaces which admit a weakly continuous duality mapping. Finally, we apply our results to solve the the equilibrium problems and the problem of finding a zero of an accretive oper...

By generalizing the Feynman proof of the Lorentz force law, recently reported by Dyson, we derive equations of motion for particles possessing internal degrees of freedom I which do not, in general, generate a finite algebra. We obtain consistency criteria for the fields which interact with such particles. It is argued that when a particle with internal SUq(2) degrees of freedom is coupled to S...

The fi rst effective drugs against human Trypanosoma cruzi infection (nifurtimox, produced by Bayer, and benznidazole, produced by Roche) became available in the 1960s1,2. Because these drugs were initially only recommended for acute cases, the international demand for their production was very low. In the subsequent 20 years, good treatment results for chronic infection in children stimulated ...
