Total maxillary advancement with and without bone grafting.

Computer morphometrics was used to analyze 21 adult patients who underwent total maxillary advancement; ten had bone grafting behind the tuberosity and 11 did not. Each group was subclassified as those with idiopathic maxillary deficiency and those with cleft lip and cleft palate; all patients were treated by the same basic operative technique. The results of the study indicate that those patients who had bone grafts had optimum stability. However, individuals with maxillary deficiency who undergo minimal advancements (less than 0.5 mm) can have overcorrections at surgery and, therefore, do not require bone grafts for good stability.

Optimal design of an enzymatic reactor for flow injection analysis.

A simulation procedure for the optimization of enzymatic reactors used in sandwich flow injection systems is evaluated. The system is modeled as a plug-flow reactor with axial dispersion. To calibrate it, dispersion coefficients can be evaluated using residence time distribution techniques; meanwhile, enzymatic kinetics must be determined for the system considered, according to the values of the substrate conversion attained. The model has been linked to an optimization routine based on the Powell algorithm. The proposed approach has been evaluated in a system performing simultaneous determinations of glucose and glycerol, considered the common carbon sources in a fermentation process.
