In this study, we compute Merrifield-Simmons index of graphs which corresponds to PL (2, n) by using the decomposition formula. Examination shows that Merri-field-Simmons certain classes deduce as a result in difference equation. Further, prominent formula for and generating function are found number n hexagons state n). Also relations formed (PL n, n)) obtained combining two with angle between...

Precision in orthodontic diagnosis can increase the chance of therapeutic success. The objective of this study was to describe the development of a computerized system (prototype), created from a printed table of the Cranial Facial Analysis and Total Dentition Space Analysis with Difficulty Index--Tweed-Merrifield Analysis--in order to aid orthodontic diagnosis. The analysis was transposed from...

The high-yielding synthesis and application of the first polymer supported reagent for the kinetic resolution (KR) of amines through enantioselective acetylation is described; this new supported chiral reagent allows the KR of primary amines with excellent selectivities at room temperature; moreover, this supported approach is highly efficient as the Merrifield-supported chiral scaffold can be ...

INTRODUCTION The esthetic balance of the face results from harmonic and symmetrical facial proportions. The literature describes several methods for lower-third facial analysis, but lacks a simple and practical method. OBJECTIVE To review the methods of analysis of the ideal projections of the chin based on soft tissues, showing the advantages and disadvantages of each. METHODS Literature r...
