Ridge atrophy accompanied by the pneumatization of maxillary sinus in the maxillary posterior region may lead to inadequate bone height, thereby precluding implant placement. Therefore, it may be mandatory to perform a sinus membrane elevation procedure and augmentation in the bone. The present study aimed to introduce a novel modification method for sinus floor elevation using a gelatin sponge...

We consider a Markov-Chain model for Micro-Finance Institution (MFI) borrower who can be in one of four states: Applicant ($A$), Beneficiary ($B^-$ or $B^+$) small large loan, Included ($I$) the regular banking system. Given transition matrix we compute equilibrium and deduce influence probability parameters on what is profitable to within breaking-even constraints MFI. give general theorem exp...
